Abstract
A packaging for a liquid filling with a product packaging pouch made out of a liquid-tight and elastic material and having a reaction chamber pouch made out of a liquid-tight and elastic material. The reaction chamber pouch is completely closed, and is arranged inside the product packaging pouch and partially filled with a first reactant. An inner pouch made out of a liquid-tight and elastic material is completely closed, is arranged inside the reaction chamber pouch and exhibits a predetermined breaking point that yields when its interior pressure is increased, and is filled with a second reactant. The first and second reactant induce a temperature change upon coming into contact with each other. As a result, a temperature change can be initiated by the user on the one hand, while minimizing the risk that the filling will become contaminated with chemicals on the other.
