Reclosable stand-up bag for packaging fluids - has flexible foils and reclosable screw closure

摘要

When the bag is flat and empty one of the two foils is folded down at the top end of the bag. The inner face of this foil is turned out so as not to contact the inside face of the other foil in this area. The inside faces of the two foils exposed by the fold of one foil are covered by a top sheet and welded to same along the edge. The reusable screw closure is welded by its flanged edge to the top sheet. The corners of the two foils are removed at least one of the two upper ends of the bag. The two foils each end in a top edge, which includes a trapeze shaped surface which when the bag is flat and empty is folded down. ADVANTAGE - The bag is easy to open without scissors, can be resealed fluid tight after partial emptying and subsequently allows complete emptying of the contents.
