摘要:
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.
