DISPENSING CAPS FOR CONTAINERS WITH DRINKS Russian patent published in 2011 - IPC B65D47/20 

FIELD: transport, package.

SUBSTANCE: cover comprises first tubular section to be jointed with container neck and elongated actuator arranged, at least, partially inside said tubular section. First tubular section is jointed with said element by flexible annular jumper with one or multiple follow openings. One of said elements, namely, said jumper or first tubular section inner surface are connected with the first extending annular sealing flange. Said actuator may move axially between open position wherein flow openings are open and closed position wherein said sealing flange stays in sealed contact with one of the other element, jumper or tubular section inner surface, to stop communication between flow openings with atmosphere, that is, the container is tightly closed. Said cover additionally comprises insert and piston to confine the chamber. Note here that said insert comprises cylindrical wall and moving part driven by chamber inside pressure and provided with outlet opening. Said piston has peripheral edge in sliding contact with said cylindrical wall and opening receiving flow tube that passes through said outlet opening to form sliding seal with the edge of said opening. Aforesaid actuator may interact with piston in moving from closed to open position to allows piston displacement toward insert resulting in pressure increase to move insert from the piston unless flow tube comes from outlet opening in said insert. There also the container with aforesaid cover.

EFFECT: safe and separate storage of two fluids and mixing both directly before use.
