The cover includes a body having a plane surface defined at an upper end thereof and which is connected to a flap defined at a lower end of the body for sealingly engaging the mouth of the container. A semi-spherical shaped expansion chamber is positioned between and connecting the plane surface and the flap, and an inner trunk-conic wall abuts the plane surface and extends way from the plane surface and toward the mouth of the container. The inner trunk-conic wall terminates at a bottom wall, wherein the bottom wall extends transverse relative to a longitudinal axis of the cover; and an exhaust hole is defined in the bottom wall.
