Writing tool

Abstract

The invention discloses a writing tool which comprises a nib for coating writing ink on a writing medium, a first ink storage cavity for supplying the writing ink to the nib and a connecting sleeve for connecting the nib. The writing tool is characterized in that: the writing tool also comprises at least one additional ink storage device which is wholly closed and filled with the writing ink, and at least one opening device for opening the writing ink in the at least one additional ink storage device to supply the writing ink to the nib; the additional ink storage device can move or rotate in a radial way corresponding to or along the opening device or the first ink storage cavity, which can not only increase the amount of the ink and prolong writing time, but also prevent and avoid the ink leakage effectively; the marking ink is not easy to reduce due to volatilization or air drying even being stored for a long time; the independent ink storage device that is wholly closed and filled with the marking ink 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 with the ink containing device, marking ink of which is used up, in the marking tool, thus prolonging the writing time of the marking tool, and effectively preventing and avoiding ink leakage at the same time; the phenomenon that the normal nib does not work before the marking tool leaves factory because the marking ink contained by the nib is easy to reduce due to volatilization or air drying or be blocked due to air drying is prevented and avoided effectively; 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 writing tool has the advantages of simple and reasonable structure, low cost, convenient processing, good anti-leakage performance and saving resources, which is suitable for mass production.

Description

technical field [0001] The present invention relates to a kind of writing instrument, especially such as color pen, felt tip pen, fiber tip pen, ballpoint pen, fountain pen, highlighter pen, paint pen, writing pen, marker pen, whiteboard pen, paintbrush, marking pen, used for repairing Nail markers for nails markers and other types of 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 stock of writing ink 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 filling exceeds the capacity that it can bear to store the writing ink, the pen is very easy to leak ink, so its leakage resistance is very poor, so the writing ink in the existing writing instruments The capacity of the liquid belongs to the structure of low capacity. 3. When the writing...

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 stock of writing ink is too small, and the frequency of changing new pens is very high

2. Due to the structure of the writing instrument itself, if the filling exceeds the capacity that it can bear to store the writing ink, the pen is very easy to leak ink, so its leakage resistance is very poor, so the writing ink in the existing writing instruments The liquid capacity 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

However, it was found that during the forward movement of the nib of this type of marking pen, too much liquid often flowed or penetrated into the nib and could not be sucked back in time, or sometimes the air was sucked back and the writing ink was rarely sucked back.

Furthermore, for the writing instrument with a nib with a ball, because it is closed, the liquid that penetrates or is pressed out can hardly be sucked back, so there is still a dripping phenomenon.
