摘要： The present invention relates to dispensing cartons for sheet materials such as polymeric sheets, metallic foils, and other sheet materials, particularly those suitable for use in the containment and protection of various items including perishable materials. The present invention further relates to such cartons which permit end-loading of the roll of product into the carton during the manufacturing process. The present invention provides an asymmetrical carton for containing and dispensing a roll of sheet material. The carton has a longitudinal axis, and has both an erected condition and a flattened condition. The carton when erected forms a cylindrical structure having an asymmetrical polygonal cross-section formed from a plurality of substantially planar side panels. The carton has fold lines defined by the intersection of adjacent side panels, and is foldable into a flattened condition by folding the carton at two fold lines to form a substantially planar structure.
