When a pump hand lotion bottle is too empty to pump the thick lotion up, there's usually far too much lotion left to throw the bottle away. The red line shows how much lotion can be left in the bottle when the pump gives up.
It's easy to remove the pump and close off the top to enable the bottle to be turned upside down. If you get the same brand there is no need to fix up a new top each time, just store your closed off top until needed.
Step 1: Take apart the pump
This bottle was easy to dismantle. After taking the pump out of the bottle, I just gripped the top and the inside with two pairs of pliers and pulled the mechanism apart.
