AI Technical Summary

Technical Problem

Traditional food containers pose a risk of bursting or deforming when microwaved because their airtight seal prevents the release of internal pressure.

Method used

A pressure-relief food container is designed. By setting a pressure relief port in the first container assembly or by utilizing the cooperation between the first container assembly and the lid assembly to form a pressure relief space, the steam pressure can be released in a timely manner. A multi-layer structure and multiple pressure relief ports work together to regulate the pressure.

Benefits of technology

It effectively prevents the food container from deforming or bursting due to excessive internal pressure, improves heating safety and versatility, and is suitable for microwave ovens and other environments where internal pressure needs to be controlled.
