Zusammenfassung:A closure 10 that includes a top panel 12 and a skirt 18 extending downwardly from a peripheral edge of the top panel is provided. The skirt terminates in a plurality of spaced thread engagement flanges 20 for engaging the thread 38 of the neck 30 of a container 11. The closure includes a polymer-filled channel 14 which connects the top panel to the skirt. When engaged with the threaded neck 30 of a container, the neck is forced into the channel 14 and engaged by the polymer 40 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.
