Abstract

A heating system comprising a pouch, into which one or more single-use packettes are placed for heating. In preferred embodiments, the pouch comprises printed heating elements, printed circuit elements and a means of connecting to a power source. Power may be supplied through a USB-type connector or a handheld power supply that is custom designed to work with the heating pouch.

First claim

What we claim is:

1. A packette heating system comprising:
a heating pouch that comprises:
top and bottom panels having:
respective first perimeter portions that are permanently bonded together to form a reservoir between the two panels, the reservoir measuring 25 mm-150 mm by 25 mm-150 mm;
respective second perimeter portions that form a pouch opening that leads into the reservoir; and

one or more heating elements that are in physical contact with at least one of the panels, wherein each heating element:
is a continuous resistive electric path that has a positive terminal and a negative terminal located near the first perimeter portion of that panel on which the heating element is located;
has a resistance between 1Ω and 15Ω, and is able to convert electrical energy into heat at a rate of 5 watts to 10 watts; and
comprises a positive thermal coefficient ink that is printed onto the exterior surface of the top or bottom panel; and

a power cable having two metal clamps at one end, and a USB-type connector at the other end for connecting an external power source to the positive and negative terminals of the heating packette, wherein the voltage of the power source is in the range of 1.5 V to 12 V;
wherein the pouch is configured with an integrated circuit having programmed instructions, and the USB-type power cable is able to transfer data to and from the pouch.

2. The heating pouch of claim 1 wherein the top and bottom panels are 25μ to 100μ thick.

3. The heating pouch of claim 1 wherein the pouch opening is resealable.

4. The packette heating system of claim 1 wherein the external power source comprises one or more batteries.

5. A method of using a packette heating system of claim 1 comprising the steps of:
inserting a packette into the reservoir of the pouch;
attaching the metal clamps of the power cable to the positive and negative terminals of the heating element;
inserting the USB-type connector into a USB jack that can provide electric power such that electricity flows through the heating element;
allowing electricity to flow through the heating element for a time sufficient to heat the product in the packette to a product application temperature;
stopping the flow of electricity; and
removing the packette from the heating pouch.
