Packs of self opening plastic bags and method of fabricating the same

For seriatim dispensing from a rack, said rack comprising:

• a pair of parallel rods spaced from each other by a first predetermined distance, said rods being secured to project normally to a vertical plane and lying in a transverse horizontal plane;
• said rack further being provided with an element disposed equidistantly between said rods and projecting upwardly to a height below said horizontal plane;
• a pack of coinciding pressed together T-shirt type plastic bags for dispensing from said rack when mounted thereon;
• each of said bags being formed of a pair of abutting polyethylene front and rear sheets of a rectangular configuration, said sheets being sealed to each other along their sides and bottom edges and having a pair of handles spaced from each other by a distance in excess of said first predetermined distance and formed by a cut-out extending downwardly and inwardly of the side edges a second predetermined distance from the central portion of the upper edges of the sheet, said handles being sealed across their upper edges, the central area of the lower edge defining the cut-out of each sheet also defining an upwardly projecting tab, said tab comprising an upper expanded portion connected to the lower edge of the cut-out by a narrower neck portion;
• each of said handles being orificed at a predetermined point so that all of the orifices of the handles of the bags of the pack are in register, the predetermined points in the handles of each bag being spaced apart from each other by said first predetermined distance, the expanded portions of the tabs of each sheet having an inner transverse slot, and the neck portion of each said tab being slit transversely between, but not extending to, the neck edges, the neck of the tab of the rear sheet of the first bag of the bag pack being lightly adhesively adhered to the neck of the forward sheet of the next ensuing bag of the pack at a point adjacent to, but below, the slits in the tab necks;
• whereby, when said pack of bags is mounted on said rack by passing the rods through the handle orifices, and the upwardly projecting element through slots in the expanded portions of the tabs, as each bag on the pack is pulled off the rods, its tabs are restrained by the upwardly projecting element, to detach at their necks at the ends of their transverse slits, and the neck of the tab of the rear sheet, by virtue of its slight adhesion to the neck of the tab of the front sheet of the next ensuing bag, initially pulls the bottom cut-out edge of the next ensuing bag to open the bag until, and, with the force developed by further pulling the first bag off the rack, said adhered necks then pull apart from each other at the point where they are lightly adhered, to result in the removal of the first bag into which articles may have been placed, and the presentation of the next ensuing bag in open condition to receive additional articles.
