(11) A container 1 having a flexible wall 2 has a mixer 3 and is located, at least for a mixing process, in a support container 4. The container 1 has a container interior 5 in which the mixer 3 is arranged. A mixing element 7 is arranged at one end of a mixer shaft 6. The mixing element 7 can be part of a rotary mixer, a reciprocating mixer, a magnetic stirrer or a vibratory mixer. The medium 8 to be mixed is also poured into the interior 5. Connections for media to be supplied or to be discharged are not shown. The drive 9 for the mixer 3 is arranged outside the container 1.

(12) The container 1 is inserted into the support container 4 at least for the mixing process. In this case, the lateral container wall 10 of the container 1 rests against an inner support surface 11 of a lateral support container wall 12. The container base 13 of the container 1 rests in this case on the support container base 14 of the support container 4. In the exemplary embodiment, four web-like chicanes 15 are arranged on the inner support surface 11. The chicanes 15 are fastened to the inner support surface 11 of the lateral support container wall using permanent magnets 16. In accordance with FIGS. 2 and 3, the chicanes 15 are in the form of elongate webs which are oriented in the vertical direction, i.e. parallel to the longitudinal axis 17 of the support container. The cross section 18 of the chicanes 15 is convex, i.e. rounded, in its formation relative to the longitudinal axis 17 of the support container. The chicanes 15 have a run-on surface 20 in the upper region 19 in the vertical direction. In the lower region 21 in the vertical direction, the chicanes 15 have a run-out surface 22. The chicanes 15 are coated with plastics material.

(13) In accordance with the exemplary embodiment from FIG. 8, the chicanes 15 can have a cross section 18 which is rounded convexly toward the longitudinal axis 17 of the support container and concavely laterally toward the inner support surface 11.

(14) In accordance with the exemplary embodiment from FIG. 9, the chicanes 15 are formed so as to be longer in the vertical direction than in the exemplary embodiment according to FIG. 1, and the run-on surfaces 20 and run-out surfaces 22 are flatter in their formation.

(15) According to the exemplary embodiment from FIG. 4, the chicanes 15 are formed integrally with the lateral container wall 12.
