A specially designed pail for diapers is going to offer significant odor containment advantages over a normal kitchen trash container. A product specifically made for diaper containment is designed to tightly seal in the odors created by baby in a way that normal kitchen trash cans cannot. However, simply sealing the pail tight isn't enough. Just as important is what happens when you open and close the pail to make a new deposit. The best products provide a specially designed mechanism for inserting a dirty diaper in the pail that minimizes the amount of stinky smell that escapes with each use. In addition, the best pails have a design that makes it easy to change a full bag without releasing excessive odors.
