容器用ポンプ装置。[Claims for Utility Model Registration] A piston 3 is disposed in the cylinder 2 so as to be able to slide vertically. A seal 3b and a lower seal 3c are provided, and when the piston 3 is in the upper position, an air hole 2 communicating with the inside of the container is located between the upper seal 3b and the lower seal 3c on the wall surface of the cylinder 2.
In a container pump device in which the upper seal 3b passes through the air hole 2a as the piston 3 moves up and down, the long axis of the air hole 2a corresponds to the sliding direction of the piston 3. A pump device for a container, characterized in that the holes are elongated in the same direction.
