Abstract

A container, which may or may not be in the form of a cylinder conforming generally to the shape of a cigar, having a wall thickness and constitution which permits water vapor to escape therethrough, but which will not permit water droplets or palpable moisture to pass therethrough and subsequently over-wet the material to be humidified, such as cigars. The container is adapted to house a quantity of highly absorbent material, such as acrylamide potassium or sodium acrylate copolymer, cross-linked. End caps may be used as desired, including end caps with apertures therein to permit an accelerated rate of humidification by allowing more water vapor to escape the interior of the container than is allowed by ordinary osmosis through the walls of the container.

Claims

1. A device for humidifying an enclosed volume, comprising:

a container having at least a portion thereof which is pervious to water vapor but not liquid; and

a quantity of a material disposed within said container which is capable of absorbing and retaining a predetermined quantity of water, said material changing between a granular consistency when dry to a semi-gelatinous consistency when said predetermined quantity of water is absorbed therein, and which is also capable of giving up said water by way of evaporation through a wall of said container.

2. The humidification device of claim 1, wherein said material capable of absorbing and retaining water is selected from the group consisting of acrylamide potassium acrylate copolymer, cross-linked.

3. The humidification device of claim 1, wherein said portion of said container pervious to water vapor but not liquid is comprised of propionate.

4. The humidification device of claim 1, wherein said container is in the form of an elongated cylinder between 1 and 10 inches in length and between 1/2 inch and 3 inches in diameter.

5. The humidification device of claim 4, wherein said container defines an open end, and further comprising a closure element adapted to be removably placed over said opening.

6. The humidification device of claim 5, wherein said closure element defines an aperture which is pervious to liquid.

7. The humidification device of claim 6, further comprising a means for partially closing said aperture.

8. The humidification device of claim 7, wherein said means for partially closing is a mesh screen material.

9. A method of humidifying an enclosed volume, comprising:

providing an enclosed volume;

providing a humidification device comprising;

a container having at least a portion thereof which is pervious to water vapor but not to liquid; and

a quantity of a material disposed within said container which is capable of absorbing and retaining a predetermined quantity of water, said material changing between a granular consistency when dry to a semi-gelatinous consistency when said predetermined quantity of water is absorbed therein, and which is also capable of giving up said water by way of evaporation through a wall of said container; and

placing said humidification device within said volume.

10. A method of humidifying an enclosed volume according to claim 9, wherein said material capable of absorbing and retaining water is selected from the group consisting of acrylamide potassium acrylate copolymer, cross-linked.

11. A method of humidifying an enclosed volume according to claim 9, wherein said portion of said container pervious to water vapor but not liquid is comprised of propionate.

12. A method of humidifying an enclosed volume according to claim 9, wherein said container is in the form of an elongated cylinder between 1 and 10 inches in length and between 1/2 inch and 3 inches in diameter.

13. A method of humidifying an enclosed volume according to claim 12, wherein said container defines an open end, and further comprising a closure element adapted to be removably placed over said opening.

14. A method of humidifying an enclosed volume according to claim 13, wherein said closure element defines an aperture which is pervious to liquid.

15. A method of humidifying an enclosed volume according to claim 14, further comprising a means for partially closing said aperture.

16. A method of humidifying an enclosed volume according to claim 15, wherein said means for partially closing is a mesh screen material.

17. A system for humidifying tobacco products, comprising:

a humidor for receiving tobacco products;

a humidification device comprising;

a container having at least a portion thereof which is pervious to water vapor but not to liquid; and

a quantity of a material disposed within said container which is capable of absorbing and retaining a predetermined quantity of water, said material changing between a granular consistency when dry to a semi-gelatinous consistency when said predetermined quantity of water is absorbed therein, and which is also capable of giving up said water by way of evaporation through a wall of said container; and

,

wherein said humidification device is at least partially disposed in said humidor.

18. A system for humidifying tobacco products, according to claim 17, wherein said material capable of absorbing and retaining water is selected from the group consisting of acrylamide potassium acrylate copolymer, cross-linked.

19. A system for humidifying tobacco products, according to claim 17, wherein said portion of said container pervious to water vapor but not liquid is comprised of propionate.

20. A system for humidifying tobacco products, according to claim 17, wherein said container is in the form of an elongated cylinder between 1 and 10 inches in length and between 1/2 inch and 3 inches in diameter.

21. A system for humidifying tobacco products, according to claim 20, wherein said container defines an open end, and further comprising a closure element adapted to be removably placed over said opening.

22. A system for humidifying tobacco products, according to claim 21, wherein said closure element defines an aperture which is pervious to liquid.

23. A system for humidifying tobacco products, according to claim 22, further comprising a means for partially closing said aperture.

24. A system for humidifying tobacco products, according to claim 23, wherein said means for partially closing is a mesh screen material.

25. An apparatus for humidifying tobacco products, comprising:

a container for housing a supply of aqueous material in semi-gelatinous form, said container having a first end and a second end;

said first end of said container defining a first opening for installing said supply of aqueous material into said container;

a means for sealing said first opening and for moving the container relative to a housing defining a humidifiable volume; and

means, within said housing, for receiving said second end of said container;

wherein said container has at least one side wall portion which is pervious to water vapor but not to water in liquid state.
