Yes — almost certainly. Every 2-pack and 4-pack ships with a Small and Medium cap, and together those fit about 90% of bottles, from small face creams to conditioner and lotion bottles. On top of that, you also get a FREE Large cap built for oversized bottles — bulk-size shampoo, conditioner, and lotion jugs.

No. Every cap seats onto a gasket for a leak-proof seal, and the wide base keeps the bottle standing upside down without tipping.

Yes — that's exactly what it's built for. Thick, slow-moving products are the ones that get trapped worst in pumps, and gravity feeding them straight to the opening is where WasteNot shines.

Twist the cap off, rinse the cap, insert, and gasket with warm water, and let them air dry before moving to the next bottle. That's it.

"I was taught me to never throw anything away. I've spent my whole life cutting bottles open to scrape out the last of the lotion. This little cap does all that for me now. I just flip it upside down and let it sit. No mess, no knife, no wasted money. Wish I'd had this 30 years ago."

The Part of the Bottle You Can't Reach? We Call It the Dead Zone.

It's a design flaw — and it's been quietly stealing from you every single time you've thrown a bottle away.

A peer-reviewed 2025 study measured it directly: pump dispensers leave up to 26% of thick product trapped inside. For one 500 mL hand-cream bottle, that residue was enough for about 13 more applications — thrown straight in the trash.

The Gravity-Seal Drain: A Different Way to Empty a Bottle

Spatulas, razor blades, and balancing bottles upside-down in a cup all try to chase the product. WasteNot does the opposite — it removes the pump from the equation and lets gravity bring the product to you.

1. Screw It On

1. Screw It On

Take off the pump and twist on the correctly-sized WasteNot cap. The gasket seats against the bottle for a leak-proof seal.

2. Flip & Seal

2. Flip & Seal

Stand the bottle upside down on the cap's wide, stable base. Gravity immediately starts feeding every last drop toward the opening — the Dead Zone never gets a chance to form.

3. Drain & Dispense

3. Drain & Dispense

When you need product, it's already waiting right at the opening. No shaking, no pounding, no scraping your knuckles raw.

Because it replaces the pump instead of fighting it. See the difference on the very first bottle — not after a dozen tries.

Made to Fit the Bottles You Actually Own

The single biggest complaint about the old flip-caps is simple: “they were all the same size and didn't fit any of my bottles.” We fixed that at the source.

  • Small + medium fit ~90% of standard bottles — shampoo, conditioner, body lotion, foundation, ketchup, and more
  • Large is made for the big stuff — warehouse-size lotion, shampoo, and conditioner containers
  • A gasket in every cap creates a leak-proof seal — store bottles inverted with zero drips
  • A wide, stable base means the bottle stands on its own, upside down, without tipping

It Pays for Itself the First Time You Finish a Bottle You'd Have Thrown Out

The residue in a single 500 mL lotion pump measured out to about 13 more applications. Now multiply that across every bottle of shampoo, conditioner, lotion, and condiment your household goes through in a year. That's real money you already spent — going in the trash.

Why I built WasteNot™

I didn't set out to start a company. I grew up in a small town in Minnesota where money was tight and nothing got wasted — my parents drilled it into me that if you paid for something, you used all of it. Not most of it. All of it.

So it drove me a little crazy every time I threw out a bottle that clearly still had product in it. I tried everything — the spatulas, cutting the bottles open with a razor, propping them upside down until they tipped over and made a mess. It was ridiculous. I was fighting the bottle to get back something I'd already paid for.

Then I found out it wasn't just me: researchers had measured it. Up to a quarter of thick product gets stranded in the pump. That was the last straw. I decided the fix shouldn't be a life hack you fight with — it should be built right into the cap.

I've passed the “waste nothing” rule down to my kids and grandkids. Now it's built into every cap we make.

Your Questions, Answered

Yes — almost certainly. Every 2-pack and 4-pack ships with a Small and Medium cap, and together those fit about 90% of bottles, from small face creams to conditioner and lotion bottles. On top of that, you also get a FREE Large cap built for oversized bottles — bulk-size shampoo, conditioner, and lotion jugs.

No. Each cap seats on a gasket for a leak-proof seal, so you can store bottles fully inverted without drips.

No. The cap has a wide, flat base designed to stand the bottle upside down on its own — no balancing, no flower pot, no tipping.

The gaskets are durable and built to last, and replacements are inexpensive if one ever gets lost.

Each cap costs about $4. On one large lotion bottle, getting back 25% more product is worth $6–$8 — more than the cap paid for. Add that up across every bottle in your house over a year, and it's easy to see why this pays for itself fast.

Yes — thick, slow products are exactly the ones that get stranded worst in pumps, and they're where gravity feeding makes the biggest difference.

Rinse the cap, insert, and gasket with warm water and let them air dry between bottles. The caps are BPA free and dishwasher safe.

A small number of uncommon neck sizes and specialty pumps won't fit the three included sizes. If yours isn't covered, our guarantee has you fully protected.

No More Banging, Scraping, or Cutting Bottles Open.

One twist-on cap turns every "empty" bottle into a few more weeks of use.
