Crown cork

The firm still survives, producing many forms of packaging.[2] Crown corks are collected by people around the world who admire the variety of designs and relative ease of storage.[3][4] Collectors tend to prefer the term "crown cap" over "cork".[citation needed] The Budweiser brand often uses the crown shape of the cap to accentuate its "king of beers" strapline.This article about an item of drinkware or tool used in preparation or serving of drink is a stub.
