To open an Ubbi diaper pail, press the large, round button in the center of the lid firmly until you hear a click, then lift. The Ubbi does not twist, slide, or require a key, its single-button child-proof lock releases the internal latch when pressed straight down.
That click is the latch disengaging. Miss it, and you’re just pushing on a sealed steel lid. The design is simpler than most parents expect, which is why the first attempt often fails, they look for a slide or a twist that isn’t there.
What follows: the exact press-and-lift sequence, what to do when the button sticks (usually a bag liner caught in the seal), and the two maintenance steps that keep the mechanism working smoothly for years.
Key Takeaways
- Press the center button straight down until it clicks, force applied at an angle won’t release the latch.
- A stuck lid is almost always a diaper bag liner pinched in the odor-lock gasket; pull the liner back from the rim.
- The Ubbi uses standard 13-gallon kitchen trash bags; specialty liners can be too thick and jam the mechanism.
- Clean the stainless steel interior and lid gasket monthly with a vinegar solution to prevent sticky residue from hardening on the latch.
- Never lubricate the button or latch with oil-based products; a dry silicone spray on the hinge points once a year is the only safe maintenance.
The Exact Button-Press Sequence
Find the large, round button in the middle of the lid. Place your thumb flat on it. You are not tapping it or sliding it. You are pressing it directly downward, toward the floor.
The Ubbi’s latch mechanism is a simple spring-loaded cam. Pressing the button compresses the spring and rotates the cam, pulling the internal hook back from the rim of the pail. The audible click is the hook clearing the rim.
You’ll feel initial resistance, then a distinct click as the internal latch retracts. That’s your signal. Immediately lift the lid by the front edge. If you don’t hear the click, you haven’t pressed hard enough or you’ve pressed at a slight angle. Reset and press again, straight down.
Do not try to slide the button forward or backward. Do not twist the lid. Those actions work on competitors like the Diaper Genie; they do nothing on an Ubbi and can feel like the pail is broken. This single motion is the entire process for using the Ubbi.
| Action | Correct Method | What Happens If You Do It Wrong |
|---|---|---|
| Press | Thumb flat, direct downward force | Angled pressure binds the cam; no click, lid stays locked |
| Listen | Wait for the audible click | Lifting without the click strains the hinge; lid may partially open then snap shut |
| Lift | Lift from the front edge immediately after the click | Delaying allows the spring to re-engage the latch, re-locking it |
When the Lid Won’t Budge: The Usual Suspects
You pressed. You heard the click. The lid still won’t open. This isn’t a broken latch, it’s almost always an obstruction.
First, check the bag. The most common culprit is a standard kitchen trash bag that has slipped down or been pushed inward when you tossed a diaper. The plastic gets pinched between the stainless steel rim and the rubber odor-lock gasket on the lid. That seal is incredibly tight by design, and a thin piece of plastic can create enough friction to glue the lid shut.
Where this goes sideways: A bag liner caught in the gasket. You’ll press the button, hear the click, but the lid feels suctioned shut. If you force it, you tear the bag and leave a shred of plastic jammed in the seal that causes the same problem tomorrow.
Fix it before you force it. Press the button to unlock it, then use your fingers to reach under the lid’s front edge. Feel for the bag. Gently pull the entire bag liner away from the inner rim, working your way around the pail. You’re trying to free the plastic from the rubber gasket. Once it’s clear, the lid will lift freely. This is a core part of proper bag installation.
If the button itself feels stiff or won’t press, inspect the hinge area for dried formula, sticky wipes residue, or hardened diaper cream. Gunk here can impede the button’s return spring.
Ubbi vs. The Others: Why the Mechanism Confuses People

If you’re used to a different pail, your muscle memory is wrong. This is the main reason people think their Ubbi is broken on day one.
Most diaper pails use a twisting action to seal and lock. The Diaper Genie requires a foot pedal and a twisting motion to cinch and cut bags. The Munchkin Step uses a step pedal and a rotating lid. Your brain looks for a similar mechanical action. The Ubbi doesn’t have one. Its innovation is simplicity: a steel pail with a locking lid that uses any bag. This is a key difference when comparing diaper pails.
The child-proof lock is also a point of confusion. It’s not a separate device or a key. The button itself is the lock, pressing it requires enough deliberate force that a toddler’s casual slap won’t trigger it. This is a safety feature, not a complexity.
| Pail Type | Opening Action | Bag System | Common User Mistake |
|---|---|---|---|
| Ubbi | Press center button, lift lid | Standard trash bags | Trying to twist or slide the lid |
| Diaper Genie | Step pedal, twist lid | Proprietary refill cassettes | Expecting a button press |
| Simple Step Can | Step pedal only | Standard bags | Looking for a locking mechanism |
Maintenance That Prevents Problems

The Ubbi is stainless steel, so it won’t absorb odors. But the mechanism can get sticky. A monthly wipe-down keeps it working like new.
You need to clean the Ubbi pail thoroughly. Empty it. Mix a 1:1 solution of white vinegar and water. Dampen a cloth, don’t spray directly into the hinge or button. Wipe the entire interior, then focus on the rim and the rubber gasket on the underside of the lid. This removes the milk residue and sticky sugars from wipes that harden into a glue-like film. That film is what eventually makes the button stick.
For the hinge and button mechanism, use a dry toothbrush to gently dislodge any visible debris. Do not use oil, WD-40, or soap-based lubricants. They attract more dirt and can degrade plastics. If the hinge feels gritty, a single drop of dry silicone spray on a cloth, wiped on the hinge pin, is the only safe lubricant. Do this once a year at most.
This routine is more intensive than general diaper pail cleaning for a simple can, but it’s what preserves the Ubbi’s function. A clean pail is also the first step in any plan to deodorize a diaper pail.
Choosing the Right Bag (It Matters More Than You Think)
The Ubbi’s biggest selling point is using any bag. This is true, but not all bags are equal. The wrong bag creates the jams we just discussed.
You want a standard, flexible 13-gallon kitchen trash bag. Drawstring bags are fine. Avoid “thick” or “contractor-grade” bags. The extra-thick plastic doesn’t conform as easily to the pail’s shape and is more likely to buckle and get caught in the seal. Also avoid bags that are too small; they pull down too tightly and are harder to position cleanly over the rim.
When you install a new bag, pull it up so the top edge folds over the entire outer rim of the pail. Don’t just drop it in. That folded-over cuff is your insurance policy against the bag slipping down into the path of the gasket. A well-installed Ubbi diaper pail liner is a solved problem.
Troubleshooting a Stubborn Pail
Let’s run through the checklist if the standard fix doesn’t work.
- Button clicks, lid stuck. Confirm the bag is clear. Then, press the button and have a second person gently pull the lid up from both sides simultaneously. Sometimes the latch releases unevenly.
- Button won’t press. Inspect for physical debris in the button collar. Use a toothpick to clear it. Check for a deformed lid, if the pail was dropped, the steel rim might be bent, misaligning the latch.
- Lid pops open on its own. This means the latch hook or the strike plate on the rim is worn. This is rare with normal use. Contact Ubbi customer service; the lid assembly may be under warranty.
- Persistent odor despite cleaning. Odor is usually in the bag material itself or the gasket. After deep cleaning, sprinkle baking soda in the empty pail before inserting a new bag. For a stronger solution, consider dedicated diaper pail deodorizers.
If your Ubbi is beyond repair and odor is the main issue, this experience will inform your search for the best odor control pails next time.
Frequently Asked Questions
Why is my Ubbi diaper pail so hard to open?
It’s almost certainly a standard trash bag liner caught in the tight rubber seal. Press the button to unlock, then pull the entire bag away from the inner rim before lifting. A bag pinched in the gasket creates immense friction.
Can you open an Ubbi diaper pail with one hand?
Yes, but it requires technique. Press the center button with your thumb, then use the same hand to hook your fingers under the front lip of the lid to lift it. It’s easier if the bag isn’t overly full, creating less suction.
How does the Ubbi child lock work?
The lock is the button mechanism itself. It requires a firm, direct press with deliberate force to retract the internal latch. A toddler’s slap or casual push typically doesn’t apply enough focused pressure to trigger the release, making it child-resistant.
What kind of bags does the Ubbi pail use?
The Ubbi is designed for flexible, standard 13-gallon kitchen trash bags. Avoid overly thick or rigid bags, as they don’t conform well and are more likely to cause jams. The ability to use cheap, generic bags is a primary benefit of a diaper pail like the Ubbi.
Before You Go
Open the Ubbi by pressing straight down, listening for the click, and lifting. When it sticks, check the bag liner first. Keep it clean, use the right bags, and the steel workhorse will last through multiple kids. Its simplicity is the point, no proprietary refills, just a sealed container for the mess. Now you know how to work the latch, you can focus on what actually matters: keeping the nursery fresh.
