    摘要: Concerning a container biaxially stretched and blow molded from a laminated preform obtained by an injection molding process utilizing a multi-nozzle section, it is a technical problem of this invention to create a delaminable function that is comparable to that of the delaminable bottles made by a direct blow molding process. A main means of this invention to solve this technical problem is a biaxially stretched, blow molded container obtained by molding a laminated preform in a shape of a test tube, the preform being molded by an injection molding process using a multi-nozzle section, and the container being a bottle having a neck, a body, and a bottom, and comprising an outer layer that forms an outer shell and an inner layer that forms an inner bag to be laminated in a peelable manner with an inner surface of this outer layer, wherein the inner layer is formed to have so thin a wall that the inner bag can be deflated under a pressure drop inside the inner bag caused by a decrease in volume of a content fluid; the outer layer and the inner layer are of a laminar structure in which the lamination extends over an entire height range from a predetermined height position of the neck to a lower end face of a gate mark, which remains to exist at a center of a bottom plate of the bottom; and the outer layer and the inner layer are peeled from each other, starting from an interface of lamination between the outer layer and the inner layer, and this interface is exposed outside at the lower end face of the gate mark and can be used as an air intake vent that enables outside air to be taken into the space between the outer layer and the inner layer
