PROBLEM TO BE SOLVED: To enable a sealingly closed lid to be easily removed by a method wherein an adhering tape covering an entire opening seal line composed of parallel punched-out lines arranged along an extending axis of the lid is adhered from a front side. SOLUTION: In case that a lid 1 closely closed against a main body 1 of a container is removed, at first a non-adhering section 6a acting as a guiding piece is held and then a seal 6 is peeled off toward a center of it. Then, a first tongue 4 defined by the opening seal line 3 is lifted up together with the seal 6 under a state in which it is being adhered to the seal 6. Then, as the seal 6 is pulled up toward the center of the lid 1 as it is, material quality of the lid 1 is of a double-axis extending film, resulting in that the lid 1 is broken wide at its center to generate an opening seal port. Then, the remaining second tongue 5 is held with fingers and pulled toward a circumferential edge as it is and then the tongue is broken together with its circumferential edge. As a result, the lid 1 is widely broken from the circumferential edge together with the central section and it may easily be removed. |
