A container gripper (1) is provided with an ascending/descending container platform (3) capable of supporting a bottom surface of a container held in grippers (6, 8). A gripping part of the first gripper (8) is provided with gripping pieces (8a, 8b) which have a gripping shape adapted to a neck part provided to a head part, and which grip at least half of the circumference of the neck part. A gripping part of the second gripper (6) is provided with gripping pieces (6a, 6b) which are adapted to a lower part of the neck part, and which grip at least half of the circumference of the lower part. When a bottle-shaped can (B) is being held, the gripping pieces (6a, 6b) grip the lower part of the neck part, and a bottom surface of the bottle-shaped can is supported by the container platform (3). When a polyethylene terephthalate (PET) bottle (P) is being held, the gripping pieces (6a, 6b) come into contact with the underside of a neck ring of the PET bottle, and grip the lower part of the neck part, and the container platform (3) is withdrawn to a position in which no contact is made with a bottom surface of the PET bottle. The container gripper (1) can be used to grip both bottle-shaped cans (B) and PET bottles (P). |
