  • Patent number: 6098806
    Abstract: A pack of merchandise bags is provided in a closed storage and dispensing unit. A portion of the unit is removable to provide a window through which the bag pack is exposed. Each bag in the pack is provided with a front and rear tab at the top, with the rear tab of a bag being attached to the front tab of the next bag. In addition, the rear tabs are formed together in a stack which is secured inside the unit, and each rear tab is attached to its respective bag through a relatively weak perforation. Thus, when a bag is withdrawn from the back pack by means of the front tab, the bag is opened, because the rear tab is retained to the stack of tabs. However, as additional force is exerted on the bag, the rear tab is torn free at the perforation. Since this rear tab is attached to the front tab of the next bag, the next bag is automatically opened.

  • Patent number: 6079877
    Abstract: A plastic T-shirt bag pack in which the outer walls of adjacent bags have been corona-treated and each bag is provided with a central rack mounting tab with a pair of angled lines coming together in an apex adjacent the upper edge of the central tab, the lines being readily severable when the tab is placed on the central mounting element of a conventional rack. At their opposite ends the lines are curled inwardly toward each other to prevent their tearing from propagating down into the bag walls. This may be further prevented by providing a sinusoidal cut below the lower extremities of the angled lines. The area between the apex and upper edge of the tab is provided with a tear start so that when the bag is pulled from the rack, the area is severed to permit removal of the tab with the bag. Appropriately disposed pressure points with the corona treatment above, enable the bags of the pack to be self-opening.

  • Patent number: 6068128
    Abstract: A bottom-seal bag for wickets comprises wicket holes positioned outside an interior side gusset fold when the bag is in a lay-flat condition. The wicket hoes pass through the back panel and side gussets, and in some embodiments, the front panel. Front cut lines in the front panel and front gusset portion reduce the separation force of the front panel of the bag from the wicket as compared to the back panel of the bag. The front cut lines are positioned outside the interior side gusset fold in a lay-flat condition. The cut lines may be continuous or non-continuous. The cut lines allow the front panel and front gusset portions of the bag to be easily separated from the wicket with a low pulling force to reduce operator fatigue and improve reliability of bag filling and separation operations. Additional pulling force separates the back panel and back gusset portion from the wicket, completely releasing the bag.

  • Patent number: 5996801
    Abstract: The invention encompasses a system by which a leading T-shirt bag may be removed from a rack while initiating the opening of the bag mouth of the next ensuing T-shirt bag, but without also simultaneously pulling out and opening in succession subsequent T-shirt bags of the pack. The invention accomplishes this by modifying the form of the conventional T-shirt bag by placing a second lower slightly offset horizontal tear slot below the horizontal slot on the center mounting tab by which the tab is held on the hook of the dispensing rack. The offset slot creates a narrow bridge on one end and a wider bridge on the other end of the slot. A glue spot is provided offset from the center toward the side with the narrower bridge, between the back of the forward bag and the front of the subsequent bag. When the leading T-shirt bag is filled and subsequently pulled away, the wider bridge first ruptures and the narrower bridge, coupled with the offset glue spot, works to pull open only the next bag.
