Quickly erected scoop-type carton and layout for cutting
First Claim
1. A blank for forming a carton comprisinga bottom panel,a pair of sidewall panels each connected to said bottom panel on opposite sides of said bottom panel,end wall panels attached on opposite sides of one of said sidewall panels,glue flaps attached to each of said end wall panels along opposite edges of said end wall panels from the edges of said end wall panels attached to said sidewall panels,a portion of the outer edge of each of said glue flaps aligned parallel to a center line extending longitudinally through said bottom and sidewall panels,a second portion of the outer edge of each of said glue flaps extending inward at an acute angle from said parallel edge portion,the other one of said pair of sidewall panels having an edge portion on each side parallel to the center line extending longitudinally through said bottom and sidewall panels, and outwardly extending edge portions on each side of said sidewall panel extending at an obtuse angle from each of said parallel sidewall edge portions which obtuse angle is complementary to said acute angle of each of said second portions of the outer edges of said glue flaps.

Abstract
An improved blank for a scoop-type carton with a layout and method for the cutting of quickly erected scoop-type cartons with a maximum of nested common edges and the remaining edges at a distance exceeding the widths of two cutting knife blades. This is partially obtained by increased use of common edges parallel to the carton center line and the areas on the flaps for gluing.

1. A blank for forming a carton comprising
a bottom panel, a pair of sidewall panels each connected to said bottom panel on opposite sides of said bottom panel, end wall panels attached on opposite sides of one of said sidewall panels, glue flaps attached to each of said end wall panels along opposite edges of said end wall panels from the edges of said end wall panels attached to said sidewall panels, a portion of the outer edge of each of said glue flaps aligned parallel to a center line extending longitudinally through said bottom and sidewall panels, a second portion of the outer edge of each of said glue flaps extending inward at an acute angle from said parallel edge portion, the other one of said pair of sidewall panels having an edge portion on each side parallel to the center line extending longitudinally through said bottom and sidewall panels, and outwardly extending edge portions on each side of said sidewall panel extending at an obtuse angle from each of said parallel sidewall edge portions which obtuse angle is complementary to said acute angle of each of said second portions of the outer edges of said glue flaps.

5. A layout for the knife blade cutting of a plurality of interfitting carton blanks into sheets of several carton blanks and the cutting into individual carton blanks, with each of the carton blanks having a center line running substantially longitudinally of the carton blank comprising
edge portions of the carton blanks extending parallel to said center lines, complementary edge portions also parallel to said center lines and complementarily interfitting with said first mentioned parallel edge portion, the sum of the distance from the center line to an edge portion and the center line and an adjacent complementary edge portion being equal to the distance between center lines of adjacent carton blanks on the layout, edge portions sloping inward toward the center line of the cartons from said first mentioned parallel edge portions, complementary edge portions sloping outward from the center line of the cartons from said complementary parallel edge portions at an angle complementary to the angle of the inward slope of said inward sloping edge portions, a plurality of carton blanks comprising the layout, each of said carton blanks including a bottom panel, a pair of sidewall panels each connected to said bottom panel on opposite sides of said bottom panel, end wall panels attached on opposite sides of one of said sidewall panels, glue flaps attached to each of said end wall panels along opposite edges of said end wall panels from the edges of said end wall panels attached to said sidewall panels, a portion of the outer edge of each of said glue flaps aligned parallel to a center line extending longitudinally through said bottom and sidewall panels, a second portion of the outer edge of each of said glue flaps extending inward at an acute angle from said parallel edge portion, the other one of said pair of sidewall panels having an edge portion on each side parallel to the center line extending longitudinally through said bottom and sidewall panels, and outwardly extending edge portions on each side of said sidewall panel extending at an obtuse angle from each of said parallel sidewall edge portions which obtuse angle is complementary to said acute angle of each of said second portions of the outer edges of said glue flaps, said first mentioned parallel edge portions and said inward sloping edge portions being said parallel outer edge portions of said glue flaps and said inward extending second portions of the outer edges of said glue flaps respectively, said complementary parallel edge portions and said complementary outward sloping edge portions being said parallel edge portions of said sidewall panels and said outwardly extending edge portions of said sidewall panels respectively.
