An inspection station for checking the correct placement of a lid on a filled plastic container that is traveling on a conveyor that includes: a detector plate assembly (16) that has a flat surface (32) and an inclined surface (44); a support assembly (18); a mounting assembly (22) for attaching the detector plate assembly (16) to the support assembly (18) for holding the flat surface (32) in a predetermined parallel relationship with a top or conveying surface (30) of the conveyor (12) while simultaneously allowing vertical displacement thereof; a first sensor (54) for detecting the presence of a plastic container (20) to be checked or inspected; a second sensor (56) for sending a signal when the detector plate is within a selected range of vertical displacement. In operation the plastic container traveling horizontally on the conveyor first contacts the inclined surface thereby vertically displacing the detector plate assembly (16) sufficiently for subsequently allowing the flat surface (32) to contact a top surface of the plastic container for allowing the second sensor (56) to cooperate with a notched bar (58) to determine whether the vertical displacement is outside of the selected range.
