<P>PROBLEM TO BE SOLVED: To ensure and improve the convenience of a container in a variety of aspects ranging from content filling to cleaning of the empty container. <P>SOLUTION: The container comprises a container body, a closure cap fitted on the spout of the container, a discharge tube penetrating the cap, a pinch valve, which is arranged in the middle of the tube and has an automatic closing mechanism having an energy applying means that pinches the tube in a normal state to keep it closed, and an opening mechanism which opens the closed tube. The container is further provided with a lever, which has a normal state return means independent from the energy applying means of the automatic closing mechanism, or returns to the normal state by self-elasticity. When an external force is applied to the lever to operate it, the lever acts on the opening mechanism to open the discharge tube. When the external force is removed from the lever, the closing mechanism and the lever return to their normal state separately. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
