Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an ink drying preventer for hollow pens, etc., which prevents the ink of hollow pens, etc. from drying and also allows the pen tip to be cleaned. It is.

(Prior art) Ink-inducing pens with hollow pens or porous nibs, such as those used for plotters or handwriting, tend to dry out when not in use, and the ink quickly dries out when used due to coagulation of the ink on the nib. It has the disadvantage of not being guided.

Conventionally, in the case of hollow pens, as a means to prevent ink drying, a molded product with an inner shape such that the pen tip fits into the cap (not shown) of the pen body 1, as shown in FIG. 5, has been used. A sealing member made of ordinary synthetic rubber or the like is placed inside the molded product 4, and when not in use, the ink guiding needle 3- of the pen tip 2 can be covered with a cap.
With A pushed up, the tip 3 of the pen tip 2 is pressed against the sealing member.

Also, if you use a hollow pen frequently, please use the 6th pen.
A pen holder like the one shown in the figure may be used.
This pen holder has a water-absorbing member 5 placed below the pen holder body plate on which the pen body 1 is placed, and the water-absorbing member 5 is made to absorb water, and when the pen tip is pierced, it humidifies the body and prevents it from drying out. It is something.

(Problems to be solved by the invention) In the case of the cap type means shown in Fig. 5, the sealing member lacks elasticity and restoring force, and is thin, so the pen tip cannot be bit into it, and the sealing member is simply It is difficult to form a sufficient seal because the pens just touch each other, and even if you use a hollow pen frequently, you have to cap it each time, which is troublesome. Since it is necessary to mold the molded product 4 of the mold, there is a drawback that the cost increases.

In addition, in the case of the moisture-absorbing type pen holder shown in Fig. 6, the diameter of the insertion hole should be adjusted to the pen body 1 in order to vent air.
Since the gap 9 is made larger than that of the pen, it dries easily unlike a sealed method, and it is necessary to constantly replenish water, and water is absorbed from the tip of the nib due to capillary action, causing the ink to become thin when starting to write. There were some drawbacks such as:

It goes without saying that the above-mentioned conventional caps and pen holders do not have the ability to remove ink scum and the like that has solidified on the pen tip.

The purpose of this invention is to eliminate the above-mentioned conventional drawbacks,
Of course, by piercing the pen tip, you can completely seal and prevent the ink from drying out.
To provide an ink drying preventer for a hollow pen or the like, which can remove and clean ink scum, etc. that has solidified on the pen tip by pulling out the pen tip, and allows ink to be guided immediately when the pen is used. It is in.

(Means for Solving Problems) The ink drying preventer for hollow pens, etc. according to the present invention includes a pen holder main body having an insertion hole for inserting the pen body of the hollow pen, etc., and a lower part of the pen holder main body. and a viscoelastic member made of synthetic raw rubber or the like, which is placed on the tray and into which the pen tip is inserted by pressing the pen body inserted through the insertion hole. The tip of the pen tip is sealed by immersing the pen tip into the viscoelastic member, and the pen tip is cleaned by pulling the pen tip out from the viscoelastic member.

(Example) An example of the ink drying preventer for a hollow pen or the like according to the present invention will be described based on FIGS. 1 to 4.

The ink drying preventer for a hollow pen or the like according to the present invention includes a pen holder body 20 having an insertion hole 8 for inserting a pen body 1 of the hollow pen or the like, and a saucer portion disposed below the pen holder body 20. 22, and a viscoelastic member 6 made of synthetic raw rubber or the like, which is placed on the tray portion 22 and into which the pen tip 2 is inserted by pressing the pen body 1 inserted through the insertion hole 8. The pen tip 2 is configured to seal the tip 3 of the pen tip 2 by immersing the pen tip 2 into the viscoelastic member 6, and to clean the pen tip 2 by extracting the pen tip 2 from the viscoelastic member 6. There is.

The pen holder main body 20 is made of transparent synthetic resin and is formed into a cylindrical shape with a lid.The lid part 21 is formed diagonally so that it can hold pen bodies of various lengths, hollow pens 15 for plotters, etc. A required number of the above-mentioned insertion holes 8 are formed in 21. The tray portion 22 may simply be a base plate into which the lower edge of the opening of the pen holder main body 20 can fit, but in the embodiment shown in FIG. The handle 1 of the pen body 1 is placed inside the mounting table 14.
It is designed to be able to store 1. Further, in the embodiment shown in FIG. 2, a space 13 is provided in the mounting table 14 in which a cap 12, an ink tank, etc. can be stored.
, and the receiving tray portion 22 is formed on the top thereof.

The viscoelastic member 6 is a raw rubber-like material having viscosity, and for example, raw rubber with high viscosity can be obtained by controlling vulcanization during the manufacturing process of synthetic rubber. Reference numeral 7 denotes a transparent cylindrical external air blocking lid that is placed over the pen holder main body 20.

When using the ink drying preventer configured as described above, when the pen body 1 inserted through the insertion hole 8 of the pen holder body 20 is slightly pressed, the pen tip 2 will move as shown in FIG. The guide needle 3-A is slightly pushed into the viscoelastic member 6, and its distal end 3 is completely sealed as shown by reference numeral 10 by the viscosity and elasticity of the viscoelastic member 6.
Ink is prevented from drying.

Furthermore, as shown in FIG. 4, when the pen body 1 is pulled out, fiber sludge, solidified ink sludge, etc. adhering to the tip 3 of the nib 2 are removed by the viscosity and elasticity of the viscoelastic member 6, and the pen body 1 is removed cleanly. Cleaned.

Note that, although the above configuration example has been described with respect to a hollow pen, it is also effective in an ink-inducing type pen or the like with a porous nib.

(Effect of the invention) According to the ink drying preventer for hollow pens and the like according to the invention, by pressing the pen body a little while the pen body is placed upright in the pen holder body, the pen tip pierces the viscoelastic member. The tip of the pen tip is completely sealed due to the viscosity and elasticity of the viscoelastic member, and the ink can be reliably prevented from drying.

Further, when the pen body is removed, dust, solidified ink sludge, etc. that may be attached to the tip of the pen tip are removed, and the pen tip can be cleaned.
