2. Description of the Related Art Conventionally, in a ball pen as described above, the rear end of the small-diameter portion of the inner hole, which is the inner step of the barrel, is formed as an engaging portion with the front end of the ink storage tube of the ball pen body. An arrangement for projecting and positioning a ballpoint pen body is known.

[0003] Further, forming the barrel of the ball pen from a transparent synthetic resin not only makes the ink color and the remaining amount in the ball pen body visible, but also provides the ball pen with a sense of quality. It is increasingly used because it contributes to improving the aesthetics of itself.

The ball pen body having the ball pen tip attached to the tip of the ink container tube of the ball pen described above is easily stained by the ink contained therein. Ball pens with transparent barrels are
The combination of the transparent barrel and the ball pen body has an aesthetically undesirable point because the dirt on the rupen body is also exposed to the outside. In particular, ink or the like easily adheres to the joint portion between the ink storage tube and the ball pen tip, and often becomes dirty. However, considering the idea of concealing the dirt on this part, if the transparent barrel is made of non-transparent (or low) resin or metal tip, the advantages of the transparent barrel will be sufficient. There was a problem that it would not be exhibited.

The rear end of the ball pen body 2 housed in the inner hole 3 of the barrel 1 comes into contact with a tail plug 11 attached to the rear end of the barrel by appropriate means such as screwing or press-fitting, and ink is stored. The front end 12 of the tube 4 contacts the inner step 7 formed in the inner hole 3 of the barrel 1. As a result, the ball pen body 2 is clamped and fixed by the inner step 7 of the barrel 1 and the tail plug 11.

Here, the ink storage tube 4 of the ball pen body 2
When the joint portion 13 of the shaft pen 1 and the ball pen tip 5 is viewed from the outside of the barrel 1, the light impinging on the radial groove 9 formed in the inner step 7 of the barrel 1 is complicatedly refracted and reflected. Portion 13 is less visible. In particular, in a portion where light is totally reflected, the joint portion 13 becomes very difficult to see. In addition, since the ball-point tip 5 is made of a metal having a glossy surface, the ball-tip tip 5 also has the effect of reflecting light like a mirror, and furthermore makes it difficult to see the dirt on the joint. The inner step 7 in which the radial groove 9 is formed has a tapered shape gradually expanding toward the rear side, and the rear end thereof is press-fitted between the ink storage tube 4 and the ball-point tip 5. Since the portion 14 is also covered, even if the press-fit portion 14 is dirty, the dirt is difficult to see.

FIG. 4 shows another embodiment of the radial groove 9. FIG. 4 is a diagram corresponding to FIG. 3 of the embodiment described above. In the embodiment of FIG. 4, the radial groove 9 does not have a bottom surface as in the example of FIG. 3, but has a V-shaped cross section. Here, the cross-sectional shape of the groove portion 9 can be appropriately determined such as an arc shape, a parabolic shape, or the like. Further, the groove 9 may be formed as a valley between a plurality of protrusions, and in this case, the shape of the protrusion may be a column, a cone, a hemisphere, or the like.

In addition to the above, various modifications can be made without departing from the gist of the present invention. The ball pen body 2 is shown to be prevented from retreating by a tail plug attached to the rear end of the barrel 1, but it is assumed that the ball pen has a bottom and the bottom portion prevents the barrel from retracting. An inwardly protruding portion may be formed at the rear portion of the inner hole 3 of the cylinder 1 so that the inwardly protruding portion prevents retreat. Further, the barrel may be composed of two members, a front part and a rear part, or may have a cap for protecting the ball pen tip portion. The ink stored in the ink storage tube 4 may be a water-based ink or an oil-based ink, and the physical properties such as the viscosity may be any as long as they are used for ball pens.
