Thermos recalls 8.2M Stainless King Food Jars and Sportsman Bottles after stoppers forcefully ejected under fermentation pressure, causing permanent vision loss in 3 users.
Key Takeaways
Affected models: SK3000 (16oz) and SK3020 (24oz) Food Jars made before July 2023, and all SK3010 (40oz) Sportsman Bottles.
Root cause: stoppers lack a pressure relief function; perishable food or beverages stored long-term build pressure that ejects the stopper on opening.
27 injury reports total; 3 consumers suffered permanent vision loss after stopper struck their eye.
Sold at Target, Walmart, Amazon, and Thermos.com from roughly March 2008 to July 2024 for ~$30.
Remedy: SK3000/SK3020 owners send photo of disposed stopper for replacement; SK3010 owners return bottle via prepaid label at support.thermos.com.
Hacker News Comment Review
Commenters note the failure mode is user-driven: fermenting perishables inside a sealed, pressure-relief-free container is the proximate cause, not a manufacturing defect per se.
The core engineering gap identified is the absence of a passive pressure vent in the stopper design, a standard safety feature that would have prevented ejection entirely.
