ABSTRACT:
A sealed container comprises a cylindrical jacket closed at opposite ends by closure pieces welded to the jacket. One closure piece forms a lid having an outlet opening pre-sealed by a tear-off tab. The lid includes a skirt projecting into the jacket, and a gas vent opening which is open during the installation of the closure pieces to vent displaced gas, and is thereafter closed by securing an end of the tear-off tab thereover, or by deforming the lid material, or by placing a drop of hardenable plastic in the vent opening.
