2115645 9303972 PCTABS00020 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.

Cette invention concerne des améliorations relatives à des dispositifs de fermeture à charnière encliquetable destinés à des bouteilles en plastique moulé. Plus particulièrement, ces dispositifs de fermeture à charnière encliquetable et à paroi unique sont pourvus d'un système qui permet de les aligner avec la partie avant de la bouteille, et d'un évidement en forme de pouce relativement plus profond qui sert à faciliter l'ouverture du couvercle de fermeture à charnière encliquetable. Un système est également prévu pour empêcher la rotation en sens contraire du dispositif de fermeture dès lors qu'il est correctement aligné. D'autres caractéristiques sont également présentées, lesquelles concernent un bouchon qui empêche la bouteille de fuir et de perdre son contenu et un système qui empêche le dispositif de fermeture de pivoter de manière axiale.
