[Problems to be solved by the invention]
However, since the size and shape of the user's eyelashes are different from each other, depending on the user, the mascara may not be suitable for applying a uniform bow-shaped mascara brush like the former along the eyelashes. In some cases, it adheres to the skin near the eyes, and since the tip of the mascara brush always faces the eyebrow side when applying, the mascara tends to adhere to the eyebrow side skin. In addition, since the size and shape of the user's eyelids are different from each other in this way, there are many cases in which unpainted portions are left after a single application, and as a result, the number of arcuate mascara brushes is changed by changing the angle and position. However, there is a problem that it is difficult to apply to the three-dimensional eyelash portions which are different for each user with the mascara brush having a certain curvature like the bow shape.
[0007]
Further, in the latter case where the core body provided with the bristles 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 is changed, and the core body is bent by the bending. Since it is not configured in the same plane and is bent in various directions, depending on the angle and position, some brush hair may hit the skin depending on the angle and position, and it may rotate. It is said that when used (turned), the outer shape changes and it is effective for application, but since it is bent in various directions as described above, the brush hair that does not hit the skin before rotation hits the skin by rotation and becomes mascara. May adhere and is difficult to apply. Further, Patent Document 2 describes that the sheet may be bent so as to match the bend of the heel, but this causes the same problem as the former. Furthermore, as described above, the latter is bent several times so that the direction of the core is changed, and is bent so that the core is not positioned on the same plane by the bending, so that the production is troublesome and the mass productivity is low.
[0008]
The present invention has been made to solve such a problem, it is difficult mascara brush mascara adheres to the skin when applied with masker la coating is facilitated, and, the mascara brush easily It aims at providing the manufacturing method of the mascara brush suitable for manufacture and mass production.
[0009]
[Means for Solving the Problems]
The mascara brush according to the present invention is a mascara brush in which the core body is provided with brush hairs for applying mascara , and the core body is formed in a spiral shape that bends continuously in a non-axial shape in the radial direction and in the extending direction. The spiral shape is characterized in that the end portion of the core body is a spiral shape formed by turning with a predetermined radius of rotation .
[0010]
According to such a mascara brush, the core body having the bristles for applying mascara is a spiral that continuously bends in a non-axial shape in the radial direction and in the extension direction, that is, a three-dimensional curved spiral that expands three-dimensionally. It is made into a shape. For this reason, (1) selection that can apply brush bristles appropriately to a portion of a three-dimensional application part that is different for each user as compared to a two-dimensional constant warp like a conventional arcuate shape (2) It can be used in a state where the tip of the non-shaft-shaped spiral brush is positioned on the side away from the skin side, and (3) the conventional cores are not parallel to each other Compared to the one that is bent with respect to at least two axes, when a part of the bristle is applied to the application part, it is reduced that the other bristle hits the skin depending on the angle and position. (4) Spiral brush When rotating, the range covered by the bristle is kept within the spiral range without deviating from the spiral range continuous in the core extending direction at a constant radius, and the brush bristles and the application part are in contact with each other. The range is naturally in the core extension direction It is enlarged and is line movement. Here, this spiral shape is a spiral shape in which the end portion of the core body is rotated with a predetermined rotation radius.
[0016]
Further, as a method of easily manufacturing a mascara brush having a spiral shape in which the end of the core body is rotated at a predetermined rotation radius, a shaft body-shaped core formed by mounting brush hairs for applying mascara is used. A method of obtaining a non-axial spiral mascara brush by gripping both ends of the body and turning at least one end with a predetermined radius of rotation is mentioned.
[0017]
Further, as a method for more easily manufacturing a mascara brush having a spiral shape in which the end portion of the core body is rotated at a predetermined turning radius, two shaft body-shaped core bodies having brush hairs are used. It is formed by sandwiching the bristle between the core wires and twisting them tightly, grasping both ends of this shaft-shaped core body, turning at least one end in a direction that further tightens the core wire with a predetermined rotation radius, and a method of obtaining a spiral mascara brush.
[0018]
In addition, when the shaft-shaped core body having the brush hairs is formed into a non-shaft-shaped spiral, the spiral is more easily manufactured by moving at least one end to the other end. .
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of a cosmetic brush and a method for producing the same according to the present invention will be described with reference to FIGS. 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. 4 and 5 are diagrams showing a mascara brush according to the second embodiment of the present invention, and FIGS. 6 and 7 are schematic diagrams showing a method of manufacturing the mascara brush.
[0020]
As shown in FIGS. 1 to 3, in the mascara brush 1, a twisted core body 2 formed by twisting two core wires includes brush hairs 3, and particularly in the mascara brush 1 of the present embodiment, this core. The portion of the body 2 where the bristles 3 are mounted is formed in a spiral shape that is continuously bent and spreads in a non-axial shape in the radial direction and in the extending direction.
[0021]
This non-axial helical shape is manufactured as follows. First, the brush hairs 3 are sandwiched between two linear SUS core wires or the like, and the brush hairs 3 projecting radially are arranged in a spiral shape along the axial direction (straight line). 6), and then, as shown in FIG. 6, grip both ends of the portion A where the bristle 3 of the shaft-like torsion core is mounted with a dedicated machine, and one end is coaxial. Twist in the direction that the core wire tightens further. Then, the core wire expands to expand in the radial direction and the extending direction so as to form a non-axial spiral, and the mascara brush 1 shown in FIGS. 1 to 3 can be easily obtained. At this time, both ends of the shaft-shaped torsional core may be twisted in the opposite directions where the core wire is further tightened on the same axis.
[0022]
The pitch and radius of the spiral forming the non-shaft shape of the mascara brush 1 manufactured in this way are compared with the pitch and radius of the spiral spiral of the torsion core itself formed by tightly tightening. Each has been enlarged.
[0023]
In addition, this non-shaft-like spiral shape is obtained by gripping both ends of the portion A where the brush hairs 3 of the shaft-like twisted core body are mounted with a dedicated machine, and one end is predetermined as shown in FIG. It can also be easily obtained by rotating the core wire in a direction in which the core wire is further tightened with the rotation radius r. At this time, both ends of the shaft-shaped torsion core may be rotated in a direction in which the core wire 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 having the brush bristles 3 is formed into a non-shaft-shaped spiral (when twisting in FIG. When turning at 7), it is preferable to move at least one end to the other end side as indicated by an arrow in the figure because the non-axial spiral is more easily formed.
[0025]
Incidentally, in each of the above manufacturing methods, when at least one end of a shaft-shaped twisted core body sandwiching the bristles 3 is twisted on the same axis in the direction in which the core wire is loosened or rotated with a predetermined turning radius, It is impossible for 3 to fall off the two core wires and serve as a product.
[0026]
According to the mascara brush 1 obtained in this way, a spiral mascara brush that bends continuously in a non-axial shape in the radial direction and in the extending direction, that is, a three-dimensional curved spiral mascara brush. Yes. As a result, the following actions and effects are achieved.
[0027]
That is, as compared with a two-dimensional constant warp like a conventional arcuate shape, the number of selection points where the brush bristles 3 can be appropriately applied to the three-dimensional eyelash portions that are different for each user increases. Application of mascara is easy.
[0028]
In addition, as shown in FIG. 2, when the tip is positioned on the side away from the eyebrow side when the left side in the drawing is the eyebrow side, the mascara is less likely to adhere to the eyebrow side skin. ing.
[0029]
In addition, when a part of the bristle 3 is applied to the eyelashes, the other bristle 3 hits the skin depending on the angle and position, as compared with a conventional core body that is bent with respect to at least two axes that are not parallel to each other. This reduces the risk that mascara will not adhere to the skin.
[0030]
Furthermore, when the mascara brush 1 is rotated and used, the range covered by the bristles 3 is accommodated in the spiral range without deviating from the spiral range that is continuous in the core extending direction at a constant radius, and the mascara is skinned. Further, the application range where the brush bristles 3 and the eyelashes are in contact with each other is naturally expanded in parallel with the extending direction of the core, thereby making it easier to apply the mascara.
[0031]
4 is a plan view showing a mascara brush according to a 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 the brush body 13 is attached and continuously bent to form a non-axial spiral body. 12 is shorter than the helical pitch of the mascara brush 1 of the first embodiment (the helical pitch spreading in a non-axial shape rather than the helical pitch of the shaft-shaped torsion core itself). .
[0033]
It goes without saying that the same effects as in the first embodiment can be obtained even if configured in this way, and whether the mascara brushes 1 and 11 of which embodiment are used depends on the user. Selected.
[0034]
Although the present invention has been specifically described above based on the embodiment, the present invention is not limited to the above embodiment. For example, in the above embodiment, the cores 2 and 12 are manufactured from the viewpoint of ease of manufacture. Is a twisted core body in which the brush hairs 3 and 13 are sandwiched and tightened tightly between two core wires, but may be a single brush hair holding body other than the twisted core body, for example, As described above, the non-twisted brush bristle holding body is twisted on the same axis or rotated at a predetermined turning radius to obtain a non-axial helical mascara brush. Anyway.
[0036]
【The invention's effect】
According to such a mascara brush, the mascara brush has a three-dimensional shape in which the core body having the bristles for applying the mascara is continuously bent and spirally spreads in a non-axial shape in the radial direction and in the extending direction, that is, three-dimensionally spreads. It is configured to form a curved spiral. For this reason, (1) selection that can apply brush bristles appropriately to a portion of a three-dimensional application part that is different for each user as compared to a two-dimensional constant warp like a conventional arcuate shape The number of locations is increased and the application of the mascara is facilitated. (2) The mascara can be used in a state where the tip of the non-axial helical brush is positioned on the side away from the skin side. It is difficult to adhere to the skin. (3) Depending on the angle and position, when a part of the brush hair is applied to the application part as compared with the conventional core body which is bent with respect to at least two axes which are not parallel to each other, It is reduced that other brush hair hits the skin, and the mascara is more difficult to adhere to the skin at the time of application. (4) When the spiral brush is rotated and used, the range covered by the brush hair is a constant radius and the core. Continuous spiral in the extending direction Housed in no within the helical range deviate from the inner, mascara at the time of application is with is difficult to further adhere to the skin, the application range of contact of the brush bristles and the coating unit with naturally translate the core extending direction enlargement Thus, the mascara can be more easily applied. Here, the spiral shape is a spiral shape in which the end portion of the core body is rotated with a predetermined rotation radius.
[0037]
A method of manufacturing a mascara brush according to the present invention, by turning the two ends of the shaft-like core member made by mounting the bristles for mascara coating grips, whereas the end even without least at a predetermined turning radius, Since the non-shaft-like spiral mascara brush is obtained, the production thereof can be facilitated and is suitable for mass production.
