Marker with penetrater

Abstract

The invention is concerned with a marking tool with open equipment. It relates to core containing liquid for adsorbing and storing marking ink (writing ink), marking pen point for spread the ink on the marking (writing) medium, shell for pretending the core and fastness cover for fixing the marking pen point. There is at least one ink-stored implement with marking ink outside or inside of the said tool, and there is the open equipment on the top of core containing liquid to open and lead the ink-stored implement and afford marking ink for pen point. The tool can be reused by filled with marking ink to keep record or write. At the same time, it avoids and prevents the leak of ink with easy structure, low cost, safety using and fit for produced in large.

Description

technical field [0001] The present invention relates to marking implements such as crayons, felt tip pens, fiber pens, ball point pens, fountain pens, highlighters, paint pens and other types of marking implements, especially marking implements with liquid cores. Background technique [0002] The liquid-containing core of the main part of the existing marking tool with a liquid-containing core has gaps and has the characteristics of strong adsorption capacity, and the marking ink is absorbed and stored in the liquid-containing core. For example: the liquid-containing core can be used Fiber materials or felt materials or similar materials with capillary attraction, but the amount of ink absorbed by it should not be too much, too much will cause liquid leakage of the marking tool, so this structure can only be of low capacity structure, the use time is very short; there is also a second ink storage chamber with a liquid outlet and a switch on the top of the liquid core.

[0002] The liquid-containing core of the main part of the existing marking tool with a liquid-containing core has gaps and has the characteristics of strong adsorption capacity, and the marking ink is absorbed and stored in the liquid-containing core. For example: the liquid-containing core can be used Fiber materials or felt materials or similar materials with capillary attraction, but the amount of ink absorbed by it should not be too much, too much will cause liquid leakage of the marking tool, so this structure can only be of low capacity structure, the use time is very short; there is also a second ink storage chamber with a liquid outlet and a switch on the top of the liquid core. When the marking ink in the liquid core is used up, it can be used by opening the switch. The second ink storage chamber supplies marking ink from the liquid outlet to the liquid-containing core, but this structure still has the following defects: ① When the marking tool is stored for a long time, due to the liquid outlet, the second The marking ink in the ink storage chamber will be naturally reduced or air-dried; ②When the marking tool is inadvertently turned upside down or horizontally supplemented with marking ink, the marking ink will flow sideways to the outside of the marking tool, causing damage to hands and clothing, etc. The risk of contamination; ③When the temperature and / or atmospheric pressure change, even if the sealing ring is used to seal, if the sealing ring is not tightly closed or the sealing time is slightly longer and loses elasticity, the expanding air will transfer the marking ink It is easy to squeeze out from the liquid outlet and easily cause liquid leakage; if the tightness of the sealing ring is improved, when the ink needs to be marked and needs to be rotated, the seal is too tight and the rotation is too tight, or the rotation is too hard Make the sealing ring easily deformed or cracked, resulting in leakage of the second ink reservoir or marking tool

④ When the marking ink in the liquid core or the second ink storage chamber is used up, it is difficult or impossible to replace the additional ink storage chamber, so that the marking tool is discarded when it is still new, resulting in a great waste of resources
