Abstract
An apparatus for capping a jar includes a plastic flat plate having a top and a bottom and a depending skirt with internal threadings and a hole in the flat plate. A measured liquor pouring spout inserted through the hole in the plate has a channel for flow of liquid and a cap sized and shaped to cover a liquor bottle with a lower skirt that abuts the top of the flat plate. The spout has a lower stem with a first radial flange under the cap abutting the top of the flat plate and a second radial flange under the cap spaced below the first radial flange. A gasket on the lower stem below the flat plate closes portions of the hole that surround the lower stem and secures the stem in position by fitting between the second radial flange and the bottom of the flat plate.
