DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing implement, and more particularly, to a writing implement using ink, in which an ink liquid and a colorant contained in ink are stored separately from each other. While the liquid is being guided to the writing tip,
The present invention relates to a writing implement in which a coloring agent is added to an ink liquid so that writing can be performed with an ink having a predetermined color at a writing tip.

[0002]

2. Description of the Related Art Conventionally, writing implements using ink include:
Various things are provided. Such a writing implement can be roughly divided into two in relation to ink.
One is that the writing implement itself is not provided with ink, as is the case with a traditional brush, and the ink is attached to the tip of writing, and then writing is performed using the attached ink.

[0003] As such a writing instrument, specifically,
For example, there are a brush, a steel brush, a false pen, and a crow. In the other method, the writing implement itself holds the ink, and the ink held by the writing implement itself is guided to the writing tip for writing. Specific examples of such a writing instrument include a fountain pen, a ball-point pen, a felt pen, a felt-tip pen (marker pen), and a needle pen.

[0004] The ink used in the latter writing instrument is obtained by dissolving or dispersing a dye or pigment in a vehicle (solvent or medium) almost uniformly in advance. Are adjusted so as to exhibit almost the same color when transferred to the writing surface.

[0005]

By the way, in the above-described conventional writing implement, the color of the ink transferred to the writing surface is determined by looking at the color of the ink held therein. This is convenient in this regard. However, in recent years, it has been desired to provide a new writing implement that is completely different from a conventional writing implement.

Therefore, according to the first aspect of the present invention, the ink liquid contained in the ink and the main component of the colorant are stored separately, and the ink liquid is guided to the writing tip. On the way, by forming the colorant so as to be added to the ink liquid, for example, to make the ink liquid colorless and transparent, or to make the color of the ink liquid a color different from the colorant, or The purpose is to provide a writing instrument that can be written with ink that exhibits a predetermined color at the writing tip by making the color of the liquid an extremely light color similar to the colorant, but the appearance is completely different from conventional writing instruments. I do.

According to a second aspect of the present invention, in addition to the object of the first aspect, the colorant is provided between the ink liquid and the colorant in the direction of the ink liquid. By providing a colorant movement direction restricting body for restricting movement toward the ink, it is difficult for the colorant to be mixed into the ink liquid, and a writing instrument that keeps a completely different appearance for a long time The purpose is to provide.

[0008] Further, of the present invention, the invention described in claim 3 provides, in addition to the object of the invention described in claim 1 or 2,
By putting the liquid undissolved in the ink liquid,
In order to make this liquid non-dissolved material visible, and when this liquid non-dissolved material is relatively small, such that the liquid non-dissolved material fluctuates in the ink liquid during writing,
It is an object of the present invention to provide a writing instrument having a very interesting appearance or a writing instrument having an extremely high advertising effect.

[0009]

Means for Solving the Problems (Claim 1) The invention according to claim 1 of the present invention is a writing instrument, which is a liquid for ink (50) and which is colored with the liquid for ink (50). The main body of the colorant (60) is stored separately, and while the ink liquid (50) is guided to the writing tip (70), the colorant (60) is stored in the ink liquid (50). Characterized by being formed to be added to

Here, the "liquid for ink (50)" corresponds to a vehicle of a conventional ink, and means a liquid mainly composed of a conventional ink excluding a dye or a pigment. Further, the “colorant (60)” corresponds to a dye or a pigment of a conventional ink, and mainly includes a portion obtained by removing a vehicle from the conventional ink. That is,
By adding the “colorant (60)” to the “ink liquid (50)”, an ink substantially similar to the conventional ink is adjusted.

Alternatively, a colorless transparent or translucent ink liquid (50) can be prepared by removing a predetermined component from a conventional ink vehicle. Further, for example, by dissolving or dispersing a very small amount of a dye or pigment in a conventional ink vehicle, a colored transparent or colored translucent ink liquid (50) can be prepared. Thereby, for example, it is possible to adjust the ink liquid (50) having the same system as the colorant (60) and a very light color. Further, for example, it is also possible to adjust the ink liquid (50) having a color different from that of the colorant (60) and a very light color. How to adjust the ink liquid (50) depends on what one wants to see and feel.

The vehicle as the ink liquid (50) includes, for example, water, a water-soluble organic solvent, a lubricant, a preservative,
It can be adjusted by appropriately mixing a rust inhibitor, a pH adjuster, an anti-drying agent, a thickener, or an emulsion. As the “colorant (60)”, for example, a dye or pigment of a conventional ink can be used as it is.
Thereby, the solid or high-concentration liquid colorant (60) can be adjusted. Also, for example, a high-concentration liquid colorant (60) can be prepared by dissolving or dispersing an extremely large amount of dye or pigment in a conventional ink vehicle. Also, for example, by dissolving or dispersing an extremely large amount of a dye or pigment in a predetermined component in a vehicle of a conventional ink, a high-concentration liquid colorant (60) can be adjusted. In addition, colorant (60)
How the colorant is adjusted depends on the addition form of the colorant (60) to the ink liquid (50) and the like.

As the dye as the colorant (60), for example, a direct dye, an acid dye, a basic dye, a fluorescent dye, or an edible dye can be used. Further, as the pigment as the colorant (60), for example, an inorganic pigment, an organic pigment, an inorganic fluorescent pigment, an organic fluorescent pigment, or the like can be used. In addition, "the main component of the colorant (60)"
This is a concept that includes all of the coloring agent (60) or most of the coloring agent (60).

Food dyes, inorganic pigments, organic pigments, inorganic fluorescent pigments,
The organic fluorescent pigment will be described in detail in the embodiments of the present invention. The “writing tip (70)” refers to, for example, a pen tip when the writing implement is a fountain pen, and a ballpoint pen tip (71) when the writing implement is a ballpoint pen. Is a felt tip, it means a writing tip made of felt, and if the writing implement is a felt-tip pen (marker pen), it is a writing tip made of a fiber bundle, and the writing implement is a needle pen. In the case of, it refers to a thin tubular writing tip.
Note that the writing implement is not limited to these, and the writing tip (70) is not limited to these.

[0015] The ink liquid (50) and the colorant (6
"The main body of 0) is separated and stored" means that the main body of the ink liquid (50) and the colorant (60) contained in the ink are separately stored inside the writing instrument. Means In addition, "the ink liquid (50) is the writing tip (70)
Colorant (60) becomes liquid for ink (50)
"Is added to the ink liquid (50) in the process in which the ink liquid (50) reaches the writing tip (70).
Is passed through the portion where the solid colorant (60) is stored, so that the solid colorant (60) is added while being dissolved little by little, or the ink liquid (50)
In the process up to the writing tip (70), the liquid for ink (50) passes through the portion where the liquid colorant (60) is stored, so that the liquid colorant (60) is little by little. Means that it is added while being mixed, or that the liquid colorant (60) is directly added to the ink liquid (50) in the process until the ink liquid (50) reaches the writing tip (70). I do.

As described above, the ink liquid (50) and the colorant (60) contained in the ink are separated and stored, and the ink liquid (50) is on the way to the writing tip (70). By forming the colorant (60) so as to be added to the ink liquid (50), for example, the ink liquid (50) can be made colorless and transparent, or the ink liquid (5)
Since the color of (0) can be different from that of the colorant (60), or the color of the ink liquid (50) can be a very light color similar to the colorant (60), the writing tip (70) can be used. In (2), writing can be performed with ink exhibiting a predetermined color, but a writing implement that is completely different from a conventional writing implement can be provided. (Claim 2) In addition, the invention described in claim 2 of the present invention further includes, in addition to the constitution of the invention described in claim 1, a structure in which a liquid for ink (50) and a colorant (60) are provided. , Colorant (60)

In addition, “regulation” refers to preventing the colorant (60) from being mixed into the ink liquid (50) or preventing the colorant (60) from being mixed into the ink liquid (50). This is a concept that includes both. Therefore, the colorant moving direction restricting body (80) is preferable as long as it can prevent 100% of the colorant (60) from being mixed into the ink liquid (50). It is not limited.

The colorant moving direction regulating body (80)
Can be formed using, for example, a valve or a filter in a broad sense. As the filter, for example, a semipermeable membrane (81), a hollow fiber membrane, a membrane filter, a column for liquid chromatography (ion exchange resin), or a moisture-permeable waterproof material (for example, W.U.
