[0003] [Patent Document 1] JP 2016-190105 A Summary of the Invention [Problem to be solved by the invention]

[0004] In view of the above circumstances, the present invention provides a beauty method, a wearing body, and a beauty device set that can satisfactorily obtain a lift-up effect by hot and cold stimulation. [Means for solving the problem]

[0005] According to one aspect of the present invention, there is provided a cosmetic method, which comprises: fixing biological soft tissue in a lifted state against gravity with a mounting body; and applying hot and cold stimuli to the biological soft tissue with a cosmetic device while maintaining this state, thereby producing a lifting effect.

[Diagram 2] FIG. 2 is a schematic diagram showing a state in which the attachment of FIG. 1 is used. [Diagram 3] FIG. 2 is a cross-sectional view showing an example of a beauty device that can be used in the beauty method of the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, the beauty method, the attachment, and the beauty device set will be described in detail based on preferred embodiments. First, a mounting body that can be used in this embodiment will be described. [Wearing device] Fig. 1 is a plan view showing an example of a wearing body that can be used in the cosmetic method of the present embodiment, Fig. 2 is a schematic view showing the wearing body of Fig. 1 in use.

[0009] The wearing body 1 shown in Fig. 1 is a flexible sheet material that is used in contact with a living body. The wearing body 1 includes a long main body part 2 and a pair of fixing parts 3 that protrude laterally from both ends of the main body part 2 in the longitudinal direction. In such a wearing body 1, at least the main body part 2 is configured so that the expansion rate changes depending on the temperature in the temperature range of about 10°C to 50°C. With such a configuration, the main body part 2 can expand and contract (deform) with the body temperature of the living body, so that it can deform in accordance with the unevenness of the skin surface of the living body. Therefore, the wearing body 1 can be wrapped around various parts of the living body and worn on the skin surface with high adhesion. In addition, when the main body part 2 is cooled in a state where the body soft tissue is lifted against gravity by the main body part 2, the expansion rate of the main body part 2 decreases. This allows the body soft tissue to be fixed in a lifted state.

[0010] In the wearing body 1, the pair of fixing parts 3 are also preferably configured so that the expansion / contraction rate changes depending on the temperature in the temperature range of about 10° C. to 50° C. This allows the fixing parts 3 to expand and contract (deform) due to the body temperature of the living body, so that they can deform in accordance with the unevenness of the skin surface of the living body. The pair of fixing parts 3 may be fixed by hook-and-loop fasteners or snap-fits, but it is preferable that the pair of fixing parts 3 develop adhesiveness by heating and are fixed by contacting each other. This allows the number of parts to be reduced and the attachment body 1 to be easily fixed (attached) to the living body. The temperature range in which the expansion and contraction rate of the main body 2 and the fixing part 3 changes is more preferably about 12.5° C. to 45° C., and even more preferably about 15° C. to 40° C. In this case, it becomes easier to adjust the degree of deformation of the main body 2 and the fixing part 3 that depends on temperature.

[0011] The constituent material of the main body 2 and the fixing part 3 preferably contains an olefin resin as a main component (e.g., 95% by mass or more). By containing an olefin resin as a main component, it is easy to impart the above-mentioned properties to the entire attachment 1 (main body 2 and fixing part 3), and it is also possible to impart high water repellency. When the olefin resin is a multi-component olefin polymer (e.g., propylene-ethylene-α-olefin), the temperature-dependent expansion and contraction rate can be adjusted by adjusting the ratio of each monomer unit, the monomer sequence fraction, the degree of modification with maleic anhydride, etc. The temperature-dependent expansion and contraction rate of the entire wearing body 1 can be adjusted by the type and mixing ratio of other polymers mixed with the multicomponent olefin polymer. Examples of other polymers include polyethylene (ethene polymer), hydrogenated styrene-based thermoplastic elastomer, etc.

[0012] At the same temperature, the expansion rate of the main body part 2 is preferably greater than that of each fixing part 3. This allows the main body part 2 to be more securely fixed to the living body by the fixing parts 3 while improving the adhesion of the main body part 2 to the skin surface of the living body. Specifically, when the elongation percentage of the main body portion 2 at 23°C under a tensile stress of 6 MPa is X [%] and the elongation percentage of each fixing portion 3 at 23°C under a tensile stress of 6 MPa is Y [%], it is preferable that X / Y satisfies a relationship of about 5 or more and 50 or less, more preferably about 7.5 or more and 40 or less, and even more preferably about 10 or more and 30 or less. This can further improve the above-mentioned effects. The elongation (tensile strain) can be measured, for example, as follows. First, the sheet material to be checked for elasticity is cut into a strip of 25 mm width to prepare a test piece. Next, the test piece is gripped in the longitudinal direction by a tensile tester with a chuck distance of 30 mm, and pulled at a tensile speed of 1000% / min. The elongation percentage (%) can be calculated by: length of test piece when the tensile stress becomes 6 MPa (mm)-original length of test piece (mm) / original length of test piece (mm)×100.

[0013] The surface roughness of the main body 2 is preferably greater than the surface roughness of each of the fixing portions 3. This makes it possible to enhance the adhesiveness between the fixing portions 3 rather than the adhesiveness of the fixing portions 3 to the main body 2. In this specification, the term "surface roughness" refers to the arithmetic mean roughness (Ra) defined in JIS B 0601. Methods for making the surface roughness of the main body portion 2 greater than the surface roughness of each fixing portion 3 include, for example, a method in which the main body portion 2 is made of a foam sheet and the fixing portion 3 is made of a dense sheet, a method in which the surface of the main body portion 2 and / or the surface of the fixing portion 3 are physically or chemically surface-treated, and a method in which the degree of unevenness of the inner surface of the molding die that forms the main body portion 2 and the fixing portion 3 is changed.

[0014] The foam sheet (material) having the above-mentioned characteristics constituting the main body 2 can be self-produced, or a commercially available product such as HUMOFIT (registered trademark) F10 (manufactured by Mitsui Chemicals, Inc.), which contains more than 97% by mass of α-olefin copolymer and less than 3% by mass of polyethylene (ethene polymer), can be used. The foam sheet (material) constituting the main body 2 may be a commercially available product such as HUMOFIT (registered trademark) F20 (manufactured by Mitsui Chemicals, Inc.), which contains more than 49% by mass of hydrogenated styrene-based thermoplastic elastomer, less than 49% by mass of α-olefin copolymer, and less than 2% by mass of polyethylene (ethene polymer). On the other hand, the dense sheet (material) having the above-mentioned characteristics constituting the fixing part 3 can also be self-produced, or a commercially available product such as HUMOFIT (registered trademark) A11 (manufactured by Mitsui Chemicals, Inc.), which contains more than 99% by mass of α-olefin copolymer and less than 1% by mass of other substances, can be used. Furthermore, the material constituting the main body part 2 and the material constituting the fixing part 3 may each contain a shape memory polymer. In this case, it is possible to impart high shape memory properties to the attachment body 1 (the main body part 2 and the fixing part 3).

[0015] The wearing body 1 shown in Fig. 1 is used on the head. Specifically, the wearing body 1 is configured so that the main body part 2 contacts the lower jaw and its surroundings, and a pair of fixing parts 3 are disposed on the top of the head, as shown in Fig. 2. With this configuration, the cheek muscle tissue (biological soft tissue) can be fixed in a lifted state. In such a mounting body 1, the main body 2 has a first hole 21 in the center in the longitudinal direction, and a pair of second holes 22 between the first hole 21 and the pair of fixing parts 3. The first hole 21 and each of the second holes 22 are both oval in shape, and the size of the first hole 21 is smaller than the size of each of the second holes 22. 2, the chin (the tip of the lower jaw) can be inserted into the first hole 21, and the ears can be inserted into each of the second holes 22. With this configuration, the main body 2 is positioned relative to the face by the chin and ears, facilitating the attachment operation of the fixing part 3 to the top of the head.

[0016] An intersection I of center lines O of the two fixing parts 3 is configured to be located inside the first hole 21. The second hole 22 is disposed so as not to straddle the center line O. With this configuration, when the pair of fixing parts 3 are pulled and brought into contact with each other at the top of the head to be fixed, a tensile force can be easily applied to the attachment 1 (main body 2). The angle θ between the two center lines O is not particularly limited, but is preferably an obtuse angle, more preferably about 120° to 180°, and even more preferably about 130° to 170°. This makes it possible to more reliably apply a tensile force to the attachment 1 by pulling the pair of fixing parts 3. In the natural state of the attachment 1 (a state in which no external force is applied), the ratio of the first hole 21 and the two second hole 22 to the main body 2 is not particularly limited, but is preferably about 5% to 30%, and more preferably about 10% to 20%. This makes it possible to suitably prevent the mechanical strength of the main body 2 from decreasing.

[0017] The opening area of ​​the first hole 21 is not particularly limited, but is preferably 300 mm 2 More than 700mm 2 It is preferable that the thickness is about 400 mm or more. 2 More than 600mm 2 On the other hand, the opening area of ​​the second hole 22 is not particularly limited, but is preferably 1800 mm 2 More than 2200mm 2 It is preferable that the thickness is about 1900 mm or more. 2 More than 2100mm 2 It is more preferable that the above-mentioned condition is satisfied. In this case, the positioning operation and the mounting operation of the mounting body 1 can be performed more smoothly. The maximum length (maximum width) W2 in the longitudinal direction of the main body 2 is not particularly limited, but is preferably about 350 mm or more and 500 mm or less, and more preferably about 400 mm or more and 450 mm or less. Furthermore, the maximum length L2 in the short side direction of the main body 2 is not particularly limited, but is preferably about 75 mm or more and 175 mm or less, and more preferably about 100 mm or more and 150 mm or less.

[0018] The average width W3 of each fixing portion 3 is not particularly limited, but is preferably about 70 mm or more and 100 mm or less, and more preferably about 80 mm or more and 90 mm or less. Furthermore, the average length L3 of each fixing portion 3 is not particularly limited, but is preferably about 80 mm or more and 110 mm or less, and more preferably about 90 mm or more and 100 mm or less. The sheet constituting the main body 2 and the sheet constituting each fixing portion 3 are joined via a joint 23 formed by at least one of, for example, fusion (thermal fusion, ultrasonic fusion, high-frequency fusion, etc.), adhesion with an adhesive, and sewing. The width W23 of the joint portion 23 is not particularly limited, but is preferably about 5 mm or more and 20 mm or less, and more preferably about 7.5 mm or more and 15 mm or less.

[0019] The attachment 1 shown in FIG. 1 further includes a pair of second fixing parts 4 provided so as to protrude from the middle of the main body 2 in the longitudinal direction to the same side in the lateral direction. The characteristics of each of the second fixing parts 4 can be the same as the characteristics of each of the fixing parts 3. That is, the pair of second fixing parts 4 are also preferably configured so that their expansion and contraction rates change depending on temperature in the temperature range of 10° C. or more and 50° C. or less, and exhibit adhesiveness when heated. 2, the attachment 1 is fixed by bringing the main body 2 into contact with the lower jaw and its surroundings, pulling the pair of fixing parts 3 so that they come into contact with each other at the top of the head, and then pulling the pair of second fixing parts 4 so that they come into contact with each other at the back of the head. This allows the attachment 1 to be fixed to the head more accurately and reliably.

[0020] The average width W4 of each second fixing portion 4 is not particularly limited, but is preferably about 30 mm or more and 50 mm or less, and more preferably about 35 mm or more and 45 mm or less. Furthermore, the average length L4 of each second fixing portion 4 is not particularly limited, but is preferably about 35 mm or more and 50 mm or less, and more preferably about 40 mm or more and 45 mm or less. The sheet constituting the main body 2 and the sheet constituting each second fixing portion 4 are joined via a joint 24 formed by at least one of, for example, fusion (thermal fusion, ultrasonic fusion, high-frequency fusion, etc.), adhesion with an adhesive, and sewing. The width W24 of the joint portion 24 is not particularly limited, but is preferably about 5 mm or more and 20 mm or less, and more preferably about 7.5 mm or more and 15 mm or less.

[0021] The attachment body 1 shown in FIG. 1 further includes a pair of auxiliary parts 5 connected to both ends of the main body part 2 in the longitudinal direction, respectively, and provided overlapping the fixing parts 3. The characteristics of each auxiliary part 5 can be the same as the characteristics of each fixing part 3. That is, the pair of auxiliary parts 5 are also preferably configured so that their expansion and contraction rate changes depending on temperature in the temperature range of 10° C. or more and 50° C. or less, and exhibit adhesiveness by heating. 2, the attachment 1 is fixed by bringing the main body 2 into contact with the lower jaw and its surroundings, pulling the pair of fixing parts 3 so that they come into contact with each other at the top of the head, and then pulling the pair of auxiliary parts 5 so that they come into contact with the fixing parts 3 at the top of the head. This increases the clamping force of the attachment 1 on the cheek (living body). Each auxiliary part 5 has a rectangular shape (rectangular shape) and is disposed so that its longitudinal direction is approximately parallel to the center line O. With this configuration, the operation of increasing the tightening force of the attachment body 1 on the living body can be easily performed.

[0022] The average width W5 of each auxiliary portion 5 is not particularly limited, but is preferably about 25 mm or more and 45 mm or less, and more preferably about 30 mm or more and 40 mm or less. Furthermore, the average length L5 of each second fixing portion 4 is not particularly limited, but is preferably about 115 mm or more and 155 mm or less, and more preferably about 125 mm or more and 145 mm or less. The sheet constituting the main body 2 and the sheet constituting each second fixing portion 4 are joined via a joint 25 formed by at least one of, for example, fusion (thermal fusion, ultrasonic fusion, high-frequency fusion, etc.), adhesion with an adhesive, and sewing.

[0024] Next, a cosmetic device that can be used in this embodiment will be described. [Beauty device] FIG. 3 is a cross-sectional view showing an example of a cosmetic device that can be used in the cosmetic method of the present embodiment. The cosmetic device 10 shown in Fig. 3 is a device for applying hot and cold stimuli to a living body. For convenience of explanation, the upper side in Fig. 3 will be referred to as "upper" or "upper side" and the lower side will be referred to as "lower" or "lower side". This beauty device 10 comprises a housing 20, a partition section 30 that divides the housing 20 into upper and lower sections, a Peltier element 40 and a power supply section 50 arranged to penetrate the partition section 30, a control board 60, and a charging section 70. According to this configuration, one side of the housing 20 can be heated and the other side can be cooled by the action of the Peltier element 40. The partition wall 30 also has a function of separating (separating) the housing 20 into a heating side and a cooling side.

[0025] The power supply unit 50 can be composed of, for example, a storage battery such as a lithium secondary battery. Furthermore, charging unit 70 can be configured, for example, by a non-contact charging coil, a charging cable, and the like. It is preferable that the beauty device 10 is configured to automatically turn on when the power supply to the power supply unit 50 via the charging unit 70 ends, and to automatically turn off when the power supply starts. With this configuration, the power button can be omitted. It is also preferable to omit the level adjustment button, the mode change button, and also the display unit (LED elements), etc. This allows the configuration of the beauty device 10 to be extremely simplified.

[0026] [Beauty equipment set] One embodiment of the cosmetic device set can be configured to include the attachment 1 and the cosmetic device 10 as described above. [Beauty method] The beauty method can be carried out, for example, by using such a beauty device set. The cosmetic method of this embodiment involves fixing biological soft tissue in a lifted state against gravity using a wearing body 1, and while maintaining this state, applying hot and cold stimuli to the biological soft tissue using a cosmetic device 10 to produce a lifting effect. Specifically, first, the wearing body 1 is worn on the head as shown in Fig. 2. This causes the biological soft tissue, which is the muscle tissue of the cheek of the head, to be fixed in a lifted (pulled up) state.

[0027] Next, the beauty device 10 is operated, and hot and cold stimulation from the beauty device 10 is applied to the muscle tissue (soft biological tissue) of the cheek via the wearable body 1 (main body 2). By heating and cooling the muscle tissue via the main body 2 in this way, the temperature of the heating and cooling can be slowly applied to the muscle tissue. This effect is particularly well obtained when the main body 2 is made of a foamed sheet as described above. In addition, the heating side of the cosmetic device 10 is first pressed against the main body 2, and the expansion rate is increased while stretching the main body 2 like an iron, so that the main body 2 can be deformed to follow the shape of the face. Next, the cooling side of the cosmetic device 10 is pressed against the main body 2, and the contraction rate is reduced and solidified, so that the muscle tissue of the cheek can be memorized as being lifted against gravity. This allows the muscle tissue to be pressurized and lymphatic drainage to be performed. After that, when the cooling by the cosmetic device 10 is finished, the expansion rate of the main body 2 gradually increases due to the body temperature, and the pressure on the muscle tissue is released, allowing the lymph to be released.

[0028] The temperature difference between the first temperature during heating by hot and cold stimulation and the second temperature during cooling is preferably about 10° C. to 50° C., more preferably about 15° C. to 40° C., and even more preferably about 20° C. to 35° C. In this case, the change in the expansion and contraction rate of the main body 2 can be made sufficiently large. Specifically, it is preferable that the first temperature is about 40±10° C. (particularly, about 40±5° C. or about 40±3° C.) and the second temperature is about 10±10° C. (particularly, about 10±5° C. or about 10±3° C.). In this case, the above-mentioned effects can be more satisfactorily obtained. As described above, the main component of the material of the main body 2 and the fixing part 3 is an olefin resin, which can impart high water repellency to the main body 2 and the fixing part 3. This allows the main body 2 to have a wrapping effect on the skin surface, and if a beauty ingredient (e.g., a moisturizing ingredient) is interposed between the skin surface and the main body 2, a high penetration effect of the beauty ingredient can be expected.

[0029] The cosmetic ingredient may be directly interposed between the skin surface and the main body portion 2, or may be interposed between the skin surface and the main body portion 2 in a state in which the cosmetic ingredient is supported by an absorbent substrate. Examples of beauty ingredients include various vitamins, ceramides, collagen, whitening agents, etc. The water-absorbent substrate may preferably be composed of at least one of a woven fabric, a nonwoven fabric, and a gel sheet. The absorbent substrate carrying the cosmetic ingredient may be a commercially available sheet mask. Furthermore, the absorbent base material (second layer) carrying the cosmetic ingredient does not have to be joined to the wear body 1 (first layer), and may be joined, for example, by at least one of fusion (thermal fusion, ultrasonic fusion, high-frequency fusion, etc.), adhesion with an adhesive, and sewing.

[0030] Furthermore, the second layer may be an electrode layer that imparts an electrical stimulus to the living body, instead of an absorbent substrate that supports a cosmetic ingredient. The electrode layer is preferably made of at least one of conductive silicone, metal foil, metal fiber, conductive resin ink, and metal ink, for example. Moreover, the electrode layer preferably has a resin base material and an electrode provided on the side of the base material opposite to the mounting body 1. In this case, the base material can be composed mainly of a silicone resin or silicone rubber. Also, a second layer composed mainly of silicone resin or silicone rubber can be provided corresponding to the main body portion 2. In this case, the attachment 1 (first layer) may further include a third layer corresponding to the main body 2. This third layer is provided on the opposite side of the attachment 1 (first layer) to the second layer, and can be composed mainly of silicone resin or silicone rubber.

[0031] The biological soft tissue to which the hot and cold stimulation is applied to produce a lifting effect by wearing the wearing body 1 is not limited to muscle tissue of the head, but may be muscle tissue of the upper arm, thigh, or buttocks. In these cases, the shape and size of the main body 2, the position, shape and size of the fixing part 3, the presence or absence, position, shape and size of the second fixing part 4, the presence or absence, position, shape and size of the auxiliary part 5, etc. may be set appropriately. Furthermore, when the wearing body 1 is used on the upper arm, it is preferable to form a hole into which the elbow is inserted, and when the wearing body 1 is used on the thigh, it is preferable to form a hole into which the knee is inserted. The wearing body 1 may be configured to cover the entire face or the lower half of the face of the user. In this case, the wearing body 1 is provided with openings (holes) or recesses (notches) corresponding to the eyes, nose, and mouth, respectively.

EXAMPLES

[0065] The cosmetic method will be described in more detail below using the following examples, but is not limited to the following examples.

[0066] Ten subjects (women, aged 23 to 51) participated in the test. The subjects were asked to answer whether they felt an improvement in swelling and a lifting effect in either Test I, in which the wearable device 1 was used alone, or Test II, in which the wearable device 1 was used while the beauty device 10 was used to apply hot and cold stimulation, respectively.

[0067] The attachment 1 used had the following specifications: Main body 2 Material: HUMOFIT (registered trademark) F10 (manufactured by Mitsui Chemicals, Inc.) Thickness: 0.5mm Fixed part 3, second fixed part 4 and auxiliary part 5 Material: HUMOFIT (registered trademark) A11 (manufactured by Mitsui Chemicals, Inc.) Thickness: 0.4mm

[0068] First, 10 subjects were divided into two groups, X and Y, each consisting of 5 subjects. The subjects in Group X were asked to remove their makeup using a cleansing product, then they underwent Test I, took a 30-minute break, and then performed Test II. On the other hand, the subjects in Group Y removed their makeup with a cleansing product, then performed Test II, took a 30-minute break, and then performed Test I.

[0069] In test I, first, the chin was inserted into the first hole 21 of the wearing body 1, the fixing part 3 was pulled and slowly pulled up along the face line, and then the ear was inserted into the second hole 22 and the fixing part 3 was fixed at the top of the head. Next, the second fixing part 4 was pulled and pulled up, and then fixed at the back of the head, and the auxiliary part 5 was pulled and fixed to the fixing part 3 at the top of the head. The adjustment was made so that the throat was not too uncomfortable. This state was maintained for 6 minutes. On the other hand, in Test II, while the attachment 1 was attached as in Test I, the attachment was heated on the heating surface (42°C) of the cosmetic device 10 for 3 minutes, and then cooled on the cooling surface (12°C) for 3 minutes.

[0070] The results are shown in Table 1 below. [Table 1]

[0071] In this test, 10 out of 10 people felt more effective when they used hot and cold stimulation in combination with the wearable device 1. This shows that by using hot and cold stimulation in combination, it is possible to take advantage of the temperature-dependent characteristics of the wearable device 1 and obtain beauty effects such as reducing swelling and making the face look slimmer, as well as lifting the skin.
