Description

[Detailed description of the invention] Conventionally, the front body and the rear body made of hard synthetic resin have a U-shaped recess in the middle part of each inner surface, a groove at the tip, and a semi-cylindrical projection at the rear end. In addition to providing each rod, these front bodies,
The rear body is combined in a so-called belly-to-belt state, and a flat hollow part with both sides open at the middle part, a two-pronged part for inserting the core at the tip, and a small amount of elasticity in the cylindrical insertion part at the rear end. A cap body made of hard material or resin material is attached irremovably, and the proximal ends of the three prongs are glued to each other to form a shaft body, and each color is attached to the flat hollow part. There is a known writing instrument in which a large number of leads are inserted sideways and one of the above-mentioned colored leads is held between the legs of the trifurcated part so that it can be inserted and removed by the elasticity of the legs. In this type of writing instrument, the front ends of the front body and rear body that make up the shaft are simply attached to each other with adhesive at the base ends of the two prongs, so a thick colored core is attached to the three prongs. If it is strongly pinched, the adhesive part will peel off due to pressure from the inside, and the front and rear members will separate from each other, causing the forked part to not only lose its function of balancing the color core, but also to collapse the shaft. There was a risk that it would also cause

The purpose of the present invention is to eliminate such defects and increase the storage capacity of preliminary color cores.
and a rear face body 2 made of a colored opaque hard synthetic resin material. U-shaped recesses 4, 4' are formed at the intermediate part of the inner surface of the rear body 2, and semi-cylindrical protrusions 5, 5' are formed at the tip and rear ends. Rod 6,6
', and the front body 1 and the rear body 2 are inseparably joined together with adhesive (not shown) in a so-called face-to-face state, and a flat hollow part 7 with both sides open is formed at the middle part. The end insertion portions 8, 8' are shaped like a bellows, a sponge sheet 15 is stretched over the rear wall of the flat hollow portion 5, and the insertion portion 8 at the tip is made of a colored opaque hard synthetic material with a slight amount of elasticity. A cap body 9 made of a resin material is irremovably attached with an adhesive (not shown), and a ring body 9' made of a colored opaque hard synthetic resin material is attached with an adhesive (not shown) to the insertion part 8' at the rear end. ) is irremovably fitted to form the shaft body 3, and a downward forked part 10 is attached to the top end of the cap body 9, and a decorative body 16 is attached to the side surface of the ring body 9' to be attached to a pocket I- of clothes, etc. Each clip 11-
- A short cylindrical housing part 18 is formed by extending the L-face edge of the ring body 9' upward, and a cap 19 made of black transparent hard resin material is attached to this housing part 18. The cap is removably attached by the drawing method of back-to-back, and a large number of color cores 12 of each color are inserted into the flat hollow part 7 in a sideways state so that they do not slide and move, and the forked part 10 is both legs 1
Between 3.13' and 13', one of the color cores 14 similar to the color core 12 described above is held in such a way that it can be inserted and removed by the elasticity of both legs 13. It houses the color cores 20 of red, blue, etc. to be used.

In addition, 21 in the figure is a transparent soft synthetic resin cap;
2.22' indicates the entry groove.

Since the present invention is as described, it can be used as a multi-color color pencil by arbitrarily replacing the color core attached to the tip of the shaft and the color core of each color loaded in the spare part. Of course, this is extremely convenient, but especially in the present invention, columnar protrusions 5, 5', 6, 6' are provided at the tips and rear ends of the front body 1 and the rear body 2, respectively. isofrontal body 1
, a cap made of a hard synthetic resin material in which the rear face body 2 is combined in a face-to-face state, and insert portions 8° and 8′ are formed at the tip and rear ends, respectively, and the insert portion 8 at the tip has a small amount of elasticity. The cap body 9 is irremovably attached to the cap, and a ring body 9' made of a hard synthetic resin material is irremovably fitted to the insertion part 8' at the rear end to form the shaft body 3. A two-pronged section]0 is provided, and this
Since the color core 14 and the color core 12 are held between the prongs 10 in a removably inserted manner, even if a thick color core is strongly inserted into the three-prong portion 10, this will not constitute the shaft body 3 as in the above-mentioned known device. This prevents the front and rear double-sided members 1 from acting as a force that causes them to separate from each other, thereby preventing the shaft body 3 from collapsing in shape. A short cylindrical housing part 18 for the colored core 14 is formed by extending the first edge of the ring body 9' upward, and a cap 19 made of a transparent hard synthetic resin material is removably attached to this housing part 18. Since a large number of color cores 12 of each color are inserted into the flat hollow part 7 in a horizontally oriented state, the color cores 14 are more compact than the known ones which only have the flat hollow part 7. The accommodation capacity can be increased, and this has an effect that can certainly far-reach the above-mentioned object of the present invention.
