I'm currently thinking of interesting items that age overtime (beside food.) So far I got:

- Coupons which expire
- Pedometers which do stuff while you walk
- Lottery tickets
- Orbs, Charms, etc.. which changes as time goes by.
- Fines that get worst if you don't pay.

Each of these items actually do something as well. (Besides some expired items) Items like "Empty Box" is uninteresting and pointless.
