Any covered bowl will work as well. What you need is to keep the vegetables out of direct contact with the condensation moisture inside the container. That is why I rarely use bags any more for vegetables in the fridge, but even recycled sherbet containers work very well. It does need to be covered, and preferably airtight, or they'll dry out and wilt (though wilted veggies are perfectly edible, they just don't look as good or have as good a texture).
