You’ve probably seen these around, even if you weren’t sure what they’re called: shaker cups or bottles are usually BPA-free plastic or metallic drinking containers, which might look somewhat like just a regularstainless steel bottle. They usually have a flip lid that attaches tightly to prevent leaks or spills, and might come with a built-in straw or a simple flap opening.
