A water bottle is provided to reduce manufacturing cost and increase warm-keeping effect while lowering its weight by improving an assembly structure with an inner container. A water bottle comprises a cylindrical inner container(10), made of stainless, with its top open in order to store contents inside; an outer container(20) where a heat insulator(21) is filled in gap with the inner container; a top coupling means(60) coupling the top of inner container and the top of outer container. The top coupling means in which outer container is molded with plastic resin and is combined to each other by fitting a connection frame(61) bent in section type, in which an outer wall(62) and the inner wall(63) is connected, into the top of the inner container and outer container with . The end part of the connection frame and the inner container is welded. |
