Abstract

A storage container having a basin defining an interior space, and comprising two or more partition walls; a freezer partition wall defining a freezer compartment, a chill partition wall defining a chilled compartment, a cooling chamber being defined between said partition walls, wherein each of said partition walls are configured, when a cooling medium is received within said cooling chamber, for allowing airflow therethrough to its respective compartment, thereby maintaining a temperature difference between said freezer compartment and chilled compartment.

First claim

The invention claimed is:

1. A storage container having a basin defining an interior space, and comprising two or more partition walls; a freezer partition wall defining a freezer compartment, a chill partition wall defining a chilled compartment, a cooling chamber being defined between said partition walls, wherein each of said partition walls are configured, when a cooling medium is received within said cooling chamber, for allowing airflow therethrough to its respective compartment, thereby maintaining a temperature difference between said freezer compartment and chilled compartment,
said cooling chamber is disposed intermediate said freezer compartment and said chilled compartment, and the freezer partition wall faces the freezer compartment and the chill partition wall faces the chilled compartment,
said the freezer partition wall is configured at a bottom portion thereof with a plurality of first frustoconical apertures, having a wider base at a face of the freezer partition wall that faces the freezer compartment and a narrower base at a face of the freezer partition wall that faces the cooling chamber,
said the chill partition wall is configured at a bottom portion thereof with a plurality of second frustoconical apertures, having a wider base at a face of the chill partition wall that faces the chilled compartment and a narrower base at a face of the chill partition wall that faces the cooling chamber, and
a total section area of the second frustoconical apertures being smaller than a total section area of the first frustoconical apertures, wherein when a cooling medium is received within said cooling chamber, directional airflow through the first and second frustoconical apertures maintains a temperature difference between said freezer compartment and said chilled compartment.

2. The storage container of claim 1 , wherein the storage container is configured for receiving within a housing container, said housing container configured with solid side walls and a lid, and wherein said lid admits access to removable covers of the storage container.

3. The storage container of claim 1 , said basin comprises an ambient compartment neighboring said chilled compartment with an ambient partition wall disposed therebetween.

4. The storage container of claim 2 , comprising external walls that comprise a base member, a right side wall, a left side wall, a front wall a back wall, at least one removable cover, wherein said external walls and said at least one removable cover and said partition walls are made of a thermally insulating material.

5. The storage container of claim 4 , wherein the base member, and the walls of the storage container and at least the freezer partition wall and the chill partition wall are configured for foolproof assembly at a pre-designed configuration.

6. The storage container of claim 3 , wherein the cooling chamber comprises a top cover extending over at least a portion of a cooling chamber space that is defined between the freezer partition wall, and the chill partition wall and a cooling medium support within said cooling chamber.

7. The storage container of claim 6 , wherein the top cover of the cooling chamber is configured with a child-proof arrangement, so as to prevent or reduce the likelihood of a child displacing the top cover between an open position at which the top cover can be opened to facilitate access into the cooling chamber space, and a closed position.

8. The storage container of claim 6 , wherein the cooling medium support within the cooling chamber is spaced apart from the base member of the storage container.

9. The storage container of claim 6 , wherein the cooling chamber is configured with one or two lateral flow paths, extending between a bottom space below the cooling medium support, and a top portion, above the cooling medium support.

10. The storage container of claim 6 , wherein a space below the cooling medium support is configured with air flow apertures, facilitating air flow between the freezer compartment and the chilled compartment.

11. The storage container of claim 2 , wherein when said cooling medium is received within the cooling chamber the cooling chamber is a lower-most, sub-zero temperature zone (T° Cc); the freezer compartment is configured as a sub-zero temperature zone (T° Fc); the chilled compartment is configured as a chilled temperature zone (T° CHc); and the ambient compartment is configured as an ambient temperature zone (T° Ac); wherein T° Cc<T° Fc<T° CHc<T° Ac.

12. The storage container of claim 2 , wherein the ambient partition wall is configured with throughgoing apertures configured for air circulation between the chilled compartment and the ambient compartment.

13. The storage container of claim 6 , wherein the cooling medium support within the cooling chamber is further configured with refrigerator apertures extending between the cooling chamber space towards a space below the cooling medium support, facilitating air flow in direction from the cooling chamber space towards said space below the cooling medium support.

14. The storage container of claim 5 , wherein walls of the container are assembled over the base member at a preset arrangement, by a foolproof arrangement, wherein mating edges of the walls and the base member comprise one or more projections configured at one or both of the walls and the base member, and the other one or both of the walls and the base member comprises respective indentions, in register with the projections, configured for unidirectional true positioning of said walls over the base member.

15. The storage container of claim 5 , wherein any one or more of the front wall, the back wall and the base member of the storage container are configured with a foolproof assembly arrangement, configured for unidirectional, true positioning, of the cooling chamber within the interior space.

16. The storage container of claim 5 , wherein any one or more of the partition walls is configured, at one or more of a bottom edge and side edges thereof, with depressions and/or projections disposed in register with opposite ones of depressions and/or projections configured at a bottom edge of the front wall and the back wall and the base wall, respectively.

17. A cooler container kit comprising a housing container configured with solid side walls and a lid, and a storage container of claim 1 snugly receivable with said housing container and where the lid admits access to the removable covers of the storage container.
