A flexible container incorporating flexible front and rear sheets and one or more container ports disposed in between the sheets are discussed. The one or more container ports each has a pliable attachment flange and an integrally molded nozzle. The pliable attachment flange has a first configuration whereby the attachment flange collapses to enable heat sealing the attachment flange to the sheets and thereafter substantially recovers its shape to provide a fluid pathway with the port. Various terminal ports, terminal caps, and rubber septums may be useable with the one or more container ports.

What is claimed is: 1. A flexible container comprising: a flexible front sheet and a flexible rear sheet attached to one another along at least a portion of a common perimeter to define an interior cavity; a container port comprising a nozzle attached to a flexible attachment flange, which is attached to the flexible front and rear sheets; wherein the flexible flange comprises a first flange layer comprising an interior surface and an exterior surface attached to a second flange layer comprising an interior surface and an exterior surface; the two flange layers defining an interior cavity comprising a first opening near the nozzle and a larger second opening near the flexible front and rear sheets; and wherein the attachment flange is pliable such that at least a portion of the interior surface of the first flange layer contacts at least a portion of the interior surface of the second flange layer when the flexible attachment flange is compressed between the flexible front sheet and flexible rear sheet. 2. The flexible container of claim 1, wherein the first and second flange layers are connected together along two common edges. 3. The flexible container of claim 2, wherein the two common edges are creases formed from integrally molding the first and second flange layers. 4. The flexible container of claim 2, wherein the two common edges each comprises a fin. 5. The flexible container of claim 4, wherein the fins extend outwardly from the two common edges. 6. The flexible container of claim 5, wherein the fins each tapers as it extends outwardly away from the common edge that it extends from. 7. The flexible container of claim 1, wherein the flexible front and rear sheets each comprises a multi-layer film. 8. The flexible container of claim 7, wherein the multi-layer film comprises three distinct film layers. 9. The flexible container of claim 7, wherein a layer of the multi-layer film is made from a blend of polypropylene-ethylene random copolymer and styrene ethylene-butylene styrene (SEBS) thermoplastic elastomer. 10. The flexible container of claim 9, wherein a second layer of the multi-layer film is made from either a polyether block amide copolymer (PEBA) or an abuse resistant material containing ester groups (EGM). 11. The flexible container of claim 10, wherein a third layer of the multi-layer film is made from SEBS if the second layer is made from EGM, and wherein the third layer is made from carboxy modified polypropylenes if the second layer made from PEBA. 12. The flexible container of claim 1, wherein the container port is made from a blend of polypropylene-ethylene random copolymer and styrene ethylene-butylene styrene thermoplastic elastomer. 13. The flexible container of claim 12, wherein the blend is in a weight-weight ratio of about 90:10 to about 70:30 of polypropylene-ethylene random copolymer to styrene ethyl ene-butylene styrene. 14. The flexible container of claim 1, further comprising a powder medicament, a liquid medicament, or both in the interior cavity. 15. A method for forming a flexible container comprising: joining a flexible front sheet to a flexible rear sheet along at least a portion of a common perimeter to define an interior cavity; placing a flexible attachment flange in between the flexible front sheet and flexible rear sheet, said attachment flange having a container port comprising a nozzle attached thereto; wherein the flexible attachment flange comprises a first flange layer, which has an exterior surface and an interior surface, attached to a second flange layer, which has an exterior surface and an interior surface; applying a heat bar over at least one of the flexible front sheet and the flexible rear sheet to compress the attachment so that the interior surface of the first flange layer collapses towards the interior surface of the second flange layer to seal the attachment flange to the flexible front and rear sheets. 16. The method of claim 15, further comprising attaching a second attachment flange, which has a port attached thereto, to the flexible front and rear sheets. 17. The method of claim 15, wherein the attachment flange has two tapered edges. 18. The method of claim 15, further comprising adding a powder medicament, a liquid medicament or both to the interior cavity. 19. The method of claim 15, further comprising joining the flexible front sheet with the flexible rear sheet by a peelable seal to create a compartment. 20. The method of claim 15, wherein the nozzle is attached to a terminal port. 21. The method of claim 20, further comprising a peelable foil layer attached to the terminal port. 22. The method of claim 21, wherein the flexible front sheet or the rear sheet or both comprise a multi-layer film. 23. A method for forming a flexible container comprising: joining a flexible front sheet to a flexible rear sheet along at least a portion of a common perimeter to define a cavity; placing a flexible attachment flange in between the flexible front sheet and the flexible rear sheet in a weld area for attaching the attachment flange to the flexible front and rear sheets, the flexible attachment flange comprising a first flange layer and a second flange layer and a container port; applying at least one heat bar to the weld area to attach the attachment flange to the flexible front and rear sheets, said heat bar causing the first flange layer to collapse towards the second flange layer during the applying step. 24. The method of claim 23, wherein the flexible front sheet or the flexible rear sheet or both comprise a multi-layer film. 25. The method of claim 24, wherein the multi-layer film comprises three distinct film layers. 26. The method of claim 25, wherein a layer of the multi-layer film is made from a blend of polypropylene-ethylene random copolymer and styrene ethylene-butylene styrene (SEBS) thermoplastic elastomer. 27. The method of claim 26, wherein a second layer of the multi-layer film is made from either a polyether block amide copolymer (PEBA) or an abuse resistant material containing ester groups (EGM). 28. The method of claim 27, wherein a third layer of the multi-layer film is made from SEBS if the second layer is made from EGM, and wherein the third layer is made from carboxy modified polypropylenes if the second layer made from PEBA. 29. The method of claim 23, wherein the container port is made from a blend of polypropylene-ethylene random copolymer and styrene ethylene-butylene styrene thermoplastic elastomer. 30. The method of claim 29, wherein the blend is in a weight-weight ratio of about 90:10 to about 70:30 of polypropylene-ethylene random copolymer to styrene ethylene-butylene styrene. 31. The method of claim 23, further comprising a powder medicament, a liquid medicament, or both in the interior cavity. 32. The method of claim 31, wherein the cavity is divided into a first compartment by a peelable seal for containing the liquid medicament and a second compartment for containing the powder medicament. 33. The method of claim 23, wherein the flexible front sheet and the flexible rear sheet are connected to one another along a singularly formed fold line.
