AI Technical Summary
The sealing strip structure at the mouth of existing rust-proof bags is prone to cracking, resulting in decreased sealing performance and inability to effectively prevent rust for a long time.
The bag employs a threaded connection structure consisting of a stepped collar, an outer collar, and a cap. By setting threads in different parts of the stepped collar, combined with elastic rubber gaskets and pressure plates, multiple seals are achieved for the bag body, ensuring the stability of the bag opening.
This improves the sealing stability of the rust-proof bag, ensuring that rust-proof items maintain good rust-proof performance over a long period of time.

[0002] Rustproof bags are widely used in long-distance transportation of metal products to protect the metal products. Generally, the rustproof bags are made of gas-phase rustproof plastic bags. After the metal products to be rustproof are placed in the rustproof bags and sealed, the VCI contained in the bags starts to sublimate and emit rustproof gas, which diffuses and penetrates to the surface of the rustproofed objects and is adsorbed thereon to form a monomolecular thick dense protective film layer, thereby preventing the rustproofed objects from contacting various factors that induce rust and effectively preventing rust from occurring.
[0003] However, the mouth of some existing rustproof bags is provided with a press-type sealing strip structure. With long-term storage, the sealing strip structure is prone to cracking at some positions, which reduces the sealing performance of the rustproof bag and prevents it from normally preventing rust.
