Abstract
An improved hermetically sealed composite container formed by double-seaming a pair of compounded metal ends to extended length flanges on the opposite ends of a can body so that the compound is bonded to an inner liner on the can body to provide an effective seal. The compound material is placed in the seaming panel and curl area of the metal ends so as to provide a more extensive seal area when the metal ends are double-seamed with the extended flanges on the can body. The extended length flanges provide a considerably greater contact area between the can body inner liner and the metal ends when the metal ends are double-seamed to the can body.
