Abstract

The presently disclosed subject matter provides a package and methods for disinfecting a wide variety of microbiologically contaminated products. Particularly, the disclosed package comprises a package to house the product to be disinfected and a disinfecting gas generator positioned within the interior of the package. The materials used to construct the package and/or the gas generator comprises an active agent that neutralizes the disinfecting gas from the interior of the package. The reactivity of the active agent is balanced such that the rate of neutralizing is lower than the rate of disinfecting gas release. As a result, the disinfecting gas has time to function fully before it is neutralized. Thus, when a user opens the package at the end of the disinfecting period, exposure to the disinfecting gas is minimized or eliminated.

Claims

1. A container for disinfecting a product, said container comprising:

a. a package having an interior and a sealable opening through which said product can be placed into the interior of the package;

b. a disinfecting gas generator disposed within the interior of said package;

wherein said package comprises a pair of opposing films joined together along a pair of opposing sides and a bottom bridging the sides; and

wherein said package comprises at least one of the following;

(1) at least one of said package films comprises a neutralizing layer and an active agent carried by the neutralizing layer, (2) an active agent housed in said disinfecting gas generator, or (3) both (1) and (2).

2. The container of claim 1, wherein said disinfecting gas is selected from the group comprising:

chlorine dioxide, ethylene oxide, sulfur dioxide, nitrogen dioxide, nitric oxide, nitrous oxide, carbon dioxide, hydrogen sulfide, hydrocyanic acid, dichlorine monoxide, ozone, and combinations thereof.

3. The container of claim 1, wherein said generator is a sachet housing two reactants separated by a frangible seal, such that when the frangible seal is ruptured and the reactants are combined, disinfecting gas is generated.

4. The container of claim 3, wherein said sachet further comprises a compartment housing an active agent.

5. The container of claim 1, wherein said generator is a sachet housing two reactants and an active agent, and wherein at least one reactant is housed in a package comprising a frangible seal.

6. The container of claim 1, wherein said generator is housed in a receptacle comprising at least one fan.

7. The container of claim 1, further comprising a product disposed within the interior of the package.

8. The container of claim 1, further comprising an indicator disposed within the interior of the package, said indicator adapted to indicate when an effective amount of disinfecting gas has been generated.

9. The container of claim 1, wherein said pouch comprises a locking mechanism.

10. A method of disinfecting a product, said method comprising:

a. supplying a product to be disinfected;

b. supplying a package having an interior and a sealable opening through which said product can be placed into the interior of the package;

c. supplying a disinfecting gas generator;

d. placing said product and said generator within the interior of said package;

e. sealing said package;

f. activating said generator to introduce an amount of disinfecting gas into said interior effective to disinfect said product;

g. maintaining said package in a sealed condition for a disinfecting period;

h. opening said package and removing said disinfected product;

wherein said package comprises a pair of opposing films joined together along a pair of opposing sides and a bottom bridging the sides; and

wherein said package comprises at least one of the following;

(1) at least one of said package films comprises a neutralizing layer and an active agent carried by the neutralizing layer, (2) an active agent housed in said disinfecting gas generator, or (3) both (1) and (2).

11. The method of claim 10, wherein the concentration of disinfecting gas is sufficient to disinfect said product.

12. The method of claim 10, wherein said disinfecting period is about 8 hours or less.

13. The method of claim 10, wherein said disinfecting period is about 6 to 24 hours.

14. The method of claim 10, wherein said concentration of disinfecting gas within the interior of said package at the end of said disinfecting period is less than about 10.0, 1.0, 0.1, or 0.01 parts per million.

15. The method of claim 10, wherein said disinfecting gas is selected from the group comprising:

chlorine dioxide, ethylene oxide, sulfur dioxide, nitrogen dioxide, nitric oxide, nitrous oxide, carbon dioxide, hydrogen sulfide, hydrocyanic acid, dichlorine monoxide, ozone, and combinations thereof.

16. The method of claim 10, wherein said generator is a sachet housing two reactants separated by a frangible seal, such that when the frangible seal is ruptured and the reactants are combined, disinfecting gas is generated.

17. The method of claim 10, wherein said sachet further comprises a compartment housing an active agent.

18. The method of claim 10, wherein said generator is a sachet housing two reactants and an active agent, and wherein at least one reactant is housed in a package comprising a frangible seal.

19. The method of claim 10, wherein said generator is housed in a receptacle comprising at least one fan.

20. The method of claim 10, further comprising a product disposed within the interior of the package.

21. The method of claim 10, further comprising an indicator disposed within the interior of the package, said indicator adapted to indicate when an effective amount of disinfecting gas has been generated.

22. The method of claim 10, wherein said pouch comprises a locking mechanism.

23. A kit comprising:

a. a package having an interior and a sealable opening;

b. a disinfecting gas generator;

wherein said package comprises a pair of opposing films joined together along a pair of opposing sides and a bottom bridging the sides; and

wherein said package comprises at least one of the following;

(1) at least one of said package films comprises a neutralizing layer and an active agent carried by the neutralizing layer, (2) said disinfecting gas generator comprises an active agent, or (3) both (1) and (2).

24. The kit of claim 23, wherein said disinfecting gas is selected from the group comprising:

chlorine dioxide, ethylene oxide, sulfur dioxide, nitrogen dioxide, nitric oxide, nitrous oxide, carbon dioxide, hydrogen sulfide, hydrocyanic acid, dichlorine monoxide, ozone, and combinations thereof.

25. The kit of claim 23, wherein said generator is a sachet housing two reactants separated by a frangible seal, such that when the frangible seal is ruptured and the reactants are combined, disinfecting gas is generated.

26. The kit of claim 23, wherein said neutralizing layer is positioned directly adjacent to a permeable layer.

27. The kit of claim 23, further comprising an indicator disposed within the interior of the package, said indicator adapted to indicate when an effective amount of disinfecting gas has been generated.
