it works for me, although mine is a large liquid storage container tank rather than a box. Whenever we process really heavy stuff in a session T asks me how much of the emotion I'm feeling can I handle feeling until our next session. Then anything excess get's put in the tank. I visualize my emotions flowing into the tank like a stream of liquid.

It's wierd, but it works really well for me. But then again, I'm really good at dissociation (too good - it's a problem) so shutting stuff off is just really natural for me.
