Title:
【発明の名称】シート又はウェブで形成された包装積層材に把持装置を連結する方法
Document Type and Number:
Japanese Patent JP2674848
Kind Code:
B2
Abstract:
In the manufacture of single-use disposable packages or cartons for, for example, milk or juice, a web or sheet-formed packaging laminate is normally reformed by folding and sealing processes into individual packages. The material may possibly also be caused to pass through a bath of chemical sterilization agent. As a result of the forming and sterilization processes, it is impossible to provide the material beforehand with applied opening arrangements such as plastic pull-rings or the like. A method of connecting a gripping device to a sheet or web-formed packaging laminate includes the steps of providing the laminate with a non-penetrative hole or recess (6) in which an anchorage device (7) of thermoplastic material is created by injection moulding. The anchorage device does not affect the inner layers (3, 4, 5) of the laminate and consequently creates a reliable and tight anchorage for a gripping device (12) which is applied after reforming of the laminate into the package.
