In this case, the bottom bevel support part 225 has a taper in the region of the bottom undercut part 24, which widens toward the top support part 21 at an angle α to the vertical. The lower bottom bevel support member 225 is coupled to the lower vertical support member 224, and the lower vertical support member 224 in turn is coupled to the lower bevel support member 223 at an angle β, collapsing the upper cavity 23. The inner wall of the bottom bevel support member 225 is at an angle gamma to the inner wall of the bottom horizontal support member 25.
