Abstract: The invention relates to a device for selectively dispensing liquids from a plurality of independent reservoirs (R), each of which is equipped with a drawing-off member (P) provided with a dispensing head (T) suitable for being actuated by being pressed axially, said device being characterized in that it comprises a single push-button (1) whose bottom face (1a) is provided with a series of axial bushes (10) suitable for engaging simultaneously and removably over one or more dispensing heads (T) by means of said push-button (1) being turned and angularly keyed on a central bearing (2) secured to the reservoirs (R).

Abstract: A handle device for manually grasping an airless dispenser of the type including a drawing-off member provided with a dispensing head and fitted to a flexible pouch by means of a cylindrical fitting, wherein, at the top of the fitting, under the head, the fitting is provided with a set of fins whose bottom faces serve to receive and to be pressed by the fingers of the user.

Abstract: The invention concerns a liquid or gel product dispenser, comprising a reservoir (R) supporting a pump body (1) including in its lower part an intake valve (2) and provided with a piston (3) mobile along an axis, defining with said body a metering chamber communicating with at least an ejection orifice defined in an axially mobile dispensing nozzle at the end of the reservoir; said piston is coupled by friction with said dispensing nozzle, which is axially mobile in both directions by manual actuation, relative to said reservoir; said metering chamber comprises a lower section (10a) and an upper section (10b), both sections communicating via a conduit (30) arranged across said piston and a closure valve (5) is arranged between said piston and said nozzle.

Abstract: The invention concerns a device for dispensing a dose of liquid or gel products comprising a dispensing head axially mobile mounted on a product reservoir and provided with an outlet conduit and a metering chamber delimited by an intake valve and by a piston whereof the rod is connected to said head and which is equipped with an exhaust valve. The invention is characterized in that the rod of the piston extends inside the chamber through a projecting lower end providing sealed locking of the intake valve when the head is in low position.

Abstract: The invention relates to a liquid dispenser of the type comprising a reservoir (R1, R2) provided at its top with an outflow orifice (V) which is closed off by an inlet valve (a) and which opens out into a metering chamber (10) of variable volume, which chamber communicates, via an outlet valve (e), with a discharge duct (c) provided in a dispensing head (T), the dispenser being characterized in that the metering chamber (10) is defined by a wall of a bellows (1) that is elastically deformable, at least in part.

Abstract: The invention relates to an air-intake device for drawing air into a liquid dispenser equipped with a rigid reservoir (R) and with an atmospheric pump (P) provided, in particular, with a cylindrical and conical body (C) underlying a support flange (S) fixed to the reservoir (R), said device being characterized in that it comprises a sleeve (1) designed to be fitted around said body (C) of the pump, under said flange (S), and having its bottom portion provided with a vent-forming collar (10) whose inside wall which serves to come into radial clamping engagement against said body has a surface state such that said collar (10) is both impermeable to the liquid and also permeable to air.

Abstract: The invention relates to a device for selectively dispensing different liquids (I, II) from a single item of packaging containing a plurality of independent reservoirs (R1, R2), each reservoir having a drawing-off member (P1, P2) equipped with a dispensing head (11, 12) and suitable for being actuated by relative movement of said head, said device being characterized in that it comprises a central housing (1) supporting the reservoirs (R1, R2) peripherally and movably relative to the associated dispensing heads (11, 12) secured to or integral with said housing (1), and including a selective locking key (2) for selectively locking said reservoirs in positions in which they are fixed relative to said heads (11, 12).

Abstract: The invention relates to an air-intake device for drawing air into a liquid dispenser equipped with a rigid reservoir (R) and with an atmospheric pump (P) provided, in particular, with a cylindrical and conical body (C) and with a support flange (S) fixed to the neck of the reservoir (R) while bearing against a sealing gasket surrounding the pump body, said device being characterized in that it comprises a flat annular gasket-forming washer (1) whose free edge (10) is in leaktight abutment towards the outside under a frustoconical shoulder (20) carried by a collar (2) engaged over said pump body, and is capable of being deformed elastically under the effect of internal suction to enable air to be drawn in.
