Abstract
Abstract An egg carton, having two rows of cavities of six each, has the cavities separated from each other longitudinally by integrally formed walls extended upwardly with projecting tips (29), and transversely by at least one transverse wall extending across the carton structure, the walls having sloping sides and meeting at a point intermediate the depth of the cavities to provide for easy egg removal, while cradling the eggs; in one form, the top cover has a depression of sufficient depth to bear against a transverse wall between cavities.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
228 words
Molded egg carton structure to hold one dozen eggs in two rows of six each, said structure comprising: a bottom tray section (10) and a top cover section (30) movably secured to said bottom tray section, said bottom tray section including a plurality of contoured walls (11, 12, 13, 14, 15) defining egg-receiving cavities (21, 22, 23, 24) therebetween, open at the top and arranged in two rows of six each, adjacent transverse walls (17, 18) and longitudinal walls (19) between egg-receiving cavities being integrally connected, the walls (19) between the rows of cavities being extended upwardly to form projecting tips (29) located centrally of said cavities and having downwardly sloping side walls (28); at least one partition wall (27) being provided between two adjacent cavities of a row being of substantially the same height as said projecting tips and extending across said rows of said cavities in the carton structure, each partition wall having sloping sides (25) meeting the sloping side walls (28) of said tips at a level below the top edge of the partition walls and said tips to permit ready removal of eggs while providing protection over an extended area around the egg; and said top cover section (30) being essentially boxshaped and fitting against said tray section and including a flat cover panel (31) and side panels (32, 33, 34, 35) extending therefrom.
Claim 2
Dependent Claim
228 words
Molded egg carton structure to hold one dozen eggs in two rows of six each, said structure comprising: a bottom tray section (10) and a top cover section (30) movably secured to said bottom tray section, said bottom tray section including a plurality of contoured walls (11, 12, 13, 14, 15) defining egg-receiving cavities (21, 22, 23, 24) therebetween, open at the top and arranged in two rows of six each, adjacent transverse walls (17, 18) and longitudinal walls (19) between egg-receiving cavities being integrally connected, the walls (19) between the rows of cavities being extended upwardly to form projecting tips (29) located centrally of said cavities and having downwardly sloping side walls (28); at least one partition wall (27) being provided between two adjacent cavities of a row being of substantially the same height as said projecting tips and extending across said rows of said cavities in the carton structure, each partition wall having sloping sides (25) meeting the sloping side walls (28) of said tips at a level below the top edge of the partition walls and said tips to permit ready removal of eggs while providing protection over an extended area around the egg; and said top cover section (30) being essentially boxshaped and fitting against said tray section and including a flat cover panel (31) and side panels (32, 33, 34, 35) extending therefrom.
Claim 3
Dependent Claim
75 words
Egg carton structure according to claim 1, wherein two partition walls are provided extending across the carton structure, located symmetrically in said structure and between cavities No. 2 and 3, and 4 and 5 in a row of cavities; and the transverse walls (FIG. 2: 17, 18) between the remaining cavities of opposite rows are extending upwardly to form projecting tips located centrally of said cavities of each row and having downwardly sloping side walls.
Claim 4
Dependent Claim
48 words
Egg carton structure according to claim 2, wherein the downwardly sloping side walls of the tips separating the cavities in the rows and the cavities across the rows, converge to a flat platform (5) located intermediate four cavities and symmetrically with respect to each one of the cavities.
Claim 5
Dependent Claim
36 words
Egg carton structure according to claim 1, wherein each of the cavities in a row is separated from an adjacent cavity by a partition wall extending across said rows of the cavities of the carton structure.
Claim 6
Dependent Claim
70 words
Egg carton structure according to claim 1, (FIGS. 5 and 6), wherein the cover panel (131) of the cover section (130) has at least one depression (137) formed therein extending transversely to said carton structure and located in alignment with a partition wall (27) of the tray section, said depression terminating in a bearing strip (138) having an inner surface bearing against the top surface of said partition wall (27).
Claim 7
Dependent Claim
48 words
Egg carton structure according to claim 5, wherein each cavity in a row is separated from an adjacent cavity by a partition wall (FIG. 5: 27) extending across said rows of the cavities of the carton structure, said depression of the top section bearing against a partition wall.
Claim 8
Dependent Claim
19 words
Egg carton structure according to claim 5, wherein said depression (137) in the cover section is centrally positioned therein.
Claim 9
Dependent Claim
42 words
Egg carton structure according to claim 1, wherein the top of said walls (17, 18, 19, 27) located between said cavities is essentially at the same level as the top of the contoured walls (11, 12, 13, 14) defining the egg-receiving cavities.
Claim 10
Dependent Claim
30 words
Egg carton structure according to claim 1, including separable, interengaging locking means (40, 45) secured to said top and said bottom sections, respectively, to releasably hold said sections closed together.
Claim 11
Dependent Claim
111 words
Egg carton structure according to claim 9, wherein said cover section is attached along at least one longitudinal side wall (32) to said tray section by an integral hinge strip and said interengaging locking means includes: an integral locking strip (45) located along the other longitudinal side and foldable inwardly of said cover, the adjacent side panel (32) of said top section and said strip (45) being formed with projections (46, 47) extending inwardly of said boxshaped structure; and a locking tab strip (40) integral with the tray section and extending therefrom and formed with depressions (41) matching the projections (46, 47) on said top section strip and releasably engageable therewith.
Claim 12
Dependent Claim
37 words
Egg carton structure according to claim 10, wherein the other longitudinal side panel (34) of said top cover section is formed with inwardly extending projections (48) similar to the projections (46) on the other side panel (32).
Claim 13
Dependent Claim
