Abstract
A portable cooler that maintains a desired low temperature for beverages within conventional consumer containers. The cooler is made up of two molded insulating storage container halves, having matching indentations for receiving a number of beverage containers. The halves close over the containers, bringing a previously refrigerated, removable cold pack into contact with the enclosed containers. The beverage containers are thus cooled by direct contact with the cold pack and by direct contact with one another. The joined halves are removably received within a pocket of a fabric carrier that allows the entire unit to be hand-held or carried on the belt of the user.
