Description

Technical Field

[0001] The utility model relates to the technical field of leak-proof covers, in particular to an environmentally friendly leak-proof cover. Background Art

[0002] When bottling emulsions or ointments, a leak-proof cap needs to be added between the screw cap and the bottle mouth to prevent leakage while ensuring product quality. However, the existing leak-proof cap has a simple structure and is just an inverted round cap. It has poor sealing performance, uses a lot of materials, and is not environmentally friendly. Therefore, an environmentally friendly leak-proof cap is proposed. Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] To this end, the technical solution adopted in this utility model is:

[0005] An environmentally friendly leak-proof cover comprises a round edge, wherein the inner side of the round edge is provided with multiple steps, the inner side of the multiple steps is provided with an anti-slip bevel, and the middle part of the anti-slip bevel is provided with an undercut step.

[0006] Preferably, the anti-slip bevel is formed by vacuum molding the middle part of the multi-step.

[0007] Preferably, anti-slip teeth are provided on the circumference of the anti-slip bevel.

[0008] Preferably, the diameter of the multiple steps is smaller than the diameter of the circular edge.

[0009] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0010] In the present invention, through vacuum forming, the material input is effectively reduced, the cost is reduced, and the plastic material is reduced, which has certain environmental protection significance. At the same time, the multi-step steps can increase the contact area between the multi-step steps and the bottle mouth after the cap is screwed on, thereby improving the sealing performance and avoiding leakage. The seal can also preserve the product for a longer time, thereby improving the practicality of the device. In addition, the inverted step set in the middle can be easily taken without the need for an additional handle, further reducing the amount of material used and achieving plastic reduction and cost reduction.

[0017] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0018] An environmentally friendly leak-proof cover provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0019] Example:

[0020] Combine Figure 1-4 As shown, the environmentally friendly leak-proof cover provided by the utility model includes a round edge 110, a multi-step step 120 is provided on the inner side of the round edge 110, the diameter of the multi-step step 120 is smaller than the diameter of the round edge 110, and an anti-slip bevel 130 is provided on the inner side of the multi-step step 120. The anti-slip bevel 130 is formed by vacuum molding in the middle part of the multi-step step 120, and anti-slip teeth are provided on the circumference of the anti-slip bevel 130. An undercut step 140 is provided in the middle part of the anti-slip bevel 130. The undercut step 140 does not need to rely on a single injection molding process, and is not limited to a single material. It can improve the limit of the material, optimize the process, reduce plastic and reduce costs.

[0021] Moreover, the green and environmentally friendly material design process can make the packaging simpler and more convenient while ensuring the existing functions.

[0022] Specifically, the anti-slip teeth on the anti-slip bevel 130 can play a certain anti-slip role when the anti-slip bevel 130 penetrates into the emulsion or paste, preventing the round edge 110 from rotating. At the same time, the multi-step steps 120 are fitted to the inner wall of the bottle mouth, increasing the sealing depth and effectively improving the sealing performance. In addition, compared with the 1mm thickness of the existing device, the present device can achieve a thickness of 0.3mm, greatly reducing the material consumption.

[0023] The working principle and usage process of the present invention are as follows: first, the device is formed by vacuum forming, then disinfected and sterilized, and then placed on the front-end process equipment of the automatic capping machine. The device is started to start the operation of the entire process. After the emulsion or paste is injected, the conveyor belt is transported to the position where the device is installed, and the device is buckled onto the bottle mouth. The multi-step steps 120 are used for positioning, and the anti-slip bevel 130 is used to prevent the round edge 110 from rotating. Then it runs to the capping area, and the pressure brought by the capping is used to firmly fix the device between the bottle mouth and the cap to avoid shaking. Finally, the device is packaged.

[0024] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
