Definitions

  • the present invention relates to a package of tobacco articles comprising a sealed inner package .
  • the present invention may be applied to advantage to a rigid packet of cigarettes, to which the following description refers purely by way of example.
  • Rigid, hinged-lid packets of cigarettes are currently the most widely marketed, by being easy to produce and easy and practical to use, and by effectively protecting the cigarettes inside.
  • a rigid, hinged-lid packet of cigarettes comprises an inner package comprising a foil-wrapped group of cigarettes; and a rigid outer container housing the inner package .
  • the outer container comprises a cup- shaped container housing the group of cigarettes and having an open top end; and a cup- shaped lid hinged to the container to rotate, with respect to the container, between an open position and a closed position opening and closing the open end respectively.
  • a sealed (i.e. airtight) inner package comprising a cigarette extraction opening closed by an open-close sealing flap (the sealing flap is applied with non-dry, re -stick glue enabling it to be stuck repeatedly in the closed position closing the cigarette extraction opening) .
  • Patent US6237760A1 and Patent Application DE102009060134A1 describe two examples of a sealed inner package containing a group of cigarettes and having a cigarette extraction opening closed by an open-close sealing flap.
  • the grou of cigarettes , inside the sealed inner package is enclosed in a stiffener inserted inside the sealed inner package, directly contacting the cigarettes, and which comprises a front wall contacting the cylindrical lateral walls of the cigarettes; two lateral walls on opposite sides of the front wall and contacting the cylindrical lateral walls of the cigarettes; and a bottom wall contacting the tips of the cigarettes .
  • Patent Application O2011110272A1 describes a packing method for producing a sealed inner package containing a group of cigarettes. As a whole, the packing method described is substantially conventional, by causing the group of cigarettes to intercept a flat sheet of packing material, so that the sheet of packing material folds into a ⁇ ' about the group of cigarettes.
  • Patent Application O2011110272A1 proposes a further packing method for producing a sealed inner package containing a group of cigarettes.
  • This further method is based on the so-called ⁇ flow-pack' method, in which a tubular wrapping is formed about a succession of groups of cigarettes by continuously and longitudinally heat- sealing a web of packing material folded into a tube; and the tubular wrapping is heat-sealed and cut transversely, upstream and downstream from each group of cigarettes, into individual sealed inner packages:
  • each group of cigarettes may possibly fall out of shape, i.e. the cigarettes in the group may shift out of position, thus resulting in the formation of an irregularly shaped sealed inner package which is inevitably rejected.
  • a package of tobacco articles comprising a sealed inner package, as claimed in the accompanying Claims.
  • Figure 1 shows a front view in perspective of a packet of cigarettes, in accordance with the present invention, in a closed configuration
  • Figure 2 shows a front view in perspective of the Figure 1 packet of cigarettes in an open configuration

  • Number 1 in Figures 1, 2 and 3 indicates as a whole a rigid packet of cigarettes.
  • Packet 1 of cigarettes comprises a cup- shaped outer container 2, which is made of cardboard, has a hinged lid, and houses a sealed inner package 3 (Figure 2) .
  • Sealed inner package 3 encloses a parallelepiped- shaped group 4 of cigarettes ( Figure 5) and, at the top and front, has a central cigarette extraction opening 5 extending over part of a front wall and part of a top wall of sealed inner package 3.
  • the cigarettes in group 4 are cylindrical with a longitudinal axis.
  • Sealed inner package 3 comprises a reclosable (i.e. ⁇ pen-close' ) sealing flap (i.e.
  • sealing panel 6 designed to seal extraction opening 5 and coated on the underside with non-dry, re- stick glue (i.e. non-dry glue allowing the sealing flap to be detached and re-attached repeatedly) . That is, sealing flap 6 normally adheres to sealed inner package 3 to seal extraction opening 5, and can be detached temporarily from sealed inner package 3 to free, and so withdraw a cigarette through, extraction opening 5.
  • sealing flap 6 is applied externally to the packing material of sealed inner package 3.
  • sealing flap 6 is either formed in two- layer packing material of sealed inner package 3, or is in the form of a frame applied to the inside of the packing material of sealed inner package 3.
  • sealing flap 6 has a grip tab 7 with no re- stick adhesive and located close to, normally beneath, extraction opening 5.
  • sealed inner package 3 comprises a U-shaped stiffener (i.e. tray) 8 made of cardboard (identical to that of outer container 2) and which is inserted inside sealed inner package 3, contacting group 4 of cigarettes .
  • Stiffener 8 comprises a front wall 9 positioned contacting the cylindrical lateral walls of the cigarettes in group 4; two lateral walls 10 on opposite sides of front wall 9 and positioned contacting the cylindrical lateral walls of the cigarettes in group 4; and a bottom wall 11 positioned contacting the tips of the cigarettes in group 4.
  • Front wall 9 preferably has a top recess 12 located at cigarette extraction opening 5, so that front wall 9 does not overlap cigarette extraction opening 5.
  • Each lateral wall 10 comprises a lateral tab 13, which is folded 90° with respect to lateral wall 10 onto bottom wall 11.
  • Bottom wall 11 comprises a bottom tab 14, which is folded 180° with respect to and onto bottom wall 11; and bottom tab 14 comprises an appendix 15, which is folded 90° with respect to bottom tab 14 onto front wall 9.
  • Stiffener 8 has no glue, and comprises a jointing system to hold bottom wall 11 and lateral walls 10 in position.
  • the jointing system comprises a U-shaped through slit 16 formed through front wall 9, along the fold line between front wall 9 and bottom wall 11; and a U-shaped projection 17 formed on bottom tab 14, along the fold line between bottom tab 14 and appendix 15.
  • Projection 17 on bottom tab 14 is inserted through slit 16 in front wall 9 (by elastically deforming projection 17) to form a joint, between projection 17 and through slit 16, which holds bottom wall 11 and lateral walls 10 in position, by requiring significant deformation for its release.
  • Through slit 16 is formed by making a U- shaped cut through front wall 9, along the fold line between front wall 9 and bottom wall 11.
  • projection 17 is formed by making a U-shaped cut through appendix 15, along the fold line between appendix 15 and bottom tab 14.
  • stiffener 8 serves to reinforce and maintain the shape of sealed inner package 3 , to prevent sealed inner package 3 from collapsing, when some of the cigarettes are removed, and so complicating withdrawal of the remaining cigarettes and, in particular, opening and closing of sealing flap 6.
  • stiffener 8 serves to hold the cigarettes in group 4 together in the right position.
  • Figure 9 shows a blank 18, which is folded to form the stiffener 8 in Figures 6, 7 and 8.
  • Figure 8 clearly shows the cuts defining through slit 16 and projection 17.
  • Figure 10 shows a variation of the Figure 9 blank 18.
  • The. Figure 10 blank 18 differs from the Figure 9 blank 18 by comprising a ⁇ logo' , which is visible in positive form at top recess 12 (i.e. at the part of stiffener 8 visible through extraction opening 5 of sealed inner package 3) , and in negative form at bottom tab 14 and appendix 15 (in this way, the Figure 10 blank 18 can be formed from a continuous web of cardboard with no waste) .

  • stiffener 8 chooses which of the above embodiments of stiffener 8 to employ depends on the relationship between the thickness of group 4 of cigarettes (and therefore the size of bottom wall 11 of stiffener 8) and the size of recess 12 (which, to avoid waste, also affects the shape and size of bottom tab 14 and appendix 15).
  • Number 26 in Figure 32 indicates as a whole a packing machine for producing packet 1 of cigarettes in Figures 1, 2 and 3.
  • Packing machine 26 comprises a packing section 27 for producing sealed inner packages 3; and . a follow-up packing section 28 for producing outer containers 2 by folding rigid blanks 29 about the sealed inner packages 3 from packing section 27.

  • Slide surface 47 has a through opening, through which a stiffener 8 is raised by elevator 47a.
  • elevator 47a is moved into the bottom position to pick up a stiffener 8, and is then raised to feed stiffener 8 into coupling station 43, where stiffener 8 intercepts and couples with a corresponding group 4 of cigarettes (i.e.
  • group 4 of cigarettes impacts bottom wall 11 of stiffener 8, thus drawing stiffener 8 along with it) .
  • the end of slide surface 47 around the through opening is designed to finish folding bottom tab 14 and appendix 15 as stiffener 8 is pushed up by elevator 47a.
  • packing unit 32 comprises a packing conveyor 48, which feeds each group 4 of cigarettes (fitted with respective stiffener 8) along a straight packing path P.
  • a fixed folding device 49 (shown schematically in Figure 35) winds strip 33 of packing material longitudinally, i.e. parallel to packing path P, about packing path P to bring the two opposite edges of strip 33 of packing material into contact and so form a tubular wrapping enclosing groups 4 of tobacco articles (fitted with respective stiffeners 8) .
  • Packing unit 32 also comprises a heat-sealing device 50 (shown schematically in Figures 35 and 40) located downstream from folding device 49, and which heat-seals the two opposite overlapping edges of strip 33 of packing material longitudinally, i.e.
  • Packing unit 32 also comprises a heat-sealing device 51 (shown schematically in Figures 35 and 40) located downstream from heat-sealing device 50, and which heat- seals and cuts the tubular wrapping transversely, i.e. perpendicularly to packing path P, upstream and downstream from each group 4 of cigarettes (fitted with respective stiffener 8) , to complete sealed inner packages 3.

  • packing conveyor 48 feeds each group 4 of cigarettes (fitted with respective stiffener 8) transversely along packing path P, i.e. with the longitudinal axes of the cigarettes perpendicular to packing path P and to the longitudinal heat-seal, and parallel to the transverse heat-seals. Feeding groups 4 of cigarettes along the packing path in this way is extremely important, by enabling the formation of sealed inner packages 3 with the transverse heat- seals along the lateral walls, and with no heat- seals at all on the bottom wall and, more importantly, on the top wall in which extraction opening 5 is formed.
  • strip 33 of packing material is already complete with extraction openings 5 covered with open- close sealing flaps 6, which are formed and applied respectively at work stations (not shown) upstream from packing unit 32.
  • extraction openings 5 covered with open-close sealing flaps 6 are located on the opposite side of the tubular wrapping to the longitudinal heat- seal, and are centred between the two transverse heat-seals.
  • extraction openings 5 covered with open-close sealing flaps 6 may be located on the same side as the longitudinal heat-seal and, as opposed to being centred, may be more or less asymmetrical in shape and/or position.
  • packing conveyor 48 comprises a static (i.e. stationary) slide surface 52, along which each group 4 of cigarettes slides, and about which strip 33 of packing material is wound; and a push device 53 located over groups 4 of cigarettes, and which pushes each group 4 of cigarettes along packing path P.
  • Push device 53 comprises a conveyor belt 54, which is located over each group 4 of cigarettes, extends parallel to packing path P, presses each group 4 of cigarettes against slide surface 52, and comprises paddles 55, which project from conveyor belt 54 and are positioned upstream and downstream from, to define a seat for, each group 4 of cigarettes.
  • packing unit 32 comprises a feed conveyor 56, which receives groups 4 of cigarettes from coupling conveyor 42 at input station 44, and feeds groups 4 of cigarettes onto slide surface 52.
  • Feed conveyor 56 comprises two parallel, side by side conveyor belts 57 located beneath groups 4 of cigarettes, and on which groups 4 of cigarettes rest.
  • Each conveyor belt 57 comprises paddles 58, which project from conveyor belt 57 and are positioned upstream and downstream from, to define a seat for, each group 4 of cigarettes.
  • packing unit 32 comprises two conveyor belts 59 positioned facing each other on opposite sides of packing path P, directly upstream from heat-sealing device 50.
  • the two conveyor belts 59 press on opposite sides of the tubular wrapping to compress the two opposite longitudinal, edges of the tubular wrapping transversely (i.e. the two conveyor belts 59 press on the longitudinally oriented bottom wall and top wall of each sealed inner package 3 in the making) .
  • longitudinally heat-sealing by means of heat-sealing device 50 the two opposite overlapping edges of strip 33 of packing material to stabilize the tubular wrapping produces a longitudinal fin 60, which initially projects perpendicularly from the tubular wrapping.
  • heat-sealing device 50 forming the longitudinal heat-seal is connected to a folding device, which folds the longitudinal fin 60 ninety degrees and presses it onto the tubular wrapping.
  • each transverse heat- seal (by heat- sealing device 51) on the tubular wrapping produces a transverse fin 61, which initially projects perpendicularly from (i.e. from a lateral wall of) the . corresponding sealed inner package 3.
  • a folding device downstream from heat-sealing device 51 folds each transverse fin 61 ninety degrees and presses it onto the corresponding sealed inner package 3 (i.e. onto a lateral ., wall of the corresponding sealed package 3).
  • Each transverse fin 61 is preferably fixed (heat-sealed or glued) to the corresponding sealed inner package 3 (i.e. to a lateral wall of the corresponding sealed package 3) so that it remains permanently contacting sealed inner package 3.
  • each transverse fin 61 must be fixed to remain permanently contacting the corresponding sealed inner package 3
  • the transverse heat-seals provide for holding the longitudinal fin 60 permanently contacting the corresponding sealed inner package 3.
  • Figures 4b and 4c show a sealed inner package 3 prior to folding (fixing) the two transverse fins 61, and Figure 4a a sealed inner package 3 after the two transverse fins 61 are folded (fixed) .
  • each group 4 of cigarettes is formed on forming conveyor 35 independently and separately from the corresponding stiffener 8; each stiffener 8 is folded on folding conveyor 39 independently and separately from formation of the corresponding group 4 of cigarettes; and each pre-formed group 4 of cigarettes is coupled on coupling conveyor 42 with the corresponding pre- folded stiffener 8.
  • forming conveyor 35 for forming groups 4 of cigarettes extends parallel to and alongside folding conveyor 38 for folding stiffeners 8; whereas coupling conveyor 42, on -which each pre-formed group 4 of cigarettes is coupled with the corresponding pre-folded stiffener 8, is perpendicular to forming conveyor 35 and folding conveyor 38.
  • each stiffener 8 is fed into a forming pocket 36 on forming conveyor 35, upstream from hopper 34; and each group 4 of cigarettes is transferred from hopper 34 into forming pocket 36 (containing stiffener 8) and directly into stiffener 8.
  • folding conveyor 39 for folding stiffeners 8 is located upstream from forming conveyor 35 to feed stiffeners 8, already folded, to the start of forming conveyor 35.
  • Figures 41-43 show a simplified stiffener 8 with only front wall 9 and lateral walls 10 (i.e. with no bottom wall 11). Though, clearly, stiffener 8 in the Figure 41-43 embodiment may also be as described with reference to Figures 6-31.
  • packing unit 32 comprises a processing device for extracting air (by suction) from the tubular wrapping to form vacuum-sealed inner packages 3.
  • the processing device also injects inert gas to form controlled- atmosphere sealed inner packages 3.
  • packing machine 26 only comprises packing section 27 for producing sealed inner packages 3, which are marketed as they are, without outer containers 2 (i.e. each packet 1 of cigarettes only comprises a sealed package 3 , and has no outer container 2) ; or else a further packing machine (separate from and fully independent of packing machine 26) receives sealed inner packages 3 from packing machine 26, and forms outer containers 2 about sealed inner packages 3.
  • stiffener 8 comprises a system for connecting bottom wall 11 to lateral walls 10, and for preventing bottom wall 11 from moving with respect to lateral walls 10 (or, conversely, preventing lateral walls 10 from moving with respect to bottom wall 11) .
  • This connecting system in fact, increases the rigidity of stiffener 8 and so further prevents unwanted movements of the cigarettes in group 4, particularly when forming the tubular wrapping.
  • the system connecting bottom wall 11 and lateral walls 10 has no glue, thus eliminating any glue inside sealed inner package 3, and the possibility of the substances in the glue somehow altering the taste and/or aroma of the tobacco in the cigarettes.
  • packet 1 of cigarettes described may also be used for producing a carton of cigarettes, which is substantially the same as packet 1 described, except that it contains a group of packets of cigarettes as opposed to a group of cigarettes, or for producing a packet of cigars or similar, which is substantially the same as packet 1 described, except that it contains a group of cigars or similar, as opposed to a group of cigarettes.
