All you have to do is get two containers, one open and one backup. When you use up the first buy another one the next time you go grocery shopping.
That's exactly why this is useful. It's something I forget to buy at the store because I run out so rarely. Right now while I'm doing my laundry if I notice I'm below about a third I'll hit the button.
Before I'd almost always realize I was out of detergent mid-washing, undoubtedly the night before some important meeting, and have to run to the store in the middle of the night.
Leave the empty bottle by the doorway or in your car or something until you remember.
