AI Technical Summary
The sealing bowl of the existing aerosol can is prone to cracking during valve expansion, leading to seal failure and leakage of contents.
A crack-resistant structure, such as an annular groove or protrusion, is provided on the inner wall of the opening of the sealing bowl, and a sealing rib is provided on the outer circumference of the connecting part. The support structure prevents the bag opening from being squeezed and closed, thus improving the sealing performance.
It effectively prevents the sealing bowl from cracking during valve expansion, improves sealing performance, prevents leakage of contents, and ensures the airtightness and stable spraying of the aerosol can.
