DETAILED DESCRIPTION OF THE INVENTION
[0035[ The present disclosure provides a system for stacking a plurality of insulated coolers, where the coolers can be the same size, or different sizes. Referring now to the drawing figures in which like reference designators refer to like elements, there is shown in FIG. I an exemplary stacking 10 of coolers of the present disclosure. The stacking 1.0 includes two different sized coolers vertically stacked. The base of the stack includes a first cooler 12 having a first size. A second cooler 14, equal in size to the first cooler 12 is positioned thereon. A third and forth cooler 16 and 18 are adjacently positioned on the second cooler 14, where the third and forth coolers 16 and 18 are sized to adjacently fit on top of the second cooler 14. A. fifth and sixth cooler 20 and 22 are one each positioned on top of the third and forth coolers 16 and 18, where the fifth and sixth coolers 20 and 22 have a size equal to the third and forth coolers 16 and 18.
[00361 Referring to FIGS. 2-4 a first cooler 12 of the present invention is provided. The first cooler 12 has an. insulated body 30 with a removable insulated lid 32.
The insulated body 30 and removable insulated lid 32 each have a length IL and a width wr., and combine to give the first cooler 12 a body height of hL,. The insulated body 30 can be rectangular in shape having front, back, bottom, and opposite side surfaces defining an interior cavity. A
top of the insulating body 30 is open, providing access to the interior cavity.
[00371 The insulated body 30 further includes a lower portion 34 extending from a bottom 36 of the insulated body 30 a distance hb. The lower portion 34 has a length Ii, which is less than the length lr. of the insulated body30, and a width wr, which is less then the width WL of the insulated body 30, such that the edge 36 of the lower portion 34 is indented in. from the bottom edge 40 of the insulated body 30.
[00381 The insulated lid 32 is removably positionable on an open top end 42 of the insulated body 30 to seal an interior cavity of the insulating body 30.
Referring to FIGS. 5-7 and 15 and as noted above, the insulated lid 32 has length 1L, width wL, and height h1,,. The insulated lid 32 further includes a lower portion 44 extending from a bottom surface 46 of the insulated lid 32. The lower portion 44 is sized to fit within the open end 42 of the insulated body 30.
[0039] The top surface 48 of the insulated lid 32 includes a raised outer edge 50 having a height he, and a thickness t, such. that the top surface 48 has an inner length 12 and an inner width w-,. A. curved surface 52 extends between the raised outer edge 50 and the top surface 48 of the lid 32.
100401 The raised outer edge 50 of the lid 32 is configured such that the lower portion 34 of the insulated body 30 can be fitted within the raised outer edge 50. In this manner, the inner length 12 of the top surface 48 of the lid 32 is slightly greater then the length 11 of the lower portion 34 of the insulated body 30. Similarly, the inner width w2 of the top surface 48 of the lid 32 is slightly greater then the width. w, of the lower portion 34 of the insulated body 30.
[0041] The edge 38 of the lower portion 34 of the insulated body 30 can. have a curved shape, which is substantially opposite to the curved surface 52 extending between the raised outer edge 50 and the top surface 48 of the lid 32. When the insulated body 30 is stacked, positioned, on top of the insulated lid 32, these surfaces mate, interlock, to substantially limit horizontal movement between the stacked insulated body 30 and insulated lid 32. While the curved shape of the edge 38 of the lower portion 34 of the insulated body 30 and the curved surface 52 extending between the raised outer edge 50 and the top surface 48 of the lid 32 are depicted and described as being curved, any shape and configuration can be utilized which would interlock the surfaces to resist horizontal movement there between.
