DETAILED DESCRIPTION OF THE INVENTION

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those of ordinary skill in the art that the invention may be practiced without these specific details. In other instances, well- known methods, procedures, components, modules, units and/or circuits have not been described in detail so as not to obscure the invention. Some features or elements described with respect to one embodiment may be combined with features or elements described with respect to other embodiments. For the sake of clarity, discussion of same or similar features or elements may not be repeated.

Although embodiments of the invention are not limited in this regard, discussions utilizing terms such as, for example, “processing”, “computing”, “calculating”, “determining”, “establishing”, “analysing”, “checking”, or the like, may refer to operation(s) and/or process(es) of a computer, a computing platform, a computing system, or other electronic computing device, that manipulates and/or transforms data represented as physical (e.g., electronic) quantities within the computer’s registers and/or memories into other data similarly represented as physical quantities within the computer’s registers and/or memories or other information non-transitory storage medium (e.g., a memory) that may store instructions to perform operations and/or processes. Although embodiments of the invention are not limited in this regard, the terms “plurality” and “a plurality” as used herein may include, for example, “multiple” or “two or more”. The terms “plurality” or “a plurality” may be used throughout the specification to describe two or more components, devices, elements, units, parameters, or the like. Unless explicitly stated, the method embodiments described herein are not constrained to a particular order or sequence. Additionally, some of the described method embodiments or elements thereof can occur or be performed simultaneously, at the same point in time, or concurrently. Unless otherwise indicated, the conjunction “or” as used herein is to be understood as inclusive (any or all of the stated options).

Some aspects of the invention may be related to dispersible wipes that are fully dispersible in sewage water but still strong enough to be pulled out from a package in an everyday use. It will be understood that the following terms are synonymous with the meaning of “dispersible” within the context of this invention: “flushable”, “disintegrable”, “dissolvable”, “soluble”, “biodegradable” “compostable”, and “decomposable”.

Some embodiments of the following invention are described as being suitable for or configured for dispersible wipes. It will be recognised that these embodiments may also operate with non-dispersible wipes.

Packages of wet wipes according to embodiments of the invention may have shelf life longer than 1 year (e.g., 1.5 years, 2 years and more), during which the packed wet wipes may lose some of their mechanical strength.

Reference is made to Figure 1 showing a non-limiting example of a despersible, which is a cross- sectional view of a dispersible wipe according to some embodiments of the invention. Wipe 100 may include a thin lightweight polymeric mesh 102 that is comprised of dispersible filaments and at least one fibrous layer 104 including flushable fibres laminated to at least one side of thin polymeric mesh 102.

In some embodiments, two fibrous layers 104 may be laminated on each side of thin polymeric mesh 102 (as illustrated).

In some embodiments, wipe 100 may further include a wetting lotion (not illustrated). In some embodiments, thin polymeric mesh 102 may be configured to bind fibres of fibrous layer 104 and remain intact when wipe 100 contains liquid at an amount of at most 400% of the mass/weight of the laminated fibrous layer 104 and to disperse in excess water if the amount of the water exceeds 500% of the weight of laminated fibrous layer 104.

Reference is now made to Figures 2A-2E, which show various embodiments in which multiple dispersible wipes, or a long continuous ream of dispersible wipe material may be configured for storage and use.

Figures 2 A and 2B show a long reams of dispersible wipe material, 200A and 200B, which are in the form of a roll. The rolls may be configured to be mounted on a roller, for example a roller within a repository for storing dispersible wipes in a dry form. Figure 2A shows a roll of dispersible wipe material 200A in a continuous uncut and unperforated form.

Figure 2B shows a roll of dispersible wipe material 200B in a perforated form, in which lines of perforation 202 extend across the width of the dispersible wipe material. For example, the lines of perforation may be parallel to an axis of rotation of the roll. Lines of perforation may be areas of material in which a number of small holes are made. These small holes may allow for the dispersible wipe material to be easily torn or ripped along the line of perforation.

Figures 2C-2F show multiple dispersible wipes, 200C and 200D, consisting of separate sheets of dispersible wipe material.

Figures 2C and 2D show dispersible wipes that have been folded or creased along their width or length. For example, each dispersible wipe may be folded twice, with one fold in the opposite direction to the other fold, in order to form the cross-sectional shape of a Z (or backwards Z). A first wipe of this shape 204 may be configured to receive in a folded opening, a portion of a second wipe 206, as can be seen in Figure 2D. A large number of wipes may be linked up in this way to form a linked stack of wipes. A linked stack of wipes may be advantageous over a stack of unfolded and unlinked wipes since a linked stack may be more likely to maintain its structure during installation and transit. A linked stack may also be advantageous since wipes may be easily removed from the bottom of the stack.

Figures 2E and 2F show dispersible wipes 208 in unfolded sheets. The unfolded sheets may be combined into a stack of wipes.

Reference is now made to Figure 3, which shows a device for simultaneously dispensing and wetting dispersible wipes 300 according to some embodiments of the invention.

The device may comprise a repository for storing dispersible wipes in a dry form 302. The repository for storing wipes in a dry form may be adapted to store wipes of certain configurations. For example, the repository may include a roller configured to have a roll of dispersible wipes mounted and rolled thereon. The repository may be adapted to store wipes of multiple different configurations.

The device may comprise a wetting area 304, which comprises a means for wetting the dispersible wipes with at least one liquid or liquid solution. The means for wetting the dispersible wipes may take various forms. The means for wetting may be configured to wet the dispersible wipes during dispensing of the dispersible wipes. The means for wetting may additionally or alternatively be configured to wet the dispersible wipes before dispensing of the dispersible wipes. In the case that the wipes are configured to be wet before dispensing, it will be appreciated that the wetting of the wipes would happen only a relatively short time before dispensing, such that the wipes maintain much the same structural integrity after being dispensed. In some embodiments, wetting of the dispersible wipes is configured to take place immediately before the dispensing of the dispersible wipes.

The device may comprise at least one container 306 for storing at least one liquid or liquid solution suitable to wet the dispersible wipes. The container may be of the form of a liquid tank. The container may contain a means for refilling with at least one liquid or liquid solution.

In other embodiments, at least one liquid or liquid solution may be stored externally to the device and configured to be conveyed into the device, for example, through a pipe. For example, if one of the at least one liquids is water, then the device may be connected to an external water system, and there may not be a need for a container for storing water.

The at least one liquid or liquid solution may be selected based on the intended use of the dispersible wipes once wetted and dispensed. For example, for most uses of wet wipes, at least one of the liquid or liquid solutions may be water. For example, many wet wipes intended for use as disinfectant wipes are wetted with isopropyl alcohol. For another example, many wet wipes intended for use in personal and infant hygiene may be wetted with a fragrance or parfum, either in liquid form, or as a solution in another liquid. Further examples of substances used to wet wipes include: soap, rheology modifier, friction reducing agent (to create a gliding feeling), surfactant, an acid or alkaline (e.g., citric acid), complementary emollients, emulsifiers, and/or preservatives. It will be understood that the examples of liquid and liquid solutions above are intended as examples only and in no way intended to be limiting. It will be understood that uses of wet wipes and the possible liquid or liquid solutions that are used to wet said wipes extend well beyond those disclosed above, and these further examples would be readily apparent to the skilled person.

The device may comprise a means 308 for conveying the at least one liquid or liquid solution from the at least one container to the wetting area. The means may comprise at least one pipe or tube. The pipe or tube may be connected to the at least one container and to the wetting area.

The device may additionally comprise a repository 310 for a wetted dispersible wipe section. A user may be able to retrieve a wetted wipe section from the repository for a wetted wipe section.

The device may additionally comprise a means for dispensing the dispersible wipes. The means for dispensing may be located in the repository for storing dispersible wipes in a dry form 302, the wetting area 304, and/or the repository for a wetted dispersible wipe section 310. Additionally or alternatively, the means for dispensing may be located in a separate area within or outside of the device.

Reference is now made to Figures 4A-4D which show examples of at least part of means for dispensing according to some embodiments of the invention.

Figure 4A shows a device with a manual means for dispensing 400A. An external body 412, such as a human hand, may pull on an exposed area of dispersible wipe. The dispersible wipe material is configured to be dispensed when a force is applied to the dispersible wipe section by the external body. The force may pull the dispersible wipe through the device.

Figure 4B shows a device with a lever means for dispensing 400B. A lever 402 is mounted onto an exterior wall of the device. The lever is in operable communication with at least some internal means for dispensing the dispersible wipes. In a non-limiting example, internal means for dispensing may comprise, a number of cogs, gears or belts in operable communication with the lever, with each other, and with, for example, a number of rollers. Pulling of the lever (for example, as shown by the arrow) may thus cause the number of rollers to rotate, wherein the rollers are in contact with the dispersible wipe material and may convey the wipe material through the device. Figure 4B also shows an optional repository for a wetted dispersible wipe section 410, from which a dispersible wipe section may be retrieved.

Figure 4C shows a device with a push-button means for dispensing 400C. A push-button 404 is mounted onto an exterior wall of the device. The push-button is in operable communication with at least some internal means for dispensing the dispersible wipes. In a non-limiting example, internal means for dispensing may comprise, a number of processing units, wires or electric cables, electric motors, batteries, cogs, gears or belts in operable communication with the push-button, with each other, and with, for example, a number of rollers. Pushing the push-button may thus cause the number of rollers to rotate, for example, driven directly or indirectly by the number of electric motors, wherein the electric motors are instructed to rotate by a processing unit after the processing unit receives a signal indicative of a push on the push-button, and wherein the rollers are in contact with the dispersible wipe material and may convey the wipe material through the device.

Figure 4D shows a device with a sensor means for dispensing 400D. A sensor 406 is mounted onto an exterior wall of the device. The sensor is in operable communication with at least some internal means for dispensing the dispersible wipes. In a non-limiting example, internal means for dispensing may comprise, a number of processing units, wires or electric cables, electric motors, batteries, cogs, gears or belts in operable communication with the sensor, with each other, and with, for example, a number of rollers. A stimulus sensed by the sensor may thus cause the number of rollers to rotate, for example, driven directly or indirectly by the number of electric motors, wherein the electric motors are instructed to rotate by a processing unit after the processing unit receives a signal indicative of a sensed stimulus, and wherein the rollers are in contact with the dispersible wipe material and may convey the wipe material through the device.

The sensor 406 may be an infrared sensor, wherein a stimulus may be an external body that emits infrared light, such as a human hand (as pictured). The sensor may additionally or alternatively be configured to sense different wavelengths of electro -magnetic radiation, such as visible light. The sensor may additionally or alternatively be configured to sense sound or vibrations. A sound sensor may allow for voice activation of wipe dispensing.

A device with sensor means for dispensing may advantageously allow for contactless dispensing of dispersible wipes. This may for example limit the spread of disease, for example in a clinical setting. Reference is now made to Figures 5A and 5B which show aspects of the means for dispensing and means for wetting according to some embodiments of the invention. In some embodiments, the apparatus of Figures 5A and 5B may be substantially located in the area for wetting.

Figures 5A and 5B show cross sections of two rollers, 514 and 520. Each roller may have a broadly or substantially circular cross-section. Each roller may be an elongated broadly cylindrical shape with a substantially circular cross section. It will be understood that each roller may have a differently shaped cross section, so long as the rollers are able to convey a dispersible wipe section between them. The elongated shape may, for example, be longer or may be the same length as the width of the dispersible wipe material, in order that all parts of the dispersible wipe material may come into contact with the rollers during dispensing. The rollers may be configured to rotate around an axis of rotation. The axis of rotation may be configured to lie along the elongated length of the roller. The axis of rotation may intersect the substantially circular cross section at an intersection point. The intersection point may be located substantially in the centre of the substantially circular cross section.

Figures 5A and 5B show a first roller 520 and a second roller 514. The rollers need not be of the same size. For example, the first roller may be smaller than the second roller. This may be advantageous in that it may help with space savings in the device. Alternatively, the rollers may be of a similar size. This may be advantageous, since manufacturing one size of roller may save costs compared to manufacturing multiple sizes of roller.

In embodiments 500A and 500B of figures 5A and 5B, the second roller is a partially wet roller 514. The partially wet roller comprises at least one first section of its surface 516 which is configured to provide a means for wetting the dispersible wipes with the at least one liquid or liquid solution (the at least one first section is indicated with diagonal shading). The first section 516 may in some embodiments be constructed of an absorbent, porous, or permeable material. The absorbent material may, for example, comprise a sponge material or a fabric material. In some embodiments, the absorbent material of first section 516 may be mounted upon, or around the outside of, a nonabsorbent inner material. The non-absorbent inner material may be stronger than the absorbent material, and may advantageously maintain the structural integrity of the partially wet roller. The first section of the surface of the partially wet roller may be wetted via at least one pipe leading from the at least one container storing at least one liquid. The first section may then transfer liquid to the dispersible wipe material through contact with the dispersible wipe material. Contact between the first section 516 and the dispersible wipe or dispersible wipe material may take place during dispensing. Most or all contact between the first section and the dispersible wipe or wipe material may take place at or proximal to the location and time wherein the dispersible wipe material is in contact with both the first and second rollers. In some embodiments, the first and second rollers may be configured such that a force is applied to the second roller by the first roller and the dispersible wipe material during dispensing (or equivalently, a force is applied to the wipe material by the rollers). Said force may optimally increase the amount of liquid or liquid solution transferred from the first section 516 to the dispersible wipe material during dispensing (for example, by squeezing the absorbent material of 516).

The partially wet roller 514 may additionally comprise at least one second section of its surface 518 (the at least one second section is indicated in a solid black colour). The second section of the surface of the roller 518 may not provide a means for wetting the dispersible wipes. The second section may provide a means for holding a section of the dispersible wipes between itself and the first roller, without the held section of dispersible wipe material dispersing. In some embodiments, the second section is constructed from a different material to the first section. In some embodiments, the second section advantageously comprises a smaller portion of the surface of the partially wet roller than the first section. This may allow greater/easier transfer of the at least one liquid or liquid solution onto the dispersible wipe material.

Figure 5A shows an embodiment of the partially wet roller with one first (partially wet) section of the surface and one second section of the surface. Figure 5B shows an embodiment of the partially wet roller with two first (partially wet) sections of the surface and two second sections of the surface. Rollers 514 and 520 may be configured to rotate in order to convey the dispersible wipe material 522 through the device and dispense the dispersible wipe. The rollers may be configured to rotate in opposite directions. For example, from the point of view of Figures 5A and 5B, the first roller 520 may be configured to rotate in an anticlockwise (counterclockwise) direction and the second roller 514 may be configured to rotate in a clockwise direction. Thus, the dispersible wipe section may be conveyed leftwards from the perspective of Figures 5 A and 5B. Optionally, the dispensing may be additionally achieved through any of the embodiments 400 A, 400B, 400C, or 400D.

In some embodiments, when no dispersible wipe material needs to be dispensed and/or when no dispersible wipe material is being dispensed, the rollers are stationary (not rotating). When in a stationary mode, the rollers optimally are in the position indicated in Figures 5 A and 5B, wherein second section 518 and roller 520 are in alignment and in contact with a (possibly dry) section of the dispersible wipe material 522. Second section 518 and roller 520 may be configured to hold the dispersible wipe section between them. Second section 518 and roller 520 may be configured to hold the dispersible wipe, such that the dispersible wipe section does not become substantially wet when in the stationary mode. Hence, in this embodiment, the dispersible wipe material may not disperse or break down, while still yet to be dispensed and within the machine.

The first roller and partially wet roller of these embodiments (500A and 500B), as well as other embodiments (e.g., 700, 800, and 1700), provide a way of substantially reducing the number of required components to both dispense and wet the dispersible wipes. This may lead to more straightforward maintenance, space savings and cost savings over other approaches.

Reference is now made to Figures 6A and 6B, which show a device for simultaneously dispensing and wetting dispersible wipes 600 according to some embodiments of the invention. In particular, embodiment 600 may incorporate any double roller embodiment of the present invention, for example, embodiments 500A, 500B, 700, 800, or 1700. Alternatively, embodiment 600 may incorporate any other means for dispensing, wetting, and/or cutting (not pictured).

The device may comprise a repository for storing dispersible wipes in a dry form 602. The repository for storing wipes in a dry form may be adapted to store wipes of certain configurations. In a nonlimiting example, the repository may include a roller 628 configured to have a roll of dispersible wipes 626 mounted and rolled thereon. The repository may be adapted to store wipes of many different configurations.

The device may comprise at least one container 606 for storing at least one liquid or liquid solution suitable to wet the dispersible wipes. The container may be of the form of a liquid tank. The container may contain a means for refilling with at least one liquid or liquid solution. Additionally or alternatively, the container may be configured to be easily replaced with a new container (for example, when the container is empty).

The device may additionally comprise a repository for a wetted dispersible wipe section 610. A user may be able to retrieve a dispensed wetted wipe section from the repository for a wetted wipe section. The dispensed wetted wipe section may be separate from other dispersible wipe material. Alternatively, the dispensed wipe section may need to be ripped apart from other dispersible wipe material, for example, along a line of perforation.

The device may comprise a first roller 620 and a second roller 614, wherein the rollers are configured to convey and dispense a portion of the dispersible wipe material or a dispersible wipe through the device. The second roller 614 may be a partially wet roller, configured to wet the dispersible wipe material through contact during dispensing of the wipe or wipe material. Dry dispersible wipe material 622 may be conveyed between the first and second rollers and hence become wet dispersible wipe material 624. Wet dispersible wipe material may be dispensed into/onto a repository for a wetted dispersible wipe section 610. The device may comprise a means 608 for conveying the at least one liquid or liquid solution from the at least one container to the partially wet roller or other means for wetting. The means for conveying may comprise at least one pipe or tube. The pipe or tube may be connected to the at least one container and to the partially wet roller or other means for wetting. The means for conveying liquid or liquid solution may ensure that the means for wetting, such as a partially wet roller, is evenly wetted along its length, such that subsequent wetting of the dispersible wipe material is also evenly wetted along its width.

The device may additionally comprise at least one directing roller 630. The device may comprise this directing roller and other rollers in order that the dispersible wipe material is conveyed through the device in an optimal manner, for example, to direct the dispersible wipe material into the means for wetting at the correct height/level, to avoid the dispersible wipe section becoming wet and dispersing prior to dispensing by avoiding surfaces that may be wet, and to avoid the dispersible wipe material from rubbing against a hard surface, which could rip or damage the dispersible wipe material.

It will be recognised that Figure 6A may show the device during its dispensing mode, wherein the rollers are rotating to dispense the dispersible wipes or dispersible wipe material. The partially wet roller is additionally wetting the dispersible wipe material which it makes contact with. In some embodiments of the invention, it would not be advisable to keep the device in a stationary mode in which the components of the device are in the exact configuration of Figure 6A. The portion of dispersible wipe material held between the first roller 620 and the partially wet roller 614 would become substantially wet. After some time in this position, this portion of the partially wet wipe may begin to disperse or break down. The dispersible wipe material would then likely break, with the dry section of dispersible wipe material falling away from the first roller and partially wet roller. The device would then require maintenance to reinsert the dispersible wipe material between the rollers. It will be further recognised that Figure 6B shows the device during its stationary mode, wherein the dispersible wipe material is held between the first roller 620 and the partially wet roller 614 without dispersing.

Reference is now made to Figures 7 A and 7B which show aspects of the means for dispensing and means for wetting according to some embodiments of the invention. In some embodiments, the apparatus of Figures 7A and 7B may be substantially located in the area for wetting.

Figures 7A and 7B show a similar apparatus to Figures 5A and 5B. As in Figures 5A and 5B, Figures 7 A and 7B show a first roller 720 and a second roller 714. The second roller 714 may be a partially wet roller, comprising at least one first section of its surface 716, which is configured to provide a means for wetting the dispersible wipes with at least one liquid. The second roller may additionally comprise at least one second section of its surface 718 which is configured to hold a section of dry dispersible wipe material 722 between itself and the first roller. The second roller is configured to rotate substantially around an axis of rotation 732. In some embodiments, an axel may enable rotation by running along at least part of the axis of rotation. Each roller operates in a substantially similar manner to the rollers of Figures 5 A and 5B.

Embodiment 700, however, is different in that the second section of the surface of the second partially wet roller is configured to protrude outwards from the substantially circular cross-section of the roller. The protrusion 718A advantageously results in a stationary state of the two rollers in which the dispersible wipe material is held away from the first section of the surface of the partially wet roller. This may result in the dispersible wipe material being less likely to become wet in the stationary mode. Additionally, or alternatively, the second section 718 and 718A may not be required to be as large as in embodiments in which there is no protrusion 718A (i.e., the second section may occupy a smaller portion of the total surface of the partially wet roller). This may allow for more complete wetting of the dispersible wipe material during wetting and dispensing. The stationary mode of embodiment 700 is shown by way of example in Figure 7A. The dispensing and wetting mode of embodiment 700 is shown by way of example in Figure 7B.

Arrows 700B and 700C show the rotation of the first roller 720 and second roller 714 to convey and dispense the dispersible wipe material between them. The dispersible wipe material is wetted through contact with the first section of the surface of second roller 716. Arrow 700A shows that, in some embodiments wherein the second roller has protrusion 718A, one of or both of the rollers should be configured to maintain contact or pressure on the dispersible wipe section when during dispensing, as well as when stationary. Multiple methods exist to maintain contact or pressure. For example, one or both rollers may be constructed of a material which is configured to deform under some pressure (e.g., elastic deformation), such that the rollers are in contact during rotation/dispensing, and are also in contact in the stationary state, but wherein in the stationary state, at least one of the rollers is deformed. By way of another example, one or both rollers may be configured to move translationally towards or away from the centre of the other roller, in order that the rollers remain in contact with the dispersible wipe material. A pushing mechanism, such as a spring, may push at least one of the rollers into contact with the dispersible wipe material. In Figure 7B, the first roller 720 is configured to move translationally to maintain contact with the dispersible wipe material.

Reference is now made to Figures 8A and 8B which disclose an embodiment 800, which shows aspects of the means for dispensing and means for wetting according to some embodiments of the invention. In some embodiments, the apparatus of Figures 8A and 8B may be substantially located in the area for wetting. As in embodiments 500A, 500B, and 700, embodiment 800 contains two rollers, 814 and 820, wherein each roller may have a broadly or substantially circular cross-section. The second roller 814 may be a partially wet roller, comprising at least one first section of its surface 816, which is configured to provide a means for wetting the dispersible wipes with at least one liquid. The rollers are configured to convey and dispense the dispersible wipe material between, while the second roller 814 is configured to additionally wet the dispersible wipe material. Figure 8B shows embodiment 800 in a dispersing and wetting mode. Arrows 800B and 800C show the rollers rotating to convey through contact a section of dispersible wipe material between them.

Figure 8A shows embodiment 800 in a stationary mode, wherein the dispersible wipe section is not being dispensed or wetted. Second roller 814 may be configured to retract or move translationally out of contact/operation with the dispersible wipe section and the first roller 820 (as pictured). Additionally or alternatively, the first roller 820 may be configured to retract or move translationally out of contact/operation with the second roller 814. In some embodiments, the first roller is substantially below the second roller, such that the dispersible wipe section maintains contact with the first roller and does not maintain contact with the second roller (which is partially wet). Retraction of roller 814 is achieved in some embodiments through axel 834, about which the second roller rotates during dispensing 800B. The axel may be located in axel housing 836, which allows for the movement of the second roller with respect to the fixed position of the axel. Arrow 800A shows the second roller being moved into contact with the dispersible wipe material before dispensing. This is optionally achieved by moving the second roller and its axel housing down along the axel into its rotatable position.

Reference is now made to Figures 9 A, 9B, and 9C which show aspects of the means for dispensing and means for wetting according to some embodiments of the invention. Figures 9 A, 9B, and 9C show a partially wet roller 914 with at least one surface 916 configured to provide a means for wetting the dispersible wipes. Also shown is a spring-mounted assembly 946 configured to be in contact with a section of the dispersible wipe material (in dry form 922 or possibly wet form 924), configured to hold the section of the dispersible wipe material out of contact with the partially wet roller when not during dispensing, and further configured to be depressed by the means for dispensing during dispensing to allow a portion of the dispersible wipe material to be in contact with the partially or fully wet roller. The spring-mounted assembly may be mounted to the rest of the device via a spring 938 (or other elastic means) as well as axel housing 940 through which an axis of rotation of the spring mounted assembly 942 passes, and into which an axel (or equivalent) (not pictured) may be inserted. Spring-mounted assembly may have a pivoting end, which aligns with axel housing 940 and wipe interaction end, which is situated at or near the partially wet roller 914. Dispersible wipe material is configured to pass over one side (e.g., the upper side) of the wipe interaction end of the springmounted assembly, whereas the partially or fully wet roller is configured to be mounted on the other side (e.g., the underside) of the wipe interaction end of the spring mounted assembly. The springmounted assembly has an opening at the wipe interaction end of the spring -mounted assembly, which may be configured to allow the partially or fully wet roller to partially pass through the opening of the spring-mounted assembly. The opening may substantially cover the width of the spring-mounted assembly. The partially or fully wet roller may be configured to pass through the spring-mounted assembly when the spring -mounted assembly is depressed by some force. When minimal external forces are applied to the spring -mounted assembly, the spring mounted assembly is configured such that dispersible wipe material is held away from the partially wet roller at the wipe interaction end of the spring-mounted assembly. During dispensing, a force is applied to spring -mounted assembly, forcing the assembly to pivot around its axis of rotation 942, and forcing the partially wet roller to partially pass through the opening. The force may be applied through the dispersible wipe material, for example if the dispersible wipe section is pulled across the assembly. The dispersible wipe material is therefore forced into contact with the partially wet roller, wetting the wipe material.

Figure 9A shows the apparatus during a stationary or pre-dispensing mode. At the start of dispensing, dry dispersible wipe material 922 is conveyed or pulled across the assembly (e.g., downwards), as shown by arrow 900A. Figure 9B shows the result of this action, wherein spring -mounted assembly has been depressed and dispersible wipe material is now in contact with and being wetted by the partially wet roller. Arrows 900B and 900D show the movement of the dispersible wipe material across the partially or fully wet roller and arrow 900C shows the rotation of the partially or fully wet roller. Figure 9C additionally shows a pipe configured to convey the at least one liquid for wetting the wipes 908 and a roll of dispersible wipe material 926.

Reference is now made to Figures 10A and 10B which show aspects of the means for dispensing and means for wetting according to some embodiments of the invention. Both Figures 10A and 10B show a first roller 1020 and a second roller 1048, each with a substantially circular cross-section. The rollers are configured to dispense the dispersible wipes between them by rotating in opposite directions. The pair of rollers form part of the means for dispensing. Arrows 1000A and 1000B and arrows 1000C and 1000D show the direction of rotation of the rollers during dispensing.

Both Figures 10A and 10B also show a separate means for wetting the dispersible wipe material, wherein the means for wetting is connected to at least one pipe 1008 configured to convey the at least one liquid from its at least one container to the means for wetting. The means for wetting may comprise at least one liquid sprayer 1050, configured to create a liquid spray 1052 configured to wet the dry dispersible wipe material 1022. Additionally or alternatively, the means for wetting may comprise at least one liquid tap or dispenser 1054, configured to drop liquid 1056 onto the dry dispersible wipe material 1022. There may in some embodiments be only one sprayer or tap configured to wet the dispersible wipe material, or there may be more than one sprayer or tap, each configured to wet different sections of the dispersible wipe material, in order to wet the full width of the dispersible wipe material.

Reference is now made to Figures 11A and 1 IB which show aspects of the means for dispensing and means for wetting according to some embodiments of the invention. Both Figures 11 A and 1 IB show a first roller 1120 and a second roller 1148, each with a substantially circular cross-section. The rollers are configured to dispense the dispersible wipes between them by rotating in opposite directions. The pair of rollers form part of the means for dispensing. Arrows 1100A and 1100B show the direction of rotation of the rollers during dispensing.

Figures 11A and 11B additionally show a means for wetting, which comprises a container or trough below a portion of the dispersible wipe material 1158, wherein the container is configured to contain an amount of the at least one liquid for wetting 1162, and wherein the means for wetting additionally comprises an applicator brush 1160 configured to wet the wipe material 1122 with the liquid in the container (though not necessarily through contact of the brush with the wipe material). The brush may be, for example, a broadly cylindrical brush lying within the container, and configured to rotate around an axis of rotation lying through its centre. The bristles of the brush may point outwards from the cylindrical brush. The container may lie underneath a section of the dispersible wipe material and may lie along the whole width of the dispersible wipe material. The brush may lie along the majority of the length of the container. Wetting may be achieved by movement of the brush, for example wetting may be achieved by rapidly rotating a cylindrical brush within the container, such that the rapid rotation creates a spray of liquid which may wet a dry section of dispersible wipe material to result in wet dispersible wipe material 1124. Arrow 1100C shows an example of the rotation of a brush according to some embodiments. Figure 11 A may show the apparatus during a stationary mode and Figure 11B may show the apparatus in a dispensing mode.

Reference is now made to Figures 12A and 12B which show aspects of the means for dispensing and means for wetting according to some embodiments of the invention. Both Figures 12A and 12B show a first roller 1220 and a second roller 1248, each with a substantially circular cross-section. The rollers are configured to dispense the dispersible wipes between them by rotating in opposite directions. The pair of rollers form part of the means for dispensing. Arrows 1200A and 1200B show the direction of rotation of the rollers during dispensing. Figures 12A and 12B additionally show a means for wetting, which comprises a container or trough below a portion of the dispersible wipe material 1258, wherein the container is configured to contain an amount of the at least one liquid for wetting 1262, and wherein the means for wetting additionally comprises an applicator 1264. The applicator is configured to press a portion of dispersible wipe material into the liquid in the container during dispensing, such that wetted dispersible wipe material 1224 may pass through the rollers to be dispensed. Arrow 1200C shows the direction of movement of the applicator 1264 prior to or during dispensing. Figure 12A shows the apparatus in a stationary mode, whereas Figure 12B shows the apparatus in a dispensing and wetting mode, wherein the dispersible wipe material is conveyed through the liquid because of the movement of the applicator. The applicator may additionally be a roller.

Reference is now made to Figures 13 A, 13B, and 13C which show aspects of the means for dispensing and means for wetting according to some embodiments of the invention. Each of Figures 13A, 13B, and 13C show a first roller 1320 and a second roller 1348, each with a substantially circular crosssection. The rollers are configured to dispense the dispersible wipes between them by rotating in opposite directions. The pair of rollers form part of the means for dispensing.

Additionally shown is a partially or fully wet pad/sponge 1368, made of a similar material to a partially wet roller of other embodiments. The partially or fully wet pad/sponge is optionally contained in block container 1358, which advantageously may stop liquid leaking into the rest of the device. The partially or fully wet pad/sponge may lie close to the dispersible wipe material 1322. The partially or fully wet pad/sponge may lie across the full width of the dispersible wipe material. Additionally shown is a stamp block 1366. The stamp block may also lie close to the dispersible wipe material 1322 on the opposite side to the partially wet block. The stamp block is configured to be able to press a portion of the dispersible wipe material into the partially or fully wet pad/sponge in order to wet said portion.

Figure 13 A shows a stationary mode of the apparatus not during dispensing. Dispensing and wetting is shown in Figures 13B and 13C, wherein, unlike in some other embodiments, wetting is not concurrent with dispensing. Wetting is shown in Figure 13B. The arrow 1300A shows the direction of movement of the stamp block when the stamp block pushes the dispersible wipe material into the partially or fully wet pad/sponge. Dispensing is shown in Figure 13C. The arrow 1300B shows the stamp block moving away from the dispersible wipe material, which allows for movement of the wipe material. Arrows 1300C and 1300D show the rollers conveying and dispensing the wetted wipe material.

Reference is now made to Figures 14A and 14B which show aspects of the means for dispensing and means for wetting according to some embodiments of the invention. The apparatus comprises a first roller 1420. The apparatus further comprises a partially wet belt or conveyer belt 1470. The first roller 1420 and the partially wet belt operate to convey dispersible wipe material between them by rotating in opposite directions. The partially wet belt is additionally configured to provide a means for wetting the dispersible wipe material. The partially wet belt comprises a first section of its surface 1472 which is configured to provide the means for wetting the dispersible wipes with at least one liquid. The first section of its surface may be constructed from or made of similar materials to those used to construct the first section of the surface of the partially wet rollers of other embodiments. The partially wet belt additionally comprises a second section of its surface 1474, which is configured to provide a means for holding a section of the dispersible wipe material 1422 between itself and the first roller when not during dispensing. The belt may be in operable connection with at least two internal cogs or rollers 1476A and 1476B. One or more of these rollers or cogs may be attached to other aspects of the means for dispensing (e.g., a motor or gears).

Arrows 1400A and 1400B show the rotation/movement of the roller and belt during dispensing and wetting of the dispersible wipe material. Advantageously, the belt may be of a length, such that after a full movement (wherein a full movement may be defined as a movement where second section 1474 starts at the contact point with dispersible wipe and roller and travels the full length of belt to arrive at the same location) an ideal desired length of wipe has been dispensed. While a partially wet roller may achieve the same result by being made larger or smaller, a partially wet belt may achieve the effect with substantial space and material savings. The belt may also have a greater curvature at the contact point with dispersible wipe and roller, when compared to a roller, which may reduce the possibility of accidental wetting and dispersing of the dispersible wipe. The belt may also be directed away from the path of wetted wipe section 1424.

The rollers of this or any other embodiment may be replaced with a belt (whether partially wet or otherwise). The partially wet belt of this embodiment may incorporate features of any partially wet roller of other embodiments. For example, the second section of the partially wet belt 1474 may protrude from the surface of the partially wet belt, and/or the second section 1474 may have a blade mounted thereon (discussed later). Suitable adjustments may be made to the rest of the features of Figures 14A and 14B to account for these incorporations.

The device of any previous embodiment may additionally comprise a means for cutting dispersible wipes. Cutting may take place before, during, or after dispensing and wetting. A means for cutting may be advantageous to the function of the device but may not be necessary.

Reference is now made to Figures 15 A, 15B, and 15C which show aspects of the means for cutting according to some embodiments of the invention. Figures 15A-15C show a cutting apparatus 1578, with a blade 1580 mounted across the width of a section of dispersible wipes 1522 (wet or dry). The blade may be mounted for rotation around a hinge at one end 1584. The blade may be supported by a spring mechanism 1582 at the other end. During cutting, the blade may be pushed into and through the dispersible wipe material, thus cutting the material. The spring mechanism may subsequently force the blade into an open position, to again allow wipe material to pass the blade. The blade may be curved to allow optimal cutting. Arrow 1500A illustrates the cutting motion of the blade.

Reference is now made to Figures 16 A, 16B, and 16C which show aspects of the means for cutting according to some embodiments of the invention. Figures 16A-16C show a cutting apparatus 1678, with a blade 1686. The blade is mounted to a movable mount 1688A, which is contained within or mounted upon rail 1690. The rail is mounted across the width of a section of dispersible wipes 1622 (wet or dry). During cutting, the mount 1688B is configured to move within/upon the rail, thus moving the blade through the dispersible wipe material, and cutting it.

Reference is now made to Figures 17A and 17B, which show apparatus 1700 which shows aspects of the means for dispensing, wetting, and cutting according to some embodiments of the invention. Apparatus 1700 comprises a first roller 1720 and a second roller 1714, wherein the second roller is a partially wet roller. The partially wet roller may be constructed according to other embodiments of the invention. The partially wet roller comprises a first section of its surface 1716 which is configured to wet dispersible wipes in contact with this section. The partially wet roller additionally comprises at least one second section of its surface 1718 which is configured to hold a section of the dispersible wipe section between itself and the first roller 1720 when not during dispensing. According to embodiment 1700, the at least one second section 1718 has mounted thereon at least one blade 1790. First roller 1720 optionally also has at least one cavity 1792 configured to receive the at least one blade during rotation of the rollers. The blade 1790 may be of substantially the same length as the roller and may be mounted lengthways along its surface. It may be advantageous, though not necessary, that the circumference of the second (partially wet) roller is divisible by the circumference of the first roller. This may allow for a reduced number of cavities 1792 in the first roller, since the location of intersection with the blade may be easily predicted.

Arrows 1700A and 1700B show the rotation of the rollers during dispensing. Dry dispersible wipe material 1722 is conveyed/dispensed between the two rollers, and wetted, to provide wetted dispersible wipe material 1724 A. When the second surface of the partially wet roller meets/contacts the dispersible wipe section, the blade mounted thereon cuts the dispersible wipe material, separating that which has been wetted from that which has not yet been wetted. The wetted section is thus of the form of a separate retrievable wet wipe 1724B. A blade may also be implemented in a similar way on the second section of the partially wet belt of Figures 14A and 14B, advantageously giving more freedom over the length of cut pieces of dispersible wipe.

Reference is now made to Figure 18, which shows apparatus 1800 which displays aspects of the means for wetting and storing dispersible wipe material according to some embodiments of the invention. Apparatus 1800 contains liquid containers 1806A and 1806B configured for storing liquid suitable to wet the dispersible wipes. The contained therein may be conveyed through pipes 18O8A and 18O8B to a liquid mixer 1894. Liquid mixer may be configured to mix the liquids together at a certain ratio and then convey the mixed liquid into at least another pipe 18O8C and 18O8D. Pipe 18O8C and/or 18O8D may be connected to a means for wetting the dispersible wipes. In some embodiments, wipes 1826 may be mounted for rotation on roller 1828 underneath the liquid tanks to make efficient use of space.

There is also provided, in accordance with an embodiment of the invention, a method for simultaneously dispensing and wetting dispersible wipes, the method comprising: dispensing the dispersible wipes from a repository for storing dispersible wipes in a dry form; and during or immediately before the dispensing, wetting the dispersible wipes with at least one liquid suitable to wet the dispersible wipes from at least one container. According to some embodiments of the invention, the method additionally comprises cutting the dispersible wipes during or immediately before the dispensing.

The above method(s) may utilise the device and dispersible wipes of any of the embodiments of this invention.
