发明名称 Safety ink pen
摘要 An ink pen is provided which is comprised of an outer rotating and sliding body which fits comfortably, overriding an inner ink containing cartridge. The outer body slides with respect to the inner cartridge when rotated with respect thereto. Rotation of the outer body with respect to the inner cartridge causes the cartridge to retract within the outer body, thus protecting the pocket of an individual upon placement of the pen in such a position when the pen is not in use. Inadvertent placement of the ink pen into a shirt pocket, for example, when the pen is in the writing position, is prevented by means of a projecting clip guard which catches on the outer portion of the pocket, thus preventing the pen from entry into the pocket when it is in its writing position.
