Abstract

In various embodiments, a fluid delivery pod includes a first surface, a second surface that opposes the first surface, a reservoir body, an outlet port, a heating structure, and a valve assembly. The reservoir body is between the first and the second surfaces. The reservoir body is configured to house a fluid. The outlet port is positioned on a surface of the pod. The surface is between the first and the second surfaces. The heating structure is thermally coupled to the fluid housed within the reservoir body. The heating structure wirelessly receives energy from an energy source that is external to the fluid delivery pod. The wirelessly received energy heats the fluid housed within the reservoir body. In response to an application of compression forces on the first and the second surfaces, the valve assembly dispenses the heated fluid through the outlet port and out of the fluid delivery pod.

Claims

a first surface;

a second surface that opposes the first surface;

a reservoir body intermediate the first and the second surfaces, wherein the reservoir body is configured to house a fluid;

an outlet port in fluid communication with the reservoir;

a heating structure within the reservoir body and being electrically conductive to wirelessly receive inductive energy from an energy source that is external to the fluid reservoir to heat at least a portion of the fluid within the reservoir body; and

a valve assembly that is operative to, in response to an application of compression forces on the opposing first and the second surfaces, dispense at least a portion of the heated fluid through the outlet port.

2. The pod of claim 1, wherein a physical dimension of the heating structure is based on a fluid type of the fluid housed within the reservoir body.

4. The pod of claim 1, wherein the valve assembly includes a lower chamber and the heating structure is positioned around at least a portion of the lower chamber of the valve assembly.

5. The pod of claim 4, wherein the lower chamber of the valve assembly and the heating structure are coaxial along an axis that extends between the first and the second surfaces.

6. The pod of claim 1, wherein the heating structure is a conductive tube that includes a length, an inner radius, and an outer radius.

7. The pod of claim 6, wherein the length of the heating structure is between 13 and 17 millimeters.

8. The pod of claim 6, wherein the length of the heating structure is between 3 and 7 millimeters.

9. The pod of claim 1, wherein a lower chamber of the valve assembly slidably receives the heating structure.

a nozzle that communicates with an interior volume of the reservoir body and is configured and arranged to output the fluid housed within the reservoir;

a valve assembly that includes a lower chamber and a first valve that resists the output of the fluid through the nozzle unless a dispensing force is applied to the reservoir, wherein the dispensing force increases an internal pressure of the fluid to overcome a resistance of the first valve; and

a heating structure arranged around an outer surface of the lower chamber of the valve assembly, wherein when fluid is housed in the volume of the reservoir body, the heating structure is thermally coupled to the fluid and configured and arranged to heat at least a portion of the fluid housed within the body.
