Abstract
A cap with valve has a fluid flowing hole formed within a cylindrical cap body installed in an aperture of a container. A valve body is installed within the cap body and has a seal lip opened in an umbrella-like shape which is inserted in the fluid flowing hole and pressed against the periphery of the fluid flowing hole at the rear side in the inserting direction so as to close the fluid flowing hole. The valve body is held by a support plate having rigidity installed within the cap body, and is urged by a biasing means installed within the cap body for urging the support plate so that the valve body is inserted in the fluid flowing hole. A stopper is formed on the support plate and abuts on the cap body and restricts moving of the valve body so that the valve body together with the support plate is prevented from being subjected to pressure beyond a prescribed value to move it further in the inserting direction towards the fluid flowing hole.
