ABSTRACT:
Packs of T-shirt type plastic shopping bags are fabricated in such a manner that when the bags are mounted on conventional racks, as each bag is pulled off the rack, the front wall of the next ensuing bag is pulled out to open the bag for the depositing of articles to be packed in the bag. This is accomplished by providing a special configuration for the central tab which is hooked on the upwardly extending element in the rack. The tab has a narrow neck which is partially slit between the neck edges and is adhered to the tabs of adjacent bags by an adhesive spot applied in hot melt condition below the slit. Thus, pulling of the rear wall of each bag first effects a rupture of the tab neck of the rear wall of the bag at the tab slit, while simultaneously rupturing the neck of the tab of the front wall of the next ensuing bag and pulling said front wall away from the rear wall of the latter bag, until, with further pulling, the adhered spots on the neck of the rear wall of the bag being pulled and on the neck of the front wall of the next ensuing bag, detach from each other. Such adherence is accomplished in the course of production of bag packs by a gun discharging a hot melt adhesive.
