Abstract

The present invention is directed to an end stop (134) for a thermoplastic bag (120) having a reclos-able fastener (121) at the open top end of the bag. The reclosable fastener (121) comprises a pair of interlocking fastening strips (130, 131). The end stop (134) is config-ured to facilitate snap fit insertion onto the fastener strips (130, 131) and includes a top portion and a pair of de-pending side portions (172, 174) that straddle the fastener (121). The side portions (172, 174) further include in-wardly directed tab and shoulder structure (198, 202) that engage the reclosable fastener and prevent the end stop from being inadvertently pulled off in a transverse direc-tion in order to hold the end stop in place prior to being bonded to the bag. The bonding step is preferably accom-plished by ultrasonic welding. In the case of the line pro-duction of thermoplastic bags wherein a continuous web of plastic material is moved from one station to the next, the invention allows for the positioning of the end stop onto the reclosable fastener at a first station and the bond-ing of the end stop to the bag at a second station. The positioning and bonding steps may be performed simul-taneously.
