<p>PROBLEM TO BE SOLVED: To make the positioning of seal grooves easier when they are fitted to each other at a portion where an upper lid is joined to an outer case main body, and improve workability. SOLUTION: This stoning container is constituted in such a manner that a portion between an outer case main body 3 containing an inner case which contains plate-like members and an upper lid 4 covering an upper part of the outer case main body 3 to be joined thereto is maintained in a state that the upper lid 4 is pressed against the outer case main body 3 by a locking means, and also that a seal member 6 disposed in a seal groove 5 formed throughtout the entire periphery of the joint so that respective openings are opposed to each other is compressed on an opposed face of the other seal groove 18 for which the seal member 6 is fitted to an outer side of the seal groove 18 so as to cover it, and is kept in a sealed state. In this instance, the seal grooves 5, 18 are formed into a cross-sectional U-shape so that the respective openings are opposed to each other, and a guide 21 having an inclined cross section, which is projected from the top 18a of a side wall and expands from the inner side of the seal groove 18 toward the outer side thereof, is provided to the other seal groove 18 to be fitted to the outer side of the seal groove 5 to which the seal member 6 is disposed.</p> |
