DISPENSING CONTAINER

摘要

A container for dispensing a two-component liquid comprises an outer resilient container for containing one component with a neck defining an opening and an inner tubular container. The inner container contains a piston slidably received within it. A closure member extends over the entire area of the inner container and closes its lower end. The piston and the inner container define a reservoir for containing a second component. The neck carries a closure cap which affords a liquid dispensing opening. A first non-return valve communicates with the liquid dispensing opening and with the interior of the inner container. An airflow path extends through the closure cap and the piston and includes a second non-return valve. The first non-return valve is arranged to permit liquid to flow from the inner container to the liquid dispensing opening and the second non-return valve is arranged to permit air to flow through the airflow path into the inner container. The closure cap cooperates with the piston so that movement of the closure cap in the downward direction results in movement of the piston towards the closure member. A finger connected to the piston contacts the closure member and moves it and thus opens the inner container, thereby permitting the component within it to fall down into the component within the outer container.
