[Problems to be solved by the invention]
However, since the eyelids of the user have different sizes and shapes, applying a uniform bow-shaped mascara brush along the eyelashes as in the former, depending on the user, may cause mascara to be applied. In some cases, the mascara brush easily adheres to the skin on the eyebrows side because the tip of the mascara brush always faces the eyebrows on the eyebrows side during application. In addition, since the size and shape of the user's eyelids are different from each other, unpainting often occurs in a single application, and after all, the number of arc-shaped mascara brushes is changed by changing the angle and position. Although it is applied repeatedly, there is a problem that it is difficult to apply a three-dimensional eyelash part that differs for each user with a mascara brush having a constant curvature like the bow shape.
[0007]
Further, in the latter case, in which the core body having the brush hairs is bent with respect to at least two axes that are not parallel to each other, the core body is bent several times so that the direction of the core body changes, and the core body is bent by the bending. Depending on the angle and position of some brush hairs applied to the eyelashes, other brush hairs may hit the skin because they are not configured to be located on the same plane and are bent in various directions. It is said that when used (turned), the outer shape changes and it is effective for application. However, since it is bent in various directions as described above, brush hairs that do not touch the skin before rotation hit the skin by rotation and cause mascara. May adhere, making it difficult to apply. Further, Patent Literature 2 describes that the eyelid may be bent so as to match the bending of the eyelid, but this causes the same problem as the former. Further, as described above, since the core is bent several times so as to change the direction and the core is not positioned on the same plane due to the bending, the production is troublesome and the mass productivity is low.
[0008]
The present invention has been made in order to solve such problems, and a cosmetic brush which makes it easy to apply mascara and other cosmetics and makes it difficult for the cosmetics to adhere to the skin during application, and It is another object of the present invention to provide a method of manufacturing a cosmetic brush suitable for mass-production by easily manufacturing the cosmetic brush.

It is formed by pinching the brush bristles and twisting tightly, grasping both ends of this shaft-shaped core body, twisting at least one end coaxially in the direction in which the core wire is further tightened, and a non-shaft-shaped spiral cosmetic There is a method of obtaining a brush.
[0016]
In addition, as a method of easily manufacturing a cosmetic brush having a spiral shape in which the end of the core is turned at a predetermined radius of rotation, there are two ends of a shaft-shaped core having brush hairs attached thereto. , And turning at least one end at a predetermined radius of rotation to obtain a non-axial helical cosmetic brush.
[0017]
Further, as a method of manufacturing a cosmetic brush having a spiral shape in which the end of the core body is turned at a predetermined radius of rotation, a shaft-shaped core body having brush bristles is used. A brush hair is sandwiched between the core wires of the book, tightly twisted and formed, and both ends of the shaft-shaped core body are gripped, and at least one end is rotated in a direction in which the core wire is further tightened with a predetermined radius of rotation, and a non-shaft body is formed. To obtain a spiral spiral cosmetic brush.
[0018]
In addition, when forming the shaft-shaped core body having the brush bristles into a non-shaft-shaped spiral, by moving at least one end to the other end side, the spiral is more easily manufactured. .
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of a cosmetic brush and a method of manufacturing the same according to the present invention will be described with reference to FIGS. FIG. 1 is a plan view showing a mascara brush according to a first embodiment of the present invention, FIG. 2 is a front view of the mascara brush shown in FIG. 1, and FIG. 3 is a front perspective view of the mascara brush shown in FIG. FIGS. 4 and 5 are views showing a mascara brush according to the second embodiment of the present invention, and FIGS. 6 and 7 are schematic views showing a method of manufacturing the mascara brush.
[0020]
As shown in FIGS. 1 to 3, in the mascara brush 1, a torsion core body 2 formed by twisting two core wires is provided with brush bristles 3. The portion of the body 2 to which the brush bristles 3 are attached is formed in a spiral shape that continuously bends and spreads in a radial direction and an extension direction in a non-axial manner.
[0021]
The non-axial spiral shape is manufactured as follows. First, the brush bristles 3 are sandwiched between two straight SUS core wires, for example, and tightly twisted, so that the radially protruding brush bristles 3 are helically arranged along the axial direction. 6), and as shown in FIG. 6, both ends of a portion A of the shaft-shaped torsion core to which the brush bristles 3 are attached are gripped by a dedicated machine, and one end is coaxial. Twist in the direction to tighten the core wire further. Then, the core wire extends in the radial direction and the extension direction so as to form a non-axial spiral, and the mascara brush 1 shown in FIGS. 1 to 3 can be easily obtained. In this case, both ends of the shaft-shaped torsion core may be coaxially twisted in opposite directions to further tighten the core.
[0022]
The pitch and radius of the non-axial spiral of the mascara brush 1 thus manufactured are smaller than the pitch and radius of the axial spiral of the torsion core itself formed by tightly tightening. Each is enlarged.
[0023]
In addition, this non-shaft spiral shape is such that both ends of a portion A where the brush bristles 3 of the shaft torsion core are mounted are gripped by a special machine, and one end is fixed to a predetermined end as shown in FIG. It can also be easily obtained by turning the core wire in the direction in which the core wire is further tightened with the turning radius r. At this time, both ends of the shaft-shaped torsion core may be turned in a direction in which the core is further tightened with a predetermined rotation radius.
[0024]
In the manufacturing method shown in FIGS. 6 and 7, when the shaft-shaped torsion core body having the brush bristles 3 is formed into a non-shaft-shaped spiral (when twisting in FIG. It is preferable to move at least one end to the other end as shown by the arrow in the drawing (when turning at 7), because the non-axial helix is more easily formed.
[0025]
Incidentally, in each of the above-described manufacturing methods, when at least one end of the shaft-shaped torsion core body sandwiching the brush bristles 3 is coaxially twisted or turned at a predetermined radius of rotation in the direction in which the core wire is loosened, the brush bristles are It is impossible for 3 to drop off from the two core wires and serve as a product.
[0026]
According to the mascara brush 1 obtained in this manner, the spiral mascara brush is formed into a spiral that continuously bends and spreads in a radial direction and an extension direction in a non-axial manner, that is, a spiral spiral that has a three-dimensional curve that spreads three-dimensionally. I have. As a result, the following operations and effects are obtained.
[0027]
That is, compared to a two-dimensional constant warp such as a conventional bow shape, the number of selected locations where the brush bristles 3 can be appropriately applied to the three-dimensional eyelash portions different for each user increases, It is easy to apply mascara.
[0028]
In addition, as shown in FIG. 2, when the tip is used in a state where the left side in the drawing is the inter-brows side, the mascara is less likely to adhere to the inter-brows skin by using it in a state separated from the inter-brows side. ing.
[0029]
Also, compared to a conventional core body that is bent about at least two axes that are not parallel to each other, if some brush bristles 3 are applied to eyelashes, other brush bristles 3 may hit the skin depending on the angle or position. Is reduced, and the mascara is less likely to adhere to the skin.
[0030]
Furthermore, when the mascara brush 1 is rotated and used, the range covered by the brush bristles 3 is accommodated in the spiral range without deviating from the spiral range continuous in the core body extending direction at a constant radius, and the mascara is removed from the skin. In addition, the application range in which the brush bristles 3 and the eyelashes are in contact with the brush bristles 3 and the eyelashes are naturally moved in parallel in the extending direction of the core and expanded, so that the application of mascara is further facilitated.
[0031]
FIG. 4 is a plan view showing a mascara brush according to the second embodiment of the present invention, and FIG. 5 is a front perspective view of the mascara brush shown in FIG.
[0032]
The mascara brush 11 according to the second embodiment is manufactured by the same manufacturing method as that of the first embodiment, and has a brush body 13 attached thereto and is continuously bent to form a non-axial spiral. 12, the spiral pitch (not the spiral pitch of the shaft-shaped torsion core itself, but the spiral pitch that spreads non-axially) is shorter than the spiral pitch of the mascara brush 1 of the first embodiment. .
[0033]
It is needless to say that the same effects as in the first embodiment can be obtained even with such a configuration, and which of the mascara brushes 1 and 11 of the embodiment is used depends on the user. Selected.
[0034]
As described above, the present invention has been specifically described based on the embodiment. However, the present invention is not limited to the above embodiment. Is a torsion core formed by tightly twisting the brush bristles 3 and 13 between two core wires, but may be a single non-twisted brush bristle holder or the like other than the torsion core, As described above, at least one end of the one untwisted brush bristle holder is coaxially twisted or turned with a predetermined radius of rotation to obtain a non-shaft spiral mascara brush. You may do it.
[0035]
Further, in the above-described embodiment, the mascara brushes 1 and 11 are used as the makeup brushes because the application to eyelashes growing along the spherical eyelids is particularly effective. It is also applicable to brushes for personal use.
[0036]
【The invention's effect】
According to such a cosmetic brush, the cosmetic brush is formed into a spiral shape in which the core body provided with the brush bristles continuously bends and extends in the radial and extension directions in an off-axis shape, that is, a three-dimensional curve that expands three-dimensionally. It has a spiral configuration. For this reason, (1) a selection that can appropriately apply brush bristle to a part of a three-dimensional application portion different for each user as compared with a two-dimensional constant warp such as a conventional bow shape. The number of locations is increased, and application of the cosmetic is facilitated. (2) Use can be made with the tip of the non-axial helical brush positioned on the side away from the skin side, and makeup can be applied at the time of application. And (3) the angle and position of the brush hairs on the application part is lower than that of a conventional core body that is bent about at least two axes that are not parallel to each other. In some cases, the brush bristles are prevented from hitting the skin, making it more difficult for the cosmetic to adhere to the skin during application. (4) When the spiral brush is rotated and used, the range of the brush bristles is a constant radius. Is within the spiral range continuous in the core body extension direction It is contained within the helical range without coming off, making it more difficult for the cosmetic to adhere to the skin at the time of application, and expanding the application range in which the brush hair and the application portion come into contact with each other in the core extending direction by itself. Further, the application of the cosmetic is further facilitated.
[0037]
Further, the method for manufacturing a cosmetic brush according to the present invention is characterized in that both ends of a shaft-shaped core body having brush hairs attached thereto are gripped and at least one end is coaxially twisted, or at least one end is rotated by a predetermined amount.
