member. ### Claim 2 (depends on 1) The device according to claim 1, wherein the side wall of the bag comprises at least one flat element provided with at least an upper edge and a lower edge, wherein at least the upper edge and the lower edge are hermetically closed, the neck of the bag departing from said upper edge. ### Claim 3 (depends on 1) The device according to claim 1, wherein the cup-shaped element comprises a dip element which extends from its bottom wall to be arranged inside the internal cavity of the bag when the cup-shaped element is connected to said bag, said dip element in fluid communication with the valve. ### Claim 4 (depends on 3) The device according to claim 3, wherein the dip element has a length substantially equal to the distance that separates the upper edge from the lower edge of the bag, and is connected to the valve element at its lower end. ### Claim 5 (depends on 1) The device according to claim 1, wherein said movable part is suitable for being moved between the first operating position, wherein said movable part contacts the fixed part, and said fixed part does not interfere with said breakable internal member, and said moveable part with said breakable internal member closes said passage channel, the second operating position, wherein said movable part with said breakable internal member is spaced from said fixed part and leaves said passage channel open, and said fixed part does not interfere with said breakable internal member, and a third operating position, wherein said movable part contacts the fixed part and leaves said passage channel open and said breakable internal member is broken. ### Claim 6 (depends on 5) The device according to claim 5, wherein the movable part of the valve element comprises mating means, and the fixed part of the valve element comprises mating counter-means suitable for cooperating with said mating means of the movable part whenever said movable part is set to its first operating position and whenever said movable part is set to its third operating position. ### Claim 7 (depends on 5) The device according to claim 5, said breakable internal member comprising a membrane for closing an axial opening defined by the annular member at the free end of the elastic spring member. ### Claim 8 (depends on 1) The device according to claim 1, wherein the neck is cup-shaped and comprises a bottom wall, the valve element being arranged to rest on said bottom wall of the neck. ### Claim 9 (depends on 1) The device according to claim 1, wherein the valve element is suitable for being opened only when it is engaged by a rigid element, said valve element being arranged in such a way as to be engaged by the body of the pumping member when it is mounted in the neck, to enable the fluid substance to pass through. ### Claim 10 (depends on 1) A system for containing and dispensing a fluid substance, said system comprising: a device according to claim 1, a pumping member arranged in the neck of the bag of said device, said neck of the bag comprising connection means, an external container wherein said bag is inserted, said external container comprising a neck delimiting an
