AI Technical Summary

Technical Problem

Existing waste containers for infectious waste require autoclave sterilization, but current designs compromise airtightness, increase contamination risk, and have unpredictable heat shrinkage issues, making them incompatible with safety standards.

Method used

A filling lid made of a mixture of thermoplastic elastomer and amorphous thermoplastic materials, with a deformable design and locking mechanism, allowing secure closure and sterilization without compromising airtightness, using a bonding material that liquefies at a controlled temperature.

Benefits of technology

Ensures effective sterilization of infectious waste while maintaining airtightness and adhering to safety standards, reducing contamination risk and ensuring complete steam penetration during autoclave treatment.
