Patent ID: 8408201

Claim:
A fluid dispenser device including a body ( 10 ) that is provided with a dispenser orifice ( 1 ), said body ( 10 ) containing a plurality of reservoirs ( 21 ) formed on a common substrate formed by an elongate strip ( 20 ) that includes a leading end ( 25 ) and a trailing end ( 28 ), the device further including reservoir-opening means ( 30 ) that are adapted to open a respective reservoir each time the device is actuated, and drive means ( 40 ) for driving the elongate strip ( 20 ), so as to bring a full reservoir into register with said opening means before, during or after each actuation of the device, said device comprising at least one movable wall ( 500 ; 600 , 601 ) that separates, at least in part, a storage housing ( 11 ) for storing the elongate strip ( 20 ) from a reception housing ( 15 ) for receiving the elongate strip ( 20 ), said elongate strip ( 20 ) being disposed mainly in said storage housing ( 11 ) before the device is used for the first time, and being displaced progressively in said reception housing ( 15 ) each time the device is actuated, said at least one movable wall ( 500 ) causing the volume of the storage housing ( 11 ) to decrease progressively, and the volume of the reception housing ( 15 ) to increase progressively, said at least one movable wall including two pivot walls ( 600 , 601 ) one of which ( 600 ) is concave relative to the reception housing ( 15 ) and the other one of which ( 601 ) is concave relative to the storage housing ( 11 ); wherein the two pivot walls are displaced under the effect of a corresponding thrust exerted thereon by the elongate strip; and said two pivot walls slide one against the other while pivoting about a respective pivot, a free end of one of the two pivot walls extending generally toward the respective pivot of the other of the two pivot walls.
