Abstract:
1. A tip assembly for a marking instrument having a body defining a fluid reservoir, the tip assembly comprising: a first rigid nib comprising a first angled marking surface, the first angled marking surface defining an acute angle relative to a centerline of the first rigid nib, the first rigid nib being coupled to the body and having a fluid path formed longitudinally therethrough; a moveable valve positioned within the fluid path, the moveable valve including a valve actuator; and a second rigid nib comprising a second angled marking surface, the second angled marking surface defining an acute angle relative to a centerline of the second rigid nib, the second rigid nib being disposed adjacent the first rigid nib and having a nib passage formed longitudinally therethrough, wherein the nib passage is sized to accept the first rigid nib and wherein the second rigid nib is placeable in a first extended position and a second retracted position; the second angled marking surface defining a second spreader surface positioned distal to the body, the second spreader surface cooperating with a first spreader surface defined by the first angled marking surface when the second rigid nib is in the first extended position to communicate fluid from the first rigid nib to the second spreader surface.
