Description

Technical Field

[0001] The present invention relates to a jig for assisting the attachment of a film sheet to an attachment surface (skin, etc.). Background Art

[0002] In the past, it has been proposed to apply ink containing various colorants on a film and attach it to a human body to make spots, moles, scars (hereinafter also referred to as "discolored areas") on the skin less noticeable (for example, Patent Document 1). In the technology of Patent Document 1, the skin is photographed and the discolored areas are identified.

[0003] Furthermore, the same color as the surrounding color of the discolored area is printed on a film sheet, and the film sheet is attached to the skin to make the discolored area less noticeable.

[0004] Such a film sheet is usually circulated in the form of a laminated sheet stacked with a base paper, and is peeled off from the base paper by the user and attached to the skin. However, the film sheet is very thin, so it is difficult to attach the film sheet to the skin without wrinkles. Therefore, Patent Document 2 proposes a method of attaching the film sheet to the skin using a clamp. For example, the laminated sheet is placed on a clamp so that the film sheet faces the clamp, and water is sprayed on the base paper side. Then, the base paper is peeled off, and after the exposed film sheet is brought into close contact with the skin, the clamp is peeled off from the film sheet.

[0009] Problem that the invention aims to solve

[0010] However, since the film sheet is very thin, it is sometimes difficult to peel off the film sheet from the jig when transferring the film sheet from the jig to the attached surface. In addition, when attaching the film sheet to the attached surface using the jig, the pressure applied to the film sheet is sometimes uneven due to the unevenness of the attached surface, resulting in a portion of the film sheet not being in close contact with the attached surface.

[0011] An object of the present invention is to provide a jig capable of easily attaching a film sheet to an attachment surface.

[0012] Solutions to the problem

[0013] The present invention provides the following clamp.

[0014] The clamp is used to assist the film sheet to be attached to the surface to be attached, and the clamp includes:

[0015] a base having a first surface; and

[0016] A porous hydrophilic membrane is mounted on the first surface, and micropores are provided in the porous hydrophilic membrane at a predetermined opening ratio.

[0017] The opening ratio is 35% or more and 55% or less.

[0018] Effects of the Invention

[0019] According to the jig of the present invention, the film sheet can be easily attached to the attachment surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] (Implementation Method)

[0027] Hereinafter, Embodiment 1 of the present invention will be described in detail with reference to the drawings.

[0028] [Laminated Sheet]

[0029] First, use Figure 1 The structure of the laminated sheet 100 of the first embodiment is described. The laminated sheet 100 of the first embodiment has a structure in which a thin film sheet 11 for attaching to the skin and a support 12 are laminated. The laminated sheet can be in a roll or a single sheet. When the laminated sheet is in a roll, the required length is unwound for use. When the laminated sheet is in a roll, a cutting line (cut mark) or the like can be formed so that it can be cut to a desired length.

[0030] (Thin film)

[0031] The film sheet 11 may be a sheet (made on demand) made according to the discolored part of the skin of a specific individual by a known makeup assisting system or the like and used by a specific person. On the other hand, the film sheet 11 may be a sheet made according to the average skin color of a plurality of unspecified persons and used by a plurality of unspecified persons. The film sheet 11 may be used not only to add color to the skin, but also to make the discolored part inconspicuous or to decorate the discolored part by attaching it to the discolored part of the skin.

[0032] The film sheet 11 is a sheet with a thickness of 10 μm or less for being attached to the skin. The thickness of the film sheet 11 is preferably 10 nm to 10 μm, and more preferably 10 nm to 1000 nm. If the thickness of the film sheet 11 is within this range, there is no discomfort when it is attached to the attached surface such as the skin.

[0033] For example, the film sheet 11 can be made into a sheet consisting of a liquid-permeable film (not shown) and a coloring layer, a light scattering layer, etc. (not shown). If the film sheet 11 has a coloring layer, a light scattering layer, etc. in addition to the film, the color of the attached surface (such as skin, etc.) can be colored to any color by attaching the film sheet 11. More specifically, it is possible to add color to the skin, or make the discolored part of the skin look like a normal color. In addition, in the case where the film sheet 11 has a coloring layer, etc., it is preferably attached in a manner that the film in the film sheet 11 is in contact with the attached surface. In the case where the attached surface is the skin of the human body, a biocompatible film is attached in a manner that is in contact with the skin, thereby, it is not easy to cause irritation to the skin, etc. Here, in the case where the film sheet 11 has a coloring layer, the film sheet 11 is stacked on the support body 12 in a manner that the film faces the support body 12 described later.

[0034] Preferably, the film included in the film sheet 11 is a sheet-like member having biocompatibility and does not cause discomfort even when attached to human skin. In addition, preferably, the film is usually colorless, transparent or translucent.

[0035] The thickness of the thin film in the thin film sheet 11 is preferably 10 nm to 10 μm, more preferably 10 nm to 1000 nm. In addition, particularly when the thin film is hydrophobic, the thinness of the thin film is particularly preferably 10 nm to 800 nm.

[0036] The top view shape of the film is not particularly limited and can be appropriately selected according to the shape and purpose of the attachment portion of the film sheet 11. In addition, in order to make it suitable for the shape of the attachment portion of the film sheet 11, cuts can be formed on the periphery and / or in the surface of the film.

[0037] Here, the film may be a sheet formed by a spin coating method, a roll-to-roll method, an LB method (Langmuir-Blodgett method), or the like, or a fiber sheet formed by folding fibers produced by an electrospinning method or the like.

[0038] Examples of materials for the film include: polyesters represented by polyglycolic acid, polylactic acid, polycaprolactone, polyethylene succinate, polyethylene terephthalate, or copolymers thereof; polyethers represented by polyethylene glycol and polypropylene glycol; polyamides represented by nylon, polyglutamic acid, polyaspartic acid, or salts thereof; polysaccharides represented by pullulan, cellulose, starch, chitin, chitosan, alginic acid, hyaluronic acid, corn starch, or salts thereof; silicones represented by acrylic silicone and trimethylsiloxysilicate; acrylics represented by alkyl acrylate, acrylic silicone, acrylic amide, and copolymers thereof; polyvinyl alcohol; polyurethane; polycarbonate; polyanhydride; polyethylene; polypropylene; porous layer coated sheets, nanofiber sheets, etc. Among them, if the material of the film is polylactic acid, cellulose (eg, carboxymethyl cellulose, hydroxyethyl cellulose, etc.), starch, chitin, chitosan, alginic acid, corn starch, or polyurethane, the biocompatibility, availability, operability, etc. will be good.

[0039] On the other hand, the coloring layer disposed on the film contains a colorant and a binder. The coloring layer may further contain a film former, a dispersant, various additives, etc. The color of the coloring layer may generally be a color that matches the skin, but when the film sheet 11 is used as a cosmetic product such as blush, eye shadow, or body painting, it may be any color. In addition, the film sheet 11 may be the same color as a whole, or may have regions of different colors disposed on a portion thereof.

[0040] In addition, the coloring layer may be composed of one layer or two or more layers. In the case where the coloring layer is composed of multiple layers, the types of colorants contained in each layer may be the same or different. In addition, the amount of colorant contained in each layer may be the same or different. For example, a coloring layer of any color may be stacked on a skin-colored coloring layer.

[0041] Examples of colorants included in the coloring layer include: inorganic red pigments such as iron oxide, iron hydroxide, and iron titanate; inorganic brown pigments such as γ-iron oxide; inorganic yellow pigments such as iron oxide yellow and loess; inorganic black pigments such as iron oxide black and carbon black; inorganic purple pigments such as manganese violet and cobalt violet; inorganic green pigments such as chromium hydroxide, chromium oxide, cobalt oxide, and cobalt titanate; inorganic blue pigments such as navy blue (ferric ferrocyanide), ultramarine blue, glass, rock ultramarine, aluminum-cobalt oxide, aluminum-zinc-cobalt oxide, silicon-cobalt oxide, silicon-zinc-cobalt oxide, cobalt pigment, cyanine, cobalt blue, cobalt stannate, cobalt chrome blue, cobalt-aluminum-silicon oxide, and manganese blue; organic blue pigments or blue dyes such as indigo, phthalocyanine, indanthrene blue, and sulfonates thereof; substances obtained by laking various tar-based pigments, substances obtained by laking various natural pigments, and synthetic resin powders obtained by compounding these powders, etc.

[0042] On the other hand, the shape of the adhesive included in the coloring layer is not particularly limited, but is preferably in the form of particles, particularly preferably particles formed by (meth) acrylic resin (hereinafter, also referred to as "acrylic particles"). If the adhesive is formed by acrylic particles, the fixation of the above-mentioned colorant is easy to become good, and the durability of the coloring layer is easy to become good. The adhesive is further preferably particles formed by (meth) acrylic resin without skin irritation. Therefore, preferably, the above-mentioned acrylic particles are selected from the ingredients listed in the list of ingredient display names of cosmetics based on the Pharmaceutical Affairs Law of Japan, the ingredients that comply with the EU Cosmetics Directive (Cosmetics Directive 76 / 768 / EEC), the ingredients recorded in the International Cosmetic Ingredient Dictionary and Handbook (International Cosmetic Ingredient Dictionary and Handbook, January 1, 2002, the 9th edition) of the CTFA (Cosmetic, Toiletry & Fragrance Association, US), etc., and the above-mentioned acrylic particles are preferably particles of acrylic resins known to be used for cosmetic materials, etc.

[0043] When the amount of the colorant is set to 10 parts by mass, the amount of the binder contained in the colored layer is preferably 0.5 to 10 parts by mass, and more preferably 1.5 to 5.7 parts by mass. If the amount of the binder is within the above range relative to the amount of the colorant, the fixation of the colorant is improved. In addition, if the amount of the binder is within the above range, the amount of the colorant is relatively easy to become sufficient, and the colored layer can be made into a desired color.

[0044] The thickness of the coloring layer is appropriately selected according to the desired color concentration, but is preferably 10 nm to 15 μm, and more preferably 10 nm to 3 μm. If the thickness of the coloring layer is within this range, it is easy to obtain the desired color without producing a thick coating feeling. In addition, when multiple coloring layers are stacked, it is preferred that their total thickness is within this range. Such a coloring layer can be formed by applying ink containing a colorant and a binder on a film, for example, using inkjet printing, screen printing, offset printing, gravure printing, etc. The ink can be either oil-based or water-based. Among them, the inkjet method is preferred from the perspective of being easy to print on demand or being able to perform multiple coatings of cosmetic material inks.

[0045] On the other hand, in the light scattering layer, comprise reflective material and adhesive.In the light scattering layer, can further comprise film former, dispersant, various additives etc.The light scattering layer can be made up of one layer, also can be made up of two or more layers.When the light scattering layer is made up of multiple layers, the kind of reflective material included in each layer can be the same, also can be different.In addition, the amount of reflective material included in each layer can be the same, also can be different.

[0046] The reflective material included in the light scattering layer can be any particle that scatters or reflects ultraviolet light and visible light (e.g., light with a wavelength of 200 to 780 nm), and can be, for example, pearlescent agent, soft focus agent, glitter, etc. Pearlescent agent, soft focus agent and glitter are preferably non-skin irritating.

[0047] When the amount of the above-mentioned reflective material is set to 10 parts by mass, the amount of the adhesive contained in the light scattering layer is preferably 0.5 to 10 parts by mass, and more preferably 1.5 to 5.7 parts by mass. If the amount of the adhesive is within the above range relative to the amount of the reflective material, the fixation of the reflective material is improved. In addition, if the amount of the adhesive is within this range, the amount of the reflective material is relatively easy to become sufficient, and the light can be fully reflected or scattered by the light scattering layer.

[0048] The thickness of the light scattering layer is preferably 10 nm to 120 μm, more preferably 10 nm to 100 μm. When the thickness of the light scattering layer is within this range, light reflected on the surface of the skin is easily and sufficiently reflected by the light scattering layer.

[0049] In addition, in the film sheet 11, a glossy layer, a hygroscopic layer, etc. may be further laminated within the range that does not impair the purpose and effect of the present embodiment 1. If a hygroscopic layer is provided, the humidity on the surface side of the film sheet 11 is controlled, and the comfort is improved. The hygroscopic layer generally contains a hygroscopic agent, and examples of the hygroscopic agent include normal spherical silica, porous acrylic particles, nylon 6 (polyamide 6), etc.

[0050] (Support)

[0051] The support 12 is a plate-shaped member disposed on the other surface of the film sheet 11 , and has a function as a backing paper for protecting the film sheet 11 .

[0052] The shape of the support 12 is not particularly limited as long as it can cover one surface of the film sheet 11. The top view shape of the support 12 may be the same as the film sheet 11 or larger than the film sheet 11. For example, it may have a grip margin for gripping when peeling from the film sheet 11.

[0053] The thickness of the support 12 is preferably 50 to 2000 μm, more preferably 100 to 1500 μm. When the thickness of the support 12 is within this range, the support 12 can be easily deformed in any direction when peeling the support 12 from the film sheet 11 .

[0054] The support 12 is made of a hydrophilic material or a water-absorbent material capable of retaining water. In this specification, a hydrophilic material refers to a material having a contact angle of 90° or less, and a water-absorbent material refers to a material having a structure (such as pores) capable of retaining water.

[0055] Examples of materials for the support 12 include paper (cellulose), rayon, polyester, aramid, glass fiber, nylon, vinylon, polyolefins (e.g., polyethylene, low-density polyethylene, polypropylene, etc.), ethylene vinyl acetate resins, synthetic rubber, copolyamide resins, copolyester resins, porous membranes, nanofiber sheets, etc. Among them, paper (cellulose), rayon, and polyester are preferred from the viewpoint of easy peeling from the film sheet 11. In addition, the support 12 may or may not be light-transmissive. In addition, in order to distinguish between the surface on which the film sheet 11 is laminated and the surface on which the film sheet 11 is not laminated, one surface may be colored, or provided with characters or patterns.

[0056] In addition, preferably, the support 12 is flexible, and its elastic modulus is preferably 100 to 100,000 MPa, and more preferably 100 to 5,000 MPa. The elastic modulus is a value measured by one of a static test method, a lateral vibration method, and an ultrasonic method. The Japanese Industrial Standards (JIS standards) related to the elastic modulus measurement are JIS Z2280, JIS R1602, and JIS R1605, and the elastic modulus is a value measured according to one of them. If the elastic modulus of the support 12 is within the above range, it is not easy to break when peeled from the film sheet 11, and it can be deformed appropriately.

[0057] [Clamp]

[0058] Next, the structure of the clamp 200 of the first embodiment will be described using FIG. Figure 2A As shown, the jig 200 includes at least a base 21 and a porous hydrophilic membrane 22 attached to a first surface of the base 21 .

[0059] (Base)

[0060] The base 21 is a member for suppressing the bending of the film sheet 11 when the film sheet 11 is attached to the attached surface. Preferably, the base 21 has a structure with excellent flexibility so that when the film sheet 11 is pressed against the attached surface, it is elastically deformed in accordance with the concavoconvexity of the attached surface. Therefore, the Asker C hardness of the base 21 is preferably 4 degrees or more and 20 degrees or less.

[0061] The top view shape of the base 21 can be appropriately selected to match the shape of the attached surface, the shape of the laminated sheet 100 (especially the film sheet 11), etc., and has an area larger than the area of ​​the film sheet 11. The base 21 can be flat or have a curved surface (concave or convex). The details of the shape of the convex curved surface of the preferred first surface will be described later. In addition, the thickness of the base 21 is not particularly limited. From the perspective of operability, it is preferably about 0.1 to 15 mm, and more preferably about 0.1 to 8 mm.

[0062] The base 21 may or may not be transparent. However, it is preferably transparent from the viewpoint of being easy to identify the attachment position of the film sheet 11 when attaching the film sheet 11 to the attached surface. In addition, "having transparency" means, for example, that the transmittance of light at a wavelength of 550 mm is 40% or more.

[0063] The base 21 includes, for example, the following sheets: sheets containing rayon, polyester, aramid, glass fiber, nylon, vinylon, polyolefin (polyethylene, polypropylene, low-density polyethylene, etc.), ethylene vinyl acetate resin, synthetic rubber, copolyamide resin or copolyester resin, etc.; silicon (Si)-based sheets containing a hydrophilic agent; elastomer sheets containing a hydrophilic agent; rubber sheets made of aqueous gel, etc. These sheets may be sheets subjected to various hydrophilization treatments.

[0064] (Porous hydrophilic membrane)

[0065] The porous hydrophilic membrane 22 is composed of a film-shaped porous hydrophilic member. The contact angle of the porous hydrophilic membrane 22 with water is preferably 90° or less, more preferably 50° or less. If the contact angle of the porous hydrophilic membrane 22 with water is within this range, it is easy to form a layer of aqueous liquid uniformly on the surface of the porous hydrophilic membrane 22, and the thin film sheet is easy to be in close contact.

[0066] The porous hydrophilic membrane 22 is provided with micropores at a predetermined porosity. The porosity refers to the ratio of the open pores (micropores) per unit volume. In addition, Example 1 for determining the preferred range of the porosity will be described later.

[0067] If the porous hydrophilic film 22 is provided on the surface of the jig 200, the contact area with the film sheet 11 becomes smaller due to the micropores of the porous hydrophilic film 22, so the degree of close contact with the film sheet 11 is reduced. In addition, since the aqueous liquid enters the micropores of the porous hydrophilic film 22, the width of the layer of aqueous liquid between the jig 200 and the film sheet 11 increases. Therefore, it is easy to peel the film sheet 11 from the jig 200, and it is easy to transfer the film sheet 11 to the attached surface.

[0068] In the first embodiment, the top view shape of the porous hydrophilic film 22 is the same as the top view shape of the base 21, but the top view shape of the porous hydrophilic film 22 only needs to be larger than the top view shape of the film sheet 11, and it may be slightly smaller than the base 21. In addition, the thickness of the porous hydrophilic film 22 is 500 μm or less, and more preferably 100 μm or less.

[0069] The porous hydrophilic film 22 may be a film consisting of one layer (monolayer film) or a film consisting of two or more layers (multilayer film). For example, the porous hydrophilic film 22 may be a laminate of a substrate having desired elasticity and a hydrophilic film. Alternatively, they may be bonded together by an adhesive or the like. If the porous hydrophilic film 22 is a laminate of a hydrophilic film and an elastic substrate, even if the surface to which the film sheet is attached (the attached surface) is a curved surface, the porous hydrophilic film 22 can follow the shape, and the film sheet can be in close contact with the attached surface.

[0070] The hydrophilic surface of the porous hydrophilic film 22 (the surface facing the film sheet 11, the surface of the jig 200) may be smooth or have irregularities.

[0071] The porous hydrophilic film 22 may or may not be transparent, but from the viewpoint of easily recognizing the attachment position of the film sheet 11 when attaching the film sheet 11 to the attachment surface, it is preferred that both the porous hydrophilic film 22 and the base 21 are transparent.

[0072] Examples of the porous hydrophilic membrane 22 include the following membranes, for example, membranes comprising rayon, polyester, aromatic polyamide, glass fiber, nylon, vinylon, polyolefins (polyethylene, polyethylene terephthalate, polypropylene, low-density polyethylene, etc.), ethylene vinyl acetate resin, synthetic rubber, copolyamide resin or copolyester resin, etc.; silicon (Si)-based membranes containing a hydrophilic agent; elastic-based membranes containing a hydrophilic agent; rubber-based membranes made of aqueous gel, etc.

[0073] The porous hydrophilic film 22 is bonded and fixed to the first surface of the base 21 by an adhesive (not shown) or the like. The adhesive bonding the base 21 and the porous hydrophilic film 22 is preferably a hydrophobic adhesive.

[0074] (Base)

[0075] like Figure 2B As shown, the jig 200 may include a base 23 in addition to the base 21 and the porous hydrophilic membrane 22 .

[0076] The base 23 is made of a soft porous member such as a sponge structure. In addition, the base 23 is more preferably a closed cell structure (non-water-absorbing structure).

[0077] A through hole is provided in the center of the base 23 so as to maintain the flexibility of the base 21 when the base 23 is fixed to the base 21. That is, the outer shape of the base 23 is frame-shaped.

[0078] In the first embodiment, the top view shape of the base 23 is almost the same as the base 21 at the periphery. In addition, the thickness of the base 23 is not particularly limited, but is preferably about 0.1 to 15 mm, and more preferably about 0.1 to 8 mm, from the perspective of operability. In addition, in order to uniformly apply pressure to the attached surface, the Ascar C hardness of the base 23 is preferably 5 degrees or more, and more preferably 10 degrees or more.

[0079] Examples of the material of the base 23 include acrylic resin, PET (polyethylene terephthalate), PC (polycarbonate), rigid polyvinyl chloride (vinyl chloride), and the like.

[0080] The base 23 is bonded and fixed to the bottom surface (the surface opposite to the first surface) of the base 21 by an adhesive (not shown) or the like. The adhesive bonding the base 21 and the base 23 is preferably a hydrophobic adhesive.

[0081] [How to use the laminated sheet]

[0082] Next, use Figure 3A to Figure 3C A method of using the laminate sheet 100 according to the first embodiment will be described. Figure 3A to Figure 3C yes Figure 1 , Figure 2AHowever, the method of using the laminated sheet 100 of the first embodiment is not limited to the following method.

[0083] First, if Figure 3A As shown, the user places the laminated sheet 100 on the jig 200 so that the porous hydrophilic film 22 of the jig 200 faces the film sheet 11. That is, the porous hydrophilic film 22 functions as a temporary attachment portion of the film sheet 11.

[0084] Then, the user uses a sprayer or the like to spray a highly biologically safe aqueous liquid such as water, lotion, or moisturizer from the side of the support 12 of the laminated sheet 100 to the entire body. As a result, the hydrophilic or water-absorbent support 12 contains the aqueous liquid, and a layer of the aqueous liquid is formed between the support 12 of the laminated sheet 100 and the film sheet 11 (not shown). In addition, at this time, the laminated adsorption between the film sheet 11 that has been soaked with the aqueous liquid and the fixture 200 is also generated.

[0085] Afterwards, if Figure 3B As shown, the user lifts up the support 12 and peels the support 12 off the film sheet 11 .

[0086] Then, if Figure 3C As shown, the user holds the clamp 200 and brings the film sheet 11 placed on the clamp 200 into close contact with the attached surface (not shown). Then, the user uses the clamp 200 to press the film sheet 11 toward the attached surface, thereby peeling the film sheet 11 from the clamp 200 and transferring it to the attached surface. At this time, the user elastically deforms the base 21 in accordance with the concave and convex of the attached surface, thereby evenly applying pressure to the attached surface, and evenly bringing the film sheet 11 into close contact with the attached surface.

[0087] Furthermore, when the film sheet 11 is transferred to the attached surface, if a water layer exists between the film sheet 11 and the porous hydrophilic film 22 of the jig 200, the film sheet 11 is easily peeled off from the jig 200. Therefore, as needed, water may be sprayed onto the attached surface or the film sheet 11 using a sprayer or the like to facilitate peeling of the film sheet 11 from the jig 200.

[0088] [Positioning method]

[0089] As described above, when the base 21 and the porous hydrophilic film 22 of the jig 200 are both transparent, the user can easily recognize the attachment position of the film sheet 11 when attaching the film sheet 11 to the attached surface. Next, a specific example of the method of aligning the film sheet 11 when using the transparent jig 200 is described.

[0090] (Example 1)

[0091] Example 1 is a method of aligning the film sheet 11 and the attached surface while observing through the jig 200. For example, the user aligns the position of the concealer print portion of the film sheet 11 with the position of the skin spot while observing through the jig 200 and presses the jig 200 to the center of the cheekbone.

[0092] (Example 2)

[0093] Example 2 is a method of adding a mark (dot, line, frame, etc.) for alignment in advance to the jig 200. For example, a mark is added to the base 21 or the porous hydrophilic film 22 by printing or the like, and the guide is a guide for indicating the portion where the film sheet 11 should be placed. Alternatively, a mark is added to the base 21 or the porous hydrophilic film 22 by printing or the like, indicating the portion of the jig 200 to be pressed against a predetermined portion of the attached surface (face) such as the center of the cheekbone or the side of the nose wing.

[0094] (Example 3)

[0095] Example 3 is a method of using microscopic holes provided on the porous hydrophilic film 22 of the jig 200 as a marker. The location of the microscopic holes defines the portion of the jig 200 to be pressed against a predetermined portion of the attached surface (face) such as the center of the cheekbone or the side of the nose.

[0096] (Example 4)

[0097] Example 4 is a method of using the inner circumference of the base 23 of the clamp 200 as a mark. The positional relationship with the inner circumference of the base 23 defines the portion of the clamp 200 to be pressed against a predetermined portion of the attached surface (face), such as the center of the cheekbone or the side of the nose.

[0098] [other]

[0099] The clamp 200 of the present invention may also be housed in the cosmetic assembly 300 . Figure 4 It is a perspective view of the cosmetic set 300 including the clip 200 of the first embodiment.

[0100] In the cosmetic assembly 300, the laminated sheet 100 and the jig 200 are held inside the housing 31. At this time, the laminated sheet 100 is arranged so that the support 12 faces the inner bottom surface of the housing 31. And the jig 200 is placed on the film sheet 11 of the laminated sheet 100 so that the porous hydrophilic film 22 faces the film sheet 11.

[0101] [Example]

[0102] The preferred range of the opening ratio of the micropores of the porous hydrophilic membrane 22 of the present invention will be described in detail below with reference to examples. The scope of the present invention is not to be construed as limited by the examples.

[0103] [Example 1]

[0148] Table 1

[0149]

[0150] [result]

[0151] As shown in Table 1 above, in Example 1 in which micropores are provided at a predetermined opening ratio, both the single-layer film and the multilayer film obtained good evaluation values, compared with the comparative example without micropores. In particular, when the opening ratio A is within the range of 35% ≤ A ≤ 55%, the evaluation values ​​of all items are "A".

[0152] [Effect]

[0153] As described above, according to Example 1 of the present embodiment 1, the porous hydrophilic film 22 of the jig 200 is provided with micropores at a predetermined opening ratio. As a result, when water is sprayed onto the laminated sheet 100, the water easily spreads from the central portion to the end portion of the laminated sheet 100, and the water layer easily spreads between the thin film sheet 11 and the porous hydrophilic film 22. Therefore, the water uniformly spreads over the entire laminated sheet 100. Thus, the thin film sheet 11 can be easily transferred from the jig 200 to the attached surface.

[0154] In addition, since the base 21 of the jig 200 is flexible, it is possible to apply pressure uniformly to the attached surface, and the film sheet 11 can be brought into uniform and close contact with the attached surface. Therefore, the film sheet 11 can be easily attached to the attached surface.

[0155] [Example 2]

[0156] As Example 2, a jig 200 is prepared in which the first surface of the base 21 is a convex curved surface as a whole and the radius of curvature R is the value shown in Table 2 (R = 10, 30, 40, 50, 70, 90, 150, 160 (unit: mm)). Preferably, the base 21 has a rigidity to such an extent that it will not be significantly twisted due to the reaction force from the attached surface when the film sheet 11 is pressed against the attached surface. Therefore, the thickness of the base 21 is preferably within the range of 6 mm or more and 50 mm or less.

[0157] [Comparative Example 2-1]

[0158] As Comparative Example 2-1, a jig 200 was prepared in which the first surface of the base 21 was flat and a silicone puff was bonded to the base 21 instead of the hydrophilic film 22. Also, as Comparative Example 2-2, a jig 200 was prepared in which the first surface of the base 21 was flat and a hydrophilic film 22 was bonded to the base 21.

[0159] In each of the examples and comparative examples, the following steps were performed a plurality of times.

[0160] (1) The laminated sheet 100 is placed on the hydrophilic film 22 (silicone puff) of the jig 200 with the support 12 on top, and water is sprayed toward the support 12 side.

[0161] (2) Thereafter, the support 12 is peeled off from the film sheet 11 , and the film sheet 11 is attached to the attachment surface using the jig 200 .

[0162] [evaluate]

[0163] For each of the above-mentioned Examples 2 and Comparative Examples 2, the following items were evaluated. The results are shown in Table 2. In addition, as the evaluation value of each item, "A" represents a level with no problem at all. In addition, "B" represents a level that is worse than "A" but has no practical problem. In addition, "C" represents a level with practical problems.

[0199] Table 2

[0200]

[0201] [result]

[0202] As shown in Table 2, in Example 2 in which the first surface is a convex curved surface, good evaluation values ​​were obtained compared to the comparative example in which the first surface is a flat surface. In particular, when the radius of curvature R is in the range of 30≤R≤150, the evaluation values ​​of items 1 to 3 when attached to the skin are "A". Furthermore, when the radius of curvature R is in the range of 40≤R≤90, the evaluation values ​​of all items are "A".

[0203] [Effect]

[0204] As described above, according to Example 2 of the present embodiment 1, the first surface of the clamp 200 may also have a convex curved surface. Thus, by rolling the clamp 200 in parallel with the attached surface using the convex curved surface of the surface of the clamp 200, the user can apply pressure evenly to the attached surface, and the film sheet 11 can be evenly and closely contacted with the attached surface. Thus, the film sheet 11 can be easily attached to the attached surface.

[0205] In addition, since the first surface of the jig 200 has a convex curved surface, when water is sprayed onto the laminated sheet 100, the water easily spreads from the center portion to the end portion of the laminated sheet 100, and the water layer easily spreads between the film sheet 11 and the hydrophilic film 22. Thus, the water uniformly spreads over the entire laminated sheet 100. Thus, the film sheet 11 can be easily transferred from the jig 200 to the attached surface.

[0206] (Implementation Method 2)

[0207] In the second embodiment, a structure in which the base 21 is not used, as opposed to the jig 200 of the first embodiment, will be described.

[0208] [Laminated Sheet]

[0209] The structure of the laminated sheet of the second embodiment is similar to that of the first embodiment ( Figure 1 ) is the same as the stacked sheet 100 described in the previous section, and therefore the description thereof is omitted.

[0210] Next, the film holder 400 of the second embodiment (see Figure 5A to Figure 5C ) is described. The membrane fixture 400 is similar to the one in Embodiment 1 ( Figure 2A ) does not have a base 21, but only has a porous hydrophilic membrane 22.

[0211] (Porous hydrophilic membrane)

[0212] Preferably, the porous hydrophilic film 22 of Embodiment 2 has a structure with excellent flexibility, and when the film sheet 11 is pressed against the attached surface, it is elastically deformed in accordance with the concavoconvexity of the attached surface. Therefore, the Ascar C hardness of the porous hydrophilic film 22 is preferably 4 degrees or more and 20 degrees or less.

[0213] The porous hydrophilic film 22 is made transparent in order to easily identify the attachment position of the film sheet 11 when attaching the film sheet 11 to the attachment surface. Here, "transparent" means, for example, that the transmittance of light at a wavelength of 550 mm is 40% or more.

[0214] The other aspects of the porous hydrophilic membrane 22 of the second embodiment are the same as those of the first embodiment, and thus detailed descriptions thereof are omitted.

[0215] [How to use the laminated sheet]

[0216] Next, use Figure 5A to Figure 5C The method of using the laminated sheet 100 according to the second embodiment will be described. However, the method of using the laminated sheet 100 according to the second embodiment is not limited to the following method.

[0217] First, if Figure 5A As shown, the user places the laminated sheet 100 on the membrane holder 400 so that the porous hydrophilic film 22 of the membrane holder 400 faces the film sheet 11. That is, the porous hydrophilic film 22 functions as a temporary attachment portion of the film sheet 11.

[0218] Then, the user uses a sprayer or the like to spray a highly biologically safe aqueous liquid such as water, lotion, or moisturizer from the side of the support 12 of the laminated sheet 100 to the entire body. As a result, the hydrophilic or water-absorbent support 12 contains the aqueous liquid, and a layer of the aqueous liquid is formed between the support 12 of the laminated sheet 100 and the film sheet 11 (not shown). In addition, at this time, the film sheet 11 that has been permeated with the aqueous liquid and the film fixture 400 are also laminated and adsorbed.

[0219] Afterwards, if Figure 5B As shown, the user lifts up the support 12 and peels the support 12 off the film sheet 11 .

[0220] Then, if Figure 5C As shown, the user holds the film clamp 400 and brings the film sheet 11 placed on the film clamp 400 into close contact with the attached surface (not shown). Then, the user uses the film clamp 400 to press the film sheet 11 toward the attached surface, thereby peeling the film sheet 11 from the film clamp 400 and transferring it to the attached surface. At this time, the user elastically deforms the base 21 in accordance with the concave and convex of the attached surface, thereby evenly applying pressure to the attached surface, and evenly bringing the film sheet 11 into close contact with the attached surface.

[0221] Furthermore, when the film sheet 11 is transferred to the attached surface, if a water layer exists between the film sheet 11 and the porous hydrophilic film 22 of the film holder 400, the film sheet 11 is easily peeled off from the film holder 400. Therefore, as needed, water may be sprayed onto the attached surface or the film sheet 11 using a sprayer or the like to facilitate peeling of the film sheet 11 from the film holder 400.

[0222] [Positioning method]

[0223] As described above, when the porous hydrophilic film 22 is transparent, the user can easily identify the attachment position of the film sheet 11 when attaching the film sheet 11 to the attached surface. In the second embodiment, the film sheet 11 can be aligned using the transparent film fixture 400 using the alignment method of Examples 1 to 3 illustrated in the first embodiment.

[0224] [other]

[0225] In implementation mode 1 ( Figure 4 ) Similarly to the clamp 200 described in the above, the film clamp 400 of the present invention can also be housed in the cosmetic component 300.

[0226] [Example]

[0227] The preferred range of the opening ratio of the micropores of the porous hydrophilic membrane 22 of the present invention will be described in detail below with reference to Examples. It should be noted that the scope of the present invention is not to be construed as limited by the Examples.

[0228] [Example 3]

[0229] As Example 3, a membrane holder 400 was prepared in which the porous hydrophilic membrane 22 was a single-layer membrane or a multi-layer membrane and the micropore opening ratio A was the value (%) shown in Table 1. The opening ratio A was calculated from the micropore diameter D and the micropore pitch P by the following formula.

[0230] A=78.5×D 2 / P 2

[0231] [Comparative Example 3]

[0232] As Comparative Example 3, a membrane holder 400 using a hydrophilic membrane (without micropores) instead of the porous hydrophilic membrane 22 was prepared.

[0233] In each of the examples and comparative examples, the following steps were performed a plurality of times.

[0234] (1) The laminated sheet 100 is placed on the porous hydrophilic membrane 22 (silicone puff, hydrophilic membrane) of the membrane holder 400 so that the support 12 is on top, and water is sprayed toward the support 12 side.

[0235] (2) Thereafter, the support 12 is peeled off from the film sheet 11 , and the film sheet 11 is attached to the attachment surface using the film jig 400 .

[0272] C: The water layer does not extend between the thin film sheet 11 and the porous hydrophilic membrane 22 .

[0273] Table 3

[0274]

[0275] [result]

[0276] As shown in Table 3, compared with Comparative Example 3 without micropores, Example 3 having micropores at a predetermined opening ratio obtained good evaluation values ​​for both the single-layer film and the multilayer film. In particular, when the opening ratio A was within the range of 35% ≤ A ≤ 55%, the evaluation values ​​of all items were "A".

[0277] [Effect]

[0278] As described above, according to the second embodiment, the porous hydrophilic film 22 of the film fixture 400 is provided with micropores at a predetermined opening ratio. Thus, when water is sprayed onto the laminated sheet 100, the water easily spreads from the central portion to the end portion of the laminated sheet 100, and the water layer easily spreads between the thin film sheet 11 and the porous hydrophilic film 22. Therefore, the water uniformly spreads over the entire laminated sheet 100. Thus, the thin film sheet 11 can be easily transferred from the film fixture 400 to the attached surface.

[0279] In addition, since the porous hydrophilic membrane 22 of the membrane holder 400 is porous, it is softer than a hydrophilic membrane without micropores, so that even if the membrane alone does not have the base 21, it is possible to uniformly apply pressure to the attached surface, and the film sheet 11 can be uniformly and closely contacted with the attached surface. Therefore, the film sheet 11 can be easily attached to the attached surface.

[0280] In addition, the material of the membrane holder 400 may be any flexible member and is not limited to a membrane, and may be a plate-like member whose surface is processed to be porous and hydrophilic.
