Abstract

A container includes a base, a cover and an intermediate part. The base includes a first room and a first lip extends from the open top of the base. The cover includes a second room and a second lip extends from the open bottom of the cover. The intermediate part includes a third room and a third lip extends from the open top of the third room. The cover is mounted to the base with the intermediate part located between the cover and the base. The cover seals the base and the intermediate part by one-time pressing action. The base includes at least one plate which is engaged with a recess formed to the outside of the second lip of the cover to secure the cover to the base.
