Waste transfer packers

Claim 1

A structure adapted to form part of an end wall of a vehicle transfer container body for carrying and transporting compacted loose material, such as domestic waste, said structure comprising: a container including a container end wall portion having a rectangular opening forming therein for cooperation with a spigot of a horizontally acting packer, said opening having a top, a bottom, opposed sides, and including a pair of inwardly openable upper and lower doors, said upper door being biassed to yieldably maintain it in a closed position and being hinged at the top of said opening, said upper and lower doors arranged to open inwardly by contact with the spigot and on relative movement of the structure theretowards, the upper of the pair of doors having a main portion and a distal portion connected to the main portion and capable of flexing inwardly of said container body along an intermediate horizontal hinge between said main and said distal portions so that when opened inwardly said distal portion can flex upwards to a position corresponding to a forward-sloping surface of loaded material within the container, the closing bias of the upper door being effective, on withdrawal of the spigot, to move said door with the distal portion flexed and moving down over said surface of loaded material first to a position where said intermediate hinge is rotated to a position outside the end wall portion of the container so as to allow the distal edge of the said distal portion to clear the surface of loaded material, whereafter the upper door straightens out to form a closure with said intermediate hinge approximately in the plane of the container end wall portion.
