A preform (32) and method used to make a container (10, 110) which has a blown wide-mouth finish (20, 120) and a multilayer wall structure. The injection molded preform (32) has a multi-layer container body forming portion (54), a mono-layer moil forming portion (52) and a blown finish forming portion (56) located between the container body forming portion (54) and the moil forming portion (52). The preform (32) is blown into an intermediate article (36) consisting of a blown finish wide-mouth multi-layer container (10, 110) and a mono-layer moil portion (38) which is severed from the intermediate article (36) and recycled. The multilayer wall structure can include at least one layer (22) of a gas barrier material, a cost-effective recycled material, or a material which strengthens and/or lightweights the container (10, 110).

Préforme (32) et procédé utilisés pour fabriquer un récipient (10, 110) présentant une finition d'ouverture moulée (20, 120) et une structure multicouche de paroi. La préforme (32) moulée par injection présente une partie (54) de façonnage d'un corps multicouche, une partie (52) de façonnage d'un collier monocouche et une partie (56) de finition soufflée située entre la partie (54) et la partie (52). On souffle la préforme (32) afin d'obtenir un article intermédiaire (36) consistant en un récipient (10, 110) multicouche possédant une ouverture de finition soufflée, et en une partie collier monocouche (38) qu'on sectionne afin de la séparer de l'article intermédiaire (36) et qu'on recycle. La structure multicouche de la paroi peut comprendre au moins une couche (22) de matériau imperméable au gaz, de matériau recyclé économique ou de matériau renforçant et/ou allégeant le récipient (10, 110).
