Abstract
This invention is directed towards improvements in snap hinge dispensing closures for molded plastic bottles. In particular, snap hinge closures of single walled construction are provided with means for positively aligning with the front of the bottle, and a relatively deeper thumb recess for facilitating lifting of a snap hinge closure lid. Means are also disclosed to prevent reverse rotation of the closure once positive alignment is achieved. Other disclosed features include a plug to prevent leakage of the bottle contents and means for preventing axial pivoting of the closure.
