DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a flat packing container and to clips for use in storage of demounted flat packing containers.
BACKGROUND OF THE INVENTION
Containers for automobile components, other engineering articles or bulk fluids are routinely composed of wooden panels held together by steel clips. Such arrangements are known from U.S. Pat. No. 3,323,674, U.S. Pat. No. 4,024,977, U.S. Pat. No. 4,083,464 and many other disclosures. In these arrangements the container may be dismantled by removal of the clips. Although the separate panels may be stacked together the clips are often lost or damaged. Usually an empty container is used for storage of the clips. This is inconvenient and is a waste of space and materials. In addition each set of panels may become separated from the requisite number of clips.

DETAILED DESCRIPTION OF THE INVENTION
In accordance with a first aspect of the present invention a container comprises separate laminar panels, a multiplicity of retaining clips, the retaining clips being adapted to secure the panels when the container is erect, and a multiplicity of storage clips, each storage clip comprising two legs, a first leg having a first foot arranged to be received beneath the panels when the latter are stacked and the second leg having a second foot remote from the first leg adapted to be received in a recess in the top panel of the stack, the length of the first leg being arranged so that the top panel of the said stack can be stacked with the internal face directed toward the adjacent panel with a restraining force being applied by the storage clip to the stack to restrain separation of the panels.
A container in accordance with the present invention confers several advantages. The dimensions of the retaining clips may be standardised irrespective of variations in the thickness or number of panels to be retained by the storage clips. In addition the storage clips may perform further functions as described below.
Storage of the stacked panels with the upper panel facing inwardly prevents damage to dunnage or other fixtures which may be provided on the internal surface of the panels. This is important in preservation of the container for repeated use. Furthermore the internal surfaces of the container are kept clean so that the contents of the container are not contaminated before the container is erected for use. Storage of the stacked panels is facilitated and the stacks may in turn be stacked together.
In preferred embodiments of the invention the container includes a rectangular base block, the base block incorporating surfaces adapted to receive and retain a clip located at a corner of the block when the container is erect. Location of the clips at the corners of the base block serves to protect the latter from damage in use and prevents the clips from becoming separated from the respective container. The surfaces may comprise corners or edges of the base block or recesses in the block.
In further preferred embodiments of the invention one or both feet of the storage or retaining clips includes a formation defining an engagement for a tool. The formation may comprise a protrusion or aper
