Abstract:
A bottle sealed with a crown cap that has a soft feel during removal of the crown cap from the bottle is provided. Such a bottle may include a body and a neck extending up from the body. The neck may include a threaded portion, and a crimped crown cap may be removeably affixed onto the threaded portion. The crimped crown cap may include a circular top member, and a skirt depending downwardly from a periphery of the top member. The skirt may include alternating flutes and lands that are configured such that recesses are formed in a majority of the flutes. Preferably a majority of the recesses contact the threaded portion of the bottle neck. Because of the recesses formed in the flutes, the crown cap may have a soft feel during removal of the crown cap from the bottle.
