Definitions
- the present invention relates to an applicator tip for liquid products.
- the invention applies to cosmetic or pharmaceutical liquid or semi-liquid products intended to be used in particular on any part of the human body and in particular of the face.
- Traditional tips include an elastically deformable external application element provided with a dispensing orifice capable of being closed in leaktight manner by an internal closure element forming a valve.
- the present invention aims to solve these technical problems satisfactorily.
- This object is achieved, in accordance with the invention, by means of an applicator tip comprising a rigid internal body, the upper part of which carries said projecting obturation element and is furnished around said obturation element, of said application element. external.
- the rigid body is provided with a discharge channel contiguous to said closure element and closed by a flexible lip secured to said external application element.
- said applicator element is in the form of a skin fixed by overmolding on said rigid body by marrying at least partially its profile.
- said end piece has a cylindrical-conical profile and said dispensing orifice is formed on a bevelled face of the application element.
- said body has at least one groove for anchoring said application element.
- said closure element is in the form of a needle carried by the top of said body and flush with the surface of the application element.
- This needle is a cylinder with a bevelled circular facet.
- the lower part of said body is provided with connecting elements with a dispenser.
- Another object of the invention is a method of manufacturing an applicator nozzle for a liquid product for lips, characterized in that a rigid internal body of cylindroconical profile is provided, provided with an evacuation channel adjacent to an element of projecting obturation, then an external application element is produced in the form of an elastically deformable skin which conforms at least partially to said body and carries a flexible lip which is flush without residual adhesion to said obturation element.
- said applicator element is produced by overmolding of said body and, when the end piece is removed from the mold, detachment of said lip from the closure element to guarantee the absence of mutual adhesion.
- said external application element is made hot so as to allow, by subsequent cooling, its tightening on said body.
- said body and said skin are produced with two different materials and without interpenetration.
- An advantageous step of the process consists in producing the body by means of a molding, either by injection or by compression.
- the tip of the invention can be mounted on different types of dispensers and ensures both a comfortable and precise application of the product to the face or any other part of the human body.
- the proximity of the channel and the needle allows the lip, when the valve is closed, to eject the residual product.
- the application element can take various shapes and dimensions depending on the type of use envisaged.
- the method of manufacturing the endpiece is, moreover, particularly simple and easy to implement and therefore offers a very economical cost price.
- Figures 1A and 1B show sectional views of an embodiment of the tip of the invention respectively in the closed and open position.
- FIG. 2 represents a front view of the rigid body of the nozzle of FIG. 1.
- Figure 3 shows a sectional view of another embodiment of the tip of the invention.
- the end-piece of the invention has a cylindrical-conical overall profile with, in the embodiments shown in FIGS. 1A, 1B and 3, a truncated or bevelled face arranged here on the left side and an ogival top.
- This nozzle comprises a hollow rigid internal body 1 shown in detail in FIG. 2 and the upper part of which is furnished with an external application element 2 provided with a dispensing orifice 20 capable of being closed in leaktight manner by a internal projecting closure element 11 forming a valve.
- the lower part of the body 1 is provided with connecting elements C with the reservoir of a distributor (not shown).
- the external application element 2 covers the wall of the body 1, with the exception of the end of the closure element 11 which it surrounds flush with the truncated face of the endpiece where the product.
- the shutter element is here produced in the form of a cylindrical needle 1 carried by the top of the body 1 with a bevelled circular facet 1 lb situated in the plane of the truncated face of the application element 2 in order to '' offer a smooth and ergonomic application surface.
- the external application element 2 is produced in the form of an elastically deformable skin fixed to the body 1, at least partially matching its profile.
- the body 1 is provided with a product discharge channel 10, contiguous with the closure element 11 and closed, in the closed position of the end piece, by a flexible lip 21 integral with the application element external 2, as shown in Figure 1 A.
- the channel 10 opens onto the truncated face of the end piece, in line with the needle 11a and has a bean-shaped section as shown in FIG. 2.
- the reservoir When the dispenser is used by a consumer, the reservoir is pressurized and the product then engages in the channel 10 of the nozzle, as shown in FIG. 1B then, by lifting the lip 21 from the skin, s escapes outside, along the side wall of the needle 11a, before flowing on the truncated face of the application element 2.
- the deflection of the lip 21 takes place around an axis passing through the lower edge of the channel 10.
- the body 1 has an upper groove 12a as well as a lateral groove 12b ensuring the anchoring of the application element 2 in the wall of the body 1 to reinforce the fixation of the skin on the nozzle.
- the tip of the invention is produced in two main stages.
- the first step consists in manufacturing the body 1, in a traditional way, for example, by means of a molding (compression or injection) of a rigid plastic material.
- the next step is to make the skin 2.
- This operation is carried out, preferably, by overmolding on said body and around the needle l ia, using an elastically deformable material (elastomer type), preferably chemically different from the material constituting the body l so as to avoid any interpenetration of material at less with the needle lia.
- an elastically deformable material elastomer type
- Overmolding is carried out either in the same mold as that used to manufacture the body, or with another mold in which the body previously produced is placed.
- the overmolding is carried out hot and the subsequent cooling of the material constituting the skin is accompanied by a phenomenon of necking or shrinking which results in a tightening of the skin 2 on the body 1.
- the skin 2 must at least partially conform to the external profile of the body 1 and is flush with the facet 11b of the link shutter needle thus delimiting a flat surface for applying the product.
- the thickness of the skin 2 is between 0.1 mm and a few millimeters and the flexible lip 21 may have a thinned profile to promote its movement and / or improve the tightness and the precision of the dosage.
