Description

Hand-held styling device of the straightening type with product distribution system.

The present invention relates to the technical field of handheld devices used for combing or putting hair in shape. In a preferred but not exclusive application, the invention relates to the field of electric hand-held devices used for drying and / or putting the hair in shape by means of, in particular, a flow of hot air or heat application by contact, such as hand-held electric dryers, blower brushes or even tongs for smoothing, curling or curling, without this list being limiting or exhaustive.

During the realization of a hairstyle, it may be desirable to apply, as the treatment of the tufts develops, a cosmetic product on the hair. To this end, a FR 2 136 410 patent has proposed a blower comb whose handle comprises an electric fan adapted to blow air in the direction of a hair treatment zone defined by the comb. The handle of this blowing comb also comprises a reservoir of cosmetic liquid under pressure connected by a feed circuit to a sprayer arranged in the hair treatment zone. According to this document, the handle also comprises a piston pump actuated by a push button that allows the user to activate, by pressing the finger on the button, a liquid spray through the nozzle at the level of the treatment area. Such a system effectively allows a product to be easily applied to the hair, limiting the risks of wasting said cosmetic product. However, this system does not allow to precisely dose the amount of product applied and forces the user to press the push button to obtain the distribution of products, which is not always easy depending on the part of the hair to be treated. In addition, the cosmetic deposit is neither constant nor homogeneous. Likewise, the user, in order to treat his entire hair, must press the push button numerous times, which imposes a relatively important effort that generates a certain discomfort.

In order to allow an automatic application of a cosmetic product on the hair, a patent EP 1 071 352 has proposed a dryer comprising an accessory provided with teeth for putting in the form of the hair, whose teeth comprise means of product distribution Cosmetics activated by heat or humidity. According to this document, the teeth form a cavity inside which a given amount of cosmetic products is arranged. Such a dryer effectively allows the application of a cosmetic product automatically in a small amount without the user having to worry about the amount of product applied, but suffers from the drawback that it cannot guarantee a uniform application of the cosmetic product on the hair to the extent that this application depends on the heat and / or humidity that is likely to vary greatly depending on the areas of the treated hair.

It is known from JP 2005152149 a device for applying cosmetic hair that contains a fluid reservoir and a pump at the outlet of the reservoir, which feeds a liquid distribution channel through an element that has ports of feeding of liquid, element on which it comes to clamp a comb, activating the clamping indirectly the pump.

Therefore, the need for a handheld styling device that allows an automatic distribution of a cosmetic product has arisen without this distribution having to be subject to a specific activation action by the user, while avoiding that this application is not tax of heat and humidity conditions at the level of the application point.

In order to achieve this objective, the invention relates to a styling apparatus according to claim 1.

In a particular way, the invention relates to a hand styling apparatus comprising means for putting on or combing hair that includes at least one hair treatment zone, means for distributing a cosmetic product comprising some means of application of the product located in the vicinity or in the zone of treatment of the hair, and a circuit of feeding of the means of application from a reservoir of cosmetic product, comprising at least one pump, in which the means They are, at least in part, mobile, and comprise at least one mobile roller in rotation, and in which the pump or each pump is maneuvered by the movement of the mobile roller (M) in rotation.

The use of the pump, which is adapted to be automatically maneuvered by the movement of the means for putting into shape, allows the quantity of product distributed to be subordinated to the extent of the area of the treated hair and, for example, to the length of each strand of hair treated so that this amount is perfectly dosed. In addition, to the extent that the contribution of cosmetic product results from a mechanical action on the pump, the amount of product distributed is independent of the heat and humidity conditions of the hair or also of the handheld device according to the invention. On the other hand, the apparatus according to the invention allows distributing or applying amounts of cosmetic product that are greater than those that can be applied by means of a system such as that provided for in EP 1 071 352.

Within the framework of the present invention, it is necessary to understand by cosmetic product a product comprising one or several active principles of capillary use and, in particular, a product such as that defined by the directive

European EC 93/95 of June 14, 1993. In this regard, water in liquid or gaseous form that does not contain any additive for capillary use does not constitute a cosmetic product within the meaning of the invention.

According to the invention, the pump can be made in all appropriate ways and, for example, in the form of a piston pump in which the reciprocating movement of the piston is controlled by the movement of the means for putting the hair into shape.

According to a preferred but not exclusive form of a hand styling apparatus according to the invention, each pump comprises:

-

a flexible body that defines a pumping chamber,

-

and at least one pressing body maneuvered by the movement of the means for putting on form or combing and adapted to intermittently or continuously press the flexible body.

Said embodiment allows the pump to be manufactured at a lower cost. This small manufacturing cost allows, in particular, to contemplate a regular change of the flexible body which can then be considered as a consumable, thus contributing to a good hygiene of the apparatus according to the invention.

According to a variant of the preferred embodiment, the flexible body is elastically deformable.

Thus, the tension of the pressing member is exploited to expel the product out of the pumping chamber, while the elasticity of the body is exploited to aspirate the product into the pumping chamber when the pressing member no longer exerts any tension on the flexible body. . This reversible deformation of the pump body allows the latter and its maneuvering mechanism to be carried out at a lower cost.

According to one characteristic of this variant, the distribution means comprise, between the pump and the application means, at least one non-return flap adapted to allow a circulation of cosmetic product from the pump to the application means. According to the invention, this non-return flap can be placed between the pump outlet and the application means. It can also be integrated in the application means which may comprise, for example, one or several nozzles made each of them in the form of two elastically deformable lips that are separated during the expulsion of the product and then pressed against each other. The means of application can be a silicone tube or similar material whose nozzles are a uniformly distributed sealing grooves uniformly for a distribution of the cosmetic as homogeneous as possible. A sealed anti-return valve of this type can also be integrated at the pump outlet and, in particular, in the body constituting the latter.

According to a variant of the preferred embodiment of the invention, the distribution means comprise between the cosmetic product tank and the pump at least one non-return flap adapted to allow a circulation of cosmetic product from the tank to the pump. This suction non-return flap can be located in the circuit between the pump and the tank. This non-return flap can also be integrated in the tank or be integrated in the pump inlet and, in particular, in the body constituting the latter.

According to the invention, the flexible body of each pump may be formed by a reservoir containing a sufficient quantity of product to allow the distribution of several doses of product and, in particular, contain enough product to ensure a complete treatment sequence. In this case, the flexible body can be a disposable element that can be replaced with each use of this accessory body. The flexible body of the pump can also form a monobloc assembly with the supply circuit and the distribution nozzle, this assembly also being able to be replaced every time the tank is empty.

However, said embodiment is not necessary for the invention. Thus, according to a feature of the invention, the distribution means comprise a reservoir of cosmetic product located upstream of each pump. This tank other than the pump allows to increase the autonomy of the apparatus according to the invention.

Thus, according to the invention, the deposit can be removable or, conversely, it can be fixed. The tank can be a flexible bag but not elastic and, preferably, without a vent. The bag has no elastic resistance and allows the atmospheric pressure to be transmitted to the cosmetic content. A deposit of this type is inexpensive.

When the apparatus according to the invention comprises a tank, the distribution means may comprise at least one filling hole of the tank. A hole of this type can be used to fill the tank, particularly when the latter is not removable.

According to the invention, the hand styling apparatus can be of various natures and preferably the apparatus according to the invention is an electric hand styling apparatus. Thus, the hand styling apparatus according to the invention may comprise electric means for heating the treatment area.

The hand styling apparatus according to the invention can also comprise electric air blowing means towards the treatment area.

The styling apparatus according to the invention may be designed, for example, to allow a fit or a straightening with contact heating and, in particular, to form curling tongs or a straightener. Thus, in a variant embodiment, the hand styling apparatus comprises two jaws, first and second, which are articulated between them by a hinge to be movable between an open position and a closed position, which comprise working surfaces that form the means for putting the hair in shape and defining the area of treatment of the hair in the closed position of the jaws. Each pump is then maneuvered by the movements of the jaws or work surfaces with respect to each other.

In a smoothing or curling iron configuration of this type, a longitudinal pressing member is arranged on the jaw in front of the jaw comprising the fluid distribution means. This longitudinal pressing element is arranged in front of the cosmetic distribution means and for contacting these means in the closed position of the apparatus. The organ can be a rigid parallelepipedic stem that will come to rest on the means of distribution. The organ may additionally comprise a thin layer of foam on its outer surface. This layer allows a uniform distribution of the cosmetic on the two application faces intended to press the hair during the distribution of fluid.

The pump drive can be canceled at the user's choice: for this purpose, if it is a straightening version, the pressing device arranged on the jaw in front of the jaw containing the bag can be moved and lifted through the Jaw box by the user who wishes to use his device without the option of applying cosmetic.

Within the framework of this variant, the styling apparatus may comprise electric heating means associated with at least one of the work surfaces. However, within the framework of this variant, the hand-held styling apparatus may comprise maneuvering means of each pump that are adapted to maneuver each pump after a predetermined number of consecutive opening and closing movements of the jaws. The use of said maneuvering means makes it possible to prevent the pump from being activated in each closing / opening cycle in order to allow a better dosage of the cosmetic product. Said embodiment is particularly adapted to application means comprising a felt or a porous material through which the cosmetic product is distributed.

Finally, within the framework of this variant, the work surfaces can be flat or curved, having shapes substantially complementary to each other.

According to another variant of the invention, the form or comb means comprise at least one rotating roller. A roller of this type will preferably be mobile in rotation on itself along its longitudinal axis. Thus, the means for putting on or combing hair can comprise a smooth roller, a roller with a grooved or textured outer surface or even a hair roller forming a rotating brush. Said brush may then be associated with an electric fan system to form a blower brush. The rotation of the roller of the setting means may be exploited to activate or operate the pump.

Obviously, the different features, variants and embodiments of the invention can be associated with each other according to various combinations to the extent that they are not incompatible or exclusive to each other.

In these figures, the common references designate elements common to the different forms and / or variants of embodiment.

A hand styling apparatus according to the invention is capable of being carried out in different ways depending on its purpose and the type of treatment that it is capable of applying to the hair.

Thus, the styling apparatus according to the invention can constitute a straightener, as illustrated in Figures 1 and 2, designated as a whole by the reference A. The styling apparatus A comprises a first elongated jaw 1 of generally parallelepipedic shape and which extends along a longitudinal axis L. The styling apparatus A also comprises a second jaw 2 which is also elongated and extends along a longitudinal axis L '. The jaws 1 and 2 are joined in the proximity of one of its ends by a hinge or pivot joint 4 of axis o. Thus, jaws 1 and 2 are articulated with each other and are movable between an open position O, such as that illustrated in Figure 1, and a closed position not shown.

The styling apparatus A comprises means M for shaping the hair which, according to the illustrated example, comprise for each jaw 1 and 2 a work surface, respectively S1, S2, in the vicinity of one end of the corresponding corresponding jaw to the junction 4. The work surfaces S1, S2 are located opposite each other and extend over a part only of the length of the jaws 1 and 2 in order to define in a closed position a zone Z of hair treatment . The work surfaces S1, S2 constitute, in combination with the jaws 1 and 2 that support them, movable means of putting in form M in the sense of the invention.

According to the illustrated example, the two jaws 1 and 2 also contribute to defining, by the areas of their backs P1, P2 located between the work surfaces S1 and S2 and the hinge joint 4 or pivot joint, a fastening means P of the apparatus styling A. Thus, taking into account the articulation of jaws 1 and 2 between them, the second work surface S2 is mobile with respect to the part P1 of the clamping means formed by the first jaw 1, while the first Work surface S1 is mobile with respect to the part P2 of the clamping means formed by the second jaw 2, so that the means M for forming are partly movable with respect to a part of the clamping means P.

Each work surface S1 and S2 has, according to the illustrated example, a general rectangular shape and is made of a thermally conductive material that has a surface state adapted to be placed in contact with the hair without risk of deteriorating it. Thus, each work surface S1, S2 could be smoothed, for example, by polishing or eventually coating it with an enamel, with a ceramic material, with a polymeric material or with an enamel (for example, with a small coefficient of friction) or with a glass layer

The work surfaces S1 and S2 are formed, for example, by smoothing plates respectively first 5 and second 6. The smoothing plates 5 and 6 are each associated with electric heating means 7 in contact with the surface rear of the corresponding plate, located on the side opposite the work surface S1, S2 as shown in Figure 2. The electric heating means may be made in any appropriate manner such as, for example, in the form of a resistive heating element of CTP or infrared emission. Therefore, the electric heating means 7 are located inside

the first 1 and second jaws 2. The heating means are connected by a cord 10 to an electrical supply, such as an electricity distribution network. The cord 10 feeds control means 11 that allow a user to select a setpoint temperature. Of course, the power supply of the styling apparatus A could also be ensured by batteries or batteries arranged inside one and / or other of the jaws 1 and 2. Also, the heating means could also be designed to maintain a predetermined target temperature automatically. The embodiments of the heating means and the possible control unit are well known to the person skilled in the art and, therefore, do not need a broader description in the context of the present invention.

According to an essential feature of the invention, the styling apparatus A further comprises means 20 for distributing a fluid cosmetic product, in liquid or pasty form, with a view to its application automatically on the hair during use of the apparatus A. The distribution means 20 comprise application means 21 which, as shown in Figure 2, are adjacent to the second straightening plate 6 in order to be in the hair treatment zone Z. The tank V can be located under the smoothing plate 6, which allows to reduce the volume of the handle and slightly heat the cosmetic fluid for a better application efficiency.

The application means 21 are connected to a product reservoir 22 by a supply circuit 23, as shown more particularly in Figure 3. In order to ensure the feeding of the application means 21, the distribution means 20 comprise water above the application means 21 a pump 24 located on the supply circuit 23 between the tank 22 and the application means 21.

In accordance with an essential feature of the invention, the pump 24 is maneuvered by the movement of the form-setting means M and, in the present case, by the alternating movement of the work surfaces S1, S2 and, more particularly, of the jaws 1 and 2, during closing / opening cycles of the styling apparatus A. Thus, the product feeding of the application means 21 is automatic and is subordinated to the movements of the jaws 1 and 2. According to the example illustrated in FIG. 3, the pump 24 comprises a rigid body 26 which defines with a piston 27 a pumping chamber 28 connected, on the one hand, to the reservoir 22 and, on the other hand, to the application means 21 by corresponding segments of the supply circuit 23. The piston 27 is subjected to the action of attraction of at least one and, according to the illustrated example, of two springs 29. The piston 27 carries a rod 30 which extends out of the second jaw 2 of keep that its free end 31 offers a support surface for the first jaw 1. Thus, when the first jaw 1 closes towards the second jaw 2, the first jaw comes to rest on the rod 30, so that the translation down of the piston 27 causes the volume of the pumping chamber 28 to decrease. When the first jaw 1 is opened, the pressure on the rod 30 is released and the piston 27 is pushed by the springs 29, which increases the volume of the pumping chamber 28. In order to ensure a pumping effect, the distribution means comprise on the distribution circuit upstream of the pump 24, between the tank 22 and the latter, a non-return flap 35 adapted to allow a circulation of the product of the tank 22 towards the pump 24, but not in the opposite direction. In the same way, the distribution means 20 comprise, between the external means and the pump 24 at least one and, according to the illustrated example, several non-return flaps 36 adapted to allow a circulation of products from the pump 24 towards the means of application 21 and outside, but not in reverse. The non-return flaps 36 thus prevent air aspiration. According to the illustrated example, the non-return flaps 36 are each formed by the two elastic lips of a cosmetic product application nozzle so that there are as many non-return flaps 36 as nozzles.

Thus, the product contained in the reservoir 22 is automatically taken to the application means 21 without the user having to worry about this distribution or the quantity distributed.

According to the example illustrated in Figure 3, the reservoir 22 is removably adapted in a housing 45 of the styling apparatus. Thus, the user can easily recharge the apparatus, simply by replacing the reservoir 22 that comes to be coupled on a drain cannula 46 that extends in a cantilever inside the housing 45.

According to the example described above in relation to Figures 1 and 2, the body 26 of the pump 24 is rigid. However, such a rigid body 26 is not necessary for the realization of a pump according to the invention. Thus, Figure 4 illustrates a variant embodiment of the styling apparatus according to which the body 26 of the pump 24 is made of an elastically deformable flexible material. The pump 24 used can be a so-called flat flap pump, as illustrated in Figure 10. A pump of this type is compact, strong and inexpensive. The first jaw 1 then comprises a pressing member 47 which comes to rest on the body 26 during the closing of the jaws 1 and 2. The pressure exerted by the pressing member 47 on the flexible body 26 induces the expulsion of the product it contains towards the application means 21. The pressing member 47 may be mounted on a spring 47 'whose force is chosen to ensure a controlled rate of distribution of the fluid through the application means 21 which are, for example, one or longitudinal tubes of application 21. The organ exerts a force on the pumping of the flap pump as illustrated in Figure 10. When the pressure of the pressing member 47 is released, at the opening of the jaws 1 and 2, the elastic flexible body 26 recovers then naturally its shape, which contributes to aspirating the product from the reservoir 22 to the chamber

of pumping 28 by means of the non-return flap 35. The pressing member 47 can be removed to cancel the cosmetic distribution function, at the user's choice, this possibility being illustrated in Figure 4, but contemplated in all embodiments of the straightener or tongs to curl

Several pumps can be provided alternately. A first mode is a flat flap pump illustrated in Figures 10 and 4. A second mode is a multi-wheel peristaltic pump, illustrated in Figure 8. Always for a peristaltic pump, it can be a manual peristaltic pump such as It is illustrated in Figure 11. The force F is exerted by the pressing member so that, at first, the wheel 26 'rests against the pipeline to make it sealed and, at a second moment, the curved intermediate pressing member 26 '' leans against the pipeline to advance the volume of cosmetic in the direction indicated towards the means of application 21. A pump of this type is compact and not very expensive.

The variant embodiment illustrated in Figure 4 also differs from the variant described in relation to Figures 1 to 3 in that the application means 21 are formed by a chamber 48 that opens outwards by a series of application nozzles 49 In the sense of the invention, a distribution nozzle may be formed by any hole of any shape adapted to allow the treatment product to pass outward and, more particularly, towards the hair of the user of the styling apparatus A. These nozzles can be particularly tight grooves, resulting from a manufacture called "recessed grooves" after extrusion of the tube. The chamber 48 can be a tube or several tubes parallel to each other, of silicone

or similar material, and whose nozzles 49 are watertight slits distributed in an axially uniform manner for a distribution of the cosmetic as homogeneous as possible. It should be noted that the distribution or application nozzles 49 could also be replaced or supplemented by a porous material such as an alveolar synthetic material or open alveoli or also a textile felt. This material may be an open cell foam, whose direction of the openings is directed from the nozzles to the outer surface that is intended to be in contact with the hair. The pressing member 47 can be removed by the user to cancel the cosmetic distribution function, at the user's choice, this possibility being illustrated in Figure 4, but contemplated in all embodiments of the straightener or curling tongs.

According to the example described in relation to Figure 3, the tank 22 is removable. However, according to the invention, the tank 22 could be integral to the styling apparatus A without being removable, as illustrated in Figure 4. According to this example, the tank 22 then comprises a filling hole 50 intended to receive a cannula 51 for filling a conditioning tube 52 of cosmetic product. According to this example, the filling hole 50 is associated with a non-return flap 53 preventing any product leakage after filling the tank

22

According to the embodiments described above, the pump 24 is actuated at each closure of the styling apparatus A. However, this periodicity of the action of the pump 24 is not necessary for the realization of the distribution means 20 according to the invention. Indeed, depending on the type of application means 21 used, it may be desirable to operate the pump only after a predetermined number of openings / closures of jaws 1 and 2. To this end, the invention proposes in a variant embodiment, apply maneuvering means 60 that are adapted to maneuver each pump of the styling apparatus after a predetermined number of consecutive opening / closing movements. According to the means and the example illustrated in Figure 7, the maneuvering means 60 comprise a mobile intercalating finger 61 in translation between a resting position R as illustrated in Figure 7 in full strokes and a working position T represented in mixed strokes In working position T, the interleaving finger 61 is positioned between the pressing member 47 and the flexible body 26 of the pump so that a pressure can be exerted on said body 26 when the jaws 1 and 2 are closed. On the contrary, in the rest position R, the interleaving finger 61 is disengaged from the pressing member 47 and the flexible body 26 so that, in the closed position of the jaws, no pressure is exerted on the flexible body 26 of the bomb. The interleaving finger 61 is further maneuvered by a cam 62 driven in rotation by a ratchet wheel system 63 that transforms the jaw opening / closing movements into a rotation of the cam 62 in the direction of the arrow F1. The cam 62 then comprises protrusions 64 adapted to come to regularly push the interleaving finger 61 towards the working position while it is attracted to the rest position by a spring 65. The protrusions 64 are arranged, according to the illustrated example, in the periphery of the cam 62 in order to move the interleaving finger 61 towards the working position every two closures of the styling apparatus A so that the pump 24 is actuated once every two.

According to the invention, the pump of the application means 21 is not necessarily an alternative operating pump as described above. In fact, the pump of the application means 21 can be a peristaltic pump 24 (pump 2) as illustrated in Figures 8 or 11. According to the exemplary embodiment illustrated in Figure 8, the body 26 is made in the form of an elastic flexible tube arranged in an arc of a circle and on which press members 70 regularly spaced on the periphery of a wheel 71 actuate. The operating means 60 then comprise a ratchet wheel system 72 that includes a wheel 73 associated with a non-return ratchet 74. The wheel is driven in rotation by a finger 75 integral with the first jaw 1. The finger 75 is adapted to act on the wheel 73 in order to drive it in the direction of the arrow F3 during the closing of the first jaw and to allow a free opening of the first jaw 1, while the rotation of the wheel in the opposite direction to that of the arrow F3 is prevented by the non-return ratchet 74. Therefore, the system of

ratchet wheel 72 transforms the opening / closing movements of the jaws into a rotation of the wheel 73 that is attached to the wheel 71 in order to ensure the operation of the pump 24. Alternatively, this pump can be a manual peristaltic pump as illustrated in figure 10 with an actuator that moves in two stages: to establish the seal and then to displace the fluid.

In all pump cases, Figure 5 schematically illustrates the fluid displacement operation. The fluid is contained in the reservoir 22, interchangeable or rechargeable. This reservoir is in fluid communication with the pump 24. An intermediate flexible silicone tube 24 ’arranged in series with the pump 24 (illustrated downstream, but possible upstream) reinforces and multiplies the operation and volume displaced by the pump

24. This tube is as flexible as it is capable of inflating to contain an intermediate cosmetic volume. The flexibility of this intermediate tube is obtained by its thin thickness, about 1 mm (usually 2 mm). It has been found that this allows an elastic inflation to generate more cosmetic volume (rubber balloon effect) and to ensure a much longer distribution of cosmetic over time (up to twice as long), therefore, also constant for lengths of larger strands. The intermediate tube is followed by a non-return flap 36 with the silicone tube representing the means of application 21.

According to the example described above, the work surfaces S1 and S2 are substantially flat. However, work surfaces S1 and S2 could have other forms, being complementary to each other. Work surfaces may, for example, each have a curved shape. Thus, the styling apparatus according to the invention can form tongs for curling or curling, as illustrated in the figure.

12.

According to this embodiment, the first jaw 1 defines, in its part located on the side of the electric cord 10, a clamping means P. The work surface S1, located on the side opposite to the clamping means P, has a substantially cylindrical shape of revolution and is associated with heating means not shown. The first work surface S1 is also provided with nozzles 49 for distribution or application of cosmetic product. The second jaw 2 is articulated on the first jaw 1, at a distance from the ends thereof, between the clamping means P and the first work surface S1. The second work surface S2 has the shape of a tile adapted to match the shape of the first work surface S1. According to this example, the second work surface S2 is not associated with heating means. The second jaw 2 comprises, on the side opposite the second work surface S2 with respect to the hinge joint or pivot joint 4, a branch or maneuvering member 70 which allows the styling apparatus to be opened A. The maneuvering branch 70 is then supported during the opening of the second jaw on the rod 30 of the pump 24, not visible in Figure 8, to ensure the distribution of products by the nozzles 49. The pump can be made as described in relation to the Figure 3, while the application means may be realized as described in relation to Figure 4.

A hand styling apparatus according to the invention is not necessarily a curling iron or curling tongs as described above, but can also form a rotating brush as illustrated in Figure 13. The styling apparatus A then comprises as clamping means P a handle 80 which has as means M for putting into shape a roller 81 moving in rotation with respect to the handle 80. The roller 81 comprises means 21 for applying cosmetic product that are fed by a peristaltic pump 24, as illustrated in Figure 8 whose wheel 71 is driven by the rotation of the roller 81. The roller 81 also comprises hairs to form a rotating brush. The roller is hollow with through holes for the air blown by a motor-fan assembly 82. Such a styling apparatus can then comprise a rotational drive motor of said brush 81 as well as electric air blowing means. 82. Alternatively, a flat flap pump illustrated in FIG. 10 is contemplated in front of a finger intended to rest on the flat flap pump at each complete rotation of the brush body 81. Likewise, alternatively, an illustrated manual peristaltic pump is contemplated. in figure 11 in front of a finger intended to rest on the pump at each complete rotation of the brush body 81.

FIG. 14 also illustrates another embodiment of a hand styling apparatus which constitutes, according to this example, an inverter whose M-shaped means comprise, on the one hand, a mobile roller 85 rotating on itself and, by another part, a jaw 86 adapted to pinch the hair of a strand to be treated against the roller 85. The handle 80 of the apparatus comprises hot air blowing means not visible in the figure. The handle 80 of the apparatus also comprises a part of the cosmetic product distribution means, in particular the tank and the pump not visible in the figure for feeding the application means 21 arranged in the part of the jaw 86 located in front of the roller 85 The rotation of the roller 85 is then exploited to drive the pump and ensure the feeding of the application means 21.
