Description

  The present invention relates to a mascara applicator.

  In recent years, long feelings have been demanded for mascara drugs in addition to the curl effect. In order to produce a long feeling with a conventional mascara brush, it was necessary to increase the hair bundle while spreading the eyelashes many times in order to apply a large amount of drug to the eyelashes. However, since it takes time to increase the hair bundle while curling and spreading eyelashes, the drug applied earlier solidifies during that time, and if you brush the solidified place with a brush, the applied drug will peel off. It becomes a lump. It is difficult to correct the mascara drug if it adheres to the eyelashes in a dull state. For example, you have to use a different comb for eyelashes to wipe off the llama. This requires skillful and delicate operations and is not a kind of operation that anyone can easily do.

  An electric mascara brush intended to prevent the occurrence of lumps has been proposed (see Patent Document 1). This mascara brush automatically rotates the brush head at a constant speed by installing a small motor inside the hollow handle of the brush, providing a gear that moderately reduces the rotation speed, and connecting the shaft of the mascara brush to it. Is. However, since the shape of the brush head itself is known, it is not sufficient to effectively prevent the occurrence of lumps. Moreover, since it is an electric type, a mechanism will be complicated.

  Regarding the shape of the brush head, a screw brush is also known in which a brush member is formed in a W shape by forming a core member to which brush hair is attached into a curved shape formed by three arcs (Patent Document 2). reference).

  However, in this brush, the rigidity of the brush bristle loses the viscosity of the medicine, which may make it unreliable. In addition, the bristles of the bristles are randomly projected from the center of the shaft toward the outside, and the bristles are composed of bristles with a sharp tip like a wire. Scratches can cause lumps. In addition, the drug that is not applied to the eyelashes and remains on the surface of the hair group is solidified, which also causes lumps.

  The purpose of the present invention is to eliminate the drawbacks of the conventional technology described above, such as generating lumps due to solidification of the drug during work because it takes time to increase the hair bundle while curling and extending eyelashes. An object of the present invention is to provide a mascara applicator.

The present invention is a mascara applicator in which an application part for applying a mascara drug is composed of an application part shaft and comb teeth, and the comb teeth are formed integrally with an annular piece and a protruding piece,
Using a plurality of comb teeth groups that form a set of two or more comb teeth, each set is arranged along the longitudinal direction of the application part axis,
In each set of comb teeth, each comb tooth is arranged such that when two adjacent comb teeth are viewed from the front, the protruding piece of the other comb tooth is located between the adjacent protruding pieces of one comb tooth. The above-mentioned object is achieved by providing a mascara applicator in which is disposed.

  In the present invention, the comb head is formed by integrally forming the annular piece and the protruding piece on the coating head, and the comb teeth are arranged so that fine irregularities are formed on the coating head. It is possible to increase the hair bundle while stretching the hair. During the operation of applying the mascara drug, lumps may be generated on the eyelashes, but when the comb teeth pass through the lumps adhesion portion, the dents can be caught by the irregularities. When the bumps are caught on the unevenness of the coating head, the shape is more rigid than the bristle brush, so that the piles can be removed from the eyelashes without losing the size of the hook and the adhesive force of the hook on the eyelashes. Furthermore, unlike the tip of a bristle brush, the top of the comb teeth has a rounded triangular shape, so it is unlikely that the drug will be scratched and peeled off when the drug-coated part is spread. . Therefore, unlike an electric brush, a complicated mechanism is not necessary, but it is possible to finish it neatly and neatly without requiring a skilled technique.

  The present invention will be described below based on preferred embodiments with reference to the drawings. 1 to 3 show an embodiment of the mascara applicator of the present invention.

  As shown in FIG. 1A, the mascara applicator 10 has an application head 12 at the tip of an application bar 11. As shown in FIGS. 1B and 1C, the application head 12 is provided with a plurality of comb teeth 20 at substantially constant intervals along the axial direction of the application bar 11. The mascara applicator 10 is manufactured, for example, by injection molding the application head 12 around the distal end core rod 11A of the application rod 11 by insert molding.

  In the coating head 12, as shown in FIGS. 2 and 3, the coating portion shaft 21 is attached to the outer periphery of the tip core rod 11A over the entire length of the tip core rod 11A of the coating rod 11. Comb teeth 20 are provided on the outer periphery of the application part shaft 21. Each comb tooth 20 has an annular piece 22 and a protruding piece 23. The annular pieces 22 are provided at a substantially constant interval along the axial direction of the application part shaft 21, and a plurality of annular pieces 22 are provided on the outer periphery of the application part shaft 21. The interval between the annular pieces 22 adjacent to each other in the axial direction of the application portion shaft 21 matches the groove width of the annular groove 13 described later. The protruding pieces 23 are provided at a plurality of positions at substantially constant intervals along the circumferential direction of the annular piece 22. The protruding piece 23 protrudes outward in the radial direction of the annular piece 22. In the present embodiment, the comb teeth 20 have a star shape including ten protruding pieces 23. The protruding piece 23 has a triangular shape with a rounded apex.

  In order to securely fix the application portion shaft 21 to the distal end core rod 11A of the application rod 11, one or a plurality of irregularities and circumferentially extending grooves (not shown) are formed on the surface of the distal end core rod 11A. It is preferable to do. Thereby, at the time of insert molding, the constituent material of the application portion shaft 21 is filled in the groove, and the application portion shaft 21 and the distal end core rod 11A are engaged. Further, when a convex portion (not shown) is formed on the surface of the tip core rod 11A, the convex portion is held by a mold during insert molding, so that the tip generated by the influence of injection pressure during molding of the coating head. There is also an effect of preventing runout between the core rod 11 </ b> A and the application portion shaft 21.

  As shown in FIG. 3, an annular groove 13 is formed around the application portion shaft 21 between the adjacent comb teeth 20 in the axial direction of the application portion shaft 21. Specifically, the annular groove 13 is formed by the annular piece 22 and the protruding piece 23 of one adjacent comb tooth 20 and the annular piece 22 and the protruding piece 23 of the other comb tooth 20. The width of the bottom of the annular groove 13 is preferably 0.2 to 0.8 mm. A mascara drug is held in the annular groove 13.

  In the present embodiment, a plurality of comb teeth groups that form a set of two or more comb teeth 20 are used, and each set is arranged along the longitudinal direction of the coating portion shaft 21 to configure the coating head 12. Yes. For example, in the tip portion of the coating head 12 shown in FIG. 1B, three comb teeth 20 having similar shapes form one comb tooth group 30, and three comb tooth groups 30 are formed. It is used. Further, in the central region of the coating head 12 shown in FIG. 1 (c), three comb teeth 20 having the same shape as each other form a set of comb teeth group 30. As a comb tooth group that forms a set of comb teeth 20, a plurality of types of comb teeth having different comb tooth diameters may be used, and a plurality of comb tooth groups that form a set of two or more different comb teeth may be used. it can.

  The mascara applicator 10 according to the present embodiment has one of the features in the manner in which comb teeth are arranged in each group of comb teeth group 30. Specifically, in each set of comb teeth group 30, when two comb teeth 20 adjacent to each other are viewed from the front, the other comb teeth 20 are adjacent to each other between the protruding pieces 23. Each comb tooth 20 is arranged so that the protruding piece 23 of the comb tooth 20 is located. This state will be described with reference to FIGS. 4 (a) and 4 (b).

  As described above, in this embodiment, a set of comb teeth group 30 is formed by three comb teeth. Three comb teeth in the comb tooth group 30 are denoted by reference numerals 20a, 20b, and 20c in FIGS. 4 (a) and 4 (b). When attention is paid to two adjacent comb teeth, for example, 20a and 20b, in this set of comb tooth group 30, between adjacent projecting pieces 23a and 23a in one comb tooth 20a, projecting piece 23b in the other comb tooth 20b. Is located. When attention is paid to two adjacent comb teeth 20b and 20c, the protruding piece 23c of the other comb tooth 20c is located between the adjacent protruding pieces 23b and 23b of the one comb tooth 20b. .

  Thus, in the set of comb teeth group 30, the positions of the apexes of the protruding pieces 23a, 23b, 23c of the comb teeth 20a, 20b, 20c are between the comb teeth in the circumferential direction of the comb teeth. Each comb tooth is arranged so that it may shift. This applies not only to the central area of the coating head 12 (area shown in FIG. 1C) but also to the tip of the coating head (area shown in FIG. 1B). When the coating head 12 is viewed from the side, it appears that a group of protruding pieces arranged in a shifted manner forms many fine irregularities. Therefore, when the mascara medicine is applied to the eyelashes using the mascara applicator 10 of the present embodiment, the movement of rotating the comb teeth is added during the application of the lump that is a lump protruding on the eyelashes. It becomes easy to get caught in the gap, and it is easy to remove lumps from the eyelashes by a synergistic effect with the high rigidity of the comb teeth.

  In addition, since the comb teeth in the present embodiment have a thickness obtained by molding, they have higher rigidity than a bristle brush. Therefore, when many unevenness | corrugations formed in the application | coating head 12 catch a dama, a dama can be removed from an eyelash, without losing the magnitude | size of a dama and the adhesive force to an eyelash.

  As is apparent from the above viewpoint, the rigidity of the comb teeth 20 in the application head 12 affects the dama removal performance. In particular, when the mascara drug has a high viscosity, the effect becomes significant. By forming the comb teeth 20 to a certain degree of hardness, the comb teeth 20 do not lose the viscoelasticity even when a high-viscosity mascara drug is used, and excessive deformation is prevented, and the effect of removing lumps is remarkable. It will be something. Moreover, the combing effect by the comb tooth 20 can fully be acquired by not making the comb tooth 20 too hard. From these viewpoints, in the present embodiment, the Shore hardness (A) of the annular piece 22 and the protruding piece 23 of the comb teeth 20 is preferably 45 to 120, and more preferably 50 to 90. As a result, the long effect by combing and the effect of removing lumps can be combined. The shore hardness (A) of the comb teeth 20 is measured by forming a comb tooth material on a sheet using a type A durometer according to JIS K7215.

  The Shore hardness of the comb teeth 20 can be adjusted within the above range by appropriately selecting the material constituting the comb teeth 20.

  The circumferential shift between the comb teeth in the set of comb teeth group 30 may be regular or irregular. The important point is that a deviation occurs in the circumferential direction between adjacent comb teeth. When viewed from the side, the application head 12 has a large number of fine irregularities in a group of protruding pieces that are displaced. Looks like they are forming. In this embodiment, as shown in FIG.4 (b), the shift | offset | difference of the circumferential direction between each comb tooth is regular. Specifically, the comb teeth 20a and the comb teeth 20b are shifted by 12 degrees. Similarly, the comb teeth 20b and the comb teeth 20c are also shifted by 12 degrees. The position of the protruding piece in the circumferential direction of the corresponding comb teeth in the three comb teeth included in the set of comb teeth group and the three comb teeth included in the comb tooth group adjacent thereto Are the same. In other words, the comb teeth 20a in a certain set of comb teeth group and the comb teeth 20a in the comb tooth group adjacent to the comb teeth group are located at the same position in the circumferential direction of the comb teeth. The same applies to the comb teeth 20b and 20c.

  A method for applying a mascara drug using the applicator 10 having the application head 12 having the characteristic shape as described above will be described with reference to FIG.

  First, the comb teeth 20 of the application head 12 of the mascara applicator 10 are immersed in a mascara drug supply container (not shown), and the excessive adhesion of the mascara drug adhering to each comb tooth 20 is squeezed off by the squeezing valve of the container. . The mascara applicator 10 stores the mascara drug between the comb teeth 20 adjacent in the axial direction, mainly between the annular piece 22 of the comb teeth 20 and the base end portion of the protruding piece 23.

  Next, as shown in FIG. 5A, the eyelashes are accurately guided into the annular groove 13 between the adjacent comb teeth 20, 20 in the application head 12, and the eyelashes are formed between the adjacent protruding pieces 23, 23. To pass. By this operation, the medicine stored in the annular groove 13 can be attached to the eyelashes. Then, the distance L (FIG. 5 (a)) to the eyelids of the comb teeth 20 is reduced, and the medicine is applied from the base of the eyelashes as shown in FIG. 5 (b).

  Next, as shown in FIG. 5 (c), the comb teeth 20 of the mascara applicator 10 are moved upward with respect to the upper eyelashes, and stored between the annular pieces 22 of the comb teeth 20 and the base ends of the protruding pieces 23. The applied mascara drug is applied to the eyelashes (FIGS. 5D and 5E).

  Next, a second embodiment of the present invention will be described with reference to FIG. Regarding the points that are not particularly described with respect to the present embodiment, the description of the above-described embodiment is applied as appropriate. In FIG. 6, the same members as those in FIGS. 1 to 5 are denoted by the same reference numerals.

  FIG. 6 shows another embodiment of the comb teeth group 30. The comb tooth group 30 in the present embodiment is composed of two comb teeth 25a and 25b having different shapes. However, both comb teeth have the same diameter. The comb teeth 25a have a star shape with six protruding pieces. On the other hand, the comb teeth 25b have a star shape having ten protruding pieces, like the comb teeth 20 shown in FIG. Similarly to the above-described embodiment, in this embodiment, when viewed from the front in a state where two comb teeth are overlapped, between the adjacent protruding pieces 26a and 26a in one comb tooth 25a, the other The protruding piece 26b of the comb tooth 25b is located. Therefore, also in this embodiment, the application head 12 of the brush 10 is in a state in which a large number of fine irregularities including the protruding pieces 26a and 26b of the comb teeth 25a and 25b are formed.

  In addition, in this embodiment, when the one protrusion piece 26b of the other comb tooth 25b is located between the adjacent protrusion pieces 26a and 26a in one comb tooth 25a, and when two pieces are located. Are mixed. However, this itself does not affect the effect of the present invention.

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment. For example, in the embodiment shown in FIG. 1, a set of comb teeth group 30 is composed of three comb teeth, but the number of comb teeth is not limited to this and may be two or four or more.

  Further, in each of the above-described embodiments, a set of comb teeth is constituted by three (two in FIG. 6) comb teeth, and a plurality of sets are used. The application head may be configured by combining two or more sets of comb teeth having different shapes and / or numbers.

  Moreover, in a set of comb teeth group, it is preferable that the positions of the vertices of the protruding pieces in two adjacent comb teeth are shifted at all the vertices, but the positions of the vertices of the protruding pieces partially overlap. May be.

  Hereinafter, the present invention will be described in more detail with reference to examples. However, the scope of the present invention is not limited to such examples.
