Bottle-shaped containers of biaxially-oriented blow-molded plastic material are introduced into the space formed between the helical blade continuously rotated and the backup plate of a screw conveyor, and are conveyed in one direction to next conveyor by the rotation of the helical blade of the screw conveyor. The bottle-shaped containers are stood by at the end of the conveyor. When the bottle-shaped containers thus conveyed are aligned in predetermined longitudinal and lateral arrary in predetermined number to be stood by, they are simultaneously held by the bottle-shaped container group holding mechanism utilizing negative pressure, and are then raised from the standby position. The bottle-shaped containers thus raised are lowered directly above the corrugated fiberboard box out of the conveyor to automatically accommodate the bottle-shaped container group thus aligned within the corrugated fiberboard by releasing the holding of the bottle-shaped containers by the bottle-shaped container group holding mechanism. The suction tubes of the bottle-shaped container group holding mechanism are mounted longitudinally and laterally at an equal interval in the bottle-shaped containers group holding mechanism to attract the bottle-shaped containers as they are aligned and to release them directly above the packaging bench thereby to accommodate and package them in the corrugated fiberboard box.
