Abstract
A container adapted to contain a beverage or other goods is provided with an easy open top by a disk juxtaposed to a hole in the container lid and welded to the container lid by a ring weld circumscribing the hole. Access to the contents of the container is attained by pushing the disk into the container whereby the disk tears along the weld and does not separate from the lid.
