Thermal container

A portable thermal container for consumer products comprising at least a storing chamber of said consumer products and at least a reaction chamber of a reagent component and of a reactive component,

• wherein said storing chamber and said reaction chamber are hermetically separated,
• wherein said reagent component and said reactive component are separated from each other and able to carry out a chemical heating or cooling reaction when in contact, respectively to heat or to cool said consumer products, wherein said reagent component is operatively connected to actuating means able to arrange said reagent component in contact with said reactive component for carrying out said chemical reaction,
• and wherein said reaction chamber extends substantially entirely along the dimension of the largest dimension of said portable thermal container and said storing chamber is arranged side-by-side to said reaction chamber to maximize the thermal exchange between said reaction chamber and said storing chamber in a homogeneous way, wherein said reaction chamber comprises at least a storing portion, each comprising said reagent component and/or said reactive component,
• and at least an expansion portion, devoid of said reagent component and of said reactive component, wherein the total volume of said expansion portions is greater than the total volume of said storing portions to allow the safe expansion of the chemical reaction gases in said reaction chamber and wherein the total volume of said storing portions is less than or equal to 30% of the total volume of said reaction chamber, preferably less than or equal to 22% of the total volume of said reaction chamber.
