DESCRIPTION OF THE PRIOR ART It is known a soft container for transportation and storing of free-flowing bulk materials (RU 2132296 Cl, B65D 88/22,27. 06.1999).

The known container is made in the form of the vessel from synthetic material reinforced by strip load-bearing framework. The strip load-bearing framework is made in the form of load-bearing net sewed on the external surface of the vessel. The soft container is suspended from a crane hook by the loops formed by the extension of strip load-bearing framework. The loading opening of such soft container is very big and is equal to the vessel's diameter, which provides the ease of loading but doesn't allow providing the tightness of the upper part of the container.

The discharging opening due to the quick release joint between the vessel and the bottom provides the instantaneous discharging of load mass. But in this case it is not provided the discharging into the hatch of the ship, car or other vehicle. It is impossible to provide the sufficient tightness of the lower part of the soft container, which is important for a number of loads. Besides during the loading and discharging the dusting of the free-flowing bulk materials is not excluded which negatively affect the labor conditions and environmental ecology. The construction of known soft container reduces the ease of operation especially during the loading into the narrow hatches of vehicles or storage.

It is the object of the invention to increase the ease of the operation by the provision of the sealed loading from industrial pipelines or storage with simultaneous provision of required labor conditions and protection of the environment from pollution.

SUMMARY OF THE INVENTION This object is achieved by the soft container for transportation and storing of free-flowing bulk materials comprising a vessel with an upper loading opening and a lower discharging opening, a load-bearing net with lifting loops, a bottom and a tying down device including strip loops with a metal ring on one of the ends for the pinch, a stud for tying down and the locking strips for the protection against spontaneous untying, the vessel is disposed in the load-bearing net and is joined with it in the upper part by the demountable joint consisting of interconnected in series loops fastened to the vessel and the load-bearing net with the closure of the last loop group by the string tie. The extensions of the loops fastened to the vessel are made in the form of the strips inclined to the direction of the threads of the warp and of the weft of the vessel. In the load-bearing net it is made a bottom with an opening and a rim element aligning with the discharging opening of the vessel. The vessel is provided with the hoses with the strip loops for the pinch and the flap system. One of the hoses is fastened to the top of the loading opening for the provision of the loading process without the dusting of the free flowing bulk materials and the sealing of the upper part of the container during the transportation and storing. The other hose has a tying down device and is fastened to the lower discharging opening of the vessel enabling the setting of its outlet section during the discharging into the hatches of vehicles or storage and excluding the dusting of the free-flowing bulk materials, the flap system has a tying down device and is fastened to the rim element of the bottom opening of the load-bearing net for the fixing of the folded hose, fastened to the discharging opening of the vessel.

Such construction of the claimed soft container allows to hook up the hose fastened to the loading opening to the hopper (or to the industrial pipeline) with maximal convenience, in a short time and with the complete exclusion of the dusting during the loading; it allows to reliably close the hose by the strip loop for the pinch which provides the atmospheric moisture-tightness of the upper part of the soft container during the long-duration transportation or storage.

The construction of the (lower) hose fastened to the discharging opening, its geometrical construction, the system of the flaps and dying devices allow to set the hose immediately into the hatch of the railway wagon, the ship, the cistern or the storage, which provides the fast discharging of the soft container and excludes the dusting of free-flowing bulk products into the environment since during the transportation to the discharging place there are carried out the successive operations connected with the suspension of the soft container from the crane hook, the dying down of the flaps, holding the folded and tied down (lower) hose, then the setting of the hose into the hatch of the vehicle or the storage and only after that the untying of the pinched hose which causes the discharging of the soft container.

The soft container in the form of independent elements-the vessel and the load-bearing net, interconnected by the demountable joint consisting of closed in series groups of the loops belonging to the vessel and to the load-bearing net, allows to demount the soft container in a short time, to remove the damages and to mount the soft container in order to continue the operation, which allows to transform the throwaway container into the re- usable container replacing the element bearing only the single use with the new one.

The attachment (sewing on) of the strips which form the loops of the demountable joint to the fabric of the vessel with an inclination with respect to the direction of the threads of the warp and of the weft provides more uniform distribution of the load to the fabric of the vessel due to the loading of the threads of the warp and of the weft.

The attachment of the flap system to the pole collar in the bottom opening of the load- bearing net provides the convenience of the folding of the rolled (folded) hose and the fixing of the hose fastened to the discharging opening.

The vessel 1 is disposed in the load- bearing net 4 and is connected with it in the upper part by the demountable joint 9 consisting of interconnected in series loops 10 of the vessel 1 and loops 11 of the load- bearing net 4, the last group of the loops 10 and 11 being closed by the string tie 12. The loops 10 are formed by the strips 13 fastened to (sewn on) the fabric 14 of the vessel 1 obliquely to the direction of the threads of the warp and of the weft of the fabric. To the discharging opening of the vessel 1 there are fastened an (upper) hose 15 with an outlet end section 16 and a strip loop 17 (fig. 1) for the pinch. To the discharging opening of the vessel 1 it is fastened a. (lower) hose 18 with ah outlet end section 19 and a loop strip 20 for the pinch, which is tied down by a stud 21. To the rim element 8 of the opening of the load-bearing net bottom it is fastened a flap system 22 having a stud 23 for tying down the flaps. The hose 15 provides the loading without the dusting of the free-flowing bulk products and the sealing of the upper part of the soft container during the transportation and storing of the free-flowing bulk products. The hose 18 provides the setting of its outlet end section during the discharging into the hatches of vehicles or storage and excluding the dusting of the free-flowing bulk materials into the environment.

All the fabric elements of the vessel 1, of the reference numbers 15,16, 18,19 and of the flaps 22 are made from polyester, polyamide, polypropylene or other strong fabric, impregnated, rubberized or laminated by the suitable composition in order to give to the fabric the specified characteristics, for example, the chemical resistance, imperviousness to water etc.; all the strip elements of the load-bearing net 4, of the reference numbers 5, 8,9, 10,11, 13,17, 20 and of the flaps 22 are made from polyester, polyamide, polypropylene or other high-strong strips; the dying down studs 21 and 23 are made from steel or plastic.

The soft container for the transportation and storing of the free-flowing bulk materials works in the ordinary way: the loading, the transportation to the user, the discharging.

On fig. 4 it is shown a soft container the (upper) hose 15 of which has its end section 16 connected to the factory pipe-line. The vessel is filled with the free-flowing bulk materials by the upper hose 15.

The upper hose 15 of the filled soft container is pinched by the strip loop forming sufficiently tight container.

The filled soft container transported to the discharging place is suspended from a crane hook by the lifting loops under the hatch of the vehicle (fig. 5, 6). In this position the flap system 22 is tied down, the (upper discharging) hose 18 becomes free and is freely suspended under the hatch of the vehicle. The hose 18 is pinched by the strip loop 20 and is tied down by the stud 21. Then the soft container is lowered so that the outlet end section 19 of the hose 18 falls into the hatch of the vehicle, the stud 21 is untied, the strip loop 20 frees the pinched zone of the (discharging) hose 18 and the free-flowing bulk material flows from the soft container to the vehicle.

So the claimed invention is industrially applicable.

The realization of the invention provides: - the loading immediately from industrial pipe-lines and bins ; - the discharging into the narrow hatches of vehicles; - the tightness of the container in the areas of the upper (loading) and lower (discharging) openings ; - the increase in the resource and in the service life of the soft containers ; - the ease of replacement of damaged parts of the soft containers; - the increase in maintainability of the soft containers; - the ease of handling of the soft containers; - the exclusion of the environmental pollution by dusting of the free-flowing bulk materias during the loading and discharging.
