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.

18. A modular system for maintaining and dispensing articles for dental, medical or like applications in an aseptic environment, said system comprising:
-
a cabinet having a bank of shelves, said bank having an open end and a closed end; a dispensing chute adjacent the open end of said bank adapted to provide gravity feed of an article maintained in an aseptic condition, said dispensing chute further comprises a curtain extending over said open end of said bank of shelves thereby maintaining said articles in an aseptic condition; a plurality of downwardly inclined shelves laterally disposed in said bank of said cabinet, said shelves being divided by a plurality of vertical dividers wherein said vertical dividers define feed slots in the shelves for receiving a cartridge filled with articles in an aseptic condition to be maintained and dispensed in an aseptic condition; said cartridge comprising a detachable auger having an elongated helical coil with windings secured at a rear end to a circular plate including a drive shaft connected to said plate and operatively connectable to a drive unit and adapted to be angularly driven, said helical coil having sufficient spacing to receive an article between said windings, wherein said article is to be maintained in an aseptic condition, and said rear end means adapted to be angularly driven; a plurality of drive means positioned at the interior of the closed end of said bank, each drive means being mounted to a support wall located interiorly of the closed end of the bank and adjacent each of said slots in the shelves; means for feeding said articles in an aseptic condition toward said dispensing chute and discharging the leading article to drop by gravity, said means for feeding further comprises a removable auger feed contained within a protective sleeve; and means for controlling the delivery of articles in an aseptic condition to the dispensing chute, said control means is a keypad having a plurality of keys such that one key is associated with one slot in one of the shelves in one of the banks of shelves, said keypad located on the outer surface of said cabinet;
said keypad further comprising a clear replaceable film or sheet adapted to cover said keypad, thereby maintaining an aseptic condition.
