How about those small single use tins that you sometimes see at the convience stores for aspirin. They are about the size of a postage stamp and hold 4 pills. You squeeze one corner and the other sides pop up.<br><br>These might have been overcome by the current single use type packets that are paper type packaging you tear open and throw away. <br><br>An alternate might be those tubes about the size of a chapstick tube that Tylenol comes in. Reuseable and hold about a dozen or so.
