The invention claimed is: 1. Packaging assembly for flowable materials comprising: a casing having at least one opening, a valve assembly mounted in the opening of the casing, and a flexible liner for accommodating the flowable material, said flexible liner being housed in the casing and connected
The invention claimed is: 1. Packaging assembly for flowable materials comprising: a casing having at least one opening, a valve assembly mounted in the opening of the casing, and a flexible liner for accommodating the flowable material, said flexible liner being housed in the casing and connected to the valve assembly; wherein the valve assembly comprises a dry break extractor valve adapted to be coupled to a corresponding coupler for closed transfer dispense of the flowable material from the packaging assembly; and wherein the opening of the casing has a first section formed to receive the valve assembly and a second section formed so that the liner connected to the valve assembly can be brought in or out of the casing. 2. Packaging assembly according to claim 1, wherein the casing is reusable. 3. Packaging assembly according to claim 1, wherein the liner is disposable. 4. Packaging assembly according to claim 1, wherein the valve assembly is disposable. 5. Packaging assembly according to claim 1, wherein the liner and valve assembly are reusable. 6. Packaging assembly according to claim 1, further comprising a tamper evidence device sealing the opening of the casing, said tamper evidence device preventing, on the one hand, the replacement of the liner and, on the other hand, the filling or dispensing of material to or from the inside of the liner without visible evidence of such replacement or filling or dispensing. 7. Packaging assembly for flowable materials comprising: a casing having at least one opening, a valve assembly mounted in the opening of the casing, a flexible liner for accommodating the flowable material, said flexible liner being housed in the casing and connected to the valve assembly, and a tamper evidence device sealing the opening of the casing; wherein the valve assembly comprises a dry break extractor valve adapted to be coupled to a corresponding coupler for closed transfer dispense of the flowable material from the packaging assembly; wherein the tamper evidence device comprises a first section which seals a dispense opening of the valve assembly and a second section which seals the part of the opening of the casing which provides access to the space between the inside of the casing and the liner. 8. Packaging assembly according to claim 6, wherein the tamper evidence device is adapted to be used once only. 9. Packaging assembly according to claim 6, wherein the casing comprises a recess in which the tamper evidence device is fixed. 10. Packaging assembly according to claim 1, wherein the second section is formed by two aligned slits arranged on opposite sides of the first section of the opening. 11. Packaging assembly according to claim 1, wherein the valve assembly and a rim of the liner are sealed to one another. 12. Packaging assembly according to claim 11, wherein the valve assembly comprises at least one rib to which the rim of the liner is sealed. 13. Packaging assembly according to claim 11, wherein the rim is sealed to the valve assembly by welding. 14. Packaging assembly according to claim 1, wherein the valve assembly comprises a self-sealing valve sealing the inside of the liner from the outside of the packaging assembly. 15. Packaging assembly according to claim 14, wherein the self-sealing valve can only be opened by connecting a particular corresponding coupler to the dry break extractor valve to permit a closed transfer of the flowable material. 16. Packaging assembly according to claim 1, wherein the flowable material can be dispensed by applying a negative pressure to the corresponding coupler coupled with the dry break extractor valve. 17. Packaging assembly according to claim 1, wherein the valve assembly is connected to a dip tube that extends from the valve assembly to a point close to the bottom of the liner. 18. Packaging assembly according to claim 17, wherein the dip tube is flexible. 19. Packaging assembly for flowable materials comprising: a casing having at least one opening, a valve assembly mounted in the opening of the casing, and a flexible liner for accommodating the flowable material, said flexible liner being housed in the casing and connected to the valve assembly; wherein the valve assembly comprises a dry break extractor valve adapted to be coupled to a corresponding coupler for closed transfer dispense of the flowable material from the packaging assembly; wherein the valve assembly is connected to a dip tube that extends from the valve assembly to a point close to the bottom of the liner; and wherein the dip tube is secured within the liner by straps that extend from the tube to circumferential sections of the liner. 20. Packaging assembly according to claim 10, wherein the dry break extractor valve involves an opening for receiving the corresponding coupler and two side parts opposite one another which both taper away from said opening. 21. Packaging assembly according to claim 20, wherein the tapered side parts end where the slits of the opening of the casing begin. 22. Packaging assembly according to claim 20, wherein the tamper evidence device seals the opening of the dry break extractor valve as well as the slits of the opening of the casing. 23. Packaging assembly according to claim 1, wherein the flexible liner is adapted to expand commensurately with the inner volume and form of the casing. 24. Packaging assembly according to claim 1, wherein the casing comprises a pressure balance valve, wherein said pressure balance valve permits the entry of air to a space between the casing and the liner while prohibiting the escape of the flowable material. 25. Packaging assembly according to claim 17, wherein the dip tube incorporates a groove which is open to the inside of the liner. 26. Packaging assembly for flowable materials comprising: a casing having at least one opening therein; a valve assembly mounted in the at least one opening of the casing; and flexible liner means for containing the flowable material, the flexible liner means being housed in the casing and having a fluid tight connection to the valve assembly; the valve assembly comprising a dry break extractor valve means capable of connection to a coupler for closed discharge of the flowable material from the packaging assembly; and the opening of the casing having a first section formed to receive the valve assembly and a second section formed so that the liner connected to the valve assembly can be brought in or out of the casing.
