Title: Tak Man Lee and His Sterilization Invention.

Introduction

Tak Man Lee is an inventor associated with Killara, Australia, and PepsiCo, Inc. His patent work addresses a practical challenge in sterilizing containers filled with both liquid and solid inclusions: preventing the solid particles from clumping together and obstructing sterilization.

Latest Patents

Lee is credited with 1 patent: “Prevention of Agglomeration of Particles During Sterilization Processes.” The invention describes a method and apparatus for hot-fill or cold-fill sterilization. It subjects a filled container to a sequence of changing orientations, typically alternating between approximately 60 degrees and 140 degrees from vertical for at least 30 seconds. This movement helps prevent solid inclusions from agglomerating, including near the closure, so the liquid can contact the container’s interior surfaces long enough to support sterilization. The apparatus conveys containers through the sequence of angles and includes an enclosure to keep them from falling off the conveying mechanism.

Career Highlights

Lee’s listed invention focuses on improving sterilization processes for containers that hold both liquids and solid pieces. By addressing particle agglomeration during processing, the method aims to help ensure that the container’s interior surfaces receive adequate contact with the sterilizing liquid.

Collaborations

Lee’s listed coworkers include Galo Cadena and David Bell. His company affiliation is PepsiCo, Inc.

Conclusion

Tak Man Lee’s patent describes a container-inversion approach designed to reduce particle agglomeration and support effective sterilization of packaged products.
