Writing instrument

Abstract

The invention relates to a writing tool which comprises a nib, an ink storage cavity, a dredging device and an additive ink storage device. The dredging device is used for dredging the writing ink in the additive ink storage device to be communicated with the nib, so as to provide the writing ink for the nib. The invention is characterized in that the writing tool also comprises a socket joint piece which is connected with the ink storage cavity; at least part of the additive ink storage device is arranged in the socket joint piece; the writing tool also comprises a safety device which is arranged on the additive ink storage device and can be connected with the socket joint piece; air-dry reducing phenomenon can not occur even if the ink is placed for a long time, thus prolonging the writing time; simultaneously, the additive ink storage device is led to be stably locked with the socket joint piece together; the additive ink storage device is hard to be pushed even if by accident or when children play, thus effectively preventing and avoiding ink leakage phenomenon. The writing tool has the advantage of simple and reasonable structure, which is safe to use and is suitable for mass production.

Description

technical field [0001] The present invention relates to a writing implement, such as pastels, felt-tipped pens, fiber-tipped pens, ballpoint pens, writing pens, fountain pens, paint pens, highlighters, markers, whiteboard markers, paint brushes, nail markers for manicure and other types of writing instruments such as markers, especially ink reservoirs that are replaceable on writing instruments. Background technique [0002] Although the writing implements 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 little, and the frequency of changing 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....

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
