Marking tool

Abstract

The invention discloses a marking tool which comprises a marking nib for coating a marking ink on a surface and an ink storage cavity for supplying the marking ink to the marking nib. The marking tool is characterized in that: the marking tool also comprises an ink containing device with adsorption function, at least one additional ink storage device which is wholly closed and filled with the marking ink, and at least one opening device; at least part of the ink containing device is arranged in the ink storage cavity; the opening device is used for opening the marking ink of the additional ink storage device to supply the marking ink to the marking nib; the additional ink storage device can move or rotate in a radial way corresponding to or along the opening device or the ink storage cavity, which effectively prevents and avoids the phenomenon that the normal marking nib does not work before the marking tool leaves factory because the marking ink contained by the marking nib is easy to reduce due to volatilization or air drying or be blocked due to air drying; the phenomena that the marking ink is reduced due to natural volatilization or air drying or the marking ink leaks is prevented and avoided effectively; the marking ink is not easy to reduce due to volatilization or air drying even being stored for a long time; the storage amount of the ink is increased, the writing time is prolonged and the ink leakage is prevented effectively; the independent ink storage device is used for supplying or supplementing the marking ink to the ink containing device of the marking tool, or can replace the ink storage device, marking ink of which is used up, in the marking tool, thus prolonging the writing time, and effectively preventing and avoiding ink dripping and leakage. The marking tool has the advantages of simple and reasonable structure, low cost, convenient processing and good anti-leakage performance, which saves resource and is suitable for mass production.

Description

Technical field [0001] The invention relates to a marking tool, especially such as color pens, felt tip pens, fiber tip pens, ballpoint pens, fountain pens, highlight pens, paint pens, marker pens, whiteboard pens, writing pens, marking pens, brushes, used for repairing Nail markers and other types of recording tools for nails. Background technique [0002] Although the existing marking tools on the market have complex forms and a complete variety, they all have the following common shortcomings: 1. The amount of ink stored is too small and the frequency of replacing new pens is high. 2. Due to the structure of the marking tool itself, if the amount of marking ink added exceeds the capacity of the marking tool itself, the pen is very easy to leak ink, so its leak resistance performance is very poor, so the existing marking tools mark The ink capacity is a low-capacity structure. 3. When the temperature and / or atmospheric pressure change, the expanded or pressurized air will exert...

AI Technical Summary

Problems solved by technology

[0002] Although the marking tools on the existing market are complex in form and complete in variety, they all have the following common shortcomings: 1. The amount of ink stored is too small, and the frequency of replacing new pens is very high

2. Due to the structure of the marking tool itself, if the amount of marking ink exceeds the capacity of the marking tool itself, the pen is very easy to leak ink, so its leak resistance is very poor, so the existing marking tools The capacity of the ink is a low-capacity structure

3. When the temperature and / or atmospheric pressure changes, the expanded or pressurized air will generate pressure on the marking ink, which will cause the marking tool to leak ink

5. If the seal of the ink storage chamber is not good, or if it is accidentally bumped or squeezed and ruptures, it is easy to cause ink leakage in the ink storage chamber

6. Before the marking tool is used in the factory, if it is stored for a long time, the marking tip will be easily dried and blocked, causing the marking tool to be filled with marking ink, but the marking tip cannot write

7. Especially a popular one-time use marking tool often has to be discarded when the marking ink is used up quickly and the whole marking tool is still very new, so the utilization rate of the whole marking tool is very low. cause a lot of waste of resources

However, it was found that during the forward movement of the marker tip of this marker pen, too much liquid often flowed or penetrated into the marker tip and could not be sucked back in time, or sometimes the air was sucked back and the marking ink was hardly absorbed. Back, therefore, there is still the phenomenon of dripping ink
