Description

Applicator and applicator provided with the applicator

The present invention relates to an applied body and an applicator provided with this applied body.

More specifically, a coated material used for applying, writing, etc., which does not wear out easily when applying, writing, etc., is stable, and allows for accurate and easy processing of the applied portion, and this coated material. It relates to the applicator provided.

Conventionally, various applicators have been widely used in fields such as writing, drawing, and application.

Regarding these various applicators, examination of materials, shapes, etc. is always conducted to find each of them of good quality.

For example, in Japanese Patent Application Laid-Open No. 2012-239739 (Patent Document 1), a material for a long, flat coating material that is consistent in quality, flexible, and does not cause the fibers to become disorganized even after long-term use is proposed. It is becoming.

This coating material is a fiber bundle made by pulling nylon fibers neatly in the longitudinal direction into a desired shape, for example, a cross-sectional shape such as a horizontally elongated oval, a rectangle with rounded corners, a rectangle, a modified triangle, or a shape from the side. When viewed, it is made into a flat, long body with the desired cross-sectional shape by heating and compressing it with a stepped die in the shape of a pipe with an empty hole in the shape of a water drop.

Additionally, in Japanese Utility Model Registration No. 3196621 (Patent Document 2), a core material for a cosmetic pen suitable for applying more delicate makeup is proposed.

The core material of this cosmetic pen is made of fibrous material, is formed to extend along a predetermined axis direction, and has a tip portion located at one end of the axis direction to become a pen tip, and the tip portion is perpendicular to the axis direction. It is formed so that the thickness in a predetermined direction gradually decreases toward the tip, and at least one cutting portion cut along the axis direction is provided on the tip surface of the tip portion.

Since the material for a coated material disclosed in Patent Document 1 is long and flat with a short side width of 0.5 to 2.0 mm, there was a risk of bending when writing or drawing was performed with strong force.

In addition, since the coating material made of the coating material is flat and has a small volume, when it is used as an applicator, the amount of liquid absorbed from the liquid storage portion inside the applicator and released into the application portion is limited, causing wear. Because it is easy, further improvements are required.

In addition, when using it as an eyebrow, since the eyebrow is often applied on top of a makeup base such as foundation, the foundation etc. on the skin adheres to the tip of the applied material, causing clogging, making it more likely to wear off. Even better improvements are required.

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 is circular.

Therefore, because this core material is prone to rolling, there is a problem that it is difficult to accurately perform the desired processing in a stable state during processing.

It is ~5.0 times the thickness, and is configured so that the thickness of at least one end in the width direction is 1.8 mm or less.

Therefore, according to the above-mentioned coating body, the coating main body constituting this coating body has a large volume and a large holding amount of liquid substances (ink, liquid cosmetics, etc.) compared to a conventional flat elongated body with a thickness of 0.5 to 2.0 mm. Therefore, even when application, etc. is performed quickly, the outflow amount of the liquid substance increases, occurrence of wear is suppressed, and application, etc. can be performed stably.

In addition, the above-mentioned coated body also has the characteristic (absorption-release characteristic) of being able to easily release or absorb liquid substances by applying and releasing the application pressure during application, etc.

In the above-described coated body, the coated body can be formed by heat-compressing a fiber material, particularly a fiber bundle made of a desired fiber material, and bonding and fixing it by impregnation with a synthetic resin.

With this configuration, in the application main body, the fibers therein are arranged in the axial direction, so that a conduction path for the liquid substance is formed along the axial direction.

Therefore, when the applied body composed of the above-mentioned application main body is combined with, for example, a storage section filled with a liquid material and placed in a predetermined container to form an applicator, the retention performance of the liquid material flowing out of the storage section and the above-mentioned The absorption and release characteristics of liquid substances in the storage unit can be improved.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of the coated body which concerns on this invention will be specifically described based on the accompanying drawings.

In addition, the coated body of the present invention is not limited to the illustrated embodiment, and improvements can be made without changing the gist of the invention.

As shown in FIG. 1, the coated body 1 (hereinafter referred to as “coated body 1”) according to the present invention is composed of a long plate-shaped coating body 2 with a predetermined thickness.

The applicator 2 has a maximum width It is configured to be 1.2 to 5.0 times the thickness (Y), preferably 1.2 to 3.0 times, and more preferably 1.2 to 2.0 times.

With this configuration, the applicator 2 can perform desired processing such as punching processing or cutting processing in a stable state.

Additionally, this effect is significant when processing such as punching processing or cutting processing is performed by lying down the applied body 1 composed of the application main body 2, as shown in FIG. 6 .

In this case, if the ratio of the maximum width ( Tends to lose.

Additionally, when processing and setting the coated body, it becomes difficult to distinguish between the thickness direction and the width direction, which tends to reduce workability.

In addition, the application main body 2 is configured so that the thickness of at least one end in the width direction (left and right directions in FIG. 1) is 1.8 mm or less, preferably about 0.2 to 1.8 mm.

With this configuration, when performing processing, especially punching processing, resistance during punching can be reduced and consumption of the punching machine can be prevented, thereby improving productivity.

Additionally, if application is performed using the end portion having the above-described thickness, a thin line can be drawn.

In Figure 1, the coating main body constituting the coated body is configured so that only the thickness of one end (right end) in the width direction is within the above range, so a thin line can be drawn at one end and a thick line can be drawn at the other end. I can draw. Therefore, it becomes possible to use a single coated material separately for thin and thick lines depending on the purpose.

Moreover, in the applied body 1, the volume of the applied body 2 is larger than that of a conventional flat elongated body with a thickness of 0.5 to 2.0 mm, so the amount of liquid matter (ink, liquid cosmetics, etc.) held is also large. Therefore, even when application, etc. is performed quickly, the outflow amount of the liquid substance increases, occurrence of wear is suppressed, and application, etc. can be performed stably.

In addition, as shown in FIG. 2, in the above-mentioned applicator 2, especially the applicator 2 made of a porous material, when it is pressurized and compressed by application pressure during application, etc., its volume is reduced, causing internal While releasing the liquid substance, when the pressure is released, the volume is restored and the liquid (liquid substance) is released. For example, by combining the applied body composed of the above-mentioned application subject with a storage portion filled with the liquid substance, When placed in a predetermined container and used as an applicator, the property of internal absorption can also be obtained from the storage portion.

This effect is significant because, when the application subject is viewed in a cross section perpendicular to its longitudinal direction, the hardness of the outer peripheral portion in the radial direction is higher than the hardness of the central portion, because the central portion becomes prone to crushing.

Additionally, the absorption and release characteristics of the liquid can be adjusted to a desired level by adjusting the hardness of the applicator or changing the shape of the longitudinal end of the applicator.

For example, in FIG. 3, one end of the applicator 2 in the short side direction (the end on the side where the thickness of the applicator 2 is maximum) is pressed and compressed in the thickness direction and applied in the longitudinal direction. By performing cutting processing to form a cutting surface inclined at a predetermined angle ( θ ), a cutting portion 3 of the required depth is formed.

The periphery of the cut portion 3 is a portion where the soft surface of the center of the applicator 2 is exposed, and can be deformed by pressure, thereby improving the absorption and release characteristics of the liquid.

In addition, regarding the size of the cutting portion, the long side between the two opposing sides, which will be described later, is changed to change the size of the arc when forming it to bulge outward in an arc shape, or to change the size of the arc to bulge outward in an arc shape. It can be adjusted by changing the size of the shape or the angle ( θ ).

For example, when the circular arc is not formed or when the angle θ is increased, a small cutting portion is formed.

Accordingly, the amount of absorption and release of the liquid can be adjusted by the presence or absence of the arc being formed, a change in the size of the arc, or a change in the angle θ .

There is no particular limitation on the shape of the cross-section (transverse cross-section shape) perpendicular to the longitudinal direction of the applicator 2, as long as the width and thickness of the cross-section are within the specific range, and a solid cross-sectional shape. You just need to have it.

Examples of the cross-sectional shape include polygonal shapes such as triangles, squares (trapezoids, diamonds, etc.), and hexagons, or combinations of two or more of these shapes symmetrically up and down and/or left and right.

In addition, the cross-sectional shape may have at least one of its angles rounded, may be symmetrical in the vertical or horizontal direction, or may be asymmetrical.

In addition, the cross-sectional shape is preferably such that at least one of its sides is formed as a straight line from the viewpoint of enabling accurate positioning with respect to the object of application, etc., as long as the application subject does not roll or can be positioned stably. For example, as shown in FIG. 7(B), at least one of the sides may bulge outward in an arc shape or may be concave in an arc shape toward the inside.

With this configuration, it becomes possible to accurately align the coating with the target, and it becomes possible to stably perform the desired processing in a stationary state.

Specifically, the cross-sectional shape may be shaped as shown in Figures 4 (A) to (E), depending on the intended use.

In addition, the cross-sectional shape shown in FIG. 4 is configured to have a pair of hypotenuses by gradually increasing the thickness (height) from one of the left and right edges toward the other.

That is, the application main body having the cross-sectional shape shown in FIG. 4 has a pair of upward inclined surfaces that gradually slope upward in the thickness direction from the outside to the inside.

With this configuration, the coating body 2 having the above-mentioned cross-sectional shape has different thicknesses at one end and the other end in the short side direction, so that in the coating body 1 composed of the above-mentioned application body 2, the It is possible to distinguish between the use of different line widths at one end and the other end of the short side direction.

More preferably, the cross-sectional shape is a substantially triangular shape or a substantially square shape where both surfaces in the thickness direction of the application main body form two opposing sides 2b and 2c, and more preferably, the applicator 2 ) is approximately triangular in shape, with both surfaces in the thickness direction forming two opposing sides, or is approximately trapezoidal in shape, in which both surfaces in the thickness direction of the application main body form a pair of angle sides.

With this configuration, when performing desired processing on the longitudinal end of the applicator 2, it becomes possible to perform the processing stably.

In addition, the cross-sectional shape is preferably configured so that the angle R formed by the two sides 2b and 2c formed by both surfaces in the thickness direction of the applicator 2 is 10 to 40 degrees.

With this configuration, when performing desired processing, especially punching processing, on the longitudinal end of the applicator 2, it becomes possible to perform the processing more stably.

The cross-sectional shape is particularly preferably a substantially trapezoidal shape in which both sides in the thickness direction of the applicator 2 constitute each side formed by a pair of hypotenuses, the length of the upper side is 0.2 to 1.8 mm, and the lower side is The length is 1.8 to 4.0 mm, the height is 1.2 to 5.0 times (preferably 1.2 to 3.0 times, more preferably 1.2 to 2.0 times) the lower side, and the opening angle formed by each pair of sides is 10 to 40°. It is composed of a trapezoidal shape (especially an isometric trapezoidal shape).

If the length of the upper side is less than 0.2 mm, the tip becomes sharp, so it tends to cause pain to the skin when used as an applicator, and if it exceeds 1.8 mm, when used as an applicator, the thickness is thick at one end and the other end in the direction of the short side. Since they are the same, there is a tendency that line width usage cannot be distinguished.

In addition, if the length of the upper side is less than 0.2 mm, the coating main body becomes thin, its strength is extremely reduced, and it becomes easy to crush, so it is difficult to adjust the position of the coating main body during processing or to apply the coating consisting of the coating main body. When assembling a sieve or applicator into a container during manufacture, it tends to be difficult to perform these stably.

If the length of the lower side is less than 1.8 mm, it becomes thin and tends to bend when a strong force is applied, and if it exceeds 4.0 mm, it tends to be difficult to stably perform fine processing or punching processing.

If the height is less than 1.2 times the length of the lower side, it becomes difficult to distinguish the length and width of the cross-sectional shape, and alignment during processing tends to become difficult. If the height is more than 5.0 times the lower side, it tends to become difficult to distinguish between the vertical and horizontal sides of the cross-sectional shape. If it becomes too large, it becomes difficult to do fine makeup work, and it becomes necessary to use a large processing machine, which tends to lead to an increase in cost.

If the opening angle is less than 10°, when used as a coated material, the thickness becomes the same at one end and the other end of the short side, so there is a tendency for line widths to be used differently, and if it exceeds 40°, when used as a coated material, If the inclination angle is too large, it tends to become difficult to use.

Preferably, the cross-sectional shape is configured such that both sides in the thickness direction of the applicator have a substantially triangular shape forming two sides, or a substantially square shape where both surfaces in the thickness direction of the applicator have formed two opposing sides. is formed so that the long side interposed between the two opposing sides bulges outward in an arc shape.

In Fig. 1, the cross-sectional shape orthogonal to the longitudinal direction of the applicator 2 is, as shown in Fig. 1 (B), a substantially isometric trapezoid shape, and among the edges on the left and right sides, the edge on the long side, that is, the opposing The lower side 2d sandwiched between the hypotenuses 2b and 2c is configured to bulge outward in an arc shape.

In the case of this configuration, when the application main body is pressed and compressed during the desired processing, especially punching processing, the long side, that is, the part outside the portion having the maximum thickness in the short side direction of the applicator main body, is, in particular, the above-mentioned When the hardness of the applicator is low, for example, in the range of 5 to 80 as measured by a type A durometer based on JIS K6301, it is stably crushed toward the outside in the short side direction, so the process of the applicator is It becomes possible to perform this stably and precisely, and it becomes possible to accurately and precisely process the longitudinal end of the application body into a desired shape.

For example, when punching is performed as shown in FIG. 6 so that the longitudinal end of the applicator 2 is formed into a comb shape so that the applicator 2 shown in FIG. 5 is formed, at the end The processing shape becomes more precise.

On the other hand, in the case where the long side 2d interposed between the two opposing sides is not formed to bulge outward in an arc shape, that is, is formed in a straight shape, one of the two sides and the long side The angles (edges) between (2b and 2d, 2c and 2d) are all acute angles, and the structural strength of the application main body increases, so when this applicator is pressed and compressed in the thickness direction, the corners are deformed. difficult.

Therefore, since the corner portion is difficult to deform, deformation occurs from the central portion in the thickness direction of the long side 2d, and therefore, in the comb shape formed by punching processing, the shape may be disturbed near the long side 2d. Therefore, it becomes difficult to form (process) stably.

As the material constituting the application body 2, a material capable of absorbing and retaining liquid is selected.

The above materials include, for example, porous materials such as foams with open cells that absorb and retain liquid through capillary forces, or raised materials or hair transplant materials, especially porous materials obtained by bundling fibers and bonding them with a synthetic resin. A type of sieve includes a fiber bundle with appropriate strength.

Among these materials, select fiber materials such as fiber bundles that can absorb and hold liquid, are porous, and have fibers inside them arranged in the axial direction, thereby forming a conduction path for the liquid along the axial direction. It is desirable to do so.

In addition, as the fiber or fiber material constituting the fiber bundle, thermoplastic resin fibers such as polyester fibers, acrylic fibers, and nylon fibers are preferably selected, and more preferably, they have a high water absorption rate and absorb liquid. Nylon fibers are selected from the viewpoint of swelling, lowering hardness, providing good feel, and being easy to deform under pressure such as application pressure.

When the applicator is made of thermoplastic resin fibers, the applicator has better absorption, retention, and release (outflow) of liquid.

Additionally, in this embodiment, the applicator 2 is made of nylon fiber.

The porosity of the coating agent, especially the coating agent made of a fiber material, is preferably in the range of 30% to 88%, more preferably in the range of 35% to 88%, and even more preferably in the range of 50% to 80%. .

If the porosity is less than 30%, the flow path for the liquid becomes smaller, which tends to make it difficult for sufficient liquid to flow out. If it exceeds 88%, the structure required to maintain the shape of the application subject decreases, and durability during use decreases. It tends to get worse.

The hardness of the coating agent, especially the coating agent made of a fiber material, is preferably in the range of 5 to 80, more preferably in the range of 10 to 70.

If the hardness is less than 5, durability tends to deteriorate, such as loosening (cracks) when the number of uses exceeds a predetermined value, and if it exceeds 80, the coating agent becomes hard and the feeling of use tends to be poor. there is.

Additionally, by setting the hardness within the above range, the absorption and release characteristics of the liquid become more likely to be expressed.

In addition, in the present invention, the hardness is durometer hardness, and is measured by pushing a pressure needle into a cross section cut perpendicular to the longitudinal direction of the coated body using a type A durometer hardness tester compliant with JIS K6301.

In addition, regarding the above-mentioned hardness, when viewed in a transverse section perpendicular to the longitudinal direction of the application subject, the hardness at the outer peripheral portion in the radial direction may be higher than the hardness at the central portion.

This configuration can be realized, for example, when the applicator is made of a fiber bundle material, by distributing the fibers and/or the synthetic resin that adheres and fixes them to the outer periphery of the applicator.

Figure 9 is an electron microscope photograph of a cross section of the applied subject.

In FIG. 9, it can be seen that since a larger amount of fibers and synthetic resin that adhesively fixes them exist in the outer peripheral portion of the applicator than in the center of the applicator, the hardness in the radial outer peripheral portion is higher than the hardness in the central portion. You can.

In the case of this configuration, when the coating material composed of the application main body is pressurized and compressed by pressing it against an object such as application, the radial center of the end portion (applied portion) of the coating material is deformed because its hardness is low. While the volume decreases, when the applied body is separated from the application object and the pressurization is released, the volume tries to recover to its original size.

Therefore, for example, in the case of eyebrow use, even if a blockage occurs at the applicator (longitudinal end) of the applicator due to adhesion of a makeup base (foundation, etc.), the pressurization and its release are performed. By repeating, in the case where the applied body composed of the above-mentioned application main body is combined with a storage section filled with the liquid material and placed in a predetermined container to form an applicator, in addition to the liquid material being absorbed from the storage section, the application section Since cracks and gaps are formed due to the deformation, the liquid material flows out from these cracks and gaps, making it possible to continue applying, etc.

In addition, the application subject itself is prevented from bending, and the effect of providing excellent shape retention performance and a feeling of writing or use in the applied body can be obtained.

The applicator 2 can be formed into an arbitrary length depending on the intended use by contacting the object during application, etc.

Of the two ends in the longitudinal direction of the applicator 2, at least one end is subjected to known methods such as punching, cutting, cutting, polishing, etc., so that application in a desired form can be performed depending on the application. You can do any processing you want.

For example, when punching is performed on the longitudinal end of the applicator 2, this end may be shaped like a wave, a sawtooth shape (comb shape), a step shape, a heart shape, or a bow shape (cannonball shape). It can be shaped like this.

When cutting at least one end of both ends of the applicator 2 in the longitudinal direction, as shown in FIGS. 7 and 8, the longitudinal direction (front-back direction in FIGS. 7 and 8) is symmetrical. Cutting processing can be performed.

In this case, the applied body 1 composed of the application main body 2 can be used as an applicator at both ends in the longitudinal direction, and can be placed in a predetermined container without considering the front-back direction and used as an applicator (writing instrument). (including, etc.) can be assembled, making it easy to manufacture the applicator.

In addition, in FIG. 8, round portions are formed at acute angle tips (right ends) 2e, 2e of both ends in the longitudinal direction of the applicator 2.

Additionally, at the longitudinal end of the applicator 2, at least one of its corners may be chamfered or rounded along the short side 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, bundles (fiber bundles) of the desired fiber material arranged neatly in the longitudinal direction are formed into a desired cross-sectional shape. Heat molding is performed on a die showing the shape to obtain a fiber convergence body, and the obtained fiber convergence body is adhered and fixed by impregnation with synthetic resin, and the ends of the obtained long plate-shaped body are processed into the desired shape as needed. , the applicator can be obtained.

The coated body 1 of this structure can be used as an applicator for writing, drawing, applying, applying makeup, etc., or as a coated body for a writing instrument.

Therefore, the coated body 1 can be used as an applicator by, for example, combining it with a storage portion filled with ink, etc., as needed, and placing it in a predetermined container.

Regarding the applicator provided with the coated body 1 of this structure, for example, a batting containing liquid cosmetics or ink is attached to one end side of the coated body 1. It can be assembled by inserting and fixing it in the container so that the application portion on the other end side protrudes to the required length.

Example

Below, the present invention will be described in detail using examples, but the present invention is not limited to these examples.

[Example]

(1) Manufacturing of application agent

Nylon fibers with a fiber thickness of 1 decitex were concentrated so that the total amount was 10,000 decitex to obtain a nylon fiber bundle.

The obtained nylon fiber bundle had a cross-sectional shape of an isometric trapezoid with an upper side of 0.9 mm, a lower side of 2.5 mm, a height of 3.6 mm, and an opening angle of 34° on each side, and each of the upper and lower sides was bulged outward in an arc shape. It was passed through a die having a substantially isometric trapezoid shape, heat molded, and then immersed in a synthetic resin solution with the composition shown in Table 1 below to obtain a nylon fiber bundle having a substantially isometric trapezoid shape.

Thereafter, the obtained approximately isometric trapezoid-shaped nylon fiber bundle was placed in a hot air drying furnace set at a temperature of 130 to 140°C to remove the solvent and harden the synthetic resin to obtain a long plate-shaped coating main body.

Composition of synthetic resin solution (unit: mass%) ingredient Mixing ratio Urethane (isocyanate + polyol) 5 solvent 95

The obtained application main body has a cross-sectional shape perpendicular to the longitudinal direction of an isometric trapezoid with an upper side of 0.9 mm, a lower side of 2.5 mm, a height of 3.6 mm, and an opening angle of 34 degrees on each side, and each of the upper and lower sides is an arc facing outward. It was approximately an isometric trapezoid bulged in shape, its porosity was 71%, and the hardness of its center was 17 as measured with a JIS K6301 Type A durometer hardness tester.

(2) Manufacture of coated body

One end of the obtained application main body in the longitudinal direction is cut so that the maximum length in the longitudinal direction is 32 mm and an inclined surface at an angle of 45° is formed with respect to the longitudinal direction, and the other end is given a comb shape shown in Figure 5. By performing punching processing to form this, a coated body was obtained.

＜Results＞

In the coated body obtained in the above example, the other longitudinal end of the coated body constituting the coated body was accurately and precisely processed into a three-dimensional comb shape with four teeth.

From the above, in the coated body of the present invention, the coating main body constituting it is configured so that the longer side of the left and right edges in the cross section perpendicular to the longitudinal direction bulges outward in an arc shape, so that the coating main body constituting the coating main body It is clear that it is possible to accurately and precisely process the longitudinal end into a desired shape.

The coated body of the present invention is composed of a long plate-shaped coating main body, and the maximum width of the coating main body in a cross section perpendicular to its longitudinal direction is 1.2 of the maximum thickness of the coating main body in the cross section. It is configured to be ~5.0 times the thickness, and the thickness of at least one end in the width direction is 1.8 mm or less.

Therefore, compared to the flat elongated body with a thickness of 0.5 to 2.0 mm used as a conventional coating material, this coating material has a large amount of liquid material such as ink, so even when application is performed quickly, the outflow amount of the liquid material increases. In addition, the occurrence of abrasion is suppressed, making it possible to perform stable application, etc., and making it possible to easily release or absorb liquid substances by pressurizing and releasing it, so it is used for writing, drawing, application, makeup, etc. As a coating material for an applicator, it can be used for a wider range of purposes.
