A collapsible tubular sleeve 51 has apertures 52 suitable to receive fork lift tines and a lid 61 engages its upper edge. The lower edge of the sleeve can rest on the ground around a pallet. Engagement between the sleeve and lid can be in the form of a downwardly facing channel on the lid or a horizontally facing channel on the wall. The sleeve could be formed of various plastics, card, layers of corrugated card, metal or plywood. Panels of the sleeve could be cut from a single blank and connected by hinges comprising fold lines and adhesive or a releasable latch at an overlap portion. A waterproofing coating such as wax, resin or paint could be applied. The corrugations could receive reinforcing filler or rods. The lid could be formed of various materials such as multilayer corrugated card, fibre reinforced plastic or wooden slats and a lip could be formed of L shaped plastic or paper pulp members attached by adhesive or screws. There can be insulation within the sleeve and/or around it in the form of wrapping or plates engaged with internal U shaped channels at either end of each panel. An aperture could allow access and coolant packages could be provided in within the sleeve. |
