Shirley = surely on this site, has been for at least a century. Some people, obviously with some sort of auditory malfunction, think that they are homophones when everyone knows a homophone is a pink iPhone 6.
Mostly Thermos or Stanley, usually with those push button pour stoppers. All mine have eventually leaked. The only one that hasn't is my original type Thermos with the bog standard stopper. It's still good for 8 to 9 hours.
