Description

[Technical Field]

[0001] The present disclosure relates to an applicator brush. [Background technology]

[0002] As an application brush for applying a substance such as a hair dye to hair, an application brush having a brush base connected to a grip and a group of protrusions protruding from the brush base is known (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-6793 Summary of the Invention [Problem to be solved by the invention]

[0004] With the above-described applicator brush, when the application material is placed on the brush base and the same area of ​​hair is combed several times, the application material that was applied before the hair is scraped off by the brush teeth as the brush passes and reattaches to the brush base. In this case, the application material that reattaches to the brush base accumulates on the back surface of the brush base (the side opposite the hair), and if the amount of application material accumulates beyond the allowable amount, it may fall from the brush base onto the floor or the like, causing stains. Therefore, the above-described conventional application brush still has room for improvement in this respect.

[0005] Therefore, an object of the present disclosure is to provide a new application brush that can suppress the accumulation of application material on the back surface of the brush base. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0015] As shown in Figures 1 to 3, in one embodiment of the present disclosure, an application brush 100 comprises a handle 10 that extends from the base end toward the tip and is held by the user, a brush base 20 that is connected to the tip of the handle 10 via a connecting portion 12, a plurality of main brush teeth 30 that protrude downward from the underside of the brush base 20 or that protrude downward and in a direction slanting outward in the left and right directions, a plurality of side comb teeth 40 that protrude outward in the left and right directions from the left and right ends of the brush base 20, a plurality of inclined brush teeth 50 that protrude downward from the underside at the tip of the brush base 20 in a direction slanting toward the tip, and a tip comb tooth 60 that protrudes toward the tip from the tip surface of the brush base 20.

[0016] In this specification, claims, and drawings, the downward direction of the application brush 100 is the downward direction in FIG. 1 (positive Z direction), which is the side on which the main brush teeth 30 and the like that come into contact with hair H (see FIG. 4) are provided. The upward direction of the application brush 100 is the upward direction in FIG. 1 (negative Z direction), which is the opposite direction from hair H. The tip direction of the application brush 100 is the left direction in FIG. 1 (positive X direction), and the base end direction of the application brush 100 on which the grip portion 10 is provided is the right direction in FIG. 1 (negative X direction). The left-right direction of the application brush 100 is the direction perpendicular to the plane of the paper in FIG. 1 (direction Y).

[0017] The accompanying drawings of the present disclosure are drawn to equal scale in the up-down direction (Z direction), tip-to-base direction (X direction), and left-to-right direction (Y direction), and the aspect ratio of the application brush 100 in the drawings represents the aspect ratio of the application brush 100 of one embodiment of the present disclosure. However, the configuration, shape, dimensional ratio, etc. of the application brush 100 in the accompanying drawings are merely one embodiment of the present disclosure. The present invention should be construed based on the wording of the claims, and is not limited to the configuration, shape, dimensional ratio, etc. shown in the drawings.

[0018] As shown in FIG. 3, the brush base 20 has a generally rectangular shape with rounded corners in a plan view. As shown in FIG. 2, a plurality of main brush teeth 30 are provided on both left and right sides of the underside, extending downward and sloping outward in the left-right direction (see FIG. 4, etc.). As shown in FIG. 2, the main brush teeth 30 extend downward and sloping outward in the left-right direction from positions near the left and right ends of the underside of the brush base 20, excluding the holding portion 25 provided in the left-right center for holding the object C, and surround the holding portion 25 from both left and right sides. The main brush teeth 30 are provided in a staggered pattern in three rows in the left-right direction at positions near the left and right sides of the brush base 20. At the base end of the brush base 20, the main brush teeth 30 are provided in a staggered pattern at all left-right positions, surrounding the holding portion 25 from the base end side.

[0019] In this way, by arranging the multiple main brush teeth 30 in a staggered pattern, the hair H can be passed between the staggered main brush teeth 30, making it easier to apply the application material C to the hair H.

[0020] 4, the underside of the brush base 20 has a curvature that convexes downward in the left-right direction, and each of the multiple main brush teeth 30 extends in a direction perpendicular to the underside of the brush base 20. As a result, the main brush teeth 30 located near the left-right ends of the brush base 20 extend downward and inclined outward in the left-right direction, while the main brush teeth 30 located in the center in the left-right direction extend downward. By having a curvature that convexes downward, the angular precision required when bringing the main brush teeth 30 of the application brush 100 into contact with the scalp or the like can be relaxed, and the pressing force that the main brush teeth 30 exert on the scalp can be reduced.

[0021] The upper surface of the brush base 20 has roughly the same curvature as the lower surface (see FIG. 4), but is provided with reinforcing edges 22 that stand upright at the left and right ends. The reinforcing edges 22 effectively prevent application material C adhering to the brush base 20 from going over the reinforcing edges 22 and wrapping around to the back surface of the brush base 20 (the surface opposite the hair H, which is the top surface in this embodiment) and accumulating thereon. As shown in FIG. 4, application material C adhering to the brush base 20 is held between the main brush teeth 30 arranged at the left and right ends and the multiple side comb teeth 40 extending outward in the left and right directions from the reinforcing edges 22, making it difficult for application material C to wrap around to the back surface of the brush base 20.

[0022] In this embodiment, as shown in Fig. 3, the reinforcing edge portions 22 are provided not only on the left and right ends of the brush base 20 but also on the tip and base ends of the brush base 20. In other words, the reinforcing edge portions 22 are formed along the periphery of the brush base 20 in a plan view. This configuration makes it possible to prevent the object C from wrapping around to the back surface from not only the left and right ends of the brush base 20 but also the tip and base ends. Furthermore, the brush base 20 can be made lighter while increasing its strength.

[0023] 2 to 4, a plurality of side comb teeth 40 are provided at the left and right ends of the brush base 20, protruding horizontally outward in the left and right direction from the reinforcing edge portion 22. The side comb teeth 40 are arranged so that the pitch in the direction from the base end (right end in FIG. 2) to the tip end (left end in FIG. 2) of the brush base 20 is smaller than the smallest pitch between the main brush teeth 30. In addition, the diameter of the base end (the inner end in the left and right direction connected to the brush base 20) of the side comb teeth 40 is smaller than the smallest diameter of the base end (the upper end connected to the brush base 20) of each of the main brush teeth 30.

[0024] With this configuration, the relatively viscous application material C adhering to the brush base 20 cannot pass between the side comb teeth 40, and is instead held in the area between the main brush tooth 30 at the left and right ends and the side comb teeth 40, as shown in Figure 4. This effectively prevents the application material C that has been applied to the hair H from adhering to the brush base 20 again and accumulating on the back surface of the brush base 20. Furthermore, the application material C adhering to the side comb teeth 40 can be used to efficiently apply the application material to the hairline of the hair H with precision.

[0025] The cross-sectional shape of each side comb tooth 40 is not limited to the circular shape (pin shape) shown in Fig. 1 etc., but may be an elliptical shape or the like. Also, each side comb tooth 40 may be a flat plate having a cross section of a rectangular shape, a track shape or the like. The same applies to the multiple end comb teeth 60 described later.

[0026] The tip end of the brush base 20 (the left end of the brush base 20 in FIGS. 1 and 2) is provided with a plurality of inclined brush teeth 50 that protrude downward from the underside of the brush base 20 in a direction inclined toward the tip end (leftward in FIGS. 1 and 2). As shown in FIGS. 1 and 2, the plurality of inclined brush teeth 50 are arranged at a shorter pitch and higher density than the plurality of main brush teeth 30, and each inclined brush tooth 50 is arranged so that the diameter at its base end (the base of each brush tooth) is smaller than that of each main brush tooth 30. The tip end of each inclined brush tooth 50 extends to a tip end position that is substantially the same as the tip end of the brush base 20. Note that the tip end of each inclined brush tooth 50 may be arranged to protrude further toward the tip end than the tip end of the brush base 20.

[0027] By using the above-described plurality of inclined brush teeth 50 that protrude toward the tip, it is possible to effectively apply the substance C to fine areas such as the hairline of the hair H. In this embodiment, the plurality of inclined brush teeth 50 surround the holding portion 25 that holds the substance C from the tip side.

[0028] A plurality of tip comb teeth 60 protruding in the tip direction (left direction in FIGS. 1 and 2) are provided on the tip surface (left end surface in FIG. 1) of the brush base 20. In this embodiment, as shown in FIG. 2, the tip comb teeth 60 are provided at substantially the same pitch as the side comb teeth 40, and the diameter of the base end (the root of each tip comb tooth 60) is also substantially the same as the diameter of the base end (the root of each side comb tooth 40) of the side comb teeth 40. In this embodiment, the tip surface of the brush base 20 has a curvature that is convex toward the tip direction in the bottom view shown in FIG. 2 and the plan view shown in FIG. 3, and each tip comb tooth 60 of the multiple tip comb teeth 60 extends perpendicular to the tip surface. Therefore, as shown in FIG. 2, the tip comb teeth 60 near the left and right ends extend at a slight incline outward in the left and right direction toward the tip.

[0029] By using the above-described plurality of tip comb teeth 60 that protrude toward the tip, the material C can be effectively applied to fine areas such as the hairline of the hair H. Furthermore, the relatively viscous material C that adheres to the brush base 20 cannot pass through between the plurality of tip comb teeth 60. Therefore, it is possible to effectively prevent the material C that has been applied to the hair H from adhering to the brush base 20 again and accumulating on the back surface of the brush base 20 from the tip side.

[0030] A grip portion 10 is provided on the base end side (the right side in Figs. 1 to 3) of the brush base 20 so that the user can grip the application brush 100. As shown in Figs. 2 and 3, the grip portion 10 has a generally rectangular shape in plan view, and includes a top wall 10c, side walls 10a hanging down from the left and right ends of the top wall 10c, a base end wall 10b hanging down from the base end of the top wall 10c, and a hollow portion 10h below the top wall 10c.

[0031] As shown in Fig. 3 etc., the width of the grip part 10 in the left-right direction gradually decreases toward the tip, and as shown in Fig. 1, the grip part 10 is connected to the brush base 20 via a connecting part 12 that slopes downward toward the tip. With this configuration, the brush base 20 can be made to protrude downward (toward the hair H) relative to the grip part 10, which effectively prevents the user's hands holding the grip part 10 from touching the hair H and causing the application substance C to adhere to the hair H.

[0032] In this embodiment, application brush 100 is a brush for applying, for example, a two-component hair dye to scalp hair. However, application brush 100 is not limited to this, and may be configured to be suitable for applying to hair H other than scalp hair, or for applying a hair dye other than a two-component hair dye, or for applying an object C other than a hair dye.

[0033] In this embodiment, the application brush 100 is a one-piece molded product made of synthetic resin. The synthetic resin from which the application brush 100 is made is not particularly limited, and examples thereof include polyolefins such as polypropylene and polyethylene, and polyesters such as polyethylene terephthalate.

[0034] When using the applicator brush 100 configured as described above, the user grasps the handle 10, holds the object C to be applied in the holder 25, presses the applicator brush 100 against the scalp, and moves it in the direction of combing the hair H (to the right in FIG. 4 ), thereby applying the object C, such as a hair dye, to the hair H. At this time, the holder 25 can hold an amount of object C to be applied that corresponds to the width of the holder 25 and the protruding heights of the main brush tines 30 and inclined brush tines 50.

[0035] When the application brush 100 is pressed against the scalp and moved in the direction of the white arrow in Fig. 4, the substance C held in the holder 25 is applied to the hair H. When the user combs the same area of ​​the scalp several more times to blend the substance C into the hair H, as shown in Fig. 4, the substance C that was applied to the hair H first is scraped off by the main brush teeth 30 and the like as they pass by, and adheres to the brush base 20 again.

[0036] The applied material C that reattaches to the brush base 20 accumulates on the outer surfaces of the main brush teeth 30 at the end of the application brush 100 in the direction of travel, but applied material C with a viscosity above a certain level has difficulty moving upward through the gaps between the side comb teeth 40, and instead accumulates and remains in the area between the main brush teeth 30 and the side comb teeth 40 (FIG. 4). Furthermore, even if the applied material C slightly passes over the side comb teeth 40, the provision of the reinforcing edge 22 makes it difficult for the applied material C to pass over the reinforcing edge 22 and enter the center in the left-right direction. This configuration effectively prevents the applied material C that reattaches to the brush base 20 from wrapping around and accumulating on the back surface of the brush base 20 (the surface opposite the hair H) or from falling from the brush base 20 onto the floor or the like, causing stains.

[0037] Furthermore, the application material C accumulated in the region between the main brush teeth 30 and the side comb teeth 40 at the end of the application brush 100 in the direction of travel is caught by hair H that subsequently passes through this region, and is again applied to the hair H. Therefore, the application material C can be effectively utilized.

[0038] As described above, the application brush 100 according to this embodiment is configured to include a grip portion 10 held by a user, a brush base 20 connected to the tip of the grip portion 10, multiple main brush teeth 30 that protrude downward from the underside of the brush base 20 or that protrude downward and inclined outward in the left-right direction, and multiple side comb teeth 40 that protrude outward in the left-right direction from the left-right end of the brush base 20. With this configuration, when a user combs the same area of ​​their scalp several times to blend the application material C into their hair H, the application material C that was applied to the hair H first adheres to the brush base 20 again and accumulates and is stored in the area between the main brush teeth 30 and the side comb teeth 40 at the end of the application brush 100 in the direction of travel. This effectively prevents the application material C that re-adheres to the brush base 20 from accumulating on the back surface of the brush base 20 (the surface opposite the hair H) or from falling from the brush base 20 onto the floor or other surfaces, causing soiling.

[0039] In this embodiment, the pitch between the side comb teeth 40 in the direction from the base end to the tip end of the brush base 20 is configured to be smaller than the smallest pitch between the main brush teeth 30. By adopting such a configuration, it is possible to make it difficult for the application material C that accumulates and accumulates in the area between the main brush teeth 30 and the side comb teeth 40 to go over the side comb teeth 40 and wrap around to the back surface of the brush base 20.

[0040] In this embodiment, the diameter of the base end of each of the side comb teeth 40 is configured to be smaller than the smallest value of the diameter of the base end of each of the main brush teeth 30 of the multiple main brush teeth 30. By adopting such a configuration, the side comb teeth 40 can be used to efficiently apply the agent to the hairline of the hair H, etc.

[0041] Furthermore, in this embodiment, the brush base 20 is further configured to have a plurality of inclined brush teeth 50 that protrude downward from the underside of the tip of the brush base 20 in a direction inclined toward the tip. By adopting such a configuration, the plurality of inclined brush teeth 50 can be used to effectively apply the substance C to fine areas such as the hairline of the hair H.

[0042] Furthermore, in this embodiment, the brush base 20 is further configured to include tip comb teeth 60 that protrude from the tip surface toward the tip. By adopting such a configuration, the application of the material C can be performed well to fine areas such as the hairline of the hair H. Furthermore, the relatively viscous material C that adheres to the brush base 20 cannot pass through between the multiple tip comb teeth 60. Therefore, it is possible to effectively prevent the material C that has been applied to the hair H from adhering to the brush base 20 again and accumulating on the back surface of the brush base 20 from the tip side.

[0043] Furthermore, in this embodiment, the brush base 20 is configured to be connected via a connecting portion 12 that slopes downward from the tip of the grip portion 10 toward the tip. By adopting such a configuration, the brush base 20 can be protruded downward (toward the hair H) relative to the grip portion 10, thereby effectively preventing the user's hands holding the grip portion 10 from touching the hair H and causing the application substance C to adhere to the hair H.

[0044] In this embodiment, reinforcing edges 22 extending upward are formed on the left and right ends of the brush base 20. By adopting such a configuration, it is possible to effectively prevent the application material C adhering to the brush base 20 from going over the reinforcing edges 22 and wrapping around to the back surface of the brush base 20 and accumulating thereon.

[0045] In this embodiment, holding portions 25 for holding the application material C are formed on the left-right inner sides of the main brush teeth 30. This configuration makes it easier to squeeze the application material C onto the brush base 20, and allows the application material C held on the brush base 20 to be gradually applied to the hair H, allowing for efficient use.

[0046] Although the present disclosure has been described based on various drawings and examples, it should be noted that those skilled in the art can easily make various modifications and alterations based on the present disclosure. Therefore, it should be noted that these modifications and alterations are included in the scope of the present invention. For example, the functions included in each component can be rearranged so as not to cause logical inconsistencies, and multiple components can be combined into one or divided. It should be understood that these modifications and alterations are also included in the scope of the present invention.

[0047] For example, in this embodiment, the application brush 100 is an integrally molded product, but is not limited to this form. The application brush 100 is not limited to an integrally molded product, and may be configured by assembling multiple components. For example, the brush base 20 and the grip portion 10 may be prepared as separate components and connected by means of fitting or the like. By forming the brush base 20 and the grip portion 10 from different materials, they can be formed from synthetic resin materials suited to their respective functions, thereby enabling them to perform more desirable functions.
