Great toothpaste, difficult cap

I've been using this toothpaste lately. It's a great toothpaste, fresh, foams a lot. But the packaging is very difficult when the tube becomes more empty. The cap is the problem in combination with the very weak tube. When I try to take the cap off or put it on, the tube rotates along. It's really hard to get the cap on and off. In the beginning, you were able to put the toothpaste upside down and it stayed in good shape. Now it's difficult and I'll just leave the cap off. Do not buy!
