When u want to blow up your tires how do you take out the "coffee" out from the cup? I dont get it. Do you have to get the whole thing down?

hi Daniel. when you put them on you push the soft coffee part down on the valve, the hard cup comes down with it beciase it has a lip on the bottom. then if you take them off, the lip makes sure that this time the soft part comes along when you pull the cup. hope this makes it clear, if not let me know and i’ll try and explain better. happy pumping! :)
