Embodiment Construction

[0044] Such as figure 1 As shown, the ballpoint pen according to the first embodiment includes an ink storage tube 10 storing ink 15 and a ballpoint pen tip 20 attached to the tip of the ink storage tube 10 . The ink storage tube 10 and the ballpoint pen tip 20 can be directly connected, or can be connected together via a connecting part (not shown). Moreover, although a ballpoint pen generally includes a barrel (not shown) for accommodating a ballpoint pen refill composed of the ink storage tube 10 and the ballpoint pen point 20, the ink storage tube 10 may also serve as the pen barrel.

[0045] Such as figure 2 As shown, the ballpoint pen tip 20 includes a ball 101 and a ball support portion 111 for supporting the ball 101 . The ball support portion 111 is formed of a material such as ferritic stainless steel, and includes a ball support chamber 113 for supporting the ball 101 and an ink passage 114 for supplying ink. The ball support chamber 113 is a concave portion for...

Abstract

The invention discloses a ballpoint pen point and a ballpoint pen. The ballpoint pen point comprises a ball bead (101) and a ball bead support part (111) which supports the ball bead (101) to rotate freely, wherein the ball bead (101) is provided with a main ball bead body (102) and a first carbonaceous membrane (103) which is formed by coating the surface of the main ball bead body (102); the first carbonaceous membrane (103) is provided with carbon atoms and oxygen atoms bonded with the carbon atoms; and a ratio of the carbon atoms bonded with the oxygen atoms on the surface of the first carbonaceous membrane (103) relative to all carbon atoms on the surface of the first carbonaceous membrane (103) is higher than 0.1. According to the invention, the ballpoint pen point which is provided with the ball bead and the ball bead support part with less possibility of abrasion, and has a good writing characteristic for a long time is provided.

Description

technical field [0001] The present invention relates to a ballpoint pen tip and a ballpoint pen, and more particularly to a ballpoint pen tip and a ballpoint pen having a ball covered with a carbonaceous film. Background technique [0002] A spherical ball for a ball-point pen (hereinafter simply referred to as a ball) is attached to a tip of a ball-point pen used as a writing instrument. The ink flowing out of the ink storage tube is transferred to or penetrates into a recording medium such as paper due to the rotation of the ball, thereby performing writing. If the ball and the ball supporting portion that supports the ball are worn, the ball will not rotate smoothly, and the writing characteristics will be greatly reduced, eventually making it impossible to write. Therefore, it is important to reduce the wear of the balls and ball bearings. [0003] In order to reduce the wear of balls, methods such as using balls made of ceramics or coating the surface of metal balls w...
