TECHNICAL FIELD
[0001] The present application relates to the technical field of bottle caps, in particular to a broken-petal anti-pulling bottle cap and a container bottle. BACKGROUND
[0002] In the whole chain of production, circulation and consumption of wine products, product traceability, anti-fake authenticity and quality assurance are always the core demands of the industry, and as the key link between products and consumers, the effectiveness of the anti-fake design of the wine bottle cap directly determines the safety of the product and the brand credibility.
[0003] At present, the mainstream wine bottle caps on the market generally integrate a two-dimensional code traceability function to realize product information query, marketing interaction and other value-added services, and the broken-petal (also known as anti-fake tooth or anti-fake petal) structure is set to strengthen the opening identification. When the consumer opens the bottle cap in the normal way, the broken-petal will be irreversibly broken due to rotation of the bottle cap, and the product has been opened can be directly prompted by the appearance of the broken-petal.
[0004] However, when the non-standard opening method such as strong pulling and prying is used by the lawbreaker, the broken-petal remains intact because it is not subjected to torsional force under the action of “twisting”. In this case, the lawbreaker can illegally open the bottle cap without damaging the appearance of the broken-petal, and then implement illegal behaviors such as scanning the two-dimensional code and replacing the wine in the bottle.

DETAILED DESCRIPTION
[0018] Example 1 Referring to Figures 1-6 A broken petal pull-preventing bottle cap includes an inner sleeve, an inner cover 1, a lower outer cover 2, and an upper outer cover. The inner cover 1 is threadedly connected to the upper end of the inner sleeve, i.e., the upper end of the inner sleeve is provided with external threads, and the inner cover 1 is provided with internal threads connected with the external threads. The lower outer cover 2 is fixedly sleeved on the lower end of the inner sleeve, i.e., the lower outer cover 2 forms an integral whole with the inner sleeve; the upper outer cover is composed of a cover body 5 and a cylinder body 6, the cover body 5 is fixedly sleeved on the outside of the inner cover 1, and the cylinder body 6 is fixedly sleeved on the outside of the cover body 5, and after assembly, the cover body 5, the cylinder body 6, and the inner cover 1 form an integral whole.
[0019] Referring to Figure 1 The top of one side of the lower outer cover 2 is connected with a broken petal 201 through several breakable ribs, the barrel 6 is provided with a notch 601 for accommodating the broken petal 201, the breakable ribs are thin and easy to break, when the upper outer cover is rotated to open the bottle cap, the barrel 6 is rotated to exert a torsion on the broken petal 201, so that the broken petal 201 is damaged. The two ends of the broken petal 201 are provided with extension portions 2011, the inner wall of the barrel 6 is provided with anti-pulling grooves 602 on the two sides of the notch 601 for cooperating with the extension portions 2011, when a criminal tries to forcibly pull the upper outer cover, the anti-pulling grooves 602 exert a pulling force on the extension portions 2011, so that the broken petal 201 is also damaged, and the anti-fake effect of the broken petal 201 is improved. In addition, a plurality of vertical grooves can be arranged at intervals on the inner side of the broken petal 201, so as to weaken the strength of the broken petal 201, and the broken petal 201 itself is also easy to be damaged.
[0020] As an option, the fixing mode of the two components (i.e. the cover body 5 and the barrel 6) of the upper outer cover in the embodiment is as follows: the cover body 5 and the barrel 6 are in interference fit, so that the barrel 6 and the cover body 5 are fastened; in addition, the inner wall of the barrel 6 is provided with first anti-rotation teeth 603, and the outer wall of the cover body 5 is provided with second anti-rotation teeth 501, the first anti-rotation teeth 603 cooperate with the second anti-rotation teeth 501 to further limit the relative rotation of the cover body 5 and the barrel 6, so as to ensure that the barrel 6 can rotate with the cover body 5 when the cover body 5 is rotated to open the bottle cap. In other embodiments, the cover body 5 and the barrel 6 can of course also adopt other fixing modes, for example, the rotation is limited by anti-rotation, and the relative axial displacement is limited by axial limiting structure.
[0021] Further, the top of each of the extension portions 2011 at the two ends of the broken petal 201 in the embodiment is provided with a protruding portion 2012, and it should be understood that, on this basis, the anti-pulling groove 602 should be matched with the shape formed by the extension portion 2011 and the protruding portion 2012. It is worth mentioning that, when the upper outer cover is rotated to open the bottle cap, the protruding portion 2012 increases the force receiving area of the broken petal 201, so that the broken petal 201 is more easily damaged and the damage effect is better, and it is not easy to restore.
[0022] It should be understood that, when the bottle cap is assembled, the inner sleeve and the lower outer cover 2 are assembled first, the inner cap 1 is screwed, the barrel 6 is placed in an eccentric state with the lower outer cover 2, the barrel 6 is moved radially to make it concentric with the lower outer cover 2 (at this time, the broken petal 201 is in the anti-pulling groove 602), and finally the cover body 5 is pressed in.
[0023] The top surface of the lower outer cover 2 is provided with a positioning boss 202. In this embodiment, the positioning boss 202 is annular in structure (in other embodiments, the positioning boss 202 can also be arc-shaped, which can be one or more arc-shaped segments). The outer diameter of the positioning boss 202 matches the inner diameter of the barrel 6. It is worth noting that, due to the eccentric lowering of the barrel 6 during installation, the barrel 6 needs to be made concentric with the lower outer cover 2 after avoiding the broken petals 201. The outer diameter of the positioning boss 202 matches the inner diameter of the barrel 6, forming a positioning structure, which can well ensure that the barrel 6 is concentric with the lower outer cover 2. In addition, it is easy to understand that, since the barrel 6 needs to be lowered eccentrically, an avoidance groove 604 needs to be provided on the inner wall of the bottom of the barrel 6 on the side opposite to the anti-pulling groove 602 in actual application. It is easy to understand that the axial dimension of the avoidance groove 604 should be greater than the height dimension of the positioning boss 202, and the radial dimension of the avoidance groove 604 should be ensured to be able to completely avoid the broken petals 201 when the barrel 6 is lowered eccentrically, so as to ensure that the barrel 6 does not interfere during installation.
[0024] In this embodiment, the upper end of the cover body 5 is provided with a positioning step 502, the upper end of the barrel 6 abuts against the positioning step 502, and the lower end abuts against the top surface of the lower outer cover 2. In other embodiments, the upper end of the barrel 6 can of course not be limited.
[0025] Referring to Figure 6 , Figure 7 and Figures 1-3 , as an option, the fixing mode of the cover body 5 and the inner cover 1 in this embodiment is as follows. The bottom of the inner cover 1 is provided with a first limiting step 101, and the inner wall of the cover body 5 is provided with a plurality of first limiting hanging steps 503 in the circumferential direction. After the cover body 5 is pressed in during assembly, the first limiting step 101 abuts against the top surface of the first limiting hanging step 503, limiting the relative axial displacement of the cover body 5 and the inner cover 1, and increasing the difficulty of forcibly pulling by illegal persons. The inner wall of the cover body 5 is provided with third anti-rotation teeth 504, and the outer wall of the inner cover 1 is provided with fourth anti-rotation teeth 102. The third anti-rotation teeth 504 and the fourth anti-rotation teeth 102 cooperate to limit the relative rotation of the cover body 5 and the inner cover 1, and ensure that rotating the outer cover can drive the inner cover 1 to rotate, thereby achieving the opening of the bottle cap.
[0026] Referring to Figures 8-10 and Figure 11As an alternative, the fixing mode of the lower outer cover 2 and the inner sleeve in the embodiment is as follows: the top of the lower outer cover 2 is internally provided with a first limiting ring 203, the outer wall of the inner sleeve is provided with a second limiting step 401, and the bottom surface of the first limiting ring 203 is abutted against the second limiting step 401 after the lower outer cover 2 is assembled; the inner wall of the lower outer cover 2 is circumferentially provided with a plurality of second limiting hanging steps 204 capable of abutting against the bottom surface of the inner sleeve, so that the relative axial displacement of the lower outer cover 2 and the inner sleeve is limited. The inner wall of the lower outer cover 2 is provided with a fifth anti-rotation tooth 205, the outer wall of the inner sleeve is provided with a sixth anti-rotation tooth 402, the fifth anti-rotation tooth 205 cooperates with the sixth anti-rotation tooth 402 to limit the relative rotation of the lower outer cover 2 and the inner sleeve.
[0027] As an alternative, the inner sleeve includes an upper inner sleeve 3 and a lower inner sleeve 4, and the upper inner sleeve 3 and the lower inner sleeve 4 are integrally injection molded by two different materials. On this basis, the upper inner sleeve 3 is connected with the inner cover 1 through threads, and the lower inner sleeve 4 is fixed with the lower outer cover 2. In actual application, the upper inner sleeve 3 in contact with the wine body can be made of PET material meeting the food requirements, and the lower inner sleeve 4 is made of a material with higher hardness, such as metal, steel plastic or the like, to ensure that the lower inner sleeve 4 is effectively fixed at the bottle opening.
[0028] Further, the upper end of the inner wall of the lower inner sleeve 4 is provided with a second limiting ring 403, and the lower end of the outer wall of the upper inner sleeve 3 is provided with a ring groove 301 cooperating with the second limiting ring 403, so as to ensure that the lower inner sleeve 4 and the upper inner sleeve 3 form an integral body after injection molding. The inner wall of the second limiting ring 403 is provided with a seventh anti-rotation tooth 4031, and the sidewall of the ring groove 301 is provided with an eighth anti-rotation tooth 3011, the seventh anti-rotation tooth 4031 cooperates with the eighth anti-rotation tooth 3011 to limit the relative rotation of the lower inner sleeve 4 and the upper inner sleeve 3, avoiding the situation that the two are twisted off under the action of torsion.
[0029] The embodiment also provides a container bottle, which includes a bottle body (not shown in the figure) and the bottle cap described above. Taking a wine bottle as an example, it should be known by those skilled in the art that it also includes an inner plug 7. In actual application, the upper end of the inner plug 7 is in interference fit with the upper inner sleeve 3 to form a sealing pair, and the lower end of the inner plug 7 is embedded in the bottle opening to form a sealing pair. Generally, in order to avoid the whole bottle cap being pulled out and filled with fake wine, a clamping groove is arranged at the bottle opening, a clamping claw is arranged on the inner wall of the lower inner sleeve 4, and after the bottle cap is installed on the wine bottle, the clamping claw is clamped into the clamping groove to form an anti-pulling structure.
[0030] Embodiment 2 Reference Figure 12 and The difference between the embodiment and the embodiment 1 is that only the protruding part 2012 is arranged on the top of the extension part 2011 at one end of the broken petal 201; on this basis, it should be understood that the shape of the anti-pulling groove 602 on one side of the gap 601 on the cylinder body 6 is matched with the extension part 2011, and the shape of the anti-pulling groove 602 on the other side of the gap 601 is matched with the common structure of the extension part 2011 and the protrusion 2012.
[0031] The above only is the preferred embodiment of the present application, and is not used to limit the present application, for the person skilled in the art, the present application can have various changes and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the protection scope of the present application.
