A liquid container (10) comprising a multi-layer container including a wall (32) made up of a main layer (40) and a separate, delaminatable inner layer (42), a container opening (34) at the top for filling and evaluation and a plurality of air vents (38) extending completely through the main layer and terminating at the inner layer, such that the inner layer delaminates when liquid is evacuated by suction. The inner layer is thicker at the top end of the container and the air vents have a larger size opening at the bottom of the container, both to prevent premature collapse of the top end of the inner layer. The inner layer is also at least partially predelaminated during (or right after) manufacturing to assist ease of delamination during use.
Réservoir de liquides multicouche (10) comprenant une paroi (32) faite d'une couche principale (40) et d'une sous-couche intérieure séparée délaminable (42), un orifice supérieur de remplissage/vidage (34) et plusieurs évents (38) traversant de part en part la couche principale de façon à permettre le décollement de la couche intérieure lorsque le liquide est évacué par succion. La couche intérieure est plus épaisse au sommet du réservoir et les évents sont plus larges à sa base; ces deux traits empêchant la rétraction précoce de l'extrémité supérieure de la couche intérieure. Ladite couche subit un prédélaminage partiel pendant la fabrication (ou immédiatement après) pour en faciliter le décollement lors de l'utilisation.
