Abstract
A closure cap for a writing instrument such as a ink pen and the like has an outer generally cylindrical cap housing within which is a sealing sleeve having a closed end to close one end of the cap housing. A slide sleeve of a hard rigid material is retained against axial movement within the sealing sleeve. A closure member of a soft resilient durable material is axially slideable within the slide sleeve and is acted upon by spring means which may include a helical spring or axially extending resilient strips.
