[0056] Hereinafter, a mode for implementing the present invention will be described with reference to the drawings. In the following drawings, the same components are given the same reference numerals, and repeated descriptions may be omitted sometimes.

[0057] The present invention relates to a cosmetic application tool (such as a mascara tool, etc.) having a coating body (comb body) for applying a liquid such as mascara to eyelashes or hair.

[0058] <First Embodiment>

[0059] First, Figure 2 , the overall structure of the cosmetic applicator according to the first embodiment will be described. Figure 2 is a view showing the overall structure of the cosmetic applicator including the comb body according to the first embodiment of the present invention.

[0060] As Figure 2 shown, the cosmetic applicator 4 includes a comb body (coating comb body) 1 as a coating body, a shaft portion (support shaft) 2, and a grip portion 3.

[0061] The cylindrical grip portion (lid portion) 3 is attached to the shaft portion 2 and is the part held by the user during use. In addition, an internal thread is formed on the inner peripheral surface of the outer cylinder of the grip portion 3, and the grip portion 3 can be threadedly connected to a bottle (container) for containing cosmetics and functions as a lid portion for the bottle. In addition, the shaft portion 2 can be detachable from the grip portion 3 or integrally formed.

[0062] The cosmetic applicator 4 according to the present embodiment is a comb-type mascara in which the comb portion and the shaft portion are integrally formed. That is, the front end of the shaft portion 2 is integrally provided with the comb body 1, which is a coating body for applying mascara liquid or the like around the eyes. The comb body 1 can comb the eyelashes while applying cosmetics such as mascara liquid to the eyelashes.

[0063] Cosmetics such as mascara liquid filled in the bottle are attached to the comb body 1. The cosmetics attached to the comb body 1 are not limited to mascara liquid (mascara), and can also be a hair growth agent for eyelashes, a mascara base, an eyelash coating agent, a coating agent for eyelash extensions, an eyeliner liquid, and multi-purpose cosmetics such as a multi-purpose cosmetic composition for mascara and eyeliner.

[0064] In the cosmetic applicator 4, at least the shaft portion 2 and the comb body 1 are formed by integrally molding a resin. As the resin material, a thermoplastic resin is preferably used, and for example, an elastomer, polyethylene, polypropylene, polystyrene, polyethylene terephthalate, polybutylene terephthalate, polycarbonate, polyacetate, nylon, etc. can be used.

[0065] Next, Figures 2 to 6 , the details of the comb body 1 as a coating body will be described. Figures 3 to 6 is an enlarged view of the comb body 1 according to the first embodiment. Figure 3 is an explanatory view of the comb body according to the first embodiment, Figure 3 (a) is a plan view of the abdominal side, Figure 3 (b) is a front view. Figure 4 is a perspective view of the comb body according to the first embodiment. Figure 5 is a bottom perspective view of the comb body according to the first embodiment. Figure 6Explanatory drawing of the upper surface of the comb body according to the first embodiment.

[0066] As can be seen from Figures 2 to 6 in this embodiment, in the comb body 1, a plurality of protrusions 10 protruding from a pedestal surface (one surface) 18 extending in a specified width along the axial direction A of the shaft portion 2 are arranged on the front end side of the shaft portion 2. The protrusion 10 according to this embodiment is not a flat plate but a bent crank shape.

[0067] The surface on the ventral side where the protrusion 10 is provided in the circumferential direction of the shaft portion 2 in the comb body 1 is defined as the pedestal surface 18. In addition, the surface on the back side other than the pedestal surface 18 of the comb body 1 is defined as the back surface 19.

[0068] On the other hand, on the axial direction A of the shaft portion 2 in the comb body 1, a front end protrusion 16 is provided at the front end of the comb body 1. In addition, a connecting portion 17 for connecting to the shaft portion 2 is provided at the rear end of the comb body 1.

[0069] The plurality of protrusions 10 are symmetrically shaped cranks with the width direction W as the axis of symmetry, and the first protrusion 11 and the second protrusion 12 are alternately arranged in the axial direction A.

[0070] The first protrusion 11 is integrally formed by the first protrusion 13A, the connecting top wall 15A, and the second protrusion 14A. The second protrusion 12 is integrally formed by the first protrusion 13B, the connecting top wall 15B, and the second protrusion 14B.

[0071] In other words, each protrusion 10 (11, 12) of the plurality of protrusions of the comb body 1 has the first protrusion 13A or 13B, the second protrusion 14A or 14B, and the connecting top wall 15A or 15B.

[0072] As shown in Figure 3 (a), the first protrusions 13A, 13B are located on the first side edge E1 side in the width direction of the pedestal surface (one surface) 18, and at the same time protrude from the root extending from the first side edge E1 to the center.

[0073] The second protrusions 14A, 14B are located on the second side edge E2 side opposite to the first side edge E1 in the width direction of the pedestal surface 18, and at the same time protrude from the root extending from the second side edge E2 to the center.

[0074] The connecting top walls 15A, 15B connect the central ends in the width direction W of the first protrusions 13A, 13B and the central ends in the width direction W of the second protrusions 14A, 14B at the center in the width direction W of the pedestal surface 18. As shown in Figure 3 (a), the connecting top walls 15A, 15B are longer in the axial direction A than in the width direction W.

[0075] Here, the positions of the first protrusions 13A and 13B and the second protrusions 14A and 14B are all different in the axial direction A. Therefore, the first protrusion portion 11 according to the present embodiment has a crank shape and bends at two positions, namely, the boundary between the first protrusion 13A and the connecting top wall 15A and the boundary between the connecting top wall 15A and the second protrusion 14A. The second protrusion portion 12 has a crank shape and bends at two positions, namely, the boundary between the first protrusion 13B and the connecting top wall 15B and the boundary between the connecting top wall 15B and the second protrusion 14B. In addition, based on the above structure, the contours of the roots of the respective protrusion portions 11 and 12 of the plurality of protrusion portions 10 include portions that are different in the axial direction A.

[0076] In addition, as Figure 2 , Figure 3 (a), Figure 3 (b) shown, at both ends in the width direction W of the pedestal surface 18 of the comb body 1, that is, on the side edges E1 and E2, the plurality of protrusion portions 10 are arranged in the axial direction A in an alternating manner of wide intervals and narrow intervals.

[0077] Specifically, the plurality of first protrusions 13A and 13B are alternately arranged in the axial direction, separating the first specified interval Ga and the second specified interval Gb that is longer than the first specified interval Ga. In addition, the plurality of second protrusions 14A and 14B are alternately arranged in the axial direction A, separating the second specified interval Gb and the first specified interval Ga.

[0078] As an example, appropriately, the first specified interval Ga is 0.2 to 0.6 mm, more preferably 0.3 to 0.5 mm, and appropriately, the second specified interval Gb is 1.0 to 1.7 mm, more preferably 1.2 to 1.5 mm. Appropriately, in the setting of the above intervals, the second specified interval Gb is 3 to 4 times the first specified interval Ga.

[0079] The first connecting top wall 15A that connects the top walls 15A and 15B connects the central end of the first protrusion 13A on the rear end side in the axial direction A and the central end of the second protrusion 14A on the front end side in the axial direction A in the first protrusion portion 11. On the other hand, the second connecting top wall 15B connects the central end of the first protrusion 13B on the front end side in the axial direction A and the central end of the second protrusion 14B on the rear end side in the axial direction A in the second protrusion portion 12. The first connecting top wall 15A and the second connecting top wall 15B are alternately arranged in the axial direction A.

[0080] In addition, referring to Figure 4 , Figure 5, the first protrusions 13A, 13B and the second protrusions 14A, 14B increase in height toward the center in the width direction W and are flat plates in a substantially right-angled triangle shape. Further, the first protrusions 13A, 13B and the second protrusions 14A, 14B are axially symmetric with the connecting top walls 15A, 15B as the axis of symmetry. Further, among the front protrusions 16 located more forward than the pedestal surface 18, the rear end surface increases in height toward the center in the width direction W, is in a substantially isosceles triangle shape, and has an arc on the front end side. The protruding portions 11, 12 including the crank shape are triangular as a whole in the width direction, whereby the respective protruding portions 11, 12 can be easily brought close to the roots of the eyelashes.

[0081] Refer to Figure 3 (b), the highest parts of the protruding portions 11, 12, that is, the height H from the pedestal surface 18 of the connecting top walls 15A, 15B is 5 to 7 mm. Further, at the front end portion T of the comb body 1 in the axial direction A, the closer to the front end side, the thinner the front and the narrower the area on the back side. However, at the front end portion T, the height of the protruding portions 11, 12 is the same as that of the central portion of the pedestal surface 18, and thus, the diameter is thinner, and the front end portion T for, for example, around the eyes and the corners of the eyes can also arrange the eyelashes in the same manner as the central portion.

[0082] Further, refer to Figure 4 , Figure 6 , the pedestal surface 18 is curved in the width direction in a convex manner in the protruding direction (ventral direction) of the plurality of protruding portions 10. For example, Figure 6 the curvature R of the bending of the pedestal surface 18 shown in (b) is 0.2 to 1.3.

[0083] Here, at the central position in the width direction W of the pedestal surface 18, the first connecting top wall 15A and the second connecting top wall 15B have a specified length in the axial direction A. When the comb body 1 is taken out from the bottle containing the mascara liquid at the angle shown in Figure 4 , the mascara liquid can adhere to the upper sides of the first connecting top wall 15A and the second connecting top wall 15B. Thus, compared with a linear comb body, the amount of the mascara liquid adhered to the comb body 1 of the present embodiment (liquid content) is increased.

[0084] Furthermore, Figure 4 in the example of

[0085] Similarly, when tilting upward on the second side edge E2 side, the top walls 15B, 15B are connected, and the plurality of second protrusions 14A, 14B surround the relatively wide second specified interval Gb. Therefore, the mascara liquid attached to the upper side of the connecting top walls 15A, 15B is supported and does not fall off, and can be transported to the user's eyelashes.

[0086] In addition, the pedestal surface 18 is bent toward the ventral side. Thus, for example, when the comb body 1 is taken out of the bottle at Figure 4 such an angle, the mascara liquid can also adhere to the bent pedestal surface 18. Therefore, compared with the flat comb body, the pedestal surface 18 increases the attachment amount (including liquid) of the mascara liquid of the comb body 1 of the present embodiment.

[0087] Furthermore, when combing the eyelashes with the comb body 1 of the present embodiment, the eyelashes that enter the relatively wide second specified interval Gb surrounded by the crank-shaped protrusions 11, 12 are exposed through the first specified interval Ga that is a narrow space. Therefore, by combing while squeezing the nearby hairs, the tips of the eyelashes are oriented neatly and are separated into bundles with less eyelash volume (separated). Thus, a bunchy feeling appears in the eyelashes, and the impression of the eyelashes becomes stronger.

[0088] In this way, the cosmetic applicator 4 having the comb body 1 according to the present embodiment does not use, for example, a separate finishing metal mascara comb body, such as Figure 1 the bristles on the back side and tweezers like that. It can also organize the eyelashes in the desired direction and create a bunchy feeling in the eyelashes only by performing the minimal action of combing the eyelashes. As a result, the user can reduce the pressure caused by clumping, increase the satisfaction with the state of the eyelashes after applying mascara, and save the time required for makeup.

[0089] (Experimental Example 1)

[0090] Here, the applicants of the present application conducted a questionnaire survey on the completion status after using the comb body 1 according to the first embodiment for 10 female experimenters. Figure 10 It is a graph showing the results of the questionnaire survey on the completion status after using the comb body 1 according to the first embodiment.

[0091] In the present embodiment, the content of the mascara liquid is a black fiber-free mixed mascara. The fiber-free mixed mascara liquid has a tendency to achieve a natural finish compared to the fiber-mixed mascara.

[0092] In this experiment, regarding the comb body 1 of the first embodiment

[0093] (1) In a bottle filled with the content (mascara liquid), an unused comb body 1 is placed, and the cosmetic applicator having the comb body 1 is rotated three times left and right to mix the content liquid well into the comb body.

[0094] (2) Apply the mascara liquid attached to the comb body 1 to the left and right eyelashes 20 times each.

[0095] (3) Evaluate the completion of the eyelashes after application. When evaluating, the experimenter evaluates the completion of their own eyelashes reflected in a table mirror, a washroom mirror, or / and a wall-mounted mirror.

[0096] For the evaluation items, "uniform completion without clumping", "completion with eyelashes evenly separated", "completion with eyelashes lengthened", "completion with eyelashes thickened", "completion with elastic eyelashes", among 10 experimenters, each person can have multiple answers.

[0097] As Figure 7 shown, it can be seen that for the completion of the eyelashes of 10 experimenters using the comb body 1 of this embodiment, the evaluation of "completion with eyelashes evenly separated" is the most.

[0098] (Experimental Example 2)

[0099] The inventors of the present application made a comparison with a comparative example in order to compare the usage conditions of the shape of this embodiment and the shape of the comparative example. Figure 8 It is an explanatory diagram of the comb body (coating body) related to the comparative example used in the experiment. Figure 8 (a) is a perspective view of the comb body related to the comparative example, Figure 8 (b) is a plan view of the abdomen of the comb body.

[0100] The axial length of the pedestal surface 87 of the comb body 8 related to the comparative example is the same as the axial length of the pedestal surface 18 of the first embodiment. The pedestal surface 87 is curved in the width direction in a convex manner in the protruding direction (ventral direction) of the plurality of protrusions 81, and the curvature R of the bending is the same as that of the first embodiment.

[0101] The protruding part 81 as the comb part is a straight bar shape without height difference in the axial direction, and is a flat plate shape of a substantially isosceles triangle in which a part of the curved surface of the pedestal surface 18 is recessed. The front end angle of the protruding part 81 is the sum of the apex angles of the first protrusions 13A, 13B and the second protrusions 14A, 14B of the first embodiment, and the protruding amount of the height in the protruding direction of the protruding part 81 is the same as the height of the connecting top walls 15A, 15B of the first embodiment.

[0102] As Figure 8 (b) shows that the protruding parts 81 of the comb body 8 are arranged at equal intervals in the axial direction, and the interval G8 between the protruding parts 81 on the pedestal surface 87 is equal to the narrower interval (the first specified interval) Da of the first embodiment.

[0103] In this experiment, the content of the mascara liquid was a black fiber-free mixed mascara, and the experimenters were ten women. In addition, the comb A used in the experiment was the comb 1 of the first embodiment, and the comb B was the comb 8 of the comparative example. The experimenters were not informed which comb corresponded to which of the present invention (under development) and the comparative example (already on sale as a product).

[0104] (1) An unused comb (comb A, comb B) was placed into the bottle filled with the content liquid, and the cosmetic applicators respectively equipped with comb A and comb B were rotated three times to the left and right, so that the content liquid was well mixed in the comb.

[0105] (2) For each person, the combs A and B with the mascara liquid attached were each applied to the left and right eyelashes 20 times.

[0106] (3) The completion conditions of the left and right eyelashes after application were compared and evaluated. During the evaluation, the experimenters evaluated the completion conditions of their own eyelashes reflected in the table mirror, the wash mirror, or / and the wall mirror.

[0107] In addition, it was up to each person to decide which of the left and right eyelashes to apply with comb A and comb B.

[0108] Figure 9 It is a graph showing the results of a questionnaire survey on the completion conditions after the use of the combs according to the first embodiment and the comparative example.

[0109] The evaluation items were "the completion of 'comb A' is separated and uniform", "the completion of 'comb A' is slightly separated and uniform", "the same", "the completion of 'comb B' is slightly separated and uniform", "the completion of 'comb B' is separated and uniform". Among the 10 experimenters, each person gave one answer.

[0110] As Figure 9 shown, the total number of people who answered "the completion of 'comb A' is separated and uniform" and "the completion of 'comb A' is slightly separated and uniform" was 7, which was more than the 1 person who answered "the completion of 'comb B' is separated and uniform". From this, it can be seen that comb A, that is, the comb 1 according to the first embodiment, has the effect of feeling "separated and uniform completion" compared with comb B, that is, the comb 8 according to the comparative example.

[0111] (Experimental Example 3)

[0112] Furthermore, regarding the completion conditions of Experimental Example 2, the inventors of the present invention took photos of the eye areas of 2 experimenters. Figure 10 It is a photo showing the completion conditions after the use of the combs 1 and 8 according to the first embodiment and the comparative example.

[0113] As shown in the photo on the left, when applying mascara liquid with the comb-shaped comb body 8 of the straight bar involved in the comparative example, each one or two or three eyelashes are separated radially. Figure 10 Since it is a scaled-up photograph, the separation of each individual eyelash can be visually confirmed. However, at a distance of more than 45 cm from a friend or acquaintance, i.e., the personal distance, or more than 120 cm from a colleague, i.e., the social distance, the applied eyelashes are thinned and separated, so there is a possibility that the eyelashes cannot be seen clearly.

[0114] In contrast, as shown in the photo on the right, when applying mascara liquid with the comb body 1 according to the first embodiment, several eyelashes converge into a tuft, and the tufts are at natural intervals. It is considered that the reason is that by combing while squeezing the hairs near the relatively wide interval Gb with the comb body 1, the direction of the tips of the eyelashes is thus arranged.

[0115] On the premise that the face including the eyelashes is observed from a distant position, in the above Figure 9 In the questionnaire results, the experimenter evaluated by observing a mirror at a certain distance away without looking at the hand mirror. Through Figure 9 、 Figure 10 It can be seen that by intentionally bunching the eyelashes with the comb body 1, for the side with a tuft feeling, the separation of the eyelashes can be clearly seen from a certain distance away.

[0116] Thus, the cosmetic applicator having the comb body 1 according to the first embodiment of the present invention uses a separate finishing mascara comb body. As Figure 1 such, by changing the use position in the shaft portion, it is also possible to arrange the eyelashes in a desired direction and create a tuft feeling only by performing a minimum action of combing the eyelashes.

[0117] (Experimental Example 4)

[0118] The present experimenters conducted a comparative experiment on the liquid adhesion of the comb body. Figure 11 It is a diagram of the liquid adhesion of the comb body according to the first embodiment and the comparative example.

[0119] In addition, the content liquid of the mascara used in this experiment is a so-called fiber black mascara liquid containing black mascara liquid. The content contains the following components. Hydrogenated polyisobutene, cyclomethicone, trimethylsilyloxy silicic acid, dextrin palmitate, polyethylene, microcrystalline wax, isostearic acid, triisooctanoin, polymethylsilsesquioxane, nylon-6, tocopheryl acetate, macadamia nut oil, BHT, silica, tocopherol, carbon black.

[0120] (Experimental Method)

[0121] (1) Place the unused comb bodies (Comb Body A and Comb Body B) in the bottle filled with the content liquid, and rotate the cosmetic applicators equipped with Comb Body A and Comb Body B respectively to the left and right 3 times to mix the content liquid well on the comb bodies.

[0122] (2) Photograph the liquid attachment state of the comb bodies (Comb Body A and Comb Body B) when pulling out the comb bodies from the bottle.

[0123] (3) Photograph the attachment state to the cotton (Comb Body A and Comb Body B) when gently pressing the comb bodies on the cotton.

[0124] The above operations are performed 5 times, and the best is as Figure 11 shown.

[0125] From Figure 11 the photos, it can be seen that in the comparative example and the present embodiment, the mascara liquid uniformly adheres to the comb bodies. In addition, regarding the comb body itself, comparing Comb Body 1 related to the first embodiment and Comb Body 8 related to the comparative example, in the comparative example, the protruding portion 81 has an attachable amount that can be visually confirmed. In contrast, in the first embodiment, the protruding portions 11 and 12 faintly have liquid attachment, and there is more liquid attachment (including liquid) to Comb Body 1.

[0126] In addition, regarding the cotton, comparing Comb Body 1 related to the first embodiment and Comb Body 8 related to the comparative example, in the comparative example, it is dispersed at each thin and equal interval D8 and adheres to the mascara liquid. In contrast, in the first embodiment, in each relatively wide interval Db, more mascara liquid converges and adheres in large amounts. Therefore, the attachment amount to the cotton is more.

[0127] From this, it can be known that Comb Body 1 related to the first embodiment can make more mascara liquid adhere compared to Comb Body 8 related to the comparative example. Therefore, Comb Body 1 related to the present invention can increase the attachment amount to the eyelashes for each combing action.

[0128] <Second Embodiment>

[0129] Next, Figure 12 explain the cosmetic applicator related to the second embodiment of the present invention. Figure 12 is an explanatory view of the front end portion of Comb Body 5 related to the second embodiment of the present invention. As Figure 12 shown, Comb Body 5 is a part of the front end side of Comb Body 5 in the cosmetic applicator having a grip portion 3 and a shaft portion 2.

[0130] In the present embodiment, a plurality of protruding portions 50 protruding from a pedestal surface (one surface) 53 extending in a specified width in the axial direction of the shaft portion are arranged on the front end side of the shaft portion 2. Comb Body 5 related to the present embodiment has a pedestal surface 53 on the abdominal side and a back surface 54.

[0131] The plurality of protrusions 50 of the present embodiment include a flat first protrusion plate 51 and a second protrusion plate 52.

[0132] The first protrusion plate 51 is inclined with respect to the axial direction such that the first side edge E3 of the pedestal surface (one surface) 53 is located on the front end side in the axial direction and the second side edge E4 opposite to the first side edge E3 is located on the rear end side. The second protrusion plate 52 is inclined with respect to the axial direction such that the first side edge E3 of the pedestal surface 53 is located on the rear end side and the second side edge E4 is located on the front end side. With such a shape, in the present embodiment, the contour of the root of each protrusion plate 51, 52 includes portions with different axial positions. The first protrusion plate 51 and the second protrusion plate 52 are alternately arranged in the axial direction.

[0133] In addition, as Figure 12 shown, the first protrusion plate 51 and the second protrusion plate 52 are flat and have an isosceles triangle shape that becomes higher toward the center in the width direction. By making the protrusion plates 51, 52 each have an isosceles triangle shape, it is possible to easily bring the protrusion plates 51, 52 close to the root of the eyelashes.

[0134] In the present embodiment, on both end portions in the width direction perpendicular to the axial direction of the pedestal surface 53, that is, on the side edges E3, E4, the protrusion plates 51, 52 are arranged in an alternating manner with a wide interval Gc and a narrow interval Gd in the axial direction.

[0135] In the arrangement state where the first protrusion plate 51 and the second protrusion plate 52 are alternately arranged, suitably, the plate-to-plate distance (first specified interval) Gc on the narrow side is 0.3 to 0.5 mm, and the plate-to-plate distance (second specified interval) Gd on the wide side is 1.2 to 1.5 mm. Then, suitably, the plate-to-plate distance Gd on the wide side is 3 to 4 times the plate-to-plate distance Gc on the narrow side.

[0136] As Figure 12 shown, when the comb body 5 according to the present embodiment combs the eyelashes, the eyelashes that enter the wider second specified interval Gd are exposed through the first specified interval Gc which is a narrower space. Therefore, by combing while twisting the nearby hairs, they are sorted into bundles of a small number of eyelashes each (separated), and the direction of the tips of the eyelashes is sorted.

[0137] In this way, the cosmetic applicator having the comb body 5 according to the present embodiment can sort the eyelashes into a desired direction and create a tufted feeling with only a minimal action of combing the eyelashes.

[0138] <Third Embodiment>

[0139] Figure 13 It is an explanatory view of a comb body 6 according to the third embodiment of the present invention. Figure 13 (a) is a plan view of the abdominal side, Figure 13(b) is a perspective view of the front end of the shaft portion. Figure 13 (a), Figure 13 The comb body 6 shown in (b) is a part of the front end side of the comb body 6 in the cosmetic applicator having the grip portion 3 and the shaft portion 2.

[0140] In the present embodiment, on the front end side of the shaft portion, a plurality of protrusions 61 protruding from a pedestal surface (one surface) 62 extending in a specified width in the axial direction of the shaft portion are arranged.

[0141] In the present embodiment, when viewed from the front direction of the pedestal surface (one surface) 62, the plurality of protrusions 61 are in a quadrangular pyramid shape with the center in the width direction swollen like a rhombus shape. Specifically, in a front view, the plurality of protrusions 61 are in a quadrangular pyramid shape with the diagonal part of the rhombus as the side, and in a front view, the long diagonal of the rhombus extends in the width direction and the short diagonal extends in the axial direction. With such a shape, the contour of the root of each protrusion of the plurality of protrusions 61 includes portions with different axial positions.

[0142] In the present embodiment, the same protrusions 61 are arranged axially in the central direction of the pedestal surface 62, and at the front end portion of the pedestal surface 62, a plurality of similar-shaped protrusions 61 that become smaller toward the front end side are arranged.

[0143] Since the plurality of protrusions 61 are in a quadrangular pyramid shape, the cross section in the width direction of each protrusion 61 is in an isosceles triangle shape. With the cross section in the width direction of each protrusion 61 being in an isosceles triangle shape, it is easy to bring the protrusion 61 close to the root of the eyelash.

[0144] In the present embodiment, at both end sides in the width direction of the protrusion 61, that is, the axial protrusion interval (spacing) Ge between the vertices of the long diagonals of adjacent rhombuses determined in a front view is preferably 0.3 to 0.5 mm. In addition, at the center in the width direction of the protrusion 61, that is, the axial protrusion interval (spacing) Gf between the vertices of the short diagonals of adjacent rhombuses determined in a front view is preferably 1.2 to 1.5 mm. Then, appropriately, the protrusion interval Gf at both end sides in the width direction is 3 to 4 times the protrusion interval Ge at the center in the width direction.

[0145] As Figure 13 In the comb body 6 according to the present embodiment shown, when combing the eyelashes with the comb body 6, the eyelashes that enter the wide interval (second specified interval) Gf at both end sides of the side edges E5 and E6 are exposed again through the narrow interval (first specified interval) Ge after entering the narrow interval (first specified interval) Ge. Therefore, by combing while squeezing the nearby hairs, the direction of the tips of the eyelashes is sorted, and they are sorted and separated into bundles of a small number of eyelashes each.

[0146] Thus, the cosmetic applicator having the comb body 6 according to the present embodiment can arrange the eyelashes in a desired direction and create a bundled lash effect with a minimal action such as combing the eyelashes.

[0147] As described above, the preferred embodiments of the present invention have been described in detail. However, the present invention is not limited to such specific embodiments, and various modifications and changes can be made within the scope of the gist of the embodiments of the present invention described in the claims.
