Abstract
A temperature modifying system for heating or cooling a product including a flexible outer container containing a product and a self-enclosed temperature-changing element is disclosed. The temperature-changing element includes a flexible pouch at least partially immersed in said product. The flexible film pouch may have two components separated by a rupturable barrier that is adapted to burst under an application of pressure allowing the two components to combine or react in an exothermic or endothermic event. The flexible film pouch may alternatively include a saturated salt solution that generates as it drops out of solution.
Claims29
A temperature-changing modifying system for heating or cooling a product, said system comprising:
- a. a flexible outer container containing a product;
- and
- b. a self-enclosed temperature-changing element comprised of a flexible pouch at least partially immersed in said product, said flexible pouch having a first component disposed in a first compartment, and a second component,
- c. wherein said temperature-changing element is entirely contained within said container,
- d. wherein a rupturable barrier of said temperature-changing element is adapted to burst under an application of pressure to allow said first component and said second component to mix and thereby modify a temperature of said product.
A temperature modifying system for heating, said system comprising:
- a. a flexible outer container containing a product;
- and
- b. a self-enclosed temperature-changing element comprised of a flexible pouch at least partially immersed in said product and said temperature-changing element containing a liquid which is a saturated salt,
- c. wherein another element is adapted to create a nucleation site under an application of pressure to allow said saturation salt to crystallize.
