ABSTRACT:
A package, especially for granular, powdered or fluid product, includes a container with a spout extending upward and inward from a threaded neck and then flaring outward to terminate in a circular rim forming a wide mouth container opening. A closure as an end wall coextensive with the container rim in a skirt curving downward and outward with threads formed on an inner surface at a cylindrical lower end. Sealing elements include an annular sealing flange extending downward and inward from the end wall and having an outer sealing surface which seals against the inner surface of the flared portion of the container. An upper portion of the inner surface of the skirt formed by an annular rib extends downwardly and outwardly from the end wall to form an upwardly converging gap into which the flared portion is wedged as the closure is applied to the container. A second seal is formed by an annular bead on the inner surface of the cylindrical lower portion of the skirt above the closure threads which engages a cylindrical surface on the container above the container threads and below the spout. A plurality of circumferencially spaced ribs extend radially inward and axially along the inner surface of the skirt to guide out of round container rims into the sealing gap.
