Description

  The present invention relates to a writing instrument.

  Writing tools are indispensable tools for our daily life. Ballpoint pens and mechanical pencils can be cited as typical writing instruments around us. Many ballpoint pens store a ballpoint pen feeler in a shaft cylinder (see Patent Document 1). Many mechanical pencils have a writing lead feeding mechanism and a writing lead tank stored in a shaft cylinder (see Patent Document 2).

In addition, modern people live with various stresses. In order to relieve such stress and to obtain a psychological healing effect, it has been frequently seen in recent years that a precious stone or a semiprecious stone is placed around us. Some of these precious and semi-precious stones are believed to have some kind of special power, and such stones are generally called power stones. And it is believed by enthusiasts that good results will come from the stone, for example by placing a power stone around it.
In order to place the power stone close, a small power stone processed into a hemisphere or the like may be affixed to the surface of the writing tube as a decorative body.

Writing instruments are frequently used in various scenes of daily life. And writing instruments are often stored and carried with other things, and there are many opportunities for writing instruments to hit other things.
When a precious stone or semi-precious stone is pasted as a decorative body on the surface of a writing instrument, if the decorative body hits or gets caught by another object, the pasted decorative body may peel off. The decorative body that has been peeled off from the writing instrument is small and often lost. In addition, it is a troublesome task to reattach the decorative body that has been peeled off.

When a writing instrument in which a precious stone or semi-precious stone is attached as a decorative body and put on the surface of the shaft cylinder is carried in the pencil case, the decorative body collides with another writing instrument contained in the same pencil case. Then, the decorative body damages the writing instrument that was hit.
The present invention solves the above problems, and the object of the present invention is to prevent the decorative body attached to the writing instrument from falling off the writing instrument. It is to provide a writing instrument that can prevent damage to things.

The decorative body 50 is a precious stone or a semi-precious stone and has a spherical shape. The outer diameter of the decorative body 50 is smaller than the inner diameter of the shaft cylinder 20. The decorative body 50 is formed with a hole 51 passing through the center of the decorative body 50. The diameter of the hole 51 is slightly larger than the outer diameter of the ink containing tube 31 and is a size that allows the ink containing tube 31 to be inserted.
The ink containing tube 31 is inserted through the holes 51 of the plurality of decorative bodies 50. The ballpoint pen feel 30 is housed in the shaft cylinder 20 together with the decorative body 50. The front end portion and the rear end portion of the ballpoint pen feel 30 are supported by the front end portion and the rear end portion of the barrel 20, and the longitudinal center axis of the ballpoint pen feel 30, the longitudinal center axis of the barrel 20, Are consistent with each other.

In the shaft tube 20, a gap 60 is formed between the inner peripheral surface 21 of the shaft tube 20 and the surface 52 of the decorative body 50.
The writing instrument 1 has the configuration described above. Next, the effect which the writing instrument 1 has is demonstrated.
In the writing instrument 1, since the shaft cylinder 20 is transparent, the decorative body 50 in the shaft cylinder 20 can be seen from the outside. For this reason, the user of the writing instrument 1 can see the decorative body 50 whenever he / she holds the writing instrument 1 and can receive psychological healing from the precious stones or semi-precious stones forming the decorative body 50. Moreover, the user of the writing instrument 1 can also enjoy the decorative effect of the decorative body 50.
