JP3044410U - One ball-point pen core with multiple colors - Google Patents

Abstract

(57) [Abstract] [Purpose] Conventionally, only one color can be produced with the core of one ballpoint pen, so a change lever etc. for changing the color when writing characters etc. Since it is necessary to change it or to change it to a ballpoint pen of another color and write it, it is very troublesome to repeat such actions, but if you use a ballpoint pen with this core, you can change the direction of the ballpoint pen you are holding You can change the color and write as many times as you like. [Structure] Ball chip 1 that can produce different colors
And 2 are embedded and adhered to the tip of the core, and when used, the direction of the ballpoint pen being gripped is alternately inverted 180 ° before use.

[Problems to be solved by the device]

 In the conventional case, only one color is written out from the tip of the ball-point pen body with one core, but a change lever etc. for changing the color frequently when writing characters etc. is often changed. Since it had to be changed or changed to a ballpoint pen of another color, there was a problem that it became very troublesome if such actions repeated.

[0002]

[Means for solving the problem]

 In order to achieve the above object, ball tips 1 and 2 capable of producing different colors are embedded in the tip of the core of one ballpoint pen. Similarly, in the case of a core capable of producing three or four colors with one, the basic principle and usage are the same as the case of producing two colors with one. Also, since the partition plate 3 is attached between the ball chips 1 and 2, the colors emitted from the ball chips 1 and 2 do not mix when writing.

[0003]

[Effect of the invention]

 When the colors emitted from the ball chips 1 and 2 are used alternately, if the body of the ballpoint pen is inverted 180 ° alternately, the colors can be converted easily and instantly.
