To provide a compressively processing apparatus of an empty vessel with which, in the case of an empty resin vessel, especially a mouthpiece of this empty resin vessel, for example, in the state where the vessel is hermetically sealed with the cap is also surely compressed and the stability of the empty resin vessel after compressive processing is suppressed and also, in the case of an empty can, a motor is miniaturized and the manufacturing cost or the like is suppressed by crushing the side end part of the empty can and evading crushing of the can end parts and also the empty cans are easily gathered into a lump shape because they are engaged with each other when pressing the recovered empty cans into a block shape later.

A compressing roller R is constituted by supporting a plurality of plate-like roller elements Rp made of a material having strength equivalent to steel with a rotary shaft. A compressing roller R which is oppositely arranged has a pressing part P, an receiving part C for receiving the end part of the empty vessel fed from above and a hook part F for guiding the empty vessel in the progressing direction of processing.
