REFILL PLUG RELEASE ASSEMBLY AND WRITING INSTRUMENT COMPRISING SAME

摘要

A writing instrument includes a barrel, a refill assembly, and a refill plug assembly that is quick to release from the barrel and quick to re-attach to the barrel when changing a refill assembly. The refill plug assembly is quickly secured to the barrel of the writing instrument and quickly released from the barrel of the writing instrument through a twisting and/or pushing action that may require less than one full turn to disengage from the barrel and to re-attach to the barrel, thus expediting replacement of the refill assembly.
