Abstract

The invention relates to a device for treating the hair, comprising a first and a second movable arm relative to one another between a close configuration of treatment of the hair and a separated configuration of engagement between them of hair to be treated. the first arm carrying a cosmetic product application member adapted to come into contact with the hair in a configuration close to the arms, and the second arm having at least one housing; a pressure element removably disposed in the housing, the pressing element being configured to apply the hair against the application member in close configuration; and a support means on which the pressing member bears in the housing, said support means being configured to allow the pressing member to rock in the housing.

Description

The present invention relates to devices for treating the hair, and more particularly but not exclusively those for shaping the hair, especially those intended for smoothing, curling or embossing the hair. The invention is concerned with devices comprising two arms movable relative to each other, which can take a configuration apart from introducing a lock of hair between them and a close configuration of treatment of the wick, the arms being movable in this configuration close together along the wick. The arms usually bear, in such devices, two heating elements in contact with which the hair is brought during use of the device.

Background

Many devices of this type, sometimes called straighteners, have already been proposed, implementing the application of a hair product on the hair.

WO 2009/078046 discloses an apparatus comprising a seat for receiving a capillary treatment device for dispensing, in use, a hair product. This device is composed of a support material impregnated with the disposable capillary product. The support material comes into contact, in the closed position, with a presser in the form of a roll or a plate.

Application WO 2014/064660 discloses a styling apparatus, comprising a reservoir containing the product to be applied, an applicator member for applying said product to one of the jaws and a steam outlet to the other of the jaws. The applicator member is arranged opposite a counter-support surface. It is also known applications US 2001/0022184 and WO 2012/157865 styling apparatus, comprising heating elements each mounted in a hinged manner on a support means. The invention aims to further improve the devices for applying a hair product on the hair. SUMMARY The object of the invention is thus, according to a first aspect, a device for treating the hair, comprising: a first and a second arm movable relative to each other between a close configuration of treatment of the hair and a spaced configuration of engagement between them hair to treat, the first arm carrying a cosmetic product application member adapted to come into contact with the hair in close configuration of the arms, and the second arm having at least one housing, - a pressure element removably disposed in the housing, the pressing element being configured to apply the hair against the application member in close configuration of the arms, and - a support means on which the pressing element is supported in the housing, the support means being configured to allow the pressing member to switch in the housing.

By "tilting", it should be understood that the pressing element can have a rotational movement about at least one axis, the movement of the pressing element being able to be a more complex movement, with rotation components around several axes. , in particular around or parallel to the longitudinal axis of the pressing element and / or around or parallel to a transverse axis of the housing. The pressing element makes it possible to push the hair on the applicator member to allow effective application of the cosmetic product to the latter.

The tilting of the pressure element makes it possible to exert a more uniform pressure over the entire length of the applicator member and to take account of the manufacturing tolerances. The pressure element is able to adapt to a possible inclination defect of the applicator member, which is particularly useful when the applicator member is removable and can come from various sources.

The fact that the pressure element is removable allows the latter to be cleaned, especially after a long use or when the user wishes to change the cosmetic product to be applied. This also makes it possible to change the pressing element, in particular to replace it with a pressing element of different shape, or of different size, for example to modify the quantity of cosmetic product applied and / or the effect obtained on the hair, in particular by modifying the force with which the pressing element presses on the applicator member. This also makes it possible to access the housing that receives it and to be able to clean it and / or change the means of support. For example, in the case of a spring disposed in the housing, this may allow the latter to change in particular to change the pressure exerted by the pressing element on the applicator member.

Preferably, the pressing element and the applicator member are each of elongated shape along a longitudinal axis Y, and are advantageously of the same length.

More preferably, the pressing element has a bearing surface which is of complementary shape to that of the application surface of the applicator member. For example, the support surface and the application surface are flat on their facing areas.

The support means may be rigid; alternatively, it is elastically deformable. In another variant, the support means comprises an area where the support is rigidly and one or more areas where the support is against one or more elastic return members, which are for example arranged to return the pressing element in a predefined rest position in the absence of mechanical stress by the application member. The elastic return member (s) may be helical or blade springs.

Preferably, the support means comprises, in particular is, a projecting relief at the bottom of the housing and / or the pressing element, in particular in the form of a semi-sphere, or in the form of a substantially conical tooth, or in the form of a half -cylinder oriented perpendicular to the longitudinal axis of the pressing element. Alternatively or additionally, the support means comprises at least one spring, in particular a leaf spring disposed in the housing, for example fixed to the bottom of the housing or attached to the pressing element. For example, the spring or springs constrain the pressure member abutting against the protruding relief.

In particular, the spring or springs can constrain the pressure member in abutment against the raised projection on the bottom of the housing.

The support means may be removable, being for example retained in a recess of the housing when it is in place on the device.

A small extent of the bearing area facilitates tilting.

Preferably, the bearing zone in the housing is substantially located at mid-length of the pressing element.

Alternatively, the support means comprises at least two springs, including two coil springs disposed in the housing, fixed on the bottom of the housing or attached to the pressing element, arranged in particular near the axial ends of the pressing element. The tilting of the pressing element is then possible because of the elastically deformable nature of the springs.

The housing is preferably closed on at least three of its sides and on its bottom. The pressing element is preferably inserted, in particular by sliding, into the housing or extracted from it by a front opening of the latter. The pressure element may comprise at least one relief such as a rib or a groove, cooperating with a complementary relief such as a groove or a rib of a wall facing the device, at least partially defining the housing.

The device may comprise, on the second arm, at least one locking member of the pressing element in the housing, in particular a locking member intended to cooperate with the pressing element, in particular with a corresponding relief of the latter. The locking member makes it possible to prevent the pressing element from coming out unexpectedly. The pressure element may be movable along an axis perpendicular to the application surface, in particular mobile over a maximum driving distance of between 5 mm and 1 mm. For example, the aforementioned grooves are wider than the corresponding ribs, so that the pressure member is movable in translation relative to the ribs, and therefore to the housing, along this axis. The maximum driving stroke can be defined by a relief of the pressing element, coming into contact with the bottom of the housing, and / or by the width of the grooves.

The stroke of the pressure element may in particular be such that during use of the device, the hair to be treated, received between the two arms of the device, are aligned, preferably extend parallel to a direction of movement of the device . The pressure element can form a single piece. The pressure element may have a flat or non-planar bearing surface, in particular having in cross section a non-straight contour, for example convex or concave outwards, in the form of a dihedral or dihedral truncated at its apex. The presser may be of substantially parallelepipedal shape, or be constituted by a roller. The pressure element may have roughness surfaces. Roughness can contribute to the smoothing of hair. The pressure element may be made of a plastic material, in particular polyamide (PA), polyamide glass fiber-reinforced (PAGF), polybutylene terephthalate (PBT), or made of metal.

In a variant, the pressing element is made of a porous material, in particular a material formed of fibers oriented substantially in the same direction, and assembled to form a felt, or of foam. In this case, the pressing element can contribute to the application of the product on both sides of the treated lock, and / or absorb a surplus of product, and / or help to homogenize the application of the product to the hair. The pressing element can be heated. This may allow, at the time of application of the cosmetic product, to fluidify it. The pressure element may have a length of between 70 mm and 110 mm. The applicator member is preferably a porous material, in particular formed by a set of fibers oriented substantially in the same direction and assembled to form a felt, or foam. The applicator member may have a flat or non-planar application surface, in particular having, in cross-section, a non-straight contour side, for example convex or concave towards the outside.

Preferably, the applicator member is soaked with the cosmetic product to be applied to the hair.

In an exemplary embodiment, the pressure element comprises at least one lug engaged in a path defined by the housing receiving the pressing element. This lug defines a tilting axis of the pressing element. This lug can be carried by an elastically deformable tab of the pressing element.

The path is for example defined by a slot or a groove. The lug can be implemented in this way by elastic deformation of the tab which carries it, during assembly of the pressing element in the housing. Preferably, the pressing element comprises two such lugs and two such lugs, which face each other. The pressure element can be biased in the separated position by two springs, including helical compressive working, received at one end in guides and bearing at the other end against a wall of the pressing element. The housing may have a relief, in particular in T-section, and the pressing element may be retained on the housing by abutment reliefs of the pressing element, including beads, under the head of the T.

The comb can be slidably attached to the pressing member, by engagement of at least two ribs separated from each other in corresponding housings of the pressing element, also separated from one another.

These housing can be located on either side of the aforementioned path, in the longitudinal direction. The ribs may be of cylindrical shape of at least partially circular section, and be connected to the rest of the comb by blades which engage in corresponding slots, through which the housing opens outwards. The pressing element may have a U-shaped general section with two opposite uprights and the arrangement of the ribs and housings is preferably such that the comb is pressed against one of the amounts of the pressing element, the base of the teeth of the comb coming to be positioned substantially at the wall connecting the uprights, which also defines the bearing surface for the applicator member.

The comb may have a longitudinal rib bearing against said upright, above the aforementioned blades connecting the cylindrical ribs to the rest of the comb.

The comb also comes frontally in abutment against the amount below said blades.

The comb may comprise at one end an elastically deformable locking tab arranged to snap onto the pressing element at the end of its insertion movement thereon.

The comb may comprise a closing tab which closes the insertion opening at the end of the assembly of the comb on the pressing element.

The comb may include a handle that assists in its placement and removal.

The comb can be introduced or removed in the pressing element only when the latter is in the up position. In particular, the walls defining the receiving housing of the longitudinal ribs separated from the comb can engage in corresponding windows of the underlying structure when the pressing element sinks, these windows being formed in a wall of the housing s' extending between uprights of the pressing element. When the pressing element is depressed, said wall tends to oppose the exit of comb ribs engaged in said housing. The pressing member and the application member may be made of the same material.

More preferably, the applicator member is removable. The applicator member may be mounted on a part serving as a support to form a removable refill. The fact that the applicator member or the refill is removable makes it possible to change the applicator member for reasons of hygiene or when it no longer contains a cosmetic product, or when the user wishes to use another organ application or a different refill, in particular of different shape or containing a different cosmetic product. The applicator member may be supplied with product by a reservoir of the arm which carries it. This tank can be fixed permanently on the arm or be removable, and for example arranged to be put in place and removed at the same time as the application member.

The device may comprise at least two heated plates, heating the hair, respectively arranged on the first and second arms and each in close configuration, apply the hair on the other heated plates. The pressure element is preferably of length substantially equal to the length of the heated plate (s).

The device preferably comprises a detection member making it possible to count the number of applications of the product and / or the time of application of the hair on the applicator member, for example the number of approximations of the arms and / or the duration of maintenance of these in close configuration. This detection member may comprise a switch, a flexible blade switch (ILS), or an optical sensor, inductive or capacitive. This detection member is preferably arranged in the housing under the pressing element so that the latter comes into contact with it in a configuration close to the arms.

The device may comprise an identifier of the application member, in particular of the refill, in particular a particular relief present on the refill or an identification chip.

The device may comprise an identification member of the application member which detects the identifier of the application member and compares it with identified identifiers. This can prevent the use of an unregistered application member or allow the device to associate with each application member a number of applications on the hair and / or a duration of application. Thus, at the change of the application member, the device recognizes the new application member.

The device may include a steam outlet for steaming the hair engaged in the device, in particular a steam outlet disposed before the applicator member, in the direction of movement of the device on the hair. The invention also relates to a hair treatment method using the device according to the invention, wherein the arms of the device are closed on a lock of hair and the latter is moved along the lock of hair to exposing the latter to the successive steps of: - applying the cosmetic product, by pressing the lock of hair on the applicator member by the pressing element, - optionally, applying steam on the lock of hair, and - smoothing the hair by heating the lock of hair in contact with at least one heated plate, in particular by passing between two heated plates facing each other.

The method may also comprise the step or steps of: identifying the application member, and / or detecting whether the application member is empty, in particular by measuring the number of applications and / or the time of application. applying the hair to the applicator member, and signaling to the user when the applicator member is empty.

In the rest of the description, identical or similar elements bear the same reference sign. For the sake of brevity of the present description, these elements are not described in detail with regard to all the embodiments. On the contrary, only the different elements of one embodiment to another are described in detail.

FIG. 1 shows the handpiece 2 of an example of a device for treating the hair of the invention.

This handpiece 2 has two jaws 3 and 4 movable relative to each other between a spaced configuration (not shown) of introduction between them of a lock of hair and a close configuration of treatment, illustrated in FIG. figure 1.

The jaws 3 and 4 are carried by respective upper 5 and lower arms 6, which are in the example considered interconnected at one end by a hinge 8, the handpiece 2 thus forming a clamp.

The upper and lower arms 6 each preferably have a total length of between 22 cm and 31 cm and define, between the hinge 8 and the jaws 3 and 4, respective half-handles 10 and 11 on which the user can press to bring jaws 3 and 4 closer together.

The upper and lower arms 6 extend along longitudinal axes X 1 and X 2 respectively, which are preferably substantially parallel to each other when the jaws 3 and 4 are closed.

An elastic return member (not shown) is preferably provided to return the jaws 3 and 4 in the spaced configuration, this elastic return member being, for example, a spring disposed about an axis of the hinge 8. The The invention is not limited to any particular way of connecting the upper and lower arms 6 to each other and the jaws 3 and 4 can be made mobile otherwise without departing from the scope of the present invention. However, the presence of a joint is widely preferred for the ergonomics it brings.

The jaws 3 and 4 define between them a hair treatment zone intended to receive a strand of hair to be treated, along which the handpiece 2 is moved during the treatment, for example in the direction from the root towards the tip of the hair.

In the example considered, the handpiece 2 is configured to comb the hair by passing through a comb 13, to apply a cosmetic product, to treat the hair with steam, and then to heat treat the hair by contact with the hair. two heating surfaces 15, 16, formed here by heated plates and for heating the hair.

The direction D of displacement of the handpiece 2 on the hair, illustrated in FIG. 2, is preferably substantially perpendicular to the longitudinal axes Xi and X2 of the arms 5 and 6.

The handpiece 2 is, in the example considered, connected by a cord 18 to a base station not shown, fixed during the treatment and connected to the sector.

This base station provides power to the handpiece 2 and its water supply for steam generation and can also perform ancillary functions for processing electrical signals received from the handpiece 2. The cord 18 which connects the handpiece 2 to the base station can thus include various electrical conductors and a water supply pipe.

A user interface, not shown in the figures, may be present on the handpiece 2 to allow the user for example to start or not certain components thereof. The application of the cosmetic product is ensured by a refill 20 carried by one of the two arms, 5 or 6, here the upper arm 5. The refill 20 comes into contact with a pressing element 21 disposed opposite the latter.

The refill 20 comprises a body 23 and an applicator member 26 held in the body 23 and having an application surface 36 coming into contact with the hair present above the pressing element 21.

The refill 20 can be attached to the arm 5 or 6 by any means, in particular, as illustrated in Figure 3, by sliding a rib 27 of the body 23 in a groove 29 of complementary shape.

The body 23 has a cavity 30 opening outwards through an opening 31 into which the applicator member 26 is inserted during the manufacture of the refill 20. The body 23 has support reliefs 32 of the the applicator member 26 extending into the cavity 30.

The body 23 and the applicator member 26 have substantially the general shape of a rectangular parallelepiped and are elongate along a longitudinal axis Z. The application member 26 is for example composed of fibers oriented substantially in the same direction, parallel to the Z axis, and assembled to form a felt. The application surface 35 of the applicator member 26 may be, as illustrated, planar.

In a variant, the applicator member 26 may be made by assembling two felts, in particular of different densities. In this variant, one of the felts may be composed of fibers oriented in one direction, in particular parallel to the Z axis, and the other of the felts may be composed of fibers oriented in a direction perpendicular to the other fibers and in particular perpendicular to the Z axis.

As can be seen in particular, in FIG. 3, the pressing element 21 has a bearing surface 36 which may be of complementary shape to the application surface 35. The bearing surface 36 can thus be flat, lying along a longitudinal axis Y substantially parallel to the longitudinal axis Z in the close position of the arms 5 and 6, and substantially of the same extent as the application surface 35. The pressing element 21 is housed removably in a housing 38 by a frontal opening of the latter. The housing 38 also opens outwards through at least one opening 37 facing the applicator member 26.

In the example illustrated in FIG. 3, the pressing element 21 is introduced into its housing 28 by sliding ribs 45 of the housing 38 in corresponding grooves 48 of the pressing element 21. The ribs 45 are arranged on lateral walls 54 and 56 of the housing 38. The grooves 48 of the pressing element 21 are arranged on the side walls of the pressing element 21 which face the walls 54 and 56, respectively. The pressing element 21 is movable along an axis Q perpendicular to the longitudinal axis Y, between a high position spaced from the bottom of the housing 38 and a low position close to it. The pressing element 21 is supported on a support means 40 extending into the housing 38, allowing a rocking movement of the pressing element 21 and now, in the open position of the arms 5 and 6, the pressing element 21 in high position.

The stroke P of the pressing element between its high position and its low position is between 1 mm and 5 mm, for example equal to about 3 mm. The displacement of the pressing element 21 is limited by the bottom 44 of the housing or by the width / groove 48.

The stroke of the pressure element advantageously allows the pressure element to be positioned in the closed position of the device, in such a way that the hair is substantially aligned, that is to say without the detachment of a lock of hair between the part located between the heated plates and the portion between the pressing member and the application member. In other words, during use of the device, the distance between the two heated plates is substantially equal to the distance between the pressing member and the application member, these two distances being measured in a substantially co-linear direction. In addition, the bearing surface 36 of the pressing element is substantially coplanar with the heating surface 16, while the application surface 35 is substantially coplanar with the heating surface 15, in normal planes. to the direction Q. This improves the smoothing of the hair by the device.

In the example illustrated in Figures 3, 5 and 6, the support means 40 is a leaf spring fixed in a recess 41 of the pressing element 21, oriented towards the bottom 42 of the housing 38. Thus, the spring to blade 40 bears on the bottom 42 of the housing 38 at a zone 43 around which the tilting element 21 is pivoted around an axis of rotation B substantially perpendicular to the axes Y and

Q

The leaf spring 40 has at its ends fastening lugs 44 coming into contact with the pressing element 21 in the recess 41 and, between them, a portion 46 convex towards the bottom 42 of the housing 38, the central portion of which defines the failover zone 43.

The height occupied by the leaf spring 40 before introduction into the housing 88 is greater than or equal to the distance / between the bottom of the housing 43 and the bottom of the recess 4L. Thus, the leaf spring 40 is always constrained by contact with the bottom of the housing 44. The distance / is for example between 1 mm and 5 mm, and for example equal to about 3 mm.

The housing 38 is substantially of the same length L as the pressing element 21. The length L of the pressing element 21 is for example between 70 mm and 110 mm, preferably 90 mm. Preferably, the pressing element has a length substantially equal to the length of the heating surface (s).

The grooves 48 have a width / greater than the thickness e of the ribs 45. The width / grooves 48 is for example between 1 mm and 5 mm, for example equal to about 3.2 mm. The thickness e of the grooves 45 is between 0.5 mm and 5 mm, here equal to 1 mm. Such a difference allows a movement of the pressing element 21 along the Y axis and / or the tilting of the latter as described above.

In the example illustrated in FIG. 3, the two ribs 45 are offset along the axis Q by a distance d, for example between 1 mm and 5 mm, for example equal to about 2 mm. The pressing element 21 is locked in the housing 38 by a protruding relief 50, visible in FIGS. 5 and 6, present in the groove 48 of the pressing element 21, and which engages in a recessed relief 52 visible in FIG. 4, the rib 45 of the housing 38.

The relief 50 does not extend over the entire width / groove 48 so that to remove the pressing element 21, simply press on the latter so that it sinks along the axis Q and that the relief 50 emerges from the relief 52. It is then possible to slide the pressing element 21 in the housing 38 towards the front.

The comb 13 is located before the applicator member 26 and the pressing member 21 in the direction D of movement of the handpiece 2. The comb 13 is integral with the pressing member 21, preferably being molded into a mold. only piece with the latter.

The comb 13 extends parallel to the bearing surface 36 and over substantially the entire length thereof.

The comb 13 has a plurality of teeth 55 each extending along an axis parallel to the axis Q. The comb 13 advantageously has more than 20 teeth 55, more preferably more than 30 teeth 55, here there are about 44 teeth.

The base of the teeth 55 is set back from the bearing surface 35, in particular with a distance r of between 0.2 mm and 5 mm, for example equal to 2 mm. This allows the hair to engage well between the bearing surface 36 and the application surface 35.

The teeth 55 are preferably all of the same height H, between 2 mm and 12 mm, for example equal to 8 mm. This height is large enough to allow a good maintenance of the hair between the teeth 55.

The teeth 55 are all at equal distances from each other. The spacing k between the teeth 55 is preferably between 0.3 mm and 3 mm, for example equal to 1 mm. The pressing element 21 may include a relief such as a tongue 57 for easier grasping.

In Figures 3 and 4, the handpiece 2 has a steam outlet 58 disposed on the arm 6 and applying after the cosmetic product on the hair.

Thus, when using the handpiece 2, the user just closes the two arms 5 and 6 on a lock of hair and moves, in the closed position, the handpiece 2 of the hair root to the ends of the latter . The hair is first subjected to combing by the comb 13, then to a product application by pressing the hair on the applicator member 26 by the pressing element 21, then to the steam by the steam outlet 58, and finally to heating between two heating surfaces 15 and 16. The example of Figures 7 and 8 differs from that of Figures 1 to 6 in that the leaf spring 40 is fixed or placed in the housing 38. The latter comprises for example a recess 60 receiving the leaf spring 40, where the latter is fixed by any suitable fastening means.

The leaf spring 40 is then in contact with the bottom of the housing 44 at its ends 44 and its zone of contact with the pressing element 21 defines a tilting zone 43.

The examples of FIGS. 9 and 10 differ from that of FIGS. 1 to 6 in that the support means 40 is a relief projecting from the pressing element 21 or the bottom 44 of the housing 28.

In the example of FIG. 9, the projecting relief 40 is a relief of the bottom 44 of the housing 28. The relief 40 has a substantially triangular shape, in section in a plane containing the longitudinal axis of the pressing element 21.

It may be otherwise, and the projecting relief 40 may in particular be semicircular or semi-polygonal.

The protruding relief 40 may be in the form of a tooth extending from the center of the bottom 44 of the housing 28, and on which the pressing element 21 bears. The pressing element 21 can bear on the end of the tooth 40, of small extent. This allows the pressure element to be tilted in at least two different axes of rotation, in particular an axis parallel to the Y axis and the B axis.

As a variant, the protruding relief 40 may have the shape of a half-cylinder extending along an axis parallel to the axis B, and the pressing element 24 bears on a generatrix of the relief 40. The example of FIG. 10 differs from that of FIG. 8 in that the projecting relief 40 belongs to the pressing element 21. The example of FIG. 11 differs from that of FIGS. 1 to 6 in that the support means 40 is a helical spring. The latter is interposed between the pressing element 21 and the bottom 44 of the housing 28. The pressing element 21 and the bottom of the housing 44 each comprise a recess 41 and 60, for holding the coil spring 40 in position. The latter is arranged so as to bear in the center of the pressing element 21. The example of FIG. 12 differs from that of FIG. 11 in that the support means 40 comprises two helical springs 40a and 40b, each arranged near one end of the pressing element 21.

FIGS. 13A to 13C illustrate variants of the bearing surface 36 of the pressing element 21.

The bearing surface 36 may be in curved cross-section, as shown in Figure 13A, in dihedral shape, as shown in Figure 13B or in truncated dihedral form, as shown in Figure 13C. The invention is however not limited to such forms. The example of FIG. 14 differs from that of FIGS. 1 to 4 in that the comb 13 is removably mounted on the pressing element 21. The comb 13 may comprise at least one groove 70, in particular a T-shaped groove, designed to engage in a complementary rib 72 of the pressing element 21. The groove 70 allows the comb 13 to be held on the pressing element 21.

The comb 13 and / or the pressing element 21 may comprise a locking member, not shown, for preventing the comb from detaching freely from the pressing element 21.

Alternatively, the comb 13 has a rib and the applicator member has a corresponding groove. Any other removable attachment means is also possible.

Another variant is illustrated in Figures 15 to 21, a pressing member 21 on which is mounted a comb 13, removably.

According to this other variant, the pressing element 21 has, over at least a part of its length, a generally U-shaped cross-section. The upper surface of the U-core here forms the bearing surface 36. The two Lateral uprights 101, 102 of the U have respective retaining beads 103 and 104. These beads are oriented towards each other and extending substantially in the longitudinal direction of the pressing element 21.

The lower arm 6, receiving the pressing element 21, has a projecting relief 105 of T cross section, the head 160 is received between the amounts 101 and 102.

The lower arm 6 also forms two respective spring receiving housings 40a, 40b open towards the pressing element 21. Additional helical spring receiving guides 40a, 40b may be provided on the pressing element 21, in particular in the opposite region. at the bearing surface 36. The pressing element 21 comprises tabs 157, one of which is visible in FIG. 18, each provided with lugs 156 facing each other. These lugs 156 are intended to slide in grooves 155 of the relief 105, substantially mid-length thereof.

The mounting of the pressing element 21 on the lower arm 6 can be achieved as follows: the two helical springs 40a, 40b are arranged in the recesses of the lower arm 6 provided for this purpose; the pressing element 21 is placed above the relief 105, so that the pressing element 21 caps the two helical springs 40a, 40b; the pressing element 21 is engaged on the relief 105, so as to cause the deformation of the lateral uprights 101, 102, until the beads 103, 104 snap onto the head 160 of the relief 105. The springs 40a, 40b urge the beads 103, 104 bearing against the head 160 of the relief 105. The beads 103, 104 prevent the pressing element 21 from detaching from the lower arm 6.

During the establishment of the pressing element 21, the tabs 157 are deformed elastically to allow the establishment of the lugs 156 in the grooves 155.

Moreover, as shown, the pressing element 21 forms a rib 106 extending in its longitudinal direction. The rib 106 is here oriented towards the outside of the device, when the pressing element 21 is mounted.

A comb 13 that can be associated with the pressing element 21 is illustrated in FIGS. 20 and 21.

The comb 13 here has two cylindrical ribs 107, 108 extending in the longitudinal direction of the comb 13, on the same side thereof.

The cylindrical ribs 107, 108, each extend over only a portion of the length of the comb 13, one after the other along the length of the comb 13.

The two cylindrical ribs 107, 108 are connected to a core 109 of the comb 13 by two blades 110, 111 extending substantially perpendicular to the teeth 55 of the comb.

The comb 13 also has a sealing tab 115 which extends, as illustrated, perpendicularly to the longitudinal direction of the comb 13 and to the plane of the tongue 57.

The tab 115 is made in the vicinity of the end of the comb 13 having the tongue 57. Preferably, the tab 115 is located, in the direction of the length of the comb 13, between the teeth 55 and the tongue 57.

The comb 13 still has, at its end opposite to that having the tongue 57, a locking relief 116. As illustrated in FIG. 21 in particular, the locking relief 116 is in the form of an elastic locking tab. deformable, comprising successively, since the end of the comb 13, opposite the end having the tongue 57: - a first bead 117, - a first recess 118 immediately adjacent to the first bead 117, so that the comb 13 has a thickness reduced at this first recess 118, - a second bead 119, of greater length than the first bead 117, and of substantially equal thickness, and - a second recess 120, such as the thickness of the comb 13 at the level of this second recess is substantially equal to that at the first recess.

Here, "thickness" means a dimension measured in a cross-sectional plane of the comb 13, and in a direction perpendicular to that of the height of the teeth 55.

Of course other examples of locking reliefs can be implemented. In particular, the second bead and / or the second recess may not be present.

Windows 152 are provided on the structure which accommodates the pressing element 21 to receive the cylindrical wall of the housings 150 when the pressing element 21 sinks.

The assembly of the comb 13 on the pressing element 21 is here carried out for example as follows: -on place the two cylindrical ribs 107, 108 opposite the corresponding housing 150 formed on the pressing element 21 in a longitudinal direction of the element pressing 21, the pressing element 21 being in the upper position with the two arms 5, 6 of the device in the separated position; - The cylindrical ribs 107, 108 are slid into the housings 150, in the longitudinal direction of the pressing element 21, the blades 110, 111 passing through the openings of the housing 150; the sliding movement is continued until the recess 118 of the locking tab is snapped onto the edge 122 of a window 121 formed at the end of the element 21.

At the end of the movement of placing the comb on the pressing element, the tab 115 closes the opening opening of the comb in the pressing element.

In use, the applicator element comes into contact with the pressing member 21 at a certain angle. Then, the pressing element 21 tilts around the axis of the lugs 156 to maximize the contact area between the bearing surface 36 of the pressing element 21 and the application surface of the applicator element. Finally, the pressing element 21 sinks vertically until the heated plates come into abutment, the lugs 156 moving in the corresponding ribs 155.

The embodiment described with reference to FIGS. 15 to 21 makes it possible to have a homogeneous contact pressure over the entire contact area between the bearing surface and the application surface. This embodiment also makes it possible to have a maximum contact area. The construction of the comb in this embodiment also has the advantage of limiting the impact thereof on the width of the device, so that the device becomes more compact.

In this embodiment, the comb and the pressing element are advantageously made by several crenel extrusions, constituted by the walls of the housings 150 and the cylindrical ribs 107, 108. This indeed makes it possible to limit, with respect to a structure made of by a single extrusion, the interactions with the springs and / or with the lugs 156 defining the central guide axis of the pressing element. The invention is not limited to the embodiments which have just been described, the characteristics of which can be combined within non-illustrated variants. The invention is also capable of numerous variants, accessible to those skilled in the art.

For example, the bearing surface 36 may have roughnesses, which may contribute to the smoothing of the hair. The pressing element and the application member may also be made of the same material.
