ABSTRACT:
A writing device cap comprises a cylindrical outer housing having a first open end, a second closed end and an axial channel. A plug is inserted in the outer housing second closed end. A moveable inner cone located within the cylindrical outer housing receives a tip of a writing device and seals it from the ambient atmosphere. A spring surrounds the inner cone and facilitates it movement. A plurality of radially disposed ridges are arranged along an inner circumference of the outer housing along the axial channel. Multiple sets of shoulders are disposed upon the ridges. A first set of shoulders provides a stop for a body trunk of the writing device and a means to locate the inner cone when the spring is in a relaxed state. A second set of shoulders locates a fixed end of the spring. A third set provides a means for locking the plug within the outer housing. A latch mechanism holds the writing device in the cap when the spring is in a compressed state. A plurality of air vents formed on the plug permit air to pass through the cap in case it accidentally swallowed and lodged in the throat of a person.
