    摘要： The present invention provides a cap capable of improving sealing performance of a container, and suited for use in the case where the internal pressure of the container is high, for example, when the contents of the container is carbonated beverage, and a container having the cap.
    The present invention includes a cap main body having a top wall and a skirt wall pending from an outer circumferential part of the top wall, the skirt wall being provided with an internal thread that comes in screw engagement with an external thread of a container mouth part, and a gasket made of synthetic resin for hermetically sealing the container mouth part,
    wherein the gasket has a top plate that comes in abutment with a distal end part of the container mouth part to cover the distal end part, and an annular inner leg pending from the top plate, adapted to close fit with an inner circumferential face of the container mouth part, and an outer circumferential edge of the top plate is continuously formed with an annular bent part that bends downward with respect to the top plate and has the inner circumferential face covering an outer circumferential face of the container mouth part, and
    the cap main body has a biasing part that biases an outer circumferential face of the bent part of the gasket in a closed state, so that the biased bent part elastically deforms to be pushed against the outer circumferential face of the container mouth part.
