Nov. 16, 1965 c. R. GOODSON POURING SPOUT FOR BOTTLE Filed June 11, 1964 INVENTOR. l/nwss J52 aaauso MZWZZ United States Patent 3,217,950 POURING SPOUT FOR BOTTLE Charles R. Goodson, Canoga Park, Califi, assignor to Pouring Spout for Bottle, a limited partnership, Canoga Park, Calif.

Filed June 11, 1964, Ser. No. 374,406 3 Claims. (Cl. 222484) This invention relates to pouring spouts for bottles and particularly liquor bottles and more particularly to a pouring spout which does not interfere with the closure of the bottle by the usual screw cap.

The principal object of the invention is to provide a pouring spout for bottles comprising a base element which may be fitted into the neck of a bottle in the manner of a cork and which includes an air inlet tube and an extendable pouring spout and which, further, while installed in the bottle, does not interfere with the closure of the bottle by the usual screw threaded cap.

Another object of the invention is to provide a pouring spout of the foregoing character and which additionally is capable of such economical manufacture that it may be regarded as a disposable item.

With the foregoing objects in view, together with such additional objects and advantages as may subsequently appear, the invention resides in the parts and in the con struction, combination and arrangement of parts described, by way of example, in the following specification of a presently preferred embodiment of the invention, reference being had to the accompanying drawings which form a part of said specification and in which drawings:

FIG. 1 is a perspective view of a pouring spout device constituting a presently preferred embodiment of the invention with the spout component thereof being extended as for use,

FIG. 2 is a top plan view of the device shown in FIG. 1 having reference to the attitude of the device as shown in FIG. 3.

FIG. 3 is a medial sectional view taken on the line 33 of FIG. 2 with the spout retracted to permit the closure cap to be applied to the bottle as indicated in broken lines,

FIG. 4 is a medial sectional view similar to FIG. 3 but with the spout component extended for use,

FIG. 5 is a sectional view taken on the line 5-5 of FIG. 3, and

FIG. 6 is a perspective view of a bushing accessory usable with the device to vary the rate of discharge of fluid through the pouring spout.

Referring to the drawings, the illustrated embodiment of the invention comprises a base element 1, a pouring spout component 2, and an air inlet tube 3. The base element 1 is preferably molded from a somewhat rubberlike plastic such as, for example, a suitable grade of polyethylene or equivalent material and comprising a cylindrical skirt portion 4 adapted to fit yieldingly tightly into the neck N of a bottle B, a thin circular head flange portion 5, adapted to engage the end of a bottle neck and provided with a shallow annular recess 6 of a diameter generally similar to the inner diameter of the skirt portion 4 and separated from the skirt portion 4 by an integral cross wall 7.

Closely adjacent to the inner wall face of the skirt portion 4, the cross wall 7 is provided with a bore 8 in which the air tube 3 is tightly fitted and secured by any suitable means. The air tube 3 may be of any suitable material and conveniently may be formed of a suitable length of extruded plastic tubing of sufiicient rigidity not to collapse when fitted (as by a force fit) into the bore 8. The tube is preferably of such length as to extend at least substantially the entire length of the bottle neck and into the body portion of the bottle itself as indicated in FIGS. 1, 3 and 4.

The pouring spout 2 is also preferably formed of a plastic of the same general characteristics as the base element 1 and comprises a short, curved tube preferably formed with a circumferential bead 9 at the outer end thereof. The spout fits tightly but slidingily in a hole 10 extending through the cross wall 7 and after insertion into the hole 10, the inner end of the pouring spout is flared outwardly, as at 11, by any appropriate means, as for example, by the point of a heated tool, to provide an enlargement sufficient to prevent the tube from being removed from the base element 1. Since both the base element and the spout are formed from yieldable material, they will yield sufiiciently to permit the curved portion thereof to pass back and forth through the hole 10 to the extent permitted by the bead 9 and the flared inner end 11. Preferably, the spout component adjacent the bead 9 and the flared end 11 is straight to conform to the axial line of the hole 10 to provide a tight fit when in either of the two positions it occupies.

Referring to FIG. 3, it will be noted that the head flange 5 is no greater in diameter than the outer diameter of the closure cap threads which engage the threads on the bottle neck, wherefore, the usual screw cap closure means C may be applied to close the bottle, the cap serving to press the flange 5 tightly against the end or" the bottle neck and thus the flange serves also as a gasket eliminating the gasket usually associated with screw caps. Also it will be noted that the bead 9 fits within the recess 6 and is of such length as to be firmly seated on the bottom of the recess by the pressure of the cap on the outer end of the tube. Preferably, the bead 9 includes a tab element 12 projecting radially therefrom offering a gripping means for pulling the spout out for use. For those uses in which it is desired to dispense fluid or liquor through the pouring spout at a slower rate, bushing elements such as shown at 13 in FIG. 6 may be inserted in the inner end of the pouring spout.

Thus there has been provided a pouring spout arrangement for bottles from which the contents are dispensed in small amounts and in which splashing due to the intermittent entrance of air is to be avoided and which is of such economical form that it can be provided with the individual bottles and thrown away with them.

While in the foregoing specification there has been disclosed a presently preferred embodiment of the invention, the invention is not to be deemed to be limited to the precise details of construction thus disclosed by way of example, and it will be understood that the invention includes as well, all such changes and modifications in the parts and in the construction, combination and arrangement of parts as shall come within the purview of the appended claims.

I claim:

1. An extendible pouring spout means for a bottle having an exteriorly threaded neck for reception of a screw threaded closure cap; said pouring spout means comprising a cylindrical base element formed of a resilient material and adapted to yieldingly closely fit the interior of a bottle neck in the manner of a cork, an integrally formed bottle end engaging flange on said base element of a diameter not greater than the root diameter of the screw cap threads, an air inlet means carried by said base element and extending therethrough inwardly toward the interior of the bottle, a second bore extending through said base element generally parallel to said first bore, and a pouring spout tightly slidingly mounted in said second bore and having means at each end thereof engageable with the ends of said second bore operative to limit the extent of said sliding movement in said second bore.
