EASILY UNSEALABLE CONTAINER

摘要

[PROBLEMS] A container having a blister-shaped containing section for covering an article can be easily unsealed and can be unsealed without damaging base paper. [MEANS FOR SOLVING PROBLEMS] The container has a containing section (11) for covering an article, a cover member (13) having a flange (12) projecting outward along an opening edge that surrounds the containing section (11), and base paper (14) to which the cover member (13) is fixed at its flange (12). With one surface of the flange (12) made to be in contact with the front surface of the base paper (14), a flange fixation member (15) is bonded along the direction of the flange (12) to both the other surface of the flange (12) and that portion of the front surface of the base paper (14) which surrounds the other surface of the flange (12), and thus the cover member (13) is attached to the base paper (14). In the above described boding of the flange fixation member (15), the flange fixation member (15) of a thermoplastic film is heat sealed. To facilitate separation of the bonded flange fixation member (15) from the flange section (12), the fixation member (15) is adapted such that the direction of the separation agrees with the direction of the flange (12), the separation progresses in the minimum width of the flange fixation member (15) perpendicular to the direction of the separation, and the separation requires minimum force. The flange fixation member (15) has a projection (17) projecting from the portion where the flange fixation member (15) is bonded to the base paper (14), and the flange fixation member (15) functions as a portion to be held by fingers.
