Hereinafter, embodiments of the coated body according to the present invention will be specifically described with reference to the accompanying drawings.
The coated body of the present invention is not limited to the illustrated examples, and improvements can be made without changing the gist of the invention.

As shown in FIGS. 1 to 4, the coating body 1 (hereinafter referred to as “coating body 1”) according to the present invention is composed of a long rod-shaped coating body 2 and is formed on the outer peripheral surface thereof in the circumferential direction. A groove 3 having a required depth extending is formed.

The material constituting the coating main body 2 is not particularly limited, and a general material can be selected as the material constituting the coating body or the pen tip.
As the material, for example, a fiber material can be selected, preferably a polyester fiber, a thermoplastic resin fiber such as an acrylic fiber or a nylon fiber, and more preferably a nylon fiber.
When the thermoplastic resin fiber is selected as the material constituting the coating main body, the coating body 1 can absorb and retain the liquid.
In this embodiment, the coating main body 2 is made of nylon fiber.

When a fiber material is selected as the material of the coating main body, it is preferable that the coating main body is configured so that the fiber material is oriented in the axial direction thereof.

By adjusting the porosity and hardness (hardness) of the coating subject, the amount of liquid discharged or outflowing and the feeling of use (for example, a hard feeling of use and the feeling of use) can be adjusted according to the preference of the user. It can be adjusted as appropriate to make it feel soft enough not to bend).
The porosity of the coating subject, particularly the coating subject composed of the fiber material, is not particularly limited, but may be preferably in the range of 35% to 88%, more preferably 50% to 80%.

The shape of the coating main body 2 is not particularly limited, and for example, the cross-sectional shape (cross-sectional shape) orthogonal to the axial direction is shown in FIG. 12 (A) in addition to the circular, elliptical, and polygonal shapes. It can be configured to have a desired shape such as a flower shape or a star shape shown in FIG. 12 (B), but the cross-sectional shape is preferably a substantially circular shape or a substantially elliptical shape, and more preferably a substantially circular shape. Be selected.

In the present invention, the groove extending along the circumferential direction on the outer peripheral surface of the coating main body is within a range larger than an angle of 0 ° and smaller than 360 °, preferably an angle, about the central axis of the coating main body. It is formed within the range of 10 ° or more and 270 ° or less.
When the groove is formed within a range of an angle of 10 ° or more and 270 ° or less with the central axis of the coating main body as the center, the user can simultaneously and more accurately draw a plurality of lines by the action and effect of the groove. It becomes possible to draw, and since the coating body composed of the coating main body has sufficient strength, it becomes more difficult to bend when used.
The groove is more preferably formed within an angle of 20 ° or more and 180 ° or less, further considering the strength of the coating main body.

Therefore, the length of the groove 3 can be selected according to the formation range of the groove 3.
For example, when the cross-sectional shape orthogonal to the axial direction of the coating main body 2 is substantially circular, a groove 3 extending along the circumferential direction is provided on the outer peripheral surface of the coating main body 2 along the axis of the coating main body 2. In the directional view, the circumferential angle formed by both edges of the groove 3 in the circumferential direction is in a range larger than the angle 0 ° and smaller than 360 °, preferably in a range of 20 ° or more and 180 ° or less. Can be formed.

In the present invention, the coating main body 2 constituting the coating body 1 is preferably configured so as not to be easily bent by the pressure at the time of coating or the like from the viewpoint of accurately coating or the like.
Therefore, the ratio of the cross-sectional area of the cross section of the coating body 2 to the cross-sectional area of the cross section (cross section orthogonal to the axial direction) of the coating body 2 before the groove 3 is formed at the position where the groove 3 is formed. Is preferably about 65 to 95%, more preferably about 70 to 95%, and even more preferably about 80 to 95%.
When the cross-sectional area ratio is less than 65%, the coating body composed mainly of the coating tends to be easily bent when used, and when the cross-sectional area ratio is larger than 95%, the coating body is said to be easily bent. The groove becomes shallower, and the action and effect of the groove tends to be less likely to be exhibited.

The width and depth of the groove 3 are not particularly limited, and can be appropriately selected depending on the size of the coating main body 2, the application, and the like.
The depth of the groove 3 is preferably formed so that the coating body does not bend when used as a coating body.
For example, when the groove 3 is formed in the range of 180 ° to 270 °, the depth thereof is preferably relatively shallow. More specifically, the depth of the groove 3 is preferably 0.5 mm or less, or 0.1 times or less the outer diameter of the coating main body.
Further, when the groove 3 is formed in the range of 20 ° to 180 °, the depth may be relatively deep, but it is more preferable from the viewpoint of configuring the coated body so as not to bend easily. It is 0.5 mm or less or 0.1 times or less with respect to the outer diameter of the coating main body.

In FIGS. 1 to 4, a groove having a depth of 0.5 mm is formed with respect to the coating main body having a circular shape having a cross-sectional shape orthogonal to the axial direction and having a diameter of 5 mm.

The groove 3 is preferably formed so that its bottom surface 3a bulges outward in the radial direction in an arc shape, particularly when the cross-sectional shape orthogonal to the axial direction of the coating main body 2 is substantially circular. Orthogonal.
More preferably, when the circumferential angle formed by both edges of the groove 3 in the circumferential direction is 180 ° or less, the curvature of the bottom surface 3a is smaller than the curvature of the outer peripheral surface of the coating main body 2. When the circumference angle is larger than 180 ° and 212 ° or less, the curvature is formed so as to be substantially the same as the curvature of the outer peripheral surface of the coating main body 2, and the circumference angle is 212. When it is larger than °, the curvature is formed so as to be larger than the curvature of the outer peripheral surface of the coating main body 2.
With such a configuration, the ratio of the cross-sectional area of the coating body at the position where the groove is formed to the cross-sectional area of the cross section of the coating body before the groove is formed is in a predetermined range, preferably. Since it is within the range of 65 to 95%, the coating main body and the coating body do not easily bend, and as a result, the groove formation can be performed accurately and precisely, and the groove formation can be performed accurately and accurately in use. It can be applied or the like.

In FIGS. 1 to 4, the coating main body 2 is configured so that the cross-sectional shape orthogonal to the axial direction thereof is substantially circular, and extends along the circumferential direction on the outer peripheral surface of the coating main body 2 on the tip end side. The groove 3 is formed within a range of an angle of 20 ° or more and 180 ° or less with the central axis of the coating main body 2 as the center so that the bottom surface 3a of the groove 3 bulges outward in the radial direction in an arc shape.
Therefore, the inner side surface 3b of the groove 3 has a crescent shape as shown in FIG. That is, the inner side surface 3b is formed so that the width in the radial direction gradually increases toward the central portion in the circumferential direction.

With such a configuration, even when the coating main body is a fiber bundle in which the fibers are oriented in the axial direction and is made of a relatively soft material, the groove 3 is formed to make the fibers outward in the radial direction. In the rib 2b formed so as to project and extend in the circumferential direction, the axial width (interval between the grooves) of the rib 2b formed between the grooves 3 and 3 is, for example, about 0.8 to 1.0 mm. Even if it is short, peeling or the like does not occur.
Therefore, by forming a relatively long and deep groove, such a rib can be formed accurately and precisely even when a relatively long and high rib is formed.

A mechanism will be described in which peeling does not occur in the ribs 2b formed between the grooves 3 and 3 when the grooves 3 of the coating main body 2 constituting the coating body 1 are formed.
In FIGS. 6A and 6B, the circumferential position of one end edge of the inner side surface 3b of the groove 3 is indicated by reference numeral a1, and the circumferential position of the apex is indicated by reference numeral a6. , A3, a4, a5, a6 are arranged in this order with a predetermined interval.

FIG. 6A shows a cross section of a coated body in which a groove is formed by a conventional cutting method.
In FIG. 6A, when the groove is formed by the cutting process, the cutting starts from the cutting start position, that is, the circumferential position a1 to a6.
When cutting is performed from the circumferential positions a1 to a6, the groove depth (machining height) rapidly increases as the cutting is performed.
Therefore, as the depth of the groove increases sharply, the resistance during cutting also increases sharply, so that the ribs formed between the grooves are prone to peeling, and the shape of the ribs is deformed or processed. Burrs are also likely to occur.
In FIG. 6A, the cross-sectional shape of the coating main body 2 at the formation position of the groove 3 has a substantially bow shape that is surrounded by an arc and a chord and projects outward in the radial direction.

On the other hand, also in FIG. 6B, when the groove is formed by cutting, the cutting starts from the cutting start position, that is, the circumferential position a1 to a6, but the cutting is performed from the circumferential position a1 to a6. Even after processing, the change in groove depth is very small.
Therefore, since the load on the fibers forming the ribs formed between the grooves is small, peeling, shape loss, and processing burrs are less likely to occur in the formed ribs.
In FIG. 6B, the cross-sectional shape of the coating main body 2 at the formation position of the groove 3 is substantially circular.

In the ribs, peeling due to falling off of the fibers, shape loss, processing burrs, etc. (hereinafter, also referred to as “peeling, etc.”) are caused by the fiber material constituting the coating main body in the axial direction of the coating main body. It is especially likely to occur when it is oriented.
Specifically, the fibers (materials) oriented in the axial direction of the coating main body are generally cut at the time of forming the groove, and the length per fiber is the axial length of the rib. Since the length is about the same (for example, about 0.8 to 1.0 mm), the fibers having such a shortened length fall off from the coating main body due to an impact at the time of forming the groove, and peeling or the like occurs. ..

The occurrence of peeling or the like depends on the hardness of the coating main body, and since the coating main body is rigid when the hardness is high, peeling or the like tends to be difficult to occur, and when the hardness is low (soft). Since it is easily deformed such as bending, peeling and the like tend to occur easily.

According to the present invention, the rib having a predetermined width (length in the axial direction) can be accurately and precisely formed by preventing or suppressing the occurrence of peeling or the like.
This effect is remarkable when the axial length of the rib is 2 mm or less, more preferably 0.2 to 1.8 mm.
When the axial length of the rib is less than 0.2 mm, the strength of the rib is extremely lowered, and the fibers tend to be peeled off.
When the axial length of the rib exceeds 2 mm, peeling of fibers during groove formation is unlikely to occur, but each drawn line when drawing multiple lines or multiple lines tends to be thick and unbalanced. is there.

The width (length in the axial direction) of the groove is also preferably 2 mm or less, more preferably 0.2 to 1.8 mm, from the viewpoint of drawing a plurality of lines or multiple lines.
When the axial length of the groove is less than 0.2 mm, the distance between the drawn lines becomes too narrow in the plurality of lines or multiple lines, and the drawn lines tend to be connected to each other.
When the axial length of the groove exceeds 2 mm, the interval between the drawn lines becomes large in the plurality of lines or multiple lines, and the balance tends to be poor.

In the present invention, the groove (and the rib provided by this formation) is formed so that its circumferential length becomes long, for example, the circumferential angle formed by both end edges in the circumferential direction is 180 ° or more. Can be done.
Specifically, when the groove 3 is formed so that the circumferential angle formed by both end edges in the circumferential direction is 270 °, it is accurate and precise while suppressing fiber peeling during groove formation. In addition to being able to form ribs, as shown in FIG. 11B, the coating at the formation position of the groove 3 with respect to the cross-sectional area of the cross section of the coating main body 2 before the groove 3 is formed. Since the ratio of the cross-sectional area of the cross section of the main body 2 is within the range of 65 to 95%, the strength of the coating main body 2 is maintained at a predetermined value, and it becomes difficult to bend.

On the other hand, in the conventional general groove formation, as shown in FIG. 11A, when the groove 3 is formed so that the circumferential angle formed by both end edges in the circumferential direction is 270 °, the groove 3 is formed. Not only is it impossible to form ribs accurately and precisely, but also the cross-sectional area of the cross section of the coating main body 2 at the forming position of the groove 3 is extremely small, so that the coating main body 2 is easily bent and used as a coating body. It becomes difficult to apply accurately when using.

Regarding the number of the grooves 3, two or more, for example, 4 to 12 grooves of a required depth can be formed with a predetermined interval in the axial direction of the coating main body 2.
In FIGS. 1 to 4 and 7 to 10, eight grooves 3, 3 ... Are formed in the coating main body 2, and seven ribs 2b, 2b ... Are formed thereby.
When forming a plurality of grooves on the outer peripheral surface of the coating body, the plurality of grooves having different lengths may be formed at predetermined intervals in the axial direction of the coating body.

For example, in FIGS. 7 to 10, the grooves 3, 3, ... Extending along the circumferential direction on the outer peripheral surface of the coating main body 2 have a predetermined interval in the axial direction, and the shaft of the coating main body 2 is provided. It is provided so that the circumferential angle formed by both end edges in the circumferential direction of the groove gradually decreases from the directional base end side to the tip end side.

When two or more grooves 3, 3 ... Are formed so that the bottom surface 3a bulges outward in the radial direction in an arc shape, the grooves 3, 3 ... Are preferably preferred. The positions having the longest lengths in the radial direction of the inner side surfaces 3b, 3b ... Are formed so as to be aligned in a straight line along the axial direction.
With such a configuration, the coating body composed of the coating main body can easily draw a plurality of lines or multiple lines.

Further, in the coating main body, the groove extending along the circumferential direction on the outer peripheral surface thereof is not particularly limited in its configuration as long as it is formed within the predetermined range with the central axis of the coating main body as the center. A plurality of grooves having a required length may be provided at predetermined intervals in the circumferential direction.

Regarding the method of forming the coating body, for example, when a fiber material is selected as the material of the coating body, a bundle of desired fiber materials (fiber bundles) aligned in the longitudinal direction has a cross-sectional shape. The fiber convergent is obtained by heating and compressing with a die having pores having a desired shape, and the obtained fiber convergent is adhesively fixed by impregnation with a synthetic resin to obtain an outer peripheral surface of the long rod-shaped body. In addition, the coating main body can be obtained by forming the extending groove within a predetermined range.

The groove can be formed by the following method.
The long rod-shaped body constituting the coating body is fixed to a predetermined jig or the like and moved laterally, and the bottom surface of the groove formed is in a predetermined direction from the central axis of the coating body in a side view. More specifically, it is necessary for a blade having one or more grooves so as to exhibit an arc shape forming a part of the circumference centered on a point shifted in a direction away from the outer peripheral surface on which the groove is formed. By hitting the outer peripheral surface while rotating it in the circumferential direction at a predetermined angle according to the above, two or more grooves extending along the circumferential direction are formed on the outer peripheral surface in a predetermined angle range about the central axis. be able to.
When the number of grooves in the blade is one, the process may be repeated according to the number of grooves to be formed.

With respect to the coating main body 2, before forming the groove 3 or after forming the groove 3, depending on the use of the coating body composed of the coating main body 2, grinding processing or punching processing may be appropriately performed. By applying a desired processing treatment, a coating portion having a desired shape can be formed.

For example, in FIGS. 7 to 10, the coating main body 2 is cut in advance so that the tip side thereof is reduced in diameter toward the tip portion before forming the groove 3, so that the coating portion 2a is formed. It is configured.

The coating body having such a configuration comes into contact with an object for coating, writing, etc., and is formed to a predetermined length according to the application, and is used for a coating tool or a writing tool for writing, drawing, coating, makeup, etc. It can be used as an applicator of.
Therefore, as shown in FIG. 13, for example, the coating body 1 composed of the coating main body 2 is combined with the relay core 6 and the storage portion 7 filled with ink or the like as needed, and the predetermined container 5 is used. It can be housed inside and used as an applicator 4.

The coating body of the present invention is composed of a long rod-shaped coating main body, and a groove having a required depth of two or more extending along the circumferential direction is formed on the outer peripheral surface of the coating main body at the center of the coating body. It is formed within an angle range of more than 0 ° and less than 360 ° with the axis (axis center) as the center.
Therefore, this coated body is excellent in design, and when applied, it is possible to write both a single line and a plurality of lines on the target, and especially when it is used for cosmetics, such as hair and eyelashes. It is possible to apply cosmetics to a plurality of objects at the same time.
Further, in the coated body, the ribs formed between the grooves can be accurately and precisely formed by suppressing the occurrence of peeling and the like, regardless of the hardness value of the coating body constituting the coated body. It is possible to adjust the feeling of application according to the preference of the user.
Therefore, the coating body can be used in a wider range of applications as a coating tool for writing, drawing, coating, makeup, etc., or as a coating body for writing tools.
