A standing pouch includes an external pack, and an internal pack which is disposed in the external pack to form a first temperature control space and a second temperature control space which are spaced from each other, to form a contents accommodating space between the first temperature control space and the second temperature control space to accommodate contents. The first temperature control space can communicate with the second temperature control space. A first temperature control member and a second temperature control member are respectively disposed in the first temperature control space and the second temperature control space, and at least one of the first temperature control space and the second temperature control space have an open upper side to put a reactant liquid reacting with the first and second temperature control members to generate an exothermic or endothermic reaction.
