Description

  The present invention relates to a brush with a comb that is particularly suitable for use in applying mascara liquid, and intends to further improve the usability of the brush.

  Mascara is a type of cosmetic that is applied to the eyelashes to enhance the beauty of the eyes. As the applicator, comb-type ones with comb teeth arranged in the longitudinal direction of the support rod and a plurality of hook-like projections are arranged. The brush type is the mainstream, and it was the current situation that the cosmetic manufacturer decides which applicator to use according to the contents.

  By the way, depending on the consumer who actually uses cosmetics, there is a demand for an applicator that has both functions, and the development of a product corresponding to it has been desired.

As a prior art regarding this point, there has been proposed a mascara brush in which a comb-like comb is formed on an application brush having an application part formed by twisting a wire (core wire) (see, for example, Patent Document 1). ). Although this mascara brush has been devised in response to consumer demands, the mascara brush has a structure in which a wire is inserted and fixed to the shaft part on which the comb is formed, so depending on the usage situation and the diameter of the wire, There was a possibility that the shaft and the wire would be unfixed and the wire would come out.

  The subject of this invention exists in the place which proposes the brush with a comb with the ease of use which can be used properly according to a use condition.

The present invention is a brush in which a plurality of hook-shaped protrusions are arranged and a group of the protrusions is disposed on a support rod as an application portion,
A brush with a comb, wherein a comb that is harder than the application portion is integrally formed on the outer surface of the support rod and in a region excluding the application portion.

  In the brush configured as described above, it is preferable that the application portion and the comb are integrated with the support rod by injection molding.

  Further, the application part and the comb are made of an elastomer, and the hardness is obtained by changing any one selected from a molding thickness, an array pitch, and a diameter, or a combination of two or more selected from them. To change.

  Furthermore, the application portion may be made of a soft material, the comb may be made of a hard material, and one of them may be integrated with the support rod by insert molding or two-color molding.

  Since the application part (corresponding to the brush part) in which the hook-shaped projections are arranged and the comb are integrally formed on the outer surface of the support rod, it can be used in accordance with the use situation.

  Since both the application part and the comb are integrally formed on the support rod, the application part and the comb are not easily dropped off, and stable application is possible.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows the overall structure of a mascara container. In the figure, 1 is a container for storing mascara liquid, 2 is a cap that is detachably attached to the mouth of the container 1, and 3 is fixedly held by the cap 2. A rod 4 is a brush with a comb that is fixedly held at the tip of the rod 3, and 5 is a squeezing member that is disposed at the mouth of the container 1 and adjusts the amount of contents attached to the brush 4.

  2 to 4 are views showing only the comb-equipped brush 4 taken out, FIG. 2 is a side view, FIG. 3 is a rear view, and FIG. 4 is a front view.

The comb-equipped brush 4 according to the present invention has a coating rod (corresponding to a brush portion) in which a support rod 4a connected to the rod 3 and a plurality of hook-shaped projections 4b ₁ are arranged in nine rows in the range of 180 ° in the circumferential direction of the rod 3. and 4b, the outer surface of the supporting rod 4a, and comprises a comb-tooth 4c ₁ of a plurality sequences to comb 4c in a region excluding the coating portion 4b.

The comb-equipped brush 4 is made of a soft material such as an elastomer (for example, a polyester-based elastomer), and the application portion 4b and the comb 4c are integrally formed on the support rod 4a. The comb-shaped protrusion 4b ₁ and the comb 4c The comb teeth 4c ₁ do not easily fall off, and can be selectively used according to the application situation by simply rotating (reversing) the support rod 4a.

Normally, the application part 4b is used to uniformly apply the mascara solution to the entire eyelashes, so it is composed of a soft material, and the comb 4c is used to prepare the eyelashes after applying the mascara solution. In the case where an elastomer made of the same material is used for both the coating portion 4b and the comb 4c, either one of the thickness t, the diameter d, the arrangement pitch P, or the like is used. The hardness is changed by selectively selecting and adjusting two or more of them. In the example shown in the drawings, and鍼状protrusions 4b ₁ having a diameter (maximum portion) 0.3 mm of the coating portion 4b, the thickness of the comb teeth 4c ₁ thickness of the comb teeth 4c ₁ of the comb 4c (maximum portion) as 0.4mm The diameter is about 1.3 times the diameter of the hook-shaped protrusion 4b ₁ , thereby making the comb teeth 4c ₁ harder than the hook-shaped protrusion 4b ₁ .

  The application part 4b and the comb 4c can be made of different materials. In this case, insert molding or two-color molding in which one of the members is molded in advance and the other is injection molded after insertion. Thus, integration with the support rod 4a is achieved.

  As described above, when the hardness is adjusted to be suitable for the application, not only the usability is improved, but also the usability is improved.

  As described above, the application part 4b and the comb 4c have been described for the case where a polyester-based elastomer is applied. Polyoxymethylene or the like can also be used. When an elastomer is selected as the material, the surface hardness is preferably 50 to 80 (ASTM D2240). This is because if the hardness is less than 50, the moldability is inferior, whereas if it exceeds 80, the coated part becomes too hard and the feeling of use becomes worse. Also, polypropylene, polybutylene terephthalate, polyoxymethylene, or the like can be applied to the support rod 4a.

  Although the support rod 4a and the rod 3 are illustrated as separate objects, they may be integrated, and this point is not limited.

The comb teeth 4c ₁ of the comb 4c, its thickness in order to exhibit the function to arrange the eyelashes may have to vary from 0.35～0.55Mm,鍼状protrusions 4b ₁ and uniformly mascara to eyelashes coating In order to do this, a circular cross-section is applied, and the diameter can be changed in the range of 0.2 to 0.4 mm. Further, the ratio between the diameter of the hook-shaped protrusion 4b ₁ and the thickness of the comb tooth 4c ₁ is preferably in the range of 1: 1.1-1: 2.0, and more preferably in the range of 1: 1.30-1: 1.50. . It should be noted that the range and the number of rows in which the hook-shaped protrusions 4b ₁ are formed are not limited to those provided in 9 rows in the range of 180 ° in the circumferential direction of the rod 3, and can be appropriately changed.

  An easy-to-use brush that can properly use the comb and the application portion according to the use situation can be provided.

It is the figure which showed the structure of the mascara container provided with the brush according to this invention. It is the figure which showed the side of the brush with a comb according to this invention. It is the figure which showed the back surface of FIG. It is the figure which showed the front-end | tip of FIG.
