Abstract
Disclosed is a metal bottle seal that is disposed on the curl of the metal bottle. The bottle seal may be held in place by crimping of the curl. In addition, adhesive may be used to hold the bottle seal on the curl. Adhesives can be used that fill discontinuities that may exist in the curl as a result of substantial drawing and ironing of the metal. Further, the metal bottle seal can be made of a material or laminated with a material that is soft enough to fill the discontinuities. The seal can be preformed as a continuous annulus for easy application to the top of the metal bottle. The metal bottle seal can also be used in conjunction with a cap seal to ensure an adequate and reliable seal.
