Closure

摘要

A crown closure having a curled lower edge is described. The curled crown is typically formed from double reduced steel which is 35% thinner gauge than that used for conventional fluted crowns. The crown is also described in combination with a standard glass bottle. The curl of the crown tucks under the capping bead of the bottle so as to achieve standard pressure requirements. Added benefits of this configuration are not only the concealment of the edge of the closure but also the distinctive appearance of the product.
