Rotatable bottle or container capping machine for screwing threaded screw caps onto a threaded mouth portion of filled bottles or containers to close filled bottles or containers, and a method of operation thereof

A closing machine to screw caps onto containers comprising bottles, jars, or similar containers, said closing machine comprising:

• a main column and a rotor being mounted on said main column;
• a plurality of capping devices being disposed about a periphery of said rotor;
• each of said capping devices comprising:
• a container carrier, a rotatable screw shaft, and a screw head to hold a cap therein;
• said screw head being disposed at an end of said screw shaft;
• a plurality of drive motors, each being operably connected to a corresponding one of said screw shafts to rotate its screw shaft and thereby screw a cap onto a container;
• a housing being disposed above said rotor and said capping devices, and being mounted on said main column;
• said main column being rotatable about a vertical machine axis to thereby rotate said rotor and said housing about said vertical machine axis;
• said housing being configured to house therein components of said closing machine;
• and
• said housing comprising an exterior having a minimized number of surface interruptions to maximize accessibility to the exterior of said housing by a cleaning and/or disinfecting medium during a cleaning and/or disinfecting process, and thereby minimize the time of the cleaning and/or disinfecting process.
