Abstract

A heat storage unit (2) includes a body having a passage (12) formed therein through which a flowable product passes. A heatable element (10) is incorporated within the body of the heat storage unit (2) in thermal communication with the passage (12). The heatable element (10) includes either a magnetically-compatible material or a microwave-compatible material that is heated by locating the heatable element in a field (F) generated by a charging device (6), for example.

Claims

1. A heat storage unit that heats a flowable product prior to dispensing, the heat storage unit comprising:

a body having a passage formed therein through which a flowable product passes; and

a heatable element incorporated within the body in thermal communication with the passage, the heatable element comprising either a magnetically-compatible material or a microwave-compatible material that is heatable by locating the heatable element in a field generated external to the heat storage unit,

wherein the heat storage unit does not include any components for generating a field to heat the heatable element.

2. The heat storage unit of claim 1, wherein the heatable element comprises a magnetically-compatible material that is heatable by locating the heatable element in a magnetic field.

3. The heat storage unit of claim 1, wherein the heatable element comprises a microwave-compatible material that is heatable by exposing the heatable element to microwave radiation.

4. The heat storage unit of claim 1, wherein the passage in the body comprises an inlet for receiving the flowable product into the body, an outlet for directing the discharge of the flowable product from the body, and a reservoir located between the inlet and the outlet, the reservoir being sized to accommodate at least one dose of the flowable product.

5. The heat storage unit of claim 1, further comprising an identification device applied to or incorporated within the body, the identification device storing information about the heat storage unit or about a flowable product used therewith.

6. The heat storage unit of claim 1, wherein the body is configured as a cartridge that is detachably securable to each of a plurality of different flowable product dispensers.

7. The heat storage unit of claim 1, wherein the body is configured as an overcap that is detachably securable to an aerosol container.

8. The heat storage unit of claim 1, wherein the heatable element comprises a porous, mesh-like material that is disposed within the passage.

9. The heat storage unit of claim 1, wherein the heat storage unit does not include a heat-retentive material.

10. The heat storage unit of claim 1, further comprising an insulating layer arranged within the body to limit the dissipation of heat from the heat storage unit to the ambient surroundings.

11. The heat storage unit of claim 1, wherein the body is configured as a porous pad having incorporated therein a burstable pouch containing the flowable product.

12. A system, comprising:

a heat storage unit, comprising (i) a body having a passage formed therein, and (ii) a heatable element incorporated within the body in thermal communication with the passage, the heatable element comprising either a magnetically-compatible material or a microwave-compatible material; and

a charging device to which the heat storage unit is detachably docked such that, when the heat storage unit is docked with the charging device and the charging device is activated, a field is generated that encompasses the heatable element of the heat storage unit, thereby raising the temperature of the heatable element.

13. The system of claim 12, wherein the charging device includes a detection device that detects when an object having a radio frequency identification tag with particular information stored therein is docked with the charging device, and the charging device only generates the field when an object having a radio frequency identification tag with the particular information stored therein is detected.

14. The system of claim 12, wherein the heatable element comprises a magnetically-compatible material, and the charging device includes an induction coil for generating a magnetic field.

15. The system of claim 12, wherein the heatable element of the heat storage device is a microwave-compatible material, and the charging device includes a microwave-generating device.

16. The system of claim 12, wherein the heat storage unit further comprises an identification device that stores information about the heat storage unit or about a flowable product used therewith, and wherein the charging device includes a detection device that detects the information stored by the identification device.

17. The heat storage unit of claim 12, wherein the passage in the body of the heat storage unit comprises an inlet for receiving a flowable product into the body, an outlet for directing the discharge of the flowable product from the body, and a reservoir located between the inlet and the outlet, the reservoir being sized to accommodate at least one dose of the flowable product.

18. The system of claim 12, wherein the heat storage unit is configured as a cartridge that is detachably securable to each of a plurality of different flowable product dispensers.
