Definitions

  • the present invention relates to a sealed package internally provided with a rigid stiffener and corresponding packing method and packing machine.
  • the present invention finds advantageous application to a sealed package of cigarettes and provided with a reclosable extraction opening, to which the following description will make explicit reference without loss of generality.
  • a rigid package of cigarettes with a hinged lid comprises an inner package which encloses a group of cigarettes and a rigid outer casing which houses the inner package in the inside thereof.
  • the inner package which is formed by folding and heat-sealing a sheet of waterproof packing material.
  • the inner package is provided with a sealed extraction opening which is normally covered by an adhesive panel of the type "open and close”; in particular, the adhesive panel is provided with non-dry, re-stick adhesive which allows to fix several times the adhesive panel in a closing position of the cigarette extraction opening.
  • the sealed inner package is internally provided with a rigid stiffener which has essentially the function of giving greater stiffness and greater shape stability to the sealed inner package so as to prevent the sealed inner package from collapsing on itself after removing a part of the cigarettes enclosed in the inside thereof complicating the extraction of the remaining cigarettes and, in particular, making extremely complicated the opening and the subsequent closing of the adhesive panel.
  • a further function of the stiffener is to maintain the group of cigarettes in the correct conformation, as well as provide adequate mechanical protection to the group of cigarettes, during the formation of the sealed inner package (i.e. during the folding/heat sealing of the sheet of packing material).
  • the stiffener has a "U" shape and comprises a front wall having a top window to leave exposed a top area of the group of cigarettes at the extraction opening, and two lateral walls arranged on opposite sides of the front wall.
  • the patent application WO2013053408A1 describes a sealed inner package wherein the stiffener is provided with a bottom wall, two lateral stabilizing tabs which are connected to the lateral walls and are folded 90° onto an inner surface of the bottom wall, and with a central stabilizing tab which is connected to the bottom wall and is folded 180° onto the inner surface of the bottom wall and over the two previously folded lateral stabilizing tabs.
  • the central stabilizing tab has a tip that is inserted within a slot formed through the front wall to obtain a mechanical interlocking which stabilizes the folded configuration of the support element.
  • the folded configuration of the support element is extremely stable; however, obtaining said mechanical interlocking in a packing machine is extremely complex and relatively unreliable (in other words, relatively often the mechanical interlocking is not correctly implemented, and then the support element does not have a stable folded configuration).
  • the patent application WO2013053408A1 describes a sealed inner package wherein the stiffener is provided with a bottom wall, two lateral stabilizing tabs which are connected to the lateral walls and are folded 90° onto an inner surface of the bottom wall, and a central stabilizing tab which is connected to the bottom wall and is folded 90° onto a side wall of the group of cigarettes (therefore away from the two lateral stabilizing tabs previously folded).
  • the stiffener described in patent application WO2013053408A1 has a modest mechanical stability (in the absence of glue) and therefore requires a relatively complex manipulation of the group of cigarettes during the formation of the sealed inner package (i.e. during the folding/heat sealing of the sheet of packing material).
  • Purpose of the present invention is to provide a sealed package internally provided with a rigid stiffener and corresponding packing method and packing machine, which package, packing method and packing machine are devoid of the drawbacks described above and are, at the same time, easy and economical to produce.
  • FIGs 1, 2 and 3 number 1 indicates as a whole a rigid package of cigarettes.
  • the package 1 of cigarettes comprises an outer container 2 made of cardboard or rigid paperboard and cup-shaped and a sealed package 3 (better illustrated in Figures 4 and 5 ) housed inside the container 2.
  • the outer container 2 has an open top end and is provided with a lid, which is cup-shaped and is hinged to the outer container 2 along a hinge (shown in Figure 3 ) to rotate, with respect to the outer container 2, itself, between an opening position (illustrated in Figure 2 ) and a closing position (shown in Figures 1 and 3 ) of the open top end.
  • the lid when in its closing position, gives the outer container 2 a rectangular parallelepiped shape having a top wall and a bottom wall opposite and parallel one with respect to the other, a front wall and a rear wall (wherein the hinge is formed) opposite and parallel one with respect to the other, and two lateral walls opposite and parallel one with respect to the other. Between the lateral walls and the front and rear walls four longitudinal edges are defined, while between the top and bottom walls and the front, rear and lateral walls eight transverse edges are defined.
  • the sealed package 3 encloses a group 4 of cigarettes (shown in Figure 6 ) of parallelepiped shape and has a top and a front cigarettes extraction opening 5 (shown in dashed lines in Figure 4 ); the cigarette extraction opening 5 is arranged centrally, is closed by an adhesive panel 6 of the type "open & close” and affects a portion of a front wall of the sealed package 3 and a portion of a top wall of the sealed package 3.
  • the adhesive panel 6 normally adheres to the part of the sealed package 3 arranged about the extraction opening 5 to close (seal) the extraction opening 5 itself and may be temporarily lifted to free the extraction opening 5, and then allows the extraction of a cigarette through the extraction opening 5 itself.
  • the sealed package 3 is obtained by wrapping a sheet 7 of waterproof and heat-sealable packing material (shown in Figure 8 ), which has a rectangular shape and has an incision which is "U" shaped and defines the extraction opening 5.
  • a sheet 7 of packing material shown in Figure 8
  • an adhesive panel 6 is glued, which has a rectangular shape and completely covers the incision (i.e. the extraction opening 5); between the adhesive panel 6 and the sheet 7 of packing material a non-dry, re-stick adhesive is interposed (i.e. which always remains sticky), i.e. an adhesive which allows even after a long time to separate the adhesive panel 6 from the sheet 7 of packing material and then to assemble again the adhesive panel 6 to the sheet 7 of packing material for a greater number of times.
  • the non-dry, re-stick adhesive is previously applied to an inner face of the adhesive panel 6 before fitting the adhesive panel 6 to the sheet 7 of packing material.
  • the presence of the re-stick adhesive between the panel 6 and the sheet 7 of packing material determines the permanent gluing (i.e. that also in use is never separated) of the portion of the sheet 7 of packing material enclosed within the incision (i.e. in correspondence with the extraction opening 5) to the adhesive panel 6; therefore, when the adhesive panel 6 is lifted from the sheet 7 of packing material the portion of the adhesive panel 6 enclosed within the incision (i.e. in correspondence of the extraction opening 5) is lifted together with the adhesive panel 6 freeing the extraction opening 5.
  • the presence of the re-stick adhesive between the adhesive panel 6 and the sheet 7 of packing material determines a temporary gluing (i.e. that in use is separated) between the portion of the sheet 7 of packing material surrounding the incision (i.e. that surrounds the extraction opening 5) and the adhesive panel 6 so as to normally maintain the adhesive panel 6 into contact with the sheet 7 of packing material to close (seal) the extraction opening 5.
  • the adhesive panel 6 is provided with a graspable tab 8, which is free of re-stick adhesive on the side facing the sheet 7 of packing material (i.e., the surface facing the sheet 7 of packing material) and is arranged in the vicinity of the extraction opening 5 and below the extraction opening 5 itself.
  • the graspable tab 8 is likely to facilitate the gripping of the adhesive panel 6 at the time of lifting the adhesive panel 6 itself; in other words, to lift the adhesive panel 6, a user can easily grab a graspable tab 8, which is in no way fixed to the sheet 7 of packing material in contrast to the rest of the adhesive panel 6.
  • the sealed package 3 is stabilized, or is maintained in the folded configuration, by a fin shaped central heat seal 9 (or longitudinal heat seal 9) arranged at a front wall and lateral walls of the sealed package 3 and by means of two fin shaped lateral welds 10 (or transverse welds 10) that are arranged at the lateral walls of the sealed package 3.
  • the fin shaped central heat seal 9 determines the formation of a tubular package having two open ends at the lateral walls of the sealed package 3 and is initially perpendicular to the front wall of the sealed package 3; subsequent to its formation, the fin shaped central heat seal 9 is folded 90° onto the front wall of the sealed package 3 (as illustrated in Figures 4 and 7 ).
  • the two fin shaped lateral welds 10 determine the lateral closure of the tubular package and are initially perpendicular to the corresponding lateral walls of the sealed package 3 (as shown in Figure 7 ); subsequently to the formation thereof, the two fin shaped lateral welds 10 are folded 90° onto the corresponding lateral walls of the sealed package 3 (as illustrated in Figures 4 and 5 ).
  • each fin shaped lateral heat seal 10 is obtained by determining the formation of two triangular end tabs 11 which protrude from opposite sides from the corresponding lateral wall of the sealed package 3; after folding each fin shaped lateral heat seal 10 by 90° onto the corresponding side wall of the sealed package 3, the two triangular end tabs 11 are folded 180° onto the corresponding side wall of the sealed package 3 and over the previously folded fin shaped lateral heat seal 10.
  • each triangular end tabs 11 is heat-sealed to the corresponding side wall of the sealed package 3 to remain in the desired position illustrated in Figures 4 and 5 ; alternatively, each triangular end tabs 11 may be maintained in the desired position illustrated in Figures 4 and 5 only by the presence of the outer container 2 which surrounds the sealed package 3.
  • the sealed package 3 comprises a stiffener 12, which is made of cardboard or rigid paperboard (entirely similar to the cardboard or rigid paperboard forming the outer container 2), is "U" shaped and is arranged within the sealed package 3 contacting the group 4 of cigarettes.
  • the stiffener 12 comprises a front wall 13 of rectangular shape arranged into contact with a front wall of the group 4 of cigarettes, two lateral walls 14, which are connected to opposite sides of the front wall 13 and are arranged into contact with the lateral walls of the group 4 of cigarettes, and a bottom wall 15 arranged into contact with the bottom wall of the group 4 of cigarettes.
  • the front wall 13 which has a top, U-shaped window, and facilitates the extraction of the cigarettes from the group 4 of cigarettes as it leaves exposed a top area of the front wall of the group 4 of cigarettes at the extraction opening 5.
  • the stiffener 12 comprises two lateral stabilizing tabs 16 which are connected to the lateral walls 14 and are folded 90° onto an outer surface of the bottom wall 15 (or from the opposite side with respect to the group 4 of cigarettes), and a central stabilizing tab 17 which is connected to the bottom wall 15 and is folded 180° onto the outer surface of the bottom wall 15 (or from the opposite side with respect to the group 4 of cigarettes) and over the two lateral stabilizing tabs 16 previously folded.
  • the two lateral stabilizing tabs 16 are connected to the corresponding lateral walls 14 of the stiffener 12 along two transverse fold lines and the central stabilizing tab 17 is connected to the bottom wall 15 of the stiffener 12 along a further transverse fold line which is initially parallel to the other two transverse fold lines.
  • the function of the stiffener 12 is to give greater stiffness and greater shape stability to the sealed package 3 so as to prevent the sealed package 3 from collapsing on itself after removing a part of the cigarettes enclosed in the sealed package 3 itself making the extraction of the remaining cigarettes complicated and, in particular, making the opening and the subsequent closing of the adhesive panel 6 extremely complicated.
  • the functions of the stiffener 12 are to provide adequate mechanical protection to cigarettes and to simplify/improve the handling of the group 4 of cigarettes (i.e. to prevent the group 4 of cigarettes from coming apart).
  • the packing machine 18 comprises a packing unit 19 which provides the initial sealed package 3 by forming the group 4 of cigarettes and wrapping and heat sealing the sheet 7 of packing material about the group 4 of cigarettes and an end packing unit 20 (known and illustrated in a very schematic way) which forms the outer container 2 by wrapping one after the other a collar and a blank about the sealed package 3.
  • the initial packing unit 19 comprises a group-forming station 21 wherein the group 4 of cigarettes is formed, an application station 22 wherein the group 4 of cigarettes is fitted with a stiffener 12, and a packing station 23 wherein the sheet 7 of packing material is wrapped about the group 4 of cigarettes to form the sealed package 3.
  • the group-forming station 21 comprises a vertical hopper 24 provided with a plurality of lower outlet mouths, and a group-forming conveyor belt 25 which supports a plurality of group-forming pockets 26 and travels with continuous motion for moving the group-forming pockets 26 themselves along a group-forming path P1 (shown in figure 16 ) which extends in front of the outlet mouths of the hopper 24.
  • the group-forming conveyor 25 comprises a belt which is closed as a ring and wraps about two motorized end pulleys; accordingly, the group-forming path P1 is "U" shaped and has a lower rectilinear branch which extends horizontally and is arranged in front of the outlet mouths of the hopper 24, and a top rectilinear branch which passes through the application station 22 and ends at a transferring device 36 which transfers each group 4 of cigarettes enclosed in a group-forming pocket 26 in a wrapping seat 27 of a packing conveyor 28 which travels with continuous motion in parallel and in synchronism with the group-forming conveyor 25 for moving the seats 27 of packing material along a rectilinear and horizontal packing path P2.
  • the two motorized end pulleys are movable with a reciprocating linear motion parallel to the rectilinear sections of the group-forming path P1; at the same time, the rotation speed of the two motorized end pulleys is variable in time, in synchronism with their reciprocating linear motion.
  • the combination of the pulleys reciprocating linear motion with the variation of the rotation speed of the pulleys themselves allows to temporarily stop the group-forming pockets 26 that are arranged in front of the outlet mouths of the hopper 24 (i.e.
  • the group-forming pockets 26 that are arranged in the lower rectilinear branch of the group-forming path P1) to allow transferring the groups 4 of cigarettes from the outlets mouths of the hopper 24 to the group-forming pockets 26; at the same time, the combination of the reciprocating linear motion of the pulleys with the variation of the rotation speed of the pulleys themselves allows to keep constant the feeding speed of the group-forming pockets 26 in the top branch of the rectilinear group-forming path P1, so that the group-forming pockets 26 which are arranged in the top rectilinear branch of the group-forming path P1 are always in phase and synchronized with the packing seats 27 of the packing conveyor 28 (fed with continuous motion along the packing path P2).
  • the application station 22 comprises an application belt conveyor 29 that is arranged next to the group-forming conveyor 25 so as to feed the stiffener 12 in parallel to the top rectilinear branch of the group-forming path P1.
  • the application conveyor 29 is provided with suction and holds the stiffener 12 by suction into contact with a lower surface of the conveyor belt; in other words, and as clearly shown in figure 18 and 19 , the application conveyor 29 is arranged over the group-forming conveyor 25 and the stiffener 12 is hung by suction below the application conveyor 29.
  • a feeding device 30 which unwinds from a reel 31, a continuous strip of packing material that is fed along a rectilinear and horizontal feeding path P3 which extends perpendicularly to the application conveyor 29.
  • the continuous strip of packing material is passed through an embossing and cutting device 32 to form the pre-weakened fold lines in each stiffener 12, and then to separate from the continuous belt itself individual stiffeners 12.
  • a lifter 33 is arranged which is movable vertically (i.e. perpendicular to the feeding path P3 and to the application conveyor 29) with reciprocating motion; the lifter 33 pushes the stiffener 12 of the final portion of feeding path P3 to the application conveyor 29 to which the stiffener 12 adheres by suction.
  • the application conveyor 29 of the application station 22 cooperates with the group-forming conveyor 25 for resting the stiffener 12 on the group-forming pocket 26 along the top rectilinear branch of the group-forming path P1. While the stiffener 12 rests on the group-forming pocket 26 (i.e. along the top rectilinear branch of the group-forming path P1) a pair of folding devices 34 and 35 (illustrated schematically in Figure 16 ) arranged in succession fold (as described previously and as illustrated in Figures 9 and 10 ) the stiffener 12 partially about the group-forming pocket 26, and then partially about the group 4 of cigarettes enclosed in the group-forming pocket 26.
  • a transferring device 36 extracts together and simultaneously the stiffener 12 and the group 4 of cigarettes from the group-forming pocket 26 to insert the stiffener 12 and the group 4 of cigarettes in the corresponding packing pocket 27 of the packing conveyor 28.
  • the group-forming pocket 26 comprises an initial part 37 arranged at an inlet opening of the group 4 of cigarettes (i.e. in correspondence of the opening through which the group 4 of cigarettes enters the group-forming pocket 26), and an end part 38 arranged at an outlet opening of the group 4 of cigarettes (i.e. in correspondence of the opening through which the group 4 of cigarettes exits the group-forming pocket 26).
  • the stiffener 12 is supported only on the end part 38 of the group-forming pocket 26 so that initially the stiffener 12 is longitudinally misaligned with respect to the group 4 of cigarettes and is longitudinally aligned with the group 4 of cigarettes only when extracted from the group-forming pocket 26 along with the group 4 of cigarettes.
  • the group-forming pocket 26 is tubular shaped with a rectangular section and comprises a bottom wall and a top wall opposite and parallel one with respect to the other (visible in Figures 18 and 19 ) and two lateral walls opposite and parallel one with respect to the other (not visible in Figures 18 and 19 ); the top and lateral wall thickness of the end part 38 is less than the thickness of the top and lateral walls of the initial portion 37 so that the stiffener 12 resting on the final part 38 of the group-forming pocket 26 is arranged in close proximity to the group 4 of cigarettes.
  • a first end of the front wall 13 of the stiffener 12 is placed on the group-forming pocket 26 and a second end of the front wall 13 of the stiffener 12 opposite to the first end is retained by suction by the application conveyor 29 which travels parallel to the group-forming conveyor 25.
  • a lower surface of the front wall 13 of the stiffener 12 rests on the group-forming pocket 26 (in particular on the top wall of the group-forming pocket 26), while a top surface opposite the lower surface of the front wall 13 of the stiffener 12 is in contact with the application conveyor 29 that holds the latter by suction.
  • the folding device 34 folds the stiffener 12 about the group-forming pocket 26 while the front wall 13 of the stiffener 12 is retained by the application conveyor 29.
  • the folding device 34 comprises a folding device 39 that travels vertically (i.e. transversely to the group-forming path P1) between a resting position (shown in Figures 18 and 20 ) wherein the folding device 39 is away from the stiffener 12 and a working position (shown in Figures 19 and 21 ) wherein the folding device 39 spans over the stiffener 12 itself.
  • the folding device 39 is also movable parallel to group-forming path P1 to follow the group-forming pocket 26 along a portion of group-forming path P1 itself.
  • the folding device 39 comprises four "legs" 40 (i.e., four folding elements 40) oriented vertically spanning over the front and the rear of the application conveyor 29 and embracing laterally the stiffener 12; when the folding device 39 moves from the resting position (shown in Figures 18 and 20 ) to the working position (shown in Figures 19 and 21 ), the four folding elements 40 fold 90° the lateral walls 14 of the stiffener 12 with respect to the front wall 12 of the stiffener 12.
  • the folding device 39 comprises a further folding element 41 (shown in Figures 20 and 21 ) which is arranged transversely to two rear folding elements 40; when the folding device 39 moves from the resting position (shown in Figures 18 and 20 ) to the working position (shown in Figures 19 and 21 ), the further folding element 41 folds 90° the rear wall 15 of the stiffener 12 with respect to the front wall of the stiffener 12.
  • the folding device 39 cooperates with a counter-folding device 42 that is "U" shaped and, when the folding device 39 moves towards the working position (shown in Figures 19 and 21 ), it rests against an inner surface of the front wall 13 of the stiffener 12 from the opposite side with respect to the same folding device 39.

  • the transverse heat seal device 49 comprises two heat seal drums 58 that are rotatably mounted about respective central rotation axes 59 parallel one with respect to the other, are arranged on opposite sides of the packing path P2 along which the tubular package is fed, and bring respective heat seal heads 60 cooperating one with the other to clamp between them the tubular package during the performing of the transverse heat seal 10.
  • the heat seal heads 60 are internally provided with cutting members 61 to obtain, during the performing of the transverse welds 10, a transverse cut of the tubular package so as to separate a sealed package 3 from the tubular package itself.
  • each heat seal drum 58 is covered by a compression element 62 that is elastically deformed to impart a compression on the tubular package in order to stretch the tubular package, and then remove the air trapped inside the tubular package during the execution of the transverse welds 10; normally, the compression element 62 is formed by brushes.
  • Each heat seal head 60 of a heat seal drum 58 is coupled to a corresponding support element 63 that is carried by a corresponding heat seal drum 58, is arranged downstream of the corresponding heat seal head 60 with respect to the feeding direction of the tubular package along the packing path P2, and comes in contact with a bottom or top wall of the tubular package itself.

  • each support element 63 Upon execution of the transverse heat seal 10, each support element 63 advances for a certain distance with a linear movement parallel to the packing path P2 to accompany the sealed package 3 which has just been separated from the continuous tubular package.
  • each support element 63 is mounted movable with respect to the corresponding heat seal drum 58 to perform a relative movement with respect to the heat seal drum 58 itself; in particular, each support element 63 is rotatably mounted with respect to the corresponding heat seal drum 58 to rotate about a peripheral rotation axis 64 parallel to the central rotation axis 59.
  • each heat seal drum 58 comprises a camshaft implementing system 65 for controlling the relative movement (i.e. the relative rotation) between each support element 63 and the heat seal drum 58 itself.

  • the conveyor belt 55 starts, towards which the sealed packages 3 are pushed coming from the same transverse heat seal device 49; the support elements 63 guide each sealed package 3 towards the conveyor belt 55 to ensure a correct introduction of the sealed package 3 in the conveyor belt 55 itself, or to prevent the sealed package 3 from jamming against the conveyor belt 55 itself due to unwanted movements that can take place after the execution of the transverse heat seal 10.
  • a pressure drum is arranged that is covered by an element that is elastically deformed (typically brushes) and that pushes the sealed package 3 against the conveyor belt 55.
  • each transverse heat seal 10 is interrupted in a limited portion of the tubular package so as to leave, astride of the transverse heat seal 10, at least one vent channel 67 that connects the inside of the sealed package 3 with the outside environment.
  • the vent channel 67 is closed after the execution of the transverse welds 10 to make the sealed package 3 airproof.
  • the vent channel 67 is closed by a sealing that is performed after performing the transverse welds 10 and which coincides with the heat seal performed by the heat seal device 54 for heat sealing the fin shaped transverse welds 10 and/or the triangular end flaps to the underlying part of the sheet 7 of packing material.
  • the same heat sealing performed by the heat seal device 54 has both the function to close the vent channel 67 and the function of fixing the fin shaped transverse welds 10 and/or the triangular end flaps to the underlying part of the sheet 7 of packing material.
  • each heat seal head 60 has a heated surface 68, which is centrally interrupted by the presence of cutting member 61 and is pressed against the overlapping portions of the sheet 7 of packing material in order to achieve a corresponding transverse heat seal 10.
  • the heated surface 68 has at least one recess 69 in correspondence of which the transverse heat seal 10 is interrupted to leave the vent channel 67.
  • the vent channel 67 allows to evacuate (fully or partially) the air inside the sealed package 3 before airproof closing the sealed package 3 itself.
  • the sealed package 3 remains open towards the outer environment for the presence of the vent channel 67 (or of the vent channels, as there could be even more vent channels); in this way, the air inside the sealed package 3 can be evacuated (fully or partially) after performing the transverse welds 10.
  • the vent channel 67 itself is closed to make the sealed package 3 airproof by using the same heat sealing with which the fin shaped transverse welds 10 and/or the triangular end flaps are fixed to the underlying part of the sheet 7 of packing material.
  • the vent channel 67 itself is closed to make the sealed package 3 airproof by a further heat sealing that is different (i.e. performed at different times and by different members) from the heat seal performed by the heat seal device 54.
  • the initial packing unit 19 of the packing machine 18 is "L" shaped and has a front side (shown in Figure 15 ) wherein the members that perform the various packing operations are arranged and a lateral side (shown in Figure 14 ) wherein all the feeding of the packing materials are arranged (i.e. of the sheets 7 of packing material and of the stiffeners 12).
  • Figure 14 can be recognized the two coils 31 (one as a reserve to the other) from which the continuous strip of packing material is unwrapped for the formation of the stiffeners 12 and the two coils 70 (one as a reserve to the other) from which the continuous strip of packing material for the formation of the sheets 7 of packing material is unwrapped.
  • the stiffener 12 of the sealed package 3 above described has numerous advantages.
  • the stiffener 12 described above may be mechanically stabilized in the desired folded configuration simply by pushing from the outside (i.e. from the opposite side with respect to group 4 of cigarettes) with a pad on the bottom wall 15 (or better on the stabilizing tabs 16 and 17 that cover the outside of the bottom wall 15).
  • the mechanical stabilization of the stiffener 12 is obtained in a simple, safe and reliable way, and without any use of glue; the use of glue inside sealed package 3 is problematic, since the glue can release volatile substances that undesirably alter the cigarettes aroma.
  • stiffener 12 described above is simple and economical to produce, as a succession of stiffeners 12 can be sheared without wastage from a continuous strip of packing material; in this regard it is noted as the central stabilizing tab 17 exactly reproduces the shape of the top window of the front wall 13.
  • the sealed package 3 of the present invention contains a group 4 of cigarettes; thanks to the numerous advantages of the sealed package 3 of the present invention, said sealed package 3 can be also used to contain articles other than cigarettes, such as food (candies, chocolates or other sweets).
