Abstract

A carton (10, 210) having a primary elevated bottom portion (20, 220) extending along the length of an exposed raw paperboard edge (40, 240) to protect the carton (10, 210) and to prevent moisture absorption. The carton (10, 210) may also have a secondary elevated bottom portion (100, 300) substantially within the primary elevated portion (20, 220) and have an elevation greater than the primary elevated bottom portion (20, 220). Additional elevated portions (20a, 220a) are provided for additional raw paperboard edges (40b, 240b) on the bottom of the carton (10, 210). The present invention alleviates the problem of cartons (10, 210) having soggy bottoms since the point of absorption, the raw paperboard edge (40, 240), is elevated above the moisture which may be present during distribution from the packaging machine to the retailer. The elevated bottom portion (20, 220) is actually inverted into the carton (10, 210) with planar portions (60, 260 and 62, 262) resting on the surface to support the carton (10, 210).
