Abstract:
1. A refreezable container comprising: a bottom surface comprising a bottom interior cavity and a lower ridge and a lower groove, wherein said lower ridge and said lower groove are adapted for engagement with a lower adjacent object, wherein the bottom interior cavity is at least partially filled with refreezable material; at least one side surface contiguous with the bottom surface, wherein each at least one side surface comprises a side interior cavity separate from the bottom interior cavity and a top comprising a lip adapted for secure engagement with an upper adjacent object, and wherein the side interior cavity is at least partially filled with refreezable material, such that when the refreezable container is cooled, the refreezable material within the cavities retains contents of the refreezable container at a temperature lower than ambient temperature; and a top cover having a side cover surface, wherein the top cover comprises a lower cover groove adapted for secure engagement with the lip of the at least one side surface, an upper cover groove adapted for secure engagement with the lower ridge, and an upper cover ridge adapted for secure engagement with the lower groove, wherein the upper cover groove is positioned between the upper cover ridge and the side cover surface, and wherein the top cover comprises an upper interior cavity at least partially filled with refreezable material for enclosing contents of the refreezable container with refreezable material, wherein the lower groove of the bottom surface is adapted to engage the upper cover ridge of an adjacent top cover engaged with an adjacent refreezable container, thereby enabling multiple refreezable containers having top covers securely engaged thereon to be stacked for storage or transport or to provide additional refreezable material between the refreezable containers, and wherein the lower cover groove of the top cover is adapted to engage the upper cover ridge of the adjacent top cover, thereby enabling multiple top covers to be stacked for storage or transport or to provide additional refreezable material between the refreezable containers.
