ENDSTOP AND DOCKING MEANS FOR THERMOPLASTIC BAGS

摘要

In a thermoplastic bag having a reclosable fastener (11) extending along the mouth of the bag and a slider (10) straddling the fastener for opening and closing the fastener, the fastener including two opposing interlocking fastener strips (14, 15) along the side walls (12, 13) of the bag, the slide r adapted to maintain straddling relation with the fastener, an improved endst op means (30) proximate to at least one end of the reclosable fastener, the endstop means being formed from the material of the fastener strips and risi ng vertically from the fastener to a height adequate to engage the slider 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 thereof, the rail extending to a point sufficient to permit the slider to cooperate with the rail to maintain straddling relation with the fastener wh en the slider reaches the endstop. Docking means (40) and methods of making endstop means and docking means are also disclosed.
