Abstract:
A gelling cold pack comprising:a disposable container, wherein the container comprises:at least one liquid-impermeable, heat-conducting first zone containing a composite particulate first material capable of interacting with a liquid second material to produce cold, to which particles of a gelling agent are adhered as a permeable, non-continuous coating;at least one liquid-impermeable, heat-conducting second zone containing said second material with which said first material in said first zone can interact to produce cold;a separator disposed between said first and second zones, the separator being manually operable to provide communication between said zones,wherein communication between the zones initiates gelation of the gelling agent to produce a gel in the container, and wherein said communication initiates the interaction of said first and said second materials, resulting in the generation of cold within the container.
