Description

WO 2011/094481 PCT/US2011/022843 CARRIER AND BLANK THEREFOR FIELD OF THE INVENTION The invention relates to a carton or carrier for containing one or more articles such as bottles and two or more blanks for forming the same. More particularly, but not exclusively, the invention relates to a basket-style carrier of the top-loading type formed from two or more blanks, preferably shaped and configured to minimise wastage of the material from which the blanks are formed and preferably to enable use of mixed material in order to utilise thicker stronger material only where it is necessary and to use thinner weaker material in other parts thereby to reduce the overall material usage for cost and resource saving purposes. The invention also relates to a part formed carrier provided in a folded and glued, yet flat-form condition made from the blanks referred to above. BACKGROUND OF THE INVENTION In the field of packaging it is often required to provide consumers with a package comprising multiple primary product containers, such multi-packs are desirable for shipping and distribution and for display of promotional information. For cost and environmental considerations, such cartons or carriers need to be formed from as little material as possible and cause as little wastage in the materials from which they are formed as possible. Another consideration is the strength of the packaging and its suitability for holding and transporting large weights of articles. One such package is a basket-style carrier formed of foldable sheet material such as paperboard or the like. Such carriers are often used to package high-end goods, such as premium beers and lagers contained in bottles. The basket carriers are typically top loaded and advertise the premium product held within the carriers because the tops of the bottles are on show and visible to the consumers. The main panels of the basket carriers are, as far as possible, seamless and provide good printing surfaces for the quality display of graphics and other advertising and branding media. The carriers need to be strong to securely take the weight of say six bottles, and preferably WO 2011/094481 PCT/US2011/022843 -2 foldable into a flattish condition for transportation and storage. In addition, the material from which the carrier is formed is usually provided in large sheets or rolls and the blanks (in the form of tessellated nets) are struck or cut from these sheets of rolls. The typical outline shape or net of the blanks used to form the carriers are awkward to fit together and are often shapes that cause wastage of the sheets or rolls. This wastage is costly and undesirable. Furthermore, basket carriers are often provided with an internal partition structure for keeping the bottles contained therein separate in order to avoid clashing and damage of the articles. Though these partition structures perform a structural function they are not weight bearing aspects of the carrier. Therefore, utilising the high calliper strong board of high printing quality that is used for the weight bearing and outward facing display sections of the basket carrier is unnecessary for the partition structures. One such basket-style carrier is shown in EP1159200 in which an "in-line" blank is shown for forming a basket-style carrier having a crash-bottom. The side and end wall panels are adjoined one to the next in series which creates a main blank having a length that is nearly three times the length of a side wall of the overall carrier. These blanks nest or tessellate as shown in Figure 4C of EP '200. Separate blanks for forming partition structures that separate the internal volume of the formed basket carrier into separate cells to prevent the bottles banging against one another are also provided. A further example of a basket-style carrier is disclosed in US6131729, wherein a blank for forming the carrier is configured in a parallel-type relationship wherein one set of side and end panels is disposed opposite the other set of side and end panels. The side panels are separated by handle panels and the overall blank has a roughly rectangular outline save for the bottom panel (see 9 in Figure 23). The present invention seeks to provide an improvement in the field of basket carriers by providing a more economically producible package.

WO 2011/094481 PCT/US2011/022843 -3 SUMMARY OF INVENTION According to a first aspect of the present invention there is provided an arrangement of blanks for forming a basket style carrier, one of the blanks comprising panels for forming the sides, ends and a medial handle of the basket style carrier and the other of the pair of blanks comprising panels for forming a base of the basket style carrier. Preferably, the blanks comprise a series of main panels including: a pair of handle panels a pair of end panels, a pair of side panels, a bottom panel and a partitioning panel for forming a basket style carrier having opposed end walls, opposed side walls and a medial handle structure extending from which is a partitioning structure formed from the partitioning panel, wherein the arrangement of blanks comprises a first blank having the pair of handle panels, the pair of end panels and the pair of side panels and a second blank having the bottom panel and the partitioning panel. According to a second aspect of the invention there is provided a first blank for use in the formation of a top-loading basket style carrier, the first blank comprising two handle panels hinged together along a common edge by a medial hinge line which medial hinge line serves as a notional central axis of the first blank, each handle panel being disposed adjacent to but disconnected from first end panels and side panels, said first end panels each being hinged to a riser panel and each of the handle panels being connected to one of the riser panels such that each handle panel is indirectly coupled to a first end panel, the first blank further comprising two second end panels, one hinged to each of the side panels and each second end panel being hinged to a further riser panel, wherein the outermost edges of said side panels are cut edges being free of any direct hinge connection to any other panel of the first blank and thereby defining an edge of the first blank. Preferably, the first blank, when cut from a rectangular sheet of material results in less than 3% wastage of material about the perimeter of the blank. According to a third aspect, the invention provides a blank or blanks for forming a basket style carrier, the blank(s) comprising a series of main panels including: a pair WO 2011/094481 PCT/US2011/022843 -4 of handle panels, a pair of end panels, a pair of side panels a bottom panel, at least one handle reinforcing panel a partitioning panel and a riser panel, said main panels hingedly connected and arranged such that the blank is foldable and glueable to form a basket style carrier wherein the reinforcing panel, partitioning panel and riser panel are sandwiched between the handle panels, the blank(s) characterised in that a connection tab is hinged to one of the handle panels of the pair and is secureable at least about the riser panel and to the partitioning panel for securing the riser panel to the partitioning panel. According to a further aspect of the invention, there is provided a pair of blanks for forming a carton, the pair of blanks being superimposed during the construction of the carton, the pair of blanks comprising a positioning mechanism for facilitating alignment of the pair of blanks and for restricting relative rotational and/or relative longitudinal movement of the two blanks in the plane of the blanks, the positioning mechanism comprising two tabs struck from a first of the blanks and comprising two notches struck from the second of the blanks, each tab being hinged to the blank along a hinge line terminating in an angled shoulder portion and each notch having a shape matching the edge of the folded tab, the blanks being placeable with the second blank atop the first blank and the two tabs being foldable out of the plane of the first blank and into coplanar alignment with the second blank whereupon the shaped folded edge of each tab abuts the shaped edge of a notch of the second blank, said shoulder portions of each notch being oppositely angled relative to one another thereby to limit relative movement of the two blanks. Preferably, wherein the pair of blanks comprise a series of main panels including: a pair of handle panels, a pair of end panels, a pair of side panels, a pair of reinforcing handle panels, a bottom panel and a pair of inner handle panels for forming a basket style carrier having opposed end walls, opposed side walls and a medial handle structure, wherein the arrangement of blanks comprises a first blank having the pair of handle panels, the pair of end panels, the pair of side panels and the pair of reinforcing handle panels and a second blank having the bottom panel and the pair of inner handle panels, each inner handle panel of the pair comprising one of said WO 2011/094481 PCT/US2011/022843 -5 notches and each of the reinforcing handle panels being hinged to a handle panel to create said folded tabs. Optionally, the two handle panels are hinged together along a common edge by a medial hinge line which medial hinge line serves as a notional central axis of the first blank and wherein the shoulder portions are angled to notionally converge in the region of said notional central axis.

12 Detailed descriptions of specific embodiments of the package, blanks and cartons are disclosed herein. It will be understood that the disclosed embodiments are merely examples of the way in which certain aspects of the invention can be implemented and do not represent an exhaustive list of all of the ways the invention may be embodied. Indeed, it will be understood that the packages, blanks and cartons described herein may be embodied in various and alternative forms. The figures are not necessarily to scale and some features may be exaggerated or minimised to show details of particular components. Well-known components, materials or methods are not necessarily described in great detail in order to avoid obscuring the present disclosure. Any specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the invention. Referring to Figure 1, an outer shell blank 10 formed of foldable sheet material, in this example paperboard, is shown comprising on a left hand side thereof: a first side panel 20; first handle panel 28; reinforcing handle panel 36 and end panels 24a, 26a. The end panel 24a is hinged to the first side panel 20 along fold line 70 and the end panel 26a is hinged along the opposite end of first side panel 20 along fold line 74. In mirrored fashion, the right hand side of blank 10 comprises: a second side panel 22; second handle panel 30; reinforcing handle panel 38 and end panels 24b, 26b. The end panel 24b is hinged to the second side panel 22 along fold line 72 and the end panel 26b is hinged along the opposite end of second side panel 22 along fold line 76. The outer shell blank also comprises riser panels 44a, 44b, 46a, and 46b. The outer shell blank 10 is arranged such that the first and second side panels 20, 22 are disposed in close proximity adjacent one another and bounded by each other along a line of separation in the form of a cut-line 48 (cut-line 48 could take the form of a perforate or other frangible line such that the two side panels 20, 22 may need to be separated for constructing the basket-style carrier). The line of separation or cut-line WO 2011/094481 PCT/US2011/022843 - 13 48 between the two side panels 20, 22 will define a bottom edge of side walls of the carrier once the basket carrier has been constructed from the blank. Cut-line or line of separation (or frangible connection) 48 extends between end panels 24a, 24b of the left and right hand sides of the blank 10 and also between end panels 26a, 26b of the left and right hand sides of the blank. The end panels 24a, 24b and 26a, 26b are disposed end-to end in blank form, but are connected by the riser panels 44a, 44b and 46a, 46b so that upon construction of the blank 10 into a basket carrier, the pairs of end panels 24a, 24b and 26a, 26b will be joined and connected together to form composite end walls of the basket style carton. Arranging the blank in this manner provides for a compact blank 10 construction that can be cut from larger sheet material with a minimum of wastage. In comparisons conducted against known basket style blanks it is suggested that the present arrangement of blanks can be cut from larger sheet material with a 20% gain in the material utilised (i.e. not wasted). First and second handle panels 28 and 30 are disposed in a medial location within the completed basket carrier and as such are preferably free of connection to the first and second side panels 20, 22 and end panels 24a, 24b, 26a, 26b in blank form. The upper edge 57a of end panel 24a is preferably a cut-line or score line that cleanly separates the end panel 24a from the adjacent first handle panel 28. Though the blank 10 could be formed with a frangible connection 57a between the upper edge of end panel 24a and first handle panel 28, once broken, the upper edge 57a of the end panel may be rough or scruffy. Therefore it is preferred to define the upper edge 57a by a clean sharp accurate cut. Similarly, the upper edges 57a, 57b of end panels 24b, 26a, 26b and the upper edges 56, 54 of the first and second side panels 20, 22 are preferably defined by clean cut-lines such that these upper edges of the finished basket carrier are well-defined, distinct and not rough and therefore are aesthetically pleasing. Riser panels 44a, 44b are hinged to or foldably connected to the first and second handle panels 28, 30 along fold lines 62, 64 (which also hinge or foldably connect WO 2011/094481 PCT/US2011/022843 - 14 those riser panels 44a, 44b to the end panels 24a, 24b). As such the riser panels 44a, 44b provide a connection between the first and second handle panels 28, 30 and the remaining main panels of the blank 10. Riser panels 46a, 46b are hinged to end panels 26a, 26b along fold lines 66 and 68. The riser panels 44a and 44b are connected by a fold line 50; likewise, riser panels 46a, 46b are connected via a fold line 52. Cut-line 48 terminates at each of its ends at fold lines 50 and 52. In blank form, some means of connection of the first and second handle panels 28, 30 to the remainder of the blank 10 at their ends opposite to riser panels 44a, 44b is preferred in order to maintain the blank 10 as a manageable work piece that can be manipulated easily for constructing the carton. One such means of connection is provided in the form of nick portions 60, 58 which are hinged or foldably connected at one of their ends to the first and second handle panels 28, 30 and connected at the other end by a very fine tapered portion to an upper corner edge of the first and second handle panels 20, 22 respectively. The fine tapered portion is broken after or during construction of the blank 10 into a basket carrier, but holds the connection between the handle panels 28, 30 and side panels 20, 22 sufficiently long enough to enable a sufficient amount of construction of the basket carrier to be completed that the handle panels 28, 30 are connected some other way to the remainder of the blank (for example by connection to the carton riser panels 46a, 46b) and therefore subsequent manipulation of the blank is not hindered by the blank 10 being floppy and difficult to manipulate. The blank 10 also comprises optional reinforcing handle panels 36, 38 which are hinged to the main first and second handle panels 28, 30 by means of a fold or crease line 80, 78 respectively. Otherwise the reinforcing panels 36, 38 are preferably not connected to the main panels of the blank 10. The reinforcing panels 36, 38 are in other embodiments of the invention omitted. In yet further envisaged embodiments reinforcing handle panels 36, 38 are provided, but are hinged to the upper edges of the first and second handle panels 28, 30 or indeed to any other suitable location of the blank 10 and not necessarily hinged along fold lines 80, 78 running along an end edge of the first and second handle panels 36, 38.

WO 2011/094481 PCT/US2011/022843 - 15 First and second handle panels 28, 30 and reinforcing handle panels 36, 38 comprise handle apertures 40 (as are well known in the art). In this illustrated arrangement optional handle flaps 32, 34 are provided in the first and second handle panels 28, 30 and hinged thereto along fold lines 82, 84. In other arrangements, handle cushioning flaps 32, 34 are not provided or only one flap is provided or more than two flaps are provided. The flaps may take various configurations when provided and may be dimensioned and sized differently to those shown. A partition insert blank 12 is shown in Figure 2A. In this illustrated arrangement, the partition insert blank 12 is made from the same material as outer shell blank 10 namely paperboard. In other embodiments, the partition insert blank 12 may be formed of a different material to the outer-shell blank 10 and both blanks may be formed of any foldable sheet materials such as paperboard, cardboard, plastics materials and the like. Partition insert blank 12 comprises bottom panels 86a, 86b which are hinged together along fold line 104; insert handle panels 102a, 102b; side panel reinforcements 88a, 88b and lateral partition structures 90a, 90b, 92a, 92b. The lateral partition structures 90a, 90b, 92a, 92b are attachable to one of the first or second side wall panels 20, 22 of the main basket carrier by means of lateral partition glue flaps 94a, 94b which are hinged to the blank 12 along fold lines 96a, 98a, 100a, 96b, 98b and 100b. The bottom panels 86a, 86b are each hinged or foldably connected to the side panel reinforcements 88a, 88b (along fold lines 106a, 106b) which are in turn connected via one of the lateral partition structure glue flaps 94a, 94b to the insert handle panels 102a, 102b. The insert handle panels 102a, 102b comprise handle apertures 40 and in other embodiments may comprise handle cushioning flaps. Alternatively in further embodiments of the invention, the insert handle panels 102a, 102b may not be sized similarly to the first and second handle panels 28, 30 and may stop short of fully reinforcing the first and second handle panels 28, 30. An alternative embodiment of partition insert blank 12a is illustrated WO 2011/094481 PCT/US2011/022843 - 16 in Figure 2B in which the side panel reinforcements 88a, 88b are connected to both of the lateral partition structure glue flaps 94a and 94b. The shape, size, number and specific configuration of lateral partition structures 90a, 90b, 92a, 92b and lateral partition glue flaps 94a, 94b may take many and various forms that cannot all be illustrated. The configurations will depend upon the number of cells it is required to divide the basket style carrier into; the size of the carrier and other design requirements. The provision of partition structures is in fact optional, though is preferred because basket style carriers are often used for bottles and the partition structures prevent clanging of the bottles against one another which can prevent damage of the bottles. Where no partition structures are required, the section of blank 12 between the side panel reinforcements 88a, 88b and insert handle panel 102a, 102b may comprise no glue flaps, folds or partition elements. In yet further embodiments, the second blank for forming the basket carrier in conjunction with the outer shell blank 10 of Figure 1 may simply comprise a bottom wall only and securing panels (see the blank 113 of Figure 11 which could be employed with outer-shell blank 10 of Figure 1 to form a basket style carrier having no partition structures). Turning now to the construction of a basket style carrier from the outer-shell blank 10 of Figure 1 and the insert partition structure 12 of Figure 2A it is envisaged that the carton can be formed by a series of sequential folding operations in a straight line machine so that the blank and part-formed blank are not required to be rotated or inverted to complete the construction of a basket carrier. The construction process including the folding sequence and positions of adhesive used is not limited to that described below and may be altered according to particular manufacturing requirements. The partition insert blank 12 is folded about fold line 104 to bring the bottom panels 86a, 86b together into flat face contact and to bring fold lines 106a, 106b together such that, in the plane of the main partition insert blank 12, side panel reinforcements 88a, 88b are immediately adjacent one another. The folded bottom WO 2011/094481 PCT/US2011/022843 - 17 panels 86a, 86b extend approximately normal to the plane of the side panel reinforcements 88a, 88b. The initial folded position of blank 12 is shown in Figure 3; the bottom panels 86a, 86b cannot be seen as they extend out of the plane of the back of the paper. The folded partition insert blank of Figure 3 is to be inserted into and attached to the outer-shell blank 10. In readiness for this attachment, adhesive may be applied to the outer-shell blank 10 in the regions G1, G2 and G3. As depicted in Figure 4A, adhesive, glue or other attachment means is applied in region G1 for securing the insert handle panels 102a, 102b to the first and second handle panels 28, 30 respectively. Adhesive, glue or other attachment means is applied in region G2 for attaching side panel reinforcements 88a, 88b to the inside faces of first and second side panels 20, 22 respectively; and adhesive, glue or other attachment means is applied in region G3 for attaching lateral partition structure glue flaps 94a, 94b to the first and second side panels 20, 22 respectively. The folded partition insert blank of Figure 3 is inserted into the outer-shell blank 10 by threading the flat faced and folded bottom panels 86a, 86b through a slot, slit, gap or separation defined by cut line 48. In some construction methods, the outer shell blank 10 may be folded about its notional centre line defined by cut-line 48 and fold lines 50, 52 to open the gap between first and second side panels 20, 22 wider to facilitate the insertion of the folded blank 12 between the first and second side panels 20, 22. Such folding of the outer-shell blank may not be necessary. If the material from which the blanks are made has a "good side" that should appear outermost in the finished product and a "bad-side" which should appear innermost, then Figure 4A should be considered as showing the "bad-side" facing out with adhesive being applied to that side. The partition insert blank 12 should be folded so that when folded together it is the "good sides" of the bottom panels 86a, 86b that are facing outer-most. As such it is the 'good-side" of the remainder of the partition insert blank 12 that is placed into flat face contact with the outer-shell blank 10. Once the folded bottom panels 86a, 86b are threaded through slot 48, the remainder of the partition insert blank 12 is placed into flat face contact, aligned with and WO 2011/094481 PCT/US2011/022843 - 18 secured to the outer-shell blank 10 such that the insert handle panels 102a, 102b are secured to the first and second handle panels 28, 30 respectively; side panel reinforcements 88a, 88b are secured to the inside faces of first and second side panels 20, 22 respectively; and such that lateral partition structure glue flaps 94a, 94b are secured to the first and second side panels 20, 22 respectively. Figure 4B shows a plan view of the folded partition insert blank 12 and outer-shell blank 10 having been combined. Figure 4c shows a perspective view from the top of the folded partition insert blank 12 and outer-shell blank 10 having been combined, wherein the position of the folded bottom panels 86a, 86b is shown in dotted outline. Further shown in Figure 4c is a nominal position for the application of adhesive G4. This adhesive or other securement means is used to attach each reinforcing handle panel 36, 38 to the adjacent insert handle panel 102a, 102b (and therefore indirectly to the first and second handle panels 30, 32). The reinforcing handle panel 36, 38 is folded about its fold line 80, 78 and brought into flat face contact with the ("bad-side") face of insert handle panel 102a, 102b. The resultant part-formed blank is shown in Figure 5. Further shown in Figure 5 is a nominal position for the placement of adhesive G5. The adhesive G5 or other securement or fixing means is used to attach riser panels 44a, 44b to the insert handle panels 102a, 102b respectively. The riser panels 44a, 44b will subsequently be used to join the end panels 24a, 24b to form a composite end wall and therefore at this stage glue region G5 should not extend beyond the insert handle panels 102a, 102b and the riser panels 44a, 44b should not be attached directly to an inside face of the end panels 24a, 24b. Glue region G5 is depicted as a series of roughly parallel lines which run in the same direction as previously shown glue lines so that turning of the blank in a machine is avoided and glue guns can operate on the blanks 10, 12 as they travel along conveyors of the machine and pass the glue guns. The riser panels 44a, 44b are folded about fold lines 62, 64 and secured to the insert handle panels 102a, 102b. This resultant part-formed blank is shown in Figure 6.

WO 2011/094481 PCT/US2011/022843 - 19 Further shown in Figure 6 is the nominal position for the placement of adhesive G6. The adhesive G6 or other securement or fixing means is used to attach an upper portion of each riser panel 46a, 46b to the insert handle panels 102a, 102b and to attach the nick portions 60, 58 to upper portions of end panels 26a, 26b respectively. The resultant part-formed blank is shown in Figure 7 in plan view. Further shown in Figure 7 is the nominal position for the placement of adhesive G7 which is used to secure the left-hand side of the blank to the right hand side of the blank. Specifically, glue regions G7 are positioned to secure reinforcing handle panel 36 to reinforcing handle panel 38: to secure the top of riser panel 44a, to the top of riser panel 44b: to secure the top of riser panel 46a to the top of riser panel 46b; to secure portions of the insert handle panels 102a, of the insert partition structure blank 10 that lie between the lateral partition structures 90a, 92a to portions of the insert handle panels 102b, of the insert partition structure blank 10 that lie between the lateral partition structures 90b, 92b. These secured portions form part of a medial partition structure, along with the composite handle panels 36/28/102a and 38/30/1 02b. The medial partition structure splits the basket carrier into two longitudinal sections. The final folding stage is completed by folding the right-hand side of the blank about fold lines 50 and 52. The completed, but flat-form glued blank is shown in Figure 8. To open the blank of Figure 8 into a carton, the bottom panels 86b, 86a are separated from one another and the end panels 26a, 26b are folded into co-planar relationship; the internal structure "pops" into place as a result of opening the carton such that a six-celled basket carrier is formed. It may be useful (when the carton is empty at least) to employ a hook-shaped portion at the bottom of riser panels 46a, 46b and locate it in a complementarily hook-shaped edge of the bottom panel 86a/86b. Referring now to Figures 9 through to 16, there is shown a second or alternative embodiment of the present invention. In this second illustrated embodiment, three blanks are provided to form a basket-style carrier. In the second illustrated WO 2011/094481 PCT/US2011/022843 - 20 embodiment, like numerals have, where possible, been used to denote like parts, albeit with the addition of the prefix "100" or "200" to indicate that these features belong to the second embodiment. The second embodiment shares many common features with the first embodiment and therefore only the differences from the embodiment illustrated in Figures 1 to 8 will be described in any greater detail. Three blanks 110, 112, 113 are provided in this arrangement. The separation of the blank structure into three distinct parts may present further material savings by offering further flexibility in the layout or tessellation of multiple blanks on a larger sheet of material from which the blanks are cut. Each of the blanks 110, 112, 113 has a roughly or substantially rectangular cut-line or in other words has a perimeter shape that minimises wastage of material by not having extensive or odd shaped projections or appendages that leave odd-shaped and useless off-cuts of material. Outer-shell blank 110 of the three piece version is substantially identical in its construction to the outer-shell blank 10 of this first embodiment and is not described further. The blank 110 is shown in Figure 9. Together partition insert structure blank 112 and bottom insert blank 113 comprise the same component panels as the partition insert blank 12 of the first embodiment, albeit, the bottom panels 186a, 186b are provided in a separate blank 113 (see Figure 11) which is additionally provided with bottom panel glue flaps 187a, 187b. The partition insert structure blank 112 is illustrated as having different shaped lateral partition structures 190a, 190b, 192a, 192b, lateral partition structure glue flaps 194a, 194b and lateral partition fold lines 196a, 196b, 198a, 198b, 200a, 200b, though in essence and performance the lateral partition structure of the second embodiment is similar to that of the first embodiment. Turning now to the construction of a basket style carrier 210 (see Figure 16) from the outer-shell blank 110 of Figure 9: the insert partition structure blank 112 of Figure 10 and the bottom insert structure blank 113 of Figure 11. It is envisaged that the basket carrier can be formed by a series of sequential folding operations in a straight line machine so that the blank and part-formed blank are not required to be rotated or inverted to complete the construction of a basket carrier. The construction process WO 2011/094481 PCT/US2011/022843 - 21 including the folding sequence and positions of adhesive used is very similar to that used for the construction of the blanks 10 and 12 of the first embodiment and therefore only differences will be described, it being understood in addition that the construction process is not limited to that described below and may be altered according to particular manufacturing requirements. Bottom insert structure blank 113 is folded about fold line 204 to bring together the bottom panels 186a, 186b. The folded structure is threaded through the gap defined by cut-line 148 in outer shell blank 110 and the bottom panel glue flaps 187a, 187b are used to secure the bottom insert structure blank 113 to the outer-shell blank 10 using adhesive applied in the adhesive region G8 either side of cut-line 148 as shown in Figure 12A. The resultant combination of outer-shell blank 110 and bottom insert structure 113 is shown in Figure 12B. Thereafter, adhesive is applied (as described before) to secure the partition insert structure 112 onto the outer-shell blank 110. The resultant part-formed blank is shown in Figure 13 where adhesive regions G5 are also depicted for securing the riser panels 144a, 144b to the side reinforcing panels/insert handle panels 188a, 188b. Figure 14 depicts the folding of the riser panels 144a, 144b and the attachment of the reinforcing handle panels 136, 138 to the side reinforcing panels/insert handle panels 188a, 188b using adhesive applied in the region G4. The resultant part formed structure is shown in Figure 15. Also shown in Figure 15 is the nominal position for the placement of adhesive G6. The adhesive G6 or other securement or fixing means is used to attach an upper portion of each riser panel 146a, 146b to the side reinforcing panels/insert handle panels 188a, 188b and to attach the nick portions 160, 158 to upper portions of end panels 126a, 126b respectively. The resultant part-formed blank is then further glued and folded in a similar fashion to the folding and securement of the blank of the first embodiment. The completed basket carrier is shown in Figure 16. Referring to Figures 17 and 18A, there is shown a third embodiment of the present invention. In Figure 17, an outer shell blank 310 formed of foldable sheet material, in WO 2011/094481 PCT/US2011/022843 - 22 this example paperboard, is shown comprising on a left hand side thereof: a first side panel 320; first handle panel 328; reinforcing handle panel 336 and end panels 324a, 326a. The end panel 324a is hinged to the first side panel 320 along fold line 370 and the end panel 326a is hinged along the opposite end of first side panel 320 along fold line 374. In mirrored fashion, the right hand side of blank 310 comprises: a second side panel 322; second handle panel 330; reinforcing handle panel 338 and end panels 324b, 326b. The end panel 324b is hinged to the second side panel 322 along fold line 372 and the end panel 326b is hinged along the opposite end of second side panel 322 along fold line 376. The outer shell blank 310 also comprises riser panels 344a, 344b, 346a, and 346b. The outer shell blank 310 is arranged such that the first and second side panels 320, 322 are separated by the first and second handle panels 328, 330 and their adjoining reinforcing handle panels 336 and 338. A medial fold line 347 hinges the first and second handle panels 328, 330 to one another. The reinforcing handle panels 336, 338 are each hinged together by means of fold line 349, but are otherwise free of direct connection with one another due to the provision of a recess 351. Recess 351 is optionally rectangular in shape and is provided to reduce the amount of material concentrated at the central region of the blank, which upon construction of the blank into a carrier becomes, in some regions, eight plies of material thick. As such, in this arrangement, the side panels 320, 322 do not share a common edge. Nevertheless, the blank 310 is substantially rectangular for optimising the tessellation of blanks 310 on a larger sized sheet from which blanks 310 are cut. The end panels 324a, 324b and 326a, 326b are each connected to a riser panel 344a; 344b; 346a and 346b respectively so that upon construction of the blank 10 into a basket carrier, the pairs of end panels 324a, 324b and 326a, 326b respectively, will be joined and connected together to form composite end walls 324a/324b and 326a/326b of the basket style carton, with the associated riser panels 344a, 344b, 346a and 346b becoming part of the central structure of the basket carrier. Arranging the blank in this manner provides for a compact blank 310 construction that can be cut from sheet material with a minimised wastage.

WO 2011/094481 PCT/US2011/022843 - 23 In comparison for example to the blank for forming a basket carrier shown in Figure 7 of US6131729 which has a perimeter wastage of about 19%, the blank 310 for forming a basket carrier of the presently described embodiment of the invention has a wastage of about 2%. In other words, a perimeter wastage of less than 3%. The perimeter wastage is measured using a notional perimeter rectangle drawn about the extremities of the blank and subtracting from the area of that notional rectangle the amount of material that is wasted once the perimeter of the blank has been cut therefrom. (This measurement excludes any wastage from handle flaps cut from well within the perimeter. This measurement includes only the wastage caused by having to cut around the bottom panels (9 and 12) and riser panels (64) in US6131729 compared to the wastage caused by only having to cut around the riser panels (346a, 346b) in the present invention. As such this measurement does not quantify the overall material needed to make the complete basket carrier, nor does it quantify the wastage that might only be made if the blanks of US6131729 are tessellated in anything other than a rectangular fashion. Nevertheless, this measurement does show that the compact, rectangular or squarish blank of the present invention is shaped and configured to minimise wastage and to that end provides a significant benefit compared to the prior art. First and second handle panels 328 and 330 are disposed in a medial location within the completed basket carrier 310 and as such are preferably free of connection to the first and second side panels 320, 322 and end panels 324a, 324b, 326a, 326b in blank form. The upper edge 357a of end panel 324a is preferably a cut-line or score line that cleanly separates the end panel 324a from the adjacent first handle panel 328. Though the blank 310 could be formed with a frangible connection 357a between the upper edge of end panel 324a and first handle panel 328, once broken, the upper edge 357a of the end panel may be rough or scruffy. Therefore it is preferred to define the upper edge 357a by a clean sharp accurate cut. Similarly, the upper edges 357a, 357b of end panels 234b, 326a, 326b and the upper edges 356, 354 of the first and second side panels 320, 322 are preferably defined by clean cut- WO 2011/094481 PCT/US2011/022843 - 24 lines such that these upper edges of the finished basket carrier are well-defined, distinct and not rough and therefore are aesthetically pleasing. Riser panels 344a, 344b are hinged to or foldably connected to the first and second handle panels 328, 330 along a portion of fold lines 362, 364 (which also hinge or foldably connect those riser panels 344a, 344b to the end panels 324a, 324b). As such the riser panels 344a, 344b provide a connection between the first and second handle panels 328, 330 and the remaining main panels of the blank 310. Riser panels 346a, 346b are hinged to end panels 326a, 326b along fold lines 366 and 368. The riser panels 344a and 344b are separated by a gap 350; in contrast, riser panels 346a, 346b are connected via a fold line 352. A notional central line between the left and right hand sides of the blanks runs from the gap 350, along medial fold line 347, though the recess 351, along fold line 349 and terminates at fold line 352. Optionally, the riser panels 346a, 346b may be provided with bottom panel engaging elements 391a, 391b. In this arrangement hook shaped end portions of the riser panels 346a, 346b are operable to catch or otherwise engage an edge of the bottom wall of the carrier once constructed to restrict the carrier from collapsing back into its flat form even when empty of articles. The blank 310 also comprises optional reinforcing handle panels 336, 338, hinged to the first and second handle panels 328, 330 along fold lines 380 and 378 respectively. The reinforcing handle panels 328, 330 are otherwise free of connection with the remainder of the blank 310 and are not connected to the adjacent riser panels 346a, 346b. The reinforcing panels 336, 338 are optional. In alternative embodiments of the invention, it may be advantageous to provide, in blank form, some means of connection of the first and second handle panels and reinforcing handle panels 328, 330, 336, 338 to the remainder of the blank 310 at their ends opposite to the riser panels 344a, 344b. This may be preferred in order to maintain the blank 310 as a manageable work piece that can be manipulated easily for constructing the carton. This is less of a concern where the handle panels 328, 330, 336, 338 are disposed in the middle of the blank 310. Nevertheless, one such means of connection could be provided in the form of nick portions which may be WO 2011/094481 PCT/US2011/022843 - 25 connected at one of their ends to the reinforcing handle panels 336, 338 and connected at their other ends by a very fine tapered portion to an upper corner edge of the end panels 326a, 326b respectively. The fine tapered portion when provided, is broken after or during construction of the blank 310 into a basket carrier, but holds the connection between the reinforcing handle panels 336, 338 and end panels 326a, 326b sufficiently long enough to enable the blank 310 to be manipulated and handle by a machine as a flat unitary piece and for the reinforcing handle panels 336, 338 to be securely connected to the remainder of the blank 310 (for example by being glued to the insert handle panels 402a, 402b) such that subsequent manipulation of the blank is not hindered or hampered by the reinforcing handle panels 336, 338 flopping out of co-planar alignment with the rest of the blank (which might otherwise render the blank 310 difficult to manipulate). First and second handle panels 328, 330 and reinforcing handle panels 336, 338 comprise handle apertures 340 (as are well known in the art). In this illustrated arrangement optional handle flaps 332, 334 are provided in the first and second handle panels 328, 330 and hinged thereto along fold lines 382, 384. In other arrangements, handle cushioning flaps 332, 334 are not provided or only one flap is provided or more than two flaps are provided. The flaps may take various configurations when provided and may be dimensioned and sized differently to those shown. A positioning structure is provided for ensuring correct positioning and alignment of the insert structure 312a/312b when it is secured to the outer shell blank 310. In this arrangement, the hinged connection between the reinforcing panels 336, 338 and adjacent first and second handle panels 328, 330 is shaped such that a notch is defined by fold line 380/378, a shoulder portion 383 and straight cut-line/fold line 381/395 when the reinforcing panels 328, 330 are folded about the connecting fold lines 380, 378 and disposed into superposition with the first and second handle panels 328, 330. This is described further below in the description of the construction of the carrier, with reference to the shaped notches 508a, 508b of the insert structure 312a/312b, which is described in detail below.

WO 2011/094481 PCT/US2011/022843 - 26 One or more optional connection tabs 393 are provided to lock together the insert partition structure and outer shell to limit the possibility of the insert sliding or moving relative to the outer shell once the carrier has been constructed. In the illustrated embodiment, a single connection tab 393 is shown hinged along fold line 395 to the second handle panel 330. The connection tab 393 is struck from material that otherwise would have been used to form the reinforcing handle panel 338. A similar connection tab could be provided hinged to the first handle panel 328. Various alternative mechanisms are envisaged for providing an additional locking connection between the constituent parts of the basket carrier and the size, orientation, shape, configuration, number and position of the illustrated connection tabs is not limiting. A partition insert blank 312 is shown in Figure 18A. In this illustrated arrangement, the partition insert blank 312 is made from a different, lower calliper material compared to the outer shell blank 310. The insert blank is made from a lower weight per square meter paperboard that may or may not be bleach finished and coated for printing on one side. The partition insert blank 312 may be made from other foldable sheet materials, card board, plastics, paper or composite material that may be of the same or a different calliper and of the same or a different quality as the outer blank 310. For example, the outer-shell blank 310 may be formed of coated kraft board while the insert blank 312 may be formed of recycled board having a lower calliper than the outer-shell blank 10. In other embodiments, the partition insert blank 312 may be formed of the same material as the outer-shell blank 310. However, both the blanks may be formed of any foldable sheet materials such as paperboard, cardboard, plastics materials and the like. Partition insert blank 312 comprises a glue flap 487 hinged along fold line 506 to a first bottom panel 386a. The bottom panel 386a is hinged along fold line 406a to a side panel reinforcement 388a. The side panel reinforcement 388a is coupled to an insert handle panel 402a by means of partition structure. Similarly, insert handle panel 402b is coupled via a second partition structure to side panel reinforcement 388b, which is in turn hinged along fold line 406b to a second bottom panel 386b.

WO 2011/094481 PCT/US2011/022843 - 27 The first and second partition structures or lateral partition structures 390a, 390b, 392a, 392b are attachable to one of the first or second side wall panels 320, 322 of the main basket carrier by means of lateral partition glue flaps 394a, 394b which are hinged to the blank 312 along fold lines 396a, 398a, 400a, 396b, 398b and 400b. The bottom panels 386a, 386b are each hinged or foldably connected to the side panel reinforcements 388a, 388b (along fold lines 406a, 406b) which are in turn connected via one of the lateral partition structure glue flaps 392a, 392b to the insert handle panels 402a, 402b. The insert handle panels 402a, 402b comprise handle apertures 340 and in other embodiments may comprise handle cushioning flaps. Alternatively in further embodiments of the invention, the insert handle panels 402a, 402b may not be sized similarly to the first and second handle panels 328, 330 and may stop short of fully reinforcing the first and second handle panels 328, 330. An alternative embodiment of partition insert blank 312a is illustrated in Figure 18B in which the side panel reinforcements 388a, 388b are additionally connected to the insert handle panels 406a, 406b by the lateral partition structure glue flaps 394a and 394b. Otherwise, the two alternative partition insert blanks 312, 312a are identical and the basket carrier and its construction are further described and illustrated with reference to only the first of these, the one shown in Figure 1 8A. The shape, size, number and specific configuration of lateral partition structures 390a, 390b, 392a, 392b and lateral partition glue flaps 394a, 394b may take many and various forms that cannot all be illustrated. The configurations will depend upon the number of cells it is required to divide the basket style carrier into: the size of the carrier and other design requirements. The provision of partition structures is in fact optional, though is preferred because basket style carriers are often used for bottles and the partition structures prevent clanging of the bottles against one another which can prevent damage of the bottles. Where no partition structures are required, the section of blank 312 between the side panel reinforcements 388a, 388b and insert handle panel 402a, 402b may comprise no glue flaps, folds or partition elements. In yet further embodiments, the second blank 312a for forming the basket carrier in WO 2011/094481 PCT/US2011/022843 - 28 conjunction with the outer shell blank 310 of Figure 17 may simply comprise a bottom wall only and securing panels. Turning now to the construction of a basket style carrier from the outer-shell blank 310 of Figure 17 and the insert partition structure 312a of Figure 18A, it is envisaged that the carton or carrier can be formed by a series of sequential folding operations in a straight line machine so that the blanks 310 and 312a and part-formed blank are not required to be rotated or inverted to complete the construction of a basket carrier. The construction process including the folding sequence and positions of adhesive used is not limited to that described below and may be altered according to particular manufacturing requirements. The partition insert blank 312a of Figure 18A is to be attached to the outer-shell blank 310. In readiness for this attachment, adhesive may be applied to the outer shell blank 310 in the regions G31, G32 and G33. As depicted in Figure 19, adhesive, glue or other attachment means is applied in region G31 for securing the insert handle panels 402a, 402b to the first and second handle panels 328, 330 respectively. Adhesive, glue or other attachment means is applied in region G32 for attaching side panel reinforcements 388a, 388b to the inside faces of first and second side panels 320, 322 respectively; and adhesive, glue or other attachment means is applied in region G33 for attaching lateral partition structure glue flaps 394a, 394b to the first and second side panels 320, 322 respectively. The partition insert blank 312a of Figure 18A is placed onto the inside surface (non-printed side) of the outer-shell blank 310, If the material from which the blanks are made has a "good side" that should appear outermost in the finished product and a "bad-side" which should appear innermost, then Figure 20 should be considered as showing the "bad-side" facing out with adhesive being applied to that side. The partition insert blank 312 placed such that it is the "bad-sides" of the bottom panels 386a, 386b that are facing outer-most. As such it is the "good-side" of the remainder of the partition insert blank 31 2a that is placed into flat face contact with the outer-shell blank 310. Once the partition insert blank 312a is placed into flat face contact, aligned with and secured to the outer-shell blank 310, the insert handle panels 402a, 402b are WO 2011/094481 PCT/US2011/022843 - 29 secured to the first and second handle panels 328, 330 respectively; side panel reinforcements 388a, 388b are secured to the inside faces of first and second side panels 320, 322 respectively; and such that lateral partition structure glue flaps 394a, 394b are secured to the first and second side panels 320, 322 respectively. Figure 20 shows a plan view of the partition insert blank 312a and outer-shell blank 310 having been combined. Further shown in Figure 20 is a nominal position for the application of adhesive G34. This adhesive or other securement means is used to attach each reinforcing handle panel 336, 338 to the adjacent insert handle panel 402a, 402b (and therefore indirectly to the first and second handle panels 330, 332). The reinforcing handle panel 336, 338 is folded about its fold line 380, 378 and its inside face is brought into flat face contact with the ("bad-side") face of insert handle panel 402a, 402b. The resultant part-formed blank is shown in Figure 21. It can be seen that the positioning structure engagement feature or second notch shaped recesses 508a, 508b of the partition structure insert blank 312a are sized and shaped to match the positioning structure engagement lock defined by the fold lines 380/378 and angled shoulder portions 383. Whereas the notch shaped recesses 508a, 508b and the positioning structure engagement lock are rhombic, other matching or mating shapes will serve to accomplish the same function and the specific design of positioning feature shown is not limiting. The purpose of the positioning structure engagement feature is to locate the partition insert structure blank 312a in the correct position on the outer shell blank 310 and to limit relative movement between the two in order to prevent misalignment of the two parts. Specifically, the notch arrangement prevents the insert blank 312a from moving toward the riser panels 346a, 346b and the presence of two mirrored notch arrangements prevents the rotation of the insert structure 312a in the plane of the outer shell 310 (i.e. rotation of bottom panel 38rb toward or away from the riser panel 346b is prevent because of abutment of the shaped notches 508a, 508b with the shoulders 383. The obliquely angled shoulders 383 (substantially angled to converge WO 2011/094481 PCT/US2011/022843 - 30 on the notional medial line) are provided as mirror images to prevent planar rotation of the insert blank 312a in both clockwise and counter-clockwise directions. Further shown in Figure 21 is a nominal position for the placement of adhesive G35. The adhesive G35 or other securement or fixing means is used to attach riser panels 344a, 344b to the insert handle panels 402a, 402b respectively. The riser panels 344a, 344b will subsequently be used to join the end panels 324a, 324b to form a composite end wall and therefore at this stage glue region G5 should not extend beyond the insert handle panels 402a, 402b and the riser panels 344a, 344b should not be attached directly to an inside face of the end panels 324a, 324b. Glue region G35 is depicted as a series of roughly parallel lines which run in the same direction as previously shown glue lines so that turning of the blank in a machine is avoided and glue guns can operate on the blanks 310, 312a as they travel along conveyors of the machine and pass the glue guns. Further shown in Figure 21 is the nominal position for the placement of adhesive G36. The adhesive G36 or other securement or fixing means is used to attach an upper portion of each riser panel 346a, 346b to the insert handle panels 402a, 402b. The riser panels 344a, 344b are folded about fold lines 362, 364 until the riser panels 344a and 344b are disposed in flat face contact with the end panels 324a, 324b and secured to the insert handle panels 402a, 402b. Similarly, the riser panels 346a, 346b are folded into face contacting relationship with the insert handle panels 402a, 402b for attachment thereto. This is achieved by folding the end panels 326a, 326b and riser panels 346a, 346b about fold lines 374 and 376. This resultant part-formed blank is shown in Figure 22. Further shown in Figure 22 is the nominal position for the placement of adhesive G37 which is used to secure the connection tab 393 to the riser panel 346b and inner handle panel 402b. The connection tab, once secured in place serves to lock the outer handle panel 330, insert handle panel 402b, reinforcing handle panel 338 WO 2011/094481 PCT/US2011/022843 - 31 and riser panel 346b together. The connection tab 393 is optional. The resultant part formed blank is shown in Figure 23. In the embodiment illustrated, the connection tab 393 comprises a second hinge line, disposed at about 90 relative to the hinge line 395 connecting it to the handle panel 330. This second hinge line is optional, but is required when the connection tab 393 is shaped, (in a rounded rhombic shape as illustrated) such that is has a trailing piece. During construction of the basket carrier, the trailing piece, which is separated by a cut line from the adjacent reinforcing panel 338, becomes disposed beneath the end panel 326b (see Figure 22). Then, as the connection tab 393 is folded about hinge line 395, the trailing piece is moved as well and is repositioned on top of the riser panel 346b (see Figure 23). The second hinge line assists in the repositioning of the connection tab 393, specifically of its trailing piece. Further shown in Figure 23 is the nominal position for the placement of adhesive G38. Glue G38 is placed on folded over glue flap 487 once it is disposed in overlapping relationship with the bottom panel 386a by folding about fold line 506. Adhesive G38 is provided for securing together the bottom panels 386a and 386b. Adhesive G39 is provided for securing the left-hand side of the blank to the right hand side of the blank. Specifically, glue regions G39 are positioned to secure reinforcing handle panel 336 to reinforcing handle panel 338; to secure the top of riser panel 344a, to the top of riser panel 344b: to secure the top of riser panel 346a to the top of riser panel 346b (and to connection tab 393). And finally, to secure portions of the insert handle panels 402a, of the insert partition structure blank 312a that lie between the lateral partition structures 390a, 392a to portions of the insert handle panels 402b, of the insert partition structure blank 312a that lie between the lateral partition structures 390b, 392b. These secured portions form part of a medial partition structure, along with the composite handle panels 336/328/402a and 338/330/402b. The medial partition structure splits the basket carrier into two longitudinal sections. The final folding stage is completed by folding the right-hand side of the blank about fold lines 50 and 52. The completed, but flat-formed glued blank 311 is shown in Figure 24.

WO 2011/094481 PCT/US2011/022843 - 32 To open the blank of Figure 24 into a carton, the bottom panels 386b, 386a are separated from one another and the end panels 326a, 326b are folded into co-planar relationship; the internal structure "pops" into place as a result of opening the carton such that a six-celled basket carrier is formed. It may be useful (when the carton is empty at least) to employ a hook-shaped portion 391a, 391b at the bottom of riser panels 346a, 346b and to locate it in a complementarily hook-shaped edge of the bottom panel 386a/386b. The opened assembled basket carrier 410 thereby formed is shown in Figure 25. It can be appreciated that various changes may be made within the scope of the present invention, for example, the size and shape of the panels and handle apertures may be adjusted to accommodate articles of differing size or shape. The positioning of the side-walls reduces the overall length of the blank required and enables the ratio of the length and width of the outer-shell blank to be compact. The use of compact blanks with perimeter shapes that promote effective and efficient nesting and tessellation of the blanks is to some degree at least achieved by the bottom panels for forming the bottom wall and/or the partition structure of the basket carrier not creating an odd-shaped projection of the blank which in some currently available blanks contributes to material being wasted. This benefit in the bottom panels not creating an odd-shaped projection is achieved by the bottom structure being provided by a separate blank, though in some embodiments of the invention, it is envisaged that a single blank may be used which still has the benefit of being more compact because of the position of the side walls. Whereas the variously described features have been described in the context of a basket style carrier formed of two parts and having a certain configuration in the blank form, it is envisaged that the connection tab (393) and/or positioning structure (508a/508b; 383) may be advantageously employed in other areas in the field of packaging and scope of protection for these features should not be limited to the context of the specific basket carrier illustrated herein.

WO 2011/094481 PCT/US2011/022843 - 33 It will be recognised that as used herein, directional references such as "top", "bottom", "front", "back", "end", "side", "inner", "outer", "upper" and "lower" do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another. Any reference to hinged connection should not be construed as necessarily referring to a single fold line only; indeed it is envisaged that hinged connection can be formed from one or more of the following, a short slit, a frangible line or a fold line without departing from the scope of the invention.
