Description

[Detailed description of the invention] This is a method for manufacturing nine pens.

That is, as shown in gm*, the fibers of Ataryl Bibaigo were arranged in the center of the real part of the pipe-shaped synthetic resin shaft tube l cut to the required length on the longitudinal center axis. When the plated metal is inserted and supported into the insertion hole H and heated to about 200°C, the tip of the cylinder is compressed into a substantially conical shape. At the same time, the tip of the pen tip 1' is activated, and at the same time the base of the pen tip 2 is activated.
When the shank reaches the inner wall K111 of the tip # of the wrinkled shank tip, the shank 1 is released and opened, and from the rear end of the shank 1, a thick and dark ink-staining rod 3 made of a coarse bundle of synthetic fibers is drawn. Insert it and bring its tip into contact with the inner end of the above-mentioned carp, and then open the rear end of the barrel 1 with a curving 6.

The conventional tip of this type of nine-point pen is made by first press-fitting the tip of a pipe-shaped synthetic resin barrel that has been cut at a maximum IC of 1 m into an internal conical heat-retaining metal ring. Next, a thin and short nib made of synthetic fibers is applied to the tip of the conical shaft nib and inserted into the tip opening of the conical nib. A thick ink-containing stick made of synthetic fiber is inserted into the rear end of the barrel, and the rear end of the barrel is marked with a letter, or a separate Kll is attached to the tip of the barrel. Insert each pen tip into a short and small holding tube such as a carved conical shape, fit the holding tube to the tip of the barrel, and then insert a smearing rod that is thicker and longer than the rear end of the barrel as described above. In most cases, it is inserted and then the rear end of the barrel is plugged.

However, in this way, it is possible to form the tip of the barrel in advance into a tip and insert the pen nibs one by one from the tip opening, or to provide a holding tube separate from the barrel and insert the pen nibs one by one into this. It takes a lot of effort and man-hours to fit the IL charge holding tube into the barrel, which inevitably makes the product expensive, and also prevents the pen tip from moving accidentally or falling off during use, or causing ink to run out. There was a risk that the outflow would not be smooth and unnecessary items would be produced.

However, according to the present invention, in order to achieve the above-mentioned advantages, the tip of the shaft tube, which is made by cutting a synthetic resin pipe to a predetermined length, is made into a substantially conical inner shape and a tip support hole is provided in the center of the inner part. At the same time as the conical tip part is carved with a metal ferrule, a part of the pen nib is welded to the inner wall of the tip opening of the wrinkled tip part, which requires 5 more troublesome steps and man-hours than the conventional method. It is an excellent nine pen that has the great advantage of being able to mass-produce products extremely efficiently because it can be produced quickly with a single-l1 unit, and there is no need to worry about the nib falling off during writing or making it difficult to write. It has the practical benefit of being able to provide this type of nine-pen at a low price, and is a simple yet extremely useful method for manufacturing nine pens of this type.
It is.

When the tip of the barrel 1, including the central protruding part of the C# pen tip, is heated and compressed with a tip holder 4 having a substantially conical inner shape, it is formed into a tip 1' having a substantially conical shape. At the same time, a part of the barrel 1 with the nib is welded to the inner wall of the tip of the barrel, and a thick and long ink-retaining rod 3 made of a bundle of ink fibers is inserted from the rear end of the barrel 1. A method for manufacturing a nine-ben, characterized in that the tip of the armpit soaking stick is brought into contact with the inner end of the pen tip, and the rear end of the barrel l is closely I&5. 3. Details of the invention. Explanation: The present invention provides a narrow and short tip for a felt-tip pen by forming the tip of a pipe-shaped barrel into a conical tip and at the same time fixing it to the inner wall of the tip of the tip. This is a manufacturing method for nine pens that mass-produces cheap mk with high efficiency.The base of the thin and short nib 2, which has Ataryl-based synthetic fibers focused in *, intervenes in the tip. It was inserted and supported into the insertion hole H provided in the center of the real part of the cap 4 with the shaft tip, which had approximately the same internal shape as the cone. When this is done, the shaft cylinder 111
From #Illsui to k, the tip of the shaft cylinder is approximately the same as Ml.
At the same time as the shaft nib @ 1/ is squeezed and formed, the base of the nib 2 is welded to the inner wall of the tip opening of the scissors shaft nib part.Therefore, when the shaft l111 is delaminated and assimilated, the back of the axillary shaft tube is formed. This is obtained by inserting a thick ink-staining rod 3 made of a rough condensing material with a fine grain from the end and bringing its tip into contact with the inner end of the pen nib, and then opening the rear end of the barrel l. be. The tip of the fat shaft tube is first press-fitted into the internal conical heat retaining pin to form a conical shaft tip, and then the threat fibers are tightly focused within the tip opening of the axillary shaft tip. Apply lacquer to each thin and short pen nib and insert it, then insert a thick and long ink stick with comparatively coarsely concentrated ink fibers from the rear end of the barrel. The rear end of the cylinder is tightly plugged, or the pen nib is inserted into a short holding tube such as a conical shape formed from the tip of the barrel, and the pen nib is inserted into the barrel. After fitting into the tip of the barrel, a thicker and longer draining rod is inserted from the rear end of the barrel as described above, and then the rear end of the barrel is sealed tightly. However, in this way, it is possible to form the tip of the barrel in advance into a tip and insert the pen nibs one by one from the tip opening, or to provide a holding tube separate from the barrel and insert the pen nibs one by one into this. Fitting the rear armpit holding tube to the barrel requires a lot of troublesome work and man-hours, which inevitably makes the K14 product expensive, and also causes the nib to move accidentally and fall off during use, or ink to leak out. There was a risk that unnecessary products such as lack of smoothness would be produced. However, according to the present invention, as described above, the tip of the shaft cylinder obtained by cutting one synthetic resin pipe to a predetermined length is formed into a substantially conical inner lacquer MI.
At the same time, a part of the pen nib is melted inside the tip opening of the axillary shaft nib part. Since it can be manufactured in a single factory without the troublesome labor and man-hours of the conventional method, the product can be manufactured extremely efficiently, and it is clear that there are great benefits to the pen nib industry. This invention has the practical benefit of being able to provide an excellent felt-tip pen at a low price that does not cause problems such as slipping out or not being easily marked.[This invention is simple but extremely useful as a method for manufacturing this type of nine-point pen.] 4.
