Internal cleaning of inverted cans includes engaging a can's cylindrical wall with a wall-conforming vacuum or adhesive gripper, causing a spraying unit to travel axially in and out of the can's opening while the can is inverted on a circular conveyor, and using a supporting arm or bottom stop to subject the can to a counterforce against a flushing force from sprayed cleaning medium. This prevents the can from being pressed out of a receptacle in which it sits during cleaning.

1. A process for internally cleaning inverted cans, each of said cans having a respective opening, said process comprising engaging a cylindrical wall of a can using a gripper that conforms to said cylindrical wall, said gripper being selected from a group consisting of a vacuum gripper and an adhesive gripper, causing an axially moving spraying unit for emission of a cleaning medium to travel in and out of said opening for internal cleaning of said can, cleaning said can by treating said can in an inverted position along a circular conveyor with said cleaning medium, wherein said spraying unit applies a flushing force to a base of said can, and subjecting said can to a counterforce to counter said flushing force, wherein subjecting said can to a counterforce comprises applying a counterforce with a supporting arm or bottom stop, thereby preventing said can from being pressed out of a receptacle in which said can is seated during cleaning. 2. The process of claim 1, further comprising guiding said can into said inverted position prior to internally cleaning said can. 3. The process of claim 1, further comprising conveying said can in the inverted position after internally cleaning said can. 4. The process of claim 2, further comprising turning said can, which is in the inverted position, into a filling position after internally cleaning said can. 5. The process of claim 1, further comprising, after internally cleaning said can, flushing said can with a gaseous pressurized sterilizing medium. 6. The process of claim 1, wherein said gripper is a vacuum gripper, said process further comprising creating a negative pressure to cause said vacuum gripper to engage said cylindrical wall. 7. The process of claim 1, wherein said gripper is an adhesive gripper, said process further comprising providing a surface of said adhesive gripper with a material that adheres to said cylindrical wall of said can with greater force than a metal would adhere to said cylindrical wall. 8. A process for internally cleaning an inverted can having an opening, said process comprising, using a clamping gripper on a wall of said can, wherein said gripper clamps said wall by applying a suction force to hold said can, causing an axially moving spraying unit to travel in and out of said opening for internal cleaning of said can, wherein said spraying unit emits a cleaning medium, and treating said can in an inverted position along a circular conveyor with said cleaning medium, wherein said cleaning medium causes a flushing force on said can, said process further comprising applying a counterforce to counter said flushing force, wherein applying said counterforce comprises applying a counterforce with a supporting arm or back stop, thereby preventing said can from being pressed out of a receptacle in which said can is seated during cleaning. 9. A process for internal cleaning an inverted can having an opening, said process comprising, using a clamping gripper on a wall of said can, wherein said gripper clamps said wall by applying an adhesive force to hold said can, causing an axially moving spraying unit to travel in and out of said opening for internal cleaning of said can, wherein said spraying unit emits a cleaning medium that exerts a flushing force on said can, and treating said can in an inverted position along a circular conveyor with said cleaning medium, said process further comprising applying a counterforce to counter said flushing force, wherein applying said counterforce comprises applying a counterforce with a supporting arm or back stop, thereby preventing said can from being pressed out of a receptacle in which said can is seated during cleaning.
