Description

  The present invention relates to a containment application device for applying at least one cosmetic or skin product, for example a makeup product or a care product for the body, face or hair.

  A number of applicators with a porous applicator member such as a foam are known. Such an applicator is known in particular from US Pat.

  Although these applicator members are generally easy to use, they still have some drawbacks.

  First of all, in these applicator members, potentially some of the composition remains in the pores of the foam and cannot be applied. Therefore, the composition is lost. This is particularly noticeable when the foam is washed several times within the lifetime of the device,

  In addition, when the applicator member is made of foam, it has both the characteristics of being highly compressible for ease of use and the characteristics of being able to be attached to the device sufficiently robustly. It has proven difficult to do.

  Finally, in use, the foam can cause undesirable friction sensations.

  In addition, for containment application devices, it is known that the application surface is formed by a nonporous membrane having one or more orifices therethrough. Such devices are typically used in applying a deodorizing composition or massage composition. In the application of such compositions, the importance of the application state is less critical than in the case of make-up. This is because, in make-up, a relatively uniform coating is often required without causing any visible application defects.

  Patent documents 4 to 6 disclose such a type of device.

  In Patent Documents 4 and 6, the flexible membrane can be placed on the rigid portion, and a valve that can be opened by the pressure of the composition can be formed.

  In the said patent document 5, the membrane is mounted on the foam block. In a variant, it is mentioned that the applicator member can be formed from an additionally flocked foam.

  Finally, applicators intended to be particularly suitable for applying lipsticks are known. Such applicator devices are particularly disclosed in US Pat. In Patent Document 9, the applicator surface is formed by a flocking grid. The grid can be formed from a flexible material, which makes it easier to place the grid on the support portion. Such a grid is not configured such that it can be displaced relative to the support portion when applied.

  Finally, an applicator for applying a stain remover is known, which applicator comprises a looped fabric placed on a rigid support, for example as disclosed in US Pat. ing.

There is a need to improve the containment application device for applying the composition especially to the skin or hair.
US Pat. No. 6,773,187 US Pat. No. 6,715,951 US Patent Application 2003/0129016 US Pat. No. 5,727,892 US Pat. No. 5,199,808 US Pat. No. 3,618,825 US Pat. No. 3,807,881 US Pat. No. 5,131,773 US Pat. No. 6,745,781 Japanese Patent Laid-Open No. 5-28226 (1993)

In an exemplary embodiment of the invention, a containment application device is provided, the device comprising:
A reservoir containing at least one composition for application;
A support that is fixed relative to the reservoir at one or both of application of the composition and occlusion of the device;
-A non-porous membrane attached to the support, comprising at least one dispenser orifice for passing the composition through and further covering at least part of the outer surface by a flock portion Such as a non-porous membrane;
Comprising
The membrane cooperates with one or both of the support and reservoir to form an interior space for containing the derived composition.

  The membrane achieves one or both of the ability to deform (or the ability to deform relative to the support and / or reservoir) and the ability to displace relative to the support and / or reservoir. Can be one or both of a configuration that is flexible and a configuration that is attached to the support and / or reservoir, Based on the displacement, the volume of the interior space can be reduced by at least 0.1 milliliters (mL).

  Such a change in the volume of the internal space can increase the pressure slightly. Thereby, a composition can be derived | led-out more easily.

  Thereby, the dispenser orifice can be made relatively small. As a result, the composition can be prevented from suddenly flowing out when the device is turned upside down, and a sufficient amount of the composition can be made to reach the application surface that is ready for use. Can do.

  The volume reduction can be at least 0.5 mL, preferably at least 1 mL, more preferably at least 1.5 mL, and at least 2 mL, at least 3 mL, It can be.

  The volume reduction can be the result of deformation of the membrane, which can be flexible, or can be the result of displacement of the membrane when the membrane is rigid.

  In an exemplary embodiment, the membrane can be rigid and can be displaced by translation. In various exemplary embodiments, the membrane can be flexible and additionally can be displaced by translation.

  The membrane can be formed from a different material than the foam with open cells. Thus, the membrane does not have pores interconnected in all directions.

  The device can comprise at least one member that limits deformation of the membrane in use. This member can be fixed on the reservoir or can be molded integrally with the reservoir.

  The member can be flexible and can be bent upon application of the composition.

  The member can be, for example, a form of a fin that abuts against the inner surface of the membrane.

In an exemplary embodiment of the invention, a containment application device is provided, the device comprising:
A reservoir containing at least one composition for application;
A support that is fixed relative to the reservoir at one or both of application of the composition and occlusion of the device;
-A non-porous membrane attached to the support, comprising at least one dispenser orifice for passing the composition through and further covering at least part of the outer surface by a flock portion Such as a non-porous membrane;
Comprising
The membrane is flexible, the ability of the membrane to deform over at least a portion of the membrane (or the ability to deform relative to the support and / or reservoir), and the support and / or Attached to the support and / or reservoir in such a way that one or both of the ability to be displaced with respect to the reservoir can be achieved, whereby the membrane is at least 1.5 millimeters (mm, for example) ), Such as over a distance of preferably at least 3 mm.

  The support can form part of the reservoir, for example, can be defined by the neck of the reservoir, and / or the support can function to secure the membrane on the reservoir. The support can be molded with the membrane, and the support and the membrane are formed, for example, from different thermoplastic materials.

  The support can be a part that is mounted on the reservoir, or the support can be molded as an integral member to the reservoir.

  The device according to the present invention can overcome all or part of the above various drawbacks associated with foam applicator members. It has been found that the device according to the invention can be used comfortably in use, for example because the membrane can be deformed when in contact with the skin and / or because the membrane can be displaced. is doing.

  In one embodiment of the invention, the membrane is formed by molding with at least one duct in communication with the dispenser orifice. Such ducts can allow the composition to flow from the reservoir to the dispenser orifice, and avoid the accumulation of the composition below the membrane away from the dispenser orifice. This can reduce the loss of the composition and / or reduce the time required for the composition to reach the application surface. This also allows the composition to flow more easily through the dispenser orifice when the pressure increases below the membrane.

  Furthermore, the presence of such a duct can create a pressure drop between the reservoir and the dispenser orifice, if necessary. Thereby, the derivation speed | velocity | rate of a composition can be adjusted according to the property of a composition and / or according to the feature point of a to-be-processed area | region.

  Finally, due to the presence of the duct, an elastic return member can be provided below the membrane. The elastic return member is formed, for example, from a metal spring or from a foam or even from an air-air cushion and is protected from contact with the composition. The membrane can also be elastically deformable and can elastically return to its initial shape.

  In one embodiment of the present invention, the duct can slide along the inside or outside of the cylindrical member of the device. A cylindrical member can be formed with the said support body, for example. With such a slide, the membrane can be pressed relatively easily, and the space between the tubular member and the duct can be maintained substantially hermetically.

  If the composition has a particular color, the membrane can advantageously be formed as having substantially the same color as that color. In this case, for example, the flock portion can be white. When the floc portion is wetted by the composition, the white membrane with the flock portion does not appear to be stained by the colored composition, thereby improving the appearance of the membrane. When impregnated with the composition, a membrane color appears in the floc portion. The membrane can also be transparent or translucent. The floc portion can be colored and the membrane can be white.

  In one embodiment of the invention, the membrane can be formed by molding with a peripheral skirt. If possible, the height of the peripheral skirt can be, for example, 10 mm or more.

  To illustrate, such a peripheral skirt can function to secure the membrane on the device. In particular, the peripheral skirt can secure the membrane on the support.

  If the membrane is displaceable relative to the support, the peripheral skirt can further guide the membrane such that it can be displaced relative to the support.

  The peripheral skirt can be formed such that the entire membrane can be pressed against the support. For example, the peripheral skirt can be formed with an elastically deformable portion such as, for example, a bellows shaped. Alternatively, the peripheral skirt can comprise an elastic tab.

  The peripheral skirt can additionally rest on the bottom of the support and / or reservoir of the housing receiving the membrane.

  The membrane can be fixed to the support in various ways. For example, the membrane may be snapped onto the support, fitted to the support, held by a bent edge of the support, or held by an additional fixing member. It can even be fixed by adhesives or heat seals, and even fixed by deforming the membrane or support during heating or stamping of the support is there.

  The reservoir can have a flexible wall or a rigid wall.

  The reservoir can be provided with a pump. Alternatively, the reservoir can be provided with a piston and a drive mechanism for driving the piston.

  The reservoir can further be provided with a valve. And the derived | led-out composition can be accommodated in pressurization space, for example. The pressurization of the pressurizing space can be performed by, for example, a compressed propellant gas or a liquefied propellant gas.

  The membrane can have an outer surface that is concave or convex. At least one dispenser orifice can be located in the recess of the membrane or at the top of the membrane boss.

  The membrane may be provided with a shape that may have a generally circular symmetry, for example at the flock portion.

  For example, the distance of the deformation and / or the displacement of the membrane at the time of application may be, for example, 5 mm or more, and may be in a range of 5 mm to 15 mm.

  The membrane can be formed from a compressible material such as an elastomer. The membrane can also be formed from a relatively rigid material, for example if the membrane is configured to be displaceable relative to the support and / or the reservoir.

  The composition contained in the reservoir, if appropriate, can be in permanent communication with the dispenser orifice without any flow reduction mechanism between the reservoir and the membrane. In a variant, at least one blocking mechanism can be provided for blocking communication between the reservoir and the dispenser orifice. This can prevent accidental leakage of the composition when the device is not in use, such as when the device is carried.

  The composition can have a sufficiently small viscosity that it can be delivered to the floc portion by capillary action, such as, for example, after turning the device upside down.

  In one embodiment of the present invention, the proportion occupied by the dispenser orifice can be less than 75%, preferably less than 30%, of the area of the membrane covered by the floc portion. .

  The occupation ratio of the dispenser orifice can be selected according to the viscosity of the composition.

  Illustratively, in cross section, the dispenser orifice can have a maximum dimension of 2 mm or less, for example a maximum dimension in the range of 0.4 mm to 1.8 mm, preferably It can have a maximum dimension in the range of 8 mm to 1.5 mm.

  The shape of the dispenser orifice can additionally be circular. This can increase the amount of composition retained by capillary action within the dispenser orifice.

  The dispenser orifice or orifices can be permanently open, or can be closed at rest and open by the pressure of the composition. The pressure of such a composition may be due to the user pressing on the reservoir wall, or may be due to the presence of a piston or, for example, compressed gas or liquefied. It is attributed to some other means that can pressurize the composition, such as a gas.

  The support can be configured to occlude the reservoir.

The surface covered by the flock portion can have a surface area of 175 square millimeters (mm ² ) or greater. Thereby, it can be made suitable for application with respect to a body or a face.

  In particular, in the region covered with the flock portion, the thickness of the membrane can be in the range of 0.2 mm to 5 mm.

  For example, the length of the bristles (or bristles) constituting the flock portion is in the range of 0.2 mm to 2.5 mm, for example, about 1.3 mm. The diameter of the coarse hair can be in the range of 1 denier to 35 denier, for example. The floc portion can be formed such that the desired distribution of the composition is obtained depending on the properties of the composition.

  Thus, the membrane can have flock portions composed of different types and / or different thicknesses and / or different lengths of bristles. This can affect the capillary action, smoothness, flow rate or derivation of the composition on the application surface. If appropriate, some bristles can exhibit wear characteristics, for example by being made more rigid.

  The rough hair of the membrane and / or flock portion can be magnetic and / or can be treated with an antimicrobial agent.

  The membrane and / or floc portion can be formed as having electrical conductivity.

  Where appropriate, the membrane can be provided with at least one irregular portion so that the hair can be massaged, the hair can be handled or the hair can be treated.

  One or more dispenser orifices may additionally be located in the middle of the membrane. The dispenser orifice can additionally be located on the axis of the device.

  In one embodiment of the invention, the support can be mounted on a reservoir and the membrane can comprise a rim that is clamped and secured between the reservoir and the support. The rim may comprise a groove or an annular lip, such as cooperating with a corresponding lip or corresponding groove of the support or reservoir. Thereby, sealing performance can be further improved.

  In the exemplary embodiment, the membrane can be mounted at least partially on the engagement portion. The engaging portion can be the above-described support and can be formed of a material that is more rigid than the material forming the membrane.

  The engagement portion can include at least one fin. The fins are substantially matched to the inner shape of the membrane.

  The engaging portion can include a plurality of fins. The tips of these fins can be free or can be connected to each other by an annular portion. The annular portion can form a passage for the composition.

  The device can comprise an occlusion cap that can cover the membrane in the occluded state of the device. The closure cap may comprise a lip that locks against the membrane along a line that surrounds one or more dispenser orifices.

  The cap, by cooperating with the support or reservoir, can press the membrane between the occlusion cap and the support or reservoir along a line surrounding the dispenser orifice.

  The cap can include an inner surface that can be substantially adapted to the outer shape of the membrane. This can improve the sealing performance and / or reduce the risk that the composition will accumulate on the floc portion when the device is not in use. The cap may include one or more holes that allow at least one flock portion of the membrane to communicate with external air when the device is closed. The flock portion can be dried. The cap can alternatively be fixed on the support and / or on the reservoir in a completely sealed manner.

  The device can be provided with a vibration source (or vibration generator). The vibration source can be removable or permanent. The vibration source can be operated by the user.

  Illustratively, the presence of vibrations allows the user to change the amount of composition applied on the stratum corneum as desired. Thereby, for example, the color of the foundation can be changed. If appropriate, the frequency of the vibration source can be made variable. The frequency is adjusted by the user depending on the desired application conditions.

  The present invention further provides a method of treating keratinous material, and in particular, a method of applying makeup. In the method according to the invention, the composition is applied using a device as described above.

  The composition can be applied in the form of a layer having a substantially constant thickness.

  The application surface can easily slide over the skin and releases little impurities due to the application surface.

  The non-porous membrane can reduce the risk of dust accumulation.

In an exemplary embodiment of the invention, a containment application device is provided, the device comprising:
A reservoir containing at least one composition for application;
A support that is fixed relative to the reservoir at one or both of application of the composition and occlusion of the device;
-A non-porous membrane attached to the support, comprising at least one dispenser orifice for passing the composition through and further covering at least part of the outer surface by a flock portion Such as a non-porous membrane;
Comprising
The ability of the membrane to cooperate with one or both of the support and the reservoir to form an internal space for containing the composition, and the ability of the membrane to deform (or relative to the support and / or reservoir) And / or a structure that is flexible so as to achieve one or both of the ability to be deformable with respect to the support and / or the reservoir, and the support. And / or one or both of the configurations attached to the reservoir, and based on membrane deformation and / or displacement, the volume of the internal space can be reduced, It extends transverse to the longitudinal axis of the device over a distance of 15 mm or more. Such a membrane with a flock portion can be particularly suitable for handling a large area of the body or face.

In an exemplary embodiment of the invention, a containment application device is provided, the device comprising:
A reservoir containing at least one composition for application;
A support that is fixed relative to the reservoir at one or both of application of the composition and occlusion of the device;
-A non-porous membrane attached to the support, comprising at least one dispenser orifice for passing the composition through, and further having at least a part of the outer surface extending to the peripheral part by the flock part A non-porous membrane, such as coated;
Comprising
The membrane may be capable of deforming the peripheral portion (or may be capable of deforming the peripheral portion relative to the support and / or reservoir), and the peripheral portion may be displaced relative to the support and / or reservoir. Is attached to the support and / or reservoir in such a way that one or both of the above can be achieved.

  Illustratively, the peripheral portion can be formed by a tubular skirt. For example, the outline of the peripheral portion made of the flock portion can be circular.

  The present invention can be understood more clearly by reading the following detailed description, given by way of example only, and not by way of limitation, with reference to the accompanying drawings, in which:

  The device 1 shown in FIGS. 1 and 2 includes a reservoir 2. The reservoir 2 contains at least one composition P, for example a cosmetic product, in particular a makeup or care product for the skin or hair. The device 1 further comprises a dispenser head that forms an application surface 3 for applying the composition P to the stratum corneum.

  For example, the composition P may be blusher, foundation, lipstick, sunscreen, care product, hair treatment, slimming agent or self-tanning agent.

  The reservoir 2 includes a body 7 and a neck 8 connected to the body 7. A support 10 is mounted on the neck 8. The support 10 functions to hold the membrane 12. The outer surface of the membrane 12 is at least partially covered by a flock portion 13 that forms the application surface 3.

  The device 1 further includes a closure cap 4. In this embodiment, the closing cap 4 can be screwed to the thread 5 of the support 10.

  The membrane 12 is formed from a non-porous material, for example, an elastomer such as a thermoplastic elastomer; a nitrile-based elastomer or a silicone-based elastomer; a polyurethane; an ethylene propylene terpolymer rubber (EPDM). );

  Among the thermoplastic elastomers, the following elastomers can be mentioned. That is, polyethylene (PE); polystyrene (PS); polyethylene terephthalate (PET); polyurethane (PU); polyvinyl chloride (PVC); ethyl vinyl acetate (EVA). Suitable elastomers are known in particular under trade names such as HYTREL®, PEBAX® (polyether block amide) and SANTOPRENE®.

  In the embodiment being considered, the flexibility of the membrane 12 allows the membrane 12 to deform when it contacts the surface to be treated during application.

  The membrane 12 is advantageously made washable. In addition, the membrane 12 is detachable. This allows the user to remove the membrane 12 from the reservoir and clean it, and then reattach the membrane 12.

  A plurality of orifices 15 are formed through the membrane 12. Thereby, the composition P can reach the application surface 3.

  To illustrate, the plurality of orifices 15 are formed by molding together with the molding of the membrane 12. However, the plurality of orifices 15 can also be formed by drilling after the membrane is manufactured.

  The lower end of the orifice 15 opens into the duct 18 of the membrane 12. The duct 18 is engaged with the cylindrical member 19 of the support 10 in the longitudinal axis X direction.

  Illustratively, the duct 18 is formed by molding together with the remainder of the membrane 12.

  Duct 18 has a cross-sectional shape, preferably circular.

  The base of the cylindrical member 19 is connected to the lateral wall 21 of the support 10. A peripheral edge portion 22 is connected to the lateral wall 21. The peripheral portion 22 functions so that it can be fixed to the neck 8 of the support 10 by a technique such as snapping.

  The presence of the duct 18 may reduce the amount of composition entering the annular chamber 30 formed outside the duct 18 and outside the tubular member 19 inside the device, or such Advantageously, the composition can be prevented from entering the annular chamber 30.

  The degree of deformation of the membrane 12 depends on the force applied to the membrane. In the embodiment under consideration, the membrane 12 is a receptacle (or reservoir) 2 at least in its central region, for example when the user presses the membrane 12 with his finger, as shown in FIG. Can be deformed by a distance d of at least 1.5 mm.

  When deformed, the duct 18 can slide over the tubular member 19 without causing any clearance and preferably in a sealing manner.

  Further, the membrane 12 can be deformed in the lateral direction in the peripheral region composed of the flock processing region. The membrane 12 is particularly suitable for treating large areas of the body or face. When the membrane 12 is observed from above, the flocking region extends over a distance k of 15 mm or more in the direction orthogonal to the axis X.

  The thickness e of the membrane 12 is, for example, in the range of 0.2 mm to 5 mm, and preferably in the range of 0.2 mm to 2 mm.

  The membrane 12 can be held on the support 10 by various methods.

  In the embodiment under consideration, the membrane 12 is provided with a mounting skirt 26 at its periphery. The attachment skirt 26 has an uneven portion 27. The uneven portion 27 is suitable for being snapped to a corresponding portion formed on the peripheral portion 22 of the support 10.

  For example, the uneven portion 27 is an annular flange as shown in FIG. This annular flange is configured so that it can be snapped into the corresponding groove 28 of the support 10.

  When using the device 1, the user can turn the device upside down to place the dispenser in an inverted state. Thereby, the composition P can flow through the cylindrical member 19 by gravity, and the composition P can reach the dispenser orifice 15.

  Depending on its viscosity, the composition P can diffuse by capillary action into the flocked part 3 after passing through the orifice 15.

  Due to the deformability of the membrane, the volume of the internal space 29 that contains the composition and is defined by the membrane 12 can be changed. Thereby, the pressure can be increased slightly, and the composition held in the orifice 15 by capillary action or the composition held in the vicinity of the orifice 15 by capillary action can be applied to the application surface. Can be pushed towards

  The change in the internal volume 29 is advantageously at least 0.1 mL, preferably at least 0.5 mL, and can even be at least 1 mL.

  In addition, since the deformability of the membrane 12 does not need to maintain the initial shape during use, and because it can be adapted to the shape of the region to be processed, the usability of the device is improved. It has been very comfortable.

  In the modification shown in FIG. 4, the membrane 12 is formed having a plurality of flexible tabs 35 positioned below the attachment skirt 26. In the embodiment under consideration, as shown in FIG. 5, the tabs 35 have a downward slope and are inclined slightly inward. The tab 35 can bend. Thereby, in use, the attachment skirt 26 can be displaced toward the bottom of the receptacle (or reservoir). The tab 35 can have a cross section that decreases as it goes toward the lateral wall 21 of the support 10 to be abutted. In variations (not shown), the tabs may instead have a cross-sectional shape that varies in various ways. Alternatively, the tab can even have a portion with a substantially constant cross-sectional shape.

  In the embodiment of FIG. 4, the membrane floc portion can be additionally deformed when applied. Thus, it can be advantageous that both the flexible tab 35 and the membrane floc portion are deformable.

  In the embodiment of FIG. 6, the mounting skirt 26 is formed with a deformable portion 37 in the form of a bellows. In a modification (not shown), the attachment skirt 26 is formed having both a bellows 37 and a flexible tab 35.

  In the embodiment of FIG. 7, the entire membrane 12 can be displaced toward the bottom of the receptacle (reservoir). For example, the entire membrane can slide downward by the distance w. In such variations, the membrane 12 may not be flexible.

  The mounting skirt 26 can be formed with an uneven portion 39 such as an annular flange. The support 10 can include a groove 38 having a height that is greater than the height of the annular flange 39. Thereby, the membrane 12 can be displaced in the axial direction.

  An elastic return member can be disposed in the chamber 30. The elastic return member can be in the form of a spring 42 as in the embodiment of FIG. Alternatively, the elastic return member can be in the form of a foam block 50 as shown in FIG.

  The membrane 12 can also be formed as a single member together with the elastically deformable return member 51 by molding a plastic material. The return member is configured, for example, such that it can be locked against the wall of the receptacle (reservoir). Alternatively, the return member is configured to be attached to the support 10 by an attachment portion 52 as shown in FIG.

  In a variation (not shown), the membrane is formed as a single member with the support and / or reservoir, such as by a dual injection of two materials. The membrane can thus be formed from a flexible material by molding.

  In the embodiment of FIG. 9, the membrane 12 does not include the duct 18 in the above embodiment, and the mounting skirt 26 slides in a substantially sealed manner, for example, within the neck 53 of the support 10. It is configured as possible.

  The membrane 12 can be formed in various initial shapes, for example, depending on the properties of the composition and depending on the region to be treated.

  For example, in the region covered with the flock portion 13, the membrane 12 can be generally concave as shown in FIG. 10. In this case, for example, the orifices 15 are arranged radially toward the inside of the duct 18 at the bottom of the concave region.

  Due to the overall concave shape, the composition can be easily accumulated in the rough hair of the flock portion by capillary action, and the skin or hair can be easily dried by capillary action.

  In the modification of FIG. 11, the concave region of the membrane 12 is limited to the region of the membrane 12 that faces the inside of the duct 18.

  In the embodiment of FIG. 12, the membrane 12 has a generally convex shape over the portion covered by the flock portion 13. In the embodiment of FIG. 13, the convex region of the membrane 12 is limited to the region of the membrane 12 that faces the inside of the duct 18.

  In the embodiment of FIG. 14, the membrane 12 has a stepped shape. In this case, the part 60 protrudes from the peripheral part 61. The dispenser orifice 15 is disposed substantially at the junction of the portions 60 and 61.

  The dispenser orifice 15 can be dispensed onto the application surface by various techniques.

  Illustratively, the dispenser orifice 15 can be collected in a central portion, as shown in FIG. 15, or can be arranged in a plurality of concentric circles, as shown in FIG. As shown, it can be grouped into multiple clusters.

  The dispenser orifice can also be in the form of a slot. For example, as shown in FIG. 18, it can be a plurality of slots connected to each other at one end, or as shown in FIG. Or it can be a single slot. The slot can have a rectangular shape or can have a keyhole shape with a portion 63 as shown in FIG. Portion 63 can be lifted by the pressure of the composition. Portion 63 is attached to the membrane by a material bridge 64 at rest. The dispenser orifice can also be formed by drilling a grid.

  One or more dispenser orifices 15 may be closed during rest (ie, when not in use). One or more dispenser orifices 15 can be opened by the pressure of the composition.

  The dispenser orifice may also be permanently open as shown in FIGS. The dispenser orifice can have a circular cross-sectional shape, as shown in FIG. 21, or a polygonal cross-sectional shape, eg, a square as shown in FIG. 22, or As shown in FIG. 23, it can have a cross-sectional shape of a rhombus shape. A polygonal cross-sectional shape can increase the ability of the composition to retain due to capillary action.

  When the membrane 12 is observed from above, the membrane can have various shapes. For example, as shown in FIG. 24, it can have a circular shape. The membrane 12 can also have an oval shape as shown in FIG. 25, and can also have a polygonal shape such as a triangular shape as shown in FIG. As shown, it can have a square shape and can have a substantially rectangular shape, as shown in FIG.

  The membrane 12 can also have a substantially kidney-like shape as shown in FIG. 29 when observed from above.

  As shown in FIG. 30, the membrane 12 may have a dome shape as a whole. In that case, the orifice 15 is arranged substantially at the top of the dome.

  The dome shape may be circular such that it is symmetric about the axis X as in the embodiment of FIG. The dome shape can also be a pyramid shape as shown in FIG.

  Regardless of the shape of the membrane, the one or more dispenser orifices 15 can be located at the top of the membrane or can only open on the side of the membrane 12, as shown in FIG. it can.

  In this figure, it can be seen that the dispenser orifice 15 is located at a predetermined distance r from the top of the membrane 12. This distance r is, for example, several millimeters.

  The membrane 12 can be formed as having a rim 66 at the periphery. 33, the cap 4 can be formed so that the cap 4 can be engaged with the rim 66 when the cap 4 is disposed on the reservoir 2 in a predetermined manner. Thereby, the device can be closed in a sealing manner.

  It can also be seen in this figure that the mounting skirt 26 can cover the outer surface of the support 10. The outer surface is formed by the top of the reservoir 2, for example.

  As shown, the duct 18 can be inserted into the tubular member 19.

  In the modification of FIG. 34, the membrane 12 is formed with a rim 70. The rim 70 is sandwiched between the neck 8 of the reservoir 2 and the support 10 attached to the reservoir 2.

  To illustrate, the neck 8 is formed with an annular rib 71. The support 10 is formed with a corresponding annular rib 72. Thereby, the rim | limb 70 can be pinched effectively.

  The cap 4 can include a seal skirt 73 that is locked to the support 10 when the cap 4 is disposed at a predetermined position on the reservoir 2 as illustrated. In this figure, it can be seen that the membrane 12 is formed without the duct 18.

  In the modification of FIG. 35, the membrane 12 is formed having a plurality of uneven portions 80. These uneven portions 80 are covered by the flock portion 13. These uneven portions 80 are intended to handle hair, for example. The membrane 12 can engage with the top end 82 of the tubular member 19. Thereby, only the part located in the radial direction between the attachment skirt 26 and the duct 18 in the membrane 12 can be deformed during use.

  The cap 4 can be formed as having a lip 85. The lip 85 can be locked to the membrane 12 on the surface located on the side opposite to the cylindrical member 19 when the cap 4 is disposed in a predetermined manner. Thereby, the membrane 12 can be clamped (or fixed) between the tubular member 19 and the lip 85. Therefore, it is possible to reduce the risk that the composition overflows onto the portion of the membrane flock surface that is located radially outside of the lip 85. Thereby, if appropriate, an air vent 90 can be formed in the cap 4 as shown in FIG. Thereby, the flock part 13 located on the radially outer side than the lip 85 can be dried more easily.

  In a variation (not shown), the cap includes a portion configured to lock against the membrane. This portion can press the membrane in the region of the dispenser orifice, thereby preventing the composition from leaking through the dispenser orifice.

  One or more dispenser orifices 15 can be in permanent communication with the interior space of the reservoir containing the composition. This configuration is not essential. The device can include a mechanism that can block fluid communication between the one or more dispenser orifices 15 and the interior space of the reservoir.

  In the embodiment of FIG. 37, the support 10 can move relative to the reservoir 2 between a first position and a second position. Here, the first position refers to the internal space of the reservoir containing the composition through the annular passage 92 defined by the tubular member 19 and defined by the nozzle 96 attached to the reservoir 2. The position is such that the composition can flow to the dispenser orifice 15, and the second position is a position where the support 10 closes the passage 92.

  The support 10 is movable on the neck 8 of the reservoir 2. The support 10 is firstly provided by a collar 97 formed at the top end of the neck 8, and secondly by one or more irregularities such as teeth or annular flanges formed on the support. , Held on the neck 8.

  In the embodiment of FIG. 37, it can be observed that the cylindrical member 19 can be formed as a truncated cone. Thereby, when the nozzle 96 presses the cylindrical member 19, a device can be obstruct | occluded more easily.

  The transition from the open position to the closed position and the transition from the closed position to the open position can be carried out, for example, by the support 10 that can be translated, or, in a modified example, can be rotated. The support 10 can be implemented. In the latter case, at least one of the support and the reservoir 2 is provided with an inclined portion that can convert such a rotational movement into an axial translation of the cylindrical member 19 relative to the nozzle 96. Yes.

  As shown in FIG. 38, a blocking mechanism for blocking communication between one or more dispenser orifices 15 and the interior of the reservoir can also be constituted by a disk 100. The disk 100 can move the support 10 between an open position and a closed position. The disc 100 can be snap-fixed to the support 10 and can include a portion 101 configured to close an orifice 103 that allows the dispenser orifice 15 to communicate with the interior of the reservoir 2. .

  In this embodiment, the duct 18 is locked to the cylindrical member 105 of the disk. The rotation of the cylindrical member 105 is guided by, for example, the cylindrical member 19 of the support 10. The membrane 12 can rotate with the disc 100.

  As shown in FIG. 38, the cap 4 can be formed as having a lip 110. The lip 110 is locked to the membrane 12. Thereby, the risk that the composition overflows onto the flock portion 13 located radially outside the lip 110 can be reduced.

  FIG. 39 shows another embodiment in which the support 10 comprises a lateral wall. An orifice 115 is formed through the lateral wall. These orifices 115 open between two skirts 118 and 119 that are coaxial with each other.

  The disk 120 is provided for the support 10 and includes two skirts 123 and 124. The skirts 123 and 124 extend from the lateral wall 138 and are locked to the skirts 119 and 118, respectively. A permanent seal is obtained by locking the skirt 123 and the skirt 119.

  A passage 130 is provided so that the angular position of the disk 120 with respect to the support 10 can be a predetermined one. The passage 130 enables supply to the space 131 below the membrane 12. The membrane can be secured on the disk 120 by the disk's folded edge 136. The bent edge clamps (fixes) the peripheral portion of the membrane 12 against the lateral wall 138.

  In all the embodiments described above, the user can turn the device upside down when deriving the composition based on the viscosity of the composition. Thereby, the composition flows out by gravity. The user can also shake (shake) the reservoir 2.

  The user can deform the membrane and / or displace the membrane in a manner that can facilitate the passage of the composition through the dispenser orifice.

  Where appropriate, the reservoir can be formed as having a flexible wall. This allows the user to flow the composition through the dispenser orifice by pressing the flexible wall to reduce the reservoir volume. For example, the reservoir 2 may be a flexible tube.

  As shown in FIG. 41, the reservoir 2 can also be formed as having a piston 140. The piston 140 can be driven by a screw 141 and a knob 142. By turning the knob 142, the user can cause the composition to flow through the reservoir neck 8 toward the dispenser orifice 15.

  The membrane can have a shape that is symmetric about an axis Y that forms an angle α with respect to the longitudinal axis Z of the reservoir 2, as shown in FIG.

  The device can be formed with a vibration source. For example, the vibration source includes an electric motor 160 disposed in the compartment 161 of the reservoir 2 as shown in FIG. The compartment 161 is insulated from the compartment containing the composition. The electric motor 160 can cause vibration by driving the off-center weight 162.

  The electric motor 160 can be powered by one or more batteries, such as a button-type battery 163 in particular.

  A switch 164 may be provided so that the motor 160 can be activated.

  The reservoir 2 can have a removable bottom 166. Thereby, the battery 163 can be replaced.

  The vibration can change the thickness of the applied layer and / or change the flow rate of the composition and / or stimulate the treated area as desired. .

  In a variant, the vibration source can also be removable. Alternatively or additionally, the vibration source may be capable of changing the vibration frequency by the user.

  As shown in FIG. 44, the device can also be formed with electrodes 170. The electrode 170 may be connectable via a switch 172 to a power source 165 such as a battery of 1.5 volts (V) to 9V, for example. The membrane can be formed from an electrically conductive material or an electrically insulating material, for example, depending on the arrangement of the electrodes.

  The membrane 12 may not be fixed with respect to the reservoir 2 at the time of application. However, as shown in FIG. 45, the membrane 12 is fixed to the reservoir in the closed state. In this figure, it can be seen that the closure cap of the reservoir can be formed with a cylindrical member 180 that functions as a support for the membrane 12. The support 10 can form a housing 190 in which the membrane 12 is received. At the bottom of the housing, a plurality of orifices 195 are open, which allows the composition to flow toward the membrane 12.

  When the device is turned upside down with the device occluded, the composition P will flow through the orifice 195 and further through the orifice 15 of the membrane 12. As a result, the composition P accumulates in the chamber 196 formed inside the cylindrical member 180. The composition thus stored constitutes a reserve. Thereby, the usable time of an applicator can be lengthened.

  In addition, when the membrane 12 is deformed, a pumping effect can be caused.

  The composition can be absorbed when the membrane 12 is relaxed. Such relaxation causes an increase in the volume of the chamber 196.

  Due to the deformation of the membrane, the pressure can also be increased. This allows the composition present in the chamber 196 to be led through the dispenser orifice 15 by reducing the volume of the chamber 196.

  FIG. 46 shows a modification of the device of FIG. In this modification, the membrane 12 is mounted on a holding member 200 that is movable with respect to the cap 4.

  The holding member 200 includes a lateral wall 201. The lateral wall 201 locks one end of the spring 202. The other end of the spring 202 is locked to the cap 4.

  The device shown in FIG. 47 includes a membrane 12 having an annular rim 213 at the peripheral portion. The annular rim 213 is engaged between the neck of the reservoir 2 and the corresponding part of the support 10.

  The membrane rim 213 includes an annular groove 210. The support 10 is provided with an annular lip 211 engaged in the groove 210. Thereby, this can improve the seal where the membrane is mounted on the reservoir 2 and the seal where the membrane is mounted on the support 10.

  This figure further illustrates the possibility of providing stiffening fins 220 on the inner surface of the membrane 12. As shown in FIG. 48, these fins are arranged in an annular shape around the axis X.

  The presence of the fins 220 can increase the strength of the membrane 12 when applied.

  FIG. 53 shows a modification. In this variation, the device includes an engaging portion 280.

  The engaging portion 280 is formed of, for example, a non-elastomeric plastic material and can play the same role as the support 10 in the various embodiments described above.

  The material forming the engaging portion can be more rigid than the material forming the membrane.

  In the illustrated embodiment, the engagement portion 280 is attached to the reservoir and includes an annular portion 270. An annular bead 273 is provided on the annular portion 270. The annular bead 273 is engaged in the corresponding groove 272 of the membrane 12.

  The engagement portion 280 can include an uneven portion 282 such as a screw thread. The uneven portion 282 allows the cap 4 to be attached.

  In the illustrated embodiment, the engaging portion 280 is attached to the neck 8 of the receptacle (reservoir) 2, and the membrane 12 is attached to the engaging portion 280. However, the engagement portion 280 can be attached to the neck 8 and the membrane 12 can be attached to the engagement portion 280 by using at least one additional member.

  The engaging portion 280 includes a member that restricts deformation of the membrane. Such a member can be, for example, a flexible fin 275 that contacts the inner surface of the membrane 12.

  For example, as shown in FIGS. 54 and 55, the fins 275 can be annularly arranged around the axis X. The number of fins can be six.

  FIG. 54 shows an embodiment in which the fin 275 includes a proximal end 276 that is connected to the annular portion 270 and a free distal end 277.

  The fins 275 can be of constant width or not. For example, the base end of the fin can be wider than the tip.

  FIG. 55 shows a modification in which the tip portions 277 of the fins 275 are connected to each other by the annular portion 279.

  The annular portion 279 can have a plurality of openings. These openings can coincide with the orifice 15.

  In a variant not shown, the fins 275 can be formed on the neck 8 of the receptacle (reservoir).

  The presence of the fins 275 can improve the ability to maintain the shape of the membrane 12 when applied. This is because it can limit the deformation of the membrane.

  The cap 4 can have an inner surface 225 that substantially conforms to the shape of the flocked region of the membrane 12. Thereby, the volume of the space formed between the membrane 12 and the cap 4 in the closed state of the device can be reduced. The cap 4 can be formed as having an annular seal lip 226. As shown in FIGS. 47 and 53, the annular seal lip 226 can lock the annular protrusion 229 of the support 10.

  As schematically shown in FIGS. 49 and 50, multiple devices formed in accordance with the present invention can be associated with each other within a set 230 or 240.

  The set 230 includes two reservoirs 2a and 2b and two membranes with flock portions corresponding to the reservoirs 2a and 2b, respectively. The reservoirs can be connected to each other by a connecting member 231. The connecting member 231 also functions as a closing cap for each reservoir.

  For example, the connecting member 231 includes screw threads 232 and 233 for being screwed to the reservoirs 2a and 2b, respectively.

  Illustratively, the reservoirs 2a, 2b contain two compositions having different awning characteristics or different sun protection indices. The two compositions can be applied sequentially, for example as a base coat and a top coat.

  In set 240, membranes with flocked portions are located on both sides of the device. These membranes can be covered by respective caps 4a, 4b.

  The reservoir 2 is common to both membranes with flock portions. By way of example, the reservoir 2 comprises two compartments containing different compositions to be applied by the respective membrane. Each membrane is associated with a corresponding cap 4a, 4b.

  In a variant (not shown), the reservoir 2 comprises a single composition. And the membrane with a flock part has a mutually different shape. For example, one membrane is suitable for handling a body other than the face, and the other membrane is suitable for handling the face.

  In the modification of FIG. 51, the reservoir 2 is in a compact form. The reservoir 2 can be closed by a lid 260. In the embodiment considered, the lid 260 is hinged to the reservoir 2. Alternatively, the lid 260 can be attached to the reservoir 2 by various other techniques. For example, it can be screwed or snapped to the reservoir. The composition is taken from the membrane 12, for example, by pressing the membrane with a finger. By deforming the membrane, the inner volume below the membrane can be reduced and the resulting increase in pressure can be retained by capillary action in the orifice 15 towards the outer surface of the membrane. To illustrate, the composition can be collected after shaking the reservoir.

  The invention is not limited to the various illustrated embodiments.

  Various features in the various embodiments described above can be combined with each other in the non-illustrated embodiments.

  For example, a vibration source can be attached to any device described above.

  The illustrated membrane can be attached to the illustrated reservoir.

  The dispenser orifice can be arranged in any manner in FIGS.

  The cross-sectional shape of the dispenser orifice 15 can be as shown in FIGS. The same applies to the shape of the membrane with a flock portion in plan view.

  The vibration source can be attached to the support.

  In all embodiments, if the composition is colored, the membrane can advantageously be formed as having substantially the same color as the composition. The flock portion can be white. When the floc portion is wetted by the composition, the color of the membrane can appear. This makes it more difficult to visually recognize the composition on the membrane, thereby improving the appearance of the device.

  The membrane can be formed such that it can be deformed not only along the axial direction of the housing receiving the membrane, but also in a direction perpendicular to such axial direction.

  The expression “comprising” should be understood as synonymous with “comprising at least one” unless otherwise specified.
