Open the CIPO recordAbstract From the Canadian patent
A casing for hermetically encapsulated small refrigerators consists of a lower vessel (2) and an upper cover (3) interconnected along a welded edge (4). The side walls (5, 6) of the casing (1) are so inclined to each other beyond the weld seam (4) that a line (S1) drawn perpendicular to any desired wall section meets the opposite wall section at an angle different from 90° in at least one plane. The same applies to the base and walls of the cover (9 17) of the, casing (1). This results in a reduction in the noise radiated by the walls of the casing. Fig. 1.
