<p>A fit-holding groove is formed by notching the outer periphery of a door element (13) to be fitted to close a container body (1). A sealing element (20) interposed between the container body (1) and door element (13) is composed of an endless portion to be fitted into the fit-holding groove (16), a protruding part projected (22) from the peripheral corner of the endless portion, obliquely and outwardly with respect to the open front of the container body (1), forming a substantially acute angle between itself and the contact surface of the open front of the container body (1) and a pair of fitting ribs (23) projectively formed on the obverse surface of the endless portion (20) so as to be fitted in contact with the compartmentalized inner wall of the fit-holding portion. <IMAGE></p> |
