PURPOSE: To compress and reduce a can-like body at a high volume reducion ratio and to make the storage thereof easy, by depressing in the cylindrical part of the can-like body in a hollow groove shape, and pressing the same further to form the can-like body to a semicircular sectional shape then compressing the can-like body longitudinally to a flat shape.
CONSTITUTION: A used drum can 2 is pressed by means of a side piston 14 and a side cylinder 11 until the can contacts with the arc surface 4 in the U-shaped notch part of a cylinder body 1 and further a connecting member 16 is advanced until a regulating member 17 contacts with the outside end face 10a of the cylinder 11, then a recessed part 20 like a hollow groove of a prescribed width is formed longitudinally to the can 2 by the piston body 15 of the piston 14. After the piston body 15 is retreated, the cylinder 11 is operated to force the recessed surface part 21 of the can 2 to form the can 2 into a semi-circular shape in cross section. The piston 18 is advanced to compress the can 2 between the same and a cylinder cap 9 to a flat shape, and the can is discharged with a removing plate 19 to the outside of the chamber 13.
