A modular writing instrument cap system is disclosed, in which each individual cap comprises an elongated tubular portion having an open end and a closed end. Near the closed end the cap is internally provided with a seal member adapted to seal with a writing instrument holding quick-drying ink. Near the open end, the tubular portion is internally provided with a catch for removably securing the cap on a writing instrument. Externally on the closed end, the cap is provided with a transversely-oriented open ended tubular barrel. The barrel is configured to receive an internally threaded sleeve, terminator rings and screws which thread towards one another through the rings into the opposite ends of the sleeve in order to hold the assembly together and secure a bail to it. The ends of the barrel and corresponding ends of the terminator rings are cooperatively notched to accommodate the legs of the bail. In order to create an assembly of two or more caps, the barrels of a respective number of caps are butted end to end, a tubular sleeve of appropriate length is slid into their barrels, and terminator rings, screws and a shared bail are secured together, uniting the cap assembly. The bail can be tightened down to act as a pocket clip, or up to act as a hanger.

A modular writing instrument cap system, comprising: at least one cap including a tubular sidewall having one open end and an opposite end closed by a transversely-oriented tubular barrel which includes a transversely-oriented bore that is open at both ends; means on said cap sidewall constructed and arranged for removably securing the cap on a writing instrument in telescopically enclosing relation to a working end of such writing instrument; said barrel being coaxially abuttable end-to-end with corresponding barrels of like caps to provide a series of adjoining caps, effectively having a shared transversely-oriented bore, and an exposed barrel end at each end of such series; a generally U-shaped bail, including a cross-arm and two generally parallel legs, each leg having a free end portion which is bent back generally at approximately a right angle and includes intermediate its extent an at least generally semi-circular hump, so that each such free end portion is generally omega-shaped; each end of each said barrel having means defining a correspondingly omega-shaped groove formed therein so as to open axially outwardly thereof; a pair of terminator rings each having a corresponding omega-shaped groove formed therein so as to open axially inwardly therefrom; each bail free end portion being received in a passageway defined by confrontation of a respective said omega-shaped groove at a respective exposed barrel end and a respective said omega-shaped groove in a respective said terminator ring; at least one internally threaded sleeve received in said transversely-oriented bore so as to have one end disposed adjacent a said omega-shaped groove of one said exposed barrel end and another end disposed adjacent a said omega-shaped groove of an opposite said exposed barrel end; and a respective screw bearing from axially outwardly against each terminator ring and having a shank thereof threaded into said at least one sleeve for securing said bail in relation to said at least one cap.
