A container, such as a bottle or jar, that includes a closed compartment and an active insert device for pressurizing the closed compartment. The active insert device comprises an elastic liner and an active insert that are affixed to a closure or cap or the container. The active insert includes at least one reactant that is triggered to a reaction by an external energy source. The reaction produces a gas, which is delivered to the closed compartment via the liner. The gas causes the liner to expand and open a passage to deliver the gas to the closed compartment.

1. A container assembly comprising: a bottle comprising:an interior;a neck finish;an upper rim defining an opening at a distal end of said neck finish; anda closure comprising:a closed top;a skirt fastened to said neck finish for closing said opening of said bottle;an active insert secured to an interior surface of said closed top, and housing at least one reactant;a liner bonded to said interior surface of said closed top to form a hermetic seal between said interior surface of said closed top and said rim of said bottle and to form an expansion chamber surrounding said active insert, said expansion chamber comprising: an elastic portion that expands from an unstretched condition to a stretched condition as pressure within said expansion chamber increases and then contracts from said stretched condition to said unstretched condition when pressure within said expansion chamber equilibrates with pressure of said interior of said bottle;a valve within said elastic portion that opens to release gas into said interior of said bottle as said pressure within said expansion chamber increases and then closes as said elastic portion contracts to said unstretched condition;wherein said at least one reactant is triggerable to a reaction by an external energy source to produce gas in said expansion chamber to increase pressure of said expansion chamber and to expand said elastic portion of said expansion chamber to open said valve through which said gas is released to said interior of said bottle. 2. The container assembly of claim 1, wherein said active insert is spaced from said liner. 3. The container assembly of claim 1, wherein said reaction is a type selected from the group consisting of: chemical decomposition, combustion, substitution, acid-base, Redox or organic reaction. 4. The container assembly of claim 1, wherein said external energy source produces the triggering of said reaction with energy selected from the group consisting of: thermal induction; photo initiation; thermally through external heating, friction generated through either mechanical or ultrasonic energy, infrared light spectrum or electric heating coil; shock, impact or vibration through the application of mechanical force, ultrasonic energy, microwave radiation; electrically through an electrostatic discharge; and directed radiation of energetic particles and electromagnetic energy. 5. The container assembly of claim 1, wherein said liner further comprises a planar surface or a recess. 6. The container assembly of claim 1, wherein said liner comprises a recess housing said active insert. 7. The container assembly of claim 1, wherein said external energy source provides electromagnetic energy, wherein said active insert comprises an inductor that responds to said electromagnetic energy to trigger said reaction. 8. The container assembly of claim 1, wherein said active insert device is disposed in a recess of said closure. 9. The container assembly of claim 1, wherein said active insert further comprises a first layer bonded to a second layer, and wherein said at least one reactant is disposed between said first and second layers. 10. The container assembly of claim 1, wherein said active insert further comprises a layer bonded to said reactant. 11. The container assembly of claim 1, wherein said neck finish is threaded and said skirt is threaded. 12. The container assembly of claim 1, wherein said reactant is a blend of any one or more selected from the group consisting of: gas generating propellants, oxidizers, stabilizers, binders, organic compounds and inorganic compounds. 13. The container assembly of claim 12, wherein said organic and inorganic compounds are selected from the group consisting of: azo and nitro compounds, amines, tetrazoles, ammonium and metal salts. 14. The container assembly of claim 1, wherein said external energy source provides light energy, wherein said active insert responds to said light energy to trigger said reaction. 15. The container assembly of claim 14, said closure further comprising a transparent section, and wherein said light energy is incident to said transparent section.
