Abstract
A nib for dispensing fluid comprising an elastomeric valve including a relatively rigid internal resistor. The nib is suitable for dispensing highly viscous fluids, such as paint, and for dispensing fluid containing particulate matter, such as glitter paint. Preferably, the nib includes a first sealing lip and a second sealing lip which meet to form a dispensing slit. Preferably, the nib has an exterior surface including first and second opposing faces, wherein each face includes an external resistor. The nib may also include one or more protrusions on the bottom of the nib. A instrument for dispensing fluid is also disclosed.
