Recently these (Pictures) containers have arrived on the scene in varioous sizes. I use them for many things, particularly when camping to stop food from leaking. May I suggest they would make good freezer containers, since they are well sealed. Here is a picture of the typical containers. http://www.durgan.org/ShortURL/?QJPVN 10 August 2008 Sealed container with gasket I have found them in various big box stores. Walmart has a few, and Zellers. Some are better than others. I got my first package last summer in some store in Salmon Arm, BC. Now I sort of look around for them in the few stores that I visit. They still aren't widely available. Most stores are selling the press on top type without a gasket, which have been useless, for years. http://www.smartgoods.ie/ Here is one that I don't particularly like. http://www.locknlock.com.au/faq.htm Lock and Lock http://www.organize.com/lolofostco.html http://www.starfrit.com/Products/kit...spx?sc_lang=en
