Claim Text:
1. A device comprising: a base body; and a resin feed device fitted to the base body to fill the base body with resin; the base body comprising an area not to be filled that is not to be filled by the resin after a filling is completed, the base body comprising an opening at a level of an upper end, the area not to be filled being situated at the upper end of the base body and extending inside the base body; the resin feed device comprising an injection column coinciding with the opening and extending inside the base body so that, during the filling, resin gets into the interior of the base body via the injection column, wherein the injection column extends more deeply inside the base body than the area not to be filled, to a distance configured so that when, during the filling, the resin reaches the injection column, air trapped in the base body is compressed in the area not to be filled until an equilibrium is established between pressure of the air in the area not to be filled and pressure of the resin in the injection column, whereby the filling is stopped automatically, so that the area not to be filled is not filled.
