Abstract

There is disclosed a system for maintaining and dispensing articles in an aseptic environment. The system includes a cabinet of modular units having at least one bank of shelves. Each bank has an open end and a closed end such that the open end is oriented toward a dispensing chute. Each bank contains a plurality of horizontally adjustable shelves laterally disposed in the bank. The shelves are divided by a plurality of dividers to define a series of slots on each shelf. A dispensing chute is located adjacent the open end of the bank and is adapted to provide gravity feed of an article. The articles are feed toward the dispensing chute by a feeding means such as an auger and the leading article is discharged by gravity. The operation of the feed means is controlled by a microprocessor or the like to control the delivery of articles to the dispensing chute. There is also disclosed a prepackaged cartridge of articles for use in the dispensing system.
