Description

FIELD OF THE INVENTION

This invention relates to a dunnage assembly, a kit of parts for a dunnage assembly, and a method for assembling a dunnage assembly.

BACKGROUND OF THE INVENTION

When transporting goods, it is important to protect the goods from damage during transit. The general term for material used to protect goods during transit is ‘dunnage’. Dunnage can take various forms, including fixed structures that are used to fill gaps between items, to reduce or prevent movement of the items during transit. Commonly used dunnage elements for this purpose include steel rachet stays, plastic or polystyrene elements, and air bags.
Steel stays are relatively expensive and bulky. They are not width-adjustable, so additional stays may be required when filling a larger gap. Air bags typically comprise plastic film and are not readily reusable or recyclable.
It would be desirable to provide an alternative dunnage solution that can readily adjusted to accommodate differently sized gaps, while preferably being environmentally friendly and relatively inexpensive.
In this specification, where reference has been made to external sources of information, including patent specifications and other documents, this is generally for the purpose of providing a context for discussing the features of the present invention. Unless stated otherwise, reference to such sources of information is not to be construed, in any jurisdiction, as an admission that such sources of information are prior art or form part of the common general knowledge in the art.
For the purpose of this specification, where method steps are described in sequence, the sequence does not necessarily mean that the steps are to be chronologically ordered in that sequence, unless there is no other logical manner of interpreting the sequence.
It is an object of the present invention to provide a dunnage assembly which overcomes or at least partially ameliorates some of the abovementioned disadvantages or which at least provides the public with a useful choice.
