Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refill for a felt-tip pen which includes an ink storage body for use by being loaded into the barrel of the felt-tip pen, and which is composed of a heel and a nib.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a thin stainless steel strip (1) is rounded in the longitudinal direction, and the thin strip (1) is gradually rolled from an arc shape to a circular shape. The opposite edges of the strip-shaped thin plate (1) are abutted together, and the abutted edges (2) (2)' are mutually argon bombarded to form the required long pipe (3) continuously, and the long pipe (3) is continuously formed. Cut the shaku pipe (3) into predetermined short lengths,
Swaging (8wa) is attached to the tip of this short pipe (4).
gjug) processing to reduce the diameter of the same tip into two stages, a medium diameter part (5) and a narrow diameter part (6), and insert 6 gold gold into the tip and press embossing and riveting the intermediate part. A crimped thermoplastic synthetic plum fat fiber bundle (with a density that efficiently forms a capillary @'fJi elephant) is formed by drawing and removing the core metal (7). 8

Close the tail end of the force with the tail plug (111), and insert the felt nib (Ha of the narrow diameter part (6) of the force into the 9 heel (force) without being removable from its tip, and insert the upper end of this nib + 12). It is inserted into the above-mentioned occlusion body OI, and a cap (1:1) is attached to the tip of the rehir (force), and this cap 0 is detachably attached to the middle diameter part (5).

Claims (1)

[Claims] The tip of a short stainless steel pipe is reduced in diameter into two stages, a medium diameter part and a small diameter part, to form a reheal, and the reheal is made of crimped thermoplastic synthetic resin with a density that efficiently creates capillary action within the same heel. Load an ink storage body made of a fiber bundle, close it with a tail plug at the tail end of the rehir, and insert the nib of the narrow diameter part of the rehir into the tip of the ink storage body, and insert the upper end of this nib into the above-mentioned occlusion. This refill for a felt-tip pen is characterized in that it pierces the body, attaches a cap to the tip of the re-heel, and is detachably attached to the middle diameter of the cap.
