AI Technical Summary
Welding defects in existing pressure vessel valve cups may cause gaskets to fall off, posing a safety risk to users. Furthermore, existing snap-fit fixing methods require complex molds and large parts, resulting in high manufacturing costs.
Design a valve cup whose bottom wall includes a truncated conical outer periphery, an inner surface for fixing the valve body, an outer surface that can be made of metal, a support edge that can be tightly fitted to the housing by an expansion tube method, an edge at the central opening that is folded to form a rolled edge to prevent residual product from contacting, and a laminate structure of a polymer inner layer and a metal outer layer.
It achieves safe and reliable valve fixing, reduces manufacturing costs, avoids the risk of parts ejection, simplifies mold requirements, and is suitable for the recycling and reuse of aerosol generators.
