The ostomy appliance as claimed in claim 2 wherein a peel strength of the adhesive sealing of the first coupling component is greater than a peel strength of the second coupling component. 5. The ostomy appliance as claimed in claim 1 wherein the second coupling component is in the form of one or more coupling rings and wherein an outer diameter of the first coupling component is smaller than an inner diameter of the second coupling component. 6. The ostomy appliance as claimed in claim 1 wherein the inner bag liner is provided with a membrane allowing intestinal gas to escape but is impermeable to liquids. 7. An ostomy appliance comprising: an adhesive wafer, said adhesive wafer having a first hole for receiving a stoma, ureter, or catheter, said adhesive wafer having a first surface to be attached to the wearer's abdomen, back, or chest; a receiving bag attached to the adhesive wafer, said receiving bag having a second hole for receiving wastes exiting the stoma, ureter or catheter and a receiving bag bottom portion which defines a distal-most part of the receiving bag relative to said second hole; and a disposable inner bag liner forming a second bag inside the receiving bag and being releasably and reattachably attachable to the adhesive wafer by a coupling component, said disposable inner bag liner having a third hole for receiving wastes exiting the stoma, ureter or catheter, said coupling component being in the form of an adhesive flange projecting from the rim of the third hole and having a surface for releasable and reattachable sealing against a first surface of the adhesive wafer, and said inner bag liner having folds along folding lines such that said inner bag liner is compacted lengthwise prior to use, said folds being provided between the third hole and an inner bag liner bottom portion which defines a distal-most part of the inner bag liner relative to the third hole both when the inner bag liner is folded and when said inner bag liner is fully unfolded inside the receiving bag to reach a distal-most position relative to said third hole so that, when the inner bag liner is empty and in said compacted condition, said inner bag liner bottom portion is in a folded position adjacent said third hole such that initial wastes exiting the stoma, ureter or catheter will push against said inner bag liner bottom portion thus causing the folds to unfold so that said inner bag liner bottom portion moves away from said folded position adjacent the third hole to said distal-most position relative to said third hole as the liner is filled, a closed end of the compacted inner bag liner being provided with a cover to retain said inner bag liner in said compacted condition prior to use. 8.
