2129640 9315963 PCTABS00024 A plastic dispensing closure including a closure body (102), a lid, a resilient ''living'' hinge (106) joining the lid to the closure body, and camming members (118, 114) defined between the lid and the closure body to temporarily deform the hinge, within its elastic limits, as the lid is moved between its opened and closed position. One end of the hinge (106) is secured to a flexible holder (120) situated at the rear of the closure. Such holder (120) functions as a cantilever beam and serves as a spring to minimize the stress forces imposed upon the ''living'' hinge. The closure body, lid, and hinge may be integrally molded, and the holder (120) may be situated upon the closure body (Fig. 13), or upon the lid (Fig. 15) as design considerations dictate.
Fermeture de distribution en plastique comprenant un corps de fermeture (102), un couvercle, une charnière vive élastique (106) réunissant ledit couvercle et ledit corps de fermeture, ainsi que des éléments de came (118, 114) définis entre le couvercle et le corps de fermeture, de façon à déformer temporairement la charnière à l'intérieur de ses limites d'élasticité, lorsqu'on fait passer le couvercle de sa position ouverte à sa position fermée et inversement. Une extrémité de la charnière (106) est fixée à un support souple (120) situé à l'arrière de la fermeture. Ledit support (120) fait office de tige en porte-à-faux et sert de ressort, afin de réduire les efforts de contrainte s'exerçant sur la charnière vive. L'élément de fermeture, le couvercle et la charnière peuvent être moulés, de façon solidaire, et le support (120) peut être situé sur l'élément de fermeture ou sur le couvercle, en fonction de l'aspect extérieur souhaité de l'ensemble.
