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 consumer goods, such as smoking articles.
  • Smoking articles such as cigarettes and cigars are typically packaged in rigid hinge-lid containers. These typically have a box part having a box front wall, a box rear wall, box side walls and a box base. They also usually have a lid part with a lid front wall, a lid rear wall, lid side walls and a lid top side. The lid part is typically hinged to the box part along a hinge line extending across a back wall of the container. A bundle of smoking articles housed in the box part is commonly wrapped in an inner liner of metallised paper, such as aluminium foil, or other flexible sheet material. To access the bundle of smoking articles within the inner liner, a consumer should remove an upper portion of the inner liner upon first opening of the hinge- lid container.
  • the lid In hinge-lid containers, the lid often further comprises a lid front flap extending from the lower edge of the lid front wall along a fold line.
  • the lid front flap When the container is assembled from the blank, the lid front flap is folded inwards and typically secured to the inner surface of the lid front wall. This advantageously increases the stiffness of the lid.
  • a container for consumer articles comprising a box portion and a hinge lid connected to the box portion along a hinge line and pivotable about the hinge line between a closed position and an open position.
  • a front wall of the container comprises at least one cut out portion, such that, when the hinge lid is in the closed position, a front wall of the lid overlies the cut out portion in the container front wall.
  • the hinge lid comprises a lid flap depending from the lid front wall along an edge fold line, the lid flap being folded inwards and attached to the inner surface of the lid front wall by an adhesive provided on a portion of the inner surface of the lid flap.
  • the lid flap comprises at least a cut line forming an adhesive-free retention tab depending from the lid front wall along the edge fold line and at least partly raised above the plane of the remainder of the lid flap.
  • a blank for forming a container for consumer articles comprising a box-defining blank portion for forming a box portion of the container and a lid-defining blank portion for forming a lid of the container.
  • the box-defining portion comprises a box front panel for forming at least part of a front wall of the container.
  • the box front panel comprises at least one cut portion formed therein.
  • the lid-defining blank portion comprises a lid front panel for forming a lid front wall and at least one lid flap depending from the lid front panel along an edge fold line. In the assembled container, when the hinge lid is in the closed position, the lid front wall overlies the at least one cut portion.
  • the lid flap comprises a cut line forming a tab depending from the lid front panel along the edge fold line, such that when, during assembly of the container, the lid flap is folded towards and attached to the inner surface of the lid front wall and the tab is at least partly raised above the plane of the remainder of the lid flap.
  • hinge lid containers for consumer goods wherein a front wall of the container comprises at least one cut out portion, such that, when the hinge lid is in the closed position, a front wall of the lid overlies the cut out portion.
  • the hinge lid comprises a lid flap depending from the lid front wall along an edge fold line. The lid flap is folded inwards and attached to the inner surface of the lid front wall by an adhesive provided on a portion of the inner surface of the lid flap.
  • the hinge lid comprises at least a cut line forming an adhesive-free retention tab depending from the lid front wall along the edge fold line and at least partly raised above the plane of the remainder of the lid flap.
  • the cooperation between the retention tab and the cut out portion generates an audible sound.
  • the retention tab cooperates with the cut out portion in the front wall of the container, the lid may be held securely in the closed position.
  • the production of a sound during movement of the hinge lid of containers according to invention from the open position to the closed position advantageously provides the consumer with an audible indication of closure of the container.
  • This may advantageously be employed, for example, to ensure that the container has been fully closed, thereby ensuring that all parts of the consumer goods are retained within the container.
  • the retention tab is also folded along the same edge fold line.
  • the portion of inner surface of the lid flap forming the retention tab is free from adhesive, the inherent spring-back force of the blank is enough for at least a portion of the retention tab to naturally project away from the remainder of the lid flap and thus be raised above the plane of the remainder of the lid flap.
  • the retention tab is separated from the remainder of the lid flap prior to the first opening of the container and thus projects away from the remainder of the lid flap substantially in its entirety.
  • the retention tab is connected to the remainder of the lid flap by one or more ties and becomes separated from the remainder of the lid flap when the hinge lid is brought from the closed position to the open position for the first time.
  • 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 lid of the outer housing in the closed position and the hinge line at the back of the container.
  • the back wall of the container is the wall comprising the hinge line.
  • inner surface is used throughout the specification to refer to the surface of a component of the assembled container that is facing towards the interior of the container, for example towards the consumer goods, when the container is in the closed position.
  • outer surface is used throughout the specification to refer to the surface of a component of the container that is facing towards the exterior of the container. It should be noted that referring to a surface as the inner surface or the outer surface is not necessarily equivalent to referring to a certain side of a blank used in assembly of the container. Depending on how the blank is folded around the consumer goods, areas that are on the same side of the container can either face towards the inside or the towards the outside of the container.
  • hinge line refers in particular to a line about which the lid may be pivoted in order to open the container.
  • a hinge line may be, for example, a pre-folded fold line or a score line in the panel forming the back wall of the container.
  • the term “height” refers to the maximum distance between the upper edge and the lower edge of a cut out portion as measured with respect to a vertical axis of the front wall of the container.
  • the term “width” refers to the maximum distance between the left edge and the right edge of a cut out portion as measured with respect to a horizontal axis of the front wall of the container.
  • the term “height” shall be construed as referring to the distance between the uppermost point and the lowermost point of the perimeter of the cut out portion.
  • the term “width” shall be construed as referring to the distance between the points of the perimeter of the cut out portion farthest from each other with reference to a horizontal axis of the front wall of the container.
  • the term "spring-back force" is a known term of art for referring to an inherent property of a laminar blank. It is sometimes also referred to as 'the crease recovery' and relates to the residual stresses that, after a bending operation, cause a sheet to spring back slightly.
  • the "spring-back force” is what causes the tendency of the lid flap to move back, to an extent, towards the unbent position.
  • the hinge lid comprises a lid flap depending from the lid front wall along an edge fold line. The lid flap is folded inwards and attached to the inner surface of the lid front wall by an adhesive provided on a portion of the inner surface of the lid flap.
  • the lid flap comprises at least a cut line forming an adhesive-free retention tab depending from the lid front wall along the edge fold line and at least partly raised above the plane of the lid flap.
  • the retention tab is configured to cooperate with a cut out portion provided in a front wall of the container, such that, during pivotal movement of the hinge lid from the open position to the closed position, the retention tab slides along the container front wall and into the cut out portion in the container front wall.
  • the cut line is typically U-shaped.
  • U-shaped is used to mean that the cut line typically comprises a segment extending substantially parallel to the edge fold line and two legs extending from the end of said segment to the edge fold line.
  • the ends of the U-shaped cut line are connected by the edge fold line.
  • other shapes of the cut line may be possible, provided that the cut line and the fold line together define the perimeter of the retention tab.
  • the cut line is provided at a location in the lid flap such that, when the container is closed, the retention tab is in alignment with the cut out portion in the front wall of the container.
  • the cut line is provided at a central location in the lid flap with respect to a transverse axis of the lid flap.
  • the cut out portion is preferably provided in a central location in the front wall of the container with respect to a transverse axis thereof.
  • the cut line is a continuous cut line. Accordingly, the retention tab is separated from the remainder of the lid flap along the whole of the cut line and, due to the spring-back properties of the blank, naturally projects away from the remainder of the lid flap.
  • the cut line is provided as a line having slits or cuts arranged at predetermined intervals and separated by one or more ties, such that for separating the retention tab from the remainder of the flap a finite, relatively small number (1 -10) of ties needs to be broken.
  • the cut line may be provided as two L-shaped slits or cuts separated by a single tie.
  • the cut line may, for example, be provided as three cuts or slits that together define three sides of the perimeter of the retention tab, where consecutive cuts or slits are separated by ties. Thus, two ties need to be broken to separate the lid flap from the remainder of the lid flap.
  • the retention tab tends to move back in the unbent position, but is held by the ties in a configuration where it is partially raised above the plane defined by the remainder of the lid flap.
  • a portion of the retention tab is raised by about 1 -2 mm above the plane of the remainder of the lid flap.
  • the retention tab is separable from the remainder of the lid flap upon first opening the container.
  • interaction of the partially raised retention tab with the cut out portion in the front wall of the container causes the rupture of the ties connecting the retention tab with the remainder of the tab, and the retention tab becomes free to project away from the lid flap due to the spring-back force.
  • retention tab is held very close to the plane of the remainder of the lid flap during assembly of the container, and so the likelihood that the retention tab may be damaged through interaction with the packing apparatus, or that the retention tab may hinder the packing operation is significantly reduced.
  • separation of the retention tab from the remainder of the lid flap is easily achieved upon opening the container for the first time.
  • the retention tab engages with an edge of the cut out portion to lock the hinge lid in the closed position.
  • it is necessary to apply a force to release the retention tab from engagement with the edge of the cut out portion. Accordingly, the likelihood of the hinge lid being inadvertently moved to an open position is significantly reduced. This advantageously prevents the consumer goods or parts of the consumer goods from falling out of the container.
  • the retention tab is preferably released from engagement with the edge of the cut out portion. This may result in the generation of another sound.
  • the at least one cut out portion is formed in a front wall of the box portion. Because the lid, including the lid flap and the retention tab, and the box, including the cut out portion, may be formed from a single blank, it is advantageously very easy to ensure that the retention tab and the cut out portion are in substantial alignment when the container is formed from the blank.
  • the front wall of the box portion comprises a first panel and a front tab extending from the upper end of the first panel, and the cut out portion is formed in the front tab.
  • the container comprises an inner frame mounted within the box portion.
  • the inner frame comprises a frame front wall, a portion of which extends beyond an upper edge of a front wall of the box portion.
  • the at least one cut out portion is formed in the frame front wall. This is advantageous because, in the closed position, the lid front wall can easily align with the box front wall.
  • the container presents to the user a substantially flat front surface.
  • the at least one cut out portion has a height (H) and a width (W).
  • the height (H) is preferably at least about 0.3 mm, more preferably at least about 0.5 mm. In addition, or as an alternative, the height (H) is preferably less than about 5 mm, more preferably less than about 3 mm.
  • the width (W) of the cut out portion is at least about 5 percent of the overall width of the front wall of the container. More preferably, the width (W) of the cut out portion is at least about 10 percent of the overall width of the front wall of the container. In addition, or as an alternative, the width (W) of the cut out portion is less than about 95 percent of the overall width of the front wall of the container. More preferably, the width (W) of the cut out portion is less than about 80 percent of the overall width of the front wall of the container.
  • the retention tab extends from the edge fold line by at least about 0.5 mm. More preferably, the retention tab extends from the edge fold line by at least about 1 mm.
  • the retention tab preferably extends from the edge fold line by less than about 15 mm. More preferably, the retention tab extends from the edge fold line by less than about 10 mm. It has been found that a retention tab of such size produces a particularly clear sound when interacting with the cut out portion. On the other hand, retention tabs extending from the edge fold line by less than 0.5 mm may fail to produce a sufficiently audible sound. Further, retention tabs extending from the edge fold line by more than 10 mm have been found to not always interact correctly with the cut out portion.
  • Containers according to the present invention find application as containers for consumer goods, in particular elongate consumer goods such as smoking articles. However, they can also be used for several other types of consumer goods.
  • Containers according to the present invention are at least partially formed from a blank having a predetermined thickness.

Alternatively, other consumer goods may be housed inside the container.
  • containers according to the invention may be designed to hold different total numbers of smoking articles, or different arrangements of smoking articles.
  • containers according to the invention may be designed to hold a total of between ten and thirty smoking articles.
  • the smoking articles may be arranged in different collations, depending on the total number of smoking articles.
  • Containers according to the present invention may hold smoking articles of the same type or brand, or of different types or brands.
  • both filter-less smoking articles and smoking articles with various filter tips may be contained, as well as smoking articles of differing length (for example, between about 40 mm and about 180 mm), diameter (for example, between about 4 mm and about 9 mm).
  • the dimensions of the container are adapted to the length of the smoking articles, and the collation of the smoking articles.
  • the outer dimensions of the container are between about 0.5 mm to about 5 mm larger than the dimensions of the bundle or bundles of smoking articles housed inside the container.

  • Two side wall panels 316 extend from the front wall panel 314, two side wall panels 317 extend from the rear wall panel 318, and lid dust flaps 319 extend from the side wall panels 317.
  • the front wall panel 314 forms the container front wall
  • the rear wall panel 318 forms the container rear wall
  • the side wall panels 316, 317 overlap to form right and left container side walls
  • the lid dust flaps 319 overlap top wall panel 320 to form the lid top wall.
  • the side wall panels 316, 317 are substantially the same size and shape as each other.
  • the panels 316, 317 directly overlie each other with their free edges substantially aligned, such that the inner side wall panel is barely visible.
  • the lid dust flaps 319 are smaller than the top wall panel 320. When the container is formed, the lid dust flaps 319 lie inside the top wall panel 320. They provide additional structural support for the container (lid) top wall, but are not visible from the outside of the container.
  • the lid blank portion 3002 comprises a lid flap panel 325 depending from the front wall panel 314 along an edge fold line 326.
  • the lid flap panel 325 comprises a U-shaped cut line 327 that defines, with the edge fold line 326, a retention tab.
  • the cut line 327 is not continuous, but it is provided as a line of slits separated by ties connecting the retention tab to the remainder of the lid flap panel 325.
  • the additional blank 400 comprises a front frame panel 401 for forming a frame front wall and two side frame panels 402 extending from the front frame panel 401 for forming side frame walls.
  • the front frame panel 401 comprises a cut out portion 404 arranged such that, when the inner frame is mounted within the box portion of the container and the hinge lid is in the closed position, the retention tab form defined by the cut line 327 is in alignment with the cut out portion 404.
  • the lid flap panel 325 is folded inwards and attached by a layer of adhesive to the inner surface of the lid front wall panel. Because it is free from adhesive, the retention tab formed by the cut line tends to spring back from the remainder of the lid flap.
  • the retention tab is only partly raised to form a non null angle with the remainder of the lid flap.
  • a raised portion of the retention tab is available for engagement with an edge of the cut out portion in the inner frame and, because of this interaction, the retention tab is separated from the remainder of the lid flap as the tie or ties of the cut line 327 are broken.
  • FIG. 3 shows a blank 500 for forming an alternative embodiment of a container according to the present invention.
  • the lid blank portion 5002 comprises a lid flap panel 525 depending from the front wall panel 514 along an edge fold line 526.
  • the lid flap panel 525 comprises a U-shaped cut line 527 that defines, with the edge fold line 326, a retention tab.
  • the cut line 527 is not continuous, but it is provided as a line of slits separated by ties connecting the retention tab to the remainder of the lid flap panel 525.
  • the blank 500 differs from the blank 300 described above in that a cut out portion is formed in a front wall panel 508 of the box blank portion 5001 for forming a box portion of the container.
  • This is advantageous in that, because the hinge lid blank portion 5002 and the box blank portion 5001 form part of the same blank, it is easier to control the relative arrangement of the cut out portion in the front wall panel 508 and the cut line 527 in the lid flap panel 525.
  • the retention tab and the cut out portion will be correctly aligned for proper cooperation and generation of a sound when the container is closed and opened.
