Abstract
A hermetically sealed recloseable container is provided in which the closure is formed from a thermoplastic ring and an independent sheet-form member which is bonded to the ring and the upper end of the container such that when the closure is removed the sheet-form member will remain integral with the ring to provide a closure useful for reclosing the container. The method of forming such a sealed container is also provided.
