Introduction

Shunsaku Hirata is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of materials science, particularly in the development of polyester vessels. With a total of six patents to his name, Hirata's work focuses on enhancing the properties and manufacturing processes of thermoplastic resins.

Latest Patents

One of Hirata's latest patents is for a biaxially drawn polyester vessel that exhibits resistance to heat distortion. This invention is based on the discovery that a multi-layer blow-formed body, when heat-treated and cooled, can maintain its shape due to the gas-barrier resin acting as a heat-insulating layer. The process allows for high manufacturing speeds and reduced steps, making it efficient for producing containers with excellent thermal contraction and gas-barrier properties.

Another significant patent involves a molded container with a wall composed of an oriented resin blend. This container features a thermoplastic resin that is oriented in at least one direction, ensuring enhanced performance. The blend consists of multiple melt-extrudable thermoplastic resins, each with specific solubility parameters, which contribute to the container's overall strength and thermal shrinkability.
