ABSTRACT:
A dispenser for applying correction liquid to writing errors. The dispenser includes a valving rotary ball which controls the dispensing, with the rotary ball being normally biased against a spring member via an elongated biasing element, to shut off dispensing of the correction liquid. To insure integrity of shut-off and dispensing of correction liquid, the biasing member is a cylindrical member which has been integrally deformed at the end distant from the rotary ball to provide an outwardly extending stepped portion which firmly engages with the biasing spring.
