Abstract

A disposable container comprising a side wall, top and bottom, wherein the side wall comprises a first flexible material and the bottom comprises a rigid or semi-rigid material. The side wall top and bottom are joined together to define the container with an interior compartment for keeping a fluid inside the container. The bottom comprises at least one opening that is fluid-tightly covered with an assembly comprising a second flexible material. The assembly comprises at least one port which provides access to the interior compartment of the container. The invention also relates to a mixing system comprising the disposable container.

First claim

What is claimed is:

1. A disposable container comprising:
a side wall, top and bottom, wherein the side wall comprises a first flexible material and the bottom comprises a rigid or semi-rigid material, wherein the side wall, top and bottom are joined together to define the container with an interior compartment for keeping a fluid inside the container, wherein the bottom comprises at least one opening that is fluid-tightly covered with an assembly comprising a second flexible material and wherein the assembly comprises at least one port which provides access to the interior compartment of the container, wherein the container has a vertical central axis and a horizontal axis perpendicular to the vertical axis, wherein the bottom of the container is circular and comprises a first half and a second half divided by the diameter of the circular bottom, wherein the bottom is inclined in relation to the horizontal axis such that the first half of the bottom is inclined towards a centre of the interior compartment of the container and the second half of the bottom is inclined outwards of the centre of the interior compartment of the container.

2. The disposable container according to claim 1 , wherein the rigid or semi-rigid bottom comprises a rim that extends vertically towards the interior compartment of the container.

3. The disposable container according to claim 1 , wherein the angle of inclination is from 1°-25°.

4. The disposable container according to claim 1 , wherein the bottom comprises a drainage structure in the second half of the bottom having the lowest point in relation to the vertical axis.

5. The disposable container according to claim 1 , wherein the bottom comprises at least one mixing impeller on the first half of the bottom having the highest point in respect to the vertical axis.

6. The disposable container according to a claim 1 , wherein the top comprises a rigid or semi-rigid material.

7. The disposable container according to claim 6 , wherein the top comprises at least one opening that is fluid-tightly covered with the assembly comprising a second flexible material and wherein the assembly comprises at least one port which provides access to the interior compartment of the container.

8. The disposable container according to claim 1 , wherein the first flexible material and the second flexible material are the same materials.

9. The disposable container according to claim 1 , wherein the first flexible material and/or the second flexible material is a plastic laminate.

10. The disposable container according to claim 1 , wherein the side wall, top and bottom are joined together by a heat seal and/or an adhesive seal.

11. The disposable container according to claim 1 , wherein the bottom comprises at least two openings fluid-tightly covered with the assembly.

12. The disposable container according to claim 1 , wherein the bottom is circular and has a radius, and wherein the bottom comprises an opening in the centre of the bottom, wherein the opening has a radius that is larger than one half of the radius of the bottom.
