Abstract
This invention relates to a reaction vessel constructed of a flexible material including at least two reactant chambers containing two isolated reactants. The reactant chambers and reactants are separated by a frangible seal which opens under pressure, allowing the reactants to mix and react. The reaction produces a desired reactive effect on the environment surrounding the reaction vessel and any articles in that environment. A package in combination with a reaction vessel can be used to cause a reactive effect on an article within the package. The reactive effect can include a temperature change of the article or foaming a material to coat the article.
