A liquid dosing device for a container includes a dosing chamber having a front end and a back end. An outlet passage is located at the front end. A plunger is located in the dosing chamber, divides it in a front and a back space, and is moveable between a forward position in which the plunger closes off the outlet passage, and a backward position, in which the front space has a maximal volume. An inlet passage provides fluid communication between the front space and the container. A timer passage provides fluid communication between the container and the back space. A release passage, being greater than the timer passage, provides fluid communication between the back space and the container. A valve assembly at the release passage includes a valve seat located at the back end of the dosing chamber.

A device for dispensing fluid from a fluid container, the device capable of being set to different discrete and repeatable/equal dispensing amounts, depending on the amount of fluid required to be dispensed by the user for various applications and uses. The device may also be set to an “off” or “closed” position to prevent accidental dispensing of fluid when not in use. The device is preferably configured to be affixed to the outer surface of a fluid container, which fluid container is preferably a flexible bag or pouch.

Pacifier devices with internal reservoirs and metering units are described. The metering units provide single dosages of an internal supplement material during a fixed period of time. For example, embodiments of pacifier devices can be utilized to provide supplemental nutrition paste or gel to undernourished infants with metered dosages as appropriate to the supplement.

The invention relates to a dosing system (1) for dosing a dosing material. The dosing system (1) has a housing (11), comprising a nozzle (70) and a supply channel (62) for dosing material, and a discharge element (80) movably mounted in the housing (11) and an actuator unit (10) coupled to the discharge element. The actuator unit (10) comprises an actuator (12) having a membrane (13) which can be pressurized by means of a pressure medium in order to move the discharge element (80) in a discharge direction (RA). The discharge element (80) is formed separately and, for coupling to the actuator unit (10), is pressed by means of a force acting on the discharge element (80) against a side surface (19) of the membrane (13) pointing in the direction of the discharge element (80). Furthermore, the invention relates to a method for controlling a dosing system (1).
