CA 2444677

A container (110) having an inverted active cage generally includes an enclosed base portion (120), a body portion (130) extending upwardly from the base portion, and a top portion (140) with a finish (150) extending upwardly from the body portion. The body portion further includes a central longitudinal axis (L), a periphery, a plurality of active surfaces (160), and a network of pillars (170). Unlike the prior art, each of the plurality of active surfaces is outwardly displaced with respect to the longitudinal axis, while each of the network of pillars is inwardly displaced with respect to the longitudinal axis. The plurality of active surfaces, together with the network of pillars, are spaced about the periphery of the container in order to accommodate vacuum-induced volumetric shrinkage of the container resulting from a hot-filling, capping and cooling thereof.

L'invention concerne un récipient (110) à surfaces actives inversées comprenant généralement une partie de base fermée (120), une partie de corps (130) se prolongeant vers le haut à partir de la partie de base, ainsi qu'une partie supérieure (140) munie d'une bague (150) et se prolongeant vers le haut à partir de la partie de corps. La partie de corps comprend également un axe longitudinal central (L), une périphérie, une pluralité de surfaces actives (160) et un réseau de piliers (170). Contrairement à la technique antérieure, chaque surface de cette pluralité de surfaces actives se déplace vers l'extérieur par rapport à l'axe longitudinal, chaque pilier du réseau de piliers se déplaçant vers l'intérieur par rapport à l'axe longitudinal. Ces surfaces actives et ces piliers sont espacés autour de la périphérie du récipient en vue de permettre un retrait volumique dudit récipient sous l'effet du vide consécutivement à un remplissage à chaud, un capsulage et un refroidissement.
