Abstract: A closure having a liner is provided. The liner forms one or more venting recesses that facilitate relieving pressure from a container to which the closure is affixed. In embodiments the liner extends from an outer surface of an annular wall through an outer disc of the liner.

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.

Abstract: A composite closure which includes an improved sealing gasket material and shape. The Closure includes an end panel that is received in a circular plastic fitment having a central opening therein defined by an inwardly extending flange which over-lies in an outer periphery of the end panel and an integral skirt downwardly depending from the flange. The fitment includes an inwardly extending circumferential bead or bead segments which include a substantially non-deformable flat vertical surfaces that are substantially parallel to the axis of the closure and axially positioned to contact the radial outer-most edge of the end panel when the closure is fully applied to a container. The sealing gasket has the shape of an annulus with a particular cross-section and formed from a PVC free material.

Abstract: A closure with a top panel, a skirt extending downward and away from the top panel, frangible connections that connect the skirt to a tamper band. The frangible connections provide a visual indication, when broken, that the closure has been opened. The tamper band includes a sidewall coupled to the frangible connections, the sidewall including a recess in which a pivotable engagement structure is displaced while the closure is applied to a container.
