Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the structure of a marking pen, and more particularly, to a marking pen suitable for using water-based ink and having a wide tip.

(Prior art) A marking pen is made by loading an ink-retaining material such as a non-woven fabric into a container and infiltrating it with ink, and attaching a tip material to the mouth end of the container. Writing or drawing is done using ink that soaks into the pen, and depending on the width of the tip, it can be broadly divided into a wide pen type and a narrow pen type.

(Problem that the invention attempts to solve) Among this type of marking pen, a broad type marker that can be applied evenly over a wide area is often used as a marker for so-called professionals such as graphic designers. This type of marker is usually an oil-based marker that uses a xylene-based solvent, and when applied to a copy using a copying machine, the ink in the marker dissolves the toner, resulting in poor image quality. Therefore, consideration has been given to using water-based ink in a broad-type marking pen.

By the way, in the broad type, the ink-retaining material is made of acetate, and the chip material is made of wool felt, so if it is soaked with water-based ink using an alcohol-based solvent, the ink-retaining material is made of acetate. Experiments showed that the material shrunk and had poor ink retention, while ink did not flow well (poor permeability) with wool felt tips.

(Means for solving the problem) This invention was made in view of the above circumstances.
The purpose of this paper is to propose an improved structure of a marking pen suitable for use with a broad-type marking pen using water-based ink.

That is, the present invention provides a marking pen in which the ink-retaining material is made of wool felt and the tip material is made of polyester.

(Example) The marking pen of the present invention will be explained below based on the drawings. In the present invention, as shown in FIG. The container 1 is infiltrated with dissolved water-based ink, and a chip material 3 is attached to the mouth end of the container 1.
When not in use, cover with a cap (not shown).

The ink holding material 2 is made of wool felt. In this way, when the ink retaining material is made of wool felt, it is possible to take advantage of the property that conventional wool felt chips have poor permeability to aqueous ink. That is, the tip of a marking pen is required to have appropriate self-wetting properties (penetration) so that the ink in the container can be easily applied to the object to be drawn. On the other hand, since the ink-retaining material is initially filled with ink, ink-retaining properties are important, and self-wetting properties itself are not required. Rather, the poor permeability of wool felt means that if it is filled with ink, it will function to promote the supply of ink to the chip material without retaining it. It is. Further, unlike conventional acetate felts, wool felt does not shrink, so it has the advantage that ink retention is not impaired.

The chip material 3 is of a broad type and is made of polyester. This chip material 3
The buried end thereof is in contact with the ink retaining material 2 as in the conventional type. As described above, when polyester is used as the tip material, the wetting property of water-based ink is good, and the result is that no blurring phenomenon occurs when using a marking pen.

(Effects of the invention) As explained above, in the present invention, the ink retaining substance is made of wool felt and the tip material is made of a wide tip made of polyester, thereby obtaining a marking pen suitable for water-based ink. be able to. As described above, when a conventional marking pen for oil-based ink is simply filled with water-based ink containing an alcohol-based solvent, a phenomenon of blurring occurs during use, but according to the present invention, such inconvenience does not occur. A marking pen can be used.
