A fluid dispenser (100; 200; 300; 400) for dispensing a fluid in liquid or in powder form, the dispenser including a reservoir (12) serving to contain fluid, and a dispensing orifice (114; 214; 314; 414) via which the fluid is dispensed. The reservoir (12) having an actuating wall (111; 211; 311; 411) and a backing wall (112; 212; 312; 412), the 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. The dispenser further having 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, wherein 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.
A fluid dispenser (100;
A fluid dispenser having a one-piece body comprising two blades respectively defining actuating and backing walls, said two blades being connected together at a coupling portion so that the blades pivot relative to each other by elastic deformation of the coupling portion, said two blades being connected together by a sealing film, the body and the film forming together a fluid reservoir.
A fluid dispenser comprising a body constituted by a slice of deformable loop cylinder having two opposite loop edges (4161, 4162) on which two sealing films (421, 422) are respectively secured to close the cylinder and form a fluid reservoir, the cylinder having a dispensing orifice between the two edges.
