Abstract

A pouring stop for bottles and other liquid containers. The stop comprises a spout, having a pouring lip, and cooperating with a collecting space around the spout. The spout is provided with a pouring tongue attached to the inner side of the spout, extending initially outwardly parallel to the spout axis and subsequently being curved in the same direction as and spaced from the pouring lip. The lip acts to draw the last drop back into the bottle.

Claims

1. A pouring stop for bottles comprising, in combination:

a plug body having a base portion adapted to be inserted in the opening of a container and having a spout portion projecting axially outwardly thereof, said spout portion presenting an inner wall surface defining a channel through which a stream of liquid may flow and terminating in a pouring lip curving away from the axis of the body and over which the stream of liquid issues in contact therewith; and

a narrow, blade-like tongue having an inner portion extending axially of said channel and defining an upraised rib along said inner wall surface of the spout portion and having an outer portion projecting outwardly beyond said pouring lip and curving away from the axis of the body to terminate in a tip disposed in axially spaced relation to said lip so as to be located within the stream of liquid issuing over the lip.

2. A pouring stop according to claim 1, wherein the tongue ends in a direction substantially perpendicular to the axis.

3. A pouring stop according to claim 1, in which the spout on at least a part of its length slightly widens outwardly, wherein the tongue is applied along the wall of the widening part of the spout, the tongue itself on its side turned toward the axis extending parallel to this axis.

4. A pouring stop as defined in claim 1 wherein said plug body includes an intermediate wall portion defining a concave outer face and having a central opening from which said spout projects, said spout being of U-shaped cross section to allow liquid to drain toward and to said central opening when the plug body is upright.
