Container including a pressure relief valve for use in holding and dispensing soft drink material

An improved container for use in holding and dispensing soft drink syrup or pre-mix material, the container of a type which includes a cylindrical body having top and bottom surfaces, and wherein the body further includes an interior surface and an exterior surface, and wherein the interior surface of the body defines a cavity within which the material may be held, the body defining an opening which is selectively occluded by an oval lid and further defining two ports in the top surface which individually extend between the interior surface and the exterior surface, and wherein one of the two ports has been previously used for withdrawing the material and the other of the two ports has been used previously for introducing carbon dioxide into the container, the improvement comprising:

• (a) a valve which is installed within the opening, the valve being operable to simultaneously dispense the material and introduce a source of gas to the cavity, and Wherein the oval lid is removed prior to the installation of the valve;
• and
• (b) a pressure relief valve which is installed in at least one of the ports, and wherein the other port is sealed, and wherein the pressure relief valve is normally closed and the pressure relief valve opens when pressure in the cavity exceeds a pre-selected amount.
