Abstract

The present invention relates to a packaging unit designed to absorb and/or adsorb liquid that is being transported or was spilled or was released. The packaging unit has at least one sealing multi-layer comprising a first water soluble film and an absorbent/adsorbent material. When the liquid contacts the water soluble film, the liquid passes through the water-soluble film. When the liquid contacts the absorbent/adsorbent material, the absorbent/adsorbent material immobilizes the liquid material. This immobilization prevents the liquid from escaping from the packaging container.

Claims

1. A container useful to transport a liquid comprising:

a spiral-wound wall having an exterior surface, at least one open end, an interior surface wherein the interior surface defines a portion of a boundary of a cavity;

a super-absorbent lining adhered to the interior surface in a sufficient amount to convert the liquid into a gel-like state when the liquid comes in contact therewith;

a closure lid impermeable to fluids and frictionally engaged with the container for closing the open end.

2. The container of claim 1 wherein the lid is frictionally engaged with the container by first threads on the wall adjacent the open end and matching second threads on the closure lid.

3. The container of claim 1 wherein the lid is frictionally engaged with the container by at least one rib nesting within a groove.

4. The container of claim 1 wherein the lid is frictionally engaged with the container by a friction fit between the wall and the closure lid.

5. The container of claim 1 wherein the super-absorbent material is polyacrylate.

6. The container of claim 1 wherein the liquid is contained within a vial.

7. The container of claim 1 wherein the spiral-wound wall is cylindrical.

8. A container useful to transport a liquid comprising:

a spiral-wound wall having an exterior surface, at least one open end, an interior surface wherein the interior surface defines a portion of a boundary of a cavity;

a super-absorbent lining adhered to the interior surface in a sufficient amount to convert the liquid into a gel-like state when the liquid comes in contact therewith;

the open end communicating with the cavity through which the liquid is introduced;

a closure lid impermeable to fluids and frictionally engaged with the container for closing the open end.

9. The container of claim 8 wherein the lid is frictionally engaged with the container by first threads on the wall adjacent the open end and matching second thread on the closure lid.

10. The container of claim 8 wherein the lid is frictionally engaged with the container by at least one rib nesting within a groove.

11. The container of claim 8 wherein the lid is frictionally engaged with the container by a friction fit between the wall and the closure lid.

12. The container of claim 8 wherein the super-absorbent material is polyacrylate.

13. The container of claim 8 wherein the liquid is contained within a vial.

14. The container of claim 8 wherein an upper edge defines the open end and the closure lid comprises:

a planar member sufficient in area to cover the open end;

a circular member extending downwardly from the planar member and having a friction fit with the wall when the planar member is in engagement with the upper edge.

15. The container of claim 8 wherein the spiral-wound wall is cylindrical.

16. A container useful to transport a liquid comprising:

a cylindrical wall having an exterior surface that is impermeable to fluids, at least one open end, an interior surface wherein the interior surface defines a portion of a boundary of a cavity;

a super-absorbent lining adhered to the interior surface in a sufficient amount to convert the liquid into a gel-like state when the liquid comes in contact therewith

a closure lid impermeable to fluids and frictionally engaged with the container for closing the open end.

17. The container of claim 16 wherein the lid is frictionally engaged with the container by first threads on the wall adjacent the open end and matching second threads on the closure lid.

18. The container of claim 16 wherein the lid is frictionally engaged with the container by at least one rib nesting within a groove.

19. The container of claim 16 wherein the lid is frictionally engaged with the container by a friction fit between the wall and the closure lid.

20. The container of claim 16 wherein the super-absorbent material is polyacrylate.

21. The container of claim 16 wherein the liquid is contained within a vial.

22. A container useful to transport a liquid comprising:

a cylindrical wall having an exterior surface that is impermeable to fluids, at least one open end, an interior surface wherein the interior surface defines a portion of a boundary of a cavity;

a super-absorbent lining adhered to the interior surface in a sufficient amount to convert the liquid into a gel-like state when the liquid comes in contact therewith;

the open end communicating with the cavity through which the liquid is introduced;

a closure lid impermeable to fluids and frictionally engaged with the container for closing the open end.

23. The container of claim 22 wherein the lid is frictionally engaged with the container by first threads on the wall adjacent the open end and matching second threads on the closure lid.

24. The container of claim 22 wherein the lid is frictionally engaged with the container by at least one rib nesting within a groove.

25. The container of claim 22 wherein the lid is frictionally engaged with the container by a friction fit between the wall and the closure lid.

26. The container of claim 22 wherein the super-absorbent material is polyacrylate.

27. The container of claim 22 wherein the liquid is contained within a vial.

28. The container of claim 22 wherein an upper edge defines the open end and the closure lid comprises:

a planar member sufficient in area to cover the open end;

a circular member extending downwardly from the planar member and having a friction fit with the interior surface to complete a seal when the planar member is in engagement with the upper edge.
