In addition to what Dan has mentioned, I use the Libby type glass jars for storage. The lids generally have a soft plastic seal and snug real tight when placed on the jar. You can see an example here:

Look for Libby 70995 15oz at the bottom of the page.

You can find these at a very cheap price at your local thrift shop or 99 cent store (hey, they're actually 99 cents too!). Mine will hold around 3 oz each, and the one I recently purchased at the Salvation Army store cost $2.95 and easily holds 8oz+.

Hope this helps you...
