Abstract: PURPOSE: To provide a double structured container manufacturing method for improving adiabaticity by forming an air layer between an inner container and an outer container and bonding a joint part thereof by ultrasonic heating and improving coupling force by forming arc shaped coupling protrusions on an end part of coupling flange of the inner container, and a coupling structure of double structured container manufactured by the same. CONSTITUTION: The method for manufacturing a double structured container comprises an inner container manufacturing process of manufacturing an inner container(10) an upper part of which is opened, in which a space part(11) for keeping food is formed, and an upper end part of which is folded outward to form a coupling flange(12) after drawing a stainless steel sheet; an outer container manufacturing process of ejection molding synthetic resin into an outer container(20) which is formed to envelope the outer circumferential surface of the inner container, on an upper part of which handles(21) are projected orthogonally along the circumference of the container, and in which a coupling groove(22) is formed downward in a concave shape along the inner circumference of the handles; and a bonding process of coupling the coupling flange of the inner container to the coupling groove of the outer container in such a way that an air layer with a certain thickness between the inner and outer containers, wherein the inner and outer containers are bonded by heating a joint part of the inner and outer containers using ultrasonic waves in the bonding process.
Abstract translation: 目的：提供一种双重结构化的容器制造方法，通过在内容器和外容器之间形成空气层并通过超声波加热将其接合部分接合并通过在端部的一部分上形成弧形耦合突起来提高耦合力来提高绝热性 内部容器的联接凸缘，以及由其制造的双重结构化容器的联接结构。 构成：制造双重结构化容器的方法包括制造内部容器（10）的内部容器制造过程，内部容器（10）的上部被打开，其中形成有用于保持食物的空间部分（11），以及上部 其中一部分向外折叠以在拉制不锈钢板之后形成联接凸缘（12）; 将合成树脂喷射成外壳的外容器制造工序，该外容器形成为包封内容器的外周面，上壳体的上部沿着容器的圆周正交地投影 ，并且其中联接槽（22）沿着手柄的内圆周向下形成为凹形; 以及将内部容器的联接凸缘联接到外部容器的联接槽的接合工艺，使得在内部和外部容器之间具有一定厚度的空气层，其中内部和外部容器通过加热 在接合过程中使用超声波的内外容器的接合部分。
