The structure of claim 2 wherein said first and second side walls each have the opposed side edges thereof diverging slightly relative to each other, said side glue flaps being integral with said opposed edges of said first side wall and with one of said opposed edges of said second side wall for selective folding relative thereto for engagement with adjacent side walls.
- 4. The structure of claim 3 including lock means on said first and second side walls adjacent the respective outer edges thereof, and cooperating lock means on said top panel adjacent the corresponding top panel edges thereof.
- 5. For use in the formation of a folded covered carton, a planar blank of foldable material, said blank including a bottom panel with a periphery defined by angularly related straight edges, first, second and third side wall panels respectively integrally joined to three of said edges along fold lines and projecting outwardly coplanar therefrom, said first and second wall panels having opposed side edges and projecting outward from first and second adjacent ones of said bottom panel edges, said third side wall panel projecting outward from a third one of said bottom panel edges spaced from said first and second adjacent bottom panel edges by intermediate ones of said bottom panel edges, said third side wall panel having opposed side edges, fourth and fifth side wall panels positioned laterally, coplanar, adjacent and integral with said third side wall panel respectively along said opposed side edges thereof with corresponding fold lines defined along each of said side edges of said third side wall panel, said fourth and fifth side wall panels being of the same size as said third side wall panel, said fourth and fifth side wall panels each having a side edge laterally outward of said third side wall panel, glue flaps coplanar and integral with selected ones of said side edges of said side wall panels along fold lines, a top panel with edges defining a periphery of the same configuration as that of said bottom panel, said third bottom panel side wall panel having an outer edge integrally joined to one of said top panel edges along the length thereof, and top panel walls projecting outward from said top panel edges other than said top panel edge integrally joined to said third bottom panel side wall panel, said top panel walls having opposed end edges with glue flaps integral with selected ones of these end edges.
- 6. The blank of claim 5 wherein said bottom panel and said top panel are each of a pentagonal configuration, said top panel edges being of greater length than the corresponding ones of said bottom panel edges.
- 7. The blank of claim 6 wherein said bottom panel intermediate edges are free edges.
- 8. The blank of claim 7 wherein said bottom panel edges are of equal length, and said top panel edges are of equal length.
- 9. A pattern layout for folding blanks for cartons comprising a planar sheet of material, first and second planar duplicate blanks defined from said sheet, said second blank being inverted relative to said first blank, both end-for-end and side-for-side, each blank including a bottom panel with first and second side panels diverging outward relative to each other from said bottom panel and defining a first end portion of said blank, a third side panel extending from said bottom panel generally diametrically opposed from said first and second side panels, fourth and fifth side panels extending laterally from opposite sides of said third side panel and combining therewith to define a central area of said blank, and a top panel extending from said third side panel generally diametrically opposed from said bottom panel and defining a second end portion of said blank, said fourth side panel having an elongate outer edge with said adjacent blanks defined with said fourth side panel outer edges co-extensive for definition by a single severance line through said sheet, said first end portion of each of said adjacent blanks partially nesting between said fourth side panel and second end portion of the adjacent inverted blank for minimization of scrap between said blanks.
- 10. A closable carton for foodstuffs and the like formed from a unitary blank, said carton comprising an upwardly opening receptacle and a lid for said receptacle selectively pivotable to a closed position over said receptacle; said receptacle including a bottom panel with peripheral edges and with peripheral receptacle walls of a predetermined height joined to said bottom panel and extending upward relative to respective ones of said bottom panel edges, selected ones of said receptacle walls being integral with said bottom panel, and glue flaps on other selected ones of said receptacle walls overlying and bonded to said bottom panel and securing said other selected ones of said receptacle walls to said bottom panel, said receptacle walls terminating in upper edges in a common plane, said receptacle walls having joined side edges defining angular corners and forming an enclosure; said lid including a top panel dimensionally greater than said bottom panel and with peripheral edges defining a periphery and corresponding to the peripheral edges of said bottom panel, said top panel including an inner face adapted for engagement on said receptacle wall upper edges peripherally about said receptacle for a direct support of said top panel by said receptacle walls, said lid including lid walls corresponding to respective receptacle walls and of a lesser height than said receptacle walls, said lid walls having edges foldably joined to at least a majority of said top panel edges and extending laterally inward from said inner face of said top panel and terminating in free edges wherein said lid walls, with said lid in said closed position, overlie the corresponding receptacle walls laterally outward thereof with said outer edges of said lid walls terminating in spaced relation upward of said receptacle bottom panel.
- 11. The carton of claim 10 wherein said receptacle and said lid are of a pentagonal configuration with said receptacle walls comprising a back wall, two side walls diverging outwardly from the opposite side edges of said back wall and defining corners therewith, and two front walls forming corners with and converging forwardly from said side walls and further defining a forward corner, the upper edge of said back wall, and one of said top panel edges being integrally joined with a hinge-providing fold line defined therealong, said receptacle walls flaring outward from said bottom panel and defining an upper periphery substantially co-extensive with the periphery of said lid top panel for nesting immediately inward of said lid walls in said closed position, said lid walls defining corners complementary to the corners of said receptacle walls and aligned therewith.
- 12. The carton of claim 11 including a selectively releasable and reengageable lock assembly securing said lid to said receptacle in said closed position of said lid with said lid top panel peripherally seating on said upper edges of said receptacle walls.
- 13. The carton of claim 10 wherein said receptacle walls flare outwardly from said bottom panel with the upper edges thereof defining a periphery of equal size and shape, and co-extensive with the edges of said lid top panel for engagement of said upper edges of said receptacle walls at the juncture between said lid top panel and said lid walls, said lid walls defining corners directly aligning with and nesting with said corners formed by said receptacle walls to define braced column-like structures.
