Definitions
- the present invention relates to packs for smoking articles such as cigarettes.
- Conventional hinged lid packs for smoking articles are made from paper card and consist of a box comprising a body and, a lid hinged to the body and an inner frame inside the body.
- the inner frame provides a surface which is overlain by an inner surface of the lid when the lid is in the closed position.
- Packs should be resistant to forces which act to distort the shape of the pack when it is in normal use, otherwise the contents of the pack may become damaged. While it is desired to reduce the amount of paper card used in packs, it is important that any reduction does not compromise the ability of the packs to protect their contents.
- a hinged lid pack for smoking articles comprising a box, the box comprising a body and a lid hinged to the body, and the pack further comprising an inner frame, wherein the inner frame is corrugated.
- a hinged lid pack for smoking articles comprising a box, the box comprising a body and a lid hinged to the body, at least one of the body and the lid being of corrugated sheet material.
- the pack further comprises an inner frame.
- a hinged lid pack for smoking articles comprising a box, the box comprising a body and a lid hinged to the body, wherein a hinge-end portion of the front and side walls of the body is indented to displace inwardly a surface which is overlain by an inner surface of the lid when the lid is in the closed position.
- Packs for smoking articles made according to the first and second aspects of the invention can be made from lower basis weight material than that conventionally used for packs while being similarly resistant to distorting forces. Packs according to the first and second aspects of the invention made of conventional basis weight card are stronger than conventional packs. It has also been found that packs for smoking articles made according to the invention have a particularly attractive appearance.
- a cut is made towards the front of the side walls of the inner frame in a direction substantially parallel to the longitudinal axis of the pack. These cuts extend, at each end, into the front wall of the inner frame to define a pair of closure tabs which project outwards from the front wall of the inner frame.
- the closure tabs have the advantage that they form an interference fit with an inner surface of the lid of the pack when it is in the closed position and help to keep the lid closed.
- the closure tabs become mis-shaped after the pack lid has been opened and closed several times and are no longer effective in maintaining the lid in the closed position.
- Closure tabs similar to conventional closure tabs in packs according to the first aspect of the invention, in which the corrugations extend transversely across the closure tabs, have been found to be stronger and thus more resistant to the effects of continual opening and closing of the pack lid than conventional closure tabs.
- Packs according to the third aspect of the invention do not require an inner frame, cutting down on the weight and cost of the packs.
- the hinged lid cigarette pack 10 of Figure 1 comprises a box 12'comprising a body 14, and a lid 16 hinged to the body.
- the pack also includes an inner frame 18.
- the inner frame 18 is formed with corrugations 20 substantially transverse to the longitudinal axis of the cigarette pack 10.
- the cigarette pack 30 of Figure 2 also according to the first aspect of the invention comprises a box 32 comprising a body 34 and a hinged lid 36.
- the pack also includes an inner frame 38.
- the inner frame 38 is formed with corrugations 40 substantially parallel to the longitudinal axis of the cigarette pack 30.
- the corrugations may extend only across the front wall of the inner - frame, or only across the side walls of the inner frame.
- the cigarette pack 50 of Figure 3 comprises a box 52 comprising a body 54, a hinged lid 56.
- the pack also includes an inner frame 58.
- the front and side walls of the body 54 are formed with corrugations 60 substantially transverse to the longitudinal axis of the cigarette pack 50.
- the cigarette pack 70 of Figure 4 also according to the second aspect of the invention, comprises a box 72 comprising a body 74 and a hinged lid 76.
- the pack also includes an inner frame 78.
- the front and side walls of the body 74 are formed with corrugations 80 substantially parallel to the longitudinal axis of the cigarette pack 70.
- the cigarette pack 90 of Figure 5 comprises a box 92 comprising a body 94 and a hinged lid 96.
- the pack also includes an inner frame 98.
- the front wall of the body 94 is formed with corrugations 100 which diverge from each other as they extend generally transversely across the front wall of the pack body.
- the corrugations may extend only across the front or rear wall of the body, or only across the side walls of the body of the pack.
- the corrugations may extend over all or a part of the lid and/or the body of the pack.
- Packs according to the invention in which the corrugations extend across a fold which defines a corner of the pack in a direction substantially transverse to the corner have been found to be particularly resistant to distorting forces.
- the corrugations may extend only across a fold which defines a corner of the pack in a direction substantially transverse-to the corner.
- the cigarette pack 110 of Figure 6 comprises a box 112 comprising a body 114 and a hinged lid 116.
- the front wall 118 and the side walls 120 of the body 114 are indented along a line 122 across the hinge end portion of the walls to define a closing surface 124 which is overlain by the inner surface of the lid 116 when the lid is in the closed position. It will be seen that the appearance and, in part, the function of the closing surface 122 is equivalent to that of a conventional inner frame.
- each trough or between each ridge is preferably between 0.5mm and 4mm.
- the height from trough to peak of each ridge is preferably between 0.1mm and 2.0mm.
- the troughs and ridges may follow any path, such as a straight line and can extend across the box or inner frame at any angle. At least two lines of corrugations may meet to form a chevron.
- the corrugations may extend over all or a part of the inner frame or the box.
- the cross sectional profile of the corrugations may follow any desired shape, such as a sine wave or a sawtooth profile.
- the troughs of the corrugations may be flattened so that the regions of the corrugated part of the pack which come into contact with the contents of the pack are substantially flat.
- Such types of corrugations have been found to have the advantage that the contents of the pack are not damaged if the corrugated material is pressed against them, for example when the pack is squashed.
- the apparatus of Figure 7 for corrugating sheet material used in packs according to the invention comprises a first 210 and second 212 right-cylindrical roller of circular cross section, having the same diameters and lengths as each other.
- the rollers 210 and 212 are rotatable about their longitudinal axes 214,216 (referred to as axes of rotation below).
- the curved surfaces 218,222 of the rollers have corrugations 220,224 substantially parallel to the axes of rotation of the rollers.
- the first roller 210 is disposed above the second roller 212 so that the axis of rotation 214 of the first roller is vertically above and parallel to the axis of rotation 216 of the second roller. Just sufficient space is left between the rollers 210,212 for a sheet 226 of card to pass between them.
- the roller 210 is rotated- clockwise about its axis of rotation 214 and the roller 212 is rotated anticlockwise about its axis of rotation 216.
- the rollers 210,212 rotate past each other, the troughs of the corrugations 220 on the first roller mesh with the ridges of the corrugations 224 on the second roller in the nip between the rollers.
- the sheet 226 of card is fed into the nip; as it passes between the rollers, the corrugations 220 of the first roller 210 contact one surface of the sheet 226 and the corrugations 224 of the second roller 212 contact the other surface of the sheet 226; the sheet 226 is thereby corrugated.
- the direction in which the sheet 226 is corrugated may be altered simply by feeding the sheet between the rollers at a different angle to that shown in figure 7.
- sheet material to be corrugated is stored as a reel. When material is required, it is unwound from the reel and fed into the nip between the rollers. Corrugated material is cut to the correct size as it emerges from the rollers before being fed into a packaging machine that assembles packs according to the invention. Alternatively, the sheet material may be cut to the correct size before it is fed between the rollers.
- This method can be used for corrugating material of the inner frame and also for corrugating any part of the pack. It has been found that the sheet material is more easily cut if the corrugations do not extend into the region of the material that is cut. When the corrugations do not extend into these regions, it will be noted that the margins of the corrugated material are not corrugated. Alternatively, if the corrugations do extend into the region of the material that is cut, it has been found that cutting is greatly facilitated if the corrugated material immediately adjacent the cut is supported on a surface which has corrugations similar to those of the material.
- the rollers may be of different diameter and/or- length and/or shape to that described and of different diameter and/or length and/or shape to one another.
- the arrangement of the rollers may be different to that described.
- the axis of rotation of the upper roller may not be vertically above the axis of rotation of the other roller, but instead at an angle.
- the rollers may move relative to a stationary sheet so that their axes of rotation traverse the length of the sheet.
- the corrugations of the curved surface of each cylindrical roller need not be exactly as those described in this embodiment.
- the height from trough to peak of the corrugations is preferably between 0.1mm and 2mm and the width of the corrugations is preferably between 0.5 and 4mm.
- the corrugations can have any profile in cross section, such as a sine wave or a saw-tooth profile.
- the troughs or the ridges of the corrugations may be substantially flattened.
- the corrugations may be in any direction relative to the rollers, such as substantially transverse to the respective axes of rotation of the rollers.
- the corrugations may extend over all or a part of the curved surface of the rollers.
- the material is positioned relative to the corrugations on the rollers so that the material is corrugated and then, if necessary, subsequently cut.
- corrugations are formed in a direction substantially parallel to the longitudinal axis of the pack using rollers comprising curved surfaces that are corrugated in a direction substantially perpendicular to the axes of rotation of the rollers, the material is positioned correctly relative to the rollers and to the cutting apparatus (when used).
- the rotation of the rollers must be synchronised with the passage of the material when the material is pre-cut to the correct size and also with the cutting apparatus, when the material is cut to the correct size after it has been corrugated, to allow the corrugations of the inner frame to be positioned correctly.
- transverse corrugations are formed using rollers with curved surfaces that are corrugated in a direction substantially parallel to the axes of rotation of the rollers
- the rotation of the rollers must be synchronised with the passage of the material, when the material is pre-cut to the correct size, and with the cutting apparatus, when the material is cut to the correct size, after it has been corrugated, to allow the corrugations of the inner frame to be positioned correctly.
- transverse corrugations are formed using rollers with curved surfaces that are corrugated in a direction substantially transverse to the axes of rotation of the rollers, the material is positioned correctly relative to the rollers and to the cutting-apparatus (when used).

- the corrugated rollers 312, 314, and the closure tab cutting rollers 310 are each attached at one end to respective spur gears 318, 320, 322, 324.
- the central axis of each gear is aligned with-the axis of rotation of the roller it is attached to.
- a central spur gear 326 is disposed between the spur gears 320, 324 at the ends of the two lower rollers.

- Adjustment of the rollers on their shafts allows the exact position of the troughs and ridges of the corrugated rollers to be altered relative to the angular position of the closure tab cutting rollers 310 and the position of the cutting blade 316. This allows the position of corrugations on the cut inner frame to be precisely determined.
- a similar mechanism of adjustment may be used to alter the angular position of the closure tab cutting rollers 310, allowing the precise position of the cuts defining the closure tabs of the inner frame to be determined.

- the material between them is itself corrugated.
- This method can be used to corrugate precut blanks of material which are, subsequently folded to form the pack lid and body according to the invention by the packaging apparatus; it can also be used to corrugate the material of the inner frame.
- Packs for smoking articles according to the first and second aspects of the invention can be made from thinner material than that used to make conventional packs, without compromising the ability of the packs to resist distorting forces that are encountered in normal use. Such packs also have the advantage that the material used to make them is more easily retained in a folded position than conventional packs. Consequently, the number of gluing points required when the packs are made are reduced. Packs according to the third aspect of the invention do not require an inner frame.
Abstract
Description
- The present invention relates to packs for smoking articles such as cigarettes.
- Conventional hinged lid packs for smoking articles are made from paper card and consist of a box comprising a body and, a lid hinged to the body and an inner frame inside the body. The inner frame provides a surface which is overlain by an inner surface of the lid when the lid is in the closed position. Packs should be resistant to forces which act to distort the shape of the pack when it is in normal use, otherwise the contents of the pack may become damaged. While it is desired to reduce the amount of paper card used in packs, it is important that any reduction does not compromise the ability of the packs to protect their contents.
- According to a first aspect of the invention there is provided a hinged lid pack for smoking articles comprising a box, the box comprising a body and a lid hinged to the body, and the pack further comprising an inner frame, wherein the inner frame is corrugated.
- According to a second aspect of the invention there is provided a hinged lid pack for smoking articles comprising a box, the box comprising a body and a lid hinged to the body, at least one of the body and the lid being of corrugated sheet material. Preferably the pack further comprises an inner frame.
- According to a third aspect of the invention there is provided a hinged lid pack for smoking articles comprising a box, the box comprising a body and a lid hinged to the body, wherein a hinge-end portion of the front and side walls of the body is indented to displace inwardly a surface which is overlain by an inner surface of the lid when the lid is in the closed position.
- According to the invention there is also provided a method and apparatus for corrugating material used in packs according to the invention.
- Packs for smoking articles made according to the first and second aspects of the invention can be made from lower basis weight material than that conventionally used for packs while being similarly resistant to distorting forces. Packs according to the first and second aspects of the invention made of conventional basis weight card are stronger than conventional packs. It has also been found that packs for smoking articles made according to the invention have a particularly attractive appearance.
- In conventional hinged lid packs for smoking articles, a cut is made towards the front of the side walls of the inner frame in a direction substantially parallel to the longitudinal axis of the pack. These cuts extend, at each end, into the front wall of the inner frame to define a pair of closure tabs which project outwards from the front wall of the inner frame. The closure tabs have the advantage that they form an interference fit with an inner surface of the lid of the pack when it is in the closed position and help to keep the lid closed. However, the closure tabs become mis-shaped after the pack lid has been opened and closed several times and are no longer effective in maintaining the lid in the closed position. Closure tabs similar to conventional closure tabs in packs according to the first aspect of the invention, in which the corrugations extend transversely across the closure tabs, have been found to be stronger and thus more resistant to the effects of continual opening and closing of the pack lid than conventional closure tabs.
- Packs according to the third aspect of the invention do not require an inner frame, cutting down on the weight and cost of the packs.
- The invention will be described by way of example with reference to the accompanying drawings in which:

- The hinged
lid cigarette pack 10 of Figure 1, according to the first aspect of the invention comprises a box 12'comprising abody 14, and alid 16 hinged to the body. The pack also includes aninner frame 18. Theinner frame 18 is formed withcorrugations 20 substantially transverse to the longitudinal axis of thecigarette pack 10. - The
cigarette pack 30 of Figure 2, also according to the first aspect of the invention comprises abox 32 comprising abody 34 and ahinged lid 36. The pack also includes an inner frame 38. The inner frame 38 is formed withcorrugations 40 substantially parallel to the longitudinal axis of thecigarette pack 30. In other embodiments of the first aspect of the invention, the corrugations may extend only across the front wall of the inner - frame, or only across the side walls of the inner frame. - The cigarette pack 50 of Figure 3, according to the second aspect of the invention, comprises a
box 52 comprising abody 54, ahinged lid 56. The pack also includes aninner frame 58. The front and side walls of thebody 54 are formed withcorrugations 60 substantially transverse to the longitudinal axis of the cigarette pack 50. - The
cigarette pack 70 of Figure 4, also according to the second aspect of the invention, comprises abox 72 comprising abody 74 and ahinged lid 76. The pack also includes aninner frame 78. The front and side walls of thebody 74 are formed withcorrugations 80 substantially parallel to the longitudinal axis of thecigarette pack 70. - The cigarette pack 90 of Figure 5, according to the second aspect of the invention, comprises a
box 92 comprising abody 94 and ahinged lid 96. The pack also includes an inner frame 98. The front wall of thebody 94 is formed with corrugations 100 which diverge from each other as they extend generally transversely across the front wall of the pack body. In other embodiments of the second aspect of the invention, the corrugations may extend only across the front or rear wall of the body, or only across the side walls of the body of the pack. Also according to the second aspect of the invention, the corrugations may extend over all or a part of the lid and/or the body of the pack. - Packs according to the invention in which the corrugations extend across a fold which defines a corner of the pack in a direction substantially transverse to the corner, as in the embodiments of the invention illustrated in Figures 1 and 3 have been found to be particularly resistant to distorting forces. In other embodiments of the first and second aspects of the invention, the corrugations may extend only across a fold which defines a corner of the pack in a direction substantially transverse-to the corner.
- The
cigarette pack 110 of Figure 6, according to the third aspect of the invention, comprises abox 112 comprising abody 114 and ahinged lid 116. Thefront wall 118 and the side walls 120 of thebody 114 are indented along aline 122 across the hinge end portion of the walls to define aclosing surface 124 which is overlain by the inner surface of thelid 116 when the lid is in the closed position. It will be seen that the appearance and, in part, the function of theclosing surface 122 is equivalent to that of a conventional inner frame. - It is not intended that the corrugation patterns are limited to those in the embodiments described above. The distance between each trough or between each ridge is preferably between 0.5mm and 4mm. The height from trough to peak of each ridge is preferably between 0.1mm and 2.0mm. The troughs and ridges may follow any path, such as a straight line and can extend across the box or inner frame at any angle. At least two lines of corrugations may meet to form a chevron. The corrugations may extend over all or a part of the inner frame or the box.
- The cross sectional profile of the corrugations may follow any desired shape, such as a sine wave or a sawtooth profile. The troughs of the corrugations may be flattened so that the regions of the corrugated part of the pack which come into contact with the contents of the pack are substantially flat. Such types of corrugations have been found to have the advantage that the contents of the pack are not damaged if the corrugated material is pressed against them, for example when the pack is squashed.
- The apparatus of Figure 7 for corrugating sheet material used in packs according to the invention comprises a first 210 and second 212 right-cylindrical roller of circular cross section, having the same diameters and lengths as each other. The
rollers first roller 210 is disposed above thesecond roller 212 so that the axis ofrotation 214 of the first roller is vertically above and parallel to the axis of rotation 216 of the second roller. Just sufficient space is left between the rollers 210,212 for asheet 226 of card to pass between them. - In operation, the
roller 210 is rotated- clockwise about its axis ofrotation 214 and theroller 212 is rotated anticlockwise about its axis of rotation 216. As the rollers 210,212 rotate past each other, the troughs of thecorrugations 220 on the first roller mesh with the ridges of thecorrugations 224 on the second roller in the nip between the rollers. Thesheet 226 of card is fed into the nip; as it passes between the rollers, thecorrugations 220 of thefirst roller 210 contact one surface of thesheet 226 and thecorrugations 224 of thesecond roller 212 contact the other surface of thesheet 226; thesheet 226 is thereby corrugated. It will be noted that the direction in which thesheet 226 is corrugated may be altered simply by feeding the sheet between the rollers at a different angle to that shown in figure 7. - Typically, sheet material to be corrugated is stored as a reel. When material is required, it is unwound from the reel and fed into the nip between the rollers. Corrugated material is cut to the correct size as it emerges from the rollers before being fed into a packaging machine that assembles packs according to the invention. Alternatively, the sheet material may be cut to the correct size before it is fed between the rollers. This method can be used for corrugating material of the inner frame and also for corrugating any part of the pack. It has been found that the sheet material is more easily cut if the corrugations do not extend into the region of the material that is cut. When the corrugations do not extend into these regions, it will be noted that the margins of the corrugated material are not corrugated. Alternatively, if the corrugations do extend into the region of the material that is cut, it has been found that cutting is greatly facilitated if the corrugated material immediately adjacent the cut is supported on a surface which has corrugations similar to those of the material.
- The rollers may be of different diameter and/or- length and/or shape to that described and of different diameter and/or length and/or shape to one another. The arrangement of the rollers may be different to that described. For example, the axis of rotation of the upper roller may not be vertically above the axis of rotation of the other roller, but instead at an angle. The rollers may move relative to a stationary sheet so that their axes of rotation traverse the length of the sheet.
- The corrugations of the curved surface of each cylindrical roller need not be exactly as those described in this embodiment. The height from trough to peak of the corrugations is preferably between 0.1mm and 2mm and the width of the corrugations is preferably between 0.5 and 4mm. The corrugations can have any profile in cross section, such as a sine wave or a saw-tooth profile. The troughs or the ridges of the corrugations may be substantially flattened. The corrugations may be in any direction relative to the rollers, such as substantially transverse to the respective axes of rotation of the rollers. The corrugations may extend over all or a part of the curved surface of the rollers.
- In conventional hinged lid packs, the rearmost portion of the side walls of the inner frame is angled inwards so that the upper rear corners of the inner frame do not catch on the side walls of the lid as it is closed. It will be appreciated that packs made according to certain embodiments of the first aspect of the invention in which the corrugations extend across the rearmost section of the side walls of the inner frame have the advantage that no specific folding of the inner frame is required to prevent the lid catching on the inner frame as it is closed. In these embodiments it can be ensured that when the material of the inner frame is corrugated and subsequently cut, the corrugations are disposed over the regions of the material that will form the rearmost part of the side walls of the inner frame such that the upper rear corners of the inner frame curve inwards when the packs are assembled. To achieve this using corrugating rollers, the material is positioned relative to the corrugations on the rollers so that the material is corrugated and then, if necessary, subsequently cut. When corrugations are formed in a direction substantially parallel to the longitudinal axis of the pack using rollers comprising curved surfaces that are corrugated in a direction substantially perpendicular to the axes of rotation of the rollers, the material is positioned correctly relative to the rollers and to the cutting apparatus (when used). When the longitudinal corrugations are formed using rollers with curved surfaces that are corrugated in a direction substantially parallel to the axes of rotation of the rollers, the rotation of the rollers must be synchronised with the passage of the material when the material is pre-cut to the correct size and also with the cutting apparatus, when the material is cut to the correct size after it has been corrugated, to allow the corrugations of the inner frame to be positioned correctly.
- Similarly, when transverse corrugations are formed using rollers with curved surfaces that are corrugated in a direction substantially parallel to the axes of rotation of the rollers, the rotation of the rollers must be synchronised with the passage of the material, when the material is pre-cut to the correct size, and with the cutting apparatus, when the material is cut to the correct size, after it has been corrugated, to allow the corrugations of the inner frame to be positioned correctly. When transverse corrugations are formed using rollers with curved surfaces that are corrugated in a direction substantially transverse to the axes of rotation of the rollers, the material is positioned correctly relative to the rollers and to the cutting-apparatus (when used).
- Figure 8 is a schematic view of an apparatus for adjusting the position of corrugations on the inner frame. Conventional ' cigarette packing apparatus includes machinery for cutting inner frames from a strip of card off a reel. This machinery includes, upstream of the cutter, apparatus for cutting from the inner frame, the closure tabs which retain the lid shut. This apparatus which is of known construction, and operation is shown schematically at 310 in figure 8, and comprises upper and lower rollers. The card from the reel passes through the nip between the rollers. According to the invention, upper 312 and lower 314 adjacent corrugated rollers are provided immediately downstream of the closure
tab cutting rollers 310 between the tab cutting rollers and theblade 316 which cuts the inner frame from the strip of card. Thecorrugated rollers tab cutting rollers 310 are each attached at one end to respective spur gears 318, 320, 322, 324. The central axis of each gear is aligned with-the axis of rotation of the roller it is attached to. Acentral spur gear 326 is disposed between the spur gears 320, 324 at the ends of the two lower rollers. Thegears corrugated roller 314 is driven, and drives the upper corrugated roller and, through thecentral spur gear 326, the closure tab cutting rollers. A series of conventional gear linkages (not shown) connect the cutting apparatus to the drivenspur gear 320 at the end of the lowercorrugated roller 314. As the two pairs of rollers are rotated, the strip of card (not shown) used to make inner frames is fed into the nip between the closuretab cutting rollers 310. The sheet then passes into the nip between thecorrugating rollers cutting blade 316, which cuts the inner frames from the strip. The inner frames are then assembled into a pack for smoking articles according to the invention. - The conventional gear linkages between the
gear 320 at the end of the lowercorrugated roller 314 and thecutting blade 316 ensure that the action of the cutting blade is synchronised with the tab cutting and corrugating actions. Thus, the closure tabs and the corrugations are positioned correctly on the cut inner frames. - The relative positioning of the components of the apparatus may be altered so that the cuts defining the closure tabs of the inner frame, the corrugations, and the sizing cut are formed in a different order. For example, the sheet may be cut to the size of the inner frame after the cuts defining the closure tabs are made, but before the sheet is corrugated. The gear linkages are adjusted appropriately so that synchronisation is maintained.
- The positioning of corrugations and/or closure tabdefining cuts formed on the inner frame may be altered by disengaging the gears at the end of the rollers, rotating the rollers, theri re-engaging the gears. The precision of the adjustment that can be made, however, is dependent on the pitch of the gears. A further aspect of the apparatus described above is that the position of the corrugated
rollers corrugated roller 314. Figure 10 shows a detailed perspective view of one end of the lowercorrugated roller 314. In both figures 9 and 10, the spur gears on the roller are omitted. Theroller 314 is hollow and has acylindrical shaft 328 running through its centre. Theshaft 328 is long enough to project from either end of theroller 314 and carries the spur gear (not shown). The roller can be rotated relative to the shaft. The roller is fixed to the shaft at each end by respectiveopen rings Screws respective rings ring respective screws screws open rings open ring roller 314. Part of one side of oneopen ring 330 is attached to one end of theroller 314. The region of the side of theopen ring 330 adjacent to the open ends of the ring is not attached to the end of the roller so that the open ends of the ring can move relative to one another. The otheropen ring 332 is similarly attached to the other end of theroller 314. Theshaft 328 passes, through theopen rings shaft 328 by tightening thescrews open rings roller 314 relative to theshaft 328 can be adjusted manually by undoing the screws so that the internal diameter of the open rings is increased and the roller is free to be rotated relative to the shaft. Theupper roller 312 is adjusted on a shaft in an identical manner. - Adjustment of the rollers on their shafts allows the exact position of the troughs and ridges of the corrugated rollers to be altered relative to the angular position of the closure
tab cutting rollers 310 and the position of thecutting blade 316. This allows the position of corrugations on the cut inner frame to be precisely determined. A similar mechanism of adjustment may be used to alter the angular position of the closuretab cutting rollers 310, allowing the precise position of the cuts defining the closure tabs of the inner frame to be determined. - In an alternative method by which sheet material used in packs according to the invention is corrugated, the material is placed on top of a corrugated surface. Another corrugated surface is then placed on top of the material. The corrugations of the lower corrugated surface mesh with the corrugations of the upper corrugated surface. As the two corrugated surfaces come together, the material between them is itself corrugated. This method can be used to corrugate precut blanks of material which are, subsequently folded to form the pack lid and body according to the invention by the packaging apparatus; it can also be used to corrugate the material of the inner frame.
- Packs for smoking articles according to the first and second aspects of the invention can be made from thinner material than that used to make conventional packs, without compromising the ability of the packs to resist distorting forces that are encountered in normal use. Such packs also have the advantage that the material used to make them is more easily retained in a folded position than conventional packs. Consequently, the number of gluing points required when the packs are made are reduced. Packs according to the third aspect of the invention do not require an inner frame.
- It will be appreciated that the types of corrugations described above may be applied to other types of packs than those described. For example, oval packs and blanked corner packs. They may be applied to one, some, or all corners, rounded edges, bevelled edges, or other types of edges. Various aspects of the invention are defined in the numbered paragraphs that follow:
