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.
Claims26
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 and capable of being filled with liquid, wherein said overpack and said liner are each vertically elongated, and said liner has a central port opening at an upper portion thereof when mounted in said interior volume.
A bag-in-a-drum container for storage and dispensing of liquid, comprising a substantially rigid overpack having an interior volume, a 3-dimensional, closed liner of a flexible film material, mounted in said interior volume and capable of being filled with liquid, wherein said liner has a central port opening at an upper portion of the liner when mounted said interior volume, a lid adapted to cooperatively mate with the overpack to enclose said interior volume, a gas feed passage communicating with such enclosed interior volume, to introduce gas to the enclosed interior volume to exert pressure against the liner during dispensing option, and said central port opening being adapted to engage with a dispensing assembly including a dispensing head and dip tube through which liquid is flowed during said dispensing operation.
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 containing liquid comprising a reagent for semiconductor manufacturing, a liquid dispensing port at an upper end portion of the liner, and a cap coupled to said port.
