Manufacturing metallic containers with inwardly facing threads
A recently granted patent (Publication Number: US11897021B2) discloses an apparatus designed to seal a metallic container using a threaded closure. The apparatus consists of two tools - a first tool that applies a downward force to the threaded closure, elastically deforming it, and a second tool that forms container threads on the neck of the metallic container by pressing it against the closure threads. The first tool is specifically configured to contact the uppermost area of the threaded closure and alter the angle at which the extension projects from the closure body. The second tool, a thread roller, applies a force transversely to the longitudinal axis of the container to create container threads with peaks and valleys on the neck.
Furthermore, the apparatus includes features such as controlled movement and timing of the tools using cams and cam followers, the ability to bend the extension of the closure body, and the application of specific forces ranging from 1 pound to 300 pounds. The design allows for precise movement of the tools relative to the threaded closure and the metallic container, ensuring proper sealing of the container. The apparatus aims to provide a reliable and efficient method for sealing metallic containers with threaded closures, offering a unique approach to container sealing technology.
