[0038] (Insights, etc., which are the basis of this disclosure)

[0039] At the time when the inventors of the present invention thought of the present disclosure, the importance of improving the tactile sensation of the skin-touching portion of the care device that is in contact with or worn on the skin had not been fully recognized. However, the inventors of the present invention found that improving the tactile sensation of the skin-touching portion of the care device is effective for the relaxation and healing effects of the care device, and conducted in-depth research on improving the tactile sensation of the skin-touching portion of the care device.

[0040] It can be considered that the sense of touch when a person touches an object is affected by the physical property value of the object. The inventors of the present invention have newly discovered that when a person touches an object, the sense of touch felt by the person is related to the hardness of the object and the static friction coefficient of the object against the skin, and the sense of touch can be controlled by the hardness and static friction coefficient of the object. When the hardness of an object is low, a person will feel soft. After in-depth research, the inventors of the present invention found that when the Asker C hardness of an object is below 30 degrees, the comfort of the sense of touch of the skin is improved. In addition, as mentioned above, with respect to the static friction coefficient of an object, the static friction coefficient against human skin is related to the sense of touch. Therefore, in order to express the sense of touch of the skin against an object, the friction coefficient against the skin of a person being rubbed is required. However, it is difficult to evaluate the friction coefficient against the skin of a person having specific surface characteristics and softness. The inventors of the present invention have found that the static friction coefficient of an artificial skin whose physical properties are close to those of human skin can be used as an indicator of the sense of touch of human skin.

[0041] The inventors of the present invention have conducted intensive studies and found that when the static friction coefficient of an object with respect to artificial skin, which is a material close to human skin, is 3 or less, the comfort of the touch of the skin is improved.

[0042] Artificial skin is a product that mimics human skin and has a touch and softness that is close to human skin, and is used for suture training in the medical field or evaluation of cosmetics. The inventors of the present invention focused on the specific surface characteristics and softness of human skin, clarified the physical properties that serve as indicators of surface characteristics and softness, and found that the static friction coefficient against human skin can be evaluated by using artificial skin whose physical properties are close to those of human skin.

[0043] Therefore, the present disclosure provides a care device that contacts or is worn on the skin, the care device having a skin-wearing component including an elastic body, the skin-wearing component having an Asker C hardness of 30 degrees or less, and having a static friction coefficient of 3 degrees or less. In addition, in the present disclosure, the Asker C hardness and the static friction coefficient of the skin-wearing component are the Asker C hardness and the static friction coefficient of the surface of the skin-wearing component that contacts the skin when the care device is contacted with the skin or worn on the skin. Here, the above-mentioned static friction coefficient is the static friction coefficient of an artificial skin sheet that satisfies the following characteristics (A) and (B).

[0044] (A) The compressive stress of the artificial skin sheet when pressed into the thickness direction to a depth of 2 mm is 0.01 MPa or more and 0.05 MPa or less.

[0045] (B) The arithmetic mean roughness Ra of the surface of the artificial skin sheet is 5 μm to 10 μm. That is, the arithmetic mean roughness Ra of the surface of the artificial skin sheet is 5 μm or more and 10 μm or less.

[0046] In the present disclosure, the Asker C hardness of the skin-wearing member is a value at room temperature (eg, 25° C.). The compressive stress of the artificial skin sheet used when pressed to a depth of 2 mm in the thickness direction is also a value at room temperature (eg, 25° C.).

[0047] The following is a detailed description of the embodiments with reference to the accompanying drawings. However, unnecessary detailed descriptions are sometimes omitted. For example, detailed descriptions of well-known matters or repeated descriptions of substantially the same structures are sometimes omitted. This is to avoid the following description from becoming unnecessarily lengthy and to make it easy for those skilled in the art to understand.

[0048] In addition, the drawings and the following descriptions are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims through these drawings and descriptions.

[0049] (Implementation Method 1)

[0050] Next, use Figures 1 to 8 The implementation method will be described.

[0051] [1-1. Structure]

[0052] The care device in Embodiment 1 is a care device that is in contact with the skin or worn on the skin. The care device in this embodiment has a skin-wearing component that includes an elastomer. The Asker C hardness of the skin-wearing component is 30 or less, and the skin-wearing component has a static friction coefficient of 3 or less. In addition, in this embodiment, the Asker C hardness and static friction coefficient of the skin-wearing component are the Asker C hardness and static friction coefficient of the surface of the skin-wearing component that contacts the skin when the care device is in contact with the skin or worn on the skin. Here, the static friction coefficient is the static friction coefficient of an artificial skin sheet that satisfies the following characteristics (A) and (B).

[0053] (A) The compressive stress of the artificial skin sheet when pressed into the thickness direction to a depth of 2 mm is 0.01 MPa or more and 0.05 MPa or less.

[0054] (B) The surface of the artificial skin sheet has an arithmetic mean roughness Ra of 5 μm to 10 μm.

[0055] As an artificial skin sheet having the above-mentioned characteristics, for example, "BIOSKIN BPS-01L" manufactured by Regina Corporation can be used.

[0056] The care device in this embodiment includes the skin wearing member having the above-mentioned structure, and thus can improve the comfort when the care device comes into contact with the skin and is worn on the skin.

[0057] In the present embodiment, the above-mentioned properties (A) and (B) of the artificial skin sheet used when determining the static friction coefficient of the skin wearing member can be obtained by the method described below.

[0058] Human skin has a multilayer structure consisting of epidermis, dermis, subcutaneous tissue, etc., and is a laminate of layers with different elastic moduli. The thickness of the skin is about 2 mm on average. The softness of the laminate can be evaluated by the stress and strain of the indentation force on the surface of the laminate. Thus, the softness of human skin is evaluated based on the strain and stress when the indentation force is applied to the skin surface. In the present disclosure, the compressive stress obtained by the rebound force when a 2 mm deep indentation force is applied to the surface of the artificial skin sheet in the thickness direction is used as an indicator of the softness of human skin.

[0059] The compressive stress when pressed into a depth of 2 mm is obtained by measuring the load when a cylindrical probe with a diameter of 5 mm is pressed into the surface of the sample (i.e., human skin) at a speed of 10 mm / min at room temperature using, for example, a dynamometer system ZTA-50N or MX2-500N-FA (manufactured by IMADA). The compressive stress when the human skin is pressed into a depth of 2 mm is measured at five points on the skin of the palm and upper arm.

[0060] The compressive stress when human skin is pressed into 2mm is in the range of 0.01MPa or more and 0.05MPa or less. The same measurement was also performed on "BIOSKIN BPS-01L" manufactured by Regina, one of the artificial skins. The result was that the compressive stress when pressed into 2mm was 0.026MPa. It can be confirmed that the physical property values ​​of "BIOSKIN BPS-01L" manufactured by Regina are within the range of the compressive stress when human skin is pressed into 2mm, which is close to human skin.

[0061] The surface of human skin has an uneven shape based on wrinkles and pores. The surface characteristics based on the uneven shape can be expressed by surface roughness. Regarding the surface roughness of human skin, Non-Patent Literature 1 shows that the arithmetic mean roughness Ra of the cheek skin of women in their 20s to 50s is in the range of 5μm to 16μm. The surface roughness of "BIOSKIN BPS-01L" manufactured by Regina, one of the artificial skins, was evaluated. As a result, the arithmetic mean roughness Ra was 8.0μm. It can be confirmed that the arithmetic mean roughness Ra of "BIOSKIN BPS-01L" manufactured by Regina is within the range of the arithmetic mean roughness of human skin and is close to human skin. In addition, the arithmetic mean roughness Ra of "BIOSKIN BPS-01L" manufactured by Regina was measured using a shape analysis laser microscope manufactured by KEYENCE, and the measurement was performed at three points and the average value was calculated.

[0062] In this embodiment, in order to determine the static friction coefficient of the skin-worn component, a commercially available artificial skin having properties close to those of human skin, a compressive stress of 0.01 MPa or more and 0.05 MPa or less when pressed into a depth of 2 mm, and an arithmetic mean roughness Ra of 5 μm to 10 μm is used. In this embodiment, as such an artificial skin, for example, "BIOSKIN BPS-01L" manufactured by Regina Corporation is used.

[0063] The care device in this embodiment includes at least a skin-wearing member having an Asker C hardness of 30 or less and a static friction coefficient of 3 or less for the artificial skin sheet having the above-mentioned characteristics (A) and (B), so that the care device can be used comfortably when it is in contact with the skin or worn on the skin. By feeling comfortable, the care device can be relaxed, healed, and easy to fall asleep.

[0064] The care device has at least a skin-wearing member having an Asker C hardness of 30 or less and a static friction coefficient of 3 or less with respect to the artificial skin sheet having the above-mentioned properties (A) and (B). The skin-wearing member has a skin contact surface.

[0065] Figure 1 This is a cross-sectional view showing an example of the care equipment in the first embodiment. Figure 1 The care device 100 shown has a structure in which the skin-wearing member 1 is held on the frame 3. Figure 1 As shown in FIG. 1 , the skin-wearing member 1 may be in the form of a sheet, for example. In this case, one surface of the skin-wearing member 1 is the portion in contact with the skin. Hereinafter, the portion in contact with the skin of the skin-wearing member 1 is referred to as the skin contact surface 2. Figure 1As shown, the skin wearing member 1 may be held by the frame 3, or may have a structure in which at least a part of the support portion 4 is coupled to the frame 3. The support portion 4 may be an end portion of the skin wearing member 1, for example.

[0066] The shape of the skin wearing member 1 of the care device 100 in this embodiment is appropriately determined according to the body part of the person who contacts or wears the care device, and is therefore not particularly limited. Figure 1 Like the skin wearing member 1 shown in the figure, in the care device 100 in this embodiment, the skin wearing member 1 may be in a sheet shape, for example.

[0067] The tensile strength of the skin-mounted component 1 may be greater than 1 N / mm 2 By making the tensile strength of the skin-mounted component 1 greater than 1 N / mm 2 , so that it will not be damaged even when worn on the skin in a tension-applied manner, and can be used stably even after repeated use.

[0068] The skin wearing member 1 includes at least an elastomer, and may be formed of, for example, a polymer material including an elastomer. The skin wearing member 1 may also be formed of only an elastomer. For example, the skin wearing member 1 may be a single-layer sheet made of an elastomer.

[0069] In the present embodiment, the skin wearing member 1 may have a multilayer structure including a plurality of layers. Figure 2 2 is a cross-sectional view showing an example of a skin-worn component having a multilayer structure. Figure 2 As shown, the skin wearing component 1 may include, for example, a substrate 11 including an elastomer, and a film 12 having a thickness of 100 μm or less and arranged at least in an area 11a facing the skin on the surface of the substrate 11. The skin wearing component 1 may also include a film 13 arranged in an area 11b not facing the skin on the surface of the substrate 11. The film 13 may have a thickness of 100 μm or less. In the case where the substrate 11 is, for example, a sheet-like object, the area 11a facing the skin on the surface of the substrate 11 is equivalent to one main surface of the substrate 11 (hereinafter, sometimes referred to as the "first main surface"), and the area 11b on the surface of the substrate 11 not facing the skin is equivalent to the other main surface of the substrate 11, that is, the second main surface facing the first main surface. Here, the main surface refers to the surface with the largest area. The second main surface is the surface on the opposite side of the first main surface.

[0070] As described above, the skin wearing component 1 includes the film 12 disposed at least in the area 11a facing the skin on the surface of the base material 11, thereby making it easy to reduce the static friction coefficient of the surface of the skin wearing component 1 in contact with the skin. In addition, by providing the film 12, the strength of the skin wearing component 1 can be improved. As a result, the skin wearing component 1 is not easily damaged, and the friction resistance is also enhanced, so that the long-term durability of the skin wearing component 1 is improved. By also providing the film 13, the strength of the skin wearing component 1 can be further improved, so that the long-term durability of the skin wearing component 1 can be further improved.

[0071] By making the thickness of the film 12 less than 100 μm, the comfort of the skin wearing component 1 in contact with the skin can be obtained. If the thickness of the film 12 is less than 50 μm, a higher comfort can be felt. If it is less than 30 μm, a higher comfort can be obtained with a natural touch. There is no particular limitation on the thickness of the film 13, but it is expected that it is not too thick so that the skin wearing component 1 has a softness that matches the surface shape of the skin when the care device is worn. The thickness of the film 13 can be, for example, less than 100 μm.

[0072] The film 12 can be bonded to the surface of the substrate 11 by utilizing the adhesive force of the elastomer contained in the substrate 11, the intermolecular force between the elastomer and the film 12, or the van der Waals force between the elastomer and the film 12. Alternatively, the substrate 11 and the film 12 can be fused by heat fusion, or an adhesive layer can be provided on the film 12 and the film 12 can be bonded to the substrate 11 by the adhesive layer. The adhesive layer can use an adhesive, a moisture-curing adhesive such as a cyanoacrylate or silicone rubber adhesive, a solvent-evaporating adhesive, a thermosetting adhesive, a two-liquid mixed adhesive, a hot melt adhesive, etc. The description of the bonding of the film 13 to the surface of the substrate 11 is the same as that of the film 12.

[0073] Examples of the material of the film 12 and the film 13 include thermoplastic elastomers such as polystyrene, polyurethane, polyester, polyolefin, acrylic resin, and polyvinyl chloride.

[0074] Regarding the adhesion between the substrate 11 and the film 12, it is desirable that the adhesion is 0.3 N or more in a peel test conducted at a width of 15 mm. In the present embodiment, the peel test between the substrate 11 and the film 12 is conducted according to the test method of ASTM F88. By setting the adhesion between the substrate 11 and the film 12 to 0.3 N or more, the following effect can be obtained: the film 12 can be prevented from peeling off from the substrate 11 during use, thereby preventing the occurrence of poor appearance such as bubbles entering the interface.

[0075] The entire surface of the substrate 11 may be covered with a film. That is, the substrate 11 may be sealed with a film. Figure 3A and Figure 3B: is a cross-sectional view showing a structure in which the base material 11 is sealed by a film in the skin-wearing component 1. Such a sealed structure can be obtained, for example, by bonding the film 12 and the film 13 to each other at the side portion of the base material 11. The care device 100 that comes into contact with the skin or is worn on the skin is used in a manner that comes into contact with the skin, and therefore is required to have high water resistance and oil resistance against moisture such as sweat on the skin, oil components such as sebum, and cosmetic components applied to the skin. By sealing the entire base material 11 including the elastomer with a film, the film is not easily peeled off from the end of the skin-wearing component 1 even when immersed in water or oil, or when a strong force is applied. As Figure 3A As shown, the film 12 and the film 13 can be directly bonded to each other. Such bonding can be, for example, heat welding. Figure 3B As shown, the substrate 11 and the film 12 and the film 13 may be bonded via the adhesive layer 14, and the film 12 and the film 13 may be bonded to each other at the side portion of the substrate 11 via the adhesive layer 14. The adhesive layer includes adhesives, moisture-curing adhesives such as cyanoacrylate or silicone rubber, solvent-evaporating adhesives, thermosetting adhesives, two-liquid mixed adhesives, hot-melt adhesives, and the like.

[0076] In the present embodiment, the skin-wearing component may include, for example: a substrate including an elastomer; and a coating, which is arranged at least in the area facing the skin in the surface of the substrate, and the coating includes a powder. By applying a coating including a powder, a more refreshing touch can be felt, thereby achieving a high degree of comfort. As materials for the powder, for example, inorganic powders such as zinc oxide, titanium oxide, talc, kaolin, mica, silica, titanium dioxide, and iron oxide, and organic powders such as silicone resins, polyethylene, polypropylene, polyolefins, and acrylic acid can be cited. The coating including the powder can be formed by directly attaching the powder to the above-mentioned substrate, or by applying a coating obtained by mixing the powder into a resin to the above-mentioned substrate.

[0077] The vertical indentation depth when a 1N load is applied to the skin contact surface 2 of the skin wearing component 1 in a direction perpendicular to the surface using a cylindrical indentation jig having a diameter of 5 mm is preferably 1 mm or more. The indentation depth is the indentation depth measured for the skin wearing component 1 in a state where the skin wearing component 1 is set on the care device 100. For example, when the skin wearing component 1 is Figure 1When the skin-wearing member 1 is set in a state held on the frame 3 as shown, the above-mentioned pressing depth is a value measured for the skin-wearing member 1 in a state held on the frame 3. When the care device 100 is brought into contact with the skin or worn on the skin, a load is applied to the skin-wearing member 1 to deform the skin contact surface 2 in accordance with the shape of the skin so that it is easy to fit the skin. By making the skin contact surface 2 fit the skin, the person can strongly feel the touch of the skin contact surface 2 of the skin-wearing member 1. By making the pressing depth of the skin-wearing member 1 measured under the above conditions to be 1mm or more, the skin-wearing member 1 is easy to fit the skin and a high degree of comfort can be felt. If a cylindrical pressing jig with a diameter of 5mm is used to apply a load of 1N to the surface of the skin contact surface 2 of the skin-wearing member 1 in a direction perpendicular to the above surface, the pressing depth in the vertical direction is 5mm or more, the skin contact surface 2 fits the skin more closely and a higher degree of comfort can be felt.

[0078] Materials that can be used as the elastomer included in the skin-wearing component 1 include, for example, silicone, polystyrene, polyurethane, polyester, polyolefin, acrylic, polyvinyl chloride, etc. The elastomer included in the skin-wearing component 1 may also be, for example, a gel with polystyrene as the main material, a gel with silicone as the main material, or silicone rubber. A gel with polystyrene as the main material refers to a gel containing polystyrene as the largest component. The same is true for a gel with silicone as the main material. By making the elastomer a gel with polystyrene as the main material, a gel with silicone as the main material, or silicone rubber, it is safe for the organism, relatively inexpensive, and can provide a soft and comfortable touch.

[0079] In Embodiment 1, the skin wearing member 1 may also be formed of a polymer material including an elastomer. The polymer material may include, for example, polyolefin resins, vinyl resins, acrylic resins, polyester resins, polycarbonate resins, polystyrene resins, polyamide resins, epoxy resins, etc. as components other than the elastomer.

[0080] The care device 100 in this embodiment may be, for example, a care device that contacts or is worn on the skin around the face or neck. The care device 100 includes the skin wearing component 1 as described above, whereby the care device 100 can be contacted with or worn on the face or neck to provide a comfortable stimulation, thereby providing a beauty effect such as skin beautification on the skin around the face or neck.

[0081] The care device 100 in this embodiment may be, for example, a care device that contacts or is worn on the skin around the eyes. The care device 100 includes the skin-wearing member 1 as described above, and thus, by contacting or wearing the care device 100 around the eyes, a comfortable stimulation can be obtained, thereby eliminating eye fatigue and obtaining a beauty effect such as skin beautification on the skin around the eyes. In addition, by stimulating the area around the eyes, a sense of relaxation can be obtained and an effect of promoting sleep can be obtained.

[0082] The care device 100 is provided with a mechanism designed to apply appropriate physical stimulation or the like according to the body part of the person who contacts or wears the care device 100. In addition, such a mechanism can utilize a mechanism used in a known care device for various body parts of a person, such as a care device for the face, a care device for the neck area, and a care device for the eye area.

[0083] [1-2. Action]

[0084] The care device 100 configured as described above can be in contact with or worn on a person's skin via the skin-wearing member 1, thereby appropriately applying physical stimulation or the like corresponding to the body part of the person who is in contact with or wearing the care device 100. When the care device 100 is used, the person is in contact with the skin-wearing member 1. Therefore, the care device 100 can improve the comfort when in contact with the skin and when worn on the skin, and can obtain appropriate skin beautification and massage effects.

[0085] [1-3. Effects, etc.]

[0086] As described above, the care device 100 in Embodiment 1 is a care device that comes into contact with the skin or is worn on the skin. The care device 100 in Embodiment 1 includes a skin wearing component 1 that includes an elastomer. The skin wearing component 1 has an Asker C hardness of less than 30 and a static friction coefficient of less than 3. In Embodiment 1, the Asker C hardness and the static friction coefficient of the skin wearing component 1 are the Asker C hardness and the static friction coefficient of the surface of the skin wearing component 1 that comes into contact with the skin when the care device 100 comes into contact with the skin or is worn on the skin. Here, the static friction coefficient of the skin wearing component 1 is the static friction coefficient for an artificial skin sheet having the above-mentioned characteristics (A) and (B). As such an artificial skin sheet, for example, "BIOSKIN BPS-01L" manufactured by Regina Corporation can be used.

[0087] With such a structure, care device 100 in Embodiment 1 can improve the comfort when in contact with the skin and when worn on the skin.

[0088] In the first embodiment, the tensile strength of the skin wearing member 1 may be greater than 1 N / mm 2 By making the tensile strength of the skin-mounted component 1 greater than 1 N / mm 2 , so that it will not be damaged even when worn on the skin in a tension-applied manner, and can be used stably even after repeated use.

[0089] In Embodiment 1, the skin wearing component 1 may include, for example: a base material 11 including an elastomer; and a film 12 disposed at least in a region 11a facing the skin on the surface of the base material 11, the film 12 having a thickness of 100 μm or less. Since the skin wearing component 1 includes the film 12 disposed at least in the region 11a facing the skin on the surface of the base material 11, it is easy to reduce the static friction coefficient of the surface of the skin wearing component 1 that contacts the skin. In addition, by providing the film 12, the strength of the skin wearing component 1 can be improved, and as a result, the skin wearing component 1 is not easily damaged, the friction resistance is also enhanced, and the long-term durability of the skin wearing component 1 is improved.

[0090] In Embodiment 1, the adhesion between the substrate 11 and the film 12 is preferably 0.3 N or more in a peel test performed at a width of 15 mm. By setting the adhesion between the substrate 11 and the film 12 to 0.3 N or more, the following effects can be obtained: the film 12 can be prevented from peeling off from the substrate 11 during use, thereby preventing the formation of bubbles entering the interface and other appearance defects.

[0091] In Embodiment 1, the entire surface of the substrate 11 can be covered by the film. That is, the substrate 11 can be sealed by the film. By sealing the entire substrate 11 including the elastomer with the film, the film is not easily peeled off from the end of the skin wearing member 1 even when immersed in water or oil or when a strong force is applied.

[0092] In Embodiment 1, the care device 100 may further include a coating layer containing powder disposed on the surface of the skin contact surface 2 of the skin wearing member 1. The coating layer containing powder can provide a fresher touch and provide a high degree of comfort.

[0093] In Embodiment 1, when a 1N load is applied to the surface of the skin contact surface 2 of the skin wearing component 1 in a direction perpendicular to the surface using a cylindrical pressing jig having a diameter of 5 mm, the pressing depth in the vertical direction is expected to be 1 mm or more. According to this structure, when the care device 100 is brought into contact with the skin or worn on the skin, a load is applied to the skin wearing component 1 to deform the skin contact surface 2 to conform to the shape of the skin so that it can easily fit the skin. By making the skin contact surface 2 fit the skin, the person can strongly feel the touch of the skin contact surface 2 of the skin wearing component 1. By making the pressing depth of the skin wearing component 1 measured under the above conditions be 1 mm or more, the skin wearing component 1 can easily fit the skin and a high degree of comfort can be felt. If a cylindrical pressing jig with a diameter of 5 mm is used to apply a load of 1 N to the surface of the skin contact surface 2 of the skin wearing component 1 in a direction perpendicular to the above surface, and the pressing depth in the vertical direction is greater than 5 mm, the skin contact surface 2 will fit better with the skin, and a higher degree of comfort can be felt.

[0094] In Embodiment 1, the elastomer included in the skin wearing component 1 may be, for example, a gel mainly made of polystyrene, a gel mainly made of silicone, or silicone rubber. Since the elastomer is a gel mainly made of polystyrene, a gel mainly made of silicone, or silicone rubber, it is highly safe for the living body, relatively inexpensive, and can provide a soft and comfortable touch.

[0095] In Embodiment 1, the skin wearing member 1 may be formed of a polymer material containing an elastomer. With this structure, a soft and comfortable touch can be obtained at a relatively low price.

[0096] In the first embodiment, the care device 100 may be, for example, a care device that contacts or is worn on the skin around the face or neck. The care device 100 includes the skin wearing component 1 as described above, whereby the care device 100 can be contacted with or worn on the face or neck to provide a comfortable stimulation, thereby providing a beauty effect such as skin beautification on the skin around the face or neck.

[0097] In the first embodiment, the care device 100 may be, for example, a care device that contacts or is worn on the skin around the eyes. The care device 100 includes the skin-wearing member 1 as described above, and thus, by contacting or wearing the care device 100 around the eyes, a comfortable stimulation can be obtained, thereby eliminating eye fatigue and obtaining a beauty effect such as skin beautification on the skin around the eyes.

[0098] (Other embodiments)

[0099] As described above, the embodiments are described as examples of the technology disclosed in this application. However, the technology in the present disclosure is not limited thereto, and can also be applied to the embodiments obtained by changing, replacing, adding, omitting, etc. In addition, the constituent elements described in the above embodiments can also be combined to form new embodiments.

[0100] Therefore, other embodiments are exemplified below.

[0101] Figure 4 2 is a cross-sectional view showing a first modified example of the nursing device in Embodiment 1. Figure 4 As shown, the nursing device 200 as a first variant has a Figure 1 The care device 100 shown in the figure is also provided with a structure of a base member 5. In the care device 200, the base member 5 is arranged at a position on the opposite side of the skin wearing member 1 to the skin when the skin wearing member 1 is worn on the skin, and contacts at least a part of the part of the skin wearing member 1 that does not contact the skin. The part of the skin wearing member 1 that does not contact the skin is, for example, the surface of the skin wearing member 1 opposite to the skin contact surface 2. The 10% compressive stress of the base member 5 is 0.2 MPa or less. By making the 10% compressive load of the base member 5 0.2 MPa or less, the base member 5 is easily compressed when a load is applied to the surface of the skin contact surface 2 of the skin wearing member 1. Therefore, the surface of the skin contact surface 2 of the skin wearing member 1 is easily deformed, and when the care device 200 is brought into contact with the skin or worn on the skin, the skin contact surface 2 can be deformed to match the shape of the skin. As a result, the skin contact surface 2 is easy to fit more closely to the skin, and since the skin contact surface 2 fits closely to the skin, the person can strongly feel the touch of the skin contact surface 2 of the skin wearing component 1. In this way, by providing the base member 5, the skin wearing component 1 is easy to fit closely to the skin, and a high degree of comfort can be felt. When the 10% compressive stress of the base member 5 is less than 0.013 MPa, the base member 5 is more easily compressed when a load is applied to the surface of the skin contact surface 2 of the skin wearing component 1, and the skin wearing component 1 fits more closely to the skin, and a higher degree of comfort can be felt. In addition, the 10% compressive stress of the base member 5 can be measured by the method described in the embodiment described later.

[0102] It is desirable that the area of ​​the skin contact surface 2 of the skin wearing member 1 is larger than 4 cm 2 When the contact area with the skin is large, the touch of the skin wearing member 1 can be strongly felt. By making the area of ​​the skin contact surface 2 of the skin wearing member 1 larger than 4 cm 2When the care device 100 is in contact with the skin or worn on the skin, the touch of the skin wearing component 1 is easily felt, so that a high degree of comfort can be felt. When the area of ​​the skin contact surface 2 of the skin wearing component 1 is 9 cm 2 When the area of ​​the skin contact surface 2 of the skin wearing member 1 is 15 cm 2 When the area of ​​the skin contact surface 2 of the skin wearing member 1 is 25 cm 2 In the above case, it is easier to feel the touch of the member 1 on the skin, and a higher degree of comfort can be felt.

Figure 5 As shown, the nursing device 300 as a second variant has a Figure 1 The care device 100 shown in the figure is also provided with a structure of a heating element 6. The care device 300 has a heating element 6 capable of continuously controlling the temperature. By providing a heating element 6 capable of continuously controlling the temperature, the care device 300 can be used while feeling the warmth, thereby achieving an effect of further improving the comfort level. In addition, by warming the skin, blood circulation is improved, and beauty effects, massage effects, improved metabolism, and the like can be achieved, and a relaxing effect can be achieved by feeling the warmth. For example, there is no particular limitation on the location of the heating element 6, and it can be provided in any part of the care device 300. Furthermore, as Figure 5As shown, for example, when the skin wearing component 1 is worn on the skin, the heating element 6 can be arranged at a position on the side opposite to the skin wearing component 1, and arranged to contact at least a part of the part of the skin wearing component 1 that does not contact the skin. The part of the skin wearing component 1 that does not contact the skin is, for example, a position on the side opposite to the skin wearing component 1 when the skin wearing component 1 is worn on the skin, for example, the surface of the skin wearing component 1 opposite to the skin contact surface 2. By arranging the heating element 6 at a part of the part of the skin wearing component 1 that does not contact the skin, the heating element 6 can directly heat the skin wearing component 1. Therefore, a sense of temperature can be provided efficiently with low power. For example, the heating element 6 can also be arranged at any part of the care device 300, and the heating element 6 can be arranged to contact only a part of the part of the skin wearing component 1 that does not contact the skin when the skin wearing component 1 is worn on the skin. In this case, the heating element 6 is not provided on the skin wearing member 1 when not worn on the skin, so that the touch of the skin wearing member 1 becomes better when worn, and a sense of warmth can be provided efficiently with low power after wearing. For example, as the heating element, an electric heating wire heater, an infrared heater, a far infrared heater, a warm water heater, a jacket heater, a Peltier element, etc. are used.

[0104] It can also be, Figure 1 The care device 100 shown is also provided with a cooling control unit for cooling the skin-worn member 1.

The care device 400 includes a vibrator 7 that vibrates the skin-worn component 1. By providing the vibrator 7 that can vibrate the skin-worn component 1, the care device 400 can be used while performing massage using vibration, and in addition to the effect of improving comfort, muscles can also be relaxed. Therefore, according to the care device 400, fatigue reduction effects and beauty effects can be obtained. For example, the vibrator 7 can be provided in any part of the care device 400. As shown in FIG. Figure 6As shown, for example, when the skin wearing member 1 is worn on the skin, the vibrator 7 can be set at a position on the side opposite to the skin wearing member 1, and the vibrator 7 is set to contact at least a part of the part of the skin wearing member 1 that does not contact the skin. The part of the skin wearing member 1 that does not contact the skin is, for example, a position on the side opposite to the skin wearing member 1 when the skin wearing member 1 is worn on the skin, for example, the surface of the skin wearing member 1 opposite to the skin contact surface 2. By setting the vibrator 7 at a part of the part of the skin wearing member 1 that does not contact the skin, vibration can be directly applied to the skin wearing member 1. Therefore, vibration can be applied efficiently with low power. For example, the vibrator 7 can also be set at any part of the care device. The vibrator 7 can also be set to contact only a part of the part of the skin wearing member 1 that does not contact the skin when the skin wearing member 1 is worn on the skin. In this case, the vibrator 7 is not provided on the skin wearing member 1 when not worn on the skin, so that the touch of the skin wearing member 1 becomes better when worn, and vibration can be efficiently applied with low power after wearing.

The vibration auxiliary tool 8 is, for example, a part having a mass per unit area of ​​0.02 g / cm 2When such a vibration auxiliary jig 8 is provided, the vibration auxiliary jig 8 is vibrated by transmitting vibration to the vibration auxiliary jig 8. When the mass per unit area is large, the vibration applied to the skin of the portion where the vibration auxiliary jig 8 is provided becomes stronger. 2 When the vibration auxiliary jig 8 is composed of the above solid objects, the vibration applied to the skin of the part where the vibration auxiliary jig 8 is provided becomes stronger, thereby making the vibration feeling when the care device is in contact with the skin or worn on the skin stronger. In addition, when the overall mass of the vibration auxiliary jig 8 increases, the mass of the care device itself increases, and the weight is felt after wearing it, which becomes uncomfortable. When the overall mass of the vibration auxiliary jig 8 is less than 500g, the mass of the care device is not large, so it can be worn comfortably. The vibration auxiliary jig 8 can also have a mass per unit area of ​​0.03g / cm 2 In this case, the vibration applied to the skin of the portion where the vibration auxiliary tool 8 is provided becomes stronger. The vibration auxiliary tool 8 may also have a mass per unit area of ​​0.2 g / cm 2 In this case, the vibration applied to the skin of the portion where the vibration auxiliary jig 8 is provided becomes stronger.

In addition, the overall mass of the vibration auxiliary jig 8 can also be less than 100g. When the overall mass of the vibration auxiliary jig 8 is less than 100g, the mass of the care device becomes smaller and can be worn more comfortably.

[0312] (Preparation of skin-worn components)

[0313] A sheet of styrene elastomer (TANAC) was prepared as a substrate. A powder coating was applied to the surface of the sheet using a powder (WAKODO) containing talc as the main component. A skin-worn component formed by applying a powder coating to the substrate was prepared in this way. The Asker C hardness of the skin-worn component was 13 (C13), and the static friction coefficient against artificial skin was 1.4. This was used as the skin-worn component of Example 10.

[0314] (Tensile test)

[0315] When the care device is used, a tensile force is applied to the skin-worn member, and therefore the member needs to be durable against repeated tensile forces. Therefore, a tensile strength evaluation and a tensile durability test were performed on the skin-worn member.

[0316] In the tensile strength test, a test piece with a width of 5 mm and a length of 30 mm was prepared, and the stress at the time of breaking when stretched at a tensile speed of 100 mm / min was calculated using Autograph (EZ-L) manufactured by Shimadzu Corporation.

The tensile strength of the skin-worn component of Example 10 is 10.2 N·mm 2 , it was confirmed that there was no breakage until the stretching operation was performed 300 times.

[0317] <Example 11>

[0327] The results of Examples 10 to 12 are shown in Table 3. The case where there was no breakage until 300 stretching operations was performed was designated as A, and the case where there was breakage within 300 stretching operations was designated as B.

In this skin-wearing component, the sheet-like styrene elastomer is equivalent to a substrate containing an elastomer, and the film laminated with a polyurethane polymer film and a hot-melt layer is equivalent to a film disposed on the surface of the substrate. Regarding this skin-wearing component, the Asker C hardness and the static friction coefficient against humans were evaluated using the same method as in Example 1.

[0333] <Oil resistance evaluation>

[0334] Since the skin-worn components are used in contact with the skin, the swelling and exudation of the oil components on the skin or the cosmetic components applied to the skin are required to be small, and high oil resistance is required. As an evaluation of oil resistance, the skin-worn components were immersed in silicone oil at 50°C for 3 days, assuming that there were cosmetic components on the skin, and the oil resistance evaluation was implemented by evaluating the mass change rate from before to after immersion. For silicone oil, KF-96-100CS manufactured by Shin-Etsu Silicone was used to measure the mass after immersion after wiping off the oil attached to the skin-worn components. The mass of the skin-worn components of Example 13 after immersion decreased by 1% compared to before immersion.

The case where the mass change before and after the immersion in silicone oil was 10% or less was defined as oil resistance A, the case where the mass change was 50% or less was defined as oil resistance B, and the case where the mass change was greater than 50% was defined as C. The film is provided on the entire surface of the substrate including the elastomer, and the ends of the films are bonded to perform sealing, thereby improving the oil resistance.
