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 packaging system comprising:

a packaging container having an exterior surface and an interior surface, a first lid, and a cavity that is designed to contain a first liquid;

the exterior surface has an water impermeable material which inhibits a second liquid from penetrating into the packaging container;

an active material (a) between the cavity and the interior surface, and (b) that will contain and immobilize the first liquid;

a nullifying agent used in association with the active material to nullify a specific undesirable quality of the first liquid, and a second lid on the packaging container that has a second active material between the second lid and the cavity that will contain and immobilize the first liquid;

2. The packaging system of claim 1 further comprising a water permeable material between the active material and the cavity.

3. The packaging system of claim 2 wherein the water permeable material and the water impermeable material each have at least one peripheral edge and are joined together at the at least one peripheral edge.

4. The packaging system of claim 1 wherein the first lid which has a lid exterior surface and a lid interior surface, and the lid interior surface is separated from the cavity by the active material.

5. The packaging system of claim 4 wherein the first lid is selected from the group consisting of a snap lid, a screw lid, an indent lid, and an overlay lid.

6. The packaging system of claim 1 wherein the active material is selected from the group consisting of a single planar absorbent/adsorbent material, a multi-planar absorbent/adsorbent material, a corrugated material having absorbent/adsorbent material, and mixtures thereof.

7. The packaging system of claim 1 wherein the active material attaches to the interior surface.

8. The packaging system of claim 1 wherein the interior surface is corrugated.

9. The packaging system of claim 1 wherein the packaging container is tamper-resistant.

10. The packaging system of claim 1 wherein the nullifying agent is mixed with the active material.

11. The packaging system of claim 1 wherein the first liquid is extracted from the gelatinous state by a biological or a chemical process.

12. The packaging system of claim 11 wherein the biological or chemical process is osmosis.

13. The packaging system of claim 1 wherein the first liquid is extracted from the gelatinous state by a mechanical process.

14. The packaging system of claim 13 wherein the mechanical process is centrifugation.

15. The packaging system of claim 1 wherein the first liquid is contained within a vessel.

16. The packaging system of claim 1 wherein the packaging container is in the form of a cylinder.

17. The packaging system of claim 1 wherein the active material is a laminate.

18. A method of using a packaging container comprising the steps of

inserting a first liquid into a packaging container having an exterior surface and an interior surface, a first lid, and a cavity that is designed to contain a first liquid;

the exterior surface has an water impermeable material which inhibits a second liquid from penetrating into the packaging container;

an active material (a) between the cavity and the interior surface, and (b) that will contain and immobilize the first liquid;

applying a second lid on the packaging container to ensure the first liquid does not escape from the packaging container, and the second lid has a second active material between the second lid and the cavity that will contain and immobilize the first liquid.

19. The method of claim 18 wherein if the first liquid is formed into a gelatinous state, then further comprising extracting the first liquid from the gelatinous state as a liquid.

20. The method of claim 18 wherein the first liquid is in a vessel.

21. A packaging system comprising:

a packaging container having an exterior surface and an interior surface, a first lid, and a cavity that is designed to contain a first liquid;

the exterior surface has an water impermeable material which inhibits a second liquid from penetrating into the packaging container;

an active material (a) between the cavity and the interior surface, and (b) that will contain and immobilize the first liquid;

a second lid on the packaging container that has a second active material between the second lid and the cavity that will contain and immobilize the first liquid.
