Definitions

  • the present invention relates to a container for consumer goods and to a blank for forming such container, which find particular application for holding elongate consumer goods, such as smoking articles (for example cigarettes).
  • Elongate aerosol-generating articles such as cigarettes and cigars
  • hinge-lid packs having a box for housing the aerosol-generating articles and a lid connected to the box about a hinge line extending across the back wall of the container.
  • the front and side walls of the box typically abut the corresponding front and side walls of the lid when the lid is closed.
  • the hinge-lid pack may also comprise an inner frame secured to an inner surface of the box, the inner frame having front and side walls against which the lid closes.
  • Such packs are typically constructed from laminar cardboard blanks.
  • the lid In use, the lid is pivoted about the hinge line to open the pack and so gain access to the aerosol-generating articles held in the box.
  • the hinge line across the back wall of the container is higher than the line of abutment between the front wall of the box and the front wall of the lid.
  • the line of abutment between the box and lid side walls typically slopes diagonally downwards from the back of the container to the front.
  • the opening of such containers can be made even more difficult, if the container is provided with means for ensuring that the lid remains firmly shut in the closed position, when the container is not being used or handled.
  • Such means can include retention cuts on inner frames, adhesive on the inner surface of the lid or outer surface of the inner frame, and hook and latch mechanisms.
  • WO 2013/179418 A1 discloses a hinge-lid container that is wrapped in an outer film, which has a tear tape that a consumer pulls in order to remove the film and access the smoking articles.
  • a corner portion of the box is modified to have a "grip-facilitating section" in the form of a notch, opening or indentation. It would therefore be desirable to provide a container that can still remain firmly shut when not in use, but which can then be easily opened by a consumer. It would also be desirable to provide a container that could be opened by a consumer using only one hand. It would also be desirable to provide a container that could be opened without relying on frictional force between the surfaces of the lid and the consumer's fingers. It would also be desirable to provide a blank for manufacturing such containers, which does not require any major modification of existing packing apparatus, or use of complex additional components.
  • a container for consumer articles comprising: a box comprising a box front wall, a box back wall, a box bottom wall, and first and second box side walls; and a lid comprising a lid front wall, a lid back wall, a lid top wall, and first and second lid side walls.
  • a lower edge of the lid back wall depends along a hinge line from a top edge of the box back wall, with the lid being moveable about the hinge line between an open position and a closed position, in which at least a portion of the lower edge of the first lid side wall abuts at least a portion of the upper edge of the first box side wall, and in which at least a portion of the lower edge of the lid front wall abuts at least a portion of the upper edge of the box front wall.
  • the first box side wall is connected to the box front wall by a first box edge portion
  • the first lid side wall is connected to the lid front wall by a first lid edge portion
  • the shape of the first lid edge portion is different from the shape of the first box edge portion, such that, when the lid is in the closed position, the lower edge of the first lid edge portion is disposed beyond the upper edge of the first box edge portion in a transverse direction of the container.
  • the present invention relates to a container having a lid comprising a first lid edge portion having a shape that is different from the shape of a corresponding first box edge portion, such that, when the lid is in the closed position, the lower edge of the first lid edge portion is disposed beyond the upper edge of the first box edge portion in a transverse direction of the container.
  • This creates a transverse space or gap between the lower edge of the lid and the upper edge of the box, when the lid is in the closed position. Consequently, a consumer can simply push directly upwards on the lid by engaging a finger with the exposed lower lid edge, and thereby cause the lid to pivot about the hinge line to the open position.
  • This action can be applied by using only one finger, such as a thumb, and thereby allows a consumer to hold the container in one hand and open the container with said single hand. Furthermore, this action does not need to rely on frictional force between a consumer's finger and the lid in order to transfer a pivoting force to the lid, and consequently can be easier for a consumer to apply. That is, because the consumer is applying an upwards force directly to an edge of the lid, there is no need to rely on frictional force between the lid's surface and the consumer's finger(s), and therefore the container can be opened more easily by the consumer.
  • the first box edge portion may have any suitable shape that could ensure that the lower edge of the first lid edge portion is disposed beyond the upper edge of the first box edge portion in a transverse direction of the container.
  • the first box edge portion extends from the upper edge of the box to the box bottom wall. In such embodiments, the first box edge portion completely separates the box front wall from the first box side wall.
  • the first box edge portion comprises a bevelled or curved shape.
  • the bevelled or curved shape extends from the upper edge of the box to the box bottom wall.
  • the first box edge portion comprises a substantially triangular shape, wherein one side of the substantially triangular shape forms the upper edge of the first box edge portion.
  • the remaining two sides of the substantially triangular shape may respectively extend from opposed ends of the upper edge of the first box edge portion and converge and terminate at an intersection point below the upper edge of the first box edge portion.
  • Each of the remaining two sides of the substantially triangular shape may follow a straight trajectory or a curved trajectory as they extend towards the intersection point.
  • the substantially triangular shape may extend from the upper edge of the box to the box bottom wall. However, in some preferred embodiments, the substantially triangular shape terminates above the box bottom wall.
  • Providing a substantially triangular shape on the first box edge portion can be particularly advantageous as it can allow the container to exhibit the easy-lift function described above, without necessarily requiring the lid top wall to have different dimensions to the box bottom wall. This means that the overall maximum transverse dimensions of the container do not necessarily need to be adjusted in order to accommodate the easy-lift function described above. Consequently, the container can be manufactured, transported and handled without significantly altering existing machinery, storage equipment, handling apparatus, processes, or any combination thereof.
  • the width and length of the box bottom wall is substantially the same as the width and length of the lid top wall.
  • This can allow the container to exhibit the easy-lift function described above, whilst still having the same cross- section when viewed from above as that when viewed from below.
  • the container may therefore exhibit the easy-lift function described above, without altering other dimensional aspects of the container that may generally be considered aesthetically desirable for containers for consumer goods, such as smoking articles.
  • the maximum length and width of the container are substantially the same as the width and length of the box bottom wall and the width and length of the lid top wall.
  • the shape of the first lid edge portion is different from the shape of the first box edge portion, such that, when the lid is in the closed position, the lower edge of the first lid edge portion is disposed beyond the upper edge of the first box edge portion in a transverse direction of the container. Consequently, the upper edge of the first box edge portion has a length that is greater than the length of the lower edge of the first lid edge portion.
  • the upper edge of the first box edge portion has a length of at least two times the length of the lower edge of the first lid edge portion, even more preferably of at least four times the length of the lower edge of the first lid edge portion. This can result in a suitably sized space between the lower edge of the first lid edge portion and the upper edge of the first box edge portion in a transverse direction of the container.
  • the container may be formed from any suitable material or combination of materials.
  • the box and lid of the container are at least partially formed from a folded laminar blank, more preferably a cellulose-fiber-based laminar blank.
  • the shape of the first lid edge portion and the shape of the first box edge portion are each defined by one or more respective lines of weakness in the laminar blank. This can allow the container and the shapes of the first lid edge portion and first box edge portion to be manufactured using existing equipment and process, such as the equipment and processes typically used for manufacturing containers for smoking articles.
  • the first lid edge portion is defined by a single line of weakness extending in a longitudinal direction of the container between the first lid side wall and the lid front wall. This can result in the first lid edge portion having a square edge profile when viewed from the top the container. That is, the first lid edge portion may form a single line that defines a substantially 90 degrees turning point between the lid front wall and the first lid side wall.
  • the laminar blank preferably comprises two or more lines of weakness that defines the first box edge portion.
  • the laminar blank comprises two or more such lines that extend in parallel from the upper edge of the first box edge portion to the box bottom wall.
  • the first box edge portion comprises a substantially bevelled or curved shape. The number of such parallel lines and relative spacing between such parallel lines will influence whether the first box edge portion comprises a substantially bevelled or curved shape.
  • the first box edge portion comprises an upper section defined by two lines of weakness extending from the upper edge of the first box edge portion towards the box bottom wall and tapering towards one another, and a lower section defined by one or more lines of weakness extending from the lower end of the upper section towards the box bottom wall, preferably terminating at or about the box bottom wall.
  • the upper section of the first box edge portion preferably defines a substantially triangular shape.
  • the lower section of the first box edge portion may define a bevelled shape, a curved shape, or a single substantially 90 degrees turning point between the box front wall and the first box side wall.
  • the lower section of the first box edge portion comprises a single line of weakness that defines a single substantially 90 degrees turning point between the box front wall and the first box side wall.
  • this single line of weakness extends from the box bottom wall to the lower end of the upper section of the first box edge portion.
  • This arrangement is particularly preferably as it requires a minimal amount of lines of weakness in order to form the required shape for the first box edge portion, whilst also allowing for the maximum width and length of the container to be defined by the width and length of the box bottom wall and the width and length of the lid top wall.
  • the one or more lines of weakness that define the shape of the first box edge portion and the shape of the first lid edge portion may be formed as creasing lines in the laminar blank. That is, the one or more lines of weakness may be formed by applying mechanical deformation at select locations on the laminar blank.
  • the one or more lines of weakness are defined by one or more ablated lines on the inner surface of the laminar blank.
  • This can allow containers according to the present invention to be formed on existing high speed manufacturing machines with minimal modification.
  • the specially selected shapes of the first lid edge portion and the first box edge portion are formed automatically by virtue of the normal folding forces that are applied to the blank during manufacture of the container. That is, folding the blank about its normal fold lines to create the walls of the container automatically deforms the blank along the ablated lines that define the shapes of the first lid edge portion and the first box edge portion, so that no further processes are required to form these specially selected shapes.
  • the laminar blank can be adapted easily to form containers having the required shapes of the first lid edge portion and the first box edge portion, without the need for major modifications of the packing machine used to assemble and pack the container.
  • forming the ablated lines by removing material from the surface of the blank that forms an inner surface of the container advantageously maintains a smooth outer surface of the container, which may provide a desirable appearance of the container upon visual and tactile inspection.
  • each ablated line preferably has a minimum residual thickness (RT) of at least about 5 percent, more preferably at least about 10 percent, more preferably at least about 15 percent, more preferably at least about 20 percent, more preferably at least about 25 percent and even more preferably at least about 30 percent of the thickness (T) of the blank.
  • each ablated line preferably has a residual thickness of less than about 50 percent, more preferably less than about 45 percent and even more preferably less than about 40 percent of the thickness (T) of the blank.
  • the present inventors have found that, if the ablated line extends too far into the thickness of the laminar blank (that is, too deep) then the resultant outer surface of the container can be undesirably affected. For example, the outer surface can appear cracked or broken. Furthermore, the present inventors have found that, if an ablated line does not extend far enough into the thickness of the laminar blank (that is, too shallow) then the resultant outer surface of the container can also be undesirably affected. In particular, the present inventors have found that the turning points of the container along the ablated lines may be poorly defined on the container outer surface, and/or may follow an unintended trajectory along the outer surface of the container.
  • an ablated line extends in a straight line along the inner surface of the container
  • the present inventors have found that the corresponding turning point that is produced on the outer surface of the container may be non-linear, or uneven.
  • the present inventors have therefore identified that a cleaner looking, more well- defined container can be produced when each of the ablated lines has a residual thickness as specified above.

  • Containers according to the present invention are preferably parallelepipedal in shape, with the box front wall, box back wall, box bottom wall, first and second box side walls, lid front wall, lid back wall, lid top wall, and first and second lid side walls forming the major walls of the parallelepipedal container.
  • edge portion is used herein to refer to the portion of the blank defining an edge between two adjacent walls of the container.
  • a "cellulose-fiber-based laminar blank” is used herein to refer to a laminar blank comprising at least 50 percent by weight of cellulose fibers, based on the total fiber content of the laminar blank.
  • the cellulose-fiber-based laminar blank of the invention may include other types of fibers, such as polymer fibers.
  • inner surface is used throughout the specification to refer to the side of a portion of the blank that, once the container is assembled, faces towards the interior of the container, for example towards the consumer goods, when the container is closed. Thus, the inner surface is not directly visible for the consumer when the container is closed.
  • outer surface is used throughout the specification to refer to the side of a portion of the blank that, once the container is assembled, faces towards the exterior of the container.
  • ablated line is used herein to refer to a line along the inner surface of the edge portion from which material has been ablated (for example, removed by means of a laser beam or a blade). Accordingly, the residual thickness of an ablated line is less than the thickness (T) of the laminar blank.
  • the ablated line is preferably provided as a groove within the blank. This may be formed with a linear ablation tool, such as a laser or a blade.
  • the "thickness" (T) of the blank is the thickness of the blank after it has been manufactured, but before any ablation lines or creasing lines have been formed in the blank. That is, the thickness (T) of the blank is the thickness in any region of the blank not containing an ablated line or a crease line.
  • residual thickness is used herein to refer to the minimum distance measured between two opposite surfaces of the laminar blank or of a wall of the container formed from the blank. In practice, the distance at a given location is measured along a direction locally perpendicular to the opposite surfaces.
  • the residual thickness of the ablated line may vary across a width of the ablated line, (e.g. V-shaped, U-shaped grooves).
  • minimum residual thickness is used herein to refer to the smallest value of “residual thickness” measured in an ablated line at a given location.
  • the residual thickness of each ablated line can be determined by using an Optical Profilometer for 2D Non-Contact Surface Metrology, such as the MicroSpy (RTM) Profile (commercially available from Fries Research & Technology GmbH, Bergisch Gladbach, Germany), or a 3D laser scanning confocal microscope, such as the VK-X series of microscopes (commercially available from Keyence Corporation of America, New Jersey, United States of America).
  • RTM MicroSpy
  • VK-X series of microscopes commercially available from Keyence Corporation of America, New Jersey, United States of America.
  • the residual thickness is measured at both ends of the ablated line and at three further points distanced 20 millimetres, forty millimetres and sixty millimetres respectively from one end of the ablated line, preferably from the lower end of the ablated line.
  • residual stiffness is used to describe the stiffness of the residing laminar blank as measured over the minimum residual thickness of one given ablation line and is calculated using the stiffness in bending direction of the laminar blank multiplied by the percentage of residual thickness. For example, if the stiffness in the bending direction of the non-ablated laminar blank is 100 milliNewton and the minimum residual thickness is 30 percent, then the residual stiffness in bending direction is 100 milliNewton multiplied by thirty percent equal 30 milliNewton.
  • the stiffness of the laminar blank can be measured in accordance with ISO 2493, 15 degrees, for example by taking a sample of the blank material from a portion of the blank that is not scored or ablated (the sample may be printed or otherwise coated if it is in finished form).
  • the terms “front”, “back”, “upper”, “lower”, “top”, “bottom” and “side”, refer to the relative positions of portions of containers according to the invention and components thereof when the container is in an upright position with the access opening at the top of the container.
  • the container is a hinged lid container
  • Figure 1 is a side view of a container for consumer goods, according to a first embodiment of the present invention, shown in an open configuration;
  • Figure 2 is a side view of a container for consumer goods, according to a first embodiment of the present invention, shown in a closed configuration;
  • Figure 3 is an overhead view of an unfolded laminar blank for forming a similar container to that shown in Figures 1 and 2.
  • FIGs 1 shows a perspective view of a container 100 according to a first embodiment of the present invention.
  • the container 100 contains a wrapped bundle of consumer goods 60, such as a bundle of cigarettes.
  • the container is formed from a folded laminar blank and has a lid portion 40 and a box portion 20.
  • the lid portion has a first lid side wall 44a, a second lid side wall 44b, and a lid top wall 46.
  • the lid portion also has a lid front wall 42 and a lid back wall (not shown in Figure 1 ).
  • the box portion 20 has a box front wall 22, and a first box side wall 24a.
  • the box portion 20 also has a box bottom wall, a box back wall and a second box side wall (not shown in Figure 1 ).
  • the lid 40 depends along a hinge line (not shown in Figure 1 ) from a top edge of the box back wall, and is movable about the hinge line between an open position (as shown in Figure 1 ) and a closed position.
  • An inner frame 50 is attached to the inside of the box 20 and includes a first inner frame side wall (54a), a second inner frame side wall (not shown in Figure 1 ), and an inner frame front wall 52.
  • the first box side wall 24a is connected to the box front wall by a first box edge portion 25.
  • the first lid side wall 44a is connected to the lid front wall 42 by a first lid edge portion 45.
  • the first box edge portion 25 has a triangular shape, with one side of the triangular shape forming the upper edge 27 of the first box edge portion 25.
  • the first lid edge portion 45 is defined by a single line of weakness extending in the longitudinal direction of the container between the first lid side wall 44a and the lid front wall 42. This effectively, results in the lower edge 47 of the of the first lid edge portion 45 forming a single point in the container, that defines a right-angle turning point between the first lid side wall 44a and the lid front wall 42.
  • Figure 2 shows the container of Figure 1 with the lid 40 now moved to the closed position.
  • at least a portion of the lower edge of the first lid side wall 44a abuts at least a portion of the upper edge of the first box side wall 24a
  • at least a portion of the lower edge of the lid front wall 42 abuts at least a portion of the upper edge of the box front wall 22.
  • the shape of the first lid edge portion 45 and the shape of the first box edge portion 25 are such that, in the closed position of Figure 2, the lower edge 47 of the first lid edge portion 45 is disposed beyond the upper edge 27 of the first box edge portion 45 in a transverse direction of the container.
  • an overhang is created between the lid 40 and the box 20 about the first lid edge portion 45 and the first box edge portion 25.
  • a consumer can therefore place their finger on the triangular surface of the first box edge portion 25 and under the overhanging portion of the lid 40 that is defined by the first lid edge portion 45 and simply push directly upwards on the lid 40, to thereby pivot it about the hinge line into an open position, such as that shown in Figure 1.
  • the box bottom wall and the lid top wall 46 have substantially the same width and length as one another, and this corresponds to the maximum width and length of the container 100. Consequently, the introduction of a gap or overhang at the first lid edge portion 45 and the first box edge portion 25 does not affect the maximum width or length of the container 100.
  • Figure 3 shows a laminar blank 101 for forming a container similar to that shown in Figures 1 and 2.
  • Solid line represent cut lines, and dashed lines of weakness that have been formed by ablated lines on the inner surface of the blank 101 , along which the laminar blank 101 is folded or deformed to form the container 100.
  • the laminar blank 101 comprises a box bottom panel 152, a box front panel 154 depending along an ablated line 156 from the box bottom panel 152, and a box rear panel 158 depending along an ablated line 160 from the box bottom panel 152.
  • Inner box side panels 162 depend along ablated lines 164 from the box rear panel 158 and outer box side panels 166a, 166b depend along ablated lines 168b from the box front panel 154 respectively.
  • Two box dust flaps 170 depend along ablated lines 172 from the first box side panels 162.
