ABSTRACT:
FIELD OF THE INVENTION
The invention relates to loading trays, commonly known by the term “pallets”, which can be used for transporting containers of liquids and, more particularly, to a pallet with a plastics platform.
BACKGROUND OF THE INVENTION
A known palletized container for liquids or for granular materials is constituted substantially by a plastics vessel, by a cage made of profiled metal sections surrounding the vessel, and by a quadrangular steel or plastics platform on which the vessel bears and to which the cage made of profiled metal sections is fixed.
The platform has stiffening ribs and, if it is made of plastics material, is formed by a moulding process, preferably by injection. Suitable support elements are formed on or applied to the four corners and to the centre of the lower surface of the platform.
A plastics platform of this type, however, can be produced only with plastics material of relatively low molecular weight and therefore has inadequate mechanical characteristics for certain applications. Moreover, it is quite expensive since it requires specific manufacturing tooling, in particular, an injection mould.
SUMMARY OF THE INVENTION
An object of the present invention is to propose a pallet with a plastics platform which is stronger and less expensive than known pallets.
This object is achieved in accordance with the present invention by a pallet comprising a plastics platform formed by a unitary hollow body having two major walls which are disposed opposite one another and at least one of which has protuberances which extend towards the interior of the hollow body so far as to contact the opposite major wall.
