PROBLEM TO BE SOLVED: To prevent a liquid material in a suction pipe from being discharged by a method wherein a spring on-off valve having a stopper to close a liquid spout port in the bottom of a measuring cap is supported on a cylindrical part that is continuously formed from the liquid spout port. SOLUTION: When a container main body 1 is pressed in the middle, a content A rises from the bottom of a pipe 10 and enters a cylindrical part 9 after passing through an opening of a support ring 20 that is a component of a spring on-off valve 22. Then, when the content A passes along a spring 19, it pushes a stopper 18 up using the elastic property of the spring 19 to form a gap between the stopper 18 and a liquid spout port 8 provided in a bottom 7. The content A flows into a measuring chamber 3 through the gap, and when a specified amount of the content A is fed and pressing of the container main body is stopped, the stopper 18 seals up the liquid spout port 8 by the elastic force of the springs 19, with the specified amount of the content A left in the measuring chamber 3. Thereby, only the content A in the measuring chamber 3 can be discharged outside. |
