1. A container for holding liquid chemicals comprising:
- an outer container having a mouth;
an inner container having a port;
means for coupling the port to the mouth;
a closure coupled to the mouth, the closure having an aperture and a first gas passageway therethrough, the first gas passageway in communication with an outside of the inner container;
a key code ring removably supported at an upper end of the closure;
a connector for coupling with the closure, the connector having a bottom end and a second gas passageway therethrough in communication with a gas source; and
a key pattern connected to the bottom end of the connector, the key pattern configured to mate with the key code ring so as to form a manifold in communication with the first gas passageway and the second gas passageway.

Abstract
A system for handling high purity liquid chemicals has an outer container with a mouth. A closure holding a key code ring is coupled to the mouth. The system also has a connector for coupling with the closure. The connector has a key pattern configured to mate with the key code ring in the closure. The connector is connected to a manufacturing process and coupled to the closure such that liquid chemicals can be dispensed from the container to the manufacturing process.

11. A method of insuring proper connection of chemicals in a production process, the method comprising:
-
providing a flexible bag having an interior for holding liquid, the bag having a port in communication with the interior; placing the flexible bag within an outer container having a mouth and connecting the port to the mouth; attaching a closure having a top end over the mouth, the closure having a first liquid passageway and a first gas passageway therethrough; attaching a key code ring to the closure top end; providing a connector having a second gas passageway and a fluid probe defining a second liquid passageway, the second liquid passageway in communication with the production process; attaching a key pattern to the connector circumscribing the fluid probe, the key pattern configured to mate with the key code ring so as to form a manifold in communication with the first gas passageway and the second gas passageway; inserting the fluid probe into the first fluid passageway and coupling the connector to the closure such that if the key code ring mates with the key pattern a manifold is formed thereby which places the first gas passageway in communication with the second gas passageway, and if the key code ring does not mate with the key pattern the first gas passageway is in communication with the atmosphere; and connecting the gas passageway to a compressed gas source.

12. A container for holding liquid chemicals comprising:
-
an outer container having a mouth; an inner container having a port; means for coupling the port to the mouth; a closure coupled to the mouth, the closure having an aperture therethrough; a key code ring having a bottom side, supported at an upper end of the closure, the bottom side having a groove therein circumscribing a central aperture of the key code ring and in communication with a passageway in the closure; a connector for coupling with the closure, the connector having a bottom end; and a key pattern connected to the bottom end of the connector, the key pattern configured to mate with the key code ring. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

13. A container for holding liquid chemicals, the container comprising:
-
an outer container having a mouth; an inner container having a port, the port coupled to the mouth; a closure coupled to the mouth, the closure having an aperture therethrough, the aperture in communication with the port of the inner container; a key code ring supported at an upper end of the closure; a connector having a probe extending from a bottom end thereof, the connector coupled to the closure such that the probe of the connector extends through the aperture of the closure; and a key pattern connected to the bottom end of the connector, the key pattern configured to mate with the key code ring such that the probe engages the port of the inner container. - View Dependent Claims (14, 15)
