【Example】

 The figure shows a line marker according to an embodiment of the present invention. First, the shaft cylinder 1 is made of aluminum and has upper and lower ends opened, and female screws 5 are provided on the inner surface of the upper end and the inner surface of the lower end, respectively. The crown 2 and the base 3 provided with the female screw 5 and the male screw 6 which can be screwed thereto are respectively joined to the upper and lower ends of the barrel 1. That is, the crown 2 and the base 3 are detachable from the barrel 1. The crown 2 and the base 3 are also made of aluminum, which is the same as the barrel 1. Also, an aluminum clip 4 is attached to the shaft cylinder 1.

A refill 7 is housed inside the barrel 1. The refill 7 has a pen tip 8 protruding from the base 3 screwed to the lower end of the barrel 1.

The crown 2 screwed to the upper end of the barrel 1 houses a cap 9 for a refill 7 inside. The cap 9 exposes the head slightly from an opening 10 provided in the head of the crown 2. Note that a spring 11 is interposed between the cap 9 and the refill 7.

The cap 9 of the refill 7 is colored in the same color as the ink. Therefore, the head of the cap 9 exposed from the opening 10 of the crown 2 serves as a color display section for ink.

As shown in FIG. 3, the refill 7 is provided with the pen tip 8 sealed with a cap 9, and the cap 9 is removed when the pen tip 8 is stored in the barrel 1. In the conventional line marker, the cap removed from the refill was not used and was discarded. However, in the present invention, the cap 9 removed from the refill 7 is not discarded and is effective for displaying the color of ink as described above. It is used for

As shown in FIG. 1, a cap 12 for an aluminum writing instrument body which is put on the base 3 to seal the pen tip 8 when not in use and which is removed from the base 3 and put on the crown 2 when writing is used. As shown in FIG. 4, the writing instrument main body cap 12 has a vent hole 13 formed in the head thereof. An inner cap (not shown) for sealing the pen tip 8 is provided inside the writing instrument body cap 12. The ventilation hole 13 prevents suffocation even if the throat is clogged by accidentally swallowing the writing instrument body cap 11.

[0011]

[Effect of the Invention] The present invention is as described above. Since the color display of the ink can be performed by using the cap 9 of the refill 7, no special color display parts are required, and the number of parts can be reduced. An increase in cost due to an increase can be avoided. Also, while the refill cap is conventionally discarded, the present invention effectively utilizes the cap 9 of the refill 7 for color display without discarding it, thereby eliminating waste of resources and being extremely useful. is there.
