[0027] The mascara applicator of the present invention is as follows.
[0028] It contains a shaft and multiple comb teeth.
[0029] The shaft body has a surface extending axially at its front end.
[0030] A recessed portion is formed on the surface in a direction perpendicular to the shaft.
[0031] The plurality of comb teeth are formed to protrude from the bottom surface of the recess beyond the surface.
[0032] The multiple comb teeth are arranged in a linear pattern along the axial direction.
[0033] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Furthermore, in the drawings, unless otherwise specified, the same or corresponding structures are indicated by the same reference numerals, or the same reference numerals may not be used, and sometimes descriptions are omitted. The drawings are schematic diagrams to aid in understanding the invention.
[0034] Figure 1 This is a top view of a mascara applicator according to one embodiment of the present invention. Figure 2 yes Figure 1 The diagram shows a cross-sectional view along line II. The mascara applicator 1 includes a shaft 2 and a grip 3. Furthermore, the shaft 2 has multiple comb teeth 5 at its front end 4, which serve as the applicator for mascara liquid, etc. Figure 6 The positions of the comb teeth shown are... Figures 1 to 5 The positions of the comb teeth shown are roughly corresponding. Furthermore, for ease of understanding of the description of the various structures of this invention, the comb teeth 5 are sometimes referred to as comb teeth 5A1, 5A2, 5A3, 5A4, 5A5, 5A6, 5B1, 5B2, 5B3, 5B4, 5B5, 5B6, 5C1, 5C2, 5C3, 5C4, 5C5, and 5C6. Comb teeth 5A1 to 5A6 are the comb teeth of comb tooth row A, comb teeth 5B1 to 5B6 are the comb teeth of comb tooth row B, and comb teeth 5C1 to 5C6 are the comb teeth of comb tooth row C. Furthermore, as... Figure 2 , 3 As shown, the mascara applicator 1 may have a curved surface r (arc) between the comb teeth 5 and the concave bottom surface 12.
[0035] In addition, in the attached diagram, the first direction D1 is the axial direction of the shaft, that is, the length direction of the shaft; the second direction D2 is the direction perpendicular to the shaft, that is, the height direction of the shaft; and the third direction D3 is the direction of the mascara applicator when viewed from the side, that is, the width direction of the shaft.
[0036] The grip 3 is mounted on the shaft 2 and is the part that the user holds during use. Furthermore, the grip 3 may have a structure that allows it to be attached to a container holding cosmetics and a cap that can be threaded or snapped shut. Additionally, the shaft 2 may be detachable from the grip 3 or may be integrally formed with the grip 3.
[0037] The mascara applicator 1 of this embodiment is a mascara applicator in which multiple comb teeth 5 are integrally formed with a shaft 2. That is, at the front end 4 of the shaft, an applicator body, i.e., multiple comb teeth 5, for applying liquid mascara or the like to the eyes is integrally provided. With the multiple comb teeth 5, cosmetics such as liquid mascara can be applied to the eyelashes while combing them. In addition, the multiple comb teeth 5 can also be used to apply liquid mascara or the like to the lower eyelashes, not just the upper eyelashes.
[0038] Cosmetic products such as liquid mascara filled in the bottle will adhere to the comb teeth 5. The cosmetic products adhered to the comb teeth 5 are not limited to liquid mascara (mascara), but can also be eyelash growth serum, eyelash base coat, eyelash coating agent, eyelash extension coating agent, eyeliner, and cosmetic combinations that can be used for multiple purposes, such as mascara and eyeliner.
[0039] In the mascara applicator 1, at least the shaft 2 and the comb teeth 5 can be integrally formed by resin molding. As the resin material, thermoplastic resin is preferred, for example, elastomers, polyethylene, polypropylene, polystyrene, polyethylene terephthalate, polybutylene terephthalate, polycarbonate, polyacetate, nylon, etc. can be used.
[0040] exist Figure 1 In the middle, shaft 2 has an upper surface in the height direction, namely surface 10. Surface 10 is as follows: Figure 2 The surface shown includes two top surfaces 9, 9 formed on the upper surface of the shaft 2 (virtual surfaces), and extends along the top surfaces 9, 9 in the first direction D1 (axial direction of the shaft). The line seen when viewing surface 10 from a third side towards D3 (width direction of the shaft) coincides with the line seen when viewing top surface 9 from a third side towards D3. Figure 4 ).exist Figure 1 , 2 In the middle, a recess 11 is formed on the surface 10, which is recessed in the second direction D2 (the height direction of the axis). Multiple comb teeth 5 are formed to protrude from the bottom surface 12 of the recess and extend beyond the surface 10. When applying mascara liquid, the mascara liquid will enter the recess 11. Therefore, even if the mascara applicator 1 is inserted into a container with a squeezer containing mascara liquid and squeezed, a certain amount of mascara liquid can be ensured at the root of the comb teeth 5. Figure 2 This is a cross-sectional view of the recess 11, which intersects the shaft 2 perpendicularly. Figure 2 In the cross-section of the shaft, the edge corresponding to the bottom surface 12 of the recess is curved. When the user applies mascara liquid to the eyelashes using the mascara applicator 1, the axis of the mascara applicator 1, i.e., the first direction D1, is placed along the horizontal width direction of the eye. While combing the eyelashes with the comb teeth 5, the user moves the shaft 2 up and down or rotates it, thereby causing the eyelashes to enter between the comb teeth. At this time, when the eyelashes contact the bottom surface 12 of the recess, the shape of the eyelashes can conform to the shape of the recess 11, thereby curling the eyelashes.
[0041] exist Figure 1 In the mascara applicator 1, multiple comb teeth 5 are arranged along the first direction D1 to form three columns (comb tooth column A, comb tooth column B, and comb tooth column C). The number of columns formed by the multiple comb teeth 5 arranged along the first direction D1 can be a single column or multiple columns, but from the perspective of efficiency in applying mascara liquid to the eyelashes, multiple columns are preferred.
[0042] exist Figure 1 In the mascara applicator 1, multiple comb teeth 5 are arranged linearly along a first direction D1 to form a row. Here, from the front end 4 of the shaft towards the grip 3, each comb tooth in the comb tooth row A is referred to as comb tooth 5A1, comb tooth 5A2, comb tooth 5A3, comb tooth 5A4, comb tooth 5A5, and comb tooth 5A6. Figure 1In the mascara applicator 1, the comb teeth in column A are arranged linearly, specifically in a straight line. However, the arrangement of these comb teeth is not particularly limited, as long as they are linear within a single column. They can be arranged in a straight line, curve, wave, or irregular shape, or a combination of two or more of these. Furthermore, when the mascara applicator 1 has multiple columns of comb teeth arranged linearly along the first direction D1, the combination of arrangement patterns of the comb teeth in each column can be the same or different. For example, in... Figure 1 In this example, the arrangement of multiple comb teeth in each column is the same; comb tooth rows A, B, and C are all arranged in a straight line. However, for example, comb tooth row A may be curved, comb tooth row B may be irregular, and comb tooth row C may be wavy. The combination of multiple comb tooth arrangements in each column can also be different.
[0043] In the mascara applicator of the present invention, the front end of the comb teeth preferably has a portion of a spherical shape. For example, in Figure 2 In this design, the front end 7 of the comb teeth has a portion of a spherical body. When the front end of the comb teeth has a portion of a spherical body, it is easy to make the eyelashes appear fuller and more voluminous. Based on this, it is easy to comb the eyelashes appropriately, creating a makeup effect with a suitable spacing between the lashes. Furthermore, when the front end of the comb teeth has a structure with a portion of a spherical body, the processing of the mold used to manufacture the mascara applicator becomes easier, thus making it easier to manufacture the mascara applicator of this invention. In addition, in this embodiment, the spherical body is not limited to a standard sphere or a shape close to a standard sphere, but also includes the concept of an ellipsoid or a sphere having a flat portion on a portion of its surface.
[0044] Furthermore, the comb teeth in the mascara applicator of the present invention, such as Figure 3 As shown, the front end of the comb teeth can have an inclined shape, and the front end of the comb teeth can be flat or curved. Furthermore, the inclination angle T of the inclined shape of the front end of the comb teeth, relative to the plane Q formed by the first direction D1 and the third direction D3, which intersects the central axis S of the comb teeth perpendicularly, is preferably 10° to 80°, more preferably 30° to 60°, and even more preferably 40° to 50°. When the inclination angle of the inclined shape of the front end of the comb teeth relative to the plane Q is 10° to 80°, it is easy to make the eyelashes appear fuller. Furthermore, since the front end of the comb teeth is flat or curved, it is easy to comb the eyelashes appropriately, creating a makeup effect with an appropriate spacing between the lashes. In addition, in Figure 3 In the middle, the front end 7 of the comb teeth has an inclined shape, and the front end of the comb teeth is planar (truncated cone shape). Furthermore, in Figure 3 In the middle, the tilt angle T of the inclined shape of the front end of the comb tooth is 45° relative to the plane Q.
[0045] Furthermore, the shape of the comb teeth in the mascara applicator of the present invention can be circular, elliptical, or polygonal in a top view. Figure 1In the top view, the comb teeth 5 are circular. Furthermore, the width L1 of the comb teeth 5 is preferably 0.6mm to 1.1mm, more preferably 0.7mm to 1.0mm, and even more preferably 0.8mm to 0.9mm. The width of the comb teeth 5 refers to the maximum thickness of the comb teeth (or the diameter in the top view if the comb teeth are cylindrical). When the width L1 of the comb teeth 5 is 0.6mm to 1.1mm, it is easier to make the front end of the comb teeth have a shape that includes a portion of a sphere. Furthermore, when the front end of the comb teeth has an inclined shape, it is easier to reduce the inclination angle of the inclined shape of the front end of the comb teeth relative to the surface perpendicular to the central axis of the comb teeth, thereby enabling the manufacture of a mascara applicator that is less prone to clumping, such as for mascara.
[0046] In addition, Figure 2 , 3 In this design, the central axis S of the comb teeth is parallel to the second direction D2, but it can also have an inclination angle within ±45° relative to the second direction D2 (the direction that intersects the shaft perpendicularly). Furthermore, when the central axis S of the comb teeth has an inclination angle relative to the second direction D2, the inclination direction is not particularly limited and can be any direction around the central axis S within 360°.
[0047] In the mascara applicator of the present invention, the comb teeth do not overlap in its side view. Furthermore, as... Figure 1 As shown, even when the mascara applicator 1 has multiple rows of comb teeth, the comb teeth do not overlap in the side view of the mascara applicator 1.
[0048] Figure 4 It's a side view. Figure 1 The image (side view) of the mascara applicator 1 is viewed from a third-party perspective (D3). Figure 1 The image shows mascara applicator 1. Figure 4 In the image, starting from comb tooth 5A1, every two comb teeth can be seen arranged along the first direction D1, with each comb tooth in row A. Specifically, in... Figure 4 In the middle, starting from comb tooth 5A1, every two teeth you can see comb teeth 5A2, 5A3, 5A4, 5A5, and 5A6. Furthermore, in... Figure 4 In the image, between the teeth of comb row A, you can see comb teeth from different rows than those in comb row A, namely the teeth of comb row B and comb row C. All comb teeth do not overlap. For example, in... Figure 4In the side view of the mascara applicator 1, comb teeth 5B1 and 5C1 are visible between comb teeth 5A1 and 5A2, and comb teeth 5B2 and 5C2 are visible between comb teeth 5A2 and 5A3. Thus, as each comb tooth is visible, the multiple comb teeth of the mascara applicator 1 do not overlap in the side view. With this structure, eyelashes enter between adjacent comb teeth arranged axially and are divided into multiple bundles, thus easily forming bundled eyelashes after applying mascara. Furthermore, if the mascara applicator has multiple rows of axially arranged comb teeth, the eyelash bundles separated by the first row can be further divided by other rows of comb teeth, thereby increasing the bundled appearance of the eyelashes after applying mascara. In addition, Figure 1 In the mascara applicator 1, the first column of comb teeth can be either column A or column C. When the first column of comb teeth is column A, the other columns of comb teeth are columns B and C; when the first column of comb teeth is column C, the other columns of comb teeth are columns B and A.
[0049] Furthermore, in the side view of the mascara applicator, the distance between the comb teeth is preferably 0.3mm to 0.7mm. When the distance between the comb teeth in the side view of the mascara applicator is 0.3mm to 0.7mm, it is easy to make the mascara applicator have a structure where the comb teeth do not overlap in the side view. In addition, because the distance between the comb teeth is wider, when the mascara applicator is inserted into a container with a squeezer containing liquid mascara, excess liquid mascara is easily removed from the front part of the comb teeth. Therefore, when applying liquid mascara, eyelashes are more likely to enter between the comb teeth, thus easily forming clumpy eyelashes. In addition, "the distance between the comb teeth in the side view" refers to the distance viewed from a third-party perspective (D3). Figure 1 The shortest distance between the comb teeth when using a mascara applicator, for example, in Figure 4 , 6 In the middle, it refers to the shortest distance L2 between comb teeth 5A1 and 5B1. Figure 6 In the middle, it refers to the shortest distance L2 between comb teeth 5B1 and 5C1, the shortest distance L2 between comb teeth 5C1 and 5A2, etc.
[0050] Furthermore, in a comb row with multiple comb teeth arranged axially, the spacing between adjacent comb teeth arranged axially is preferably 3.9 mm to 4.5 mm. When the spacing between adjacent comb teeth arranged axially is 3.9 mm to 4.5 mm, it is easy to make the mascara applicator have a structure where the comb teeth do not overlap in the side view. In addition, because the distance between the comb teeth is widened, when the mascara applicator is inserted into a container with a squeezer containing mascara liquid or the like and squeezed, excess mascara liquid or the like is easily removed from the front part of the comb teeth. Therefore, when applying mascara liquid or the like, eyelashes are more likely to enter between the comb teeth, thereby easily forming eyelashes with a bundled feel. In addition, "the spacing between adjacent comb teeth arranged axially" refers to, in Figure 6 In, for example, in comb tooth row A, the distance L3 is the distance between the center of the diameter of comb tooth 5A1 in its top view and the center of the diameter of comb tooth 5A2 adjacent to comb tooth 5A1 in its top view. Furthermore, this distance L3 is... Figure 4 The middle is the distance between the central axis of comb tooth 5A1 and the central axis of comb tooth 5A2.
[0051] In addition, from Figure 4 As can be seen, the position R on the shaft 2 of the mascara applicator 1 forms the recess 11, which is observed from the side view (viewed from the third direction D3). Figure 1 The mascara applicator 1 is curved. Furthermore, this curve rises upwards from the front end of the shaft 2 towards the center of position R. Specifically, in Figure 4 In this design, at position R on the shaft 2 of the mascara applicator 1, where a recess 11 is formed, the central portion R2 of position R is higher than the front end portion R1 of the shaft 2 at position R in terms of the height of the surface 10 extending axially along the shaft 2. Furthermore, the height of the surface 10 extending axially along the shaft 2 at position R is approximately the same as or equal to the height of the grip portion R3 of position R. Alternatively, as another embodiment, the height of the surface 10 extending axially along the shaft 2 at position R can be higher or lower than the grip portion R3 of position R. The term "height of the surface extending axially along the shaft" refers to the length of a vertical line from the surface containing the bottom surface of the shaft 2 and parallel to the shaft 2 to the top surface 9 when the mascara applicator 1 is viewed from the side. If other comb teeth are formed on the bottom surface of the shaft 2, the term refers to the length of a vertical line from the surface containing the front end of the other comb teeth and parallel to the shaft 2 to the top surface 9.
[0052] Because the surface 10 extending axially along the shaft 2 at the location R where the recess 11 is formed on the shaft 2 has the aforementioned height variation, the surface 10 extending axially along the shaft 2 at location R can be inclined. Therefore, the location R where the recess 11 is formed on the shaft 2 can be tilted in the side view (viewed from the third direction D3). Figure 1 The mascara applicator (1) is curved.
[0053] from Figure 2 , 4 It can be seen that in the mascara applicator 1, the height of the surface 10 of the front end portion R1 of the shaft 2 located at position R is lower than the height of the surface 10 of the central portion R2 located at position R.
[0054] Furthermore, in the side view of the mascara applicator 1, at the position R where the recess 11 is formed on the shaft 2, the distance from the surface 10 to the tip of a certain row of comb teeth is preferably within a certain range within that row. When the position R where the recess 11 is formed on the shaft 2 of the mascara applicator 1 is curved in the side view, if the distance from the surface 10 to the tip of a certain row of comb teeth is within a certain range, the virtual line connecting the vertices of the multiple comb teeth 5 in that row will also easily appear curved in the side view. With this structure, the appearance of the mascara applicator 1 can be highly designed. To achieve this structure, for example, at position R, the distance from the surface 10 to the tip of the comb teeth is preferably 1.5 mm to 2.5 mm.
[0055] Furthermore, from the perspective of ease of manufacturing the mascara applicator, the distance from the surface 10 to the tip of each of the multiple comb teeth 5 is preferably the same on all comb teeth, but it can also be different on all comb teeth, or different according to the comb tooth group. Additionally, the distance from the surface 10 to the tip of the comb teeth can also be different according to the comb tooth rows arranged axially. For example, if the distance from the surface 10 to the tip of comb teeth 5A1-5A6 and 5C1-5C6 is the same, then regardless of whether the mascara applicator 1 is used with the left or right hand, the makeup effect after applying mascara liquid, etc., is easily consistent. In this case, the distance from the surface 10 to the tip of comb teeth 5B1-5B6 is preferably longer than the distance from the surface 10 to the tip of comb teeth 5A1-5A6 and 5C1-5C6, but it can also be the same or shorter. Furthermore, the distance from the surface 10 to the tip of comb teeth 5B1-5B6 is preferably the same, but it can also be different. Figure 4 In the mascara applicator 1, the distance from the surface 10 to the tip of the comb teeth is basically the same in the axially arranged comb teeth row. However, the comb teeth 5A1 and 5C6 are located at the front end of the recess 11 where the width of the recess 11 bends and narrows in the top view. Figure 6 Therefore, the curve of surface 10 in the side view bends upward at both ends of position R. Figure 4 Therefore, the distance from surface 10 to the tip of comb teeth 5A1 and 5C6 is different from the distance from surface 10 to the tip of comb teeth for other comb teeth. Figure 4 ).
[0056] Furthermore, the length of the comb teeth in the mascara applicator of the present invention is preferably 2.0 mm to 3.0 mm. When the comb tooth length is 2.0 mm to 3.0 mm, it is suitable for applying liquid mascara to the eyelashes. Additionally, the length of the comb teeth refers to the distance from the tip of the comb tooth to the intersection of the central axis of the comb tooth and the bottom surface of the concave portion. Figure 4 The position R where the shaft 2 forms the recess 11 is curved in the side view, but the position R can also be straight.
[0057] Figure 5 yes Figure 1The front view of the mascara applicator shown is viewed from the front end 4 of the shaft towards the grip 3 in the first direction D1. Figure 4 The image shows mascara applicator 1. Figure 5 For example, in comb row A, the position of the front end of each comb tooth rises in stages from the front end 4 side of the shaft towards the gripping part 3, that is, from comb tooth 5A1 towards comb tooth 5A4. Furthermore, the position of the front end of each comb tooth in comb rows B and C also rises in stages from the front end 4 side of the shaft towards the gripping part 3. This is because... Figure 4 At position R where the central shaft 2 forms the recess 11, the distance between the surface 10 and the intersection of the central axis S of the comb teeth 5 and the bottom surface 12 of the recess in a certain column is within a certain range in that column. Furthermore, the central portion R2 at position R is higher than the front end portion R1 of the shaft 2 at position R, extending axially along the shaft 2. This structure allows the front ends of the comb teeth of the mascara applicator to more easily adhere to the eyelashes, thus making it easier to apply mascara liquid and other products with fewer strokes.
[0058] In addition, Figure 5 In the front view of the mascara applicator 1, the teeth 5A1 of comb row A overlap with the teeth 5B1 of comb row B, and the teeth 5A1 are located on the side closer to the front end 4 of the shaft than the teeth 5B1. Furthermore, the teeth 5B1 of comb row B overlap with the teeth 5C1 of comb row C, and the teeth 5B1 are located on the side closer to the front end 4 of the shaft than the teeth 5C1. Thus, the teeth of comb rows A, B, and C overlap when the mascara applicator 1 is viewed from the front. This structure makes it easier to adjust the mascara applicator to an easy-to-use size.
[0059] Figure 6 yes Figure 1 The image shows a top view of the front end portion of the mascara applicator shaft. In the mascara applicator of the present invention, the longest distance L4 of the recess 11 in the first direction D1 (the axial direction of the shaft) is preferably 20 mm to 30 mm. Furthermore, the longest distance L5 of the recess 11 in the third direction D3 (the direction perpendicular to the axial direction of the shaft) is preferably 2 mm to 5 mm. With this structure, the mascara applicator can be made in a size that is easy to use.
[0060] Figure 7 yes Figure 4 The top view of the mascara applicator shown is viewed from the other 6 sides in the second direction D2. Figure 4 The image shows mascara applicator 1. Figure 7In this design, multiple additional comb teeth 6 are located at positions R forming the recess 11 and are integrally formed with the shaft body 2. However, the multiple additional comb teeth 6 may not be integrally formed with the shaft body. Furthermore, the multiple additional comb teeth 6 may be part of the shaft body, or they may not be part of the shaft body, or they may be separable from the shaft body. By providing multiple additional comb teeth 6, after applying mascara liquid to the upper lashes, the user can apply the mascara liquid to the lower lashes without changing the direction of the mascara applicator. In addition, the multiple additional comb teeth 6 are mainly used for applying mascara liquid to the lower lashes, but they can also be used for applying mascara liquid to the upper lashes.
[0061] Furthermore, the shape and number of the other comb teeth 6 are not limited as long as they are shaped to allow for the proper application of mascara liquid, but from the viewpoint of ease of use and efficiency in applying mascara liquid, they are preferably located on the shaft at the position forming the recess. Additionally, the distance L6 between the other comb teeth is preferably 0.25mm to 0.7mm, and the width L7 of the other comb teeth 6 is preferably 0.5mm to 1.1mm. When the other comb teeth have this structure, it is easy to form eyelashes with a moderately tight feel. Furthermore, the distance L6 between the other comb teeth refers to the shortest distance between the other comb teeth, and the width L7 of the other comb teeth refers to the maximum length value of the other comb teeth in the first direction D1.

Additionally, the liquid mascara is applied to the lower eyelashes via multiple other comb teeth 6. Furthermore, the width of the comb teeth 5A1-5A6, 5B1-5B6, and 5C1-5C6, the distance between the comb teeth, the spacing, the concave size, the length of the comb teeth, and the shape of the front end of the comb teeth of the mascara applicator used, as well as the distance between the comb teeth and the width of the comb teeth of the other comb teeth 6, are shown below.
