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.
Claims6
An improved corrector for dispensing correction liquid on writing errors, said improved corrector comprising:
- a main body having a tip liquid outlet through which a correction liquid may be dispensed;
- a rotary body provided within said tip liquid outlet, said rotary body being sized and positioned within said tip liquid outlet so as to prevent a correction liquid from being dispensed from said tip liquid outlet when said rotary body is stationary within said tip liquid outlet, said rotary body also being sized and positioned within said tip liquid outlet so as to allow a correction liquid to be dispensed from said tip liquid outlet when said rotary body is rotated within said tip liquid outlet;
- and
- biasing means for biasing said rotary body toward said tip liquid outlet, said biasing means comprising:
- an elongated biasing lever axially movable within said main body, said lever having a first end abutting said rotary body, said lever having a second end disposed within said main body inward from said liquid tip outlet;
- and
- a compressed spring member, said spring member firmly engaged with said second end of said lever so as to bias said rotary body toward said tip liquid outlet;
- the improvement comprising said second end of said lever having an integral lateral extension which firmly engages with said spring member so as to accurately specify an exact engaging position of said spring member relative to said lever and thereby apply a specific biasing force to said rotary body.
