Marking instrument

Abstract

The invention relates to a marking tool which comprises a marking nib, an ink containing device and a housing. The invention is characterized in that the marking tool also comprises a dredging device and an additive ink storage device. The dredging device is used for dredging the marking ink in the additive ink storage device to be communicated with the marking nib, so as to provide the marking ink for the marking nib. The invention also comprises a safety device which is arranged in the additive ink storage device, thus effectively preventing and avoiding an ink leakage phenomenon; an air-dry reducing phenomenon can not occur even if the ink is placed for a long time; the marking ink can be conveniently supplied or complemented to the ink containing device, so as to realize the effect of being capable of writing or continuously writing; the marking tool can effectively prevent and avoid a phenomenon of incapable writing caused by that the marking nib is air-dried or plugged and can effectively prevent and avoid marking ink leakage phenomenon caused by easily pressing or pulling out the additive ink storage device by accident or when children play; the marking tool has the advantages of simple and reasonable structure as well as low cost, which is safe to use, prolongs the writing time and is suitable for mass production.

Description

markup tool technical field The present invention relates to a marking implement such as pastels, felt-tip pens, fiber-tip pens, ballpoint pens, fountain pens, paint pens, highlighters, markers, whiteboard markers, paint brushes, nail markers and markers for manicure and other types of recording tools. Background technique The ink-containing device, the main component of the existing marking tools on the market, is characterized by gaps and strong adsorption capacity. For example, the ink-containing device can be made of fiber material or felt material or similar or sponge or silk. Adsorb and store the marking ink 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 defects in the following aspects: 1. In the ink-containing device of the marking tool The amount of ink absorbed is too small, and the frequency of replacing new pens is high. 2. Due to the structure of ...

The ink-containing device, the main component of the existing marking tools on the market, is characterized by gaps and strong adsorption capacity. For example, the ink-containing device can be made of fiber material or felt material or similar or sponge or silk. Adsorb and store the marking ink 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 defects: 1. In the ink-containing device of the marking tool The amount of ink absorbed 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 to the ink-containing device exceeds the capacity it can withstand, the pen is very easy to leak ink, so its leak resistance is very poor, so the existing marking tools The capacity of the medium marking 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 tip of the marking pen will be easily dried or blocked, causing the ink-containing device in the marking tool to be filled with marking ink, but the tip of the marking pen cannot write

6. Especially a popular one-time use marking tool, often because the marking ink in the ink-containing device is used up quickly and the whole marking tool is still very new, it has to be discarded, so the utilization of the whole marking tool The rate is very low, resulting in a great waste of resources
