ABSTRACT:
A closure of a liquid container, such as plastic bottles or chemical bottles, has a cap made of a resilient material and provided with a central opening-and-closing protrusion erected. By fitting a stopper of a relatively hard material onto the cap and provided with an engagement part onto the cap, the contents of the container can be poured and kept at its pouring or dispensing condition after the protrusion is rotated and engaged or hooked with the engagement part by a thumb and finger of the operator or user of the bottle. It is easy to release the hooked or engaged condition of the protrusion of the cap to the lever of the stopper, permitting the contents to be stopped from dispensing instantly.
