的とするものである。Needless to say, it is effective to bring a used can into a resource treatment facility or the like in a state of being crushed and flattened to eliminate bulk. However, since the can is shaped by tightly winding the can body around the can bottom, it cannot be crushed and flattened easily. Therefore, the can is brought to the resource processing facility without crushing. Therefore, it is necessary to secure an enormous amount of deposition space for the processing equipment. In view of such circumstances, an object of the present invention is to add a device to a structure for winding a can body and a can bottom so that the can can be easily crushed and flattened.

めたことを要旨とする。The present invention for achieving the above object provides a can of a type in which the peripheral edge of a can body and the peripheral edge of a can bottom are tightly wound inward through a packing. The gist is that the peripheral edge is formed by a large number of winding fastening pieces divided through notches, and the winding fastening pieces are independently wound around the peripheral edge of the can body.

構成されている。DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a bottom view of a can bottom A. As can be seen from the perspective view of FIG. 2, the can bottom A has a circular flat plate portion 1, a rib 2 having a semicircular arc cross section on the outer periphery thereof, and a peripheral edge 3 hanging downward from the outer end of the rib 2. It is composed of a packing 4 (elastic sealing material) fitted in an inner groove forming the rib 2.

が常法の手段を用いて行われることは勿論である。Therefore, the gist of the present invention is that the can bottom A is
The peripheral edge 3 is formed as follows. That is, cuts 5 having a required width and a required depth are provided on the peripheral edge 3 of the can bottom A at equal intervals.
A large number of winding fastening pieces 6 each of which is divided by the notches 5 are formed at equal intervals, and the winding fastening pieces 6 are independently wound around the peripheral edge 7 of the can body B as shown in FIGS. It has been wrapped around. The shapes of the notch 5 and the winding fastening piece 6 may be selected as appropriate, and the winding is of course performed by a conventional method, although not particularly shown.

っていることは勿論である。FIG. 3 shows a cross-sectional view of the cut 5 portion. Therefore, the winding amount of the cut 5 portion with respect to the peripheral edge 7 of the can body B is small as shown in the figure, and the tightening force is almost working. Absent. On the other hand, FIG. 4 is a sectional view of the winding fastening piece 6 at the position,
Therefore, the winding amount of the fastening piece 6 with respect to the peripheral edge 7 of the can body B is large, and the fastening force is strong. In addition, packing 4
Needless to say, as shown in FIG. 3, airtightness is maintained by interposing a pressure-bonded portion between the winding portions of the can body B and the can bottom A so as to close the deep portion of the notch 5.

れにより缶底Ａは缶胴Ｂから離脱される。In the wound can, the can bottom A side is faced up, the can is erected and grounded, and in this state, the arrow C portion of the flat plate portion 1 is sequentially tapped in the circular direction. Since the respective fastening pieces are wound independently, the respective winding fastening pieces 6 are simply extended from the winding-closed state and released, whereby the can bottom A is detached from the can body B.

スペースの有効利用化に大きく寄与することができる。As described above, according to the present invention, the following effects can be obtained. The peripheral edge of the can bottom is formed by a large number of winding fastening pieces that are divided by notches, and the winding fastening pieces are individually wound around the peripheral edge of the can body, so a small tapping force is applied to the bottom surface of the can. The can bottom can be easily detached from the can body by simply releasing the winding state of the can bottom from the can body. Also, once the can bottom is removed, the can body can be flattened by crushing the can body from the peripheral side with a foot or the like, which makes the work extremely easy. At the same time, it can greatly contribute to the effective utilization of the deposition space such as resource processing equipment.
