A two shot dispensing closure wherein the spout and base component of the closure is molded in a first molding step and a repositionable cap is molded over at least the spout of the closure in a second molding step. The cap may be molded in the closed position over the spout to provide a fluidic seal between the cap and spout. The cap is repositionable between a closed position closing off an aperture of the spout and an open position thereby opening the aperture of the spout.

1. A two shot dispenser comprising: a dispenser including an undershot of a first material and an overshot of a second material, said first material is different from said second material, said undershot includes a flip-top base and said overshot includes a flip-top cap overmolded onto said flip-top
1. A two shot dispenser comprising: a dispenser including an undershot of a first material and an overshot of a second material, said first material is different from said second material, said undershot includes a flip-top base and said overshot includes a flip-top cap overmolded onto said flip-top base in a closed position, said flip-top base having at least one thread;said flip-top base of said undershot having a top wall with an aperture through said top wall, said top wall including an inner wall and an outer wall depending from said top wall, said outer wall and said inner wall being concentrically aligned;said flip-top cap of said overshot includes a hinge positioned between an upper portion and a lower portion of said flip-top cap, wherein said hinge of said overshot pivots said upper portion between said closed position and an open position relative to said lower portion of said flip-top cap and said flip-top base; andsaid flip-top cap upper portion of said overshot creating a seal between said overshot and said undershot, wherein said seal engages said aperture of said flip-top base top wall. 2. The two shot dispenser as in claim 1 wherein said seal releasably engages said aperture. 3. The two shot dispenser as in claim 1 wherein said lower portion of said flip-top cap secures said upper portion and said hinge to said flip-top base. 4. The two shot dispenser as in claim 1 wherein said hinge includes a center hinge, a left hinge arm, and a right hinge arm, wherein said center hinge is located between said left hinge arm and said right hinge arm, a first opening separates said left hinge arm from said center hinge and a second opening separates said right hinge arm from said center hinge. 5. The two shot dispenser as in claim 4, wherein said first opening and said right opening are substantially crescent shaped. 6. The two shot dispenser as in claim 5, wherein said first opening includes an upper arch and a lower arch, said upper arch of said first opening extends to a point above said left hinge arm, said lower arch of said first opening extends to a point below said left hinge arm, wherein said second opening includes an upper arch and a lower arch, said upper arch of said second opening extends to a point above said right hinge arm, said lower arch of said second opening extends to a point below said right hinge arm. 7. The two shot dispenser as in claim 5, wherein each said first opening and said second opening have a taper. 8. The two shot dispenser as in claim 1, wherein said hinge includes an opening, said opening divides a pair of hinge arms. 9. The two shot dispenser as in claim 8, wherein each said pair of hinge arms include a taper on an opposing edge opposite of said opening. 10. The two shot dispenser as in claim 8, wherein said opening is substantially oval in shape. 11. The two shot dispenser as in claim 8, wherein said opening is tapered from an exterior surface of said overshot. 12. A two shot dispensing closure affixed to a container and having a flip top hinged lid, comprising: a undershot base of a first material having a skirt and at least one thread on an inner side wall of said skirt and an upwardly extending dispensing surface, said dispensing surface having an aperture for dispensing product from said container through said aperture;said undershot base including a sealing member on an inner surface of said base in contact with a container preventing said product of said container from leaking around said base skirt;an overshot flip top hinged lid of a second material overmolded in a closed position onto said undershot base, wherein said first material has a higher melting temperature than said second material;said overshot flip top hinged lid having an attachment ring surrounding said dispensing surface and a lid hingedly attached by a hinge to said attachment ring, said lid having a fluidic seal contacting said aperture of said base dispensing surface to properly seal said aperture when overmolded in said closed position onto said undershot base;wherein said hinge is a dual position hinge biasing said lid into said closed position and an open position. 13. The closure of claim 12 wherein said hinge has a first hinge strap and a second hinge strap. 14. The closure of 13 wherein said hinge includes a first and a second crescent shaped cutout forming said first hinge strap and said second hinge strap. 15. The closure of 14 wherein said first and said second crescent shaped cutout positions said lid substantially outward and away from said dispensing surface to allow a user to drink from said closure without contacting said hinged lid. 16. The closure of claim 12 wherein said hinged lid has a top surface which is parallel to a top surface of said closure base in which said aperture is located when said lid is in said closed position, said hinged lid top surface being more than 90 degrees relative to said top surface of said closure when said lid is in said open position. 17. A flip top closure having a separate second shot hinged lid, comprising: a first shot closure base of a first material having an upwardly extending frustoconical dispensing surface with a dispensing orifice on a top wall;a second shot hinged flip top lid of a second material overmolded onto said first shot closure base in a closed position, wherein said first material is different from said second material, said second shot hinged flip top lid includes a retention ring, hinge, and lid, said retention ring surrounds at least a portion of said closure at a base of said upwardly extending frustoconical dispensing surface and hinged to said lid, said hinge is overmolded directly against an exterior surface of said upwardly extending frustoconical dispensing surface and biases said lid between said closed position and an open position, said lid having a seal contacting said dispensing orifice of said first shot closure base top wall when said lid is in said closed position; andwherein said hinge biases said lid substantially away from said dispensing orifice when said lid is in said open position to prevent substantial interference of a user drinking from said dispensing orifice. 18. The closure of claim 17 wherein said hinge is formed of a first hinge strap and a second hinge strap, a first cutout forming said first hinge strap and a second cutout forming said second hinge strap. 19. The closure of claim 18 wherein said first cutout and said second cutout are mirrored crescent shaped cutouts. 20. The closure of claim 17 wherein said first shot closure base includes at least one circumferential groove receiving an overmolded portion of said retaining ring of said second shot hinged flip top lid to mount said hinged flip top lid to said first shot closure base.
