The invention relates to a machine for treating containers (12) which are equipped with a neck (14). The inventive machine comprises at least one treatment station having a nozzle (22) which is provided with gripping means (26) for seizing a container (12).The aforementioned gripping means (26) consist of a tubular support sleeve (50) comprising a series of radial holes (52) which are each intended to receive a ball (54) that can move radially between an inner gripping position and an outer release position. The invention is characterised in that the gripping means (26) comprise a tubular control sleeve (56) which is mounted such as to slide between a locked position, in which a truncated-cone-shaped face (58) co-operates with the balls (54) in order to move same towards the gripping position thereof, and an axial unlocked position. The invention is further characterised in that the nozzle (22) comprises controlled drive means (62) which can cause the control sleeve (56) to slide. |
