Definitions

• Valve cap for dispenser of liquid cosmetic products
• the present invention relates to a valve tip for a liquid cosmetic product dispenser.
• dispensers comprising in particular, a reservoir and an internal piston actuated by displacement of a base.
• dispensers are generally equipped with an end valve or valve ensuring jointly the sealing of the reservoir and the delivery of the product.
• the valve is often integrated into an applicator tip which is produced either in one piece with the reservoir, or in attached form.
• This operation which is carried out at the manufacturer of the product, must be simple and easy to implement so as not to entail additional production costs and / or quality defects.
• the precision of the dosage depends closely on the sensitivity of the valve and its ability to react in response to the overpressures generated by the movements of the piston, even for small amplitudes corresponding to small doses.
• Sealing for its part, is based on the speed and reliability of the return of the movable elements of the valve to their rest position. All these constraints are as many technical problems as the tip of the invention proposes to solve.
• a nozzle characterized in that it comprises a cap closing the reservoir and having a dispensing orifice which is capable of being sealed in a sealed manner by a lug secured to a spacer housed in a sliding manner inside the cap and provided with at least one conduit successively ensuring the venting of the reservoir and the evacuation of the product, said cap and said spacer delimiting between them, an enclosure whose wall has at least one elastically deformable zone allowing to release the lug from the dispensing orifice, following the actuation of the piston, to ensure the delivery of the product.
• said deformable zone is carried by the upper part of the cap, around the dispensing orifice.
• said conduit is then produced through the spacer.
• said deformable zone consists of the upper wall of a gas cell, supporting said lug.
• said cell is then secured to said spacer.
• said conduit is here produced around the periphery of said cell.
• the lower periphery of said spacer is provided with a connecting member with the upper edge of the tank.
• said cap comprises a skirt coming in radial tightening with the external lateral wall of the reservoir.
• said cap has an internal stop limiting the upward sliding of the spacer during assembly on the tank.
• Another object of the invention is a method for packaging a liquid cosmetic product in a dispenser comprising a nozzle according to the invention, characterized in that, after filling, said cap is fitted onto the reservoir with the internal spacer in low position to clear the dispensing orifice, then press on said nozzle while escaping the included air to the outside, via the duct, the enclosure and the orifice until the spacer comes first in abutment, down against the upper edge of the tank and then, the cap abutting against the spacer, while the lug engages in a sealed manner in the dispensing orifice.
• the end piece is guided on the dispenser by sliding the cap on the side wall of the reservoir, thus offering a radial reach.
• the tip of the invention is particularly simple since it comprises only two parts (cap and spacer) which are capable of remaining attached to each other, forming a pre-assembled assembly, delivered to the customer with the other part of the distributor (tank, piston and base).
• the packaging method of the invention is, moreover, easy to industrialize since the final closing step consists of a simple fitting of the pre-assembled assembly onto the tank with automatic exhaust of the air included.
• this fitting is guided by the cooperation between the skirt of the cap and the wall of the tank providing a radial reach.
• Figures 1A and IB show sectional views of a first embodiment of the nozzle of the invention mounted on a distributor, respectively in the rest phase and in the distribution phase.
• Figures 2A and 2B show sectional views of a second embodiment of the nozzle of the invention mounted on the same distributor, respectively in the rest phase and in the distribution phase.
• FIGS. 3A to 3D represent schematic views of the different stages of the packaging method of the invention.
• These distributors D include in particular and primarily, a reservoir R and an internal piston P moved by manual actuation of a base E, and here, in particular, by rotation of said base about a vertical axis, relative to the tank R and the tip.
• the tip of the invention is capable of being mounted on distributors different from those which are represented here, and in particular on distributors whose piston is moved by axial displacement of the actuator.
