Appl. No.:

8/950695

Inventors:

James D. Lowery - Jackson MS

International Classification:

B01D 17025

US Classification:

210800

Abstract:

A device for adapting a liquid container to enable separation and selective dispensation of two or more immiscible liquids of different densities from the container. The device comprises (a) a first liquid conduit adapted at one end for detachable attachment to the container, whereby the first conduit and the interior of the container may be placed in fluid communication with one another, (b) at least one wall forming a liquid reservoir, the other end of the first conduit opening into the reservoir at a first liquid passage to place the interior of the container in liquid communication with the reservoir, and (c) a second liquid conduit which at one end opens into the reservoir at a second liquid passage and at the other free end opens to an exterior of the container, thereby placing the reservoir in liquid communication with the exterior, wherein the first and second liquid passages are spaced apart from one another and disposed relative to the reservoir such that liquids from the container can form separate phases in the reservoir when dispensed from the container and through the first conduit and the liquid(s) of lesser density or densities can be dispensed from the reservoir through the second liquid passage while the liquid(s) of greater density or densities remain in the reservoir. Methods of separating and selectively dispensing two or more immiscible liquids of different densities from a container, as well as methods for adapting a container to enable separation and selective dispensation of two or more immiscible liquids of different densities from the container are also disclosed.

Abstract:

Described are novel containers adapted to separate and dispense two or more fluids of different densities, and novel methods of selectively separating and dispensing two or more fluids of different densities. In one embodiment, the container of this invention comprises (a) a top container portion defining at least one aperture through which fluid may flow, (b) a bottom container portion, (c) a phase separator between the top container portion and the bottom container portion, the separator and the top container portion defining an upper fluid chamber, the separator and the bottom container portion defining a lower fluid chamber, the chambers being in fluid communication with one another, and (d) a conduit extending from the lower chamber to the exterior of the container in such a way that, when the container is positioned for dispensation of fluid through the aperture, the fluid of greater density is substantially trapped within the lower chamber to permit concurrent separation of the liquids and dispensation of either the fluid of lesser density from the upper fluid chamber or the fluid of greater density from the lower fluid chamber.
