Easy as 1, 2 3, just STEP on our foot pedal AND DROP the soiled diaper through the trap door. No squishing, twisting or cramming. A childproof lock keeps curious toddlers out. Continuous liners allow you to empty the pail whenever you want, using only as much refill as you need. Simply cut the refill with the kid-safe cutter located inside the access door, discard, and tie a new knot in the remaining bag. You don’t need to waste a full bag to empty a partially-full pail. There is an effective triple odor control that keeps smell in the pail. First, the spring-loaded trap door shuts immediately after the diaper passes through. Next, rubber gaskets on the trap door and the top lid tightly seal odors inside the pail. Finally, the refillable liner helps neutralize odors with a pleasing baby-powder scent. Because all our pails are made with closed-cell ABS plastic, they cannot absorb odors like cheaper plastics, will not dent, and are scratch- and fade-resistant.
