Application October 7, 1941, Serial No. 413,940

Claims. (Cl. 215-22) This invention relates to bottle closures of the type designed to discourage fraudulent refilling of bottles for profit.

An object of the invention is to provide an assembled closure unit primarily for use on whiskey bottle tops of standard diameters, and particularly those in common use having external threads for the application of ordinary screw caps, but in this instance such bottles having in addition a novel configuration of the walls of the bore through the neck effective, as a contributing factor, to prevent the removal of the closure from the bottle unless destroyed or otherwise visibly mutilated.

Another object of the invention resides in the provision of simplified valve parts within the closure, yet 'sufiiciently effective for the purpose set forth without exceeding in cost the price range held to be commercially feasible by thetrade.

A further object of the invention is to provide a bottle closure of this character that can be applied by the bottler with the same general type of machinery at present employed to apply screw caps, thus avoiding the necessity and added expense of special machinery, and also the difficulty arising from any disturbance of existing transportation facilities through the bottling plant.

Yet another object of the invention is to provide a special bottle finish suitable for locking this closure to the glass, that is practical to manufacture and without added expense. Further objects of the invention are hereinafter set forth.

Heretofore it has been the common practice to apply bottle closures of this type by t e use of a metal ferrule which is spun over suitable beads on the glass finish with special machines. This involves an added expense for the ferrule together with the potentiality of its removal and fraudulent substitution. Another serious objection of the bottling industry to this practice is that a double inventory of bottles is requ red, as bottles with finishes for spun-on ferrules are not suitable for use with either corks or screw caps. The bottle finish of this invention however possesses the advantage of equal adaptability to standard screw caps, and without interference with the special locking feature of the finish hereinafter to be described.

The closure of the invention consists of a twopiece housing for enclosing the valve parts, the outer member of which is rotatable, and the inner member of which is locked to the glass finish so as not to be rotatable. A circular row of ratchet teeth formed on the respective housing members in opposed relation, coact to provide for the rotation of the outer member when screwed onto the'threads of the bottle finish, but to prevent counter rotation thereof, since the inner member is held in a fixed-position by the special configuration of the Walls of the bore through the top finish of the bottle.

The invention further consists of certain buoyant valve parts constructed to nest together compactly, and with provision for the release of adventitious vacuums to facilitate the pouring of the contents of the bottle to which the closure is applied. i

The invention will be more fully understood by reference to the drawings forming a part of this specification, and. in which,

Fig. 1 is a vertical section of the closure of this invention showing the same'attached to a bottle top having the special finish referred to.

Fig. 2 is a bottom plan view of the outer mem ber of the housing of the closure.

Fig. 3 is a top plan view of the inner member thereof.

Fig. 4 is a bottom plan view of the same.

Fig. 5 is a side elevation thereof.

Fig. 6 is a horizontal section taken on the line 6-6 of Fig. 1.

Fig. 7 is an elevation, partly in section, showing the top of a bottle neck with a finish in accordance with this invention.

Fig. 8 is a sectional detail view of the lower portion of the outer housing member of the closure shown in Fig. 1, and,

Fig. 9 is a fragmentary top plan view of a modified form of bottle finish, and showing in section a conforming outer configuration of the inner member of the closure.

Referring now in detail to the drawings, the top of a bottle neck is indicated at IB,.having a finish above the usual annular bead or flange H consisting of the conventional threads l2 externally formed thereon. The bore 13 however is of particular configuration to provide one or more interruptions in the continuity of the usual circular character thereof. In this instance such interruption-s consist of a plurality of surfaces 54, generally similar to the side faces of an octagonal nut, which are easily formed inthe glass when the bottle is blown by first simply facing oh the pin commonly used-with the neck rings of the bottle mold, and which rings form the desired outside finish for cork-s or screw caps as the case may be. This configuration may be molded in the glass in a practical manner, as in usual practice the neck rings are hinged together, and when opened to free the bottle, it falls away, and the pin carried by the neck ring is therefore withdrawn along a plane axially aligned with the bottle. Preferably the surfaces M are comparatively shallow and only extend a short distances into the bore of the bottle from the upper extremity of t e finish.

The closure assembly is made up of an inner housing member I5 having a valve seat 56 and an inlet opening therethrough IT, a gasket I8, an outer housing member l9, and valve mechanism comprising a duplex valve consisting of two members 20 and 2|, hereinafter referred to as the primary and secondary element respectively", and a tumbler weight member 22'. These parts are held in assembly with the bottle neck in a manner to be presently described.

With the exception of the weight 22, preferably made or porcelain, and the cork gasket It, the above parts may be made of certain types of plastics. Several varieties of these materials are now known to be sufficiently resistant to aic'oiioue liquors for which this closure is partlciilarly adaptable, and may be manufactured in multiple cavity molds for large quantity production both by compression and injection molding methods.

The outer member If! may be made of one of the cheap-er plastics, such as'Bakelite. Member together with the Valve elements 28 and El, may be made of more expensive but highly resis'tairt' thermo-plastie material, such as polystyrene, by injection molding technique. These thefino 'plastic' parts are relatively small and therefore comparatively cheap to manufacture from this material.

The inner member l5 is provided with an annular flange l5 which, as shown in Fig. 1, overlies the gasket I8 which intu'rn rests upon the top or the bottle neck i0. Il'ie top surface of the flange i5 is provided with an upwardly projecting plurality of ratchet teeth l5" in the form of an annulus, as shown in Fig. 3, and facing toward the left, as shown in Fig. 5. Member 19 is provided with an annular shoulder IS on the under surface of which is formed a downwardly extending plurality of ratchet teeth is", but each tooth facing in a direction opposite to that of the respective teeth I5". The number of teeth so formed on each of the members is a matter of choice, thirty-six being indicated as a suitable number fer use in this example of the invention, and the purpose of whichwill presently appear. Member I ll is also provided with another annular shoulder 23 arranged to contact with the gasket l8 to prevent leakage from the interior of the valve housing to the exterior of the bottle neck, any internal leakage. which might otherwise bypass the Valve elements. being prevented by a similar engagement of the flange l5 with the ass is.

Member H! has a depending skirt portion 24 which is internally threaded at 25 for engagement with thestandard threads I: formed on the ext-eriogpr the bottle neck above the bead or flange H. This part of the bottle neck including the bead II, together with the bore through the top 61? the neck, is known as the bottle finish to those skilled in the art or tome making.

Member I5 is provided with a plurality of surfaces is on its exterior immediately beneath fla ge [5, resembling those on a nut or bolt head, and which are complementary to the sur- 4 faces M of the bore of the bottle neck, and with which they cooperate to prevent rotation of element I 5 within the bottle neck, except to a minor extent.

Beneath surfaces 28 the remaining portion 23' of member I5 is cylindrical and slightly less in diameter than the bore of the bottle neck below the surfaces l4, and also less than the diameter across the point of intersection of the surfaces 28 indicated by the line A-A of Fig. 4.

It will now be apparent that when members 5 and I9 of the valve housing are assembled togetner in the position shown in Fig. 1, with the gasket i8 pressed tightly in place, that these parts will provide a unitary bottle closure ready for application to a bottle. Also that the internallly threaded skirt 24 of member is may engage the external threads 12 following the introduction of the cylindrical portion 28' of member I5 into the bore of the bottle neck, and that as member [8 is rotated clockwise about threads ii with member [5 held stationary by the coacting surfaces l4 and 28, the ratchet teeth 15" and i9 will jump one over the other by reason of the sliding engagement of their sloping surfaces, while at the same time pressure will be built up on the gasket it between the top of the bottle and the shoulder 23 and flange l5, until a tight seal has been established with the teeth meshing. Because of the yieldable character of the gasket its resiliency, the ratchet teeth on the one element are enabled to jump over those on the other element until substantially the maximum degree of compression of the gasket has been reached. The resiliency of the gasket, active against flange i5, is effective to keep the two groups of ratchet teeth in looking engagement with the upper set bottoming in the lower ones.

Now if an attempt is made to unscrew member l9, the same will be prevented by the engagvertical faces of the teeth, the resulting twisting components being transmitted to member l5. But since the diameter across line AA is greater than across line and which is also true of the configuration defined by the surfaces 14, the points across line A--A of member 15 will im inediately engage said surfaces [4 because of the diminished diameter of the latter on line B-B, and member is cannot therefore be rotated in a counterclockwise direction to remove same, and in consequence thereof the valve housing unit cannot be removed from the bottle without breakage occurring.

The valve parts within the housing may be of any desired character commercially effective to preventrefilling of the bottle through the clo sure Without removal of the latter, but those shown and described herein are adaptable to bottle closures of restricted diameters, to fit within whiskey bottles of standard sizes, and without loss of the pouring capacity demanded. They nest together compactly in order to keep within reasonable limits as to closure depth, thereby cheapening and at the same time avoiding undesirably long extensions within the bottle neck, or ungainly lengths above the same, or both. The material from which the valve parts are inade possesses a low specific gravity rating (1.5 to 1.73, and is therefore light enough in weight to be very sensitive to the influence of liquids when moving in a direction toward said valve seat. Furthermore both of the valve elements are made hollow, not only for compactin assembly, but so as to float in a boat-like manner when the bottle is in an inverted position and liquid is introduced. The tumbler weight functions to hold the primary and secondary valve elements in seated relation to each other and to the seat l6 of member l when the bottle is upright, and to also quickly move the elements from an open to a closed position when the'bottleis on its side.

Should climatic vacuums develop within the bottle due to atmospheric temperature changes, it can still be poured despite the tight seating of the parts, because such vacuums can be readily broken when the bottle is inverted, as the secondary element may then fall away from the primary element and momentarily uncover a relatively small air-vent opening 2! through the primary element. This is because such vacuums are negligible in extent over such a small area. As soon as air pressures thus become equalized at opposite ends of the primary element, the latter will also fall away from the seat is under the influence of gravity, or the hydrostatic pressure of the contents of the bottle, and the resulting flow will be continuous until the bottle is emptied.

The areas of the pouring passageways from the valve seat toward the final opening 26 at the top of member l9, should be of a progressively increasing nature to ensure continuous pouring without back pressure tending to reseat the valve elements, and particularly the passageway above and about the weight 22 should be ample.

The configuration of the face of the primary element and the seat I 6 is such as to provide a line contact with each other to effect a tight joint. Also the top of the primary element and the contiguous wall 23" of the secondary element 20, are likewise of a particular configuration for a similar purpose, and in both instances to minimize any adhesion therebetween tending to impede their desired movements when wet. Ribs 23 extend radially outward from the cylindrical wall of the secondary element 20, to provide passageways for the egress of liquid, and are also effectiveto guide this element during its move-' ment within the member l5. Lugs. 22 on the tumbler 22 provide pouring passageways for the liquid contents of the bottle, both between the tumbler and the side as well as the top walls of member I9.

Member I9 may be provided with external threads 29 for the application of the usual 28 mm. metal cap shown at 30, which is adapted to seat on the annular rim of the outlet opening 26. However the upper end of member 18 may be smooth, and a disk of wood or other material, with cork attached thereto, may be employed as a terminal seal instead of a screw cap. In either instance a suitable contour will be provided to facilitate the application of the revenue stamp commonly used on bottles containing alcoholic beverages.

Referring again to the valve elements, additional means are provided for guiding and aligning them in respect to their relative movement, and to their movement jointly within member l5 respecting valve seat l6. For such purposes ribs 29 are effective in the first instance, and in the second instance lugs 2|" projecting radially from the annular walls of the primary element adjacent the segmental spherical lower end thereof constituting a valve face, serve to support and guide, and align this element with seat l6, particularly when the bottle is in a horizontal position.
