Abstract: Casks for liquids such as fruit juices or wine use air impervious bags to contain the liquid so as to increase its shelf life considerably. However, the material of the dispensing tap allows oxygen to penetrate thus reducing the shelf life. To overcome this it is proposed to use an oxygen impervious diaphragm at the inner end of the dispensing tap. It is therefore necessary to include in the tap a device for rupturing the diaphragm without interfering with the operation of the tap. This is done by including in the apparatus a body, a probe mounted within the body, and a handle. An initiator is provided to move the probe during or prior to the first operation of the apparatus to move the probe axially inwardly so as to rupture the diaphragm.

Abstract: A tap for a "bag-in-the-box" containers which includes a body having a cylindrical wall extending interiorily and exteriorily of the container, the cylindrical wall having a beveled end across which a diaphragm is mounted, a spigot having a cylindrical wall part rotatably mounted within the body cylindrical wall portion and also having a beveled end whereby rotation of the spigot within the body removes the diaphragm and brings openings in the body and spigot into alignment for beverage discharge.

Abstract: A tap for "bag-in-the-box" containers, the tap having a body and a spigot, the inner end of the body being sealed with the spigot puncturing or removing the seal upon the first operation of the tap.

Abstract: A dispenser tap has a body, a handle, and a probe mounted within the body. The probe is hollow and has a pointed inner end with openings allowing liquid to be dispensed. The body has a spigot-receiving part which has a bore passing through it and a seal at one end thereof. The probe has radially outwardly extending pins that fit into corresponding slots in the body. In use, turning the handle cammingly moves the probe to an extended non-return position such that the seal is pierced and rupturned. The pins within the slots prevent the probe from rotating during this operation.
