[0016] FIG. 5 is an arrangement of stacks of 13 stackable carts of FIG. 1 that would allow 38 stacks to be placed within a standard 40-foot shipping container.

[0017] While embodiments of the disclosure are amenable to various modifications and alternative forms, specifics thereof shown by way of example in the drawings will be described in detail. It should be understood, however, that the intention is not to limit the disclosure to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the subject matter as defined by the claims.

DETAILED DESCRIPTION

[0018] Referring to FIGS. 1-4, a stackable cart 100 is depicted in accordance with an embodiment of the disclosure. The stackable cart 100 is configured to allow the stackable cart 100 to be nested within another stackable cart 100 such as shown in FIGS. 2-3.

[0019] The stackable cart 100 includes a tub 110, a plurality of wheels 120, and a handle 140. The wheels 120 of the stackable cart 100 are preferable connected by an axle 125, but can also be individually attached to the tub 110. The tub 110 has a stand 150 with a lowermost extremity that is level with the lowest part of the wheels 120. This arrangement allows the stackable cart 100 to be level with a round surface 500 when in a resting position. The tub 110 includes a wheel cutout 170 for each wheel 120 that allows the wheels 120 to fit within the profile of the tub 110 and not extend to the outside wall 180 of the tub 110. The wheel cutouts 170 are sized to allow the stand 150 of one stackable cart 100 to fit between the wheel cutouts 170 of another stackable cart 100 into which the stackable cart 100 is to be nested (see FIG. 4).

[0020] The interior volume 130 of the tub 110 of the stackable cart 100 is dimensionally sized to accept the lower portion 160 of a second stackable cart 100 nested within it. The lower portion 160 of the stackable cart 100 is defined as the portion of stackable cart 100 below the tub shoulder 165. The tub 110 of the stackable cart 100 includes an upper tub edge 105 that runs around the upper perimeter of the tub 110.

[0021] A significant advantage of the stackable cart 100 over prior art carts is the ability to stack the carts in a vertical manner by nesting a stackable cart 100 within a second stackable cart and then nesting those stackable carts 100 within another stackable cart. As seen in FIG. 5, the optimal arrangement 300 minimizes the volume of multiple stackable carts 100 to lessen the cost of transport and storage of the stackable cart 100. The arrangement allows for 13 stackable carts to be nested to have a height 420 that fits within the interior height of a standard 40-foot shipping container (7′ 10″).

[0022] The stackable cart 100 has a length 210 and width 220 such that 38 stacks 310 of 13 stackable carts 100 can fit within the interior of a standard 40-foot shipping container. FIG. 5 provides the arrangement of stacks 310 that will allow 494 stackable carts to fit within a standard shipping container with a width 410 not to exceed 7′ 6″ and a length 400 not to exceed 39′ 6″.
