<p>The adaptors allow a number of containers to be joined together in a number of varied patterns, such as in-line, or in parallel or a combination of both. Each adaptor contains a stopper for the container. The stoper may take the form of an internal screw thread (i) which matches the thread on the container. The adaptors are in the form of cylinders which may be joined together by means of the screw threads. Alternatively the adaptors may be held together by a bayonet clip or a press fit.</p> |
