The support members 11 and 12 are swingably supported around a support shaft 13 from the center toward the tip. Further, the rear ends of the support members 11 and 12 are configured as grip portions 11a and 12a, respectively.

[0014] As shown in FIG.
A hexagonal prism-shaped main body 21; a cutting blade 22 extending tapered from a lower end of the main body 21 and extending in a lateral direction with respect to a longitudinal direction (longitudinal direction) of the first support member 11; And a relief groove 23 extending in the vertical direction. In addition, it is preferable that the whole body 21 is formed to be curved about the support shaft 13 as a whole.

As shown in FIG.
The punch 20 has a hexagonal column-shaped concave portion 31 corresponding to the hexagonal column-shaped main body 21.
Is opened by a notch 32 in the longitudinal direction (longitudinal direction) of the second support member 12. This recess 31
Also, the support shaft 13 corresponds to the main body 21 of the punch portion 20.
Is preferably formed around the center of the circle.

Thus, when the grip portions 11a and 12a of the first support member 11 and the second support member 12 are closed so as to approach each other, the main body 21 of the punch portion 20 moves to the concave portion 31 of the die portion 30. It fits inside.

As shown in FIG. 2, the biting prevention lever 40 is supported by the first support member 11 so as to be swingable around a rotation shaft 41 closer to the tip than the support shaft 13. As shown in FIG. 3, a hole 42 having a size that allows the main body 21 of the punch portion 20 to pass therethrough is provided at the tip.
Further, the bite prevention lever 40 is urged by a spring 43 in a direction away from the distal end of the support member 11 near an intermediate point between the rotation shaft 41 and the distal end. Incidentally, 44 in the figure
The spring 43 is loosely fitted to the support member 1 more than necessary.
This is a support pin for supporting the member 1 so as not to be separated from it.

The caulking lever 50 is swingably supported on the support shaft 13 as shown in FIGS. Here, the caulking lever 50 is formed so that the dice part 30 can be fitted into a hole 51 provided at the tip thereof, and the notch part 32 of the dice part 30 is formed.
And a pair of projections 52 projecting inward from each other and extending upward. Furthermore, caulking lever 5

These operating arms 11b and 12b are swingably supported by the first support member 11 and the second support member 12, respectively, and are also swingably supported by the support shaft 14. Further, a connecting rod 15 is slidably supported on the support shaft 14. The connecting rod 15 penetrates through the arm 53 and has a large-diameter stopper 15a at the front end and an adjusting nut 15b at the rear end. The adjustment position of the caulking lever 50 is adjusted by adjusting the adjusting nut 15b in a screwing manner, so that the caulking lever 50 corresponds to the material of the container 60.

Accordingly, when the grip portions 11a, 12a of the first support member 11 and the second support member 12 are closed so as to approach each other, each of the operating arms 11b, 12b
The support shaft 14 moves rearward, and pushes the adjustment nut 15b at the rear end of the arm 53 rearward. Therefore, the connecting rod 15
The pulling portion 15a pulls the arm portion 53 backward, so that the caulking lever 50 resists the tension of the spring 54,
In FIG. 4, it is turned clockwise.

The binding device 10 according to the embodiment of the present invention is configured as described above. When the ear portion 61 of the container 60 is bound, the binding is performed as shown in FIGS. First, in FIG. 4, between the tips of the support members 11 and 12 of the binding device 10, the overlapping ear portions 61 of the container 60 to be bound are inserted. In this state, the biting prevention lever 40 is urged inward from the tip of the support member 11 by the tension of the spring 43, and the caulking lever 50 moves inwardly to the tip of the support member 12 by the tension of the spring 54. The die portion 30 protrudes largely inward from the hole 51.

Next, as shown in FIG. 5, the user grips the grip portions 11a and 12a of the support members 11 and 12 against the return spring 16 so that the grip portions 11a and 12a are held.
To each other. Thereby, the support members 11 and 12
Are closed with each other, the punch portion 20 and the die portion 30 approach each other, and the cutting blade 22 of the punch portion 20 cuts the ear portion 61 of the container 60 in the lateral direction to form a cut which is the first cut at the center. A (see FIG. 7B) is formed.

Further, when the support members 11 and 12 are closed, the side edge of the main body 21 of the punch portion 20 and the side edge of the concave portion 31 of the die portion 30 cooperate to sandwich the ear portion 61 of the container 60, and As a result, a cut B (see FIG. 7B), which is a second cut extending vertically and inward on both sides from both ends of the center cut A, is formed. Here, break B
Is substantially hexagonal, corresponding to the hexagonal shape of the main body 21 of the punch portion 20 and the concave portion 31 of the die portion 30. Therefore, the cuts A and B form two substantially hexagonal tongue pieces 61a and 61b. At this time, the sides of the tongue pieces 61a and 61b facing each other in the vertical direction are not cut because the cutout portions 32 are provided in the concave portions 31 of the die portion 30, and are connected to the ear portions 61. .

At this time, the tip of the die portion 30 has a hole 4 of the biting prevention lever 40 against the tension of the spring 43.
The ear part 61 is clamped around the periphery of the second part 2. This allows
The cutting of the ear 61 by the punch 20 and the die 30 is stably performed. The protrusion 52 of the caulking lever 50 passes through the notch 32 of the die portion 30 and protrudes into the recessed portion 31. However, since the escape groove 23 is formed in the punch portion 20, the protrusion 5
2 fits into the escape groove 23, so that the punch 20
Of the die portion 30 into the recessed portion 31 can be smoothly performed. Further, at this time, the operating arms 11b, 12b attached to the support members 11, 12
The support shaft 14 moves rearward and comes into contact with the adjustment nut 15b of the connecting rod 15.

Subsequently, as shown in FIG.
When the levers 1 and 12 are closed, the connecting rod 15 is pulled rearward by the operating arms 11b and 12b, so that the caulking lever 50 turns clockwise in FIG. As a result, the projection 52 of the caulking lever 50 is
Each tongue piece 61a, 61b divided by the zero cutting blade 22
Are pushed up and spread out above the ears 61.
Accordingly, as shown in FIG. 7, the tongue pieces 61a and 61b are particularly pushed by the tongue pieces 61a and 61b of the lower ear part 61 of the container 60 passing through the upper ear part 61 and being pushed upward. Then, the hole formed by the tongue pieces 61a and 61b is caulked in shape, and the ear 61 of the container 60 is closed.

Finally, when the user opens the grips 11b, 12b of the supporting members 11, 12 with the return spring 16, the operating arms 11b, 12b release the connecting rod 15, so that the caulking lever 50 is pulled by the tension of the spring 54. The support member 12 is turned leftward and retracted toward the inside of the tip of the support member 12, and the main body 21 of the punch portion 20 comes out of the concave portion 31 of the die portion 30. At this time, the biting lever 40 turns leftward due to the tension of the spring 43, so that the biting lever 40 pushes the ear 61 of the container 60 downward. Thereby, the ear part 6
1 indicates that the punch portion 20 comes off, the bite of the ear portion 61 against the punch portion 20 is prevented, and the
1, the tongue pieces 61a, 61b
1b is engaged with the cut B of the hole 61c formed by
As shown in FIG. 6A, the container 6 is bent and crimped,
The zero ear 61 can be closed.

Thus, the ears 61 of the container 60 are bound to each other. In this case, instead of using a conventional stapler, cellophane tape, or rubber band,
Since the container can be bound in a closed state, running cost is unnecessary, and when opening the container, the tongue of one ear is elastically deformed and pulled out from the cutout due to the cut of the other ear. Thereby, the container can be easily opened and dust such as staples, cellophane tapes, rubber bands and the like as in the related art is not generated, which is advantageous from the viewpoint of protection of the global environment.
