An anti-counterfeiting bottle cap

Abstract

The present invention discloses an anti-counterfeiting bottle cap, belonging to the technical field of bottle caps, which includes a bottle cap body and an anti-theft ring arranged below the bottle cap body. A theft-proof connection module is provided at the bottom end of the bottle cap body. The theft-proof connection module includes connecting bridges, connecting rings and compensation sealing plates. The number of the connecting bridges and the compensation sealing plates is several. In the present invention, the theft-proof connection module stably connects the bottle cap body and the anti-theft ring from the middle area, compensates for the inner shell to bear force inside the anti-theft ring instead of the anti-theft ring, and the force borne by the inner shell is transmitted to the angled elastic member to make the inclined part of the angled elastic member deflect outwards. The vertical plate drives two angled cutting heads to squeeze and cut the edge part of the connecting bridge connecting the bottle cap body and the anti-theft ring from behind the aligned connecting bridges, so that the connecting bridge irreversibly breaks and disengages between the bottle cap body and the anti-theft ring, effectively destroying the integrity of the bottle cap and improving the anti-counterfeiting and anti-theft effect of the bottle cap.

Description

Technical Field

[0001] The present invention relates to the technical field of bottle caps, and particularly relates to an anti-counterfeiting bottle cap. Background Art

[0002] The function of the bottle cap is to seal the bottle. Among them, the plastic bottle cap is a common beverage bottle cap. The main body of the bottle cap is screwed onto the mouth part of the bottle body. The anti-theft ring at the lower part of the combination of the bottle cap main body forms a sealing structure at the mouth part of the bottle. At the same time, after the bottle cap main body is screwed, it breaks off from the anti-theft ring to achieve the effect of anti-counterfeiting and anti-theft. The bottle cap main body and the anti-theft ring are separately connected together through a connecting bridge in the middle part. The position of the anti-theft ring is on the circular support that expands outward at the mouth part of the bottle. There is a certain gap between the bottom of the anti-theft ring and the circular support, so that the bottom of the anti-theft ring is easy to extend into and squeeze the pressing sheet. The pressing sheet moves upward inside the anti-theft ring and rotates around the anti-theft ring to squeeze and expand each area of the anti-theft ring, which easily causes the anti-theft ring to expand to a state where it can move outside the screwing line at the mouth part of the bottle. Thus, without damaging the bottle cap and the anti-theft ring, the bottle cap can be pried open and removed. Only relying on the separate connection of the anti-theft ring and the bottle cap main body at the mouth part of the bottle cannot effectively monitor and adjust the integrity of the connection between the bottle cap main body and the anti-theft ring when the anti-theft ring is squeezed and expanded, thus affecting the anti-counterfeiting and anti-theft effect of the bottle cap and the safe use of the bottle and the bottle cap. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-counterfeiting bottle cap. By setting an anti-theft connection module to stably connect the bottle cap body and the anti-theft ring from the middle area, several compensation sealing plates fill the space between the bottle cap body, the anti-theft ring and the connecting bridge, and block several extrusion cutting modules to prevent several angular cutting heads from being exposed outside. The inner shell makes up for the force on the inner side of the anti-theft ring instead of the anti-theft ring. The force on the inner shell is transmitted to the angular elastic member, causing the inclined part of the angular elastic member to shift outward. The vertical plate drives two angular cutting heads to squeeze and cut the edge part of the connecting bridge connecting the bottle cap body and the anti-theft ring from behind the aligned connecting bridge, so that the connecting bridge irreversibly breaks and disengages between the bottle cap body and the anti-theft ring, effectively destroying the integrity of the bottle cap and improving the anti-counterfeiting and anti-theft effect of the bottle cap, so as to solve the problems raised in the above background art.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] An anti-counterfeiting bottle cap includes a cap body and an anti-theft ring provided below the cap body. The bottom end of the cap body is provided with an anti-theft connection module, and the anti-theft connection module includes connection bridges, a connection ring, and compensation sealing plates. The number of the connection bridges and the compensation sealing plates is several. Several of the connection bridges are fixedly arranged in a ring on the outer side wall of the connection ring and are positioned at the bottom end of the cap body. The anti-theft ring is positioned below the cap body through several of the connection bridges. Several of the compensation sealing plates surround the connection ring to fill the spaced space between the cap body, the anti-theft ring, and the connection bridges. An inner splicing stress-receiving module is arranged inside the anti-theft ring. The inner splicing stress-receiving module includes a supplementary inner shell and an inner retaining ring. The inner retaining ring is clamped and positioned inside the anti-theft connection module through the supplementary inner shell. Several extrusion cutting modules corresponding to the connection bridges respectively are arranged between the anti-theft ring and the inner splicing stress-receiving module. The extrusion cutting module includes an angular elastic member, a vertical plate, and an angular cutting head. The number of the angular cutting heads is two. The two angular cutting heads are positioned above the inclined portion of the angular elastic member through the vertical plate. The inclined portion of the angular elastic member is fixedly connected to the outer side wall of the supplementary inner shell.

[0006] Further, two compensation sealing plates distributed one above the other are arranged between two adjacent connection bridges. The two compensation sealing plates are fixedly connected to the outer side wall of the connection ring, and the two ends of each compensation sealing plate are respectively in contact with the corresponding two connection bridges.

[0007] Further, the inner edge portion of the top of the connection bridge is fixedly connected to the bottom end of the cap body, and the inner edge portion of the bottom of the connection bridge is fixedly connected to the top end of the anti-theft ring.

[0008] Further, a splicing groove is formed at the bottom of the anti-theft ring, and the bottom of the supplementary inner shell is clamped and connected inside the splicing groove.

[0009] Further, the inner retaining ring is fixedly connected to the top of the supplementary inner shell, and the top end of the inner retaining ring is flush with the top end of the anti-theft ring.

[0010] Further, an activity space is formed between the anti-theft ring and the supplementary inner shell, and the extrusion cutting module is located inside the activity space.

[0011] Further, the vertical plate is fixedly connected to the top end of the inclined portion of the angular elastic member. The two angular cutting heads are fixedly connected to the outer side wall of the vertical plate one above the other. The two angular cutting heads are both located behind the corresponding connection bridge, and the tip portions of the angular cutting heads are aligned with the inner edge portions of the connection bridges.

[0012] Further, the outer side wall of the supplementary inner shell has an inclined pushing portion, the inclined portion of the angled elastic member is fixedly connected to the inclined pushing portion, the other side of the angled elastic member is clamped against the inner side wall of the anti-theft ring, and the outer side wall of the inner retaining ring is fixedly connected to the inner side wall of the vertical plate.

[0013] Further, a groove is formed in the outer side wall of the supplementary inner shell, and the groove is located below the inclined pushing portion.

[0014] Further, an inner bottle stopper is fixedly connected inside the bottle cap body, and the outer side wall of the inner bottle stopper is closely attached to the inner wall of the bottle mouth.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In the present invention, the inner splicing force-receiving module is positioned inside the anti-theft ring, and the anti-theft connection module stably connects the bottle cap body and the anti-theft ring from the middle area, so that the tip portions of several angled cutting heads are respectively from the rear of the corresponding connection bridges, aligning the inner edge portions of the connection bridges to splice the bottle cap body and the anti-theft ring. Several compensation sealing plates surround the connecting ring to effectively fill the space between the bottle cap body, the anti-theft ring and the connection bridges, and shield several extrusion cutting modules, so that the bottle cap body, the anti-theft ring, the anti-theft connection module, the inner splicing force-receiving module and the extrusion cutting module are kept in an integral state and fastened to the bottle mouth portion of the bottle body. At the same time, it avoids several angled cutting heads being exposed outside. The supplementary inner shell inside the anti-theft ring can bear force instead of the anti-theft ring. The force on the supplementary inner shell is transmitted to the angled elastic member, causing the inclined portion of the angled elastic member to deflect outward. The vertical plate drives two angled cutting heads to squeeze and cut the edge portions of the connection bridges connecting the bottle cap body and the anti-theft ring from the rear of the aligned connection bridges, so that the connection bridges are irreversibly broken and disengaged between the bottle cap body and the anti-theft ring, effectively destroying the integrity of the bottle cap, and regionally destroying the integrity of the connection between the bottle cap body and the anti-theft ring from the squeezed area, improving the anti-counterfeiting and anti-theft effect of the bottle cap.

Figures 1 to 5 In the detailed description of the structure, it will be clearly presented. The structure content mentioned in the following embodiments is all referenced to the drawings of the specification.

[0025] Please refer to Figures 1 - 5 , in the embodiment of the present invention, an anti-counterfeiting bottle cap includes a bottle cap body 1 and an anti-theft ring 2 arranged below the bottle cap body 1. The bottom end of the bottle cap body 1 is provided with an anti-theft connection module 3. The anti-theft connection module 3 includes a connection bridge 31, a connection ring 32 and a compensation sealing plate 33. The number of connection bridges 31 and compensation sealing plates 33 is several. Several connection bridges 31 are fixedly arranged in a ring on the outer side wall of the connection ring 32 and positioned at the bottom end of the bottle cap body 1. The anti-theft ring 2 is positioned below the bottle cap body 1 through several connection bridges 31. Several compensation sealing plates 33 surround the connection ring 32 to fill the interval space between the bottle cap body 1, the anti-theft ring 2 and the connection bridge 31. An inner splicing force receiving module 4 is arranged inside the anti-theft ring 2. The inner splicing force receiving module 4 includes a supplementary inner shell 41 and an inner retaining ring 42. The inner retaining ring 42 is clamped and positioned inside the anti-theft connection module 3 through the supplementary inner shell 41. Several extrusion cutting modules 5 corresponding to the connection bridges 31 respectively are arranged between the anti-theft ring 2 and the inner splicing force receiving module 4. The extrusion cutting module 5 includes an angular elastic part 51, a vertical plate 52 and an angular cutting head 53. The number of angular cutting heads 53 is two. The two angular cutting heads 53 are positioned above the inclined part of the angular elastic part 51 through the vertical plate 52. The inclined part of the angular elastic part 51 is fixedly connected to the outer side wall of the supplementary inner shell 41.

[0026] The anti-theft ring 2 is vertically arranged below the cap body 1 of the bottle cap. The anti-theft connection module 3 connects the cap body 1 and the anti-theft ring 2 from the middle area between the cap body 1 and the anti-theft ring 2. The anti-theft connection module 3 is composed of connection bridges 31, a connection ring 32 and compensation sealing plates 33. The number of connection bridges 31 and compensation sealing plates 33 is several. The several connection bridges 31 are fixedly connected in a ring shape on the outer side wall of the connection ring 32. The connection ring 32 is located between the cap body 1 and the anti-theft ring 2. The top and bottom of the connection bridge 31 respectively correspond to the bottom end of the cap body 1 and the top end of the anti-theft ring 2. The inner edge part of the top of the connection bridge 31 is fixedly connected to the bottom end of the cap body 1, and the inner edge part of the bottom of the connection bridge 31 is fixedly connected to the top end of the anti-theft ring 2. The cap body 1 and the anti-theft ring 2 are stably and effectively connected through the several connection bridges 31. Two compensation sealing plates 33 are arranged between two adjacent connection bridges 31. The two compensation sealing plates 33 are distributed one above the other. Both of the two compensation sealing plates 33 are fixedly connected to the outer side wall of the connection ring 32, and the compensation sealing plates 33 are stably connected in the spaced space between the connection ring 32 and the connection bridges 31. The two ends of the compensation sealing plate 33 respectively contact the corresponding two connection bridges 31, so that the several compensation sealing plates 33 surround the connection ring 32, and can effectively fill and block the spaced space between the cap body 1, the anti-theft ring 2 and the connection bridges 31, improving the integrity of the bottle cap. An inner bottle mouth plug 11 is fixedly connected inside the cap body 1. The outer side wall of the inner bottle mouth plug 11 is closely attached to the inner wall of the bottle mouth. The inner bottle mouth plug 11 can be plugged into the inside of the bottle mouth during the process of screwing the cap body 1 onto the bottle mouth part, improving the sealing effect of the bottle.

[0027] The internal splicing force receiving module 4 is arranged inside the anti-theft ring 2. The internal splicing force receiving module 4 is composed of a supplementary inner shell 41 and an inner retaining ring 42. A splicing groove 21 is opened at the bottom of the anti-theft ring 2. The bottom of the supplementary inner shell 41 is snap-fitted and connected inside the splicing groove 21. The inner retaining ring 42 is fixedly connected to the top of the supplementary inner shell 41. The top end of the inner retaining ring 42 is flush with the top end of the anti-theft ring 2, stably combining the internal splicing force receiving module 4 inside the anti-theft ring 2, and making the internal splicing force receiving module 4 and the anti-theft ring 2 form an integral anti-theft structure.

[0028] An active space 6 is formed between the anti-theft ring 2 and the supplementary inner shell 41, and a number of extrusion cutting modules 5 are annularly distributed inside the active space 6. The extrusion cutting module 5 is composed of an angular elastic member 51, a vertical plate 52, and an angular cutting head 53. The vertical plate 52 is fixedly connected to the top of the inclined portion of the angular elastic member 51. The number of angular cutting heads 53 is two, and the two angular cutting heads 53 are fixedly connected to the outer side wall of the vertical plate 52, one above the other. The outer side wall of the supplementary inner shell 41 has an inclined pushing portion 43. The inclined portion of the angular elastic member 51 is fixedly connected to the inclined pushing portion 43, and the other side of the angular elastic member 51 is clamped against the inner side wall of the anti-theft ring 2. The outer side wall of the inner retaining ring 42 is fixedly connected to the inner side wall of the vertical plate 52, stably combining and positioning the extrusion cutting module 5 in a specified area inside the active space 6, so as to effectively position the angular cutting head 53 in the spaced area between the bottle cap body 1 and the anti-theft ring 2. The two positioned angular cutting heads 53 are in a position behind the corresponding connecting bridge 31, so that the tip portion of the angular cutting head 53 can align with the inner edge portion of the connecting bridge 31, effectively performing the alignment operation of the angular cutting head 53 behind the corresponding connecting bridge 31.

[0029] The supplementary inner shell 41 is spliced with the anti-theft ring 2 from the inner side area of the anti-theft ring 2, so that the supplementary inner shell 41 shields and protects the anti-theft ring 2 from the inside, enabling the supplementary inner shell 41 to be stressed prior to the anti-theft ring 2, and preventing the entire anti-theft ring 2 from being squeezed and pried by an external thin flat member. The force received by the supplementary inner shell 41 can be transmitted to the angular elastic member 51, causing the inclined portion of the angular elastic member 51 to shift towards the portion in contact with the inner side wall of the anti-theft ring 2, so that the vertical plate 52 changes its position in the active space 6 following the inclined portion of the angular elastic member 51. The vertical plate 52 drives the two angular cutting heads 53 to squeeze and cut the edge portion connecting the bottle cap body 1 and the anti-theft ring 2 of the connecting bridge 31 from behind the aligned connecting bridge 31, causing the corresponding connecting bridge 31 to break away from between the bottle cap body 1 and the anti-theft ring 2, damaging the connecting bridge 31 in the stressed area, and causing the overall anti-theft connection module 3 to be missing, effectively destroying the integrity of the anti-theft connection module 3. A groove 44 is formed in the outer side wall of the supplementary inner shell 41, and the groove 44 is located below the inclined pushing portion 43, ensuring that the supplementary inner shell 41 effectively deforms the angular elastic member 51 by pushing.

[0030] The inner splicing force-receiving module 4 is positioned and spliced inside the anti-theft ring 2. A number of extrusion positioning and cutting modules 5 are squeezed and positioned in the movable space 6. The anti-theft connection module 3 stably connects the bottle cap body 1 and the anti-theft ring 2 from the middle area. The positioning angular cutting heads 53 are between the bottle cap body 1 and the anti-theft ring 2, so that the tip parts of a number of angular cutting heads 53 are respectively from the rear of the corresponding connecting bridges 31, aligning the connecting bridges 31 to splice the inner edge parts of the bottle cap body 1 and the anti-theft ring 2. A number of compensation sealing plates 33 surround the connecting ring 32 and contact the corresponding connecting bridges 31 at both ends at the same time to effectively fill the gap space between the bottle cap body 1, the anti-theft ring 2 and the connecting bridges 31. The compensation sealing plates 33 can also block a number of extrusion positioning and cutting modules 5, so that the bottle cap body 1, the anti-theft ring 2, the anti-theft connection module 3, the inner splicing force-receiving module 4 and the extrusion positioning and cutting modules 5 are kept in an integral state and fastened to the bottle mouth part of the bottle body, and at the same time, a number of angular cutting heads 53 can be prevented from being exposed. The supplementary inner shell 41 receives force inside the anti-theft ring 2 instead of the anti-theft ring 2. The force received by the supplementary inner shell 41 is transmitted to the angular elastic member 51, causing the inclined part of the angular elastic member 51 to deflect outwards. The vertical plate 52 drives two angular cutting heads 53 from the rear of the aligned connecting bridges 31 to squeeze and cut the edge parts of the connecting bridges 31 connecting the bottle cap body 1 and the anti-theft ring 2, so that the connecting bridges 31 irreversibly break and come out between the bottle cap body 1 and the anti-theft ring 2, effectively destroying the integrity of the bottle cap. When the anti-theft ring 2 is squeezed and expanded, the integrity of the connection between the bottle cap body 1 and the anti-theft ring 2 can be regionally damaged from the squeezed area, improving the anti-counterfeiting and anti-theft effect of the bottle cap.

[0031] The working principle of the present invention is: The bottle cap body 1 is tightened on the bottle mouth part of the bottle body. The supplementary inner shell 41 is spliced with the anti-theft ring 2 from the inner area of the anti-theft ring 2. The supplementary inner shell 41 and the anti-theft ring 2 are together positioned on the circular support that expands outwards at the bottle mouth part. When the anti-theft ring 2 is pried, the supplementary inner shell 41 receives force prior to the anti-theft ring 2. The force received by the supplementary inner shell 41 is transmitted to the angular elastic member 51, causing the inclined part of the angular elastic member 51 to deflect towards the part contacting the inner side wall of the anti-theft ring 2. The vertical plate 52 changes its position in the movable space 6 following the inclined part of the angular elastic member 51, driving two angular cutting heads 53 from the rear of the aligned connecting bridges 31 to squeeze and cut the edge parts of the connecting bridges 31 connecting the bottle cap body 1 and the anti-theft ring 2, causing the corresponding connecting bridges 31 to break and come out between the bottle cap body 1 and the anti-theft ring 2, damaging the connecting bridges 31 in the force-receiving area, causing the whole of the anti-theft connection module 3 to be missing, destroying the integrity of the bottle cap, and achieving the anti-counterfeiting and anti-theft effect of the bottle cap.

[0032] The above has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
