Description:

FIELD OF INVENTION

The invention pertains to plastic grocery, produce and merchandise bags. More particularly, the invention relates to T-shirt style and other handle bags manufactured in registered stacks for dispensing from racks having twin central support arms. The bags are dispensed without leaving a torn remnant of the bag 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. Instead of apertures through the bag handles, the present invention incorporates a pair of apertures through a central portion of the bag adjacent the bag mouth. A variant of the invention is an open mouth bag without t-shirt style handles. Rather, the bag has a pair of handle openings in the upper region of the bag walls below the bag mouth and apertures for the pair of central supporting rods. Both bags may be removed from their supporting racks without leaving any torn bag remnants on the rack. Various designs for such “remnant free” systems have been developed.

U.S. Pat. No. 5,188,235, issued to Pierce et al., discloses a bag formed of multiple stacked handle bags having aligned mounting apertures defined through the handle portions of the bags for reception of mounting rods therethrough. The mounting apertures are formed as elongated, generally vertically extending, slots having curved upper and lower portions. Elongated mounting slots make possible the use of shorter handles for the bags without sacrificing either the size of the mouth opening during loading or the carrying capacity of the bags. A central mounting tab on the multiple stacked bags has a vertical perforation extending between a generally horizontal central mounting aperture and the bag mouth, thus permitting the bag to be removed from a cooperating bag rack without leaving any portion of the central mounting tab on the bag rack.

U.S. Pat. No. 4,676,378, issued to Baxley et al., is directed to bag pack formed of multiple stacked handle bags having aligned mounting apertures defined through the handles thereof for reception of mounting rods therethrough. The apertures are formed by partially severed flaps which are bonded together to maintain aperture alignment. The flaps are integral with the bags along minor easily severed areas for a freeing of the bags upon a severance of the flaps simultaneous with or subsequent to reception of the mounting rods through the apertures.

U.S. Pat. No. 5,464,098, issued to Tseng et al., discloses method for manufacturing automatic consecutively opened thermoplastic T-shirt bags for dispensing from a conventional supporting rack. The method involves providing a continuous flattened tube of thermoplastic film and applying adhesive solution using a printing press to form adhesion regions on the outside of the tube. The adhesive solution can be applied using a flexo or gravure printing process.

The method then involves forming side gussets in the tube and making traverse seals in the tube, thereby dividing the tube into pillowcases. The pillowcases are separated at the seals to form a series of end-sealed gusseted pillowcases which are stacked to form a bag pack. Next, the bag pack is cut along a bag-mouth contour to from a plurality of T-shirt bags. The bag-mouth contour forms a set of laterally spaced handles each having a receiving aperture for a conventional support rod of a dispensing rack, a central tab having a mounting aperture, and an open mouth region. The adhesion regions are optimally located below the receiving apertures and above the lowest point of the bag-mouth contour. Finally, slight pressure is applied to the proximate area of the adhesion regions of each bag in the bag pack to form a disengageable link between consecutive bags. The invention also relates to the T-shirt bags and the bag packs produced from this method.

U.S. Pat. No. 4,480,750, issued to Dancy, is directed to a thermoplastic bag having front and rear walls with smooth upper edges defining an open bag mouth. A pair of laterally spaced integral loop handles extends upward from the bag mouth and include detachable mounting tabs projecting laterally inward from the handles at an intermediate point along the height thereof. The tabs are remote from the bag mouth and, in a bag pack, form the securing area for the bags.

U.S. Pat. No. 4,785,938, issued to Benoit, Jr. et al. 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.

It is an objective of the present invention to provide a T-shirt style and other handled grocery or merchandise bag that will not leave any remnant of the bag on a dispensing rack. It is a further objective to provide such bags that can be easily and reliably manufactured and that can be stored in registered alignment for ease in placing into a dispensing rack. It is a still further objective of the invention to provide a bag stack that includes weakened areas at the hanging apertures permitting the areas to rupture at a point below the top of the bag mouth. Finally, it is an objective to provide bags incorporating self-opening features.

While some of the objectives of the present invention are disclosed in the prior art, none of the inventions found include all of the requirements identified.

SUMMARY OF THE INVENTION

The present invention addresses all of the deficiencies of prior art tabless T-shirt style and open mouth bag pack inventions and satisfies all of the objectives described above.

(1) A twin support aperture side-tear bag pack providing the desired features may be constructed from the following components. A plurality of registered polyethylene bags is provided. Each of the bags has front and rear walls joined at their substantially parallel first and second side edges. The front and rear walls are joined at their substantially parallel upper and lower edges. The front and rear walls have a U-shaped cut-out commencing at a first point on the upper edge spaced inwardly from the first side edge, extending downwardly toward the lower edge and returning upwardly to a second point on the upper edge spaced inwardly from the second side edge. The U-shaped cut-out forms an open bag mouth, a pair of bag handles and at least one front or rear central tab extending upwardly from a central point on the bag mouth.

The central tab has a top edge, first and second lateral edges extending downwardly from the top edge. The central tab is penetrated by first and second support apertures for suspending the bag pack on support arms of a dispensing rack, the apertures are located below the top edge. The central tab has a weakened area between each of the first and second apertures and one of the first and second lateral edges. When one of the bags is pulled from the dispensing rack, the weakened areas of the central tab will rupture, thereby causing the central tab to remain with the dispensed bag.
