ABSTRACT:
A rotating force vector is applied to the sidewall of a can at a sufficient distance removed from the end of that can to permit the easy distortion of that sidewall and the ready rotation of the can-end toward a plane which lies essentially parallel to the cylindrical axis of the can. Means are provided to further distort the can and, through the second application of a rotating force vector, to rotate the second end of the can into a plane essentially parallel with the cylindrical axis of the can. Flattening means applied to the can after each revolution of a can-end tends to bring the planes into which the can-ends lie into close juxtaposition so as to provide a relatively flat package requiring comparatively little storage space when compared to the amount of space required to store the original undistorted can.
