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.

A wall-mounted metering dispenser for a liquid, having a replaceable container and a wall bracket, and having a removal apparatus for removing liquid from the container in a metered manner. The wall bracket has a first fixing location having a fixed retention element for the base region of the container, and a second fixing location having a sleeve which can is separable from or movable relative to the wall bracket which retains the upper region of the container. The removal apparatus is arranged on or integrated in the sleeve and includes a metering pump having a pump chamber that is insertable in the container opening and a pump valve and an actuation element that is movable relative to the container and cooperates with the pump valve and has a liquid discharge opening connected to the pump chamber via a discharge channel. The actuation element is guided in the sleeve.

A dispenser for dispensing a metered dose of foam or liquid from a reservoir includes means for applying gas pressure either directly or indirectly to a liquid contained in the reservoir for dispensing a liquid or foam through a nozzle. Instead of using a direct pump, the dispenser uses gas pressure inside the dispenser that pushes the liquid out of the reservoir without coming into contact with the reservoir. The dispenser can include a battery operated gas pressure pump and a sensor that senses pressure within the dispenser. In one aspect, an actuator can open a valve for dispensing metered doses of a liquid or foam.
