Abstract
Disclosed are self-cooling containers for beverages and other liquids. Such containers comprise porous matrices as elements of the container bodies to effect the cooling of contained liquids by pervaporation. The liquid vapor can pass through the porous matrix directly to the environment or to a collector or trap comprising an absorbent material in contact with the container. Also disclosed are self-cooling containers incorporating insulative sleeves that reduce radiative warming of container surfaces yet permit sufficient pervaporative flux to cool containers residing within such sleeves.
