Abstract
Abstract A ventilating system for a garbage container. The container includes a vessel for receiving wastes and a cover. The receiving vessel has walls which are at least over portions thereof provided with air passage openings. An air-permeable intermediate wall is arranged spaced above the vessel bottom for carrying the waste. The intermediate wall is a grate with meshes formed by grate members. The meshes have a width which is substantially greater than the width of the grate members. The walls of the receiving vessel define air inlet openings in the region of the grate. Additional ventilation openings are provided in the walls underneath the opening of the receiving vessel. Spacer members for the wastes are provided on the inner surfaces of the walls of the receiving vessel at least over the portion of the walls which extends vertically above the grate. The cover is provided with air discharge openings.
