Abstract
A fluid dispenser comprising a dispensing mechanism, a housing and a container having an interior. The container is removably coupled to the housing for dispensing fluid from the container by the dispensing mechanism. The housing has a guard recess opening downwardly and an access opening into the recess. A piercing member is secured in the recess. The container has a protuberance which is adapted to be received in the recess such that when the container is being coupled to the housing, the protuberance on the container is inserted upwardly into the recess and moved into the piercing member to pierce the protuberance with the piercing member. On the piercing member piercing the container, an air passageway is provided providing communication between the interior of the container and the atmospheric air. Preferably the piercing member is secured in the guarded recess against engagement other than with elements inserted into the recess via the access opening.
