ABSTRACT:
A blow-molded container includes an outer layer of a synthetic resin, which forms the outer shell of a finite shape; an inner layer of a flexible synthetic resin, which is peelably laminated with the outer layer and forms an inner bag; and a pair of adhered zones of a vertical strip type, which is formed axisymmetrically on the central axis of container to adhere and fix the outer layer and the inner layer over the entire height and is located so as to avoid the positions of air introduction ports that have been provided in the outer layer to introduce air into the void between the outer layer and the inner layer. A pair of adhered zones is disposed at positions opposite to each other and is separated by a parting line. The lower ends of both adhered zones are disposed at the partly or wholly end-to-end position facing each other on the bottom seal formed when the bottom portion is pressed flat with the pinch-off of a blow mold. Because of this end-to-end facing position of the lower ends, the bottom seal has a full mechanical strength. Thus, there is provided a container of the delaminated type capable of molding by means of an ordinary mold and having high manufacturing efficiency.
