[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] like Figures 1 to 6As shown, a piercing type one-piece bottle cap comprises a bottom cover 10, an upper cover 20 and a piercing portion 30, wherein the bottom cover 10 is fixed on the bottle body, and an outer thread 11 and an inner thread 12 are respectively arranged on the outer wall and the inner wall of the bottom cover 10, and the piercing portion 30 comprises an annular member 31 and a thorn 32 arranged at the lower end of the annular member 31, and the thorn 32 is used to pierce the sealing film on the bottle body and then cut and tear, a stopper 33 is arranged on the inner wall of the annular member 31, and a guide rib 34 is arranged on the outer wall, and the guide rib 34 is screwed on the inner thread 12, and the upper cover 20 comprises an anti-theft ring 21 and a cover The cover body 22 and the anti-theft ring 21 are rotatably arranged at the lower part of the bottom cover 10. A push plate 23 is arranged in the cover body 22, and a notch 200 is arranged on one side. A pair of telescopic parts 24 for connecting with the anti-theft ring 21 are arranged at the lower end of the notch 200. An inverted L-shaped plate 251 and an L-shaped plate 252 are respectively arranged on the anti-theft ring 21 and the cover body 22. The inverted L-shaped plate 251 and the L-shaped plate 252 are arranged left and right between the pair of telescopic parts 24 and are in a buckled shape. The cover body 22 is screwed on the external thread 11, and the push plate 23 is driven to abut against the stopper 33 when the cover body 22 rotates.

[0029] In the present invention, in the unused state, the puncturing part 30 is screwed to the internal thread 12 on the bottom cover 10 through its guiding rib 34, and the upper end of the puncturing part 30 is located at the upper part of the bottom cover 10, and its puncturing tip 32 is located above the sealing film of the bottle body. The upper cover 20 is sleeved on the bottom cover 10, its anti-theft ring 21 is located at the lower part of the outer wall of the bottom cover 10, and its cover body 22 is screwed to the external thread 11 of the bottom cover 10, and the push plate 23 abuts against the stop block 33 after extending into the relative inner side of the annular part 31. When it is necessary to open the puncturing type integral bottle cap, rotate the cover body 22. Due to the screwing effect, the cover body 22 moves upward synchronously when rotating. The connecting effect of the telescopic member 24 enables the telescopic member 24 to be stretched and then the cover body 22 moves upward and is still connected to the anti-theft ring 21. And due to the connecting effect of the telescopic member 24 and the driving effect of the abutting structure 25 composed of the inverted L-shaped plate 251 and the L-shaped plate 252, the anti-theft ring 21 can rotate synchronously. During the process of the cover body 22 rotating and moving upward, its push plate 23 abuts against the stop block 33 on the puncturing part 30 and drives the annular part 31 and the puncturing tip located at the lower end of the annular part 31 to rotate and move downward through the stop block. The puncturing tip 31 can cut and tear the sealing film on the bottle body during the downward movement. Therefore, when the upper cover 20 is rotated to move upward and separated from the bottom cover 10, the puncturing part 30 can be driven to move downward to cut and tear the sealing film so as to open the bottle body. Further, after the cover body 22 moves upward and separates from the bottom cover 10, it is still connected to the anti-theft ring 21 through the telescopic member 24. When the cover body 22 is flipped by a certain angle, the L-shaped plate 252 thereon is also flipped. For example, after being flipped by 90°, the cover body 22 can be offset by a certain distance so that the end of the L-shaped plate 252 far from the cover body 22 abuts against the side wall of the inverted L-shaped plate 251. Through the frictional effect when the two abut against each other and the rebound pulling effect generated by the stretching of the telescopic member 24, the L-shaped plate 252 and the inverted L-shaped plate 251 can be fixed to ensure the stability of the cover body 22. Further still, when the cover body 22 is continuously flipped to 180° with respect to its initial state, the cover body 22 and the L-shaped plate 252 are in an inverted state. Similarly, by offsetting the cover body 22 by a certain distance, the side wall of the L-shaped plate 252 abuts against the side walls of the anti-theft ring 21 and the inverted L-shaped plate 251. Through the above-mentioned abutting and limiting with a larger area, the L-shaped plate 252 is not easy to flip in the reverse direction, thus ensuring the stability of the cover body 22 after flipping.When it is necessary to re-close the cover body 22 on the bottom cover 10, the telescopic piece 24 is stretched, and the cover body 22 and the L-shaped plate 252 are reversed and then snapped onto the bottom cover 10, and then the cover body 22 is rotated to lock it on the bottom cover 10 through the screw connection. In this process, the anti-theft ring 21 can rotate synchronously through the connecting action of the telescopic piece 24 and the driving action of the abutment structure 25, and the telescopic piece 24 finally returns to its original state. It should be noted that, during the process of re-screwing the cover body 22 to the bottom cover 10, since the upper end of the puncture portion 30 is already located at the bottom position of the bottom cover 10, the push plate 23 cannot interact with the stopper 33 of the puncture portion 30, and the puncture portion 30 is still located at the bottom position of the bottom cover 10.

[0030] After the cover body 22 is flipped, the abutment structure 25 can achieve different flipping angles of the cover body 22 by abutting against the inverted L-shaped plate 251 and the L-shaped plate 252 at different positions. It can also enable the anti-theft ring 21 to rotate synchronously with the cover body 22 through the lateral abutment between the inverted L-shaped plate 251 and the L-shaped plate 252 in the initial stage of the cover body 22 rotating to open the bottle body and the final stage of the cover body 22 being locked to the bottom cover 10, thereby avoiding the anti-theft ring 21 being pulled only by the telescopic part 24, avoiding the telescopic part 24 from being stretched for a long time or for a long length, and improving the service life of the telescopic part 24.

[0031] The inverted L-shaped plate 251 and the L-shaped plate 252 of the present invention both have an L-shaped structure and are in a buckled shape, so that the entire abutment structure 25 can have a smaller width, saving injection molding materials, but at the same time can have a larger abutment area and position after flipping (the horizontal plate length of the inverted L-shaped plate 251 and the L-shaped plate 252), ensuring the stability of the abutment.

[0032] Furthermore, a guiding slope is provided on at least one of the side walls of the inverted L-shaped plate 251 and the L-shaped plate 252 close to each other. For example, if a guiding slope is provided on the inverted L-shaped plate 251, the L-shaped plate 252 can utilize the guiding slope to relatively easily pass over the inverted L-shaped plate 251 upward during the movement of the cover body 22 relative to the bottom cover 10, thereby avoiding interference between the two and causing the cover body 22 to be unable to continue to move upward.

[0033] Preferably, the telescopic member 24 includes a connecting piece 241, a transverse rib 242 and a connecting rib 243 which are connected in sequence, the connecting piece 241 is connected to the cover body 22, the connecting rib 243 is connected to the anti-theft ring 10, and a clearance hole 240 is formed between the connecting rib 242 body, or the connecting rib 243 and the anti-theft ring 10. Preferably, a clearance hole 240 is formed between the connecting rib 242 and the anti-theft ring 10. The existence of the clearance hole 240 can make the connecting rib 242 form two branches, and combined with the existence of the clearance hole 240, it provides stretching and torsion space for the branches, thereby realizing the elongation action.

[0034] Furthermore, a protrusion 2421 extending into the clearance hole 240 is provided on one side of the transverse rib 242 close to the connecting rib 243 . The protrusion 2421 can abut against the branch to limit its position after the branch is stretched and twisted to a certain extent, thereby preventing the connecting rib 243 from being overstretched and twisted.

[0035] Preferably, a plurality of limiting protrusions 26 are provided on the inner wall of the anti-theft ring 21 , a limiting ring 15 is provided on the lower part of the outer wall of the bottom cover 10 , and the limiting protrusions 26 are located below the limiting ring 15 , which can prevent the limiting ring 21 from detaching from the bottom cover 10 .

[0036] Moreover, a plurality of bridges 27 for connecting the upper end of the anti-theft ring 21 and the lower end of the cover body 22 are provided between the two. The bridges 27 can initially realize a fixed connection between the anti-theft ring 21 and the cover body 22, and the cover body 22 can be broken during the process of rotating and moving upward on the bottom cover 10 to realize the continued upward movement of the cover body 22.

[0037] In addition, the cover body 22 is provided with anti-slip grooves 221, and parallel abutment surfaces 222 are provided on opposite sides of the cover body 22. The existence of the abutment surfaces 222 makes it easier for the cover body 22 to be embedded in the base of the human hand and to form a larger contact area with the fingers, which is more ergonomic and convenient for exerting force to rotate the cover body 22, especially in the initial stage of rotating the cover body 22 to open the bottle body.

[0038] In one embodiment of the present invention, the guide rib 34 includes two main ribs 341, which are arranged on the annular member 31 with a gap therebetween. A bend 3411 is provided on one side of the main rib 341. The internal thread 12 is intermittently arranged and at least partially forms an inclined portion. The main rib 341 cooperates with the internal thread 12. When the bend 3411 moves to the position of the inclined portion, the downward pressure of the bend 3411 by the inclined portion can make the puncture portion 30 move downward more forcefully to achieve cutting and tearing of the sealing film, thereby improving the processing efficiency of the sealing film.

[0039] In addition, an auxiliary rib 342 is provided on the outer wall of the annular member 31, and the auxiliary rib 342 is connected to one end of the main rib 341 away from the bent portion 3411, and a positioning groove 340 is formed between the auxiliary rib 342 and the upper end of the main rib 31. The upper end of the inner wall of the bottom cover 10 is provided with an upper boss 131 that can match the positioning groove 340, which can ensure the stability of the puncture portion 30 when it is located at the initial position in the bottom cover 10. Similarly, the lower end of the inner wall of the bottom cover 10 is provided with a lower boss 132 that can match the positioning groove 340, which can ensure the stability of the puncture portion 30 when it is located at the final position in the bottom cover 10, that is, the stability after the film sealing process is completed, to prevent it from moving downward and falling into the bottle body.

[0040] A pair of outer edges 35 are provided at the upper end of the ring member 31, and a clearance opening 350 is formed between the pair of outer edges 35. The outer edges 35 can cooperate with the support ribs 14 on the inner wall of the bottom cover 10 to ensure the stability of the ring member 31 during relative rotation. The support ribs 14 can have multiple layers, and through cooperation with the intermittent internal threads 12, the ring member 31 can achieve stable movement in each layer and convenient entry into the next layer.

[0041] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
