Abstract

A fluid reservoir includes a reservoir body, a heating structure, a piston, and an outlet port. The reservoir body includes a cross section, and a translation axis. The cross section is uniform along the translation axis. When fluid is housed in the reservoir, the heating structure is thermally coupled to the fluid. The heating structure energizes the fluid housed in the reservoir. The piston translates along the translation axis. An available volume of the reservoir to house the fluid is defined by a distance between the piston and an end of the reservoir body. When the piston is translated along the translation axis toward the end, a volume of the fluid that has been energized by the heating structure flows from the reservoir and through the outlet port. The volume of energized fluid is linearly proportional to a length of the translation of the piston.

Claims

1. A fluid reservoir comprising:

a reservoir body includes a piston-engagement end and a dispensing end, the piston-engagement end and the dispensing end defining opposite ends of the reservoir body, wherein fluid is housed in the reservoir body;

a valve assembly that has a chamber at least partially disposed within the reservoir body;

a heating structure thermally coupled to the fluid and configured to energize at least a portion of the fluid housed in the reservoir body, wherein the heating structure is disposed within the reservoir body, wherein the heating structure is external to the chamber of the valve assembly and at least partially surrounds the chamber of the valve assembly;

a piston configured to engage the piston-engagement end of the reservoir body, wherein a volume of the reservoir body available to house the fluid is defined by a distance between the piston and the dispensing end of the reservoir body; and

an outlet port in fluid communication with the reservoir body, such that when the piston is linearly translated toward the dispensing end of the reservoir body a volume of the fluid that has been energized by the heating structure flows from the reservoir body and through the outlet port.

2. The reservoir of claim 1, wherein the heating structure is disposed proximate to the dispensing end of the reservoir body.

3. The reservoir of claim 1, wherein the piston-engagement end of the reservoir body is an open end to receive the piston.

4. The reservoir of claim 1, wherein the reservoir body is a cylindrical body, wherein the dispensing end is a cylinder base.

5. The reservoir of claim 1, wherein the outlet port includes a valve configured such that the fluid housed in the reservoir body flows through the valve in response to the linear translation of the piston towards the dispensing end of the reservoir body.

6. The reservoir of claim 1, wherein the outlet port includes a valve retainer configured to mate with an aperture of a dispenser when the reservoir is received by a cavity within a dispenser.

7. The reservoir of claim 6, wherein the valve retainer includes a retainer perimeter that is configured such that when the fluid housed in the reservoir flows through the outlet port, the flowing fluid flows without contacting the retainer perimeter.

8. The reservoir of claim 1, wherein the outlet port is disposed proximate to the heating structure, such that the fluid that flows through the outlet port is proximate the heating structure prior to flowing through outlet port.

9. The reservoir of claim 1, wherein the piston includes a driven structure configured to mate with a driveshaft driven by an actuator.

10. A fluid reservoir that houses fluid, the reservoir comprising:

a reservoir body defines a longitudinal axis;

a valve assembly that has a chamber at least partially disposed within the reservoir body;

a heating structure thermally coupled to the fluid housed in the reservoir body and configured to energize at least a portion of the fluid housed within the reservoir body, wherein the heating structure is disposed within the reservoir body, wherein the heating structure is external to the chamber of the valve assembly and at least partially surrounds the chamber of the valve assembly;

a piston configured to translate along at least a portion of the longitudinal axis of the reservoir body;

a nozzle in fluid communication with the reservoir body, the nozzle configured to output the fluid housed within the reservoir body based on linear translation of the piston toward the nozzle; and

a first valve that resists the output of the fluid through the nozzle unless a dispensing force is applied to the reservoir body, wherein the dispensing force increases an internal pressure of the fluid to overcome a resistance of the first valve.

11. The reservoir of claim 10, further comprising a bottom cap that includes an aperture to enable a driveshaft to apply the dispensing force to the piston, wherein when the dispensing force is applied to the piston, the piston is translated along the longitudinal axis and the resistance of the first valve is overcome to output a portion of the fluid from the nozzle.

12. The reservoir of claim 10, further comprising a nozzle assembly, wherein when the dispensing force is applied to the nozzle assembly, the nozzle assembly is translated relative to the reservoir body and the resistance of the first valve is overcome to output a portion of the fluid from the nozzle.

13. The reservoir of claim 10, further comprising an alignment member that enables a proper nozzle alignment when the reservoir body is received by a fluid dispenser.

14. The reservoir of claim 10, wherein the heating structure includes a conductive tubular body that is internal to at least a portion of the reservoir body, wherein the tubular body is hollow.

15. The reservoir of claim 10, wherein the heating structure is a stainless steel heating structure.

16. The reservoir of claim 10, wherein the reservoir is an airless pump reservoir.

17. The reservoir of claim 10, further comprising an over cap that is configured to prevent an output of fluid from the nozzle when the reservoir is not in use.

18. A fluid reservoir comprising:

a reservoir body that includes a piston-engagement end and a dispensing end, the piston-engagement end and the dispensing end defining opposite ends of the reservoir body, wherein fluid is housed in the reservoir body;

19. The reservoir of claim 18, wherein the piston-engagement end includes a bottom cap and the bottom cap includes a central aperture configured to receive a driveshaft of an actuator.

20. The reservoir of claim 18, wherein the heating structure is disposed proximate to the dispensing end of the reservoir body.

21. The reservoir of claim 18, wherein the heating structure includes a conductive tubular body that is internal to at least a portion of the reservoir body, wherein the tubular body is hollow.
