Detailed Description

A tobacco industry product refers to any item made in, or sold by the tobacco industry, typically including a) cigarettes, cigarillos, cigars, tobacco for pipes or for roll-your-own cigarcttcs, (whcthcr bascd on tobacco, tobacco dcrivativcs, cxpandcd tobacco, reconstituted tobacco or tobacco substitutes); b) non-smoking products incorporating tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes such as snuff, snus, hard tobacco, and heat-not-burn products; and c) other nicotine-delivery systems such as inhalers, lozenges and gum. This list is not intended to be exclusive, but merely illustrates a range of products which are made and sold in the tobacco industry The term "smoking article" includes smokeable products such as cigarettes, cigars and cigarillos whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes and also heat-not-burn products. The smoking article may be provided with a filter for the gaseous flow drawn by the smoker.

As used herein, the term "tobacco industry pack" includes any pack that can receive and contain a tobacco industry product.

The tobacco industry pack to which embodiments of the present invention primarily o rolates, and in which is received the folded inner frame according to embodiments of the invention, is primarily intended for holding two side-by-side bundles of cigarettes each of which have a narrower diameter than a standard cigarette. This type of cigarette is often referred to as a slim' cigarette.

An unfolded inner frame blank ito form a folded inner frame 2 (see Figure 2) for insertion into a tobacco industry pack 3 (see Figure 3) is shown in Figure 1. The blank 1 and inner frame 2 has a front panel 4 formed from two front panel sections a, 4b, separated by a central fold line 5 and two secondary fold lines 6, 7, parallel to and spaced from the central fold lines to form a pair of dividing wall panels 8, 9 between the two front panel sections a, 4b. When the blank 1 is folded, as explained below, the central fold line 5 forms an apex. The secondary fold line 6 joins one of the dividing wall panels 8 to front panel section a, whereas the other secondary fold line 7joins the other dividing wall panel 9 to front panel section 4b.

A pair of elongate slots io,ii are formed in each dividing wall panel 8,9 parallel to, and spaced from, the central fold line s, for reasons that will be explained below.

Each front panel section a, 4b has a cut-out region 12 formed in an upper edge 20 of the inner framc blank ito facilitatc thc removal of smoking articics from a pack 3 in 3o which the folded inner frame 2 is located.

An end panel 13,14 extends from an edge of each front panel section a, 4b, each end panel 13,14 being foldable relative to its associated front pand section a, 4b from which it extends about a fold line 15.

The rear wall of the inner frame blank 1 is formed from two rear panel sections 16a, i6b.

One rear panel section i6a extends from an edge of end pane' 13, whilst the other rear panel section i6b extends from an edge of end panel 14. Each rear panel section 16a, i6b is foldable relative to its associated end panel 13, 14 about a fo'd line 17, shown in dashed lines in Figure 1. A cut line 18 is also formed in each rear panel section i6a, i6b that extends from and interupts the fold line 17 to form a central tab 19 out of a part of the rear panel section i6a, i6b, which is enclosed by the cut line iS and extends from an end panel 13, 14.

jo The fold fine 17 does not extend all the way to the tipper and lower edges 20, 21 of the inner frame blank 1. Tnstead, the fold line 17 stops short of the edges 20, 21 and a cut line 22 extends from each end of the fold line 17 into the rear panel section i6a, i6b and terminates at each of the upper and lower edges 20, 21. The cut lines 22 define edge tabs 23, 24 formed out of a part of the rear panel sections ioa, iob at the upper and lower edges 20,21 of the inner frame blank 1.

Each rear panel section i6a, iob has a free edge 25 with tabs 26 that extend away from the free edge 25 in the plane of the rear panel section 16a, ibb.

The inner frame blank 1 shown in Figure 1 is folded into the configuration shown in Figure 2, prior to insertion into a pack 3. This is achieved by first folding the Nank 1 about the central f&d line 5, and a'so about the secondaiy fold lines 6, 7 so that the dividing wall panels 8, 9 face each other and extend outwardly from the plane of the drawing in Figure 1. Next, each end panel 13,14 is folded upwardly, also in a direction out of the plane of Figure i,so that they each extend perpendicular to the front panel sections 4a,4b. Then, each rear panel section i6a, i6b is folded relative to the end wall 13,14 from which it extends about fold line 17, and so that each rear panel section i6a, iob extends perpendicu'ar to each end pane' 13, 14 and is parallel to, and spaced from, thc front pancl scctions 4a, 4b. It will be apprcciatcd that, when a rcar panci scction iôa, iôb is folded relative to its associated end panel 13, 14 about fold lines 17, the central tab 19 and the edge tabs 23, 24, which lie in the plane of the rear panel sections i6a, i6b prior to folding, separate from the rear panel sections i6a, i6b a'ong the cut lines 18,22 so that they remain in the plane of the end pand 13, 14 from which they extend, and so that they protrude beyond the plane occupied by each rear pan& section i6a, i6b that extends perpendicular to each end panel 13, 14.

Once the rear panel sections 16a, i6b have been folded as described above, the locking tabs 26 that extend from the free edge 25 of each rear panel section i6a, i6b, are inserted into the corresponding slots 10, 11 in the dividing wall panels 8,9 to hold the rear panel sections 16a, i6b in position and so that they lie paralld to the front wafi sections 421, 4b. it will be appreciated that, in Figure 2, the locking tabs 26 of one of the rear panel sections i6b have not yet been engaged with their corresponding slots 10, 11 and that the rear panel section i6b has not been fully folded about fold line 17 into a position in which it lies parallel to front panel section 4b.

jo Tn another embodiment, the slots 10,11 in the dividing wafl panels 8,9 are omitted and the tabs 26 are attached to a surface of the corresponding dividing wafi panels 8,9, i.e. by gluing. The tabs 26 may be folded about a fold-line relative to the rear panel sections i6b to enable them to be glued to the dividing wall panels 8,9.

As can be appreciated more easily from Figure 2, each of the dividing wall panels 8,9 have a width (i.e. a dimension extending from the front panel sections a, 4b to the central fold line 5) which is greater than the width of each of the end panels 13, 14 so that, when the inner frame blank 1 is folded and the locking tabs 26 are received in the slots 10,11, the dividing wall panels 8,9 extend beyond each of the rear panel sections i6a, i6b in a direction away from the front panel sections a, 4b.

The width of each of the dividing wall panels 8,9 may be equal to the width of an end panel 13, 14 plus the width of the central tab 18 or an edge tab 23, 24 formed in each rear panel section 16a, i6b so that, when the inner frame blank 1 is folded, the apex between the dividing wall panels 8,9 formed by the central fold line 5 and a tip or edge i8 of the central tab 19 and a tip or edge 22 of the edge tabs 23,24 all lie in the same plane parallel to and spaced from the rear panel sections i6a, i6b.

Whcn the inncr frame 2 has bccn folded as dcscribcd abovc and as almost shown in Figure 2, it may be inserted into a hinged-lid pack 3 having a lid 27 pivotally connected to the rear wall of a base 29 for rotation about a fold Une 30, as shown in the plan view of Figure 3 which shows a pack 3 with the lid 27 open, and the perspective view of Figure 4, which shows the pack 3 with the lid 27 partially open.

As can be seen from Figures 3 and 4, the central tab 18 and the edge tabs 23, 24 extending from the end panels 13, 14, and the part of the dividing wall panels 8, 9 that extends beyond the rear panel sections 16a, i6b, space the rear panel portions 16a, i6b away from the rear wail of the pack 3 and hokis the front panel sections a, 4b against a front wall 30 of the base 29 of the pack 3. A void is therefore formed between the rear panel portions iôa, i6b and a rear wall of the pack 3. The centra' tab 18, edge tabs 23, 24 and the part of the dividing wall panels 8, 9 that extends beyond the rear panel sections i6a, i6b may have a length in the order of -mm so the depth of the void will be substantially the same.

The above arrangement enables a standard size pack to be used to receive two bundles Jo of slim cigarettes. The bundles will be retained snugly within the side-by-side compartments formed by the inner frame 2 and will be pushed towards the front wall of the pack 3, spaced from the rear wall of the pack 3 by the dividing wall panels 8, 9 and the tabs i8, 22, 23 that protrude beyond the rear panel sections i6a, i6b.
