DETAILED DESCRIPTION

[0032] Example 1

[0033] refer to Figures 1-4 A rotating snap-fit bottle cap comprises an outer cover 1, an inner cover 2, a lining cover 3 and a top sheet 4.

[0034] refer to Figure 8 、 Figure 9 and Figure 12 , while combining Figure 3 and Figure 4, a limiting platform 101 for restricting the upward movement of the inner cover 2 is provided at the top of the outer cover 1, two symmetrically arranged latches 401 about the axis are provided at the bottom of the top piece 4, and a latch hole 1011 for installing the latch 401 and restricting its upward movement is provided on the limiting platform 101. As an option, in this embodiment, the latch 401 includes a latch body 4011 and a barb 4012 provided at the bottom of the latch body 4011, and the barb 4012 hooks the bottom surface of the latch hole 1011. Of course, in other embodiments, the latch 401 can also be designed into other structures. For example, the latch 401 is a tooth extending towards the center of the top piece 4, and a tooth hole capable of cooperating with the tooth is provided on the side wall of the latch hole 1011. In addition, it should be understood that to enable the latch 401 to be inserted into the latch hole 1011, the latch 401 should have a certain elasticity.

[0035] Further, a receiving step 1011a for receiving the barb 4012 is provided at the bottom of the latch hole 1011 in this embodiment, so that the bottom of the barb 4012 is located above the bottom surface of the limiting platform 101, that is, to prevent the barb 4012 from exceeding the bottom surface of the limiting platform 101 and affecting the installation of other parts.

[0036] In this embodiment, a skirt stop 402 is provided at the lower edge of the top piece 4, and an annular groove 1016 for cooperating with the skirt stop 402 is provided at the top of the limiting platform 101. It is worth noting that such a setting makes the gap between the top piece 4 and the outer cover 1 hidden in the annular groove 1016, preventing criminals from prying out the top piece 4 through the gap between the top piece 4 and the outer cover 1.

[0037] Reference Figures 8-11 , and at the same time combined with Figure 3 and Figure 4 , an installation hole 1012 is provided at the center of the limiting platform 101, two arc-shaped convex platforms 201 capable of cooperating with the installation hole 1012 are symmetrically provided at the top of the inner cover 2, an inverted buckle portion 202 is provided at the upper end of the arc-shaped convex platform 201, two support steps 1013 for cooperating with the inverted buckle portion 202 are provided at the top of the installation hole 1012, an installation notch 1014 is provided at one end of the support step 1013, and a rotation stopping portion 1015 for restricting the rotation of the arc-shaped convex platform 201 is provided at the other end of the support step 1013. During installation, the inner cover 2 is inserted into the outer cover 1 from bottom to top. After being inserted in place (the top of the inner cover 2 abuts against the bottom of the limiting platform 101), at this time, the arc-shaped convex platform 201 is located in the installation notch 1014 (as shown in Figure 5 ), and then the inner cover 2 is rotated to make the inverted buckle portion 202 buckle on the support step 1013 to form a cooperation (as shown in Figure 6 ), and the rotation stopping portion 1015 restricts the inner cover 2 from rotating towards the direction close to the rotation stopping portion 1015.

[0038] The side wall of the lining cover 3 cooperates with the inner side of the arc-shaped boss 201. The lining cover 3 is provided with an anti-rotation boss 301 placed in the installation notch 1014 to limit the undercut portion 202 from separating from the support step 1013. That is, the end of the arc-shaped boss 201 away from the above-mentioned anti-rotation portion 1015 is opposite to the anti-rotation boss 301. The anti-rotation boss 301 limits the inner cover 2 from rotating in the direction of separating from the support step 1013. In this way, after the inner cover 2 and the outer cover 1 are assembled, the lining cover 3 (such as Figure 7 As shown in the figure), the outer cover 1, the inner cover 2 and the lining cover 3 can be formed into a whole (that is, they can rotate together when the bottle cap is opened), and finally the lock buckle 401 of the top plate 4 is buckled into the lock hole 1011 on the limiting platform 101 (that is, the top plate 4 is connected to the outer cover 1), and the assembly can be completed. Compared with the prior art, the present invention adopts a physical structure to realize the assembly of the bottle cap, which makes the assembly more convenient and improves the assembly efficiency.

[0039] On the basis of the above, the top of the anti-rotation boss 301 is provided with an upper anti-warping step 3011, and the installation notch 1014 is provided with a lower anti-warping step 1014a near the upper anti-warping step 3011. Figure 7 For reference, the outer cover 1 is rotated counterclockwise to open the bottle cap. When the outer cover 1 is rotated counterclockwise, the outer cover 1 first rotates a certain angle relative to the lining cover 3. After the lower anti-warp step 1014a on the outer cover 1 rotates to above the upper anti-warp step 3011 on the lining cover 3, the outer cover 1, inner cover 2, and lining cover 3 are rotated together, causing the inner cover 2 to move upward relative to the inner cover, thereby opening the bottle cap. During the bottle cap opening process, the lower anti-warp step 1014a presses above the upper anti-warp step 3011, preventing the lining cover 3 from tilting upward due to torque.

[0040] In addition, it is worth mentioning that the arrangement of the lining cover 3 provides support for the inner side of the arc-shaped boss 201, thereby preventing the arc-shaped boss 201 from deforming inwards and causing the undercut portion 202 to separate from the support step 1013 when the bottle cap is opened by rotating the outer cover 1 or when the outer cover 1 is violently pulled up by criminals.

[0041] In this embodiment, the top of the lining cover 3 is provided with a blind hole 302, within which a reinforcing rib 303 is disposed. Furthermore, the reinforcing rib 303 is integrally formed with the lining cover 3. The number of reinforcing ribs 303 is not limited, as long as it ensures the structural strength of the lining cover 3 (enabling reliable support for the inner side of the arc-shaped boss 201). It should be noted that the blind hole 302 in the top of the lining cover 3 in this embodiment is merely an option to reduce weight. In other embodiments, the blind hole 302 may be omitted.

[0042] On the basis that the blind hole 302 and the reinforcing rib 303 are provided on the lining cover 3, two arc-shaped retaining platforms 403 symmetrical about the axis are provided at the bottom of the top sheet 4 in this embodiment. The outer side of the arc-shaped retaining platform 403 is matched with the blind hole 302. With such a setting, the arc-shaped retaining platform 403 can play a role in preventing the lining cover 3 from rotating.

[0043] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
