Description

Technical Field

[0001] The present invention relates to an applicator having two or more rows of comb teeth in a direction orthogonal to the direction of combing hair, which is used for applying hair cosmetics such as hair care and hair dyeing.

Background Art

[0002] Conventionally, applicators such as combs and brushes have been used for applying hair cosmetics such as hair care and hair dyeing. For example, an applicator having two rows of comb teeth in a direction orthogonal to the direction of combing hair has been proposed (see, for example, Patent Document 1).

[0003] By the way, the applicator disclosed in Patent Document 1 is provided with an application member capable of impregnating a hair cosmetic, and by combing the hair with the comb teeth while applying the hair cosmetic, the hair cosmetic is applied to the hair.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, applicators used for applying conventional hair cosmetics such as hair dyeing, including the applicator disclosed in Patent Document 1, generally have straight comb teeth in which the axial direction of the comb teeth and the die ejection direction of the comb tooth forming die coincide due to molding reasons during the manufacture of the applicator. Therefore, there is a tendency for portions of the hair that do not contact the comb teeth to not be coated with the hair cosmetic, and it is necessary to repeat the hair combing operation in order to uniformly apply the hair cosmetic, resulting in the problem that it takes time to apply the hair cosmetic.

[0006] In view of the problems of the conventional applicators described above, the present invention aims to provide an applicator that makes it less likely for areas of hair cosmetic to be left unapplied, eliminates the need to repeatedly comb the hair to evenly apply the hair cosmetic, and allows for the application of hair cosmetic in a short amount of time. [Means for solving the problem]

[0007] To achieve the above objective, the present invention provides an applicator equipped with two or more rows of comb teeth perpendicular to the direction in which hair is combed, characterized in that at least one row of comb teeth is a deformed comb tooth in which the axial direction of the comb teeth differs from the mold-cutting direction of the comb teeth.

[0008] In this case, at least two rows of the comb teeth can be made of deformed comb teeth where the axial direction of the comb teeth and the molding direction of the comb teeth are different.

[0009] Furthermore, at least one row of the comb teeth can be composed of comb teeth (comb teeth with a normal straight shape) in which the axial direction of the comb teeth coincides with the mold release direction of the mold for forming the comb teeth.

[0010] Furthermore, the comb can be configured such that the axial direction of one row of teeth and the axial direction of the other rows of teeth intersect with a gap between them (in a twisted position).

[0011] Furthermore, the deformed comb teeth can be made up of bent comb teeth.

[0012] Furthermore, the deformed comb teeth can be configured to have a large-diameter portion and / or a small-diameter portion on the shaft of the comb teeth.

[0013] Furthermore, a recess can be formed in the base portion of the applicator, and the impregnating body can be provided in the recess.

[0014] Furthermore, the base portion of the applicator can be constructed by integrating a base portion with one row of comb teeth and a base portion with other rows of comb teeth via a fitting portion. [Effects of the Invention]

[0015] According to the applicator of the present invention, the applicator is provided with two or more rows of comb teeth perpendicular to the direction in which the hair is combed, and at least one row of comb teeth is made of deformed comb teeth in which the axial direction of the comb teeth and the molding direction of the comb teeth are different. By causing twisting and resistance in the hair when combing it with the comb teeth, it is possible to promote contact between the comb teeth, i.e., the hair cosmetic product attached to the comb teeth, and the hair. This makes it less likely that areas of the hair will not be coated with the hair cosmetic, eliminating the need to repeatedly comb the hair to ensure even application, and allowing the hair cosmetic to be applied in a short amount of time.

Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the applicator of the present invention will be described based on the drawings.

Example

[0018] Figs. 1 to 2 show a first embodiment of the applicator of the present invention. This applicator 1A is an applicator provided with four rows of comb teeth (comb tooth rows) 41, 42, 43, 44 in a direction orthogonal to the direction of combing hair, and among the comb teeth (comb tooth rows), two rows of comb teeth (comb tooth rows) 43, 44 are formed of deformed comb teeth in which the axial direction of the comb teeth 43, 44 is different from the die cutting direction of the mold of the comb teeth 43, 44.

[0019] Here, the "axis of the comb tooth" means a virtual line connecting the rising part at the root of the comb tooth and the tip of the comb tooth. In addition, the "deformed comb teeth in which the axial direction of the comb teeth is different from the die cutting direction of the mold of the comb teeth" refers to the axial direction of the deformed comb teeth is configured to intersect (be in a twisted position) with a gap from the axial direction of normal straight comb teeth (comb teeth in which the axial direction of the comb teeth and the die cutting direction of the mold of the comb teeth coincide), comb teeth formed of bent comb teeth, or comb teeth having a large-diameter part and / or a small-diameter part in the axial part of the comb teeth.

[0020] In this embodiment, of the comb teeth (rows of comb teeth), two rows of comb teeth (rows of comb teeth) 41 and 42 are made up of normal straight comb teeth, where the axial direction of the comb teeth 41 and 42 coincides with the mold release direction of the mold for the comb teeth 41 and 42 (up and down direction in Figure 2(b). The parting line PL divides the mold into fixed and movable sides). The remaining two rows of comb teeth (rows of comb teeth) 43 and 44 are made up of deformed comb teeth (combs 43 and 44 are oblique comb teeth in which the axial directions of the comb teeth 43 and 44 differ from each other) where the axial direction of the comb teeth 43 and 44 coincides with the mold release direction of the mold for the comb teeth 43 and 44 (up and down direction in Figure 2(b). The parting line PL divides the mold into fixed and movable sides). This configuration ensures that the comb teeth (rows of teeth) 41 and 42 (which are parallel to each other), the comb teeth (rows of teeth) 43, and the comb teeth (rows of teeth) 44 intersect with a gap between them (in a twisted position).

[0021] The two rows of comb teeth (comb tooth rows) 41 and 42 are integrally molded to a first base portion 31 formed at the tip of the main shaft portion 2 that extends from a gripping portion (not shown) which also serves as the cap of the container, similar to the applicator disclosed in Patent Document 1. The comb teeth (comb tooth rows) 43 are integrally molded to a second base portion 32 which is integrally molded to the first base portion 31 via a hinge portion 51. The comb teeth (comb tooth rows) 44 are integrally molded to a third base portion 33 which is integrally molded to the first base portion 31 via a hinge portion 52.

[0022] The first base portion 31 and the second base portion 32, and the first base portion 31 and the third base portion 33 are integrated after molding via fitting portions 61a, 61b and fitting portions 62a, 62b to form the base portion 3 of the applicator 1A.

[0023] In this embodiment, a recess 31a is formed in the first base portion 31 of the base portion 3, and a hair cosmetic impregnation body (not shown) is placed in this recess 31a. Here, the recess 31a can be configured as having a bottom, or it can be configured to penetrate at least a portion of the recess.

[0024] The applicator 1A is integrally molded using injection molding with a synthetic resin such as polypropylene resin.

[0025] When the applicator 1A is used, for example, to apply hair manicure as a hair cosmetic, the height dimensions of the comb teeth 41, 42, 43, and 44 are set to 1 to 10 mm, preferably 2 to 5 mm (3 mm in this embodiment), but are not limited to this, and can be set to 10 mm or more depending on the application.

[0026] The basic configuration of the applicator 1A in this embodiment is as described above, but its configuration can also be modified as follows. • The tip of the main shaft portion 2 is provided with a gripping portion that does not also serve as the container cap, allowing it to be used as an independent applicator. - A flow path for hair cosmetic is formed in the main shaft portion 2, communicating with a recess 31a where a hair cosmetic impregnation body is disposed, allowing the hair cosmetic to be supplied directly from the container to which the main shaft portion 2 is attached. - The recess 31a of the first base portion 31 on which the impregnated body for hair cosmetics is placed is omitted. Omit one or two of the four rows of comb teeth (comb teeth rows) 41, 42, 43, or 44. In this case, either comb teeth (rows of comb teeth) 43 or 44 is left in place. If comb teeth (rows of comb teeth) 41 and 42 are omitted, the first base portion 31 is also omitted, and the second base portion 32 and the third base portion 33 can be integrally molded via a hinge portion and directly integrated via a fitting portion. The tip of the applicator 1A is provided with comb teeth (rows of comb teeth) (not shown) in a direction parallel to the direction of combing the hair. These comb teeth (rows of comb teeth) can be formed on the first base portion 31 (as well as the second base portion 32 and the third base portion 33), or integrally molded on a fourth base portion (not shown) which is integrally molded on the first base portion 31 via a hinge portion. The base portion of the applicator is formed by individually molding the first base portion 31 (comb teeth (rows of comb teeth) 41, 42), the second base portion 32 (comb teeth (rows of comb teeth) 43), and the third base portion 33 (comb teeth (rows of comb teeth) 44), and then integrating them via a fitting portion after molding.

[0027] According to this applicator 1A, four rows of comb teeth (comb tooth rows) 41, 42, 43, and 44 are provided in a direction perpendicular to the direction in which the hair is combed. Two of the rows of comb teeth 41, 42, 43, and 44 are made of deformed comb teeth, where the axial direction of the comb teeth 43, and 44 differs from the mold-cutting direction of the comb teeth 43, and 44. By causing the hair to twist when combed with the comb teeth 41, 42, 43, and 44, contact between the hair cosmetic product attached to the comb teeth 41, 42, 43, and 44 and the hair can be promoted. This makes it less likely that areas of the hair will not be coated with the hair cosmetic, eliminating the need to repeatedly comb the hair to ensure even application, and allowing the hair cosmetic to be applied in a short amount of time. [Examples]

[0028] Figure 3 shows a second embodiment of the applicator of the present invention. This applicator 1B is modified by replacing the comb teeth (rows of comb teeth) 43 and 44 of the applicator 1A of the first embodiment with bent comb teeth. This allows for increased contact between the hair and the hair, by actively creating a twist in the hair when combing it with the comb teeth 41, 42, 43, and 44, i.e., the hair cosmetic product attached to the comb teeth 41, 42, 43, and 44.

[0029] The other configurations and functions of the applicator 1B in this embodiment are the same as those of the applicator 1A in the first embodiment described above. [Examples]

[0030] Figure 4 shows a third embodiment of the applicator of the present invention. This applicator 1C is modified in which, instead of the comb teeth (rows of comb teeth) 43 and 44 of the applicator 1A of the first embodiment described above, comb teeth (rows of comb teeth) 43 and 44 have large diameter portions 43a and 44a (in this embodiment, two stages of large diameter portions 43a and 44a) on their shafts. Here, it is preferable to make the height dimension of the comb teeth (rows of comb teeth) 43 and 44 larger than the height dimension of the comb teeth (rows of comb teeth) 41 and 42. This actively creates resistance in the hair when combing it with the comb teeth 41, 42, 43, and 44, and increases the amount of hair cosmetic held by the large diameter portions 43a and 44a of the comb teeth (rows of teeth) 43 and 44. This further promotes contact between the hair cosmetic attached to the comb teeth 41, 42, 43, and 44, i.e., the hair, and the hair. Furthermore, since the hair cosmetic is held in place by the large diameter portions 43a and 44a of the comb teeth (rows of teeth) 43 and 44, and is less likely to transfer to the tip of the shaft, it is possible to prevent the hair cosmetic from adhering to the scalp.

[0031] The other configurations and functions of the applicator 1C in this embodiment are the same as those of the applicator 1A in the first embodiment described above. [Examples]

[0032] Figure 5 shows a fourth embodiment of the applicator of the present invention. This applicator 1D is modified in which, instead of the comb teeth (rows of comb teeth) 43 and 44 of the applicator 1A of the first embodiment described above, comb teeth (rows of comb teeth) 43 and 44 have small diameter portions 43b and 44b (in this embodiment, two stages of small diameter portions 43b and 44b) on their shafts. This actively creates resistance in the hair when combing it with the comb teeth 41, 42, 43, and 44, and increases the amount of hair cosmetic held by the small diameter portions 43b and 44b of the comb teeth (rows of teeth) 43 and 44. This further promotes contact between the hair cosmetic attached to the comb teeth 41, 42, 43, and 44, i.e., the hair, and the hair. Furthermore, since the hair cosmetic is held in the small diameter portions 43b and 44b of the comb teeth (rows of teeth) 43 and 44, and is less likely to transfer to the tip of the shaft, it is possible to prevent the hair cosmetic from adhering to the scalp.

[0033] The other configurations and operations of the applicator 1D in this embodiment are the same as those of the applicator 1A in the first embodiment described above. [Examples]

[0034] Figure 6 shows a fifth embodiment of the applicator of the present invention. This applicator 1E is modified by using comb teeth (rows of comb teeth) 43 and 44 of the applicator 1A of the first embodiment, with the comb teeth having large diameter portions 43a and 44a (in this embodiment, two stages of large diameter portions 43a and 44a) on their shafts. As a result, similar to the applicator 1A of the first embodiment, when combing hair with the comb teeth 41, 42, 43, and 44, twisting is created in the hair, and resistance is actively created in the hair when combing with the comb teeth 41, 42, 43, and 44. In addition, the amount of hair cosmetic held by the large diameter portions 43a and 44a of the comb teeth (rows of comb teeth) 43 and 44 can be increased, thereby further promoting contact between the hair cosmetic attached to the comb teeth 41, 42, 43, and 44, i.e., the hair, and the hair. Furthermore, since the hair cosmetic is held in place by the large diameter portions 43a and 44a of the comb teeth (rows of teeth) 43 and 44, and is less likely to transfer to the tip of the shaft, it is possible to prevent the hair cosmetic from adhering to the scalp.

[0035] The other configurations and functions of the applicator 1E in this embodiment are the same as those of the applicator 1A in the first embodiment described above. [Examples]

[0036] Figure 7 shows a sixth embodiment of the applicator of the present invention. This applicator 1F is modified by using comb teeth (rows of comb teeth) 43 and 44 of the applicator 1A of the first embodiment, with the comb teeth having small diameter portions 43b and 44b (in this embodiment, two stages of small diameter portions 43b and 44b) on their shafts. As a result, similar to the applicator 1A of the first embodiment, when combing hair with the comb teeth 41, 42, 43, and 44, twisting is created in the hair, and resistance is actively created in the hair when combing with the comb teeth 41, 42, 43, and 44. In addition, the amount of hair cosmetic held by the small diameter portions 43b and 44b of the comb teeth (rows of comb teeth) 43 and 44 can be increased, thereby further promoting contact between the hair cosmetic attached to the comb teeth 41, 42, 43, and 44, i.e., the hair, and the hair. Furthermore, the hair cosmetic is held in the small diameter portions 43b and 44b of the comb teeth (rows of teeth) 43 and 44. This makes it less likely for the product to transfer to the tip of the shaft, thus preventing hair care products from adhering to the scalp.

[0037] The other configurations and functions of the applicator 1F in this embodiment are the same as those of the applicator 1A in the first embodiment described above.

[0038] Although the applicator of the present invention has been described above based on several embodiments, the present invention is not limited to the configurations described in the above embodiments, and its configuration can be modified as appropriate without departing from the spirit of the invention, such as by appropriately combining the configurations described in each embodiment. [Industrial applicability]

[0039] The applicator of the present invention is suitable for use as an applicator for applying hair cosmetics such as hair manicures and gray hair dyes, as it is less likely to leave areas where hair cosmetics are not applied, eliminates the need to repeatedly comb the hair to evenly apply the hair cosmetics, and allows for quick application of hair cosmetics.
