Name of Applicant: CARTER HOLT HARVEY LIMITED Actual Inventors: GREGORY THOMAS BLOMFIELD and ROBERT WILLIAM COE Address for service A J PARK, Level 11, 60 Marcus Clarke Street, Canberra ACT in Australia: 2601, Australia Invention Title: Indexable Containers The following statement is a full description of this invention, including the best method of performing it known to us.

COMS ID No: SBMI-01717683 Received by IP Australia: Time 09:58 Date 2005-10-12 12-OCT-2005 00:49 A J PARK 12-CT-00500:9 PJ PF~K64 9 3566990 P.07 -2- INDEXABLE cONTMINEBS The present invention relates to containers to be formed from a laminate which includes at least onae corrugated core layer.

Containers in the form of erectable trays, cases or the 1like from one or more piece blanks are known for use in the packaging of goods. Frequenitly such containers are formed from a single blank cut from a sheet of a laminate which includes at least one corrugated core layer which defines a flute run direction. An example of such a material is a paperboard laminate which includes outer (usually kraft) paper liners having interposed adhesively therebetween a corrugated medium also of paper. Such corragated medium can be of one or more contiguous layers.

Other -forms of such materials may include two separated corrugated layers (each of one or more sheets of paper). ror example a double cushion corrugated board is one having three substantially planar paper sheets, each adjacent pair of sheets having interposed therebetweeti a corrugated medium of one or more sheets of paper. Preferably such double cushion material has the flute run direction of each corrugated layer runnuig parallel.

Such corrugated board materials with a flute run direction have a stacking strength capability greater where the flutes run vertically as opposed to horizontally. Various forms of container have been evolved to take advantage of such directionality of the material.

Some make good use of the material in this respect such as our DEFORTMA product range (see New Zealand Patent Specification No. 270912) or the P84wm product form of lberoAmericana. Others may make less effective use of such directionality.

The present invention relates to an improved container of a kind where a blank of such a material is to be erected to a container form which is to have stack indexing capability. The present invention recognises an advantage to be derived from indexing one on top of another reliant on an underlying cut edge transverse to the flute run direction. It is to deriving that advantage that the present invention has as an object.

In our New Zealand Patent Specification No. 270912 we disclose a tray like product range erectable from a single piece blank which has given rise to the DEEOR T 1 Product range. The full content of that specification is here included by way of reference.

The present invention in one aspect is directed to tray or container fonns that are a variant of the aforementioned

DEFOR

TM product range or which are capable of being offered as a potential replacement therefor.

c, Persons skilled in the art will appreciate the various embodiments within the ambit 0 of the present invention.

preferred form of the present invention will now be described with reference to the accompanying drawings in which Figure 1 is one option for a blank in accordance with the present invention, Figure 2 shows an erected container of a kind having two indexing projections on t each indexing wall and a column like triangulated comer structure, C 10 Figure 3 shows by reference to a double cushion corrugated board material a f comer of a container as shown in Figure 2, the indexing projection in such a variant being 8a pop-up single type projection as depicted in Figure 2 (of course other forms of indexing projection above the transition being capable of being provided such as those that by doubling the projection back and re-attaching it in some way provide no exposure of the flutes at the top of the indexing projection).

Figure 4 is a plan view of a blank of another embodiment of the present invention, such an embodiment being an adaption of the DEFOR

T

M type container, and Figure 5 shows an alternative embodiment of the present invention.

Forms of the present invention will now be described as options of the present invention with reference to a double cushion paperboard. In the preferred form shown in the drawings the base 1 is rectangular and each longer side has two indexing projections on each indexing wall.

As can be seen from Figure 1 fold lines "I f' and "II II" separate the base 1 from each indexing wall flap sequence, with the first indexing wall flap 3 being hinged by the fold line "I I" from the longer side of the rectangular base 1 and with the more outwardly in the blank second indexing wall flap 4 hinged by a fold line "II II" from the flap 3.

As can be seen separating each of the flaps 3 and 4 are cuts 10 which leaves hinging regions 12 skirting on either side of the cuts 8 which provide the indexing pop-up projection 11. As can be seen more outwardly of each hinging region 12 is an exposed cut face provided by (in the preferred form) both of the flaps 3 and 4, ie; see 13, 14, 15 and 16.

It can bee seen that cutouts 9 are provided for indexing purposes at or adjacent or both the fold lines I I so as to index receive a projection 11 in each instance of a like container.

COMS ID No: SBMI-01717683 Received by IP Australia: Time 09:58 Date 2005-10-12 12-OCT-2005 00:52 A J PARK 12-CT-05 0:5 p PE~<64 9 3566990 P.14 -9- The non indexing wall flaps 2 are hinged on the broken line by a fold line 17 from.

o the base 1 and this up folded flap 2 is to have adhesively affixed thereto first the flap extensionl 5 of the first indexing wall flap 3 and thereon the part 6 of the flap extensionl of o the second indexing wall flap 4. The fold lines shown in the blank leave a trianguilating (preferably straighit) region 7 which tiangulates the corner to provide the column like fornm depicted in the figures.

Persons skilled in the art will appreciate that if desired the flap 5 could be adhesively affixed outwardly of the flap 2 and the flap extension 6 instead be glued directly on to the up folded non indexing wall flap 2 such as, for example, in the DEFOR"" case of Carter Holt Harvey Limited.

'4Th In the preferred form of the present invention the base 1 is preferably pre-crushied o in those regions that are to overlie an exposed flute cut edge 13, 14, 15 and 16 and preferably also 17 and IS. Indeed such pre-crushing prior to carton erection will assist in clearance for tho flaps during the assembly stage.

As can be seen the present invention enables a single level for the transversely cut material to be presented by regions 13, 14, 15, 16, 17 and 18 and such a level is at least at if not above the level (at least after any crushing) of the hinging regions 12.

As mentioned earlier the pop up type indexing projection which extends above the transition between the first and second indexing wall flaps in the erected container could alternatively be a different form such as that utilised by a number of companies where an even greater cat out has part thereof folded back and adhesively or otherwise reattached to some part of the indexing wall.

Perons also, skilled in the art will appreciate that scallops or the like 19 can be provided between the hinging regions 12 and the outwardly flanking cuts 10 that provide the support regions 13, 14, 15 and 16. Such scallops for convenience are not shown in Figure 1 other than in broken outline as they are optional.

In the embodiment as shown in Figure 4 there is a substantially rectangular base 19 having two wall flap sequences 20. There is an indexing wall flap 21 and an indexing wall flap 22 and cuts from one into the other to define a lug forming projection 23 which will hinge at 24 with the distal region 25 being down turned to adhere inwardly of the indexing wall (when formed) against the reverse side of the member 22 and/or the revealed face of the member 2 1.

Each member 21 and 22 has extensions 26 and 27 respectively. Extension 26 is adapted to lie outwardly of the non indexing wall flap 28 when it is erect whilst the COMS ID No: SBMI-01717683 Received bylP Australia: Time 09:58 Date 2005-10-12 12-OCT-2005 00:52 p 3 PPM< 64 9 3566990 12-OCT-2005 00:52 A J PARK 64 9 3566990 inextension 27 with its fold lines 29 is adapted to trunicate the interior (as in the DEOR' o cotainr) with the region 30 itself only being affixed inwardly to the member 28.

Equally within the scope of the present invention however are variants Of the o ~arrangemnent of Fiue1where both members 26 and 27 are affixed inwardly Of the non Cl 5 indexing wall flap 28 with the maember 26 directly adhered thereto and the portion 27 of the extension 30 affixed thereto so as still to provide a column like structure which truncates the corner 4 In the erected condition openings 31 accommodate the appropriate projections thus Cl fanned.

Cl 10 In the arrangement as shown the cross hatching shows regionsi Of Pre-crushing Of 0 the preferred corrugated board medium, eg; a paperboard liner, at least one corrugated core Cl to provide the flute run direction and a further liner. There can be multiple players of corrugated medium interposed if necessary by further sheets of appropriate material. In the preferred form of the present invention the flute run direction is in the strowed direction (likewise in Figure An aspect of the present invention is the full cuffing at regions 32 but the allowing of bridges 33 oin the transition zone to provide the hinging links. Obviously these transitions 33 need not be directly against each projection being formed and indeed can be spaced therefrom, ie; there can be cuts right to the projections from a remote bridging of the flaps.

An advantage of the arrangement however is that cut flute exposed edges of each of members 21 and 22 provide a region which without pre-crushing is ready to directly to bear weight in an indexed stacked condition.

Figure 5 shows an alternative where, just as an example, the indexing tugs are provided at the lesser ends and no provision is made for truncating of the corners. Persons skilled in the art will appreciate however the provision of the indexing tugs and corresponding openings on either the greater or lesser sides of the rectangular base does not dictate the form that must be used. Indeed, especially with the end indexing forms, even one projection only may suffice per indexing wall.

With the arrangement as shown in Figure 5 there is preferably still angling inwardly slightly as with the indexing wall flap sequence 20 of the embodiment of Figure 4, but not necessarily so. With the arrangement as shown in Figure 5 the extensions 34 and respectively are adapted to be affixed inwardly of the noni indexing wall flaps 36 and COMS ID No: SBMI-01717683 Received by IP Australia: Time 09:58 Date 2005-10-12 12-OCT-2005 00:52 p j 64 9 3566990 P.16 12-OCT-2005 00-52 A J PARK 64 9 356690 P-16 -inot to truncate the comer. Flap 35 affixes to flap 34 which is directly affixed to the non 0 o indexing wall flap 36 which, as shown, includes a lidding flap 37.

Any lidding flap is of course an optional feature of any variant of the present 0 invention.

In the arrangement as shown in Figure 5, the cut regions 38 which correspond to cut regions 32 of the embodiment of Figure 4 leaves bridging regions 39 which are the equivalent of the bridging regions 33.

0Persons skilled in the art will appreciate how such positioning could instead be c-i utilised with the embodiment of Figure 4. Again pre-crushing is shown as shaded and ci 10 preferably the indexing wall (this time the end wail) when erected is slightly inwardly 'fl inclined. Again the exposed flute cuts 38 provide for a direct load bearing on a preo crushed base region.

Persons skilled in the art will appreciate how the present invention offers alternatives to existing forms.

21. A container formed from a blank of a laminate having a corrugate flute run odirection, said container comprising or including: a rctagulr bse avig a opose par of longer sides and an opposed pair of o shorter sides, said base including a plurality of openings, a flap sequence ("indexing wall flap sequence") of two wall flaps ("indexing wall flaps") extending from each of thle sides of a pair of sides of said rectanguilar base, a first indexing 'wall flap of each indexing flap sequence being connected to the base by a fold line, and the second indexing wall flap of each indexing flap sequence being connected to In the first flap, and each indexing wall flap of each flap sequence having an extension flap beyond a fold-line extending normal or substantially normal to said fold-line of said first indexing wall flap with the base, and o a wall flap ("non-indexing wall flap") extending from each of the other sides of Cl said base, wherein said container, when erected, has each indexing wall flap sequence folded to define an upwardly directed (preferably slightly inwardly inclined) indexing Wall, and, in the erected form, above a transition between each sequence of the first indexing wall flaps and second indexing wall flaps there is or are defined by the indexing wall at least one projection, the or each projection being indexable by one of said plurality Of openings of the base of another erected container in a stacking configuration, and wherein, the blank has been formed such that each wall flap of each indexing wall flap sequence has, as the transition therebetween, at least one hinging axis above which some of the blank material projects from one wall flap, and wherein there is at least one hinging zone at the transition resulting from the non cutting fully of the blank material along the transition such that there is defined at the top of each indexing wall both at least one exposed flute end cut region for direct bearing under a like container in a stacking condition and (ii) at least one hinging link.

22. A container of claim 2 wherein the non cutting fully of the blank material is a mixture of flal cutting along certain parts of the transition to leave somne linkcing or bridging regions uncut (irrespective of whether or not, to assist the hinging function, there is any cutting normally to the transition to better render flexible for hinging purposes the linking or bridging region).
