The holder has a device, operated by the weight of the cup etc., to fix the cup in the holder. The device is e.g. a net-like bag (5), which decreases in size when under load. It has a ring-shaped element (3,6) at the top and the bottom, with the lower ring being smaller than the upper one. The bag may be of elastic material, and has a rubber-coated interior. The holder is pivoted about an eccentric fastening point, and the device is a clamp element, acting with a fixed counter part.
