Description

[Detailed Description of the Invention] This invention relates to a writing instrument container for storing, for example, a fountain pen or the like.

A rectangular case made of a rigid material is generally used as a writing instrument container to protect the writing instrument from external damage when not in use.

However, such cases are relatively difficult to manufacture, as they are based on common sense shapes and are decorated with various decorations to attract people's attention, resulting in high costs. It became.

Moreover, since it is made of a rigid material, it is relatively heavy, and as a result, it is relatively troublesome to store and take out the writing instrument by opening and closing the case.

This idea was made based on these circumstances, and it has a unique shape that attracts people's attention, and it is extremely easy to manufacture, which reduces costs. It is an object of the present invention to provide a writing instrument container in which it is extremely easy to store and take out writing instruments.

This invention will be explained in detail below using examples.

FIG. 1 is an external configuration diagram showing an embodiment of a writing instrument container according to this invention.

In the figure, there is a substantially spindle-shaped container 1 obtained by rotating an arc of relatively small curvature, and this container 1 is made of, for example, a transparent flexible thin synthetic resin material.

In the direction perpendicular to the axis of this container 1, that is, ■-■ in FIG.
As shown in FIG. 2, the cross-sectional shape of the line is a circular shape with portions IA overlapping each other at the end sides, and a portion of the overlapping portions IA each has a recess pointing toward the center of the circle. Sections 2 and 3 are provided, respectively.

These concave portions 2 and 3 are overlapped and engaged with each other, and as the container 1 deforms,
When the respective recesses 2 and 3 are disengaged, the diameter of the container 1 increases as shown in FIG. 3 due to the elasticity of the container 1 itself.

A writing instrument container having such a shape is formed, for example, as follows.

That is, as shown in FIG. 4a, a transparent flexible material 4 having a thin, almost hemispherical shell shape is prepared, and an imaginary line passing through the center of the circle at the circular end 4A of the flexible material 4 is prepared. A force is applied to two points α and β located on the straight line A in the direction in which they are separated from each other in the radial direction.

Incidentally, recesses 2 and 3 are formed in advance on the surface of the visible material 4 that connects two points of the circular end 4A on a straight line (not shown) passing through the center of the circle and perpendicular to the straight line A.

By applying the force as described above at the two points α and β on the circular end portion 4A, the flexible material 4 is deformed as shown in FIG.

The ends 4B, 4C separated by β are brought close to each other and eventually overlapped with each other as shown in FIG.

In the state shown in FIG. 3, the flexible material maintains its regular state, and in this regular state, the elasticity of the flexible material that occurs around the straight line connecting the two points α and β is As shown in FIG. 2, when the area of the overlapping portion around the shell near each end 4B, 4C is increased, the recesses 2, 3 in the overlapping portion are engaged with each other, and the container is closed. 1 is held with its opening closed.

In the writing instrument container configured in this way, when the container 1 itself is deformed in a direction that reduces the area of the mutually overlapping portions IA of the visibility material 4, the engagement between the respective recesses 2 and 3 is easily released, Thereafter, due to the elasticity of the flexible material, as shown in FIG. 3, the diameter of the container 1 increases and the area of the overlapping portions IA of the flexible material 4 decreases.

Then, by widening the ends 4B and 4G of the flexible material 4, an opening is formed and a writing instrument is stored through this opening.

Thereafter, the recessed portions 2 and 3 are engaged to maintain the closed state of the opening by performing the reverse process to the above-described operation.

In this way, the outer shape of the writing instrument container becomes almost spindle-shaped and unique, making it eye-catching and interesting.

In addition, since its shape is extremely simple and it is constructed as a molded product made of flexible material, it does not require any other parts, making it easy to manufacture and reducing costs. become.

Furthermore, although the flexible material is thin, the container itself maintains sufficient strength, while the opening can be formed extremely easily with a small amount of force to accommodate and take out writing instruments. , it becomes extremely easy to take out.
