Patent ID: 8516947

Claim:
In a food processing apparatus having functional elements for the processing of food, a housing assembly for protectively enclosing the elements, comprising: an integral, tubular thin-sheet, resilient, metallic wall assembly made from a single, thin-walled work piece with an open top and an open bottom with cross-sectional shapes and sizes that are substantially the same, a tubular body extending between the open top and the open bottom and having a uniform cross-sectional shape and size substantially the same as the cross-sectional shapes and sizes of the open top and the open bottom, said tubular body having a plurality of substantially straight, parallel, elongate, bent corners with interior angles that are substantially different from a right angle, a single, thin-walled, metallic, resilient, rectangular work piece in which the bent corners are formed, said resilient rectangular work piece having a pair of opposite sides extending between the open bottom and the open top and substantially spaced from the bent corners, said resilient rectangular work piece having a plurality of resilient, integral panels respectively extending laterally between the plurality of bent corners and vertically between the open top and the open bottom, at least one of said resilient, integral panels being in a stressed state with opposed bent corners of each panel being in a squeezed together state stressing the resilient panel into an arcuate shape; and an elongate weld joint extending between the open top and the open bottom and fixedly attaching together the opposite ends of the work piece to hold the at least one resilient, integral panel in the stressed state and arcuate shape; a closure base attached to the bottom of the wall assembly to close and support the open bottom of the wall assembly; and a closure top attached to, supported by and closing the open top.
