+ a bunch. My wife swears by those. She drags 3-4 days worth of food with her at a time and that is her container of choice for soups, salsa, cut up fruit, whatever. Claims she has never had one leak. For soup I use a SS thermos bottle of some type. Typically one of the old massive, heavy Stanleys. I have one that is over 30 years old and still good.
