<p>PROBLEM TO BE SOLVED: To provide a container sealing strip for preventing contents from coming out or being exposed with a lid opened, wherein in particular the sealing strip is of such a novel structure that it is formed into a cylindrical strip from a plane sealing sheet and easy to manually handle. SOLUTION: Main pasting margins C at both ends of a sealing strip sheet are overlaid in layers to be welded or glued, thereby forming a welded or glued portion. In addition, one or more auxiliary welded portions or auxiliary glued portions are formed in a margin widthαfrom an inner rim of the welded portion or the glued portion inside the welded portions or the glued portions and at positions to be an appropriate portion deep from openings of both ends when the sheet is formed into a cylindrical strip, thereby providing the container sealing strip.</p> |
