Patent Document 1 discloses a hair dyeing applicator in which a brush and a brush are provided upside down.

Japanese Utility Model Publication No. 4-81536

  Brushes are formed by bundling linear (hairy) members to form an application part, so the application part itself is more easily deformed than a brush or comb in which the application part is formed with a plurality of rod-shaped members, and the hairline, whiskers, etc. However, there was a problem in applicability because the hair cosmetic applied to the hair was removed more than necessary.

In this respect, if it is a brush or a comb, the hair cosmetic remains in the hair moderately, so that the applicability is good, but there is a problem that irritation to the skin is great.
The present invention has been made in view of these problems, and an object of the present invention is to provide a hair cosmetic applicator that has low skin irritation and good applicability.

Hair Hair cosmetic applicator of the present invention made in order to achieve the above object, a elongated member having flexibility, a plurality of rod-shaped extending in the extending direction of the tip at one end in the longitudinal direction An application portion having a member and a knob portion for pinching with a finger are provided, and the application portion and the knob portion are connected via a plate-like spatula portion having a thickness smaller than that of the knob portion.

  Here, the plate shape means a thin and flat shape, and includes a curved surface shape as well as a flat outer surface (surface intersecting the thickness direction). In addition, not only those having a constant thickness but also those close to a constant (for example, one of the outer surfaces is planar and the other is curved) are included.

  According to such a hair cosmetic applicator, the application part functions as a brush or a comb, so that the hair cosmetic can be applied to the hair, and the spatula part bends at that time, thereby stimulating the skin. Can be relaxed. And the hair cosmetics apply | coated to hair using the outer surface of a spatula part can be extended efficiently.

Specifically, For example, the ratio of the knob portion of the thickness to the thickness of the spatula portion may in the range of from 1.1 to 10. According to such a hair cosmetic applicator, the spatula portion can be favorably bent.

By the way, when such a hair cosmetic applicator is used, for example, with the application part facing upward, it is conceivable that the hair cosmetic flows from the application part. Therefore, For example, it may be a recess along the widthwise central portion of the grip portion in the longitudinal direction. According to such a hair cosmetic applicator, it is possible to prevent the hair cosmetic flowing to the knob portion from dripping from the outer side in the width direction of the knob portion. In addition, the finger can be easily picked by placing a finger in the recess.

On the other hand, example, may be from the opposite side of the knob portion sandwiching the knob portion of the spatula portion is formed as a thin plate-like shank thickness. According to such a hair cosmetic applicator, the hair cosmetic applied to the hair using the outer surface of the handle can be extended.

And, in such a hair cosmetic applicator, For example, the ratio of the knob portion of the thickness to the thickness of the handle portion may in the range of from 1.1 to 10. According to such a hair cosmetic applicator, the handle can be flexed satisfactorily.

Moreover, in such a hair cosmetic applicator, since the thickness of a handle | pattern part is thin, it is thought that it becomes difficult to hold | grip. Therefore, For example, has generally curved over the longitudinal direction, the knob portion may be inflated to bend inward. According to such a hair cosmetic applicator, it can be easily gripped with a sense similar to that of a thick member by gripping the curved inner surface of the knob portion and the curved outer surface of the handle portion. .

  In addition, regarding the configuration described above, the thickness of the knob portion is based on the thickness of the thickest portion (the most difficult portion to bend), and the thickness of the spatula portion and the handle portion is the thickness of the thinnest portion (the most flexible portion). It is preferable to use it as a reference in terms of operational effects.

It is a perspective view of the hair cosmetics applicator of embodiment. It is explanatory drawing of the external appearance shape of the hair cosmetics applicator of embodiment, (a) is a top view, (b) is a side view, (c) is a rear view. It is explanatory drawing of the side shape of the hair cosmetic applicator of a modification, (a) is what formed the groove part inside the curve of the spatula part, (b) is a thing of the shape where the spatula part swelled inside the curve. .

Embodiments to which the present invention is applied will be described below with reference to the drawings.
FIG. 1 is a perspective view of a hair cosmetic applicator 10 according to an embodiment. Moreover, FIG. 2 is explanatory drawing of the external appearance shape of this hair cosmetics applicator 10, (a) is a top view, (b) is a side view, (c) is a rear view.

  This hair cosmetic applicator 10 is for applying cream or liquid hair cosmetics such as hair coloring agents, depigmenting agents, hair deforming agents, etc. to hair (especially short hair such as hairline and hair). is there. Specifically, the hair cosmetic applicator 10 is a long plate-like member having flexibility, and is slightly curved as a whole in the longitudinal direction in a side view (FIG. 2B). The brush part 20 is formed in the end of the elongate direction. A knob 40 is formed at the center in the longitudinal direction, and the brush 20 and the knob 40 are connected via a spatula 30. Furthermore, a handle 50 is formed on the opposite side of the spatula 30 with the knob 40 interposed therebetween. In addition, these brush part 20, the spatula part 30, the knob part 40, and the handle | pattern part 50 are integrally molded with the synthetic resin.

  The knob part 40 is a part for pinching with a finger (for example, thumb and forefinger) when using the hair cosmetic applicator 10. This knob portion 40 has a shape in which the plate thickness bulges inward (downward in FIG. 2B) in a side view (thickness in the width direction is constant), and compared to the spatula portion 30 and the handle portion 50. The plate is thick. The thickness of the knob portion 40 (meaning the thickness of the thickest portion in the knob portion 40; the same applies hereinafter) is preferably in the range of 3.0 to 10.0 mm, and is 5.0 mm in this embodiment. .

  Further, the knob portion 40 is formed so that the width gradually decreases toward the center in the longitudinal direction in a plan view (FIG. 2A), and a plurality of (in this example, five in the constricted portion). ) Is formed over the entire circumference. Furthermore, the outer surface (curved outer surface) 42 of the knob portion 40 is formed with a recess 43 that is recessed in the center in the width direction along the longitudinal direction (see a partially enlarged view of FIG. 1).

  On the other hand, the spatula portion 30 is a flat plate-like portion having a rectangular shape (specifically, a shape in which the width gradually decreases from the knob portion 40 side toward the brush portion 20 side) in a plan view, and the plate thickness is constant. The plate thickness is smaller than that of the knob portion 40 and plays a role of alleviating irritation to the skin by bending when an external force is applied to the brush portion 20.

  In addition, it is preferable that the width | variety and thickness of the spatula part 30 are in the range of 15.0-25.0mm and 1.0-3.0mm, respectively, and, in this embodiment, a narrow part (brush part 20 side). The width and thickness are 18.5 mm and 1.7 mm, respectively, and the width and thickness of the wide portion (knob portion 40 side) are 20.0 mm and 1.7 mm, respectively. Here, the ratio of the width to the thickness of the spatula portion 30 (width / thickness) is preferably in the range of 6.0 to 25.0 (preferably 8.0 to 20.0). The narrow portion is 10.9 (= 18.5 / 1.7) and the wide portion is 11.7 (= 20.0 / 1.7). Moreover, in order to bend the spatula part 30 satisfactorily, the ratio of the thickness of the knob part 40 to the thickness of the spatula part 30 is in the range of 1.1 to 10.0 (preferably 2.0 to 8.0). In this embodiment, it is 2.94 (= 5.0 / 1.7).

  Further, the spatula portion 30 is suitable for extending the hair cosmetic applied to the hair because the outer surface (curved outer surface) 31 has a large area. Moreover, since the side surface 32 is formed linearly, it is easy to scoop off the hair cosmetics remaining on the mixing tray or the like.

  On the other hand, the brush part 20 has a flat base part 21 having a thickness greater than that of the spatula part 30 and a plurality of parts extending in the extension direction (longitudinal direction) of the tip from the plate thickness surface on the tip side of the base part 21. (In this embodiment, it is composed of 7 rods × 2 rows = 14 rod members 22, 22,...). In addition, it is preferable that the thickness of the base part 21 exists in the range of 3.0-7.0 mm, and is 4.5 mm in this embodiment. Moreover, in order to bend the spatula part 30 favorably, it is preferable that the ratio of the thickness of the base part 21 to the thickness of the spatula part 30 is in the range of 1.0 to 7.0. 65 (= 4.5 / 1.7).

  Further, the base portion 21 is bent inwardly with respect to the spatula portion 30. In addition, it is preferable that the bending angle of the base part 21 with respect to the spatula part 30 exists in the range of 100-170 degrees, and is set to 146 degrees in this embodiment.

  The rod-shaped members 22, 22,... Have the same shape and the same length and project in parallel with each other, and the tips are located on the same plane. Here, the rod-shaped member 22 at the end in the width direction is formed at the end in the width direction on the plate thickness surface of the base portion 21. That is, the widthwise ends of the rod-shaped member 22, the base portion 21, and the spatula portion 30 are formed in a straight line shape (without providing a step) in a plan view, and the hair cosmetic remaining on the mixing tray or the like is applied to the hair makeup. The side of the coating material applicator 10 is easy to scoop.

  Similarly, when viewed from the side, the rod-like member 22 is formed at the end in the thickness direction of the plate thickness surface of the base portion 21. That is, when the thickness direction ends of the rod-shaped member 22 and the base portion 21 are formed in a straight line shape (without providing a step) in a side view, and the hair cosmetic is applied to the hair on the outer surface 31 of the spatula portion 30. In addition, the hair cosmetics are not easily scraped off at the corners of the base 21.

  On the other hand, the handle part 50 is a part for allowing the hair cosmetic applicator 10 to be stably held by coming into contact with another finger or palm when the knob part 40 is pinched with a finger. Thus, it is formed in a rectangular plate shape (specifically, a shape in which the width gradually decreases from the knob portion 40 side toward the tip portion 51 side) (a slightly curved curved plate shape). Moreover, since the front-end | tip part 51 is narrower than the spatula part 30, the handle | pattern part 50 is suitable for extending the hair cosmetics apply | coated to the hair to a fine part. In particular, since the handle portion 50 has a constant plate thickness and is thinner than the knob portion 40, irritation to the skin is alleviated by bending when an external force is applied to the distal end portion 51 of the handle portion 50. The

  The width and thickness of the handle 50 are preferably in the range of 10.0 to 16.0 mm and 1.0 to 3.0 mm (width / thickness = 3.3 to 16.0), respectively. In the embodiment, the width and thickness of the narrow portion (tip side) are 10.5 mm and 1.5 mm, respectively, and the width and thickness of the wide portion (knob portion 40 side) are 15.0 mm and 1.5 mm, respectively. Moreover, in order to bend the handle part 50 satisfactorily, the ratio of the thickness of the knob part 40 to the thickness of the handle part 50 is preferably in the range of 1.1 to 10.0. In this embodiment, 3.33. (= 5.0 / 1.5).

  As described above, in the hair cosmetic applicator 10 of the present embodiment, the hair cosmetic is applied to the hair by the brush unit 20, so that the hair cosmetic applied to the hair like a brush is stripped more than necessary. It can be efficiently applied. In particular, since the brush part 20 is bent inwardly with respect to the spatula part 30, the application work can be performed in a natural manner without raising the arm as much as possible.

  Moreover, in this hair cosmetic applicator 10, since the brush part 20 and the knob part 40 are connected by the spatula part 30 whose plate | board thickness is thin compared with these, hair cosmetics are apply | coated to hair by the brush part 20. In this case, the hair cosmetic can be applied firmly while feeling moderate bending of the spatula portion 30, and the irritation to the skin can be alleviated. In particular, since the knob portion 40 is formed to be thicker than the spatula portion 30, the hair cosmetic applicator 10 does not bend as a whole, but the spatula portion 30 can be bent intensively. And the hair cosmetics apply | coated to hair using the outer surface of the spatula part 30 can be extended efficiently. Moreover, since the width direction edge part of the rod-shaped member 22, the base part 21, and the spatula part 30 is formed linearly by planar view, the hair which remained on the mixing tray etc. by using a linear part as a spatula Cosmetics can be easily scooped up.

  Moreover, in this hair cosmetic applicator 10, since it is curving as a whole in the longitudinal direction and the knob portion 40 swells inside the curve, the curved inner surface of the knob portion 40 and the handle portion 50 By gripping with the curved outer surface, it is possible to grip with the same feeling as a thick member even if the handle 50 itself is thin. Moreover, since the recessed part 43 is formed along the elongate direction in the width direction center part in the outer surface 42 of the knob part 40, the hair cosmetics which flowed to the knob part 40 drips from the width direction outer side of the knob part 40. Can be guided so that there is no. In addition, the knob 40 can be easily pinched by placing a finger in the recess. Further, the constricted portion 40 is formed with a constricted portion in a plan view, and since the plate thickness is thick, it can be stably held even when the side surface is pinched.

  Further, in this hair cosmetic applicator 10, since the handle 50 is narrower than the spatula 30 and thinner than the knob 40, the hair makeup is applied using the tip. The material can be efficiently extended to fine parts, and the skin irritation at that time can be alleviated.

  In this embodiment, the hair cosmetic applicator 10, the knob portion 40, the spatula portion 30, the handle portion 50, and the brush portion 20 are the hair cosmetic applicator, knob portion, spatula portion, and handle portion of the claims. And corresponding to the application part.

As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form, without being limited to the said embodiment.
For example, in the above embodiment, the brush portion 20 provided with two rows of rod-like members 22, 22,... Is exemplified as the application portion. On the contrary, it is also possible to use a rod-shaped member provided with only one row (comb).

  Moreover, in the said embodiment, although the thickness of the spatula part 30 is formed uniformly, it is not limited to this. For example, as shown in FIG. 3A, a groove 33 along the width direction may be formed on the curved inner surface of the spatula 30. With such a shape (in other words, a shape in which plate-like portions having different thicknesses are alternately connected along the longitudinal direction), the spatula portion 30 is more easily bent at the portion where the groove portion 33 is formed. be able to. On the other hand, as shown in FIG. 3 (b), the finger can be easily fixed to the spatula 30 by making the curved inner side of the spatula 30 bulge (the thickness in the width direction is constant). In addition, since the preferable range regarding the thickness of the spatula part 30 demonstrated by the said embodiment is related with the ease of bending of the spatula part 30, the thickness of the spatula part 30 is constant like FIG. 3 (a), (b). If not, the thickness of the thinnest part (the most flexible part) in the spatula part 30 may be regarded as the thickness of the spatula part 30. This also applies to the handle portion 50. If the thickness of the handle portion 50 is not constant, the thickness of the thinnest portion (the most flexible portion) of the handle portion 50 can be regarded as the thickness of the handle portion 50. Good.

Moreover, although the pattern part 50 formed what was formed in plate shape in the said embodiment, it is not limited to this, It can also be set as the shape with thickness other than plate shape.
Furthermore, in the said embodiment, although the synthetic resin was illustrated as a material of the hair cosmetic applicator 10, it is not limited to this, For example, it is also possible to use an elastomer.
