2. Description of the Related Art Conventionally, various applicators have been widely used in fields such as writing, drawing, and coating.
For these various applicators, studies are constantly being made on their materials, shapes, etc. in order to obtain high-quality ones.

For example, Japanese Unexamined Patent Application Publication No. 2012-239739 (Patent Document 1) proposes a long and flat material for an applicator that has uniform quality and is flexible, and whose fibers do not come apart even after long-term use. ing.

This material for the applicator body is formed by forming a fiber bundle in which nylon fibers are aligned in the longitudinal direction, and forming pores having a desired shape, for example, a laterally elongated ellipse, a rounded rectangle, a rectangle, a deformed triangle, or a water drop shape when viewed from the side. It consists of a flat elongated body having a desired cross-sectional shape by heating and compressing with a pipe-shaped deformed die.

Furthermore, Japanese Utility Model Registration No. 3196621 (Patent Document 2) proposes a core material for a cosmetic pen that is suitable for applying finer makeup.

The core material of this cosmetic pen is made of fibrous material and is formed so as to extend along a predetermined axial direction.
Having a tip portion that is located on one end side in the axial direction and serves as a pen tip,
The tip portion is formed such that the thickness in a predetermined direction orthogonal to the axial direction gradually decreases toward the tip,
At least one notch cut along the axial direction is provided in the tip surface of the tip portion.

Japanese Patent Application Laid-Open No. 2012-239739 (Claims, Fig. 1) Utility model registration No. 3196621 (scope of utility model registration, Figures 2 and 3)

The coating body material disclosed in Patent Document 1 is long and flat with a short side width of 0.5 to 2.0 mm. It was likely to bend.
Furthermore, since the applicator made of the material for the applicator is flat and has a small volume, when it is used as an applicator, the liquid is absorbed from the liquid reservoir inside the applicator and transferred to the applicator. There is a need for further improvement in that the amount released is limited and that it is easy to rub.
Furthermore, when used as an eyebrow, eyebrow is often applied over a makeup base such as a foundation, so the foundation on the skin adheres to the tip of the application body, causing clogging and making it easier to rub. Further improvement is demanded also in the following points.

The core material of the cosmetic pen disclosed in Patent Document 2 is configured so that the cross-sectional shape orthogonal to the axial direction thereof is circular.
Therefore, since this core material tends to roll, there is a problem that it is difficult to perform desired processing accurately in a stable state during processing.

Therefore, according to the applicator, the applicator body constituting the applicator has a larger volume than a conventional flat elongated body with a thickness of 0.5 to 2.0 mm, and a liquid substance (ink, etc.) (liquid cosmetics, etc.) is also increased, so even if the application is performed quickly, the outflow of the liquid is increased and the occurrence of rubbing is suppressed, so that the application can be performed stably. becomes possible.
Furthermore, the applicator has a characteristic (absorption/discharge characteristic) of being able to easily release or absorb a liquid substance by applying pressure such as a coating pressure during application or the like and releasing the pressure.

In the present invention, the maximum width of the coating body in a cross section orthogonal to the longitudinal direction is 1.2 to 5.0 times the maximum thickness of the coating body in the cross section. The thickness of one end of the direction is 0.2 to 1.8 mm and the thickness of the other end is 1.8 to 4.0 mm, preferably perpendicular to the longitudinal direction.

In the applicator body, the applicator body may be formed by heating and compressing a fiber bundle made of a fiber material, particularly a desired fiber material, and bonding and fixing the fiber bundle by impregnating it with a synthetic resin.
With such a configuration, the fibers inside the application body are arranged in the axial direction, so that the conducting path for the liquid is formed along the axial direction.
Therefore, when the applicator composed mainly of the applicator is combined with, for example, a storage section filled with a liquid material and housed in a predetermined container to form an applicator, the liquid material flowing out from the storage section It is possible to improve the retention performance of the liquid and the absorption and release characteristics of the liquid in the reservoir.

The applicator may be configured such that the cross-sectional shape of the applicator exhibits a polygonal shape, or a shape obtained by combining two or more of these shapes vertically and/or horizontally symmetrically.

The cross-sectional shape of the application body is a substantially triangular shape in which both sides in the thickness direction of the application body constitute two sides, or a substantially square shape in which both sides in the thickness direction of the application body constitute two opposite sides. Further, the angle formed by the two sides formed by both sides in the thickness direction of the main body to be applied can be 10 to 40°.
With such a configuration, when the desired processing is applied to the longitudinal end portion of the application body, the processing can be stably performed.

Hereinafter, embodiments of the applicator body according to the present invention will be specifically described with reference to the accompanying drawings.
It should be noted that the applicator of the present invention is not limited to the illustrated embodiments, and improvements can be made without changing the gist of the invention.

As shown in FIG. 1, an applicator 1 (hereinafter referred to as "applicator 1") according to the present invention comprises a long plate-like applicator 2 having a required thickness.

The coating body 2 has a maximum width X of 1.2 to 5.0 times the maximum thickness Y of the coating body 2 in the cross section perpendicular to its longitudinal direction (the front-rear direction in FIG. 1). 0 times, preferably 1.2 to 3.0 times, more preferably 1.2 to 2.0 times.
With such a configuration, the application main body 2 can perform the desired processing such as punching or cutting in a stable state.
Note that this effect is remarkable when processing such as punching and cutting is carried out with the coating body 1 composed of the coating body 2 laid down as shown in FIG.
In this case, if the ratio of the maximum width X to the maximum thickness Y is less than 1.2 times, the cross-sectional shape approaches a circular shape, which causes the application body to roll, etc., so that processing is performed in a stable state. tends to be difficult.
Furthermore, during processing, it becomes difficult to distinguish between the thickness direction and the width direction when setting the application body, and workability tends to decrease.

Further, the coating body 2 is configured so that the thickness of at least one end in the width direction (horizontal direction in FIG. 1) is 1.8 mm or less, preferably about 0.2 to 1.8 mm. .
With such a configuration, when performing processing, particularly punching, the resistance during punching can be reduced, and wear and tear of the punching machine can be prevented, thereby improving productivity.
Furthermore, thin lines can be drawn by applying or the like using the edge portion having the thickness described above.
In FIG. 1, the coating main body constituting the coating body is configured so that only one end (right end) in the width direction thereof has a thickness within the above range, so that a fine line can be drawn at one end. A thick line can also be drawn at the other end. Therefore, it is possible to use one applicator for thin lines and thick lines depending on the application.

Moreover, in the applicator 1, the volume of the applicator body 2 is larger than that of a conventional flat elongated body having a thickness of 0.5 to 2.0 mm, so that liquid substances (ink, liquid cosmetics, etc.) ), even if the application is performed quickly, the outflow amount of the liquid material increases and the occurrence of rubbing is suppressed, so that the application can be performed stably. Become.
Furthermore, as shown in FIG. 2, the coating main body 2, particularly the coating main body 2 made of a porous material, is pressurized and compressed by a coating pressure during coating, etc., and its volume is reduced. When the pressurization is released, the volume of the liquid recovers and the liquid is released, for example, the application body composed mainly of the above application is released. When combined with a filled reservoir and housed in a predetermined container to form an applicator, it is also possible to obtain the characteristic of absorbing inside from the reservoir.
This effect is obtained when the application body is configured such that the hardness of the radially outer peripheral portion is higher than the hardness of the central portion in a cross-sectional view perpendicular to the longitudinal direction, the central portion is likely to be crushed. , is pronounced.

As for the absorption/release characteristics of the liquid, the absorption/release characteristics of a desired magnitude can be obtained by adjusting the hardness of the coating body, changing the shape of the longitudinal end of the coating body, or the like. .

For example, in FIG. 3, at one end of the application body 2 in the width direction (the end on the side where the thickness of the application body 2 is maximized), while being pressurized and compressed in the thickness direction, A notch 3 having a required depth is formed by performing a cutting process so as to form a cut surface inclined at a predetermined angle θ.
The periphery of the notch 3 is a portion where the soft surface of the central portion of the application body 2 is exposed, and is deformable by pressurization, thereby improving liquid absorption and release characteristics.

Regarding the size of the notch, the size of the arc when forming a long side intervening between two opposing sides to be described later so as to swell outward in an arc shape may be changed. It can be adjusted by changing the size of the arc-shaped bulging shape, the angle θ, or the like.
For example, if the arc is not formed or if the angle θ is increased, a small notch is formed.
Therefore, the amount of absorption and release of the liquid can be adjusted by whether or not the arc is formed, by changing the size of the arc, and by changing the angle θ.

The cross-sectional shape (cross-sectional shape) perpendicular to the longitudinal direction of the application body 2 is not particularly limited as long as the width and thickness of the cross-section are within the above specific ranges, and has a solid cross-sectional shape. It is good if there is
Examples of the cross-sectional shape include polygonal shapes such as triangles, quadrilaterals (trapezoids, rhombuses, etc.), hexagons, and the like, or those obtained by combining two or more of these vertically and/or horizontally symmetrically.
The cross-sectional shape may have at least one rounded corner, may be symmetrical in the vertical or horizontal direction, or may be asymmetrical.

Furthermore, the cross-sectional shape is preferably formed such that at least one of its sides is a straight line from the viewpoint of enabling accurate alignment with an object to be coated. At least one of its sides bulges outward in an arc or dents inward in an arc, as shown in FIG. It can be anything.
With such a configuration, it is possible to perform accurate positioning with respect to an object to be coated or the like, and it is possible to perform desired processing stably in a stationary (or lying) state.

Specifically, the cross-sectional shape can also be shaped as shown in FIGS. 4(A) to 4(E) depending on the application.

Each of the cross-sectional shapes shown in FIG. 4 is configured to have a pair of oblique sides by gradually increasing the thickness (height) from one of the left and right side edges toward the other.
That is, the application main body having the cross-sectional shape shown in FIG. 4 has a pair of ascending inclined surfaces that gradually incline upward from the outside toward the inside in the thickness direction.
With such a configuration, in the applicator body 2 having the cross-sectional shape, one end and the other end in the transverse direction have different thicknesses. Different line widths can be used properly on one end side and the other end side in the transverse direction.

More preferably, the cross-sectional shape is a substantially triangular or substantially quadrangular shape forming two sides 2b and 2c facing each other in the thickness direction of the coating body. It has a substantially triangular shape in which both sides in the direction constitute two opposite sides, or a substantially trapezoidal shape in which both sides in the thickness direction of the application body constitute a pair of legs.
With such a configuration, when a desired processing is applied to the longitudinal end portion of the application main body 2, the processing can be performed stably.

The cross-sectional shape is preferably configured such that the angle R formed by the two sides 2b and 2c formed by both sides of the application body 2 in the thickness direction is 10 to 40°.
With such a configuration, when the longitudinal end portion of the applicator body 2 is to be subjected to desired processing, particularly punching, the processing can be performed more stably.

The cross-sectional shape is particularly preferably a substantially trapezoidal shape in which both sides in the thickness direction of the application body 2 constitute legs formed by a pair of oblique sides, and the length of the upper base is 0.2 to 1.0 mm. 8 mm, the length of the base is 1.8 to 4.0 mm, and the height is 1.2 to 5.0 times (preferably 1.2 to 3.0 times, more preferably 1.2 to 5.0 times) the base. 2 to 2.0 times) and a trapezoidal shape (especially an isosceles trapezoidal shape) with a pair of leg sides forming an opening angle of 10 to 40°.

If the length of the upper base is less than 0.2 mm, the pointed tip tends to hurt the skin when used as an applicator. Since the thickness is the same at one end and the other end in the width direction, it tends to be impossible to use different line widths.
Furthermore, when the length of the upper base is less than 0.2 mm, the coating body becomes thin, its strength is extremely reduced, and it is easily crushed. It tends to be difficult to stably assemble the applicator body composed of , to the container when manufacturing the applicator.

If the length of the lower base is less than 1.8 mm, it becomes thin and tends to bend when a strong force is applied. It tends to be difficult to apply.

If the height is less than 1.2 times the length of the bottom, there is a tendency that it becomes difficult to distinguish between vertical and horizontal cross-sectional shapes, and alignment during processing tends to be difficult. If it exceeds 0.0 times, the applied body becomes too large, making it difficult to carry out fine decorative work, requiring the use of a large-sized processing machine, which tends to lead to an increase in cost.

If the opening angle is less than 10°, the thickness of the application body will be the same at one end and the other end in the width direction, so there is a tendency that the line width cannot be properly used, and it exceeds 40°. As a result, the inclination angle is too high when used as an applicator, which tends to make it difficult to use.

The cross-sectional shape is configured to be a substantially triangular shape in which both sides in the thickness direction of the application main body constitute two sides, or a substantially square shape in which both surfaces in the thickness direction of the application main body constitute two opposite sides. In this case, preferably, the long side interposed between the two opposing sides is formed to bulge outward in an arc shape.

In FIG. 1, the cross-sectional shape perpendicular to the longitudinal direction of the application main body 2 is a substantially isosceles trapezoidal shape, as shown in FIG. That is, the lower base 2d interposed between the opposing oblique sides 2b and 2c is configured to bulge outward in an arc shape.

In the case of such a configuration, when the application body is pressurized and compressed during desired processing, particularly punching, the long side, that is, the portion having the maximum thickness in the short side direction of the application body, The outer portion is stably crushed toward the outside in the transverse direction, especially when the hardness of the main body of the coating is low, for example, when the hardness is in the range of 5 to 80 as measured by the A-type durometer according to JIS K6301. Therefore, it is possible to stably and precisely process the application main body, and it is possible to accurately and precisely process the longitudinal end portion of the application main body into a desired shape.
For example, as shown in FIG. 6, in order to form the coating body 2 shown in FIG. The processed shape in becomes more precise.

On the other hand, when the long side (2d) intervening between the two opposing sides is not formed to bulge outward in an arc shape, that is, when it is formed in a straight line, The angles (corners) sandwiched by one side and the long side (2b and 2d, 2c and 2d) are all acute angles, and the structural strength of the coating body increases. When pressurized and compressed, the corners are difficult to deform.
Therefore, since the corners are difficult to deform, deformation occurs from the central portion in the thickness direction of the long side (2d). Therefore, in the comb shape formed by punching, the shape may be disturbed in the vicinity of the long side 2d. Therefore, it becomes difficult to form (process) stably.

A material that can absorb and retain liquid is selected as the material that constitutes the application body 2 .
The material may be, for example, a porous body such as a foam having open cells that absorbs and retains liquid by capillary force, or a raised body or a flocked body, particularly obtained by bundling fibers and bonding them with a synthetic resin. It is a type of porous material, and includes fiber bundles having moderate strength.
Among these materials, fiber bundles and the like are capable of absorbing and retaining liquid, are porous, and the fibers inside are arranged in the axial direction, so that the liquid conduction path is formed along the axial direction. It is preferable to select a fibrous material formed by
As the fibers and fiber materials constituting the fiber bundle, thermoplastic resin fibers such as polyester fibers, acrylic fibers, and nylon fibers are preferably selected. Nylon fiber is selected from the viewpoint that it swells when it absorbs, loses hardness, feels good on the skin, and is easily deformed by pressure such as application pressure.

When the application main body is composed of thermoplastic resin fibers, the application main body has even better ability to absorb, hold and release (outflow) liquid.
In this embodiment, the application body 2 is made of nylon fiber.

The porosity of the coating body, particularly the coating body made of a fibrous material, is preferably in the range of 30% to 88%, more preferably in the range of 35% to 88%, still more preferably in the range of 50% to 80%. be.
If the porosity is less than 30%, the flow path of the liquid tends to be reduced, so it tends to be difficult for the liquid to flow out sufficiently. The body tends to be less and the durability during use tends to be worse.

The hardness of the coating body, particularly the coating body made of a fibrous material, is preferably in the range of 5-80, more preferably in the range of 10-70.
When the hardness is less than 5, the durability tends to be deteriorated, such as the occurrence of breakage when the number of times of use exceeds a predetermined value. tend to become
Furthermore, by setting the hardness within the above range, the absorption and release properties of the liquid are more likely to be exhibited.

In the present invention, the hardness is durometer hardness, which is measured by inserting an indenter into a cross section cut perpendicular to the longitudinal direction of the coating main body using an A-type durometer hardness tester conforming to JISK6301. is.

Further, regarding the hardness, in a cross-sectional view perpendicular to the longitudinal direction of the coating main body, the hardness in the radial outer peripheral portion can be configured to be higher than the hardness in the central portion.
This configuration can be realized, for example, by unevenly distributing the fibers and/or the synthetic resin for bonding and fixing the fibers and/or the fibers to the outer peripheral portion of the application main body when the application main body is composed of a fiber bundle material.

FIG. 9 is an electron micrograph of a cross section of the main coating.
In FIG. 9, since a larger amount of fibers and a synthetic resin for bonding and fixing the fibers are present in the outer peripheral portion of the application main body than in the central portion of the application main body, the hardness at the radial outer peripheral portion is the same as that at the center. It can be seen that the hardness is higher than that in the part.

In the case of such a configuration, when the applicator composed mainly of the applicator is pressurized and compressed by, for example, pressing it against an object to be applied or the like, the radial center of the end portion (applying portion) of the applicator will be Since its hardness is low, it deforms and its volume decreases, while when the application body is separated from the application object and the pressure is released, the volume tends to recover to its original size.
Therefore, for example, in the case of eyebrow application, even if clogging occurs due to adhesion of makeup base (foundation etc.) in the application part (longitudinal direction end) of the main application, the pressurization By repeating and releasing, the applicator composed mainly of the applicator is combined with a reservoir filled with the liquid material and stored in a predetermined container to form an applicator. In addition to being absorbed, cracks and gaps are formed in the application portion due to the deformation, so the liquid flows out from these cracks and gaps, and it is possible to continue application etc. .

In addition, it is possible to prevent bending of the application body itself, and to obtain the effect of being able to obtain excellent shape retention performance and writing feeling or feeling of use in the application body.

The application main body 2 comes into contact with an object during application, etc., and can be formed to have any length depending on the application.

At least one of the longitudinal ends of the application main body 2 is subjected to punching, cutting, cutting, polishing, etc. so that application can be performed in a desired form according to the application. Desired processing can be performed by well-known methods.

For example, in the case of punching the end portion in the longitudinal direction of the coating main body 2, the end portion may be formed in a wave shape, a sawtooth shape (comb shape), a step shape, a heart shape, an arc shape (cannonball shape), or the like. can be shaped.

When performing the cutting process on at least one end of the longitudinal direction ends of the application main body 2, as shown in FIGS. A cutting process can be applied.
In this case, the applicator body 1 composed of the applicator main body 2 can be used as the applicator portion at both ends in the longitudinal direction. Since the applicator (including writing implements and the like) can be assembled by accommodating them, manufacturing of the applicator is facilitated.
In addition, in FIG. 8, the sharp points (right ends) 2e, 2e at both ends in the longitudinal direction of the application main body 2 are rounded.

At the longitudinal end of the application body 2, at least one of the corners may be chamfered or rounded along the lateral direction or the thickness direction.

Regarding the method of forming the application main body, for example, when a fiber material is selected as the material of the application main body, a desired fiber material bundle (fiber bundle) aligned in the longitudinal direction is A fiber bundle is obtained by heat molding with a die having a desired shape, and the obtained fiber bundle is adhered and fixed by impregnating a synthetic resin, and the end portion of the obtained long plate-like body is attached. By processing it into a desired shape as necessary, the subject to be applied can be obtained.

The applicator 1 having such a configuration can be used as an applicator for writing, drawing, coating, makeup, or as an applicator for a writing instrument.
Therefore, the applicator 1 can be used as an applicator in combination with a reservoir filled with ink or the like, if necessary, and housed in a predetermined container.

As for the applicator having the applicator body 1 having such a configuration, for example, one end side of the applicator body 1 is attached with a filling containing a liquid cosmetic or ink, and the applicator part on the other end side of the applicator body 1 is attached. It can be assembled by inserting and fixing it into the container so that it protrudes to the desired length.

The obtained nylon fiber bundle is an isosceles trapezoid with an upper base of 0.9 mm, a lower base of 2.5 mm, a height of 3.6 mm, and a leg opening angle of 34°. Each of them is passed through a die having a substantially isosceles trapezoidal shape that is swollen outward in an arc shape, heat-molded, and then immersed in a synthetic resin solution having the composition shown in Table 1 below. A pedestal-shaped nylon fiber bundle was obtained.
After that, the obtained approximately isosceles trapezoidal nylon fiber bundle is placed in a hot air drying oven set at a temperature of 130 to 140° C. to remove the solvent and harden the synthetic resin to form a long plate. was obtained.

The resulting application body has a cross-sectional shape perpendicular to the longitudinal direction of an isosceles trapezoid with an upper base of 0.9 mm, a lower base of 2.5 mm, a height of 3.6 mm, and an opening angle of 34°. Each of the bottom and the lower bottom has a substantially isosceles trapezoidal shape that bulges outward in an arc shape, and has a porosity of 71%, and the hardness of the central part is measured with a JISK6301A type durometer hardness tester. It was 17.

(2) Manufacture of application body Cut processing is performed so that the maximum length in the longitudinal direction is 32 mm with respect to one end in the longitudinal direction of the obtained application body, and an inclined surface at an angle of 45° with respect to the longitudinal direction is formed. , and the other end was punched to form a comb shape shown in FIG.

<Results>
In the applicator body obtained in the above example, the other longitudinal end of the applicator body constituting the applicator body was accurately and precisely processed into a three-dimensional comb shape having four teeth.
As described above, in the applicator body of the present invention, the applicator main body constituting the applicator body is configured such that the long sides of the left and right side edges in a cross section orthogonal to the longitudinal direction bulge outward in an arc shape. Therefore, it is clear that the longitudinal ends of the application body can be accurately and precisely machined into a desired shape.

The application body of the present invention comprises a long plate-like application body, and the maximum width of the application body in a cross section perpendicular to the longitudinal direction of the application body is the maximum thickness of the application body in the cross section. and 1.2 to 5.0 times the thickness of at least one end in the width direction of 1.8 mm or less.
Therefore, this applicator can hold a large amount of a liquid such as ink as compared with a flat elongated body having a thickness of 0.5 to 2.0 mm, which is conventionally used as an applicator. Even when the pressure is applied, the outflow amount of the liquid is increased, the occurrence of rubbing is suppressed, and it is possible to perform stable application, etc., and the liquid is easily released by pressurizing and releasing it. Since it can also be absorbed, it can be used in a wider range of applications as an applicator body for an applicator for writing, drawing, coating, makeup, and the like.
