Abstract:
A closure includes a top panel and a corner section connecting an outer periphery of the top panel with a downwardly extending annular skirt. A plurality of gently curved ridges are spaced about the outer perimeter of the closure. The ridges generally extend from a lower portion of the skirt and around the corner section, with the upper ends of the ridges terminating proximate the top panel outer periphery. A plurality of knurls extend radially outwards from the midpoints of the ridges along the skirt of the closure. The configuration, arrangement, and spacing of the ridges and knurls about the closure provide an enhanced grip and feel, allowing for easier twist-off of the closure from a container. The closure may be used interchangeably with existing capping chucks used to apply conventional closures without requiring any modification to the capping chucks to apply the closures to containers during a capping process.
