96 Honda LX...antifreeze disappearing act, but no leak in the bottle itself...what gives?

Help!!!

My temp gauge spikes to the red after a mile or so of driving and
today it started smoking under my hood, so I pull over and I notice
that the smoke wasn't coming from my engine...it was coming from the
front right hand side of my car, close to the antifreeze contanier.

So, I check the antifreeze and notice that it's empty. I filled my
car with the antifreeze water mix, but after about 5 minutes of
driving my gauge spikes up again. I jump out and check my antifreeze
and notice that it's almost half gone.

I took out the bottle to check for leaks and there wasn't any. Does
anyone have a clue where the antifreeze is going and how do I get it
to stay, so that my car doesn't over heat?

Thanks in advance...
