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.

Claims

1. A container liner comprising a 3-dimensional, closed head liner of a flexible film.

2. The container liner of claim 1, wherein said liner is adapted for use in a container system for storage and dispensing of liquid, said container system comprising a substantially rigid overpack having an interior volume.

3. The container liner of claim 1, wherein said liner is formed of a virgin polymeric film material.

4. The container liner of claim 3, wherein the virgin polymeric film material is of a thickness in a range of from about 0.005 inch to about 0.030 inch.

5. The container liner of claim 1, wherein said container liner comprises at least one port opening.

6. The container liner of claim 5, wherein the port opening is adapted to couple the liner with a connector.

7. The container liner of claim 5, further comprising a cap coupled to said port opening.

8. The container liner of claim 5, further comprising a dip tube coupled to said port opening and within said liner.

9. The container liner of claim 1, further comprising a liquid within said liner.

10. The container liner of claim 9, wherein the liquid is a high purity liquid.

11. The container liner of claim 10, wherein the liquid has a purity greater than 99.99% by weight.

12. The container liner of claim 9, wherein the liquid comprises a semiconductor manufacturing liquid reagent.

13. The container liner of claim 12, wherein the semiconductor manufacturing reagent comprises a material selected from the group consisting of acids, solvents, bases, photoresists, dopants, metalorganic reagents, silicon source compounds, and chemical mechanical planarization compositions.

14. The container liner of claim 1, wherein said liner is formed from tubular stock material.

15. The container liner of claim 14, wherein the tubular stock material comprises a blown tubular polymeric film material.

16. The container liner of claim 1, wherein said liner is free of heat seal welded seams along the sides of said liner.

17. The container liner of claim 1, being free of plastic additives.

18. The container liner of claim 1, being free of ultraviolet stabilizers, plasticizers, antioxidants, fillers, extenders, pigments and processing agents.

19. The container liner of claim 1, wherein said liner is made from a substantially pure film selected from the group consisting of virgin polyethylene film and virgin polytetrafluoroethylene (PTFE) film.

20. A container system for storage and dispensing of liquid comprising a substantially rigid overpack having an interior volume and the container liner of claim 1 within said interior volume.
