PACKAGE FOR CHANGING TEMPERATURE OF PRODUCT STORED WITHIN IT DIRECTLY BEFORE OPENING OF PACKAGE Russian patent published in 2006 - IPC B65D81/34 A47J36/28 

FIELD: food-processing industry.

SUBSTANCE: package has thermal module located within thermally insulating casing and provided with activator including holder having at least one puncturing member positioned thereon and provided with sharpened end. Thermal module casing incorporates container sealingly connected therewith and adapted for storage of product, reactant in solid state and closed chamber made from readily puncturable material and filled with reactant in liquid state. Slots are provided on side wall of thermal module casing in the region at least opposite closed chamber incorporated therein, said slots being made in the form of channels or holes arranged at equal angular distance from one another. Part of internal surface of each of said slots is arranged at minimal distance from or adjoins said closed chamber. Thermally insulating casing has bottom and side wall bendable upon application by user of radial outer loading thereto. Holder for activator is positioned for accepting outer loading upon bending of side wall of thermally insulating casing and for urging radial movement of puncturing member positioned on holder, with sharpening end of puncturing member being located in respective slot provided through side wall of thermal module casing, opposite closed chamber. Distance between sharpened end of puncturing member and closed chamber filled with liquid reactant is smaller than maximal bending of side wall of thermally insulating casing.

EFFECT: increased efficiency in utilization of thermal effect of reaction between reactants, convenient usage and reduced package production costs.
