Title: Howard F. DeFerrari: Innovator in Tamper-Evident Structures and Packaging Solutions
Introduction
Howard F. DeFerrari is a notable inventor based in Louisville, KY (US). He has made significant contributions to the field of packaging and tamper-evident technologies. With a total of 6 patents to his name, DeFerrari's work has had a considerable impact on product safety and integrity.
Latest Patents
One of DeFerrari's latest inventions is a tamper-evident structure. This innovative design features a laminated structure that exhibits an irreversible color change upon delamination. The laminate consists of at least two layers that generate color through light interference and absorption. The strength of attachment among the layers allows for uniform peeling, and an overlying flexible strip aids in this process. When the laminate is peeled apart, the generated color is irreversibly lost, providing clear evidence of tampering. This structure can be integrated into various closable products to enhance security.
Another significant patent involves a process for coating a packaging film with a transparent barrier coating. This process begins with a metal substrate, which is anodized to form a detachable anodic film. The packaging film is then attached to this anodic film, which forms a thin, dense oxide coating that acts as a barrier against oxygen and moisture. This invention is particularly useful for creating packaging films suitable for foodstuffs and other sensitive products.
