<P>PROBLEM TO BE SOLVED: To provide a valve inner stopper, which has a simple structure and seals up a container certainly after being used without an operation by a user. <P>SOLUTION: The valve inner stopper 1 comprises an inner stopper body 3 and a valve 2. The inner stopper body 3 has an outflow hole 11, from the inner peripheral surface of which an elastic deformation part 5 and a valve seat 8 are formed, respectively, and the valve 2 is arranged to be pressed between the elastic deformation part 5 and the valve seat 8. When a content is discharged, inner pressure applied to a container makes the valve 2 push up the elastic deformation part 5, while moving away from the valve seat 8, to form a gap 10, through which the content is sent and discharged from through holes 7 on the elastic deformation part 5 to the outside. When the inner pressure is released after using the container, an elastic force of the elstic deformation part 5 returns the valve 2 to the original position, where the valve 2 presses the valve seat 8 to seal up the container. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
