Ink store device for marking instrument and marking instrument

Abstract

The invention relates to an ink storing device for a marking tool and the marking tool. The ink storing device comprises a canister body, and is characterized in that one end of the canister body is provided with a cover part, the other end of the canister body is provided with a bottom to form a fully closed ink storing device, the ink storing device is filled with marking ink liquid, and an ink liquid dropping leaking phenomenon is effectively prevented and avoided to appear; an ink liquid leaking phenomenon does not appear even if temperature and / or high atmospheric pressure change / changes; writing time is effectively prolonged; an air-dry reducing phenomenon is difficult to appear even if long time storage exists; an unable writing phenomenon which results form a pen point dried by air or stopped is effectively prevented and avoided; the marking tool with the ink containing device can be conveniently provided or supplemented with the marking ink liquid, or the ink storing device in which marking ink liquid is used up can be changed for many times, and the ink storing device is arranged in the marking tool with the ink containing device, and the writing or continuous writing effect is achieved. The ink storing device for a marking tool and the marking tool have simple and reasonable structures, low cost, good leaking resistance performance and safe use, prolong writing time, save resources, and are suitable for mass production.

Description

technical field [0001] The present invention relates to ink reservoirs for mounting in marking implements with absorbent ink-containing devices, such as crayons, felt-tipped pens, fiber-tipped pens, markers, paint pens, highlighters, markers, whiteboard markers , paint brushes, pens with fiber cores, pens with silk cores, pens with felt cores, nail markers and markers for manicure and other recording tools, especially those that can be replaced with ink-containing devices with adsorption capacity Ink reservoirs for marking tools and their marking tools. Background technique [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 or silk etc., absorb and store the marking ink in the ink-containing device to provide the marking ...

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 or silk etc., absorb and store the marking ink in the ink-containing device to provide the marking ink to the nib. Although the form is complex and changeable, and the variety is complete, there are the following defects: 1. The amount of ink absorbed in the ink-containing device 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. If the sealing of the shell is not good, or if it is accidentally bumped or squeezed and cracked, it is easy to cause the shell to leak ink.

6. Before the marking tool is used in the factory, if it is stored for a long time, the nib will be easily dried or blocked, causing the ink-containing device in the marking tool to be filled with marking ink, but the nib cannot write

7. 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 has to be discarded when it is still very new, so the utilization of the whole marking tool The rate is very low, resulting in a great waste of resources

However, it was found that during the forward movement of the nib of this 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 while the marking ink was rarely sucked back, Therefore, there is still the phenomenon of dripping ink
