PROBLEM TO BE SOLVED: To provide a standing pouch container capable of accurately measuring and extracting content.SOLUTION: Only by water head pressure of a filling space 16, content does not pass through a check valve 21 nor moves to a measuring space 20. Further, when pressure is acted to side films 11, 12 by fingers, the content passes through the check valve 21 and moves from the filling space 16 to the measuring space 20 in accordance with pressure and an action time. Whether a prescribed amount is stored in the measuring space 20 is confirmed in reference with a scale 32, and when the content reaches a predetermined amount, pressure action is stopped. Once the content is stored in the measurement space 20, the content is not returned to the filling space 16 by the check valve 21. A cap 18 is opened, a standing pouch container is tilted and the content is extracted. The content stored in the measurement space 20 is extracted. On the other hand, if pressure is not made to act to the filling space 16, the content in the filling space 16 is not moved to the measuring space 20, nor is extracted. Thus, only measured content can surely be extracted. |
