Abstract

A closure of synthetic resin material has a cap connected to a base which fits onto the container by a hinge joint which may be of the flexible film type and can be molded unitarily with the base and cap. On the opposite side of the cap from the hinge, there is provided a lever which has a pressing plate and a hook, the latter being engageable with a detent on the base so that entered pressure on the plate allows the cap to swing upwardly.
