A dispenser/separator for contamination-free dispensing of a supply of cut-separable medical devices is disclosed which includes anti-contamination structure for enclosing the supply. The anti-contamination structure includes an exit port for allowing the supply to be pulled therethrough in a first direction to expose a device. Also disclosed is a cutter for separating such an exposed device from the supply by pulling the supply against the cutter in a second direction that is at an oblique angle relative to the first direction. In the preferred embodiment, the exit port takes the form of a resistance control aperture, and the cutter takes the form of a stationary knife blade that is positioned adjacent the aperture.

A presenting/dispensing system for chain-interconnected, cut-separable orthodontic/medical devices, organized into groups having a pre-selected number of patient-usable units, including a container constructed for housing such devices, and presenting/dispensing aperture substructure formed therein to allow for presenting such devices and dispensing a desired number of the same in an indexed manner. The system also includes check structure associated with the presenting/dispensing aperture substructure, which check structure is changeable, as a result of dispensing action, to a first condition that accommodates dispensing of such devices, and to a second condition, upon termination of such action, that resists slipping back of a chain of devices into the container.
