ABSTRACT:
For emptying a garbage room in a multistory residential building, a garbage container is placed in the garbage room, which container has a transport duct between the lower portion of the container and a garbage truck collection chamber, which can be evacuated to produce suction in the duct and thus move the garbage, usually in garbage bags. According to the invention, the garbage container is provided with an externally operable valve at one inlet for garbage coming from a garbage chute and an opening for inlet of air, which opening is also provided with a sealable valve. For emptying, during a first evacuation phase, both valves are closed and during a second evacuation phase, the valve at the air intake is open. The garbage bags are thus evacuated of air during the first evacuation phase and pressed together into a significantly smaller volume by the air flowing in during the second evacuation phase, at the same time as they are removed through the transport duct.
