Claim:
A fluid dispenser ( 100 ; 200 ; 300 ; 400 ) for dispensing a fluid in liquid or in powder form, said dispenser including a reservoir ( 12 ) serving to contain fluid, and a dispensing orifice ( 114 ; 214 ; 314 ; 414 ) via which the fluid is dispensed, said reservoir ( 12 ) having an actuating wall ( 111 ; 211 ; 311 ; 411 ) and a backing wall ( 112 ; 212 ; 312 ; 412 ), said walls be adapted to be brought towards each other by elastic deformation to reduce the volume of the reservoir, and thus to deliver fluid through the dispensing orifice, said dispenser further comprising a one-piece body ( 110 ; 210 ; 310 ; 410 ) and at least one flexible sealing film ( 120 ; 220 ; 320 ; 421 ; 422 ), the actuating wall and the backing wall being formed by the one-piece body, characterized in that the actuating wall and the backing wall are angularly positioned relative to each by forming an angle that decreases when they are brought towards each other; and wherein the body and the at least one film together form the reservoir.
