[0014]

[Embodiment of the invention]

 In FIG. 1 showing an embodiment of the present invention, a brush pen F has a pen shaft 1, a batting material 2, and a lid member 3 as its constituent elements. The pen shaft 1 is formed of, for example, a synthetic resin such as polypropylene or the like, and is formed in a cylindrical shape such as a cylindrical shape or a hexagonal shape, and is impermeable to liquid. The pen shaft 1 is elastically deformable in its radial direction. More specifically, the pen shaft 1 is compressed and deformed in the radial direction under the pressing force of the finger, and is elastically returned to the original shape by releasing the pressing force.

The batting material 2 is formed by a rod-shaped fiber bundle in which a large number of synthetic fibers are densely bundled, and has a liquid permeability by a capillary phenomenon, that is, a large amount of liquid can be stored. I have. The batting material 2 is formed by partially welding a large number of synthetic fibers such as polypropylene, for example. The batting material 2 itself has considerable rigidity and is not easily bent and deformed. Has become. The batting material 2 is filled in the pen shaft 1 over substantially the entire length thereof.

The batting material 2 is elastically deformable in its radial direction. That is, the batting material 2 is compressed and deformed in the radial direction under the pressing force of the finger, and is elastically returned to the original shape by releasing the pressing force. As described above, in addition to the fact that the pen shaft 1 can be elastically deformed in the radial direction, it can also be elastically deformed in the radial direction by the fingers even in the assembled state in which the batting material 2 is filled inside the pen shaft 1. Have been. The rigidity of the pen shaft 1 and the batting material 2 is sufficiently secured by the rigidity of the pen shaft 1 and the batting material 2 while the above-described elastic deformation in the radial direction is secured. It is said that bending and other deformations are not easily caused by the external force applied during normal use such as drawing. The rigidity of the assembly of the pen shaft 1 and the batting material 2 is ensured by adjusting the thickness and diameter of the pen shaft 1, adjusting the density of the batting material 2, and adjusting the area where the synthetic fibers are partially welded to each other. And the like.

The tip of the batting material 2 is a pen tip 2a. That is, a part of the batting material 2 is protruded from the tip of the pen shaft 1, and the protruding tip is a pen tip 2a processed into a brush shape by, for example, grinding.

The cover member 3 is made of, for example, a synthetic resin and is fitted tightly to the outer periphery of the pen shaft 1 on the base end side. With this lid member 3, the base end of the pen shaft 1, that is, the opening on the base end side of the pen shaft 1 is closed in a liquid-tight manner. Thereby, the batting material 2 is opened to the outside only through the pen point portion 2a. As shown in FIG. 2, the inner hole 3a of the lid member 3 into which the base end of the pen shaft 1 is fitted is tapered so that the diameter decreases toward the inner part. This is preferable for facilitating the fitting of the member 3 to the base end of the pen shaft 1 and for obtaining a reliable sealing action.

Although the lid member 3 and the base end of the pen shaft 1 can be adhered with an adhesive, it may be difficult to adhere depending on the material of the pen shaft 1. It is preferable that the cover member 3 is attached to the pen shaft 1 base end by tightly fitting the pen shaft 1 base end. Note that the base end of the pen shaft 1 may be sealed with an adhesive alone without using the lid member 3 separately. It is desirable that the base end side of the pen shaft 1 be completely sealed, but even if there is a slight leak, there is no practical problem. In FIG. 1, reference numeral 4 denotes a cap that covers the pen tip 2a when not in use, and is detachably fitted to the outer periphery of the tip of the pen shaft 1.

An example of using the brush pen F according to the present invention will be described. First, before use, with the pen tip 2a immersed in water, the finger holding the pen shaft 1 is repeatedly pressed in the radial direction (repetition of pressing and releasing). As a result, a large amount of water is absorbed and stored in the batting material 2 in the pan shaft 1 through the pen tip portion 2a.

The brush pen in which water is stored in the batting material 2 is used, for example, as follows. For example, when drawing a water color painting, it is possible to attach a paint to the pen tip portion 2a wet with water and use it as a paint brush as it is. In addition, blurring processing can be performed by tracing the already applied paint with the pen tip 2a. When refilling the pen tip 2a with water for the purpose of adjusting the density of paint, etc., the pen shaft 1 may be pressed with the finger holding the pen shaft 1, and this pressing causes the pen shaft 1 to be replenished. The water stored in the batting material 2 is supplied to the pen tip 2a.

When cleaning the pen tip 2a, the pen shaft 1 may be repeatedly pressed strongly to allow a large amount of water stored in the batting material 2 in the pen shaft 1 to pass through the pen tip 2a. . The pen tip 2a is also washed by repeatedly pressing and releasing the pen shaft 1 while the pen tip 2a is immersed in water.

By storing colored ink and paint in the batting material 2, the brush pen F itself is used for applying the color of the stored liquid (it becomes a brush pen dedicated to a specific color). . In addition, ink can be used as a brush pen for sumi-e, using ink instead of water, and can also be used for blurring (water supply) the sumi-e. Further, it can be used for cleaning OA equipment and the like, and the pen tip 2a contaminated by the cleaning is repeatedly pressed by the pen shaft 1 in the radial direction in a state of being immersed in the cleaning water, thereby being cleaned by the cleaning water. It is washed and returned to a clean state. The above-described various uses of the brush pen F according to the present invention are merely examples, and the use of the brush pen F is not particularly limited.

Here, an example of manufacturing the brush pen F shown in FIG. 1 will be described. First, the batting material 2 is formed as a continuous long rod-shaped fiber bundle by partially welding a large number of synthetic fibers using a solvent as shown in, for example, Japanese Patent Publication No. 60-18341. The outer periphery of the long batting material 2 formed in such a rod shape is covered by extruding and molding the synthetic resin constituting the pen shaft 1, and the batting material is covered with the synthetic resin constituting the pen shaft 1. FIG. 3 shows a long first intermediate member T1 formed by coating the second intermediate member T1. This long intermediate member T1 is cut into a length corresponding to the length of the brush pen F, and a second intermediate member T2 obtained by cutting is shown in FIG. The second intermediate member T2 is formed by covering the entire periphery of the batting material 2 with a synthetic resin constituting the pen shaft 1.

Only the distal end of the second intermediate member T2 is processed into a brush shape by, for example, grinding, and the lid member 3 is fitted around the outer periphery of the base end of the pen shaft 1, so that the brush pen shown in FIG. Thus, an electrode F is formed. The brush pen F is obtained by removing the synthetic resin forming the pen shaft 1 from the tip of the second intermediate member T2, and is also a batting material from which the synthetic resin forming the pen shaft 1 has been removed. Numeral 2 constitutes a pen tip 2a processed into a brush shape.

Although the embodiment has been described above, the present invention is not limited to this, and can be appropriately modified within the scope described in the claims for utility model registration. For example, the batting material 2 can be impregnated with a surfactant in advance, and in this case, the effect of separating the liquid from the batting material 2 can be enhanced, and the effect of cleaning the batting material 2 can be enhanced. That is, for example, when washing is performed after using a certain color, the effect of separating a certain color attached to the filling 2 from the filling 2 can be enhanced. The pen tip 2a, particularly the tip of the pen tip 2a, may be processed with a solvent or the like to make it harder than the portion existing in the pen shaft 1 (for improving abrasion resistance and fine writing). Will be preferred). Furthermore, the seal at the base end of the pen shaft 1 can be obtained by fusing the pen shaft 1 and the batting material 2 by heat treatment. Of course, the purpose of the present invention is not limited to what is specified, but also implicitly includes providing what is expressed as substantially preferred or advantageous.
