ABSTRACT:
A triple sealing outlet for use in plastic containers comprises a first cylindrical surface, preferably threaded, extending from an outer wall of the container; a flat, annular surface perpendicular to the first surface and lying within the wall; and a second cylindrical surface of smaller diameter, parallel to the first surface and perpendicular to the flat annular surface, extending from an inner collar which is part of the inner wall of the container. These three surfaces are adapted to engage and mate with three corresponding surfaces of a connector, or of an appropriately designed valve, to provide fluid tight seals.
