<p>A coupling/dispenser head for pressurized casks for liquids the said head being of inverted shell like form, with a resilient liner therein. The liner serves to blank off the gas pressure introduced through the head from the cask until the cask is broached by moving a lever carried by the head to move down a hollow plunger in the head, this action depressing the cask seal ring and distorting the liner so that gas pressure is applied into the cask and liquid can pass out through the plunger.</p> |
