ABSTRACT:
A container cap is disclosed. It has a cap body and a push button member vertically slidably fitted within the cap body. The cap body is integrally formed with a cylindrical wall for engagement with a neck portion of a container, and the push button is integrally provided with a plurality of leg pieces. A plurality of lever pieces are connected at one end thereof to the leg portions and at the other end to the cap body through hinge means, respectively. The intermediate portions of the lever pieces are abutted against a supporting point of the container, whereby the lever members are, upon downward movement of the push button, rotated around the supporting point to thereby push the cap body upward while releasing engagement between the neck portion and the cylindrical wall.
