<P>PROBLEM TO BE SOLVED: To solve the problems that an opening is not readily detached and a content is scattered due to a shock of detachment and sometimes contaminates hands since the opening is detached by holing a pull tab by a finger in a conventional opening structure. <P>SOLUTION: A tab having a projection is rotatably provided, and an opening formed with an outline having a thin thickness is provided on the top plate of a container. The pull tab is raised and rotated. The projection provided on the pull tab is made to abut and pressed against the opening, thereby breaking the thin groove forming the opening. In this process, the scattering of the content is prevented by the pull tab itself. <P>COPYRIGHT: (C)2010,JPO&INPIT |
