Abstract: A tie bag includes a hem seal, at the mouth of the bag, which grips the top of a receptacle, when the tie bag is used as a liner for the receptacle, to preclude having the mouth of the bag fall into the receptacle. The hem seal forms a hem flap, which is cut in a geometric pattern to provide tie fasteners. The hem seal may also form a hem at the open mouth of the tie bag. The tie bag may further include a pair of secondary hem seals closing the hem at the opposing sides of the sidewalls.

Abstract: A container (120) includes a closure device (121). The closure device includes interlocking fastening strips (130, 131) and a slider (132) slidably disposed on the fastening strips for facilitating the occlusion and deocclusion of the fastening strips. The slider includes first and second side portions (140, 142) and a top portion (144). The first side portion (140) includes pivot arms (158, 168). The pivot arms (158, 168) include shoulders (156, 166). The second side portion (142) includes pivot arms (152, 162). The pivot arms (152, 162) include shoulders (150, 160). The pivot arms (152, 158, 162, 168) create a pivot point for the shoulders (150, 156, 160, 166) that prevents the slider (132) from being removed from the fastening strips in the vertical Z axis (106). The shoulders move into the fastening strips when an upward force (180) is applied in the Z axis (106).

The slider (132) includes a top portion (140) and first and second side portions (142, 144). The slider additionally includes shoulders that merge into the first and second side portions and prevent the slider from being disengaged from the fastening strips. The slider includes long length front shoulders (150, 156) and long length rear shoulders (162, 164) in conjunction with shorter length front shoulders (152, 154) and shorter length rear shoulders (160, 166). If an upward force (180) is applied to the slider (132), the longer length shoulders are designed to remain engaged with the fastening strips when the side portions of the slider are forced to flex outward.

Abstract: The present invention is directed to an end stop for a thermoplastic bag having a reclosable fastener at the open top end of the bag. The end stop is configured to facilitate snap fit insertion onto the fastener strips. The end stop further include inwardly directed tab and shoulder structure that engage the reclosable fastener and prevent the end stop from being inadvertently pulled off in a transverse direction in order to hold the end stop in place prior to being bonded to the bag. In the case of the line production 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 bonding of the end stop to the bag at a second station.

Abstract: A closure device for a slider bag with a slider and an end stop operable to releasably latch the slider in the closed position and release the slider with minimal user applied force. The closure device includes first and second interlocking fastening strips arranged to be interlocked over a predetermined length. The slider is slidably disposed on the interlocking fastening strips for facilitating the occlusion and deocclusion of the fastening strips when moved towards first and second ends of the fastening strips. The first and second ends of the fastening strips are secured together and an end stop is provided to the first, closing end of the fastening strips. The end stop is provided with quick release latching structure engagable with cooperating latch-receiving structure provided to the mating or opening end of the slider to secure the slider when it is moved into engagement with the end stop at the closing end of the bag.
