ABSTRACT:
A push-pull dispensing closure for a container includes a child-resistant sleeve which is slidably retained between the closure dispensing cap and the closure base member. In its NORMAL position, the sleeve obstructs opening access to the cap. When the sleeve is pushed toward the base member to a READY position, the cap can be gripped for opening movement. The sleeve is molded with a resiliently deformable plastic into which a return force is introduced as the sleeve is pushed toward ists READY position.
