[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] In scenarios where there is a need to handle the contents of a container, a through-hole is typically made in the bottle cap to facilitate pouring or suctioning out the solution. However, the presence of this through-hole generally compromises the seal of the cap. Current technologies often address this by applying additional sealing material, but the sealing performance is generally poor, and the cap cannot be closed securely after opening.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.

These terms are primarily used to distinguish one component from another, or one signal from another.

[0032] Please see Figure 1-4 This embodiment provides a multifunctional bottle cap for attaching to an annular bottle body 1. The outer wall of the bottle body 1 has a first external thread 11. The multifunctional bottle cap includes:

[0033] The inner cover 2 has a first internal thread 21 whose size and position match the first external thread 11 on its inner wall, and a second external thread 22 and a limiting groove 23 on its outer wall. The inner cover 2 also has a through hole 24.

[0034] Outer cover 3, which is fitted onto inner cover 2, and the inner wall of outer cover 3 is provided with a second internal thread 31 whose size and position match the second external thread 22. The outer cover 3 is connected with an anti-theft ring 32, which is radially engaged in the limiting groove 23.

[0035] The multifunctional bottle cap also includes a gasket 4, which is clamped between the inner cap 2 and the bottle mouth of the bottle body 1. The through holes 24 of the inner cap 2 are located at the position covered by the gasket 4, and there are multiple through holes 24.

[0036] Based on the above embodiments, when the operator needs to use it, firstly, the outer cover 3 is rotated, causing the second internal thread 31 of the outer cover 3 to move outward relative to the second external thread 22 of the inner cover 2. The outer cover 3 moves outward from the bottle opening, while the anti-theft ring 32 is embedded in the limiting groove 23 of the inner cover 2. Therefore, it is pulled by the outer cover 3 and the limiting groove 23 until it reaches the limit position, at which point the node connecting it to the outer cover 3 breaks, and the anti-theft ring 32 separates. Therefore, the operator can determine that it is in the open state. Thus, the operator can then perform corresponding processing on the inner cover 2. The processing method can be as shown in the following two embodiments as needed:

[0037] In one embodiment, after the outer cover 3 is completely removed, the inner cover 2 is further rotated so that the first internal thread 21 and the first external thread 11 of the bottle body 1 are misaligned, so that the inner cover 2 is completely separated from the bottle body 1. At this time, the maximum opening of the bottle body 1 can be obtained.

[0038] In another embodiment, the operator can retain the inner cover 2 and drain or suck out the liquid inside through the through hole 24 on the inner cover 2 to achieve the transfer of liquid in the small-diameter bottle 1.

[0039] In this invention, a good sealing protection can be achieved by combining two nested outer caps 3 and inner caps 2, and the position and size of the through holes 24 can be flexibly set. Specifically, the inner cap 2 provides the first layer of protection for the bottle body 1, the through holes 24 on the inner cap 2 allows for material dispensing, and the outer cap 3 isolates the inner cap 2 from the outside, achieving final protection. Furthermore, the number of through holes 24 on the inner cap 2 can be flexibly set, for example, to accommodate multiple material dispensing operations.

[0040] In short, because the outer cover 3 provides additional protection for the inner cover 2, the through hole 24 on the inner cover 2, which originally needed to be considered for sealing, now has more room to operate.

[0041] For example, in one embodiment, the number of through holes 24 is plurality of them. One of the through holes 24 is located at the center of the bottle cap, and the other plurality of through holes 24 are arranged at equal angles around the center of the bottle cap. Figure 2 As shown, this application can provide seven through holes 24, allowing material to be removed from the corresponding through holes 24 as needed. During material removal, the gasket 4 or other structures at the bottom of the corresponding through hole 24 can be punctured or opened, making it easier for operators to detect the number of times material has been removed.

[0042] Further, please see Figure 1 In fact, in this embodiment, the gasket 4 can be used to seal one side of the bottle body 1. Specifically, the gasket 4 tightly covers the bottle mouth of the bottle body 1. The gasket 4 can be made of a material with a certain elasticity, which undergoes elastic deformation under compression to achieve a better sealing effect.

[0043] Specifically, the inner wall of the inner cover 2 is provided with an annular groove 25, and the gasket 4 is embedded in the groove 25. The groove 25 is configured as a groove extending in an annular shape, and its size matches the thickness of the gasket 4. The gasket 4 can be installed in the groove in an embedded form, so that the groove 25 is filled with the gasket 4, which ensures sealing while facilitating installation.

[0044] Therefore, in the embodiment where the inner cap 2 is retained and the liquid inside is drained or drawn out through the through holes 24 to transfer liquid from the bottle 1 to a small diameter, the through holes 24 can be broken sequentially as needed. This allows the operator to visually see the number of broken through holes 24, enabling a clear record of the number of times liquid is extracted, thus providing better safety. In other words, the multi-functional bottle cap has a preset number of uses, and the number of through holes 24 is not less than this preset number of uses. For example, in one embodiment, if the bottle contains 500ml of liquid and generally requires 5 uses, with 100ml extracted each time, then five or six through holes 24 are needed.

[0045] The outer wall of the outer cover 3 is provided with raised anti-slip ridges 33, which extend in the direction in which the outer cover 32 is detached. In this embodiment, the number of anti-slip ridges 33 is set to six, and the width of each anti-slip ridge 33 is set to 4.7mm. Compared with the anti-slip ridges provided on a typical outer cover 3, the number of anti-slip ridges 33 in this embodiment is smaller and the thickness is greater, which is suitable for the design of larger-sized outer cover 32, and the mold opening cost is lower and it is easier to produce.

[0046] In this embodiment, the anti-theft ring 32 is integrally formed with the outer cap 3, and is located at the end of the outer cap 3. The anti-theft ring 32 primarily functions to determine whether the multi-functional bottle cap of the bottle 1 has been opened by checking whether it separates from the outer cap 3, thus assessing the safety of the liquid inside the container. The integral structure of the outer cap 3 and the anti-theft ring 32 facilitates production; the outer cap 3 and the anti-theft ring 32 are connected only by a cutting connection point, allowing for easy separation under external force.

[0047] The outer cover 3 and anti-theft ring 32, which are constructed in one piece, can be made of the same corrosion-resistant plastic material as the inner cover 2. The colors of the inner cover 2, anti-theft ring 32, and outer cover 3 can be differentiated as needed, which can more easily achieve a prominent security reminder effect.

[0048] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.
