Bottom circumferential fracture and flange circumferential fracture of reinforced glass containers achieved through geometric feature design
By strengthening glass containers to create a specific geometric distribution of compression and tension, the problem of sterility damage during transportation and storage is solved, enabling rapid identification and handling of damaged containers and reducing recall and cost risks.

AI Technical Summary
Existing glass containers are prone to developing cracks that penetrate the wall thickness during transportation and storage, which can impair the sterility of the contents but do not lead to catastrophic packaging failure, resulting in recalls and increased costs.
By strengthening the glass container to create a compression and tension distribution with specific geometric characteristics, the crack propagation behavior is controlled, promoting the fracture morphology of bottom ring breakage or flange ring breakage, ensuring that the container cannot be used if sterility is compromised.
It enables rapid identification and handling of damaged glass containers based on their obvious fracture patterns, preventing contamination of contents and reducing recall and cost risks.
