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.
