  • Patent number: 5626550
    Abstract: A bag pack comprises a plurality of easy open handle bags. The bags are easy to open because the exterior surfaces of the bags are cold-welded together so that when one bag is pulled from the pack, the adjacent next bag is at least partly open. The external surfaces of the bags are not welded to the internal surfaces of the bags during the pressure welding process, because the material that forms the external surface of the bag is treated with a corona discharge, which renders the external surface more susceptible to cold weldings. Optionally a static charge is induced on the bags so that each bag is at a different voltage than the adjacent bags so the bags attract each other, and the panels of each individual bag repel each other, to contribute to the easy open feature.

  • Patent number: 5507713
    Abstract: A system for suspending a pack of thermoplastic bags, loading bags, removing loaded bags and for automatically opening the next bag preparatory to loading it by having a pack of handled bags suspended from laterally spaced elongated rods of a rack. The bags have been corona discharge treated to such an extent that the application of pressure will cause adjacently facing regions to releasably adhere together until a moderate force separates them. During removal of a bag from the bag pack at least a portion of the front wall of the next bag will follow the bag being removed for a short distance before separation thereby opening said next bag rendering it ready for loading. An improved means for applying the requisite pressure is disclosed herein.

  • Patent number: 5382215
    Abstract: A process for producing paper bags with handles glued to the insides of the facing opening edges, includes perforating a paper web with transverse perforation lines spaced at distances corresponding to the section lengths necessary to produce the bags. At a given distance from the transverse perforation lines the handles are glued in adjacent pairs to the web in such a way that the outer handle parts project beyond the transverse perforation lines. The web is joined together into a tubular web by folding over its side edges, such that the handles face each other. The overlapping side edges that have been folded together are glued to form a seam. The sections are detached along the transverse perforation lines and each section is provided with a bottom portion at the end opposite the handles.

  • Patent number: 5378220
    Abstract: A reusable yard waste container has a four sided rectangular shell which is open at its top end and has a flat multi-layered bottom. Two opposed sides of the shell have medial fold lines which allow the container to be collapsed to a flat orientation where it can be folded into a small package for storage. Located on the sides normal to the folding sides are upper and lower handles which facilitate handling of the container when full and erecting it from its collapsed orientation. Pockets at the bottom of the container receive weights to prevent the container from blowing away when it is left after being emptied. Snaps permit the top of the container to be closed when it is full. The container is constructed by placing four inwardly facing folds in the side walls of an elongate hollow cylindrical shell to form a rectangular cross-section shell with two pair of opposed sides.
