Right parallelepiped package including non-linear fold line

A collapsible, tubular carton (12) is disclosed having a non-linear fold line between the side edges (20) of the front panel (18) and the second side panel (32) which are planar in the collapsed condition of the carton (12). The fold line extends in a non-linear manner between top and bottom locations (72, 74) at the top edges (48, 68) and the bottom edges (40, 44) of the front and side panels (18, 32). In the preferred form, the fold line includes first and second, arcuate portions (82, 84) in the form of a sine curve extending from and on opposite sides of a linear line (76) extending between the top and bottom locations (72, 74). In its erect condition in the most preferred form, the carton (12) has a right parallelepiped shape, with the front and second side panels (18, 32) forming two of the sides of the parallelepiped shape. In the erect condition, the fold line between the front and second side panels (18, 32) creates a rippled corner having a tendency to attract the consumer's attention because of the difference in shape of the package (10) created thereby.
