    • The present invention relates to a method for manufacturing a laminated container and the laminated container using the same. The method comprises: a first injection step for injecting a resin into a mold through a first extruder, wherein the resin is for forming an inner layer and outer layer; a second injection step for injecting a resin between the inner layer and outer layer into the mold through a second extruder after the first injection step, wherein the resin is for forming an intermediate layer; a molding step for forming the outer shape of the container after the second injection step; and an inner layer shrinkage step for separating the inner layer from the intermediate layer and shrinking the inner layer by exhausting the inner air of the container in a state where the opening of the container is sealed after the molding step. Accordingly, a laminated container can be manufactured with no an adhesive layer between layers, so production costs may be reduced. Since an additional post-treatment process for forming breath holes is not needed and damage to the inner layer can be checked while breath holes are formed, productivity of the laminated container can be improved.
    • 用于制造层压容器的方法和使用该方法的层压容器技术领域本发明涉及用于制造层压容器的方法和使用该方法的层压容器。 该方法包括:第一注射步骤,用于通过第一挤出机将树脂注入模具中,其中所述树脂用于形成内层和外层; 第二注射步骤,用于在第一注射步骤之后通过第二挤压机将内层和外层之间的树脂注射到模具中,其中所述树脂用于形成中间层; 成型步骤,用于在第二注射步骤之后形成容器的外部形状; 以及内层收缩步骤,用于在模塑步骤之后在容器的开口被密封的状态下通过排出容器的内部空气而将内层从中间层分离并收缩内层。 因此,可以在层之间没有粘合剂层的情况下制造层压容器,因此可以降低生产成本。 由于不需要用于形成呼吸孔的附加后处理过程,并且可以在形成呼吸孔的同时检查对内层的损伤,因此可以提高层压容器的生产率。
