ABSTRACT:
A carbonated beverage container having a cap which remains connected to the body of the container during the venting. Interlocking tabs are provided, two sets on the cap and one set on the container body, in a manner which allows the cap to be sufficiently opened to vent the internal pressure of the container. One set of tabs maintain the cap in a sealed relation with the container body while the second set of tabs prevents the cap further rotating during venting. Once the internal pressure has been sufficiently released, the second set of tabs can be disengaged and the cap removed from the container body. The cap is fully engaged and disengaged less than one full rotation of the cap relative to the container body.
