DETAILED DESCRIPTION

[0060] FIGS. 1A-1C and 2A-2B illustrate various views of a container 10 for smoking articles 8 in accordance with the present invention. The container 10 comprises an outer casing 12 which includes a main body 14 and a lid 16. The lid 16 is hingedly connected to the main body 14 by a hinge 30 such that the lid 16 may be moved between an open position and a closed position. FIGS. 1A-1C show the lid 16 in the closed position, whereas FIGS. 2A-2B show the lid 16 in the open position. In the open position, the contents housed within the outer casing 12 may be accessed by a user. In the closed position, the contents of the outer casing 12 are not accessible and the main body 14 and the lid 16 cooperatively define a cuboidal box. The skilled person will appreciate the container 10, or outer casing 12, may also be referred to as a hinged-lid box.

[0061] The main body 14 comprises a plurality panels 18-26 including a front panel 18, a rear panel 20, a bottom panel 22, a first side panel 24 (i.e. left side panel), and a second side panel 26 (i.e. right side panel). These panels 18-26 cooperatively define a main compartment having an opening 28 opposite to the bottom panel 22. The height of the rear panel 20 is greater than the height of the front panel 18 such that the first side panel 24 and the second side panel 26 increase in height towards the rear panel 20.

[0062] The lid 16 comprises a plurality of panels 72-80 including a front panel 72, a rear panel 74, a top panel 76, a first side panel 78 (e.g. a left side panel), and a second side panel 80 (e.g. a right side panel). These panels 72-80 cooperatively define a secondary compartment having an opening opposite to the top panel 76. The height of the front panel 72 is greater than the height of the rear panel 74 such that the first side panel 78 and the second side panel 80 increase in height towards the rear panel 74.

[0063] The lid 16 is connected to the main body 14 by the hinge 30 which is positioned between the rear panel 74 of the lid 16 and the rear panel 20 of the main body 14. The skilled person will appreciate that the hinge 30 is not a separable component of the container 10, but instead is a connecting portion between the rear panel 74 of the lid 16 and the rear panel 20 of the main body 14 about which the lid 16 may be pivoted. That is, the hinge 30 may be described as a fold line or a crease line in the outer casing 12 which is formed from the same material as the main body 14 and the lid 16.

[0064] The outer casing 12 may be made of a cellulose-based material. For example, the outer casing 12 may comprise (or consists of) paper, hemp, or moulded cellulose pulp.

[0065] The outer casing 12 is configured such that the ratio of the height A of the front panel 72 of the lid 16 to the height B of the rear panel 74 of the lid 16 is between 1.8 and 2.2. For example, the ratio A/B may be 2. Advantageously, this size ratio optimises the accessibility of the pouch 32, and provides a larger opening area through which the contents of the outer casing 12 may be accessed, whilst ensuring the lid is not blocked from moving into the closed position. For example, if the height B of the rear panel 74 of the lid 16 is too large, the lid 16 is prevented from opening or closing, but if the height B of the rear panel 74 of the lid 16 is too small, it has been found that the lid may not close properly after multiple openings, and the lid is more likely to be separated from the main body. Moreover, a larger height A of the front panel 72 of the lid 16 provides a larger area for accessing the smoking articles, but a smaller height A of the front panel 72 of the lid 16 reduces the angle about which the lid 16 is required to be pivot in order to open the packet 10.

[0066] The outer casing 12 is further configured such that the ratio of the height B of the rear panel 74 of the lid 16 to the height C of the outer casing 12 when the lid 16 is in the closed position is between 0.15 and 0.19. For example, the ratio B/C may be 0.18. Additionally, the outer casing 12 is configured such that the ratio of the height B of the rear panel 74 of the lid 16 to the width D of the top panel 76 of the lid 16 is between 0.29 and 0.71. For example, the ratio B/D may be 0.67. These ratios further optimise the accessibility of the packet 10. The skilled person will understand that the width of the top panel is the distance between the front panel and the rear panel of the lid.

[0067] A pouch 32 is housed within the outer casing 12. Specifically, the pouch 32 is received within the main compartment of the main body 14 such that a portion of the pouch 32 protrudes through the opening 28 and is completely contained within the outer casing 12 when the lid 16 is moved into the closed position. The pouch 32 is sized to store and collate a plurality of smoking articles 8. That is, the height of the pouch 32 is substantially equal to the height of the smoking articles 8 such that the smoking articles 8 may be securely held within the pouch 32. In one example, the smoking articles 8 may be cigarettes. In other examples, the smoking articles 8 may be heat-not-burn sticks.

[0068] The pouch 32 is substantially cuboidal and includes a front major portion 110, a rear major portion 112, a top minor portion 114, a bottom minor portion 116, a first side portion 118 (e.g. a left side portion), and a second side portion 120 (e.g. a right side portion). The pouch 32 is illustrated in further detail in FIGS. 4A-4C. FIG. 4A shows a schematic view of the front major portion 110 of the pouch 32, FIG. 4B shows a schematic view of the first side portion 118 of the pouch 32, FIG. 4C shows a schematic view of the second side portion 120, and FIG. 4D shows a schematic view of the rear major portion 112 of the pouch 32.

[0069] The pouch 32 comprises a wrapper 122 having a moisture barrier coating 124 formed thereon. Optionally, the wrapper 122 may also have an outer coating 125 formed on an opposite side of the wrapper 122 to the moisture barrier coating 124. The wrapper 122 is folded and sealed to form the substantially cuboidal pouch 32, having an exterior surface 126 and an interior surface 128. In particular, the pouch 32 is sealed by a first fin seal 104 extending along the length of the front major portion 110 of the pouch 32, a second fin seal 106 extending along the length of the top minor portion 114 of the pouch 32, and a third fin seal 108 extending along the length of the bottom minor portion of the pouch 32. The skilled person will understand that a fin seal is a seal formed by an edge portion of the interior surface 128 of the wrapper 122 being sealed to another edge portion of the interior surface 128 of the wrapper 122. In contrast, for example, a lap seal is formed by sealing an edge portion of the interior surface of the wrapper to an edge portion of the exterior surface of the wrapper. Advantageously, unlike lap seals, fin seals prevent the smoking articles 8 contained with the wrapper 122 from being compressed during sealing.

[0070] A tear tape 34 is attached to the pouch 32 and extends around the pouch 32. The tear tape 34 is attached to the interior surface 128 of the pouch 32 but, for illustrative purposes, is shown in FIGS. 4A-4C. The skilled person will appreciate that, in alternative embodiments, the tear tape 34 may be attached to the exterior surface 126 of the pouch 32.

[0071] The tear tape 34 (also known as a tear-off ribbon) is a strip of material which is adhesively coupled to the pouch 32. The tear tape may be pulled by a user to open the pouch 32. In particular, the tear tape 34 is stronger than the pouch 32 such that, when pulled, the pouch 32 is torn open along the length of the tear tape 34. The tear tape 34 may be made of (e.g. orientated) polymers, yarns, and filaments, but preferably is made of a cellulose-based material such as paper.

[0072] As illustrated, the tear tape 34 extends around substantially the entire circumference of the pouch 32 in a transverse direction. That is, the tear tape 34 extends around the front major portion 110, the first side portion 118, the rear major portion 112, and the second side portion 120 of the pouch 32 in a direction that is perpendicular to the length of the pouch 32. However, in alternative embodiments, the skilled person will appreciate that the tear tape 34 may only extend around a portion of the circumference of the pouch 32, e.g. at least 90% of the circumference of the pouch 32.

[0073] The tear tape 34 is arranged to extend through the first fin seal 104 of the front major portion 112 of the pouch 32, to expose a tear tab 35 of the tear tape 34 which may be pulled by a user. Advantageously, this increases the ease of manufacturability of the pouch 32. The tear tape 34 may be attached to the pouch 32 such that only a single layer of tear tape 34 protrudes through the first fin seal 104, thereby reducing the bulkiness of the pouch 32.

[0074] As best illustrated in FIGS. 1A and 1B, the bottom edge 36 of the tear tape 34 is aligned level with the hinge 30 of the outer casing 12. In other words, the tear tape 34 and the hinge 30 are arranged with respect to one another such that the bottom edge 36 of the tear tape 34 is positioned at substantially the same vertical height (i.e. at substantially the same position along the length of the container 10) as the hinge 30. The hinge 30, or top edge of the rear panel 20 of the main body 14, therefore lies in the same plane as the bottom edge 36 of the tear tape 34. In this way, when the lid 14 is in the open position, it is ensured that the tear tape 34 is not trapped between the pouch 32 and the main body 14 of the outer casing 12. Hence, the ease of removal of the tear tape 34, and thus opening of the pouch 32, is improved. Additionally, by located the bottom edge 36 of the tear tape 34 level with the hinge 30, as opposed to above the hinge 30, the hinge 30 (i.e. the top edge of the rear panel 20 of the main body 14) provides a guiding edge along which the tear tape 34 may be pulled. This further improves the ease of opening of the pouch 32 for a user.

[0075] Of course, the skilled person will appreciate that, in other embodiments, the bottom edge 36 of the tear tape 34 may not be positioned at the same level as the hinge 30. For example, the tear tape 34 may be positioned adjacent and above the hinge 30, e.g. the bottom edge of the tear tape may be positioned 0.5 mm, 1 mm, 1.5 mm, 2 mm, or 3 mm above the hinge, and/or the tear tape 34 may be positioned above the hinge 30 such that the distance between the bottom edge 36 of the tear tape 34 and the hinge 30 is less than the width of the tear tape 34. This arrangement similarly ensures that the tear tape 34 is accessible for users.

[0076] It is further preferable for the tear tape 34 to be arranged closer to the hinge 30 than the top minor portion 114 of the pouch 32. Advantageously, this configuration reduces the chance of the pouch 32 being ripped across the top minor portion 114, and instead promotes a clean partitioning of the pouch 32 around its circumference.

[0077] A line of weakening 64 is formed in the exterior surface 126 of the pouch 32. The line of weakening 64 enables the pouch 32 to be easily ripped along the line of weakening 64 when the tear tape 34 is pulled by a user. In one example, the line of weakening 64 may comprise a line of indentations, cuts, or scores. The line of weakened may be formed by laser scoring or mechanical cutting or indentation of the wrapper 122. The line of weakening 64 extends partially through the wrapper 122 (and/or extends partially or entirely through the outer coating 125, if present), and does not extend through the moisture barrier coating 124. This form of line of weakening may be referred to as a kiss-cut line. Advantageously, as the line of weakening 64 does not extend all the way through the pouch 32, the pouch 32 remains sealed to the external environment. In another example, the line of weakening 64 may comprise a chemically, radiatively, or mechanically weakened portion.

[0078] The line of weakening 64 is aligned adjacent with the bottom edge 36 of the tear tape 34 such that application of a pulling force to the tear tape 34 results in the pouch 32 being partitioned along the line of weakening 64. Specifically, the line of weakening 64 extends around the pouch 32, e.g. along the front major portion 110, the first side portion 118, the rear major portion 112, and the second side portion 120 of the pouch 32 in a direction that is perpendicular to the length of the pouch 32. Ideally, the line of weakening 64 is situated level with the bottom edge 34 of the tear tape 34 and/or the hinge 30. However, as illustrated in FIGS. 4A-4C, it is possible for the tear tape 34 to be slightly below the tear tape 34. In particular, the tear tape 34 may be up to 3 mm below the bottom edge 36 of the tear tape 34 whilst providing reliable opening of the pouch 32 along the line of weakening 64.

[0079] FIG. 5A shows a cross-sectional view of the wrapper 122 and the moisture barrier coating 124 which form the pouch 32. As illustrated, the tear tape 34 is attached to the interior surface 128 of the pouch 32 and the line of weakening 64 is formed on the exterior surface 126 of the pouch. The moisture barrier coating 124 is formed on (or forms) the interior surface 128 of the pouch 32.

[0080] FIG. 5B shows a cross-sectional view of the pouch 32 in an alternative embodiment, in which the pouch 32 further comprises the outer coating 125 formed on an opposite surface of the wrapper 122 to the moisture barrier coating 124. That is, the outer coating 125 is formed on (or forms) the exterior surface 126 of the pouch 32. The outer coating 125 may be configured to increase the tensile strength of the pouch 32 and/or alter the appearance of the pouch 32, such as increasing its opacity. In this example, the line of weakening 64 extends entirely through the outer coating 125 and partially through the wrapper 122. In alternative examples, the line of weakening may extend partially though the outer coating 125.

[0081] The thickness of the pouch 32 (i.e. the wrapper 122 and the moisture barrier coating 124 and optionally the outer coating 125) may be 65 to 85 microns. The density of the pouch 32 (i.e. the wrapper 122 and the moisture barrier coating 124 and optionally the outer coating 125) may be 50 to 92 grams per square metre. For example, the density of the pouch 32 may be 50 to 85 grams per square metre.

[0082] The wrapper 122 is made of a cellulose-based material, such as paper, hemp, moulded cellulose pulp, virgin fibre pulp or tobacco dust with paper. The moisture barrier coating 124 prevents the ingress of moisture through the wrapper 122, thereby protecting the smoking articles 8 contained within the pouch 32. Advantageously, by using a cellulose-based wrapper 122 with a moisture barrier coating 124, as opposed to a wrapper containing plastic or metal, the biodegradability and sustainability of the package 10 is improved without reducing the seal quality.

[0083] In one example, the moisture barrier coating 124 may be a heat sealable coating or film. In another example, the moisture barrier coating 124 may be a water-based lacquer. In another example, the moisture barrier coating 124 may be a hot melt adhesive.

[0084] The moisture barrier coating 124 may also reduce or prevent the transfer of oxygen, air, flavourings, and/or menthol through the pouch 32.

[0085] As a result of the fin sealing, and the properties of the moisture barrier coating 124, the pouch 32 (i.e. the wrapper 122, the moisture barrier coating 124, and optionally the outer coating 125) may have a water vapour transmission rate of 0-10 g/m.sup.2/day (at 23 C., 50% RH) and an oxygen transmission rate of <10 ccm/m.sup.2/day (at 23 C., 50% RH). For example, the pouch 32 may have a water vapour transmission rate of 2-10 g/m.sup.2/day (at 23 C., 50% RH).

[0086] The wrapper 122, moisture barrier coating 124, and optionally the outer coating 125 (i.e. the blank 130 as discussed further below) may be manufactured using flexographic or gravure printing.

[0087] Exemplary material specifications for the pouch 32 are provided in the following table:

[0088] As seen in FIGS. 1A-1C, the container 10 further comprises a frame 92 (which may be referred to as an inner frame) which is located between the pouch 32 and the main body 14 of the outer casing 12. The frame 92 is a folded element including a front section 94, a first side section 96 (e.g. a left side section), and a second side section 98 (e.g. a right side section). FIG. 6 illustrates the frame 92 in unfolded form. The first side section 96 and the second side section 98 are connected to the opposing sides of the front section 94 by respective fold lines. When the container 10 is constructed, the first side section 96 and the second side section 98 are folded approximately 90 degrees about the respective fold lines and the frame 92 is arranged between the pouch 32 and the outer casing 12 such that the front section 94, the first side section 96 and the second side section 98 of the frame 92 are arranged adjacent to (i.e. interface with) each of the front panel 18 of the main body 14 and the front major section 110 of the pouch 32, each of the first side panel 24 of the main body 14 and the first side section 118 of the pouch 32, and each of the second side panel 26 of the main body 12 and the second side section 120 of the pouch 32 respectively.

[0089] Advantageously, the presence of the frame 92 improves the stiffness of the container 10, thereby providing enhanced protection and support of the smoking articles 8 contained with the pouch 32. Additionally, the frame 92 helps to ensure reliable closing of the lid 16, for example using the click-lock functionality described below.

[0090] As best illustrated in FIGS. 1A and 1B, the bottom edge 36 of the tear tape 34 is aligned level with the top edge 100 of the front portion 94 of the frame 92. In other words, the tear tape 34 and the frame 92 are arranged with respect to one another such that the bottom edge 36 of the tear tape 34 is positioned at substantially the same vertical height (i.e. at substantially the same position along the length of the container 10) as the top edge 100 of the front section 94 of the frame 92. The top edge 100 of the frame 92 therefore lies in the same plane as the bottom edge 36 of the tear tape 34. In this way, when the lid 16 is in the open position, it is ensured that the tear tape 34 is not trapped between the pouch 32 and the frame 92. Hence, the ease of removal of the tear tape 34, and thus opening of the pouch 32, is improved. Additionally, by locating the bottom edge 36 of the tear tape 34 substantially level with the top edge 100 of the frame 92, as opposed to above the top edge 100 of the frame 92, the top edge 100 of the frame 92 provides a further guiding edge along which the tear tape 34 may be pulled, which further improves the ease of opening of the pouch 32 for a user.

[0091] The skilled person will appreciate that as the hinge 30, the bottom edge 36 of the tear tape 34, and the top edge 100 of the frame 92 are all positioned in the same plane, the tear tape 34 may be reliably pulled around the entire circumference of the pouch 32 without obstruction.

[0092] Of course, the skilled person will also appreciate that, in alternative embodiments, the top edge 100 of the frame 92 may not be exactly level with the hinge 30 and/or the bottom edge 36 of the tear tape 34. In particular, it remains advantageous to arrange the frame 92 such that the top edge 100 of the frame 92 is below the tear tape 34, e.g. 0.5 mm, 1 mm, 1.5 mm or 2 mm below the bottom edge 36 of the tear tape 34, as this configuration also ensures that the tear tape 34 is not trapped between the pouch 32 and the frame 92.

[0093] A cut-out 102, which may also be referred to as a recessed portion, is formed in the top edge 100 of the front section 94 of the frame 92. The cut-out 102 is formed by removing a portion of material from the top edge 100 of the front section 94 of the frame 92. Preferably, the cut-out 102 extends a distance of up to 5 mm. For example, the cut-out 102 may extend 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm below the top edge 100 of the frame 92.

[0094] The cut-out 102 is centrally positioned along the top edge 100 of the front section 94 of the frame 92, and preferably has a width of at least 50% of the width of the front section 94 of the frame 92.

[0095] Advantageously, the presence of the cut-out 102 improves the accessibility to the smoking articles 8 contained with the pouch 32 when the pouch 32 is opened, without adversely affecting the stiffening effect provided by the frame 92.

[0096] The front section 94 of the frame 92 further comprises a tongue 66, which may also be referred to as a tab, which is arranged to protrude away from the surface of the front section 94 of the frame 92. A complementary recess 68 is provided within the secondary compartment of the lid 16 on the front panel 72 of the lid 16. When the lid 16 is in the closed position, the tongue 66 is configured to engage with the recess 68 such that the lid 16 is held in the closed position. A threshold force applied by a user is required to disengage the tongue 66 from the recess 68 such that the lid 16 is moved into the open position. This may be referred to as a click-lock mechanism.

[0097] The first side section 96 and the second side section 98 of the frame 92 are shaped such that the lid 16 is not blocked from being moved into the closed position. In particular, the first side section 96 and the second side section 98 have upper edges which slant down (e.g. curve down) from the top edge 100 of the front section 94 of the frame 92. This means that the lid 16 does not impinge on the first side section 96 and the second side section 98 of the frame 92 when being moved into the closed position. Of course, the skilled person will appreciate that the specific shape of the frame 92 illustrated in FIG. 8 is not essential and may be varied. For example, the first side section 96 and the second side section 98 of the frame 92 may have flat upper edges.

[0098] The frame 92 may be made from a cellulose-based material, such as paper, hemp, or moulded cellulose pulp. Advantageously, the frame 92 may have a higher rigidity than the pouch 32. For example, the frame 92 may have a density of 130 to 200 grams per square metre.

[0099] FIGS. 3A-3C illustrate the pouch 32 in an opened state in which the tear tape 34 has been pulled to remove a top section 38 of the pouch 32 from a bottom section 40 of the pouch 32, thereby exposing the smoking articles 8 contained within the pouch 32. For ease of illustration, reference numerals for features previously labelled in FIGS. 1A-1C have been omitted from FIGS. 3A-3C. A stiffening element 82 is located between the pouch 32 and the smoking articles 8 contained within the pouch 32. The stiffening element 82 is exposed when the pouch 32 is opened.

[0100] The stiffening element 82 is a folded element comprising a front section 84, a first side section 88 (e.g. a left side section), and a second side section 90 (e.g. a right side section). FIG. 7 illustrates the stiffening element 82 in unfolded form. The first side section 88 and the second side section 90 are connected to the opposing sides of the front section 84 by respective fold lines. When the container 10 is constructed, the first side section 88 and the second side section 90 are folded approximately 90 degrees about the respective fold lines and the stiffening element 82 is arranged between the pouch 32 and the smoking article 8 such that the front section 84, the first side section 88 and the second side section 90 of the stiffening element 82 are arranged adjacent to (i.e. interface with) the front major portion 110 of the pouch 32, the first side portion 118 of the pouch 32, and the second side portion 120 of the pouch 32 respectively.

[0101] Advantageously, the presence of the stiffening element 82 further improves the stiffness of the container 10, thereby further enhancing the protection and support of the smoking articles 8 contained with the pouch 32, whilst ensuring that the tear tape 34 remains accessible to a user.

[0102] The height of stiffening element 82, and in particular the height of the first side section 88 and the second side section 90 of the stiffening element 82, is equal to the height of the pouch 32. This arrangement provides optimal protection and support for the smoking articles 8 contained with the pouch 32.

[0103] The stiffening element 82 has a top edge 85 in which a cut-out 86 is formed. That is, a portion of material is removed along the top edge 85 of the front section 84 of the stiffening element 82 to form the cut-out 86, which may also be referred to as a recessed portion.

[0104] The cut-out 86 extends below the bottom edge 36 of the tear tape 34 and/or the line of weakening 64. In this way, when the tear tape 34 is pulled to open the pouch 32, the smoking articles 8 are additionally exposed through the cut-out 86, allowing a user to easily grasp and remove the smoking articles 8. Preferably, the cut-out 86 extends below the top edge 85 of the stiffening element 82 a distance of 10% to 30% of the height of the front section 84 of the stiffening element 82. For example, the cut-out may extend 10 mm, 11 mm, 12 mm, 13 mm, 14 mm or 15 mm below the top edge 85 of the stiffening element 82.

[0105] The cut-out 86 is centrally positioned along the top edge 85 of the front section 84 of the stiffening element 82, thereby providing optimal access to the smoking articles 8. The cut-out 86 may have a width of at least 50% of the width of the front section 84 of the stiffening element 82.

[0106] The stiffening element 82 may be made from a cellulose-based material, such as paper, hemp, or moulded cellulose pulp. Advantageously, the stiffening element 82 may have a higher rigidity than the pouch 32. For example, the stiffening element 82 may have a density of 130 to 200 grams per square metre.

[0107] The pouch 32 may be formed from a blank 130 comprising the wrapper 122 and the moisture barrier coating 124 (and, in some embodiments, the outer coating 125). The blank 130 is illustrated in FIG. 8.

[0108] The blank 130 comprises a plurality of panels 136-152 separated by fold lines. The plurality of panels 136-152 include a first front blank panel 132 and a second front blank panel 134 for cooperatively forming the front major portion 110 of the pouch 32. The plurality of panels 136-152 further include a rear blank panel 136 for forming the rear major portion 112 of the pouch. The plurality of panels 136-152 further include a first top blank panel 138, a second top blank panel 140, and a third top blank panel 142 for cooperatively forming the top minor portion 114 of the pouch 32. The plurality of panels 136-152 further include a first bottom blank panel 144, a second bottom blank panel 146, and a third bottom blank panel 148 for cooperatively forming the bottom minor portion 116 of the pouch 32. The plurality of panels 136-152 further include a first side blank panel 150 and a second side blank panel 152 for forming the first side portion 118 and the second side portion of the pouch 32 respectively.

[0109] The blank 130 comprises a first longitudinal fin tab 154 and a second longitudinal fin tab 156, a top transverse fin tab 158, and a bottom transverse fin tab 160 which form the border (i.e. the edge portions) of the blank 130.

[0110] The blank 130 (and thus also panels 136-152 and tabs 154-160) may be described as having two surfaces: an exterior surface and an opposed interior surface. When formed, the exterior surface 126 of the pouch 32 corresponds to the exterior surface of the blank 130 and the interior surface 128 of the pouch 32 corresponds to the interior surface of the blank 130. The moisture barrier coating 124 is formed on the interior surface of the blank 130 and the outer coating 125 is optionally formed on the exterior surface of the blank 130.

[0111] The tear tape 34 is attached to the interior surface of the blank 130, and extends in a straight line across the second longitudinal fin tab 156, the first front blank panel 132, the second side blank panel 152, the rear blank panel 136, the first side blank panel 150, the second front blank panel 134, and the first longitudinal fin tab 154. Optionally, the tear tape 34 may only extend over one of the first longitudinal fin tab 154 and the second longitudinal fin tab 156. In this way, when the pouch 32 is constructed, only a single layer of the tear tape 34 extends through the first fin seal 104, thereby reducing the bulkiness of the pouch 32.

[0112] The line of weakening 64 is formed in the exterior surface of the blank 130, and extends parallel and adjacent to the bottom edge 36 of the tear tape 34, as previously described.

[0113] To form the pouch 32 from the blank 130, each of the panels 136-152 and tabs 154-160 are folded about the respective fold lines that connect them with other panels 136-152 and tabs 154-160 of the blank 130. Each of the panels 136-152 and tabs 154-160 are folded about the respective fold lines at approximately 90 degrees. The first longitudinal fin tab 154 is sealed to the second longitudinal fin tab 156 along the interior surface, thereby forming the first fin seal 104. The top transverse fin tab 158 is sealed to itself along the interior surface, thereby forming the second fin seal 106. The bottom transverse fin tab 160 is sealed to itself along the interior surface, thereby forming the third fin seal 108. Each fin seal 104-108 may be sealed using a suitable adhesive.

[0114] In the assembled pouch 32, e.g. as illustrated in FIGS. 4A-4C, the first fin seal 104, second fin seal 106 and the third fin seal 108 are typically folded against (e.g. arranged to lie substantially flat against) the front major portion 110, the top minor portion 114, and the bottom minor portion 116 of the pouch 32 respectively. The first fin seal 104 is typically folded against the front major portion 110 prior to sealing of the second fin seal 106 and the third fin seal 108.

[0115] The fin seals 104-108 are effective in sealing the pouch 32 from the external environment. The smoking articles 8 may be provided within the pouch 32 before or during the folding and sealing process.

[0116] Once the pouch 32 has been formed from the blank 130, the tear tab 35 of the tear tape 34 is arranged to protrude through the first fin seal 104 such that it may be pulled by a user.

[0117] FIG. 9 illustrates a partially constructed form of the pouch 32 in which only the first fin seal 104 has been formed. The first fin seal 104 has a base 105 about which the first fin seal 104 may be pivoted. The base 105 corresponds to the fold lines of the blank 130 connecting the first longitudinal fin tab 154 and the second longitudinal fin tab 156 to the second front blank panel 134 and the first front blank panel 132 respectively. That is, the base 105 is the pivotal axis of the first fin seal 104 which extends along the length of the front major portion 110 of the pouch 32. In the state illustrated, the first fin seal 104 protrudes away from the pouch 32, and has not yet been folded against the front major portion 110 of the pouch 32.

[0118] To form the second fin seal 106 and the third fin seal 108, the top transverse fin tab 158 is sealed to itself along its interior surface and the bottom transverse fin tab 160 is sealed to itself along its interior surface.

[0119] The top transverse fin tab 158 and the bottom transverse fin tab 160 each comprise side segments 162. Due to geometrical constraints, and in order to prevent any material protruding from the second fin seal 106 and the third fin seal 108, the side segments 162 are tucked into the second fin seal 106 and the third fin seal 108 respectively and sealed therein. That is, the side segments 162 are folded, e.g. in a concertina arrangement, and sealed between the interior surfaces of the top transverse fin tab 158 and the bottom transverse fin tab 160 respectively, as illustrated in FIG. 10.

[0120] In particular, FIG. 10 illustrates the pouch 32 in a state wherein the first fin seal 104 has been sealed and folded against the front major portion 110 of the pouch 32, and the second fin seal 106 has been subsequently formed and sealed. For ease of illustration, the third fin seal 108 is not shown in FIG. 10, but the skilled person will understand that the third fin seal 108 is similarly configured to the second fin seal 106 Mutatis mutandis.

[0121] As a consequence of folding and interposing the side segments 162 within the second fin seal 106, two bulky regions 164 are formed adjacent the first side portion 118 and the second side portion 120 of the pouch 32 respectively. The bulky regions 164 consist of four layers of the wrapper 122. In contrast, away from the first side portion 118 and the second side portion 120, i.e. towards the centre of the second fin seal 106, only two layers of the wrapper 122 are present along the second fin seal 106.

[0122] The first fin seal 104 is arranged such that the first fin seal 104 does not overlap with either of the bulky regions 164, i.e. the first fin seal 104 does not overlap with the regions of the second fin seal 106 in which the side segments 162 are present. In other words, the first fin seal 104 is sized and positioned such that, when the first fin seal 104 is folded against the front major portion 110 of the pouch 132, the first fin seal 104 only overlaps with two layers of the wrapper 122 of the second fin seal 106 (i.e. two layers of the top transverse fin tab 158). The first fin seal 104 does not overlap with the side segments 164.

[0123] The first fin seal 104 is folded towards the first side portion 118 of the pouch 32. The skilled person will appreciate that, as the side segments 162 are folded at their midpoint before being sealed within the second fin seal 106, the length of each bulky region 164 is equal to half the width X.sub.4 of the first side portion 118 (or second side portion 120) of the pouch 32. Hence, to ensure that overlap with the bulky regions 164 is avoided, the first fin seal 104 is configured such that the distance X.sub.2 between the base 105 of the first fin seal 104 and the first side portion 118 of the pouch 32 is equal to or greater than the sum of the width X.sub.1 of the first fin seal 104 and half the width X.sub.4 of the first side portion 118 of the pouch 32. Additionally, the distance X.sub.3 between the base 105 of the first fin seal 104 and the second side portion 120 of the pouch 32 is equal to or greater than half the width X.sub.4 of the second side portion 120 of the pouch 32. That is, X.sub.1+0.5X.sub.4X.sub.2 and 0.5X.sub.4X.sub.3.

[0124] Advantageously, by arranging the first fin seal 104 such that overlap with more than two layers of the wrapper 122 along the second fin seal 106 is avoided, the bulkiness of the pouch 32 is reduced and the seal quality of the second fin seal 106 is improved. In particular, when the second fin seal 106 is sealed, the wrapper 122 is squeezed and compressed along the length of the second fin seal 106. Hence, if the first fin seal 104 overlaps with the bulky region 164 when the first fin seal 104 is folded against the pouch 32, six layers of the wrapper 122 would be squeezed and compressed at the bulky region 164, thereby resulting in a poor quality seal of the second fin seal 106. Hence, by avoiding overlap between the first fin seal 104 and the bulky regions 164, and ensuring that there are a maximum of four overlapping layers of wrapper 122 at all locations along the second fin seal 106, the seal quality of the second fin seal 106 is significantly improved. Similar comments apply with respect to the third fin seal 106 mutatis mutandis.
