Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems that a conventional bamboo pen has a small ink reservoir capacity requiring a frequent ink replenishment, cannot use any selected material excepting bamboo for a pen barrel, because the pen point is monolithic with the pen barrel, and besides, replacement of the pen point of the bamboo pen as expendables is impossible. <P>SOLUTION: An ink reservoir is formed at the pen point of the bamboo pen. In addition, the ink reservoir is, for example, nothing but a gap provided by releasing the outer layer of the skin of the bamboo used as the pen point. In order to enable replacing of the pen point, the method for inserting the pen point into the pen barrel is adopted. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a shape of a bamboo pen used as a writing instrument.

  The shape of a conventional bamboo pen with the unique texture of a natural material is a combination of the pen tip and the pen shaft, as shown in Fig. 2, for storing ink in the middle of the pen tip. The hole of (f) is drilled.

However, according to the above technique, the amount of ink that can be stored is extremely small, and it has been necessary to frequently replenish the ink when writing. In addition, since the pen tip and the pen shaft are integrated, the shape of the pen shaft is limited. In addition, the nib is a consumable item, but cannot be replaced. Accordingly, an object of the present invention is to provide a bamboo pen that can increase the amount of writing in one replenishment of ink and in which the pen tip can be replaced.

In order to solve the above problems, a first invention is a bamboo pen characterized in that a gap for ink storage is provided at the tip of the bamboo pen.
The second invention is a bamboo pen characterized in that the ink storage gap in the pen tip is a gap provided by peeling off a portion of the bamboo skin that is the same body as the bamboo used in the pen tip.
The third invention is a bamboo pen characterized in that the pen tip made of bamboo can be replaced with a pen shaft, and the pen tip can be replaced.

  According to the first invention or the second invention, the bamboo pen tip is provided with a gap for storing ink, so that the amount of writing in one ink supply can be increased. In addition, according to the third invention, the bamboo pen tip can be inserted into the pen shaft and the pen tip can be replaced so that the material and shape of the pen shaft can be freely selected. The pen shaft can be used forever regardless of the life of the pen tip of the bamboo pen.

One embodiment of the present invention is shown in FIG.
The main body 1 of the pen tip of the bamboo pen is made of bamboo.
In order to facilitate understanding of one embodiment of the present invention, FIG. 3 shows the main body 1 viewed from the side.
3A is a bamboo skin peeled from the nib body 1. FIG.
As shown in FIG. 3, the b is deformed to create a gap (b).
This gap (b) is an ink reservoir.
(C) in FIG. 3 is an insertion shaft for making the nib body 1 replaceable.
(2) of FIG. 3 is a pen axis | shaft and the hole (2) in which the said insertion axis is inserted is provided.

"Effect of the embodiment"
According to this embodiment, the amount of ink replenishment is increased by the action of the gap (b) provided in the nib body 1, and as a result, the amount of writing by one replenishment is increased. Therefore, the number of troublesome ink supply during writing can be significantly reduced. In addition, according to this actual form, the pen tip of the bamboo pen is replaceable, so even after the pen tip of the bamboo pen became unusable, it was well adapted to the hand by replacing it with a usable pen tip. You can use the pen axis for a long time. The material and shape of the pen shaft are more flexible and can be used according to the user's preference.

"Other embodiments"
In the embodiment of FIG. 1, the ink reservoir is provided by partially peeling the bamboo skin, but it may be a completely different material with the same shape attached.
The portion to be inserted into the pen shaft in FIG. 3 (c) is obtained by processing a bamboo portion that is the same body as the pen tip in the embodiment of FIG. 2, but may be a portion that is processed with another material.

It is a perspective view showing one embodiment of this invention. It is a perspective view which shows a prior art. It is sectional drawing which shows one Embodiment of this invention.
