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.

A plastic container having an outlet comprising; a first cylindrical surface extending from an outer surface of a wall of said container partly through said wall, said cylindrical surface defining a first cylindrical opening with a first diameter; a flat annular surface within said wall integral with and essentially perpendicular to the first cylindrical surface; a second cylindrical surface integral with and essentially perpendicular to the flat annular surface, and essentially parallel to the first cylindrical surface; the second cylindrical surface being part of an inner collar extending from an inner surface of the container, the inner collar defining a second cylindrical opening having a second diameter less than the first diameter, the second cylindrical opening overlapping the first opening and extending into the container. A triple sealing outlet for a plastic container comprising an annular U-shaped channel positioned within a wall of the container for receiving a connector; the U-shaped channel comprising first, second and third sealing surfaces; the first sealing surface in the shape of an inner surface of a cylinder, extending from the outer wall of the container into the U-shaped channel, the inner surface defining a first cylindrical opening and being threaded for engaging and sealing a threaded outer surface; the second surface being essentially annular and essentially perpendicular to the first sealing surface, the second surface forming a stop for, and adapted to mate with a side surface of the connector for sealing the side surface; the third sealing surface being essentially parallel to the first sealing surface and essentially perpendicular to the second sealing surface, for engaging and sealing an inner surface of the connector; the third sealing surface being part of an inner collar extending from an inner wall of the container, the collar defining a second cylindrical opening for allowing communication between the connector and the interior of the container.
