  • FIG. 1 shows an example rigid pack 1 , made from a board material such as paperboard or cardboard, with a hinged lid 2 and a base 3 containing a group of cigarettes 4 wrapped in a barrier material 5 to form a bundle 6 .
  • An extraction opening 7 is formed in the barrier material 5 .
  • the extraction opening 7 is formed when a separable section 8 of the barrier material 5 is lifted to allow access to the cigarettes 4 .
  • the barrier material 5 may be made of metallized plastics or of a plastics/metal foil laminate material.
  • a label 9 extends over and is attached to the section 8 and has, on its undersurface facing the barrier material 5 , a pressure sensitive re-stick adhesive which is of sufficient strength to ensure that the label 9 remains adhered to the section 8 .
  • a permanent bonding adhesive may be applied to the portion of the undersurface of the label 9 which overlies the removable section 8 .
  • the label 9 extends beyond the removable section 8 , its undersurface is provided with re-stick adhesive.
  • an inner frame (not shown) may be provided within the bundle 6 so that it extends partially around the cigarettes 4 beneath the barrier material 5 .
  • the inner frame provides a reaction surface underneath the barrier material 5 against the resealing pressure exerted by the label 9 around the periphery of the extraction opening 7 .
  • a region 10 (see FIG. 2 ) of a lower front wall edge of the label 9 which may include a tab, is attached to the front wall ii of the lid 2 so that the label 9 is peeled back to reveal the extraction opening 7 at the same time the lid 2 is opened.
  • section 8 of the barrier material 5 is drawn back to reveal the extraction opening 7 and to enable a consumer to readily extract a cigarette 4 from the bundle 6 .
  • section 8 may be removable, it will be appreciated that it may remain at least partially attached to the remainder of the barrier material 5 when the extraction opening 7 is revealed.
  • a portion of the outer surface 12 of the label 9 is attached to the lid 2 using permanent adhesive so that it folds back relative to the remainder of the label 9 when the lid 2 is rotated into an open position (as most clearly seen in FIG. 2 ).
  • the label 9 is peeled back or rolled away from the barrier material 5 together with the removable section 8 . If the pack 1 is being opened for the first time, the removable region 8 may also separate from the remainder of the barrier material 5 along a line of weakening that separates the removable region 8 from the remainder of the barrier material 5 , as the lid 2 is opened.
  • the label 9 will roll back across the barrier material 5 and the removable region 8 of the barrier material 5 will re-position itself within the extraction opening 7 .
  • the peelable adhesive coating a peripheral region 14 of the label 9 will re-adhere to the barrier material 4 surrounding the extraction opening 6 to reseal the pack 1 .
  • the lid 2 comprises a front wall 14 and a lid front wall flap 15 which is folded relative to the front wall 14 substantially 180 degrees about a fold line ‘F’ between the lid front wall 14 and the lid front wall flap 15 so that a rear face 16 of the lid front wall flap 15 lies against an inner face 17 of the lid front wall 14 , leaving a front face 18 of the lid front wall flap 15 exposed.
  • the rear face 16 of the lid front wall flap 15 may be permanently adhered to the inner surface 17 of the lid front wall 14 .
  • print may be applied to an outer surface 19 of the lid front wall 14 and around the fold line F onto the front face 18 of the lid front wall flap 15 .
  • the outer surface of the label 9 is adhered to the front face 18 of the lid front wall flap 15 .
  • the sheet of board material from which the lid and base are formed can have a metallised, or otherwise coated, external surface layer.
  • This surface is the external surface visible to a consumer.
  • the board material may be Transmet board, which is a film-free metallic laminate for paperboard that provides a print receptive coating to the base material in a bright metallic finish. Transmet laminate is manufactured by the API Group.
  • the board material may be Metpol, which has a layer of metallisation coated with a polymer layer.
  • the front face 18 of the lid front wall flap 15 to which the label 9 is adhered has the metallised, or otherwise coated, surface.
  • This surface or coating has a low affinity or receptivity to adhesive, as the adhesive is unable to penetrate the material, or penetrate it sufficiently, to form a good bond.
  • Both Transmet and Metpol boards suffer from this problem, as the external surface layer is non-porous and so does not readily absorb adhesive.
  • the front face 18 of the lid front wall flap 15 is non-mechanically treated to increase its receptivity or affinity to adhesive thereby improving the bond between the lid front wall flap 15 and the label 9 .
  • the non-mechanical treatment of the lid front wall flap 15 removes all, or some, of the surface layer or coating, to thereby expose the underlying board which has a much greater affinity for adhesive.
  • the label 9 is therefore adhered to treated surface. It will be appreciated that the non-mechanical treatment may be carried out on all of the front face of the lid front wall flap. Alternatively it may be carried out on portions of it.
  • Treatment may be carried out using a laser, such as a CO 2 laser.
  • the laser 20 may have a power rating of 100 Watts and be operated within a range of 50% to 90% of its power to remove the surface layer or coating whilst causing little or no damage to the underlying board.
  • FIG. 4 The use of a laser is shown in FIG. 4 , in which a laser treatment unit 20 is shown, that emits a laser beam ‘L’ towards the front face 18 of the lid front wall flap 15 .
  • the laser may move.
  • the laser 20 may move as indicated by arrows marked ‘X’ and ‘Y’ in FIG. 4 .
  • the laser treatment unit may remain stationary and the lid front wall flap 15 may pass beneath it.
  • the laser treatment unit 20 may be active for a short period of time sufficient to treat the lid front wall flap 15 .
  • the laser treatment unit 20 may be operational for a period of time in the region of 0.5 seconds.
  • the lid front wall flap 15 may be treated to remove a portion of the surface using a chemical or by using plasma.
  • treatment occurs after the lid front wall flap has been folded against the inner surface 17 of the lid front wall 14 by a folding unit 21 , and prior to the application of adhesive in an adhering unit 22 that applies adhesive to the treated front face 18 of the lid front wall flap 15 and sticks the label 9 to the front face 18 .
  • the treatment may occur at any time or stage in the manufacturing or packaging process.
  • the non-mechanical treatment may be carried out prior to folding the lid front wall flap 15 .
  • lid front wall flap 15 may be treated, or the whole of the flap may be treated.
  • the part of the lid front wall flap 15 which is treated may be treated such that all or only part of a surface layer or coating is removed.
  • treatment occurs in a packaging machine, during assembly of the pack after the folding unit 21 has folded the lid front wall flap 15 against the inner is surface 17 of the lid front wall 14 but prior to any further folding of the sheet.
  • Folding of the lid front wall flap 15 against the inner surface 17 of the lid front wall 14 is illustrated in FIG. 3 , and shows the lid front wall flap 15 being rotated, about the fold line F extending along a lower edge of the lid front wall 14 , in the direction of arrow ‘A’.
  • the invention is primarily intended for removing a surface coating or layer from board material, it will be understood that the invention is also applicable to board that does not have a surface layer or coating, in order to remove any loose material or oxides and expose a fresh surface which will be more receptive to bonding.
  • the label 9 which has a portion attached to the front face 18 of the lid front wall flap 15 , may be a separate element that is applied to the wrapped bundle 6 .
  • the barrier material 5 may be a laminate material.
  • the label 9 may be integrally formed from the barrier material 5 and comprise one or more layers of the laminate.
