<p>PURPOSE:To easily, certainly open a package where a container for a disk cassette, etc., is wrapped with an exterior packaging film having a cut-tape on the inner face and the overlapping part is heat-sealed, by providing a step larger than the width and thickness of the cut tape at a position on the container corresponding to the end of the cut tape. CONSTITUTION:A step 10 is provided at a position on a container 1 corresponding to an end 9a of a cut tape 9 attached on the inner face of an exterior packaging film 7. The step 10 is wider and deeper than the width and thickness of the cut tape 9. Thereby, when the container 1 is wrapped with the exterior packaging film 7 and the overlapping part is heat-sealed, the container 1 is enveloped with the exterior packaging film 7 with the end 9a of the cut tape 9 facing the step 10. Therefore, the pressure of a heater during heat sealing can be released by the step 10, preventing the end 9a of the cut tape 9 from being bonded.</p> |
