Abstract

(57) [Summary] [Purpose] A pen tip is given elasticity and at the same time has flexibility by putting an elastic substance into the top or inside of the head of a ballpoint pen and an aqueous ballpoint pen. When using on a hard material, there is no need to place a mat or rug under the paper, and the writing is smoother. The present invention is characterized in that a resilient substance is put into the inside of the top of a ball-point pen or an aqueous ball-point pen or in a main body so that the pen tip has elasticity.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention is a ballpoint pen that contains a resilient substance inside the ballpoint pen body.

[0002]

[Prior art]

 Conventional ball-point pens do not have a resilient pen tip and do not taste good.

[0003]

[Problems to be solved by the invention]

 This had the following disadvantages: (B) When writing on a hard material, the writing felt very repulsive and very bad. (B) When writing on hard materials, a mat or a rug was required under the paper.

[0004]

[Means for Solving the Problems]

 Put a resilient substance into the ballpoint pen body.

[0005]

[Action]

 By placing the elastic substance (1) in the ballpoint pen body, the pen tip can be given elasticity and the writing taste can be flexible.

[0006]

【Example】

 Hereinafter, practical examples of the present invention will be described with reference to the drawings. An elastic substance (1 in the enlarged view of FIG. 1B) is put into the ballpoint pen body (in the circle of FIG. 1A). Note that the elastic material may be a cylindrical rubber, a spring, or the like. However, in the case of putting rubber, it is necessary to make a hole in the center so as not to hinder the flow of ink, and to maintain ventilation. Therefore, a ventilation hole such as () is required in the cap part.

[0007]

[Effect of the present invention]

 The configuration of the present invention is as described above. By adding a resilient substance (1), it is possible to make the pen tip resilient and to enjoy a flexible writing taste that could not be enjoyed with the conventional one. it can.

[Correction contents] [Detailed description of the invention]

[0001] in this invention are ball-point pen and parietal Internal or body of the aqueous ballpoint pen, put substances resilient, a ball pen and aqueous ballpoint pen was inelastic nib.

[0002] of the ball-point pen and aqueous ball-point pen, bullet power resistance to the pen tip was not good wrote taste without.

A resilient substance is placed inside the crown or body of ballpoint pens and aqueous ballpoint pens .

[0005] By putting an elastic substance (1) inside the top of the head of the ball-point pen and the water-based ball-point pen or in the main body , the pen tip can be made elastic and the writing taste becomes flexible.

Hereinafter, practical examples of the present invention will be described with reference to the drawings. The elastic substance may be a columnar rubber, a spring, or the like . When the elastic substance (1) is put in the top of the ballpoint pen or the water-based ballpoint pen (in the circle in FIG. 1A). Has the configuration shown in FIG. 1B. However, when a columnar rubber is inserted, it is necessary to make a hole in the center so as not to hinder the flow of ink, and to maintain ventilation, and a vent hole (FIG. 1b) is required also at the top of the head. When a spring is used as a resilient substance in the main body ( inside the circle in FIG. 2A), the resilient substance (1) is held by the projections (FIG . 2B). (FIG. 2B) .
