Description

The present invention is a device for confining cosmetic ingredients on a quantity of keratin fibers,
Move relative to each other between an open position where an amount of keratin fibers can be placed in place and a closed position for confining an amount of keratin fibers in an intermediate space formed between the members. With two members that can
It relates to a type of device in which one of the movable members comprises a rigid part and a deformable part adapted to be applied over an amount of keratin fibers to match the shape of an amount of keratin fibers.

  In particular, in the sense of the present invention, “beauty ingredient” means a product as defined in the Council Directive 93/35 EEC dated 14 June 1993.

  The cosmetic ingredient is advantageously a composition for continuously deforming keratin fibers and in particular the hair, such as a reducing composition for perming the hair.

  The most common technique for persistently deforming hair is to apply a composition containing a suitable reducing agent, then rinse the hair thus treated and then apply pre-tension, for example using curlers. This is a technique for applying an oxidizing composition to the obtained hair and finally giving the hair the necessary shape.

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

  The new shapes added to the hair by chemical treatment as described above are highly durable, especially resistant to cleaning action with water or shampoo, unlike simple and temporary conventional deformation techniques like hair sets .

  After the curler is placed at a predetermined position on the hair, the above-mentioned type of device attached to the curler so as to cover the hair while applying the permanent component is disclosed in Patent Document 1, Patent Document 2, and Patent Document 3, for example. Known from.

  Such a device is not fully satisfactory. These devices have a wide opening to the outside so that some of the cosmetic ingredients can escape, thus reducing the efficiency of the perm method.

  Therefore, a large amount of reducing composition needs to be applied to the hair to obtain the required effect, which can be uncomfortable for the user.

  1 to 6 show a first cosmetic treatment kit 10 according to the present invention.

  This first kit 10 is especially adapted for treating a group of keratin fibers 11, in particular a hair tress, as shown in FIGS. 2 and 3.

  The treatment is performed using the kit 10 according to the invention by applying the cosmetic ingredients to the hair tress and optionally confining the beauty ingredients in the tress by heating.

  Hair treatment includes hair care or conditioning, hair retention or setting or perm, temporary, semi-permanent, or permanent hair coloring, straightening, or smoothing.

  According to a particular example, the cosmetic ingredient is a continuous hair deformation composition.

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

  As shown in FIG. 1, kit 10 includes a keratin fiber tensioning assembly 12 and a containment device 14 according to the present invention.

  The tension assembly 12 includes a tensioning portion 16 and conveniently includes a heating means 18 and a portion 20 for electrically connecting the heating means 18.

  The tension portion 16 has a generally elongated shape along the long axis A-A '.

  This portion 16 may be cylindrical, for example, and may form a roller or rod that forms a curler.

  In this example, the heating means 18 is fixed to the tension portion 16. The heating means 18 is conveniently arranged in a cavity formed in the tension part 16.

  In one alternative embodiment (not shown), the heating means is supported by the confinement device 14.

  In the example shown in FIGS. 1 and 6, the connecting portion 20 includes an electric wire 22 that is adapted to be connected to a current source, and a connection head 24 that is inserted into and removed from the heating means 18.

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

  As an alternative embodiment, the electrical wire 22 is connected to the heating means 18 so that it cannot be removed.

  For example, the electrical connection head 24 is inserted into one of the longitudinal ends of the pulling portion 16.

  The tension portion 16 includes an outer surface 21 that forms keratin fibers and is applied to the keratin fibers 11. When the keratin fiber 11 is wound around the tension part, the tension part 16 forms a certain amount of keratin fiber 11.

  As shown in FIG. 5, the confinement device 14 includes two members 28A, 28B that freely move relative to each other to form a clip, and the two members 28A, 28B place the keratin fibers in place. It can be moved between an open position where it can be closed and a closed position where a certain amount of keratin fibers can be trapped.

  Each movable member 28A, 28B comprises a rigid portion 30A, 30B that forms a support and a deformable portion 32A, 32B formed by a flexible half shell to contain and contain a quantity of keratin fibers. .

  In the example shown in FIGS. 1-6, device 14 also includes means 36 for hinged movable members 28A, 28B to each other.

  The rigid portions 30 </ b> A and 30 </ b> B include an operation area 38 and a support area 40, and the operation area 38 and the support area 40 are disposed on each side of the joint means 36.

  The support regions 40 of the respective rigid portions 30A and 30B are arranged so as to face each other by a certain distance.

  Each operation area 38 in this example includes a lug 42 protruding laterally from the support area 40.

  In this example, the support area 40 and the operating area 38 are made of a single member of the same material.

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

  The outer shape of the central opening 46 is designed to accommodate the tension portion 16 and surround the tension portion 16.

  In the example shown in FIG. 1, the frame 44 extends substantially in one plane. The frame 44 is conveniently substantially rectangular. The frame 44 comprises two longitudinal struts 48A, 48B substantially parallel to the axis B-B 'connected to each other at the ends of the struts 48A, 48B via cross members 50A, 50B.

  The operation unit 38 protrudes from the support column 48 </ b> B in the support region 40. In the example shown in FIG. 1, the lengths of the cross members 50A, 50B perpendicular to the line B-B 'are shorter than the lengths of the columns 48A, 48B measured parallel to the axis B-B'.

  The first cross member 50 </ b> A extends substantially in the plane of the frame 44. The second cross member 50B also includes a convex central region 52 that defines a notch 54 that opens toward the opposite rigid portions 30A, 30B.

  The joint means 36 includes joint tabs 60A and 60B fixed to the first rigid portion 30A and the second rigid portion 30B, a joint shaft 62 that connects the tabs 60 to each other, and the members 28A and 28B in the closed position. And an elastic operating portion 64 to be arranged.

  The tabs 60A, 60B protrude from each region 38 that moves the rigid portions 30A, 30B toward each other. The tabs 60A, 60B are conveniently made of the same material as the operating area 38.

  The hinge shaft intersects the tabs 60A and 60B and connects the tabs 60A and 60B to each other. The hinge shaft extends substantially parallel to the axis B-B ′ extending from the support region 40.

  Therefore, the rigid portions 30A and 30B are moved with respect to each other, the support regions 40 are arranged at a distance from each other, and the operation regions 38 are located close to each other, and the support regions 40 are mutually connected. The confinement device 14 can be moved between a closed position that is located nearby and where the operating areas 38 are spaced apart from each other.

  The elastic actuating portion 64 may be formed of, for example, a spring that can actuate the rigid portions 30A, 30B and place it in the closed position of the device 14.

  In this example, the operating portion 64 is formed from a spring added between the operation areas 38.

  In a variant embodiment (not shown), the actuating part 64 is formed by an elastic strip made of the same material as the at least one operating region 38.

  The deformable portions 32A, 32B in this example are formed by flexible half shells 70A, 70B that define an intermediate containment space 72 for a quantity of keratin fibers 11 when the device 14 is in the closed position. .

  In the example shown in FIGS. 4 and 5, each half shell 70 </ b> A, 70 </ b> B includes a peripheral seal 74 and a central wall 76 that contacts and conforms to a certain amount of keratin fibers 11.

  The peripheral seal 74 has a shape complementary to the frame 44 to which it is fixed. The peripheral seal 74 includes a solid bead 78 that forms a mounting surface 80 to the frame 44 and an opposing surface 82 that is applied over the seals 74 of the opposite half shells 70B, 70A. Peripheral seal 74 also advantageously includes ribs 83 that protrude upward from surface 80 and are inserted into corresponding grooves (not shown) formed in frame 44.

  The working surface 82 is substantially planar, so that a seal is formed when applied to the working surface 82 of the opposing half shells 70B, 70A.

  The peripheral seal 74 includes two longitudinal portions 84A, 84B that are applied to the struts 48A, 48B of the frame 44 and two lateral portions 86A, 86B that are applied over the corresponding cross members 50A, 50B.

  In the closed position, the first lateral portion 86A of the half shells 70A, 70B extends substantially in one plane and thus over its entire length on the corresponding region 86A of the opposing half shells 70B, 70A. Can be applied. The second lateral portion 86B includes a concave central portion that fits into the notch 54 and forms a recess 90 in which the electrical connection head 24 of the tension assembly 12 fits complementarily.

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

  The deformable wall 76 is formed from a thin stretchable membrane. “Extensible membrane” means a membrane that can be elastically and reversibly deformed, for example by increasing the total area by reducing the thickness.

  The membrane that forms the wall 76 is thinner than the bead 78 that forms the seal 74 and is advantageously one-half the thickness of the bead 78.

  The membrane is made of a material that can be elastically and reversibly stretched without causing significant plastic strain.

  Therefore, the surface area of the wall 76 is wide by at least 10%, for example between 10% and 100%, without causing much plastic strain, so as to match the shape of a certain amount of keratin fibers 11 arranged in the intermediate space 72. Can be.

  The stretchable wall 76 membrane is advantageously silicone or natural rubber, EPDM (ethylene propylene diene copolymer), NBR (butadiene and acrylonitrile copolymer), or thermoplastic, particularly TPU, SEBS, SBS, or EVA, etc. Made from a deformable polymer such as an elastomer such as a thermoplastic elastomer such as a flexible thermoplastic.

  In the example shown in FIG. 5, the wall 76 is made of the same material as the peripheral seal 74. Wall 76 extends seal 74 into opening 92.

  As shown in FIG. 4, when the peripheral wall 76 is in the rest position and no external stress is applied to the peripheral wall 76, the peripheral wall 76 has a major axis BB ′ and advantageously facilitates the central region 100. A central region 100 in the form of a cylindrical dome with two lateral grooves 102 is provided for deformation.

  Central region 100 projects outwardly within opening 92 defined by peripheral seal 74. The central region is convex outward.

  The groove 102 extends to each side of the central portion 100. Contrary to the convex shape of the central portion 100, the groove 102 is concave toward the inside.

  At rest, the wall 76 has a substantially Ω-shaped cross-sectional profile in a cross-section relative to the axis B-B ′.

  When the confinement device 14 moves from its open position to its closed position, the half shells 70A, 70B are configured such that the half shells 70A and 70B are spaced apart from each other and one half shell contacts the other half shell. Can move towards each other between configurations.

  Thus, in the open position of the device, the working surfaces 82 of the peripheral seal 74 are at least partially separated from each other, particularly along the two longitudinal portions 84B furthest from the articulation shaft 62.

  Next, the intermediate space 72 is opened, and a certain amount of keratin fiber 11 can be inserted between the movable members 28A and 28B.

  In the closed position of the device 14, the working surface 82 of the peripheral seal 74 is advantageously substantially working surface 82 excluding the indentation 90, which is greater than 75% of the circumference of the working surface 82 as measured all around the seal 74. Are in contact with each other over the entire circumference.

  In this example, the seal 74 is formed by a recess 92 facing the seal 74 into which the electrical connection 20 is inserted, and defines a passage 104 whose shape is complementary to the external shape of the head 24 of this portion 20.

  Accordingly, in the closed position, the half shell 70 is shaped to form a substantially sealed intermediate space 72 when a quantity of keratin fibers 11 is disposed within the intermediate space 72.

  In the present invention, “substantially sealed” means that this space is entirely closed by the seals 74 facing each other or partially closed by the seals 74 facing each other between the half shells 70A, 70B. And is partially closed by the tension assembly 20 arranged to correspond to the insertion passage 104 formed between the seals 74 in complementary portions.

  “Closed” means that a gap that may exist locally between the seals 74 facing each other or between the seal 74 and the tension assembly 20 is less than 2% of the thickness of the seal 74; Conveniently means less than 1%.

  Note that the keratin fibers 11 are partially clamped between the seals 74 to a portion of the periphery of the seal 74.

  In this example, the seals 74 are applied to each other, in particular, along the longitudinal portions 84A, 84B of the seal 74 and on at least one lateral portion 86A perpendicular to the line BB ′. Close.

  In a variant embodiment (not shown), the seals 74 are in contact with each other over the entire circumference of the intermediate space 72. In this case, each seal does not form the opening 104 larger than the gap.

  In the closed position, the seal is compressed by at least 1% of the seal height relative to the seal height in the open position, and advantageously less than 75% of the seal height relative to the seal height in the open position. Is compressed by the amount of.

  In the closed position, the wall 76 can be deformed by reversibly elastically extending so that the groove 102 moves outward and then the wall 76 expands its surface area, which surface area on the tension assembly 20. Depending on the volume defined by the group of keratin fibers alone in the absence of the group of keratin fibers 11 or the tension assembly 20 supported on the substrate.

  Next, the operation of the first kit 10 according to the present invention for treating a group of keratin fibers 11 will be described.

  First, confinement device 14 and tension assembly 12 are supplied separately. When the confinement device 14 is in the closed position, the actuating portion 64 holds the deformable half shells 70A, 70B applied to each other with the peripheral seals 74 in contact.

  A group of keratin fibers 11 to be treated is selected and then wound around the tension part 16. A cosmetic ingredient, conveniently a permanent hair wave composition as described above, is applied to the keratin fibers 11 by, for example, spraying or using an applicator.

  Next, the electrical connection part 20 is connected to the heating means 18 of the tension part 16.

  The operator then grasps the operating area 38 of the containment device 14 between the operator's fingers. The operator moves these operation regions 38 toward each other against the resistance of the elastic actuator 64, and pivots the rigid portions 30A, 30B around the axis 62 away from each other.

  When the rigid portions 30A and 30B are displaced, the flexible half shells 70A and 70B are displaced to move away from each other, and the confinement device 14 has a certain amount of keratin fibers 11 disposed in a predetermined position. Move to the open position.

  Next, the device 14 is moved toward the tension portion 16 to insert the tension portion 16 and the keratin fiber 11 into the intermediate space between the half shells 70A and 70B.

  The operator then presses the tension 16 against the extensible wall 76 of the half shell 70B by inserting the tension 16 into the central opening 46 of the frame 44.

  The operator places the electrical connection 20 in the recess 90 as needed.

  The operator then releases the operation area 38. Under the action of the operating portion 64, the operation regions 38 pivot from each other, the support regions 40 move toward each other, and the peripheral shell 74 of one half shell 70A faces the half shell 70A. It is possible to make contact with the peripheral seal 74.

  During this displacement, the keratin fibers 11 are captured between the seals 74 facing each other along the longitudinal portion 84B. Similarly, the electrical connection 20 is complementarily secured within the passage 104 formed by the recess 90.

  Since the extensible wall 76 is deformable, it is firmly applied over an amount of keratinous fibers 11 formed by the fibers 11 wound on the tension 16, and the central region 100 and possibly its extension. Is arranged outside and the groove 102 is arranged outside.

  Since the peripheral seals 74 are applied to each other substantially over their entire circumference, the peripheral seal 74 clamps the keratin fibers 11 passing through the connection head 74 of the electrical connection 20 and the seal 24 between the peripheral seals 74. To do. Next, the intermediate space 72 formed between the half shells 70 </ b> A and 70 </ b> B in the closed position is closed in a substantially sealed state over the entire circumference of the space 72.

  In this case, the shape of the internal space 72 is substantially complementary to the shape of a certain amount of keratin fibers 11 and the tension part 16 when the tension part 16 is present. This minimizes the amount of gas present around the keratin fibers 11 in the space 72, thus increasing the processing efficiency.

  The heating means 18 is then switched on and the temperature of the keratin fibers 11 is increased between 50 ° C. and 250 ° C., advantageously between 55 ° C. and 150 ° C., in particular between 60 ° C. and 90 ° C.

  In this case, the duration of this heating is between 1 and 2 hours, preferably between 1 and 30 minutes, more preferably between 5 and 20 minutes, ideally between 10 and 15 minutes.

  After the process is complete, the operator moves the operating area 38 again towards each other against the resistance of the actuating portion 64 to release the containment device 14 and remove a quantity of keratin fibers 11 from the space 72.

  An oxidative composition comprising at least one oxidant is applied and the keratin fiber conformation is fixed by oxidation by modifying disulfide bonds.

  Thus, the containment device 14 safely and easily defines a sealed space 72 for cosmetic ingredients even when the electrical connection 20 penetrates the device 14.

  In particular, because there are deformable half-shells 70A, 70B with extensible walls 76, the confinement device 14 can be adapted to a variable amount of keratin fibers 11, which fits the amount of fibers 11 selected, Or when the tension | pulling part 16 exists, it can implement | achieve either by the winding characteristic of these fibers 11 with respect to the tension | pulling part 16, or the shape of the tension | pulling part 16. FIG.

  This result is obtained by performing a very simple, fast and reliable operation using the device 14 which can be easily cleaned between two uses.

  In particular, this reduces the cost of beauty treatment by reducing the time required for the preparation of this treatment.

  A containment device 14 of a second kit 150 according to the present invention is shown in FIGS.

  Unlike device 14 in first kit 10, rigid portions 30 are articulated relative to each other by articulating means 36 formed by membrane hinge 152. Conveniently, the containment device 14 does not have an operating area 38.

  Furthermore, the articulating means 36 does not have a device for moving the containment 14 towards its closed position.

  Unlike the first kit 10, the containment device 14 of the second kit 150 comprises means 154 for holding the device 14 in its closed position.

  In the example shown in FIGS. 7 and 8, the holding means 154 has one end 158 fixed on the first rigid portion 30A and the opposite side of the second rigid portion 30B facing the first rigid portion 30A. At least one movable tab 156 with a free end 160 adapted to engage on the surface of the substrate.

  The tab 156 holds the second rigid portion 30B in a configuration in which the second rigid portion 30B is released and the free end 160 is maintained at a distance from the second rigid portion 30B. In a closed position, the rigid portions 30A, 30B and the half shells 70A, 70B are in a first configuration between being maintained inserted between the free end 160 of the tab 156 and the associated end 158. It can pivot about a fixed end 158 of the tab 156 relative to the rigid portion 30A.

  In one alternative embodiment shown in FIG. 9, the retaining means 154 includes a click fit tab 166 secured to the first rigid portion 30A. The rigid portion 30B facing it is provided with a through orifice 168 into which a tab 166 is inserted and held.

  In one alternative embodiment shown in FIG. 10, the peripheral seal 74 of each half shell 70A, 70B includes two parallel lips 180 that define a peripheral groove 182 therebetween. When in the closed position, the lip 180 of each seal 74 is pushed into contact with the lip 180 of the seal 74 facing the seal 74.

  In the alternative embodiment shown in FIG. 11, each seal 74 includes a support rim 184 that protrudes beyond the frame 44. In the closed position, the support rim 184 of the seal 74 of each half shell 70A is applied over the corresponding support rim 184 of the seal 74 of the half shell 70B facing the half shell 70A.

  A third kit 190 according to the present invention is shown in FIG. Unlike the first kit 10, the third kit 190 comprises means 154 for holding the device 14 in its closed position. The holding means 154 includes a clamp lever 192 installed so as to freely move between the operation areas 38.

  The user can move the lever 192 to separate the regions 38 from each other or hold them apart.

  Accordingly, the lever 192 is articulated on the region 38, thereby moving the first rigid portion 30A to the opposite side of the half shell 70A with respect to the joint shaft 62.

  The lever 192 comprises a clamping area 194 and an actuating head 196 that projects from the clamping area 194 into a slit 198 formed in the operating area 38 of the second rigid portion 30B.

  The clamp portion 194 slides on the inclined surface 200 of the operation region 38 of the second rigid portion 30B facing the first rigid portion 30A.

  After the device 14 is placed in its closed position, the user actuates the actuating portion 196 to move the lever 192 toward the actuating shaft 62.

  During this displacement, the clamp 194 slides on the inclined surface 200 and moves the operating region 38 of the first rigid portion 30A away from the operating region 38 of the second rigid portion 30B. Accordingly, the seal 74 facing the half shells 70A and 70B supported by the support region 40 is squeezed.

  A fourth kit 210 according to the present invention is shown in FIGS.

  Unlike the containment device 14 in the first kit 10, each half shell 70A, 70B comprises a hollow body 212 formed by a liner. The hollow body 212 forms a deformable peripheral seal 74 and a deformable wall 76 that are in contact with a pressed amount of keratin fibers.

  The hollow body 212 has a substantially C-shaped cross section. Thus, the hollow body 212 includes a substantially planar outer bulkhead 214 secured to the support region 40, a peripheral bulkhead 215, and a concave inner bulkhead 216 that defines an extensible wall 76 and a seal 74.

  The liner 212 advantageously extrudes the longitudinal portions of the septums 214, 216 and the peripheral septum 215 from a constant cross-sectional die, and then seals the axial end of the circumferential wall 216 to form a compressible internal volume 220. Made by.

  Inner partition 216 has a concave central region that forms deformable wall 76 and a substantially planar peripheral region that forms seal 74.

  The inner partition 216 is maintained at a distance from the outer partition 214, and the seal 74 and the deformable wall 76 are deformable toward the outer partition 214, and in particular a certain amount of keratin fiber 11 is tensioned. Fits a certain amount of keratin fiber 11 shape when supported on the part 16.

  Accordingly, as shown in FIG. 16, each half shell 70A, 70B forms a hollow region having an axis B-B 'that is substantially semi-cylindrical in shape. In the example shown in FIG. 16, the hollow region is opened as a recess 92 at one axial end, and the tension part 16 for the keratin fibers 11 can be inserted.

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

  Therefore, after a group of keratin fibers 11 is formed and, if necessary, disposed around the tension portion 14, the operation regions 38 are moved toward each other to separate the hollow main bodies 212 and open the device 14. A quantity of keratin fibers 11 is then inserted between the hollow bodies 212 and the confinement device 14 is switched to its closed position.

  During this displacement, the inner partition 216 is deformed toward the outer partition 214 so as to fit the volume formed by the keratin fibers 11 and accommodates the keratin fibers.

  The seal 74 of each hollow body 212 remains substantially applied to the opposing seal 74 of the opposing hollow body 212 and is substantially sealed, possibly closed axially by the electrical connection 20. An intermediate space 72 is defined between the seals 74.

  The hollow body 212 is fixed on the support region 40 by, for example, bonding or high temperature force fitting, or low temperature force fitting, or insert molding.

  The operating region 38 and the support region 40 are conveniently formed from a single member, 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 otherwise indicated.
