Abstract: A fluid dispenser assembly characterized in that it comprises: a fluid dispenser (1) defining a substantially flat body (10) provided with a dispensing orifice (17) and with a removable closure member (18) suitable for closing the dispensing orifice (17); and packaging (2) encasing the dispenser (1) and forming an opening portion (24, 28; 240, 280) in which the removable closure member (18) is received so that it is possible to take hold of it in order to remove it from the body, thereby unmasking the dispensing orifice.

Abstract: A fluid dispenser for dispensing a fluid in the form of a powder, said fluid dispenser comprising a fluid reservoir (23) provided with a movable actuating wall (22) and with a spraying orifice (53), the reservoir containing a piece of porous material (4) suitable for being impregnated with gas and with the fluid in powder form, said fluid dispenser being characterized in that the porous material occupies the major part of the volume of the reservoir.

Abstract: A fluid dispenser for dispensing fluid in liquid or powder form, the fluid dispenser comprising a fluid reservoir (30) of variable volume, said reservoir defining at least one movable wall (31, 32) that can be moved to vary the volume of the reservoir, the dispenser further comprising a dispensing orifice (311) in communication with the reservoir so that fluid from the reservoir can be delivered through the dispensing orifice when the volume of the reservoir is reduced;

Abstract: 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 of 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.

Abstract: A spring (4) comprising two branches (41, 42) is connected by a bend (40) such that the branches form, in the idle position, an acute angle. Said branches are elastically mobile in relation to each other by relative pivoting around the bend until they come into contact with each other so as to be extended relatively in parallel. The spring also comprises a spring stiffness variation systems (43, 44) which produce different stiffnesses depending on whether the spring is compressed or slackened. Said variation system producing a low stiffness when the branches are extended relatively in parallel and a greater stiffness when the branches are forced together from the idle position.

Abstract: A fluid dispenser assembly having, a fluid dispenser (1) defining a substantially flat body (10) provided with a dispensing orifice (12) and with a removable closure member (15) masking the dispensing orifice, packaging (2) encasing the body (10) of the dispenser while leaving the removable closure member (15) accessible so that it can be removed from the body. The dispenser assembly being characterized in that the packaging (2) comprises a casing portion (3) containing the body (10) of the dispenser; and a substantially plane portion (4) connected to the casing portion (3) by zones of least resistance (43), so that the casing portion (3) can be separated from the plane portion (4).

Abstract: A fluid dispenser assembly comprising: a fluid dispenser (1) defining a fluid reservoir (11), a deformable actuating wall (12), and an outlet orifice (13); and packaging (2) defining a casing (21, 22) surrounding the dispenser (1), the actuating wall being pushed in via the casing; said fluid dispenser assembly being characterized in that the packaging further comprises a hinged flap (23, 24) that can be folded over onto the casing (21, 22) so as to be superposed thereon, the flap being secured to or integral with the casing via a side edge (25), the flap comprising an outside face (23) and an inside face (24) serving to come into contact with the casing when the flap is folded over on the casing.

Abstract: Fluid product dispenser, including a fluid product pack (2) defining a fluid product container, a dispensing orifice, and a removable sealing part (25) sealing the dispensing orifice; and a case (1) wherein the fluid product pack (2) is inserted by sliding so as to take the pack out of its case to remove the removable sealing part. The fluid dispenser also includes a stopping feature (16, 26, 265) to limit the sliding of the pack in the case.
