How does the QVC product cool touch work?
Posted by admin
Justin Bass asked:
QVC sells this product that is basically a cooling pad powered by human heat. You sit on the pad and it starts cooling down. This really doesnt make sense, i have a theory but i dont know if its right. See supposedly you have to keep it at 70 degrees for a little while every week or else it wont work, and also the only info i could find on it was that it cools by turning a crystal into a gel. So im thinking maybe its some kind of endothermic reaction that requires very little heat to start up? And then the crystals break down from the heat and absorb heat, in essence cooling down. And to turn back into crystals, the gel needs to be cooled? I dont know, but the product actually does work, and very well. Please explain someone.

POSSIBLY THE PATENT OR A PATENT TO ONE LIKE IT.
A hot or cold chemical therapy pack (1) is provided that has two compartments (28, 30). One compartment (28) has a natural weak point (32) or seam (at 24 or 26) and is contained inside the other compartment (30). Each compartment contains a chemical reactant. In one embodiment, the outer compartment (30), which is made of a flexible, vinyl or plastic material, is arranged in a semi-collapsed configuration. Each end of the inner compartment (28) is fixedly attached to a respective end (24, 26) of the outer compartment (30). The pack (10) is chemically activated by pressing on, kneading, or twisting the outer compartment (30), or pulling on each end of the pack (10). The lateral, outward pressure caused by the pressing on, kneading, or twisting of the pack, or by the user’s pulling on the ends of the pack, is exerted at the rupturable seam (32) of the inner compartment (28). At a predetermined pressure, the natural weak point (32) or seam is ruptured and the reactant contents of the two compartments merge (34), which creates the heating (exothermic) or cooling (endothermic) chemical reaction. Consequently, the hot or cold chemical therapy pack (10) is more easily activated than existing chemical therapy packs, which makes this pack (10) more convenient to use.
*****************************
Scientific formulation of natural minerals transfers body heat to Cool Touch® comfort cushion minerals from a firm gelatin/crystalline consistency to liquid state. Cool Touch® comfort cushion cools for hours before needing to regenerate its cooling ability over and over again.
Cool Touch® Support Cushion
Place Cool Touch® Support Cushion in a cool place such as shade, ice chest, refrigerator, anywhere it is 75 F or cooler until the cushion resolidifies to a gelatin/crystaline consistency, it’s then ready to use again and again! Regeneration time varies from 15 minutes to several hours depending in the temperature of the cushion and the temperature where it is placed to cool down.
Place Cool Touch® Comfort Cushion will become firm as it cools below 75 F and hard as it becomes even cooler. Below 45 F the cushion may become quite hard, this is normal. In cold climate areas after winter storage, place cushion in a relatively warm area such as a sunny porch or warm car interior to warm the cushion and allow the contents to ‘liquify.’ Then follow normal instructions above to enjoy the Comfort Cushions cool soothing effect all summer long!
Note: Do not place Cool Touch® Support Cushion in water or wet environment where foam insert may become wet.
