Title: Innovations by Sheldon L Wilde
Introduction
Sheldon L Wilde is a notable inventor based in Crawfordsville, IN (US). He has made significant contributions to the field of plastic closures, holding a total of 12 patents. His innovative designs focus on enhancing the functionality and security of container closures.
Latest Patents
One of his latest patents is the "Tamper-indicating plastic closure." This invention features a design that allows for mechanical interference with the annular locking ring of an associated container. The closure includes a top wall portion and a depending skirt portion, with a circular pilfer band that is partially detachably connected to the skirt by circumferentially spaced fracturable bridges. The internal, annular interference lip of the pilfer band is skewed relative to the vertical axis, which helps minimize stress on the fracturable bridges during closure application and removal.
Another significant patent is the "Plastic closure with structural thread formation." This closure is designed for containers with externally threaded necks. It includes an internal structural thread formation that comprises a helical thread ramp portion for load-bearing engagement with the container's thread. The design also features reinforcing gussets to enhance the thread ramp's strength, facilitating high-speed molding and reducing the amount of plastic material needed.
