A washing machine includes a liquor container suspended for oscillating in a housing. A washing drum is rotatable within the liquor container. A material-elastic collar is connected for establishing a liquid tight seal on the edge of a front-side loading opening of the liquor container, connecting with a housing-side loading opening, and with a door mounted for sealing the housing-side loading opening. A filling element is located on the door and has a curved outward portion in the shape of a truncated cone. The filling element has a surface area with at least one recess commencing close to a largest diameter of the cone portion, and forms a rising surface of sickle shape in the direction of the interior of the drum and toward a smallest diameter of the cone on the surface area thereof.
