FLUID DISPENSING DEVICES United States Patent O -The present invention relates to the field of iluiddispensing devices, and more particularly to a combined stopper and iluid discharge unit that may be removably mounted in the mouth of a bottle.

`The primary purpose in devising the present invention is to provide means by which alcoholic beverages in bottles are sealed from contact with the atmosphere at all times, except when the beverage is being dispensed.

In bars, cafes, and other establishments of this type, it is common practice to have numerous opened bottles of liquor displayed. The liquor so displaced is normally of high alcoholic content, and is dispensed from the par ticular bottle for which the customer calls through a normally open spout that extends downwardly through a stopper.

Dispensing of liquor from bottles in the .above described manner has several objectionable features. One of these features is that alcohol is quite volatile, and over a period of time a considerable amount of liquor in a bottle may be los-t due to evaporation that takes place through the pouring spout of the bottle. Another objectionable feature inherent to the normally open pouring spout is that it permits the alcohol in the liquor to absorb moisture from the atmosphere.

it will readily be apparent that the proof `of liquor in a bottle having an open spout may change drastically over a period o-f time due to evaporation of alcohol and the absorption of water by the alcohol remaining in the bottle. Both the State and Federal Government have roving `inspect-ors that may unexpectedly drop in and check the alcoholic content of liquors being dispensed by a bar, with the proof .as printed on the labels of the bottles. Failure of the contents of a bottle of liquor to agree with the proof printed on the label thereof indicates adulteration of the liquor, and has been the reason for numerous bars being closed or having their licenses suspended. The fact that the adulteration or dilution of the liquor in a bottle occurred innocently due to the reasons above dey scribed is diicult to prove, and will not normally excuse a discrepancy between the actual alcoholic content in the liquor in a bottle and that printed on the label alixed to the bottle.

ln an effort to remedy the above mentioned situation .a variety of devices have been proposed that may be mounted on the mouth portion of a bottle to seal the contents of lthe bottle from contact with the atmosphere. However, the majority of these prior art devices were of cumbersome appearance, complicated in structure, and,

impeded the progress of a bartender when dispensing drinks. As a result of these defects, no one of the prior art bottle sealing devices has been used extensively for its intended purposes.

A major object of the present invention is to provide .a stopper that may be removably mounted in the mouth of a bottle to effect an airtight seal, but one that has a spout mechanism associated therewith through which liquor from the bottle may be readily discharged by a simple manual operation.

Another object of the invention is to supply a combined stopper and Huid dispenser of simplified structure, one that may be fabricated from standard commercially available material, and due to its low cost of production may be sold at a sumciently attractive price as to en courage its wide-spread use.

A still further object `of the invention is to furnish a combined stopper and Huid dispenser for a bottle that prevents alcohol containing fluids situated therein from i evaporating or becoming contaminated with alcohol absorbed from the atmosphere.

Other objects and details of the invention will be apparent from the following description, when read in connection with the accompanying drawings wherein:

Figure 7 is a vertical cross-sectional view of a portion of the actuating mechanism; and

Figure 8 is a vertical cross-sectional view of an alternate form of my invention.

Referring now to Figures l, 3 and 5 for the general arrangement of the invention, it will be seen that it includes a resilient stopper S that may be deformed the desired amount to provide a Huid-tight `seal when disposed in the mouth portion M of a bottle B. Stopper S is formed with a longitudinally extending bore A through which a tubular member T extends, which member terminates on its upper end in a spout C. A spring-loaded vertically movable air vent V extends downwardly through tubular member T to the confines of bottle B.

Air vent V, due to the spring-loading thereof, normally has the upwardly disposed entrance N thereto sealed by it engaging a seat E. An annular sealing member F mount* ed on air vent V normally seats in the lower entrance into tubular member T.

The invention is provided 'with three equally spaced, radially disposed claws l, which may be moved to removably engage a bead formed on bottle B by rotation of a headpiece L. Rotation of headpiece L causes the claws I to grip bead K and the stopper S to be concurrently expanded to effect an air and duid-tight seal with the interior surface of mouth portion M as will hereinafter be explained in detail. y

Stopper S is formed from a resilient material such as rubber, and in the non-deformed condition has `downwardly and inwardly tapered side walls it?. An annular plate 11 formed with a centrally disposed opening l2 is provided, which opening develops into a short upwardly extending tubular boss 13. The boss 13 has threads 13a formed on the interior thereof.

Plate l1 abuts against the lower surface ida of stopper S, with the boss 13 projecting upwardly in bore A. Tubular member T is held in an upwardly extending position within the confines of bore A by threads ld formed on the exterior surface of the member engaging the threads 13a of the boss as may best be seen in Figure 5.

A second annular plate l5 is provided that seats on the upper surface 10b of stopper S. Plate l5 is formed with a centrally located opening 16 through which 'tubular member T passes. The plate 15 as shown in Figure 4 has three equidistantly located sets of guide pins 17 and 17a extending upwardly from the top surfaceV thereof. The pins 17 and 17a forming each set are circumferen 'armen' tially spaced from one another a suiiicient distance to slidably engage an elongated strip 1S. Each of the strips 18 forms a part of one of the bead engaging claws I. ln Figures 3 and 4 it will be seen that the outer end portion of each strip 1S is bent downwardly to form a bead engaging portion 18e. y

Each strip liti has an elongated transversely disposed slot 19 formed on the inwardly disposed portion thereof. Each slot has an enlarged slightly inwardly extending end portion 19a the purpose of which will later be explained.

in Figure it will be seen that an internally tapped collar 20 is threaded on the upper portion of tubular member T. A horizontally disposed rod 21 of relatively short length extends outwardly from collar 20 and slidably engages a vertically curved groove 21a. The grooved 21a is formed on the. interior surface of a bore 2lb that extends downwardly through the centra] portion of headpiece L.

Three circumferentially spaced `pins 22 extend Idownwardly from the under surface of headpiece L. Each of the pins 22 slidably engages one of the slots 19. Headpiece L may take a variety of for-ms, but a generally circular shape having a handle 23 forming a part thereof as shown in Figure l has been found quite satisfactory.

Upon the headpiece L being pivoted in a counterclockwise direction, the pins 22 slidably move in slots 19 to draw claws J inwardly until the inwardly disposed edges of strip 1d occupy the positions shown in phantom line in Figure d. The strips 18 when in the inwardly disposed positions have the end portions 15a thereof gripping the bead K of bottle B. As the strips 18 assume their most inwardly disposed positions, the lpins 22 move into the slot portions Ma. Pins 22a are removably locked in slot portions 19a due to the slight inwardly extending positions thereof, and will not be displaced therefrom until pressure is exerted on handle 23. Thus, the possibility of the claws I being inadvertently displaced from a bead gripping position is eliminated.

As the headpiece L is rotated the rod 21 is slidably moved in groove 21a. This movement of rod 21 in the vertically curved groove results in downward pressure being applied to plate 15 through the pins 22. Plate 15 as pressure is applied thereto is forced downwardly, with stopper S being compressed between

plates

11 and 15. The stopper S as pressure is applied to the ends thereof deforms, and changes from the shape shown in Figure 3 to that illustrated in Figure 5. When the stopper S is disposed in the lmouth portion M of a bottle B, the radial deformation of the stopper by application of pressure thereto as above described assures a fluid and airtight seal between the contacting surfaces of the stopper and bottle mouth portion. Thus, rotation of headpiece L serves a dual function, that of moving claws I to a bead engaging position, and expanding the stopper S to completely seal the mouth M of the bottle.

The spout C is angularly disposed relative to the tubular member T, with a horizontal platform 30 being formed at their junction. Airvent V includes a rigid tube 31 of relatively small internal diameter which extends downwardly through the tubular member T. An upwardly disposed portion of tube 31 projects through and is slidably supported in a vertical bore 32 formed in the platform 30. Tube 31 has a horizontal disposed trigger 33 mounted thereon. The trigger has a vertically disposed bore 34 formed therein in which the extremity of tube 31 is inserted. A counterbore serves as the entrance N to airvent V. An outwardly extending Istop 35 is aiiixed t0 spout C, and is located directly above trigger 33. A cornpressed helical spring 36 encircles the portion of tube 31 above the platform. The spring 36 as it tends to expand exerts a force against the upper surface of platform 30 andthe lower portion of trigger 31 to at all times urge the tube entrance N into airtight contact with seat E. The seat E as may best be seen in Figure 5 extends downwardly from the main body portion of stop 35.

In Figure 5 it will be noted that a guide 37 in the form of a ring is rigidly axled to tube 31. The guide ring 37 is of such diameter as to be slidable within the confines of tubular member T. Guide ring 37 maintains airvent V in a fixed spacing relative to the interior surface of tubular member T, but does not appreciably obstruct the flow of iiuid through the member.

The annular sealing member F is rigidly mounted on airvent tube A, and is so vertically disposed thereon that movement of the airvent tube results in the entrance i0 to tubular member T being keither open or blocked by the sealing member. lt will be particularly noted in Figure 5 that airvent tube A is at all times urged upwardly by spring 36, with the result that entrance E and 40 are only open when pressure is exerted downwardly on trigger 33.

The use and operation of the invention is extremely sirnple. The device as shown in Figure 3 is placed in the mouth portieri M of a bottle B as illustrated in Figure l and the handle 23 then pivoted in a counterclockwise direction as far as possible. As pivotal movement of the handle 23 takes place, the headpiece L is rotated, with the stopper S being radially expanded to effect a iiuidtight seal with the interior surface of mouth portion M, and the claws I being drawn inwardly to grip bead K. The invention is now rigidly but removably aixed to the bottle B. It will be apparent that no fluid can escape from the bottle B when the invention is thus mounted thereon, nor can moisture be withdrawn from the atmosphere by the action of the fluid in the bottle, for the spring 36 at all times maintains member F and seat E in sealing positions.

Upon the trigger 33 being moved downwardly by application of pressure thereto, the airvent tube 31 is likewise moved downwardly. Downward movement of the airvent tube separates seat E and sealing member F from entrances to tube 31 and tubular member T respectively. When the bottle B is mounted and trigger 33 has pressure applied thereto as above mentioned uid may flow freely from spout C, with air entering the bottle through vent V to replace the space previously occupied by the dispensed fluid all air enters bottle B for pressure equalizing purposes through an airvent V, with the result that iluid is dispensed from spout C without bubbling or gurgling. Upon pressure being removed from trigger 33, the spring 36 immediately moves tube 31 inwardly to cause entrances N and 40 to be sealed by seat E and member F respectively.

An alternate form of my invention is shown in Figure S. This dispenser may be used on liquor bottles, and also mounted in the mouth of any bottle or container to maintain the contents thereof out of atmospheric contact except when iluid is dispensed therefrom. This alternate form of my invention is shown mounted in the mouth portion of a bottle 101, but it should be clearly understood that the application of the preferred form or the alternate form of my invention is not limited to this particular type of fluid dispensing device.

Referring to the drawings, it will be seen that the alternate form of fluid dispenser includes a tubular body 102 having a primary tubular pouring spout 103 extending downwardly through a centrally disposed bore 104 formed in a frusto-conical stopper 105. T he stopper may be formed from cork, rubber, or other resiiient material not adversely affected by fluid contained in the bottle with which it is associated. At an intermediately located junction 106, the primary pouring spout 103 branches into an upwardly extending tubular member 107 and an angularly disposed secondary pouring spout 103. The upper end of tubular member 107 is closed by a plate 109 from which a centrally disposed stem 110 depends. Stem 110 supports an annular packer 111 on the lower end thereof.

The portion of tubular member 107 directly above junction 106 is sealed by a plug 112 inwhich a longitudinally extending bore 113 is formed. An elongate air tube 114 is mounted in bore 113 and is vertically slidable therein. Stem 110 projects downwardly into tube 114 and maintains packer 111 in slidable sealing contact with the interior surface thereof. A collar 115 is mounted on the upper portion of tube 114, which collar is disposed within the confines of tubular member 107 and in slidable contact with the interior wall surface thereof, A handle 116 projects from collar 115 and passes through a vertical slot 117 formed in tubular member 107. Handle 116 may take a variety of shapes, but I prefer that of a generally L-shape as shown in Figure 8. This L-shaped handle includes a stem 11S which supports a concave pressure plate 118e at its lower end, which plate may be of any desired shape.

A helical spring 120 that is constantly in compression is disposed within tubular member 107. The upper end of spring 120 contacts the lower face of collar 115, and

`the lower end of the spring bears against a packing washer 121 positioned on the upper surface of plug 112.

ln Figure 8 it will be seen that an annular Valve member 122 is provided which has a bore 123 extending therethrough to permit mounting thereof on the lower extremity of tube 11d. Valve member 122 is at all times urged upwardly due to the compression on spring 120, and seats in fluid-sealing contact with the lower edge 122a of tube 11d as shown in solid line. A first air vent 124 is formed in tube 114 and so located that when my invention is in a non-dispensing position the vent may be seen above packer 111. A second air vent 125 is formed in the lower portion of tube 114 situated above valve member 122. A plug 126 or other conventional sealing means closes the lower end of tube 114. A flange 127 projects from primary spout 103 which limits the distance the spout may move downwardly relative to stopper 105. Flange 127 is also of assistance in forcing the stopper 105 down-l wardly into the mouth i) of the bottle or container with which my invention is associated.

The operation of my invention is extremely simple. When it is desired to dispense fluid from a container on which my invention is mounted, the container is inverted and the handle 116 moved downwardly. Downward movement of the handle causes tube 114 to move relative to packer 111 whereby the air vent 124 is moved from the position shown in solid line to that indicated in phantom line. Downward movement of tube 114 also breaks the lluid sealing contact between member 122 and seat 122m by causing member 122 to assume the position shown in phantom line (Figure 8).

Fluid may then flow into the primary spout 103 from where it is directed into the secondaryspout 10S. A constant air pressure is maintained within bottle 101 due to the fact that air is immediately substituted for fluid as discharged. When uid is discharged from the bottle 101, air enters tube 114 through air vent 124, and ows through tube 114 to enter the bottle through air vent 125. After the desired amount of fluid has been discharged from bottle 101, pressure is released from handle plate llllta, and compressed spring 120 returns tube 114 to the position shown where valve member 122 is in Huid-sealing engagement with seat 122e and vents 124 and 125 do not` communicate. ln practice it has been found desirable to have the internal diameter of secondary spout 108 somewhat less than the internal diameter of the primary spout 1d?, as this positively assures filling of the secondary spout with fluid and there is no tendency for air to pass up.

wardly therethrough.

Although the invention herein shown and described as fully capable of achieving the objects and providing the advantages hereinbefore mentioned, it is to be understood that is merely one embodiment of the invention, and that there is no intention to be limited to the details of construction thereof other than as dened in the appended claims.
