Abstract
Abstract A filler cap for the container of a household mixer with a locking arrangement including a filler tube with a filling opening to receive the products to be mixed, which is arranged concentrically to the axis of rotation of the mixer and a sealing ring. The filler tube is provided with ribs tangently positioned to the filling opening and extending from the filling opening to the sealing ring which is positioned at a lower side of the filler tube. In operation the ribs produce an effect tending to hold the filler cap in its position on the container.
