A mouth rinsing device comprising a pump housing and a reservoir. These two housings are arranged in series; i.e., the reservoir is attached to the base of the pump housing. A riser tube having a head on its end is situated on the pump housing and is fixed there by means of a lock so that only the head protrudes. When the reservoir is attached the lock is simultaneously released, so that the riser tube is able to slide into the reservoir and the intake opening is situated just above the base. After the reservoir is removed, the riser tube may be pushed in again manually. The riser tube is subsequently fixed in the retracted position by locking the head to the base of the pump housing.
