  • Patent number: 10940946
    Abstract: A system for disposing waste in a transportation system includes a collection device for collecting waste in the cabin of the transportation system, a separate receptacle device for receiving collected waste from the collection device, and a connection device for selectively connecting the collection device to the receptacle device in order to deliver collected waste from the collection device into the receptacle device. The receptacle device is arranged in a lower deck region underneath the cabin floor. The connection device extends into the receptacle device from the cabin floor and includes a closure that is arranged on or in the cabin floor. The collection device is mechanically couplable to the connection device, and includes a closable output opening aligned with the closure of the connection device in the coupled state.

  • Patent number: 10882618
    Abstract: A multifunctional container system for producing a container for a cargo compartment of an aircraft includes a first lateral container component, which forms a first lateral surface of the container that is at least partially beveled, a first lower resting surface having first fastening devices and a first top side, a second lateral container component, which forms a second lateral surface of the container that is at least partially beveled, a second lower resting surface having second fastening devices and a second top side, and a floor cladding. The cladding is selectively positionable between the first resting surface and the second resting surface, which enclose a continuous gap to each other and comprise a predetermined distance to each other and to create a protrusion that faces away from the first and second top side. The protrusion extends into a recess of a floor in a cargo compartment.
