Disposable Fast food nipples and sippy cups

  My idea is to have disposable nipples that screw onto kids milk jugs at fast food restaurants. Restaurants can keep these on hand just as they do straws and lids for regular disposable cups. I also would like to see disposable sippy cup lids that latch onto the regular disposable cups. I am a mother and found this would be helpful when I forgot to bring my childs bottle or sippy cup.
