A working container for electrical household food preparation appliances including a lower transmission component connected by a shaft to a rotary working tool arranged in a receptacle, wherein the shaft runs through the bottom of the receptacle and is rotatably mounted in a bearing housed in the bottom of the receptacle by virtue of the lower transmission component having an upper flange ring forming a reservoir around the shaft. The inner wall of the flange ring enables the collection of oil coming from the bearing and prevents the projection of oil onto a wall of the working container and permits the oil to drain to the bottom of the reservoir.
