Abstract
A bottle support structure and wear plate for use in a rotary capping machine used to apply caps onto the upper threaded neck of a series of plastic containers. The plastic containers have a generally cylindrical body with an outer cylindrical periphery with a diameter and a pedaloid base with spaced pads separated by radial recesses extending from a center recess. The bottle support structure supports the weight of the bottle as the bottle is being capped be prevent the body and base of the bottle from being deformed or crushed during the capping process. The wear plate is a flat ring rotated in unison with a star wheel about a machine axis. The ring has an upwardly facing flat surface and a series of container receiving nests movable in the circular path as the ring is rotated. Each of the nests has at least one elongated bar-like abutment projecting upwardly from the flat surface a given vertical distance. The one or more abutments prevent the bottle from rotating during the capping process.
