disposal and means to withdraw liquids from containers to lose with recovery of the withdrawal device

摘要

The container comprises a plastics casing 2, e.g. of polyethylene, which may be contained in a substantially rigid cardboard casing 1. A tap 3 comprises a hollow stem 5 terminating in a conical end 4. An aperture in the cardboard casing 1 acts as tap-guiding means and may be reinforced by a disc 10. The tap 3 is inserted through the aperture to pierce the plastics casing 2. When the casing 2 is empty, the tap 3 may be withdrawn for re-use. The cardboard casing may be omitted and tap-guiding means provided by a collar formed from two disc portions (12, 13 Fig. 4) interconnected by a hollow cylinder portion (11). IMAGE
