A dispensing system includes a collapsible container for liquid material, such as soap, with an outlet for withdrawal of liquid material during collapse thereof. The dispensing system includes a support structure configured for wall attachment of the dispensing system. The support structure further includes at least one movable follower biased towards a collapsing part of the collapsible container, and a detector for reading the position of the movable follower. Detectable substance can be added to the movable follower or the collapsible container. The detector can actuate an alert indicator for indicating a low level of liquid in the collapsible container. Also a collapsible container with detectable substance is disclosed for use in such a system.

1. A dispensing system comprising a collapsible container for liquid material, wherein the collapsible container has an outlet in the bottom part for withdrawal of said liquid material from the collapsible container during collapse thereof, wherein the collapsible container comprises a pump connected to said outlet of the collapsible container such that said liquid material can be withdrawn upon activation of a dosing member associated with said pump; a support structure configured for wall attachment of said dispensing system; anda lower holder that secures said collapsible container to said support structure,wherein said support structure further comprises at least one movable follower biased towards a collapsing part of said collapsible container, and a detector that detects the position of the movable follower, andwherein the movable follower and the detector are arranged spaced apart from each other on the support structure, and the distance between the movable follower and the detector decreases as said liquid is drawn from the collapsible container. 2. The dispensing system according to claim 1, wherein the detector is capable of detecting said liquid material in the collapsible container by detecting the position of the movable follower, such that the position of the movable follower is a reflection of a remaining amount of said liquid material in the collapsible container. 3. The dispensing system according to claim 1, wherein at least a part of the collapsible container is positioned between the movable follower and the detector. 4. The dispensing system according to claim 1, wherein at least one element is arranged to support one side of the collapsible container when it is installed in the support structure. 5. The dispensing system according to claim 1, wherein the detector is arranged to detect a detectable substance in or on the movable follower, said detectable substance is chosen from the group consisting of metallic substance, magnetic substance, conductive substance, coloured substance, fluorescent substance, and radioactive substance. 6. The dispensing system according to claim 1, wherein the detector is chosen from the group consisting of inductive sensor, magnetic sensor, capacitive sensor, resistive sensor, conductive sensor, radiation sensor, and angular sensor. 7. The dispensing system according to claim 1, wherein the collapsible container has at least one rigid portion and at least one compressible portion, and said movable follower is configured to follow the deformation of said compressible portion when the collapsible container is evacuated. 8. The dispensing system according to claim 7, wherein the rigid portion of the collapsible container is supported by the element of the support structure arranged to support one side of the collapsible container. 9. The dispensing system according to claim 7, wherein the movable follower is biased towards at least a part of the compressible portion of the collapsible container such that the movable follower may influence the deformation of the collapsible container. 10. The dispensing system according to claim 1, wherein the collapsible container is supported by a top holder fastened at an upper part of the support structure. 11. The dispensing system according to claim 10, wherein the support structure is provided with at least one guiding railing for said movable follower, said guiding railing is capable of guiding the movable follower from an upper position to a lower position, in the vertical direction, such that the movable follower influences the deformation of the collapsible container by gravity. 12. The dispensing system according to claim 1, wherein the movable follower is provided in the form of a plate connected to a lever, whereby the lever is pivotally attached to the support structure around a pivot axis allowing the plate to follow the deformation of the collapsible container. 13. The dispensing system according to claim 1, wherein the movable follower is biased towards a compressible portion of said collapsible container by a spring allowing the movable follower to follow the deformation of the collapsible container. 14. The dispensing system according to claim 1, wherein the movable follower is detectable through the collapsible container when the container is substantially collapsed. 15. The dispensing system according to claim 1, wherein the movable follower is detectable by the detector from a distance of less than 15 mm. 16. The dispensing system according to claim 1, wherein the dispensing system further comprises an alert indicator that indicates the filling state of the collapsible container, wherein the alert indicator is activated in response to the detection of the movable follower by the detector. 17. The dispensing system according to claim 16, wherein the alert indicator is configured to trigger actions to alert the service personnel of the upcoming depletion of the collapsible container. 18. The dispensing system according to claim 1, wherein a detectable substance is added to the outside of a compressible portion of the collapsible container at a position where said detectable substance will be in contact with the movable follower when the movable follower presses against the collapsible container. 19. A dispensing system comprising a collapsible container for liquid material, wherein the collapsible container has an outlet in the bottom part for withdrawal of said liquid material from the collapsible container during collapse thereof, wherein the collapsible container comprises a pump connected to said outlet of the collapsible container such that said liquid material can be withdrawn upon activation of a dosing member associated with said pump; a support structure configured for wall attachment of said dispensing system; anda lower holder that secures said collapsible container to said su ort structure,wherein said support structure further comprises at least one movable follower biased towards a collapsing part of said collapsible container, and a detector that detects the position of the movable follower, andwherein the movable follower is pivotally attached to the support structure around a pivot axis allowing the movable follower to follow the deformation of the collapsible container. 20. The dispensing system according to claim 19, wherein the detector is an integral part of the movable follower. 21. A collapsible container for liquid material, comprising: an outlet in a bottom part for withdrawal of the liquid material from the collapsible container during collapse thereof;a pump connected to said outlet of the collapsible container such that the liquid material can be withdrawn upon activation of a dosing member associated with said pump;a detectable substance fastened to the outside of a compressible portion of the collapsible container where said detectable substance will be in contact with a movable follower on a support structure when the movable follower presses against the collapsible container upon securing the collapsible container to the support structure.
