Dependent Claim 86 words
The carton of claim 3 wherein said cover front wall includes opposed end edges, said cover side walls including forward portions overlying said front wall end edges, said front wall end edges each being partially spaced from the corresponding side wall forward portion and defining, in the closed position of the cover, a downwardly directed notch, said side walls of said tray section including a pair of transversely aligned upwardly directed cover support shoulders received within said notches and defining the closed position of said cover.
Claim 6
Dependent Claim 90 words
The carton of claim 4 wherein each cover side wall includes a forward projection extending beyond said cover front wall and, in the closed position of said cover, in partially overlying relation to said second compartment side walls, each said second compartment side wall having an inwardly directed edge, and a latching lug extending from said inwardly directed edge in vertically spaced relation above each of said support shoulders, each said lug, in the closed position of said cover, engaging over and downwardly latching the corresponding cover side wall projection.
Claim 7
Dependent Claim 25 words
The carton of claim 5 wherein each cover side wall projection includes an upwardly directed recess therein aligning with and receiving the corresponding latching lug.
Claim 8
Dependent Claim 42 words
The carton of claim 5 wherein said cover includes a top panel with opposed back and front edges, and opposed side edges from which the cover walls extend, said top panel having finger-accommodating lift means thereon for hand manipulation of said cover.
Claim 9
Dependent Claim 35 words
The carton of claim 7 wherein said second compartment outer end wall and said cover front wall, when said cover is closed, converge downwardly toward each other, said cover front wall terminating above said base.
Claim 10
Dependent Claim 42 words
The carton of claim 8 wherein said cover back wall is of substantially the same height as said first compartment outer end wall wherein said cover, in the open position thereof, can be positioned adjacent and substantially coplanar with said first compartment.
Claim 11
Dependent Claim 17 words
The carton of claim 8 wherein said base is transversely arcuate between the opposed side edges thereof.
Claim 12
Dependent Claim 32 words
The carton of claim 10 wherein said opposed first compartment side walls, adjacent said first outer end wall, each include an upwardly directed projection for guiding said cover to said closed position.
Claim 13
Dependent Claim 24 words
The carton of claim 3 wherein said carton is formed from a unitary blank of foldable shape-sustaining material, said blank including integral glue flaps.
Claim 14
Dependent Claim 28 words
The carton of claim 7 wherein said lift means comprises a pair of tabs defining extensions from said top panel and extending beyond said opposed cover side walls.
Claim 15
Dependent Claim 29 words
The carton of claim 7 wherein said lift means includes a pivotal flap within said top panel adjacent said cover front wall, and an aperture defined by said flap.
Claim 16
Dependent Claim 243 words
A unitary blank of foldable shape-sustaining material comprising an elongate bottom panel with first and second opposed outer end edges and opposed side edges, first and second outer end walls coextensive respectively with said first and second outer end edges with fold lines defined along said end edges, said second end wall terminating in a free outer edge and having opposed side edges with coextensive side walls extending therefrom and with fold lines defined therebetween, said first end wall being of a substantially lesser width outward from said corresponding bottom panel end edge than said second end wall, a cover back wall of substantially equal width with said first end wall immediately outward thereof and with a hinge-defining fold line therebetween, a cover top panel integral with and outward of said cover back wall with a fold line therebetween, said top panel being of a length, outward from said cover back wall less than the length of said bottom panel outward from said first end wall whereby said top panel, upon closure over said bottom panel will extend only partially toward said second end wall, said cover having a front wall integral with the top panel and opposed from said back wall, said front wall terminating in a free outer edge remote from said top panel, said second end wall having a width outward from said top panel greater than the combined width of said first end wall and said cover back wall.
Claim 17
Dependent Claim 243 words
