Abstract
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.
