<P>PROBLEM TO BE SOLVED: To provide an easily peelable opening structure for a container by which an abnormal peeling and the deformation of an opening section accompanying the abnormal peeling can be prevented from occurring, and in addition, which is advantageous in both of the simplification of manufacturing processes, and the reduction of costs. <P>SOLUTION: This opening structure for the container is constituted by closing an opening section which is provided at a predetermined section of a container main body for discharging and/or injecting a content is closed by an easily peelable seal means. The opening structure for the container consists of a three piece structure of the container main body having the opening section, an internal surface film, and a pull-tab. The opening section and the surroundings are closed by the internal surface film which covers the end surface of the opening section from the internal side of the container, and the pull-tab which covers from the outside of the container. At the same time, a non-bonded section having a predetermined width is provided at least on the peripheral edge of the external surface of the opening section from the opening edge end surface. Then, the opening structure is constituted in such a manner that the internal surface film, the opening section peripheral edge and the pull-tab are bonded across the opening section. <P>COPYRIGHT: (C)2007,JPO&INPIT |
