Abstract

A collapsible carton of the type composed of a series of hinged-together panels folded spirally to form a double-walled tube has spacers at all four corners of the carton which extend between the corresponding inner and outer walls to maintain their spaced-apart relationships. A divider, preferably also double-walled, extends between opposite inner walls of the carton dividing the carton interior into two compartments.
