Simple paper writing instrument

Abstract

To provide a simple paper writing instrument that is disposable and suitable for short-term use from the standpoints of manufacture, use, and disposal to solve the problem that conventionally, many writing instruments used in corporate novelty goods and elections have a short lifespan and limited uses, yet are of excessive quality or have a shape that makes them difficult to use.SOLUTION: There is provided a simple paper writing instrument characterized in that any drawing material, such as a ballpoint pen refill, is inserted into a main body assembled from a flat development, and when the drawing material comes into contact with a drawing material stopper inside the main body of the present invention, the position of the drawing material is fixed, so that the product can be used as a writing instrument.SELECTED DRAWING: Figure 4

Description

[Technical field]

[0001] The present invention relates to a simple paper writing instrument that uses ready-made drawing materials. [Background technology]

[0002] Conventionally, there has been a paper writing instrument that holds a pencil lead from the side by friction (see Patent Document 1). There was also a simple writing implement that could be assembled from a flat surface using cardboard and plastic plates. (See Utility Model Document 2.) [Prior art documents] [Patent documents]

[0003] [Patent Document 1] ​Patent No. 4965732​ [Patent Document 2] ​Japanese Utility Model Application Publication No. 62-011689 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional writing implements have the following drawbacks: (A) In many of the above-mentioned background art, the comfort of gripping a writing instrument when assembled from a flat surface is insufficient. (b) In addition, since the structural retention of drawing materials such as pencil lead is achieved by friction from both sides or from above and below due to the material that constitutes the pen body, there was a concern that the drawing material would be pushed back into the pen body due to the pressure of writing when in use. The present invention has been made with the objective of solving the above problems. [Means for solving the problem]

[0005] The main body (1) of the present invention is formed in a flat development (5), and has a drawing material insertion portion (2) and a drawing material stopper (3) inside the main body (1). Any drawing material (4) is inserted into the drawing material insertion portion (2), and the position of the drawing material (4) is fixed by the rear end of the drawing material (4) coming into contact with the drawing material stopper (3) inside the main body (1). A simple paper writing instrument having the above configuration. Effect of the Invention

[0006] This invention, which has a three-dimensional triangular prism shape that feels the same as an everyday writing instrument, but is made from a flat sheet of paper cut out of a development diagram and existing drawing materials, is an invention that can serve as a substitute for simple writing instruments that are used for a short period of time, such as novelties and elections. [Brief description of the drawings]

[0007] [Figure 1] FIG. 1 is a perspective view of the present invention. [Diagram 2] FIG. 2 is a cross-sectional view of the present invention. [Diagram 3] FIG. 1 is a perspective view of the present invention. [Figure 4] FIG. 2 is a perspective view of the present invention. [Diagram 5] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present invention will be described. (a) The main body (1) of the present invention is comprised of a flat development (5). (b) By assembling the main body (1) from the development diagram (5), the drawing material insertion section (2) and drawing stopper (3) are formed inside. (c) The drawing material (4) is inserted into the drawing material insertion portion (2) from the front end of the main body (1). (ii) The rear end of the drawing material (4) inserted into the drawing material insertion portion (2) of the main body (1) comes into contact with the drawing material stopper (3), thereby fixing the position of the drawing material (4) and preventing the drawing material (4) from being inserted further rearward. (e) The drawing material (4) is structurally held in place in the main body (1) by friction caused by contact between the inner surface of the drawing material insertion portion (2) and the drawing material (4) and the rear end of the drawing material (4) being fixed in position by the drawing material stopper (3). The present invention is constituted as described above. When using the present invention, the main body (1) with the drawing material (4) attached is held in the hand in the same manner as when using a writing instrument. [Explanation of symbols]

Claims

1. A simple paper writing implement having a triangular prism-shaped hollow body (1) obtained by folding a flat development (5) made of a sheet of paper, and provided inside the body (1) with a drawing material insertion section (2) corresponding to the outer diameter of a drawing material (4) such as a ballpoint pen refill, and a drawing material stopper (3) that abuts against the rear end of the drawing material (4) to fix its position, and when the drawing material (4) is inserted into the drawing material insertion section (2), the rear end of the drawing material (4) abuts against the drawing material stopper (3), preventing the drawing material (4) from moving rearward, and thereby maintaining the front end of the drawing material (4) at an exposed length suitable for writing.

2. 2. The paper simple writing implement according to claim 1, wherein the drawing material insertion portion (2) is formed by opposing surfaces of the triangular prism-shaped inner wall of the main body (1), and at least a portion of these inner wall surfaces acts as a positioning guide along the outer diameter of the drawing material (4).

3. 3. The paper simple writing implement according to claim 1 or 2, wherein the drawing material stopper (3) has an abutment surface integrally formed inside the main body (1), and mechanically prevents the drawing material (4) from retracting due to pressure when writing when the rear end of the drawing material (4) abuts against the abutment surface.

4. 4. The simple paper writing implement according to claim 1, wherein the drawing material (4) is removable from the drawing material insertion portion (2) by pulling it out toward the front end.
