[0009] It is preferable that a cosmetic tool can achieve a high blood flow promoting effect when used. Although the cosmetic tool described in Patent Document 1 can achieve a blood flow promoting effect by pressing the cosmetic tool against the skin, there is a need for a technology that can easily achieve an even higher blood flow promoting effect. Therefore, the present invention relates to a cosmetic tool that can more effectively promote blood flow and a cosmetic method using the cosmetic tool.

[0010] After extensive research, the inventors discovered that by tapping the surface of the human body to which a liquid has been applied with a beauty tool having a specific shape, it is possible to more effectively promote blood flow while providing a moderate sensation of stimulation.

[0011] The present invention will be described below based on preferred embodiments. First, the beauty tool of the present invention (hereinafter also referred to as "beauty tool 1") will be described with reference to preferred embodiments. The beauty tool 1 of the present invention is used to effectively promote blood flow to the human body surface S, such as the skin on the face, arms, hands, feet, back, etc.

[0012] The cosmetic tool 1 of the present invention typically has one or more protrusions 3 protruding from a base surface 2. The cosmetic tool 1 of the present invention typically has a flat sheet-like shape as a whole, and has one or more protrusions 3 protruding from one surface of the sheet-like substrate. In this embodiment, the surface of the sheet-like substrate from which the protrusions 3 protrude is the base surface 2, and the portion of the substrate other than the protrusions 3 is the sheet base 7.

[0013] The tip diameter WA of the protrusions 3 of the cosmetic tool used in the cosmetic method using the cosmetic tool of the present invention is preferably 10 μm or more, more preferably 50 μm or more. This makes it possible to prevent damage to the stratum corneum by the protrusions 3 when tapping the human body surface S with the cosmetic tool 1, prevent excessive irritation, and improve the effect of lifting the human body surface S together with the liquid L. Furthermore, the tip diameter WA of the protrusions 3 of the cosmetic tool is preferably 1,000 μm or less, more preferably 800 μm or less, and even more preferably 600 μm or less. This makes it possible to promote blood flow to the skin with a smaller pressing force and to impart a pleasant irritating sensation. For these reasons, the tip diameter WA of the protrusions 3 is preferably 10 μm or more and 1,000 μm or less, more preferably 50 μm or more and 800 μm or less, and even more preferably 50 μm or more and 600 μm or less. When the tip diameter of the cosmetic tool 1 is small, it is preferable to adjust the pressure applied to the cosmetic tool 1 to reduce the tapping pressure from the viewpoint of non-invasiveness. To ensure non-invasiveness regardless of the strength of the tapping force or the tapping method, it is preferable that the tip diameter WA of the protrusions 3 be relatively large so that the tips are not extremely sharp. From this viewpoint, the tip diameter WA of the protrusions 3 is preferably 50 μm or more, more preferably 100 μm or more, even more preferably 150 μm or more, even more preferably 200 μm or more, and even more preferably 300 μm or more. From the above viewpoints, the tip diameter WA of the protrusions 3 is preferably 50 μm or more and 1,000 μm or less, more preferably 100 μm or more and 800 μm or less, even more preferably 150 μm or more and 800 μm or less, even more preferably 200 μm or more and 600 μm or less, and even more preferably 300 μm or more and 600 μm or less.

[0014] The height H of the protrusions 3 is 3,000 μm or less, preferably 2,500 μm or less, and more preferably 2,000 μm or less. This makes it difficult for the protrusions 3 to damage the stratum corneum when the cosmetic tool 1 is used to tap the human body surface S. Furthermore, the height H of the protrusions 3 is greater than 0 μm, preferably greater than 50 μm, more preferably greater than 100 μm, and even more preferably greater than 200 μm. This allows for efficient promotion of blood flow and efficient application of the liquid material L to the human body surface S. For these reasons, the height H of the protrusions 3 is preferably greater than 0 μm and less than 3,000 μm, more preferably greater than 50 μm and less than 2,500 μm, even more preferably greater than 100 μm and less than 2,000 μm, and even more preferably greater than 200 μm and less than 2,000 μm. The degree of the blood flow promoting effect can be determined by various known methods. For example, it is preferable to judge whether or not a flare reaction occurs in the skin, or to judge by visualizing the blood flow distribution using a laser blood flow meter (LSFG). It is preferable that the protrusions 3 have convex curved tips from the viewpoint of preventing damage to the skin.

[0015] The tip diameter WA of the protrusions 3 can be measured using the following measurement method. <Method for Measuring the Tip Diameter WA of the Protrusions 3> First, a case where both side edges 3a, 3b of the protrusions 3 rising from the base surface 2 are straight will be described. The cosmetic tool 1 is cut along the normal direction of the base surface 2 to obtain a sheet piece on which the cut surface of the protrusions 3 is exposed. Next, the protrusions 3 on the cut surface are observed using a microscope at a predetermined magnification to obtain an observation field image. Next, as shown in Figures 3(a) and 3(b), an imaginary straight line ILa is extended along the straight portion of one side edge 3a of the both side edges 3a, 3b. Next, an imaginary straight line ILb is extended along the straight portion of the other side edge 3b. Then, on the tip side, the point where one side edge 3a deviates from the imaginary straight line ILa is determined as a first tip point 3a1, and the point where the other side edge 3b deviates from the imaginary straight line ILb is determined as a second tip point 3b1. The length of the straight line connecting the first tip point 3a1 and the second tip point 3b1 thus determined is measured. The measurement is carried out for three protrusions 3 arbitrarily selected from the base surface 2, and the average value thereof is taken as the tip diameter WA of the protrusion 3.

[0016] Next, a case will be described in which both side edges 3a, 3b of the protrusion 3 rising from the base surface 2 are curved. For example, as shown in Figure 3(c), there is a case in which the protrusion 3 has a bulging portion 35 that bulges outward in the radial direction. In this case, the length of the maximum diameter portion 34 is defined as the tip diameter WA.

[0017] The cosmetic tool 1 of the present invention preferably has one or more discharge holes 4. The cosmetic tool 1 preferably includes a protrusion 3 having a discharge hole 4. Examples of the protrusion 3 having a discharge hole 4 include a protrusion having an opening at the tip or outer surface of the side of the protrusion 3 through which the liquid material L is discharged. This opening is an outlet through which the liquid material L is discharged through the discharge hole 4 and is referred to as a discharge outlet 41. The opening on the opposite side of the discharge outlet 41, i.e., at the tip or inner surface of the side of the protrusion 3, is referred to as a discharge inlet 42. The discharge inlet 42 is an inlet for the liquid material to be discharged through the discharge hole 4. An example of a protrusion 3 having a discharge inlet 42 at its tip is shown in FIG. 4( a). An example of a protrusion 3 having a discharge inlet 42 on its side is shown in FIG. 4( b). Note that the tip of the protrusion 3 refers to the region on the tip side of the protrusion 3 below the 0.8 position when the height of the base surface 2 is 0 and the height of the protrusion 3 is 1. The side of the protrusion 3 refers to the region on the base surface 2 side below the 0.8 position when the height of the base surface 2 is 0 and the height of the protrusion 3 is 1. In the protrusions 3 having discharge inlets 42, the discharge holes 4 are through-holes that penetrate the sheet base 7 and the protrusions 3 in the thickness direction of the sheet base 7 and the protrusions 3. The hollow portions 30 of the protrusions 3 function as passages for the liquid material L that is discharged to the outside from the discharge inlets 42. The center positions of the discharge inlets 42 on the side surfaces of the protrusions 3 are preferably located in an area of ​​a predetermined height on the side surface toward the base surface 2. When the height of the base surface 2 is 0 and the height of the protrusions 3 is 1, the predetermined height area is preferably 0.3 to 0.8, more preferably 0.5 to 0.7.

[0018] The discharge hole 4 typically has a circular shape when viewed from the side opposite the discharge hole 4. The shape of the discharge hole 4 when viewed from the side opposite the discharge hole 4 is not particularly limited and may be rectangular, elliptical, or the like. From the viewpoint of uniformity of the discharge pressure at the discharge hole 4, the shape of the discharge hole 4 when viewed from the side opposite the discharge hole 4 is preferably circular. From the viewpoint of enabling a large hole diameter and easily discharging a highly viscous liquid material L, the shape of the discharge hole 4 when viewed from the side opposite the discharge hole 4 is preferably elliptical. When the shape of the discharge hole 4 when viewed from the side opposite the discharge hole 4 is elliptical, the ratio of the minor axis to the major axis (minor axis / major axis) is preferably greater than 0 and less than 1, more preferably 0.9 or less. The diameters of the ellipse, i.e., the inner diameters D1 and D2, are equivalent circle diameters converted into the diameters of perfect circles with the same cross-sectional area.

[0019] The inner diameter D2 of the discharge inlet 42 is preferably 10 μm or more, more preferably 50 μm or more. This improves dischargeability when the liquid material L is discharged from the cosmetic tool 1 and supplied to the human body surface S. From the viewpoint of maintaining the shape and / or strength of the protrusions, the inner diameter D2 of the discharge inlet 42 in the discharge hole 4 is preferably 200 μm or less, more preferably 150 μm or less.

[0020] The cosmetic tool 1 of the present invention can non-invasively tap the human body surface S because the tip diameter WA of the protrusions 3 is within the above-mentioned range. The cosmetic tool 1 of the present invention is preferably used for non-invasive tapping of the human body surface S. The human body surface S generally has the epidermis, including the stratum corneum, and the dermis, which are arranged from the surface to the interior. In the present invention, "non-invasive" refers to a state in which the stratum corneum of the human body surface S is not damaged even when the cosmetic tool is pressed against the human body surface S. The cosmetic tool 1 of the present invention is preferably used for tapping the human body surface S while supplying a liquid material L to the human body surface S. If the cosmetic tool 1 has an outlet hole 4, the liquid material L can be discharged from the outlet hole 4 and used for tapping. This allows the liquid material L to efficiently penetrate the human body surface S while providing a moderate stimulating sensation and effectively promoting blood flow. In this way, the cosmetic tool 1 of the present invention can effectively promote blood flow while providing a moderate stimulating sensation and minimizing damage to the human body surface S.

[0021] The base surface 2 has a first direction X and a second direction Y perpendicular to the first direction X in a plan view (see FIG. 1 ). The base surface 2 typically has a plurality of protrusions 3 arranged in a dispersed state in a plan view. That is, the plurality of protrusions 3 are arranged in a dispersed state in the first direction X and the second direction Y. Here, "a plurality of protrusions 3" means two or three or more protrusions 3. The base surface 2 typically has a protrusion row 3L in which the plurality of protrusions 3 are arranged at intervals along the second direction Y. The protrusion rows 3L are typically provided in multiple rows spaced apart in the first direction X. The positions of the protrusions 3 constituting the protrusion row 3L adjacent to each other in the first direction X in the second direction Y may coincide with each other (see FIGS. 1 and 6( a)). Here, "multiple protrusion rows 3L" means two or three or more protrusion rows 3L. Alternatively, the cosmetic tool 1 may have only one protrusion row 3L.

[0022] The base surface 2 typically has a protrusion arrangement region 3R in which a plurality of protrusions 3 are arranged. For example, in the example shown in FIG. 1 , the protrusion arrangement region 3R is a region in which a plurality of the aforementioned protrusion rows 3L are arranged. The contour shape of the protrusion arrangement region 3R in a plan view can be any shape, such as a circle, an ellipse, a rectangle, a hexagon, or a substantially square shape with rounded corners. The contour shape of the protrusion arrangement region 3R is the contour shape of a region defined by a virtual line K connecting the outer edges of the protrusions 3 located most outward in either or both of the first direction X and the second direction Y in a plan view.

[0023] The protrusion arrangement region 3R is typically formed in a part of the base surface 2. That is, the base surface 2 of this embodiment has a protrusion arrangement region 3R in which a plurality of protrusions 3 are formed, and a non-protrusion arrangement region in which no protrusions 3 are formed. In the base surface 2, typically, the protrusion arrangement region 3R is surrounded by the non-protrusion arrangement region in a plan view. This makes it difficult for pressure to be dispersed when tapping the surface of the human body with the cosmetic tool 1, and the blood flow promotion effect can be more easily achieved with a small force. From the viewpoint of more reliably achieving the above-mentioned effect, when the cosmetic tool 1 is viewed in a plan view, the unit area (1 cm) of the protrusion arrangement region 3R is set to 1 / 2. ２ In order to more easily obtain the blood flow promoting effect with a small force, the number N of the protrusions 3 is preferably 600 / cm. ２ Less than or equal to 400 particles / cm, more preferably ２ From the viewpoint of preventing damage to the stratum corneum, the number N of the protrusions 3 is preferably 10 / cm ２ More preferably, 50 particles / cm ２ The number N of the protrusions 3 can be calculated by the following method.

[0024] <Method of calculating the number N of protrusions 3> When the beauty tool 1 is viewed from above, the total area (cm ) of the protrusion arrangement region 3R in which the protrusions 3 are arranged in a dispersed manner in the planar direction is calculated. ２ ) and the number of protrusions 3 included in the region. From these values, the number N of protrusions 3 can be calculated by dividing the area of ​​the protrusion arrangement region 3R by the number of protrusions.

[0025] In order to facilitate accurate stimulation of the intended location with the projections 3, the area ratio of the projection arrangement region 3R to the base surface 2 is preferably 20% or more, more preferably 30% or more, when the cosmetic tool 1 is viewed in plan. In order to more easily obtain the blood flow promoting effect with a small force, the area ratio is preferably 80% or less, more preferably 70% or less.

[0026] The total number of protrusions 3 is preferably 6 or more, more preferably 15 or more, and even more preferably 30 or more. This makes it possible to stimulate a wide area at once. The total number of protrusions 3 is preferably 300 or less, more preferably 150 or less, and even more preferably 80 or less. This makes it possible to accurately stimulate the desired location and also to appropriately stimulate uneven areas such as the face. For the above reasons, the total number of protrusions 3 is preferably 6 to 300, more preferably 15 to 150, and even more preferably 30 to 80.

[0027] When the cosmetic tool 1 is viewed in plan, the distance D between the centers of adjacent protrusions 3 is preferably 0.2 mm or more, more preferably 0.5 mm or more. This allows the skin to be tapped without being affected by skin deformation when adjacent protrusions are pressed against the skin. The distance D is preferably 3 mm or less, more preferably 2 mm or less. This allows the blood flow improvement effect associated with adjacent protrusions to be obtained throughout the application range without gaps. As in the embodiment shown in FIG. 1 , assume that the protrusions 3 are adjacent in both the first direction X and the second direction Y. The distance between the centers of adjacent protrusions 3 in the first direction X is Dx, and the distance between the centers of adjacent protrusions 3 in the second direction Y is Dy. In this case, only one of the distances Dx and Dy may be within the above-mentioned range, or both may be within the above-mentioned range (see FIG. 6( a)).

[0028] In the beauty tool 1 of the present invention, the positions of the protrusions 3 constituting adjacent protrusion rows 3L in the first direction X do not have to coincide with each other in the second direction Y. In this case, typically, the phases of the arrangement of the protrusions 3 in the protrusion rows 3L adjacent to each other in the first direction X are shifted, and the protrusions 3 are arranged in a staggered pattern overall. An example of this is shown in Figure 6(b). When the positions in the second direction Y of the protrusions 3 constituting adjacent protrusion rows 3L in the first direction X do not coincide with each other, the distance Dx between the centers of the protrusions 3 adjacent to each other in the first direction X is defined as the distance along the first direction X between the protrusions 3 constituting adjacent protrusion rows 3L in the first direction X.

[0029] As a result of extensive research, the present inventors have found that tapping the human body surface S with a beauty tool 1 having protrusions 3 of different heights can promote blood flow more effectively. More specifically, they have found that tapping the human body surface S with a beauty tool 1 having two types of protrusions 3 of different heights can promote blood flow more effectively. An embodiment of a beauty tool 1 having two types of protrusions 3 of different heights will be described.

[0030] The protrusions 3 preferably have first protrusions 31 and second protrusions 32, each of which is taller than the second protrusions 32. When the protrusions 3 have first protrusions 31 and second protrusions 32, the tip diameter WA of the first protrusions 31 is preferably within the above-mentioned range. The tip diameter WA of the second protrusions 32 is preferably 50 μm or more, more preferably 100 μm or more, and even more preferably 150 μm or more. This makes it possible to prevent damage to the stratum corneum by the second protrusions 32 and improve the effect of lifting the human body surface S together with the liquid L. Furthermore, the tip diameter WA of the second protrusions 32 is preferably 1,000 μm or less, more preferably 700 μm or less, and even more preferably 500 μm or less. This makes it possible to promote blood flow to the skin with a smaller tapping pressure and provide a pleasant stimulating sensation.

[0031] When the first protrusions 31 and the second protrusions 32 are provided, the height H1 of the first protrusions 31 is preferably within the range of the height H described above. The height H2 of the second protrusions 32 is preferably 10 μm or more, more preferably 100 μm or more. This allows for efficient promotion of blood flow and efficient application of the liquid material L to the human body surface S. Furthermore, the height H2 of the second protrusions 32 is preferably 2,000 μm or less, more preferably 1,000 μm or less. This prevents damage to the stratum corneum by the protrusions 3 when tapping the human body surface S with the cosmetic tool 1. For these reasons, the height H2 of the second protrusions 32 is preferably 10 μm or more and 2,000 μm or less, more preferably 100 μm or more and 1,000 μm or less. The ratio of the height H1 of the first protrusions 31 to the height H2 of the second protrusions 32 (H1 / H2) is preferably 1 or more, more preferably greater than 1, and even more preferably 1.2 or more. This allows for effective promotion of blood flow. Furthermore, when tapping the human body surface S, contact between the discharge outlet 41 and the human body surface S can be prevented, thereby ensuring the dischargeability of the liquid material L. In addition, the liquid material L can be efficiently applied to the human body surface S. Furthermore, the ratio (H1 / H2) is preferably 30 or less, and more preferably 10 or less. This makes it easier for the liquid material L discharged from the discharge outlet 41 to reach the human body surface S, and allows it to be efficiently supplied to the human body surface S. For the above reasons, the ratio (H1 / H2) is preferably 1 or more and 30 or less, more preferably more than 1 and 10 or less, and even more preferably 1.2 or more and 10 or less.

[0032] The ratio WA / H1 of the tip diameter WA of the primary projections 31 to the height H1 of the primary projections 31 is preferably 0.05 or more, more preferably 0.1 or more, and even more preferably 0.3 or more. This more reliably achieves the effect of suppressing damage to the stratum corneum while achieving the blood flow promoting effect when the cosmetic tool 1 is applied to the human body surface S. Furthermore, the ratio WA / H1 is preferably 5 or less, more preferably 1 or less, and even more preferably 0.6 or less. This allows the blood flow promoting effect to be achieved with even easier operation. For the above reasons, the ratio WA / H1 is preferably 0.05 or more and 5 or less, more preferably 0.1 or more and 1 or less, and even more preferably 0.3 or more and 0.6 or less.

[0033] The height H of the protrusions 3 refers to the distance along the thickness direction Z of the sheet base 7 from the surface of the base 2 on which the protrusions 3 protrude to the tip of the protrusions 3, and can be measured by the following method. <Method for measuring the height of the protrusions> The base 2 is cut to obtain a sheet piece on which the cut surface of the protrusions 3 appears, as shown in Figure 4. Next, the protrusions 3 on the cut surface are observed using a microscope at a predetermined magnification to obtain an image of the observation field. Next, the distance along the thickness direction Z of the sheet base 7 from the base 2 to the tip of the protrusions 3 is measured. The distance measured in this way is the height H of the protrusions.

[0034] The protrusions 3 may include first protrusions 31 that are taller than the second protrusions 32 and do not have discharge holes 4, and second protrusions 32 that have discharge holes 4. In this case, the discharge holes 4 of the second protrusions 32 preferably have openings serving as discharge outlets 41 at the tip or side of the protrusions 32. As an example, FIG. 4( a) shows an example in which the discharge holes 4 are at the tip of the second protrusions 32, and FIG. 4( b) shows an example in which the discharge holes 4 are at the side of the second protrusions 32. When the cosmetic tool 1 is used to tap the human body surface S, it is preferable to prevent the opening from being blocked by the human body surface S and enable continuous discharge of the liquid material L. From this perspective, it is preferable that the discharge holes 4 of the second protrusions 32 have discharge outlets 41 on the side of the protrusions 32. With this configuration of the cosmetic tool 1, when the human body surface S is tapped with the cosmetic tool 1, the first protrusions 31 can tap the human body surface S while discharging the liquid material L from the second protrusions 32. This allows the liquid material L to be supplied from the second protrusions 32 to the human body surface S even when the first protrusions 31 are pressed against the skin. When the cosmetic tool is used in a vertical position, supplying the liquid material L from the human body surface S can further prevent the liquid material L from dripping. This makes it possible to efficiently supply the liquid material L to the human body surface S. Furthermore, since the liquid material L can be applied evenly to the human body surface S, the liquid material L can be more efficiently penetrated into the skin. The first protrusions 31 may have a shape including a bulging portion 35 and a constricted portion 38, which will be described later.

[0035] As shown in FIGS. 4( a), 4(b), and 5, the discharge holes 4 may be formed such that the opening area S1 of the inner diameter D1 formed on the outer surface of the protrusion 3 is larger than the opening area S2 of the inner diameter D2 formed on the inner surface of the protrusion 3. That is, the discharge holes 4 are formed such that the inner diameter D1 on the outer surface of the protrusion 3 is larger than the inner diameter D2 on the inner surface of the protrusion 3. Note that the outer inner diameter refers to the inner diameter of the discharge outlet 41, and the inner inner diameter refers to the inner diameter of the discharge inlet 42. From the viewpoint of stably discharging the liquid material L through the discharge holes 4, the opening diameter D1 on the outer surface of the discharge holes 4 is preferably 10 μm or more, more preferably 20 μm or more. Furthermore, from the viewpoint of maintaining the strength of the protrusions 3, the outer inner diameter D1 of the discharge holes 4 is preferably 600 μm or less, more preferably 450 μm or less. From the above, the inner diameter D1 of the outer surface side of the discharge hole 4 is preferably 10 μm or more and 600 μm or less, and more preferably 20 μm or more and 450 μm or less.

[0036] The opening diameter D2 on the inner surface side of the discharge hole 4 is preferably 10 μm or more, more preferably 50 μm or more. This prevents clogging of the liquid when the liquid material L is discharged from the cosmetic tool 1 and supplied to the human body surface S, thereby improving discharge performance. Furthermore, the inner diameter D2 on the inner surface side of the discharge hole 4 is preferably 200 μm or less, more preferably 150 μm or less. This allows the shape and / or strength of the protrusions to be maintained. For these reasons, the inner diameter D2 on the inner surface side of the discharge hole 4 is preferably 10 μm or more and 200 μm or less, more preferably 50 μm or more and 150 μm or less.

[0037] When the shape when viewed facing the discharge hole 4 is elliptical, the ratio of the minor axis to the major axis (minor axis / major axis) is preferably within the above-mentioned range. The diameter of the ellipse is the equivalent diameter converted into the diameter of a perfect circle with the same cross-sectional area. The diameters of the ellipse are defined as the inner diameter D1 on the outer surface side of the discharge hole 4 and the inner diameter D2 on the inner surface side of the discharge hole 4.

[0038] The ratio (D1 / D2) of the inner diameter D1 on the outer surface side of the discharge hole 4 to the inner diameter D2 on the inner surface side is preferably 1 or more. This reduces the discharge speed of the liquid material L through the discharge hole 4, making it easier to retain the liquid material L around the discharge hole. Furthermore, from the viewpoint of stably discharging the liquid material L, the ratio (D1 / D2) is preferably 10 or less, and more preferably 5 or less. From the above, the ratio (D1 / D2) is preferably 1 or more and 10 or less, and more preferably 1 or more and 5 or less. From the viewpoint of more stably discharging the liquid material L through the discharge hole 4 of the first projection 31, it is preferable that the inner diameter of the discharge hole 4 gradually increases from the inner surface side toward the outer surface side of the first projection 31.

[0039] In the cosmetic tool 1, the ratio of the number of second projections 32 to the number of first projections 31 (number of second projections 32 / number of first projections 31) is preferably 0.05 or more, more preferably 0.1 or more, and even more preferably 0.3 or more. This further improves the permeability of the liquid material L and enhances the blood flow promoting effect. Furthermore, the ratio (number of second projections 32 / number of first projections 31) is preferably 5 or less, more preferably 3 or less, and even more preferably 2 or more. This further improves the permeability of the liquid material L and makes it less likely to damage the stratum corneum. For these reasons, the ratio (number of second projections 32 / number of first projections 31) is preferably 0.05 or more and 5 or less, more preferably 0.1 or more and 3 or less, and even more preferably 0.3 or more and 2 or less.

[0040] The number of first protrusions 31 is preferably 5 or more, more preferably 10 or more, and even more preferably 20 or more. This allows a wide area to be stimulated at once. The number of first protrusions 31 is preferably 200 or less, more preferably 100 or less, and even more preferably 50 or less. This allows the desired location to be stimulated accurately, and also allows appropriate stimulation even in uneven areas such as the face. For the above reasons, the number of first protrusions 31 is preferably 5 to 200, more preferably 10 to 100, and even more preferably 20 to 50.

[0041] The number of second protrusions 32 is preferably one or more, more preferably five or more, and even more preferably ten or more. This allows a wide area to be stimulated at once. The number of second protrusions 32 is preferably 100 or less, more preferably 50 or less, and even more preferably 30 or less. This allows the desired location to be stimulated accurately, and also allows appropriate stimulation even in uneven areas such as the face. For the above reasons, the number of second protrusions 32 is preferably one to 100, more preferably five to 50, and even more preferably ten to 30.

[0042] In the beauty tool 1 of the present invention, it is preferable that two or three or more first protrusions 31 are arranged around one second protrusion 32. It is preferable that these first protrusions 31 are spaced the same distance from the second protrusion 32. More specifically, it is preferable that four or more first protrusions 31 are arranged around one second protrusion 32. It is also preferable that a pair of first protrusions 31, 31 are arranged so as to sandwich the second protrusion 32 in the first direction X, and that a pair of first protrusions 31, 31 are arranged so as to sandwich the second protrusion 32 in the second direction Y perpendicular to the first direction X. An example of this is shown in FIG. 11 .

[0043] The thickness T of the sheet base 7 is preferably 100 μm or more, more preferably 200 μm or more. This makes it easier to grip the cosmetic tool 1 with fingers or the like, and makes the cosmetic tool 1 easier to use. Furthermore, the thickness T is preferably 3,000 μm or less, more preferably 2,000 μm or less. This makes it easier to press the cosmetic tool 1 against the skin. For these reasons, the thickness T is preferably 100 μm or more and 3,000 μm or less, more preferably 200 μm or more and 2,000 μm or less.

[0044] Next, the constituent materials of the beauty tool 1 will be described. From the viewpoint of improving the handleability and processability of the material, the beauty tool 1 preferably contains a thermoplastic resin. More preferably, the beauty tool 1 is formed from a substrate sheet containing a thermoplastic resin. The thermoplastic resin may include one or more selected from the group consisting of polyolefin, polyester, polyamide, polyamideimide, polyetheretherketone, polyetherimide, polycarbonate, polyvinyl chloride, acrylic resin, polystyrene resin, etc. The polyolefin may include one or more selected from polypropylene and / or polyethylene, etc. The polyester may include one or more selected from the group consisting of polyethylene terephthalate, polyfatty acid ester, polylactic acid, polycaprolactone, polybutylene succinate, etc. The polyamide may include Nylon (registered trademark), etc. From the viewpoint of biodegradability, it is preferable to include a polyfatty acid ester. The polyfatty acid ester may include polylactic acid and / or polyglycolic acid.

[0045] From the viewpoint of further improving the moldability and dimensional stability of the protrusions 3, the mass ratio of the thermoplastic resin contained in the cosmetic tool 1 to the total mass of the cosmetic tool 1 is preferably 50% or more, more preferably 70% or more. Alternatively, this mass ratio may be 100%. From the viewpoint of imparting various effects to the cosmetic tool 1 by adding, for example, functional agents, this mass ratio is preferably less than 100%, more preferably 97% or less. Here, various functional agents that can be used include antibacterial agents, disinfectants, moisturizers, flow-improving agents, antistatic agents, colorants, etc.

[0046] The beauty tool 1 of the present invention is not limited to the embodiment shown in Figures 1 to 6. Another embodiment of the beauty tool 1 according to the present invention will be described below. In the following, the other embodiment will be described mainly focusing on the components that differ from the embodiment shown in Figures 1 to 6, and similar components will be given the same reference numerals and will not be described again. For components that are not specifically described, the description of the embodiment shown in Figures 1 to 6 will be applied as appropriate.

[0047] The cosmetic tool 1a of the present invention may have a discharge hole 4 in the first protrusion 31. An example of this is shown in FIG. 7 . Providing the discharge hole 4 in the first protrusion 31 has the advantage of discharging the liquid material L at a position close to the human body surface S, making it easier to deliver the liquid material L to the human body surface S. Another advantage is that the strength of the protrusion 3 can be ensured even when the opening is enlarged to discharge a highly viscous liquid material L. While the discharge hole 4 of the protrusion 3 shown in FIG. 7 is provided at the tip of the first protrusion 31, it may also be provided on the side of the first protrusion 31. Providing the discharge hole 4 on the side of the first protrusion 31 has the advantage of preventing the opening from being blocked by the human body surface S when the cosmetic tool 1 is tapped on the human body surface S, thereby enabling continuous discharge of the liquid material L. The cosmetic tool 1b of the present invention may have all of the protrusions 3 with approximately the same height. An example of this is shown in FIG. 8 .

[0048] In the beauty tool 1 of the above-described embodiment, the discharge holes 4 are formed in the protrusions 3, but the present invention is not limited to this. In a beauty tool 1c of the present invention, the discharge holes 4 may be formed in the sheet base 7. An example of this is shown in Figure 9. In a beauty tool 1d of the present invention, the protrusions 3 may all have approximately the same height and the discharge holes 4 may be formed in the sheet base 7. An example of this is shown in Figure 10.

[0049] In the above-described embodiment, the protrusions 3 have both sides 3a, 3b that are straight when viewed in a cross section normal to the base surface 2. However, this is not limited to this. The protrusions 3 may have both sides 3a, 3b that are non-straight when viewed in a cross section normal to the base surface 2. An example of a beauty tool 1e having such protrusions 3 is shown in Fig. 3(c) and Fig. 11.

[0050] In the cosmetic tool 1e, in a cross-sectional view taken along the normal to the base surface 2, the first protrusion 31e, whose both side edges 3a, 3b are non-linear, preferably has the following shape: First, when the first protrusion 31e is bisected in the height direction Z, the first protrusion 31e has a bulging portion 35 that curves gently outward toward the tip side from the bisecting point. Next, the first protrusion 31e has a constricted portion 38 that curves inward in a convex shape toward the tip side or the base surface 2 side from the bisecting point. The bulging portion 35 preferably has an intermediate narrowing portion 36 and an upper narrowing portion 37. The intermediate narrowing portion 36 is a portion where the radial length of the first protrusion 31e gradually decreases from the maximum diameter portion 34 toward the base surface 2. The upper narrowing portion 37 is a portion where the radial length of the protrusion 31e gradually decreases from the maximum diameter portion 34 toward the upper side. In the upper region of the first protrusion 31e, the tip of the bulging portion 35 preferably forms a maximum diameter portion 34, which is the maximum radial length of the protrusion 3. The constricted portion 38 is preferably located closer to the base surface 2 than the bulging portion 35. The constricted portion 38 is a portion whose radial length is shorter than the portions located above and below in the height direction Z, and is a portion where both side edges of the first protrusion 31e are constricted radially inward. The constricted portion 38 has a minimum diameter portion 39, where the radial length of the first protrusion 31e is minimum. Preferably, a downward diameter enlargement portion 40, whose radial length gradually increases, is provided below the minimum diameter portion 39. An example of this is shown in FIG. 12.

[0051] The protrusions 3 formed on the cosmetic tool 1e may have the same or different opening directions of the discharge holes 4, but it is preferable that they have the same opening direction. For example, the opening directions of the discharge holes 4 of all the protrusions 3 may be oriented in the same direction. This has the advantage that when tapping while moving in the opening direction, a sufficient amount of liquid L is easily discharged at the tapping position, making it easier to achieve a good tapping effect. An example of this is shown in Figure 11. The opening directions of the discharge holes 4 may also be changed alternately or at intervals of several holes.

[0052] When the protrusions 3 have first protrusions 31e and second protrusions 32, from the viewpoint of making the stratum corneum less susceptible to damage by the protrusions 3, it is preferable that the tip diameter WA of the first protrusions 31e be within the range of the tip diameter WA of the protrusions 3 described above.

[0053] When the protrusions 3 include protrusions having bulging portions and constricted portions, the protrusions 3 may all have approximately the same height, an example of which is shown in FIG.

[0054] Next, a beauty method using the beauty tool of the present invention will be described using the beauty tool 1 of the above-described embodiment as an example. In the beauty method using the beauty tool of the present invention, it is preferable to supply a liquid material L to a human body surface S and tap the human body surface S with the liquid material L supplied thereto with the beauty tool 1. The method of supplying the liquid material L to the human body surface S is not particularly limited. For example, the liquid material L may be supplied to the human body surface S by ejecting it from the ejection hole 4, or it may be supplied to the human body surface S by ejecting it using a spray, for example. The state in which the liquid material L has been supplied to the human body surface S is typically a state in which the liquid material L has been applied to the human body surface S. The method of tapping the human body surface S with the beauty tool 1 is not particularly limited, but from the viewpoint of reliably promoting blood flow, it is preferable to press the beauty tool 1 against the skin multiple times. Here, "multiple times" means two or three or more times. An example of a method for tapping the human body surface S multiple times with the cosmetic tool 1 is to lightly tap the surface multiple times with the cosmetic tool 1. Tapping also includes a method in which the cosmetic tool 1 is attached to the roller 6a of a roller-type auxiliary tool 6 (described later) and the roller 6a is rolled over the skin, thereby lightly pressing the cosmetic tool 1 against the skin.

[0055] After extensive research, the inventors discovered that using the liquid material L in combination with the cosmetic tool 1 having the above-described characteristics can more effectively promote blood flow. More specifically, when the cosmetic tool 1 is tapped on a body surface S to which the liquid material L has been applied (see FIG. 15( a)), the body surface S can be pulled up along with the liquid material L when the cosmetic tool 1 is moved away from the body surface S (see FIG. 15( b)). This increases the movement of the body surface S, effectively promoting blood flow. Furthermore, by tapping the body surface S to which the liquid material L has been applied with the cosmetic tool 1, the liquid material L can be efficiently absorbed into the body surface S, thereby promoting blood flow more effectively. This achieves a synergistic effect between the blood flow promotion effect achieved by tapping the body surface S with the cosmetic tool 1 and the blood flow promotion effect of the liquid material L. This enables more effective blood flow promotion than the blood flow promotion effect achieved by simply pressing the cosmetic tool against the skin, as in conventional technology. Furthermore, by tapping the cosmetic tool 1 with the liquid substance L applied to the human body surface S, excessive irritation can be suppressed, and a moderate irritation can be imparted.

[0056] In addition to these effects, the beauty tool 1 having the first protrusions 31 and the second protrusions 32 of different heights has the following effect: With one tapping, different stimuli can be applied at short time intervals, which can promote blood flow more effectively.

[0057] The cosmetic method of the present invention is a method of using a cosmetic tool to promote blood flow. Promotion of blood flow is preferably achieved by tapping the skin. That is, the cosmetic method of the present invention is a method of using the cosmetic tool 1 for cosmetic purposes. The cosmetic use method does not include methods of surgery, treatment, or diagnosis on humans. Examples of cosmetic effects obtained by the cosmetic method of the present invention include skin whitening, improvement of skin blemishes, improvement of dullness or dark circles, improvement of skin wrinkles, improvement of skin sagging, and / or promotion of skin turnover at the site tapped with the cosmetic tool 1. Furthermore, the cosmetic method using the cosmetic tool of the present invention is preferably a method of promoting blood flow at the site tapped with the cosmetic tool 1, thereby producing the above-mentioned cosmetic effects at the site.

[0058] The liquid material L used in the present invention may include a viscous liquid. The viscous liquid may include one or more selected from the group consisting of a lotion, an emulsion, and a beauty serum.

[0059] From the viewpoint of further exerting the blood flow promoting effect, the viscosity of the liquid material L used in the present invention is preferably 1 mPa·s or more, more preferably 1,000 mPa·s or more. From the viewpoint of further improving the ejection property, the viscosity of the liquid material L is preferably less than 5,000 mPa·s, more preferably 4,000 mPa·s or less. From the above viewpoints, the viscosity of the liquid material L used in the present invention is preferably 1 mPa·s or more but less than 5,000 mPa·s, more preferably 1,000 mPa·s or more but 4,000 mPa·s or less. The viscosity of the liquid material L described above is a value measured at 25°C using a B-type viscometer (TVB-10 type viscometer, manufactured by Toki Sangyo Co., Ltd.). The measurement conditions in this case are rotor No. 1 and a rotation speed of 60 rpm.

[0060] In the cosmetic method of the present invention, as described above, it is preferable to perform tapping by pressing the cosmetic tool 1 against the skin multiple times. It is more preferable to perform tapping while continuously or discontinuously supplying the liquid material L. This allows the liquid material L to be supplied more sufficiently to the human body surface S, thereby more effectively promoting blood flow. Examples of means for continuously supplying the liquid material L include commonly used discharge containers such as pump containers, squeeze containers, tube containers, and aerosol containers. Examples of means for discontinuously supplying the liquid material L include jet dispensers and sprayers.

[0061] In the cosmetic method of the present invention, it is preferable to use a manual liquid supply device. It is preferable to use this to perform tapping multiple times while supplying the liquid L between the human body surface S and the cosmetic tool 1. By using such tapping, it is possible to tap while supplying the liquid L to any desired location on the human body surface S. Examples of manual liquid supply devices include a pump container, a squeeze container, and a tube container.

[0062] In the cosmetic method of the present invention, when tapping the skin with the cosmetic tool 1, it is preferable to apply a pressure that does not damage the stratum corneum. Specifically, the pressure when tapping the human body surface S with the cosmetic tool 1 is preferably 100 N / cm ２ or less, more preferably 75 N / cm ２ More preferably 50 N / cm or less ２ This makes it possible to further suppress damage to the stratum corneum.

[0063] It is preferable to cause a flare reaction in the skin by tapping the human body surface S with the cosmetic tool 1. Specifically, the pressure of tapping the human body surface S with the cosmetic tool 1 is preferably 0.01 N / cm ２ More preferably, 0.05 N / cm ２ More preferably, 0.1 N / cm ２ This makes it possible to reliably achieve the blood flow promoting effect.

[0064] In the cosmetic method of the present invention, tapping is preferably performed at a frequency of 0.1 times per second or more, more preferably 0.5 times per second or more. This ensures a blood flow promoting effect and provides the user with a more comfortable feel. From the viewpoint of suppressing damage to the human body surface S, tapping is preferably performed at a frequency of 20 times per second or less, more preferably 10 times per second or less.

[0065] In the cosmetic method of the present invention, tapping is preferably performed for 1 second or more, more preferably 5 seconds or more, from the viewpoint of more reliably achieving the blood flow promoting effect. Furthermore, tapping is preferably performed for 600 seconds or less, more preferably 450 seconds or less, from the viewpoint of more effectively suppressing damage to the stratum corneum. The tapping time refers to the time during which tapping is actually performed. In other words, the tapping time does not refer to the time during which the cosmetic tool 1 is kept pressed against the skin, but rather refers to the time during which the cosmetic tool 1 is repeatedly pressed against and released from the skin. For example, if tapping is performed for 10 seconds, interrupted for 40 seconds, and then tapped again for 10 seconds, the tapping time is 20 seconds.

[0066] A preferred embodiment of a beauty method using the beauty tool of the present invention will be described with reference to Figures 16 to 22, taking the use of beauty tool 1 as an example. For ease of explanation, the size of protrusions 3 is greatly exaggerated in Figures 16 to 22.

[0067] The cosmetic tool used in the present invention preferably has a fixing portion for fixing to a user's finger. An example of a cosmetic tool having a fixing portion for fixing to a user's finger (hereinafter also referred to as "cosmetic tool 1A") will be described. In this case, a liquid material L is typically dispensed onto a human body surface S by a spray or the like. The cosmetic tool 1A preferably has an adhesive 4a on the surface of the base 2 opposite to the surface on which the protrusions 3 protrude, and the adhesive 4a serves as the fixing portion. The surface of the adhesive 4a opposite to the base 2 may be covered with a release sheet made of film, nonwoven fabric, paper, or the like before use of the cosmetic tool 1A. This example is shown in Figures 16 and 17.

[0068] If the surface of the adhesive 4a opposite the base surface 2 is covered with a release sheet, the release sheet is peeled off to expose the surface of the adhesive 4a opposite the base surface 2. Then, as shown in FIG. 17 , the cosmetic tool 1A is fixed with the surface opposite the surface from which the protrusions 3 protrude facing the user's finger. Specifically, the cosmetic tool 1A is attached to the user's finger via the adhesive 4a. Then, the liquid material L is applied to the skin, for example, by spraying, and the skin with the applied liquid material L is tapped with the cosmetic tool 1A. According to the method of use of this embodiment, the skin can be tapped with the cosmetic tool 1A fixed to the finger, making it easy to tap any desired location with the cosmetic tool 1A. Furthermore, the pressure, number of times, etc., used when tapping the cosmetic tool 1A can be adjusted as desired to suit preferences and desired effects.

[0069] As another example, the cosmetic tool 1B may have a notch 2s on the periphery of the area of ​​the base surface 2 where the protrusions 3 protrude, and the notch 2s may serve as a fixing portion. By inserting a finger or the like into the notch 2s, the cosmetic tool 1B can be fixed in place with the surface opposite to the surface where the protrusions 3 protrude facing the user's finger. This example is shown in Fig. 18(a). In this case, the liquid material L is typically supplied to the human body surface S by ejecting it with a spray or the like.

[0070] As another example, the beauty tool 1B may have a sheet base 7 forming a main body 5 having a cylindrical shape with one end closed. The main body 5 is hollow, allowing a finger or the like to be inserted into the main body 5. This beauty tool 1B typically has a finger cot-like shape. In this beauty tool 1B, the main body 5 serves as a fixing part. By inserting a finger or the like into the main body 5, the beauty tool 1B can be fixed in a state where the surface opposite to the surface from which the protrusions 3 protrude faces the user's finger. This example is shown in Figure 18(b).

[0071] The beauty tool used in the present invention is preferably fixed to a tapping aid. Hereinafter, a beauty tool fixed to a tapping aid is also referred to as a "beauty tool 1C." The tapping aid is an aid that facilitates repeated tapping by lightly pressing and rubbing the beauty tool 1C against the skin. That is, the tapping aid is an aid that assists tapping. In this case, the liquid material L is typically dispensed onto the human body surface S using a spray or the like. A roller-type aid 6 is preferably used as an example of a tapping aid. The tapping aid preferably includes a rotatable roller 6a, as in the roller-type aid 6. This makes repeated tapping easier. The roller-type aid 6 preferably includes a rotatable roller 6a and a grip 6b that rotatably supports the roller 6a. It is more preferable that the grip 6b be able to be held and operated with one hand. An example of this is shown in FIG. 19. The roller-type aid 6 includes a grip 6b that rotatably supports the roller 6a, making repeated tapping easier. Furthermore, the gripping portion 6b of the roller-type auxiliary tool 6 to which the cosmetic tool 1C is fixed can be held with one hand, and the cosmetic tool 1C can be lightly pressed against the skin to which the liquid material L has been applied. This allows easy tapping over a wide area of ​​the skin, and also makes it easy to press the cosmetic tool 1C against any desired location.

[0072] The beauty tool 1C may be attached to the roller 6a with the side opposite to the side on which the protrusions 3 protrude facing the surface of the roller 6a, or may be fixed in a non-detachable manner. A method for attaching the beauty tool 1C to the circumferential surface of the roller 6a includes providing an adhesive 4a on the side of the beauty tool 1C opposite to the side on which the protrusions 3 protrude or on the circumferential surface of the roller 6a. Another method includes fixing the beauty tool 1C attached to the circumferential surface of the roller 6a with pins or the like. The beauty tool 1C preferably has an adhesive 4a on the side opposite to the side on which the protrusions 3 protrude, as a fixing portion for fixing the beauty tool 1C to the tapping aid. The adhesive layer on the circumferential surface of the beauty tool 1C or the roller 6a is preferably covered and protected with a release sheet. The release sheet is preferably peeled off when fixing the beauty tool 1C to the roller 6a.

[0073] The roller-type auxiliary tool 6 may include a roller with a polygonal cross section instead of the roller 6a with a circular cross section. The roller-type auxiliary tool 6 may also have no gripping portion 6b, and the roller 6a may be used by rolling it alone over the skin. The roller with a polygonal cross section may have a cross section that is triangular, quadrangular, pentagonal to octagonal, or nonagonal or more. A single continuous beauty tool 1C may be wrapped around the multiple faces that make up the circumferential surface of the roller with a polygonal cross section, or a separate beauty tool 1C may be fixed to each of the multiple faces. The axial direction of the roller 6a and the axial direction of the gripping portion 6b may coincide (see FIG. 19 ) or intersect (see FIG. 20 ).

[0074] The cosmetic tool used in the present invention is preferably fixed to a liquid supplying device. Hereinafter, a cosmetic tool fixed to a liquid supplying device is also referred to as a "cosmetic tool 1D." The liquid supplying device is capable of discharging the liquid L filled therein through the discharge hole 4 while connected to the cosmetic tool 1D. The cosmetic tool 1D and the liquid supplying device may be connected to each other when in use. Alternatively, they may be connected before use and separable after use. Furthermore, they may be inseparably integrated. The liquid L may be pre-filled in the liquid supplying device, or transferred from any container such as an ampoule or small bottle to the liquid supplying device when in use. A syringe 20 (see FIG. 21) or a tube container 21 (see FIG. 22) may be used as the liquid supplying device.

[0075] When using the cosmetic tool 1D with the syringe 20 as the liquid supply device, the index finger and middle finger are typically placed on the finger rest 26. At the same time, the thumb is pressed against the pressing portion 33 of the plunger member 28. Then, the user taps the human body surface S while supplying the liquid material L. According to the method of using the cosmetic tool 1D, tapping can be performed while supplying the liquid material L to the human body surface S, making it easy to tap any desired location. A liquid delivery device, such as a manual or electric liquid delivery pump, may be connected to the cosmetic tool according to the present invention. The liquid material L is delivered to the cosmetic tool by the liquid delivery device. Then, tapping can be performed while the liquid material L is extruded from the discharge hole of the cosmetic tool. In this case, tapping can be performed while supplying the liquid material L to the human body surface S, making it easy to tap any desired location.

[0076] When using the cosmetic tool 1D with the syringe 20 as the liquid supply device, the tube container 21 is held by hand and pressed, and the liquid L is supplied to the human body surface S while tapping. Even in this case, tapping can be performed while supplying the liquid L to the human body surface S, so that tapping can be easily performed on any desired location.

[0077] The present invention encompasses a beauty kit including a beauty tool, a liquid supply device filled with a liquid, and the liquid. The beauty tool included in the beauty kit of the present invention can be the beauty tool 1 of the present invention described above. The liquid supply device can be the liquid supply device of the present invention described above. The liquid material can be the liquid material L of the present invention described above. The liquid supply device is preferably filled with one or more liquid materials selected from a cosmetic liquid, an emulsion, and a beauty serum. According to the kit of the present invention, blood flow can be more effectively promoted by tapping the human body surface S to which the liquid material has been applied with a beauty tool having a specific shape included in the kit.

[0078] While the present invention has been described above based on preferred embodiments thereof, the present invention is not limited to these embodiments and can be modified as appropriate. The preferred configurations of the cosmetic tool described above may be combined. For example, the discharge holes 4 may be formed in both the second projections 32 and the sheet base 7.

[0079] The discharge holes 4 may be formed in both the first projections 31 and the second projections 32 .

[0080] The present invention will be explained in more detail below with reference to examples, but the present invention is not limited to these examples.

[0081] Examples 1 and 2: Cosmetic tools with the same configuration as the cosmetic tools shown in Figures 4(b) and 6(a) were manufactured. The dimensions of the first protrusions, the dimensions of the second protrusions, the position of the discharge holes, and the arrangement of the protrusions in the cosmetic tools used in Examples 1 and 2 are as shown in Table 1. The first protrusions did not have discharge holes. The second protrusions had discharge holes on their side surfaces, and the inner diameter D1 of the discharge hole's discharge outlet and the inner diameter D2 of the discharge inlet were as shown in Table 1. The center position of the discharge inlet was 0.61 mm above the base surface, where the height of the base surface was 0 and the height of the first protrusion was 1. The base sheet contained 100% by mass of polylactic acid, a thermoplastic resin, relative to the total mass of the cosmetic tool.
