Description

TECHNICAL FIELD

The present invention relates to a tobacco industry product pack containing a wrapped bundle of tobacco industry products such as smoking articles and, in particular, cigarettes. The invention also relates to a container to receive a wrapped bundle of tobacco industry products, and to a blank for a hinged-lid container.

BACKGROUND

Tobacco industry product packs containing a wrapped bundle of tobacco industry products are known. The wrapped bundle includes a group or charge of smoking articles enclosed by a flexible barrier material. The barrier material may be sealed to maintain the freshness of the smoking articles and access may be obtained by pulling on a label adhered to the barrier material so that a weakened portion of the barrier material beneath the label is lifted to form an extraction opening through which smoking articles may be removed. The label may include a region of pressure sensitive adhesive to enable it to be re-positioned over the extraction opening once a smoking article has been removed to maintain the freshness of the remaining smoking articles within the wrapped bundle. In some instances, during manufacture the barrier material may be sealed to an extent sufficient to maintain a partial vacuum within the wrapped bundle which is released when the label is pulled for the first time and air is allowed into the bundle through the extraction opening.
Sealing of the barrier material around the group of smoking articles during manufacture may be achieved by folding the barrier material around the group and fin-sealing where the edges of the barrier material meet, thereby forming sealed seams that extend along each side surface of the bundle. The seams can be folded against the side surface from which they protrude when the wrapped bundle is inserted into a container to provide a tobacco industry product pack.

DETAILED DESCRIPTION

With reference to FIGS. 1 to 3, there is shown a wrapped bundle 1 of smoking articles. The wrapped bundle 1 comprises a group or charge of smoking articles which has been wrapped in a layer of flexible barrier material 2 which is folded about the charge and has a front surface 3 and a rear surface 4 which are spaced from each other by parallel side surfaces 5. The barrier material 2 also has an upper end surface 6 that extends across the top of the charge. The front surface 3 meets the upper end surface 6 at an upper front edge fold 7. The rear surface 4 meets the upper end surface 6 at an upper rear edge fold 8 and, each side surface 5 meets the upper end surface 6 at an upper short edge fold 9. Furthermore, each side surface 5 meets the front surface 3 at a long front edge fold 10 and meets the rear surface 4 at a long rear edge fold 11.
The barrier material 2 is wrapped around the charge and fin-sealed to form seams 13 that extend along the length of each of the side surfaces 5 of the wrapped bundle 1. Fin-sealing is a commonly used horizontal wrapping process in which a product is overwrapped in a flexible sheet material, such as film or foil and which creates a “fin” along edges of the wrapped product. The “fin” may be folded down, using heat and pressure, so that it lies substantially flat. The process of fin-sealing is often referred to as “flow wrapping”.
The wrapped bundle 1 according to embodiments of the present invention has the seam 13 extending along each of its side surfaces 5. However, as the side surfaces 5 are identical in every way, reference is made to only one side surface 5 and its respective seam 13 in the description that follows.
FIG. 1 shows the wrapped bundle 1 after the fin-sealing process has been completed but prior to any folding of the resultant seam 13. As can be seen in FIG. 1, the seam 13 effectively protrudes from the wrapped bundle 1 generally at right-angles to its side surface 5. The seam 13 also extends beyond the upper end surface 6 to an apex 14 of a triangular-shaped flap 15 which is formed as a result of the wrapping, folding and sealing of the barrier material 2 around the charge of smoking articles. As the seam 13 also extends beyond a lower end surface (not shown) opposite to the upper end surface 6 of the wrapped bundle 1 in exactly the same way, and the seam 13 is folded in exactly the same way at both ends, the description below refers only to the folding of the seam 13 at the upper end of the wrapped bundle 1.
With reference to FIG. 2, the wrapped bundle 1 is shown after the seam 13 extending from the side surface 5 has been folded down so that it lies against the side surface 5 of the wrapped bundle 1.
Next, with reference to FIG. 3, the triangular-shaped flap 15 extending from the upper side edge fold 9 of the wrapped bundle 1 is folded down so that it overlies the side surface 5 of the wrapped bundle 1. As a result of the folding of the triangular-shaped flap 15, part of the seam 13 is doubled over adjacent to the upper end surface 6. It will be appreciated that only a triangular-shaped portion 16 of the doubled over part of the seam 13 is visible in FIG. 3, the remainder being hidden behind the folded flap 15.
The wrapped bundle 1, with the seam 13 and flap 15, which has been folded as described above, is inserted into a container 17, as shown in FIG. 4, to form a tobacco industry pack. The container 17 comprises a base 18 having a front panel 19 and a rear panel 20 spaced from each other by parallel side panels 21, and a lid 22 hingedly attached to the rear panel 20. A portion of the wrapped bundle 1 protrudes from an open end of the base 18 and is received in the lid 22 when the lid 22 is closed. A container 17 of this type is well-known in the tobacco industry and is commonly referred to as a “hinged-lid” container.
Although the side panel 21 of the base 18 retains the seam 13 of the wrapped bundle 1 against the side surface 5 against which it has been folded prior to insertion into the base 18, the portion of the seam 13, together with the flap 15 and the triangular-shaped portion 16 of the doubled-over part of the seam 13, which remains exposed due to the wrapped bundle 1 extending from the base 18, are not constrained by the base 13. As a result, this part of the seam 13, the flap 15 and the triangular-shaped portion 16 tend to protrude slightly from the wrapped bundle 1 after the lid 22 has been opened. This can result in the lid 22 snagging against the flap 15, or the triangular-shaped portion 16, as it is pivoted into its closed position, thereby preventing or hindering closure of the lid 22.
Embodiments of the present invention provide a tobacco industry pack which addresses this issue and overcomes or substantially prevents snagging of the lid 22 against the wrapped bundle 1 as the lid 22 is closed.
Embodiments of the present invention provide a seam retainer 23 that holds the seam 13 down against the side surface 5 of the wrapped bundle 1, together with the flap 15 and/or the triangular-shaped portion 16, so that the lid 22 does not come into contact with them, or so that the the lid 22 slides over them without being hindered or restricted.
As will become apparent from the description that follows, the seam retainers 23 are configured so that snagging of the lid 22 against the seam retainers 23 is also reduced or prevented. It will be appreciated that a seam retainer 23 extends from both sides of the base 18, although only one seam retainer 23 is referred to in the description that follows.
With reference to the embodiment of FIG. 4, the seam retainer 23 is attached to and extends from the base 18 and forms an extension of the side panel 21 of the base 18. The seam retainer 23 extends partially, but not entirely, over the portion of the side surface 5 of the wrapped bundle 1 that extends from the base 18 and over the seam 13. The seam retainer 23 also extends partially over the flap 15 and the triangular-shaped portion of the seam 16. The seam retainer 23 is formed from a material which is rigid enough to retain or press or hold the seam 13, the flap 15 and the triangular-shaped portion 16, against the side surface 5 to prevent the flap 15 and/or the seam 13 from protruding from the side surface 5 and interfering with closure of the lid 22.
With reference to FIG. 4, it can be seen that the seam retainer 23 extends across the full width of the side surface 5 between the long front and long rear edge folds 10, 11. However, an upper edge 24 of the seam retainer 23 extends upwardly, at an angle away from the long front edge fold 10 from a point on the long front edge fold 10 remote from where the long front edge fold 10 meets the upper short edge fold 9, towards the long rear edge fold 11 and the upper short edge fold 9. As shown in FIG. 4, the upper edge 24 of the seam retainer 23 extends over part of the flap 15 and is rounded off at a region 24 a closest to the upper short edge fold 9. This region is closer to the long rear edge fold 11 than to the long front edge fold 10. The upper edge 24 then meets the long rear edge fold 11 at a point on the long rear edge fold 11 that is spaced from the point at which the long rear edge fold 11 meets the the upper short edge fold 9. The point at which the upper edge 24 meets the long rear edge fold 11 may be closer to the upper short edge fold 9 than at the point at which the upper edge 24 meets the long front edge fold 10.
Although the rounded region 24 a of the upper edge 24 of the seam retainer 23 remains spaced from the upper short edge fold 9, as shown in FIG. 4, in an alternate embodiment, the seam retainer 23 may at least extend to the upper short edge fold 9 for part of the length of the upper short edge fold 9.
From FIG. 4, it can be seen that the seam retainer 23 extends over part of the flap 15 and the majority of the triangular shaped portion 16 of the seam 13, but that the side surface 5 remains partially exposed in a region adjacent to the upper short edge fold 9. Therefore, the flap 15, and the seam 13, including its triangular shaped portion 16, is held down against the side surface 5 of the wrapped bundle 1 to prevent interference with the lid. Furthermore, because the seam retainer 23 is shaped as described above so that it does not extend over the entire side surface 5 and is, in particular, remote from the upper short edge fold 9, at least adjacent to where the upper short edge fold 9 meets the long front edge fold 10, interference between the seam retainer 23 and the lid 22 is also prevented or reduced, enabling the lid 22 to be closed without hindrance.
A second embodiment of the invention is shown in FIG. 5. This embodiment is similar to the embodiment shown in FIG. 4, except that the flap 15 remains free and exposed, i.e. the seam retainer 23 extends only over the triangular-shaped portion 16 of the seam 13 that extends from beneath the flap 15, but not over the flap 15 itself. Effectively, the upper end of the seam retainers 23 are chamfered so they extend at an angle relative to the upper short edge fold 9, thereby revealing part of the side surface 5 bounded by the upper short edge fold 9 and, the long front edge fold 10.
As shown in FIG. 5, in this embodiment the upper edge 24 of the seam 23 is straight and extends upwardly at an angle from a point on the long front edge fold 10, spaced from where the long front edge fold 10 meets the upper short edge fold 9, towards the point at which the long rear edge fold 11 meets the upper short edge fold 9 and the upper rear edge fold 8. The seam retainer 23 extends at an angle so that it is aligned adjacent, and parallel to, an edge 15 a of the flap 15.
It will be appreciated that, in the illustrated embodiment of FIG. 5, the seam retainer 23 covers the majority of the triangular-shaped portion 16 of the seam 13. However, it will be understood that the seam retainer 23 may also extend over the whole of the triangular-shaped portion 16 of the seam 13.
By arranging the seam retainer 23 so that it covers only the triangular-shaped portion 16 of the seam 13, without extending over the flap 15, the seam retainer 23 and triangular-shaped portion 16 remain flatter and are positioned closer to the side surface 5. This is acceptable, as it has been found that it is the triangular-shaped portion 16, rather than the flap 15, that is predominantly responsible for intefering with the lid 22 during closure. Therefore, retention of only the triangular-shaped portion 16 with the seam retainer 23 has been found to be a good solution and also reduces the tendency for the lid 22 to contact the seam retainer 23 during closure of the lid 22.
In either of the embodiments described above, the seam retainer 23 that extends across one side surface 5 of the wrapped bundle 1 may be attached to the seam retainer 23 that extends across the opposite side surface 5 by a connecting panel 25 which is preferably integrally formed with the seam retainers 13, as shown in FIG. 6. In particular, the seam retainers 13 may be folded relative to the connecting panel 25 so that the seam retainers 13 and connecting panel 25 together form a U-shaped structure, as shown in FIG. 7.
The seam retainers 23 are shaped so that the connecting panel 25 can be positioned against, and attached to, the inside of the front panel 19 of the base 18, i.e. between the front surface 3 of the wrapped bundle 1 and the front panel 19. The connecting panel 25 may be entirely concealed behind the front panel 19, so that it is not visible when the lid 22 is opened. Alternatively, the connecting panel 25 may protrude from the base 18 so as to extend over part of the front surface 4 of the wrapped bundle 1. The part of the connecting panel 25 that protrudes from the base 18 will then be visible when the lid 22 is opened.
The seam retainers 23 have free edges 28 remote from the connecting panel 25. The free edges 28 may be aligned with the long rear edge fold 11. However, in another embodiment, shown in FIG. 8, the free edges 28 of the seam retainers 23 are extended by tabs 29. The tabs 29 are folded so that they extend around the long rear edge fold 11 of the wrapped bundle 1 so that they extend towards each other and each overlie a part of the rear surface 4 of the wrapped bundle 1. The tabs 29 prevent the lid 22 from sliding between the side surface 5 and the seam retainer 23. The tabs 29 also provide additional rigidity to the seam retainer 23. If required, the tabs 29 may be attached to the rear surface 4 of the wrapped bundle 1.
When the connecting panel 25 is attached to the front panel 19 of the base 18, the fin seal 13 and flap 15 may still urge the seam retainers 23 outwardly, thereby causing the lid 22 to foul on them when it is pivoted into a closed position. Therefore, in a preferred embodiment, the connecting panel 25 is attached to the rear panel 20 of the base 18 of the container 17 so that it lies between the rear panel 20 of the base 17 and the rear surface 4 of the wrapped bundle 1, as illustrated in FIGS. 9 and 10. A connecting panel 25 which is attached to the rear panel 20 is the preferred embodiment when the seam retainers 23 extend over the triangular-shaped portion 16 of the seam 13, without extending over the flaps 15, as previously described above.
In FIG. 9, the seam retainers 23 extend beyond the connecting panel 25, so that the connecting panel 25 is entirely located behind the rear panel 20. However, in the embodiment shown in FIG. 10, the connecting panel 25 extends to the upper end of the seam retainers 23 and so do extend into the lid 22 from the base 17. An upper edge 25 a of the connecting panel 25 therefore lies adjacent to, and in alignment with, the upper rear edge fold 8 of the wrapped bundle 1. FIG. 11 shows the seam retainers 23 and connecting panel 25 of FIG. 10 after it has been inserted into a container 18 so that it protrudes from the base 17, and from which it can be seen that the upper edge 25 a of the connecting member 25 extends from the base 17 to the same extent as the seam retainers 23.
FIG. 12 shows the same view as FIG. 11, after a wrapped bundle 1 has been inserted into the container 18. The embodiments of FIGS. 10 to 12 may provide additional strength or rigidity to the seam retainers 23, may help to maintain the seam retainers 23 against their respective side surfaces 5 and, may prevent the possibility that the side walls 22 a of the lid 22 may slide down between the seam retainers 23 and the side surfaces 5 of the wrapped bundle 1 upon closure of the lid 22. It will be appreciated, that, if the wrapped bundle 1 is provided with a cover flap that extends over a region of the barrier material that is separated from the remainder of the barrier material to form an extraction opening, the upper edge 25 a of the connecting panel 25 may act as a ‘stop’ to prevent the cover flap from being pulled back beyond the upper surface of the wrapped bundle 1.
As the seam retainers 23 are tied together across the rear of the wrapped bundle 1 by the connecting panel 25, they are prevented from moving apart at the rear of the bundle 1, which is where the side walls 22 a of the lid 22 first begin to overlap the seam retainers 23 as the lid 22 is closed.
In another embodiment, an insert protrudes from the base in a direction towards the lid. The insert may comprise a side flaps facing each side panel and, a connecting panel extending between each side flap and so is similar to the seam retainers 23 and connecting panel 25 described above, except that the side flaps may extend over the whole or part of the side surface of the wrapped bundle 1. The connecting panel 25 extends across and is placed against the rear panel 4 of the container 1 and is preferably attached to the rear panel 4. The side flaps may extend from the base 17 in a direction towards the lid 22. Similarly, the connecting wall 25 may extend from the base 17 to the same or lesser extent as the side flaps.
Another embodiment is described with reference to FIGS. 13 and 14, and in which the seam retainers 23 are integrally formed with the the base 18. As can be seen from the unfolded container blank of FIG. 13, the inner side panels 21 extending from the rear panel 4 comprise extension panels 30 that are integrally formed with the inner side panels 21 and separated therefrom by a fold line 31. When the blank is assembled, the extension panels 30 are folded inwardly so that they overlie the the side panel 21 from which they extend, as shown in FIG. 14. As most clearly apparent from FIG. 14, the extension panels 30 each have a portion 33 that extends beyond an upper edge 32 of the side panel 21 and it is this portion 33 that covers the triangular-shaped portion 16 of the seam 13 and retains the triangular-shaped portion 16 of the seam 13 against the side surface 5 of the wrapped bundle 1. The outer side panels 21 a, which extend from the front panel 3 overlie the inner side panels 21 and are aligned with the side panels 22 a of the lid 22.
Each extension panel 30 may be attached to its corresponding side panel 21 using adhesive. In a preferred embodiment, the portion 33 of the extension panel 30 that protrudes beyond the side panel 21 is shaped so as to cover the whole of the triangular-shaped portion 16.
The barrier material 2 may comprise a single layer. Alternatively, the barrier material 2 may comprise a laminate material of two or more layers, for example three layers. Each layer of the barrier material may comprise a polymer (for example polypropylene), a metal foil, a metallised foil or other flexible material suitable for packaging.
