Description

  The present invention relates to an apparatus for applying hair products for highlighting. The device according to the invention is particularly suitable for applying the hair dye product to the hair bundle by itself.

“Highlight” hair dyeing is a treatment that only partially impregnates the hair into the hair dye product, resulting in a non-uniform color effect upon completion of the treatment and lighter or darker than natural or total shading It is a shading that makes certain movements of the hair stand out.
There are various types of hair dyeing products such as temporary hair dyeing, semi-permanent hair dyeing, and permanent hair dyeing called oxidation.
All of these hair dye products can be creamy, foamy or somewhat viscous liquids. A liquid or gel hair dyeing product can be applied after optionally mixing using a porous means such as foam. However, the most viscous and sticky product is a mixture of bleach and oxidizer in a bowl.

In order to apply these products in the balls, application devices are known which consist of either a comb or a thin brush or a combination of the two. Such devices are described, for example, in the documents FR-A-276488 and US-A-469720.
When using these devices, these devices usually have similar disadvantages, especially by treating the hair from the outside or surface of the hair. The product basically adheres to the surface of the hair bundle and does not adhere much to the inside. The applicator moves continuously from the root to the hair tip with respect to the hair bundle, but during this movement, the user tends to lift the applicator away from the path along the curvature of the head. Shown by experience. For this reason, several hair will leave | separate from an applicator and will return to head hair. Thus, these hairs fail to dye in the case of hair dye products. The results obtained are therefore not satisfactory.
Japanese Patent Application Laid-Open No. 2003-339424 is a publication relating to an application filed before the priority date of the present application and published after the priority date of the present application, and combs the hair with the fingertip regardless of the size of the finger. A hair dyeing brush that can be used is disclosed. The hair dye brush disclosed in the publication is common to the present invention in that it is worn on one finger, but differs from the present invention in that the application means does not include a compressible container.
FR-A-276488 US-A-46972020 JP 2003-339424 A

If the user applies the product himself, it is difficult to operate these devices according to the prior art to highlight the occipital region. This is because these devices are difficult to position accurately when trying to use them for application to hair that is not directly in view.
Furthermore, if a very sticky product is to be applied, it is difficult to extend the product to the full length of the hair bundle using a thin brush.

Document US-2705499 also discloses a scissor-shaped applicator with two branches hinged about a pivot axis. The first branch consists of two side-by-side combs with a pad soaked with the product in between, and the second branch consists of a brush that can abut the pad soaked with the product.
Since these applicators are obtained by assembling a plurality of mechanical parts, they are expensive and complicated to manufacture. Furthermore, the branch hinges of these applicators often interfere with the hair or part of the product blocking the two branch hinges.
US-2705499

Documents US Pat. No. 2,722,706 and DE-2834801 also disclose an applicator comprising a glove or a finger sack, the applicator comprising a dispenser impregnated with the product, the dispenser on the palm or finger ventral side. Be positioned.
While these gloves or finger sacks are made of an impermeable material, the dispenser is made of a material that is permeable to the product, so these applicators must be made of a different material than the dispenser that can be coated with the product. Thus, these applicators also have problems. Furthermore, since the liquid that has soaked into the dispenser tends to drip along the wall of the glove without covering the hair, it is not easy to operate the glove and apply the product to the head yourself. The finger sack presents an additional problem because it can rotate around the finger, particularly while moving longitudinally along the hair bundle.
US-2722706 DE-2834801

The object of the present invention is to overcome the above-mentioned problems by providing a device that facilitates the self-application of hair products for “highlight”. The device of the present invention comprises means for applying a hair treatment product, and the application means is provided with a fixing means so as to be positioned on the fingertip.
In order to improve the fixation around the finger, for example, the finger is pressed against the outer surface of the flat bottom of the application means by the fixing means.

One of the advantages of the device of the present invention is due to the ergonomic nature of the application means with a hand compressible container. The container of the application means can contain a single use product, which can be released when one wall of the container is compressed. This is because the wall can be at least partially compressed so that the height of the container wall relative to the securing means is reduced.
In order to coat the hair bundle, the container can in particular be gradually compressed while being moved longitudinally along the hair bundle from the root to the hair tip. The hair bundle is advantageously impregnated with the product uniformly so that no clumps are formed even if the product is sticky, the width of the highlights made in this way is easy to reproduce and obtains a uniform result over the entire hair It becomes possible.

  If the application means has teeth, these teeth are preferably standing perpendicular to the bottom of the application means, providing a central recess defined by the surface formed by the flank of the plurality of teeth And the central recess forms a container. These teeth are also compressible.

  In order to compress the container and release the in-container product into the hair bundle, the hair bundle is physically sandwiched, for example, between the container opening of the application means and at least one remaining finger of one hand. In this case, the compressive force is applied to the container bottom by at least one finger located on the outer surface of the container bottom in the securing means, and the container is compressed by at least one finger and the other finger in one hand. The With the device of the present invention, suitable results can be obtained even if it is not very dexterous. In a variation, the container may be compressed such that the hair bundle is sandwiched along a wall that defines an opening in which the hair bundle is disposed.

  In a preferred embodiment, the fixing means can be adapted to the diameter of the finger to be fixed. For this purpose, the fixing means has, for example, two tabs that can be connected to each other. In this case, the first tab can be inserted into the hole of the second tab, and one of the tabs has a plurality of steps for securing the first tab to the second tab. Two tabs preferably allow the fixing means to be fixed around the fingertip.

  At least one tab has two arcuate portions so that the finger is not bitten when the securing means is secured around the finger. Two arcuate parts are attached at the position of the application means. Since they are joined, they can be joined together to the second tab. By providing the arcuate portion, the application means is stabilized on the fingernail side to which the fixing means is fixed.

  In order to accurately position the application means ahead of the first joint of the finger around which the fixing means is fixed, the application means further includes a stop on the outer periphery to provide a limit for the finger to be inserted into the fixing means. Is provided.

  In order to reduce manufacturing costs and to facilitate production and packaging, the device of the invention consists of a single element, for example obtained by molding.

  In order to facilitate the compression of the container, it is preferable to use a pressing member that further acts as a support part for arranging the hair bundle opposite to the front surface of the container opening. This pressing member can be fitted to the other finger by a fixing means similar to the fixing means of the application means. In order for the application means and the pressing member to serve the function of guiding a finger fixed around it, the application means is further connected to the pressing member by a connecting element, preferably a flexible strip.

  The application means and the pressing member are simultaneously moved along the hair bundle while sliding from the root to the hair tip in order to cover the hair bundle arranged between them. Here, the connecting means provides a guide for moving these two components simultaneously. Thus, the hair bundle is physically sandwiched between the two fingers of one hand, and the device moves more reliably and straight along the hair bundle. With the device of the present invention, suitable results can be obtained even if it is not very dexterous.

  The holding member engages with the container opening so that the product contained in the container is continuously distributed. Specifically, the pressing member can be folded and stacked on the opening so that the hair bundle is sandwiched between the container opening and the pressing member. Next, pressure is applied to the outer periphery of the container bottom and the outer periphery of the pressing member. The pressure is due to sandwiching between at least two fingers, for example, the thumb and index finger of one hand.

  When the hair bundle is sandwiched between the application means and the pressing member, the application means and / or the pressing means are used to ensure that the hair bundle actually remains between these two members and the hair product is covered over its entire length. The member comprises teeth that are adapted to engage the hair bundle.

  In order to improve the application of the hair product to the hair bundle, the pressing member can be manufactured to form a second application means. In this case, the second application means can also hold some product. These two application means are then pressed against each other from each side of the hair bundle. Therefore, the product soaks into the hair bundle more suitably. For example, the pressing member is a mirror image of the applying unit with the axis orthogonal to the connecting element connecting the pressing member and the applying unit as the axis of symmetry.

The present invention is:
i) an application means capable of holding a quantity of hair product; and ii) at least one fixing means disposed on the application means capable of fixing the application means to at least one finger of one hand. Comprising a device for applying hair products for highlighting,
The securing means comprises at least one elastically deformable tab that can be at least partially fastened around at least one finger, and the applicator means comprises a compressible container, the container in particular comprising the device When the device is moved longitudinally with respect to the hair bundle, the present invention relates to an apparatus characterized in that a certain amount of product can be released in the hair bundle in response to the pressure applied to the container using the hand.

  Advantageously, one wall of the container is compressible in response to a pressure applied at right angles to the bottom where the fixing means are located.

  Also advantageously, one wall of the container is formed by teeth standing perpendicular to the bottom, and a central recess is defined by the surface formed by the collection of the sides of the plurality of teeth. As a variant, one wall of the container forms, for example, a bellows with a shape memory coil spring.

  For example, the fixing means may be adjustable according to the size of at least one finger to be fixed.

  Suitably the securing means may have two tabs that can be connected to each other. In this case, the axes of these tabs may be identical and the tabs may extend in two opposite directions along the axis. The one or more tabs advantageously extend in the plane formed by the bottom of the container.

  According to a particular embodiment of the invention, one tab is attached to the bottom of the container by at least two arcs. In this case, the two arcuate portions may be elastically deformable.

  Advantageously, the securing means may comprise a stop on the outer periphery of the container in order to provide a limit for the fingers to be inserted into the securing means.

  Also advantageously, the device may comprise a holding member that can engage with the container in order to keep the hair bundle in contact with the container so that the hair bundle is coated with the product. In this case, the pressing member can be superimposed on the opening, the hair bundle is sandwiched between the container opening and the pressing member, and the container is pressurized by pressing the container bottom and the pressing member from both sides of the hair bundle. Can be obtained. Optionally, the hold-down member has a plate that is larger than the container opening. As a modification, the pressing member may include teeth. Alternatively, the pressing member may be the same as the application member.

  Advantageously, the pressing member also comprises second fixing means that can be fixed to at least one second finger. In this case, the securing means may comprise at least one elastically deformable tab that can be at least partially fastened around the second finger. Preferably, the fixing means in this case has two elastically deformable tabs that can be connected to each other.

Preferably, the pressing member is connected to the container by a flexible connecting strip.
If the device comprises a flexible strip, the tab or tabs extend perpendicular to the flexible strip.

  The device may preferably consist of a single element, for example obtained by molding.

  The invention will be better understood after reading the following description and examining the accompanying drawings. These are merely examples and do not limit the invention.

FIG. 1 shows a device 1 according to the invention. The apparatus 1 includes an application means 2. The application means 2 has a bottom 12 and a container 27, which is disposed on the inner side surface 26 of the bottom 12. A single quantity of product can be placed in the container 27. Preferably the container 27 is a hand compressible container, and the product contained in the container can be released by compressing at least one of the container walls 28. These walls 28 stand perpendicular to the bottom 12 of the application means 2 and are compressed to reduce the volume defined by the container 27.
When the hair bundle is applied to the opening of the container, the wall 28 adheres a part of the product along the entire length of the hair bundle when the application means 2 is moved in the longitudinal direction with respect to the hair bundle. It is preferable to be gradually compressed so that

  The device 1 comprises at least one fastening means 5 which is fastened to at least one finger 9 of one hand 7. The inner surface 26 is on the opposite side of the outer surface 13. The concept of the inner side surface 26 and the outer side surface 13 is defined with respect to the position of the finger 9 fixed to the applying unit 2 by the fixing unit 5, and the outer side surface 13 corresponds to a surface on the same side as the finger 9. The inner side surface 26 corresponds to a surface on the same side as the container 27 made to come into contact with the hair bundle.

In order to improve the application of the product to the hair bundle, the application means 2 comprises teeth 25 that engage the hair bundle to be coated. The teeth 25 stand vertically on a part or all of the inner surface 26. For example, the teeth 25 are arranged in a plurality of rows, particularly near the edge of the inner surface 26. In FIG. 1, the row of teeth 25 forms a wall 28 and is compressible.
The teeth 25 preferably stand perpendicular to the lower surface 26. The height of the teeth relative to the plane defined by the lower surface 26 varies. In particular, if the teeth 25 are arranged partly or entirely around the circumference of the face, the central recess is defined by these teeth. The central recess may be defined by a surface formed by the side surfaces of the plurality of teeth. In this case, the recess corresponds to the region of the inner side surface 26 having the shortest teeth and forms a container 27. The presence of the teeth 25 makes it possible to accommodate a single quantity of the product, especially when the product is sticky.

  In the variant of FIG. 2, the container 27 is defined by a continuous wall 28 formed beyond the edge of the bottom 12. Thus, in this case, the teeth are connected to each other at the base. As a result, the edge defining the opening of the container 27 is jagged. The jagged portion is formed, for example, partially on the edge of the wall, and the portion of the edge is a portion located on an axis along which the hair bundle is aligned when the hair bundle is disposed with respect to the applying means 2. In this case, the tooth 25 functions as a comb.

For example, the container 27 has an open cylindrical shape or parallelepiped shape. In all cases, the hair bundle is applied to the opening of the container 27 as shown in FIG.
The pressure is preferably applied with a hand at right angles to the outer surface 13 of the bottom 12. The pressurization is obtained by compression, for example. In FIG. 3 (a), in order to compress the container 27 and release the product to the hair bundle, the finger 9 to which the fixing means 5 is fixed applies pressure from the outer surface 13, and at least one second finger 8. Cooperates with the finger 9 in which the fixing means 5 is fitted.
The second finger 8 is placed opposite the opening of the container, and the hair bundle to be covered is placed between the second finger 8 and the opening of the container 27. Preferably, the hand of the second finger 8 is the same as the hand of the finger in which the fixing means 5 is fitted. The fingers used for highlighting are, for example, the index finger and the thumb.
The wall 28 of the container 27 can be compressed by manual pressure. Furthermore, the wall has shape memory properties. In other words, after the first compression, when the pressure is released, the wall rises and the container 27 returns to the maximum content. Thereafter, the container can be refilled with a quantity of product to be applied to another hair bundle.

  The container 27 is made of a flexible material, for example. A flexible material having a hardness of 30 to 150 Shore A, preferably 60 Shore A, is preferably used. The material used is selected, for example, from SEBS polymers or injection-mouldable thermoplastic rubbers such as Santoprene® (available from Santoprene: Monsanto) or more generally thermoplastic materials .

  The walls of the container 27 comprise bellows elements that can be shrunk on top of each other as shown in FIG. 3 (b). To return to the initial shape, the wall may be provided with a coil spring, as shown in FIG. 3 (c), for example as a rib-like portion of the wall. The coil spring also defines a suitable fold line for the wall 28.

According to the preferred embodiment shown in FIG. 4, the pressing member engages directly with the opening of the container 27, and the hair bundle to be covered is arranged between the pressing member 4 and the opening. In this embodiment, each of the applying means 2 and the pressing member 4 includes fixing means 5 and 6. These fixing means are designed to be fixed to at least two user fingers.
In the preferred embodiment shown in FIG. 4, the device 1 is then secured to the finger of the user's one hand 7. The application means 2 is arranged on the thumb 9 of the hand 7 by the first fixing means 5, and then the pressing member 4 is arranged on the index finger 8 of the same hand 7 by the second fixing means 6.
The holding member 4 is designed to improve the compression of the wall 28. This is because the contact is fixed by the member, and the wall 28 can be pushed more firmly between the contacts than when directly pressed by the belly of the second finger 8. Accordingly, the opening of the container 27 can be made wider than the surface area of the belly of the second finger 8. Therefore, it becomes easy to highlight with a width wider than the width of the finger.

The fixing means 5 and 6 may employ different fixing mechanisms. They are preferably produced in the same way. Various modifications of the fixing device envisaged in the present invention are described only for the fixing means 5. An alternative embodiment of the fixing means 6 can be inferred from an alternative embodiment of the fixing means 5, and the pressing member 4 needs to be used instead of the application means 2 as necessary.
In the first variant, the fixing means 5 has a first tab 10 which is adapted to engage with the second tab 11. These tabs 10 and 11 form a strap which can be connected to each other. For example, these tabs 10 and 11 are defined as an extension of the bottom 12 formed by the application means 2. In this case, these tabs extend in opposite directions. These tabs are designed to have some flexibility and can be bent in the direction of each other on the outer surface 13 of the bottom 12. In order to connect them, each tab is provided with complementary connecting means.
The fixing means 5 is preferably adjustable in accordance with the size of the finger to be fixed, for example, the diameter of the finger. For example, the first tab 10 has a plurality of holes such as 14, and the projections 15 of the second tab can be inserted into the holes. Preferably, the second tab 11 also has a plurality of protrusions such as 15. Thus, the two tabs 10 and 11 have adjusting means.
The protrusion 15 as shown in FIG. 1 is inserted into the hole 14 by force.

In one variant, the projection 15 is inserted without applying force. In this case, the shape of the hole 14 is as shown in FIG. 2 and corresponds to two circular openings 14 ′ and 14 ″ connected to each other by the neck 16. The diameters of the circular openings 14 'and 14''are different. Therefore, the protrusion 15 can be inserted into the opening 14 ′ having a large diameter, and then slid through the neck 16 to be moved to the opening 14 ″ having a small diameter so as not to come off. When considering the hole 14 of the first tab 10, it is preferable that the hole 14 ″ having a smaller diameter is further away from the coating means 2. This is because the tabs tend to move away from each other as long as they are connected, and the protrusions 15 remain fixed in the small diameter openings 14 ''. .
In the modification shown in FIG. 2, the second tab 11 has an elongated tubular shape. The projection 15 corresponds to a chamfered collar, and the base 17 of the collar is larger in diameter than the tube 11 and protrudes from the periphery of the tube. The chamfering is performed so that the base portion 17 is closer to the coating means 2. In this case, the diameter of the large opening 14 ′ is larger than the diameter of the base 17, and the diameter of the small opening 14 ″ is larger than the diameter of the tube 11 but smaller than the diameter of the base 17.

  In another variant (not shown), the fixing means 5 is in the form of a finger sack into which at least one finger can be inserted. In this case, the finger sack is formed as an extension of the outer surface 13 of the application means 2.

  In another variant (not shown), the fixing means 5 has only one tab that can be engaged with complementary means arranged on the outer surface of the application means 2.

Tabs 10 and 11 preferably extend in two opposite directions along the same axis 18.
According to a first embodiment shown in FIG. 1, the tab extends along an axis 18 that intersects the application means 2. Preferably, the outer surface 13 of the bottom 12 is positioned before the first joint of the finger. This positioning allows more accurate application of the hair product.

  In order to prevent the finger from being bitten by the fixing means 5, the tab is divided into two arcs. For example, as shown in FIG. 5, the tab 10 has a first arcuate portion 20 and a second arcuate portion 21. The two arcuate portions 20 and 21 branch off from the portion where the tab connecting means (in this case the hole 14) are provided and are attached to the application means 2 at two separate points. For example, there may be no gap between the arcuate portions 20 and 21, in which case a tab 10 located closer to the application means will be provided, and the connection means will be thinner.

When the application means is connected to the pressing member by the connecting element 3, as shown in FIG. 5, the first arcuate portion 20 is connected to the outer periphery of the bottom 12 of the application means 2, and the second arcuate portion 21 is It is directly connected to the connecting element 3.
Similarly, in the configuration in which the second tab 11 has two arc-shaped portions 22 and 23, these arc-shaped portions are also connected in the same manner as described above, and have the same contour as the circular shape of the arc-shaped portions 20 and 21. Thus, the segment 29 is formed to extend along the diameter of the circle, and the tabs 10 and 11 extend radially outwardly of the circle 29 at right angles to the segment 29. The division part 29 is arrange | positioned on the axis | shaft of the finger | toe to which the application means 2 is fixed, and a tab surrounds the finger | toe so that it may be connected by the back side of a corresponding hand. The application means 2 is disposed on the division part 29. For example, the application means 2 is disposed at one end of the section 29 (FIG. 5).

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

  In order to improve the fixing position of the finger with respect to the applying means 2, the fixing means 5 includes a stop portion 24 as shown in FIG. In particular, the stop portion 24 preferably stands at a right angle to the outer surface 13 of the bottom portion 12, and is provided at the edge of the outer surface 13, for example.

  The bottom 12 may be rectangular or elliptical, for example. In this case, the stop portion 24 may be linear or curved, so that it is substantially U-shaped as seen above and the finger abuts against the U-shaped depression.

  The connecting element 3 is, for example, a connecting strip extending along the axis 19 between the application means 2 and the pressing member 4. Thus, the tab axis 18 is orthogonal to the axis 19, for example. According to a second embodiment shown in FIG. 5, the tab axis 18 intersects the connecting element 3. According to the second embodiment, it is possible to fix around the fingertip.

  In the second embodiment, the pressing member 4 includes a flat plate having substantially the same shape as the opening of the container 27. In the embodiment of FIG. 5, the plate is circular and has a diameter slightly larger than the diameter of the container 27 opening. Therefore, if the hair bundle is held by the pressing member 4, the outer periphery of the opening of the container 27 can be pressed against the plate. By pressing, i.e. pushing two fingers in the direction of each other, the wall of the container can be compressed between the bottom 12 and the plate. A cut is made in the outer periphery of the opening so that the product is released when the container wall is gradually compressed.

  In one modification, the pressing member 4 has a surface curved inward so as to cover the finger to be fixed more closely. Since the index finger does not naturally overlap with the thumb in parallel, it is possible to assist the parallel arrangement of the pressing member 4 with respect to the application means 2 by curving the surface in contact with the finger inwardly.

  Furthermore, the pressing member 4 may also have teeth such as 25. In this case, the teeth may stand substantially perpendicular to the plate. For example, the hair bundle is passed between the teeth of the pressing member 4 and the teeth of the applying means 2.

  In one modification, the shape of the pressing member 4 may be the same as the shape of the container 27. In this case, the pressing member 4 also functions to apply the product to the hair bundle, so that the hair bundle is covered from both sides. For example, the pressing member 4 is a mirror image of the container 27 with the axis orthogonal to the connecting strip 3 or the axis orthogonal to the axis 19 as the axis of symmetry.

  Preferably, the device consists of a single element, for example obtained by molding flexible and soft materials. As a variant, the device may consist of a plurality of parts, in which case the connecting element 3 may be a hinge. Similarly, in this modification, the teeth 25 may be attached to the application means 2 and / or the pressing member 4. At this time, the teeth 25 can be made of synthetic or natural hairs, which are for example glued to the application means 2.

  Unless otherwise specified, the expressions “comprising”, “having”, “having”, and “having at least” include “at least one”, “having at least one”, and “including at least one”. Is understood to be synonymous.
