If you are looking for a great little container that will hold at least a bowl or two very tightly sealed while out and about, here is another idea you might try: In packages of 'Just For Men' hair coloring they give you a couple of gloves to wear in a clear plastic container a little like a ball (actually slightly oval). I'm sure you can buy these made somewhere maybe very cheap. Anyway, they snap shut tight and secure and will hold enough for up to maybe three bowls and seem well made and do not let any aroma out, and one should last for years.
