ABSTRACT:
A refrigerating package is disclosed which comprises a multicompartment gussetted design in which the gusset is formed of a folded in or pleated section, with liquid being placed therein. The gussetted compartment is folded into another compartment and is sealed, the other compartment receiving a refrigerating chemical, the opening of the other compartment being sealed after the refrigerating chemicals are loaded therein. By direct application of pressure to the gussetted compartment, a rupture takes place allowing the liquid container therein to mix with the refrigerating chemical thus producing an endothermic or exothermic reaction, as desired.
