Latest Patents
John W Ashley holds a patent for a "Method for manufacturing an ampule." This patent describes a method and mold for creating an ampule specifically designed for needleless or jet injector devices. The process involves guiding the tip of a core pin into a clearance hole that is large enough to prevent contact with the mold cavity. Plastic is injected into the mold, flowing into the space between the core pin tip and the clearance hole, which forms a vestigial nozzle pilot cylinder around the ampule nozzle. After the ampule is removed from the mold, the vestigial nozzle pilot cylinder is detached, resulting in a finished ampule. The design allows for a core pin tip made of drawn wire or a separately replaceable component, and the nozzle of the ampule is cast in place, ensuring precision in the final product.
