Abstract
A retractable pen includes a cartridge partially received in a recess of a cap such that a first end of the cartridge is fixedly attached to the cap. An elongate barrel includes first and second open ends and a through channel fluidly interconnecting the first and second open ends. A portion of the barrel is snugly and threadedly received in the recess such that the cartridge is received in and extends through the through channel, and the barrel and the cap are rotatingly movable relative to each other via the threaded engagement between an extended position in which the second end of the cartridge extends through and out of the second open end of the barrel, and a retracted position in which the second end of the cartridge is disposed within the barrel.
