This invention relates to load capping arrangements for stabilising loads comprising a plurality of articles, such as bottles arranged in an upright position.
The handling of bottles often requires them to be transported on pallets. This involves arranging the bottles in layers on a pallet with a slip sheet between each layer. A slip sheet can also be placed on the upper layer to stabilise it, but problems can be caused by the use of a slip sheet when the pallet is wrapped in a shroud, and as a result of the slip sheet failing to engage all the bottles in the upper layer, thereby failing to retain the upper layer of bottles.
According to one aspect of this invention, there is provided a load capping arrangement for stabilising a load which comprises a plurality of articles, wherein the load capping arrangement comprises a central region for engaging at least some of the articles, and a rim arrangement extending around the central region, the rim arrangement being deformable from a non-deformed condition to a deformed condition around the load.
The central region may have a substantially planar surface. The central region may be substantially planar.
The rim arrangement may be configured to engage a wrapping applied around the load to restrict the engagement of the wrapping with the articles.

In one embodiment, the central region may be formed of a rigid material and the rim arrangement may be formed of a resiliently deformable material. The central region may be formed of a plastics material.
The rim arrangement may be formed of an elastomeric material, such as a rubber material, and may be resiliently deformable between the non-deformed and the deformed conditions.
The rim arrangement may have an article engaging surface. The rim arrangement may be attached to the central region with the article engaging surface of the rim arrangement substantially co-planar with, or parallel to, the aforesaid planar surface of the central region when the rim arrangement is in the non-deformed condition. Alternatively, where the rim arrangement and the central region are substantially planar, the rim arrangement may extend co-planar with, or parallel with, the central region.
In a further embodiment, the central region may comprise a resilient sheet, which may be an elastomeric sheet, such as a rubber sheet.
The load capping arrangement may include reinforcing means on the central region. The reinforcing means may comprise a frame. The frame may be an outer frame, and may be arranged around the periphery of the central region.
The rim arrangement may be formed of a resiliently deformable material, such as an elastomeric material and may be formed of rubber. The rim arrangement may extend outwardly from the reinforcing means. The rim arrangement may constitute a part of the resilient sheet forming the central region. In one embodiment, the rim arrangement and the central region may be a unitary component.
The frame may be formed of a rigid material, for example a rigid plastics material.
In another embodiment, the central portion may comprise a rigid member, for example formed of a rigid plastics material.
The rim arrangement may comprise a foldable member attached to the central region. The foldable member may be connected to the central region at hinges.
The rim arrangement may comprise a plurality of foldable members attached to one another at hinges. The hinges may comprise hinge lines extending across the foldable member. The hinge lines may extend parallel to each other.
Each of the hinges may comprise a live hinge. Alternatively, at least some of the hinges may comprise mechanical hinges.
The rim arrangement may have a surface co-planar with the engaging surface. The rim arrangement may be substantially planar. Where the central region is substantially planar, the rim arrangement may be substantially co-planar with the substantially planar central region.

Embodiments of the invention will now be described by way of example only, with reference to the accompanying drawings, in which:
Referring to
The load capping arrangement 10 is generally rectangular in configuration and comprises a substantially planar central region 12 formed of a rigid plastics material. The central region has an edge 14 (see
In the embodiment shown in
The rim arrangement 15 is formed of a resilient elastomeric material, such as rubber, and is deformable from a non-deformed condition to a deformed condition. In the non-deformed condition, shown in
The central region 12 has a substantially a planar engaging surface 18 for engaging the bottles 102.
When the load capping arrangement 10 is disposed on the upper layer 104 of the bottles 102, it extends across the whole of the top layer 104 and its weight acts to stabilise the bottles 102. The rim arrangement 15 extends beyond the outermost bottles 102 and serves to retain them in position.
The load 100 may have a wrapping 108 (see
The rim arrangement 15 may be attached directly to the periphery 14 of the central region 12, where the rim arrangement 15 is substantially co-planar with the central region 12, when the rim arrangement 15 is in the non-deformed condition, as shown in
A third embodiment of the load capping arrangement 10 is shown in
The frame 20 is mounted on the sheet 19. The frame 20 is slightly smaller than the sheet 19, so that the outer periphery 22 of the frame 20 defines the position of the periphery 14 of the central region 12. The rim arrangement 15 extends outwardly from the outer periphery 22 of the frame 20.
In use, when the load capping arrangement 10 is disposed on the upper layer 104 of the stack of bottles 102, the outer periphery 22 of the frame 20 is substantially aligned with the outermost bottles 102 in the upper layer 104. The rim arrangement 15 extends outwardly therefrom and is deformed to the deformed condition, when the wrapping 108 is applied. In the deformed condition, in the same way as shown in
A fourth embodiment is shown in
Each rim portion 16 is foldably deformed when a wrapping is applied, as described above between a non-deformed condition, shown in
Each rim portion 16 comprises a plurality of planar foldable members 28 foldably attached to one another by a plurality of second hinge lines 30, where each of the second hinge lines 30 is in the form of a live hinge.
The fourth embodiment provides the advantage that the load capping arrangement can be used with different sized loads. This is shown in
Thus, as shown in
A fifth embodiment is shown in
In the fifth embodiment, each rim portion 16 comprises a deformable region 40 which, in the embodiment shown, is in the form of an apertured region.
The deformable region 40 defines a plurality of apertures in the form of elongate slots 42. The slots 42 are arranged in rows extending parallel to the periphery 14 to which the respective rim portion 16 is attached.
Each deformable region 40 comprises a plurality of elongate members 44, each of which extends the length of the aperture region. Connecting members 46 extend between adjacent elongate members 44, whereby the slots 42 are defined between adjacent elongate members 44 and adjacent connecting members 46.
Each elongate member is divided into a plurality of torsion bars 48, each torsion bar 48 extending between adjacent connecting members 46. For example, the torsion bar 48A shown in
The stiffness of the torsion bars 48 can be varied by varying the distance between adjacent connecting members 46.
The torsion bars 48 allow the rim portions 16 to deform from a non-deformed condition to one of a plurality of deformed conditions by bending, such bending occurring about the torsion bars 48. This has the advantage of reducing the stress on the material forming the rim portions, and helping to reduce permanent deformation. The bending of the rim portion 16 about a row of the torsion bars 48 causes the torsion bars 48 to twist about their longitudinal axes.
The bending of the rim portions 16, as shown in
In
A comparison of
There are thus described various embodiments of a load capping arrangement 10 which have the advantage that when disposed upon the top of an upper layer 104 of bottles 102 stacked on a pallet, all the bottles 102 in the upper layer 104 are stabilised, thereby allowing the pallet to be moved without the bottles 102 falling off. A further advantage is that each of the embodiments has a rim portion 16 which allows the pallet to be wrapped in a wrapping, such as a shroud without displacing any of the bottles 102 in the upper layer 104.
Various modifications can be made without departing from the scope of the invention. For example, the load capping arrangement could be any other suitable configuration, other than rectangular to correspond with the configuration of the load. Also the number of foldable members 28 in the fourth embodiment shown in
In a further modification, one or more of the live hinges can be replaced by mechanical hinges.
A sixth embodiment is shown in
The sixth embodiment of the load capping arrangement 10 differs from the fifth embodiment in that the load capping arrangement 10 further includes a lip arrangement 110 extending from the rim arrangement 15. The lip arrangement 110 may comprise a plurality of side lip members 112, each extending outwardly from a respective one of the rim portions 16.
Referring to
The rim arrangement 15 of the sixth embodiment of the load capping arrangement 10 further includes corner portions 114 at the corner regions between adjacent rim portions 16, shown in
The provision of the side lip members 112 and the corner portions 114 provides the advantage in the embodiment shown that they retain the bottles 102 at the peripheries and corners of the load. These bottles 102 can be unstable, and the side lip members 112 and the corner portions 114 stabilise these bottles. As can be seen from
Referring to
In use, when the load capping arrangement 10 is disposed on a load, the engagement surfaces 120 extend substantially vertically, thereby presenting a vertical face outwardly.
Referring to
One or more of the buffers 117 engages the engagement faces 120 along a respective one of the side lip members 112, and applies a force F to the load capping arrangement 10 to push the load capping arrangement 10 into a central position on the load, before wrapping 108 is applied.
In yet another modification, the deformable region 40 is in the form of a recessed region comprising a plurality of recesses. The recesses are elongate and include a membrane extending across each recess.
Further embodiments are shown in
The projections 150 are provided along the edges 142 of the apertures 42 closest to the periphery 14 of the central region 12. The projections 150 are configured to hold the outermost bottles 102. Each of the outermost bottles 12 is engaged by two projections 150.
