blank made of a wrapping material for making a rigid package with hinged lid for an ordered group of cigarette packs and the relative packing method

摘要

A rigid package with hinged lid which holds a group of cigarette packs stacked flat against one another, parallel with the bottom of the package, along a stacking axis which is at a right angle to the longitudinal axes of the packs comprises a container and a lid, which are hinged together, and an inner frame which is partially inside the container; the package is made from a flat blank which is substantially rectangular and, in the direction of its longer longitudinal axis has a main portion designed to define the container and the lid, and a longitudinal end appendix designed to be folded over the main portion to define the inner frame; the appendix is substantially U-shaped and is hinged, with its arms, to two side panels of the blank which define the sides of the package and surrounds a longitudinal free end of the main portion; the free end consists of a panel designed to define the bottom of the package, and two side tabs and a longitudinal end tab defining respective flaps for closing the bottom; the group is fed at a right angle to its stacking axis and the axes of the packs towards a folding unit, to which the blank is fed parallel with its longitudinal axis and with the stacking axis, and which folds the blank around the group, by folding it about an axis at a right angle to both the stacking axis and the longitudinal axis.
