The present invention relates to cleaning the skin and/or keratin fibers, such as the hair or a beard, in particular human ones, but also animal ones, in particular fur. In particular, the invention relates to an assembly for cleaning the skin and/or keratin fibers such as the hair or a beard. The invention also relates to a method for using this assembly for cleaning the skin and/or keratin fibers such as the hair or a beard.
The difficulty of being able to access running water or of having available a large volume of water is currently a reality for many people in the world and this difficulty might be accentuated in the coming decades from the viewpoint of climate change.
In this context, it is necessary to have available items of equipment which make it possible to consume less water, indeed even very little water, for common tasks for which we generally use a small amount or a great deal of water. This is a case with washing the body, for which we take baths or showers, consuming a large amount of water.
It thus appears necessary to make it possible to greatly reduce the use of water for cleaning the skin and/or keratin fibers.
Furthermore, the heating of a large amount of water is a source of CO2 emission if the energy source is not renewable; the decrease in CO2 emission is thus desirable.
US 2018/084888 relates to liquid applicators, particularly those used in hair care, and discloses a manifold dispensing cap having a base adapted to be attached to a bottle. The base seals the bottle and can move fluid from the interior of the bottle to a manifold. The manifold has a plurality of fingers which are evenly spaced radially from the centre where they extend outwardly. A central opening of the base acts as a supply port, and each finger is hollow having at its distal end an opening for the distribution of the fluid.
U.S. Pat. No. 10,285,494 discloses a fluid dispenser including a shell with a handle portion and an applicator portion opposite to the handle portion. The fluid dispenser includes a handle connected to the handle portion of the shell, and an applicator connected to the applicator portion of the shell. The applicator includes a base portion and a plurality of nodules extending from the base portion opposite to the handle portion of the shell. An interior cavity is formed between the applicator and the shell containing the fluid to be dispensed flowing from an orifice through at least one distribution orifice.
JP 3 207092 describes a brush for cleaning the skin and the scalp, comprising a reservoir, a handle, a plurality of guide portions in relief and a plurality of head portions, each being connected to a guide portion. The reservoir comprises an upper part and a lower part which can be made in one piece or in two separate pieces that can be assembled. The lower part is made of a rigid material and carries the guide portions, the latter being made in one piece with the lower part or being assembled with the latter. The guide portions are preferably made of a rigid material.
U.S. Pat. No. 1,113,843 describes a bottle secured to a hollow comb comprising teeth defining a passage terminated by an orifice. A valve secured to the comb closes the passage between the bottle and the comb.
There is a need to have available a new method of body cleaning, for the skin and/or keratin fibers, in particular human ones, capable of effectively replacing conventional aqueous body cleaning like, for example, showers, in particular hot showers, or baths, in particular hot baths.
The invention aims to meet this need and it achieves this by virtue, according to one of its aspects, of an assembly for cleaning the skin and/or keratin fibers, in particular human ones, such as the hair or a beard, comprising:
Thanks to the invention, we benefit from a new assembly for cleaning the skin and/or keratin fibers, such as human hair or beard or animal fur, that is sustainable and adapted to precisely overcome the use of a large amount of water for cleaning the skin and/or keratin fibers.
Specifically, such an assembly makes it possible to carry out cleaning by requiring little water, in particular only the water present in the cleaning composition, which makes it possible to dispense with the presence of a running water point or of a large amount of water for cleaning the skin and/or keratin fibers of a person. Such an assembly can thus be useful for carrying out the washing of a person with little or no mobility, and/or whenever there is a lack of water or when it is desired to save it. Specifically, the reservoir can accommodate a cleaning composition, and the cleaning projections allow independent and effective cleaning employing a rubbing and massaging action using the cleaning projections and without requiring the addition of water apart from the cleaning composition, in the manner of the washing performed by felines and other living creatures using their tongue and saliva.
Thanks to the presence of said at least one valve, the reservoir can be closed by closing off the supply orifice, in particular during the removal and fixing of the pad, which makes it possible to prevent the cleaning composition from flowing out of the reservoir in an uncontrolled manner, which also makes it possible to prevent any leakage of cleaning composition. When desired, in particular when using the assembly, once a pad is fixed to the body, the valve can be opened, making it possible to release the supply orifice which is no longer closed off, in order to allow the cleaning composition to pass out of the reservoir. This opening can be automatic and result from placing the cleaning composition under pressure.
The assembly may comprise at least two different pads suitable for being fixed alternatively to said body, comprising:
Said at least one valve can be configured so as to allow the cleaning composition to be retained in the reservoir in the absence of pressure exerted on said at least one elastically deformable part of the wall and the cleaning composition to exit from the reservoir when pressure is exerted on said at least one elastically deformable part of the wall. The valve can thus be closed at rest and opened under the effect of the pressure exerted by the user when the latter presses on the body in order to reduce its interior volume.
Said at least one valve may be integral with the body in the absence of a pad. In other words, when the pad is separated from the body, the valve remains attached to the body.
Said at least one valve may have an axis oriented substantially perpendicularly to a longitudinal axis of the body. By axis of the valve, one should understand the direction along which the composition flows when the valve is open, the opening of the valve being caused by the pressure of the composition upwards the valve.
Said at least one valve has, for example, a base of annular shape and a shutter fixed to the base and comprising at least two elastically deformable membranes cooperating in the absence of pressure so as to prevent any exit of the cleaning composition from the reservoir and defining, between them, an opening when pressure is exerted on the elastically deformable part of the wall of the body in order to allow the cleaning composition to exit from the reservoir.
The assembly preferably comprises at least one retaining element arranged to cause the valve to cooperate with the supply orifice, the retaining element forming a ring of external diameter substantially equal to that of said supply orifice and of internal diameter substantially equal to the external diameter of a part of the valve, so as to externally maintain the valve and to internally cooperate with the supply orifice.
The body can be made of at least one elastically deformable material, in particular of one elastically deformable material, for example chosen from the group consisting of a thermoplastic elastomer (TPE), a high-performance elastomer (HPE), in particular a high-performance polyurethane elastomer or a high-performance thermoplastic elastomer, a polyurethane, a silicone and a polyamide, a biocellulose and a fungus mycelium. The material chosen is preferably chosen from biopolymers or bioplastics, that is to say comprising biodegradable polymers, polymers resulting from renewable sources, for example biobased (obtained by a process starting from plant matter), or polymers belonging to both these categories. The material chosen is preferably a recyclable or reusable polymer. The material can be chosen, for example, from the range of biopolymers sold under the name Terraprene®, thermoplastic elastomer (TPE) compounds, by FKUR Polymers, or else from the range of thermoplastic elastomers (TPEs) containing starting materials resulting from renewable plant products sold under the name Dryflex® Green by Hexpol, or else from the range of biobased thermoplastic elastomers (BioTPEs) sold by NaturePlast.
The or each pad can be made of at least one elastically deformable material, in particular of one elastically deformable material, for example chosen from the group consisting of a thermoplastic elastomer (TPE), a high-performance elastomer (HPE), in particular a high-performance polyurethane elastomer or a high-performance thermoplastic elastomer, a polyurethane, a silicone and a polyamide, a biocellulose and a fungus mycelium. The material chosen is preferably chosen from biopolymers or bioplastics, that is to say comprising biodegradable polymers, polymers resulting from renewable sources, for example biobased (obtained by a process starting from plant matter), or polymers belonging to both these categories. The material chosen is preferably a recyclable or reusable polymer. The material can be chosen, for example, from the range of biopolymers sold under the name Terraprene®, thermoplastic elastomer (TPE) compounds, by FKUR Polymers, or also from the range of thermoplastic elastomers (TPEs) containing starting materials resulting from renewable plant products sold under the name Dryflex® Green by Hexpol, or also from the range of biobased thermoplastic elastomers (BioTPEs) sold by NaturePlast.
The materials constituting the body and the pad can be identical or different, in particular as regards their elasticity.
The pad provided for the cleaning of the skin or at least the cleaning projections of this pad can be more flexible than the pad provided for the cleaning of the keratin fibers or at least than the cleaning projections of this pad.
The or each pad advantageously comprises, on an inner surface opposite to the outer surface, a fixing projection, the body having on an outer face a complementary fixing projection able to cooperate, in particular mechanically, with the fixing projection of the pad in order to fix the pad to the body.
In this case, the complementary fixing projection of the body can delimit, at least partially, a zone comprising said supply orifice(s).
Still in this case, the complementary fixing projection of the body comprises, for example, a flange extending toward the outside of the body with an at least partially closed contour, the contour of the flange having a shape similar to that of the outer contour of the fixing projection of the pad, which fixing projection can form a rim configured to hug the shape of the flange.
By virtue of the presence of fixing projections on the pad and on the body, which are capable of cooperating with one another, it is easy to secure and then detach the pad and the body, in particular when the pad and/or the body is/are made of at least one material elastically deformable at least at the fixing projection.
In order to facilitate the removal of the pad, the latter can comprise at least one tongue, in particular two tongues, making it possible to grasp the pad in order to remove it from the assembly, when desired. This or these tongues can be present at at least one longitudinal end of the pad, in particular extending from an inner surface of the pad.
The pad having a longitudinal axis, the body having a longitudinal axis, the longitudinal axis of the pad and the longitudinal axis of the body may make an angle less than 45°, preferably being substantially parallel.
The body preferably comprises a plurality of supply orifices, in particular five supply orifices, in order to make possible the discharge of the cleaning composition, said supply orifices being, for example, arranged in a row, in particular provided in order to extend substantially at the middle of the pad when the latter is fixed to the body. The supply orifices preferably are more than two, more preferably more than three, even more preferably more than four, and preferably less than ten, more preferably less than eight. The supply orifice(s) are traversing. Having a plurality of supply orifices may allow to reduce the size of each orifice and provide the user better control over the flow of the dispensed composition as well as a better surface distribution of the composition.
In the case where the supply orifices are arranged in a row and in the case where the pad extends along a curved longitudinal axis, said row can be substantially curved with a curvature similar to a curvature of said curved longitudinal axis of the pad.
The cleaning projections are designed to allow massage, rubbing or brushing of the skin and/or keratin fibers with the pad.
The cleaning projections may include barbs.
In one particular embodiment, the cleaning projections are formed by barbs.
At least some of the barbs are for example configured to imitate papillae of the tongue of a feline, in particular of a cat.
The term “barbs configured to imitate papillae of the tongue of a feline” is understood to mean barbs which each imitate the shape of a papilla of the tongue of a feline, for example being curved in a similar way to that of a papilla. Of course, some parameters of this shape can be adapted in order to be better suited in particular to human head hair or animal fur. In particular, the barbs of the pad can be harder and/or longer than the papillae. This can make it possible to ensure efficient brushing of human head hair, for example, by going as far as the scalp, which can thus also be massaged.
The dispensing opening can be formed on the outer surface of the pad or in one of the cleaning projections.
The assembly may comprise for each supply orifice a respective dispensing opening.
In the case where the cleaning projections comprise barbs, at least one barb can have a passage opening onto the dispensing opening.
In this case, the passage of said at least one barb which opens onto the dispensing opening can pass through the barb from an end connected to the outer surface of the pad up to a free end, the free end comprising the dispensing opening for the dispensing of the cleaning composition.
All or some of the barbs can have a shape with a diameter which decreases from the end connected to the outer surface of the pad up to the free end.
Said at least one pad comprises, for example, barbs of at least one first shape and barbs of at least one second shape, differing in particular from the first shape in the diameter, the shape of the free end, the length and/or the straight or curved longitudinal axis along which the barbs extend between their end connected to the pad and their free end.
At least some of the barbs, or even all of the barbs, of the pad, in particular the pad provided for the cleaning of the keratin fibers, can have a curved shape, the longitudinal axis of said barb(s) then being curved.
At least some of the barbs, in particular all of the barbs, of the pad, in particular the pad provided for the cleaning of the skin, can have a rectilinear shape, in particular of substantially conical shape.
A region of the outer surface of the pad, in particular of the pad provided for cleaning the skin, is, in one particular embodiment, devoid of barbs, said region being for example provided with at least one lamella, in particular with a plurality of lamellae, extending substantially orthogonally from said outer surface. In this case, the cleaning projections comprise barbs in one region of the outer surface of the pad, and lamellae in another region of the outer surface of the pad.
Such lamellae can have a scraping effect on the skin, for example to remove remaining cleaning composition and/or dead skin cells or other impurities. The lamellae can be arranged parallel to one another and/or parallel to the outer edge or contour of the outer surface of the pad in said region. It is understood that the parallelism can concern curved lines, which are thus equidistant over their entire length. The barbs can extend along rows, for example in the extension of the lamellae, when present, distributed over another region of the pad.
The pad can extend along a curved longitudinal axis, it being possible for said body to then have, at least in a part intended to cooperate with the pad, a similar curved shape.
Such a shape can be ergonomic for handling and using the assembly.
The body can extend from a lower end up to an upper end, along a longitudinal axis, which is preferably curved, the body comprising a base portion comprising in particular a gripping part, including the lower end, and an upper portion comprising the upper end, a width of the base portion being greater than a width in the upper portion, the width of the upper portion preferably continually decreasing in the direction of the upper end.
The upper portion may include the part of the body which is intended to cooperate with the pad and may include, where appropriate, at least part of said complementary fixing projection.
The body can comprise, in a rear part, the gripping part and, in a front part opposite to the rear part, said complementary fixing projection.
The body preferably has an ergonomic shape, for example suited to the user, in particular in the gripping part.
Furthermore, the body advantageously comprises an opening for filling the cleaning composition, the assembly comprising an at least partially removable stopper arranged to close said filling opening.
In this case and in the case where the body comprises a base portion having a lower end, the filling opening is preferably located at a lower end of the body, in particular at a lower end of the base portion of the body.
The filling opening can be defined by a skirt extending inside or outside the reservoir.
An adapting piece can be inserted between the stopper and the body so as to make it possible to cause the stopper and the body to cooperate with one another. For example, the adapting piece can be fitted by force or by snap fastening to the skirt extending outside the reservoir and defining the filling opening. The adapting piece can comprise a skirt extending substantially parallel to the skirt of the body and having an external thread capable of cooperating with a corresponding thread present on an inner skirt of the stopper in order to be able to close the filling opening.
The lower end of the assembly can be flat and wide enough to be able to rest on a flat support and allow the assembly to be maintained without requiring the intervention of a person.
The body can comprise an air intake orifice. Such an orifice can be provided with a valve, in particular with a valve similar to that which equips the supply orifice(s) for the discharge of cleaning composition.
The assembly can comprise a cleaning composition contained in the reservoir. Such a cleaning composition can be suitable for cleaning the body and/or keratin fibers. The cleaning composition is preferably low-foaming or even nonfoaming, so as to prevent the development of foam within the assembly which may interfere with the operation thereof.
The shape and dimensions of the assembly are preferably adapted for good handling by the user. The total height of the body of the assembly can in particular be between 5 cm and 20 cm, in particular between 7 cm and 13 cm. The capacity of the reservoir can be between 3 cl and 20 cl approximately, in particular between 4 cl and 15 cl. The width of the assembly can be between 3 cm and 8 cm, in particular about 5 cm. The depth, from the front to the rear, of the assembly can be between 3 cm and 10 cm, for example, in particular between 7 and 9 cm, it being possible, of course, for this depth to depend on the pad which is fixed to the body.
Another subject of the invention, according to another of its aspects, in combination with the foregoing, is a pad intended to be in contact with the skin and/or the keratin fibers, capable of being removably fixed to the body of the assembly, and having an outer surface on which are provided cleaning projections and at least one dispensing opening, said at least one dispensing opening being positioned on the pad so that, when the pad is fixed to the body, the cleaning composition can pass from the reservoir to said at least one dispensing opening.
Another subject of the invention, according to another of its aspects, is a method for using the assembly as defined above, for cleaning the skin and/or keratin fibers, comprising the following steps:
When one or more lamellae are present on the pad, it is also possible to carry out scraping of the skin.
When the body comprises an air intake orifice provided with a valve, said valve can be arranged in order to open when the user stops pressing on the body so as to make possible the entry of air. The body can then return to its initial shape.
Another subject of the invention, according to another of its aspects, in combination with the foregoing, is a method for manufacturing the body of an assembly as defined above for cleaning the skin and/or keratin fibers, the manufacturing method comprising the following steps:
A better understanding of the invention can be obtained on reading the detailed description which will follow of nonlimiting exemplary embodiments thereof and on examining the appended drawing, in which:
In the remainder of the description, identical elements or identical functions carry the same reference sign. For the purposes of conciseness of the present description, they are not described in relation to each of the figures, only the differences between the embodiments being described.
In the figures, the actual proportions have not always been respected, for the sake of clarity.
A description will be given of a first embodiment in the light of
The assembly 1 also comprises at least one valve 6, in this example five valves 6 each capable of closing or not closing one of the supply orifices 5.
The assembly 1 also comprises at least one pad 10, in this example two pads 10, respectively 10a and 10b, intended to be in contact, for the purposes of cleaning, with the skin and/or the keratin fibers. In the example illustrated, the pad 10a is intended to be in contact with the skin, while the pad 10b is intended to be in contact with the keratin fibers.
Each pad 10 is capable of being removably fixed to the body 2 and has an outer surface 15 comprising cleaning projections 7 comprising, in this example, barbs 16.
In the example illustrated, at least one barb 16, referenced 16a, as visible more precisely in
As can be seen in
Still in
Each valve 6 is configured so as to allow the retention of the cleaning composition in the absence of pressure exerted on the wall 3 in its elastically deformable part and the exit of cleaning composition when pressure is exerted on the elastically deformable part of the wall 3. As visible in
The assembly 1 also comprises a stopper 12, visible in
The body 2 is made entirely of an elastically deformable material in the example illustrated, in particular of a high-performance biobased elastomer, that is to say obtained by a process proceeding from plant material, in this example consisting of a thermoplastic elastomer (TPE) from the range of bioTPEs sold by NaturePlast, being produced in one piece by material injection molding. Likewise, the pads 10 are entirely made of at least one elastically deformable material, also of high-performance biobased elastomer in this example consisting of a thermoplastic elastomer from the range marketed under the name Dryflex® Green sold by Hexpol, each also produced in one piece by material injection molding.
For the removable fixing of the pad 10a or of the pad 10b to the body 2, as visible in
For its part, as visible in particular in
In the example illustrated, the complementary fixing projection 28 forms a flange extending toward the outside of the body 2 and having a contour 35, substantially in the shape of a bean, which is closed around a zone 36. The contour 35 of the flange has a shape similar to that of the outer contour 29 of the pads 10.
In the example illustrated, tongues 31 are formed at the longitudinal ends of the pad 10 to facilitate the gripping of the pad 10, in particular for its removal from the body 2.

As can be seen in
As visible in
The pad 10a is not entirely covered with barbs 16, in this example. It comprises a region 45, located in an upper part of the pad 10a as visible in
As can be seen in particular in
Furthermore, the body 2 has, in addition to the front part 27 comprising the complementary fixing projection 28, a rear part 47, opposite to the front part 27, defining an ergonomic gripping part. The reservoir 4 is thus delimited by the wall 3 which also partly forms the gripping part of the assembly.
There is no separate handle in this example.
It is not a departure from the scope of the invention if a separate handle is provided in the body, in addition to the reservoir, in particular if the shape of the reservoir is not ergonomic. In this case, the body may include a handle forming a bow on the upper face of the reservoir, in which handle it would be possible to engage the hand and thus press on the reservoir to release the cleaning composition instead of squeezing the reservoir in the absence of a separate handle.
The body 2 has an opening 50 for filling the cleaning composition, as can be seen in
To use the assembly 1 according to the invention, the reservoir 4 is filled with a cleaning composition.
A pad 10 is secured to the body 2, for example the pad 10a for cleaning the skin, by means of the complementary projections 26 and 28.
The elastically deformable rear part 47 of the body 2 is pressed so as to create an overpressure aimed at opening the shutters 20 of the valves 6 and to allow the cleaning composition to pass from the reservoir 4 to the dispensing openings 18 at the end of the barbs 16a. The skin is rubbed and massaged, for example in a circular manner, in order to clean it. The lamellae 46 then make it possible to scrape the skin in order, for example, to remove all or some of the resulting cleaning composition and impurities and dead cells.
For cleaning the keratin fibers, the procedure is the same except that the pad 10b is secured in place of the pad 10a and the barbs 16 are brought into contact with the keratin fibers so as to apply a cleaning composition to the latter and to brush or comb them or to massage the scalp.
The invention makes it possible to effectively clean the skin or the keratin fibers using the assembly 1 provided according to the invention without requiring the addition of water or requiring little addition of water, which may prove to be useful in the case of a lack of water or for a person with little or no mobility.
As a variant, the reservoir may be filled with a flexible bottle surmounted by a cone which would be inserted into a hole made in the upper face of the reservoir, possibly formed in an elastomeric skirt which opens when the bottle of cleaning composition is inserted therein and which closes when it is removed.
There is shown in
Furthermore, in this embodiment, the retaining elements 11 are made in one piece with the pad. The cleaning composition S can be seen in
Furthermore, in the embodiment of
An adapter piece 55 is interposed between the stopper 12 and the body 2 so as to allow the stopper 12 and the body 2 to cooperate with each other. The adapter piece 55 is mounted by force or by snap-fastening on the skirt 53 extending outside the reservoir 4. The adapter piece 55 itself comprises a skirt 56 extending substantially parallel to the skirt 53 of the body 2 and having an external thread capable of cooperating with a corresponding thread present on the central stud 52 of the stopper 12 in order to be able to close the filling opening 50. As can be seen in
Three other possible body shapes 2 have been shown in
In
Finally,
In
The first step 60 consists in taking an image, in this example to be scanned, of a hand M of a user using a device O. In a second step 61, the images from the first step 60 are processed, so as to define an appropriate profile of the wall 3 of the body 2. In a third step 62, the body 2 is produced by additive manufacturing of polymer material. In a fourth step 63, the desired body 2, adapted to the user, is thus obtained.
It should be noted that, in this method as well as for the examples of
Needless to say, the invention is not limited to the examples that have just been described.
In particular, the shape of the body 2 can be modified without departing from the scope of the invention.
The fixing 26 and complementary 28 projections may be different from those which have been described above while making it possible to cooperate with one another for the removable fixing of the pad 10 to the body 2, without departing from the scope of the invention.
The cleaning projections 7 may not comprise barbs 16. The dispensing opening 18 may not be formed in a barb 16 but be present at the outer surface 15 of the pad 10 or be formed in a cleaning projection 7 other than a barb. In this case, the dispensing opening 18 is nevertheless intended to be positioned on the pad 10 so as to allow the cleaning composition to exit from the reservoir 4 to the dispensing opening 18 by passing through the supply orifice 5.
The diameter of a barb 16 may be between 0.5 mm and 3 mm, preferably being around 1 mm approximately.
In a variant, the presence of the pad is necessary to unlock the valves and allow them to open under the pressure of the cleaning composition.
In another variant, the pad constrains the opening of the valves, so that, depending on the pad placed on the body, the valves can open more or less.
