SPECIFICATION

FOR A PETTY PATENT

ORIGINAL

Name of Applicant: Actual Inventor: Address for service in Australia: Invention Title: CARTER HOLT HARVEY LIMITED ROBERT WILLIAM COE A J PARK SON, Level 11, 60 Marcus Clarke Street, Canberra ACT 2601 Pack The following statement is a full description of this invention, including the best method of performing it known to me/us "A PACK" The present invention relates to article or produce carrying assemblies, components thereof and related methods of use thereof. Many forms of container are known for carrying produce. The present invention relates to a container of a kind capable of being erected from a blank of a planar material (eg corrugated board or a paper board) or from multiple blank pieces of such a material.

New Zealand patent specification 230735, the full content of which is hereby included, relates to an assembly of such a container in conjunction with a cover having side and end walls of a trapezium configuration whereby hand holds provided by flaps to be expressed from the plane of the blank from which the cover is formed allow an uplifting with hand holds of the covered container. The present invention relates to similar such structures but having an advantage there over.

The present invention relates to a pack of or for material(s) comprising or including; a container to carry the packed or the to be packed material(s), said container having at least a substantially rectangular base and upstanding gusset interconnected walls, (ii) a bottomless surround for the upstanding walls (optionally flap lidded at least in part), the surround to provide walls about the walls of the container, wherein said container is erected from a blank to provide, at a pair of opposed sides, an external downwardly directed hand grippable edge or foldline, each held in place with an engagement with the gussets, and wherein said surround has hand openings in the two corresponding opposed walls, which openings will or do register with said hand grippable edge or foldline to allow a synchronous uplift of both the container and the surround using said openings and the hand grippable edge or foldline.

Preferably each hand opening of the surround is provided by a die cut flap adapted to bear under the hand grippable edge or foldline of the container during any said synchronous uplift.

0o+' Preferably said container is a lidded container of a paperboard or paperboard -3including laminate and said surround is at least partially lidded.

A preferred form of the present invention will now be described with reference to the accompanying drawings in which; Figure 1 shows an isometric view of a preferred container in accordance with the present invention showing the feature A to enable uplifting of an end of the container, Figure 2 is an isometric view of one form of surround for association over the container of Figure 1, the surround having flap provided openings to enable into engagement of the flap under the feature A and to enable the uplifting of the surround and the container together, Figure 3 shows the surround of Figure 2 being lowered over the container of Figure 1, Figure 4 shows the arrangement after the lowering of Figure 3, the flaps of the surround being shown in an open condition for convenience (they can of course be adhesively fastened), and Figures 5 through 11 show in sequence the folding of the container, (Figure 5 showing the blank cutout of said container, Figure 6 showing the folding of the walls into an upstanding position, Figure 7 showing the web connections folded to provide the side wall panels of the container, and Figures 8-11 shows the flap extension of said of said container being folded under the web connections to provide said feature), and Figure 12 shows the blank cutout of said surround.

The preferred container is that shown in Figures 1 and 5 through 11. It is preferably formed from a blank of for example, a laminate of a waterproofing plastics material (optionally metallised) and an appropriate paperboard. The paperboard can be a dense card or a laminate of kraft paper and/or other paperboard materials, eg; a corrugated medium or the like.

The present invention envisages however an arrangement whereby a surround formed, for example, from a blank of an appropriate paperboard as shown in Figure 12, can be used to confer an addition to the peripheral wall strength of the assembled container (see Figure 4) whilst allowing the uplifting of the container in such a form.

!As can be seen from Figure 5 a preferred single piece blank comprises a base 1 -4which is preferably rectangular, wall panels 2, flanging walls or wall panels 3, closeable flaps 4 from the flanking walls 3, and outward extension 5 to be folded on a fold-line 6 to provide the downwardly directed feature shown in Figure 1 and to be held in position by the further extension 7 being tied upwardly under the flap The webs 8 and 9 in each instance are not broken from the wall panels 2 and 3.

The surround itself is preferably formed from the blank shown in Figure 12 (ie; adhered by flap 10. Die cut in panels 12 is a flap providing opening for each end. For convenience the flap is shown out of the plane in Figure 12. This flap 13 is adapted in the condition as shown in Figure 4 to underlie and engage the downwardly directed edge 6 so as to associate the two components together or at least assist in the uplifting of the weight carrying container under the cover of the surround which preferably is provided with the 4 closure flaps depicted in the drawings.

Persons skilled in the art will appreciate how the arrangement as described provides an advantage over the aligned hand hold arrangements of aforementioned New Zealand Patent Specification 230735. At the very least there is provided a better degree of water tightness for the inner container. This is particularly useful where, for example, fish or the like is being carried in what is to be preferably a waterproof crate or tray type environment optionally containing ice and preferably with multiple closures, eg; the flaps of the container itself preferably in turn overlaid by the cover.

The nature of the surround is such as to provide greater strength than would otherwise be the case with the choice of material in the construction of the crate or container component of the assembly.

Outward wall bulge is resisted by the surround and with the preferred use of, for example, a plastic web laminated on to the paperboard, the base of the container or crate is sufficiently strong to support any load carried therein, stacking strength being enhanced by the ability of the base to conform to an underlying assembly in a stack and of course the combined wall strength of both the container and the surround.

Claims

1. A pack of or for material(s) comprising or including; a container to carry the packed or the to be packed material(s), said container having at least a substantially rectangular base and upstanding gusset interconnected walls, (ii) a bottomless surround for the upstanding walls (optionally flap lidded at least in part), the surround to provide walls about the walls of the container, wherein said container is erected from a blank to provide, at a pair of opposed sides, an external downwardly directed hand grippable edge or foldline, each held in place with an engagement with the gussets, and wherein said surround has hand openings in the two corresponding opposed walls, which openings will or do register with said hand grippable edge or foldline to allow a synchronous uplift of both the container and the surround using said openings and the hand grippable edge or foldline.

2. A pack of claim 1 wherein each hand opening of the surround is provided by a die cut flap adapted to bear under the hand grippable edge or foldline of the container during any said synchronous uplift.

3. A pack of claim 1 or 2 wherein said container is a lidded container of a paperboard or paperboard including laminate and said surround is at least partially lidded. Dated this 10th day of August 1999 By the authorised agents 251111a Son (er: Agents for the Applicant Ii wo
