Abstract

A self-contained generator/fumigator and delivery system is described herein that provides for sealed containment to store, isolate and protect two or more solid and/or liquid reactants in separate chambers. Upon activation, the container facilitates robust mixing of the reactants, the containment thereof and allows the release of a pre-determined amount of gaseous products, e.g., chlorine dioxide, carbon dioxide and others, into a targeted volume of water, air or other solution.

Claims

1. A container for allowing selective combination of a plurality of materials, the container comprising:

a base comprising a peripheral wall defining an interior portion and at least one divider wall extending through the interior portion, the divider wall and peripheral wall defining at least two cavities, each cavity configured to contain one of the plurality of materials, the base further comprising a base sealing rim adjacent an upper perimeter of the peripheral wall

a lid configured to rotate with respect to the base to align a keyway and a key, one of the lid or the base including the keyway and the other of the lid or the base including the key, the lid comprising a cutter and a lid sealing track; and

at least one seal extending over and being bonded to the divider wall and the base sealing rim, the seal being configured to hold the plurality of materials in the respective cavities,

wherein;

upon alignment of the key and the keyway, the lid is configured to be moved vertically toward the base and puncture the seal with the cutter so as to allow intermixing of the plurality of materials,

upon puncture of the seal, the lid sealing track is configured to abut the base sealing rim and trap an outermost portion of the seal between the base sealing rim and the lid sealing track,

engagement of the key in the keyway prevents rotation of the lid with respect to the base while the seal is being punctured,

the cutter is configured to cut the seal adjacent the outermost portion of the seal such that the seal remains bonded to the divider wall and a tail end portion of the seal is disposed between the cutter and the peripheral wall of the base, the tail end portion being disposed radially inwardly from and adjacent the outermost portion of the seal, and wherein upon puncture of the seal, the seal does not obstruct the materials from exiting the cavities,

the lid defines a plurality of perforations configured to let gasses escape therethrough, and

the lid includes a semi-permeable membrane covering the perforations, the membrane being bonded to an interior surface of the lid.

2. A container of claim 1, wherein the lid includes a skirt configured to extend around the peripheral wall of the base.

3. A container of claim 2, wherein the peripheral wall of the base includes one of a retaining ledge or a retaining clip and the lid includes another one of the retaining ledge and retaining clip, wherein the retaining clip is configured to extend over the retaining ledge so as to hold the base and lid together.

4. A container of claim 3, wherein one of the base or the lid defines at least one clip retention slot configured to receive the retaining clip therein when the cutter is advanced through the seal so as to lock the base and lid together against further movement.

5. A container of claim 1, wherein the cutter extends adjacent to the base sealing rim and is disposed internal to a respective one of the cavities when the seal is punctured.

6. A container of claim 5, wherein the cutter has an outer surface closest to the base sealing rim and a free cutting edge positioned further from the base sealing rim than the outer surface.

7. A container of claim 6, wherein the the tail end portion extends between the outer surface of the cutter and the base sealing rim.

8. A container of claim 1, wherein the base includes a guide track configured to guide the base for filling of the cavities.

9. A container of claim 8, wherein the base defines a guide track alignment key configured to align the base and its guide track.

10. A container of claim 1, wherein the lid and base include overlapping skirt and peripheral walls.

11. A container of claim 10, wherein alignment of the key and keyway allow compression of the lid and base together to increase overlap of the skirt and peripheral walls along with puncture of the seal.

12. A container of claim 11, wherein sufficient space remains between the compressed lid and base to allow intermixing of the materials in a mixing space defined by the lid and the base after puncture of the seal.
