A recently granted patent (Publication Number: US11912458B2) discloses a plastic container manufactured from a preform with a high mass share of polyester and various additives. The container features a unique design with a container neck, shoulder, body, and base exclusively reshaped through a 2-stage stretch blow molding method. The polyester used is a copolyester containing specific monomers like cyclohexanedimethanol (CHDM), monoethylene glycol (MEG), terephthalic acid (TPA), and isophthalic acid (IPA). Additionally, the container body and shoulder may have sharp edges with a radius of less than 0.5 mm, enhancing its structural integrity.

Furthermore, the patent outlines specific characteristics of the copolyester used in the plastic container, including intrinsic viscosity, density, and composition of diol and dicarboxylic acid shares. The method of manufacturing the plastic container involves stretching the preform body during blow molding, shaping the container components according to the inner geometry of the blow mold cavity. The sharp edges on the container are designed to be less than 0.5 mm, ensuring precision in the manufacturing process. Overall, the patent provides detailed insights into the composition, design, and manufacturing method of a unique plastic container with specific structural features and material properties.
