Device for containing fluid substance, including a bag having at least one flexible side wall, a substantially rigid neck delimiting an opening giving access to an internal cavity of the bag, shaped to at least partially accommodate a pumping member for pumping the fluid substance, and provided with a connector for connection to an external container. The bag is made from multilayer material, and the neck is made from a material different from bag material and includes a cup-shaped element having a bottom wall with at least one opening, and a side wall on the outer surface of which the upper edge of the bag is hermetically connected. The device includes a valve element for moving from an opening position, wherein the valve element makes the bag internal cavity accessible, and a closing position, wherein the valve element inhibits access to the internal cavity.

1. A device for containing a fluid substance, comprising: a bag comprising at least one flexible side wall,a substantially rigid neck extending from said bag and delimiting an opening giving access to an internal cavity of said bag, said neck being shaped to at least partially accommodate a pumping member for pumping said fluid substance, and provided with connection means for its connection to an external container,wherein the bag is made from a multilayer material, and the neck is made from a material different from that of the bag and comprises a cup-shaped element comprising a bottom wall provided with at least one opening, and a side wall on the outer surface of which the upper edge of the bag is hermetically connected;wherein said device comprises a valve element suitable for being moved at least from an opening position, wherein said valve element allows to access said internal cavity of the bag, and a closing position, wherein said valve element inhibits the access to said internal cavity of the bag,wherein the valve element is arranged at the lower edge of the bag,wherein the valve element comprises a fixed part connected to the lower edge of the bag, delimiting a passage channel for the passage of the fluid substance and provided with a breakable internal member which closes said passage channel, anda movable part connected to said fixed part and suitable for being moved between a first operating position, wherein said movable part does not interfere with said breakable internal member, a second operating position, wherein said movable part breaks said breakable internal member and leaves said passage channel open, and a third operating position, wherein said movable part closes said passage channel. 2. A 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. 3. A 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. 4. A 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. 5. A device according to claim 1, wherein the movable part of the valve element comprises connection means, and the fixed part of the valve element comprises connection counter-means suitable for cooperating with said connection means of the movable part whenever said movable part is set to its third operating position. 6. 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 opening giving access to an internal cavity of the external container, and comprising connection counter-means for cooperating with said connection means of said neck of the bag. 7. A system according to claim 6, wherein the side wall of the bag of the device 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. 8. A system according to claim 6, wherein the cup-shaped element of the device 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. 9. A system according to claim 8, 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. 10. A system according to claim 6, wherein the movable part of the valve element of the device comprises connection means, and the fixed part of the valve element of the device comprises connection counter-means suitable for cooperating with said connection means of the movable part whenever said movable part is set to its third operating position.
