Description

DEVICE FOR CONFINEMENT OF A COSMETIC PRODUCT ON A VOLUME OF KERATIN FIBERS, KIT AND ASSOCIATED METHOD}

The present invention relates to an apparatus for limiting a cosmetic product onto a volume of keratinous fibers, the apparatus comprising:

Two movable members, the two movable members having an open position where the constant volume of keratin fibers can be located and an intermediate space formed between the two members of the constant volume keratin fibers Can move relative to each other, between closed positions to restrict

One of the movable members includes a rigid portion and a deformable portion adapted to be pressed onto the volume of keratin fibers to match the shape of the volume of keratin fibers.

"Beauty product" in the context of the present invention means, in particular, a product as defined in "Directive 93/35 EEC of the Council" of 14 June 1993.

The cosmetic product is preferably a composition for permanent modification of keratinous fibers, in particular hair, for example a reducing composition for hair pumps.

The most common technique for obtaining permanent hair deformation is by applying a composition comprising a suitable reducing agent, rinsing the treated hair and then, for example, using a curler to obtain previously tensioned hair. The oxidizing composition is applied to the hair, to finally give the desired shape to the hair.

This technique can generate wave hair using the permanent hair wave method.

The new shape imparted to the hair by a chemical treatment, such as the one described above, is long lasting and, in contrast to simple classical temporary deformation techniques such as hair setting, is particularly resistant to washing of water or shampoo.

Once the curler has settled on the hair, a device of this type added to the curler to cover the hair during application of the hair perm product is known, for example, from FR 1 430 896, US 2,299,367 and GB 743 128. .

Such a device is not entirely satisfactory. Such devices may have a wide opening towards the outside, which may result in the leakage of some of the cosmetic products, thereby reducing the efficiency of the hair pump method.

Therefore, a higher dose of reducing composition must be applied to the hair in order to achieve the desired effect, which can be offensive to the user.

One object of the present invention is to effectively apply a cosmetic product to a volume of keratin fibers, for example hair, and to limit the cosmetic product onto a volume of keratin fibers in order to increase the efficiency of the cosmetic treatment by the beauty product.

This first kit 10 can be used for the treatment of a group of keratinous fibers 11, in particular a bundle of hair, as can be seen in FIGS. 2 and 3.

The treatment is effected by applying the cosmetic product onto one bundle of hair and by using the kit 10 according to the invention to limit the cosmetic product onto this bundle of hairs, if possible by applying heat.

Hair treatments include care or conditioning of hair, fixation or setting or firming of hair, temporary, semi-permanent or permanent hair staining, straightening or smoothing.

According to one particular embodiment, the cosmetic product is a permanent hair modification composition.

For example, the cosmetic product may be a reducing cosmetic composition adapted to reduce keratin disulfide bonds.

As shown in FIG. 1, the kit 10 comprises a keratinous fiber tensioning assembly 12 and a restriction device 14 according to the invention.

The tensioning assembly 12 comprises a tension section 16, and preferably heating means 18 and portions 20 for electrical connection of such heating means 18.

Tension portion 16 generally has an elongated shape along longitudinal axis A-A '.

This tension section 16 may be cylindrical, for example, and forms a roller or rod forming a curler.

In this embodiment, the heating means 18 is fixed to the tension section 16. They are preferably arranged in cavities formed in this part.

In one variant (not shown), the heating means is involved in the limiting device 14.

In the embodiment shown in FIGS. 1 and 6, the connection part 20 comprises a wire 22 adapted to be connected to a current source and a connection head 24 adapted to be fitted into the heating means 18, which is to be removed. Can be.

In this embodiment, the head 24 can be removed from the heating means 18 and the tension section 16.

As a variant, the wire 22 is permanently connected to the heating means 18.

For example, the electrical connection head 24 fits into one longitudinal end of the tension portion 16.

The tension section 16 includes an outer side 21 that forms the shape of keratinous fibers, onto which the keratinous fibers 11 are applied. When the keratin fibers 11 are wound on the tension section, the tension section 16 defines a volume of keratin fibers 11.

As shown in Fig. 5, the restricting device 14 comprises two members 28A and 28B which are free to move relative to each other and form a clip, which two members 28A and 28B are made of keratinous fibers. It can be manipulated between an open position that allows for positioning and a closed position where a volume of keratin fibers can be restricted.

Each movable member 28A, 28B is formed of a rigid portion 30A, 30B forming a support, and a flexible half-shell that includes a variable volume of keratinous fibers 32A, 32B).

In the embodiment shown in FIGS. 1 to 6, the device 14 also comprises hinge means 36 which hingely connect the movable members 28A, 28B to each other.

Each rigid portion 30A, 30B comprises an operating area 38 and a support area 40, which are located on each side of the articulation means 36.

The support regions 40 of the respective rigid portions 30A, 30B are spaced apart from each other while facing each other.

Each operating area 38 in the present embodiment includes a lug 42 that projects laterally from the support area 40.

In the present embodiment, the support area 40 and the operation area 38 are made integrally from the same material.

The support area 40 includes an open frame 44 that defines a central opening 46. As shown in FIG. 1, frame 44 is substantially elongated along axis B-B '.

The contour of the central opening 46 is designed to include the tension portion 16 and to surround the tension portion 16.

In the embodiment shown in FIG. 1, the frame 44 extends substantially planar. It is preferably substantially rectangular in shape. This frame 44 comprises two longitudinal uprights 48A, 48B that are substantially parallel to the axis B-B ', which are at each end through transverse cross-pieces 50A, 50B. It is connected.

The operation region 38 protrudes from the upright portion 48B of the support region 40. In the embodiment shown in FIG. 1, the lengths of the cross-pieces 50A, 50B perpendicular to the line B-B 'are uprights 48A, 48B taken in a direction parallel to the axis B-B'. Is less than the length of

The first cross-piece 50A extends substantially in the plane of the frame 44. The second cross-piece 50B also includes a convex central area 52 that defines the notch 54, which is open upwards towards the opposite rigid parts 30A, 30B.

Articulation means (36) are joint tabs (60A, 60B) fixed to first rigid portion (30A) and second rigid portion (30B), articulation axis (62) for connecting tabs 60 with each other, and movable member, respectively. And an elastic actuating portion 64 for bringing 28A and 28B to the closed position.

The tabs 60A, 60B protrude toward each other from the respective regions 38 for operating the rigid body portions 30A, 30B. They are preferably made of the same material as the operating area 38.

Hinge axes connect to each other across tabs 60A and 60B. This hinge axis extends substantially parallel to the axis B-B 'extending from the support region 40.

Thus, the rigid parts 30A and 30B are moved relative to each other so that the support areas 40 are close to each other and the operation area (from the open position where the support areas 40 are spaced apart from each other and the operation area 38 is close to each other). In a closed position in which 38 is spaced apart from each other, it is possible to move the restrictor 14.

The resilient actuator 64 may be formed, for example, of a spring, capable of operating the rigid parts 30A, 30B such that the rigid parts 30A, 30B are in the closed position of the device 14.

In the present embodiment, the operation portion 64 is formed of a spring added between the operation region 38 and the operation region 38.

As a variant (not shown), the actuating portion 64 is formed by an elastic strip made of the same material as at least one of the operating regions 38.

In the present embodiment, the variable portions 32A, 32B are soft half shells 70A, which define an intermediate confined space 72 of a volume of keratinous fibers 11 when the device 14 is in the closed position. 70B).

In the embodiment shown in FIGS. 4 and 5, each half shell 70A, 70B includes a peripheral seal 74 and a central wall 76 to be pressed against a volume of keratinous fibers to match its shape. .

The peripheral seal 74 is complementary to the frame 44 to which the peripheral seal 74 is fixed. Peripheral seal 74 defines a solid bead 78 that defines an attachment face 80 on frame 44 and an opposing face 82 that is pressed onto seal 74 of opposite half shells 70B, 70A. It includes. Preferably, the peripheral seal 74 also includes a rib 83 protruding upward from the surface 80 to be inserted into a corresponding groove (not shown) formed in the frame 44.

The pressing surface 82 is substantially planar so that a seal is formed when pressed against the pressing surface 82 of the opposing half shells 70B and 70A.

Peripheral seal 74 has two longitudinal regions 84A, 84B pressed against uprights 48A, 48B of frame 44, and two pressed on corresponding cross-pieces 50A, 50B. Transverse regions 86A, 86B.

In the closed position, the first transverse region 86A of the half shells 70A, 70B is substantially planar so that it can be pressed over the entire length onto the corresponding region 86A of the opposite half shells 70B, 70A. Extends. The second transverse region 86B comprises a convex center portion which fits into the notch 54 forming the recess 90, and the electrical connection head 24 of the tensioning assembly 12 has such a recess ( 90) will be complementarily fitted.

Peripheral seal 74 defines a central opening 92 that is completely closed by deformable wall 76.

The deformable wall portion 76 is formed of a thin stretchable film. "Extensible film" means a film that can be elastically and reversibly deformed to increase the total area, for example by reducing the thickness.

The film forming the wall portion 76 is thinner than the beads 78 forming the sealing portion 74 and is preferably half the thickness of the bead 78 thickness.

The film is made of a material that can be elastically and reversibly stretched without any substantial plastic stress.

Thus, the surface area of the wall portion 76 increases at least 10% or more, for example 10% to 100%, without any substantial plastic stress, so that the volume of keratin fibers 11 arranged in the intermediate space 72 is increased. Can match the shape.

The film of stretchable wall 76 is preferably a deformable polymer such as silicone or an elastomer such as natural rubber, EPDM (ethylene propylene diene copolymer), NBR (copolymer of butadiene and acrylonitrile) or thermoplastic resin , In particular thermoplastic elastomers, for example TPU, SEBS, SBS, or soft thermoplastics such as EVA.

In the embodiment shown in FIG. 5, the wall portion 76 is made of the same material as the peripheral seal 74. The wall portion 76 extends the seal 74 in the opening 92.

As shown in FIG. 4, when the peripheral wall portion 76 is in a stable position and no external stress is applied, the peripheral wall portion 76 has a central region in the form of a cylindrical dome having a longitudinal axis B-B '. 100, and preferably two side gutters 102 to facilitate deformation of the central region 100.

The central region 100 protrudes outward in the opening 92 defined by the peripheral seal 74. The central region 100 is convex outward.

The gutter 102 extends on each side of the central region 100. The gutter 102 is convex inward as opposed to the convex shape of the central region 100.

Thus, when in the stable position, the wall portion 76 has an omega-shaped contour substantially in cross section in the cross section about the axis B-B '.

When the restricting device 14 moves from the open position to the closed position, the half shells 70A and 70B can move toward each other between a configuration that is spaced from each other and a configuration in which one shell is pressed against the other shell.

Thus, in the open position of the device, the pressing surfaces 82 of the peripheral seal 74 are at least partially separated from each other, especially along the two longitudinal regions 84B farthest away from the articulation axis 62. .

The intermediate space 72 is then open to allow insertion of a volume of keratinous fibers 11 between the movable members 28A, 28B.

In the closed position of the device 14, the pressing surface 82 of the peripheral seal 74 is substantially around the entire circumference except for the recess 90, preferably around the entire circumference of the seal 74. When measured, they are pressed against each other over 75% of the outer periphery.

In this embodiment the seal 74 defines a passageway 104 formed by opposing recesses 92 into which the electrical connection 20 is inserted, which is the outer part of the head 24 of the electrical connection 20. It has a shape complementary to the shape of.

Thus, in the closed position, the half shell 70 is positioned to form a substantially sealed intermediate space 72 when a volume of keratin fibers 11 are located in the intermediate space 72.

For the purposes of the present invention, " substantially sealed " means that this space is partially and completely between the half shells 70A, 70B, by the opposing seal 74, or by the opposing seal 74. Complementary means that it is partially closed by a tensioning assembly 20 disposed in a manner corresponding to the insertion passage 104 formed between the seal 74 and the seal 74.

"Closed" means that a gap that may exist locally between opposing seals 74 or between seal 74 and tensioning assembly 20 is less than 2% of the thickness of seal 74, preferably Means less than 1%.

It should be noted that the keratinous fibers 11 are partially clamped around a portion of the outer circumference of the seal 74 between the seal 74 and the seal 74.

The seals 74 in this embodiment are in particular mutually along the longitudinal regions 84A, 84B of the seal 74 and on at least one transverse region 86A perpendicular to the line B-B '. The intermediate space 72 is closed by being pressed against.

In one variant (not shown), the seals 74 are pressed against each other around the entire circumference of the intermediate space 72. In this case, the seal 74 does not form an opening 104 larger than the gap therebetween.

In the closed position the seal is compressed at least 1% in height relative to the height in the open position, preferably at least 75% in height relative to the height of the open position.

In the closed position the wall 76 is deformable by the outward movement of the gutter 102 and then by the reversible elastic elongation of the wall 76 so that a constant volume of support supported on the tensioning assembly 20 can be achieved. The surface area can be increased with the volume defined by the keratinous fibers 11 or by only a constant volume of the keratinous fibers without the tensioning assembly 20.

The operation of the first kit 10 for the treatment of a volume of keratinous fibers 11 will now be described in accordance with the present invention.

Firstly, the restricting device 14 and the tensioning assembly 12 are supplied separately. The restrictor 14 is in the closed position, in which position the deformable half shells 70A, 70B are pressed against each other by the actuating portion 64 with the peripheral seal 74 in contact with each other. do.

The bundle of keratinous fibers 11 to be treated is selected and then wound around the tension section 16. Thereafter, a cosmetic product, preferably a permanent hair wave composition as described above, is applied to the keratinous fibers 11, for example using a spray or applicator.

The electrical connection 20 is then connected to the heating means 18 of the tension 16.

The operator then grips the operating area 38 of the restricting device 14 between his fingers. The operator moves these operating regions 38 against each other against the resistive force of the elastic actuating portion 64 to pivot the rigid portions 30A, 30B about the axis 62 so as to be spaced apart from each other.

Due to the positional change of the rigid parts 30A and 30B, the soft half shells 70A and 70B are shifted so as to move in a direction away from each other, and the restrictor 14 places the keratin fibers 11 of a certain volume in place. Moved to the open position to be held.

The device 14 is then moved towards the tension section 16 so that the tension section 16 and the keratin fibers 11 are inserted into the intermediate space between the half shells 70A, 70B.

The operator then presses the tension portion 16 against the extendable wall portion 76 of the half shell 70B by inserting it through the central opening 46 of the frame 44.

If necessary, the operator places the electrical connection 20 in the recess 90.

The operator then releases the operating area 38. Under the influence of the actuating portion 64, the operating region 38 pivots away from each other and the support region 40 moves towards each other such that the peripheral seal 74 of one half shell 70A faces the other. Can be pressed onto the peripheral seal 74 of the half shell 70B.

During this positional change, the keratinous fibers 11 are trapped between the opposing seals 74 along the longitudinal region 84B. The electrical connection 20 is likewise secured in a complementary manner to the passageway 104 formed by the recess 90.

Since the stretchable wall portion 76 is deformable, the stretchable wall portion 76 is firmly pressed onto a predetermined volume of keratinous fibers 11 by the keratinous fibers 11 wound on the tension portion 16. The central region 100 is disposed outwardly and possibly extended, and the gutter 102 is disposed outwardly.

Since the peripheral seals 74 are pressed against each other about substantially the entire circumference, the peripheral seals 74 pass in between, passing through the connection head 24 and the seals 74 of the electrical connection 20. The keratinous fibers 11 are clamped. Thereafter, the intermediate space 72 formed between the half shells 70A, 70B in the closed position is closed in a substantially sealed manner around the entire outer circumference of this space 72.

Then, the shape of the inner space 72, if there is only one, is substantially complementary to the shape of the keratin fibers 11 and the tension portion 16 of a certain volume. This minimizes the amount of gas present around the keratinous fibers 11 in the space 72 and thus increases processing efficiency.

Thereafter, the heating means 18 is turned on to raise the temperature of the keratinous fibers 11 to 50 ° C to 250 ° C, preferably 55 ° C to 150 ° C, more preferably 60 ° C to 90 ° C.

The duration of this heating is then 1 minute to 2 hours, preferably 1 minute to 30 minutes, more preferably 5 minutes to 20 minutes, ideally 10 minutes to 15 minutes.

When the processing is finished, the operator moves the operation area 38 back toward each other against the resistive force of the operation part 64, opening the restrictor 14 and opening the volume of keratin fibers 11 in the space 72. Take it out).

Then, an oxidizing composition containing at least one oxidant is applied, and the disulfide bonds are reformed by oxidation to fix the structure of the keratinous fibers.

Therefore, even when the electrical connection 20 passes through the restricting device 14, the restricting device 14 safely and simply defines a sealed space 72 for the cosmetic product.

Since deformable half shells 70A, 70B are provided, in particular comprising stretchable wall portions 76, the restricting device 14 is tensioned if the amount of selected keratin fibers 11, or tension portions 16, is present. The winding of this keratinous fiber 11 on the part 16 may conform to a variable volume of keratinous fiber 11, which may vary depending on the nature or shape of the tension part 16.

With the device 14 which can be easily cleaned after use, this result is achieved through a very simple, quick and reliable operation.

In particular, this reduces the cost of such treatment by reducing the time needed for preparation of the cosmetic treatment.

7-9 show the limiting device 14 of the second kit 150 according to the invention.

Unlike the device 14 of the first kit 10, the rigid parts 30 are connected to each other by articulating means 36 formed by the film hinge 152. Preferably, the limiting device 14 does not have an operating area 38.

Furthermore, the articulation means 36 do not have a device for actuating the restricting device 14 towards the closed position.

Unlike the first kit 10, the limiting device 14 of the second kit 150 includes means 154 for holding the device 14 in the closed position.

In the embodiment shown in FIGS. 7 and 8, the retaining means 154 engages on one end 158 fixed on the first rigid body 30A and on the opposite surface of the opposing second rigid body 30B. It includes at least one movable tab 156 that includes a free end 160 that is intended to be retracted.

The tab 160 has a configuration in which the second rigid body portion 30B is released and the free end 160 is kept spaced apart from the second rigid body portion 30B, and the rigid body portions 30A and 30B and the half shell 70A, Between the configuration in which 70B remains inserted between the free end 160 and the associated end 158 of the tab 160 in the closed position, around the end 158 fixed with respect to the first rigid portion 30A. Can be pivoted.

In one variant shown in FIG. 9, the retaining means 154 comprises a click-fit tab 166 secured to the first rigid portion 30A. Opposing rigid portion 30B includes through orifice 168 into which tab 166 is inserted and held.

In one variant shown in FIG. 10, the peripheral seal 74 of each half shell 70A, 70B includes two parallel lips 180, the lips having a peripheral groove between them ( 182). When in the closed position, the lip 180 of each seal 74 is pressed to contact the lip 180 of the opposing seal 74.

In the variant shown in FIG. 11, each seal 74 includes a bearing rim 184 that projects beyond the frame 44. In the closed position, the bearing rim 184 of the seal 74 of each half shell 70A is pressed onto the corresponding bearing rim 184 of the seal 74 of the opposing half shell 70B.

12 shows a third kit 190 according to the present invention. Unlike the first kit 10, the second kit 190 includes retaining means 154 for holding the device 14 in the closed position. The holding means 154 comprises a clamping lever 192 which is installed to move freely between the operating region 38 and the operating region 38.

The user can move the lever 192 to separate and hold the manipulation area 38.

Thus, the lever 192 is articulated on the area 38 for manipulating the first rigid portion 30A, opposite the half shell 90A with respect to the articulation axis 62.

The lever 192 includes a clamping region 194 and an articulation head 196, which articulation head 196 is from the clamping region 194 into a slit formed in the operating region 38 of the second rigid portion 30B. It protrudes.

The clamping portion 194 slides on the inclined surface 200 of the operating region 38 of the second rigid body portion 30B opposite the first rigid body portion 30A.

After the device 14 is placed in the closed position, the user operates the actuator 196 to move the lever 192 toward the articulation axis 62.

During this position change, the clamping portion 194 slides on the inclined surface 200 to move the operation region 38 of the first rigid body portion 30A away from the operation region 38 of the second rigid body portion 30B. Let's do it. Thereby, the sealing part 74 which faces the half shell 70A, 70B supported by the support area 40 is correspondingly pressed.

13-16 show a fourth kit 210 according to the present invention.

Unlike the limiting device 14 of the first kit 10, each half shell 70A, 70B includes a hollow body 212 formed by a liner. The hollow body 212 defines a deformable wall 76 and a deformable peripheral seal 74 to be pressed to contact a volume of keratin fibers.

The hollow body 212 has a substantially C-shaped cross section. Thus, the hollow body 212 is a concave inner side defining a substantially planar outer partition 214, a peripheral partition 215, and a stretchable wall portion 76 and a seal 74 secured to the support region 40. Partition 216.

Preferably, the axial end of the peripheral wall 216 to extrude the longitudinal portions of the partitions 214, 216 and the peripheral partition 215 through a constant cross-section die, and subsequently form a compressible internal volume 220. The liner 212 is made by closing it.

The inner partition 216 has a concave central area that forms the deformable wall 76, and a substantially planar peripheral area that forms the seal 74.

The inner partition 216 is kept spaced apart from the outer partition 214 so that the deformable wall 76 and the seal can be deformed towards the outer partition 214, and this outer partition 214 is in particular the tension part 16. When supported on it will match the shape of a volume of keratinous fibers 11.

As shown in FIG. 16, each half shell 70A, 70B forms a hollow region having an axis B-B 'in a substantially semi-cylindrical shape. In the embodiment shown in FIG. 16, the hollow region is opened into the recess 92 at one axial end, allowing insertion of the tension section 16 with respect to the keratinous fibers 11.

The fourth kit 210 functions in a similar manner as the first kit 10.

As such, when a group of keratinous fibers 11 are formed and possibly arranged around the tension portion 14, the operating regions 38 are moved toward each other to move the hollow bodies 212 apart from each other to obtain a device ( 14) to open. Thereafter, a volume of keratinous fibers 11 are inserted between the hollow bodies 212 and the restricting device 14 is changed to the closed position.

During this displacement, the inner partition 216 is deformed toward the outer partition 214 to match and receive the volume formed by the keratinous fibers 11.

The seal 74 of each hollow body 212 remains pressed on the opposing seal 74 of the opposing hollow body 212, defining an intermediate space 72 substantially sealed therebetween. If possible, it is closed axially by the electrical connection 20.

The hollow body 212 is fixed on the support region 40, for example by gluing, hot or cold force fitting, or by insert molding.

The operating area 38 and the support area 40 are preferably integrally formed, for example by injection molding.

The terms "one", "two" and the like should be understood to mean "at least one," "at least two," and the like, unless stated otherwise.
