Mama to Jaxon Sage, born 8/11/12, in the backseat of my car.
I would think that the best option would be a large wetbag, but other than that, a small rubbermaid- type container (maybe 2 gallons) would work too.

Our day care was fine with a drawstring wetbag (we were the second ones to use cloth, I believe). I've heard that some people use those plastic buckets that cheap ice cream comes in. The lids are fairly easy on/off and if it gets funky, you find someone to give you another one!

Announcing the arrival of Clara in August 2013!
I used a wetbag, but if they insist on a closed container I found that the 5gal buckets you can buy at home improvement stores and that my costco laundry detergent came in worked really well with my pail liners.
I found the "waterproof" drawstring bags in the sporting goods section of walmart that were not 100% waterproof like a real wetbag is. I used it for a pail liner for a step on trashcan, but they fit really well into the 5gal buckets too.
I started to replace the drawstring with a piece of elastic which made things easier.
I think they ran about 5bucks each. You could bring in a pail like that with a lid and just take the bag home with the used diapers.....and wash the pail periodically.
I usually put a wipe dotted pretty heavily with tea tree oil in the bottom of my pails under the liner and switched those out frequently.
