  • Publication number: 20070256679
    Abstract: Self-contained disposable single-use heat-generating apparatuses and methods for providing heat are disclosed that have elastic member formed on at least a portion thereof. One exemplary apparatus includes a heat-generating pack having a first bag layer defined by a first surface area bonded to a second bag layer defined by a second surface area and creating one or a multiple pouches therebetween, an elastic member being disposed between at least two pouches. A heat-generating agent is disposed within the pouch(es) and adapted to consume air at a predetermined consumption rate in an exothermic reaction. At least a portion of one of the first surface area and the second surface area comprises an air permeable surface area having a predetermined airflow rate such that the heat-generating agent remains substantially evenly distributed within the pouches.
