Description

Organ of application with teeth.

The present invention relates to sets for the distribution of a product, and particularly a product cosmetic. The invention is more particularly suitable for the application on hair of hair coloring products in Foam, gel, paste or cream form.

By "cosmetic product", a product as defined in Council Directive 93/35 / EEC of June 14, 1993.

Many sets are known that comprise a container and an application part provided with teeth, in whose holes open holes that allow the hair to distribute product contained in the container. Can be mentioned particularly the French patent application FR-A-2 782 614 describing a example of device comprising two rows of teeth ends, rectilinear, with, between them, an intermediate row of lower teeth

On the other hand, documents are known US-2005184091 and US-6688314 nozzles which will be mounted in jars, these nozzles comprising several distribution holes, each distribution hole being surrounded by a row of spikes planned to comb the strands of hair when the nozzle is coupled with a lock of hair to coat it with the product contained in the bottle.

There is a need to improve more sayings sets, to particularly allow a product application in tufts in a mane to be treated. In effect, when a user apply the product on strands herself, she wishes to apply selectively the product in the identified strands, without that the product overflows the rest of the mane. This result is difficult to obtain to the extent that a lock is constituted by a limited number of hair fibers, which do not allow retention by capillarity an important volume of product between them.

The known application devices in the prior art does not allow precise dosing of the amount of product released in the hair. It is frequent then that the product drips at the end of the tuft or is deposited in areas of hair adjacent to said strand. In effect, the product to be distributed is usually contained in a container of compressible walls on which the user exerts a pressure to push the product in the direction of its distribution hole and ensure its distribution. Now it is difficult for the user dose the force you apply on these walls on one side to Start the flow and then regulate it.

The invention responds to this need thanks to a new application body for the application of a product in a support, said application body comprising:

-

a base comprising a passage to communicate a container that contains said product with a base distribution hole, Y

-

a plurality of teeth, each of said teeth having a free end and one end attached to the base, protruding the teeth of the perimeter of the distribution hole, such that at less one of said teeth comprises an elbow between its end free and its end attached to the base to form a flow reducer of the product coming out of said hole, and such that this end attached to the base is located at a distance from an internal edge of said perimeter.

One of the advantages of an application body according to the invention is that it is inexpensive to manufacture in the extent to which it is easy to mold and unmold. In particular, the tooth or teeth comprising an elbow can be demoulded to the force, subjecting them to slight torsion during the removal of the mold.

Thanks to said application body, the user You can also see the product that begins to flow out of the distribution hole, but still retained between teeth protruding around this hole. In this way, the user can regulate the product flow by viewing this indicator of presence of product between protruding teeth.

In particular, some of the teeth are arranged according to a closed curve, such that the free end of one of these teeth extends into the curve. He term "curve" should be understood broadly and encompasses successions of teeth arranged following a path that it comprises one or more rectilinear segments, forming this trajectory for example a regular polygon or not, particularly a rectangle or rhombus In a particular embodiment, the curve mentioned above is circular.

In particular, those of the teeth that they have according to a closed curve each presents its end free converging towards an axis that passes through the center of gravity of the curve.

A tooth may have a structure that is not rectilinear between its basal portion attached to the base and its end free. In particular, a tooth comprises at least one point of inflection that forms said elbow.

A basal portion of a tooth comprising the end attached to the base can extend along a first axis perpendicular to the plane in which the orifice of exit, while a terminal portion of this tooth, which It comprises the free end of the tooth, it can extend along of a second secant axis with the first axis.

Particularly said basal portion may have a length along the first axis less than a third, and preferably of the order of 1/10 emo of a total length of this tooth Corresponding the total length of a tooth to the sum of the length of the basal portion and the length of the terminal portion, along their respective axes of extension. In particular, the length of this basal portion is less than 3 millimeters and preferably of the order of 0.5 millimeters In particular, this length represents between 2 and 20% and preferably between 5 and 10% of the total length of the tooth.

According to a particular embodiment, the Second axis forms an acute angle with the first axis. For example, this acute angle is of the order of 30º, and as a variant it is between 20º and 90º. In particular, the higher the acute angle, the greater the length of the basal portion with with respect to the total length of said tooth.

For example, a tooth can comprise a decreasing section from its end attached to the base until its free end Particularly, in the case where the tooth is conical trunk, its cross section is then practically circular and the diameter of this section then varies for example between 0.6 and 0.4 millimeters from the base to its free end.

In particular, the spaces between the teeth they can be such that they allow hair to pass between teeth, particularly allow a relative movement of translation between said organ and a lock of hair with which It is coupled.

According to a particular embodiment, the Application body comprises an axis of symmetry of revolution.

For example, the enforcement body may comprise a plurality of product distribution holes,  these holes being surrounded by said plurality of teeth.

The teeth can be made in a elastically deformable material. For example, they are made in natural or synthetic rubber or in a thermoplastic elastomer. They can Obtained by injection of a thermoplastic material.

Particularly, the teeth may be made in one piece with the base. The fact of being able to use  industrial molding techniques, allows the realization of a application body with a very low manufacturing cost.

The teeth may be arranged to define a conical portion such that the free ends of these teeth delimit the section of smaller diameter of this portion conical trunk

In particular, the application body may be provided with a removable cap suitable for sealing the distribution hole. This removable cap may be attached by anchoring in said application body.

The invention also relates to a set for the distribution of a product that includes

-

a container containing the product to be distributed, and

-

a application body according to the invention, the means of application means for mounting it in said container of so that an opening of the container is in fluid communication with the distribution hole of the application body.

In particular, the container of said set It can be shaped to act as a clamping body. It can also comprise a compressible wall to facilitate the product distribution. In particular, in said set, the application body can be removably mounted on the container. In this case, the container is first filled with product and then the application body is mounted on said container. Preferably, the application body is already provided with its cap when the application member is mounted on the container, the container is then sealed.

Figure 1 shows an application body 1 of according to the invention. This organ 1 comprises a base 2 provided with a distribution hole 3 and an arrangement of 4 protruding teeth on the outer perimeter of the base 2. In in particular, these teeth 4 each comprise an end 5 attached to the base and a free end 6.

The teeth 4 are preferably implanted at the perimeter 7 of the distribution hole 3. Preferably, teeth 4 are implanted according to a closed curve C, figure 2. According to the embodiment shown, the teeth 4 are distributed equidistant in this curve, and the closed curve C is circular. As a variant, the curve can comprise segments straight and be polygonal or even ovoid.

Preferably, the distribution hole 3 is defined in a plane P, figure 3, so that the curve C is defined in this plane so that it surrounds the distribution hole 3. In particular, the perimeter 7 defines an annular zone in said flat P.

The ends 5 of the implanted teeth 4 according to the closed curve C they are located at a distance from an inner edge 8 of the perimeter 7 delimiting said hole 3. These are also at a distance from an outer edge 9 of said perimeter 7. In the embodiment shown, edges 8 and 9 are concentric and respectively circular. In particular, the diameter of the edge 8 is between 3 and 8 mm and preferably between 4 and 5 mm

The teeth 4 are arranged so that at least one of these teeth 4 has its free end 6 towards the inside the closed curve C. In particular, all teeth 4 arranged according to the closed curve C have their free end 6 in the inside of curve C. Preferably, the free ends 6 of teeth 4 extend above the distribution hole 3, so that the projections along the Z axis of the different free ends 6 in the plane P define points located in the inside hole 3. These points are preferably distributed equally in the perimeter of a circle C ', inscribed inside of the inner edge 8, having the circle inscribed C 'a diameter between 1.5 and 7 mm.

According to the embodiment represented, the free ends 6 of these teeth 4 converge all towards a Z axis perpendicular to the plane P and passing through a center of gravity of the surface bounded by the inner edge 8.

In particular, as shown in Figure 3, a tooth 4 comprises a basal portion 10 which extends along an X axis perpendicular to the plane P, the portion 10 being delimited on one side by the end 5 attached to the base 2. The tooth 4 comprises on the other side a terminal portion 11 which extends along a second Y axis, and which forms an elbow 12 with the basal portion 10. The terminal portion 11 has the free end 6 opposite the elbow 12. The second axis Y is secant with the X axis. This forms, in the example shown, an acute angle of the order of 30º with the
X axis.

The tooth 4 has a represented length essentially by the length between elbow 12 and the free end 6. In this case, the length of the basal portion 10 with respect to the X axis is of the order of 0.5 to 1 mm, while the length between the elbow 12 and the free end 6 along the Y axis is of the order of 4 to 9.5 mm. In the opposite direction, tooth 4 could also have a length essentially represented by the basal portion 10, and in this case, the length of the basal portion 10 could then represent up to 95% of the accumulated length of tooth 4.

For example, tooth 4 has a section circular transverse, such that the external diameter of the section transverse of tooth 4 decreases as it moves away from the base 2. For example, it is of the order of 0.6 mm at the level of the joined end 5 to base 2 to reach a diameter of 0.4 mm at the level of its free end 6. The free end of the tooth is preferably rounded so that it does not produce wounds on the scalp. How variant, the teeth 4 can be of polygonal cross section or ovoid.

In particular, teeth 4 arranged according to the closed curve C are identical to each other and are arranged so that their respective end portions 11 define the surface of the envelope of a truncated cone.

To allow product distribution, the base 2 comprises a passage 13 leading to a first end through the distribution hole 3 and suitable to be in communication, at a second end 14, figure 4, with said product. In particular, this passage 13 is of variable section between the hole 3 and the second end 14, particularly comprises a bevel 15 that opens at the level of hole 3 to reduce progressively the cross section of said passage 13. The product flow that can flow through said organ of application 1 is, among others, depending on the smaller section cross section defined by this passage 13. In particular, the smallest cross section of this passage 13 is defined at the level of second end 14, and in the case where it is circular, this The latter has a diameter between 0.5 and 5 mm.

The base 2 is intended to be mounted on a container 16, figure 5. In particular, it comprises a skirt 17 which comprises fastening means 18 suitable for cooperating with the container 16. The skirt 17 is preferably provided for engage with the outer perimeter of a neck 19 that delimits a opening 20 of container 16. Preferably, base 2 is removably mounted in container 16. For example, the fastening means 18 correspond to a thread suitable for engage with a complementary thread 21 present in the external perimeter of the neck 19.

On the other hand, to ensure the tightness of the assembly of this base in the container 16, the base 2 comprises a sealing skirt 22 suitable for engaging in a sealed manner, in particular by friction, with the outer perimeter of the neck 19.

To limit the flow of product that can flowing from the opening 20, the base 2 comprises a portion conical trunk 23 that joins the sealing skirt 22 to one side bottom 24 of the perimeter 7 of the hole 3, this face being lower 24 opposite the face of the perimeter 7 from which they protrude the teeth 4. In particular, this conical portion 23 is extends to the outer edge 9 of the perimeter 7, so that the passage 13 extends partly inside the volume delimited by this truncated conical portion 23. Thus, the Product flow rate is progressively reduced before entering the passage 13.

In the case where the product is packaged in the container 16 for storage before use, preferably the container is equipped with a means of plugging 25. In particular, this plugging means is in the form of a plug 25 mounted on the application member 1 to seal the distribution hole 3. In particular, this cap 25 comprises a pin 26 suitable for insertion into the passage 13 to ensure a tightness. The bezel 15 then serves as barbed guide means 26 in passage 13. On the other hand, the passage comprises locally an annular groove 27 in which will engage an annular weatherstrip 28 of the spike 26.

The teeth 4 are arranged around the hole 3 and arranged so that they can deform so reversible when subjected to stress, particularly during the insertion of the spike 26 in the hole 3.

The plug 25 is removably mounted on the application body 1. In particular, it can be held by anchorage. In this case, it comprises a mounting skirt 29 from a bottom 30 of which it exceeds pin 26, this mounting skirt being 29 equipped with reliefs 31, particularly in the form of grain of rice, suitable for cooperating with a ring seal 32 outer perimeter of the truncated cone portion 24 of the base 2.

For the realization of an agreement set with the invention, for the application of a coloring product capillary in tufts of a mane, the organ of application of the container 16, to insert into said container 16 the different constituents that will form the product to apply. To do this, to facilitate the handling of the application body 1, the latter comprises a zone 33 of its outer toothed perimeter  to improve grip and finger grip around the base 2.

Then the user closes the container 16 by means of the unit formed by the application body 1 and its cap 25 to shake the assembly so that the product. As a variant, this stage can be omitted, if the product to be applied is ready for use and already packaged in the container 16.

To perform the application, the user detach the cap 25 and grab the container 16 to present the set "upside down", ie the distribution hole 3 located under the mass of flowing product, partly by gravity and optionally under the effect of stresses exerted on the outer perimeter of container 16, when the latter comprises deformable walls The product then flows beyond the distribution hole 3 and arrives in the form of a drop, due to the widening of passage 13 between its end 14, in communication direct fluid with the contents of the container 16, and the orifice of distribution 3.

This drop of product does not escape the set and is then retained by surface tension in contact with the teeth 4, in the space delimited by the arrangement of these teeth 4. The user then sees the product in the gaps between 4 teeth and knows that the application can start then, just you have to adjust the flow rate based on the inclination given to the container 16 with respect to the vertical and optionally regulating the pressure exerted on the walls of the container 16 when The latter are flexible.

To distribute the product in a lock of hair, the user couples one end of the strand between the 4 teeth to load it from the amount of product retained by these teeth 4. The teeth 4 are deformable to ensure a smoothing of the distributed product when the assembly moves to length of the lock in the direction of its opposite end. During said relative displacement between the distribution hole 3 and the tuft, the latter is preferably covered over its entire length, in effect the user ensures through said set a flow product continuum, selecting the appropriate inclination of the set and / or selected the pressure exerted on the walls of the container 16.

Said set allows a user to draw High precision and fine wicks directly on your mane.

As a variant not represented, the organ of application 1 can comprise several holes inside the closed curve C, which is particularly useful for limiting the product flow at the level of distribution hole 3, particularly when the product is very liquid.
