Decorative carton closure

In an automatic end closure arrangement for a collapsible, decorative carton formed from a unitary blank of foldable paperboard, the combination of:

• a. opposed first and second pairs of side walls hingedly interconnected on parallel score lines to form a tubular structure open at one end;
• b. opposed first and second pairs of closure flaps hingedly attached to related end edges of said first and second pairs of side walls, respectively;
• c. each of said closure flaps including a major section, hingedly attached at one edge thereof to a related side wall on a hinge line extending in a direction normal to said score lines, and a minor section, hingedly attached to another edge of said major section along a fold line extending at an angle of less than 90.degree. with respect to said score and hinge lines;
• d. each of said closure flaps having one of said sections presenting a free outer edge extending generally parallel to said hinge line and having the other of said sections presenting an extension projecting beyond said free edge of said one section;
• e. said first pair of closure flaps having said extensions on their respective major sections, and said second pair of closure flaps having said extensions on their respective minor sections;
• f. said minor sections of said first pair of closure flaps being folded 180.degree. on said fold lines and being secured in face-to-face relation with their respective major sections to prevent the exposure of raw edges of said closure flaps from the outside of said carton;
• g. said extensions on each of said first pair of closure flaps being secured in face-to-face relation with respective extensions on said second pair of closure flaps, so that when the carton is moved from a collapsed condition to an erected condition, all of said closure flaps will automatically be folded sequentially into overlapped relationship to close said one end of said tubular structure.
