ABSTRACT:
A two-piece spout and stopper for thin, volatile liquids, including an adapter piece to be threaded onto the neck of a bottle and a spout piece which threads into the adapter piece. Vent and pouring holes are provided in widely spaced array. The threads are sealed but allowed to be wetted by the fluid when pouring liquid. The shape of the surfaces is such as to minimize surface adhesion or trapping of liquid when the spout is closed.
