Description

Device for applying highlights of hair products {DEVICE FOR HIGHLIGHT APPLICATION OF A HAIR PRODUCT}

The present invention relates to an apparatus for highlight application of hair products. The device according to the invention is particularly suitable for self-applying a dyed product onto several strands of hair.

A "highlight" dye is a dye product that is only immersed in any part of the hair head to achieve an uneven color effect after treatment, resulting in a lighter or darker color tone than the original or full color tone of the hair head. Refers to a process that highlights any particular change in the hair head.

Hair dye products come in several varieties such as temporary dyes, semi-permanent dyes, and permanent dyes such as oxidation.

All such dyed products may be in the form of creams, foams, or rather dense liquids. Dyeing products in liquid or gel form can be used after selective mixing using porous means such as foams. However, most viscous products and products such as dough are present in the bowl after mixing the oxidizing agent and the bleaching powder in the bowls.

In order to apply the product present in the bowl, a device is known, such as a comb, a thin brush, or a combination of the two. Such a device is disclosed, for example, in FR-A-2 764 488 and US-A-4 691 720.

Such devices are, as mentioned above, generally impaired due to the same disadvantages, in particular due to the disadvantages that such devices are used by approaching the hair head from the outside. The product is deposited very little inside the hair and is substantially deposited on the surface of the hair strands so that the applicator is continuously moved from the root to the hair ends relative to the hair strands. However, experience has shown that during this movement, the user raises the applicator and is off the path along the curvature of the skull. For this reason, a large number of hairs are separated from the applicator and returned to the hair head. Thus, in the case of dyed products, the hair thus obtained is not dyed and the result obtained will be unsatisfactory.

In the case where a user self-applies a product, it has been found that in the above-described apparatus of the prior art, handling for forming a highlight on the rear of the head is difficult. This is because it is difficult to precisely position such devices when used in hair heads that are out of view.

In addition, when a very doughy product is deposited, it is difficult to use a thin brush to spread the product over the entire length of the hair strand.

Document US-2,705,499 discloses a scissors-type applicator with two branches hinged about a rotation axis. The first branch consists of two rows of combs, between which the pads are immersed in the product, and the second branch is formed of a brush capable of supporting the immersed pads.

Such applicators are expensive and complex to produce because they are obtained by assembling a number of mechanical parts. In addition, the hinge of a branch of such an applicator often encounters a problem where the hair or part of the product interferes with the two branch hinges.

In documents US-2,722, 706 and DE-28,34,801, an applicator formed of a glove or fingerstall having an injector immersed in the product at the same height as the inner surface of the hand or finger bone, It was disclosed.

The problem is that such applicators are formed of a material that is necessarily different from the sprayable coatable product, i.e. the glove or finger wrap is in fact made of an impervious material for the product while the sprayer is formed of a permeable material for the product. Will occur. Moreover, the glove is not easy to handle for self-use of the product on the head, since the liquid in which the injector is immersed flows easily along the wall of the glove without covering the hair head at all. In addition, the finger wrapper has the additional problem of being able to rotate around the finger, especially when moving longitudinally along the hair strand.

It is an object of the present invention to overcome the above-mentioned problems by providing an apparatus for improving "highlight" self-application of hair products. The device according to the invention has a means for applying the hair treatment product to which the fixing means is mounted so as to be at the same height as the finger end.

For example, in order to improve the fixation around the finger, the finger is pressed against the outer surface of the flat base of the application means by the securing means.

One of the advantages of the device according to the invention is that it has the ergonomic properties of the application means, and the application means have a hand compressible container. The container of the application means can release the product when one of the walls of the container is compressed, including the batch of product. This may be at least partially compressed so that the wall of the container reduces its height with respect to the fixing means.

In order to cover the hair strands, the container can slide gradually from the hair root to the tip of the hair, in particular when it is moved longitudinally along the hair strands. The hair strands are advantageously immersed uniformly without depositing agglomerates, even if the product is in the form of dough, and the width of the highlights formed in this way is easily reshaped, resulting in uniform results over the entire hair head.

In the case where the application means have a tooth, the tooth preferably stands perpendicular to the application base to provide a central depression formed against the surface defined by the ends of the teeth formed together, the central depression forming a container. do. The teeth are also compressible.

In order to compress the container and release the product to the hair strand, the hair strand is physically gripped, for example, between the container opening of the application means and one or more other fingers of the hand. In this case, a compressive force is applied on the base of the container by at least one finger disposed in the fixing means on the outer surface of the base, and the container is compressed between the at least one finger and the other finger of the hand. Due to the advantages of the device according to the invention, there is no need to be very good at obtaining proper results. In one variant, the container may be compressed to grip laterally on a wall that defines an opening in which the hair strand is disposed.

In a preferred embodiment, the securing means can be adjusted to the diameter of the finger that is fitted around the securing means. In this connection, the fastening means have two tabs, which can be connected to one another, for example. In this case, the first tab can be inserted into the hole of the second tab, one of the tabs having various heights for fixing the second tab and the first tab. The two tabs preferably secure the fastening means around the front of the finger.

In order to prevent the pinching of the fingers around the pinch, at least one tab preferably has two arcs. The two arcs are attached at the same height as the application means and are connected to each other so that they can be jointly connected to the second tab. In addition, the position of the arc provides a very stable application means on the lower surface of the finger to which it is fitted.

In order to precisely position the application means at the last bone of the finger to be fitted around it, the application means further has a stop on the outer circumference to limit the insertion of the finger into the securing means.

In order to reduce manufacturing costs and improve the production and packaging of the device according to the invention, the device is integrally formed by casting or the like.

In order to promote the compression of the container, it is preferred to use a retaining member which acts as a support to position the hair strands in front of the container and against the opening of the container. This holding member can be fitted on the other finger by fixing means similar to the fixing means of the application means. In order to function to guide the finger fitted around the application means and the retention member, the application means is further connected to the retention member by means of a connecting element, preferably a flexible strip.

In order to cover the hair strand disposed between the application means and the retaining member, the application means and the retaining member move simultaneously by sliding along the hair strand from the hair root to the tip of the hair, and the connecting means for simultaneous movement of these two components. Guides are formed. Thus, the hair strands are physically gripped between two fingers of the hand, thereby moving the device along the hair strands more reliably and more straightly. Due to the advantages of the device according to the invention, there is no need to be very good at obtaining proper results.

In order to gradually eject the product contained in the container, the retaining member interacts with the opening of the container. In particular, the hair strand is gripped between the opening of the container and the retaining member because the retaining component can be folded into the opening. Thereafter, pressure is applied to each of the outer peripheral part of the container base and the outer peripheral part of the holding member. The pressure is obtained by holding between two or more fingers, for example between the thumb and index finger of the same hand.

When the hair strand is gripped between the application means and the retaining component, the application means and / or the retaining member to ensure that the hair strand is actually held between the two elements and covered with the hair product over the entire length of the hair strand. Has teeth that interact with the hair strands.

In order to improve the application of the hair product onto the hair strands, the retaining member can be produced to form the second application means. In this case, the second application means can also hold part of the product. Thereafter, the two application means are pressed against each other on one side of the hair strand. Thus, the hair strands are more advantageously immersed into the product. For example, the retaining member is a mirror image of the application means about an axis perpendicularly intersecting the connecting element.

The present invention relates to a device for the application of highlights of hair products,

i) application means capable of holding a large amount of said hair product,

ii) at least one fixing means disposed on said applying means, said fixing means fixing said applying means to at least one finger of a hand,

The securing means comprises at least one elastically deformable tab which can be held at least partially around the at least one finger, the applying means comprising a compressible container, in particular the device being moved longitudinally with respect to the hair strands. When applied, the application means is capable of releasing the product on the hair strands in accordance with the pressure of the hand applied to the container.

One wall of the container is advantageously compressible when subjected to a force applied perpendicularly to the base on which the fixing means are arranged.

In addition, one wall of the container is formed by teeth standing perpendicular to the base, which teeth define a central depression formed by a surface formed by the ends of the teeth formed with each other. As a variant, one wall of the container forms bellows, for example with a shape memory coil spring.

For example, the securing means may be adjustable according to the size of one or more fingers that are fitted around the securing means.

The fastening means preferably have two tabs which can be connected to each other. In this case, the tab can extend along both opposite directions of the coaxial. The tab (s) advantageously extend in the plane formed by the base of the container.

According to a particular embodiment of the invention, one tab is attached to the base of the container by two or more arcs. In this case, the two arcs may be elastically deformable.

The securing means advantageously comprises a stop on the outer periphery of the container in order to limit the insertion of the finger into the securing means.

It is also advantageous for the device to have a retaining member that can interact with the container to hold the hair strand fitted to the container so that the hair strand is covered with the product. In this case, the retaining member can be folded into the opening of the container and the hair strand is gripped between the opening and the retaining member and the pressure on the container is pinched between the base and the retaining member of the container on one side of the hair strand. Is applied. Optionally, the retaining member has a plate of a larger size than the opening of the container. As one variant, the retaining member may have a tooth. Alternatively, the retaining member may be the same as the application means.

It is also advantageous that the retaining member has a second fastening means which is fastened to at least one second finger. In this case, the second fastening means may have one or more elastically deformable tabs that can be held at least partially around the second finger. The fastening means preferably have two elastically deformable tabs which can be connected to one another.

The retaining member is preferably connected to the container by a flexible connecting strip.

In the case where the device is equipped with a flexible strip, the tab (s) may extend perpendicular to the flexible strip.

The apparatus is preferably formed integrally by casting, for example.

The invention will be more clearly understood from the accompanying drawings and the following description. The following description and drawings are illustrated by way of example and not by way of limitation.

1 shows an apparatus 1 according to the invention. This apparatus 1 is equipped with the application means 2. This application means 2 is provided with the base 12 and the container 27 arrange | positioned on the inner side surface 26 of this base 12. As shown in FIG. A batch of product may be stored in the container 27. This container 27 is preferably a hand compressible container, that is, the product stored in the container can be released by compressing one or more walls of the chamber. The wall 28 standing vertically on the base 12 of the application means 2 is compressed to reduce the volume defined by the container 27.

If the hair strand is placed against the opening of the container, it is preferable to gradually compress the wall 28 to deposit part of the product along the hair strand when the application means 2 is moved longitudinally relative to the hair strand.

The device 1 has one or more fastening means 5 which are fitted to one or more fingers 9 of the hand 7. The inner side 26 is on the opposite side of the outer side 13. The inner side 26 and the outer side 13 are concepts defined with respect to the position of the finger 9 fitted in the fastening means 5 on the application means 2, the outer side 13 being the same as the finger 9. While the inner side 26 corresponds to the side on the side, the inner side 26 corresponds to the side on the same side as the container 27 in contact with the hair strand.

In order to improve the application of the product on the hair strands, the application means 2 have teeth 25 which interact with the hair strands to be coated. The teeth 25 stand vertically on some or all of the surface formed by the inner side 26. The teeth 25 are arranged in rows, for example in particular close to the edge of the inner side 26. In FIG. 1, the heated tooth 25 forms a wall 28 and is compressible.

The teeth 25 preferably stand perpendicular to the lower face 26. This tooth has a height varying therebetween with respect to the plane formed by the lower surface 26. In particular, when teeth 25 are arranged on some or all of the outer periphery of the lower face, a central depression is formed between these teeth. In addition, the central depression can be formed by a surface defined by the ends of the teeth formed together. In this case, the depressions correspond to the area of the inner side 26 with the shortest teeth and form the container 27. Due to the tooth 25 it is possible to store a batch of product, especially when this batch of product is doughy.

In one variant shown in FIG. 2, the container 27 is formed by a continuous wall 28 extending beyond the edge of the base 12. Thus, in this case, the teeth are mutually continuous at their base. The tooth then forms a crenellation of the same height as the edge defining the opening of the container 27. This serrated form, for example, on the edge of the wall lying substantially on the axis on which the hair strands are arranged with respect to the application means 2. In this case, the tooth 25 functions as a comb.

For example, the container 27 has an open cylindrical shape or an open parallelepiped shape. In all cases, the hair strands are arranged to lie against the opening of the container 27 as shown in FIG. 3.

Hand pressure is preferably applied vertically on the outer surface 13 of the base 12. For example, pressure is applied by compression. In FIG. 3, in order to pressurize the container 27 to release the hair product into the hair strands, the fingers 9 fitted in the fastening means 5 exert pressure from the outer surface 13 and at least one second finger ( 8 works together with the finger 9 fitted in the fastening means 5.

The second finger 8 is arranged opposite the opening of the container, and the hair strand to be covered is arranged between the second finger 8 and the opening of the container 27. The second finger 8 is preferably the same as the hand corresponding to the finger fitted in the fastening means 5. The fingers selected to form the highlight are for example the index finger and the thumb.

The wall 28 of the container 27 can be compressed by the pressure action of the hand. Moreover, the wall has shape memory characteristics. In other words, after the initial compression, if the pressure is released, the wall will stand vertically, again forming the container 27 with the maximum internal volume. It can then be refilled with a large amount of product to be applied to other hair strands.

The container 27 is made of a flexible material, for example. It is preferable to use a flexible material having a hardness of 30 to 150 Shore A, and more preferably to have a hardness of 60 Shore A. Materials used are, for example, SEBS (chain styrene-ethylene-butadiene) polymers or injection moldable thermoplastic rubbers such as Santoprene (Available from Monsanto), or more generally from thermo-elastic materials.

The wall of the container 27 can have a bellows element that can be compressed to another wall by the action of pressure, as shown in FIG. 3A. For restoration to the initial shape, the wall may be provided with a coil spring as shown in FIG. 3B, for example one of these coil springs may be formed as a rib of the wall. The coil spring also defines an optional fold line of the wall 28.

According to the preferred embodiment shown in FIG. 4, the retaining member directly interacts with the opening of the container 27, and the hair strand to be covered is arranged between the retaining member 4 and the opening. Then, in the said embodiment, it is preferable that fixing means 5, 6 are respectively attached to the application | coating means 2 and the holding member 4, respectively. The fixing means is adapted to fit at least two of the user's fingers.

In the preferred embodiment shown in FIG. 4, the device 1 is then fitted to the finger of the same hand 7 of the user. The application means 2 is arranged on the thumb 9 of the hand 7 by the fixing means 5. Therefore, the holding member 4 is disposed on the index finger 8 of the same hand 7 by the second fixing means 6.

The retaining member 4 improves the compression of the wall 28. This provides a firm interface so that the walls 28 between these interfaces can be pressed more tightly than are used directly on the inner side of the second finger 8. Thus, the opening of the container 27 can have a dimension larger than the surface area of the inner side of the second finger 8. Thus, it provides an easy highlight with a width greater than the width of the finger bone.

The fastening means 5 and 6 can use different fastening mechanisms, respectively. This fastening mechanism is preferably formed in the same manner. Another variant of the fastening device according to the invention will be explained only in terms of the fastening means 5. Another embodiment of the fixing means 6 can be formed similarly to the embodiment of the fixing means 5, and the holding member 4 needs to be substituted for the application means 2, if appropriate.

In a first variant, the fastening means 5 has a first tab 10 adapted to interact with the second tab 11. The tabs 10, 11 form a strap that can be connected to each other. For example, the tabs 10, 11 are formed of a continuous base 12 formed by the application means 2. In this case, the tabs extend in opposite directions. The tabs are somewhat flexible and can be bent in the direction of each other on the outer surface 13 of the base 12. The tabs each have connecting means so as to be connected to each other, the connecting means being complementary to each other.

It is preferred that the fixing means 5 is adjustable in particular in the dimensions of the fingers to be fitted, for example the diameter of the fingers. For example, the first tab 10 has a plurality of holes 14, into which the protrusions 15 of the second tab can be inserted. It is preferred that the second tab 11 also has a plurality of protrusions 15 in turn. The two tabs 10, 11 are thus provided with adjusting means.

The protrusion 15 shown in FIG. 1 is forcibly inserted into the hole 14.

In one variant, the protrusions 15 are inserted without using force, and then the holes 14 have a shape similar to that shown in FIG. In this case, the hole 14 has a shape corresponding to two circular openings 14 ', 14 "connected to each other by the neck 16. The diameters of the circular openings 14', 14" are not the same. not. Thus, the protrusion 15 can be inserted into a larger diameter opening 14 'and as soon as it is inserted, the neck 16 enters into a smaller diameter opening 14 "that can prevent it from falling out. ), Considering the hole 14 of the first tab 10, it is preferred that the smaller diameter orifice 14 "is farther from the application means 2. This is because, due to the shape, as long as the tabs are constrained to connect, they tend to move away from each other and the protrusions 15 are retained within the smaller diameter openings 14 ".

In the variant shown in FIG. 2, the second tab 11 has an elongated tubular shape. The protrusion 15 corresponds to a chambered collar, the diameter of the foot 17 of this collar being greater than the diameter of the tube 11, so that the collar extends beyond this tube. The chamber is oriented so that the foot 17 is relatively closer to the application means 2. In this case, the larger diameter opening 14 'is larger than the diameter of the foot 17, and the smaller diameter opening 14 "is larger than the diameter of the tube 11 but the diameter of the foot 17 is larger. Is less than

In another variant, the securing means 5 is in the form of a finger wrap (not shown), in which one or more fingers can be inserted. In this case, the finger wrapper extends beyond the outer side surface 13 of the application means 2.

In another variant (not shown), the securing means has a single tab which interacts with the complementary means arranged on the outer surface of the application means 2.

The tabs 10, 11 preferably extend along opposite directions of the coaxial 18.

According to the first embodiment shown in FIG. 1, the tab extends along an axis 18 that divides the application means 2. Preferably, the last bone of the finger is placed at the same level as the outer side 13 of the base 12. In this position, hair products are applied more precisely.

In order to avoid pinching which may be caused by the fastening means 5, the tab is divided into two arcs. For example, as shown in FIG. 5, tab 10 has a first arc 20 and a second arc 21. The two arcs 20, 21 branch from the tab portion where the connecting means are located, and in this case branch from the hole 14 before being attached to the application means 2 at two separation points. For example, the space defined between the arcs 20, 21 may be a solid providing a tab 10, which tab 10 is larger near the application means 2 and thinner at the same height as the connection means. .

In the case where the application means is connected to the holding member by the connecting element 3, as shown in FIG. 5, the first arc 20 is connected to the outer circumference of the base 12 of the application means 2, and the second The arc 21 is directly connected to the connecting element 3.

In the shape where the second tab 11 also has two arcs 22, 23, respectively, these arcs are connected in the same manner as above and define the contour of the circle of arcs 20, 21. Thereafter, the segment 29 extends along the diameter of the circle, and the tabs 10, 11 extend perpendicularly and radially to the segment 20 toward the outside of the circle. The segment 29 is arranged on the axis of the finger fitted to the application means 2, and the tab surrounds the finger to be connected on the back side of the hand. Application means 2 is arranged on the segment 29. For example, in FIG. 5, the application means 2 is arranged at one end of the segment 29.

In one variant, the segment 29 corresponds to a part of the connecting element 3 and all arcs can be connected to the connecting element 3 or to the application means 2.

In order to improve the positional adjustment of the finger fitted at the same height relative to the application means 2, the fixing means 5 is provided with a stop portion 24 as shown in FIG. 3. In particular, the stop portion 24 preferably stands perpendicular to the outer side surface 13 of the base 12, and the stop portion 24 is arranged at the same height as, for example, the edge of the outer side surface 13. .

Base 12 may be rectangular or elliptical, for example. In this case, the stop portion 24 may be of straight or curved shape, which stop portion may be substantially U-shaped as described above, and the finger is in contact with the cavity of the U.

The connecting element 3 is for example a connecting strip extending along the axis 19 between the application means 2 and the retaining member 4. The axis 18 of the tab is then perpendicular to the axis 19. According to the second embodiment shown in FIG. 5, the axis 18 of the tab divides the connecting element 3. In the second embodiment, it is fixed around the front of the finger end.

In the first embodiment, the holding member 4 has a flat blade having a shape substantially the same as the opening shape of the container 27. In the embodiment of FIG. 3, the blades are round and have a diameter slightly larger than the opening diameter of the container 27. When the hair strand is supported by the retaining member 4, the outer circumference of the opening of the container 27 can be pressed against the blade. Compression, ie by bringing two fingers close together, can compress the vessel wall between the base 12 and the blade. The outer circumference of the opening is flawed so that the product is released when the container wall is gradually compressed.

In one variant, the retaining member 4 has an involute surface that more closely covers the fingers fitted to the retaining member. Since the index finger does not overlap in parallel with the original thumb, the involute surface can improve the parallel positioning of the retaining member 4 with respect to the application means 2.

In addition, the retaining member 4 can also have a tooth 25. In this case, the teeth can be oriented somewhat perpendicular to the blade, with the teeth extending from this blade. The hair strand is guided, for example, between the teeth of the retaining member 4 and the teeth of the application means 2.

In one variant, the retaining member 4 may also be similar in shape to the shape of the container 27. In this case, the retaining member 4 also functions to apply the product with the hair strands, which are then covered from two sides. For example, the retaining member 4 is a mirror image of the container 27 with respect to the point on the connecting strip 3 or with respect to the axis perpendicular to the axis 19.

The apparatus is integrally formed, for example, by casting a flexible and flexible material. In one variant, the device may have a number of parts, in which case the connecting element 3 may be a hinge. Even in this variant, the tooth 25 can be attached to the application means 2 and / or the retaining member 4. The teeth can then consist of artificial or natural bristles, which for example are attached with an adhesive to the application means 2.

In the claims and the description, it is to be understood that the expression "having one" has the same meaning as "having at least one" unless otherwise indicated.

The device according to the invention is particularly suitable for self-applying a dyed product onto several strands of hair. Further, by the device for applying the highlight of the hair product according to the present invention, even if the product is like a dough, it is uniformly immersed without depositing lumps on the hair strands, and the width of the highlight formed in this way is easily reshaped so that the entire hair A uniform result can be obtained over the head.
