A two stage dispensing cap for a carbonated beverage container is described. The cap has a flip top which is hingedly connected to a collar wherein the collar is rotatable on the container. The cap, upon rotation of the collar, is first opened into a venting position wherein the flip top vents the pressurized contents of the container but remains locked partially closed. Continued rotation of the cap releases the locked flop top to allow the container to be fully opened. A set of cams on the container neck work in conjunction with annular beads to first allow partially opening of the flip top into the venting position and then allowing it to fully open. |
