Spirits bottle has extra liquid contained in bottle stopper with opaque collar around neck of bottle

摘要

The spirits bottle has a body (10) and a stopper (11) of transparent material. The stopper can be hollow to hold a quantity of the same liquid (A) as that in the bottle. The neck of the bottle is surrounded by an opaque collar (13) so that the seal between the liquid in the bottle and stopper is masked to give an illusion of the liquid surface (14) in the bottle is the same as that in the stopper.
