A sealed airtight container 12 and a method for forming the same produces an increased resistance between the seal and a flange 22 on the container to pressure differences between the inside of the container and the outside environment. Thecontainer 12 includes a body having a hollow interior with sidewalls, a bottom, and having a planar opening 21 at one end. The opening in the hollow interior is surrounded by an outwardly extending flange 22. A multi-layer peelable cover 14,16,18 is sealed to the flange 22 surrounding the opening. The cover and the flange are deformed towards the bottom of the container from the plane of the opening to be sealed.
