Folding carton with interior struts

A folding carton having an exterior rectangular cross section for packaging a member having a nonrectangular cross section comprising, in combination,

• a front panel, side panels, and a rear panel,
• a strut panel extending from one of said panels,
• an extension strut formed in said strut panel and having an extension strut score,
• a reverse strut formed in said strut panel and having a reverse strut score parallel to and spaced from the extension strut score,
• a glue flap portion adjacent the junction of the strut panel and the panel from which it extends,
• said extension and reverse struts being above and below each other,
• said glue flap portion being secured to the marginal edge of the panel remote from the strut panel to form a tubular folding carton with front, side and rear panels,
• top closure means extending from the upper portion of ones of said panels,
• bottom forming means extending from the lower portion of said panels and secured to each other to form a bottom when the carton is erected,
• said extension and reverse strut being formed to extend from and reversely fold from said strut panel when the carton is erected to have an angular relationship each with the other and having their ends contact ones of said panels, whereby an interior nest is provided by the struts in the carton when erected to receive a non-rectangular cross sectioned member and nestingly engage the same against rotation.
