Claims

[Scope of Claim for Utility Model Registration] (1) An elongated cylindrical pressure can whose lower end face is a concave surface protruding inside the can, has a valve on its upper end face, and stores a liquid in the internal space, and the interior of the pressure can The internal pressure generating means
A flexible pressurizing bag that is inflatable to pressurize the liquid until it fills the can, and the liquid can be taken out in required amounts by opening the valve for a certain period of time. A pressure canner for supplying a liquid agent, characterized in that a communication member is provided on the inner surface of the cylindrical part of the pressure canner over a certain width from the lower end to the upper end, and has a flow path that communicates with the entire length in the longitudinal direction. Pressurized can. (2) The liquid agent supply device according to claim 1, wherein the cross-sectional shape of the communication member has one surface having a radius of curvature approximately equal to the inner diameter of the pressure can, and a groove on one or both surfaces. Pressurized can. (3) The pressurized can for liquid supply according to claim 1, wherein the connecting member is made of an elastic material.
