Package Redesign Ideas

I think that I will redesign a package from the food, household appliances, or office supplies industries. I want the product to have a freebie in it, so that the consumers will prefer this company over the alternatives. I also want the packaging to be reusable to store other things in. If I do a food item, I want  the packaging to somehow limit the consumers consumption so that they won't overeat.

Update:
I think that I want to redesign a BiC multi color pen. I love having a variety of choices for color and whenever I get one of these pens I get really excited. It could come with a pack of sticky notes or a keychain.
