摘要

The barrel (1) is for the transport of liquid, particularly beer, having a tapping bush (5) inserted in its body (2). The opening is sealed off by a non-return valve at the inner end of the bush. At the outer end of the bush is a protective cap (8). It, or a component attaching it to the body, is destroyed or damaged on removal. It can contain fracture points where the material is thinner. It can have a circular base portion enclosed by a peripheral wall, on the outside of which are locking lugs engaging in recesses in the bush. The recesses can be combined together into an annular groove. USE/ADVANTAGE - Barrel tapping system whereby the user can easily see it the barrel has already been tapped.
