Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a brush suitable for applying hair cosmetics such as hair dyes to the entire hair.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there has been known a hair cosmetic application brush in which a brush portion in which comb teeth formed with hair cosmetic discharge holes such as a hair dye are arranged in a hair cosmetic container is mounted. In this case, a liquid passage is formed in the comb teeth to communicate the cosmetic container and the comb discharge holes. Therefore, according to this hair cosmetic application brush, the hair cosmetic is discharged from the comb tooth discharge holes by pressing the hair cosmetic container, and the hair is applied while the hair cosmetic is applied to the hair. Therefore, the hair cosmetic can be easily applied to the hair as compared with the case where the container for containing the hair cosmetic and the brush are separate.
[0003]
[Problems to be solved by the invention]
However, in the conventional hair cosmetic application brush, the hair cosmetic is held exclusively in the vicinity of the comb teeth discharge hole and is not held between the entire comb teeth, so the hair cosmetic is sufficiently held between the comb teeth, It cannot be applied efficiently to the entire hair.
[0004]
In addition, depending on the type of dye used in the hair dye, it is necessary to avoid as much as possible on the scalp, but there is a conflicting demand to dye the hair firmly to the root. As a result, brushes for applying hair cosmetics should prioritize dyeing to the base of the hair over prevention of the scalp, or prevent the scalp from being dressed at the expense of dyeing of the base of the hair. It does not satisfy both the prevention of dressing on the scalp and the dyeing to the base of the hair.
[0005]
On the other hand, the present invention can apply hair cosmetics such as hair dyes to the entire hair including the roots of the hair with a good feeling of combing, and the hair cosmetics are also applied to the scalp. It aims at providing the brush for hair cosmetics application which can be reduced.
[0006]
[Means for Solving the Problems]
The present inventor, instead of providing a hair cosmetic application brush in which a brush portion made of comb teeth for discharging hair cosmetic is attached to a container for storing hair cosmetic, is provided with a liquid passage and a discharge hole in the comb teeth. If the slit-shaped opening is provided, it is possible to hold the hair cosmetic material between the entire comb teeth, and if the convex portion is formed between the comb teeth on the base surface of the brush portion, the hair is combed. It has been found that the cosmetic can be prevented from being pushed out unnecessarily between the comb teeth, thereby making it easier to hold the hair cosmetic between the comb teeth and efficiently applying the hair cosmetic to the entire hair.
[0007]
That is, the present invention relates to a brush part in which a plurality of comb teeth having a hair cosmetic discharge opening are arranged, and a liquid passage for connecting the hair cosmetic discharge opening to the hair cosmetic container. Is composed of a connecting portion formed inside, the outer shape of the comb teeth is wide on the base side of the brush portion, and is narrow on the tip side of the comb teeth, and the discharge opening for the hair cosmetics has a comb-tooth shape. Provided is a hair cosmetic application brush that has a slit shape extending from the brush portion base surface side end portion to the vicinity of the tip portion of the comb teeth, and has convex portions formed between the comb teeth of the brush portion base surface.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same code | symbol represents the same or equivalent component.
[0009]
FIG. 1 is a perspective view of the hair cosmetic application brush 1 according to an embodiment of the present invention (FIG. 1A), a longitudinal sectional view of the brush portion (FIG. 1B), and a transverse sectional view of the brush 1 (C).
[0010]
The hair cosmetic application brush 1 includes a container 2, a brush part 4 in which a plurality of comb teeth 3 are arranged, and a connecting part 5 that connects the container 2 and the brush part 4.
[0011]
The container 2 contains hair cosmetics such as hair dyes and hair styling agents, and is made of a flexible material that can extrude the hair cosmetics by pressing.
[0012]
As the flexible material, for example, a container composed of a flexible outer layer and an inner layer that is detachably laminated on the outer layer as disclosed in JP 2000-16470 is used. It is preferable that air is introduced between the outer layer and the inner layer after pressing and the inner layer is peeled and contracted and deformed while restoring the outer layer to the shape before pressing. This eliminates the need for a dip tube and allows the container 2 to be used either upright or inverted. In addition, the container 2 may discharge the hair cosmetic as an aerosol.
[0013]
The outer shape of the comb teeth 3 is wide on the brush portion base surface 6 side, and has a narrow triangular shape on the tip portion 7 side of the comb teeth 3. Here, the external shape of the comb teeth 3 does not mean that the planar shape of the comb teeth 3 is a triangle in a strict sense. As shown in FIG. 1C, the opening angle θ1 on the tip 7 side of the comb teeth 3 can be made smaller than the opening angle θ2 on the brush base surface 6 side. Thus, by making the opening angle θ1 of the tip 7 small and making the tip 7 of the comb teeth 3 narrow, it becomes easier to comb the hair, and by widening the brush base surface 6 side, The retainability of hair cosmetics can be improved. Moreover, it is good also considering the front-end | tip part 7 of the comb tooth 3 as the round shape which gave roundness. Thereby, a feeling of combing can be improved.
[0014]
In the comb tooth 3, a hair cosmetic discharge opening 8 is formed in a slit shape from the brush base surface 6 side end of the comb tooth 3 to the vicinity of the tip 7 of the comb tooth 3.
[0015]
As shown in FIG. 3 (c), a liquid passage 9 and a discharge hole 10 that pass through the inside of the comb tooth are formed in the comb tooth 3 </ b> Y, and the hair cosmetic extruded from the container passes through the liquid passage 9 and is a discharge hole. Since the hair cosmetic material must pass through the thin liquid passage 9 when it is discharged from 10, considerable force is required to discharge the hair cosmetic material, but the slit-shaped opening 8 is formed. By doing so, it becomes possible to discharge hair cosmetics with less force, and it becomes possible to deal with a wide range of agents including high-viscosity hair cosmetics. Moreover, when the discharge hole 10 is formed as shown in FIG. 3C, the hair cosmetic is brushed between the comb teeth while the comb 3Y is moved in the direction of the arrow with respect to the hair H and the hair H is combed. Since it is hard to hold | maintain in the wide area | region of the base surface 6 side, and it hold | maintains exclusively in the area | region A around the discharge hole 10, the application efficiency of hair cosmetics becomes low.
[0016]
On the other hand, when the slit-shaped opening 8 is formed in the comb tooth 3 from the brush part base surface 6 side end to the vicinity of the tip part 7 of the comb tooth 3 as described above, the hair cosmetic discharged from the opening 8 Spreads in the lateral direction (in the direction of combing hair) and is held throughout the comb teeth, so that the hair cosmetic can be efficiently applied. Further, by forming the slit-shaped opening 8 instead of the discharge hole 10 shown in FIG. 3C, the comb teeth 3 can be easily cleaned.
[0017]
In the present invention, the fact that the hair cosmetic discharge opening 8 is formed in the vicinity of the tip 7 of the comb tooth 3 means that the distance L1 between the tip of the opening 8 and the tip of the comb 3 is L1. Is 2.5 mm or less. This distance L1 is 0.5-2. From the balance that the hair cosmetic is held in the entire region between the comb teeth 3 and the hair cosmetic is prevented from adhering to the scalp. It is preferably 0 mm.
[0018]
The shape of the opening 8 is preferably changed as appropriate depending on the viscosity of the hair cosmetic applied to the brush. For example, when the viscosity of the hair cosmetic is high, it may have a substantially triangular shape that is wide on the brush base surface 6 side and narrow on the tip 7 side of the comb teeth 3 and is substantially similar to the outer shape of the comb teeth 3. preferable. Moreover, when the viscosity of hair cosmetics is low, it is preferable to narrow the width | variety of the opening part 8 in the brush part base surface 6 side rather than the case where the viscosity of hair cosmetics is high, and it is an opening part from the brush part base surface 6 side. It is good also as the substantially same width to the vicinity of the front-end | tip of 8. By making the opening 8 in a shape according to the viscosity of the hair cosmetic and the like in this way, the application efficiency of the hair cosmetic can be further improved.
[0019]
In the present invention, the above-described openings 8 are preferably provided in all the comb teeth 3. Thereby, since hair cosmetics can be discharged between all the comb teeth 3, and it can apply | coat by holding hair cosmetics in the wide area | region between each comb teeth, the efficiency of an application | coating operation | work can be improved.
[0020]
Between the comb teeth 3 of the brush portion base surface 6, convex portions 11 protruding toward the tip portion 7 side of the comb teeth are formed. When the convex portion 11 is not formed between the comb teeth 3X as shown in FIG. 3B, the comb teeth 3X are held between the comb teeth 3X while combing the hair H in the direction of the arrow and combing the hair. A part of the hair cosmetics is pushed out to the outer region B between the comb teeth 3X, and the secondary contamination problem that the pushed out hair cosmetics adhere to unnecessary parts is likely to occur. By forming the convex portion 11 between the comb teeth 3 as shown in a), a part of the hair cosmetic is pushed out unnecessarily between the comb teeth 3 while combing the comb teeth 3 in the direction of the arrow. This can be prevented, and the amount can be held in the regions C and D in the comb teeth 3. Therefore, it is possible to prevent the hair cosmetic material from adhering to unnecessary portions.
[0021]
The size of the protrusion 11 is such that the height L2 from the end of the brush base surface 6 is 2/10 to 3.5 / 10 of the effective length L3 of the comb tooth 3, and the width L4 of the top of the protrusion 11 is The width L5 of the brush portion base surface 6 is preferably 1/10 to 3.5 / 10, and the top width L4 is particularly preferably 1 mm or more. When the height L2 of the convex portion is too low, there is no effect of forming the convex portion 11, and when it is too high, the region where the hair cosmetic material can be held between the comb teeth 3 becomes excessively narrow. On the other hand, if the width L4 of the top portion of the convex portion 11 is too small, the convex portion 11 breaks while combing the hair due to insufficient strength of the convex portion 11, and if the width L4 is too large, the hair cosmetic is applied between the comb teeth 3. The regions C and D that can be held (see FIG. 3A) become excessively narrow.
[0022]
If the gap L6 between the comb teeth 3 is too narrow, it is suitable for applications such as partial dyeing, but it is not suitable for application of hair cosmetics to the entire hair, so it should be 1.5 to 2.5 mm. Is preferred.
[0023]
On the other hand, the connecting part 5 has a hair cosmetic liquid passage 12 formed therein, and connects the discharge opening 8 formed in the comb teeth 3 and the container 2, and the hair in the container 2. The cosmetic can be discharged from the comb teeth 3. The connecting portion 5 may be formed integrally with the container 2, but may be a separate member. Moreover, as shown in FIG. 2, it is preferable that the connecting part 5 and the brush part 4 be detachable from the viewpoint of molding of the member.
[0024]
A branch passage 13 is provided at the end of the liquid passage 12 on the brush portion 4 side, while a communication passage 14 is provided below the brush base surface 6 to communicate each discharge opening 8 to branch the connecting portion 5. The path 13 and the communication path 14 below the brush base surface 6 may be communicated with each other, and as shown in FIG. 4, the branch path 13 corresponds to the formation position of the discharge opening 8 of each comb tooth 3. And the branch passage 13 and the discharge opening 8 may be directly communicated with each other. By providing the branch path 13 in this way, it becomes possible to create a flow of the hair cosmetic toward the tip 7 of the comb teeth 3 in the openings 8 of all the comb teeth 3, and a uniform amount of hair makeup. The material can be discharged. On the other hand, when hair cosmetics are sent directly from the liquid passage 12 of the connecting portion 5 to the openings 8 of the comb teeth 3, the hair cosmetics are uniformly fed from the openings 8 of all the comb teeth 3. Difficult to discharge.
[0025]
In addition, in order to make the amount of the hair cosmetic discharged from the discharge opening 8 equal in all the comb teeth 3, the degree of opening of the branch path 13 increases as the distance from the mouth of the container 2 increases as shown in FIG. It is preferable.
[0026]
As mentioned above, although the brush for hair cosmetics application | coating of this invention was demonstrated based on drawing, this invention can take a various aspect further.
[0027]
For example, in order to make the amount of the hair cosmetic discharged from the opening 8 equal for all the comb teeth 3, the length L7 of the opening 8 from the brush portion base surface 6 side to the tip 7 of the comb teeth 3 is set. The comb teeth 3 that are farther from the container 1 may be longer (that is, the height L2 of the convex portion is shorter), or the width of the opening from the brush base surface 6 side to the tip of the comb teeth 3 may be The comb teeth 3 farther away from the container 1 may be made wider.
[0028]
【The invention's effect】
According to the hair cosmetic application brush of the present invention, it is possible to hold the hair cosmetic composition between the entire comb teeth and apply it efficiently to the entire hair. For this reason, even if it is long hair, it becomes possible to perform the whole application of hair cosmetics easily. Moreover, according to this invention, adhesion of the hair cosmetics to a scalp can be reduced, and a favorable combing feeling can be obtained.
