ABSTRACT:
A retractable marking pen having a tip guard to protect the writing tip (nib) from contact with external material when the ink cartridge to which the tip is connected is retracted into the pen casing. The tip guard is composed of a pair of guard flaps which open allowing the writing tip to pass therethrough when the pen is placed in writing mode and close over the tip when the pen is in retracted mode. The guard flaps are a pair of continuous panels which extend from the inside wall of the pen casing and are integrally molded with the casing. Each guard flap has a rear section which is essentially parallel to the pen casing wall surface and a forward section which slopes towards the axis of symmetry of the pen casing at the writing end of the pen. A major bend line in the surface of each flap separates the forward section from the rear section of the flap and forms an abutment wall. As the cartridge is pushed forward the pressure exerted by the cartridge against the abutment wall causes the guard flaps to open. Upon retraction of the ink cartridge the guard flaps automatically reclose to protect the tip.
