Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument.
More specifically, the present invention relates to a writing implement comprising a metal pen tip having a metallic glossy color on its outer surface, and a synthetic resin holder for holding the pen tip.

[0002]

2. Description of the Related Art Conventionally, in a writing instrument of this type, a synthetic resin holder having a metal nib at the front end is generally colored in the same color as the ink color or in a less noticeable color (for example, white). . Therefore, in the conventional writing instrument, only the metal nib has a metallic luster (for example, a plating color or a silver color), and the holder does not have the metallic luster. Did not.

Japanese Patent Application Laid-Open No. 7-329484 discloses a metal pen tip, a synthetic resin holder for holding the pen tip, and a metal tip body for projecting the pen tip and the holder to the outside. A ballpoint pen is disclosed in which a metal support cylinder is provided at the front end of the holder, and the support cylinder and the pen tip protrude from the tip body. However, in the conventional ballpoint pen, in addition to the metallic luster of the metallic nib and metallic tip, the metallic luster of the metallic support cylinder provides a series of metallic luster by the pen tip, the support cylinder, and the tip. However, since a metal support cylinder as a separate member is required, the manufacturing cost is increased due to an increase in the number of parts and an increase in the number of assembling steps, and it has been difficult to provide the same at low cost.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has a simple structure and an inexpensive structure which satisfies a sufficient luxury feeling by a series of metallic gloss colors near a pen tip. It is intended to provide a writing instrument.

[Means for Solving the Problems]

(Summary) The present invention relates to a metal nib 2 having a metallic luster color on its outer surface, and a synthetic resin holder 3 for holding the nib 2.
And the outer surface of the holder 3 is colored in a metallic glossy color (claim 1).

The present invention also provides a refill 5 having a metal nib 2 and a synthetic resin holder 3 for holding the nib 2, and the refill 5 is exchangeably housed inside.
A shaft cylinder 6 having a tip body 7 at a front end thereof;
A writing tool 1 having the holder 3 projecting from the tip body 7 to the outside, and having a metallic luster color on the outer surface of the pen tip 2 and the outer surface of the tip body 7, wherein the outer surface of the holder 3 is made of metallic luster. It must be colored (claim 2).

(Metal Gloss Color) The metal gloss color is, for example, an original metal gloss color of a metal material, such as gold, silver, nickel, or the like.
A metallic luster color by a plating layer of chromium or the like, a metal deposition layer of aluminum or the like, a metallic luster color of a coating layer containing a metallic pigment (for example, a metal powder pigment made of aluminum powder or brass powder, a pearl pigment, etc.), or A metallic luster color or the like of a molded article obtained by kneading the metallic pigment in a synthetic resin is exemplified.

(Pen Tip) As the metal pen tip 2 having a metallic glossy color on the outer surface, specifically, a ballpoint pen tip,
Examples thereof include a pipe-shaped pen tip, a fountain pen-shaped plate-shaped pen tip, a plastic pen tip whose outside is protected by a metal cover body, and a pipe-shaped pen tip that protects a pencil lead of a mechanical pencil. Examples of the metal material include a stainless steel material and a copper alloy whose surface is plated.

(Holder) The holder 3 made of synthetic resin is
For example, it can be obtained by injection molding of a synthetic resin such as polypropylene, polyethylene, polyacetal, ABS resin, and polyethylene terephthalate.

As a method for coloring the synthetic resin holder 3 to a metallic gloss color, for example, a method in which a metallic pigment is kneaded in a synthetic resin, a method in which a coating layer containing a metallic pigment is provided on the outer surface, and the like can be cited. . The holder 3 is preferably colored substantially the same color or an approximate color as the outer surfaces of the metal pen tip 2 and the metal tip 7.
For example, when the pen tip 2 has an original metallic gloss color of a metal base such as stainless steel and the tip body 7 has a metallic gloss color by a nickel plating layer, the holder 3 has aluminum powder dispersed in a resin. Examples of the configuration include a synthetic resin molded body.

(Apical Body) The metallic body 7 is made of, for example, a metal material such as stainless steel or brass whose surface is plated, or a synthetic resin. The outer shape of the tip 7 is tapered, and a penetrating hole 71 from which the pen tip 2 and the front end of the holder 3 protrude is formed at the front end.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention / writing implement 1, and FIG. 2 is an enlarged explanatory view of the vicinity of a pen tip 2 in FIG.

(Writing Tool) The writing tool 1 is a ball-point pen comprising a barrel 6 and a ball-point pen refill 5 exchangeably housed in the barrel 6.

(Shaft tube) The shaft tube 6 is made of a metal
(Specifically, a cut piece made of brass having a nickel plating layer on the surface) and a synthetic resin to which the tip 7 is screwed to the front end (specifically, a transparent AS resin) Shaft 8
Consists of The tip body 7 has a conical appearance, and has a hole 71 at the front end thereof from which the pen tip 2 and the front end of the holder 3 protrude.
Is pierced. A tail plug 81 is fitted into the rear end opening of the shaft 8.

(Refill) The ballpoint pen refill 5
Comprises a ball-point pen tip 2 (pen tip), a holder 3 having the ball-point tip 2 fixed to the front end, and an ink container 4 having the holder 3 fixed to the front end.

(Ball Pen Tip) The ball pen tip 2 presses and deforms a metal (specifically, stainless steel) pipe from the outside to form a plurality of inwardly projecting portions. It is a pipe-type ballpoint pen tip that serves as a seat, and a ball is rotatably held at the front end. The outer surface of the ballpoint pen tip has the original metallic luster of stainless steel. In addition, a ballpoint pen tip of a type in which the ball receiving seat is formed by cutting may be used.

(Holder) The holder 3 is obtained by injection molding of a synthetic resin (for example, polypropylene resin) kneaded with aluminum powder. Thereby, a metallic luster color (specifically, silver color) is developed on the outer surface.

The holder 3 is provided with a mounting cylinder 32
And a flange portion 31 are integrally connected to each other.
Is fitted into the front end opening of the ink container 4, and the flange 31 is stopped against the front edge of the ink container 4.
The front outer peripheral surface of the holder 3 is pressed against the inner surface of the hole 71 of the forebody 7.

(Flange) A ball-point pen refill 5 having the holder 3 is inserted through a front end opening of a shaft 8 having a tail plug 81 fitted to a rear end thereof. Screw. At this time, the flange 31 of the holder 3
