Abstract
A correction fluid dispenser comprising a body member adapted to retain a correction fluid and a barrel disposed at one end thereof for delivery of the fluid to a surface. The barrel terminates in an orifice formed by a circular rim with a spherical ball of greater diameter disposed at the orifice. The ball is supported by a socket member, the ball and socket means being spring biased toward the orifice. A stop means is provided to prevent the ball from extending entirely within the rim of the orifice.
