In this felt pen, felt cores for bold and thin letters are inserted into both ends of a body made of synthetic resin and fixed with a connecting member, and the body between the felt cores at both ends is impregnated with ink, etc. It is packed with. However, the synthetic resin body has many problems in terms of the barrier property of the ink stored inside or the printing of the outer surface. Therefore, a felt pen having a body made of Al was considered. As a body of a felt pen made of Al, there is one conventionally shown in FIG.

絞部50aの外周に雄ネジ50bを形成するものである。A method of manufacturing a body of such a felt pen is to form a cylindrical container having an open end at one end and an integrally molded bottom end at the other end by impact-molding an Al slag. A necked portion 50a is formed on the end of the necked portion, and a male screw 50b is formed on the outer periphery of the necked portion 50a. After that, the body 50 at the end on the sealing side is cut to form an opening, and a necked portion 50a is formed by performing necking processing on this opening, and a male screw 50b is further formed on the outer periphery of the necked portion 50a. Is. That is, the body 50 of the conventional felt pen is one in which both ends of a hollow cylinder are squeezed by necking to form a narrowed portion 50a, and a male screw 50b is formed on the outer periphery of the narrowed portion 50a.

う問題点がある。Problems to be Solved by the Invention However, in the conventional body 50 of the felt pen made of Al as shown in FIG. 3, there is a limit to the narrowing diameter at both ends, and the narrowing diameter is small, so it is extremely thin. It is difficult to directly attach the felt core to the body opening 50c. Further, when the diameter of the throttle portion is small, applying the inner surface paint to the inner surface of the throttle portion 50a with the external thread cut off cannot be completed because the internal surface is wavy due to the formation of the external thread. There was a flaw. Further, the method for manufacturing the body of the felt pen not only requires a large number of conventional manufacturing steps, but also has a problem that the Al material is wasted in the manufacturing process.

かつ製造過程においてAl材料の無駄がない。Operation The operation of the present invention having the above-described configuration will be described. Mouth 1a for attaching felt core 6 for extra-fine books
Can utilize the Al tube production line that has been conventionally used. Further, it is possible to easily manufacture even the mouth portion 1a having an extremely small diameter. Further, as shown in FIG. 2, an extremely fine felt core 6 can be directly inserted into the mouth portion 1a and fixed. In addition, the mouth shaped in this way
As shown in FIG. 1, the inner surface of 1a is flat, so that it is easy to apply the inner surface of the mouth 1a. Then, according to the method for manufacturing a felt pen according to the present invention, the mouth portion 1a is formed by simultaneous molding at the time of impact molding. Further, unlike the conventional case, it is not necessary to make a container having one end opened and the other end integrally molded with the body part and having a sealed bottom portion, and then it is not necessary to cut and open the sealed bottom portion, so that the number of manufacturing steps is small,
Moreover, there is no waste of Al material in the manufacturing process.

きるだけでなく、外面の印刷が容易で美麗である。FIG. 1 is a drawing showing an embodiment of the body of the felt pen according to the present invention. In FIG. 1, 1 is the head of the Al tube. The head 1 is composed of a mouth 1a, a male screw 1b screwed on the outer periphery of the mouth 1a, and a shoulder 1c. Then, a hollow body portion 2 which is continuously punched from the shoulder portion 1c at the same time as the head portion 1 is formed by integral molding with an impact press. A neck portion 4 is formed inward from the body portion opening 3 by a certain width from the body portion opening 3 by necking, and a male screw 4a is formed on the outer periphery of the neck portion 4. The body 5 of the felt pen is assembled in the state shown in FIG. That is, the felt core 6 for fine writing is inserted into the mouth portion 1a of the body 5 of the felt pen. The rear end of the felt core 6 contacts the ink-impregnated cotton 11 housed in the body 2, and the front end is the male screw 1b of the mouth 1a.
It is fixed by the support portion 8a of the connecting member 8 screwed to the. On the other hand, a felt core 7 for bold writing is inserted into the body opening 3 via a ring 10 fixedly provided in the body opening 3. The rear end of the felt core 7 contacts the ink-impregnated cotton 11 like the felt core 6, and the front end of the felt core 7 is the male screw of the throttle 4.
It is fixed by the supporting portion 9a of the connecting member 9 screwed to the 4a. In this way, felt cores 6 and 7 fixed at both ends
Caps 12 and 13 are covered on the tip of the. Since the body 5 of the felt pen according to the present invention is made of Al, unlike the conventional body of a felt pen made of a synthetic resin, the barrier property is perfect and not only can all kinds of ink be used, but also the outer surface Easy to print and beautiful.
