Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a gripping part in a writing instrument and an applicator, which allows a delicate gripping feeling of the gripping part to be exhibited.

[0002]

2. Description of the Related Art As a typical prior art, a gripping body made of a rubber-like cylindrical member is fixed to a shaft cylinder of a writing instrument.

[0003]

In the above-mentioned prior art, since it is a gripping body simply made of a rubber-like tubular member, it is not possible to reveal a delicate gripping feeling.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to provide a gripping part structure in a writing instrument and an applicator capable of exhibiting a delicate grasping feeling. Gas or liquid or gel or jelly inside
A gripping portion structure in a writing tool and an applicator, in which a deformable tubular gripping body enclosing a shape body is arranged,
A deformable tubular gripping body having a gas, liquid, gel-like or jelly-like body inside is disposed in front of the barrel so that the front end thereof does not move forward, and the front part of the barrel is also provided. A screw is provided on the outer surface, and a screw that is screwed to the screw is provided on the inner surface so that a rotating member is connected to the rear part of the gripping body, and the gripping body can be changed in the radial direction by rotating the rotating member. The second gist is the structure of the grip portion of the writing instrument and the applicator.

Hereinafter, an embodiment applied to a ball-point pen of a writing instrument will be described. The same applies to various writing instruments such as a sharp pencil, a fountain pen and a marking pen, and an applicator such as a cosmetic instrument other than the ball-point pen. Is applicable to. FIG. 1 shows a first embodiment of the present invention, in which reference numeral 1 is a barrel made of synthetic resin, metal or the like.
A reduced diameter portion 3 is provided via a step portion 2, and a front member 4 made of metal, synthetic resin or the like is screwed in front of the reduced diameter portion 3. The rear end 5 of the tip member 4 and the reduced diameter portion 3
Then, the stepped portion 2 forms a recess 6, and the gripping body 7 is disposed in the recess 6. The gripping body 7 has a tubular shape, and is a thermoplastic resin in which a gas such as air, a liquid such as silicone oil or other oil, a liquid such as water, a gel-like body, or a jelly-like body is enclosed. Although it is made of a deformable material such as elastomer, silicone rubber, butyl rubber, or other synthetic rubber, butyl rubber having silicone oil sealed therein is particularly preferable in consideration of reliability of sealing. Further, in order to improve the appearance, the gripping body 7 may be colored in an appropriate color for the enclosed one and / or the enclosed one. Further, the outer shape of the grip body 7 may be variously adopted, such as a rough surface, forming a knurl by a projection or a depression, or forming a large number of small projections.

Reference numeral 8 is a ball-point pen having a ball-point pen tip 9 at the tip and an ink containing tube 10 at the back. or,
This example is an example of a retractable ball-point pen.
Although the drawing in which the rupen tip portion 9 is housed in the barrel 1 is shown, reference numeral 11 is an elastic member for constantly urging the ball pen tip portion 9 into the barrel 1.

Various modifications can be adopted in this example. For example, in this example, the grip body 7 is arranged in the recess 6 of the barrel 1, but the reason is for fixing the grip body 7, and means for fixing the grip body 7, For example, ribs may be formed on the surface of the barrel 1 at the front and rear ends of the grip body 7, a ring member may be fixed and the grip body 7 may be arranged between them, or the grip body 7 may be bonded to the barrel 1 with an adhesive material. And so on.

2 and 3 show a second embodiment of the present invention. The same parts as those in the first embodiment are designated by the same reference numerals. A front member 4 is screwed into the front end of the shaft cylinder 1, and a deformable cylinder in which a rear end 5 of the front member 4 and a front end thereof are filled with gas or liquid inside the front end of the shaft cylinder 1. A gripping body 7 is arranged. A screw 1a is provided on the outer surface of the front portion of the shaft cylinder 1, and a rotary member 12 having a screw 12a on the inner surface is screwed into the screw 1a. It is connected to the back of the car. Therefore, the rotating member 12
When is rotated, the rotary member 12 moves in the longitudinal direction, but the movement of the rotary member 12 causes the grip body 7 to change in the radial direction (see FIG. 3). That is,
The amount of change in the radial direction of the grip body 7 is determined by the moving length of the rotating member 12, and the amount of change in the radial direction of the grip body 7 can be determined according to the preference of the user.
In addition, the shaft cylinder 1 is configured so that the front end of the grip body 7 does not move forward.
In the illustrated example, the rear end 5 of the front member 4 is used as a specific means for that. However, in addition to this, a rib or a step is formed on the surface of the barrel 1. It may be formed, a ring member may be fixedly attached, or the inner surface of the front end portion of the grip body 7 may be adhered to the shaft cylinder 1, and various means can be adopted.

[0009]

The present invention employs a deformable tubular body having a gas, liquid, gel-like or jelly-like body enclosed therein as the gripping body, so that the gripping body can be gripped during writing or application. When doing, the gripping body is subtly deformed, and as a result, a subtle gripping feeling of the gripping portion can be revealed. Also, the second
In addition to the effect that the subtle grip feeling of the grip portion can be revealed, the amount of change in the radial direction of the grip body can be determined according to the preference of the user. Have a positive effect.
