Abstract
A shape-stable packing carton with an octagonal cross-section has an interior working space with a rectangular cross-section for the accommodation of a bundle of cigarette packets or other rectangular objects and side portions at both sides of the working space with a cross-section forming an equilateral trapezoid with a base line directed along the side wall of the working space. The shape stability of the packing carton is ensured by reinforcing inserts of the same material fixed in the side portions thereof. Each insert consists of a blank in which a surface corresponding to the side wall of the working space is formed, by folding and gluing, with a parallel pair of channels, running in the longitudinal direction of the packing carton, with a rectilinear cross-section. The channels are formed by defined pressing-together of the rectangular end portions forming the channels into rhombi which are inclined towards one another in such a way that the cross-section of the thus-formed insert conforms to the cross-section of the side portions. The inserts are glued in this state to the side walls of the packing carton.
