<P>PROBLEM TO BE SOLVED: To provide a lid closing implement which is easily attached to/detached from a liquid material storing container and has a high retention force corresponding to a state accompanied by an atmospheric pressure variation, and to refrigeration/freezing storage or the like, and to provide the liquid material storing container. <P>SOLUTION: The lid closing implement for the liquid material storing container includes a base, a closing part and a hook part, and closes an opening of the storage container provided with a collar extended to the lateral side from the upper end part of a storage cylinder. The hook part includes a lateral side member extended downward from the base, a collar-retaining pawl extended to the closure part side from the lateral side member and a collar-abutment surface being a side surface of the lateral side member. The base, the collar-retaining pawl and the lateral side member form a substantial channel letter on the side surface vertical to the collar-contacting surface. When the inserted lid closing implement is rotated in one direction, the collar intrudes into a gap between the collar-retaining pawl and the base, the side surface of the collar is abutted on the collar-contacting surface which is located in the proceeding direction of the collar side surface, the rotation of the lid closing implement with respect to the storage container is stopped and, by rotating the lid closing implement in the direction reverse to the one direction from the position where the rotation of the lid closing implement is stopped, the lid closing implement is detached. <P>COPYRIGHT: (C)2012,JPO&INPIT |
