Pressure container for receiving and mixing at least two separate components

Claim 1

A container for storing and dispensing components being mixed when dispensed from the container, the container comprising: a vertical main container openable at an upper end thereof and being sealed at all other sides thereof; at least two vertically extending internal containers disposed side by side in said main container and each containing a different component and being openable at an upper end and sealed at all other sides thereof; piston means which divides said main container into an upper pressure free chamber, in which said internal containers are positioned, and a lower chamber containing a pressure gas; a disk-shaped double wall cover having openings in a number equal to the number of said internal containers, said cover enclosing said upper end of said main container and including at least two neck portions disposed one below another and each being substantially disk-shaped, each neck portion having a peripheral rim defining each opening; at least two discharge valves each extending upwardly from said main container and each having a valve disk crimped to the peripheral rim of the corresponding neck portion; each internal container being formed as a flexible bag having a neck placed over the peripheral rim of the corresponding neck portion and crimped thereto; an adapter head secured to each valve and having manually operative means for simultaneously opening and closing each valve; and venting means provided on said cover and manually operated between an open and closed position so as to permit said piston to exert pressure on said internal container under action of pressure gas when said vent means is in said open position in which a connection is established between said upper chamber and atmosphere, said manually operated means of said adapter opening said venting means during the opening of each valve, whereby when said piston exert pressure in said internal containers and said valves are open the component of said internal containers are mixed in said adapter head and are dispensed from said container as a mixture.
