Abstract: The present invention relates to a security closure for bottles for liquor and the like having a neck, comprising a stopper cap having an end wall, a skirt, and a longitudinal axis X-X perpendicular to said end wall of the stopper cap, a security seal attached to said skirt, a groove in the outer surface of said neck axially positioned onto said neck, said sleeve being provided with an upper edge and said upper edge snap-fitting into said groove of the neck, stop means on said skirt radially extending towards said longitudinal axis X-X, said stop means providing a bearing surface for an abutment present on said sleeve.

Abstract: A non-refillable pour spout, for use in the neck of a bottle to prevent introduction of liquid into the bottle but permit liquid already within the bottle to be poured from the bottle in any direction, includes a pair of check valves in a liquid pouring duct and a third check valve in a separate air entry conduit which extends through the pour spout alongside the liquid pouring duct. The pour spout fits within the neck of a bottle, where it is retained sealingly by a plurality of flexible collars extending about the circumference of the pourer spout. A horizontal flange extends radially about the upper end of the liquid discharge tube, a small distance above the upper end of the air entry vent conduit, to protect the air entry vent conduit against introduction of liquid and to permit liquid to be poured in any direction without spilling into the open end of the air entry conduit.
