Why have we not invented a better distribution vessel for toothpaste?

I hate the tube. It’s messy and it’s inefficient. I’ve also optimistically tried the other attempts at toothpaste dispensary – the pump and various takes on the squeezie bottle. It seems those are still messy and they never go anywhere. We always wind up back with the ol’ tube. Why can’t we find something better? What do you think would be the optimum toothpaste distribution method?
