Decorative preform for synthetic resin container manufacturing
The patent US12043443B2 describes a preform designed for the production of synthetic resin containers through blow molding. The preform features a bottomed cylindrical main body with an open mouth portion and includes a covering layer that encases the main body, leaving a section of the mouth portion exposed. Notably, the covering layer covers the lower surface of a neck ring located at the mouth's lower end, extending annularly around its circumference. The design ensures that at least part of the covering layer protrudes beyond the neck ring's peripheral edge, while it does not extend above the neck ring's lower surface. Additionally, the covering layer can be made from a thermoplastic resin that is incompatible with the resin used for the preform main body.
Furthermore, the patent outlines the resulting synthetic resin container produced from the preform, which incorporates a decorative layer that mirrors the uneven shape of the container's main body. This decorative layer also covers the lower surface of the neck ring and protrudes similarly to the covering layer of the preform. The claims emphasize that neither the covering layer nor the decorative layer covers the upper surface of the neck ring, ensuring a specific aesthetic and functional design. The inclusion of a cutout portion in the neck ring allows for the exposure of the covering layer, further enhancing the design's uniqueness. Overall, the patent presents a novel approach to the design and manufacturing of synthetic resin containers, focusing on both structural integrity and decorative appeal.
