Description

The invention relates to the field of the application of a product, in particular a cosmetic product, and more particularly, but not exclusively, to the application of a cosmetic product. hair coloring product in the hair.

For the purposes of the present invention, the term "cosmetic product" is understood to mean a product as defined in Regulation (EC) No. 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products. The cosmetic product is advantageously in fluid form.

Hair coloring products are conventionally stored in a storage tank, for example, with deformable walls comprising a body provided with a closed end and an open opposite end forming a neck. The neck is generally provided with a thread on which is screwed an applicator for the distribution and distribution of the hair coloring product in the hair.

Today, there are distributors and applicators of cosmetic product for dispensing the cosmetic product through an outlet orifice formed on a tip protruding from the tank containing the cosmetic product.

Reference can be made in particular to document WO-A1-2013 / 037925 (L'Oréal) which describes a dispenser comprising a connection member allowing a removable assembly on the product storage tank. The dispenser also comprises a product dispensing nozzle, a support member of the nozzle, a shutter protection of the nozzle and an actuator member of the shutter.

The dispenser described in this prior document further comprises a locking mechanism adapted to allow or prevent dispensing of the cosmetic product depending on the angle of inclination of said dispenser. The sealing of such a dispenser is however not satisfactory. In addition, when product remaining at the outlet orifice is allowed to dry and solidify, dispensing of the product can be hindered or even prevented in future use.

The present invention therefore aims to solve these disadvantages.

More particularly, the invention aims to provide an application device for limiting the risk of clogging the outlet of the product after a first use, while having an improved seal. The subject of the invention is an application device for a packaging and dispensing assembly of a product, in particular a cosmetic product, of the type comprising a product storage tank. The application device comprises a mounting base intended to be mounted on an open end of the reservoir, and a product applicator provided with a dispensing orifice of said product and movable relative to the mounting base between a position of product distribution and a closed position. The mounting base comprises a perforating member adapted to close the dispensing orifice in the closed position of the applicator. Said perforation member extends through said dispensing orifice in said closed position. Thus, the dispensing orifice is sealed by the perforating member. The perforating member makes it possible both to seal the mounting base and the applicator, and to perforate the film of product remaining in the dispensing orifice, for example after a first use of the device. application. The perforation member thus performs a dual function of sealing the dispensing orifice and drilling or perforation of product remaining adhered to the inner wall of said orifice after use. The perforating member is shaped so as to promote this drilling. The dispensing orifice is in shape with one end of the perforating member, in order to increase the sealing of the application device, in particular between the mounting base and the applicator.

Advantageously, the applicator comprises a product application nozzle for the application of the product and a connecting member adapted to connect the applicator tip and the mounting base. The dispensing orifice is, for example, made on the connecting member.

In one embodiment, the mounting base comprises a mounting skirt intended to be mounted on an open end of the reservoir and a hooking skirt cooperating with the connecting member, for fixing the applicator on said base.

Advantageously, the grooves and the guide tabs are three in number, arranged at 120 ° from each other.

The helical grooves may be made such that the connecting member is movable a quarter turn relative to the mounting base.

In one embodiment, the mounting base comprises a product dispensing portion having an inner skirt coaxial with the attachment skirt, and said perforating member projecting axially outwardly. The perforating member and the inner skirt define a receiving cavity of the connecting member.

A product flow orifice is advantageously arranged radially between the inner skirt and the perforation member. Said flow orifice has, for example, the shape of a semicircular oblong hole.

In one embodiment, the connecting member comprises an outer mounting skirt in the applicator tip and an inner product inlet duct disposed in the receiving cavity and coaxial with said outer skirt. Said dispensing orifice opens into said inner duct allows the flow of the product contained in the receiving cavity to the outside. The inner conduit has, for example, an outer diameter greater than the inner diameter of the inner skirt of the mounting base, and includes, for example, externally, an annular boss. Thus, it assures an assembly on the mounting base with a tight fit to further increase the sealing of the device in the closed position. When the application device is in the closed position, if product flows through the flow orifice of the base, this product can not flow out of the device.

Advantageously, the connecting member comprises reliefs, for example grooves, cooperating with reliefs, for example splines, provided on the applicator endpiece, for driving the connecting member when the endpiece application is requested in rotation.

In one embodiment, the applicator tip comprises, at one of its ends, at least one row of teeth forming a comb for the application of the product, and an outlet orifice of said product, adjacent to the teeth and coaxial with the dispensing orifice. The applicator tip may comprise two rows of teeth forming two combs parallel to each other and arranged on either side of the outlet orifice.

The inner conduit 42 has on its periphery, an annular boss 42b for assembly on the inner skirt 36a of the mounting base with a tight fit to ensure a first seal of the device in the closed position. Thus, when the applicator device 14 is in the closed position, visible in FIG. 3, the product flowing through the flow orifice 36d can not flow outwards.

In this closed position, the axial pin 38a of the perforating member 38 is inserted into the dispensing orifice 44a and extends through said orifice 44a. The upper end of the perforating member 38 is centered sealingly in the orifice 44a of patterned distribution. This ensures a second seal of the device in the closed position. The applicator tip 20, visible in detail in FIGS. 6A and 6B, is made in one piece, for example by molding a synthetic material. The applicator tip 20 comprises the assembly skirt 48 radially surrounding the reservoir 12, the mounting base 16 and the connection member 22.

The assembly skirt 48 comprises, on its bore, an annular rib 48b of inner diameter smaller than the outer diameter of the outer skirt 40 of the connecting member 22 to allow axial support of a lower end of the body connecting piece 22, on the side opposite the splines 40d, on said annular rib 48b. The assembly skirt 48 furthermore has an internal shoulder 48c against which the splines 40b of the connection member 22 are axially supported. The rib 48b and the shoulder 48c prevent the translation of the connection member 22 with respect to the application nozzle 20. With the annular rib 48b and the splines 48a, the application nozzle 20 and the connecting member 22 are fixedly assembled relative to each other. Thus, when the applicator tip is turned a quarter of a turn, the connecting member 22 is jointly driven in rotation and moves axially relative to the mounting base 16 between the dispensing position and the position. closure. A third sealing of the device is performed between the inner shoulder 48c of the applicator tip 20 and the splines 40b of the connecting member 22.

The applicator tip 20 comprises, at one of its ends, two rows of teeth 50 parallel to each other and forming a comb for the application of the product contained in the reservoir. The teeth have, in the illustrated example, a parallelepiped shape. An outlet orifice 52 allowing the exit of the product opens out between the two rows of teeth 50 in the intermediate duct 46 of the connecting member 22. The applicator member 24 is housed partly between the two rows of teeth 50, in said outlet port 52 and extends axially beyond said rows of teeth.

When a pressure is applied on the reservoir 12, the product contained in said reservoir flows through the flow orifice 36d inside the receiving cavity 36c of the mounting base 16, then towards the application member 24 through the dispensing orifice 44a made in the connecting member 22 and the outlet orifice 52 formed in the application nozzle 20. The mounting base 16, the nozzle of FIG. application 20 and the connecting member 22 are made of synthetic material, to ensure assembly of the parts relative to each other by deforming slightly. By way of non-limiting example, the mounting base and the application tip are made of polypropylene homopolymer (PPH) and the connecting member is made of high density polyethylene (HDPE).

In the exemplary embodiment illustrated, the mounting base 16, the application nozzle 20 and the connecting member 22 are separate parts from each other.

For reasons of molding of synthetic material, it is easier to design the applicator 18 formed by the applicator tip 20 and the connecting member 22 into two separate parts. But, alternatively, it could be provided that the applicator tip and the connecting member form a single piece, movable relative to the fixed mounting base relative to the reservoir.

Thanks to the application device according to the present invention, the seal is increased in the closed position.

In addition, thanks to the perforating member 38, after use of the application device, when the product remaining in the dispensing orifice 44a forms a dry film, this does not prevent a new use of the device. application.

Indeed, the perforating member 38 allows to perforate the film of product remaining in said orifice 44a, thus releasing any obstruction, simply by moving the applicator 18 between the dispensing position and the closed position. The expression "having one" shall be understood as being synonymous with the expression "having at least one" unless the contrary is specified.
