Abstract
A liquid dispensing method and system for dispensing from a container including an outer container and an inner container, a portion of the inner container occupied by the liquid, a remainder of the inner container occupied by a headspace gas. The system includes a probe having a flow passage therein and a gas passage communicating between the interior of the inner container and an exterior of the outer container. Fluid (such as air or nitrogen) is caused to flow under pressure into a space between inner walls of the outer container and the inner container to force the headspace gas out of the inner container via the gas passage and to force liquid out of the inner container through the flow passage in the probe to a manufacturing process.

12. A system for dispensing liquid to a manufacturing process from a container including an outer container and an inner container, the inner container occupied by the liquid and a headspace gas, the system comprising:
-
a probe insertable into the inner container, the probe having a flow passage therein;
a gas passage communicating between the interior of the inner container and an exterior of the outer container;
means for forcing the headspace gas out of the inner container via the gas passage to a headspace gas drain and for forcing liquid out of the inner container through the flow passage in the probe to the manufacturing process. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A liquid handling system comprising:
-
a container which comprises;
an outer container;
an inner container having an interior; and
wherein a portion of the inner container is occupied by the liquid, and a remainder of the inner container is occupied by a headspace gas;
a connector attachable to the container, the connector including a probe insertable into the inner container and having a flow passage therein, the connector further including a gas passage communicating between the interior of the inner container and an exterior of the outer container; and
a fluid air source in fluid communication with a space between inner walls of the outer container and the inner container for causing fluid under pressure to flow into the space between the inner walls of the outer container and the inner container to force the headspace gas out of the inner container via the gas passage to a headspace gas drain and to force liquid out of the inner container through the flow passage in the probe to the manufacturing process. - View Dependent Claims (22, 23)
