Unger, Louisville, Ky., assignor to Joseph E. Seagram & Sons, Inc., New York, N.Y., a corporation of Indiana Filed Mar. 10, 1958, Ser. No. 720,116 Claims. (Cl. 21S-22) The present invention relates generally to non-refillable containers for liquids and more particularly to a bottle closure of the type intended to prevent refilling of a bottle to which it is applied.

It is a general-object of the present invention to provide an improved bottle closure which facilitates dispensing of liquid contents, which is operative to close the bottle to which it is applied when the -bottle is in upright position, and which effectively prevents refilling.

Another and related object of the invention is to pro-- vide a bottle closure constructed and arranged for permanent attachment to theneck-otf a bottle and which is operative to permit pouring of the contents from the bottle without dribbling and without undue impairment of flow rate, to permit the entire contents to be dispensed and to inhibit tampering so as to prevent refilling regardless of bottle position.

It is a further object to provide an improved bottle closure embodying the foregoing features which is of exceedingly simple construction involving few parts, which permits of economical manufacture from readily available materials, and which is not likely to fail in operation.

The objects of the invention thus generally set forth, together with other objects and ancillary advantages are attained by the construction and arrangement shown by Way of illustration in the accompanying drawing, in which:

FIGURES 1 and 2 are vertical sections, taken at right angles to each other, through a bottle closure embodying the features of the present invention and showing the same in place upon the neck of a bottle.

FIGS. 3 and 4 are transverse sections taken in a common plane but looking in opposite directions as indicated by the lines 3 3 and 4 4, respectively, in FIG. 2.

FiG. 5 is a transverse section taken substantially in the plane of line 5 5 in FIG. 2.

FIG. 6 is a vertical section like FIG 2, but which has been somewhat simplified, illustrating various positions that might be assumed by a tampering wire.

While the invention is susceptible of various modifications and alternative constructions there is shown in the drawing and will herein be described in considerable detail a preferred embodiment. It is to be understood, however, that it is not thereby intended to limit the invention to the specific form shown and described. On the contrary it is intended to cover all modifications and alternative constructions coming within the spirit and scope of the invention as expressed in the appended claims.

Referring more particularly to the drawing, there shown for purposes of illustration is a bottle closure generally designated 10 applied to the neck 11 of `a bottle. The bottleneck 11 terminates in a constricted throat 12 which, as shown, is fashioned to provide external screw threads 13 for accommodating a complementally threaded cap 14. The throat portion 12 merges with the remainder of the neck 11 in a manner providing an internal shoulder 15.

The bottle closure 19 includes a body 16 of generally cylindrical for-m having an external diameter slightly less than the internaldiameter of the throat 12 of the bottle neck 11 so as to permit of insertion therein. At its upper end thebody 16 is provided with an external or circumferential shoulder 17 which is adapted to overlie the outer end of the bottle neck 11 and thus limit inward movement ldl@ Patented Jan. 3G, lg

of the bottle closure with respect thereto. Desirably the body 16 is provided with a gasket 1S of compressible material and preferably of inverted L-shaped half-section. The gasket 18 is disposed about the upper end of the body 16 adjacent and beneath the shoulder 17. Upon insertion of the body 16 within the throat 12 the gasket 18 is compressed into fluid-tight sealing relation between the bottle throat and the wall of the body, and between the underside of the body flange 17 and the outer end of the bottle neck. The body 16 has a stepped bore 19 therethrough. Thus the bore has an enlarged outer end portion 19a, an intermediate portion 19b of lesser diameter than that of portion 19a, and a lower end portion 19a of a still smaller diameter.

To facilitate dispensing liquid contents from the bottle the closure 10 is equipped with a spout 2t). The spout is preferably of generally cylindrical shape having a bore 21 therethrough. To assist in `directing the stream of liquid during pouring and to prevent dribbling when a pouring operation has been completed, the spout 2G has a 4lip 22 formed at one side of its upper end. The lip terminates in an outwardly-projecting, sharp cuto edge 22a for the purpose not only of directing fluid being poured therefrom but also for the purpose of breaking the stream of poured liquid upon completion of a pouring operation. The inner surface of the spout is smoothly rounded in a downward direction to direct droplets of the liquid contents back down the spout 20 when the bottle is returned to an upright position.

The bottle and the closure device are sealed against leakage during shipment and when not in use by a liner 23 ywithin the cap 14. The liner, as shown, is formed of slightly compressible material such as paper, cork or the like. Preferably the liner is coated with a liquid resistant lm 23a. Thus when the cap 14 is applied to the neck of the bottle the liner is drawn into seating engagement with the outer end of the spout Ztl, and leakage is thereby precluded even if the bottle should be maintained in an inverted position.

The lower end of the spout 20 is adapted for intimate engagement with the body 16. For this purpose its lower end is conformed to the upper end of the body, being complementally dimensioned to be snugly received therein.V Thus adjacent its lower end the spout has a peripheral flange 24 thereon which ts into an annular recess 17a formed in the body shoulder 17. While the parts can be cemented or otherwise fastened together, desirably the body and the spout are formed of thermoplastic material, and a permanent union can be effected simply bythe application of heat.

In order to close the bottle when it is in an upright position and to prevent refilling, the instant closure incorporates valve means. Preferably the valve means is of the ball-check type which readily performs the foregoing functions and at the same time minimizes impairment of dispensing flow rate. Also this valve form substantially precludes failure in operation. The illustrative device includes a valving element or ball 25 which is disposed within a chamber defined by the intermediate portion 19b of the valve body 19. The lower end portion 19t` of the body bore 19, as hereinbefore noted, is of a smaller diameter than that of the intermediate portion 19b thereby forming at the junction between them a transverse annular shoulder 26. The ball 25 is is a diameter slightly greater than that of the lower end portion 19C of the body bore 19, and thus the inner edge of the shoulder 26 defines a circular seat for the ball. Preferably `the diameter of the lower bore portion 19e is only slightly less than that of the ball 25 so that the ball, when seated, rests deeply therein to the end` that the lower bore portion 19e possesses a cross-sectional area which is just slightly less than one-half of the crosssectional area of the interior of thet'valve chamber or intermediate bore portion 19h, and so the cross-sectional area of the lower bore portion 19C very closely approximates the annular area between the ball 2S and the wall of the bore portion 1%.

To maintain the ball centrally within the chamber 19b, and thus limit lateral movement of the ball within the chamber, yet permit longitudinal movement therein, the illustrative device has four circumferentially-spaced, longitudinal ribs 23 rigid with the inner surface of the chamber 1911. The ribs project inwardly of the chamber 19h and while they are so sized that the ball 25 rolls freely between them, yet the clearance between the ball and the ribs is made as small as practicable. 1n this way the ball is permitted to roll freely away from its seat 26 when a bottle equipped with the instant device is inverted for pouring, and it can quickly return to the Seat 26 when the bottle is returned to an upright position.

To maintain the ball valving element 25 captive within the chamber 19h a stop 30 is provided. The stop 30 is preferably in the form of a fiat circular disc, of a diameter larger than that of the spout bore 21. It is transversely disposed in the upper end portion 19a of the body bore 19 substantially above the ledge 31 which marks the juncture of the intermediate portion 19h with the upper end portion 19a of the body bore. Preferably the stop disc 30 is mounted upon the lower or inner end of the spout 20 by a pair of diametrically disposed posts 32. These posts depend from the spout flange 24 into the outer end portion 19a of the body bore 19.

It will be observed that the foregoing construction not only places the stop disc 30 concentrically within the chamber 19a and in position to limit outward longitudinal movement of the ball 25, but it also defines a pair of wide, semi-cylindrical openings 34, between the posts 32 and between the disc 30 and the flange 24, for the passage of the liquid contents therethrough substantially unimpaired.

Means is provided to permanently retain the instant bottle closure in place upon the bottle neck once it has been installed therein. As shown, the body 16 is made of a length substantially longer than the length of the bottle throat 12. As indicated generally at 36, adjacent its lower end the outer surface of the body 16 of the instant device is tapered inwardly, and at its outer end it terminates in a peripheral flange 37. The flange 37 is, of course, of a diameter to pass through the throat 12. Between the tapered body portion 36 and the ilange 37, there is provided a circumferential groove 38 for the reception of a washer 39. Preferably the washer is normally at and generally circular but of split or C configuration. It is formed of a material which is relatively hard and tough, yet resilient in nature. Materials such as copper, brass, stainless steel, and certain forms of plastics such as nylon, Teflon and polyethylene may be used for this purpose.

As the instant bottle closure 1i), with the washer 39 in place thereon, is pushed into the constricted throat 12 of the neck 11 of the bottle, the circular split washer 39 is free to fold backward against the tapered outer surface 36 of the body 16. When the body has been pushed far enough so that the washer 39 passes beyond the internal neck shoulder into the bottle neck the washer returns to its normal ilat position as shown. Thus the device is permanently locked in place upon the bottleneck. Any attempt to withdraw the device from the bottle neck causes the washer to be urged against the ange 37 thereby resisting outward movement of the device with respect to the bottle neck. If an even greater outward force is applied in an attempt to withdraw the device, the washer 39 tends to fold back over the ange 37. This imparts a greater cross-sectional area to the lower or inner end of the device than that of the constricted throat 12, thereby positively preventing removal of the device from the bottle neck without either destroying the device or breaking the bottle.

Desirably, the body 16 is provided with a pair of passages 40 adjacent the inner end thereof to permit draining of any of the bottles contents that might be caught between the body 16 and the wall of the throat 12. As shown the passages 40 extend transversely through the body wall at the tapered portion 36 thereof and open into the lower portion 19e of the bore 19.

It will be observed that the construction and arrangement as illustrated and described not only facilitates pouring and effectively closes the bottle upon completion of a pouring operation, but in addition it precludes tampering with the closure so as to prevent relling. Thus it effectively insures against the introduction of adulterants, diluents, and unauthorized reuse of the bottle. The engagement of the ball 2S with its seat 26 prevents entry of liquid through the device into the bottle. Further the construction and arrangement is such that tampering to unseat the ball is precluded. The transverse disc 3i), which is of a larger diameter than that of the spout bore 21 prevents the straight insertion of any tampering device, such for example as a wire W as shown in solid lines in FIG. 6. If a wire or other similarly thin article was to be used, and it was manipulated through one of the openings 34 past the disc 30, its progress into the body bore 19 would be impeded by its engagement with the annular ledge 31. This is indicated as W by the dot-dash lines in FIG. 6.

But assuming a tampering wire was to be manipulated off the ledge 31, the tampering wire would necessarily curve inwardly. Thus it would engage the ball 25 as indicated by a wire W" in broken lines in FIG. 6. Because the ball 25 is of a diameter but slightly greater than that of the body bore portion 19C and thus rests deeply in its seat, and because of the provision of the longitudinal ribs 28, lateral movement of the ball from its seat is precluded. Even if a bottle equipped with the device were to be inverted so that the ball 25 would leave its seat, and if a wire or similar tampering article, such as indicated at W" in dotted lines, was to be manipulated between the ball and the bore wall 19b, its further movement into the bore 19C would be blocked by the annular ledge 26. Thus insertion of a wire through the device for the purpose of preventing reseating of the ball when the bottle is again brought into an upright position is precluded.

It is to be noted, too, that the length of the device, particularly that of the spout 20, contributes to its securiy ecause is length makes any manipulation of a tampering article substantially more ditiicult by limiting the articles effective lateral movement.

From the foregoing, therefore, it will be seen that a non-rellable closure and pouring device for bottles constructed in accordance with the teachings of the present invention facilities dispensing of the liquid contents of a bottle to which it is applied. It is operative to close the bottle when it is in an upright position, and it is not likely to fail in operation. As illustrated and described, the insertion of a tampering device to unseat or to hold the ball valving element off its seat is effectively precluded.

Further, thel device is of exceedingly simple construction consisting of but tive parts, namely, the body, the spout, the sealing gasket, the ball valving element, and the retaining washer. Each of these parts can be easily fashioned of plastic materials as by injection molding or casting in large numbers, and final assembly can be readily accomplished. Thus it will be appreciated that the device permits of exceedingly economical manufacture.
