<p>The specification discloses the combination of a bottle and a connecting cap therefor, both components having mating screw threads, the components having a mating key and keyway system extending axially of the bottle neck and being designed so that mating of the key and keyway system is necessary before relative rotation between the cap and the bottle to screw the cap onto the bottle is possible. Thus, a connecting cap can only be secured to a bottle if the bottle and cap are complementary and the potential danger of connecting a bottle containing the wrong liquid to, for example, an anaesthetic vapouriser, can be avoided.</p> |
