This is for all you UK cheep skates, first by a cheap plastic bottle with
a ball valve and remove the pipe.  Go to a chemist or home brewing shop
and buy a small sized plastic demijohn stopper with a hole in it.  Fit
the pipe into the stopper and the stopper into a standard UK milk bottle.
Total cost about a pound.  Chris.
 
PS when the bottle goes green give it back to the milk man and use a
clean one.
