These metal tooth crown bottle caps are attractive. The small flat objects are not only functional as they are meant to grip the flange on the bottle neck but also serve as surfaces for various logos and brand names. They were the most common types of bottle caps before the arrival of the screw caps. The early crown caps came with a cork seal and a paper backing. This was later modified to become a cap that could be twisted and with the help of an opener. The particular trade marks and names of popular drinks on the caps reveal the types of beverages that were consumed during this period.
