Abstract
A container for smoking articles has an outer housing including a hinged lid rotatable between open and closed positions. An inner package has an access opening through which smoking articles can be removed. The access opening can be covered by a reclosable flap when the hinged lid is in the closed position. With the lid in the closed position, the reclosable flap forms an overlap region with a surface of the inner package that extends around the periphery of the access opening. An outer surface of the reclosable flap is attached to a first lid panel of the hinged lid. When the hinged lid is moved from the closed position to the open position, a pivoting movement is provided about the first lid panel whereby the first lid panel pivots against the inner package along a pivot line, and wherein non-adhering region of the overlap region includes the pivot line.

DETAILED DESCRIPTION
[0105] The hinged lid container 1 shown in
[0106] The box 2 has a box front wall, a box left side wall, a box right side wall, a box back wall, and a box bottom wall. The upper side of the box 2 is open, to provide an upper opening through which the cigarettes can be removed.
[0107] The lid 3 has a lid front wall, a lid left side wall, a lid right side wall, a lid back wall and a lid top wall. When the container 1 is closed, the free edges of the walls of the lid 3 abut the free edges of the walls of the box 2 along a line of abutment. In the closed position, the walls of the lid 3 therefore form extensions of the corresponding walls of the box 2 to define the walls of the outer housing 1.
[0108] The inner package 5 includes an access opening 6 through which the cigarettes can be removed. When the inner package 5 of cigarettes is in place within the box 2, the access opening 6 is positioned at the open, upper end of the box 2. The access opening 6 includes a cut line 57 that defines a flap 58 that covers the access opening 6. The flap 58 is movable to cover and uncover the access opening 6 and thus prevent or allow access to the cigarettes. A line of weakness may be provided instead of the cut line 57 so that the flap 58 separates from the inner package 5 only upon first opening of the container 1. Alternatively, the access opening 6 is a cut-out 59 (see
[0109] An inner frame 4 (formed from a blank 40 shown in
[0110] A reclosable flap 8 is attached to the outer surface of the inner package 5 so that it can cover the access opening 6 in the inner package 5. The reclosable flap 8 is affixed to the inner package 5 at an upper, back edge of the inner package 5, which provides a hinge line 7 about which the reclosable flap 8 can be pivoted to open and close the access opening 6. The reclosable flap 8 extends beyond the periphery of the access opening 6 and is also affixed to the inner package flap 58.
[0111] The reclosable flap 8 in this embodiment is a self-adhesive label. The label 8 includes a resealable adhesive on its inner surface, which overlies a portion of the inner package 5 around the periphery of the access opening 6. When the lid 3 is in the closed position the resealable adhesive affixes the adhesive label 8 to the inner package 5.
[0112] The resealable adhesive may also be used to affix the reclosable flap 8 to the inner package flap 58, although it is preferred to use a permanent adhesive to prevent the inner package flap 58 from peeling off the label 8 after a number of openings. The resealable adhesive may be a pressure sensitive adhesive. The permanent adhesive may be a UV-cured pressure sensitive adhesive.
[0113] The permanent adhesive may be provided inside a frame of resealable adhesive within the periphery 57 of the access opening 6, as shown in
[0114] In an alternative embodiment where the access opening 6 is a cut-out 59, the label 8 is substantially free of adhesive within the periphery 57 of the access opening 6.
[0115] As shown in
[0116] The inner surface of the reclosable flap 8 includes an overlap region where, with the lid 3 in the closed position, the reclosable flap 8 is provided next to the inner package 5, around the periphery 57 of the access opening 6. The inner surface of the reclosable flap 8 includes a first portion 14 having a resealable adhesive to releasably affix the inner package 5 and the reclosable flap 8 and a second portion 16 which is substantially free of adhesive. In this embodiment the second portion 16 of the overlap region is provided adjacent the hinge line 7 of the reclosable flap 8 on the top wall of the inner package 5. In the closed position, the first portion 14 of the reclosable flap 8 is provided next to a sealing portion 15 of the inner package 5 so that the respective walls adhere. Of course, in another embodiment the resealable adhesive may be provided on the sealing portion 15 of the inner package 5, rather than the reclosable flap 8. In the closed position, the second portion 16 of the reclosable flap 8 is provided next to a corresponding portion of the inner package 5 on the periphery 57 of the access opening 6, but no adhesion occurs between the two surfaces. The respective surfaces may lie very close together, or be in direct contact, but the absence of sealing engagement means that fluid exchange may be possible between the interior of the inner package 5 and the external environment. This creates a breathable seal for the access opening 6, which can help to preserve the tobacco in the cigarettes under certain atmospheric conditions.
[0117] In this embodiment the second portion 16 of the reclosable flap 8, which is substantially free of adhesive, is provided adjacent the hinge line 7. It has been found that tobacco crumbs preferentially gather at hinge line 7, and an absence of adhesive in this region means that it is possible to reduce the number of tobacco crumbs that are visible in normal use.
[0118] By providing the second portion 16 of the reclosable flap 8 adjacent the hinge line 7 it is also possible to reduce adhesion that might otherwise prevent or restrict the reclosable flap 8 from opening fully in the lid open position. This arrangement may advantageously improve access to the cigarettes in the inner package 5.
[0119]
[0120]
[0121] As can be seen in
[0122] It has been found advantageous to provide resealable adhesive on the first portion 14 of the reclosable flap 8 on at least the top surface 82 and the front surface 83. This can allow the reclosable flap 8 to wrap around the top, front edge of the inner package 5 in a reliable way, which can help to ensure that the reclosable flap 8 is positioned correctly when the lid 3 is moved from the open to the closed position. In this embodiment, the first portion 14 of the reclosable flap 8 has a length l.sub.1 of around 14 mm, extending toward the hinge line 7, in a direction substantially perpendicular to the hinge line 7, along the top surface 82.
[0123] In another embodiment, not shown, the first portion 14 of the reclosable flap 8 has a length l.sub.1 of around 9 mm, extending toward the hinge line 7, in a direction substantially perpendicular to the hinge line 7, along the top surface 82. In this same embodiment, the second portion 16 of the reclosable flap 8, which is substantially free of resealable adhesive, has a length l.sub.2 of around 9 mm, extending from the hinge line 7, in a direction substantially perpendicular to the hinge line 7, along the top surface 82.
[0124] Thus, the resealable adhesive extends about the lower edge of the periphery 57 of the access opening 6, about the left and right edges of the periphery 57 of the access opening 6 in the front wall of the inner package 5 and about a portion of the left and right edges of the periphery 57 of the access opening 6 in the top wall of the inner package 5.
[0125] The outer surface of the free end 9 of the reclosable flap 8 is provided with a permanent adhesive (not shown) for attachment to the inner surface of the lid 3.
[0126] In another embodiment, not shown, the inner package 5 may be provided with a release agent such that when a reclosable flap 8, substantially comprising an adhesive layer, overlies the inner package 5, the reclosable flap 8 will not adhere to the inner package 5 in that region.
[0127]
[0128]
[0129] In this arrangement, and in the closed position of the hinged lid 3, the first portion 14 of the reclosable flap 8 extends at least 5 mm away from a front, top edge of the inner package 5, in a perpendicular direction along the front surface 83 of the reclosable flap 8. It has been found that this can help the reclosable flap 8 to wrap around the front, top edge of the inner package 5 to improve positioning of the reclosable flap 8 against the inner package 5 when the hinged lid 3 is in the closed position.
[0130] In the closed position of the lid 3, the second portion 16 of the reclosable flap 8, which is substantially free of adhesive, is next to the inner package 5 by the periphery 57 of the access opening 6. The absence of a sealing engagement in this region means that a breathable seal is created, which can allow oxygen exchange between the interior of the inner package 5 and the external environment. A further advantage is created because the absence of any resealable adhesive at the connecting portion 9 of the label 8 to the lid 3 improves the ease with which the container 1 can be opened. During a normal opening operation, the hinged lid 3 pulls the reclosable flap 8 away from the inner package 5 such that they peel apart, where they have adhered. During opening, the second portion 16 of the reclosable flap 8 moves easily away from the inner package 5 since it is not adhered. This eases initial opening of the hinged lid 3, and improves the ease with which the first portion 14 can be peeled away, once this peeling process has begun.
[0131] The access opening 6 has a curved lower periphery 57 in this embodiment, which corresponds with a curved surface in the second portion 16 of the reclosable flap 8. It has been found that this shape of access opening 6 can improve the ease with which users access the cigarettes 11. Although only represented in this embodiment, the curved shape of the access opening 6 in the lower periphery 57 can be implemented in any other embodiment of the invention.
[0132] In an alternative embodiment, not shown, the second portion 16 of the reclosable flap 8 may extend across the full width of the flap 8. Therefore, the central section of the second portion 16 of the reclosable flap 8 may lie behind the inner package flap 58, in use. Thus, only the section of the second portion 16 that projects outside of the inner package flap 58 is exposed in normal use.
[0133]
[0134] In this arrangement, the reclosable flap 8 advantageously avoids tobacco crumbs from sticking to the flap 8 adjacent the hinge line 7, promotes wide opening of the lid 3, and improves the ease with which the lid 3 opens. Further, the container 1 promotes preservation of tobacco by enabling oxygen exchange between the interior of the inner package 5 and the external environment.
[0135] In an alternative embodiment, not shown, the third portion 18 includes a lower portion of the periphery 57 of the access opening 6 in a similar embodiment as the second portion 16 of the label 8 of the third embodiment of the invention, represented in
[0136] The second portion 16 of the reclosable flap 8 has been described as being substantially free of resealable adhesive. However, at least some of the advantageous effects described herein may be realised by providing the second portion 16 with a reduced adhesiveness, in comparison to the first portion 14.
[0137] The outer surface of the label 8 is permanently affixed at its free end 9 to the first lid inner front panel 32, for example with a permanent adhesive, such as a hot melt adhesive or a strip of adhesive carried by a carrier material. As a result, movement of the lid 3 causes movement of the label 8 and of the first lid inner front panel 32, which rotates relatively to the lid outer front panel 31.
[0138] In this arrangement, the second portion 16 of the reclosable flap 8, which is substantially free of resealable adhesive, is provided at the free end 9 of the label 8 and around part of the periphery 57 of the access opening 6, similarly to the third embodiment of the invention. The first portion 14 of the reclosable flap 8, which is provided with resealable adhesive, extends from the second portion 16 to the hinge line 7. As can be appreciated in
[0139] The second portion 16 of the reclosable flap 8, which is substantially free of resealable adhesive, is provided on an inner surface of the free end 9 of the reclosable flap 8. The area of the second portion 16 of the reclosable flap 8 is larger than the area of the reclosable flap 8 that overlaps the first lid inner front wall 32. In particular, the length of the second portion 16, measured from the free end 9 along the reclosable flap 8, is at least 1 mm greater than the length of the overlapping portion of the reclosable flap 8 to the first lid inner front panel 32, measured from the free end 9 along the reclosable flap 8. This arrangement means that the second portion 16 of the reclosable flap 8, which is substantially free of adhesive, is provided between the edge 32 of the first lid inner front wall 32 and the inner package 5 when the two are brought into contact.
[0140] In order to access the cigarettes within the inner package 5, the hinge lid 3 is moved from the closed position to the open position shown in
[0141] Therefore, the container 1 of the present embodiment provides a two-stage opening of the lid 3. In a first stage, the free end 9 of the reclosable flap or label 8 is pivoted about the inner package 5. In a second stage, the reclosable flap or label 8 is peeled off the inner package 5, thereby uncovering the access opening 6 in the inner package 5. In the first stage the reclosable flap or label 8 preferably does not even partially uncover the access opening 6.
[0142] In order to close the container 1, the hinge lid 3 is moved from the open position to the closed position. As the lid 3 is moved from the open position, the label 8 is rolled over the inner package 5, thereby covering the access opening 6 in the inner package 5. The first lid inner front panel 32 extends the label 8 reach in the open position and tensions the label 8 during lid closing, thereby ensuring the precise repositioning of the adhesive label 8 against the inner package 5. The edge 32 of the first lid inner front panel 32 comes into contact with the inner package 5 at a stop motion position shown in
[0143] Therefore, the container 1 of the present embodiment provides a two-stage closing of the lid 3. In a first stage, the reclosable flap or label 8 is rolled over the inner package 5, thereby covering the access opening 6 in the inner package 5. In a second stage, the free end 9 of the reclosable flap or label 8 is pivoted about the inner package 5.
[0144] The lid 3 is therefore movable about the box 2 between open and closed positions through an intermediate, stable position shown in
[0145] This pivotal contact occurs about a pivot line in the second portion 16 of the reclosable flap 8. The absence of any adhesive is considered advantageous in this arrangement as it prevents any interference in the pivoting movement. The reverse occurs as the lid 3 is moved from the open position towards the closed position whereby the edge 32 can pivot along a pivot line in the second portion 16 of the reclosable flap 8.
[0146] A low friction interaction may be provided between the reclosable flap 8 and the inner package 5 in areas where there is an absence of adhesive. This may cause some movement of the pivot line of the edge 32 during the opening and/or closing of the lid 3. Advantageously the edge 32 is provided in the second portion of the reclosable flap 8 for all possible positions of the pivot line.
[0147] In the embodiment of
[0148]
[0149]
[0150] The box portion 20 comprises a box front panel 21, box outer and inner left side panels 22, 22, box outer and inner right side panels 23, 23, a box back panel 24, a box bottom panel 25 and two box gluing flaps 26. Although in
[0151] In order to assemble the box 2 of the outer housing 1, the box gluing flaps 26 are glued to the box bottom panel 25 to form the box bottom wall. To form the box left side wall, the box inner left side panel 22 is glued to the box outer left side panel 22. The box inner right side panel 23 is glued to the box outer right side panel 23 to form the box right wall.
[0152] The lid portion 30 comprises a lid outer front panel 31, a lid inner front panel 32, lid outer and inner left side panels 34, 34, lid outer and inner right side panels 35, 35, a lid back panel 36, a lid top panel 37 and two lid gluing flaps 38. The lid back panel 36 is hingedly connected (e.g. by a crease line) to box back panel 24.
[0153] Although the connections of the lid outer front panel 31 and the lid back panel 36 to the lid outer and inner left and right side panels 34, 34, 35, 35 are shown as a plurality of parallel longitudinal crease lines, these connections could equally be made by single longitudinal crease lines. The remaining panel connections are single transverse crease lines.
[0154] To form the lid 3, the lid inner front panel is folded 180 with respect to the lid outer front panel 31 and are glued together. The lid gluing flaps 38 are glued to the lid top panel 37 to form the lid top wall. The lid left side wall is formed by gluing the lid inner left side panel 34 to the lid outer side panel 34. Finally, the lid inner right side panel 35 is glued to the lid outer right side panel 35.
[0155]
[0156] The blank 11 differs from the blank 10 shown in
[0157] Although not shown in
[0158] When forming the lid 3, both lid inner front panels are folded 180 with respect to the lid outer front panel 31 so that they contact, but only the lid outer front panel 31 and the second lid inner front panel 33 are glued together.
[0159] Preferably, an adhesive-free region is defined around the periphery of the first lid inner front panel 32 to prevent adhesive trickling into the first lid inner front panel 32. The average width of the adhesive-free region may be of at least 1 mm, for example of about 2 mm.
[0160]
[0161] The blank 12 shown in
[0162] The blank 13 shown in
[0163] When the lid 3 is formed, the first lid inner front panel 32 is folded 180 with respect to the lid outer front panel 31 so as to contact. As the second lid inner front panel 33 is connected to the first lid inner front panel 32, by folding the first lid inner front panel 32 with respect to the lid outer front panel 31, the second lid inner front panel 33 and the lid outer front panel 31 also contact. These latter panels are adhered together.
[0164] Preferably, an adhesive-free region is defined around the periphery of the first lid inner front panel 32 to prevent adhesive trickling into the first lid inner front panel 32. The average width of the adhesive-free region may be of at least 1 mm, for example of about 2 mm.
[0165] When the reclosable flap 8 is affixed to the first lid inner front panel 32 and the container 1 is opened for the first time, the opening force breaks the line of weakness 32 that connects the first and second lid inner front panels 32, 33, thereby mobilising the first lid inner front panel 32, which becomes rotatable about the crease line 32 that connects it to the lid outer front panel 31. The second lid inner front panel 33 remains attached to the lid outer front panel 31.
[0166]
[0167] The inner package blank 50 comprises an inner package front panel 51, inner package outer and inner left side panels 52, 52, inner package outer and inner right side panels 53, 53, an inner package back panel 54, an inner package bottom panel 55 and an inner package top panel 56. Although in

[0170]
[0171] The inner frame front panel 41 includes a rectangular cut-out 44 at the top free edge, in order to facilitate removal of the cigarettes from the box 2 when the inner frame is assembled from the blank 40. The rectangular cut-out 44 substantially corresponds to a front wall portion of the access opening 6 in the inner package 5. Accordingly, in the third embodiment of the invention, the cut-out is curved shaped to substantially match the curved shaped lower periphery of the access opening 6 in the inner package 5.
[0172] To form the inner frame, the inner frame left and right side panels 42, 43 are folded approximately 90 with respect to the inner frame front panel 41. In the assembled condition, the inner frame front panel 41 corresponds to the inner frame front wall, and the inner frame left and right side panels 42, 43 correspond, respectively, to the inner frame left and right side walls.
[0173]
[0174] Rollers 101 arranged below the serially progressing inner frames 4 draw the wrapping sheet 500 tautly over the front and back faces of the framed charge of cigarettes G and against opposite ends of the framed charge of cigarettes G, thereby wrapping the same to form inner package front, top, back and bottom walls. The rollers 101 then cooperate with a sealing head 102 to fuse or seal the drawn wrapping sheet 500 to form a transverse seam at the inner package back wall (not shown). A further elongate sealing head 103 (or pair thereof) following the rollers 101 then operate(s) to clamp and fuse a lateral seam (e.g. as a fin seal) in the barrier sheet 500 between each of the framed charge of cigarettes G to form the inner package left and right side walls. Trimmers 104 and rollers 105 may then trim and flatten the seams 13, 14 to complete the individual inner packages 5.
