Abstract
A double dispenser for fluid products, comprising, in a single casing (1), two chambers (2) filled with different fluids and each closed by a pump (3) provided with a valve, the two valves being actuated by a single pusher (5). The pusher (5) has a chamber into which open the outlets of the two valves. This chamber is divided by a wall (7) so as to form two separate chambers (6', 6') into which open respectively the outputs of the two valves. The wall (7) has two outlet openings (8', 8') respectively connected to the separate chambers (6', 6'). These outlet openings (8', 8') open into cavities (10', 10') of a dispensing nose (11) of elastically deformable material. The dispensing nose (11) has an outlet slot (12) sealingly closed by two lips (13) arranged to spread under the pressure of the mixed fluid arriving respectively in the cavities (10', 10') during depression of the pusher (5). The dispensing nose (11) comprises an intermediate partition (14) separating the cavities (10', 10'). This intermediate partition (14) is made of a single piece with the dispensing nose (11).
