US Patent 7144181 Joining device and kitchen appliance fitted with the joining device

A joining device joins first and second bodies. The joining is simple and can be well-maintained, between a first and a second body that are, for example, parts of a food processor, whereby the first wall forms the bottom and the second wall is an outer wall. The first wall of the first body extends substantially at a right angle to the second wall of the second body. A detent projection, which is placed on an inner side of the first wall that is encircled by the second body, is pushed into a detent opening inside the wall by the force exerted by a connection device, particularly a screw, that is joined to the first body.
