Description

April 24, 1962 A. WHITTAM NON-REFILLABLE BOTTLE CLOSURE Filed March 1, 1961 In venlor 445E er WV/ZVWM By A llorn e y nited States at This invention is concerned with the provision ofan improved and still more eflicient construction of nonrefillable bottle closure than those heretofore available.

It is usual to apply non-refillable bottle closures to bottles containing whisky and other spirituous liquids at an average room temperature in the region of 60 Fahrenheit (15.5 degrees centigrade), but as the bottles in the course of transit or storage may be subjected to temperatures of 45 F. (7 C.) or even less, a vacuum may be formed between theliquid and the bottle stopper. This frequently causes the movable parts of the non-refillable bottle closure to adhere firmly together so that difficulty is experienced when it is desired to commence pouring out the liquid. Before pouring can commence, it is necessary to be able to break the vacuum by first admitting air into the bottle through the bottle stopper. It is one of the primary objects of the present invention-to provide a bottle closure which will not only ensure against fraudulent refilling of the bottles and against contamination of the liquid by contact with cork, rubber or other substances which would affect the flavour, taste or aroma of the liquid, but also to provide a bottle closure which will permit the contents of the bottle to be poured even when a vacuum has been created in the bottle by the different temperatures to which the bottle and its contents have been subjected during transit and storage. This is of paramount importance where whisky and like spirituous beverages have to be shipped from temperature zones to hotter or colder climates.

A non-refillable bottle closure according to the present invention comprises a cup-shaped valve member having a bottom wall closing a main outlet aperture in the inner end of a valve casing inserted in the bottle neck, said bottom wall having a small central air inlet aperture, which is preferably countersunk to provide a seat for a small spherical valve, which may be a small glass ball, the said valve or ball being movably contained in the cup-shaped valve member so as to close said air inlet aperture, and a superposed weight, of substantially larger diameter than the small spherical glass ball or valve, is movably contained in the said valve casing and normally rests on and loads the small spherical glass ball or valve and also loads the cup-shaped valve member in the closed position. The weight is preferably spherical and also made of glass and may have a diameter equal to at least twice the diameter of the small spherical ball or valve.

According to a further feature of the invention, the weight or larger glass ball is movably contained between the prongs of a pronged member which is located in the upper end of the valve casing and is held in position by a nozzle member which forms a pouring spout, having an axial passage communicating through lateral openings in the upper part of the pronged member with the space around the weight or larger glass ball.

The pronged member may comprise a solid disc from the periphery of which the prongs project downwards in the valve casing, the disc being supported from a supporting flange by a tubular portion between the disc and flange and lateral openings being provided in the tubular portion to connect the interior of the valve casing with a central aperture in the said supporting flange, said aperture being coaxial with the axial passage through the nozzle member. A shouldered portion of the nozzle member holds the flange in position on the rim of the bottle neck against a flange on the outer end of the valve casing, the nozzle member being secured in position in known manner by a thin sheet metal seal pressed around the shouldered portion of the nozzle member and around the bottle neck.

With the exception of the small spherical valve and the larger spherical weight, which are preferably made of glass, all the parts are preferably made of a transparent or translucent synthetic resin which is non-injurious to the flavour, taste and aroma of the spirituous beverage in the bottle.

Other features of the improved bottle closure are hereinafter described with reference to the accompanying drawings showing the preferred construction.

In the drawings:

FIG. 1 is a vertical sectional view through the bottle neck and closure device.

FIG. 2 is a side elevation of the pronged member.

FIG. 3 is a vertical sectional view of the cup-shaped valve member.

The drawing shows the neck 1 of a bottle which is internally formed with a cylindrical surface 2 to receive the outer cylindrical surface of a hollow cylindrically formed valve casing 3, which is a close fit in the bottle neck 1. The casing 3 has an upper external flange 4 which rests on a sealing ring 5 on the rim of the bottle mouth. The sealing ring 5 is preferably made of cork. The casing 3 is formed with an inwardly tapered wall 6 which is integral with a cylindrical extension 7 which projects into a narrower portion 8 of the bottle neck. The extension 7 forms a lower valve chamber and has a transverse bottom wall 9 with an upwardly turned inner lip 10 around a central opening 11. The lip Ill forms a valve seat for a movable cup-shaped valve member 12 (shown separately in FIG. 3) which has a flat bottom wall 13 in the centre of which is a small countersunk valve aperture 14. A small spherical glass ball valve 15 contained in the cup-shaped member 12 is adapted to seat in the countersunk end of the valve aperture 14. The inner cylindrical part of the cup-shaped member 12 is formed with a plurality of spaced inwardly projecting vertical ribs 16 whih act as guides for the small ball valve 15.

The tapered wall 6 of the valve casing 3 also has spaced inwardly projecting ribs 17 which are continued vertically downwards at 18 along the inside of the extension 7. The ribs 18 serve as spaced guides for the vertical outside wall of the cup-shaped member 12. A larger glass ball or weight 19 rests on the smaller ball valve 15 and on the ribs 17. When the bottle is tilted, the ball or weight 19 is received between prongs 20 projecting downwards from a pronged member which is shown separately in FIG. 2. This member comprises a flange 21 having a thickened part which forms a circular ridge or shoulder 22.and a tubular part 23 which has diametrically opposite lateral openings or slots 24- formed through it. The tubular part 23 ends below in a solid disc 25 from which the prongs 20 project, so that the ball or weight 19 is free to move between the lower ends of the prongs. A central opening 21a extends through the flange 21 and its thickened part 22. The flange 21 rests on the flange 4 of the valve casing 3 with the thickened part 22 engaging in the top of the valve casing 3.

A nozzle member 26 has a central axial passage 27 which registers with the opening 21a in the flange 21, so that the nozzle member forms a pouring spent for decanting the liquid from the bottle. The nozzle member 26 has a shouldered flange '28 which embraces both the flange 21 and the flange 4 which rests on the sealing ring 5.

When the parts are assembled as shown in FIG. 1, the bottle closure thereby formed is secured to the bottle neck in known manner by pressing a thin sheet metal shell 29 around the flange 28 and bottle neck so that the nozzle member 26 cannot be removed without breaking the seal formed by the thin metal shell 29.

The nozzle member 26 is screw-threaded at its outer end at 30 to receive a screw-cap for sealing the bottle contents.

The solid disc 25 of the pronged member is preferably formed with a convex upper surface 31 to deflect a wire or other tool if inserted through the pouring spout with any fraudulent intention.

The spaced ribs 16 form channels between them through which air or the liquid contents of the bottle can flow when the small ball valve 15 moves away from the aperture 14. Similarly, the spaced ribs 18 form channels between them through which air or the liquid contents of the bottle can flow when the bottom wall 13 of the cupshaped valve member 12 is free to move away from the lip 10 of the aperture 11, which can take place only when the small ball valve 15 is released from the pressure of the weight 19 by tilting the bottle.

The bottle is normally filled and stoppered at a temperature of about 60 F. (15.5 C.). When it is desired to decant the contents and a vacuum has formed, it is first necessary to tilt the bottle so that the weight 19 falls away from the small ball valve 15. Air then enters through passage 27 and slots 24 into the space between the prongs 20 around the weight 19 and passes around the small ball valve 15, the air entering the bottle through the small valve orifice 14. As soon as the vacuum is broken, the air pressure balance allows the base 13 of the cupshaped member 12 to lift away from the lip 10 so that, when the bottle is again tilted, the liquid pressure lifts the cup-shaped member 12 and allows the liquid to flow out through the aperture 11 into the spaces between the ribs 18 and into the space between the prongs 20 and from thence out through the slots 24 and outlet passage 27.

The whole of the parts, with the exception of the cork ring and glass balls 15 and 19, may be made of artificial resin, such as polythene, polystyrene or other resinous product which will not have any adverse effect on the flavour, taste or aroma of the liquid.
