Thermos is recalling about 8.2 million jars and bottles after receiving reports that customers are being injured by product stoppers, U.S. safety regulators said. The recall follows customer complaints that, in some cases, the stoppers “forcefully ejected” from the containers and struck people. Regulators report that some injuries result in permanent vision loss. Thermos also states that a key pressure relief mechanism is missing from some affected products, which it says can contribute to unsafe pressure conditions. The recall covers specific models identified by the company and regulators, with Thermos notifying customers and advising them to stop using and follow instructions for return or repair, depending on the product. The company’s actions are aimed at reducing further risk to consumers while investigating the specific manufacturing and design issues tied to the recalled containers.
