Abstract
A weighing scale housing (9) includes a base (21), vertical front (19), rear (17), and side (23,25) walls cooperating with the base to define a weighing chamber (3) containing a movable weighing pan (5), characterized in that at least one of the side walls includes a plurality of planar side wall segments (27, 29; 31, 33) arranged at an obtuse angle, the one side wall being mounted for movement along an arcuate path between an open position affording access to the weighing pan, and a closed position closing the weighing chamber. When in the open position, the side wall is adjacent the rear wall, and when in the closed position, the forward vertical edge (51,53) of one segment engages the rear surface of the front wall, and the rear vertical edge portion (55, 57) of the other segment engages an end portion of the rear wall, thereby tightly sealing the weighing chamber.
