A DIRECT BLOW MOLDING PROCESS FOR FORMING A DOUBLE CONTAINER OF SYNTHETIC RESIN |
摘要 |
<p>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.</p> |
