PROBLEM TO BE SOLVED: To improve the response at the time of starting the jet of a container jet button and the sharp stoppage without dripping at the time of completing the jet and prevent the solidification and deformation of quality of a content after the completion of jet operation. SOLUTION: A jet button is provided with a valve member 17 biassed in the left direction by a spring 18 so as to block a jet opening 15a, and the jet opening 15a is opened by the jet operation of pushing down a cap 10 toward a button main body section 11 by the length (a) to move the valve member 17 in the right direction in resistance to the spring 18 (the state represented by the figure.). At that time, a content in a container is passed through a vertical hole passage 12 and a horizontal hole passage 14 of the button main body section 11 and jetted out of the jet opening 15a. When the jet operation is completed, the button main body section 11 is biassed upward and the valve member 17 is moved again in the left direction by the elastic force of the spring 18, and the jet opening 15a is blocked tight by the end 17a of the valve member. |
