Abstract
A gable top carton and its corresponding carton blank are disclosed. The carton includes two indent surfaces near the gable top that are defined by a score line configuration that facilitates controlled deformation of the gabled top to increase the roof angle of the top so as to limit the risk of rolling.
Claims32
A gable top carton comprising:
- a gabled structure having an opening end, a fin, and first and second oppositely angled roof portions extending from and engaging the fin, the first and second oppositely angled roof portions forming spout flaps at the opening end, the spout flaps being adapted for folding back along a predefined score line configuration during opening of the carton;
- a plurality of side panels engaging said gabled structure, including first and second opposite side panels respectively engaging the first and second oppositely angled roof portions;
- a first score line defining a crease formed at the engagement between the first side panel and the first angled roof portion;
- a second score line defining a crease formed at the engagement between the second side panel and the second angled roof portions;
- a first complementary score line on the first side panel disposed adjacent the first score line and defining a first indent surface between the first score line and the first complementary score line;
- and
- second complementary score line on the second side panel disposed adjacent the second score line and defining a second indent surface between the second score line and the second complementary score line.

A blank for forming a gable top carton comprising:
- first, second, third, and fourth side panels, the side panels divided from one another by a plurality of vertical score lines;
- first, second, third, and fourth top flaps respectively adjacent the first, second, third, and fourth side panels, wherein the first and third top flaps respectively form first and second oppositely angled roof portions of the gable top when the blank is folded to form the carton;
- first, second, third, and fourth score lines formed at the engagement between the first, second, third, and fourth side panels and the first, second, third, and fourth top flaps;
- a first complementary score line on the first side panel disposed adjacent the first score line and defining a first indent surface between the first score line and the first complementary score line when the blank is folded to form the carton;
- and
- a second complementary score fine on the third side panel disposed adjacent the third score line and defining a second indent surface between the third score line and the second complementary score line when the blank is folded to form the carton.
