Abstract

A pressure regulating device for a writing tool has a deformable member. Minor air pressure variations in a pen tube of the writing tool can be regulated by deformation of the deformable member. Major air pressure variations in the pen tube can also be regulated by movement of the pressure regulating device. Thus, the pen tube of the writing tool can avoid internal air pressure imbalance caused by external high temperature or low air pressure. Before the writing tool is shipped from a manufacturer, the deformable member is pressurized in advance, such that the minor air pressure variation formed when a pen cap caps the writing tool offsets the air pressure pre-applied to the deformable member. Accordingly, ink inside an internal chamber does not spout out upon removal of the pen cap and the ink will not be overly dispensed or leak during writing.
