BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing implement, and more particularly to a writing implement having a writing implement main body and a cap to be put on the writing implement, the cap having a decorative function and a decorative body representing an ink color or the like attached thereto. .

[0002]

2. Description of the Related Art Many known writing instruments are of a type in which a cap is put on a writing instrument body having a ball-point pen or a mechanical pencil to protect the ball-point pen or the mechanical pencil portion.

For example, in the case of a writing instrument represented by a ballpoint pen, in order to make the color of the ink of the ballpoint pen visible from the outside of the cap, a decorative body of a color corresponding to the color is attached to the cap, and the cap is covered. In this state, the color of the ballpoint pen can be determined even in the state where the ballpoint pen is used.

[0004] In this case, the cap is provided with a decorative body as an indicator of ink color discrimination, but the simplest one is to form a recess at the top end of the cap, and to replace this part with the ink. Colored according to the color,
In the form of attaching a decorative body separate from the cap, the mounting structure is to fix the decorative body corresponding to the ink color to the mounting hole drilled in the cap using adhesive, or to decorate the mounting hole There is known a method in which a piece is press-fitted and attached using the elasticity of a material.

[0005]

In the conventional method of attaching a decorative body, the method using an adhesive is such that the decorative body is attached to the cap while the intended mounting position does not coincide with the decorative body. It is fixed and damages the appearance of the product.In addition, with the decoration mounting structure by press-fitting, there is no problem immediately after the decoration is mounted, but after a considerable period of time the material fatigues and the elasticity is reduced. As a result, there is a problem that the material is pressed into the press-fitted portion, and the decorative body falls off.

[0006] In order to solve the problems of the prior art, the present invention does not use a simple press-fitting method using the adhesion or elasticity of the material, but rather mounts the cap and the decorative body by mechanical coupling. And the work on installation is easy,
It is an object of the present invention to provide a writing implement that employs an attachment type of a decorative body that does not fall off due to aging.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a writing instrument body, at least a cap attached to one end of the writing instrument body, and a decorative body attached to the cap. In the composed writing implement,
The cap includes a mounting hole formed in a top end portion, and a locking rib formed in a space inside the cap and crossing an extension space of the mounting hole. A decorative piece forming a portion, and a pair of locking legs having, at an end thereof, locking claws facing each other integrally with the decorative piece, and the locking rib is housed in a space sandwiched between the locking legs. Then, the decorative claw is fixed to the cap by capturing the end of the locking rib with the locking claw.

[0008]

With the writing implement of the present invention, when the decorative body is applied to the cap, the locking leg of the mounting body is inserted from the mounting hole drilled at the top end, and the locking claw is locked by the elasticity of the material of the locking leg. When the rib is spread by hitting the rib and pushed above the height of the locking rib, the locking claw is locked to the end face of the locking rib, and the decorative body and the locking rib are mounted.
