Reference numeral 16 denotes a rectangular thin box having an elongated outlet 16a formed at the center of the upper surface 16U, and a bag 18 (referred to as a polybag) formed of polyethylene resin is folded and stored inside the box. . As is well known in the art, the folding structure of the plastic bag 18 is such that, when one plastic bag 18 is removed through the outlet 16a, the upper end of the next plastic bag 18 is connected to the outlet 16a.
The plastic bag 18 can be continuously extracted.

In addition, at the four corners of the upper surface 16U of the plastic bag box 16, supply / exhaust holes 16b,
…, 16b are drilled and two predetermined side faces facing each other
A supply / exhaust hole 16c is formed in the center of each of 16S and 16S, and a filter is attached to the supply / exhaust hole 16c.

The four side surfaces 16S,..., 16S of the plastic bag box 16 are also provided with hooking mechanisms 20, respectively.
As shown in FIG. 2, reference numeral 20 denotes a grooved rail 20a, and a locking plate 20c supported on the rail 20a by a spring 20b.
It is composed of At the center of the locking plate 20c, a projection is formed along the longitudinal direction. On the other hand, hook grooves 14a capable of engaging with the engaging plates 20c of the respective hook mechanisms 20 are formed at the four corners on the bottom side of the dust receiving cylinder 14, respectively. Of the hooking grooves 14a, the one on the side of the supply / exhaust hole 16c is integrally formed as a supply / exhaust groove. In addition, an edge which fills a gap with the plastic bag box 16 is provided around the inner bottom portion of the waste receiving cylinder 14.

Next, the operation and effect of the waste receiving apparatus 12 according to the present embodiment, including how to use the same, will be described.

First, the waste receiving cylinder 14 is placed on the plastic bag box 16 from above as indicated by the imaginary line A in FIG. At this time, the waste receiving cylinder 14 is lowered until the lower end of the wall thereof pushes the locking plate 20c of the hooking mechanism 20 inward against the spring 20b, and the projection of the locking plate 20c is formed in the hooking groove 14a of the cylinder 14. The part is fitted by spring force. As a result, the plastic bag box 16 is fixed to the inner lower end of the waste receiving cylinder 14, and the upper surface 16U of the plastic bag box 16 forms the bottom surface of the cylinder 14, so that a box is formed as a whole.

Next, one plastic bag 18 is taken out from the outlet 16a located on the inner bottom surface of the box. As a result, the next plastic bag 18 appears at the outlet 16a, and preparation for the next plastic bag replacement is made. On the other hand, the plastic bag 18 taken out is lifted while being spread as it is, and the upper end thereof is hooked on the edge of the upper end of the waste container 14 as shown in FIG. Then, the air between the plastic bag 18 and the cylindrical body 14 and the plastic bag box 16 is discharged through supply / exhaust holes 16b,..., 16b and 16c, 16c on the bottom surface as shown by the dotted line in FIG. As a result, the swelling of the plastic bag 18 due to the positive pressure state is easily removed, and the plastic bag 18 is fully spread inside the box as shown in FIG. 3, so that the maximum internal volume can be secured.

The waste receiving device 12 set in this way is stored on the shredded waste discharge side of the document shredder 10, as shown in FIG. When the paper waste is full, the mouth of the plastic bag 18 is tied up and pulled up for disposal. At this time, since the outside air flows in through the air supply / exhaust holes 16c, 16c and 16b,..., 16b as shown by the dotted line in FIG. Is easily released, and the force required to pull up the plastic bag 18 is reduced. This solves the conventional problem that it is difficult to pull up the plastic bag 18.
