Abstract: A drip preventive spill-proof spout comprised of a highly water-repellant elastomer material, such as natural or synthetic rubbers, the preferred material being silicone rubber. The spout is particularly adapted for use with wine bottles, the mouths of which are not standardized. The elastomeric quality of the device enables it to be fitted to a large variety of wine bottles. The spout comprises a funnel formed at an angle of approximately 45.degree. to a horizontal line, thus making for maximum efficient drop retention and return of the residue to the bottle. The angle of the funnel relative to the horizontal or the vertical creates or gives rise to a sharp pouring edge over which each drop of wine must pass when the wine is being poured from the bottle into a glass. This edge and the material from which this spout is made are critical to the operability of the present invention. The material, preferably silicone rubber, causes the wine, which is mostly water, to "bead up" on the surfaces of the spout.
