ABSTRACT:
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 is a seal piercing means which pierces a diaphragm in or adjacent the tap inlet and which after initial operation of the push button remains lodged in the pierced diaphragm, the piercing means only being moved by the push button on the initial operation. The arrangement ensures an 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.
