Abstract
Abstract A laminated or multi-layer wall carton or tray is provided which has a self-supporting outer layer or wall portion of paperboard which may be a laminated structure and may include a paperboard with a plastic, foil or a paper layer laminated thereto. The laminated layer of material may be adhered to the surface on one or on both sides of the paperboard, preferably before the tray or carton is die cut and formed. The carton includes a gusset fold and overlap at the corners for a leakproof construction and is concerned with the provision of a single gusset fold or a multiple gusset fold which may be heat sealed or glued in place. A plastic liner is either thermo-vacuum formed as a preliminary operation or in place in the paperboard tray or carton in contact with the plastic or paper coating thereon and this plastic line may be so preformed into place as to be separable therefrom and to provide with the lid to which it is heat sealed a separable container. This container may be vacuumized so that the plastic bag attached to the lid shrinks about the product therein to provide for minimizing of oxygenation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
154 words
A carton corner construction comprising a bottom wall, a pair of side walls disposed normal to each other and to said bottom wall, a flange on each side wall normal thereto, one side wall and its flange having coincident edges, the other side wall and its flange having offset edges whereby a portion of said lastmentioned flange projects beyond the edge of said other side wall, a gusset hinged by first and second fold lines to said one and other side walls respectively, a third fold line dividing said gusset into a pair of gusset panels folded along said third fold line against one another and against one of said side walls, a flange hinged by a fourth fold line to one of said gusset panels, a tab projecting from said flange portion normal thereto and in the same plane thereof, and said tab being in overlapped relationship to said one side wall flange.
Claim 2
Dependent Claim
154 words
A carton corner construction comprising a bottom wall, a pair of side walls disposed normal to each other and to said bottom wall, a flange on each side wall normal thereto, one side wall and its flange having coincident edges, the other side wall and its flange having offset edges whereby a portion of said lastmentioned flange projects beyond the edge of said other side wall, a gusset hinged by first and second fold lines to said one and other side walls respectively, a third fold line dividing said gusset into a pair of gusset panels folded along said third fold line against one another and against one of said side walls, a flange hinged by a fourth fold line to one of said gusset panels, a tab projecting from said flange portion normal thereto and in the same plane thereof, and said tab being in overlapped relationship to said one side wall flange.
Claim 3
Dependent Claim
24 words
The carton corner construction as defined in claim 1 wherein said tab is sandwiched between said one side wall flange and said gusset flange.
Claim 4
Dependent Claim
24 words
The carton corner construction as defined in claim 1 wherein said tab is formed by material robbed from the other of said gusset panels.
Claim 5
Dependent Claim
24 words
The carton corner construction as defined in claim 2 wherein said tab is formed by material robbed from the other of said gusset panels.
Claim 6
Dependent Claim
218 words
A carton corner construction comprising a bottom wall, a pair of side walls disposed normal to each other and to said bottom wall, a flange on each side wall normal thereto, one side wall and its flange having coincident edges, the other side wall and its flange having offset edges whereby a portion of said last-mentioned flange projects beyond the edge of said other side wall, a gusset hinged by first and second fold lines to said one and other side walls respectively, a third fold line medially of fourth and fifth fold lines dividing said gusset into first through fourth gusset panels folded along said first through fifth fold lines to bring two of said guesset panels against each other and against said one side wall and the remaining two of said gusset panels against each other and against said other side wall, a flange hinged by sixth and seventh fold lines to each of the centermost two of said four gusset panels, a tab projecting from said flange portion normal thereto and in the same plane thereof, one each of said centermost gusset panel flanges being folded about the respective sixth and seventh fold lines against said one and other side walls respectively, and said tab being in overlapped relationship to said one side wall flange.
Claim 7
Dependent Claim
218 words
A carton corner construction comprising a bottom wall, a pair of side walls disposed normal to each other and to said bottom wall, a flange on each side wall normal thereto, one side wall and its flange having coincident edges, the other side wall and its flange having offset edges whereby a portion of said last-mentioned flange projects beyond the edge of said other side wall, a gusset hinged by first and second fold lines to said one and other side walls respectively, a third fold line medially of fourth and fifth fold lines dividing said gusset into first through fourth gusset panels folded along said first through fifth fold lines to bring two of said guesset panels against each other and against said one side wall and the remaining two of said gusset panels against each other and against said other side wall, a flange hinged by sixth and seventh fold lines to each of the centermost two of said four gusset panels, a tab projecting from said flange portion normal thereto and in the same plane thereof, one each of said centermost gusset panel flanges being folded about the respective sixth and seventh fold lines against said one and other side walls respectively, and said tab being in overlapped relationship to said one side wall flange.
Claim 8
Dependent Claim
