Abstract: The technical problems of this invention are to overcome a limitation in the aspect of the shape of conventional synthetic resin double containers comprising an inner container and an outer container and to solve a problem of additional steps required to assemble the outer and inner containers. A principle means taken to solve these problems comprises a double container made by a direct blow molding process wherein a space is formed between the outer layer and the inner layer made of synthetic resins that are mutually non-adherent, thus allowing both layers to be left in a detached state due to a difference in mold shrinkage factors between the two layers during the direct blow molding step.

Abstract: The invention is aimed at preventing bottom crack from occurring in a peelably laminated plastic container and maintaining the container stably in good in-use condition. This can be achieved by increasing the anti-peeling strength of a pair of rib strips, with which the bottom rib is formed, in the bottom seal that has been obtained by pinching off the parison at the bottom and molding the parison into a blow molded, peelably laminated plastic container. The bottom seal 13 of a blow molded, peelably laminated container 1 is reinforced by a pair of rib strips 14 which are pressed to each other to form the bottom rib 15. A multiple number of cavities 16 are formed in the bottom rib 15 in such a way that the rib strip 14 on one side is pushed toward, and caved into, the rib strip on the other side at several points, and vice verse. An expanded portion 18 is formed in the ceiling of each cavity 16.

Abstract: A comb-carrying container is designed for applying substance by sequential action. The container has a hollow comb with a shaft, and a cap-like member formed at the lower end of the shaft, and a laminated container body consisting of an outer layer and an inner layer peelable therefrom and having an opened neck portion, to which the cap-like member is fitted, such that the liquid in the container may be discharged from the teeth of the comb through the shaft. In the present invention, the shaft 32 and the cap-like member 21 is separated each other, and a pump cylinder 11 is depending from the cap-like member 21 to the laminated container body 1, and a stem 41 is depending from the shaft 32 into the pump cylinder 11. A cylindrical piston 44 is attached at the lower end portion of the stem.
