Title: The Innovative Contributions of Toshihiro Takai

Introduction

Toshihiro Takai is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of thermoforming technology, holding a total of 6 patents. His work has advanced the methods and applications of thermoplastic resin processing.

Latest Patents

Among his latest patents, Takai has developed a thermoforming process that includes a unique apparatus featuring a female die and a movable plug. This apparatus is designed for thermoforming a softened thermoplastic resin sheet. The female die consists of a bowl-shaped recess that communicates with a bottom opening, forming the bottom wall and the outer and inner walls of the rim. The process involves thrusting the softened thermoplastic resin sheet by the plug while the bottom plate is held at a first stop position. This allows the resin sheet to contact the inner surface of the bowl-shaped recess, ultimately forming a rim as the bottom plate moves to a second stop position.

Another significant invention is a bowl-shaped container made from a thermoplastic resin sheet. This container features a hollow rim formed by folding the resin sheet into a bag shape and welding the sides. The body of the container is designed with a plurality of outwardly protruding ribs, enhancing its structural integrity without any slit-like recesses on the inner circumferential face.
