Portable fluid warming device

A portable heating system that is operative to heat fluid within a fluid reservoir, wherein the fluid reservoir includes a first reservoir portion and a second reservoir portion, the first reservoir portion has exterior surfaces, at least a portion of the fluid is within the first reservoir portion, and the second portion of the fluid reservoir includes a dispensing aperture, the system comprising:

• a housing;
• a receptacle within the housing that is configured and arranged to receive the first reservoir portion;
• a heating element housed in the housing, wherein the heating element extends along and surrounds at least a portion of the receptacle and is disposed external to the exterior surfaces of the first reservoir portion received by the receptacle such that when the first reservoir portion is received by the receptacle, the heating element is operative to provide thermal energy to the portion of the fluid within the first reservoir portion;
• and
• a power source that provides energy to the heating element, the power source being disposed in the housing below the heating element.

An apparatus that is operative to heat a fluid contained within a fluid reservoir having exterior surfaces, the apparatus comprising:

• a cylindrical housing that includes an upper end, a lower end in opposition to the upper end, an outer surface extending from an outer portion of the upper end to an outer portion of the lower end, and a housing longitudinal axis extending intermediate a center of the upper end and a center of the lower end;
• a cavity that extends into the housing and is configured and arranged to receive the fluid reservoir through a cavity opening positioned on the upper end of the housing, wherein the cavity includes a cavity longitudinal axis that is coaxial or parallel with at least a portion of the housing longitudinal axis;
• a heater that is housed within the housing, wherein the heater is configured and arranged to, when the fluid reservoir is received by the cavity, be disposed external to the exterior surfaces of the fluid reservoir and heat at least a portion of the fluid contained within the fluid reservoir and
• a power source that provides energy to the heater, the power source being disposed below the heater.

A portable device that is configured and arranged to heat a fluid contained within a portable fluid reservoir having exterior surfaces, the portable device comprising:

• a housing that includes a first longitudinal end, a second longitudinal end, and one or more outer lateral surfaces of the device 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 longitudinally intermediate the first and the second longitudinal ends;
• a heating element positioned longitudinally intermediate the cavity terminal and the second longitudinal end, wherein the heating element is operative to provide thermal energy to at least a portion of the fluid contained within the fluid reservoir when the fluid reservoir is received by the cavity with the heating element being disposed external to the exterior surfaces of the fluid reservoir;
• and
• a power source that provides energy to the heating element, the power source being disposed intermediate the cavity terminal and the second longitudinal end.
