Abstract

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.

Dependent claims

Tubular carton movable between a collapsed condition and an erect condition in the shape of a parallelepiped, comprising, in combination:

a front panel having first and second side edges;
a first side panel having first and second side edges, with the second side edge of the front panel and the first side panel abutting at all points and being integrally connected together about a fold line, with the front panel overlying the first side panel in the collapsed condition;
a back panel having first and second side edges, with the first side edges of the back panel and the first side panel abutting at all points and being integrally connected together about a fold line, with the back panel and the first side panel being planar in the collapsed condition;
a second side panel having first and second side edges, with the second side edges of the back panel and the second side panel abutting at all points and being integrally connected together about a fold line, with the back panel underlying the second side panel in the collapsed condition, with the first side edges of the front panel and the second side panel abutting at all points and being continuously integrally connected together about a fold line, with the front and second side panels being planar in the collapsed condition, with at least the front panel and the second side panel having top and bottom edges, with the fold line between the front and second side panels extending in a non-linear manner between the top and bottom edges of the front panel and the second side panel, with the side panels extending generally perpendicular between the front and back panels in the erect condition.
