FORMATION OF OPENING CAPABLE OF EASILY UNSEALING PACKAGING FILM CONTAINER WITH ZIPPER (SLIDE FASTENER)

摘要

PROBLEM TO BE SOLVED: To enable two packaging films to be formed automatically into a short one and a long one from a zipper when a packaging film container is unsealed with scissors or hands by an existing technology with no complicated processes or working.;SOLUTION: When a container is unsealed with scissors or hands, separating a zipper that is the open/close opening has been difficult because of the overlap of the cut openings of two packaging films almost of the same shape. This invention is a technology which enables the cut openings from the zipper to be formed automatically into a shorter one and a longer one to facilitate the opening and closing of the zipper when a container is unsealed with scissors or hands by an existing technology.;COPYRIGHT: (C)2015,JPO&INPIT
