Appeal No. 1999-1080
Application No. 08/681,022
Favre's invention relates to:
[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).

Moore's invention relates to a dual chamber pump
dispenser “for lotions, creams and the like.” See col. 2, l.
53. Moore teaches that
. . . earlier pump dispensers were often constructed
with a single chamber, and an upper piston connected
to the actuator cooperated with a lower, independent
