12 Claims. 1

This invention relates to improvements in devices ior dispensing liquid from bottles and measuring and recording the liquid dispensed. More particularly, the invention relates to a closure device which can be locked on a bottle and which is designedfor'use in connection with dispensing apparatus, such as is shownanddescribed in my pending application, Serial No. 740,353, filed April 9, 1947, for Liquid Dispensing Device. This dispensing device is designed to prevent unauthorized tampering with the contents of a bottle attached thereto and includes a'box containinga key-operated lock, a printing mechanism, a register, valves and valveoperating means. A tube projects upinto a bottle to support the bottle in an inverted position and to provide a passage for the discharge of liquid from the bottle to-a measuring cup secured 'to the bottom of the box. The dispensing device was designed to be locked as a unit to a bottle, thus making it necessary for a proprietor to have as many such devices as the number of bottles which mightbe needed during his absence.

It is an object of the present invention to reduce the quantity of apparatus required for any given establishment by providing simple closure devices for individual bottles which interlock and cooperate withdispensing apparatus so that any number of bottles to which such closure devices have been locked can be used in succession on one such-apparatus. The closure device includes a key-operated lock which can be unlockedby using a suitable key or by mounting the device on a dispensing apparatus of the kind referred to, having a key element which acts to unlock the closure so that a'passage may be opened from the bottle to the measuring cup which is apart of the dispensing apparatus.

The closure device embodying the invention, as illustrated in Figure 4, includes a member 20 which may be in the form of a rectangular block having a longitudinal groove or channel 22 with undercut side walls, as at 24, to slide on'acomplementaltrack 26 on a plate'28, such as the atop of a dispensing apparatus 3i], described 1 and illustrated in my "application, Serial No. 740,353. Projecting .up vfrom the block 20 is alsplitcollet 32 havinga :bore 33 which tapers near'itsupper end and-extends throughthe block 20. This collet maybe integral with a circular base 34whichris screw-threaded ina hole'through the block 20. In order to prevent unauthorized removal of the collet from the block 20, a-set screw 36 may be employed to lock the base =34 against rotation. Within-thebore 33 is a tubularspreader 38. A hole or notch 48 is provided in the wall of the spreader to receive a simple tool by which the spreader can be pushed upward to expand the upper end of the collet or pulled downward to allow the collet to contract.

section on the line 2fi20-o'f section on the line 2'l-2l of 3 The collet is surrounded by a suitable sleeve 42 of soft material, such as rubber, neoprene, or the like, so as to make a liquid-tight joint with the neck of a bottle 44 into which the collet is inserted.

The channel 22 in the bottom of the block is widened as at 46 to receive a closure element 59 which may be a thin but sufficiently rigid plate having its edges slidable in the wider portion 46 of the channel. Thus the slide 50 is held against the bottom surface of the block 20 and may be moved to close the hole through the block which provides a passage for the discharge of the liquid from the bottle. In order to make a liquid-tight seal with the slide 50, a suitable washer 52 is mounted at the lower end of the collet base 34, as indicated in Figure 5. The hole in which the collet base 34 is threaded is reduced in diameter where it opens through the bottom of the block, thus forming an inclined inner shoulder 56 against which the washer 52 is pressed by the bottom of the collet base 34 into a frusto-conical shape, so that the inner edge of the washer projects below the bottom of the block 28, as indicated in Figure 5. Thus, when the slide 50 is pushed in to close the bore of the collet, the inner edge of the washer 52 presses tightly against the slide to form a tight seal. Furthermore, when the device is mounted on the top of a dispensing apparatus 30, the Washer 52 engages the rim of a hole 58 in the top of the dispensing apparatus which communicates with a duct 59 through the apparatus, thus preventing leakage around the hole when the slide 56 is retracted.

The slide 50 is provided with a row of notches 60 along an edge thereof, these notches being arranged to receive tumblers 62 of a key-operated locking mechanism, shown in Figures 3, 7, 8 and 10. The tumblers 62 are vertically slidable in 7 suitable bores 64 in the block 20 and are preferably pressed by springs 65 which are held in place by a cap plate 68. Each tumbler 64 is made with a circumferential groove 10 at a selected level. As indicated in Figures 7 and 8, when the tumblers are in such positions that their grooves are on the same level with the slide 50, the slide can then be withdrawn. If, however, the tumblers or any of them are not on the level indicated, then such tumbler or tumblers engage in one or more of the notches 50 to prevent movement of the slide at from the block. In order to release the slide, a suitable key I2 is provided, as illustrated in Figure 4. The blade of the key maybe reproduced on the top of the dispensing apparatus, as indicated at 14 in Figure '7, so that when the closure device is slid into place on the top 28 so that the bore 33 of the collet is in line with the hole 58, the key blade 14, which is fixed on the top 28, will engage the plungers 62 so as to move the grooves I0 to the level of the slide 50, thus releasing the slide for movement to open the passage for the discharge of liquid from the bottle. Thus, when the closure device with a bottle mounted thereon is properly mounted on the top 28, the slide may be moved sufficiently to open the passage and permit liquid from the bottle to be dispensed in the manner described in my prior application. When the slide 50 is retracted, as shown in Figures 7 and 8, the margin of the slide engages in the grooves IQ of the tumblers, locking them against axial movement. Since the lower ends of the tumblers are thus held in notches in the edge of the key 74 (Figure 7), the block 20 cannot be moved as long as the slide is retracted. In order to remove the 4 closure device and bottle from the top 28, it is first necessary to push the slide 59 in to release the tumblers. This closes the discharge passage from the bottle.

When the closure device and bottle are removed from the dispensing apparatus, the tumblers shift axially as they leave the edge of the key 14 and the slide 553 automatically becomes locked in its passage-closing position until released by the use of a suitable key 12 which is to be kept in the possession of the proprietor. Thus, the plungers serve as an interlocking means to lock the slide 50 when the block 20 is slid off the top 28, or to lock the block ZII on the top 28 when the slide is withdrawn from its position across the discharge passage.

In order to facilitate the discharge of the liquid contents of the bottle and to prevent obstruction of outflow by bubbles of air rising through the discharge passage, a central, longitudinal partition 8B is provided in the hole 58, as indicated in Figures 5 and 6, and as described in the prior application. In order to supplement this partition 80, a similar partition 82 is mounted within the collet 82 to register with the partition 80, the partition 82 being secured to the base 34 of the collet and projecting up through the spreader 38. The partitions form two parallel passages extending from the interior of the bottle down through the neck and through the dispensing apparatus. When the discharge valve (not shown) is opened, an unbalance is quickly established in these passages so that liquid from the bottle flows downward in one of them while air flows upward in the other.

A modified form of the closure is shown in Figures 11 to 21. In this embodiment of the invention, the box top 28 is a plate on which is formed or secured a dovetail rail I00. A hole H12 extends downward through the rail and plate, to communicate with a conduit through the interior of the box 30. Extending from one end of the track I00 is a key member I04 which is preferably protected and concealed by a housing member I06 so that the key I04 is made difficult of access for inspection or duplication.

Slidable on the track I00 and removable therefrom is a block HG having a dovetail groove H2 in the bottom face thereof shaped to fit upon and receive the track Hi0. Slidable in the groove H2 is a dovetail slide H4 which is similar in shape to the track I09 and is adapted to be brought into abutting end-to-end relation with the track. The slide I I4 is provided with a longitudinal recess H6 to receive the housing I06 and the key I04 protected thereby.

A thin bottom plate H3 is secured to the bottom of the slide I I4 and is provided with a longitudinal slot I20 near a side edge thereof. A pin I22 projects from the bottom face of the block H0 and rides in the slot I20 to limit the range of movement of the slide H4 with reference to the block III) and to maintain the slide and block in assembled relation.

The slide H4 is preferably of the same length as the block I I0, and when its end faces are flush with the end faces of the block H0, the slide effectively closes a hole I24 through the top of the block I It.

Locking means are provided to maintain the slide H4 in this hole-closing position until released by means of a suitable key, such as the fixed key I04. As indicated in Figures 18 to 21, the locking means may comprise a series of flat tumblers I30 slidable in transverse slots I32 in accuses the slide H4 and corresponding slots I33 in the block IIO. These tumblers are spring-pressed-by suitable springs I34. Each tumbler I hasan intermediate upstanding lug I 30, the lugs on the several tumblers being variously spacedfrom the mid-point thereof. The edge of the key I04 isshaped in accordance with the spacing of these lugs so that when the key I04 is inserted in the longitudinal recess H0, its edge engages the lugs I36 of the tumblers and pushes them toward the left, as in Figure 18, against the pressure of the springs I34.

The contour of the key I04 is so shaped that when the key has been fully inserted in the recess H0, the tumblers I30 will then be accurately aligned so as to be clear of theslots I 33 in the block IIO, thus permitting sliding movement of the slide II4 relative tothe block IIO.

When theslide I I4 and the block I III are locked together, the hole I24 is effectively closed. In order to open the hole either for the discharge of :liquid from the bottle or, as hereinafter described, for the removal of the device from the bottle 'to which it is secured, it is first necessary to unlock the slide by the insertion of the key I04, or a similarly shaped key, into the recess II6. Since the key I04 is fixed on the box top 23, the block and slide are moved into operative relation thereto. This is done as follows. The bottle'being inverted as shown, the slide II4 is brought into alignment with the rail I00 on the top of the box and is then moved horizontally, with the block H0 and bottle, so as to cause the recess IIO to receive the housing I00 and key I04. When the end of the slide abuts the end of the rail, the key I04 is fully within the recess IIS and the tumblers I30 are aligned, thereby unlocking the slide from the block. The block can then be moved along onto the rail I00until thehole I24registers with the hole I02. Further movement of the block on the rail is stopped by engagement of the pin I22 with an end of the slot I20. When the block is in this position, the slots I33 do not register with the corresponding slots I32. Hence, the tumblers cannot move in their slots and the lugs I30 thus interlock with the edge of the key I04 to prevent removal of the slide and block from the top of the box until the block has first been moved back on the slide so that the slots I32 register with the correspondingslots I33.

In the top of the block is a tubular member I whichis screwed into the hole I24. The tube I40 is adapted to enter the mouth of a bottle 44 so as to provide a discharge passage for the escape of liquid from the bottle. In order to avoid leakage around the tube, it is preferably surrounded by a sleeve I42 of soft material, such as rubber or an equivalent. The screw-threaded base I44 of the tube I40 is preferably of a larger diameter than the rest of the tube. At the bottom of the base I44 is a rubber washer I46 which is pinched into frusto-conical shape so that its inner edge projects slightly below the bottom surface of the groove I I 2 and engages the top of the slide M4 to prevent leakage between the block and theslide.

In order to secure the block to the bottle 44, alocking-means is provided, as illustrated in Figures ll, 12 and 13. This consists of a transverse strip- I 47 which extends diametrically across the bore of the tube his at or near the lower end thereof. Secured to the cross-piece I4"! are two thin plates I40 and I50. These plates areparalleland extend diametrically across .thebore of 6 the :tubular member I40 .andzalso :project: upward. beyond the uppenendof the tube'for a substantial distance.

.Pivotallyqmounted between the upper :portions of the plates I4Band I50 are two wings I52 and I54. Also between the plates I48 and I50 is loosely mounted a wedgingmember I30 having a tapering upper portion I62 between the mutually opposed edges of the wings I552 and I54, .as indicated in Figure 11. The wedging member I50 has ahole I64 therethrough near'the lower end thereof, this hole being adap-ted'toreceive a simple tool (not shown) in the form of arshort hook which can be inserted-therein after the .tool has been thrust up through the boreoftheutube I 40. A push on'the tool moves-the wedging member I50 so that its tapered end I62 wedges the wings I52 and I54 outward until they engage tightly against the inner surface of the bottle neckat a point where the interior diameterfis greater than the interior diameter at the mouth of the bottle. This :wedging memberIGiI remains frictionally in place until it is retracted by axtool engaging in the hole I04. Since the wedging member I00 is accessible :only when the closure deviceis removedfrom the box :30 and when the slide I I4 is retracted to open the hole I24, the closure device cannot be removed from .the bottle to which it has been secured except by .a person havinga suitable key with which to .unlock the slide II4.

As is evident in Figure 12, the plates I48xand I50 constitute a diametrical partition extending from the partition within the box up :to .a, point well within the neck of the bottle, thus dividing the bore I24 into two parallel passages, so that air-binding of theliquidlisavoided. With such an arrangementthe liquid flows .rapidly down one of these parallel passages While .the air bubbles ascend the other passageto take the place of the escaping liquid.

The operation of this form of the inventiornis as follows. The proprietor, who has a suitable key with a contour similar to that of the key I04, unlocks the slide H4 and pushes it back until the hole 124 is open. The tubular member I40 is then pushed down into the mouth ofan upright bottle 44 as far as it will go. .A :tool.lis hooked into the hole I64 and is pushed until the wings I52 and I 54 are wedged awayfrom each other to engage the inner wall of vthebottle, as shown in Figure 11. The .tool is withdrawn and the slide is pushed back to itshole-closing position, as shown in Figure 17. The key.is .withdrawn, locking the block and slide. The bottle and the closure member are left in thislocked conditionfor use when wanted.

In order to dispense liquid from the :bottle 4'4, it is. inverted to thepositionshown on the :drawing'and the block I I0 with the slide .114 is;pushed on the top of .a box 30 :toward the track I00. The housing I00 enters the recess H3 and :the key I04 aligns the tumblers I30 so that whenxthe slide II4 abuts the end of the track 100, the blockAIIII is unlocked from theslide and-can be pushed along onto the track I00 to apositionin which the hole I24 communicates withthe .hole I02. The bottle is then ready to discharge its contents in measured doses by operation of the dispensing mechanism in the box 30.

The bottle 44 can be removed from the box 30 at any time by sliding the block back on the slide I-I4 until the ends of these members are flush. The slots I33 in the block IIO are :then in registry with theslots I32 in the slide H4 and the tumblers are free to move when released by the key I04. The block and slide can then be removed as a unit from the top 28 of the box and from the key I04 which is stationary. As the block and slide move clear of the key, the tumblers I30 are moved by the springs I34 from the positions shown in Figure 20 to the positions shown in Figure 21, thus locking the block and slide to each other.
