ABSTRACT:
There is provided a dispenser comprising a body for receipt of a carrier for a composition; an exit channel definable by the body for passage of the composition to a user; a cover for the exit channel reversibly movable between a storage position in which the cover fully protects the exit channel, to an in-use position wherein the exit channel is exposed. Biasing means act on the cover when the cover is not in the in-use or storage positions, to bias the cover towards either the in-use position or the storage position.
