Definitions

• THIS INVENTION relates to a collapsible bin or crate, and, in particular, to the style of collapsible bin or crate wherein, in the process of collapsing, side panels fold along a vertical axis.
• collapsible bins or crates Various forms of collapsible bins or crates have been devised. Most usually, the collapsing involves panels that are folded together along hinges established along a combination of vertical or horizontal edges. In some prior designs, the bin or crate is collapsed by folding of various panels along hinge lines that bisect the panels. In these latter arrangements, the hinge line can be located in either of a vertical or a horizontal direction.
• Prior Australian Patent Specification Nos. 68129/87 and 46290/85 set out descriptions of collapsible crates in which side panels fold along horizontal hinge lines. In prior Australian Patent Specification No. 44120/85, the crate collapses by folding along vertically aligned hinge lines that bisect opposed side panels.
• the present invention achieves its object in the provision of: side walls for containing goods therebetween, said side walls being collapsible on vertical hinge lines into a flat pack; and a pallet to support the side walls thereover providing a floor thereto to contain produce therein; characterised in that: a plurality of the said pallets are stackable one above the other; and a respective plurality of collapsed side walls are so dimensioned that in a side by side assembly of a predetermined number of vertically stood flat side walls, said side-by-side assembly nests in a stable configuration on the uppermost pallet of the pallet stack.
• the height of the walls of the collapsible crate may be varied by selection of an appropriate assembly of panels depending upon what is to be stored therein with lower vertical heights when the collapsible crate is to be used to contain objects that cannot be loaded onto each other to too great a depth.
• the bin or crate of this invention can comprise walls of a chosen height over a pallet which is stackable and dimensioned to receive a set number of collapsed walls stacked side by side over a vertical stack of their respective pallets. This arrangement reduces the volume of the bins to a particularly useful degree, creating a collapsed pack which is readily handled.
• the wall panels and other parts, pallet, covers, etc. for a crate of the above kind can each be produced as a single moulding of desired dimension from a polyethylene structural foam in the form of an extended plate form panel with upstanding flanges about the periphery and traversed across the surface of the panel to provide a desired rigidity.
• the hinges may comprise integrally moulded hinge parts spaced to interdigitate when two panels are butted to receive a hinge pin therethrough.
• Use of structural foams and appropriate strengthening ribs enables a bin or crate to be realised in weight ranges of 28 to 40 kg having standard pallet floor dimensions.
• the ribbing is preferably provided outside the box structure so that fruits, etc., therein are not damaged by the ribs.
• the same techniques can be applied to walls of a range of heights so that a small number of wall panels can be produced over a desired range to permit shallow depths when fruits, etc., cannot be packed to any great depth.
• the bin or crate is readily produced with pallets able to be stood over crates below to gain useful storage volumes with the full height of a transport, etc., able to be used by stacking of crates.
• foam as a material of construction allows the use of lower pressure tooling in moulding which is cheaper than other higher pressure tooling.
• Strength is achieved by adding framing and flanges to the panel, pallet, etc.
• FIG. 1 is a perspective view of a bin or crate in accordance with the present invention showing how the walls may be collapsed;
• FIG. 2 is a plan view of the side walls of the crate or bin of FIG. 1;
• FIG. 3 is a view of one side wall of the crate or bin of FIGS. 2 and 3;
• FIGS. 4 and 5 are detailed views of wall panel components as might be used in the crate or bin of FIGS. 1 to 3;
• FIGS. 6 to 8 are detailed views of a corner hinges of a crate or bin as in FIGS. 1 to 3;
• FIGS. 9 to 11 are plan and sectional views of a pallet which may be employed as the base of a bin or crate in accordance with the present invention.
• FIG. 12 shows how a plurality of bins or crates might be collapsed and shipped;

• FIGS. 20 to 23 show features of a cap which might be used with the lid of FIGS. 14 to 19.
• a bin or crate may be formed with vertical interconnected walls 10 supported over a pallet or tray bottom (not shown). Side walls 11 and 12 collapse towards each other when side walls 13 and 14 are each collapsed about hinges 15 and 16 respectively. By this means the bin or crate may be collapsed for return and reuse.
• the crate or bin 10 is provided with corner hinges 22 to 25 which open to 90° to form a square or rectangular shape.
• Hinges 26 and 27 open to 180° to form side walls that are collapsible onto themselves between the other two connecting walls to form a flat collapsed pack.
• Side walls are formed by identical sections 32 and 33 and 34 and 35 differing only in length.
• the lugs such as 110 provided around the crate walls are to engage in slots in a perimeter flange of the pallet bellow as described below with reference to FIG. 13.

• the hinge pin 71 is threaded therethrough and the bottom can be plugged by a plug 72 to retain a hinge pin or rod 71 therein.
• the extra ring of material adds to strength vertically to assist in supporting against downward loads. It also provides a buffer against impacts which might otherwise damage the hinge pin and its hinge parts. A bent pin would adversely affect the operation of the crate.
• FIG. 5 is seen the section A-A of FIG. 4 to show in section the shape of hinge pin locator 70 which exists in hinge part 69 on panel 72 to locate hinge pin 71 therein.
• FIGS. 6 and 7 show a mid-panel hinge in greater detail.
• the panels 60 and 61 are provided with hinge parts arrayed at regular spacings along their vertical edge. Hinge parts 58 and 59 only are drawn for convenience.
• the hinge parts and their attached panels 60 and 61 are connected by a pin or rod 71 extended therethrough up the height of the bin or crate.
• hinge parts come together to be connected by a pins at 64.
• Panels 54 and 55 may comprise sheet form plates which are ribbed thereover to strengthen them. At their periphery they may have a perpendicular flange thereabout which engages against the flat section of each hinge part such as 65 to limit the degree of opening of the panels to 90° or 180° as desired.
