1. A connection assembly for connection to a mouth of a flexible container, the flexible container being filled with and/or emptied of a product through the mouth of the flexible container, the connection assembly comprising: an inner ring, the inner ring having an inner ring internal perimeter and an inner ring external perimeter and having an inner flange extending continuously around the inner ring external perimeter;an outer ring, the outer ring having an outer ring internal perimeter and an outer ring external perimeter and having an outer flange extending continuously around the outer ring external perimeter, and the outer ring having a recess extending therein and continuously around the outer ring internal perimeter, the recess being defined by surfaces of the outer ring;wherein the inner flange around the inner ring external perimeter is received in the recess of the outer ring and the inner flange of the inner ring and the outer flange of the outer ring form an continuous surface defined by the exposed surface of the inner flange of the inner ring and the exposed surface of the outer flange of the outer ring;the inner ring and outer ring being adapted to interengage to trap the mouth of the flexible container between the inner ring and outer ring;the connection assembly further comprising a sealing ring, the sealing ring being provided with an abutting surface, the sealing ring being provided outside of the inner ring and outer ring, the sealing ring being sized for part of said abutment surface to abut the inner flange of the inner ring with the flexible container between the sealing ring and the inner ring and for another part of said abutment surface to abut the outer flange of the outer ring with the flexible container absent from between the sealing ring and the outer ring, said abutment surface of the sealing ring being configured to correspond to the continuous surface said abutment surface abuts, said continuous surface being defined by the exposed surface of the inner flange of the inner ring and the exposed surface of the outer flange of the outer ring;wherein the flexible container is filled with and/or emptied of a product through the mouth of the flexible container with the sealing ring abutting the continuous surface being defined by the exposed surface of the inner flange of the inner ring and the exposed surface of the outer flange of the outer ring. 2. A connection assembly as claimed in claim 1, wherein the inner ring is adapted to snap fit into engagement with the outer ring. 3. A connection assembly as claimed in claim 1, further comprising a clamping ring for clamping the outer ring and sealing ring together. 4. A connection assembly as claimed in claim 3, wherein the clamping ring has at least two parts hinged for relative movement, and a clamping mechanism for clamping the at least two parts together. 5. A connection assembly as claimed in claim 1, wherein the sealing ring is provided with a guiding projection, and the inner ring has a guiding recess on its inner diameter adapted to abut the guiding projection on the sealing ring so as to accurately position said inner ring and said sealing ring. 6. A connection assembly as claimed in claim 1, further comprising an O ring positioned between the inner flange and the recess. 7. A connection assembly as claimed in claim 1, further comprising a lip on the outer flange. 8. A flexible container having a connection assembly as claimed in claim 1, wherein an opening of the container is delimited by the internal perimeter of the inner ring, and a material of the container is folded over the inner ring such that it is trapped between the recess and the inner flange. 9. A connection assembly as claimed in claim 1, wherein the inner ring and outer ring are both circular rings or both elliptical rings or both square rings or both rectangular rings or both polygonal rings. 10. A connection assembly as claimed in claim 1, wherein the inner ring is one of: a circular ring, an elliptical ring, a square ring, a rectangular ring or a polygonal ring. 11. A connection assembly as claimed in claim 1, wherein the outer ring is one of: a circular ring, an elliptical ring, a square ring, a rectangular ring or a polygonal ring. 12. A connection assembly as claimed in claim 1, wherein the sealing ring includes a sealing flange directly engaging the outer flange of the outer ring with the inner flange of the inner ring disposed in the recess such that the inner flange is sandwiched between the sealing ring and the outer ring. 13. A connection assembly for connection to a mouth of a flexible container, the connection assembly comprising: an inner ring, the inner ring having an inner ring internal perimeter and an inner ring external perimeter and having an inner flange around the inner ring external perimeter;an outer ring, the outer ring having an outer ring internal perimeter and an outer ring external perimeter and having an outer flange around the outer ring external perimeter, and the outer ring having surfaces extending therein and defining a recess around the outer ring internal perimeter, the inner flange of the inner ring having at least in part, a configuration complementary to the recess such that the inner flange is captured within the recess, wherein the inner flange of the inner ring and the outer flange of the outer ring form a continuous surface defined by the exposed surface of the inner flange of the inner ring and the exposed surface of the outer flange of the outer ring;the inner ring and outer ring being adapted to interengage to trap the mouth of the flexible container between the inner ring and outer ring at the recess; andthe connection assembly further comprising a sealing ring, the sealing ring disposed outside the inner and outer rings, the sealing ring being sized to abut the inner flange of the inner ring and the outer flange of the outer ring for sandwiching the flexible container between the inner flange and the sealing ring, wherein the flexible container is filled with and/or emptied of a product through the mouth of the flexible container with the sealing ring abutting the continuous surface being defined by the exposed surface of the inner flange of the inner ring and the exposed surface of the outer flange of the outer ring. 14. A connection assembly as claimed in claim 13, wherein the sealing ring includes a sealing flange directly engaging the outer flange of the outer ring with the inner flange of the inner ring disposed in the recess such that the inner flange is sandwiched between the sealing ring and the outer ring. 15. A connection assembly for connection to the mouth of a flexible container, the flexible container being filled with and/or emptied of a product through the mouth of the flexible container, the connection assembly comprising: an inner ring, the inner ring having an inner ring internal perimeter and an inner ring external perimeter and having an inner flange extending around the inner ring external perimeter;an outer ring, the outer ring having an outer ring internal perimeter and an outer ring external perimeter and having an outer flange extending around the outer ring external perimeter, and the outer ring having a recess extending therein and around the outer ring internal perimeter, the recess being defined by surfaces of the outer ring, wherein the inner flange around the inner ring external perimeter is received in the recess of the outer;the inner ring and outer ring being adapted to interengage to trap the mouth of the flexible container between the inner ring and outer ring;the connection assembly further comprising a sealing ring, the sealing ring being provided outside of the inner ring and outer ring, the sealing ring being sized to abut the inner flange of the inner ring with the flexible container between the sealing ring and the inner ring and to abut the outer flange of the outer ring with the flexible container absent from between the sealing ring and the outer ring, said sealing ring having an abutment portion, said abutment portion being configured to the exposed surface of the inner flange of the inner ring and the exposed surface of the outer flange of the outer ring;wherein the flexible container is filled with and/or emptied of a product through the mouth of the flexible container with the sealing ring abutting the continuous surface being defined by the exposed surface of the inner flange of the inner ring and the exposed surface of the outer flange of the outer ring.
