PROBLEM TO BE SOLVED: To provide a double-wall-structure liquid container such as a stainless bottle improving aesthetic appearance by making the shape of a mouth part in contact with a mouth soft, reducing mutual dimensional limits of inner/outer cylinders, and making the shape of a body shoulder part sharp.SOLUTION: The liquid container comprise: a container body consisting of an inner cylinder in which liquid is stored, and an outer cylinder storing the inner cylinder via a space; the mouth part formed at an upper end of the container body; and a plug body detachably provided on the mouth. The upper ends of the inner cylinder and the outer cylinders are integrally joined with each other via a mouth forming member that has a separate body from the inner cylinder and the outer cylinder. In the double-wall-structure liquid container such as a stainless bottle, this configuration can make the shape of the mouth in contact with the mouth soft, reduce the mutual dimensional limits of the inner/outer cylinders, and make the shape of the body shoulder part sharp, thus improving the aesthetic appearance. |
