Title: Innovations by Hugh C Urmston
Introduction
Hugh C Urmston is a notable inventor based in Sparta, NJ (US). He has made significant contributions to the field of thermoplastic closures, holding a total of 3 patents. His work focuses on enhancing the functionality and efficiency of closures used in various applications.
Latest Patents
Urmston's latest patents include a "Threaded thermoplastic closure with vent slot" and a "Male core for forming vent slots in a thermoplastic closure." Both inventions feature a male core designed to be mateable with a female mold for forming vent slots in thermoplastic closures. The male core comprises a cylindrical member with an end surface that forms an underside top surface and an inside surface of a downwardly depending skirt on the closure. A helical groove is formed around the periphery of the cylindrical member, creating a thread on the inside surface of the skirt. Additionally, at least one integral rib is formed in the cylindrical member, arranged parallel to the longitudinal axis of the closure. This rib forms a vent slot in the closure that traverses the thread. The convoluted surfaces on the cylindrical member extend from each side surface of the rib to the bottom of adjacent helical grooves. These surfaces provide smooth radii on the ends of the threads adjacent to the vent slot, facilitating the axial stripping of the closure from the male core without deforming the threads into the vent slot. This design enhances the passage of pressurized gas through the vent slot to the atmosphere as the closure is removed from a container.
