I hate to say it but, I need one of these ...I work in healthcare, my job doesn't provide creamer, just coffee. I started bringing my own creamer, big bottle, put a sticky note with my name on it, put it in the employee fridge. By the next day, the bottle was completely empty when I went to use it. I tried buying a smaller size and hiding it, with my name on a sticky note on it, same result. I definitely don't mind sharing, I shared with the people on my shift, but can't afford to provide creamer for everyone.

The best idea is probably single-serve packs, but one alternative is to get a combination lock bottle stopper. They’re made for whiskey bottles, so you could use an empty whiskey or wine bottle, put in as much creamer as you might need for a few days, and use the lock stopper to seal it. 

Probably a good idea to take the label off if you’re going to do that though. Or just buy a glass bottle that doesn’t look like it had booze in it.
