DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example

[0024] like Figure 1-5 As shown, in this embodiment, a kind of anti-counterfeit bottle cap structure is mainly disclosed, and its main structure comprises a bottle mouth 1, an inner cover 2 and an outer cover 4, the inner cover 2 is threadedly connected with the bottle mouth 1, an anti-extraction ring 3 is arranged between the inner cover 2 and the outer cover 4, the outer wall of the inner cover 2 is provided with a first annular groove 21, the top of the anti-extraction ring 3 is provided with a first protrusion 31 which is gathered inwardly, the first protrusion 31 is buckled in the first annular groove 21, the outer wall of the anti-extraction ring 3 is provided with a second annular groove 32, the outer cover 4 is provided with a second protrusion 41, and the second protrusion 41 is buckled in the second annular groove 32; it should be noted that the existing conventional structure usually directly sets the outer cover 4 on the inner cover 2, due to the limitation of the mold structure, the outer cover 4 cannot be made into a full circle of buckles to buckle the inner cover 2, and usually can only be made into several sections of buckles with larger intervals on the inner circumference of the outer cover 4, and at the same time, the inner cover 2 is usually made of PP or PE material, which is soft in texture, while the outer cover is usually made of ABS material, which is hard in texture, so that The buckling strength of the outer cover 4 and the inner cover 2 is limited and is easily pulled apart; the utility model adds an anti-pulling ring 3 between the outer cover 4 and the inner cover 2, and the anti-pulling ring 3 can be made of ABS material, and the first ring groove 21 is set as a full-circle buckle position, and the first protrusion 31 can be set as a full-circle structure, or it can be set as a protrusion structure with a smaller interval. Through the buckling of the first protrusion 31 and the first ring groove 21, the anti-pulling ring 3 and the inner cover 2 are buckled in a full circle, and the anti-pulling ring 3 and the outer cover 2 are buckled in a full circle. The anti-pulling ring 3 and the outer cover 2 are made of the same material with a relatively hard texture, and even if they are buckled at intervals, the anti-pulling ring 3 and the outer cover 4 can achieve a strong buckling strength, thereby indirectly achieving a full-circle buckling between the inner cover 2 and the outer cover 4, and then the inner cover 2, the anti-pulling ring 3 and the outer cover 4 are connected as a whole. When the bottle cap is not opened, the inner cover 2 and the outer cover 4 are not easily pried apart and separated, thereby increasing the anti-pulling ability between the outer cover 4 and the inner cover 2, effectively preventing the bottle cap from being illegally disassembled, and improving the anti-counterfeiting performance and safety of the product.

[0025] Furthermore, in the specific implementation, Figure 3 , 4 As shown, the outer wall of the inner cover 2 provided in the embodiment of the utility model is provided with a first transmission tooth 22, and the anti-extraction ring 3 is provided with a second transmission tooth 33. The first transmission tooth 22 is meshed with the second transmission tooth 33 to prevent the inner cover 2 from rotating with the anti-extraction ring 3; preferably, as Figure 4 , 5As shown, the outer wall of the anti-pullout ring 3 is provided with a snap-in groove 34, and the inner wall of the outer cover 4 is provided with a snap-in block 42 which is snap-fitted with the snap-in groove 34, which plays a role in stopping the anti-pullout ring 3 and the outer cover 4 from rotating; thereby preventing the inner cover 2, the anti-pullout ring 3 and the outer cover 4 from rotating; at the same time, the rotation of the outer cover 4 can be transmitted to the inner cover 2 through the anti-pullout ring 3, thereby realizing the synchronous rotation of the outer cover 4, the anti-pullout ring 3 and the inner cover 2.

[0026] Furthermore, in the specific implementation, Figure 1 , 2 As shown, in the embodiment of the utility model, the outer sleeve 5 of the bottle mouth 1 is fixedly provided with a middle sleeve 5, and the bottom ends of the outer cover 4 and the anti-extraction ring 3 are both in contact with the top of the middle sleeve 5; specifically, a third protrusion 23 extends outward from the bottom of the inner cover 2, and a fourth protrusion 51 is provided on the inner side of the top of the middle sleeve 5, and the third protrusion 23 and the fourth protrusion 51 are interference-fitted; a groove 52 for clamping the third protrusion 23 is provided on the top of the middle sleeve 5. It should be noted that when the bottle cap is installed, the bottom ends of the outer cover 4 and the anti-extraction ring 3 are both in contact with the top of the middle sleeve 5 The outer cover 4 and the middle cover 5 are connected by the third protrusion 23, and the inner cover 2 is connected by the third protrusion 23 to the middle cover 5, thereby ensuring a firm connection with the bottle mouth 1 and increasing the fixity of the bottle cap. When the bottle cap is opened, the bottle cap rises as a whole, and the inner cover 2 is pulled outward, gradually breaking away from the limit of the fourth protrusion 51 of the middle cover 5. After opening, due to the limitation of the groove 52, the bottom of the inner cover 2 cannot be re-engaged with the middle cover 5, and there is a gap between the outer cover 4 and the middle cover 5, so they cannot be re-engaged with the middle cover 5, thereby further realizing the anti-counterfeiting function.

[0027] Furthermore, in a specific implementation, the second protrusions 41 provided in the embodiment of the utility model are evenly spaced in the outer cover 4 , and the outer cover 4 is firmly connected to the anti-pulling ring 3 by the engagement of the second protrusions 41 with the second annular groove 32 .

[0028] Furthermore, in the specific implementation, Figure 1 As shown, a limiting strip 43 abutting against the top of the inner cover 2 is provided inside the outer cover 4 provided in the embodiment of the utility model. It should be noted that the limiting strip 43 can be a plurality of limiting strips 43 evenly spaced and vertically arranged inside the outer cover 4. The limiting strip 43 and the outer cover 4 are integrally formed. After the inner cover 2 is installed in place, the bottom end of the limiting strip 43 abuts against the inner cover 2, thereby ensuring the correct alignment of the inner cover 2 and the outer cover 4 and avoiding the problem of improper assembly.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
