Thermos class action lawsuits overview:
- Who: Four consumers filed three separate class action lawsuits against Thermos LLC.
- Why: The plaintiffs claim Thermos concealed a stopper defect that allows pressure to build inside its jars and bottles, causing the stoppers to forcefully eject.
- Where: The Thermos class action lawsuits were all filed in Illinois federal court.
Three new class action lawsuits allege Thermos sold food jars and beverage bottles with a defective stopper. The lawsuits claim the stopper lacks an adequate pressure-relief mechanism, letting pressure build inside the sealed container.
Plaintiff George Euripides claims the stopper on his Thermos Stainless King food jar suddenly ejected near his face after internal pressure built up, leaving him afraid to use the product again.
According to plaintiff Linda Moynihan, Thermos marketed the products with a “Dura-Guard pressure relief stopper that enhances insulated performance and removes easily.” However, all four plaintiffs argue the Thermos stopper could eject with enough force to cause impact injuries, lacerations and eye damage.
Moynihan bought a Stainless King food jar from Amazon in December 2023 and claims she would not have purchased it, or paid less, had she known of the defect.
Meanwhile, plaintiff Katie Pence, who purchased a Stainless King jar at an Ohio Walmart, makes similar claims, alleging that “food and beverage container products containing the defect are in no way safe for use and are entirely worthless.
Plaintiff Daniel Meaney says he also would not have bought his Stainless King jar had he known of the Thermos stopper risk.
Each lawsuit seeks to represent a nationwide class alongside three state subclasses in New York, New Jersey and Ohio, respectively. All three class actions demand a jury trial.
Thermos stopper recall covered 8.2 million jars, bottles
The Thermos stopper defect triggered a recall on April 30, 2026, of about 8.2 million units, roughly 5.8 million Stainless King food jars and 2.3 million Sportsman bottles, sold at Target, Walmart, Amazon and Thermos.com from March 2008 through July 2024.
According to the recall notice, Thermos received at least 27 reports of the stopper forcefully ejecting and striking consumers, including three cases of vision loss injuries.
The remedy differed by product: Stainless King owners were to discard the stopper and send Thermos a photo of it, while Sportsman bottle owners had to return the entire bottle on a prepaid label before Thermos ships a replacement.
The Thermos class action lawsuits allege this remedy was inadequate because it offered no cash refund and shifts the burden onto consumers to identify, package and return their own products, years after Thermos allegedly knew of the defect.
The three lawsuits allege violations of New York and Ohio consumer protection statutes, the New Jersey Consumer Fraud Act, breach of express and implied warranty, negligence (including negligent design and failure to warn), negligent misrepresentation and unjust enrichment.
