Abstract

A portable cooler stacking system is provided, where portable coolers of different shapes and sizes can be optimally and stably stacked. The cooler system can include a first cooler having a first size and a second cooler having a second size, where the first and second sizes are different. A pair of second coolers can be stacked on the first cooler, where the second coolers are positioned widthwise along the length of the lid of the first cooler. In this manner, an inner length of the top surface of the lid of the first cooler is slightly greater then the width of a lower portion the second coolers and the inner width of the top surface of the lid of the first cooler is greater then two times the width of the lower portion of the second coolers. As such, two second cooler can be positioned widthwise along the length of the lid of the first cooler. The adjacent position of the second coolers and the interlocking surfaces substantially limit the horizontal movement of the pair of second coolers on the lid of the first cooler.

Claims

1. A stackable portable cooler system, comprising:

a first cooler including a lid having a raised peripheral edge; and

a second cooler including an indented lower bottom portion,

wherein the second cooler is positionable on the first cooler such that the indented lower bottom portion of the second cooler is positioned within the raised peripheral edge of the lid of the first cooler, the raised peripheral edge of the lid of the first cooler resisting a horizontal movement of the second cooler.

2. A stackable portable cooler system as set forth in claim 1, wherein the indented lower bottom portion of the second cooler includes a plurality of stabilizing feet.

3. A stackable portable cooler system as set forth in claim 1, wherein the first and second coolers are the same size.

4. A stackable portable cooler system as set forth in claim 1, wherein the first and second coolers are different sizes.

5. A stackable portable cooler system as set forth in claim 4, further comprising third cooler including an indented lower bottom portion,

wherein the third cooler is positionable on the first cooler, adjacent to the second cooler, such that the indented lower bottom portion of the third cooler is positioned within the raised peripheral edge of the lid of the first cooler, the raided peripheral of the lid of the first cooler resisting a horizontal movement of the second cooler.

6. A stackable portable cooler system as set forth in claim 5, wherein the second and third coolers are different sizes.

7. A stackable portable cooler system as set forth in claim 5, wherein the second and third coolers are the same size.

8. A stackable portable cooler system as set forth in claim 1, wherein the lid of said first cooler is hingedly connected to a cooler body of said first cooler.

9. A stackable cooler system as set forth in claim 1, wherein said first cooler further comprises at least one pair of wheels.

10. A stackable portable cooler system as set forth in claim 1, further comprising a foldable cart on which said cooler system may be stacked and wherein said foldable cart fits within the interior of at a first cooler of the cooler system when not in use.
