ABSTRACT:
Cartons for packaging and mailing books and the like include parallel major and minor walls which are foldably interconnected to form a tubular structure and a closure and protecting structure for each end of the tubular structure including end flaps which are folded to form triangularly shaped air cushions, and, in a modification, a trapezoidally shaped air cushion. The end flaps are provided with locking tabs which engage corresponding notches in the top surface of one of the major walls in order to form the air cushions.
