Carton with multi-ply folds
First Claim
1. In a carton comprised at least in part of a flexible sheet incorporating a panel having opposite edges defined by spaced substantially parallel folds, each fold extending at an acute angle with respect to adjacent portions of the sheet, the improvement comprising:
- the panel and adjacent portions of the sheet being of multi-ply construction, including an inner ply and a second ply adjacent thereto;
the folds of the panel being defined in each of the plies by score lines;
the score lines of the folds in the inner ply being spaced apart a distance greater than the score lines of the folds in the second ply.

Abstract
A carton including a bevel panel and adjacent areas comprised of multi-ply construction. The bevel panel of each ply is defined in part by spaced score lines. The score lines of each ply are spaced apart a distance greater than the spacing of the score lines of the next outer ply. This results in the plies of the bevel panel being slightly spaced from each other. An example of such bevel panels is in the type of container formed by wrapping a slotted flexible sheet about rigid end panels having corner areas which extend through the slots.

8. A container, comprising:
-
two spaced, substantially parallel, relatively rigid end panels; a flexible sheet attached to and extending between the end panels to form panels of the container; the container including at least one bevel panel having opposite edges defined by spaced substantially parallel folds, each fold extending at an acute angle with respect to adjacent portions of the flexible sheet; the bevel panel and the adjacent portions of the sheet being of multi-ply construction, including an inner ply and a second ply adjacent thereto; the folds of the bevel panel being defined in each of the plies by score lines; the score lines of the bevel panel folds in the inner ply being spaced apart a distance greater than the score lines of the bevel panel folds in the second ply. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A carton blank, comprising:
-
a flexible sheet at least a portion of which is of multi-ply construction; the sheet incorporating a bevel panel section in the multi-ply portion thereof defined by spaced substantially parallel score lines; one of the plies of the bevel panel section forming the inner ply in a carton formed from the blank and the ply next adjacent thereto forming a second ply of such a carton; the score lines of said one ply of the bevel panel section being spaced apart a distance greater than the score lines of the next adjacent ply. - View Dependent Claims (17, 18)

19. A method of forming a bevel panel in a carton comprised at least in part of a flexible sheet of multi-ply construction, comprising:
-
forming a first pair of spaced score lines in the sheet to define a bevel panel section in an inner ply of the carton; forming a second pair of spaced score lines in the sheet to define a bevel panel section in the next adjacent ply of the carton; the first pair of score lines being spaced apart a greater distance than the second pair of score lines;
folding the sheet about a fold line located between the first and second pairs of score lines so that the score lines of the second pair are inwardly offset from the score lines of the first pair;adhering the folded portions of the sheet together without adhering the bevel panel sections to each other; and forming the bevel panel by inwardly folding the multi-ply sheet about the first pair of spaced score lines. - View Dependent Claims (20)
