Abstract: A pusher system for dispensing articles includes a pusher track, on which the articles can be stacked for storage, displaying, and dispensing. The pusher system also includes a pusher plate assembly having a pusher plate urging the articles stored on the pusher track toward a dispensing location under the action of a driving unit, such as a coil spring. The pusher plate assembly has a retaining portion to be movably received in a longitudinal channel formed in the pusher track to retain the pusher plate assembly on the pusher track and allow the pusher track assembly to translate along the longitudinal channel formed in the pusher track. According to the various embodiments, the pusher plate assembly is configured to be in a rolling engagement with the pusher track as the pusher plate travels along the pusher track. Such rolling engagement can reduce friction between the pusher plate assembly and the pusher track, thereby facilitating travel of a pusher plate during the dispensing and reloading operations.
