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.
Claims7
A filler cap for a household mixer of the type having rotary blades for mixing the media contained in the filler cap and a locking arrangement, comprising a filler tube to provide a funnel inlet for the media to be mixed, said filler tube having a filling opening positioned concentrically to the axis of rotation of the mixer;
- and a sealing ring connected to said filler tube, said filler tube including a plurality of ribs formed at the underside thereof and extending between a border of said filling opening and said sealing ring, said ribs being projected tangent to said filling opening so that vertically acting forces exerted by a ring of rotating liquid tending to be thrown upwardly due to rotation of said blades, are substantially negated due to interception and breaking up of the ring of rotating liquid by said ribs.
