Liquid dosing dispenser and liquid container comprising said liquid dosing dispenser

A liquid dosing dispenser, comprising:

• a housing defining an internal space comprising a first opening and a second opening, wherein the housing is configured to be attached to a container, such that a first liquid flow passage is formed from the container through the first opening into the internal space;
• a dispensing unit configured to be attached to or form an integral part with the housing, such that a second liquid flow passage is formed from the internal space of the housing through the second opening to a dispensing outlet located outside the housing;
• a first valve arranged in the internal space and configured to selectively close and open the first opening;
• a closure arranged in the internal space between the first valve and the dispensing unit, the closure being configured to selectively close and open a third liquid flow passage extending from the first liquid flow passage to the second liquid flow passage, the closure comprising a second valve and a base, wherein at least one of the base and the second valve are movable in axial direction between a resting position and a compressed position;
• a compressible resilient element arranged in the internal space between the first valve and the second valve of the closure and configured to urge the at least one of the base and the second valve from the compressed position to the resting position;
• wherein the dispensing unit is configured to move the at least one of the base and the second valve from the resting position to the compressed position upon application of an external actuating force on the dispensing unit;
• and
• wherein the second valve of the closure is further configured to be movable with respect to the base, to open the third liquid flow passage when the at least one of the base and the second valve is moved by the dispensing unit from the resting position to the compressed position and/or to close the third liquid flow passage when the at least one of the base and the second valve of the closure is moved by the compressible resilient element from the compressed position to the resting position.
