RIGID PACKET OF CIGARETTES

Abstract: A rigid packet (1) of cigarettes, wherein an outer wrapping (2) of multilayer cardboard encloses a group (3) of cigarettes wrapped in an inner wrapping (4), and wherein a portion (21) of magnetic material is located within the thickness of a wall of the outer casing (2).

Description: RIGID PACKET OF CIGARETTES TECHNICAL FIELD The present invention relates to a rigid packet of cigarettes. BACKGROUND ART Known rigid packets are normally parallelepiped- shaped and comprise an inner wrapping of foil or paper wrapped about a group of cigarettes; and an outer wrapping in turn comprising a parallelepiped-shaped box normally formed from a blank with preformed bend lines, and a collar interposed between the box and the inner wrapping . Packets of the above type are known, from Patent EP 317202, to be provided with respective magnetic tapes or media visible from the outside and for recording data unequivocally identifying the respective packets. In other words, the magnetic tape, or medium in general, constitutes, for the respective packet, a certificate of origin making counterfeiting of the packet extremely complicated and expensive. One of the drawbacks of packets of the above type lies in the magnetic tape or medium being visible from the outside. That is to say, while not being made easier to counterfeit, the fact that the magnetic media are visible from the outside inevitably results in a relaxation of security measures, in the sense that distributors or retailers eventually simply check to determine the presence of the magnetic medium, as opposed to the data recorded on it . DISCLOSURE OF INVENTION It is an object of the present invention to provide a packet of cigarettes having a data recording element with magnetic properties, and wherein said element with magnetic properties is not only invisible from the outside, but is also located in a precise, unalterable position on the packet. According to the present invention, there is provided a rigid packet of cigarettes, comprising at least one outer wrapping about a group of cigarettes, and at least one means with magnetic properties; characterized in that said outer wrapping is made of multilayer cardboard of a given thickness; and said means with magnetic properties is located in a fixed position within the thickness of a wall of said outer wrapping. BRIEF DESCRIPTION OF THE DRAWINGS A number of non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying drawings, in which: Figure 1 shows a view in perspective of a preferred embodiment of the packet according to the present in the open position; Figure 2 shows a section along line II- II in Figure l; Figure 3 shows a layout of a blank from which to form the Figure 1 packet, and showing a detail of Figures 1 and 2 in various alternative positions. BEST MODE FOR CARRYING OUT THE INVENTION Number 1 in Figure 1 indicates as a whole a packet of cigarettes comprising a substantially rigid outer wrapping 2 housing a group 3 of cigarettes enclosed in a foil inner wrapping 4. Outer wrapping 2 comprises a box 5 formed by folding in known manner an originally flat blank 6, which may be made of multilayer cardboard or similar of a given thickness. Box 5 in turn comprises a bottom cup-shaped container 7; and a cup-shaped lid 8 hinged to container 7 along a hinge line 9 to rotate, with respect to container 7, between a closed position (not shown) and an open position as shown in Figure 1. Box 5 is substantially in the form of a right parallelepiped, and comprises two major lateral walls 10 and 11; wall 10 being located at the front and defining a front wall 10a of container 7 and a front wall 10b of lid 8; and wall 11 being located at the rear and defining a rear wall 11a of container 7 and a rear wall lib of lid 8. Box 5 also comprises two minor lateral walls 12 and 13, each defining a respective lateral wall 12a, 13a of container 7 and a respective lateral wall 12b, 13b of lid 8. Finally, box 5 also comprises a bottom wall 14 and a top wall 15 forming part of container 7 and lid 8 respectively. Outer wrapping 2 also comprises a collar 16, which may be made of multilayer cardboard and is located between box 5 and inner wrapping 4 so that a portion 17 of the collar projects from container 7 and, when lid 8 is closed, is housed inside lid 8. Collar 16 comprises a front wall 18 parallel to, and directly contacting the inner surface of, front major lateral 10 of box 5; and two lateral walls 19 and 20 parallel to, and directly contacting the inner surface of, minor lateral walls 12 and 13 of box 5. Packet 1 comprises a portion 21 of magnetic data recording material, which, as shown more clearly in Figure 2, is located in a fixed position between two layers 22 of blank 6 or of collar 16. Portion 21 of magnetic material may be applied, as described later on, in any position on blank 6 or collar 16, but is preferably located, as shown in Figure 1, a sufficient distance from bottom wall 14, top wall 15 and minor lateral walls 12 and 13, which walls 14, 15, 12 and 13 may undergo, during the application of an overwrapping (not shown) , to operations involving a considerable increase in temperature which could damage portion 21. Blank 6 (Figure 3) - the parts of which are indicated, wherever possible, using the same reference numbers, with superscripts, as for the corresponding walls of box 5 - extends substantially longitudinally along a longitudinal axis 23 of symmetry, and comprises a number of preformed transverse bend lines 24, i.e. perpendicular to longitudinal axis 23, and two preformed longitudinal bend lines 25, i.e. parallel to and on either side of longitudinal axis 23, along which blank 6 is folded to form box 5. Longitudinal bend lines 25 divide blank 6 into a central portion 26, and into two lateral portions 27 on either side of central portion 26. Along central portion 26, blank 6 comprises an end tab 28, which, when forming box 5, is folded inside front wall 10b of lid 8. Along each lateral portion 27, blank 6 comprises four tabs 29-32, which, when forming box 5, are superimposed - tab 29 on tab 30, and tab 32 on tab 31 - to form a respective minor lateral wall 12, 13 of box 5. In the first embodiment of the invention described above, portion 21 of magnetic material is applied, off the machine, between layers 22 of blank 6 or collar 16, whereas, in a variation shown in Figure 3, portion 21 of magnetic material is applied, on the machine, to one of tabs 30 or 31 of blank 6 - preferably at the minor lateral wall 12 or 13 unaffected by heat sealing of the overwrapping (not shown) - so as to be embedded in the thickness of one of the walls of the finished box 5. In a further variation shown in Figure 3, portion 21 of magnetic material is applied, on the machine, to tab 28 or to the inner face of wall 10b', so as to be located between tab 28 and wall 10b when forming box 5, and therefore inside the thickness of front wall 10b of lid 8 of the finished box 5.
