摘要：
A bottom (2) of a hollow body obtained by blowing or stretch-blowing a preform of a thermoplastic material. The bottom (2) includes a transverse support surface (4) and, on either side of the transverse support surface (4), a transverse outer edge (5) and a concave inner wall with a transverse central portion (10) having a pellet (11) of a low-crystallinity material. The pellet corresponds to the injection point of the perform. The bottom (2) has reinforcing ribs (1) having an outer edge (12) adjacent to the outer edge (5) of the bottom (2) as well as an inner edge (13) adjacent to the transverse central portion (10) but not reaching the transverse central portion (10). The reinforcing ribs (1) flare from their outer edge (12) toward their inner edge (13).
