EASILY UNSEALABLE SEALING CONTAINER

摘要

A sealing container capable of reliably and easily unsealed and satisfying contradictory requirements of perfectness of sealing and easiness of unsealing. In the sealing container in which a sealing film (15) is adhered to the upper surface of a flange (12) surrounding the opening of a plastic packaging container (11), a breaking section (19) having a separation line and a connection section is formed at the flange, which enables the entire part or a part of the flange to be separated into an inner section (13) and an outer section (14). Further, a film for separation having a separation start section (21) is adhered to the lower surface of the flange where the breaking section is formed, and this makes it possible that the breaking section is exposed by separating the film along the flange. Adhesion force of the sealing film to that part of the flange which is outside the breaking section is set greater than adhesion force of the sealing film and separating film that adhere to the upper surface and the lower surface of the flange.
