Description

[0001]
BACKGROUND OF THE INVENTION
This invention is concerning pen, the pen tip used for various writing instruments and their writing instrument, such as marking pen.
More specifically, it relates to a writing instrument with playability and playfulness and its nib, not a single point of practical use, and belongs to the writing instrument manufacturing technology.
[0002]
[Prior art]
For sign pens, marking pens, line markers, and painting pens, the pen tip color and the ink color to be written are standardized so that the color you want to write can be selected easily. The
Normally, a nib made of a bundle of fibers often used for these purposes should have a high degree of whiteness (high brightness), and when the ink has soaked into the nib, the color of the ink becomes clear at the nib portion. that has been configured to eliciting.
However, in the case of a nib made of a plastic molded body , the plastic molded body is colored in advance in the same color as the ink for writing, or white, colorless or milky white.
[0003]
Among them, the nib made of fiber bundles is said to have a higher commercial value when it is white than the colored nib, but the nib is given various characteristics according to the application. However, depending on the material used, there are some materials that are not white and are colored even though excellent characteristics are obtained, and are restricted in use.
[0004]
For example, oil-based pens that use acrylic fibers are suitable for the hardness and chemical resistance of the writing tip, but acrylic fibers turn yellow or brown when heated in the nib manufacturing process. Inevitable to do.
For this reason, the discolored pen tip is based on the above-mentioned concept and is used for general writing or dark oil-based pens, such as when blackish (low brightness) ink is used, or when the discharged ink is used as a pen tip. The current situation is that the use is limited when the color is the same as that of the color.
[0005]
[Problems to be solved by the invention]
In any case, a writing instrument using a pen nib main body made of a fiber bundle or a plastic molded body or a pen nib thereof is usually charged with a white or colorless object having a high lightness in the writing main body constituting the writing instrument .
Therefore, the ink filled in this writing main body penetrates into the pen tip main body and is only dyed in the same color as the filled ink. It lacked the freshness (playability, fun, playfulness) of writing.
[0006]
In view of the present situation, the present invention examines a method for imparting freshness (playability, fun, playfulness) to writing to a conventional writing instrument that is functional and practical, and is practically equivalent, with playability and playfulness. I studied hard to provide a writing instrument .
As a result, by changing the color of the pen tip constituting the writing tool and the color of the ink discharged from the pen tip, a highly playable writing instrument that gives a sense of freshness and satisfies playfulness is obtained. The present invention has been found and the present invention has been completed.
[0007]

That is, the invention according to claim 1 of the present invention is
When configuring a pen with a cylindrical writing main body with an ink reservoir and a pen tip main body that supplies ink in the ink reservoir to the writing end by capillary action,
A pen characterized in that the nib main body is colored in a hue different from the hue of ink filled in an ink reservoir.
[0008]
The invention according to claim 4 of the present invention is
When configuring the nib main body that supplies the ink in the ink reservoir built in the cylindrical writing main body to the writing end by capillary action,
The pen nib is characterized in that the nib main body is colored in a hue different from the hue of the ink filled in the ink reservoir.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the pen tip of the writing instrument is not only dyed with ink in the ink reservoir built in the writing main body, but is also colored in a hue different from the hue of the ink filled in the ink reservoir. Is.
[0010]
With such a configuration, it is possible to obtain a highly playable writing instrument and its nib that are rich in surprise, give a fresh feeling, and satisfy playfulness .
Therefore, there are no particular limitations on the type of ink and the material and structure of the nib main constituent of the nib, but it is often used in writing instruments such as sign pens, marking pens, and line markers and painting pens. It is preferable to use a nib main body composed of a bundle of fibers in which synthetic resin filaments and slivers are converged and bonded, since the above effect becomes clearer.
[0011]
The filaments (long fiber type) and sliver (short fiber type) that form the fiber bundle described above are prepared by applying a melt or melt of a thermoplastic synthetic resin such as polyester, nylon, or acrylic to a die at a predetermined pressure. The material is obtained by supplying the material, and the material is appropriately selected depending on the application and required characteristics.
[0012]
The effect that occurs when the ink filled in the ink reservoir built in the writing subject is different from the color of the pen tip used in the writing subject is visual, so the pen tip that writes bold or bold lines. If so, it is possible to appeal to the eye more strongly, and the effect intended by the present invention is greatly achieved.
[0013]
In particular, since the effect due to the difference between the ink color of the ink reservoir and the color of the pen tip is achieved by making a difference in color difference, hue, and brightness, it is preferable that the difference is large. Is explained using a Munsell hue circle and a brightness table.
[0014]
For example, using a nib mainly composed of a fiber bundle colored so that the lightness is 2.5 or less (for example, dark gray to black), preferably 2 or less (for example, reddish black to very dark red), When using a light color ink (for example, yellow with a lightness of 8), even if the ink oozes out to the nib, the color of the nib mainly does not get dyed by the color of the ink and always looks black or blackish, The color of the ink is hardly visible .
However, since the ink for writing discharged from the tip of the nib main body is not black but yellow, fresh surprise to writing occurs, and the playability is high.
[0015]
Further, the nib main body composed of a bundle of fibers is colored chromatic and has a lightness of 2.5 or more, preferably 2.5 or more and 8.5 or less, more preferably 3 or more and 8 or less. By using a light-colored ink, the color of the pen nib main body in which the ink has spread and the color of the discharged ink are different, for example, the pen nib main body colored yellow and the Munsell hue ring in substantially symmetrical positions with yellow, by combining a blue ink, pen mainly by the effect of subtractive ing to look green.
At that time, the ink to be written remains blue, and a fresh surprise to the writing arises, which increases playability.
[0016]
Furthermore, when the color of the nib principally and the color of the ink for writing are set to colors that are close to each other, the color of the nib is close to black with a lightness of 2 or less, even in combination of those having high brightness. Therefore, it is possible to make a situation where ink with high brightness is written from the black nib.
[0017]
【Example】
Hereinafter, that describes an embodiment of a nib used in a writing instrument and the writing instrument of the present invention.
Note that the writing instrument 1 of the present invention has a tail end portion closed, and as shown in FIG. 1, the tip opening portion is reduced in the axial direction to form a pen tip holding portion 2a. An ink reservoir 5 is fixed inside a thin cylindrical writing main body 2, and a pen nib main body 4 is provided in the pen nib holding part 2 a through a holder 3 so that a base end portion thereof is in contact with the ink reservoir 5. It is a thing.
[0018]
<Example 1>
A nib main body 4 prepared by converging polyester fibers and using urethane resin as a binder is black dye (manufactured by Nippon Kayaku Co., Ltd .; Kayalon / Polyester / Black / ECX300) 3.0% (based on fiber mass%), dyeing assistant The dyeing was carried out in a dyeing bath having an agent (salt) of 0.5 g / L, a bath ratio of 1: 100, and a pH of 4.5, at a temperature of 135 ° C. for 30 minutes.
In order to wash away the excess dye of the nib main body 4 that had been dyed, reduction cleaning was performed using a soaping agent at a temperature of 80 ° C. for 20 minutes to obtain a black nib having a brightness of 1.5.
When writing on blank paper, the writing instrument 1 was made by combining the writing main body 2 filled with yellow ink having a color tone of yellow and a lightness of 8 with the pen tip colored in black of the lightness of 1.5.
The writing instrument 1 has an effect of subtractive color mixing. The pen tip was black with a lightness of 1.5, but the ink color to be written was yellow with a lightness of 8.
[0019]
In other words, the obtained writing instrument 1 is such that yellow (lightness 8) ink with extremely different hues is discharged from a black (lightness 1.5) pen tip, betraying conventional common sense, and visual effects. Is large, produces a fresh surprise for writing, has high playability, and is playful.
[0020]
<Example 2>
The nib main body 2 similar to that of Example 1 was dyed with a blue dye (manufactured by Katsura Fine Goods; Cole Die Hot F71 Sax Blue) to obtain a nib colored with a lightness of 5 in blue.
When writing on blank paper, the writing main body 2 filled with yellow ink having a color tone of yellow and having a lightness of 8 was combined with the pen point colored in blue of the lightness of 5 to obtain a writing instrument 1.
The writing instrument 1 had a subtractive color mixing effect, and the pen tip was green with a lightness of 5 while the ink color to be written was yellow with a lightness of 8.
[0021]
That is, the obtained writing instrument 1 is such that yellow (lightness 8) ink having a different hue is discharged from the green (lightness 5) pen tip .
Similar to the first embodiment, the conventional common sense is betrayed, the visual effect is great, fresh surprise to writing is generated, the playability is high, and the playfulness is high.
[0022]
In order to make the nib part green, not only the blue nib and yellow ink can be combined, but the nib part can also be made green by combining the yellow nib and blue ink. The
Further , even when the pen tip portion is green, it is possible to make a pen with yellow ink to be written or a pen with blue ink to be written.
[0023]
<Example 3>
When writing on white paper, the writing instrument 1 was formed by combining the writing main body filled with red ink having a color tone of red and lightness 4 with the pen tip colored in blue of lightness 5 used in Example 2.
The writing instrument 1 had a subtractive color mixing effect, the blue pen tip was black with a lightness of 2, and the ink color to be written was red with a lightness of 4.
[0024]
That is, the obtained writing instrument 1 is such that red (lightness 4) ink having a different hue is discharged from a black (lightness 2) pen tip .
Similar to the first embodiment, the conventional common sense is betrayed, the visual effect is great, fresh surprise to writing is generated, the playability is high, and the playfulness is high.
[0025]
In this way, when the pen tip color and the ink color are close to each other, even if the lightness is 2.5 or more, the pen tip color is 2.5 or less due to the effect of subtractive color mixing. The color of the ink or the color of the nib can be made different.
[0026]
In this embodiment, the nib main body is made of a fiber bundle, but the same can be obtained by forming the nib main body with a plastic molded body and coloring the outer peripheral surface of the nib main body. The effect can be obtained.
[0027]
【The invention's effect】
In the writing instrument of this invention, ink different from the color of the nib is discharged from the colored nib, and writing is performed, resulting in visual interest that breaks the conventional wisdom, and a fresh surprise to writing. It is a pen that enhances creativity, playability and satisfies playfulness, and has the effect of greatly expanding its application as a hobby added to a conventional product with a single point of practical use.
[0028]
Furthermore, according to the present invention, there is also an effect that the pen tip made of acrylic fiber whose use is limited despite its excellent characteristics can be used for various writing instruments based on a new view. .
