1 to 4, the bag mouth buckle of the container bag of the present invention includes: a first buckle 10 in a horseshoe shape (or U shape) and a second buckle 20 in a rod shape.

The first buckle 10 includes an arc-shaped body 11 and two buckle feet 12 integrally formed on both ends of the body 11 . The main body 11 and the two buckle feet 12 form a constricting space 14 with an opening. The main body 11 can be divided into an inner arc side 111 and an outer arc side 113 , and the inner arc side 111 is formed with several convex points 112 . The central part of the main body 11 is provided with a cutout 15 to reduce the thickness of the structure. Preferably, the cutout 15 continues to the outer arc side 113 . The main body 11 is provided with several mechanical workpiece clamping positions 16 . In the illustrated example, the clamping position 16 is a hole penetrating the structural thickness of the main body 11 .

The inner side surfaces 122 of the two buckle feet 12 are flat, but not limited thereto, and may also be tooth surfaces. The open ends 121 of the two buckle feet 12 are configured to be tapered. The outer sides 123 of the two buckle feet 12 are respectively provided with a plurality of buckle teeth 13 , a tooth slot 134 is formed between two adjacent buckle teeth 13 , and each buckle tooth 13 includes an oblique tooth surface 131 and a flat tooth surface 132, the two intersect to form a rounded tooth top 133.

The surface of the second fastener 20 facing the first fastener 10 is defined as the inner side surface 21 , and the surface different from the inner side surface 21 is defined as the outer side surface 22 . The inner side surface 21 is provided with an arc-shaped concave portion 211 . The central portion of the second buckle 20 is provided with a cutout 23 to reduce the structural thickness. Preferably, the cutout 23 continues to the outer side surface 22 .

The second buckle 20 is respectively provided with a through opening 24 at both ends thereof, each through opening 24 includes a first inner side wall 241 and a second inner side wall 242 , the first inner side wall 241 and the second inner side wall 242 242 constitute a width W1 of a through opening, the width W1 of the through opening is greater than a maximum width W2 of the buckle foot 12, the relative distance D1 of the second inner side walls 242 is equal to the relative distance D2 of the two opposite tooth tops 133; A limit tooth 25 is provided on the second inner side wall 242 of the through opening 24 . The limit tooth 25 includes an intersecting helical tooth surface 251 and a flat tooth surface 252 , and the helical tooth surface 251 faces the first buckle 10 . The buckle foot 12. The second buckle 20 has a plurality of mechanical workpiece clamping positions 26 , in the illustrated example, the clamping position is a hole penetrating the structural thickness of the second buckle 20 .

The mechanical workpiece clamping positions 16 and 26 of the first and second fasteners 10 and 20 are clamped by the linearly reciprocating mechanical workpiece, and the first and second fasteners 10 and 20 are operated to move accordingly. As shown in FIG. 5 to FIG. 8 , after the bag mouth 30 of a bulk bag is roughly closed, it is stuffed into the constricting space 14 of the first buckle 10 , and then the two buckles of the first buckle 10 are The feet 12 are respectively inserted into the two through openings 24 of the second buckle 20 , because the width of the through openings 24 is greater than the maximum width of the buckle feet 12 , and the open ends 121 of the buckle feet 12 are tapered, so the The buckle feet 12 can smoothly enter the through opening 24; furthermore, based on the relative distance D1 formed by the second inner side wall 242 equal to the relative distance D2 between the two tooth crests 133, the two buckle feet 12 enter the two When passing through the opening 24, the tooth top 133 can contact or be very close to the second inner side wall 242, so the helical tooth surface 131 of the locking tooth 13 and the helical tooth surface 251 of the limiting tooth 25 can push each other, so that the first A buckle 10 and the second buckle 20 move relative to each other, and the second buckle 20 reduces the binding space 14 so that the pocket 30 is tightly tightened. The tightened pocket also blocks the first buckle 10 and the second buckle 20 so that they cannot move relative to each other. So far, the flat tooth surface 132 of the latching tooth 13 and the flat tooth surface 252 of the limiting tooth 25 block each other, so that the first buckle 10 and the second buckle 20 cannot move in the opposite direction and disengage. The pocket 30 is limited between the first buckle 10 and the second buckle 20, the inner arc side 111 of the first buckle 10 and the recess 211 of the second buckle 20 make the tightening contour of the pocket 30 Can tend to be cylindrical, several convex points 112 on the inner arc side 111 increase the pair of pocket openings of the first buckle 10 30's of cinch grip.

Please refer to FIG. 8 , when the first buckle 10 and the second buckle 20 are snap-fitted to each other, there is a retraction between the inner side 122 of the buckle foot 12 and the first inner side wall 241 of the through opening 24 The distance D3, the retracting distance D3 is used to release the first buckle 10 and the second buckle 20 .

When taking out the items in the container bag, it is necessary to release the buckle relationship between the first buckle 10 and the second buckle 20. The way of releasing can be as shown in Figure 9. Manually operate the double force scissors (not shown in the figure) , cut the first buckle 10 from the cutting opening 15, so that the relative distance and position of the two buckle feet 12 are no longer restricted by the body 11, and the two buckle feet 12 are in a free state respectively. Retracting distance D3, so that the buckle teeth 13 can be separated from the limit teeth 25, so that the buckle feet 12 can be pulled away from the through opening 24, the first buckle 10 and the second buckle 20 are separated, and the bag mouth of the container bag can be opened.

The way of releasing can also be as shown in FIG. 10, by cutting the second buckle 20 from the cutout 23, so that the second buckle 20 becomes two separate parts, and the second buckle 20 is directly connected to the two buckle feet 12. When the limiting force is lost, the above-mentioned retraction distance D3 is used to enable the buckle teeth 13 to be separated from the limit teeth 25, so that the buckle feet 12 can be pulled away from the through-hole 24, the first buckle 10 and the second buckle 20. Separated, the bag mouth of the container bag can be opened.
