FIELD: packaging industry.
SUBSTANCE: liner for container designed for multiple components comprises a container with a hole bounded by a peripheral edge which is connected in use with a sealing element. When using the container and the sealing element limit substantially a sealed cavity. This container comprises a fixed part and a movable part that is attached to the fixed part with the possibility of displacement relative to it under the influence of gas pressure inside the container. There is an outlet in the movable part, and a passageway for gas leakage in the container wall. A valve element is attached to the fixed part coupling with the outlet and essentially sealing it. Application of gas pressure to the inside of the container, which is higher than the pressure influencing on its outer part, leads to displacement of the movable part from the fixed part and, thus, to the exit of valve element from sealing contact with the outlet.
EFFECT: reliable automatic mixing of container components while it is opened.
