ABSTRACT:
A carton includes a longitudinally extending sidewall portion which circumscribes and defines a carton cross-section interior and is provided with at least two tiers of integral support ledges which extend into the carton interior. Each support ledge is formed from a pair of slits in the sidewall which extend integrally from and between spot creases formed in the sidewall, and each support ledge has at least two interior spot creases positioned between the end spot creases. The carton may have a rectilinear cross-section and longitudinally extending corner edges formed by adjacent sidewalls, and the slits which form the support ledge may be offset with respect to the corner edge formed by the adjacent sidewalls from and between which the slits extend.
