Abstract: The present invention relates to a device for closing a dispenser of liquid products, comprising a push-button equipped with a lateral ejection aperture and characterized in that it comprises a bonnet enclosing said push-button and equipped with a vertical panel capable of closing the said aperture by rotating the said bonnet around a central pivot on the upper surface of the said push-button.

Abstract: The invention relates to a liquid or pasty product dispenser comprising a mounted working piston. According to the invention, the dispenser comprises a hollow body with a piston mounted therein and a toothed wheel is connected to the piston by means of threads, said piston being blocked in rotation in the body. In this way, when the toothed wheel is actuated, the piston moves axially and the product is dispensed in a controlled manner. Preferably, an outlet-sealing needle valve passes through the piston.

Abstract: The push-button is made up of two parts which fit into each other and define between them a whirl chamber, a part of which is formed by a cavity (38) defined inside the outer part on a face of the latter that is tilted in a direction and at a sufficient angle (?), suitable for making it possible to remove the outer part from the mould “along the axis” without damaging the cavity.

Abstract: A liquid cosmetic product dispenser includes mainly a reservoir, an internal piston and an applicator nozzle provided with an end valve. The reservoir consists of a base provided with an axial rod on which the piston can move longitudinally by rotating the base in relation to the nozzle.

Abstract: An atomizer provided with a manually activated pump forming a stopper, which is mounted by force in the opening of the bottle. The bottle is made entirely from a plastic material, moulded as a single piece, and the opening of this bottle comprises on the inside an annular hooking rib and the plastic material used to make the bottle is harder and more rigid than the material used to make the pump body so that the said rib can encrust in the pump body.

Abstract: The dispenser comprises a reservoir and a pump that is activated by a tappet, comprising a pump body that includes a tubular part with a smaller gauge than that of the reservoir, covering the piston, and an annular spacer by means of which it is tightly mounted against the inner wall of the reservoir such as to define an annular chamber for the product, which communicates with a dosage chamber located in the bottom of the reservoir.

Abstract: A pump intended to be assembled in the neck of a bottle containing a product to be sprayed. The pump includes a body made from flexible material containing the pumping mechanism, in which a rigid sleeve provided with a ring is embedded, the ring being able to form above it an annular space of sufficient dimensions to enable the body to work when assembled essentially under flexion.

Abstract: The invention concerns a nozzle for spraying a product, comprising a cylindro-conical body (10) having an axial channel (12) delimited at its upper end by a transverse wall (18) having a spraying orifice (20). An axial core (24) is arranged in the channel (12) and its upper end (24A) is located opposite the transverse wall (18) for delimiting therewith a spraying chamber (21). A communication between the lower end (12B) of the channel and the spraying chamber is provided between the core and the channel wall, whereof the lower end is capable of communication with a reservoir containing the product to be sprayed. The core (24) includes means forming a catching flange (26) having a catching edge (28) facing the lower end of the core and co-operating with the channel wall (13) to maintain the core in said channel.

Abstract: The invention relates to a valve nozzle for a dispenser for a liquid cosmetic product, the nozzle including a reservoir and an internal piston which is actuated by the displacement of a base. The inventive nozzle is characterised in that it comprises a cap which closes the reservoir and is provided with a dispensing opening that can be closed in a sealed manner by a pin fixed to a spacer which is arranged inside the cap in a sliding manner and is provided with at least one line which successively ensures the emptying of the reservoir and the discharge of the product. According to the invention, the cap and the spacer define a space with a wall that has at least one elastically deformable region, enabling the pin to retract from the dispensing opening, following the actuation of the piston, in order to ensure the discharge of the product.

The distributor includes a reservoir and a manual action pump, provided with a hollow push-button, arranged such as to slide in a sealed manner with relation to the exterior of a tubular neck of the pump body, defining a dosing chamber, extending at least partly into the interior of the push-button.

Abstract: A dispenser for a liquid cosmetic product, includes a reservoir, an internal piston, and an applicator end piece provided with and end valve. The dispenser is characterised in that the reservoir is defined inside the end piece, at a first end, by the valve, and, at the other end, by the piston, the piston forming a stopper screwed onto a threaded axial rod fixed to a base which is rotatably connected to the end piece.

Abstract: A sprayer push-button with a lateral spraying outlet. The push-button is made up of two parts which fit into each other and define between them a whirl chamber, a part of which is formed by a cavity (38) defined inside the outer part on a face of the latter that is tilted in a direction and at a sufficient angle (?), suitable for making it possible to remove the outer part from the mould “along the axis” without damaging the cavity.
