A packet serving to contain a group of cigarettes appears substantially parallelepiped in shape with a predominating longitudinal axis disposed parallel to the longitudinal axes of the cigarettes, and comprises a front, a back and two flanks, also a bottom, and a top that can be opened at least in part to provide an area affording access to the inside of the packet. The cigarettes are packaged together with a fan-folded pressure element of stiff paper placed between the group and one flank, which is rendered flexible along at least one line or portion of elastic deformation and able thus to compress and expand elastically along an axis of compression and expansion normal to the axis of the packet; as a result of the tension stored in the pressure element, the cigarettes are invested with a uniformly applied pushing force and biased toward the access area whilst a similarly uniform reaction force is directed against the inside face of the flank.
A packet for a group of articles of elongated shape, substantially parallelepiped in appearance with a predominating longitudinal axis disposed parallel to the longitudinal axes of the articles, comprising a front, a back, two flanks, a bottom and a top, of which at least the top is removable at least in part providing an opening that coincides with an area affording access to the inside of the packet, and tension means disposed internally of the packet and generating a pushing force on the group causing the group to shift toward the access area, said tension means being deformable elastically along at least one predetermined line or portion of elastic deformation, said tension means comprising an elastically deformable pressure element having an axis of compression and expansion and having a rippled profile including a succession of alternating ridges and troughs joined together and elastically deformable along respective lines of elastic deformation, said lines of elastic deformation extending substantially parallel to the longitudinal axes of the articles of elongated shape.
A method of manufacturing a packet for groups of articles of elongated shape, said packet appearing substantially parallelepiped in shape with a predominating longitudinal axis disposed parallel to the longitudinal axes of the articles, presenting a front, a back, two flanks, a bottom and a top, of which at least the top is removable at least in part to provide an opening that coincides with an area affording access to the inside of the packet,
A method as in claim 16, wherein associating each group of articles with tension means includes positioning the tension means relative to the group, such that said tension means is compressible and expandable along an axis of compression and expansion extending substantially perpendicular to the predominating longitudinal axis of the packet and substantially parallel to the front and the back.
