A cap with a valve is provided with a valve mechanism for generating negative pressure, the valve mechanism comprising: a valve body that is fitted and held in a fitting hole in a top plate portion formed in an upper part of the cap main body; A valve plate is disposed via a spring on a spring holding plate held in the main body, and the valve body has a flow passage hole in the upper part and a tapered umbrella part in the lower part that spreads downward. The valve plate has an annular seal lip protruding from the inner circumferential surface of the umbrella, and the outer circumferential surface of the valve plate is substantially parallel to the inner circumferential surface of the umbrella and normally abuts the seal lip. A cap with a valve characterized in that a substantially hemispherical protrusion is formed as a sealing surface.
