<p>PURPOSE:To obtain a container without liquid leakage by a method wherein a specified synthetic resin layer is provided at the inside of the end part of a waterproof and anticorrosive layer of the container which is fabricated in the manner that its waterproof and anticorrosive layer is faced inside thereof. CONSTITUTION:The end inside of a material 1 having a waterproof and anticorrosive layer of synthetic resin and the like (for example, polyethylene) is so applied with molten synthetic resin as projecting from its end. Then, said synthetic resin is cooled and molded to form a synthetic resin layer (a). The obtained material 1, when forming it, for example into a container 14, is sealed up with a synthetic resin layer a when joining the end parts 1a, 1b. Accordingly the liquid oozing out of the container 14 is more completely prevented.</p> |
