I'm not certain why, but the front of the waterproof liner can be pulled back from the shell (perhaps for ease of cleaning), creating a place I could carry papers as shown. This would really keep the fruit juice from the forms.

However, I just thought of a simple solution to the lunch leak problem. We use light weight waterproof dry bags all the time when we go bicycle touring. Granite Gear is high quality at a good price and they've always kept our stuff dry. I guess that can work in reverse and will also really make your lunch easy to spot in the fridge at work. I might try one of their Air Space containers for my commuter food.
