Abstract
Disclosed is an assembly of an elongated container and a plug therefor. The container has defined therein a receiving space for contents, an opening through which the contents are filled into the receiving space and discharged therefrom, and an annular ridge formed at a location spaced from the opening toward the receiving space a predetermined distance. The annular ridge defines a throat having a circumferentially continuous, planar sealing surface extending substantially longitudinally of the container a predetermined distance. The plug is threadedly engageable with the container so as to open and close the opening by axial one end of the plug. An annular resilient sealing member carried on the other axial end of the plug is in sealing contact with the planar sealing surface with the opening being closed by the axial one end of the plug threadedly engaged with the container.
