A PALLET

[0001] This application is a divisional application of Australian Patent Application No. 2019268144, filed 21 November 2019, which in turn is a divisional application of Australian Patent No. 2017202183, filed on 3 April 2017, the entire contents of both being incorporated herein.

FIELD

[0002] The present invention relates to pallets, and more particularly but not exclusively to pallets that are used to transport boxed frozen meat and/or boxed chilled meat.

BACKGROUND

[0003] Pallets are of a generally square or rectangular configuration, with the pallet having an upper surface that is to receive product to be transported by the pallet. One such product is frozen meat.

[0004] A disadvantage of previous plastic pallets employed to transport frozen meat, is that they are constructed in a manner which means they must have a hollow inner drum like body cavity. They are also not adequately durable enough to withstand the impact of forklift tines when being employed in the daily functions for which they were designed. This inadequacy results in holes being punctured into the side walls of the previous pallets by fork lift tines when impacted in vulnerable side wall areas. The holes expose the pallets inner hollow cavity which then allows the ingress of contaminated water and debris that is likely to present a hygiene hazard to the frozen meat. Additionally, the previous pallets are designed to include a welded steel frame that is located inside the inner hollow cavity of the pallet in order to give it integral strength and stability. Without this steel frame, the pallet will not meet the required specification to handle the required load of frozen meat. Once the hollow inner cavities have been exposed by fork tine impact damage, the steel frame is subject to contaminated water and will rust resulting in additional potential contamination to the frozen meat which has a tendency to compound the hygiene issues associated with the previous pallets. These previous pallets are manufactured by a rotational moulding process.

OBJECT

[0005] It is the object of the present invention to overcome or substantially ameliorate the above disadvantage.

DESCRIPTION OF EMBODIMENTS

[0022] Figures 1 to 6 schematically depict a form of the plastic pallet 10 with two channels or recesses 28 in the top surface 11, and a set of two first passages 22 extending perpendicularly beneath the recesses 28. The pallet 10 may be of a rectangular configuration, however most preferably it is of a square configuration.

[0023] The pallet 10 is injection moulded, so that it is solid, that is it has no internal cavities, that if exposed (via damage to the pallet 10), do not pose a hygiene problem in respect of cleaning the pallet 10. The pallet 10 includes a top surface 11, a bottom surface 12, a pair of first side surfaces 13 and a second pair of side surfaces 14.

[0024] The side surfaces 13 and 14 are generally perpendicular to the surfaces 11 and 12. Additionally, the surfaces 13 are generally parallel but transversely spaced, and perpendicular to the surfaces 14. The surfaces 14 are generally parallel and transversely spaced.

[0025] The top surface 12 includes a first pair of edge portions 15, and an intermediate portion 16 equally spaced from the edge portions 15. The portions 15 and 16 extend generally parallel, with the edge portions 15 each being located adjacent a respective one of the side surfaces 13.

[0026] Located between the portions 15 and 16, are recessed surface portions 17, and planar portions 18 that are recessed relative to the portions 15 and 16, so as to be located at a lower height. Accordingly the portions 17 and 18 provide upwardly open recesses 28 located between the portions (projections) 15 and 16, that can receive the tines of a forklift. As seen in Figure 6 the portions 15 and 16 have approximately the same height, and provide co-planar surfaces upon which product to be transported can rest.

[0027] The surface 12 provides portions 20 that are generally parallel and transversely spaced, with two of the portions 20 being located adjacent the side surfaces 13.

[0028] The portions 20 are separated by portions 21, that are recessed relative to the portions 20 so that there is between the portions 20 downwardly open grooves or slots (recesses) 23 that can receive the tines of a forklift. The surface 12 also has apertures 24 that extend from the slots 23.

[0029] Extending between the side surfaces 13 are pair of first passages 22 that are configured to receive the tines of a forklift, that may be employed to lift the pallet 10. The apertures 24 extend so as to communicate with the passages 22.

[0030] Extending between the side surfaces 14 are the slots 23 (further passages) that are configured to receive the tines of a forklift, so that the material resting on the pallet 10 can be lifted. The slots 23 and recesses 28, as seen in Figure 2, are perpendicular to the passages 22.

[0031] With reference to Figure 1, as shown the width 25 of the slots 23 is approximately the same as the width 26 of the recesses 28. Additionally, as shown in Figure 6, the recesses 28 have a depth 31 that is greater than the depth 30 of the slots 23.

[0032] Passages 22 have a width 32 that is approximately the same as (but slightly greater than) the width 26.

[0033] As seen in Figure 2, the passages 22 have a depth that is greater than the depth of the slots 23.

[0034] Preferably, the pallet 10 includes high impact resistant reinforcing insert elements fixed in the corners and side walls, the reinforcing elements may be formed of metal or plastics material and they are embedded in the comers and perpendicular peripheral side walls of the pallet as described in Australian Patent 2009200360.

[0035] The above described preferred embodiment has a number of advantages, including the upper surface being configured to inhibit damage to frozen meat being transported by the pallet , while being injection moulded, enables the pallet 10 to be formed without any internal cavities or welded steel internal support frame, that may be exposed by damage to the pallet 10 and therefore introduce a hygiene issues.

[0036] Figures 7 to 11 schematically depict a form of the plastic pallet 50 with three channels or recesses 68 in the top surface 51, and a set of two first passages 62 extending perpendicularly beneath the recesses 68. The pallet 50 may be of a rectangular configuration, however most preferably it is of a square configuration.

[0037] The pallet 50 is injection moulded, so that it is solid, that is it has no internal cavities, that if exposed (via damage to the pallet 50), do not pose a hygiene problem in respect of cleaning the pallet 50. The pallet 50 includes a top surface 51, a bottom surface 52, a pair of first side surfaces 53 and a second pair of side surfaces 54.

[0038] The side surfaces 53 and 54 are generally perpendicular to the surfaces 51 and 52. Additionally, the surfaces 53 are generally parallel but transversely spaced, and perpendicular to the surfaces 54. The surfaces 54 are generally parallel and transversely spaced.

[0039] The top surface 52 includes a first pair of edge portions 55, and intermediate portions 56 spaced from the edge portions 55. The portions 55 and 56 extend generally parallel, with the edge portions 55 each being located adjacent a respective one of the side surfaces 53.

[0040] Located between the portions 55 and 56, are recessed surface portions 57, 58 and 59 that are recessed relative to the portions 15 and 16, so as to be located at a lower height. Accordingly the portions 5, 58 and 59 provide three upwardly open recesses 68. The two outer recesses 68 located between the portions (projections) 55 and 56, can receive the tines of a forklift. As seen in Figure 10 the portions 55 and 56 have approximately the same height and provide co-planar surfaces upon which product to be transported can rest.

[0041] The bottom surface 52 provides portions 60 that are generally parallel and transversely spaced, with two of the portions 60 being located adjacent the side surfaces 53.

[0042] The portions 60 are separated by portions 61, that are recessed relative to the portions 60 so that there is between the portions 60 downwardly open grooves or slots (recesses) 63 that can receive the tines of a forklift. The surface 52 also has apertures 64 that extend from the slots 63.

[0043] Extending between the side surfaces 53 is a set of three 'first' passages 62 configured to receive the tines of a forklift used to lift the pallet 50. The apertures 64 extend so as to communicate with the passages 62.

[0044] Extending between the side surfaces 54 are the slots 63 (further passages) that are configured to receive the tines of a forklift, so that the material resting on the pallet 50 can be lifted. The slots 63 and recesses 68, as seen in Figure 7, are perpendicular to the passages 62.

[0045] With reference to Figure 10, the width of the slots 63 is greater than the width of the recesses 68. Additionally, the recesses 68 have a depth that is greater than the depth of the slots 63.

[0046] Comparing Figures 10 and 11, passages 62 have a width that is approximately the same as the width of the recesses 68 in the top surface 51.

[0047] Figures 10 and 11 also show the passages 62 have a depth that is greater than the depth of the slots 63.

[0048] As with the previously described two-channel embodiment, the pallet 50 includes high impact resistant reinforcing insert elements fixed in the corners and side walls, the reinforcing elements may be formed of metal or plastics material and they are embedded in the comers and perpendicular peripheral side walls of the pallet as described in Australian Patent 2009200360.

[0049] The above described preferred embodiment has a number of advantages, including the upper surface being configured to inhibit damage to frozen meat being transported by the pallet , while being injection moulded, enables the pallet 50 to be formed without any internal cavities or welded steel internal support frame, that may be exposed by damage to the pallet 50 and therefore introduce a hygiene issues.

[0050] The three-channel pallet 50 is well suited to carrying cartons that have chilled meat (or a mix of frozen meat cartons and chilled meat cartons). The two-channel pallet 10 is better suited to frozen meat cartons only as the recesses 28 in the top deck are wide enough to allow chilled meat cartons to sag. Sag is not an issue with frozen meat cartons as the meat is completely rigid. Portions of the chilled meat cartons that sag into the recesses 28 are prone to damaging contact with tynes lifting the cartons from the top deck.

[0051] The relatively narrow recesses 68 in the top deck of the three-channel pallet 50 can be configured for use with a forklift fitted with three roller tynes (for example, the roller platens marketed by Cascade Corporation of Portland Oregon, USA). These are tynes fitted with rollers to smoothly roll under the cartons through the recesses 68. This facilitates lifting the whole load of frozen and/or chilled meat off the top deck. The load may then be efficiently transferred from the pallet into a refrigerated shipping container for export thereby leaving the pallet at the loading dock to be re-used.
