DESCRIPTION:
BRIEF SUMMARY
This invention relates to goods containers of the knock down type comprised of sides adapted for mounting on a pallet directly or through a base. Such containers may, and usually do, include a lid.
In the past there have been many attempts to provide a container of the above type, one such is disclosed in the patent application number 81490/91 by the same applicant. However, there is always the need for a container which performs substantially as well as those which have gone before but is of a more economical design. This invention has taken the art of design for such containers a step further and provides a simple, robust, economical design which can withstand the rigours of transporting difficult products, such as liquids, which produce high stresses on the container under dynamic conditions. In addition the present invention provides a container design which minimises the problem of `bag pinch` which can now occur with some presently known containers.
Bag pinch occurs where under dynamic loads the container flexes in a way which provides gaps into which the plastic film liner bag of the container is forced by its liquid contents. When there is a reversal or reduction in the forces acting on the container the gaps close and the bag portions in the gaps can be damaged by pinching. Where pinching occurs the liner bag is most often weakened to the point where the likelihood of rupture becomes a possibility or, as can occur under some conditions, the pinching results in an immediate rupture of the liner bag.
Broadly stated, one form of the invention provides a container kit comprising a rectangular base ring which includes a pair of flanges inwardly directed from each side of the base ring thereby forming a horizontally inwardly directed mounting channel with an upper flange and a lower flange, mounting means on two opposite sides of the base ring including lugs extending inwardly to engage under the distal edges of battens on opposite sides of a pallet thereby to mount the base ring on a pallet, a first pair of rectangular side panels each having a top, two sides and a bottom with an out-turned lug means of thickness allowing entry into the mounting channel, a second pair of rectangular side panels each having a top, two sides and a bottom with an out-turned lug means of thickness allowing entry into the mounting channel, the width of the panels of the second panel pair between the sides thereof is less than the width of the panels of the first panel pair and the panels of the second panel pair are disposed between the first panel pair and prevent bodily movement of the panels of the first panel pair to disengage the lugs means thereof from the engaged base ring channels, and latching means to connect adjacent sides of the first and second panel pairs.
In another form the invention provides a container kit comprising a rectangular base ring which includes a first flange inwardly directed from each side of the base ring, a second flange inwardly directed from each side of the base ring narrower than the first flange and spaced from and parallel to the first flange, support pads on the first flanges located between the first and second flanges with a height less than the spacing between the first and second flanges, mounting means on two opposite sides of the base ring including lugs extending inwardly to engage under the distal edges of battens on opposite sides of a pallet thereby to mount the base ring on a pallet, a first pair of rectangular side panels each having a top, two sides and a bottom with an out-turned lug means of thickness allowing entry between the support pads and the second flanges on two opposed sides of the base ring, a second pair of rectangular side panels each having a top, two sides and a bottom with an out-turned lug means of thickness allowing entry between the support pads and the second flanges of the other sides of the base ring, the width of the panels of the second panel pair between the sides thereof is less than the width of the panels of the first panel pair and the panels
