Description

Technical Field

[0001] The invention relates to the technical field of anti-counterfeiting bottle caps, in particular to a bottle cap with secondary anti-counterfeiting function of a stainless steel sheet. Background Art

[0002] In the current market, the anti-counterfeiting problem of bottled goods has always been the focus of attention of manufacturers and consumers. With the development of technology, the anti-counterfeiting technology of bottle caps is also constantly improving. Traditional anti-counterfeiting methods of bottle caps include laser anti-counterfeiting, texture anti-counterfeiting, holographic anti-counterfeiting, etc., but these methods are often easy to imitate and difficult to identify in actual use, which brings many inconveniences to consumers and manufacturers.

[0003] In order to improve the anti-counterfeiting performance of bottle caps, some technologies have begun to use metal materials, such as stainless steel sheets, as anti-counterfeiting elements. Stainless steel sheets are widely used in the anti-counterfeiting field due to their unique physical and chemical properties, such as corrosion resistance, wear resistance, and easy processing into specific shapes and patterns. By embedding or laminating stainless steel sheets in bottle caps and making specific anti-counterfeiting marks on stainless steel sheets, the anti-counterfeiting effect can be effectively improved.

[0004] However, the existing anti-counterfeiting technology of stainless steel sheets still has some limitations. The installation method of stainless steel sheets may not be strong enough and may easily fall off during transportation or use; the anti-counterfeiting mark is too simple and can be easily copied by high-precision counterfeiting technology.

[0005] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a bottle cap with secondary anti-counterfeiting of stainless steel sheets. Summary of the invention

[0006] The object of the present invention is to provide a bottle cap with a secondary anti-counterfeiting stainless steel sheet to solve the common problems raised in the above background technology.

[0010] As a preferred technical solution, the lower cover opening notch cooperates with the upper cover opening protrusion, and the lower cover opening protrusion cooperates with the upper cover opening notch.

[0011] As a preferred technical solution, the outer wall of the stainless steel ring is provided with a plurality of groups of stainless steel spring sheets, and the stainless steel spring sheets cooperate with the edge of the inner sleeve to achieve anti-counterfeiting.

[0012] As a preferred technical solution, the glass bead is located between the lower part of the inner plug and the upper part of the inner plug, and its function is to seal the bottle mouth to prevent liquid leakage. The matching design of the valve core and the upper part of the inner plug ensures that when the bottle cap is opened, the valve core can move with the upper part of the inner plug, thereby opening the passage of the bottle mouth.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0021] See also Figure 1 and Figure 2 As shown, the present invention provides a technical solution for a bottle cap with secondary anti-counterfeiting of stainless steel sheet: it includes a bottle body 1, and the bottle mouth 1 is the opening part of the bottled goods, which is used to connect the bottle cap. The lower sleeve 2 is a component installed on the outside of the bottle mouth 1, which is used to fix the entire bottle cap structure. The top edge of the lower sleeve 2 is provided with a lower sleeve opening notch 21, and the adjacent side is provided with a lower sleeve opening convex block 22. The limit ring 3 is arranged in the lower sleeve 2, which is used to limit the movement range of the inner plug 4. The inner plug 4 is composed of an inner plug lower part 41 and an inner plug upper part 42. The inner plug lower part 41 extends into the lower sleeve 2, and the inner plug upper part 42 cooperates with the valve core 7. The stainless steel ring 5 is arranged on the outer side of the inner plug lower part 41 for secondary anti-counterfeiting. The outer wall of the stainless steel ring 5 is provided with multiple groups of stainless steel springs 51, which cooperate with the edge of the inner sleeve 8 to achieve the anti-counterfeiting function. The glass beads 6 are located between the inner plug lower part 41 and the inner plug upper part 42, and their function is to seal the bottle mouth 1 to prevent liquid leakage.

[0022] The valve core 7 is arranged in the inner sleeve 8, extends into the inner plug upper part 42, and is designed to cooperate with the inner plug upper part 42 to ensure that when the bottle cap is opened, the valve core 7 can move with the inner plug upper part 42, thereby opening the passage of the bottle mouth 1. The inner sleeve 8 is arranged above the lower sleeve 2, and a limit ring 3 is arranged in the inner sleeve 8. A threaded portion 81 is arranged on the outer wall of the upper part of the inner sleeve 8. The middle cover 9 is threadedly connected to the threaded portion 81, and an inner cover 10 is arranged above the middle cover 9.

[0023] The inner cover 10 is embedded in the middle cover 9, and a plug post 101 is provided at the bottom of the inner cover 10, and the plug post 101 is inserted into the valve core 7. The upper cover 11 is sleeved on the outside of the lower cover 2, and an upper cover opening protrusion 112 is provided at the bottom edge of the upper cover 11, and an upper cover opening notch 111 is provided on the adjacent side.
