Devices and a method for releasing gas in a container after closing and sealing to pressurize and/or prevent or counteract buckling thereof, and or provide structural rigidity and strength thereto and or release components. The method introduces a reactive agent into the container after filling and before sealing. The reactive agent is controlled to react to provide a gas and optionally components, which a) provides a positive pressure to prevent or counteract buckling and provide structural rigidity to the container and b) and or changes the state or characteristics of the headspace and or contents of the closed container. The devices include a closure, a cap and a container. The reactive agent is brought to chemical reaction by moistening, heating, catalyst and the like. The closure includes the reactive agent and is disposed in the container. The external trigger is a device that emits energy that provides heat to the reactive agent to stimulate the chemical reaction.

What is claimed is: 1. A method comprising: filling a container at least partially with a product; closing said container; disposing an insert in said container, said insert comprising a reaction chamber and at least one reactive agent; triggering said reactive agent to a chemical reaction that produces a gas in said reaction chamber as a byproduct of said chemical reaction; and releasing said gas from said reaction chamber to said container so as to pressurize said container. 2. The method of claim 1, further comprising releasing components concurrently with said gas into said container. 3. The method of claim 2, wherein said components are selected from the group consisting of: water, vitamins, minerals, flavor components, preservatives, oxygen scavengers, salts, electrolytes, sterilants, medicines, nutrients, organoleptics, colorants and any combination thereof. 4. The method of claim 1, wherein said chemical reaction is triggered by one selected from the consisting of; catalyst, moisture, heat and any combination thereof. 5. The method of claim 3, wherein said heating is provided by an induction heater. 6. The method of claim 3, wherein said heating is selected from the group consisting of: radiant heat, heated air, electromagnetic energy in the radio frequency (RF), high frequency (HF), very high frequency (VHF) and ultra high frequency (UHF) ranges, microwave, gamma, X-ray, ultraviolet, infrared, electromagnetic heat induction, ultrasonic energy, thermo sonic energy, laser energy, electric current and any combination thereof. 7. The method of claim 1, wherein said reactive agent is selected from the group consisting of: carbonates, nitrites, nitrates, ammonium compounds, acetates, ozones, peroxides and combinations thereof. 8. The method of claim 1, wherein said insert further comprises a separator that separates said reactive agent from another agent, and further comprising at least partially dissolving said separator with moisture to allow said reactive agent and said agent to contact one another in said reaction chamber. 9. The method of claim 1, wherein said insert includes a plurality of layers, at least first and second ones of said layers being sealed with a region therebetween, and wherein said reactive agent is disposed in said reaction chamber. 10. The method of claim 9, wherein one of said layers is a semi-permeable membrane that allows said gas to escape to said container. 11. The method of claim 1, wherein one of said plurality of layers is a heating element that when triggered by an external energy source heats said reactive agent. 12. The method of claim 11, wherein said heating element is one of said first and second layers. 13. The method of claim 11, wherein said heating element is an inductor that conducts electricity when subjected to an electromagnetic field. 14. The method of claim 1, wherein said container comprises a neck and a cap, wherein said cap is disposed on said neck, and wherein said insert is disposed on a surface of said cap. 15. The method of claim 14, wherein said gas enters a headspace of said container. 16. The method of claim 14, wherein said insert further comprises a pull tab that is bonded to said surface and that when pulled removes said insert from said surface. 17. The method of claim 14, wherein said product is liquid, wherein said liquid is initially hot, and wherein said container buckles as said liquid cools, and wherein said gas counteracts said buckling. 18. The method of claim 14, further comprising components that are released with said gas into said container. 19. The method of claim 18, wherein said components are disposed in said reaction chamber with said reactive agent. 20. The method of claim 18, wherein said components are selected from the group consisting of: water, vitamins, minerals, flavor components, preservatives, oxygen scavengers, salts, electrolytes, sterilants, medicines, nutrients, organoleptics, colorants and any combination thereof. 21. The method of claim 1, wherein said insert includes a plurality of layers, wherein said reaction chamber is disposed between at least first and second ones of said layers. 22. The method of claim 21, wherein said first layer includes one or more weakened areas that rupture as said gas pressurizes said reaction chamber to allow said gas to escape into said container. 23. The method of claim 21, wherein one of said plurality of layers includes a heating element that when activated by an external energy source provides heat to trigger said chemical reaction. 24. The method of claim 21, wherein said container comprises a neck and a cap, wherein said cap is disposed on said neck, wherein said insert is disposed on a surface of said cap, and wherein one of said plurality of layers is a closure seal with a pull tab that is disposed between said surface and said reaction chamber. 25. The method of claim 24, further comprising a secondary seal disposed between said surface and said closure seal. 26. The method of claim 21, wherein said plurality of layers further comprises a third layer that is a closure seal and a fourth layer that is an insulator disposed between said third layer and said second layer, and wherein said first and second layers are each an inductor.
