  Other objects, features, and advantages of the present invention will become apparent upon reading the following detailed description of the preferred embodiments, which are not intended to limit the invention in any way, but merely as examples, with reference to the accompanying drawings. Will.

  FIG. 1 schematically shows a rough surface A on an enlarged scale. The surface A is formed by, for example, a sandpaper or a material surface having particles fixed by a binder such as cement.

  The negative mold E is formed from a rough surface A as shown in FIG. For example, it is formed of an elastomer such as a silicone polymer.

  Thereafter, by using this negative mold, a mold M is formed as shown in FIG.

  As shown in FIG. 4, the mold M has a surface that substantially reproduces (or duplicates or duplicates) the surface roughness of the rough surface A.

  As shown in FIG. 5, the elastically deformable synthetic material forming the cleaning member is molded while being in contact with the mold M. After the molding, the elastically deformable material has a cavity C so as to exhibit a surface S having an undercut as shown in FIG.

  To illustrate, the elastically deformable synthetic material is a thermoplastic or curable (or vulcanizable) elastomer. For example, but not limited to, silicone polymer, ethylene propylene diene monomer (EPDM) rubber, latex, polyurethane elastomer, polyethylene, polyether, polystyrene, polyvinyl acetate (PVA), polyvinyl chloride (PVC), styrene ethylene styrene (SES) or styrene ethylene butylene styrene (SEBS).

  This elastomeric material is different from a foam (or foam) having open cells, semi-open cells or closed cells.

  The size of the cavity C depends on the size of the original rough surface A. This is also true for the cavity distribution. The distribution can be uniform or non-uniform.

The maximum dimension d _max of the cavity C is, for example, 5 mm or less, or even 2 mm or less.

  7 and 8 show the skin cleaning device 1. The device 1 includes a handle 2 having a head 3. The head 3 is provided with a skin cleaning member 4.

  The cleaning member 4 has a surface 5 that is used to wash the skin. As described above, the surface 5 is formed in contact with the mold M that reproduces the unevenness of the rough surface A.

  Thus, the cavity C of the cleaning surface 5 presents a surface S with an undercut, as schematically shown in FIG.

  In the example shown in FIG. 7, the cleaning member 4 is solid and is fixed to the surface 8 of the head 3. The surface 8 forms an angle α with the longitudinal axis X of the handle forming body 9 of the handle 2. In this example, the cleaning surface 5 is located on the same side as the axis X. This can improve ergonomic cleaning, particularly with respect to the face.

  For example, the cleaning member 4 is fixed to the surface 8. However, in a variant, the cleaning member can be fixed by other techniques. For example, fixing by heat sealing, overmolding, mechanical fixing such as screwing or snapping, or fixing by means of a Velcro (registered trademark) type hook and loop. Can do.

  The cleaning member elastomeric material forming the cleaning surface 5 is advantageously selected as having sufficient flexibility. Thereby, as shown in FIG. 8, the user can deform the cleaning surface 5 by applying a slight pressure with a finger.

  The cleaning surface 5 may have a shape that bulges as a whole. The bulge is, for example, substantially spherical or elliptical.

  The cleaning surface 5 can further have a plurality of facets (or subdivision surfaces) 11 as shown in FIG.

  The cleaning surface 5 can have substantially the same surface roughness throughout. Alternatively, in a variant, the cleaning surface 5 can have a plurality of regions with different characteristics, for example different surface roughness.

  Thus, by way of example, the facets 11 in the example of FIG. 9 can have the same surface roughness or different surface roughness. If appropriate, the latter configuration allows the user to provide a surface roughness and / or roughness that corresponds to the process to be performed, for example, stripping or removing deposits of the composition from the cleaning surface. The possessed region can be selected.

  7 and 8, no opening is formed in the head 3 and the handle. In the modification, the head 3 can be opened. Thereby, in particular, as shown in FIGS. 10 to 13, the head 3 can be formed as a frame.

  In this case, the cleaning member 4 can be in the form of a membrane, and the peripheral edge of the membrane can be fixed to the frame 3. If appropriate, the user can press the surface 13 of the membrane located on the opposite side of the cleaning surface 5. Thereby, as shown in FIG. 13, the membrane can be deformed, and thereby, for example, the membrane can be stretched so as to change the degree of contact between the cleaning surface 5 and the skin, or the skin. A greater pressure can be applied to the.

  Advantageously, due to the flexibility of the membrane 4, as shown in FIG. 12, the membrane can be deformed so as to be in contact with the body region that is to be processed or in contact with the surface region that is to be processed. Can do.

  When the cleaning member 4 is fixed to the handle 2 by snapping as shown in FIG. 14, the peripheral edge of the cleaning member 4 can snap into the annular bead 16 of the frame 3. A configured annular groove 15 may be provided.

  In the example of FIG. 14, the cleaning member 4 is formed as having a recess 17 on the surface opposite to the cleaning surface. In a modification, the cleaning member 4 can be formed without such a recess, as shown in FIG.

  The cleaning member 4 can be formed as an elastomer material forming a single member. Alternatively, in a variation, the cleaning member 4 can include a support member for supporting the elastomeric material, as shown in FIG. The support member is formed from a more rigid material.

  Illustratively, the cleaning surface 5 is formed by injection molding of two materials. Thereby, the membrane integrated with respect to the support ring 19 is formed. The support ring 19 can be fixed to the frame 3 in a detachable manner if appropriate. In this example, the support ring 19 can be engaged with the rim 20 of the frame.

  In the example of FIG. 17, it can be seen that the cleaning member 4 can be secured directly to the frame 3 by snapping in a manner different from that shown in FIGS. In this example, the frame 3 has an annular groove 20, and a rim 21 formed on the peripheral edge of the cleaning member 4 can be engaged with the annular groove 20.

  FIG. 18 shows another method for fixing the cleaning member 4 to the frame 3. In this example, the cleaning member 4 is an elastomer membrane having a cleaning surface 5, and a peripheral portion is fixed to a ring 23 that can be appropriately screwed to the frame 3.

  As shown in FIG. 19, this detachable connection of the cleaning member 4 to the handle 2 allows the user to enjoy the advantages of various cleaning members 4 having a plurality of different cleaning surfaces 5. be able to.

  Therefore, the user can select the cleaning member 4 according to the process to be performed.

  If appropriate, the handle 2 can be provided with one or more different cleaning members 4. Additionally, the handle 2 can be provided with one or more massage members 28 and / or can be suitably attached to the frame 3 and can also massage the contacting skin. A configured applicator member can be attached.

  FIG. 21 shows the possibility of permanently fixing the cleaning member 4 to the handle head 3 and the possibility of detachably fixing the head to the handle forming body 9. The head and the handle forming body 9 can be detachably fixed using, for example, a complementary shape of the uneven shape of the head 3 and the uneven shape of the body 9. This detachable fixing can be, for example, snapping or screwing.

  As shown in FIGS. 22 and 23, the cleaning member 4 can be formed as having fingers 36 on the surface opposite to the cleaning surface 5. This finger 36 is additionally arranged at a central position. Or in a modification, it arrange | positions in the position shifted | deviated from the center position.

  The user can deform the cleaning surface 5 by extending the cleaning member 4 by pressing the finger 36 in the longitudinal direction of the finger. Further, the user can deform the cleaning surface 5 by pressing the finger 36 in the lateral direction. For example, as shown in FIG. 23, at least one waveform can be formed in the cleaning surface 5.

  In a state where the cleaning member 4 is fixed to the frame 3, the user can directly press the surface 13 opposite to the cleaning surface 5 using the user's own finger. Alternatively, as shown in FIG. 24, the intermediate member 38 can be used to press the surface 13 opposite the cleaning surface 5. Here, the intermediate member 38 is formed integrally with the handle 2 and is connected to the handle 2 via, for example, a film hinge 39.

  The cleaning surface 5 can have various configurations. By way of example, cavities formed using the method described above with reference to FIGS. 1-6 can extend over regions 40-42 that are concentric with one another. All cavities in each region are, for example, assumed to exhibit substantially the same characteristics.

  In all the examples described above, the handle 2 can include a massage member 46 as shown in FIG. The massage member 46 can be attached, for example, as being rotatable about a rotation axis Z perpendicular to the longitudinal axis X of the body 9.

  Instead of being fixed to the handle 2, the cleaning surface 5 can be fixed to a lid 50 for closing the receptacle 51. For example, the receptacle contains a film-forming composition for application to the skin. For example, as shown in FIG. 27, the massage surface 5 is formed by the massage member 4 fixed to the top 52 of the lid 50.

  The user can remove and apply the composition by removing the lid 50 from the receptacle 51, thereby forming a mask.

  After completion of the treatment with the mask, the user uses the receptacle 51 as a handle member while keeping the lid 50 in a predetermined position (attached to the receptacle 51), so that the cleaning member 4 can be applied to the skin. By rubbing, the mask can be removed.

  The composition can be applied in various modes by using a hand, a finger, or an application member. The application member can be free from the receptacle containing the composition, or it can be free from the lid for closing the receptacle, or at least the application of the composition Sometimes it can be fixed to a receptacle or lid.

  If appropriate, the application member can be secured to the cleaning member 4 at least during application of the composition.

  FIG. 28 shows an example of a kit for adjusting and applying. In this case, the application member is fixed to the receptacle containing the composition and is in the form of a ball. In such an example, the cleaning member 4 is fixed with respect to the lid of the receptacle, for example.

  In the example of FIG. 29, the application member is fixed to a lid 50 for closing the receptacle. For example, the application member is disposed on the side opposite to the cleaning member 4. Thereby, when the lid 50 is disposed at a predetermined position, it can be engaged with the seat 60 of the receptacle.

  The seat 60 is provided with one or more openings 57. These openings 57 allow the composition to be supplied to the housing that receives the application member 55. The application member 55 is, for example, a foam, a sintered material, or any other member that can hold the composition on at least the surface.

  In the example of FIG. 30, the application member 55 is fixed with respect to the receptacle during application. The application member 55 is, for example, a foam, a sintered material, or any other permeable member that extends from the receptacle neck with at least the lid 50 removed.

  Supply to the application member 55 is, for example, an overpressure formed by capillary action, by the action of gravity when the receptacle is turned upside down, or by pressing the wall of the receptacle 51 Can be done.

  As shown in FIG. 31, the substance can also be supplied to the application member by a pump 61.

  Moreover, the pump can be used without using any applicable member. In that case, the user can take a sample directly at the pump outlet and apply the sample onto the area to be treated, for example, with a finger or hand.

  In the example of FIG. 32, the pump 61 is associated with the movable piston 63. Thereby, a composition can be extract | collected, without requiring operation which takes in air.

  In the example of FIG. 33, the receptacle 51 is a tube and the composition is supplied directly through the neck 64 of the tube, for example, without using any application member.

  In particular, in all examples in FIGS. 27 to 33, the cleaning member 4 can be various. For example, it can be attached to the lid 50 in a detachable manner. The cleaning member 4 can have other shapes. For example, at least two facets with different surface roughness can be provided.

  Although the present invention is not limited to the various examples described above and is not shown in the drawings, in the modification of the present invention, various feature points in these examples can be combined with each other.

  For example, the cleaning device can be provided with a vibrator.
