Portable beverage container

Abstract

As shown in the exploded perspective view, this product consists of, from the left, a cap, an inner container, a cylindrical outer container, and a bottom cap. The outer male screw at the bottom of the inner container is screwed into the inner female screw of the bottom cap, and the outer flange at the top of the inner container is externally fitted onto the upper opening edge of the outer container, integrating the inner and outer containers. Thermal insulation is achieved by the insulating properties of the inner and outer container materials and the space between the inner and outer containers. A handle is attached to the top of the cap so that it can be raised or lowered for portability.
