5b is provided. Further, in this example, since the empty can is crushed by using the suction device, the sealing member 11 is not necessary, and the structure is simplified accordingly.

In the embodiment shown in FIGS. 1 to 8, the engaging pins 19 of the sealing member 11 are attached to the base member 9 respectively.
Although it has been described that the sealing member 11 is attached to the base member 9 by engaging with the notch 23, the sealing member 11 is not limited to this, and the sealing member 11 may be attached to the base member 9 by screwing, etc. Can be adopted. Further, as shown in FIG. 10, when the sealing member 11 is attached to the base member 9, a third member A may be provided to hold them from the outside. Further, in each embodiment, as shown in FIG. 10, for example, a container 9a for storing the liquid in the empty can may be provided in communication with the discharge port.

In each of the above-mentioned embodiments, the can compressor applicable to both the small empty can 3 and the large empty can 5 has been described. However, in order to crush either the small empty can 3 or the large empty can 5. It goes without saying that the present invention may be implemented as a dedicated compressor of

[0053]

As described above, according to the present invention,
The empty can installed on the base member is made to have a negative pressure by a suction device, or the empty can is crushed by supplying the compressed fluid into the closed container by the pressure of the compressed fluid. Crushing work becomes unnecessary, and the conventional press mechanism and actuators for driving this are not required. As a result, the device can be simplified without increasing the size of the device, and the cost is low. This type of can compressor can be realized at a cost.
