Klemmförmige Endstoppteile für wiederverschliessbare Verschlüsse aus Kunststoff.

摘要

A fastener structure for a thermoplastic bag, comprising a pair of flexible plastic strips (14,15) adapted to be secured to the facing sidewalls along the mouth of a thermoplastic bag; reclosable interlocking male and female profile elements on the respective strips; and a slider (10) straddling the strips for opening or closing the male and female profile elements. The structure also includes end clamp means (30) located at the opposite ends of said strips (14,15), each of said end clamp means (30) comprising a pair of clamp members positioned, in use, on opposite sides of the bag for clamping the pair of strips and the facing sidewalls of the bag therebetween. Means (30a,30b) is provided for clamping each of said pair of clamp members together to provide a seal at the ends of said strips, said end clamp means providing a stop surface adapted to engage with the slider for preventing the slider from moving past the ends of the strips. A method of manufacturing a plurality of thermoplastic bags incorporating a fastener structure is also disclosed.
