Patent

CA 1335727

A dispensing device of the hand-held pump type has an internal piston which is pulled up by a rod passing through the piston, which rod is moved by an actuator. When the contents of the piston are emptied, in order to attach a refill, a dog release mechanism operates to release the dogs which, in normal use when the device is full, function to prevent the piston from being drawn downwardly so that the piston can be removed to allow attachment of the refill which has a new piston. This Abstract shall not be construed to limit the scope of the specification, drawings or claims.
