Abstract:
1. A writing instrument configurable between a retracted configuration and an extended configuration, the writing instrument comprising: a body defining an interior volume and an axis, the body having an aperture through which the interior volume can be accessed, the axis passing through the aperture; a nib assembly including a nib and a reservoir for retaining ink, the nib assembly located inside the body and reciprocally movable along the axis; a valve for closing the aperture; a sleeve; whereby, when the nib assembly is in the retracted configuration, the sleeve surrounds the nib and the valve is closed; and whereby, at some point before the valve begins to open, the sleeve is at least partially disposed within the valve, and as the nib assembly is moved to the extended configuration, the sleeve initially opens the valve and the nib traverses the aperture.
