とを特徴とする弁付キヤツプ。 A top plate with a flow passage hole is formed at the top of the synthetic resin cap body with a cylindrical wall that is attached to the opening of the container, and a top plate with flow passage holes is provided at the bottom of the top plate. When the pressure decreases, the fluid can flow into the container from outside the container through the flow path hole, and the flow path hole can be closed by abutting against the periphery of the flow path hole through a normal biasing means. In the cap with a valve, in which a valve body for negative pressure is disposed, a substantially tapered umbrella-shaped cylindrical part is formed in the top plate part, expanding downward from the periphery of the flow passage hole and having an inner circumferential surface serving as a sealing surface. ,
Furthermore, an umbrella part that is substantially parallel to the seal surface and bends diagonally downward is protruded from the valve body, and the outer peripheral surface of the umbrella part has an annular seal lip that normally comes into contact with the seal surface at the periphery of the flow passage hole. A cap with a valve characterized by a protruding portion.
