Abstract: A refillable rack (10) for storing and dispensing a plurality of items, particularly dental trays (12), has one or more vertical slots (30) in a front wall (28). The defining edges of each slot (30) slidably engage vertical grooves (72) in the dental trays (12) such that a plurality of dental trays may be stacked in each slot. In a preferred embodiment, a movable member (76) at the bottom of each slot is biased to a first position wherein the width of the bottom of the slot (30) is narrower than the spacing between the grooves (72) for retaining the dental trays in the slot, and a second position wherein the width of the bottom of the slot (30) is equal to or greater than the spacing between the grooves (72) such that the lowermost dental tray (12) may be removed from the bottom of the slot, the movable member (76) preferably being movable to its second position by gripping the handle of the lowermost dental tray and moving it downward in the slot against the member for urging it to its second position.
