[0036] The anti-pulling combination bottle cap provided by the present embodiment will be described in detail below in combination with the drawings. Please refer to Figures 1-4As shown, the bottle mouth sleeve 10 is provided with a plurality of through holes 11 on the lower hole wall in the circumferential direction, and a plurality of plastic clamping claws 12 are arranged in the through holes 11 in an inwardly inclined manner; the metal pipe piece 20 is provided in a tubular shape, and a plurality of metal clamping claws 21 are arranged on the metal pipe piece 20 in the circumferential direction in an inwardly inclined manner; the metal pipe piece 20 is embedded in the lower part of the bottle mouth sleeve 10, and the plurality of metal clamping claws 21 are respectively arranged in the plurality of plastic clamping claws 12 to form an integrated structure; wherein the metal pipe piece 20 and the metal clamping claws 21 are placed in the injection mold together to be injection molded as a whole when the bottle mouth sleeve 10 is injection molded.
[0037] In the embodiments of the present application, the metal pipe piece 20 and the metal clamping claws 21 are placed in the injection mold together to be injection molded as a whole when the bottle mouth sleeve 10 is injection molded, that is, the metal pipe piece 20 is embedded in the bottle mouth sleeve 10, the metal clamping claws 21 are arranged in the corresponding through holes 11 on the lower hole wall of the bottle mouth sleeve 10, and the metal clamping claws 21 have the same inclination angle as the plastic clamping claws 12 and are a component, that is, the metal clamping claws 21 are completely wrapped by the plastic clamping claws 12 after injection molding, and the metal clamping claws 21 and the plastic clamping claws 12 together abut against the bottle lip 91 at the top of the bottle mouth 90, so that the bottle mouth sleeve 10 cannot be pulled out by force without damaging the bottle mouth sleeve 10, thereby significantly improving the anti-pulling function and the anti-fake function of the bottle mouth sleeve 10 and the entire combined bottle cap.
[0038] In some embodiments, the metal pipe piece 20 and the metal clamping claws 21 are integrally formed, and such arrangement can reduce the cost.
[0039] Please refer to Figures 1-11 As shown, in some embodiments, the anti-pulling combined bottle cap further comprises an outer cap 30, an inner cap 40, an inner plug 50, an outer sleeve 60, an anti-pulling ring 70, and an anti-fake ring 80; the inner cap 40 is arranged in the outer cap 30, the anti-pulling ring 70 is arranged between the inner cap 40 and the outer cap 30, the anti-pulling ring 70 is inlaid in the groove on the outer circumferential side of the inner cap 40, and the outer circumferential side of the anti-pulling ring 70 is provided with an outer hanging table 71 (as shown in Figure 9 As shown), and the inner circumferential wall of the outer cap 30 is provided with an inner hanging table 32 (as shown in Figure 5As shown, the outer mounting platform 71 and the inner mounting platform 32 are interference-fitted to a thickness of 0.55mm or more, thereby fixing the inner cover 40 inside the outer cover 30. The outer cover 30 is made of ABS (Acrylonitrile Butadiene Styrene), and the inner cover 40 is made of PP (Polypropylene). By adding an anti-pull ring 70, the tightness between the outer cover 30 and the inner cover 40 can be increased, ensuring that the inner cover 40 cannot move. In addition, due to the characteristics of ABS material, it can withstand high temperatures of over 120°C and can withstand tensile forces of over 150 kg. If the outer cover 30 is forcibly pulled out by external force, there will be two results: first, the bottle mouth assembly 10 will be physically damaged and cannot be restored; second, the bottle mouth (usually the glass lip) will be broken and cannot be restored. Preferably, the anti-pull ring 70 is made of ABS resin.
[0040] In some embodiments, the upper part of the bottle neck assembly 10 is detachably connected to the inner cover 40, such as when the inner peripheral wall of the inner cover 40 is provided with an internal thread 41 (e.g. Figure 6 As shown), the upper outer peripheral wall of the bottle neck assembly 10 is provided with an external thread 13 that is adapted to the internal thread 41 (as shown). Figure 2 As shown, the upper part of the bottle neck assembly 10 is threaded into the inner cap 40, thereby achieving a detachable connection.
[0041] In some embodiments, the inner plug 50 is placed inside the bottle neck assembly 10, with the lower outer wall of the inner plug 50 sealing against the inner wall of the top of the bottle neck 90, and the upper outer wall of the inner plug 50 sealing against the inner wall of the bottle neck assembly 10; the outer sleeve 60 is placed outside the bottle neck assembly 10, and the upper end of the outer sleeve 60 is provided with anti-counterfeiting teeth 61 (e.g., Figure 8 As shown), the lower part of the outer cover 30 has a notch area 31 (as shown). Figure 5 As shown, the anti-counterfeiting tooth 61 is placed in the notch area 31. Rotating the outer cover 30 will definitely destroy the anti-counterfeiting tooth 61 and it cannot be restored, thereby achieving the purpose of anti-counterfeiting.
[0042] In some embodiments, the lower part of the anti-counterfeiting ring 80 is tightly disposed inside the upper end of the outer sleeve 60, and the upper part of the anti-counterfeiting ring 80 is disposed between the bottoms of the outer cover 30 and the inner cover 40, and the upper inner peripheral wall of the anti-counterfeiting ring 80 protrudes inward to form a guide platform 81 (e.g. Figure 1 As shown), the bottom outer periphery of the inner cover 40 is provided with a skirt 42 protruding outward (as shown). Figure 6As shown), in the normal sealed state, the skirt 42 of the inner cover 40 is located inside the anti-counterfeiting ring 80, and the outer cover 30 covers the anti-counterfeiting ring 80. When the outer cover 30 is rotated clockwise to open, the outer cover 30 and the inner cover 40 can be rotated out to form a 2mm annular gap between the outer cover 30 and the outer sleeve 60, exposing the anti-counterfeiting ring 80. At the same time, the skirt 42 of the inner cover 40 will rotate out of the anti-counterfeiting ring 80 and abut against the top of the anti-counterfeiting ring 80, i.e., the guide platform 81, so that the outer cover 30 cannot return to its original position and can no longer cover the anti-counterfeiting ring 80, so that the anti-counterfeiting ring 80 is always exposed. The outer surface of the anti-counterfeiting ring 80 is provided with anti-counterfeiting markings, providing a good anti-counterfeiting effect, such as the word "opened" set here (e.g. Figure 10 (As shown). Preferably, the skirt 42 of the inner cover 40 has a chamfer, and the upper guide 81 of the anti-counterfeiting ring 80 also has a chamfer, so that the skirt 42 of the inner cover 40 can be unscrewed from the anti-counterfeiting ring 80. More preferably, the anti-counterfeiting ring 80 is made of ABS resin.
[0043] In some embodiments, the anti-pull-out combination cap also includes a QR code label 43, which is placed on top of the inner cap 40. A transparent area is provided on the top of the outer cap 30 to facilitate scanning the QR code label 43 on the top of the inner cap 40. Specifically, laser engraving technology can be used to peel off the paint in the middle of the top of the outer cap 30, thereby revealing a transparent area of φ17.5.
[0044] The implementation principle of this embodiment is as follows: The metal tube 20 and metal claw 21 are injection molded together as a single unit during the injection molding of the bottle neck assembly 10. After injection molding, the metal claw 21 is completely enclosed by the plastic claw 12. The metal claw 21 and the plastic claw 12 have the same inclination angle and are a single component. During assembly, the inner plug 50 is first placed inside the bottle neck assembly 10. Then, the upper part of the bottle neck assembly 10 is connected to the inner cap 40 via threads. Next, the anti-counterfeiting ring 80 is installed from top to bottom onto the outer side of the inner cap 40 on the upper part of the bottle neck assembly 10. Then, the anti-pull ring 70 is embedded in the groove on the outer side of the inner cap 40. The assembled semi-finished product is then... The entire assembly is pressed into the outer sleeve 60, ensuring the lower part of the anti-counterfeiting ring 80 fits tightly against the upper end of the outer sleeve 60. Then, the notch 31 on the outer cap 30 is aligned with the anti-counterfeiting teeth 61 on the outer sleeve 60. After the outer cap 30 is pressed in, the inner mounting platform 32 on the inner side of the outer cap 30 is engaged with the outer mounting platform 71 on the outer side of the anti-pull-out ring 70, thus assembling a complete anti-pull-out bottle cap assembly. Finally, the entire anti-pull-out bottle cap assembly is pressed from top to bottom onto the bottle neck 90. The protruding lip 91 at the top of the bottle neck 90 passes through the metal claw 21 and the plastic claw 12 and is held in place by them, preventing the bottle neck assembly 10 from being pulled out of the bottle neck 90. If the bottle neck assembly 10 is forcibly pulled out, either the bottle neck 90 or the bottle neck assembly 10 will break, both resulting in irreparable damage, thus achieving the purpose of preventing pull-out and anti-counterfeiting.
[0045] Clockwise screwing off the outer cover 30, when the outer cover 30 normal opening, at this time the outer cover 30 and outer sleeve 60 between the 2mm annular gap, while you can see the anti-counterfeiting ring 80 and prompt “has been opened”.
[0046] The above only for the preferred embodiments of the present application, and is not intended to limit the present application, for those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the scope of protection of the present application.
