Writing instrument

Abstract

The invention relates to a writing tool which comprises a pen tip, an ink storage cavity, a communication device and an additional ink storer, wherein, the communication device is used for communicating the writing ink in the additional ink storer and the pen tip so as to provide the writing ink for the pen tip. The invention is characterized in that the writing tool also consists of a sleeve joint part which is connected with the ink storage cavity, with part of the additional ink storer arranged inside the sleeve joint part, and a safety device which is arranged on the additional ink storer and can be connected with the sleeve joint part. Even if being stored for a long time, the writing tool is not air dried, thus the writing time is lengthened; meanwhile, since the additional ink storer is stably locked with the sleeve joint part, the additional ink storer is not easy to be pushed, regardless of carelessness and incaution caused by the playing children, thus the ink leakage and dropping can be prevented and avoided effectively. In addition, the writing tool is of simple and reasonable structure and safety application, and is applicable to mass production.

Description

Technical field [0001] The invention relates to a writing tool, such as color pens, felt tip pens, fiber tip pens, ballpoint pens, writing pens, fountain pens, paint pens, highlight pens, markers, whiteboard pens, paint brushes, nail markers for manicure And other types of recording tools, such as marker pens, especially the ink reservoir that can be replaced on the writing tool. Background technique [0002] The existing writing instruments on the market, although their forms are complex and changeable, and their varieties are complete, 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 writing tool itself, if the amount of writing ink filled exceeds the capacity of the writing tool itself, the pen is very easy to leak ink, so its leak resistance performance is very poor, so writing in existing writing tools The ink capacity is a low-capacity structure. 3.

Problems solved by technology

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

2. Due to the structure of the writing instrument itself, if the amount of writing ink added exceeds the capacity of the writing instrument itself, the pen is very easy to leak ink, so its leak resistance is very poor, so writing in existing writing instruments The capacity of the ink is a low-capacity structure

4. Especially a kind of disposable writing instrument of popular type, often because writing ink fluid is used up fast and whole writing instrument is still very new just has to be discarded, thereby the utilization rate of whole writing instrument is very low, cause a lot of waste of resources

[0003] With regard to writing implements having at least two ink reservoirs for supplying writing ink to the nib, generally the first ink reservoir supplies writing ink to the nib first, and when the writing ink in the first ink reservoir is used up , push the second ink reservoir, and use the opening device to open the writing ink in the second ink reservoir to continue to provide to the nib, thus prolonging the writing time and saving resources, but, when the second reservoir is unintentionally or children are playing Ink container, it is easy to cause ink dripping in writing instruments
