Description
Technical Field
The utility model relates to a writing instrument field especially relates to a straight liquid formula refill that beats.
Background
The development of ink writing instruments, from ball-point pens to gel-ink pens to today's direct-liquid water-based pens, uses inks from oil-based to gel-based to water-based, and has only one purpose: the writing is smoother and smoother.
The direct-liquid type water-based pen core needs to be in a fully-sealed state when not used, otherwise, ink can volatilize, and ink is easy to leak at the pen point under high temperature and high pressure. Most of direct-liquid type water pens in the current market are plug-in direct-liquid type water pens, and the direct-liquid type jumping pen core is high in research and development difficulty due to the self-sealing requirement.
Chinese patent publication No. CN101511604A, publication date 2009, 8/19, discloses a writing tool, which also includes a straight-liquid type jumping pen core, the internal ink guiding core is a split structure, the built-in spring acts on the ink guiding core, the ink guiding core props against the writing ball of the pen point, and the problem of ink volatilization or ink leakage is solved by the sealing formed between the writing ball and the inner edge of the pen point.
The disadvantage is that the sealing performance is not enough, and once the assembly is poor or the water diversion core is processed poorly, the spring acting force is lost, so that the sealing force of the writing ball is not enough. In other words, once the ink guide core is worn or machined or assembled a little bit, the ink guide core will be pressed against the side of the writing ball under the action of the spring, and the sealing force formed between the writing ball and the inner edge of the pen point will be inclined, resulting in the sealing failure and further the problems of ink volatilization or ink leakage.
