Further, when the bottle cap needs to be opened normally, the second breaking part body 431 can be opened anticlockwise through the gap between the second breaking part body 431 and the lower cover outer ring 102, when the second breaking part body 431 is stressed greatly, the fifth breaking connection part 432 is broken under stress, at this time, after the second breaking part body 431 is opened at a certain angle, the bottom end of the tin plate cover 3 can be leaked out from the position of the open slot 107, and at this time, the whole tin plate cover 3 and the upper cover body 2 can be opened normally at the position of the open slot 107, thereby opening the bottle cap.
Further, when the gap between the tin plate cover 3 and the lower cover body 1 is pried by an external force, the fifth fracture connection portion 432 is easily stressed to be subjected to plastic stretching or direct fracture, and meanwhile, the tin plate cover 3 is difficult to prize at the gap between the outer bulge portion 302 and the inner clamping groove 106 due to the clamping of the outer bulge portion and the inner clamping groove, and an obvious mark is left once the tin plate cover is pried forcibly, so that a good anti-counterfeiting effect is achieved.
Further, the thickness and the height of the second breaking part body 431 are the same as those of the outer ring 102 of the lower cover, and the overall thickness and the height of the second breaking part body 431 are the same as those of the outer ring 102 of the lower cover, so that the whole bottle cap has better aesthetic property, and meanwhile, the bottle cap cannot be easily opened due to external force due to no special protruding part.
Working principle: in the assembly process, the bottle mouth clamping part 103 can be sleeved at the bottle mouth position, and then the bottle mouth clamping part 103 is pressed downwards by force, so that the bottle mouth clamping part 103 rapidly penetrates through the annular protruding part of the packaging bottle mouth and is sleeved at the neck position of the packaging bottle mouth, and as the bottom of the inner side of the bottle mouth clamping part 103 is provided with a plurality of uniformly distributed anti-falling lugs 105, after the bottle mouth clamping part 103 is installed in place, the anti-falling lugs 105 and the annular protruding part of the packaging bottle mouth form a clamping limiting structure, so that the whole lower cover body 1 cannot easily fall off from the packaging bottle mouth;
then, the bottle mouth sealing part 202 of the upper cover body 2 is inserted into the bottle mouth, and is pressed downwards by mechanical equipment or manually, so that the bottle mouth sealing part 202 is completely inserted into the bottle mouth, and at the moment, the outer wall of the bottle mouth sealing part 202 and the inner wall of the bottle mouth are mutually extruded, so that the bottle mouth sealing part 202 can be tightly attached to the inner wall of the bottle mouth after being extruded by the inner wall of the bottle mouth, thereby sealing the bottle mouth, and in the process, the outer convex part 302 is clamped with the inner clamping groove 106;
when the bottle cap needs to be normally opened, the main body part of the anti-counterfeiting damage structure 4 can be broken off or broken off by force, at the moment, the broken connecting part connected with the lower cover body 1 on the anti-counterfeiting damage structure 4 can be broken by force, at the moment, the position of the opening groove 107 can be opened, at the moment, the anti-counterfeiting structure is completely damaged and can not be recovered, at the position of the opening groove 107, the bottom end of the tinplate cover 3 can be leaked, at the moment, the whole tinplate cover 3 and the upper cover body 2 can be buckled from the bottom of the tinplate cover 3, the lower cover body 1 can be normally left on a packaging bottle opening, and at the moment, the content in the packaging bottle can be normally poured out.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention.
