"Double Sided" Juice Containers

Ok, here is another brainstorm of mine for a new product. I am always forced to buy pineapple juice, orange juice, and other juices in the dairy case in a half gallon size. I usually just buy pineapple or grapefruit juice to mix a few drinks at the bar in my house. It usually sits in the fridge, expires and I toss it because I don't need a half gallon. What they should make is this:

A half gallon container with 2 juices in it, one quart each. It would look just like the current OJ container with the spout, but it would have 2 spouts, one on each side. In the middle of the container there would be a divider that separates the 2 juices. So when you go to the store you can buy a half gallon of pineapple and grapefruit, a quart of each. You could do this with cranberry, orange, pineapple, grapefruit, whatever, have the choice of 2. This would be perfect for your bar at home, so you don't get sick of the "same" juice and have to drink a half gallon, for people with kids where the kids like different juices.....it would offer variety without having to buy 2 containers....and both flavors would be readily available in ONE container. This could also work for chocolate/strawberry milk made by like NESQUICK........or other beverages. Thoughts?
