The cleaning device has a laminate of a multitude of layers. The layers extend transverse to the longitudinal direction and the laminate includes two end layers having one end face each. One end layer is configured as a top layer with a top surface and one end layer, as a bottom layer with a bottom surface. The laminate is configured with a plurality of outwardly oriented fluid outlet ports for directing a fluid flow toward the tubular inner wall of the container. ## Claims ### Claim 1 A filling machine for filling open-mouth bags with bulk material wherein the open-mouth bag is at least temporarily received in a container and comprising: a cleaning apparatus for cleaning a tubular inner wall of the container of particles of the bulk material for cleaning the tubular inner wall after or during discharge and/or prior to or during inserting an open-mouth bag, the cleaning apparatus comprising a cleaning device that is movable in the container along a longitudinal direction; wherein the cleaning device comprises a laminate of a multitude of layers; wherein the laminate comprises a first end face and a second end face, the first end face configured as a top surface and the second end face as a bottom surface; and wherein the laminate is configured with a plurality of outwardly oriented fluid outlet ports for directing a fluid flow toward the tubular inner wall of the container. ### Claim 2 (depends on 1) The filling machine according to claim 1, wherein at least one fluid feed is connected with an end layer. ### Claim 3 (depends on 1) The filling machine according to claim 1, wherein the layers extend transverse to the longitudinal direction and wherein a plate composite comprises a first end layer with a first end face, and a second end layer with a second end face, wherein the first end layer is configured as a top layer with a top surface and the second end layer as a bottom layer with a bottom surface. ### Claim 4 (depends on 1) The filling machine according to claim 1, wherein the cleaning device is displaceable in the longitudinal direction for cleaning the tubular inner wall of the container and/or lifting out the open-mouth bag. ### Claim 5 (depends on 1) The filling machine according to claim 1, wherein fluid outlet ports are configured on a peripheral surface and/or at least on one end face of the laminate. ### Claim 6 (depends on 1) The filling machine according to claim 1, wherein the laminate comprises at least one fluid guiding layer (air baffle) in which a multitude of guiding ducts is configured which are coupled with fluid outlet ports. ### Claim 7 (depends on 6) The filling machine according to claim 6, wherein the guiding ducts are separated from one another by material bridges of the fluid guiding layer and extend outwardly from a radially inwardly region up to the outer edge of the fluid guiding layer. ### Claim 8 (depends on 7) The filling machine according to claim 7, wherein at least two guiding ducts extend from one radially farther inwardly guiding duct front end up to one fluid outlet port each. ### Claim 9 (depends on 1) The filling machine according to claim 1, wherein the laminate comprises a distance plate adjacent to the fluid guiding layer. ### Claim 10 (depends on 8) The filling machine according to claim 8, wherein a distributor trough is configured in the laminate by means of which the at least two guiding duct front ends are connected with one another. ### Claim 11 (depends on 10) The filling machine according to claim 10, wherein the distributor trough is formed by a through hole in the distance layer. ### Claim 12 (depends on 10) The filling machine according to claim 10, wherein the distributor trough is connected with the fluid feed. ### Claim 13 (depends on 1) The filling machine according to claim 1, wherein a fluid baffle includes a central through hole. ### Claim 14 (depends on 1) The filling machine according to claim 1, wherein a drive is provided for moving the laminate along a longitudinal direction of the tubular inner wall of the container. ### Claim 15 (depends on 1) The filling machine according to claim 1, wherein the laminate is configured with at least one supply feed-through. ### Claim 16 (depends on 1) The filling machine according to claim 1, wherein brushes are attached to an outside surface of the plate composite for cleaning the tubular inner wall. ### Claim 17 (depends on 1) The filling machine according to claim 1, wherein at least one plate of a plate composite is configured with at least one centering hole in which a centering pin is received. ### Claim 18 (depends on 1) The filling machine according to claim 1, wherein at least one plate of a plate composite consists at least substantially of metal. ### Claim 19 (depends on 1) The filling machine according to claim 1, wherein the cross section of a plate composite is matched to the inner cross section of the container, the cross section being configured for example round, rounded, oval, rectangular, undercut or star-shaped. ### Claim 20 (depends on 1) The filling machine according to claim 1, wherein the laminate comprises at least one plate. ### Claim 21 (depends on 20) The filling machine according to claim 20, wherein the laminate is designed as a plate composite and comprises multiple plates.
