Marking tool

Abstract

The invention relates to a marking tool comprising a marking nib, a graphite-containing device, a shell, a recanalizing device and an additional ink storage device. The recanalizing device is used for recanalizing the marking ink in the additional ink storage device to be communicated with the nib to provide ink for the nib. The marking tool is characterized in that the tool also comprises a safety device which is arranged on the additional ink storage device and connected with the shell and the safety device leads the additional ink storage device to form the total-closed structure which is filled with marking ink, so as to effectively avoid the phenomenon of ink dripping, thus the air drying and reducing phenomenon is not easy to appear even if the marking tool is stored for a long time. The marking tool can conveniently supplement marking ink in the marking tool of the graphite-containing device, or the additional ink storage device that uses up the ink in the marking tool of the graphite-containing device can be replaced for a plurality of times, thus achieving the effect of being used for writing or continuously writing. The structure is simple and reasonable, the cost is low, the use is safe, therefore, the invention is suitable for batch production.

Description

Technical field [0001] The invention relates to a marking tool, such as color pens, felt tip pens, fiber tip pens, ballpoint pens, fountain pens, paint pens, highlighters, markers, whiteboard pens, paint brushes, nail markers and marker pens for manicure And other types of recording tools, especially the ink tank that can be replaced on the marking tool of the ink-containing device with adsorption capacity. Background technique [0002] The main components of the marking tools with ink-containing devices on the market. The ink-containing devices are characterized by gaps and strong adsorption capacity. For example, the ink-containing devices can be made of fiber materials or felt materials or the like or sponges. , The marking ink is absorbed and stored in the ink-containing device to provide marking ink to the marking pen tip. Although the form is complex and changeable, and the variety is complete, there are several common shortcomings: 1. The amount of ink stored is too large....

AI Technical Summary

Problems solved by technology

[0002] The main component of the marking tool with ink-containing device in the existing market is that the ink-containing device has a gap and has the characteristics of strong adsorption capacity. For example, the ink-containing device can be made of fiber material or felt material or similar or sponge, etc. , the marking ink is absorbed and stored in the ink-containing device to provide the marking ink to the marking nib. Although the form is complex and changeable, and the variety is complete, there are the following common shortcomings: 1. The amount of stored ink is too large. Less, the frequency of replacing new pens is 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. Before the marking tool is used in the factory, if it is stored for a long time, the marking pen tip will be easily dried and blocked, causing the marking tool to be filled with marking ink, but the marking pen tip cannot write

6. 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

[0003] With regard to the marking tool provided with an ink reservoir outside the ink-containing device, when the marking ink in the ink-containing device is used up or will be used up, push the ink reservoir, and use the opening device to open the marking ink in the ink reservoir to the Marker nibs are provided for extended writing time, however, the marking tool can easily drip ink when the reservoir is pushed inadvertently or while children are playing
