Abstract
An interchangeable, vacuum-sealed beverage bottle includes a body having a cap housing, a plug assembly disposed at the cap housing, a handle engaged to the cap housing, an inner flask in fluid communication with the plug assembly, and an outer flask sealed to the inner flask such that a sealed vacuum cavity is defined between an outer surface of the inner flask and an inner surface of the outer flask (single liquid-containing chamber is double-walled and a vacuum is created between the walls). An exterior cover is positioned about the inner flask and the outer flask, and an end cap mated to the exterior cover and the outer flask. Downward and upward axial displacement of a portion of the plug assembly permits and prohibits fluid to freely flow outwardly from the inner flask to an exterior of the plug assembly, respectively.
