Abstract

A t-shirt style grocery or merchandise bag pack includes a plurality of plastic bags, each having a pair of bag handles and a central tab located above the bag mouth. The bag pack is suspended from a dispensing rack by openings through the bag handles and a hanging aperture located in the central tab. The tab is designed to rupture at the hanging aperture when the bag is dispensed from the rack. The tab may have a flattened top and a pair of opposed lateral sides or it may have a rounded top. The weakened area may take the form of a cut or a notch. These weakened areas may begin at the hanging aperture or one of the lateral sides of the flattened top tab or at a point below the top most point of the rounded tab. The weakened area may also be perforation or a single opening.

Description

    FIELD OF INVENTION
  • The invention pertains to plastic grocery, produce and merchandise bags. More particularly, the invention relates to T-shirt style handle bags manufactured in registered stacks for dispensing from racks. The bags are dispensed without leaving a torn tab portion on the dispenser.
  • BACKGROUND OF THE INVENTION
  • T-shirt style bags were developed to provide a strong, low-cost, high capacity bag for groceries or merchandise that incorporates strong, integral handles. This is accomplished by creating a gusseted polyethylene tube, sealing it at both ends and cutting out a “mouth section.” The result is a bag that includes a pair of strong handles formed from the side gussets and the bag's upper seam. While such bags are very useful for transporting heavy loads, they can be difficult to load as they lack the means to stand upright while empty, as does a square-bottomed paper bag.
  • For this reason, racks have been developed to hold and dispense registered packs of t-shirt style bags. In order to be dispensable from such racks, the bag packs typically have a pair of apertures through the bag handles to fit on side arms of the dispenser and a central tab. The central tab includes an opening or slit designed to fit over a hook or protrusion at the center of the dispenser. Early designs for T-shirt bag packs included a central tab designed to be torn from the bag upon dispensing. Such systems, while effective, required periodic removal of the torn off tabs from the dispensing rack. More modern designs, known as tables T-shirt bags, have incorporated a weakened area or perforation line connecting the aperture or slit used for suspending the bag pack from the dispenser's hook, to the top edge of the tab. Thus, when the bag is pulled from the dispensing rack, the weakened area will break and the tab will remain with the bag. Various designs for such tables systems have been developed.
  • U.S. Pat. No. 5,979,655, issued to Tseng et al., discloses a plastic bag stack with special tab opening. A tab is mounted on the central retainer of a conventional rack. A slot or opening is provided by means of a cut comprising a transverse base line that extends part way between the side edges of the projection or tab and terminates at each end in an upwardly and backwardly extending curve respectively. The curve extends as a very short segment and then continues as a reverse curve upwardly toward the upper edge of the tab leaving a small tear space between the curve terminus and upper edge. Any force applied at the opening of the tab will rupture the area, thereby permitting removal of the tab from the rack retainer element with the remainder of the bag.
  • U.S. Pat. No. 6,446,810, issued to Huang et al., is directed to a tabless self-opening bag pack. The tab portion has a curved aperture slit that is used to suspend the pack of bags on a rack. Each curved aperture slit has a main cut section that is substantially parallel with the bottom edges, a first curved cut section coupled to one end of the main cut section, and a second curved cut section coupled to an opposite end of the main cut section.

  • U.S. Pat. No. 5,881,882, issued to Fletcher et al., discloses a plastic bag pack adapted to leave no residue on a supporting rack. The bags include a detaching central tab having an aperture for mounting the tabs on a tab retaining device of the rack. Each of the bags of the pack further includes a means to propagate a controlled tear from the tab mounting aperture to the open mouth for detaching the tab from the rack tab retaining device. This tear propagating means is in the form of a V-shaped cut-out formed in and extending downwardly from the top of the central tab and a nick formed at the apex of the V-shaped cut-out and extending downwardly there from toward the tab mounting aperture. When stresses are placed on the detaching central tab, the stresses are concentrated by the V-shaped cut-out into the nick to propagate a tear down through the wall of the detaching central tab to the aperture.
  • U.S. Pat. No. 5,346,310, issued to Nguyen, is directed to a thermoplastic bag system. The bag has a mouth from which emanates a tab. Situated at an angled, lateral position relative to the upper edge of the bulbous portion of tab is the tab support slit having first and second ends. The tab is shown in more detail and includes a slit having first and second ends, the first end being formed near the first bulbous tab extension and running generally toward the first, short neck edge, then generally leveling horizontally in the medial area of said slit, then running downward along path and curving back towards generally the first bulbous tab extension before terminating in an end. The user applies light pressure to the face of the tab and the slit ruptures at its higher, first end, tearing to the outer edge of the tab at rupture zone, releasing the tab from the rack.
  • U.S. Pat. No. 6,269,950, issued to Nguyen discloses a tab-free thermoplastic T-shirt bag system. Emanating from the bag mouth is a raised area with a support cut having first and second ends. Relative to the support cut is a laterally situated dispense cut having first and second ends. The application of light pressure to a medial edge of the support cut causes a rupture at the space between the edge and the second, bottom tip of the dispense cut, the rupture communicating with the dispense cut, releasing the bag from the support tab.
