This invention relates to a non-refillable bottle and more particularly concerns a bottle embodying novel valve mechanism adapted to permit free discharge of liquid from the bottle but which will effectively discourage attempts to refill the same.

Bottles in which liquids of known characteristics and quality such as fine beverages are dispensed are oftentimes refilled by unscrupulous persons with an inferior liquid and the imitation disposed of as the genuine product. This fraudulent practice is of damaging consequences to the original producer because the user will not be aware of the deception due to the genuine bottle in which the imitation is sold to him, and will thus unjustly attribute the inferiority of the imitation to the original. Attempts have been made in the past to provide means for preventing refilling of bottles but these have met with indifferent success, usually as a result of impracticability due to the unusual shapes of bottles, complicated and expensive structure, the ease with which the sealing parts could be penetrated or removed and replaced without leaving a detectible trace, the ease with which the operation of the valves could be disrupted through the medium of skillfully operated instruments, or similar undesirable characteristics.

The principal object of this invention is to provide a practical non-refillable bottle including a small, freely operating, permanently secured valve unit which embodies a simple, eflicient and compact arrangement of standardized parts capable of being easily and quickly assembled into a structure which can be manufactured, sold and installed at a low cost.

Another object is to provide a non-refillable bottle of the foregoing character including a unitary valve device embodying a plurality of coacting return flow preventing means one of which has means associated therewith for the purpose of normally keeping it closed against the return flow of liquid through the device.

Another object resides in the provision of a non-refillable bottle including a valve unit embodying a reciprocable valve having resilient means for urging it into closed position and adapted to allow the valve to open. fully only when opposed by the force of a predetermined quantity of liquid after the bottle is tilted for pourmg.

Another object is to provide a non-refillable bottle embodying a valve unit having inner and outer valves affording a fluid discharge passage of fixed dimensions providing an undiminished effective flow area through the unit but operative to prevent the return of any substantial quantity of liquid to the bottle, the outer valve being gravity operated and the inner valve being reciprocably mounted and adapted to be urged to open or sealing positions by the aid of entrapped liquid.

A further object resides in the provision'in a device of this character of a valve which is normally seated and has flow directing means associated therewith for effecting an impression on said valve of the force of a predetermined quan- "ty of fluid when pouring whereby the valve is forced open, and for subjecting the valve to the force of incoming fluid when an attempt is made in any manner to introduce fluid into the container, whereby to insure an immediate and positive return of the valve to its normal position.

More specifically stated, another object is to provide a valve which embodies fluid entrapping cups or the like oppositely arranged to face inwardly and outwardly of the container, and which has associated therewith means for normally urging the valve into its seated position, and flow directing means disposed so that the initial flow past said valve in either direction is into one or the other of said cups to open the valve against the force of the valve urging means during a pouring flow and to effect an instant closing of the valve during a reverse or incoming flow.

Another object resides in the provision of nonrefillable valve mechanism of the foregoing character including a pair of coacting valve units each separately fashioned from a plurality of snugly interfitting metal parts designed for simplicity and ease of assembly, these units being operatively enclosed permanently within containing means, thereby forming a complete mechanical unit adapted by a simple operation to be united permanently with a bottle after the latter has been filled.

Another object is to provide in a valve mechanism of the foregoing character a structure embodying a gravity acting valve having a contact face of substantial area enclosed within limiting means of substantial area including means to prevent possible adherence of the valve thereto in open position when functioning normally, and designed to be relatively weak so as to be physically distorted into a position to bind said valve member closed upon the application of any force should tampering be attempted by means of an instrument inserted through the discharge opening.

Other objects and advantages will become apparent in the following description and from the accompanying drawing, in which:

While the invention is susceptible of various modifications and alternative constructions, I have shown in the drawing and will herein describe in detail, the preferred embodiment, but it is to be understood that I do not thereby intend to limit the invention to the specific form disclosed, but intend to cover all modifications and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims.

The term non-refillable bottle as used herein to designate the invention is not intended to mean a structure that is entirely proof against refilling. Ingenious ways and means may be known or found by the unscrupulous for overcoming the safeguards provided by the invention, but the device is of such a nature as to prevent direct refilling, and to render commercially impractical .expedients that may be adapted for the purpose of returning liquid to the bottle past the valve mechanism. This result is attained primarily by preventing the return of any substantial quantity of liquid to the bottle within a time period of considerable duration.

The features of the present invention are embodied in a simple unitary structure capable of being permanently affixed to the neck of a bottle or similar container. To prevent refilling, the structure includes a pair of cooperating valves successively interposed in the path of flow. One valve is gravity acting and by its design has a closedposition except when pouring liquid or when the bottle is tipped below a horizontal position. The other valve is urged by a spring or other suitable means to be closed in all positions of the bottle except when fluid is actually passing from the bottle. Moreover, this valve is preferably so constructed and related to its urging means as to utilize the force of a predetermined quantity of fluid in opening the valve, thereby positively preventing the valve from opening once the bottle is empty, yet producing a valve which under normal conditions opens freely.

With reference to the drawing, the invention is embodied in a practical form in a valve unit generally designated I in association with a conventional glass bottle ll having an annular neck l2 of a simple design.

Within the neck I2 is a snugly fitting, uniform- 1y dimensioned, cup-like cylinder l3 having a laterally extending flange l4 resting over the outer end of the neck, a suitable gasket [5 of liquid proof material being interposed between the fiange and neck to form a liquid tight joint. Closure means herein shown as a dome ll converges arcuately outwardly from the flange periphery and toward the bottle neck axis in a pleasing contour to provide a substantial chamber l8, and thereby to complete an enclosure for the internal mechanism of the valve unit. Near the center, the wall of the dome opens outwardly to form a pouring spout l9 which provides a discharge opening communicating with the interior of the bottle. Means such as mutilated screw threads 20 is formed in the pouring spout for securing a screw cap 22 thereover.

Means for connecting the dome in place is herein shown as consisting of a retaining skirt 23 adapted to embrace the adjacent parts of the dome and bottle neck. This skirt 23 herein is preferably a metallic shell which converges inwardly at its outer end and follows the contour of the dome in snug engagement therewith. At itsopposite end the skirt 23 extends substantially beyond the inner edge of the dome about the neck l2 and has its end pressed as by a spinning operation into an annular bead 24 which is snugly received in an annular channel or groove 25 in the bottle neck. In order to prevent removal of the skirt, the groove 25 is fashioned to provide a right angular shoulder forming an impassable impediment to any attempt at forcing the skirt from place. Beyond the shoulder, the groove assumes an arcuate contour and the end of the skirt follows this contour, gradually thinning to a feather edge, and remaining entirely within the curvilinear plane of the bottle neck. Insertion of a tool under the bead in an at.- tempt to spread the same is thus rendered exceedingly difiicult and even if successful must result in destruction of the skirt. During the operation of pressing the bead into the groove 25, the skirt 23 is drawn tightly against the dome to force the same solidly against the end of the bottle neck. Preferably the dome wall is offset inwardly between its base and the port defined by the pouring spout is, as at 21, equal to the thickness of the skirt so as to bring the outer surface of the skirt flush with the exposed dome surface. The outer edge .of the skirt 23 preferably engages the shoulder in the dome provided by the offset 21, thereby blending into a smooth contour to provide a pleasing outward appearance.

Within the shell or container provided by the cylinder E3 and the dome ll, is a plurality of cooperating sealing valves, herein shown as two in number, which are adapted to permit the ready discharge of liquid from the bottle but are cooperative to restrict the reentry of. liquid. One of these valves, indicated generally by the numeral 28 and hereinafter termed the inner valve, is a cylindrically shaped device operating with a reciprocatory piston-like movement. Its preferred construction comprises a cup-like sleeve 29 dimensioned for nugly fitting within the cylinder l3 and having a base 30. To facilitate free reciprocal movement of the sleeve 29, spaced longitudinal bearings 3| may be formed on the wall of the cylinder 13, these bearings actually protruding only very slightly from the wall, but appearing exaggerated in Fig. 5 for purposes of illustration.

Supported in concentric fashion by the sleeve 29 is an inwardly facing cup 32 forming the valve proper. Preferably, this cup is of a diameter substantially less than that of the sleeve, and means is provided for securing the sleeve and cup in uniform laterally spaced relation. To this end a spacer, comprising a pair of concentric rings 33 and 34 connected by spaced legs 35, and preferably developed from a single piece of stock metal, is seated within the mouth of the sleeve 29. The inner ring 34 fits snugly about the base of the cup, and for convenience in assembly, the cup base is offset as at 36 to provide a locating shoulder 37 against which the ring 34 abuts. A rabbeted groove 38 is preferably formed adjacent the mouth of the sleeve 29 for snugly receiving and locating the outer spacer ring 33.

The offset cup base portion 36 is formed to extend substantially beyond the ring 34 in order to provide connection for a band or sleeve 39 adapted snugly to fit thereabout. The sleeve extends beyond the base of the cup whereby in effect to provide an outwardly facing cup similar to the cup 32, the base of both cups being common.

An inturned flange 49 at the inner end of the cylinder 13 furnishes a seat for the valve cup 32 which is adapted to form a liquid seal over the opening defined by the flange. Thus, in the non-pouring positions of the bottle the valve cup will prevent a return flow of liquid. In order to insure a thorough sealing relationship, the rim of. the cup 32 is slightly flared and finished to develop a lip 42 adapted snugly to coact with a complementary protruding lip 43 formed at the inner edge of the flange 40. It will be observed that while the valve cup 32 provides an effective obstacle to the return flow of liquid, it is so arranged that outflowing liquid will first enter the same before passing on toward the discharge spout l9. In this the seat lip 43 serves a funnel-like purpose. Discharging liquid thus acts upon the inner valve in a direction which forces it into open position.

When open, the inner valve unit 28 affords a uniform discharge passage of substantial flow area. This is accomplished by the lateral spacing between the parallel cup, cylinder and sleeve walls and by reserving a substantially spaced relation between the sleeve and base 39 and the outer edge of the cup sleeve 39. Flow of liquid from the interior of the inner valve unit is through a centrally formed aperture 44 in the base 39, this aperture being coaxial with and of a diameter preferably slightly less than that of the sleeve 39. Thus, a return flow of liquid will be directed through the aperture 44 first into the outwardly facing cup whereby to impress a force against the cup base tending to move the valve unit back into sealing position. Desirably the cup sleeve edge may be slightly flared as at 45 to facilitate reception of the return-flow liquid. A quantity of this liquid may" be entrapped within the outwardly facing cup and by its weight bearing upon the cup 32 will serve to improve the liquid-tight relationship of the sealing lips 42 and 43.

Between the inner valve 29 and the pouring spout I9, is a second valve 45, hereinafter designated the outer valve. The latter is preferably fashioned as a slightly arcuate disk to provide an eccentric weight distribution and is disposed with its convex face toward the inner valve. Means providing a seat for the valve 46 and arranged to define within given limits its path of movement away from the seat surrounds the outer valve and is supported upon the cylinder flange [4. In the present instance this means comprises a housing 41 shown as including a rim 48 and a disk 49 connected in spaced parallel relation by a plurality of thin substantially spaced legs 59. The rim 43 is provided with an annular oifset 52 adjacent its innor periphery adapted to receive snugly a thin, fiat axially apertured retaining disk appearing as a ring or washer 53 which provides a seat for the valve 46. As will be seen in Fig. 2, the outer edge of the rim 4B is turned up slightly as at 54 to form an annular bearing adapted for engagement with the wall of the dome ll. In order to facilitate assembly, the oifset portion 21 of the dome may be fashioned to provide a shoulder 55 defining the assembled position of. the rim within the dome. At its edge, the dome wall may be turned over as by a spinning operation to form a clamping flange 51 for permanently securing the cylinder flange l4 tightly against the inner face of the valve seat ring 53, thereby forcing the housing rim bearing 54 into firm engagement with the shoulder 55 and joining the assembly into a complete unit.

In diameter the outer valve is preferably such as to maintain only a slight clearance between its edge and the housing legs 50; so that as the bottle is tilted for pouring, the valve disk will shift only slightly on its seat. This slight shifting, however, is sufficient to carry the lower edge of the valve disk forwardly to an extent which together with the eccentric inward disposition of the weight center of the disk mass will cause the valve to retain its seat until the bottle has been tilted to carry the discharge end below a horizontal plane, whereupon the valve will come to rest against the outer housing disk 49. In order to prevent possible adhesion of the outer valve disk against the housing disk, inwardly pressed spacer grooves 58 are formed in the disk 49.

Moreover, the housing 4'! may be fashioned as one piece through the medium of a spinning operation, and the disk 49 and the legs 50 will thus be relatively thin and fragile so that if it is attempted to drill through the housing disk 49, the legs will collapse upon the application of any amount of pressure, thereby causing the housing to collapse and to lock the valve 46 in place. In the event that a drill should be passed through the disk 49 into engagement with the outer valve disk, the latter will simply rotate under the force of the drill, the contacting faces being smooth and there being no projections to prevent such rotary movement. Furthermore, the housing disk and supporting legs are designed to be physically deranged to prevent opening of the outer valve upon the application of force by tampering instruments of any other nature inserted through the discharge spout. Thus, attempts to by-pass the outer valve by instrumental means in order to return liquid to the bottle will be effectually prevented.

In the present instance, the inner valve 28 is suitably loaded by means adapted to insure a normally sealed relationship of the valve except when pouring liquid from the bottle. To this end the valve is loaded by a spring 69 which is interposed between the sleeve base 30 and the inner face of the retaining ring disk 53. This spring may be formed as a ring seating on the sleeve base and having a plurality of resilient helical fingers 62 bearing against the ring disk 53. In tension the spring is such that the weight of the inner valve 28 is of itself insufiicient to compress the spring; and regardless of the position of the bottle, the valve will be maintained seated except when a predetermined quantity of liquid, generally indicated in Fig. 4 by the numera165, has been trapped in the cup 32. The weight of this liquid together with the weight of the cup will be sufficient to overcome the tension of :the spring, compress the same and unseat the valve.

From a practical standpoint, the valve mechanism of this invention lends itself peculiarly well to mass production methods of manufacture. Each component part may be fashioned accurately in quantity according to a standard pattern from metal stock, as by stamping, spinning, or other suitable commercial process. Assembly of the parts into complete compact units ready for afiixing to filled bottles may be accomplished with great rapidity and a minimum of operations on an assembly line. Thus, referring to Fig. 3, in assembling the inner valve structure the cup base 36 is fitted into the spacer ring 34, the sleeve 39 slipped over the projecting cup base, and the outer spacer ring then fitted into the rabbeted groove 38 in the reciprocatory sleeve. The assembled inner valve 28 is then dropped into the cylinder l3, and the spring placed on the sleeve base 30. By a simply and speedily executed action the outer valve 46 is placed within the cage housing 41, the disk ring 53 secured in the groove 52 and the housing fitted into the grooved wall of the dome ll. Finally, the dome is placed over the cylinder fiange M, the clamping flange 5! turned in to secure the parts together, and the gasket l5 slipped into place. Thereafter, all that the bottler need do to complete the bottle assembly is to associate the unit with a filled bottle, place the retaining skirt 23 and spin the bead 24.

In pouring liquid from the bottle, it will be tilted until the outer valve 46 is overbalanced and leaves its seat. Simultaneously, the predetermined quantity of liquid will enter the cup 32 until the combined weight of valve and liquid overcomes the tension of the loading spring 60, whereupon the inner valve slides to the open position as shown in Fig. 4. A flow path of undiminished efiective flow area thus is opened through the valve assembly, the liquid passing through the aperture defined by the seat 43 past the cup 32, between the rings 33 and 34 of the spacer, between the walls of the sleeve 29 and the sleeve 39, through the concentrically arranged aperture 44 and disk ring 53, and past the outer valve 46 through the housing 41 into the chamber Hi from which the liquid will issue through the pouring spout I9.

As soon as the bottle is returned to a horizontal position, the outer valve 46 will resume its seat, and the liquid 65 will escape from the cup 32 so that the spring 60 will again become effective to force the inner valve into sealing relationship with the seat 43. Movement of the bottle towards the non-pouring position also causes any returning liquid to be directed through the base aperture 44 into the outwardly facing inner valve cup, further aiding in seating the inner valve.

Insertion. of an instrument toward the interior of the valve unit for disrupting the proper seating of the valves is prevented by the arrangement of the housing disk 49 relative to the discharge opening afiorded by the spout l9. Furthermore, the housing structure 41 is such as to prevent attempts at tampering with instruments. Due to the cooperative relationship of the valves, and the spring loaded characteristics of the inner valve in particular, any attempt to return liquid in quantity by submergence of the bottle will be prevented. Moreover, by reason of the outwardly facing inner valve cup into which an inflowing stream is directed, attempts to refill the bottle by vacuum or force are frustrated.

It will thus be evident that the invention provides a small, neat, non-refillable valve structure of few and simple parts efficiently and compactly arranged for economical manufacture and assembly; adapted to be formed as a self-contained unit which may be quickly and permanently secured to the bottle; and embodying a plurality of coacting valves one of which is not only loaded to normally maintain the same sealed, except when pouring, but is also adapted to receive functional aid from the liquid passing through the mechanism. Manifestly, once the liquid is exhausted from the bottle, the loaded valve will effectively prevent attempts at refilling.
