Title
(EN) CONTAINER HAVING COMPOUND FLEXIBLE PANELS
(FR) RÉCEPTACLE À PANNEAUX FLEXIBLES COMPOSÉS
Abstract
(EN)
A plastic container (10) that is adapted for adjustment to internal volumetric changes such as those that occur as a result of internal pressure and temperature changes during the hot-fill process includes a container body (12)defining an internal space (24). The container body has at least one flexible (26,28) panel defined therein, which includes an outer flexible panel portion (38)and an inner flexible panel portion (40). The outer flexible panel portion has a shape when a pressure equilibrium exists between the internal space and ambient external pressure, and is further constructed and arranged to assume a shape of increased concavity when a sufficient underpressure exists in the internal space. The inner flexible panel portion is constructed and arranged to flex relative to the outer flexible panel portion in order to accommodate internal pressure changes within the container body. The inner and outer flexible panel portions accordingly work in tandem to permit efficient vacuum uptake in a hot-fill type container. In addition, a boundary (42) between the outer and inner flexible panel portions is preferably entirely curved.
(FR)
Un réceptacle en plastique (10) qui est conçu pour s'adapter à des changements volumétriques internes tels que ceux qui surviennent suite à des changements de température et de pression interne au cours du processus de remplissage à chaud comprend un corps de réceptacle (12) délimitant un espace interne (24). Le corps de réceptacle comporte au moins un panneau flexible (26, 28) délimité dans celui-ci, qui comprend une partie panneau flexible extérieure (38) et une partie panneau flexible intérieure (40). La partie panneau flexible extérieure a une forme lorsqu'il y a un équilibre de pression entre l'espace interne et la pression externe ambiante, et est en outre construite et conçue pour prendre une forme à concavité augmentée lorsqu'il y a une sous-pression suffisante dans l'espace interne. La partie panneau flexible intérieure est construite et conçue pour fléchir par rapport à la partie panneau flexible extérieure afin de s'adapter à des changements de pression interne dans le corps de réceptacle. En conséquence, les parties panneau flexible intérieure et extérieure travaillent en tandem pour permettre une accumulation de vide efficace dans un réceptacle de type à remplissage à chaud. De plus, une limite (42) entre les parties panneau flexible extérieure et intérieure est de préférence totalement incurvée.
