Abstract
A method of making a package that includes the steps of blow molding a hollow plastic container, including blow molding a finish and a moil or dome that extends from the finish, and trimming the moil from the container finish so as to leave a conical flange extending inwardly and upwardly from the finish terminating in a smooth trimmed surface. A closure is provided having a base wall and a peripheral skirt. A liner is secured to the base wall within the skirt, and has a sealing surface spaced from the skirt. The closure is secured to the container finish in such a way that the container flange extending from the finish is deformed radially inwardly and axially downwardly by a peripheral portion of the liner so as to bring the trimmed surface of the container flange into abutment sealing engagement with the sealing surface of the liner. In various embodiments of the invention, the radially outwardly facing sealing surface on the liner is conical, convex, or formed by a hooked protrusion that extends axially from the liner.
