large popper bottle sniffer cap

This is a sniffer device for use on a large popper bottle (30 ml).  This is the large rectangular kind and specifically I think it was measured off of a 30 ml jungle juice bottle.

There are three parts that fit together and screw onto the bottle.

The slider part fits in a slot and can seal the fume and operates one handed.

I do not find this suitable for storage, only for use, since it doesn't seal up perfectly.  You can put the quantity you want to use at a time into a spare bottle and put this on top.
