Method for pressurizing containers

摘要

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.

主权项

1. A method of pressurizing a container comprising:
disposing an expansion chamber in said container, wherein said expansion chamber has at least a portion that comprises elasticity; and initiating a reaction in said expansion chamber to produce gas that expands said portion of said expansion chamber from an unstretched condition to open a passage through which said gas is released to said container; wherein said reaction is a type selected from the group consisting of: chemical decomposition, combustion, substitution, acid-base, Redox or organic reaction.
