Abstract

A self heating pre-moistened wipe(s) package ( 10 ) includes a pre-moistened wipe(s) to be heated. The pre-moistened wipe(s) can be of variable size, shape, thickness and material, impregnated with a cleaning solution depending on the application. Within said outer package ( 10 ) is a thermal insulated layer ( 11 ). Enclosed in said packaging is a solvent activated exothermic chemical pad, powder, liquid or gel, enclosed in an absorbent envelope ( 21 ), a bag containing solvent ( 20 ) and a pouch for a pre-moistened wipe(s) ( 13 ). Enclosed within said package is a trigger mechanism to initiate the reaction either through a pull-tab means or through a pressure/rupturing means. Said trigger mechanism is affixed to said solvent bag ( 20 ) so that when triggered, the solvent within can flow out to trigger the exothermic reaction.
