Description

The present invention relates to a writing instrument, and more particularly, to a multi-tip writing instrument.

Conventional color ink pens, such as marker pens and highlighter pens, are usually used to draw a note with a thick line or write down the main points, and require a relatively thick pen tip. In most cases, only a single color ink cartridge is used.

However, when actually using it, it is not possible to make it stand out because it is monotonous to display or display with monochromatic ink, but when using multiple colors Because you have to buy a color ink pen for each color, it costs extra money and is very inconvenient to carry around.

As described above, the color ink pen has a thick pen tip and a structure in which a multicolor pen core and ink cartridge are pressed by a plurality of springs, and cannot be used in a colorful manner. Both pen refill heads are provided with only two color pen cores and ink cartridges. When using, remove the caps of both heads and change the pen tip in order before using the two colors. It becomes like this.

In addition, the pen tip of the conventional color ink pen is directly connected to the ink cartridge, so after using it for a long time, the pen tip that has been pressed is pressed and the posture when writing letters is bad. In some cases, the pen tip may be deformed or damaged.

In view of this, the inventor has many years of experience in development and manufacturing in related industries, researched the above-mentioned problems deeply, worked on the research and prototype for a long time, and finally developed multifunctional writing instruments Thus, the purpose of the present invention is to greatly improve the disadvantages caused by the prior art.

The purpose of the present invention is to provide a multi-function writing instrument, which has multiple colors on a single head of pen refill, so that the user can use multiple colors as they are without changing the pen tip of both heads in order. Is possible.

As an embodiment of the present invention, it comprises a pen refill, a color pen set and an erasing pen set, the color pen set is provided on one side of the pen refill, the color pen set includes a pen core holder, a pen tip seat, A plurality of color cores, a plurality of relay pen cores, and a plurality of ink cartridges are provided. The pen core holder is fitted to one end of the pen refill, and the pen tip seat is fitted to the pen core holder.
