Bursting ejection double anti-forge bottle cap

Abstract

The invention relates to a blasting-off and ejection type secondary anti-fake cover and belongs to the technology field of fluid container protection and repeated use prevention of the seal cap manufacture. The cover mainly comprises a lower sleeve (3), an upper cover (1) and a safety ring (2) sleeved on the upper part of the lower sleeve (3) and an inner connecting cover (4) and a middle sleeve (5) arranged inside the inner sleeve (3) and engaged through screw threads; wherein, an inner screw thread (8) and a fixed port (10) are arranged in the upper cover (1); a blasting-off port (12), a blasting-off tooth (13) and a fixed muscle (11) are arranged on the safety ring (2); an ejection sheet (14), an external screw thread (15), a blasting-off tooth socket (17) and a rotary retaining tooth socket (16) are arranged on the lower sleeve (3); a wine outlet (19) and a rotary retaining tooth (21) are arranged on the inner connecting cover. By combining the structures of blasting-off and ejection into one, both the safety ring and the ejection sheet strength the secondary anti-fake effect, thus improving reliability and practicality of the product and leading to a more outstanding anti-fake effect.

Description

technical field [0001] The invention relates to a burst ejection type secondary anti-counterfeit cover, which belongs to the technical field of sealing cap manufacturing for protecting liquid containers and preventing repeated use. Background technique [0002] The existing anti-counterfeiting wine bottle caps generally take measures to complicate the structural design of wine bottle caps and increase the difficulty of anti-counterfeiting. , lower sleeve, etc., through the rotation of the upper cover and the inner cover relative to the middle cover, the inner cover is unscrewed, so that the wine in the bottle flows out from the upper port of the middle cover. From the perspective of structural form, there are mainly the following defects: 1. The twist-off ring is integrated with the upper cover, and the twist-off ring is easily scrapped if it is slightly careless during processing, which brings great difficulty to product processing while increasing the process. . 2. With ...

Problems solved by technology

From the perspective of structural form, there are mainly the following defects: 1. The twist-off ring is integrated with the upper cover, and the twist-off ring is easily scrapped if it is slightly careless during processing, which brings great difficulty to product processing while increasing the process.

2. Using fusion welding process, the welding waste and powder generated during assembly are easy to be brought into the wine bottle, causing pollution to the wine

3. Due to the complex processing and assembly process, it is still difficult to achieve the desired effect, and it is easy to cause damage when the wine bottle cap is installed on the bottle mouth, resulting in the overall scrapping of the cap and the bottle
