Self-Sealing Water Balloons & Patent Claims? Absolutely.
It started in the garden: kids laughing, running, and throwing what looked like futuristic water balloons. No tying. No spills. Just dip, fill, toss.
Naturally, I looked it up.
Turns out there’s more to this summer fun than meets the eye — like US11141671B2 (US11141671B2 - Self-sealing balloons and related components and methods of manufacturing - Google Patents), a patent protecting a surprisingly clever combination of elastic collars, internal valve balls, and methods for pressure-based self-sealing. It’s a smart piece of IP, covering not just the product but how it's made and used. Variants extend into everything from party kits to large-scale fluid storage.
The result? A solid patent position that blocks more than knock-off toys. This is consumer tech backed by broad mechanical and method claims.
But one thing caught my eye as a parent: those small balls—called “valve bodies” in the patent. They're sometimes biodegradable. Sometimes not. And in the chaos of summer play, they don't always land in the bin.
🧠 A fun invention, strong patent... but as always: it’s not that simple.
