PURPOSE: To manufacture a container by adding only to a closing part at the time of sealing the container by sealing the container by using a heat fusion bondable material, and injecting the material on the container at the time of thermoforming or sealing the container. CONSTITUTION: A heat fusion bondable material for sealing the container is injected on the container or particularly on an edge of the container. This operation is conducted to form one or a plurality of continuous closing lines along a peripheral edge of the container. This releasable part is decided according to a selection of a bead material, the container for supporting the bead to the bead or cover. For example, as a general example, in the case that a surface of the container is a polyolefin, the material can be selected mainly from a polyethylene, polypropylene or a copolymer of these materials and a vinyl scetate or the like. A shape of the bead 6 is selected to cut fibers by an operation of scissors with sufficient amount of the material. A section of the bead can be made substantially rectangular, triangular or circular. |
