Claim of US Patent No. 10,433,372

1. A device to heat a fluid contained within a separate fluid reservoir, the device comprising:a housing that includes a first longitudinal end, a second longitudinal end, and one or more outer lateral surfaces extending from a laterally outer portion of the first longitudinal end to a laterally outer portion of the second longitudinal end;
a cavity within the housing that extends from a cavity port that is positioned on a laterally inner portion of the first longitudinal end to a cavity terminal that is positioned intermediate the first and the second longitudinal ends, wherein one or more inner lateral surfaces of the device are positioned adjacent the cavity and extend from the laterally inner portion of the first longitudinal end to a laterally outer portion of the cavity terminal;
a fluid reservoir received in the cavity, the fluid reservoir having one or more walls with interior surfaces and exterior surfaces, the fluid reservoir having a heating structure that is spaced apart from an entirety of the one or more walls, wherein the one or more inner lateral surfaces are positioned adjacent one or more portions of the exterior surfaces of the fluid reservoir; and
an energizing element that surrounds the cavity and that is disposed external to exterior surfaces of the fluid reservoir received in the cavity such that a portion of the cavity is positioned laterally intermediate a first energizing element portion and a second energizing element portion, wherein the energizing element is operative to provide energy to at least the intermediate portion of the cavity to transfer thermal energy to the fluid reservoir to control a temperature of a fluid in the fluid reservoir.
