Returnable and reusable, bag-in-drum fluid storage and dispensing container system
First Claim
1. A bag-in-a-drum container for storage and dispensing of liquid, comprising a substantially rigid overpack having an interior volume, and a 3-dimensional, closed liner of a flexible film material, mounted in said interior volume, having a zero headspace conformation and capable of being filled with liquid, the liquid comprising a reagent for semiconductor manufacturing.

Abstract
A “bag-in-a-drum” container for storage and dispensing of fluids. The container is adapted to minimize volumetric space requirements in storage, transport and use of the container. The containers are usefully employed in a system of supplying liquid in containers to an end user market and refabricating containers subsequent to consumption of the liquid from the containers.

31. The container of claim wherein the overpack includes a coupling member that is matably engageable with a coupling member of a corresponding container, whereby multiple containers may be laterally coupled with one another to constitute a laterally extending array of containers.
- 36. A bag-in-a-drum container for storage and dispensing of high-purity liquid, comprising a substantially rigid overpack having an interior volume, and a 3-dimensional, closed liner of a flexible film material, mounted in said interior volume and capable of being filled with liquid, wherein the overpack comprises a substantially rigid receptacle portion including opposedly facing front and back walls and opposedly facing side walls, and a floor member, wherein the front, back and side walls are downwardly tapered and the overpack includes an upper portion that is removable or otherwise configured to allow nested vertical stacking of at least the substantially rigid receptacle portion of the container in a vertically stacked array of corresponding containers, wherein said receptacle portion of the container has a substantially rectangular parallelepiped conformation, said liner is formed of a virgin polymeric film material having a thickness in a range of from about 0.005 inch to about 0.030 inch, and said liner has a zero headspace conformation when filled with liquid, the liner having at least one port accommodating coupling of the liner with a connector for transfer of fluid into or out of the liner, the liner filled with a liquid reagent, and a cap coupled with said port, with the receptacle portion being formed of a substantially rigid polymeric material.
