Abstract

A container for transporting and/or processing a biopharmaceutical fluid, the container comprising a wall, the wall comprising a shape memory material being adapted to change shape when induced by an external stimulus, so that the container can be alternately in a collapsed state and in an unfolded state, the wall of the container in the unfolded state delimiting an internal cavity adapted to contain the biopharmaceutical fluid.

First claim

The invention claimed is:

1. A container for processing and/or transporting a biopharmaceutical fluid, the container comprising a wall, the wall comprising a shape memory material being adapted to change shape when induced by a stimulus external to the container, so that the container can be alternately in a collapsed state and in an unfolded state, the wall of the container in the unfolded state delimiting an internal cavity of the container adapted to contain the biopharmaceutical fluid, the container being coupled to an external device to provide said stimulus to the wall of the container from a position that is external to the interior cavity of the container, wherein the container is substantially flat in the collapsed state.

2. The container according to claim 1 , wherein the internal cavity is completely surrounded by the wall so as to form a closed and sterile internal cavity.

3. The container according to claim 1 , wherein the wall comprises a top wall that is partially or completely open so as to form an opening emerging in the internal cavity.

4. The container according to claim 1 , wherein the wall comprises an inner face compatible with and/or neutral to the biopharmaceutical fluid, the biopharmaceutical fluid being directly in contact with the inner face.

5. The container according claim 1 , wherein an internal pouch made of plastic material, flexible and leak-tight, is arranged in the internal cavity, the internal pouch being suited and intended to receive the biopharmaceutical fluid, wherein the internal pouch is reversibly fixed to the inner face, the internal pouch being an element distinct and separate from the container.

6. The container according to claim 1 , wherein an internal pouch made of plastic material, flexible and leak-tight, is arranged in the internal cavity, the internal pouch being suited and intended to receive the biopharmaceutical fluid, wherein the internal pouch is irreversibly fixed to the inner face of the container.

7. The container according to claim 1 , wherein the wall comprises at least one layer of shape memory material.

8. The container according to claim 1 , wherein the shape memory material is in the form of filaments arranged in the wall of the container.

9. The container according to claim 1 , wherein the shape memory material is in a first shape when the container is in the collapsed state, the shape memory material being in a second shape when the container is in the unfolded state, the change from the first shape to the second shape of the shape memory material being induced by the external stimulus.

10. The container according to claim 1 , wherein the shape memory material is a shape memory polymer and/or a shape memory alloy.

11. The container according to claim 1 , wherein the shape memory material is a thermally or electrically induced shape memory material.

12. The container according to claim 1 , wherein the internal cavity has a capacity of between 100 litres and 1000 litres.

13. The container according to claim 1 , comprising a bottom wall linked to the lateral peripheral wall, the lateral peripheral wall being arranged vertically and transversely to the bottom wall such that the container in the unfolded state is in the form of a tank.

14. A method for facilitating receiving and transporting biopharmaceutical fluid, comprising:
providing the container of claim 1 ;
expanding the container using the external device to induce a stimulus to change shape of the memory material of the wall to arrange the container in the unfolded state from the collapsed state; and
filling the internal cavity of the container in the unfolded state with biopharmaceutical fluid.

15. The container according to claim 1 , wherein the wall comprises a sufficient rigidity to support itself in the unfolded state prior to containment of the biopharmaceutical fluid.
