ABSTRACT:
A container in which a recess for containing a coiled spring is formed at a shaft hole opening in a cover and a container. A connecting portion for connecting the other end of the coiled spring is formed at the other of the cover and the body in such a manner that the connecting portion is substantially oppositely formed to the recess at the shaft hole opening. A connecting piece capable of temporarily connecting the other end of the coiled spring is formed, and a packing elastically contacted with the lower surface of the cover of closed state is associated intimately with the upper end of the bottomed cylindrical container body. Thus, the container can by simply produced by readily associating the cover and the container body and can also assure the sealability between the cover and the body.
