A container forming device comprises a container conveyor 21 having a plurality of holders 34 and intermittently drivable so as to halt the holders 34 at an ear bonding station S3 in succession, an upper ear pressing member 61 disposed above the ear bonding station S3 so as to be movable upward or downward for pressing upper ears U1 against an upper wall of a container body M1, and a pair of lower ear pressing members 62 arranged at opposite sides of the ear bonding station S3 so as to be openable or closable for pressing lower ears L1 against respective side walls of the container body M1. Each of the holders 34 comprises a bottom plate 51 extending in parallel to a container transport path, and a side plate 52 projecting upward from the bottom plate 51 and extending orthogonal to the container transport path. The bottom plates 51 of each pair of adjacent holders 34 are adapted to place the container body M1 thereon, with the side plates 52 of the adjacent holders 34 holding the container body Ml therebetween. The device further comprises lock members 91 for locking the side plates 52 of the adjacent holders 34 so as not to permit upper ends of the side plates to move away from each other when the upper ear pressing member 61 and the lower ear pressing members 62 press the ears U1, L1 against the container body M1.
