Abstract
The invention relates to a container assembly of a container containing a flowable substance; a container holding assembly attached to the container which comprises an opening mechanism for selectively opening the container and being adapted to move from a closed position to an open position of the container and vice versa, and a locking mechanism for holding the opening means in a closed position of the container. The locking mechanism is intended to be released by the release member of a reservoir assembly arranged so that release is effected when the container holding assembly is held in a stable delivery position on a reservoir. The invention also relates to the combination of such a container assembly and a reservoir assembly specially adapted for receiving the container assembly.
