Patent ID: 8919608

Claim:
A dispensing container for dispensing a two-component liquid comprising an outer resilient container for containing one component with a neck defining an opening and an inner container, an outer surface of the inner container being substantially sealed to an inner surface of the neck, the inner container containing a piston member, which is slidably received within the inner container, and a closure member, which closes a lower end of the inner container, the piston member and the inner container defining a reservoir for containing the other component, the neck carrying a closure cap having a liquid dispensing opening, a first non-return valve communicating with the liquid dispensing opening and with the interior of the inner container, an airflow path extending through the closure cap and the piston member, the airflow path including a second non-return valve, the first non-return valve being arranged to permit liquid to flow from the inner container to the liquid dispensing opening and the second non-return valve being arranged to permit air to flow through the airflow path into the inner container, the closure cap cooperating with the piston member and being movable relative to the neck, whereby movement of the closure cap in the downward direction moves the piston member towards the closure member, which moves the closure member, thereby opening the lower end of the inner container, characterised in that the inner container has a tubular shape, that the closure member extends over substantially the entire cross-sectional area of the inner container and that when the closure cap moves downwardly the piston member, or a member connected to the piston member, contacts the closure member and moves the closure member, thereby opening the inner container, wherein the closure cap and the piston member define a liquid space and an air space, which are sealed from one another, the first non-return valve and the liquid dispensing opening communicating with the liquid space and the air space forming part of the airflow path.
