Title (EN) IMPROVED MULTI-LAYER CONTAINER AND PREFORM
(FR) CONTENEUR ET PREFORME MULTICOUCHES AMELIORES
Abstract:
(EN) A multi-layer preform (90), includes: a) a plastic inner liner (10), comprised of a cylindrical walled body, which may or may not include a tapered annular shoulder portion, and a cylindrical walled neck portion extending upwardly from the body (88), and b) a molded outer layer (80). Prior to the outer layer being molded over the plastic inner liner, at least a portion of the liner is crystallized by a heat treatment process (84). The molded outer layer may include a means to receive a closure device (86). When the preform is at an acceptable temperature range for orientation, the multi-layer preform can be blow-molded to form a multi-layer container having improved properties.
(FR) Préforme (90) multicouches, comprenant: (a) un revêtement (10) intérieur en plastique formé d'un corps cylindrique entouré de parois, comprenant éventuellement une partie épaule annulaire conique, et une partie col (88) cylindrique à parois, prolongeant le corps vers le haut, et (b) une couche (80) extérieure moulée. Avant de mouler la couche extérieure sur le revêtement intérieur, on cristallise au moins une partie du revêtement par un procédé (84) de traitement thermique. La couche extérieure moulée peut comporter des moyens pour recevoir un dispositif (86) de fermeture. Lorsque la température de la préforme multicouche se situe dans une plage acceptable pour l'orientation, on peut mouler cette préforme par soufflage pour former un conteneur multicouches présentant des propriétés améliorées.
