We had a meeting last night, a decided we may have put the cart before the horse. Once we decided to go with the cartridge design, we just assumed it would have an internal "tube" holding the pills. We failed to look at alternative methods of packing/storing pills. Below are a few more pill dispenser ideas:
The idea I'm most excited about is using a blister pack because it is already an acceptable packing mechanism in the industry. We could possible also handle the reel like an SMT reel. Some potential down sides include foil chunks being dispensed, large volume required to store reel, and used strip storage. Another idea we had was using thinner plastic to hold the pills, similar to string cheese (singles) packaging.
