DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS

[0020] Turning now to the remaining drawings, in which like numerals indicate like (but not necessarily identical) elements throughout the figures, example embodiments are described in detail.

Overview

[0021] Delivering eggs purchased from an online retailer in cartons can result very high egg breakage rates, especially if the online retailer uses a common carrier for delivery. Egg breakage rates can increase if the egg carton is delivered in the same overall package, for example a cardboard box, along with heavy products or products packaged in hard-sided containers. A typical egg carton is not designed to withstand the forces likely to be encountered by the eggs being handled like books, clothing, and other goods delivered by common carriers. Even specialty carriers, accustomed to transporting fragile items, can see unacceptable breakage rates. Private testing has shown breakage rates as high as 44% for 6-count and 12-count egg cartons shipped for overnight delivery in outer boxes with other grocery products.

[0022] Embodiments of the technology disclosed herein include devices, systems, and methods for supplementing a typical egg carton with an insert that can reduce the rate of egg breakage during transport. Some embodiments disclosed herein have demonstrated breakage rates of less than 3%.

Example Architectures

[0023] Referring to FIG. 2, and continuing to refer to prior figures for context, a first embodiment of an egg carton insert 200 is illustrated in perspective view, in accordance with example embodiments of the technology disclosed herein. The illustrated egg carton insert 200 is a six row 202a-202f by two column 204a-204b array of domes 210. While 62 is the most common egg carton 100 configuration, the egg carton insert 200 can be sized to any commonly-used N rowM column egg carton 100, such as 44, 63, etc.

[0024] Each dome 210 in FIG. 2 is shaped and sized to enclose a top portion of an egg. In some embodiments, the dome is shaped and sized to enclose less that the portion of an egg above its largest substantially round cross section. Other dome forms, including a truncated dome with a solid top, a truncated dome with an open top, and a pyramidal dome, can be used. In the example embodiment of FIG. 2, each dome 210 includes a substantially cruciform feature 240 that can facilitate orienting each egg top portion in its corresponding dome 210. Egg carton inserts 200 can be made from other materials, such as foamed plastics, rubber, clear plastic, and felt.

[0025] Each dome 210 can be connected to each neighboring dome in the array. In the example embodiment of FIG. 2 representing a pulp insert, each dome 210 is connected to each neighboring dome 210 at the dome edge, including by a small bridge 220. In other embodiments, each dome 210 can be connected to neighboring domes 210 without the use of a bridge 220.

[0026] The array of domes 210 forms an opening 230 between each group of four adjacent domes 210. Each opening 230 can receive a cone 116 of the egg carton 100. Inserting a cone 116 into one or more of the openings 230 can provide lateral stability to the combined egg carton 100 and egg carton insert 200. The loose, but laterally restrained, coupling between the egg carton insert 200 and the egg carton 100 can contribute to the protection of the eggs contained in the egg carton 100. The egg carton insert 200 is arranged such that each dome 210 corresponds to a dimple 112 of an egg carton 100 into which the egg carton insert 200 can be placed.

[0027] The overall dimensions of the egg carton insert 200 are such that the egg carton 100 can be closed when the egg carton insert 200 is placed over each egg occupying a dimple 116 of the egg carton 100.

[0028] In some embodiments, at least one dome 210 defines therein a cutout 212 along a portion of the at least one dome at a long side of the array. The cutout 212 is oriented substantially parallel to the long side of the array. The cutout 212 can be in the shape of an arch, a rectangle, or other shape for providing clearance for egg carton 100 features that would otherwise impede closing the egg carton 100 over the egg carton insert 200 when the egg carton 100 dimples 112 are holding eggs.

[0029] Referring to FIG. 3, and continuing to refer to prior figures for context, a second embodiment of an egg carton insert 300 is illustrated in perspective view, in accordance with example embodiments of the technology disclosed herein. The illustrated egg carton insert 300 is a substantially flat 62 array of rings 310 defining holes therein. While 62 is the most common egg carton 100 configuration, the egg carton insert 300 can be sized to any commonly used N rowM column egg carton 100. The length of the egg carton insert 300 is less than the interior length of an egg carton 100. The width of the egg carton insert 300 is less than the interior width of an egg carton 100. The thickness of the egg carton insert 300 is less than one half the height of an egg to be carried in the egg carton 100. The overall dimensions of the egg carton insert 300 are such that the egg carton 100 can be closed when the egg carton insert 300 is placed over one egg occupying each dimple 166 of the egg carton 100.

[0030] Each ring 310 in FIG. 3 defines therein a hole 320 shaped and sized to fit over a top portion of an egg placed in an egg carton 100. In some embodiments, each ring 310 defines a hole 320 therein that is shaped and sized to encircle the egg above its largest substantially round cross section, leaving a portion of the egg projecting through the ring 310. While the outer portion of the ring 310 illustrated in FIG. 3 is substantially circular, other ring forms, including various regular polygons and truncated polygons, can be used. The hole 320 formed by each ring 310 is aligned with a corresponding dimple 116 of the egg carton 100.

[0031] Each ring 310 is connected to each neighboring ring 310 in the array. In the example embodiment of FIG. 3 representing a pulp insert, each ring 310 is connected to each neighboring ring 310 at the ring edge. Egg carton inserts 300 can be made from other materials, such as foamed plastics, rubber, clear plastic, and felt.

[0032] The array of rings 310 forms an opening 330 between each group of four adjacent rings 310. Each opening 330 can receive a cone 116 of the egg carton 100. Inserting a cone 116 into one or more of the openings 330 can provide lateral stability to the combined egg carton 100 and egg carton insert 200. The loose, but laterally restrained, coupling between the egg carton insert 300 and the egg carton 100 can contribute to the protection of the eggs from damage. The egg carton insert 300 is arranged such that each ring 310 corresponds to a dimple 112 of an egg carton 100 into which the egg carton insert 300 can be placed.

[0033] Referring to FIG. 4, and continuing to refer to prior figures for context, a third embodiment of an egg carton insert 400 is illustrated in perspective view, in accordance with example embodiments of the technology disclosed herein. In the egg carton insert 400 of FIG. 4, each odd-numbered ring position of the egg carton insert illustrated in FIG. 3 in the second column 420 each is vacant, and each even-numbered ring position of the egg carton insert illustrated in FIG. 3 in the first column 410 is vacant.
