a dispensing member (7) for drawing the fluid through the opening (2) in the flexible container (1), wherein the dispensing member (7) comprises a connection piece (8) for attaching to the neck (3) of the flexible container (1);

wherein the flexible container (1) is fixed within the rigid outer (4) container by engaging the neck (3) of the flexible container (1) with the supply opening (6) of the rigid outer container (4).

2. The fluid dispenser of claim 1, wherein the rigid outer container (4) comprises two joinable parts, wherein one joinable part is movable into a position for allowing access to the installation opening (5) of the rigid outer container (4).

3. The fluid dispenser of claim 2, wherein the two joinable parts comprise a body (15) and a cover (16), wherein the body comprises the installation opening (5) and the cover comprises the supply opening (6).

4. The fluid dispenser of claim 2, wherein the two joinable parts comprise a body and a cover, wherein the body comprises the installation opening (5) and the supply opening (6).

5. The fluid dispenser of claim 3 or 4, wherein the cover (16) is detachably joined to the body (15).

6. The fluid dispenser of claim 3 or 4, wherein the cover (16) is joined to the body (15) by means of a hinge (17).

7. The fluid dispenser of any one of the preceding claims, wherein the rigid outer container (4) comprises at least one transparent or semi-transparent portion.

8. The fluid dispenser of any one of the preceding claims, wherein the supply opening (6) is detachably and directly engaged with the neck (3) of the flexible container (1); or alternatively the supply opening (6) is detachably and indirectly engaged with the neck (3) of the flexible container (1).

9. The fluid dispenser of any one of the preceding claims, wherein the connection piece (8) of the dispensing member (7) is directly attached to the neck (3) of the flexible container (1); or alternatively the connection piece (8) of the dispensing member (7) is indirectly attached to the neck (3) of the flexible container (1).

10. The fluid dispenser of claim 9, wherein the fluid dispenser further comprises an interconnection piece for interconnecting the connection piece (8) of the dispensing member (7) and the neck (3) of the flexible container (1), and optionally for interconnecting the supply opening (6) of the rigid outer container (4) and the neck (3) of the flexible container (1).

11. The fluid dispenser of any one of the preceding claims, wherein the supply opening (6) comprises a locking means for engaging the neck (3) of the flexible container (1) or the connection piece (8) of the dispensing member (7) or the interconnection piece, wherein the locking means limits at least one of horizontal, vertical and rotational movement of the neck (3) of the flexible container (1) or the connection piece (8) of the dispensing member (7) or the interconnection piece.

12. The fluid dispenser of any one of the preceding claims, wherein the neck (3) of the flexible container (1) or the connection piece (8) of the dispensing member (7) or the interconnection piece comprises at least one annular ring (10), wherein the at least one annular ring (10) detachably engages with the supply opening (6) thereby fixing the flexible container (1) or the dispensing member (7) or the interconnection piece within the rigid outer container (4).

13. The fluid dispenser of any one of the preceding claims, wherein the dispensing member (7) further comprises a pump means and a conveying tube (22), wherein the conveying tube (22) is disposed within the flexible container (1) when the connection piece (8) of the dispensing member (7) is attached to the neck (3) of the flexible container (1).

14. A fluid dispensing system comprising the fluid dispenser according to any one of the preceding claims and a fluid, wherein the fluid is contained in the flexible container (1) of the fluid dispenser and dispensed via the dispensing member (7).

15.

16. A method for assembling the fluid dispenser according to any one of claims 1 to 12, comprising the following steps:

providing a flexible container (1) comprising an opening (2) and a neck (3) disposed about the opening (2);

providing a rigid outer container (4) comprising an installation opening (5) and a supply opening (6);

providing a dispensing member (7) comprising a connection piece (8);

optionally providing an interconnection piece;

attaching, directly or indirectly with the interconnection piece, the connection piece (8) of the dispensing member (7) to the neck (3) of the flexible container (1); inserting the flexible container (1) within the rigid outer container (4) via the installation opening (5) ;

detachably engaging the supply opening (6) of the rigid outer container (4) with the neck (3) of the flexible container (1), either directly or indirectly with the connection piece of the dispensing member or the optional interconnection piece, thereby detachably fixing the flexible container (1) within the rigid outer container (4).
