Beer barrel - with inner metal or plastic bag and outer plastic injection moulded shell

摘要

A container, esp. a beer barrel is made at least partly of plastic material. It consists of an inner container designed as a thin-walled metal or plastic bag for the liq., on which the outer shell has been injection moulded from plastic material. The outer shell can also be made of two halves, welded by a peripheral seam. The bag is fixed to an oval metal plate with the taphole. ADVANTAGE - This simplifies the mfr. and reduces the costs for it.
