[0011] The present invention will be described below based on preferred embodiments thereof. First, the beauty tool of the present invention (hereinafter also referred to as "beauty tool 1") will be described with reference to a preferred embodiment. 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 includes 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 a 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 beauty tool used in the beauty method using the beauty tool of the present invention is preferably 10 μm or more, more preferably 50 μm or more, which makes it possible to prevent damage to the stratum corneum by the protrusions 3 when the beauty tool 1 is tapped on the human body surface S, to prevent excessive irritation, and to improve the effect of lifting the human body surface S together with the liquid material L. 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, which allows for promoting blood flow to the skin with a smaller pressing force and providing a pleasant stimulating sensation. From the above, 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 weaken the tapping pressure from the viewpoint of non-invasiveness. To ensure non-invasiveness regardless of the strength of the force or the method of tapping, it is preferable that the tip diameter WA of the protrusions 3 is relatively large and not extremely sharp. From this perspective, 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 protrusion 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, so that when the cosmetic tool 1 is tapped on the human body surface S, the protrusions 3 are less likely to damage the stratum corneum. The height H of the projections 3 is greater than 0 μm, preferably 50 μm or greater, more preferably 100 μm or greater, and even more preferably 200 μm or greater, thereby efficiently promoting blood flow and efficiently applying the liquid material L to the human body surface S. From the above, the height H of the protrusions 3 is preferably more than 0 μm and not more than 3,000 μm, more preferably 50 μm or more and not more than 2,500 μm, even more preferably 100 μm or more and not more than 2,000 μm, and even more preferably 200 μm or more and not more than 2,000 μm. The degree of the blood flow promoting effect can be determined by various known methods, for example, by determining whether or not a flare reaction occurs in the skin, or by visualizing the blood flow distribution using a laser suction flow meter (LSFG). The projections 3 preferably have tips with a convex curved surface, from the viewpoint of preventing damage to the skin.
[0015] The tip diameter WA of the projection 3 can be measured by the following measurement method. <Measuring method for tip diameter WA of protrusion 3> First, we will explain the case where both side edges 3a, 3b of the protrusions 3 rising from the base surface 2 are straight. 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, the point on the tip side where one side edge 3a deviates from the imaginary straight line ILa is determined as a first tip point 3a1, and the point on the other side edge 3b where 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. This measurement is performed on three protrusions 3 randomly selected from the base surface 2, and the average value of the measurements is taken as the tip diameter WA of the protrusions 3.
[0016] Next, we will explain the case where 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 where 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 projections 3 having discharge ports 42, the discharge holes 4 are through-holes that penetrate the sheet base 7 and the projections 3 in the thickness direction of the sheet base 7 and the projections 3. The hollow portions 30 of the projections 3 function as passages for the liquid material L that is discharged to the outside from the discharge ports 42. The center positions of the discharge ports 42 on the side surfaces of the projections 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 projections 3 is 1, the area of the predetermined height 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 a square, an ellipse, or the like. From the viewpoint of uniformity of the discharge pressure at the discharge holes 4, it is preferable that the shape of the discharge holes 4 when viewed from the opposite side to the discharge holes 4 is circular. From the viewpoint of making it possible to increase the hole diameter and to easily discharge the highly viscous liquid material L, it is preferable that the shape of the discharge hole 4 when viewed opposite the discharge hole 4 is elliptical. When the shape of the discharge hole 4 when viewed opposite the discharge hole 4 is elliptical, the ratio of the minor axis to the major axis (minor axis / major axis) is preferably more than 0 and less than 1, and 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 port 42 is preferably 10 μm or more, and 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 projections, the inner diameter D2 of the discharge inlet 42 of 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, having the tip diameter WA of the protrusions 3 within the above-mentioned range, is capable of non-invasively tapping the human body surface S. The cosmetic tool 1 of the present invention is preferably used for non-invasively tapping the human body surface S. The human body surface S generally has, from the surface side to the inside, the epidermis, including the stratum corneum, and the dermis. 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. When the cosmetic tool 1 has a discharge hole 4, the liquid material L can be discharged from the discharge 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, thereby effectively promoting blood flow. In this way, the cosmetic tool 1 of the present invention can effectively promote blood flow while suppressing damage to the human body surface S and providing a moderate stimulating sensation.
[0021] The base surface 2 has a first direction X and a second direction Y perpendicular to the first direction X in plan view (see FIG. 1). The base surface 2 typically has a plurality of protrusions 3 arranged in a dispersed state in 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 that the number of protrusions 3 is two or three or more. The base surface 2 typically has a protrusion row 3L in which a plurality of protrusions 3 are arranged at intervals along the second direction Y. The protrusion rows 3L are typically provided in a plurality of rows spaced apart in the first direction X. The positions of the protrusions 3 constituting the protrusion rows 3L adjacent to each other in the first direction X may be aligned in the second direction Y (see FIGS. 1 and 6(a)). Here, "multiple protrusion rows 3L" means that there are 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 above-mentioned protrusion rows 3L are arranged. The contour shape of the protrusion arrangement region 3R in plan view can be any shape, such as a circle, an ellipse, a rectangle, a hexagon, a substantially square shape with rounded corners, etc. The contour shape of the protrusion arrangement region 3R is the contour shape of an area 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 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. Typically, in a plan view, the base surface 2 has a non-protrusion arrangement area surrounding the protrusion arrangement area 3R, which makes it difficult for pressure to be dispersed when tapping the human body surface with the cosmetic tool 1, and makes it easier to achieve the blood flow promoting effect with a small force. In order to ensure the above-mentioned effects, when the cosmetic tool 1 is viewed from above, the unit area (1 cm ) of the projection arrangement region 3R is 2 It is preferable that the number N of protrusions 3 per unit area (hereinafter also referred to as "the number N of protrusions 3") is within the range shown below. From the viewpoint of easily achieving 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 2 The following is the result. From the viewpoint of preventing damage to the stratum corneum, the number N of the protrusions 3 is preferably 10 / cm 2 More than 50 / cm 2 That's all. The number N of the protrusions 3 can be calculated by the following method.
[0024] <How to calculate the number N of protrusions 3> When the cosmetic tool 1 is viewed from above, the total area (cm ) of the projection arrangement region 3R in which the projections 3 are arranged in a dispersed manner in the planar direction is 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 number of protrusions by the area of the protrusion arrangement region 3R.
[0025] In order to facilitate accurate stimulation of the intended location with the protrusions 3, when the beauty tool 1 is viewed in a plan view, the area ratio of the protrusion arrangement region 3R to the base surface 2 is preferably 20% or more, and more preferably 30% or more. From the viewpoint of more easily obtaining the blood flow promoting effect with a small force, the area ratio is preferably 80% or less, and 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 allows for accurate stimulation of the desired location, and also makes it possible to appropriately stimulate uneven areas such as the face. From the above, the total number of protrusions 3 is preferably 6 or more and 300 or less, more preferably 15 or more and 150 or less, and even more preferably 30 or more and 80 or less.
[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, and more preferably 0.5 mm or more. This allows the skin to be tapped without being affected by deformation of the skin when adjacent protrusions are pressed against the skin. The distance D is preferably 3 mm or less, and more preferably 2 mm or less, so that the blood flow improving effect caused by adjacent protrusions can be obtained in the application range without any gaps. Assume that the protrusions 3 are adjacent to each other in both the first direction X and the second direction Y, as in the embodiment shown in Fig. 1. The distance between the centers of the protrusions 3 adjacent to each other in the first direction X is defined as Dx, and the distance between the centers of the protrusions 3 adjacent to each other in the second direction Y is defined as Dy. In this case, only one of the distance Dx and the distance 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 be the same in the second direction Y. In this case, typically, the protrusions 3 in the adjacent protrusion rows 3L in the first direction X are out of phase with each other, 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 the protrusion row 3L adjacent to each other in the first direction X do not coincide, 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 the protrusion row 3L adjacent to each other 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 that are taller than the second protrusions 32, and second protrusions 32. When the protrusions 3 have the primary protrusions 31 and the secondary protrusions 32, the tip diameter WA of the primary protrusions 31 is preferably within the above-mentioned range. The tip diameter WA of the secondary projections 32 is preferably 50 μm or more, more preferably 100 μm or more, and even more preferably 150 μm or more, which makes it possible to make the secondary projections 32 less likely to damage the stratum corneum and improve the effect of lifting the human body surface S together with the liquid material L. The tip diameter WA of the secondary projections 32 is preferably 1,000 μm or less, more preferably 700 μm or less, and even more preferably 500 μm or less, which makes it possible to promote blood flow to the skin with a smaller tapping pressure and to provide a pleasant stimulating sensation.
[0031] When the first projections 31 and the second projections 32 are provided, the height H1 of the first projections 31 is preferably within the range of the height H described above. The height H2 of the secondary projections 32 is preferably 10 μm or more, and more preferably 100 μm or more. This makes it possible to efficiently promote blood flow and efficiently apply the liquid material L to the human body surface S. Furthermore, the height H2 of the secondary projections 32 is preferably 2,000 μm or less, and more preferably 1,000 μm or less, which can prevent damage to the stratum corneum by the projections 3 when the cosmetic tool 1 is used to tap the human body surface S. For the above reasons, the height H2 of the secondary projections 32 is preferably 10 μm or more and 2,000 μm or less, and more preferably 100 μm or more and 1,000 μm or less. The ratio (H1 / H2) of the height H1 of the first projections 31 to the height H2 of the second projections 32 is preferably 1 or more, more preferably greater than 1, and even more preferably 1.2 or more. This makes it possible to effectively promote 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, ensuring the discharge of the liquid material L. In addition, the liquid material L can be efficiently applied to the human body surface S. Moreover, the ratio (H1 / H2) is preferably not more than 30, and more preferably not more than 10. 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 supplied to the human body surface S efficiently. From the above, 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 and promoting blood flow when the cosmetic tool 1 is applied to the human body surface S. The ratio WA / H1 is preferably not more than 5, more preferably not more than 1, and even more preferably not more than 0.6, thereby enabling the blood flow promoting effect to be obtained with even simpler operation. From the above, 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 protrusion 3 means the distance along the thickness direction Z of the sheet base 7 from the surface of the base surface 2 on which the protrusion 3 protrudes to the tip of the protrusion 3, and can be measured by the following method. <Method for measuring the height of the protrusion> The base surface 2 is cut to obtain a sheet piece with the cut surface of the protrusions 3 exposed, 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 observation field image. Next, the distance from the base surface 2 to the tip of the protrusion 3 along the thickness direction Z of the sheet base 7 is measured. The distance measured in this way is defined as the height H of the protrusion.
[0034] The protrusions 3 may have 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 that serve as discharge outlets 41 at the tips or side surfaces of the protrusions 32. As an example of this, an example in which the discharge holes 4 are at the tips of the second protrusions 32 is shown in FIG. 4(a), and an example in which the discharge holes 4 are at the side surfaces of the second protrusions 32 is shown in FIG. 4(b). When the cosmetic tool 1 is tapped on the human body surface S, it is preferable to prevent the opening from being blocked by the human body surface S, thereby enabling continuous discharge of the liquid material L. From this viewpoint, it is preferable that the discharge hole 4 of the second projection 32 has a discharge outlet 41 on the side surface of the projection 32. With this configuration of the beauty tool 1, when the human body surface S is tapped with the beauty 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 to the human body surface S from the second protrusions 32 even when the first protrusions 31 are pressed against the skin. When the beauty tool 1 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 primary projection 31 may have a shape including a bulging portion 35 and a constricted portion 38, which will be described later.
[0035] 4(a), (b), and 5, the discharge hole 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 hole 4 is 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. The inner diameter on the outer surface side refers to the inner diameter of the discharge outlet 41, and the inner diameter on the inner surface side 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 side of the discharge holes 4 is preferably 10 μm or more, and more preferably 20 μm or more. In addition, from the viewpoint of maintaining the strength of the projections 3, the inner diameter D1 of the outer surface side of the discharge holes 4 is preferably 600 μm or less, and 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, and 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. The inner diameter D2 of the inner surface of the discharge hole 4 is preferably 200 μm or less, and more preferably 150 μm or less, which allows the shape and / or strength of the projections to be maintained. From the above, the inner diameter D2 of the inner surface of the discharge hole 4 is preferably 10 μm or more and 200 μm or less, and 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 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 equal to or greater than 1. 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. Moreover, 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 holes 4 of the primary projections 31, it is preferable that the inner diameter of the discharge holes 4 gradually increases from the inner surface side of the primary projections 31 toward the outer surface side.
[0039] In the cosmetic tool 1, the ratio of the number of secondary projections 32 to the number of primary projections 31 (number of secondary projections 32 / number of primary projections 31) is preferably 0.05 or more, more preferably 0.1 or more, and even more preferably 0.3 or more. This can further improve the permeability of the liquid material L and enhance the blood flow promoting effect. Furthermore, the ratio (number of secondary projections 32 / number of primary projections 31) is preferably not more than 5, more preferably not more than 3, and even more preferably not less than 2. This can further improve the permeability of the liquid L and make it less likely to damage the stratum corneum. From the above, the ratio (number of secondary projections 32 / number of primary 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 primary protrusions 31 is preferably 5 or more, more preferably 10 or more, and even more preferably 20 or more. This makes it possible to stimulate a wide area 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 on uneven areas such as the face. For the above reasons, the number of primary projections 31 is preferably 5 or more and 200 or less, more preferably 10 or more and 100 or less, and even more preferably 20 or more and 50 or less.
[0041] The number of secondary protrusions 32 is preferably 1 or more, more preferably 5 or more, and even more preferably 10 or more. This makes it possible to stimulate a wide area 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 on uneven areas such as the face. For the above reasons, the number of secondary projections 32 is preferably 1 or more and 100 or less, more preferably 5 or more and 50 or less, and even more preferably 10 or more and 30 or less.
[0042] In the beauty tool 1 of the present invention, it is preferable that two or three or more primary projections 31 are arranged around one secondary projection 32. It is preferable that these primary projections 31 are spaced the same distance from the secondary projection 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, and more preferably 200 μm or more, which makes the cosmetic tool 1 easier to grip with fingers etc., and makes the cosmetic tool 1 easier to use. The thickness T is preferably 3,000 μm or less, and more preferably 2,000 μm or less, which makes it easier to press the cosmetic tool 1 against the skin. From the above, the thickness T is preferably 100 μm or more and 3,000 μm or less, and more preferably 200 μm or more and 2,000 μm or less.
[0044] Next, the constituent materials of the cosmetic tool 1 will be described. From the viewpoint of improving the handleability and processability of the material, the cosmetic tool 1 preferably contains a thermoplastic resin, and more preferably is formed from a base 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, and the like. The polyolefin may include one or more selected from polypropylene and / or polyethylene. The polyester may include one or more selected from the group consisting of polyethylene terephthalate, polyfatty acid ester, polylactic acid, polycaprolactone, polybutylene succinate, and the like. Polyamides can include nylon and the like. From the viewpoint of biodegradability, it is preferable that the polyfatty acid ester contains polylactic acid and / or polyglycolic acid.
[0045] To further improve the moldability and dimensional stability of the protrusions 3, the proportion of the mass of the thermoplastic resin contained in the cosmetic tool 1 to the total mass of the cosmetic tool 1 is preferably 50% or more, and more preferably 70% or more. The mass ratio may be 100%. From the viewpoint of imparting various effects to the cosmetic tool 1 by adding, for example, functional agents, the mass ratio is preferably less than 100%, and more preferably 97% or less. Here, various functional agents such as antibacterial agents, disinfectants, moisturizing agents, flow improvers, antistatic agents, and colorants can be used.
[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 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 discharge holes 4 provided in the first projections 31. An example of this is shown in Fig. 7. Providing the discharge holes 4 in the first projections 31 has the advantage that the liquid material L can be discharged 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 projections 3 can be ensured even if the openings are made larger to discharge a highly viscous liquid material L. 7 is provided at the tip of the first projection 31, it may be provided on the side surface of the first projection 31. Providing the discharge hole 4 on the side surface of the first projection 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. In the cosmetic tool 1b of the present invention, all of the protrusions 3 may have approximately the same height, an example of which is shown in FIG.
[0048] In the cosmetic tool 1 of the above-described embodiment, the discharge holes 4 are formed in the projections 3, but the present invention is not limited to this configuration. In the cosmetic 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 FIG. Furthermore, in the beauty tool 1d of the present invention, the height of the projections 3 may all be approximately the same, and the discharge holes 4 may be formed in the sheet base 7. An example of this is shown in FIG.
[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, the first protrusion 31e, whose both side edges 3a, 3b are non-linear, preferably has the following shape in a cross-sectional view taken along the normal to the base surface 2. 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 on the tip side of the bisecting point. Second, the first protrusion 31e has a constricted portion 38 that curves inward in a convex shape on the tip side or base surface 2 side of the bisecting point. The bulging portion 35 preferably has an intermediate width reducing portion 36 and an upper diameter reducing portion 37. The intermediate width reducing portion 36 is a portion where the radial length of the first protrusion 31e gradually reduces from the maximum diameter portion 34 toward the base surface 2. The upper diameter reducing portion 37 is a portion where the radial length of the protrusion 3 gradually reduces from the maximum diameter portion 34 toward the upper side. In the upper region of the first protrusion 31e, it is preferable that the portion where the tip of the bulging portion 35 is located is the maximum diameter portion 34 where the radial length of the protrusion 3 is greatest. 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 projection 31e are constricted radially inward. The constricted portion 38 has a minimum diameter portion 39 where the radial length of the first projection 31e is at its minimum. It is preferable that a downward diameter enlarging 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 ejection holes 4, but it is preferable that they have the same orientation. For example, the ejection holes 4 of all the protrusions 3 may be oriented in the same direction. This has the advantage that tapping while moving in the direction of the ejection holes makes it easier to eject a sufficient amount of liquid material L at the tapping position, making it easier to achieve a good tapping effect. An example of this is shown in Figure 11. Furthermore, the opening direction of the discharge holes 4 may be changed alternately or every several holes.
[0052] When the protrusions 3 have first protrusions 31e and second protrusions 32, 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, in order to prevent the stratum corneum from being damaged by the protrusions 3.
[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 a 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 the liquid material L may be supplied to the human body surface S by ejecting it using a spray or the like. 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. There are no particular limitations on the method of tapping the human body surface S with the cosmetic tool 1, but from the viewpoint of reliably promoting blood flow, it is preferable to press the cosmetic tool 1 against the skin multiple times, where 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 present 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 results in 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 a cosmetic tool against the skin, as in conventional techniques. Furthermore, by tapping the cosmetic tool 1 with the liquid material 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. The 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 method of use for cosmetic purposes does not include methods of surgery, treatment, or diagnosis for humans. The cosmetic effects obtained by the cosmetic method of the present invention include, for example, whitening of the skin at the area where the cosmetic tool 1 is tapped, improvement of skin blemishes, improvement of dullness or dark circles on the skin, improvement of skin wrinkles, improvement of sagging skin, and / or promotion of skin turnover. Furthermore, the beauty method using the beauty tool of the present invention is preferably a method of use that promotes blood flow in the area tapped with the beauty tool 1, thereby producing the above-mentioned beauty effects in the area.
[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 lotion, emulsion, and serum.
[0059] In order to further enhance the blood flow promoting effect, the viscosity of the liquid material L used in the present invention is preferably 1 mPa·s or more, and more preferably 1,000 mPa·s or more. From the viewpoint of further improving the ejection properties, the viscosity of the liquid material L is preferably less than 5,000 mPa·s, and 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 and less than 5,000 mPa·s, and more preferably 1,000 mPa·s or more and 4,000 mPa·s or less. The viscosity of the liquid material L is a value measured at 25° C. using a B-type viscometer (TVB-10 type viscometer manufactured by Toki Sangyo Co., Ltd.) in this case. The measurement conditions 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 a pump container, a squeeze container, a tube container, and an aerosol container. Examples of means for discontinuously supplying the liquid material L include a jet dispenser and a spray.
[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 dispensers include pump containers, squeeze containers, and tube containers.
[0062] In the beauty method of the present invention, when tapping the skin with the beauty 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 beauty tool 1 is preferably 100 N / cm 2 Less than or equal to 75N / cm 2 or less, more preferably 50 N / cm 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, 0.05N / 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, and more preferably 0.5 times per second or more, which ensures a blood flow promoting effect and provides a more comfortable feeling to the user. From the viewpoint of suppressing damage to the human body surface S, it is preferable to perform tapping at a frequency of 20 times or less per second, and more preferably at a frequency of 10 times or less per second.
[0065] In the cosmetic method of the present invention, tapping is preferably performed for 1 second or more, and more preferably for 5 seconds or more, from the viewpoint of more reliably achieving the blood flow promoting effect. From the viewpoint of further suppressing damage to the stratum corneum, tapping is preferably performed for 600 seconds or less, and more preferably for 450 seconds or less. The tapping time refers to the time spent actually tapping. In other words, the tapping time does not refer to the time spent pressing the cosmetic tool 1 against the skin, but rather refers to the time spent repeatedly pressing and releasing the cosmetic tool 1 against the skin. For example, if tapping is performed for 10 seconds, then stopped 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 part for fixing to a user's finger. An example of a cosmetic tool having a fixing part for fixing to a user's finger (hereinafter also referred to as "cosmetic tool 1A") will be described. In this case, the liquid material L is typically supplied to the human body surface S by ejecting the liquid material L using 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 from which the protrusions 3 protrude, and the adhesive 4a serves as a fixing part. 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. Examples of this are 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, peel off the release sheet 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 liquid material L applied 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., 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 Figure 18(a). In this case, the liquid material L is typically supplied to the human body surface S by ejecting it using 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 place with the side opposite to the side with the protrusions 3 facing 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, the beauty tool fixed to the tapping aid is also referred to as "beauty tool 1C." The tapping aid is an aid that makes it easy to repeatedly press and release the beauty tool 1C against the skin. In other words, the tapping aid is an aid that assists tapping. In this case, the liquid material L is typically supplied to the human body surface S by ejecting it using a spray or the like. It is preferable to use a roller-type auxiliary tool 6 as an example of a tapping auxiliary tool. The tapping auxiliary tool preferably has a rotatable roller 6a, like the roller-type auxiliary tool 6. This makes it easier to perform repeated tapping. The roller-type auxiliary tool 6 preferably has a rotatable roller 6a and a gripping part 6b that rotatably supports the roller 6a, and it is more preferable that the gripping part 6b can be held and operated with one hand. An example of this is shown in FIG. 19. The roller-type auxiliary tool 6 includes a gripping portion 6b that rotatably supports the roller 6a, making repeated tapping even easier. Furthermore, the gripping portion 6b of the roller-type auxiliary tool 6 to which the cosmetic tool 1C is fixed can be held in 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 tapping to be performed easily over a wide area of the skin, and the cosmetic tool 1C can also be easily pressed against any desired location.
[0072] The beauty tool 1C may be attachable to the roller 6a with the surface opposite to the surface on which the protrusions 3 protrude facing the surface of the roller 6a, or may be fixed so as not to be detachable. One method for attaching the beauty tool 1C to the circumferential surface of the roller 6a is to provide an adhesive 4a on the surface of the beauty tool 1C opposite to the surface on which the protrusions 3 protrude, or on the circumferential surface of the roller 6a. Another method is to fix the beauty tool 1C attached to the circumferential surface of the roller 6a with a pin or the like. The beauty tool 1C preferably has an adhesive 4a on the surface on the beauty tool 1C opposite to the surface on which the protrusions 3 protrude, as a fixing part for fixing the beauty tool 1C to the tapping aid. The adhesive layer provided on the circumferential surface of the cosmetic tool 1C or the roller 6a is preferably covered and protected with a release sheet, and the release sheet is preferably peeled off when the cosmetic tool 1C is fixed 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, octagonal, or nonagonal or more. A single continuous beauty tool 1C may be wrapped around the multiple surfaces 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 surfaces. The axial direction of the roller 6a and the axial direction of the gripping portion 6b may coincide (see FIG. 19) or may intersect (see FIG. 20).
[0074] The beauty tool used in the present invention is preferably fixed to a liquid supplying device. Hereinafter, the beauty tool used by fixing to the liquid supplying device is also referred to as a "beauty tool 1D." The liquid supplying device is configured to be able to discharge the liquid material L filled in the liquid supplying device from a discharge hole 4 while connected to the beauty tool 1D. The cosmetic tool 1D and the liquid supply device may be connected to each other when in use. Alternatively, they may be connected before use and be separable after use. Furthermore, they may be integrated and inseparable. The liquid L may be pre-filled in the liquid supply device, or transferred from any container such as an ampoule or small bottle to the liquid supply device when in use. As the liquid supply device, a syringe 20 (see FIG. 21) or a tube container 21 (see FIG. 22) may be used.
[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 body surface S while supplying the liquid material L to the body surface S. According to the method of using the cosmetic tool 1D, tapping can be performed while supplying the liquid material L to the body surface S, making it easy to tap any desired location. The cosmetic tool according to the present invention may be connected to a liquid delivery means such as a manual or electric liquid delivery pump. The liquid delivery means delivers the liquid material L to the cosmetic tool. Then, tapping may be performed while the liquid material L is being 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 user taps the human body surface S while supplying the liquid material L. Even 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.
[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 material supply device is preferably filled with one or more liquid materials selected from a cosmetic liquid, an emulsion, and a beauty serum.

The first projections did not have discharge holes. The second projections had discharge holes on their sides, and the inner diameter D1 of the discharge outlet of the discharge holes and the inner diameter D2 of the discharge inlet were as shown in Table 1. The center position of the discharge inlet was at a height of 0.61, where the height of the base surface was 0 and the height of the first projections was 1. The base sheet used was a sheet containing 100% by mass of polylactic acid, a thermoplastic resin, relative to the total mass of the beauty tool. The base sheet was subjected to a protrusion-forming process using a processing needle to which ultrasonic vibrations were applied to form the beauty tool. In Examples 1 and 2, a treatment was performed in which the skin to which the liquid had been applied was tapped with a cosmetic tool. The liquid was continuously supplied during tapping. The tapping pressure was 5.5 N / cm. 2 The tapping time was 60 seconds. The tapping frequency was two times per second. The liquid used was a cosmetic liquid (Kao Corporation, product name: est GP conditioning serum lucent, manufactured in 2024, viscosity 1,500 mPa·s). Example 3 A beauty tool having the same configuration as the beauty tool shown in Figures 9 and 6(a) was manufactured. The first and second protrusions did not have discharge holes. The discharge holes were provided in the sheet base. Other than that, it had the same configuration as Example 1. The method of tapping the skin with the beauty tool was performed while continuously supplying the liquid, as in Example 1.
[0090] Examples 4 and 7 to 11 Cosmetic tools were manufactured in the same manner as in Example 1, except that the cosmetic tool was changed to one having the same configuration as the cosmetic tool shown in Figures 11 and 13. The dimensions of the first projections, the dimensions of the second projections, and the positions of the discharge holes in the cosmetic tools used in Examples 4 and 7 to 11 are as shown in Table 1. The first projections have discharge holes on their sides, and the inner diameter D1 of the discharge outlet and the inner diameter D2 of the discharge inlet of the discharge holes are as shown in Table 1. The method of tapping the skin with the cosmetic tool was performed while continuously supplying the liquid material, as in Example 1.
[0091] Examples 5 and 6 A beauty tool was manufactured in the same manner as in Example 1, except that the beauty tool was changed to one having the same configuration as the beauty tool shown in Figures 14 and 6(a).

[0092] Comparative Example 1 A beauty tool was manufactured in the same manner as in Example 1, except that no secondary projections were provided and the dimensions of the primary projections were changed as shown in Table 1. The method of tapping the skin with the beauty tool was the same as in Example 1, except that no liquid was applied to the skin. Comparative Example 2 In this comparative example, a liquid was applied to the skin, and the following evaluations were carried out one minute after application. No cosmetic tool was used, and no tapping was performed. The liquid used was the same as in Example 1. Comparative Example 3 A beauty tool was manufactured in the same manner as in Example 1, except that the secondary projections were not provided and the dimensions of the primary projections were changed as shown in Table 1. The method of tapping the skin with the beauty tool was performed while continuously supplying a liquid material, as in Example 1.
[0093] [Evaluation of blood flow promoting effect] The blood flow promoting effect of Examples 1 to 11 and Comparative Examples 1 to 3 was evaluated by the following method. The subjects were allowed to acclimate for 20 minutes at a room temperature of approximately 24±1°C and a relative humidity of approximately 50±5%. After that, blood flow on the inner side of the forearm was measured for 12 seconds using a laser speckle blood flowmeter (Omegawave Corporation, product name: OMEGAZONE OZ-2), and the average value was used as the initial blood flow rate. The subjects were one woman in her 30s and one woman in her 40s. The treatments described in Examples 1 to 11 and Comparative Examples 1 to 3 were performed, and measurements were taken every minute from immediately after treatment until 10 minutes later, at 11 points for 12 seconds each. The average value for each of the 11 points was divided by the initial blood flow rate to determine the change in blood flow per minute. The "change in blood flow per minute" for the 11 points was added together to calculate the total change in blood flow over 10 minutes after treatment. Blood flow was evaluated as the average of measurements taken four or more times. The evaluation results are shown in Table 1. [Evaluation of irritation sensation] One woman in her 30s and one woman in her 40s were asked to evaluate the blood flow promoting effect while simultaneously rating the degree of pain (sensation of irritation) on a 10-point scale based on the following criteria. The subjects performed the evaluation three times, and the average values are shown in Table 1. A stimulating sensation score of around 5 to 6 is a comfortable, pleasant stimulating sensation (tingling sensation). 0: Weak stimulation (no pain felt). 10: It hurts so much that it is difficult to continue using it.
[0094] [Table 1]
[0095] [Table 2]
[0096] As is clear from the results shown in Table 1, the beauty tools of Examples 1 to 11 provided a moderate stimulating sensation and also showed excellent results in terms of the blood flow promoting effect, compared to Comparative Examples 1 to 3. Examples 6, 7 and 10 were able to increase the blood flow effect with a pleasant stimulating sensation. Example 8 had the greatest blood flow promotion effect among the examples. The above results demonstrate that the cosmetic tool of the present invention and the method of using the cosmetic tool can effectively promote blood flow while providing a moderate stimulating sensation.
