Abstract: A dispensing tap of the type which is attached to a cask or a bottle is described. The tap body having an inlet and an outlet and a valve element controlling the outlet. A small bore capillary tube is attached to the inlet of the tap and a sleeve surrounds the junction between the small bore capillary tube and the tap body and pass the length of the small bore capillary tube. The valve element and body are formed with cooperating screw threads so arranged that rotation of the valve element causes movement thereof relative to the outlet to open or close the outlet. A releasable locking means is provided for preventing rotation of the valve element.

Abstract: A tap made of plastic material for dispensing liquids from containers comprising a body having a cylindrical sleeve portion for attachment to a container from which liquid is to be dispensed, the wall of the cylindrical portion being provided with an outlet hole, a tap member having a hollow cylindrical spigot portion, the outer surface of which fits tightly into the sleeve, while being free to rotate therein, the spigot having an outlet hole which can be brought into and out from, alignment with the outlet hole in the sleeve by turning the spigot and a removable plug to close the open outer end of the hollow cylindrical spigot. Removal of the plug enables the container to which the tap is fitted to be filled through the tap spigot, the spigot being maintained within the sleeve with a tight fit to retain an effective seal.

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, 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.

Abstract: A tap comprising a tubular body open at one end and closed at the other end by a flexible resilient diaphragm. The diaphragm is connected to a valve element arranged to close a valve seat at said one end of the body. The body of the tap is made of a material of lower permeability than that of the diaphragm, and the diaphragm is closed to the atmosphere by a cap or a coating. The edge of the valve element is flush with said one end of the body.

Abstract: A pouring device for use with a container, the device having a central liquid outlet and air inlets positioned annularly around the outlet so that whatever the axial alignment of the device when fitted to the container there is always an air inlet above the outlet; the device has a flared pouring lip which extends to a planar annular lip; preferably a bung is provided to close the outlet and inlets which may be attached to the lip of the device by means of a break away ring provided on the planar portion of the lip of the device.
