Patented Sept. 29, 1936 UNITED STATES PATENT OFFICE FILLING AND CLOSING MEANS FOR RECEPTACLES 62 Claims.

This invention relates to filling and closing means for receptacles, and more particularly to filling and capping apparatus for liquid containers such as milk bottles, or the like.

An object of this invention is to provide an improved apparatus for filling and closing receptacles. Another object is to provide an improved filling and capping apparatus for liquid containers such as milk bottles, or the like. A further object is to provide an improved bottle filling apparatus so constructed as to dispense with the use of valves and displacement means. Still another object of this invention is to provide an improved filling tube arrangement for such an apparatus and having associated therewith improved sealing means whereby the milk bottles or like receptacles are maintained sealed during the filling process, the seal being broken during the final filling operation thereby to prevent contact of the liquid with the sealing means. Still another object is to provide improved means for filling simultaneously a plurality of receptacles and having associated therewith improved means whereby the receptacles are filled to the exact level desired. Yet another object is to provide in an apparatus of the above character improved means for sustaining the receptacles to be filled independently of each other and including individual yieldable or resilient supporting means for each receptacle. A further object is to provide an improved filling tube arrangement and improved sealing means associated therewith thereby to provide fluid tight joints or seals at the mouths of the receptacles during the filling operation. A still further object is to provide improved means for supporting the receptacles during movement thereof into and out of filling and capping position and during the actual filling and capping operations and having improved means for holding and spacing the receptacles during such filling and capping operations. Yet another object is to provide improved means for effecting capping or closure of the receptacles subsequent to the filling operation, the improved capping or closure means being operated by elements of the receptacle filling means and by a common operating means. Another object is to provide an improved filling tube and sealing arrangement particularly adapted to use with liquid containers whereby contact of the liquid with the sealing means is wholly eliminated, thereby obviating any possibility of contamination of the liquid by direct contact with the sealing means. These and other objects and advantages of the invention will, however, hereinafter more fully appear in the course of the following description and as more particularly pointed out in the appended claims.

In this illustrative construction there is shown a receptacle filling and capping apparatus generally comprising a support herein in the form of a central standard or pedestal I! mounted on a suitable base or bottom support 2. Swivelly mounted on this pedestal l directly above the base 2 is a rotatable frame 3 having a plurality,

herein three, of radially projecting supporting arms 4. Mounted on and supported by each of these arms is the improved filling and capping unit generally designated 5. Swivelly supported at the upper end of the pedestal i above the filling and capping unit 5 is a rotatable liquid storage or supply tank 6. This storage tank is preferably circular in form, and, as shown most clearly in Fig. 7, is divided into four chambers 'l, 8, 9 and I9 separated by suitable radial partitions ll of different height, these partitions dividing the circular tank into the chambers l, 3 and 9 of equal capacity, the partitions being so formed that when liquid is poured into the initial chamber 7 the liquid overflows the adjacent partition when the chamber is filled and so on until the three chambers 1, 8 and 9 are filled to equal capacity, any overflow from the last chamber 8 being received by the overflow chamber H0. The chamber I8 is provided with a suitable operator-controlled valve l2 having an operating handle l3 whereby surplus liquid may be discharged from the overflow chamber at will. Each of the supply chambers l, 8 and 9 is provided with a similar valve i l and drain pipes whereby the liquid therein may be discharged to the filler units 5 at will, it being possible, due to the rotatable or swivel mounting for the filler unit supporting frame 3 to move the filler units beneath any one of the supply chambers l, 6 and 9 to receive liquid therefrom, as desired.

The filler units 5 are herein designed to receive a case of twelve quart size containers, although it will be evident that containers of a less or greater number and of different sizes may be employed, if desired and that the supply tank chambers may be designed to receive any desired quantity of liquid. It is also evident that instead of providing separate supply chambers in the supply tank, the latter may be provided with but a single large chamber containing sufficient liquid for all the filling units, or if desired a separate supply tank may be employed for each filling unit. The filling units are herein designed to accommodate pint and half-pint containers, and the supply tank or tanks may, if desired, be removed from the pedestal and replaced by a tank or tanks of suitable capacity, or detachable plugs or valves may be carried by the chamber partitions to vary the liquid level in the chambers and as a result to vary the chamber capacity to accommodate such pint and half pint containers. In any instance, the liquid is supplied to the filling units through suitable discharge pipes under the control of suitable operator-controlled valve means.

As above mentioned, there are herein disclosed three filling and capping units and three liquid storage chambers, one for each unit, although any desired number, more or less, may be employed.

Now referring to the improved filling and capping unit per se, it will be noted that supported on and suitably secured to an arm 6 of the swivel frame, as shown in Fig. 2, is a horizontal base plate It, and this plate has secured thereto, as by screws ll, upstanding side frames l8, 8. The outer sides of these side frames are vertically jecting downwardly through openings 25 formed in the supporting plate 2| are vertical filling tubes or nozzles 26 of the valveless type, herein twelve in number, one individual to each container to be filled, and each of these filling tubes projects upwardly a slight distance above the tank bottom in the manner shown in Fig. 2. The lower ends of these filling tubes are of reduced section forming a shoulder 27 against which is seated a metal washer 28 which forms an abutment against which a rubber sealing washer 29 engages, this sealing washer being conical in form and supported on and surrounding the reduced lower end of the filling tube. To suitably locate the sealing washer 29 on the filling tube thereby to vary the distance in which the filling tube projects within the container mouth, there may be interposed between the sealing washer and the metal washer 28 suitable rubber or metal washer shims 30, it being possible by inserting or removing these shims to vary the position of the sealing washer on the filling tube so that each sealing washer will evenly and with equal pressure engage the mouth of the container to be filled and thereby maintain proper sealing engagement with the container mouth, and the filling tube will projectthe desired distance into the container neck.

It will herein be noted that the containers disclosed-are in the form of milk bottles of the quart size, the particular bottles shown being of a standard design. It will be observed that in a standard milk bottle a bead 35 surrounds the sunken mouth 36 and an annular ledge or abutment 31 is formed within the bottle mouth adjacent the bead, and upon this ledge the closures, usually paper caps, are seated. The sealing washer 29 seats on this annular ledge 31 during the fillingprocess, so that even if the bead 35 is chipped or cracked, the bottle will still-be tightly sealed. The liquid in astandardmilk bottle usually assumes a levelslightly below this annular ledge 31 so that when the cap is pressed in position within the sunken mouth of the bottle the liquid will not be placed under pressure, a disadvantageous feature whereby possibility of liquid being forced around the edges of the cap results. This slight clearance also compensates for any expansionof the liquid due to temperature changes.

Again referring to the improved filling tube arrangement, it will be noted that arranged diagonally within each of the filling tubes is a vent tube 38 having a spoon mouth or-out-away portion 39 at its lower end extending substantially coextensively with the filling tube and each vent tube projects upwardly above the top of the filling tube and above the levelof the liquid in the filling tank 23. These vent tubes project downwardly to the bottoms of the filling tubes and each tube has a projecting lug engageable with the top of its filling tube toprevent the vent tube from slipping down through the filling tube. In the present instance there are provided six pairs of vent tubes, one for each of the twelve filling tubes,

and the tubes of each pair are held in position within the filling tubes by springs 39*. The vent tubes are obviously readily removable by simple withdrawal from the filling tubes for cleaning purposes. The spoon mouths of the diagonal vent tubes 38 prevent the trapping of air by the liquid fiowing over the vent tube mouths, the spoon mouths being cut back on the vent tubes to a point adjacent the tops of the filling tubes. If desired, the vent tubes may be omitted and the filling tube sealing Washers 29 adjusted relative to the filling tubes 26 so that the volumetric capacity of the filling tubes will be sufficient to retain liquid to effect filling of the bottles to the desired level. It has been found, however, that the use of the diagonal vent tubes greatly increases the filling speed. As shown in Fig. 1, the filling tank 23 of each filling unit is provided with an inclined inner wall 46] forming an overhanging lip at the rear end of the filling tank, this lip underlying the discharge pipe [5 of the liquid supply tank ii so that liquid may be discharged fromthe supply chamber directly to the filling tank under the control of the discharge valve. The inner lower end of the filling tank, that is the lowermost point in the tank bottom, is provided with an operator-controlled discharge valve 4! and drain pipe 42 so that when the milk bottles have been filled, any surplus liquid remaining in the filling tank may be discharged therefrom, the drain pipe 42 discharging such surplus liquid to a suitable tank 43 supported on the pedestal I as by a bracket 44 attached to the pedestal.

Now referring to the improved means for moving the upstanding side frames 28, 20 of the filling tank support along the guideways I9, IS on the side frames to raise and lower the filling tank to move the filling tubes and sealing washers out of and into their operative filling and sealing positions with respect to the bottles, it will be observed that pivotally mounted at 45 on the side frames it, one adjacent each side frame, are elements 46 having cam slots 41 and having attached thereto at 48 a U-shaped handle 49. Journaled on pin-like projections 50 secured to the supporting arms 26, 20 are rollers 5| which travel in the cam slots 41 so that when the operating handle 49 is manipulated and the elements 46 are swung about their pivots 45, relative movement between the rollers and cam slots occurs so that the cam slots force the supporting arms 25, 20 either upwardly or downwardly within their guideways thereby to move the filling tank 23 into its raised or lowered position. Pivotally mounted at 58 on the elements 46 are swingable lock elements 59, each having spaced notches Gil engageable with the pin-like projections 59 so that when the filling tank is in its raised position shown in Fig. 1, one set of the notches engage the pin-like projections to lock the cam rollers against movement relative to the cam slots, and as a result, positively precluding downward movement of the filling tank while when the filling tank is in the lowered container filling position the other set of notches lock the same in such position. These pivoted locking elements 59 are provided with a suitable operating handle 6! having its operating portion located adjacent the cam operating handle 49, as shown in Fig. 1.

The improved spring case and container transporting or transfer case will now be described. As shown in Fig. 2, supported above the bottom plate I6 is a horizontal slide plate 65 having its lateral edges guided in longitudinal grooves 66 formed in the inner sides of the side frames I8, i8. A stop 66 is provided on the frame 4 for limiting inward movement to the slide plate so that the containers are always positioned direct- 1y below the filling tubes. Secured to this slide plate 65 are coiled springs 61, one individual to each bottle, so that the bottles are independently resiliently sustained. Also secured to the slide plate 65 are the vertical walls 68 of the spring case, these walls being herein in the form of a fabricated metal structure and the spring case is provided at its opposite ends with suitable handles 69 so that the complete spring case and bottom slide 65 may be bodily removed from the bottom frame structure of the filling and capping unit. Also formed in the inner sides of the side frames [8 are longitudinal grooves 10 and 'Il arranged at different elevations with respect to the bottom grooves 66 so that the bottom slide plate 65 and spring case may be supported by the side frames at different elevations, thereby to accommodate bottles of the pint and half-pint sizes, instead of the quart size shown, in a manner to be hereinafter described. Insertible within the bottom spring case is a transfer case 12, as shown in Figs. 10, l1 and 12, this transfer case likewise being formed of suitable fabricated metal structure and having suitable handles '13. In the case shown, however, the interior thereof is divided into twelve sections by longitudinal and transverse partition rods 14 and 15 thereby providing an individual chamber for each of the twelve bottles. These chambers are open from end to end through the top and bottom of the transfer case, and to support the bottles therein during transport thereof, there are provided supporting members 16, herein in the form of crank rods rotatably mounted within the sides of the case and each having portions I1 projecting within the bottom of the bottle receiving chambers, thereby to form a bottom support for the bottles therein. These supporting rods are maintained in their supporting position by levers 78 held in position by a locking plate 19, this locking plate having a series of apertures receiving the levers 18 of the four supporting rods. This locking plate is maintained in looking position by springs 80 and is guided for its movement by pins Bl guided within a bracket 82 secured to the side of the case frame. When the transfer case, as shown in Figs. 10, l1 and 12, is filled with empty bottles, it may be inserted within the spring case, the latter being so formed as to receive the transfer case. When the transfer case is seated within the spring case, the springs 67 of the latter project upwardly through the bottoms of the bottle receiving chambers of the transfer case into positions wherein the bottles rest on the coil springs 61. When the bottles are so positioned within the spring and transfer cases, a holding and spacing frame 83 is placed over the bottle necks in the manner as shown in Fig. 2, and the opposite ends of this frame 83 are provided with spring catches 84 having locking projections 85 adapted to spring beneath the handles 69 of the spring case frame 68 to lock the frame 83 in its holding and spacing position and to maintain the transfer case down in the spring case.

When the spring case frame 68 is inserted within the bottom frame of the filling unit, as shown in Fig. 2, and the transfer case 72 is positioned within the spring case, as shown, the operator may grasp the handle 49 and move th latter upwardly a slight-distance to release the cam lock, the lock elements dropping into their released position by gravity. The operator then swings the handle $3 of the cam operating means downwardly to lower the filling tank 23 thereby to bring the sealing washers 29 in sealing engagement with the bottle mouths in the manner shown in Fig. 4 with the filling tubes projecting downwardly through the bottle mouths a substantial distance within the bottle necks. When the sealing washers are so positioned the bottles are resiliently held in sealing engagement with the washers by means of the coiled bottle supporting springs E51, the springs also serving as yieldable supports for the bottles thereby to elim inate the possibility .of bottle breakage. When the parts are so positioned the operator opens the discharge valve M of one of the supply tank chambers, thereby permitting the liquid to flow from the supply chamber through the discharge pipe l5 into the filling tank 23. The liquid flowing into the filling tank fiows through the filling tubes 26 into the bottles, the liquid flowing into the bottles displacing the air therein until the level of the liquid rises up to the level of the bottoms of the filling tubes, the air displaced discharging from the bottles through the vent tubes 38. The air trapped in the spaces above the bottoms of. the tubes 26 and below the sealing washers prevents further flow of liquid into the bottles. The spoon mouths 39 of the vent tubes permit free venting of the air from the spaces within the bottles below the bottoms of the tubes 26 even when the foam, caused by the liquid rushing through the filling tubes, rises a substantial distance within the filling and vent tubes. It will herein be noted that the vent tubes, due to their diagonal position within the filling tubes, act as separating means to deflect the milk into a plurality of streams so as to prevent excessive foaming of the liquid as it flows through the filling tubes into the bottles. When the level of the liquid in the bottles has reached the bottoms of. the filling tubes, the operator opens the valve 46 of the tank drain pipe 42 to permit any surplus liquid left in the tank to drain off. The operator then raises the lever 59, moving the filling tank upwardly and breaking the sealing contact between the washers 23 and the bottle mouths, the

liquid then remaining in the filling tubes flowing into the bottles substantially filling the space in the bottles left by the filling tubes when the bottles are sealed, the volumetric capacity of the filling and vent tubes being so determined as to completely fill the bottles to a level slightly below the cap ledge 31, ready for capping.

When bottles of the pint and half-pint sizes are used, instead of the quart bottles disclosed, the spring case is inserted in one or the other of the guideways 73, H in the side frames l8 thereby to bring the spring case into a different elevated position so that when the filling tank is moved downwardly, these bottles of different sizes may be filled in exactly the same manner as that above described. In certain instances, however, it has been found that the supporting rods E6 of the transfer case 52 permit the smaller bottles to drop down through the bottoms of the bottle receiving chambers, and to overcome this difiiculty there is provided, as shown in Fig. 22, a supplemental supporting container 88, one for each bottle compartment in the transfer case l2. These supporting elements each have a bottom opening through which the springs of the spring case'extend so that when the elements 86 are in position within the transfer case, the springs yieldably support the bottles as heretofore described. These supporting elements 86 are held within the bottle chambers by means of spring clips 87 engageable with the side frames and partition rods 14, 15 of the transfer case, thereby to hold the supports 36 in position. Different sets of these supplemental-supports 86 may be provided for bottles of different sizes. It will be evident, however, that the supporting rods 16 may be so formed as to accommodate bottles of different sizes, thereby obviating thenecessity of these separate supports. As the filling operation for the bottles of the pint and half-pint sizes is exactly the same as that described above in regard to the quart bottles, a repetition of the description of. the filling process for these different sized bottles is considered unnecessary.

Now referring to the improved capping device whereby the bottles may be capped by means operated by the filling tank raising and lowering handle, it will be noted that mounted on a suitable supporting structure 88 is a horizontal plate 89 carrying a plurality, herein three, of cap receiving tubes or magazines 90. Each of these tubes is provided with a flared upper end 9! to receive the cap container C and is vertically slotted at 92 so that as the caps are lowered into the cap tubes 99, the operator may insert his finger, or some suitable instrument, within this slot to control the movement of the caps down through the tubes. Slidable beneath the bottoms of the cap tubes 98 and guidedin a horizontal guideway on the supporting structure 58 is a horizontally disposed cap receiving plate 93. Secured to each of the cap tubes 98, as shown in Fig. 16, is a leaf spring 94 having bottom fingers Q5 movable inwardly within slots cut in the plate 93 to a position wherein the fingers underlie the bottommost caps to maintain the caps in the tubes when the plate 93 has been withdrawn from beneath the same. Secured to each of these leaf springs, at the rear side thereof, is a spring catch 96. When the cap receiving plate 93 is slid inwardly within its guideway beneath the bottoms of the cap tubes 95 upstanding lugs 91 on the rear end of the plate, as shown in Figs. 16 and 17, engage hinged elements 98 carried by transverse members 99 secured to the leaf springs 94 respectively, and these lugs 9? upon engagement with the hinged elements 98 push the leaf springs rearwardly to the dotted line position shown in Fig. 16, moving the fingers 95 from beneath the cap tubes, thereby to release the caps in the tubes. As the leaf springs 94 move into this dotted line position, the catches 9t thereon engage an element 19E] of the supporting structure 88 to hold the cap release fingers in such position. As the cap receiving plate 93 is slid into its rearmost position within its guideway the lugs 97 thereon engage a lever l0! pivoted on the supporting structure 88, and this lever upon engagement of an adjacent lug 91 with the same, swings freely rearwardly to permit the lug to pass beneath the same. When the lug has passed beneath this lever, the latter swings freely forwardly into a position in front of the lug. As the cap receiving plate 93 is slid toward its rearmost position and the cap release fingers are in their released position, the caps in the cap tubes are free to move downwardly so that when the cap receiving plate is so moved, each of the twelve openings in the plate receives a cap from the tubes. As the cap receiving plate 93 is withdrawnfrom its guideway beneath the-cap tubes,

the lug thereon engages the lever IOI to swing the latter forwardly thereby to release the spring catches 96 from the element I to permit the leaf springs to spring inwardly toward the cap tubes, and as a result bringing the release fingers 95 beneath the lowermost caps in the tubes. As the leaf springs swing down in front of the lugs 91 the hinged elements 98 swing forwardly about their pivots upon engagement of the lugs therewith to permit the lugs to pass forwardly beneath the leaf springs of the cap release means. The cap receiving plate is then completely withdrawn from its guideway on the supporting structure 88, and upon removal thereof a plate m2 is placed upon the same, this plate being held in position on the cap receiving plate 93 by means of an overhanging lip I03 formed on the lugs 91 at one side and a spring clip I04 on the other side in the manner shown in Fig. 18. Secured to the cap receiving plate 93 are twelve cylinderlike elements I05, one for each cap receiving opening, and each of these elements has formed therein a chamber I06 receiving a piston or plunger element I01. Each of these piston elements is provided with a projecting piston rod I08 having formed thereon an enlarged head I09 having a central recess H0. Interposed between the head I09 and the outer side of the cylinder element I is a coil spring I I l for holding the pistons I01 in their outermost released position. After the cap receiving plate 93 has been removed from the cap tubes 90 and the holding plate I02 has been attached thereto thereby to retain the caps within the receiving plate, the cap receiving plate is inverted and placed over the mouths of the twelve quart bottles in the spring case, the circular recesses H2 in the plate I02 seating directly on the tops of the bottles and maintaining the bottles in proper location during the capping operation. When the cap receiving plate is inverted, the caps therein are prevented from dropping away therefrom through openings II3 formed in the plate I02 by means of tapered portions or lips I I4 projecting inwardly to form a restricted opening of a size slightly less than the diameter of the caps. When the capping plate is in the position above described on the tops of the bottles, the operator swings the handle 49 downwardly to lower the filling tank until the bottoms of the filling tubes 26 engage the bottoms of the recesses H0 on the heads I09 of the pistons I01, and upon further downward movement of the filling tubes the plunger pistons are moved downwardly, forcing the caps through the restricted openings in the plate I02 into capping position on the annular ledges 36 of the sunken mouths of the bottles. It will thus be seen that the operating means for raising and lowering the filling tank not only controls the operation of the bottle filling means, but also effects operation of the bottle capping means.

In this instance the coil springs I I I of the cap ping plungers are under greater tension than the supporting springs of the spring case when the bottles are in filling position within the latter, so that when one or more of the bottles is of less height than the others, the springs support ing the high bottles will be compressed as the operating means for the capping plungers is lowered, so upon further lowering of the capping means, the low bottle or bottles will be properly capped; the high bottles being first capped and thereafter the low bottles being capped. By so proportloning the springs of the spring case and capping device it will be evident that bottles of varying height may be capped and without placing undue pressure on the bottles themselves, the spring case springs yielding as the capping device operating means is lowered into this low capping position.

When the bottles have been filled and capped the operator grasps the handles 69 of the spring case and removes the entire case unit, together with the bottles, from the filling and capping frame. These cases which are locked together are then released from one another simply by releasing the spring catches 84, 85 of the holding and spacing frame 83 from the spring case handles 50. The transfer case "I2 is then removed from the spring case and the spring case replaced in its operative position within the filling and capping unit frame. The transfer case is then placed into a standard delivery case, not shown, the locking element 19 upon engagement with a side of the delivery case moving upwardly into its released position as the transfer case is lowered within the delivery case, thereby releasing the levers 78 of the bottle supporting rods 16 permitting the supporting portions 11 thereof to drop downwardly, and as a result the bottles drop down through the bottom of the transfer case into the delivery case. The transfer case is then lifted out from the delivery case, and after refilling thereof with empty bottles, it is again placed into the spring case of the filling and capping unit, and the operations above described may then be repeated. If desired, a plurality of transfer cases may be employed so when one is being placed into the delivery case another may be placed with empty bottles into the spring case, so that during transfer of the filled bottles another case of bottles may be filled.

As a result of this invention, it will be noted that an improved apparatus is provided for filling andcapping containers whereby the containers may be filled to the exact level desired with great rapidity and without the use of separate valve means in the filling tubes and liquid displacement means in the filling tubes. It will further be noted that by the provision of the improved capping apparatus disclosed a case of bottles may be simultaneously capped by means operated by the same means as that which operates the container filling means. It will further be noted that by the use of the particular spring case and transfer case disclosed the handling of the containers has been reduced to a minimum. These and other uses and advantages of the improved filling and. capping apparatus will be clearly apparent to those skilled in the art.

While there is in this application specifically described one form which the invention may assume in practice, it will be understood that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
