Referring to fig. 1, fig. 1 is a schematic diagram illustrating an assembled structure of a bottle cap 10 according to an embodiment of the present application. Referring to fig. 2 and 3, the bottle cap 10 provided in an embodiment of the present application includes: outer cap 100, sealing cap 200, inner plug 300, outer jacket 400, and inner jacket 500; the outer cover 100 is covered on the upper end of the outer cover 400, a press-fit cavity is formed between the outer cover 100 and the outer cover 400 in a matched mode, the inner plug 300 is arranged in the press-fit cavity, the upper end of the sealing cover 200 is abutted with the outer cover 100, the lower end of the sealing cover 200 is abutted with the inner plug 300, the inner sleeve 500 is arranged in the outer cover 400, and the upper end of the inner sleeve 500 is provided with a bottleneck claw 510 capable of elastically deforming.

The bottle cap 10 can be applied to container bottles such as wine bottles, cosmetic bottles and the like, particularly small-capacity container bottles, such as 50ml or 100ml wine bottles.

The exterior cover 100 and the exterior cover 400 may be made of plastic material such as ABS (Acrylonitrile Butadiene Styrene plastic, acrylonitrile butadiene styrene copolymer). The material has certain hardness, and can be used for surface decoration, for example, marks such as product trademarks can be printed on the outer surface of the outer sleeve 400, and marks such as winning two-dimensional codes and anti-counterfeiting two-dimensional codes can be printed on the inner surface and the outer surface of the outer cover 100 respectively.

The sealing cover 200 may be made of a transparent material, such as PP (Polypropylene). Transparent material, the user can easily see the mark in the exterior cover 100, such as a winning two-dimensional code.

The inner plug 300 may be made of PE (polypropylene, polyethylene tube) and the like, which has a certain elasticity and can better seal the mouth of the container bottle.

The inner sleeve 500 may be made of a material capable of being elastically deformed, such as PET (polyethylene terephthalate, polyethylene glycol terephthalate) and PC (Polycarbonate), and is capable of being deformed by an external force and being restored to an original shape after the external force is removed. PET materials may be preferred in view of the safety performance of food. The material of the bottleneck claw 510 may be the same as that of the inner sleeve 500, and the bottleneck claw and the inner sleeve may be integrally formed by injection molding.

The press-fitting process of the above bottle cap 10 is described as follows:

before press fitting, the outer cap 100 is first covered and fitted on the upper port of the outer cap 400, the inner sleeve 500 is set inside the outer cap 400, and the sealing cap 200 and the inner plug 300 are sequentially fitted into the press-fitting cavity formed by the cooperation between the outer cap 100 and the outer cap 400. The inner plug 300 is aligned to the bottle mouth, and then the bottle mouth is sleeved outside the inner plug 300 or inserted into the inner plug 300 until the inner plug 300 is tightly propped up, so that the inner plug 300 is in sealing fit with the bottle mouth of the container bottle and the sealing cover 200, at the moment, the bottle mouth claw 510 of the inner sleeve 500 is extruded into the bottle lip 20a of the bottle mouth and bounces back to the original state after entering the bottle lip 20a, so that the bottle cap 10 can be effectively matched with the bottle lip 20a, and the press-fitting of the bottle cap 10 is completed.

As the bottle cap 10 is added, the bottle mouth claw 510 on the inner sleeve 500 can quickly rebound to the original shape after being extruded and deformed by the bottle lip 20a due to elastic deformation in the process of pressing and clamping the bottle, and can be effectively matched with the bottle lip 20a, so that the problem that the bottle mouth claw on the outer cap 100 cannot rebound to the original shape after being extruded and deformed by the bottle lip 20a due to too poor toughness of the outer cap 100 of the existing bottle cap 10 can be avoided, the bottle cap 10 can be prevented from being pulled up in the process of pressing and clamping the bottle cap 10 can be avoided, and the pressing and clamping efficiency of the bottle cap 10 can be improved; in addition, the bottle cap 10 seals the container bottle by the way that the sealing cap 200 is matched with the inner plug 300, and the inner sleeve 500 can not be directly contacted with the solution (such as wine) in the container bottle, so that the risks of food safety and sanitation and the phenomenon of liquid leakage are effectively reduced. In summary, the bottle cap 10 of the present application can be applied to the bottle cap 10 of a small-capacity container bottle, such as a 50ml or 100ml wine bottle, and can effectively solve the problems of the bottle cap 10 such as pulling up, sanitation, leakage and complex assembly.

In some embodiments of this application, the outer cap 100 may be threadably mounted on the upper end of the outer jacket 400. In this way, the user can conveniently open the bottle cap 10. For example, referring to fig. 2 and 3, the inner wall of the outer cap 100 is provided with threads, and the outer wall of the outer cap 400 is provided with threads that are adapted to the threads on the inner wall of the outer cap 100.

Alternatively, as shown in fig. 2, a screw portion 120 is provided on the outer wall of the outer cap 100. The screwing part 120 facilitates the user to screw the outer cap 100. Alternatively, the screwing part 120 may be an annular rack formed on the exterior cover 100.

Alternatively, as shown in FIG. 2, the outer sleeve 400 may include a small diameter section 410 and a large diameter section 420 connected, with the large diameter section 420 having an outer diameter greater than the outer diameter of the small diameter section 410. The junction between the large diameter section 420 and the small diameter section 410 of the outer case 400 may form a third step surface in a ring shape, and when the outer cap 100 is screwed onto the outer case 400, once the outer cap 100 abuts against the third step surface, it is determined that the outer cap 100 is mounted in place, and at this time, it is not necessary to continue screwing the outer cap 100. As an example, the outer wall of the small diameter section 410 of the outer jacket 400 is provided with threads that mate with threads on the inner wall of the outer cap 100.

In some embodiments of this application, referring to fig. 1 and 2, a stopper 110 is provided on the exterior cover 100, and a tamper-proof portion 430 protruding toward the exterior cover 100 is formed on the exterior cover 400, and the tamper-proof portion 430 is used to prevent the stopper 110 from rotating until the tamper-proof portion 430 breaks. In the process of opening the bottle cap 10, the outer cap 100 rotates relative to the outer cap 400, when the anti-counterfeiting part 430 on the outer cap 400 touches the stop part 110 of the outer cap 100, the stop part 110 is prevented from continuing to rotate, and if the bottle cap 10 is continuously opened, the anti-counterfeiting part 430 on the outer cap 400 is deformed or even broken, and under the condition, the bottle cap 10 can be clearly judged to be opened, so that an effective anti-counterfeiting effect is achieved. As an example, the tamper evident portion 430 is disposed on the minor diameter section 410 of the outer sleeve 400.

Alternatively, as shown in fig. 1 and 2, the stopper 110 has a groove structure formed on the outer cover 100, a groove wall of the stopper 110 penetrates through the outer cover 100 to a side wall close to the outer sleeve 400, and an opening of the stopper 110 is opposite to the inner plug; before the bottle cap 10 is opened, the tamper proof part 430 is received in the stopper 110 (see fig. 1). Before the bottle cap 10 is opened, the anti-counterfeiting part 430 is accommodated in the stopper 110; when the outer cap 100 is screwed for a predetermined angle, one side wall of the anti-counterfeiting part 430 abuts against the anti-counterfeiting part 110, the anti-counterfeiting part 430 prevents the anti-counterfeiting part 110 from continuing to rotate along with the outer cap 100, and the anti-counterfeiting part 430 has transverse shearing relative to the anti-counterfeiting part 110, so that the anti-counterfeiting part 430 deforms and even breaks in the rotating process of the outer cap 100.

Alternatively, the tamper-proof part 430 may include a plurality of tamper-proof teeth spaced apart along the circumference of the outer jacket 400; as shown in fig. 2, the device may further include a main body 431 and a support 432 connected to each other; the main body 431 may be provided with a marking area for indicating the opening direction of the bottle cap 10; the support 432 may include a plurality of support bars spaced apart along the circumference of the jacket 400. Wherein, the sign of opening, can be sprayed, printed or carved on the mark area to remind the user of the opening direction of the bottle cap 10.

In some embodiments of this application, referring to fig. 2, the flap 200 may include a cap portion 210 and a first sealing portion 220 connected, the cap portion 210 having an outer diameter greater than the outer diameter of the first sealing portion 220, the cap portion 210 being configured to abut the outer cap 100, the first sealing portion 220 being sleeved on the exterior of the inner plug 300. As one example, the outer diameter of the cover dome section 210 may be greater than the outer diameter of the small diameter section 410 of the outer sleeve 400. In the press-fitting process of the bottle cap 10, the closure cap 200 cannot fall out of the press-fitting cavity formed by the cooperation between the outer cap 100 and the outer cap 400 due to the blocking of the small diameter section 410 of the outer cap 400, so that the normal press-fitting process of the bottle cap 10 can be ensured. It should be noted that, before the bottle cap 10 is press-fitted, the cap 200 may be first placed in the outer cap 100, and then the outer cap 100 is assembled to the outer jacket 400,

in some embodiments of this application, closure 10 further includes a second retaining assembly for circumferentially retaining closure cap 200 on outer cap 100. The second limiting component can prevent the sealing cover 200 from driving the inner plug 300 to rotate, so that the tightness of the bottle cap 10 can be ensured.

Optionally, as shown in fig. 2, the second limiting assembly may include a plurality of fourth limiting protrusions 620 and a plurality of fifth limiting protrusions (not shown in the drawings) all distributed at intervals along the circumferential direction of the sealing cap 200, wherein the fourth limiting protrusions 620 are disposed on the top surface of the sealing cap 200, the fifth limiting protrusions are disposed on the inner surface of the outer cap 100, and the fifth limiting protrusions are interposed between two corresponding adjacent fourth limiting protrusions 620. By the cooperation of the fourth limiting protrusion 620 and the fifth limiting protrusion, the rotation of the sealing cover 200 can be stopped. As an example, a fourth limit protrusion 620 is provided on the top cover portion 210 of the flap 200.

The fourth limiting protrusion 620 may be disposed on the sealing cover 200 in an injection molding manner, and the fifth limiting protrusion may also be disposed on the outer cover 100 in an injection molding manner. Regarding the number of the fourth limiting protrusions 620 and the fifth limiting protrusions, the present application is not particularly limited, as long as the sealing cover 200 can be effectively circumferentially limited, and for example, 30 fourth limiting protrusions 620 are uniformly disposed on the sealing cover 200 along the circumferential direction, and correspondingly, 30 fifth limiting protrusions are uniformly disposed on the outer cover 100 along the circumferential direction.

In some embodiments of the present application, as shown in fig. 2 and 5, the inner plug 300 may include a second sealing portion 310, a transition portion 320 and a third sealing portion 330 sequentially connected, the outer diameters of the transition portion 320, the second sealing portion 310 and the third sealing portion 330 sequentially decrease, the second sealing portion 310 is sealingly disposed in the closure cap 200, the third sealing portion 330 is sealingly disposed in the bottle mouth, and the transition portion 320 abuts between the closure cap 200 and the bottle mouth. The inner plug 300 with the structure not only can ensure the sealing of the container bottle, but also is convenient for the assembly between the inner plug 300 and the sealing cover 200 as well as between the inner plug and the bottle mouth.

In some embodiments of the present application, as shown in fig. 5, an annular second step surface 300a is provided on an outer surface of the inner plug 300, the second step surface 300a is used for abutting against a bottle mouth, and a plurality of second rotation stopping protrusions 720 are provided on the second step surface 300a at intervals along a circumferential direction of the inner plug 300. The second step surface 300a is an end surface of the transition portion 320 away from the sealing cover 200. The second rotation stopping protrusion 720 can prevent the inner plug 300 from rotating relative to the bottle mouth, and can stop rotation of the inner plug 300. As an example, the end surface of the finish may be provided with a plurality of rotation stopping protrusions in the circumferential direction that cooperate with the second rotation stopping protrusions 720 on the inside plug 300. The second rotation stopping protrusions 720 may be uniformly provided on the second stepped surface 300a, so that more effective circumferential limitation of the inner plug 300 may be performed. Regarding the number of the second rotation stopping protrusions 720 provided on the second step surface 300a, the embodiment of the present application is not particularly limited as long as the inner plug 300 can be circumferentially limited.

In some embodiments of the present application, the closure 10 further includes a first stop assembly for circumferentially stopping the inner sleeve 500 on the outer sleeve 400. The inner case 500 is disposed on the outer case 400 by the first limiting assembly, thereby facilitating assembly of the bottle cap 10.

Further, in some embodiments of the present application, as shown in fig. 2 and 4, the first limiting component includes a plurality of first limiting protrusions 610 and a plurality of second limiting protrusions (not shown in the drawings) that are all distributed at intervals along the circumferential direction of the inner sleeve 500, the first limiting protrusions 610 are disposed on the outer surface of the inner sleeve 500, the second limiting protrusions are disposed on the inner surface of the outer sleeve 400, and the second limiting protrusions are interposed between two corresponding adjacent first limiting protrusions 610. The inner sleeve 500 is assembled on the outer sleeve 400 by the cooperation of the first and second limit protrusions 610.

Specifically, referring to fig. 3, an annular first step surface 400a may be provided on the inner surface of the outer sleeve 400, second limit protrusions are provided on the first step surface 400a and the side surfaces of the outer sleeve 400, and first limit protrusions 610 are provided on the top surface and the side surfaces of the inner sleeve 500. The first and second limiting protrusions 610 and 610 are distributed in this way, so that the inner sleeve 500 can be more effectively stopped from rotating.

The first limiting protrusion 610 may be disposed on the inner sleeve 500 in an integrally molded manner such as injection molding, and the second limiting protrusion may be disposed in the first step surface 400a of the outer sleeve 400 and the large diameter section 420 of the outer sleeve 400 in an integrally molded manner such as injection molding. Regarding the number of the first limiting protrusions 610 and the second limiting protrusions, the number of the first limiting protrusions 610 and the second limiting protrusions is not particularly limited, and as long as the inner sleeve 500 can be effectively limited circumferentially, for example, 3 first limiting protrusions 610 are uniformly arranged on the top surface of the inner sleeve 500 in the circumferential direction and 8 first limiting protrusions 610 are uniformly arranged on the side surface of the inner sleeve 500 in the circumferential direction, correspondingly, 3 second limiting protrusions are uniformly arranged on the first step surface 400a of the outer sleeve 400 in the circumferential direction and 8 first limiting protrusions 610 are uniformly arranged on the side surface of the large-diameter section 420 of the outer sleeve 400 in the circumferential direction.

In some embodiments of the present application, as shown in fig. 4, a plurality of first rotation stopping protrusions 710 may also be provided on the inner wall of the inner sleeve 500, which are spaced apart along the circumferential direction of the inner sleeve 500. The first rotation stopping protrusion 710 can prevent the inner sleeve 500 from rotating relative to the bottle mouth, and can stop rotation of the inner sleeve 500. As an example, a plurality of rotation stopping protrusions may be circumferentially provided on the outer wall of the bottle mouth to cooperate with the first rotation stopping protrusions 710 on the inner sleeve 500. Regarding the number of the first rotation stopping protrusions 710 provided on the inner sleeve 500, the embodiment of the present application is not particularly limited as long as the inner sleeve 500 can be circumferentially limited.

In some embodiments of the present application, referring to fig. 4, the distance between the finish jaws 510 and the axis of the closure 10 increases gradually in the top-to-bottom direction. The shaped finish jaws 510 further facilitate the entrance of the finish jaws 510 into the lips 20a of the finish in the event of compression deformation.

In some embodiments of the present application, referring to fig. 4, the number of the bottle jack catches 510 is plural, and the plural bottle jack catches 510 are uniformly distributed along the circumferential direction of the inner sleeve 500.

Still further embodiments of the present application provide a container bottle, which includes a bottle body 20 and a bottle cap 10 as described in any one of the above, wherein a bottle mouth of the bottle body 20 is sealed and sleeved outside an inner plug 300 of the bottle cap 10 or is sealed and inserted into the inner plug 300, and a bottle mouth claw 510 of an inner sleeve 500 of the bottle cap 10 is clamped in a bottle lip 20a of the bottle body 20.

As an example, the mouth of the bottle 20 may be sealingly sleeved on the outside of the inner plug 300.

According to the container bottle, the inner sleeve 500 is added on the bottle cap 10, and in the process of pressing and clamping the bottle, the bottle mouth claw 510 on the inner sleeve 500 can quickly rebound to the original shape after being pressed and deformed by the bottle lip 20a due to elastic deformation and can be effectively matched with the bottle lip 20a, so that the problem that the bottle mouth claw 510 cannot rebound to the original shape after being pressed and deformed by the bottle lip 20a due to too poor toughness of the outer cap 100 of the existing bottle cap 10 can be avoided, the bottle cap 10 can be prevented from being pulled up in the process of pressing and clamping the bottle cap 10 can be improved; in addition, the bottle cap 10 seals the container bottle in a way that the sealing cap 200 is matched with the inner plug, and the inner sleeve 500 can not be directly contacted with the solution (such as wine) in the container bottle, so that the risks of food safety and sanitation and the phenomenon of liquid leakage are effectively reduced. In summary, the container bottle of the present application can be applied to the bottle cap 10 of a small-capacity container bottle, such as a 50ml or 100ml wine bottle, and can effectively solve the problems of the bottle cap 10, such as pulling up, sanitation, leakage and complex assembly.
