PROBLEM TO BE SOLVED: To have sufficient compression by a first pressing roller and to compress a can container by two sets of a pair of pressing rollers mutually approaching. SOLUTION: A device consists of a pair of first pressing rollers 1, in which plural projecting lines 11, 11 are arranged in the peripheral direction in parallel and are synchronously reverse-driven, and a pair of second pressing rollers 2, in which ruggedness is continuously arranged to the outer peripheral face arranged in parallel thereunder and are synchronously reverse-driven, A can container W is sent into the second pressing rollers 2 from the first pressing rollers 1 and is discharged from the second pressing rollers 2, a relative position of a pair of the first pressing rollers 1 is so that at the state one projecting line 11 is facing/protruding, the mutual projecting lines 11, 11 adjacent at the upper side of rotation direction for the projecting line are arranged at the interval to allow charging of the can container W in parallel, the projecting line is set to a degree so that its tip part presses a can body part of the can container W from both sides.
