I have a close relative that works for the company that invented the valves in them. They used to make stuff like keyboard membranes, until China ran the price down too low to compete. An employee figured out how to make a cheap valve using most of the same tooling and the company patented it. Someone in sales got Pepsi to put them in All Sport bottles, and it saved the company. Now the people in sales try to solve everyone's problem with them.
