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.
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.
In accordance with embodiments of the invention, there is provided a tobacco industry product pack comprising a container including a base having a front panel and a rear panel spaced from each other by side panels, and a lid hingedly attached to the rear panel; a wrapped bundle of tobacco industry products having a portion extending from the base which is received in the lid when the lid is closed, said wrapped bundle comprising a barrier material having a front surface facing the front panel, a rear surface facing the rear panel, a side surface facing each side panel, and an upper end panel that meets the front, rear and side surfaces at upper front edge, upper rear edge and upper short edge folds respectively, the barrier material being fin-sealed to form a seam along each side surface, and a seam retainer attached to the base that partially extends over each of the side surfaces of said portion of the wrapped bundle extending from the base to retain each seam against its side surface.
Preferably, the front surface meets each side surface at a long front edge fold and the rear surface meets each side surface at a long rear edge fold. Each seam retainer may comprise an upper edge that extends across the side surface from said long front edge fold, at a position spaced from the upper short edge fold, towards the upper short edge fold and the long rear edge fold.
The upper edge of each seam retainer may be spaced from the upper short edge fold.
Each seam retainer may be shaped to extend closer to the upper short edge fold nearer to the long rear edge fold than to the long front edge fold.
The upper edge of the seam retainer may meet the long rear edge fold at a position spaced from the upper short edge fold.
In some embodiments, the upper edge of each seam retainer extends linearly across the side surface from said long front edge fold to where the upper short edge fold, the long rear edge fold and the upper rear edge folds meet.
Preferably, the barrier material comprises a triangular-shaped flap extending from each upper short edge fold of the wrapped bundle and the seam formed along each side surface of the wrapped bundle extends to an apex of each flap, each seam and flap being folded about the upper short edge fold against the side surface so that a triangular-shaped section of the seam extends from beneath the folded flap.
Each seam retainer may extend over the triangular-shaped section of the seam extending from beneath the flap folded against each side surface, but without extending over the folded flap.
Preferably each seam retainer extends over the whole of the triangular-shaped section of the seam extending from beneath the flap on each side surface.
The seam retainers may be joined together by a connecting panel. The connecting panel may lies between the rear surface of the wrapped bundle and the rear panel of the base.
In one embodiment, the connecting panel extends to the upper rear edge fold of the wrapped bundle. Alternatively, the connecting panel may be spaced from the upper rear edge fold of the wrapped bundle.
The seam retainers may extend beyond the connecting panel towards the upper rear edge fold.
In some embodiments, the connecting panel extends between the front surface of the wrapped bundle and the front panel of the base. The connecting panel may be wholly received between the front surface of the wrapped bundle and the front panel of the base.
Each seam retainer may have a tab that extends beyond each side surface of the wrapped bundle, said tabs extending towards each other between the rear surface of the wrapped bundle and the rear panel of the base.
The seam retainers may be integrally formed with the connecting panel and maybe folded relative to the connecting panel.
Preferably, the connecting panel is attached to the base.
In another embodiment, the seam retainers may be an integral part of the container. In particular, the seam retainers may comprise extension panels depending from each side panel of the base.
Each extension panel may be folded relative to the side panel from which it depends. Each extension panel may be located between said side panel of the base and said side surface of the wrapped bundle.
Preferably, each extension panel comprises a portion that extends beyond an upper edge of the side panel about which it is folded, said portion extending towards the upper side edge fold of the wrapped bundle.
According to another aspect of the invention, there is provided a container to receive a wrapped bundle of tobacco industry products, the container comprising a base having a front panel, a rear panel, side panels that space the front and rear panels from each other, and a lid hingedly attached to the rear panel, the side panels having an upper edge facing the lid; wherein a side extension panel depends from each side panel, each side extension panel being folded relative to the side panel from which it depends to overlap said side panel, each side extension panel having a portion that extends beyond said upper edge of the side panel to cover part of a side surface of a wrapped bundle that protrudes from the base when the wrapped bundle is received in the container.
Each side extension panel may be adhered to its side panel in a region of overlap.
According to another aspect of the invention, there is provided a blank for a hinged-lid container comprising a front panel, a rear panel and side panels having an upper edge, the side panels being foldable during assembly to form a base for a container to receive a wrapped bundle of tobacco industry products protruding therefrom, wherein a side extension panel depends from each side panel, each side extension panel being foldable relative to the side panel from which it depends to overlap said side panel, each side extension panel being shaped to extend beyond said edge of the side panel to cover a portion of a side surface of a wrapped bundle protruding from an assembled base.
According to another aspect of the invention, there is provided a container to receive a wrapped bundle of tobacco industry products comprising a base having a front panel and a rear panel spaced from each other by side panels, and a lid hingedly attached to the rear panel; an insert protruding from the base in a direction towards the lid, said insert comprising side flaps facing each side panel and, a connecting wall extending between and connecting each side flap, wherein the connecting wall is placed against the rear panel of the container.
The connecting wall is preferably attached to the rear wall of the container and the side flaps may extend from the base.
Preferably, the connecting wall extends from the base to the same extent as the side flaps.
Embodiments of the invention will now be described, by way example only, with reference to the accompanying drawings, in which:
With reference to
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.
With reference to
Next, with reference to
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
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
With reference to
Although the rounded region 24a of the upper edge 24 of the seam retainer 23 remains spaced from the upper short edge fold 9, as shown in
From
A second embodiment of the invention is shown in
As shown in
It will be appreciated that, in the illustrated embodiment of
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
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
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
In
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 22a 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
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.
