Abstract
A carbonated beverage package comprising a container having an opening with a peripheral lip defining a free edge, and a downwardly and outwardly inclined sealing surface spaced from the free edge of the peripheral lip. A closure of plastic material, such that it will flex in thin cross section, is provided with an annular wall, a radial wall engaging the free edge of the peripheral lip of the container, and a transverse wall defining a convex surface facing inwardly of the container. The closure has a downwardly and outwardly inclined integral annular sealing surface at the juncture of the axial wall and transverse wall which engages the sealing surface of said container and places the axial wall under tension. The closure has a pressure relief rib at the juncture of the radial wall and axial wall such that axial force in the area overlying the rib will move a portion of the annular sealing surface of said closure away from the sealing surface of said container so that the pressure in the container can be relieved through a pressure relief opening through to the atmosphere and the closure can therafter be readily removed from the container.
