The present invention relates generally to containers made from a blank of foldable material for holding produce such as seafood, poultry and meat. However, it will be appreciated that the invention is not limited to this particular use.
Containers holding produce such as meat, poultry and seafood are often stacked on top of each other in order to maximise use of available floor space in, for example, a shop or truck. It can therefore be appreciated that these containers require a suitable compressive strength to withstand the loads that they may be subjected to.
Containers with integral support posts have superior compressive strength and are typically formed as stackable containers having corner post portions which are able to be received in apertures provided in similarly constructed containers when such containers are stacked on top of one another. However, one disadvantage is that the torsional strength of such containers is not significantly better than containers that do not have corner post portions.
Corner posts work best when one container is stacked directly on top of another. However, when there is a requirement for cross stacking (i.e. each layer or tray stacked at 90° to the one below it), the strength of the stack is reduced significantly because the corners no longer align. In such applications, a more even perimeter strength and container rigidity is desired.
21128356_1 (GHMatters) P107034.AU.1 5/09/24
Additionally, meat, poultry and seafood are often wet and/or exude fluid such as blood and water. Typically, a container holding such produce is put a plastic bag to contain any fluids that escape the container. However, there remains a risk that these fluids would contaminate the surrounding area if the bag is perforated. This is a particular concern for containers formed from foldable blanks because the container joints may not be suitably sealed. Leakage of fluid from the container may damage other containers that the leaked containers are stacked on top of. These fluids may also adversely affect the structural integrity of the container.
According to a first aspect of the present invention, there is provided a container made from a blank comprising: a base panel; a side wall extending about the base panel to form a receptacle, in which the side wall includes a plurality of sub-panels that are arranged relative to each other to form corners in the side wall between each adjacent sub panel; a ledge panel extending from the side wall to form a surface on which another alike container can be seated; a strut that supports the ledge panel and surface of the container, the strut formed by an extension panel that is inclined relative to the side wall; and a gusset panel interconnecting sub-panels at the corners so that at least part of the receptacle formed by the base panel, the side wall and the gusset panel is liquid tight.
In the operative position, the ledge panel forms a ledge to support another alike container can be seated.
21128356_1 (GHMatters) P107034.AU.1 5/09/24
The blank may include a plurality of fold lines demarcating the different parts of the container such as the side wall panel, the extension panel and the ledge panel.
The surface formed by the ledge panel may be a ledge.
The sub-panels may include pairs of side wall panels hinged to opposing edges of the base panel.
Suitably, the sub-panels include panels that extend from the side wall panels such as a ledge panel, an end extension panel, and an extension panel.
The ledge panel may be hinged to one pair of the side wall panels.
The extension panel may be hinged to the side wall panel and/or the ledge panel.
The extension panel may include a fold line that is substantially parallel to an edge of the base panel which divides the extension panel into two panels.
The blank may be a single integrally formed blank.
According to a second aspect of the present invention, there is provided a single integrally formed blank that can be erected into a container comprising: a base panel; a side wall extending about the base panel by a first fold line, such that when the blank is erected, the side wall is folded upwardly of the base, and includes a plurality of sub-panels that are arranged relative to each other to form corners in the side wall between each adjacent sub-panel to form a receptacle; a ledge panel extending from the side wall, such that
21128356_1 (GHMatters) P107034.AU.1 5/09/24 when the blank is erected, the ledge panel forms a surface on which an alike container can be seated; an extension panel extending from the ledge panel, such that when the blank is erected, the extension panel is inclined relative to the side wall and forms a strut that supports the ledge panel and surface of the container; and a gusset panel interconnecting sub-panels of the side wall, so that at least part of the receptacle formed when the blank is erected is liquid tight.
In the operative position, the ledge panel forms a ledge to support another alike container can be seated.
The blank may include a plurality of fold lines demarcating the different parts of the container such as the side wall panel, the extension panel and the ledge panel.
The surface formed by the ledge panel may be a ledge.
Suitably, the sub-panels include panels that extend from the side wall panels such as a ledge panel, an end extension panel, and an extension panel.
The sub-panels may be pairs of side wall panels hinged to opposing edges of the base panel. Suitably, the ledge panel is hinged to one pair of the side wall panels. The extension panel may be hinged to the side wall panel and/or the ledge panel.
The extension panel may include a fold line that is substantially parallel to an edge of the base panel which divides the extension panel into two panels.
According to a third aspect of the present invention, there is provided a container made from a blank of a
21128356_1 (GHMatters) P107034.AU.1 5/09/24 foldable material comprising: a base panel; a first pair of side wall panels hinged to opposing edges of the base panel; a pair of ledge panels, wherein each said ledge panel is hinged to a respective one of the first pair of side wall panels about a fold line that is substantially parallel to an edge of the base panel; a first pair of extension panels, wherein each said extension panel is hinged to a respective one of the pair of ledge panels about a fold line that is substantially parallel to an edge of the base panel; a second pair of extension panels, wherein each said extension panel of the second pair of extension panels is hinged to a respective one of the first pair of extension panels about a fold line that is substantially parallel to an edge of the base panel; a pair of opposed end extension panels hinged to at least one of: the first pair of side wall panels, the pair of ledge panels, the first pair of extension panels and the second pair of extension panels; and a second pair of side wall panels hinged to opposing edges of the base panel and being connected to the pair of opposed end extension panels, hinged to each of the first pair of side wall panels, by a gusset panel, whereby when the container is formed from the blank, each one of the extension panels is folded to overlie an inner face of the associated side wall panel, with at least the first pair of extension panels being inclined relative to the side wall panel to thereby form a strut that supports the ledge panel of the container, such that each one of the ledge panels forms a ledge extending at least part way around an upper periphery of the container and the gusset panel forms a liquid tight web between the second pair of side wall panels and the pair of opposed end extension panels hinged to each of the first pair of
21128356_1 (GHMatters) P107034.AU.1 5/09/24 side wall panels.
The gusset panel may provide resistance to leakage of fluid contained in the container, particularly at the corners of the side walls. The gusset panel may increase structural integrity of the container by reducing the likelihood of fluids penetrating the panels, particularly through the exposed ends of the panels. These advantages are achieved at least in part because the formed gussets raise the exposed edges of the side walls above the base panel.
The gusset panel may be joined to a side wall panel and an end extension panel.
The gusset panel may be formed from the blank. For example, folds may be made at the corners of the side wall panels to form the gussets. In this embodiment, the gussets are integral to the blank.
Suitably, the gusset panel extends along the entire height of the pair of opposed end extension panels. Increasing the height of the gusset panel may increase the resistance to leakage of fluid and the structural integrity of the container.
For containers with long wall sections, such as those used to store whole fish, the stiffness or rigidity of the walls are important to resist bulge or buckling caused by the internal pressures applied to the container by the product. Side wall stiffness is also important to resist damage from the end to end loads and impact which typically occur on packing lines. In this respect, the ledge may improve the stiffness or rigidity of the walls to increase the structural integrity of the container.
21128356_1 (GHMatters) P107034.AU.1 5/09/24
The ledge can extend completely around the upper periphery of the container.
The ledges formed by the ledge panels can meet intermediate of each one of the second pair of side wall panels.
The container can further comprise apertures in each one of the second pair of side wall panels, wherein the apertures function as handles.
The container can further comprise cutouts configured to form a mitre joint between intersecting portions of the ledge when a container is made from the blank.
The container can comprise cutouts in the ledge panels, first pair of extension panels and end extension panels, wherein the cutouts are configured such that when a container is made from the blank, a mitre joint is formed between intersecting portions of the ledge.
The blank is preferably made of a cellulose-based material, such as fibreboard or corrugated board.
Preferably, the end extension panels are folded at right angles to the associated extension panels such that the extension panels meet intermediate of each one of the second pair of side wall panels.
Preferably, a free edge of each said end extension panel of the second pair of end extension panels rests upon an inner face of the base panel.
The container may include a lid. The lid may be used to retain moisture and/or odours within the container.
The lid may be connected to the container by a hinge.
21128356_1 (GHMatters) P107034.AU.1 5/09/24
The lid may be integrally formed to the container.
The lid may be any one of a hand erect cap lid, a cap end slotted tray lid, a cap side slotted tray lid or a corner cut lid.
The lid may be made from a blank of a foldable material comprising: a lid base panel; a first pair of lid side wall panels hinged to opposing edges of the lid base panel; a second pair of lid side wall panels hinged to opposing edges of the lid base panel; and a pair of opposed end extension panels hinged to at least one of the first lid side wall panel, whereby when the lid is formed from the blank, the opposed end extension panels are folded to overlie an inner face of the associated first lid side wall to form a sidewall of the lid.
One of the first lid side wall panels may be connected to the container to form a hinged lid.
At least one side of the blank may be covered with or include a layer to provide resistance to fluids, particularly water. Suitably, either or both layers of the board or corrugated board are covered with or include a layer to provide resistance to fluids, particularly water. This layer may also be applied to at least one side of the blank used to form the lid.
Suitably, the layer is a polymer coating or film. Examples of suitable polymers include polyethylene, nylon, PET, polypropylene and metallised versions of these polymers.
In this specification, the term "connected" is used to encompass parts of the blank that are formed separately
21128356_1 (GHMatters) P107034.AU.1 5/09/24 and subsequently joined together or integrally formed regions of the blank that are demarcated by fold lines.

Fig. 14 is a graph illustrating the compressive load vs compressive extension of a container according to a fourth embodiment of the invention.
One embodiment of a blank from which a container according to the invention is made is marked as 10 in Figure 1.
The blank 10 has a plurality of panels demarcated by pre formed fold lines that enable the blank to be folded to form the container.
Specifically, the blank 10 has a base panel 11 to which are hinged two opposed pairs of side wall panels 12, 13 and 14, 15. Side wall panels 12 and 13 of the first opposed pair of panels are hinged to the base panel 11 by fold lines 24, 26 while side wall panels 14 and 15 of the second pair are hinged to the base 11 by fold lines 25, 27.
Side wall panel 12 has a ledge panel 16 hinged to it by fold line 30, which is parallel to fold line 24. Corresponding side wall panel 13 has a ledge panel 19 hinged to it by fold line 33, which is parallel to fold line 26.
Ledge panel 16 has a first extension panel 17 hinged to it by fold line 31, which is parallel to fold line 30. Corresponding ledge panel 19 has a first extension panel 20 hinged to it by fold line 34, which is parallel to fold line 33.
21128356_1 (GHMatters) P107034.AU.1 5/09/24
First extension panel 17 has a second extension panel 18 hinged to it by fold line 32, which is parallel to fold line 31. Corresponding first extension panel 20 has a second extension panel 21 hinged to it by fold line 35, which is parallel to fold line 34.
A pair of end extension panels 22, 23 is hinged to side wall panel 12 and second extension panel 18 by fold lines 29, 28 with fold lines 30, 31 and 32 continuing into end extension panels 22 and 23. Correspondingly, a pair of end extension panels 22, 23 is hinged to side wall panel 13 and second extension panel 21 by fold lines 29, 28 with fold lines 33, 34 and 35 continuing into end extension panels 22 and 23.
Cutouts 36, 37 are situated in panels 16, 17, 22 and 16, 17, 23 and are suitably shaped to form a mitre joint between the ledge formed by panel 16 and the ledges formed by extension panels 22 and 23, when the container is assembled from the blank 10. Correspondingly, cutouts 38, 39 are situated in panels 19, 20, 22 and 19, 20, 23, and are suitably shaped to form a mitre joint between the ledge formed by panel 19 and the ledges formed by extension panels 22 and 23, when the container is assembled from the blank 10 (see Fig. 2).
The mitre joints provide a substantially continuous surface extending around the upper surface of the container 50. The mitre joints also improve the strength container against end and side impact.
Side wall panels 14 and 15 include apertures 41 and 40, respectively. Apertures 41 and 40 function as handles when the blank 10 is assembled into the container to allow the container to be easily transported.
21128356_1 (GHMatters) P107034.AU.1 5/09/24
Side wall panels 14 and 15 are connected to the pair of end extension panels 22 and 23, respectively, by gusset panels 42.
In the embodiment illustrated in Figures 1, 4 and 7, the gusset panels 42 are formed separately and joined to the blank between a side wall panel and an end extension panel. The gusset panel 42 can be joined to the blank by gluing or some other appropriate technique.
The gusset panel 42 comprises three edges forming a triangle shape having two diagonal edges extending away from a corner of the base panel 11. The diagonal edges are connected to the blank while the horizontal edge is free floating.
In an alternative embodiment, gussets may be integrally formed from blank 10. For example, a region of the side wall panels and end extension panels may be scoured and folded to form the gussets.
In Figure 1, when the blank 10 is assembled into container 50, gusset panels 42 fold inwardly to form inverse pyramidal-shaped webs at the base of the container between the side wall panels 14 and 15 and the pair of end extension panels 22 and 23. This raises the exposed edges of the side wall and end extension panels away from the base panel and reduces fluid leakage from produce stored in the container. In Fig. 1, the gusset panel 42 extends about one quarter the height of the end extension panels 22, 23.
In contrast, conventional containers without such webs have a higher likelihood of fluid leaking into the gap between side wall panels 14, 15 and the end extension panels 22 and 23. When this occurs, fluid may contact the exposed edges of side wall panels 14, 15 and of end
21128356_1 (GHMatters) P107034.AU.1 5/09/24 extension panels 22 and 23. This may accelerate degradation of the container.
Fig. 2 illustrates a top perspective view of a container 50 that has been constructed from the blank 10 illustrated in Fig. 1.
The ledge formed by ledge panels 16 and 19 is visible in this diagram and extends part way around the upper periphery of the container 50. The ledges that are parallel to the side wall panels 14 and 15 are formed from the end extension panels 22 and 23.
In order to construct the container 50 from the blank 10, panels 12, 16, 17 and 18 are folded about fold lines 24, 30, 31 and 32, respectively. Similarly, panels 13, 19, 20 and 21 are folded about fold lines 26, 33, 34 and 35, respectively. The second extension panels 18 and 21 are folded such that they overlie an inner face of their associated side wall panels 12 and 13. Also, a free edge of each of the second extension panels 18 and 21 rests upon an inner face of the base panel 11. The second extension panels 18 and 21 can be fixed to the inner face of their associated side wall panels 12 and 13 by gluing or some other appropriate technique. Thus, the thickness of the container sides comprising panels 12, 13, 18 and 21 is equal to twice the thickness of the material from which the blank 10 is made. This adds to the compressive strength of the container 50. The end extension panels 22 and 23 are then inwardly folded about fold lines 29 and 28, respectively. The panels 22 and 23 are folded such that they are perpendicular to their associated side wall panels 12 and 13.
Next, side wall panels 14 and 15 are folded inwardly about fold lines 25 and 27, respectively. When folded, the side wall panels 12, 13, 14 and 15, and the base panel define a
21128356_1 (GHMatters) P107034.AU.1 5/09/24 receptacle.
The side wall panels 14 and 15 are perpendicular to the base panel 11 and gusset panels 42 form a web at the base of the container which acts as a barrier against leakage of fluid from the container 50.
An outer face of the end extension panels 22 and 23 is then fixed to an inner face of the side wall panels 14 and 15 by an appropriate technique such as gluing. Thus, the thickness of the container ends comprising side wall panels 14, 15, and end extension panels 22 and 23 is equal to three times the thickness of the material from which the blank is made (Figs. 2 and 5). This adds to the compressive strength of the container 50.
The ledge panels 16, 19 as well as end extension panels 22 and 23, form a ledge that extends at least part way around the upper periphery of the container 50. In the embodiment illustrated in Figs. 2 and 5, the ledge is substantially perpendicular to the side wall panels 12 to 15. However, it can be appreciated that the angle of the ledge relative to the panels 12 to 15 can be varied as necessary.
The ledge provides a substantial support to enable a plurality of containers 50 to be stably stacked on top of each other. The ledge also adds to the torsional strength of each of the containers 50.
The first extension panels 17, 20 as well as the end extension panels 22 and 23 bound by fold lines 31/32, and 34/35, are inclined relative to their associated side wall panels to form struts which increase the strength of the ledge to support a load (e.g. an alike container) placed on the ledge.
21128356_1 (GHMatters) P107034.AU.1 5/09/24
These panels also form a void (not specifically indicated in Fig. 2) underneath the ledge.
The width of the end extension panels 22 and 23 is such that when the blank 10 (illustrated in Fig. 1) is assembled, the folded end extension panels 22 and 23 do not cover the apertures 40 and 41 in panels 14 and 15. This is shown in Fig. 2. In this manner, a person's fingers can extend completely through the apertures 40 and 41 to facilitate lifting and transportation of the container.
Fig. 3 is a bottom perspective view of the container shown in Fig. 2.
Fig. 4 is a view of a blank 110 from which a container 150 according to a second embodiment of the invention is made. The blank 110 is identical to the blank 10 illustrated in Fig. 1 except that the end extension panels 22 and 23 meet when a container 150 (illustrated in Fig. 5) is constructed from the blank 110 of Fig. 4. The abutment of the end extension panels 22 and 23 increase the strength of the ledges formed from panels 22 and 23. In the embodiment illustrated in Fig. 4, a person's fingers can still at least partially extend into the apertures 40 and 41 to facilitate transportation of the container.
Fig. 6 is a bottom perspective view of the container shown in Fig. 5.
In the embodiments illustrated in Figs. 1 and 4, liners may be included on the inside of containers 50 to restrict movement of fluid into and out of the container. The liners may cover apertures 40 and 41 to prevent fluid from flowing through them.
21128356_1 (GHMatters) P107034.AU.1 5/09/24
Fig. 7 is a blank 210 from which a container 250 according to a third embodiment of the invention is made. The blank 210 is identical to the blank 110 illustrated in Fig. 4 except that apertures 40 and 41 are absent. Removing apertures 40 and 41 improves the ability of the container 50 to reduce leakage by reducing the number of openings through which fluid can enter or exit the container.
To enhance the ability of the container to retain moisture or fluid from the produce, the container may include a lid. The lid may be formed integrally with or attached to the container.
The container of Fig. 7 includes a lid formed from blank 55 (Fig. 8). Blank 55 has a base panel 61 to which are hinged two opposed pairs of side wall panels 62, 63 and 64, 65. Side wall panels 62 and 63 are hinged to the base panel 61 by fold lines 68, 69 while side wall panels 64 and 65 are hinged to the base 61 by fold lines 70, 71. A pair of end extension panels 66, 67 is hinged to side wall panel 62 by fold lines 72, 73.
In order to construct the lid 55, panels 62, 63, 64 and 65 are folded about fold lines 68, 69, 70 and 71, respectively. The end extension panels 66 and 67 are folded such that they overlie an inner face of side wall panels 64 and 65, respectively. The free edge formed by side wall panel 63 is fixed to the outer face of side wall panel 13 by gluing or some other appropriate technique to form a hinge about which the lid 55 pivots.
Fig. 9 illustrates a top perspective view of a lidded container 250 that has been constructed from blanks 210 and 55 illustrated in Figs. 7 and 8.
Figs. 11, 12, 13A and 13B illustrate blanks from which other types of lids which may be used with the container
21128356_1 (GHMatters) P107034.AU.1 5/09/24 are formed. Specifically, Fig. 11 illustrates a blank used to form a hand erect cap lid, Fig. 12 illustrates a corner cut lid which is fixed to the outer faces of side wall panels 12, 13, 14 and 15 by gluing or some other appropriate technique to seal the contents of the container, and Figs. 13A and 13B illustrate cap lids with end extension panels extending from different side wall panels.
Each of the blanks illustrated in Figs. 11, 12, 13A and 13B comprise a base panel 61 to which are hinged two opposed pairs of side wall panels 62, 63 and 64, 65. Side wall panels 62 and 63 are hinged to the base panel 61 by fold lines 68, 69 while side wall panels 64 and 65 are hinged to the base 61 by fold lines 70, 71. A pair of end extension panels 66, 67 is hinged to side wall panel 62 by fold lines 72, 73.
In order to construct the respective lids, panels 62, 63, 64 and 65 are folded about fold lines 68, 69, 70 and 71, respectively.
With respect to Fig. 11, the end extension panels 66 and 67 are folded such that they overlie an inner face of side wall panels 64 and 65, respectively. Panels 64B and 65B are then folded over panels 64A and 65A, respectively, such that tabs 75 engage holes located along fold lines 70 and 71, respectively.
With respect to Fig. 12, panels 62, 63, 64, and 65 are fixed to the outer face of a side wall panel of the container by gluing or some other appropriate technique.
With respect to Fig. 13A, the end extension panels 66 and 67 are folded such that they overlie an inner face of side wall panels 64 and 65, respectively. Similarly, the end extension panels 66 and 67 are folded such that they
21128356_1 (GHMatters) P107034.AU.1 5/09/24 overlie an inner face of side wall panels 62 and 63, respectively, in Fig. 13B.
In the illustrated embodiments of the container, both sides of the blanks 10, 110 and 210 are covered with a hydrophobic polymer layer to provide resistance to water and moisture. A similar layer is also applied both sides of the blanks used to form the lids illustrated in Figs. 8, 11, 12A, 12B, 13A and 13B.
Fig. 10A illustrates the cross-sectional profile of blanks 10, 110 and 210 in the form of a corrugated board. The corrugated board comprises a corrugated medium 80 sandwiched between two multi-ply laminates 82. Each multi ply laminate 82 comprises an outer layer of light weight paper 84, a polymer barrier layer 86, and an inner cellulose-based liner 88. Suitably, the inner cellulose based liner 88 is a Kraft liner. The corrugated mid section 80 imparts bending strength to the container while multi-ply laminates 82 impart fluid resistance to the container.
Fig. 10B illustrates a process in which the multi-ply laminate 82 may be formed. During the process, a layer of molten polymer 90 extruded from an extruder/coating die 92 is fed between two sheets of paper 94A and 94B. These layers of paper and molten polymer are passed between chill roll 96 and pressure roll 98 where they are pressed together to form the multi-ply laminate 82. The formed multi-ply laminate 82 is then wound into a roll 100 via stripper roller 102 to be processed into blanks 10, 110 and 210.
The container 250 may further include a liner covering the inner surface of the container to reduce leakage.
