SOUTH BEND, Ind. -- On Thursday, the Stanley company issued a recall on 2.6 million of their drink cups, specifically the Switchback and Trigger Action travel mugs.

The U.S. Consumer Product Safety Commission says these mug's lid threads can shrink when exposed to heat and torque, causing the lid to detach during use, posing a burn hazard.

Anyone with one of the recalled mugs should replace it immediately. 

"The recalled double-walled mugs were sold in a variety of colors including white, black and green, in 12 oz., 16 oz. and 20 oz. sizes with a polypropylene lid," the USCPSC said. "The Stanley logo appears on the front and bottom of the mug."

The recalled mugs have one of the following product identification numbers printed on the bottom of the mug:

Switchback

• 12 ounces -- 20-01437
• 16 ounces -- 20-01436, 20-02211

Trigger Action

• 12 ounces -- 20-02033, 20-02779, 20-02825
• 16 ounces -- 20-02030, 20-02745, 20-02957
• 20 ounces -- 20-02034, 20-02746
