  As an applicator currently used for applying mascara to eyelashes, a spiral applicator having a spiral groove cut at the end of a cylinder as in Patent Document 1, such as Patent Documents 2 to 4 There are scissors-like applicators and comb-like applicators as disclosed in Patent Documents 5-7.

Japanese Examined Patent Publication 54-19442 JP-A-9-238740 Special table 2003-515410 gazette Special table 2003-521982 gazette JP 2001-145515 A JP 2001-231627 A JP 2003-259914 A

  Recently, mascara containing fibers has been introduced to increase the volume and length of eyelashes, but any of the above-mentioned applicators are difficult to apply evenly, and the eyelashes stick together. In particular, in the case of containing fibers, there are problems such as non-uniform (unevenness) adhesion direction of the fibers, and the comb-like applicator does not adhere to the fibers.

  In view of such prior art, the present invention can apply a suitable amount of a cosmetic such as mascara to the eyelashes and uniformly distribute the eyelashes so that the eyelashes do not stick to each other. Provides an applicator for eyelashes that can align the fiber attachment direction and prevent unevenness.

  In order to solve the above-mentioned problems, the applicator for eyelashes according to the present invention has a groove having a predetermined length in the application direction (direction in which the eyelashes are stroked) and capable of holding fibers in the cosmetic material aligned in the application direction. , And having a large number in parallel at a constant pitch.

  If the length of the groove corresponds to around 6 mm of the average length of the eyelashes and is 3 to 7 mm, the eyelashes can be kept firmly and lifted up, and it is optimal for neatly dispersing and adjusting. It is also suitable to form such groove depths in the range of 0.3-2 mm and pitches in the range of 0.4-1 mm, so that the fibers in the cosmetic can be reliably aligned and held. ,preferable. According to the applicator for eyelashes, when used for a mascara containing a fiber having a thickness of 0.5 to 20D (denier) and a length of 0.3 to 3.0 mm, it is uniform and smooth, and the direction of fiber attachment Can be applied evenly.

  In such an applicator, when the grooves are formed so that the cross-sectional shape is V-shaped, the pitch is set to 0.6 mm, and the depth is set to 0.7 mm, the eyelash holding power and the amount of cosmetics included. To achieve the optimum finish.

  Further, a protrusion formed between adjacent grooves is longer in the application direction than at least the length of the rod in which the groove is formed in the application direction, and the rod has a predetermined length in the application direction. A plurality of protrusions projecting outward from the protrusion are formed, and are configured to have a comb-like shape as a whole, and the protrusion pitch and groove pitch are both 0.5 to 1.0 mm. It is configured to eliminate the fact that the pitch of the part is too narrow and cannot be broken without entering the eyelashes, or that there are many bundles of fibers in the cosmetics or cosmetics and cannot be broken.

  When the length of the comb-like protruding portion protruding from the rod having a predetermined length in the application direction is set to 0.3 to 2.0 mm, the cosmetic and the cosmetic are applied at the time of applying the cosmetic. It is preferable that the eyelashes, which are bundled and bundled with the fibers inside, can be unwound one by one.

  According to the applicator for eyelashes of the present invention, by providing grooves of a predetermined length in parallel at a constant pitch, the eyelashes are securely held at the length of the grooves, and the eyelashes are dispersed neatly at a constant pitch. Can be aligned so that they do not stick to each other. Further, by appropriately adjusting the length and depth of the groove, the amount of cosmetics to be retained can be adjusted, and an appropriate amount can be easily and uniformly applied. Furthermore, since the fibers in the cosmetic can be aligned and held in the application direction (that is, along the eyelashes) by the grooves having a predetermined length, the unevenness of the fibers is prevented and the adhesion direction is aligned. It becomes possible to apply uniformly.

  Also, even if the eyelashes stick together due to cosmetics or fibers in the cosmetics and become lumps or bundles, they are formed longer than the length of the rod application direction and protruded There is an effect that it is possible to comb and unravel the eyelashes by a comb-like rod composed of a plurality of protrusions.

  1 to 3 show and describe an embodiment of the eyelash applicator of the present invention.

  The applicator for eyelashes (1) of this example cuts the front-end | tip part of a cylindrical rod (2) flatly, forms a plane part (3), and cross-sectional shape is V character in this plane part (3). It has a saw-tooth structure in which a large number of groove-like grooves (4) are formed in parallel. The flat portion (3) is formed from the tip of the rod (2) to 10 to 30 mm in correspondence with the width of the eye. The range of the flat portion (3) is the formation width of the groove (4). However, the present invention is not limited to this, and it is of course possible to use an example in which the entire rod is prismatic and one surface thereof is used as a flat surface.

  The groove (4) can be formed with a length L = 3 to 7 mm in the application direction indicated by the arrow A perpendicular to the axis of the rod (2). In the case of this example, since the average of the eyelashes is around 6 mm, L = 3.5 mm is set so that the eyelashes can be kept firmly and lifted. The pitch P and depth D are preferably in the range of pitch P = 0.4 to 1 mm and depth D = 0.3 to 2 mm, considering the holding power of eyelashes and the mascara. As shown in Fig. 2, when the pitch P was set to 0.6 mm and the depth D was set to 0.7 mm, an optimum result was obtained in terms of including the eyelash paste and the mascara. That is, if the pitch is too small and too shallow, the glue of the eyelashes is poor and the amount of mascara is too small. On the other hand, if the pitch is too large and deep, the mascara will be attached too much, resulting in a finished finish.

  When such an eyelash applicator (1) is used to apply mascara containing fibers having a thickness of 0.5 to 20D (denier) and a length of 0.3 to 3.0 mm, the fibers are used as grooves (4 ) And can be neatly aligned along the application direction A. Then, as shown in FIG. 3, when the applicator (1) is lifted in the application direction A along the eyelashes, the eyelashes are held in the grooves (4) and are dispersed and aligned one by one. It is lifted up while being done. Moreover, an appropriate amount of mascara is uniformly applied depending on the length L of the groove (4), and a clean finish can be obtained. At that time, fibers held in the groove (4) and aligned in the application direction A adhere to the eyelashes uniformly, and an appropriate amount is applied uniformly.

  The example of the applicator for eyelashes which processed the plane part (3) so that it may be easier to use to FIG. That is, the flat surface portion (30) of the eyelash applicator shown in FIG. 4a is curved in the longitudinal direction of the applicator according to the curve of the eyelid, and a groove (4) similar to the above is formed here. As shown in the figure, the flat surface portion (30) may be concave according to the curve when the eyelid is closed, or may be convex according to the curve when the eyelid is opened. Also, the flat portions (31) and (32) of FIGS. 4b and 4c are inclined at a predetermined angle θ, preferably 10 to 45 °, with respect to the axis (2a) of the rod (2). Is lower than the axis (2a), and the plane portion (32) is higher than the axis (2a). These modifications can be selected and used according to preference.

  5 to 9 show an embodiment of the eyelash applicator according to one modification of the present invention. However, the description of the same configuration as the above embodiment is omitted.

  The applicator for eyelashes (5) of this example cuts the front-end | tip part of a cylindrical rod (6) flatly, forms a plane part (7), and cross-sectional shape is substantially V in this plane part (7). It has a sawtooth structure in which a large number of letter-shaped grooves (8) are formed in parallel. The flat portion (7) is formed from the tip of the rod (6) to 10 to 30 mm in correspondence with the width of the eye. The range of the flat portion (7) is the formation width of the groove (8). However, the present invention is not limited to this, and an example in which the entire rod is formed in a prismatic shape and one surface thereof is used as a flat portion is, of course, similar to the above embodiment.

  Further, between the adjacent substantially V-shaped grooves (8), protrusions (9) having a Λ-shaped cross section are formed. Each of the juxtaposed ridges (9) is formed longer than the length of the rod (6) in the application direction, and protrudes from the flat surface (7) in the application direction ( 10). The projecting portion (10) is formed with a length from the root position of the flat surface portion (7) to the tip thereof being 0.3 to 2.0 mm, and is tapered from the root position to the tip position. Of course, the protrusion does not necessarily have to be tapered, but it is preferable to taper the protrusion so that the protrusion can be easily passed through lashed eyelashes or cosmetics or fibers in cosmetics. In addition, the length from the base to the tip of the protruding portion 10 formed to protrude outward on both sides of the flat portion (7) may be changed on both sides.

  In the eyelash applicator (5) provided with the protrusion (10) as in this example, as shown in FIGS. 4a to 4c, the rod (6) has a predetermined axis as shown in FIGS. Needless to say, the angle θ can be appropriately selected.

  In the eyelash applicator 5 configured as described above, when the pitch of the grooves (8) and the pitch of the protrusions (10) were variously changed and used, the results shown in FIG. 10 were obtained. According to this result, if the pitch of the groove (8) or the protrusion (10) is too narrow, it is difficult to comb the eyelashes between the protrusions (10). It has been shown that if it is too much, the cosmetics and the fibers in the cosmetics will become too lumpy or bundled, making it unprofitable. Therefore, it is preferable that the pitch of the groove (8) and the pitch of the protrusion (10) are both 0.5 to 1.0 mm, more preferably both the pitch of the groove (8) and the pitch of the protrusion (10) are both. The thickness is 0.8 mm.
