Abstract
Abstract The tray of the carton is divided into larger and smaller compartments by a transverse intermediate wall. The tray outer end wall at the smaller compartment is integrally formed with a lid panel folded to overlie the smaller compartment and extend laterally outward of opposed side walls of the tray. The intermediate wall is integral with and depends from the lid panel. A cover, with depending side walls, is integrally hinged to the second end wall of the tray with the cover side walls including forwardly extending lugs engagable with and beneath the transversely extending portions of the lid panel to releasably lock the cover in a closed position.

Claim 1
Independent Claim
294 words
A carton for the accommodation of first and second foodstuffs, said carton comprising a tray, said tray including a bottom with integral opposed elongate side walls extending upward therefrom, and integral opposed first and second end walls extending upward from said bottom transversely between said side walls, an intermediate wall extending transversely between said side walls at an intermediate position between said end walls, said intermediate wall extending upward from said tray bottom and defining first and second compartments to the opposite sides of said intermediate wall and between said intermediate wall and said first and second end walls respectively for the separated accommodation of foodstuffs; a cover for said first compartment, said cover having a top panel generally co-extensive with said first compartment, opposed side walls integral with said top panel and depending therefrom, and opposed inner and outer end walls integral with said top panel and depending therefrom transversely between said cover side walls, said cover outer end wall being integral with said tray first end wall along a hinge line wherein said cover is pivotally movable between a closed position overlying said first compartment with said cover inner wall substantially aligned with said tray intermediate wall, and an open position upwardly pivoted away from said first compartment; and a lid panel overlying said second compartment, said lid panel being substantially planar and having inner and outer edges respectively integral with said tray second end wall and said tray intermediate wall, said lid panel having co-planar opposed portions extending laterally outward beyond said opposed tray side walls, said cover side walls having longitudinally extending lugs overlapping the opposed extending portions of said lid panel transversely outward of said tray side walls and releasably snap-engaging therebeneath in the closed position of said cover.
Claim 2
Dependent Claim
294 words
A carton for the accommodation of first and second foodstuffs, said carton comprising a tray, said tray including a bottom with integral opposed elongate side walls extending upward therefrom, and integral opposed first and second end walls extending upward from said bottom transversely between said side walls, an intermediate wall extending transversely between said side walls at an intermediate position between said end walls, said intermediate wall extending upward from said tray bottom and defining first and second compartments to the opposite sides of said intermediate wall and between said intermediate wall and said first and second end walls respectively for the separated accommodation of foodstuffs; a cover for said first compartment, said cover having a top panel generally co-extensive with said first compartment, opposed side walls integral with said top panel and depending therefrom, and opposed inner and outer end walls integral with said top panel and depending therefrom transversely between said cover side walls, said cover outer end wall being integral with said tray first end wall along a hinge line wherein said cover is pivotally movable between a closed position overlying said first compartment with said cover inner wall substantially aligned with said tray intermediate wall, and an open position upwardly pivoted away from said first compartment; and a lid panel overlying said second compartment, said lid panel being substantially planar and having inner and outer edges respectively integral with said tray second end wall and said tray intermediate wall, said lid panel having co-planar opposed portions extending laterally outward beyond said opposed tray side walls, said cover side walls having longitudinally extending lugs overlapping the opposed extending portions of said lid panel transversely outward of said tray side walls and releasably snap-engaging therebeneath in the closed position of said cover.
Claim 3
Dependent Claim
20 words
The carton of claim 1 wherein said lid panel seats on said tray side walls and is partially supported thereby.
Claim 4
Dependent Claim
28 words
The carton of claim 2 wherein said intermediate wall extends perpendicular to said lid panel and said tray bottom and engages said tray bottom for direct support thereby.
Claim 5
Dependent Claim
22 words
The carton of claim 3 including an aperture defined centrally through said lid panel for the selective reception of a foodstuff therein.
Claim 6
Dependent Claim
50 words
The carton of claim 4 including a locking tab integral with said intermediate wall adjacent a lower edge thereof and laterally folded relative to said intermediate wall, said tray bottom having a slot defined therein and receiving said tab therethrough for a fixing of said intermediate wall to said bottom.
Claim 7
Dependent Claim
53 words
The carton of claim 5 wherein said locking tab is directed toward said second compartment and in underlying relation thereto, said intermediate wall having an integral flange folded therefrom and extending to the opposite side of said intermediate wall from said tab and into said first compartment in overlying relation to the bottom.
Claim 8
Dependent Claim
45 words
The carton of claim 6 wherein said tab includes an enlarged leading head with opposed shoulders inwardly directed toward said intermediate wall, said slot defining projections engaging said shoulders upon extension of said locking tab through said slot wherein withdrawal of the tab is precluded.
Claim 9
Dependent Claim

Claim 14
Dependent Claim
222 words
For use in the formation of a folded carton, a longitudinally extending planar blank of foldable material, said blank comprising a cover top panel, longitudinally extending cover side walls integral with said top panel with fold lines defined therebetween, first and second cover end walls integral with said top panel with fold lines defined therebetween, an elongate tray bottom panel longitudinally aligned with said top panel, said bottom panel having opposed side walls integral with said bottom panel with fold lines therebetween, first and second transversely extending tray end walls integral with said bottom panel with fold lines therebetween, said first tray end wall being integral with said first cover end wall with a hinge line defined therebetween, a lid panel integral with said tray second end wall and foldable relative thereto, said lid panel being devoid of fold lines extending longitudinally on said blank, said lid panel having a transverse width greater than the transverse width of said bottom panel and less than the combined transverse width of said bottom panel and said tray side walls, said tray side walls and said tray second end wall being of equal height whereby said lid panel, in said carton, directly overlies and seats on said tray side walls with said lid panel extending transversely beyond said tray side walls in a single plane.
