A fit-holding groove is formed by notching the outer periphery of a door element to be fitted to close a container body. A sealing element interposed between the container body and door element is composed of an endless portion to be fitted into the fit-holding groove, a protruding part projected from the peripheral corner of the endless portion, obliquely and outwardly with respect to the open front of the container body, forming a substantially acute angle between itself and the contact surface of the open front of the container body and a pair of fitting ribs projectively formed on the obverse surface of the endless portion so as to be fitted in contact with the compartmentalized inner wall of the fit-holding portion.

Sealing element with a protruding part approximately obliquely outward and a hermetic container using the same

In order to achieve constantly stable, high seal performance without requiring high machining accuracy, and in order to provide a reusable jacket seal, the present invention discloses a jacket seal, wherein a projection is formed at a position of a metal jacket in opposite relationship with a seal surface of a member being sealed, a flat portion is formed in an elastic member within the metal jacket so as to be brought into surface-to-surface contact with a flange portion interior surface, and the vertex portion of the projection is formed flat.
