Title: Solar heated canteen

Abstract

This patent describes an apparatus for confining a supply of water and enabling the water to be heated by solar radiation. The apparatus comprises: (a) a water-confining vessel having a panel of spherically rounded contour convexly directed outwardly from the vessel and centered upon an axis perpendicular to the vessel, an opposed lower panel, a boundary of circular configuration joining the upper and lower panels, and a sealable spout communicating with the interior of the vessel, (b) a jacket of self-supporting thermally insulative material, and comprised of (1) a bottom wall of circular perimeter adapted to lie in abutment with the lower panel, (2) a sidewall rising upwardly from the perimeter of the bottom wall as a continuous extension thereof and having an exterior surface extending between upper and lower extremities and an interior surface, (3) a channel which permits close-fitting passage of the spout, (c) a circular lens window of larger diameter than the vessel affixed at its perimeter to the upper extremity of the sidewall and coacting with the jacket to define an air chamber above the vessel. The lens is perpendicularly centered upon the axis of the upper panel and has a focal point coinciding with themore » center of curvature of the upper panel at a site on the axis below the bottom wall of the jacket, whereby light rays passing through the lens converge to the area of the upper panel while passing through the air chamber, and impinge perpendicularly upon the upper panel and heat the vessel, and (d) a carrying strap forming a substantially closed loop, a part of which embraces the exterior surface of the sidewall.« less
