Abstract (en)
A self cooling packaging comprises a cavity forming a heat exchanger (20) and containing a refrigerant liquid and the vapour thereof and a cavity forming an adsorption chamber (30) for pumping of said vapour. The packaging also includes connection means (40) provided in a common wall (25) of said cavities (20, 30), said connection means comprising a check valve (42), and actuating means (45) disposed on the side of the adsorption chamber cavity (30) and adapted to open the check valve (42) to an initial position inside the heat exchanger cavity (20). The packaging further comprise spring means (43), the check valve (42) being adapted to progressively reach a fully open position under the action of said spring means (43). <??>The invention makes it possible to realise a progressive opening of the check valve inside the heat exchanger cavity. <IMAGE>
