Abstract: A portable carrier for transporting pharmaceutical preparations while protecting those preparations against degradation by ambient temperature conditions, which carrier comprises three blocks of expanded polystyrene foam. One of these three blocks is a central body block having a bore extending vertically therethrough; the second is a base block; and the third is a lid block hingedly connected to the central body block. The lid and top of the body block have contact cement applied thereto such that the lid is repeatedly operable and sealingly reclosable. A sealed, hollow, plastic ball containing refreezable liquid is locatable within the bore of the body block along with a vial of medication so as to maintain that medication at a refrigerated temperature.
