Body of a fuel cap unit fitted to the fuel pipe, and its production processes

Body (1) of a fuel cap unit, where this body (1) is an element similar in shape to a basin, to which the fuel cap is connected and which is provided with a hard part (3) optionally finished in a crown (9) of soft material, and a soft part (4), with the peculiarity that the soft part (4) ends in its lowest or closest section to the fuel pipe with a hard base (5), optionally connected to the hard part (4) by means of hard material bridges (2). The connection between the fuel pipe and the body (1) is performed in the hard base (5), whilst the absorption of dispersions is performed in the soft part (4) and, if applicable, the bridges (2), improving the performance efficiency of both activities as they are carried out in different sections of the body (1).
