Abstract

A single blank of sheet material is configured to be formed into a folding carton having a bottom panel, mutually opposed side panels, and mutually opposed end panels, with front and back top panels that are arranged to be closed over a top opening of the folding carton to close the top opening of the carton and form a carrying handle for the carton. The folding carton is assembled solely from the single blank of sheet material without the use of glue or adhesives or any other manner of securing one carton component to another that is separate from the single blank of sheet material.
