of August 11 that BonaHack and Sons. Ltd., of Basildon, Essex, had developed a light alloy five-ton goods container which, when empty, can be collapsed to occupy a volume 75 per cent, less than when fully extended. Fuller details of its design, which has been evolved in consultation with Hogg, Robinson and Capel-Cure, Ltd., the international shippers and forwarding agents, have now been released.
In essentials the Collapsitainer, as it is called, is a box made of aluminium alloy with folding sides. The standard version, suitable for a five-ton load, weighs 6 cwt. net, occupies 198 Cu. ft. when erected and 55 cu. ft. when collapsed. There are no detachable parts and it is claimed that two men can erect the container without use of tools in well under two minutes.
The desirability of sufficiently robust construction to withstand the stresses and impacts of normal handling by crane or fork-lift truck, and over-stowing by other containers or general cargo has been taken into account in its design.
Apart from its contribution to solving the problem of combining strength and lightness, the aluminium alloy construction makes the Bonallack Collapsitainer proof against vermin and corrosibn resistant. The measurements when fully extended are 7 ft. 6-1in. long, 5 ft. 1 in. wide and 5 ft. 2 in. high, and the containers can be stacked four high.
