A frangible blister packaging for mixing and dispensing fluid at point of use. A multi-compartment force activated container formed by sealing a lidding closure material over formed fluid filled independent containment cavities interconnected by a pressure release frangible sealing area there between. A mixing flow path is initiated by compression on the upstream flexible compartment, forcing content fluid to mix into the downstream compartment for dispensing therefrom. The frangible sealing area is formed independently of the container compartment sealing assuring a force fluid transfer stream projection for maximum fluid inter-mixing before dispensing by compression of upstream compartment.

1. A method of making a frangible blister mixing and dispensing package which comprises, a. a base of synthetic resin material,b. forming at least two liquid retaining cavities and a dispensing spout in communication with one of said cavities within said base,c. filling said respective cavities with independent liquids to be mixed,d. positioning a thin flexible closure sheet over said cavities and dispensing spout and remaining base surface material thereabout,e. applying heat, pressure and dwell time to said overlying closure sheet and base material by respective opposing die surfaces having first and second opposing textured faces sealing said closure sheet to said base, forming a first liquid filled chamber and a second liquid filled chamber with a dispensing spout,f. applying heat, pressure and dwell time to a portion of said closure sheet and said base between said first and second liquid filled form chambers by said second opposing textured face die surfaces of reduced relief dimension, defining a frangible communication path there between,g. weakening portions of said sealed closure and base adjacent an end dispensing tip portion of said dispensing spouth. sealing said first and second textured faces opposing the surface of differing relief dimension in an aligned cross hatch sealing pattern between said closer material and said cavity forming base material. 2. The methods set forth in claim 1 wherein the forming of at least two liquid retaining chambers and a dispensing spout is by plug assist molding technique. 3. The method set forth in claim 1 wherein the applied heat, pressure and dwell time of said respective first and second opposing textured face die surfaces is digitally controlled. 4. The method set forth in claim 1 in wherein were in said first opposing textured face dies seals said closure sheet to said base around the perimeter of said respective chambers defining a passageway there between. 5. The method set forth in claim 1 wherein said cavities forming base of synthetic resin material is of a dimensional rigidity greater than that of said flexible closure sheet. 6. The method set forth in claim 1 wherein weakening portions of said sealing and closure base comprises, oppositely disposed perimeter edge transversely aligned notches therein defining a break-away tab portion. 7. The method set forth in claim 1 wherein weakening portions of said sealed closure and base adjacent an end dispensing tip portion of said dispensing spout further comprises, aligned perforations. 8. The method set forth in claim 1 wherein applied external pressure on said first liquid filled chamber ruptures said frangible communication path between said first and second liquid filled chambers forcing fluid transfer and mixing in said second fluid filled chamber with said dispensing spout.
