Description

The present invention relates to devices for performing a cosmetic or dermatological treatment, including devices for packaging a cosmetic or dermatological product. WO 2008/079451 discloses a packaging device comprising a container and a dispensing head comprising an applicator member rotated relative to the container by an electric motor. The start is made by moving a ring located at the base of the dispensing head. The publications FR 2 885 779, US 2003/0171702 or US Pat. No. 6,652,888 describe conditioning and application devices comprising a vibrating source. An external switch allows the user to trigger the operation of the vibrating source when using the device. Application FR 2 919 477 describes devices comprising containers provided with closure assemblies equipped with vibrating sources. Switching on is done by means of a switch actuated by the user.

There is a need to further improve treatment devices equipped with an electrical system. According to one of its aspects, the subject of the invention is a device for cosmetic or dermatological treatment, comprising: an electrical system, a source of electrical energy, - a switching system for selectively supplying the electrical system with the source of electrical energy, the switching system having a surface movable relative to a gripping surface of the device during the treatment, movable surface on which the user can act to change the state of the switching system by moving a cover of protection or closure of the device, in particular not being used to contain a possible product to be applied, relative to the gripping surface, or by applying said moving surface against the keratin materials to be treated. By treatment device must be understood any device capable of allowing the user to perform a cosmetic or dermatological treatment. It may be a device for packaging a cosmetic or dermatological product.

The moving surface can be actuated by placing and removing a protective cover. The device may comprise a support of the electrical system and / or the source of electrical energy.

In a variant, the moving surface is intended to be applied to keratin materials to be treated. The device is thus easy to use and frees the user from a specific action on the switching system during operation of the electrical system. The switching system may also not be external, which improves the aesthetics and may facilitate the cleaning of the device with running water, if any. The device is advantageously portable with one hand and autonomous, being entirely manipulated by the user to distribute and / or apply the product. The device may include: - a fixed contact with respect to the gripping surface, a movable contact with respect to the gripping surface, - a resilient return member biasing the movable contact resting on the fixed contact, - a first integral part the support, a second part movable relative to the first part, for example constituted by the aforementioned protective cover, the first and second parts can cooperate to take a first configuration where the second part causes the movable contact to move away, against the action of the elastic return member, the fixed contact, a displacement of the second part from this first configuration causing the movable contact to bear against the fixed contact. This displacement corresponds for example to the removal of the protective cover. The electrical system can for example be automatically switched on when handling the second part. The return member may be defined by an electrical contact, in particular an electrical contact carried by the support. The latter can be mobile relative to the gripping surface. The electrical contact comprises for example an elastically deformable blade which can be fixed at two ends opposite to the support.

The second piece can be completely separable from the first. This is for example a closure cap of a dispensing orifice or protection of a surface intended to come into contact with keratin materials, this surface may or may not be used to dispense a product. This surface can be defined by a metal dome, for example aluminum or steel or a non-metallic material. The support can be snapped onto the first part, in particular with a possibility of displacement in translation relative to the first part. This displacement can take place during the displacement of the second piece. The electrical power source may include a button cell and the latter and the electrical system may be stacked. The stack may be stationary relative to the gripping surface or movable relative thereto, especially in the case where the movable surface which controls the operation of the electrical system is pressed against the keratin materials to trigger the operation of the electrical system. The displacement can be performed on a stroke of 1 to 5 mm, for example.

The electrical system advantageously comprises a metal case in contact with an electrode of the button cell. The aforementioned fixed contact can be defined by the housing. This reduces the number of components of the device and simplify manufacturing. The first part may comprise a chimney and the support may comprise a portion, for example of annular shape, engaged on this chimney and carrying the movable contact. The first piece may be secured to a closure sub-capsule of a container containing a cosmetic or dermatological product, for example a care product or makeup. The electrical system may include a disk motor for generating vibrations. The first piece can support a massage member, including a massage dome. In this case, the electrical system is for example useful to vibrate the massage dome. The second piece can be screwed, snapped or mounted by a bayonet attachment on the first piece. The second piece allows, when so fixed on the first, to maintain the fixed contact away from the movable contact.

The source of electrical energy, the electrical system, the support and the first part may belong to a closure assembly of a container containing a product to be applied. The invention further relates, in another of its aspects, independently or in combination with the foregoing, to a cosmetic or dermatological treatment device, comprising: a source of electrical energy, an electrical system, intended to be powered by the source of electrical energy, a support, a fixed contact with respect to a gripping surface of the device, a movable contact with respect to the gripping surface, a resilient return member biasing the movable contact resting on the fixed contact a first part secured to the support, a second part movable relative to the first part, the first and second parts being able to cooperate to take a first configuration where the second part causes the moving contact to move away, against the action of the elastic return member, of the fixed contact, a displacement of the second part from this first configuration causing the moving contact to move press on the fixed contact. The invention further relates, in another of its aspects, independently or in combination with the foregoing, a cosmetic or dermatological treatment device comprising: a first part that can be manipulated by the user to perform the treatment and / or to distribute a product used for processing and comprising: - a source of electrical energy, - an electrical system, - a switching system on which the operation of the electrical system depends, - an element which can be fixed on the first part and which is not used to contain the possible product to be applied, the switching system being configured to automatically change state during the removal of this element.

The invention further relates, in another of its aspects, independently or in combination with the foregoing, to an electrical device comprising: - a disk motor comprising a metal casing, - at least one button cell stacked with the disk motor, so that the metal housing of the latter is electrically in contact with an electrode of the button cell, - a switching system having an electrical contact in contact at least during operation of the electrical system with one of the housing and the battery and another electrical contact in contact, at least during operation, with the other of the housing and the battery. For example, one of the contacts is movable relative to the stack of the engine and the button cell and can be applied against the metal case or the button cell, so as to be powered. One of the contacts can still be fixed relative to a gripping surface and the stack constituted by the battery and the housing can move relative to a gripping surface to bear against this contact. The relative displacement of the contact and the stack can be carried out in various ways and for example under the effect of an action on a closing cap or protection of the device or on a control member of a shutter system, this shutter system selectively communicating a dispensing orifice with an interior space of a container containing a reserve of a fluid to be dispensed through the dispensing orifice. The subject of the invention is, according to another of its aspects, independently or in combination with the foregoing, a device for packaging and dispensing a cosmetic or dermatological product, comprising: a container containing a reserve of said product, for example in a fluid form or solid block, - a closure assembly of the container, which can be fixed on the container and preventing when it is in place on the container access to the product, this closure assembly comprising two parts that can relative to each other, for example separated from each other, the closure assembly further comprising a source of electrical power, an electrical system and a switching system, the latter changing from one to the other. state in response to a displacement of the two parts relative to each other, for example a separation of the two parts. For example, one of the parts is a closing cap or protection and its removal causes the switching system to change state, for example to power the electrical system, which may include for example a motor to generate vibrations.

The displacement of the second piece relative to the first can release access to a surface used for treatment, for example by being brought into contact with the keratin materials to be treated. This surface is for example a message dome. The invention will be better understood on reading the following detailed description, non-limiting examples of implementation thereof, and on examining the appended drawing, in which: FIG. schematically and in elevation, an example of a device made according to the invention, - Figure 2 shows the device of Figure 1, protective cover removed, - Figure 3 is a longitudinal section of the device of Figures 1 and 2 in a configuration where the electrical system is powered, - Figure 4 is a longitudinal section along IV-IV of Figure 3, - Figure 5 is a view similar to Figure 4, in a configuration where the electrical system is no FIG. 6 is a longitudinal section along VI-VI of FIG. 5; FIGS. 7 to 9 are cross-sections, respectively along VII-VII, VIII-VIII and IX-IX, of FIG. 5; FIG. 10 represents in isolation a variant of FIG. the resilient return member 11a and 11b represent separately, in perspective according to two different angles of view, the support; FIG. 12 is an exploded view of another variant embodiment; FIGS. 13A to 13E illustrate an example of use of a device produced in accordance with the invention; FIG. 14 shows in elevation another embodiment of a device according to certain aspects of the invention; FIG. is an exploded view of the device of FIG. 14, and - FIG. 16 schematically and partially shows, in axial section, the closure assembly of the device of FIGS. 14 and 15. The device 1 according to the invention, represented on FIG. FIGS. 1 to 9, comprise a container 2 containing a product to be applied, this container possibly being any, for example having, as illustrated, a dispensing cannula 3, provided with a thread 4 enabling the attachment of a set closing the container 2. The latter is for example a flexible tube on which the user can press to distribute the product. The closure assembly 5 may comprise a sub-capsule 8, designed to seal the container 2, by screwing itself onto the thread 4, this sub-capsule 8 being received in a part 10 whose outer surface 11 constitutes a gripping surface for the user and allows the latter to separate the closure assembly 5 of the container 2. The sub-capsule 8 may be fixed in various ways in the part 10, for example by snapping, which may comprise as illustrated a annular groove 12 in which is snapped an annular bead 13 of the sub-capsule 8, this bead 13 being for example made at the base of a mounting skirt 15 frictionally applied to the inner surface 17 of a tubular skirt 18 of the piece 10. The mounting skirt 15 may be serrated, as well as the inner surface 17, as can be seen in Figure 7, to reduce the risk of relative rotation of the sub-capsule 8 by rapper ort to the piece 10, during the screwing or unscrewing of the closure assembly 5. Where appropriate, the piece 10 can be made directly with a closure means of the container 2, for example molded in one piece with the 10. The part 10 can carry, as illustrated, a massage dome 25 and an electrical system 27, and a power source 28 for powering the electrical system 27. In the example, the electrical system 27 comprises a disk motor driving in rotation an eccentric flyweight contained within its housing so as to produce vibrations. The axis of rotation of the flyweight is for example parallel to an axis of symmetry of the dome 25.

The closure assembly 5 also comprises a support 30, which may be made by plastic molding, movable relative to the part 10 along the X axis, between a first position shown in FIG. 5 and a second position represented in FIG. FIG. 4. The axis X may coincide, as illustrated, with the longitudinal axis of the device. The electrical system 27 rests permanently, in the example illustrated, against the upper end 40 of a chimney 41 of the part 10, which is for example made in one piece by molding thermoplastic material with the part 10, this chimney 41 being for example centered on the axis X and being connected below a transverse wall 42, which itself is supported by the tubular skirt 18. The electrical system 27 comprises in the example in question a metal casing which comes into contact with an electrode 50 of the energy source 28, which consists of at least one pillar e button, for example type LR 44 or SR44. Thus, the lower face 51 of the metal housing of the electrical system is permanently connected to the electrode 50 and constitutes a fixed contact. An electrical contact 54 permanently rests on the other electrode 53 of the energy source 28. This electrical contact 54 is carried by the support 30, being for example fixed to the upper end of diametrically opposite uprights 58 of the support 30, visible in particular in Figures 11A and 11B. The contact 54 may be formed, as illustrated, by an elastically deformable metal blade, having a central curved portion 60, concave towards the energy source 28.

Under the effect of the elastic restoring force exerted by the contact 54 on the energy source 28, the support 30 tends by reaction to move upwards, away from the container 2, relative to the part 10. The support 30 comprises a central portion 66, for example of annular shape, which carries a movable contact 68, for example also of annular shape. The latter may come into abutment against the contact formed by the underside of the metal housing of the electrical system 27, in the configuration illustrated in FIG. 3. The electrical system 27 comprises a first supply wire 70 connected to the movable contact 68 and a second feed wire 71 connected to the fixed contact 54. The support 30 may comprise, as illustrated, tabs 75, for example two in number and diametrically opposed, having teeth 79 which are snapped into openings 77 of the part 10 , with a possibility of displacement relative thereto along the axis X, so that the support 30 can move axially along the axis X relative to the part 10, between a position where the teeth 79 abut against the upper edge 83 of the openings 77, as shown in Figure 4, and a position where the teeth 79 are spaced from the upper edge 83 of the openings 77, as shown in Figure 5.

When the support 30 moves from the position corresponding to Figure 4 to the position corresponding to Figure 5, the contact 54 is deformed elastically. The support 30 can be held in the position of Figure 5 by a protective cover 90, which can be fixed removably on the part 10, for example by a bayonet type fixing, by screwing or otherwise.

The lower end edge 96 of the cap 90 presses on the teeth 79 when the cover 90 is in place on the part 10, to keep them away from the upper edge 83 of the openings 77. Thus, when the cap 90 is in place, the central portion 66 of the support 30 is remote from the electrical system 27, and the movable contact 68 is not powered for lack of contact between the metal housing of the electrical system 27 and the movable contact 68. When the user removes the cover 90 , the contact 54 recalls, by elastic deformation, the support 30 upwards, until the movable contact 68 comes into abutment against the fixed contact formed by the housing of the electrical system 27, as illustrated in FIG. 4.

The dome 25 is fixed on the piece 10 without being able to move relative to it, so that a pressure exerted on the dome 25 does not move the support 30. To use a device made according to the invention, the The user can, as illustrated in FIGS. 13A to 13E, begin by applying the product, for example a concealer or anti-wrinkle product, contained in the receptacle 2, after having unscrewed the closure assembly 5, but with the cap 90 still in place on the part 10. Then, the user can remove the cover 90, which causes the automatic start of the electric motor and the generation of vibrations. At the moment when the user removes the cover 90, the piece 10 may have been brought back to the container 2 or not. The user can use the assembly formed by the part 10 and the container 2 as a gripping means for moving the dome 25 on the surface to be treated.

The user can massage the area on which the product has just been applied with the dome 25. Alternatively, the user first performs a massage, then a product application, and possibly a massage again.

The embodiment variant illustrated in FIGS. 14 to 16 comprises a communication system making it possible to put the electrical system 27 into operation when a pressure is exerted on a surface 200 intended to contact the keratin materials during the treatment. This surface 200 is for example defined by a massage dome 25, which is for example made of a metal, for example aluminum. In the embodiment of Figures 14 to 16, the device 1 comprises an assembly 5 which serves to close the container 2, which is for example a tube, as illustrated. The assembly 5 comprises a part 210 (also called fret), defining a gripping surface 211 manipulated by the user to open the container 2, inside which is fixed a sub-capsule 215 which serves for example to the sealing the container 2 and comprises for this purpose a mounting skirt 216. The skirt 216 may receive a threaded insert, not shown or be provided with a thread. Fixing can still be done by snapping, if necessary, or by friction.

The assembly 5 comprises a power source 28, constituted for example by a button cell, and an electrical system 27, for example a disk motor, which can be, as illustrated, stacked with the energy source 28. The system Electrical 27 may comprise as in the embodiment of Figures 1 to 9 a metal housing.

The assembly of the electrical system 27 and the power source 28 is carried by an element 230 which is used for mounting on a support portion 235, which is, in the embodiment illustrated, made in one piece by molding material with a base portion of the sub-capsule 215, being connected thereto by branches 240 forming a spring, for example each shaped helical portion. Thus, the support portion 235 can move towards the bottom of the container 2 against the elastic return action of the branches 240. The support portion 235 carries the dome 25.

The electrical system 27 can be held against the energy source 28 by a holding element 245 which is, for example, fixed inside the element 230 and can be provided, as illustrated, with a central stud 250 of which the The upper end comes into contact with or is located near the inner surface of the dome 25 near its top.

The upward movement of the holding element 245 is limited by the stud 250 and the dome 25. An electrical contact 301 is connected by a supply wire 302 to the electrical system 27. This contact 301 comprises a relief 303, by example a pin, engaged in a housing 307 of the stud 250. The contact 301 rests on the metal housing of the electrical system 27, which is supported on an upper electrode of the battery. Thus, the contact 301 is connected to this electrode via the metal casing of the electrical system 27. The displacement towards the receptacle 2 of the energy source 28 is limited by the base portion of the sub-capsule 215, and for example as illustrated by a relief 255 made by molding in one piece therewith.

In an exemplary embodiment, the base portion 215 of the sub-capsule carries a fixed electrical contact 330 connected by a power supply wire 331 to the electrical system 27. The displacement of the energy source 28 during the use of the device, when the dome 25 is pressed against the skin, causes the lower electrode 262 of the energy source 28 to press against the contact 330 carried by the base portion 215 of the sub-capsule, which allows the feeding of the electrical system 27 and the operation of it. A cover 280 can cover the dome 25 in the absence of use. Of course, many variations can be made to the invention without departing from the scope thereof.

For example, it is possible to modify the shape of the fixed contact 54, and in particular to give it a disc shape provided at two diametrically opposed locations of fastening fins 97, as illustrated in FIG. 10, this disc possibly also having in one region central recess 98 which electrically contact the upper electrode 53 of the stack.

It is also possible, as illustrated in FIG. 12, to make the contact 54 in the form of a single elastic tab, arranged in cantilever fashion.

The electrical system may be other than a vibrating source, and for example be a phototherapy device, comprising for example one or more LEDs having a wavelength chosen depending on the treatment to be performed. The electrical system may also be an electrophoresis system, a system for heating the skin or other keratin materials, for example by conduction, ultrasound and / or radiofrequency, a system for cleaning it, for example through the use of ultrasound. The electrical system can still be a system for detecting ambient UV radiation, skin or hair color, hydration and more generally any skin or capillary diagnostic system. The electrical system may include a user interface, if any. The device according to the invention can be integrated into an apparatus such as a sprayer or a diffuser. The electrical system can affect the nature and / or flow rate of the product being dispensed.

The electrical system may be intended to treat the dispensed product, for example to magnetize it. The electrical system can still supply a heating resistor for heating a surface intended to come into contact with the skin or other keratin materials. The device may comprise, if necessary, several rotary massage members. The distribution of the product may be effected otherwise than by pressure on a wall of the container, for example by means of a pump or a system for advancing a piston, as mentioned above. The expression "comprising a" should be understood as being synonymous with 25 "having at least one".
