Reject bottle detection and ejection mechanisms

A reject bottle detection and ejection apparatus has a plurality of sensors positioned along the length of a belt conveyor that senses whether a bottle conveyed by the conveyor is positioned in an upright orientation, in an inverted orientation, in a sideways orientation, in a slanted orientation, or whether the bottle is damaged, and an air jet nozzle positioned downstream of the plurality of sensors that selectively emits a jet of air at a bottle conveyed past the air jet that has been sensed to be not in the upright orientation or to be damaged, thus removing the bottle from the conveyor.
