Endstop and reclosable means for thermoplastic bags

摘要

A thermoplastic bag has a reclosable fastener (11) extending along the mouth of the bag. The fastener (11) includes two opposing interlocking fastener strips (14, 15) along the side walls (12, 13) of the bag, a slider (10) straddling the fastener (11) and an endstop means (30) proximate to at least one end of the reclosable fastener (11). The endstop is formed from the material of the fastener strips (14,15) and rises vertically from the fastener (11) to a height adequate to engage the slider (10) and prevent movement of the slider past the end of the bag. A rail (25) extends along the length of at least one of the fastener strips on the outside extending to a point sufficient to permit the slider (10) to cooperate with the rail (25) to maintain a straddling relationship with the fastener (11) when the slider (10) reaches the endstop.
