A tap operated by a push button which acts to open a valve member which is biassed to the closed position, the valve member being for normal operation of the tap; also operated by the push button, but only on initial operation of the push button, is a plugging means which plugs the inlet of the tap and which after the initial operation remains out of the inlet. The arrangement ensures added protection against oxygen penetrating into a container fitted with the tap and is particularly useful for wine containers where the added protection ensures a longer shelf life. The use of a plugging means fitted tap avoids the necessity of special sealing equipment for the containers in the winery where containers are filled.

A tap comprising a valve casing that includes a duct opening at one end at a fluid outlet and at the other end at a fluid inlet, a valve for normal open and close operation of said tap, said valve comprising a seat, and a valve member seating on said seat, said valve controlling fluid flow out said outlet during normal operation of said tap, a push button connected to said valve for manually opening said valve, said valve being normally biased closed until and unless said push button is pressed against said closure bias, a plug slidably mounted in said duct, said plug being movable from an initial plugging position interiorly of said duct where fluid flow through said tap is prevented to a normal operating position where fluid flow through said tap is permitted as controlled solely by said valve, and abutment means operably interconnected with said plug and with said push button, said valve member being movable along a motion axis oriented at an angle of about 90°to the motion axis of said plug, initial operation of said push button to open said tap causing said abutment means to move said plug from said initial plugging position to said normal operating position, said plug thereafter remaining in said normal operating position during subsequent operation of said push button so that said plug slides only on initial pressing of said push button against said normal valve bias and does not slide upon subsequent open and close operation of said valve by subsequent pressing of said push button.
