ABSTRACT:
The present invention provides a tote bag equipped with a flexible, durable and lightweight cooling chamber. The cooling chamber is comprised of a cooling compartment secured to an uninsulated portion of a tote bag, a cooling chamber housed within the compartment, a flexible external housing member which externally circumscribes the chamber and forms a protective covering, a flexible insulative liner internally disposed within the housing member and enveloping the cooling chamber and a cooler compartment accessing port for access to the cooling chamber. The cooling compartment may also be equipped with means for removing the insulative liner from the housing member and also for detachably removing the housing member from the uninsulated portions of the tote bag. Flexible insulative liners containing a multiplicity of closed gas cells uniformily distributed throughout a flexible plastic sheet or film such as bubble packs used in the packaging industry are particularly well suited for the insulated tote bag of this invention.
