Hereinafter, for the sake of convenience of explanation, the case where the container to be injected into the compression apparatus main body 110 is a PET bottle will be mainly described.

The compression apparatus main body 110 may be installed in a vehicle (not shown) carrying a PET bottle. In addition, the main body 110 of the compression apparatus can be installed in a factory (not shown) for recycling PET bottles. Therefore, the main body 110 of the compression apparatus can be loaded with a PET bottle loaded in the automobile or a PET bottle supplied to the factory.

The compression unit main body 110 may include a guide unit 113 installed therein. The guide part 113 may be installed inside the compression device body 110 at a predetermined angle. The guide portion 113 may be disposed between the inlet 111 and the first compression portion 120. The guide unit 113 can guide the PET bottle inserted through the inlet 111 to the upper portion of the first compression unit 120. Therefore, the PET bottles inserted into the main body 110 of the compression device can be easily moved to the first compression part 120.

The first compression unit 120 may be installed inside the main body 110 of the compression apparatus. The first compression unit 120 may be disposed inside the compression unit body 110 so as to be disposed below the guide unit 113 so as to primarily puncture and compress the PET bottle introduced into the compression unit body 110.

For example, when the fifth rotor 141 is rotated in the clockwise direction by receiving the rotational force from the motor unit, the sixth rotor 142 may be rotated in the counterclockwise direction by receiving the rotational force from the motor unit. Therefore, the PET bottles that have passed through the second compression portion 130 due to the rotating directions of the fifth rotor 141 and the sixth rotor 142 are inserted between the fifth rotor 141 and the sixth rotor 142 .

The third compression unit 140 includes a first elastic member 143 that covers the outer surfaces of the fifth rotor 141 and the sixth rotor 142. The third compression unit 140 includes a second elastic member 144 covering the outer surface of the first elastic member 143.
