1. A carton comprising: a front panel, a back panel, a first side panel, and a second side panel, all of the panels each having a top edge, a bottom edge, and first and second side edges; a front upper flap and a back upper flap, each having a top edge, a bottom edge, and two opposing unconnected side edges, the bottom edge of the front upper flap and the top edge of the front panel being connected about a first fold line, the bottom edge of the back upper flap and the top edge of the back panel being connected about a second fold line; and a front lower flap and a back lower flap, each having a top edge, a bottom edge, and two opposing side edges, the top edge of the front lower flap and the bottom edge of the front panel being connected about a third fold line, the top edge of the back lower flap and the bottom edge of the back panel being connected about a fourth fold line; wherein at least a portion of the third fold line between the top edge of the front lower flap and the bottom edge of the front panel is arcuate, wherein when the front lower flap and front panel are folded with respect to each other, the arcuate portion of the third fold line imparts tension on the front panel; and wherein at least a portion of each of the front panel and the front upper flap include a fifth fold line that extends in a direction transverse to the third fold line, wherein, when the front upper flap is extended relative to the front panel, the front panel and the front upper flap are bowed at the fifth fold line due to the tension imparted by the arcuate third fold line on the front panel when the front lower flap and front panel are folded with respect to each other.
