While different types and shapes of containers might be filled and sealed by the apparatus herein disclosed, in the embodiment of the invention illustrated a cylindrical container made from-heavy strong paper or light cardboard is shown. The cap or cover and the container are coated on each side with a lacquer, plastic or other substance which forms a waterproof coating. This lacquer is softened by heat and forms an effective sealing adhesive. While various lacquers might be used, in practice a lacquer formed of pigmented vinol has been found to be very satisfactory. 7

Referring to the drawings, particularly Figs. 1 and 2, a machine is shown having a guideway 15 in which the cylindrical containers 16 having open upper ends are moved. The containers 16 substantially fit between the sides 15a of the guideway 15 and are supported on the bottom of said guideway. A conveyor belt 14 forms said bottom, the same running over a pulley 17 suitably carried on the machine frame. Belt 14 will be driven by suitable means not shown.

Adjacent one end of guideway 15 is a revolving plate 18 mounted to rotate about a shaft 20, said plate being circularin outline and having semi-cylindrical circumferentially spaced recesses 18a in its periphery, said recesses being shown as three in number. Another member 21 is mounted for rotation on a shaft 22 and said member has a plurality ofvertically extending standards 21a carried thereon. Movable vertically on each of the standards 21ais a member 24 having a top platelike portion 24a which is shown in Fig. 2 substantially square in outline. As shown in Fig. 2, the inner and outer sides of the portions 24a are curved. Rods 25 are secured to the undersides of portions 240 and extend downwardly through members 24 and 21a and through member 21 and have secured to their lower ends cam rollers 26. Said lower ends are bifurcated and the rollers 26 are disposed in and rotate in the bifurcation of rods 25 and are mounted on pins or axles 28. The rollers 26 are arranged to engage the top of a stationary cam member 30 which is carried on the base portion 31 of the machine. As shown in Fig. 1, base portion 31 is supported upon a plurality of legs 32. The containers 16 are moved onto the plates 24a by the member 18 as the latter rotates.

A supply tank or reservoir 34 is provided, the same being carried upon a plate 35 having a depending central hub 55a. Hub a fits over the vertical shaft 36 which is secured to and rotates with shaft 22. Hub 35a is split at its bottom and can be clamped onto shaft 36 by the clamping screw 38. The bottom of tank 34 has secured thereto and depending therefrom a plurality of cylindrical members 34a illustrated as six in number. A cage member 40 is disposed over each member 34:: in axial alignment therewith, the same having circumferentially spaced leg portions and having an annular top portion. A tube 41 extends axially through cage member 40 and member 34a, the same having secured thereto spaced collars 42. A key member 43 shown in Fig. 6 embraces tube 41 between collars 42 and rests upon the top of member 40. Tube 41 is thus held in position. Tube 41 is open at its upper end and at its bottom end carries a cylindrical portion 414: of somewhat smaller diameter than the inside diameter of container 16. Member 41a has an upper portion of reduced diameter provided with an annular groove in its periphery in which a ring 44 is disposed, which ring acts as a valve. Tube 41 is cut away at one side as shown at 41b at its lower end. A cylindrical member 46 surrounds portion 340 and is secured thereto. Member 46 has a peripheral flange 46a and a lower tubular portion of reduced diameter which is open at its lower end. A member 47 surrounds said last mentioned portion and engages flange 46a at its upper side. Member 47 is shown as cylindrical and will be made of rubber or similar material. A compression coiled spring 48 engages the top of flange 46:: at its lower end and engages a nut 50 at its upper end, which nut is threaded on portion 34a and engages the bottom of plate 35.

Member 54 also has a portion 54a extending over member 21 some distance above the top thereof. Plate 54 also has a portion 54b extending adjacent to a shaft with which moves a member 57. Member 54 as shown in Fig. 1, has a thickness substantially the same as members 18 and 52. A plate 58 shown in dottedlines in Fig. 2 is disposed some distance below member 52 and rests on top of a standard: 31a, which upsta-nds from base member 31 and through which; shaft 53 extends. A nut 59 threaded on shaft 5 3v engages. the top of plate 58. Plate 58 is also supported. by a member 580 extending to frame 31. Member 54 is supported from plate 58 by a plurality of posts 58b. Bolts 63- extend through plate 54 into posts 58f. Plate 58 has a portion 58c disposed below portion 54a, a portion 58d onto which the containers move from trough 15 and a portion 58e onto which, the containers finally move.

Member 57 is mounted to rotate with a shaft 60 and has at opposite sides upstanding portions 57a forming guides for inverted cup-like members 61 having plate portions 61a at their upper ends. As shown in Fig. 2, portions 61a are of substantial sector shape. A rod 62 is connected to each plate portion 61a and is bifurcated at its lower end'to receive a, cam roller. 64 mounted on a pin 65 carried in said rod. Rollers 64 engage the top of a stationary cam member 66 mounted. on base member 31. Member 57 also carries upstanding portions 57b to which are secured the members 68 which are of semi-cylindrical plateelike form. Members 68 are secured by bolts 69.

Mounted some distance above each side of member 54 and member 61 is a sealing head 70 and a cap or cover feeding device 72. There are two of the sealing heads 70 and two of the cover feeding devices. Sealing heads 70 have flanges 70m at their sides secured to guideways 720 by bolts 7011. Each sealing head 70 has a guideway 721! secured thereto in which is movable a slide member 72b. Slide member 72b moves beneath a cylindrical container 720 in which the caps or covers 1611 are stacked one above the other, as shown in Fig. 14. Slide 72b has a downwardly extending pin 72d at its central portion to which is secured the central portion of a tensile coiled spring 72e which is secured at its ends to pins 72) respectively secured at each side of the guideway 72a. A member of arcuate form having a flange 73a at one side is disposed below guideway 72a, the same being supported on a standard 73a secured at its lower end to plate 58 and extending through member 54. Pin 72d extends downwardly through a slot 72b in slide 720 in position to engage flange 73a of member 73.

The sealing head 70 has a portion 70b at its lower end secured thereto by bolts 75. Another cylindrical member 71 engages the bottom of member 70b and is secured thereto by bolts 75. Member 71 has an annular groove 71b in its inner side in which is disposed a coiled spring 74 of small wire. Said portion 71b has walls extending outwardly and flush with the walls of guideway 72a. The slide 72b engages the lowermost cover 16a and moves the same, as illustrated in Fig. 14, into the member 71b so that the outer depending flange 16b of said cover is supported on top of spring 74, as shown in Fig. 14, and said cover is brought into position substantially in axial alignment with the head 70. Head 70 has a cylindrical member 70a to the lower end of which is connected a portion 70b having an opening therein with an upwardly and inwardly extending surface 700 which extends to a short cylindrical surface 70d. Said portion 70b is secured to head 70a by a plurality of circumferentially spaced headed bolts 75 having their heads countersunk in portions 70b. The lower portion of head 70a is counterbored and a portion 702' is disposed in said counterbore and engaged by member 70b. Portion 700 may also be engaged by one or more set screws 76. Portion 70a at its lower end has an outwardly and downwardly extending. surface 70f. A central member 70g is provided which is of general cylindrical form having a lower portion of slightly reduced diameter. Said member 70g is divided horizontally along the line 70h and a heating member 76 is disposed between the two parts thereof, the same being supplied with electrical current bythe conductors 78. Conductors 78 extend through an opening in the upper part of member 70g and through an opening in the upper end of member 70a. Member 70g has a central vertically extending portion 701' from which extends a portion 70 of greatly reduced diameter. A headed bolt 79 secures the parts of members 70g together. A compression coiled spring 80 engages member 70g at its lower end and engages the top of member 70 at its upper end, the same extending about and being held in position by portion 701'.

Member 70g has secured about the periphery thereof by small screws 82 a plate 83, the lower end of which is divided into a multiplicity of portions or prongs 83a having their lower ends rolled outwardly into a substantially cylindrical bead. An outwardly extending partly cylindrical head or bend'83b is formed'in portions 83a adjacent their connection with plate 83. Member 70:: has secured thereto and. extending, upwardly therefrom a. shaft 85, said shaft being shown as having a collar 85a thereon countersunk into the top of member 7011.

Shaft 60,. extends upwardly anda sleeve 86 is clamped thereto. Sleeve 86 is split and has. spacedlugs 86a through which extends a headed and nutted bolt 87.

Member 86 has adjacent its. top outwardly extending plate-like portions 86b. Shafts extend into and can move in openings in portions86b. Portions 85 have secured thereto by set screws 88a collars88 and stiif compression springs 89 surround portions 85 and engage collars 88 at their lower ends and portions 86b at their upper ends. Springs 89 are merely provided for safety in case excessive pressure should be applied to heads 70. Member 86 also has portions 86c fitting over portions 72c and having openings into portions 720 through which the caps or covers 160 can be placed in portions 720. A plate-like portion 86d extends between and overlies portions 860. Shaft 60 has areduced portion 60a extending through member 86, and a collar 86:: is secured to portion 60a and engages the top of member 86.

In Figs. 9 and 10 a die member 90 is shown which is divided into two parts along the line 90a, which parts are connected by a plurality of circumferentially spaced headed bolts 91, the same being shown as having their heads countersunk into member 90. The lower portion 90b of member 90 is also divided along-the line 900 and the parts thereof will be held together by a plurality of circumferentially spaced headed bolts 92 having their heads countersunk into the lower part of member 90. A heating element 94 is disposedin the parts of portion 90b and the same will be supplied with electrical current by conductors 95 which extend through suitable openings 90d in member 90. The lower portion 90b has an upwardly and inwardly directed surface 90c, the lower portion of which is provided with circumferentially spaced ribs 98 An inner die 98 is provided of frusto conical form having its outer surface extending outwardly and inwardly and preferably provided with a multiplicity of circumferentially spaced small ribs 98a. The ribs 98a and 90f do not have sharp or angular form in 'cross section but have a fiat curve formation as shown in Fig. 13. Die 93 has an upwardly extending central portion 98b of reduced diameter to which is secured a shaft 100 which is threaded at its upper end to be connected to a suitable carrier. A compression coiled spring of frusto conical shape surrounds portion 98b and shaft 100, the same engaging the top of die 98 at its lower end and engaging the upper portion of member 90, the upper end of said spring being disposed ina recess 90g formed in member 96.

in Fig. 12 a modification of portion 90b of the head shown in Figs. 9 and 10 is shown. In this figure member 90b is shown in two parts, the same being divided along the line 96b. The part 100 carries the heating element 94 shown in Figs. 9 and 10. The inner portion 101 has the same upwardly and inwardly sloping surface as portion 9% and has the corrugations 101d which are'identical with the corrugations 90f on portion 90b. An inner portion 101 will-be coated on its surface 1012 with cad mium, chromium, or similar metal. Such plating has been found in practice to give better results when the die engages the material of the container. Inner member 101 can be held in place by bolts 102 extending through portion 90 and having their heads countersunk therein;

In Fig. 13 the drive for the various parts of the machine is shown. As shown in Fig. 1, a bracket 105 is secured to and extends from frame member 31. Another bracket 106 extends vertically from bracket 105 and is arranged for horizontal sliding movement therein. A screw 107 having one end journaled in frame 31 is threaded in bracket 106 and provided with a crank handle 1'68. Bracket 106 has a top fiat surface to which is secured a driving motor 110. Motor 110 has a pulley 111 secured to its driving shaft over which runs a belt 112, also running over a pulley 114 secured to a shaft 115. Shaft 115 isv journaled in frame 31, as shown in Fig. 3, and has secured to its inner end within said frame a beveled gear 116. Beveled gear 116 meshes with a beveled gear 117 secured to a shaft 118, the upper end of beveled .gear 117 being formed as a chain sprocket 117a. A chain 120 runs around the. outer side of sprocket 117a and around the outer side of a somewhat larger sprocket 121. Sprocket 121 is secured to shaft 60. Chain 120 also runs around a small sprocket 122 which is secured to a shaft 123 suitably journaled in frame 31. Chain 120 runs around the inner side of a sprocket 124 which is secured to shaft 20. Chain 120 then runs around a sprocket 126 secured to a shaft 127 suitably journaled in frame 31.- Sprockets 122 and 126 are idler sprockets provided to hold chain 120 in engagement with sprocket 124. Chain 120 then runs around a large sprocket 127' which is secured to shaft 22. Chain 120 then runs around a small sprocket 128 similar to sprocket 117a and around a sprocket 130 which is secured to shaft 53. Sprocket 128 is an idler sprocket. The various sprockets will have a diameter to give the desired speeds to the various shafts.

In operation, the containers 16 with closed bottoms and open upper ends will be moved in trough 15 by conveyors 14. As the conveyors reach member 18 they will enter one of the recesses 18a and will then be moved as shown, by the container 16a in a circular path against member 54. As they come into position over the members 24, they will be deposited on the tops 24a thereof. Member 21 is rotated by shaft 22 and the conveyors are brought into position under one of the members 46. As member 21 moves, the roller 26 on the shaft 25 raises the particular member 24 upward, as said roller moves on the upwardly inclined portion of cam 30. The container is then moved upwardly with member 24 and engages the bottom of member 47 as shown in Fig. 5. This moves the bottom of member 46 away from the valve ring 44 and milk flows through the openings of cage 40, through portion 34a and member 46, into the container 16. As the container fills, the air therein can pass out through the opening in tube 41 which will extend above the level of the milk or other liquid in container 34. The container moves around with the member 35 and when it is filled it is lowered by the roller 26 moving down on the downwardly inclined portion of cam 30. Member 46 is moved downwardly by spring 48. as the container is lowered and the lower portion of member 46 engages ring 44 and shuts off the flow of milk. Portion 41a is provided to be sure that the right amount of milk is delivered to the container and that there will be some portion of the container above the level of the milk. The containers in their lower position on members 24 then come into engagement with member 52 and enter one of the recesses 52a and are moved around in a circular path against member 54 and onto one of the portions 61a. The filled container isthen raised, as the roller 64 on the shaft 62 secured to the member 61 travels up the upwardly inclined portion of cam 66. The container rotates with member 52 and the end 72d engages the flange 73a at cam 73 and the slide 72b is moved toward the head 70 which is rotating with member 57. The slide engages the bottom cap in container 72c and the same is moved into the head 70 and supported on spring 71b, as shown in Figs. 7 and 14. As member 86 rotates pin 72d engages the flange 73a of cam member 73 and said slide 72b is moved away from head 70. A cap can now be fed downwardly in front of slide 72b in guideway 72a. Pin 72d is then allowed to move toward head 90 by cam 73 under th tension of spring 722.

As the container moves upwardly, it is now accurately centered with head 70 by engaging the convex side of the spring 71b. It moves into the cap 16; as shown in Fig. 7. The container continues upwardly and the outer flange 16b of cap 16a engages the convex surfaces of the spring elements 83a. The container continues its upward movement and member 70g is moved upwardly. The surface 70 will engage the beads on members 83 so that the same will be moved inwardlyand the inner sides of the spring portions 831': are moved firmly against the outer flange 16b of the car: 1611. It will be noted that the lower part of member 70g fits in the cap 16c so that the inner and outer flanges 16b and 16c of the cap 1611 are pressed with considerable force about the upper portion of container 16. The heated member 70g causes the lacquer on the container and cap to act as an adhesive and the cap is very securely sealed to the container. The sealing heads 70 and the cap-feeding devices 72 continue to rotate, and after the container is sealed the member 61 on which it is carried is lowered by the roller 65 passing down the inclined portion of cam 66. The con tainer then reaches the level where its bottom is flush with the top of p'late 58. As the containers move in their circular path, the members 68 engage the same and successively move the filled and capped containers off of portion 61a and they move against member 54, as shown in Fig. 2, onto the plate 58 and around the flange 58e thereof as shown in Fig. 2. The filled containers can then be taken off the plate 58 and the desired disposition made thereof.

The sealing head shown in' Figs. 9 and 10 is a modified form of that shown in Figs. 7 and 8. When the head shown in Figs. 9 and l0 is used, the container will be moved upwardly as described and the outer flange of the cap 16a will engage the inclined surface 90a and be moved inwardly. Die member 98 will be engaged by the top of cap 16c and by relative movement of members 90 and 98 the inner and outer flanges of the cap will be very tightly pressed between the corrugations 90 and the cor rugations 98a. The die member 90 is heated by the heat= ing element 94' and the lacquer on the container and cap is heated and becomes an adhesive so that the upper part of the container and the cap are firmly and securely sealed together. The dies 90 and 98 give an inward inclination to the sealed top of the container. The sealed container is lowered on member 61a as previously described.

From the above description it will be seen that I have provided a comparatively simple yet highly eflicient method and machine for handling, filling, capping and sealing the containers. The containers are very tightly sealed. The containers have been found to be highly satisfactory for containing milk, orange and lemon juice, soft drinks, canned vegetables and fruits, and other fruit juices. Long tests have been made with various products and liquids in the containers and no leaks have developed. The original quality of the contents is preserved.

It will, of course, be understood that various changes may be made in the form, proportions and details of the apparatus and in the steps of the method Without departing from applicants invention, which generally stated, consists in a method and apparatus as set forth in the above objects and as disclosed herein and set forth in the appended claims.
