摘要

The bottle (2) comprises a wall and an anti-filling device (20) extending into the bottle neck (6). This device allows the bottle to be emptied of liquid but prevents its filling. The wall has a thin zone (14) able to form an initial wall rupture section. The anti-filling device comprises a peripheral sheath (22), a central cage (24) and a ball (39) held in a housing and resting under gravity on a seat (38).
