The second molded body has a second principal surface which is generally rectangular and overlies the first principal surface, and a second upstanding wall connected to the first upstanding wall to form the peripheral surface of the half therewith, forming an integral part of the second principal surface and surrounding it. The first and second upstanding walls are connected by a junction having a thickness increasing gradually across the thickness of the half.
