Tohatsu gas tank

I have the 3.1 gal tohatsu plastic gas tank. I was 7/8 filled with fresh gas, with fuel line disconnected, for about a week. WHen I checked it, the tank sides were sucked in. I released the air vent, but the tank stayed that way even with the fuel filler removed. Why did this happen? How do I fix the tank?
 
You had the vent closed, and when it cooled, the contents contracted. In warm weather, they tank should return to normal.
