Abstract: A metal closure having multiple thread engaging lugs configured to decrease the pressure exerted by the closure lugs on the neck of a container is provided. In various embodiments, the metal closure comprises a top wall, a skirt extending downward from a peripheral edge of the top wall, a lower edge included on the skirt, and a plurality of lugs formed at the lower edge of the skirt. Pressure may be decreased by the closure having more lugs and/or larger lugs than other metal closures. The closure is provided with a gasket configured to provide enhanced sealing properties when the closure is secured to a container.

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 that includes a top panel and a skirt extending downwardly from a peripheral edge of the top panel is provided. The skirt terminates in a plurality of spaced thread engagement flanges for engaging the thread of the neck of a container. The closure includes a polymer-filled channel which connects the top panel to the skirt. When engaged with the threaded neck of a container, the neck is forced into the channel and engaged by the polymer so that the channel and polymer provide lateral rigidity to the neck. This rigidity prevents the neck from deflecting from the forces resulting between the threads and thread engagement lugs when the forces therebetween are increased to the level required to adequately seal the closure to the container.
