<p>An aim of the invention is to provide a simple and effective one-piece tap which can be readily and economically manufactured. A tap for a liquid container is made from natural or synthetic rubber or a resilient plastics material. It has a base portion 10 having an orifice 12 which serves as a liquid inlet therein, the base portion embodying a liquid exit means 14. It also has a resilient deformable closure portion 20, the closure portion being constructed to make a resilient snap-on connection with the periphery of the base portion, the closure portion being manipulatable and having a centrally located plug 22 extending towards the base portion. This plug can obturate orifice 12 thereby closing the liquid inlet. The closure portion 20 also has a projecting portion 23 extending generally perpendicularly away from the base portion, the projecting portion being constructed so that it can be pushed towards the base portion in order to remove the plug from the orifice and so permit liquid to pass to the liquid exit means 14. <IMAGE></p> |
