Definitions

  • This invention relates to the packaging of smoking articles, typically cigarettes, in sealed blister-pack type packages, the invention is more particularly concerned with sealing an array of smoking articles within a single blister-pack compartment.
  • Blister tray type packaging is known for many articles, including medical products, foodstuff and the like.
  • Cigarettes are typically sold in packs of twenty or thirty cigarettes, typically within a crush-proof hinge-lid pack, or a crushable soft pack.
  • a light smoker or a smoker who is trying to give up smoking might not wish to purchase a full pack of cigarettes.
  • cigarettes are not typically sold in small numbers, other than in informal sale arrangements. Opening of packets and supplying cigarettes in small numbers is both unhygienic and can lead to the supply of inferior product. Also, traditional cigarette products tend to be expensive to manufacture.
  • a blister pack comprising a first blister tray formed with a plurality of trough formations in parallel, side-by-side relationship, each trough formation being shaped to accommodate an array of two to ten smoking articles, with adjacent trough formations being spaced apart from one another by planar lands to which a peelable or rupturable backing film is laminated so as to define a plurality of individually sealed compartments, with each array of smoking articles being individually accessible by rupturing or peeling away that portion of the backing film covering the array.
  • trough-receiving recesses are defined between adjacent trough formations, the trough-receiving recesses being sized to receive second trough formations of a second overlying blister tray in a snug complemental fit.
  • the second blister tray forms part of a second separate blister pack.
  • the first blister tray is hinged to the second blister tray.
  • Lines of weakness may extend through adjacent planar lands and/or the backing film for allowing the selective severing or opening of individual sealed compartments.
  • the backing film is provided with film access means.
  • the film access means may comprise a non-attached corner tag for allowing the film to be manually gripped prior to peeling.
  • the film access means may comprise a blister tray having a peeling recess spaced away from the planar level and defining an airgrap for allowing the film to be manually gripped prior to peeling.
  • the backing film may be laminated to the tray by means of a resealable adhesive adapted to allow access to be obtained to the smoking articles within the trough formation by peeling the backing film away from the tray, and resealing the backing film to the tray.
  • the backing film of each sealed compartment has identification indicia printed thereon relating to the contents of the compartment.
  • the indicia may be a bar code.
  • each of the elongate trough fonnations terminate in minor planar end walls which are spaced apart from one another by a distance corresponding to the lengths of the smoking articles, so that the inner surfaces of the end walls serve to retain tobacco particles within the smoking articles.
  • the invention extends to a blister pack comprising a first blister tray defining a first trough and a first trough-receiving recess adjacent the first frough, a second blister tray hinged to the first blister tray along a fold line and defining a second trough directly opposite the first recess and a second trough-receiving recess directly opposite the first trough.
  • the blister pack is foldable between an open position and a closed position in which the first trough locates complementally within the second recess and the second trough locates complementally within the first recess.
  • the first blister tray defines a row of first troughs alternating with a row of first recesses
  • the second blister tray defines a row of second troughs alternating with a rose of second recesses, the rows of first and second troughs being arranged to interdigitate with one another when folded together.
  • the troughs and recesses are substantially mirror images of each other such that when the first and second troughs are interdigitated with each other, a minimum of space exists between the first and second blister trays.
  • the first and second blister trays have planar substrates or lands and a peelable or rupturable backing film laminated to the planar substrates.
  • the troughs are preferably elongate troughs extending in a direction perpendicular to the fold line, the troughs being sized to accommodate an array of smoking articles.
  • a pair of parallel fold lines are provided, with the fold lines being spaced apart from one another by a distance corresponding to the depths of the compartments, such that the planar substrates are in opposed parallel relationship when the blister trays are folded together.
  • each of the trough formations are shaped so as to have a fluted configuration such that the inner surface of each trough defines a plurality of parallel elongate concave recesses adapted to receive and support said array of smoking articles in the trough formation in a closely stacked configuration.
  • the radius of curvature of each elongate concave recess is half the diameter of the smoking articles to be located in the trough formation.
  • Each trough formation may be of generally triangular, truncated triangular, trapezoidal or rectangular configuration so as to accommodate said array of smoking articles in a space efficient configuration.
  • a package comprising a tray formed with a plurality of sub-trays, each sub-tray having a trough formation shaped to accommodate at least one elongate rod-like article, with adjacent trough formations being surrounded and spaced apart from one another by planar lands to which a peelable or rupturable backing film is laminated so as to define a plurality of individually sealed compartments, with a fold line being defined in the land between each trough formation for allowing the sub-frays to be inwardly folded into a mutually nested position to define a cylindrical package, with the outer walls of the package being constituted by the backing film.
  • the package may be three-, four- or six-sided.
  • the package is four-sided so as to define a rectangular cylindrical package.
  • the outermost sub-trays are provided with a retaining arrangement for allowing them to be joined together, the retaining arrangement typically being in the form of an adhesive marginal flap.
  • the package may itself be at least partially wrapped by an outer wrapping or sleeve.
  • the frough formations are shaped to accommodate at least two rod-like articles. More preferably, in the case of a four-sided package, first and third trough formations are shaped to accommodate two articles in a side-by-side configuration, and second and fourth trough formations are shaped to accommodate three articles in a triangular stacked configuration.
  • first and third trough formations may be shaped to accommodate five articles in a 3:2 stacked configuration
  • second and fourth trough formations may be shaped to accommodate six articles in a 3:2:1 stacked configuration.
  • a six-sided package may be provided with each of the six trough fonriations being shaped to accommodate three articles in a stacked configuration.
  • the fold lines may constitute lines of weakness by being scored or perforated for allowing the selective removal of individual sub-strays.
  • the invention extends to a smoking article pack comprising a blister pack with two to ten smoking articles such as a cigar or cigarette being accommodated in each trough.
  • the invention extends to a smoking article package comprising a self supporting tray formed of a thermo-plastic material defining an elongate trough formation containing an array of between two and ten smoking articles, said trough formation being contiguous with and surrounded by a planar land, and a peelable or rupturable backing film laminated to said planar land so as to encapsulate said array of smoking articles in said trough formation, said array of smoking articles being accessible by pturing or peeling away the backing film from the tray.
  • the smoking articles are typically in a nested configuration within each trough formation and, in the case of a multi-layer array, the articles preferably progressively decrease by one from a base layer upwards.
  • the backing film may be laminated to the lands by any bonding method, such as gluing or heat sealing, as well as by a co-extrusion process.
  • a resealable adhesive may be used for bonding to enable individual smoking articles to be removed from a sub-tray, and the backing film resealed to the blister tray.

  • a blister pack 10 comprises a transparent blister tray 12 which is vacuum formed from a sheet of clear PNC having a thickness of between about 180 and 250 microns.
  • the blister tray 12 defines a plurality of trough formations 14.1 to 14.5 which are dimensioned to accommodate an array of three conventional cigarettes 16 each having a length of 85 mm and a diameter of 8 mm, with opposed ends of the cigarette abutting opposed planar end faces 18 and 20 of each trough formation so as to prevent particles of tobacco from being dislodged from the tip of each cigarette.

  • the clear Bynel layer allows for printing of further health warnings on the reverse side of the polyester.
  • This construction may be further enhanced with a metallised layer of polyester that improves the moisture barrier and further allows for high quality print of health warning on both sides of the lidding.
  • An adhesive may be further applied to facilitate the reclosure of the pack after peeling.
  • a lower cost construction includes a base web of a low cost thermoformable film or roll stock material using a non-stretch multilayered construction of nylon and polyethylene, such as a 50 micron material supplied by Astrapak Barrier Films Division in Benoni, South Africa.
  • the top or cover web may include a non-stretch film or roll stock material using a 12 micron polyester laminated to a 40 micron Bynet® sealant layer for a peelable lidding to the base web.
  • a series of parallel perforations 28 are formed through both the planar land zones 22 of the blister tray and the film 24. The perforations 28 are exactly midway between and parallel to the adjacent troughs, and are perpendicular to the side edges 30 and 32 of the blister pack.
  • FIG. 3A an underside perspective detail of an alternative embodiment is shown in which the planar land 24 is formed with a recessed rib 38 adjacent the edge of the blister pack and defining a space 40 providing access to the film for allowing it to be peeled away from the blister tray.

  • the resultant structure of the closed blister pack 44 is relatively compact and rigid. Further, it provides a number of different options for accessing cigarettes. As a first option, the overall integrity of the blister pack 44 may be retained, and laminated strips of film 76 may be selectively removed so as to gain access to the cigarettes within the trough.
  • the entire pack may be opened and disassembled either by separating the marginal flaps from one another, by tearing the pack along the perforated lines 56 and 58, or along the perforated hinge lines 50 and 52. If the pack is torn along both the marginal perforated lines 56 and 58 and the perforated hinge lines 50 and 52, then the two blister trays 46 and 48 are completely separated into separate rows, as per the Figure 1 embodiment. Cigarettes can then be distributed either singly or in groups by selectively tearing along the perforated lines 28.
  • the blister pack 44 may be enclosed by means of a sleeve having the form of an open-ended rectangular cylinder.

  • blister packs 10 of the type illustrated in Figure 1 may then be laid over the exposed troughed surfaces so as to achieve a double layer.
  • a rupturable film may also be used as a backing film. This may be in the form of a 12 to 30 micron hard aluminium foil film of the type manufactured by Alusuisse.
  • the film is lacquer coated on its operatively inner side to enable it to be laminated to the lands of the blister fray.
  • the opposite exposed face of the metallic film or foil is able to receive printing for advertising purposes.
  • a rupturable film of this type is sufficiently strong and flexible to ensure that the cigarettes are maintained within the blister pack, while at the same time being able to rapture relatively easily by pressure of the cigarette caused by finger pressure on the opposite side of the deformable trough, without deforming the cigarette unduly.

  • the result is that when the troughs of the overlying pack are pressed fully into the trough receiving recesses in the tray below a snug fit between the two layers is achieved thereby ensuring that there is a minimum of waste of space in the finished pack. It is important that wasted space is minimised for bulk packaging of smoking articles since any wasted space will decrease the bulk density of the packaged articles leading to an increase in transport and storage costs.
  • Figures 9 to 13 show a series of different configurations of arrays, but it will be understood that other arrangements are also possible. It is considered important that the trays are relatively robust to allow for the shearing of the individual packages from the tray, so the preferred configurations are an optimisation of space efficiency, manufacturing simplicity, packaging simplicity, and structural integrity.
