Abstract
There is disclosed a tubular connector for connecting the end of a tubular gas carrying conduit to the mouth of a thermoplastic bottle containing a liquid wherein the mouth prior to use has a breachable seal. The connector comprises two oppositely facing cup means each having internal threads therein, one to be screwed to the gas conduit the other to the mouth of the bottle. The two so disposed cups are connected by axially disposed tubular means extending respectively from each bottom of the cups whereby they are maintained in spaced relationship. That cup that is attached to a gas conduit is supplied with a relief valve at the bottom of the cup whereby excess gas pressure in the system is permitted to escape. At the same time a thin annular membrane is associated with the said relief valve whereby an audible sound is achieved due to the escaping gas.
