Abstract
Description
[0001] The present invention relates to a container for consumer goods, and a method of forming a container for consumer goods.
[0002] Some cigarette containers comprise a rigid outer housing and a sealed inner package within which cigarettes are contained, such as described in WO 2008 / 142540. Those containers have a resealable extraction opening in the inner sealed package selectively covered by a cover flap. The cover flap is connected to a hinged lid so that opening and closing the lid simultaneously opens and closes the cover flap over the resealable extraction opening. The cover flap is fixed to the inner package using an adhesive which extends about the whole of the extraction opening so that the cover flap can be detached from the inner package and fixed back again. This can allow the cover flap to seal cigarettes within the inner package when the lid is closed.
[0003] With those conventional pack structures, it is challenging to select a bonding strength of the adhesive surfaces adequate for a high quality sealing throughout the life of the container and that allows opening the lid, especially when the container is opened for the first time. If too strong, first opening causes damage to the lid, especially at the hinge and side panels, and, if too weak, attachment of the cover flap to the inner package fails and could even rub off after a number of openings. Further, such a selection has to be done for each combination of cover flap and inner package material or texture.
[0004] Several solutions to this problem have been proposed based on a reduction of the effective adhesion area. These solutions are still found unsatisfactory for they are complex and still dependent on the adhering surfaces, thus, only partially addressing the problem.
[0005] Another problem identified in these containers is that, once some cigarettes are removed from the inner package, repositioning of the cover flap to the inner package is notoriously less precise, even causing reattachment problems.
[0006] To solve this problem there have been attempts to use either more complex, and therefore costly, materials, especially for the cover flap, or to rigidise the inner package, for example, by using stiff inner frames located under the sealed package and that surround the cigarettes almost entirely. These solutions are still unsatisfactory as they are more costly and increase manufacturing complexity.
[0007] Yet another problem is that loose tobacco crumbs can become affixed to the adhesive, which can be unpleasant for users and can diminish the effectiveness of the adhesive. A further problem is that, under certain atmospheric conditions, the sealing provided by known cover flaps can actually be detrimental to the preservation of tobacco in smoking articles. Still another problem connected to these containers is the difficulty to open them for the first time, especially when provided with a seal or stamp at the line of closure of the lid as proof that the container has not been tampered with.
[0008] Another known container is described in WO 2012 / 089812. In this arrangement a cover layer is provided with an embossed indicium on an inner surface of an adhesive label. The embossed indicium is visible when the cover layer is moved from the closed position to the open position. However, movement of the cover flap between the closed and open positions can cause distortion of the embossed indicium, which may create undesirable viewing effects.
[0009] EP 2366637 describes a rigid package with a rigid outer container, which houses the inner package, and has an open end, and a lid hinged to rotate between an open position and a closed position opening and closing the open end respectively; the grip tab being designed to project from the lid when the lid is in the closed position closing the open end.
[0010] EP 2455302 describes another cigarette package with a hinged lid.
[0011] Therefore, it is an object of the invention to provide an improved container for consumer goods with a reclosable flap. Another object of the invention is to provide a method of forming a container for consumer goods.
[0012] According to a first aspect of the invention there is provided a container for consumer goods as defined in claim 1.
[0013] This minimises the potential for any slack in the reclosable flap when the lid is in the open position. Advantageously this can assist movement of the hinged lid from the open position towards the closed position. In addition, it can improve the positioning of the reclosable flap against the inner package when the hinged lid is moved from the open position to the closed position. In particular, it can improve the positioning of the reclosable flap along the top wall of the inner package to ensure that an effective seal is created and to assist with the preservation of the consumer goods.
[0014] It has been found that the substantially flat portion of the reclosable flap contributes to ease access to the contents of the inner package.
[0015] According to the invention, the hinge line may be positioned at a top wall of the inner package at a distance from a top, back edge of the inner package that is the same or shorter than a length of the lid-attachment portion measured from a free end along the reclosable flap. According to the invention, the ratio between the length of the lid-attachment portion of the reclosable flap and the distance between the hinge line and the top, back edge of the inner package is comprised between 1 and 3. This provides an adequate amount of tension to assist movement of the reclosable flap from the open position towards the closed position while limiting the risk of damaging the inner package or the reclosable flap due to excessive tension in the open position.
[0016] Preferably, to further improve reclosable flap repositioning, the ratio between the length of the lid-attachment portion of the reclosable flap and the distance between the hinge line and the top, back edge of the inner package may be of at least 1.1, for example of at least 1.2, for example of at least 1.3, such as of at least 1.4.
[0017] Preferably, to further reduce the risk of damaging the inner package or the reclosable flap, the ratio between the length of the lid-attachment portion of the reclosable flap and the distance between the hinge line and the top, back edge of the inner package may be of no more than 2.5, for example of no more than 2.2, for example of no more than 2, such as of no more than 1.8.
[0018] According to another aspect of the invention there is provided a method of forming a container for consumer goods as defined in claim 10.
[0019] Reclosable flaps according to any aspect of the invention may be connected to the inner package so as to be movable relative to the inner package about a hinge line. In some embodiments, the reclosable flap may be attached to the outer surface of the inner package so that it covers the access opening in the inner package. In such case, the reclosable flap preferably extends beyond the periphery of the access opening.
[0020] In other embodiments, the reclosable flap is defined by a cut line or a line of weakness in the outer surface of the inner package that covers the access opening. In such case, an adhesive label may be adhered to the inner surface of the inner package in a portion where the reclosable flap overlies the adhesive label and the access opening may be provided in the adhesive label, for example, by a cut-out or a line of weakness, or a cut line, that defines a flap that covers the access opening.
[0021] The reclosable flaps of any aspect of the present invention may be formed of, for example, high density polyethylene (HOPE), low density polyethylene (LDPE), biaxially oriented polypropylene (BOPP), nylon, polystyrene, cellulosic films, such as cellophane ®< and cellulose acetate, polyvinylchloride (PVC), paper, polyethylene terephthalate (PET) and mixtures of the foregoing.
[0022] Preferably, the consumer goods are smoking articles. However, the container may be suitable for a variety of consumer goods, such as confectionary, dry foodstuff, or the like.
[0023] The container is preferably a rectangular parallelepiped comprising two wider walls spaced apart by two narrower walls with right-angled longitudinal and right-angled transverse edges. Alternatively, the container may comprise one or more rounded longitudinal edges, rounded transverse edges, bevelled longitudinal edges or bevelled transverse edges, or combinations thereof.
[0024] The container may be formed from any suitable materials including, but not limited to, cardboard, paperboard, plastic, metal, or combinations thereof. Preferably, the outer housing is formed from one or more folded laminar cardboard blanks and, preferably, the cardboard has a weight of between about 230 g / m 2< and about 350 g / m 2< . In some examples, the cardboard has a weight of at least 250 g / m 2< , for example of about 270 g / m 2< .
[0025] When the container has dimensions similar to those of a conventional smoking article container, the lid is hinged preferably at a distance of the top, back edge of the container of 12 mm or less, such as 10 mm or less, for example of about 8 mm.
[0026] Once filled, containers according to the invention may be shrink wrapped or otherwise over wrapped with a transparent polymeric film of, for example, high or low density polyethylene, polypropylene, oriented polypropylene, polyvinylidene chloride, cellulose film, or combinations thereof in a conventional manner. Where containers according to the invention are over wrapped, the over wrapper may include one or more tear tapes. In addition, the over wrapper may be printed with images, consumer information or other data.
[0027] As used herein, the terms "front", "back", "upper", "lower", "top", "bottom" and "side" refer to the relative positions of portions of containers according to the invention and components thereof when the container is in an upright position with the lid of the outer housing in the closed position and the hinge line at the back of the container.
[0028] The term "longitudinal" refers to a direction from bottom to top or vice versa. The term "transverse" refers to a direction perpendicular to the longitudinal direction. The term "length" is used throughout the specification to refer to the longitudinal extension of a panel of a blank or a wall of a container. The term "width" is used throughout the specification to refer to the transverse extension of a panel of a blank or a wall of a container.
[0029] The term "inner surface" is used throughout the specification to refer to the surface of a component of the assembled container that is facing towards the interior of the container, for example towards the consumer goods, when the container is in the closed position. The term "outer surface" is used throughout the specification to refer to the surface of a component of the container that is facing towards the exterior of the container.
[0030] The term "permanent adhesive" is used throughout the present specification to refer to a generally high tack adhesive capable of forming a reliable and secure connection between two substrates such that the two substrates do not become substantially separated during the normal and intended use of the container. In fact, separation of two substrates affixed to one another by means of a permanent adhesive would typically cause some undesirable damage (e.g. tearing) to one or both substrates involved or leave an undesirable residue.
[0031] The term "resealable adhesive" is used throughout the present specification to describe a generally low tack, removable adhesive capable of forming connection between two substrates such that the two substrates can be repeatedly separated and re-attached to one another.
[0032] The term "activatable" is used herein to describe an adhesive element that is supplied to the consumer in a non-tacky state, such that it is unable to stick to another component of the container. An activatable adhesive element requires some form of activation on the part of the consumer to be brought into a tacky state for application to another component.
[0033] The invention(s) will be further described, by way of example only, with reference to the accompanying drawings in which: Figure 1 shows a perspective view of a container in a first embodiment of the invention in a lid open position; Figure 2 shows a detail of the container of Figure 1; Figures 3A and 3B show the container of Figure 1 with the lid in an intermediate position where Figure 3A is a perspective view and Figure 3B is a front view; Figure 4 shows a perspective view of a container in a second embodiment of the invention in a lid open position; Figure 5 shows a plan view of a reclosable flap of the container in the second embodiment of the invention; Figure 6 is a side view of the container with a hinged lid in a first open position in the second embodiment of the invention; Figure 7 is a top view of the container shown in Figure 6; Figure 8 is a front view of the container shown in Figure 6; Figure 9 is a side view of the container shown in Figure 6 with the hinged lid in a second open position; Figure 10 shows a perspective view of a container in a third embodiment of the invention in a lid open position; Figure 11 shows a plan view of a reclosable flap of the container in the third embodiment of the invention; Figure 12 is a front view of an inner package of the container in the third embodiment of the invention; Figure 13 shows a plan view of an alternative reclosable flap of the container in the third embodiment; Figure 14 is a front view of an alternative inner package of the container in the third embodiment of the invention; Figures 15 to 18 show four different embodiments of a blank for forming an outer housing; Figures 19A and 19B show two different embodiments of a blank for forming an inner package; Figure 20 shows an embodiment of a blank for forming an inner frame; and Figure 21 shows a system for forming an inner package.
[0034] The hinge lid container 1 shown in Figure 1 comprises a box 2 and a lid 3 that is hinged to the box 2 along a hinge line. Figure 1 shows the container 1 with the lid 3 in an open position. A bundle of cigarettes, wrapped in an inner package 5, is housed in the box 2 of the container 1.
[0035] 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.
[0036] 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.
[0037] 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 negate 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 figure 19B).
[0038] An inner frame 4 (formed from a blank shown in Figure 20) is mounted within the inner package 5 of the container 1. The inner frame 4 comprises an inner frame front wall, an inner frame left side wall and an inner frame right side wall which are positioned proximate the inner surface of the inner package front wall, inner package left side wall and inner package right side wall, respectively. The inner frame 4 may be optionally connected, for example, glued, to the inner package 5. The inner frame front wall includes a rectangular cut-out at the top free edge, in order to facilitate removal of the cigarettes from the box 2. The rectangular cut-out substantially corresponds to a front wall portion of the access opening 6 in the inner package 5. The walls of the inner frame extend above the upper edges of the box 2.
[0039] A reclosable flap 8 is attached to the outer surface of the inner package 5 so that it covers the access opening 6 in the inner package 5. The reclosable flap 8 is affixed to the inner package 5 at the 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. In other words, the reclosable flap 8 is attached to the inner package 5 so that a portion of the reclosable flap 8 is movable relative to the inner package 5 during lid 3 movement, while another portion of the reclosable flap 8 is not movable during lid 3 movement. The reclosable flap 8 extends beyond the periphery 57 of the access opening and is also affixed to the inner package flap 58.
[0040] 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 substantially around the periphery 57 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.
[0041] The resealable adhesive may also be used to affix 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.
[0042] The permanent adhesive may be provided inside a frame of resealable adhesive within the periphery 57 of the access opening 6, as shown in Figure 5, where the permanent adhesive is provided in an area 17 within the periphery 57 of the access opening 6. The frame may have a minimum separation with the periphery 57 of the access opening 6 of about 1 to 5 mm, for example of about 2 to 3 mm. By providing a frame of resealable adhesive around the permanent adhesive area 17 inside the periphery 57 of the access opening 6, it is possible to mitigate the inner package flap 58 from peeling off the label 8 after a number of openings while absorbing label 8 positioning tolerances over the inner package flap 58 that could cause the label 8 to permanently adhere to the inner package 5 inside and outside the access opening 6, thus, preventing opening the inner package 5 without damaging it. Although only represented in this embodiment, the permanent adhesive area 17 may be optionally present in any embodiment having an inner package flap 58.
[0043] 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.
[0044] As shown in Figure 2, the lid front wall comprises a lid outer front panel 31 and two lid inner front panels 32, 33 connected to the lid outer front panel 31 by a crease line. A first lid inner front panel 32 is connected to the lid outer front panel 31 only by the crease line, which defines a rotation axis 32' about which the first lid inner front panel 32 may rotate relative to the lid outer front panel 31. The first lid inner front panel 32 is, thus, rotatable about the lower front edge of the lid 3 relative to the lid outer front panel 31. A second lid inner front panel 33 is connected to the lid outer front panel 31 by the crease line and by permanent adhesive so that the lid outer front panel 31 and the second lid inner front panel 33 do not move relatively.
[0045] 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 provided in fluid state onto the label 8 and / or the inner surface of the lid 3 (e.g. spots of hot melt adhesive or PVA) or on a carrier material (e.g. a double-sided adhesive tape). 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. The inner surface of the free end 9 of the label 8 may be substantially free of resealable adhesive to reduce the force required to open the lid 3. Alternatively, the resealable adhesive applied to the inner surface of the label 8 may extend to its free end 9 to firmly close the lid 3.
[0046] 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 Figure 1. As the lid 3 is moved from the closed position, an edge 32" of the first lid inner front panel 32 is brought into pivotal contact with the outer surface of the inner package 5. This causes the first lid inner front panel 32 to pivot about the edge 32" from an initial position in which the first lid inner front panel 32 is substantially parallel to the lid outer front panel 31 to a position in which the first lid inner front panel 32 is approximately perpendicular to the lid outer front panel 31, as can be appreciated in Figure 3A. In other embodiments, not shown, the first lid inner front panel 32 pivots about the edge 32" from the initial position to a position in which the first lid inner front panel 32 is substantially perpendicular to the inner package 5. Further rotation of the hinge lid 3 peels off the label 8 from the inner package 5, thereby uncovering the access opening 6 in the inner package 5 through which one or more cigarettes can be removed.
[0047] Therefore, the container 1 of the present invention 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.
[0048] 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 Figure 3A. Further rotation of the hinge lid 3 causes the first lid inner front panel 32 to pivot about the edge 32" from an initial position in which the first lid inner front panel 32 is approximately perpendicular to the lid outer front panel 31 to a position in which the first lid inner front panel 32 is substantially parallel to the lid outer front panel 31, thereby closing the container 1. In other embodiments, not shown, the first lid inner front panel 32 pivots about the edge 32" from an initial position in which the first lid inner front panel 32 is substantially perpendicular to the inner package 5 to a position in which the first lid inner front panel 32 is substantially parallel to the lid outer front panel 31, thereby closing the container 1.
[0049] Therefore, the container 1 of the present invention 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.
[0050] The lid 3 is therefore movable about the box 2 between open and closed positions through an intermediate, stable position shown in Figure 3A. Movement of the lid 3 between the closed position and the intermediate position, or vice versa, requires overcoming a biasing force, which may be generated by cooperation of the reclosable flap 8 and a movable lid panel, the first lid inner front panel 32 in this embodiment.
[0051] The reclosable flap 8 is provided with indicia 118 on its inner side, which is the side that contacts the inner package 5 when the lid 3 is in the closed position. Indicia 118 may be provided at multiple locations on the reclosable flap 8. But, in particular, indicia 118 are provided toward the free end 9 of the reclosable flap where it is attached to the first lid inner front panel 32. The first lid inner front panel 32 is substantially flat and planar. The reclosable flap 8 is also flat and coplanar with the first lid inner front panel 32 where the two substrates are adjacent to one another. Thus, the indicia 118 on the reclosable flap 8 can be provided on a substantially planar surface in the vicinity of the first lid inner front panel 32. This has been found desirable because it minimises any possible distortion to the indicia 118 that could otherwise be introduced by a curved or non-planar surface.
[0052] In this example the indicia 118 is text. However, any other type or combination of indication or marking could be provided including numerals, logos and images. Advantageously the indicia 118 are presented on the reclosable flap 8 without any distortion in the vicinity of the first lid inner front panel 32.
[0053] Indicia 118 can also be provided on other parts of the reclosable flap 8 which are free to bend. Indicia 118 on bendable portions of the reclosable flap 8 are selected such that they can be viewed effectively even when distorted on a bendable substrate. A repeating pattern is an example of indicia 118 that might be provided effectively on a flexible substrate.
[0054] The indicia 118 can be provided by one or more of an ink, a varnish, a lacquer, embossing, debossing, and hot foil stamping. Where the indicia 118 are provided by an ink they can be separated from the consumer goods in the inner package 5 in order to prevent any potential migration of compounds to the consumer goods. This may be achieved by providing the indicia 118 at a position on the reclosable flap 8 that is offset from the access opening 6 when the hinged lid 3 is in the closed position. Alternatively, or in addition, a coating (not shown) may be provided on the reclosable flap 8 in the vicinity of the indicia 118 to prevent egression of compounds therefrom and into the consumer goods. In one arrangement a frame (not shown) can be provided on the reclosable flap 8 around the portion of the reclosable flap 8 that overlies the access opening 6 when the hinged lid 3 is in the closed position.
[0055] Advantageously the indicia 118 are visible at all times when the hinged lid 3 is moved from the closed position to the open position. In the first opening stage, the free end 9 of the reclosable flap 8 is pivoted about the inner package 5. The indicia 118 are visible at the intermediate, stable position shown in Figure 3A and Figure 3B when the container is in various orientations. In just two examples, the indicia 118 are visible in the perspective view shown in Figure 3A and in the front view shown in Figure 3B. In the second stage, the reclosable flap 8 is peeled away from the inner package 5, thereby uncovering the access opening 6 in the inner package 5. The indicia 118 that lies adjacent the first lid inner front panel 32 are visible during the first and second opening stages in a planar configuration that avoids any distortion from being introduced.
[0056] Figure 4 is a perspective view of another embodiment of a hinged lid container 1. For the sake of brevity, only differences between the containers will be explained below and the same numbering used for the container 1 of the first embodiment will be used to refer to similar elements.
[0057] 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 to the reclosable flap 8 and a second portion 16 which is substantially free of adhesive. 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.
[0058] 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. 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 Figure 4, the resealable adhesive extends about the left and side edges of the periphery 57 of the access opening 6 in the top wall of the inner package 5, about a portion of the left and side edges of the periphery 57 of the access opening 6 in the front wall of the inner package 5, but does not extend about the lower periphery 57 of the access opening 6.
[0059] 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 panel 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 panel 32 and the inner package 5 when the two are brought into pivotal contact.
[0060] 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.
[0061] 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.
[0062] Figure 5 is a plan view of the inner surface of the reclosable flap 8 used in the container 1 represented in Figure 4. The periphery 57 of the access opening 6 has been represented for ease of reference but is not a part of the reclosable flap 8. The hinge line 7 is also represented in dotted line. Similarly, transverse dotted lines represent the relative position of the upper, front and upper, back edges of the inner package 5 when the reclosable flap 8 is over the inner package 5 in the closed position.
[0063] As can be seen in Figure 5, the reclosable flap 8 includes a back surface 81, a top surface 82 and a front surface 83 when the lid 3 is in the closed position. These are the positions of the relevant surfaces 81, 82, 83 of the reclosable flap 8 on the rectangular cuboid which is the inner package 5.
[0064] 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 towards the closed position.
[0065] 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.
[0066] 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.
[0067] In this arrangement, the movable portion of the reclosable flap 8 includes the front surface 83 and a substantial portion of the top surface 82, while the non-movable portion includes the back surface 81 and a portion of the top surface 82 proximate the back, upper edge
[0068] The hinge line 7 is provided at a distance of around 7.5 mm from the top, back edge of the inner package 5. The top wall of the inner package 5 has a length of around 21.5 mm, and therefore the hinge line 7 is provided at a distance that is around 30% of the distance from the top, back edge of the inner package 5 to the top, front edge of the inner package 5. Where the inner package 5 accommodates cigarettes the position of the hinge line 7 roughly corresponds to the interface between a rear row and a middle row of cigarettes; this is best appreciated with reference to Figure 7.
[0069] Figure 6 is a side view of the outer housing 1 formed by the blank 13 shown in Figure 18 together with the reclosable flap 8 shown in Figure 5. Figure 7 is a top view of the same outer housing 1, and Figure 8 is a front view. The hinged lid 3 is shown in this configuration in a first open position. In the first open position the hinged lid 3 is rotated through substantially 180° from the closed position so that a lid back wall 36 is substantially parallel with and adjacent to a box back wall 24, although the two are not in contact. In this first open position the lid top wall 37 is arranged substantially perpendicularly to the box back wall 24.
[0070] Figure 9 is another side view of the outer housing formed by the blank 13, showing the hinged lid 3 in a second open position. In the second open position the lid back wall 36 is arranged in contact with the box back wall 24. Thus, an acute angle is formed between the lid top wall 37 and the box back wall 24. The second open position corresponds to a "fully open" position of the hinged lid 3, which is at an extreme end of the normal operating movement of the lid 3.
[0071] A ratio can be defined between a first distance measured when the hinged lid 3 is in the first or second open position along a straight line between a lower front edge of the lid front wall, which in this embodiment corresponds to the rotation axis 32' of the first lid inner front panel 32, and the hinge line 7 and a second distance along the reclosable flap 8 between the hinge line 7 and an edge of the reclosable flap 8 at the free end 9. The dimensions of the reclosable flap 8 and the blank 13 are selected so that the ratio between the first distance and the second distance is comprised between 70% and 100%. The second distance is a partly curved path along the reclosable flap 8. By contrast, the first distance is a straight line between the hinge line 7 and the rotation axis 32' of the first lid inner front panel 32 to which the reclosable flap 8 is attached. The position of the hinge line 7 can be seen most clearly with reference to Figure 7, which also shows the flap 58 in the inner package 5. This arrangement places the reclosable flap 8 in tension in both the first open position and the second open position. The tension in the reclosable flap 8 is higher in the second open position, as can be observed by the flatter shape that it adopts. The provision of tension in the reclosable flap 8 in the first and second open positions is advantageous because it biases the hinged lid 3 away from the first or second open positions and towards the closed position. This can improve the positioning of the reclosable flap 8 during the closing operation, especially against the top surface of the inner package 5.
[0072] In both the first and second open positions the reclosable flap 8 includes a flat portion and a curved or convex portion. In some configurations a concave curved portion may also be provided in the reclosable flap 8.
[0073] By a comparison between Figures 6 and 9, it will be appreciated that an angle between the first lid inner front panel 32 and the lid outer front panel 31 is changed when the lid 3 is moved from the first open position to the second open position. In the first open position the angle between the first lid inner front panel 32 and the lid outer front panel 31 is approximately 90°. In the second open position an acute angle that is less than 90° is formed between the first lid inner front panel 32 and the lid outer front panel 31.
[0074] In both the first and second open positions a portion of the reclosable flap 8 is held in a substantially flat, tensioned configuration between the hinge line 7 and the first lid inner front panel 32. In the first open position the length of the flat portion of the reclosable flap 8 is approximately 14 mm, which includes the portion where the reclosable flap 8 is attached to the (flat) first lid inner front panel 32. In the second open position the length of the flat portion of the reclosable flap 8 is approximately 37 or 38 mm, measured from the free end 9 of the reclosable flap 8. This also includes the portion where the reclosable flap 8 is attached to the first lid inner front panel 32. Thus, the length of the flat portion of the reclosable flap 8 is increased when the lid 3 is moved from the first open position to the second open position by a factor or a ratio which is approximately 2.7.
[0075] Figure 10 is a perspective view of a container 1 in a third embodiment of the invention, and Figure 11 is a plan view of the reclosable flap 8. Figure 12 is a front view of an inner package 5 for use in the container 1 of the present invention with the reclosable flap 8 of Figure 11. This embodiment differs from the second embodiment in that the second portion 16 of the reclosable flap 8 has approximately the same size and shape as the first lid inner front panel 32. In this arrangement the second portion 16 of the reclosable flap 8 does not extend as far as the access opening 6 when the hinged lid 3 is in the closed position. Thus, in this embodiment the resealable adhesive extends about the entire periphery 57 of the access opening 6.
[0076] Figure 13 shows a plan view of an alternative reclosable flap 8 for use in a container 1 of the present invention, and Figure 14 shows a front view of an inner package 5 with the reclosable flap 8 of Figure 13. The reclosable flap 8 is provided with a first portion 14 having a resealable adhesive, and a second portion 16 which is substantially free of resealable adhesive, and which is adjacent the hinge line 7. The reclosable flap 8 also includes a third portion 18 substantially free of adhesive which is adjacent the hinged lid 3, specifically at the connecting portion (free end 9) of the label 8. As can be appreciated in Figure 13, the third portion 18 does not include a portion of the periphery 57 of the access opening 6. Therefore, 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.
[0077] 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.
[0078] In this embodiment the first portion 14 of the reclosable flap 8 has a length l 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 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.
[0079] In another embodiment, not shown, the first portion 14 of the reclosable flap 8 has a length l 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 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.
[0080] 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 represented in Figure 5. As a result, the resealable adhesive extends 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, and about a portion of the left and side edges of the periphery 57 of the access opening 6 in the front wall of the inner package 5. The resealable adhesive does not extend about the lower periphery 57 of the access opening 6.
[0081] 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.
[0082] Figure 15 shows a blank 10 for forming the outer housing 1 represented in Figures 1 to 4 and Figure 10. The blank 10 is divided into two blank portions, a box portion 20 and a lid portion 30. Each blank portion comprises a plurality of panels in which each individual panel is connected to at least another panel, for example, by a crease or fold line.
[0083] 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 Figure 15 the connections of the box front panel 21 and the box back panel 24 to the box outer and inner left and right side panels 23', 23", 24', 24" 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.
[0084] 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.
[0085] The lid portion 30 comprises a lid outer front panel 31, two lid inner front panels 32, 33, 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.
[0086] Although in Figure 15 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.
[0087] In this embodiment, both the first and second lid inner front panels 32, 33 are connected to the lid outer front panel 31 as the first lid inner front panel 32 is surrounded by the second lid inner front panel 33. Although not shown in Figure 4, the first and second lid inner front panels 32, 33 may be connected by one or more breakable connections. These one or more breakable connections may be provided along at least one of the edges of the first lid inner front panel 32 that are not connected to the lid outer front panel 31, preferably, at least along an edge 32", which is opposite the edge 32' of the first lid inner front panel 32 that is connected to the lid outer front panel 31.
[0088] To form 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. 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'.
[0089] 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.
[0090] Figures 16 to 18 show alternative blanks 11, 12, 13 for forming an outer housing 1 similar to the one represented in Figures 1 to 4 and Figure 10. For the sake of brevity, only differences between the blanks will be explained below and the same numbering used for the blank 10 of the first embodiment will be used to refer to similar elements.
[0091] The blank 11 of the second embodiment shown in Figure 16 differs from the blank 10 of the first embodiment in that the lid portion 30 has only one lid inner front panel 32. When the lid 3 is formed, the lid inner front panel 32 is folded 180° with respect to the lid outer front panel 31 so that they contact, but no glue is applied to adhere those two panels.
[0092] The blank 12 of the third embodiment shown in Figure 17 differs from the blank 10 of the first embodiment in that the first lid inner front panel 32 is connected at one edge 32' to the lid outer front panel 30 by a crease or fold line and to the second lid inner front panel 33 at another, opposite edge 32" by a line of weakness, such as a row of perforations. The line of weakness 32" may be formed during a step of forming the outer housing 1, preferably before any panels of the blank 12 are folded, for example with a rotary scoring tool.
[0093] 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. 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 in contact. These latter panels are adhered together.
[0094] 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.
[0095] 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.
[0096] The blank 13 of the fourth embodiment shown in Figure 18 differs from the blank 11 shown in Figure 16 in the size and shape of the first lid inner front panel 32.
[0097] When the lid 3 is formed, the lid outer front panel 31 is moved towards the reclosable flap 8 so that the first lid inner front panel 32 comes into contact with an outer surface of the reclosable flap 8. As the first lid inner front panel 32 in blank 11 is neither glued to the lid outer front panel 31 nor connected to another lid panel by one or more breakable connections, the first lid inner front panel 32 rotates and there is a risk that it does so into an undesirable configuration. In particular, there is a risk that the first lid inner front panel 32 has an angle of more than 90° from the lid outer front panel 31. Such an arrangement would be undesirable because it would prevent the first lid inner front panel 32 from bonding effectively with the reclosable flap 8. In addition, the first lid inner front panel 32 would be likely to sweep a liquid permanent adhesive off the free end 9 of the reclosable flap 8. This would reduce the likelihood of effective bonding, and may cause unintentional bonding between other surfaces. This can be prevented by dimensioning the first lid inner front panel 32 so that, prior to any attachment between the first lid inner front panel 32 and the reclosable flap 8, the first lid inner front panel 32 brushes against the top, front edge of the reclosable flap 8 when the hinged lid 3 is moved from the open position towards the closed position.
[0098] These undesirable effects are advantageously mitigated by the present arrangement of the blank 13, which is achieved in part by having a first lid inner front panel 32 with a length of around 10.5mm extending in a direction that is perpendicular to the crease line 32'.
[0099] It has been found that relative sizes of the first lid inner front panel 32, lid outer front panel 31 and lid back panel 36 contribute to mitigate the above undesirable effects. Blank 13 is sized and shaped to mitigate these undesirable effects. In particular, the lid outer front panel 31 of the blank 13 has a length of around 30 mm, and the lid back panel 36 has a length of around 8 mm. As a result, a ratio between the length of the first lid inner front panel 32 to the length of the lid outer front panel 31 is of 0.35, while a ratio between the length of the first lid inner front panel 32 to the length of the lid back panel 36 is of about 1.3. A ratio between a length of the first lid inner front panel 32 to a distance between a top, front edge 19 of the inner package 5 and a top, front edge 27 of the box 2 is at least 0.3, and preferably no more than 0.5.
[0100] Figures 19A and 19B show two alternative blanks for forming the inner package 5 represented in Figures 1 to 14. The inner package blanks 50 are made from a substantially rectangular sheet of wrapping material that is folded along the longitudinal and transverse dashed lines represented in Figures 19A and 19B.
[0101] 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 Figures 19A and 19B the separation of the inner package front panel 51 and the inner package back panel 54 from the inner package outer and inner left and right side panels 53', 53", 54', 54" is shown each as two parallel longitudinal fold lines, this separation could equally be made by a single longitudinal fold line.
[0102] The inner package blank 50 represented in Figure 19A includes a cut line 57 that defines a flap 58. A line of weakness may be provided instead of the cut line so that the flap 7 separates from the inner package 5 only upon first opening of the container 1.
[0103] To form an inner package 5 from any of the blanks 50 represented in Figures 19A and 19B, the inner package outer and inner left side panels 52', 52" are connected (e.g. by glue application or heat-sealing) to each other to form the inner package outer left wall. The inner package right wall is formed by connecting the inner package outer and inner right side panels 53', 53".
[0104] In the inner package blank 50 represented in Figure 19B, the cut line 57 defines a cut-out 59.
[0105] Figure 20 shows a blank 40 for forming the inner frame housed in the inner package 5 of Figures 1 to 14. The inner frame blank 40 comprises an inner frame front panel 41, an inner frame left side panel 42 and an inner frame right side panel 43. Although in Figure 20 the connections of the inner frame front panel 41 to the inner frame left and right side panels 42, 43 are shown as a plurality of parallel longitudinal crease lines, these connections could equally be made by single longitudinal crease lines.
[0106] 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.
[0107] 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.
[0108] Figure 21 shows a system or apparatus 100 for forming an inner package 5 housing smoking articles, such as cigarettes or the like.
[0109] A series of inner frames 4, each of which is respectively combined with a charge of cigarettes, is transported in direction of arrow A along a packaging path by apparatus 100. The framed charged cigarettes G are conveyed under a continuous sheet of wrapping material 500 (e.g. a metallised plastics laminate film) which is fed from a supply roll (not shown). The wrapping sheet 500 has pre-formed reclosable flaps 8 for alignment with the respective access apertures 44 in the inner frame front panel 41 of each inner frame 4 transported under the wrapping sheet 500.
[0110] 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.
[0111] A set of blanks for forming the outer housing 1 according to any of the embodiments represented in Figures 15 to 18 are folded and glued about the inner package 5 to form the box 2 and lid 3, as previously explained. A permanent adhesive is applied on the outer surface of the reclosable flap 8, particularly at its free edge 9, to connect the reclosable flap 8 to the first lid inner front panel 32. As a result, a container for consumer goods according to the invention is formed.
[0112] To pre-form the reclosable flaps 8 in the wrapping sheet 500, the access opening 6 is first cut into the wrapping sheet 500 to define a flap 58 (Figure 19A) or a cut-out 59 (Figure 19B) and next the reclosable flap 8 is positioned on the wrapping sheet 500 over the access opening 6. The reclosable flap 8 is positioned to cover the access opening 6.
[0113] In some embodiments, application of the permanent adhesive on the outer surface of the reclosable flap 8 may be carried out during formation of the outer housing about the inner package 5, preferably during a step of folding and gluing the lid portion 30 of the blank.
[0114] In other embodiments, application of the permanent adhesive is done after the outer housing is completely formed around the inner package 5. In this case, attachment of the reclosable flap 8 to the first lid inner front panel 32 requires the additional steps of creating a space or gap between the lid 3 and the inner package 5 to provide access to the free end 9 of the reclosable flap 8; and attaching the reclosable flap 8 to the first lid inner front panel 32 through or via the space or gap. The attaching step may comprise bringing the first lid inner front panel 32 and an outer surface of the reclosable flap 8 closely together, desirably into contact with one another, for example, by applying pressure to the lid 3.
[0115] For example, the hinged lid 3 may be moved relative to the box 2 from the closed position to an at least partially open position so as to create the space or gap between the hinged lid 3 and the inner package 5 through or via which the reclosable flap 8 and the first lid inner front panel 32 are attached to one another. A liquid permanent adhesive may then be provided through or via the space or gap at the free end 9 of the reclosable flap 8 and the hinged lid 3 may then be rotated back to the closed position.
[0116] Preferably, the hinged lid 3 is rotated relative to the box 2 through an angle of less than about 35°, for example of less than about 30°, for example of less than about 25°, or, for example, in a range of between about 8° and about 20°. By limiting the degree to which the hinged lid 3 is opened, the deleterious effects of the opening operation can be substantially avoided, while providing sufficient space to provide an effective attachment between the reclosable flap 8 and the first lid inner front panel 32.
