TH14869C3 - The pressure regulator for writing tools and writing tools has the same thing. - Google Patents

Abstract

1 page of the number 1 page summary of the invention Pressure control devices for writing tools have components that can Transformable A slight change in air pressure in the pen tube of a writing instrument. Can be regulated by deformation of the deformable assembly. Transformation The large air pressure in the pen tube can also be regulated by the movement of the device. To regulate the pressure, so the pen tube of the writing instrument can avoid The imbalance of the inner air pressure arising from the high temperature or the low air pressure outside. Before writing tools will be shipped from the manufacturer. Assembly parts that can be transformed Will get the pressure boost in advance In such a way that a slight change in air pressure has formed When the pen cap covers the writing tool, it compensates for the exerted air pressure. In advance with the movable assembly, so the ink inside the inner cavity will not eject. When the pen cap is removed and the ink is not over-discharged or leaking during writing.
