The implementation principle of the clip chain in the embodiment of the present application is that after the first top leaf 11 and the second top leaf 21 of the clip chain are torn off by the first tear line 44, the distance from the first tear line 44 to the first rib 13 and the second rib 23 is too small, and the fingers are difficult to apply force, so that the clip chain is difficult to be pulled open by the remaining first top leaf 11 and the second top leaf 21. The zipper can be opened conveniently by pressing the position of the first rib 31 and then twisting the zipper open towards the same direction or opposite directions by two fingers on the same side of the zipper.

Referring to fig. 15 and 16, a child-resistant bag differs from the bag of example 1 in that the zipper is different, and a second tear line 45 is provided on the bag body 4 corresponding to the first tear line 44, and the second tear line 45 is a point-broken line. In this embodiment, the spot-cutting knife simultaneously forms the first tear line 44 and the second tear line 45 by spot-cutting through the bag 4, the first blade 1, and the second blade 2. Through the cooperation of second tear line 45 and first tear line 44, after tearing first tear line 44 and second tear line 45, the distance of bag body 4 oral area distance first bone strip 13 and second bone strip 23 is shorter to make the difficult bag body 4 of opening from the sack of children. Need pinch the position that lies in setting up bellying 3 on the bag body 4 through both hands, lie in bag body 4 with two fingers orientation syntropy or displacement in opposite directions of one side, can rub the clamp chain open, open bag body 4 then.

Referring to fig. 15 and 16, a method of opening a bag includes the steps of:

s1: tearing the bag body 4 from the first tear line 44 and the second tear line 45, so that the first upper leaf 11 and the second upper leaf 21 are separated from the first tear line 44, and the bag body 4 is separated from the second tear line 45;

s2: the bag body 4 is positioned in the areas of the first bone strips 13 and the second bone strips 23 by being pinched by two hands, and the lug boss 3 is pressed against fingers through the bag body 4;

s3: the two hands twist the bag body 4 towards the same direction or opposite directions, and the first bone strips 13 and the second bone strips 23 are staggered;

s4: the mouth of the bag body 4 is pulled away from the position of the dislocation of the first bone strip 13 and the second bone strip 23.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
