Abstract
This invention is aimed at preventing containers effectively from performance deterioration, such as exposure of the recycled material at the neck and reduced strength of the pinch-off portion, as caused by a high ratio of recycled material used as the middle layer. There is provided a multi-layered blow-molded container molded from cylindrical multi-layered parison, wall of the container comprising at least an outer layer, an inner layer, and a middle layer, wherein the outer and inner layers are made of a same synthetic resin, while the middle layer is made of a recycled material consisting primarily of the synthetic resin used for the outer and inner layers. This container is characterized in that it has either middle-layer excluded zones or a thin middle-layer zone. These zones are provided at a predetermined range along the direction in which the parison is extruded.
