DISPENSING CONTAINER Russian patent published in 2014 - IPC B65D1/32 

FIELD: packaging industry.

SUBSTANCE: container is intended for dispensing a two-component liquid, it comprises an outer resilient container (2) for accommodating one component, having a neck (4) limiting the opening, and an inner tubular container (16). The inner container (16) comprises a piston (20, 22) located in it with the ability of sliding. The closing element (18) extends along the entire area of the inner container and closes the lower edge of the inner container (16). The piston and the inner container form a container for accommodating the second component. The neck (4) comprises a cover (10, 12) which has a dispensing opening (38) for the liquid. The first non-return valve (24, 32) communicates with a dispensing opening (38) for liquid and the inner part of the inner container (16). The channel for air passage extends through the cover (10, 12) and the piston (20, 22) and comprises a second non-return valve. The first non-return valve is made to provide the ability of the liquid movement from the inner container to the dispensing opening for liquid, and the second non-return valve is made to provide the ability of the air movement through the channel for the passage of air into the inner container. The cover (10, 12) interacts with the piston (20, 22), whereby the downward movement of the cover results in movement of the piston towards the closing element. The pin (13) connected to the piston engages the closing element (18) and moves it to open thereby the inner container and providing the ability to the component located in it to fall into the component located in the outer container.

EFFECT: improved operational characteristics.
