WARMING DEVICES WITH ELASTIC DISPOSED THEREIN AND METHODS OF WARMING
First Claim
1. A self-contained, disposable, single-use heat-generating apparatus, comprising:
- a heat-generating pack comprising;
a first bag layer having a first surface area;
a second bag layer having a second surface area, the second bag layer being fixed to the first bag layer, such that the first bag layer and the second bag layer define a plurality of pouches therebetween;
a heat-generating agent disposed in each pouch, the heat-generating agent arranged and configured to consume air at a predetermined air consumption rate in an exothermic reaction;
at least one of the first surface area and the second surface area comprises an air permeable surface area having a predetermined airflow rate at which air is introduced to the heat-generating agent, the predetermined airflow rate being arranged and configured to be less than the predetermined air consumption rate such that the heat-generating agent remains substantially evenly distributed within the pouch; and
an elastic member fixedly attached to at least one of the first surface area and the second surface area, the elastic member extending between two individual pouches.

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.

16. A method for providing therapeutic heat, comprising the steps of:
-
containing a heat-generating composition in a plurality of pouches in a self-contained heat-generating pack, the composition having a predetermined air consumption rate;
introducing air to the heat-generating composition at a predetermined airflow rate arranged and configured to be less than the air consumption rate such that the heat-generating composition remains substantially evenly distributed within the heat-generating pack; and
providing an elastic member, wherein the elastic member is a strip of elastic material bonded on each side to the pouches. - View Dependent Claims (17, 18, 19, 20, 21)
