Definitions

  • This invention relates to aseptic filling of containers used to package flowable material such as orange juice, applesauce and the like.
  • containers used to package flowable material such as orange juice, applesauce and the like.
  • Such containers ordinarily are formed in a cuplike configuration of plastic, paperboard, metal, glass or other material and are closed in a sealed condition by a suitable lid.
  • Known container filler mechanisms include nozzle means which is disposed above a container to be filled so that flow of material into the container frequently is accompanied by undesirable splashing and spraying or misting and closure means for such nozzles is sometimes not entirely effective and permits dripping of the flowable material following the completion of a container filling operation.
  • Such splashing and dripping is highly undesirable because it affects the accuracy of fill and also interferes with the sealing of the container by a sealing lid and may result in a defective seal which leads to contamination of the contents of the container.
  • Known arrangements include reciprocating mechanisms in which a piston rod is exposed to atmosphere during some portion of the cycle with obvious potential for contamination. Other known devices simply utilize a continuous flow of product which introduce product directly to the container and which may thus interfere with sealing.
  • the prior constructions do not offer a filling device having a filling nozzle which allows splash free filling by reciprocal movement of the nozzle while isolating the nozzle from atmosphere to a sealing arrangement which allows flowable material to be discharged under aseptic conditions.
  • the invention provides apparatus for aseptically filling a container said apparatus comprising a reciprocal nozzle adapted to introduce sterile flowable material into the container, a housing disposed about said nozzle, aseptic means to supply said sterile flowable material to the interior of said nozzle including a transfer cavity within said housing and disposed about said nozzle US-A-3,334,668, characterised in that said container is disposed within a sterile walled enclosure structure pressurized with a sterile inert gas, in that said nozzle is reciprocally mounted in an aperture formed in a wall of said structure, in that said housing is secured to said wall in fluidtight relationship therewith, a rolling seal being secured in fluidtight relationship to the interior of said housing and to the exterior of said nozzle forming a fluidtight cavity therebetween and isolating said transfer cavity from atmosphere, means being provided for supplying inert sterile gas under pressure somewhat above atmospheric pressure to said fluid-tight cavity and in that said aseptic means includes at least one aperture in said nozzle forming a
  • Fig. 1 is an overall block diagram which represents the major components of the invention
  • Fig. 2A is a side view of a mechanism constructed according to the invention and which represents the nozzle in its uppermost position and the measuring piston in its lowermost position upon completion of a nozzle charging operation
  • Fig. 2B is a view similar to Fig. 2A but which shows the parts in-the positions which they occupy with the nozzle in its lowermost position at or shortly after the beginning of a container filling operation and with the measuring piston in its uppermost position at the beginning of a nozzle charging operation
  • Fig. 3 is a cross-sectional view of the measuring cylinder and piston which are shown in Figs. 2A and 2B
  • Fig. 4 is a cross-sectional view of the nozzle and its closure element and operating means
  • Fig. 4A is an enlarged view of a fragmentary portion of Fig. 4.
  • Fig. 1 the schematic arrangement of Fig. 1 includes a reservoir R the interior of which is isolated from atmosphere and in which flowable material is contained as well as sterile inert gas under pressure.
  • a conduit 7 and a check valve V interconnect reservoir R and measuring cylinder 1 the interior of which is isolated from atmosphere and which contains sterile inert gas under pressure.
  • Conduit 8 interconnects the interior of nozzle housing 2 and the interior of measuring cylinder 1 which is isolated from atmosphere and which is maintained under pressure of sterile inert gas so that flowable material may be supplied under aseptic conditions from reservoir R to cup C which itself is disposed in enclosure 3 in an aseptic environment of a sterile inert gas under slight pressure.
  • the numeral 1 generally designates a measuring cylinder and its associated structure and the numeral 2 generally disignates the nozzle and associated structure formed according to this invention.
  • the container to be filled is designated at C.
  • the measuring apparatus 1 and the nozzle structure 2 are mounted on and supported by a suitable base plate 3 to which a plurality of vertically disposed posts 4 and 5 are secured and at the upper ends of which a cover plate 6 is secured. Only two vertical posts 4 and 5 are shown in Figs. 2A and 2B. It will be understood that a corner post is provided at each corner of the generally rectangular base 3 and of cover 6, the front corner posts being omitted for clarity.
  • Base 3 defines the upper boundary of a sterile environment therebelow.
  • Generally speaking material to be dispensed into container C is supplied from a gas tight temperature controlled sterile reservoir R through an inlet conduit 7 into the measuring cylinder 1 as the measuring piston moves upwardly and thence through conduit 8 to nozzle structure 2 from which the flowable material is discharged into container C.
  • a check valve V having a housing 25 is connected with conduit 7 and includes a cavity 25a in which a cylinder 25b is slidable. Cylinder 25b is closed at is right hand and as indicated at 25c and includes a plurality of apertures 25d.
  • a compression spring 25e biases the cylinder 25b toward the left as viewed in Fig. 3.
  • This check valve is arranged to allow flow from left to right and to be sealed against flow in the opposite direction.
  • measuring cylinder 10 is secured in fluid tight fashion by sealing means such as O-ring 26 to the base structure 27 and piston rings 9a provide a sliding seal between measuring piston 9 and measuring cylinder 10.
  • measuring cylinder 10 The upper end of measuring cylinder 10 is provided with a flange 28 which cooperates with the flange portion 29 of tube 30 which is clamped in place by a two part clamping device 31 which is of conventional construction.
  • a rolling seal is provided and comprises a diaphragm membrane 32 having a central aperture through which the threaded stud 23 projects. From Fig. 3 it is apparent that the inner portions of membrane 32 are clamped between piston rod 24 and piston block 22 which is screwed down via the threads 23a into firm contact with the upper end of piston rod 24. The outer edge of membrane 32 is clamped between flanges 29 and 28 in fluid tight relation.
  • the interior of the upper portion of measuring cylinder 10 above measuring piston 9 and below the rolling seal 32 is supplied with a sterile inert gas such as sterile nitrogen through the inlet conduit 33. Pressure of this gas above piston 9 and below the rolling seal 32 is maintained at a level somewhat above atmosphere so as to preclude the entry of contaminating material from ambient atmosphere into the interior of measuring cylinder 10 above piston 9.
  • a sterile inert gas such as sterile nitrogen
  • the stroke of measuring piston 9 and the quantity of flowable material drawn into the measuring cylinder 10 is determined by the length adjustment of pivot arm 12 via its threaded portions 15 so that the greater the upward travel of piston 9 the greater the quantity of material drawn into the measuring cylinder 10 through conduit 7 and check valve 25 as is obvious.
  • Downward motion of measuring piston 9 forces the flowable material disposed therebelow outwardly through conduit 8 and its associated conduit 34 which is interconnected by clamping couple 35 with conduit 8 and which is arranged to discharge material to be dispensed into the nozzle structure 2.
  • Nozzle structure 2 is shown in cross section in Fig. 4 in a discharging condition during which upward movement of the nozzle takes place in order to prevent splashing of the material dispensed into the container C.
  • the lost motion relationship between the left hand end of operating arm 38 and cross pin 20 permits upward movement of the nozzle structure 2 which is independent of but coupled with the movement of measuring piston 9 as is apparent from Figs. 2A and 2B.
  • housing structure 45 is provided with a lower flange 46 which is secured by bolts 47 to base 3. Housing 45 thus is fixed in position while the nozzle structure is slidable vertically inside housing structure 45.
  • nozzle structure is a composite assembly made up of a number of parts.
  • the lower part of nozzle 48 is provided with an outwardly bevelled outlet indicated at 49 and a cone shaped upper portion 50 of closure element generally designated at 51.
  • a peripheral groove 53 is formed in a cylindrical lower portion 52 of the closure element 51 and a yieldable sealing element such as an 0-ring 54 is mounted in groove 53 and during closed condition engages the outwardly bevelled inner surface 49 of the nozzle 48.
  • a yieldable sealing element such as an 0-ring 54 is mounted in groove 53 and during closed condition engages the outwardly bevelled inner surface 49 of the nozzle 48.
  • Closure element 51 is secured to vertically reciprocable rod 55 so that when the closure element is in its down position as represented in Fig. 4 material may be dispensed into container C.
  • the closure element 51 When the closure element 51 is in its up position with the O-ring 54 in engagement with the lower portion of the bevelled surface 49 the lower end of the nozzle is closed in a leak proof fashion because of the engagement of the O-ring with the lower portion of the bevelled surface 49 which provides an annular cavity immediately below the O-ring for accumulation of any excess flowable material by capillary action thereby to prevent dripping.
  • Surface 50a slidably engages surface 48a to shear any solid pulp or other material which might tend to foster dripping of liquid or to cause opening of the valve.
  • Flowable material fed into conduit 34 enters transfer cavity 56 formed about the nozzle 48 and defined by the somewhat enlarged inner surface of housing 45. Apertures 57 and 58 are provided in the nozzle 48 and allow the passage of flowable material from the transfer cavity 56 to the inside of tube 48 and about the operating rod 55. When the valve is open this material flows into container C in the direction indicated by the arrows 59. Ribs 60 and 61 are formed along the upper surface of the cone shaped portion 50 so as not to form an umbrella as the material flows outwardly in the direction of the arrows 59. Such an umbrella causes the capture of gas which could agitate and possibly splash the flowable material.
  • the nozzle 48 occupies its lowermost position and the closure element 51 is open as shown in Fig. 4.
  • nozzle 48 is elevated while the closure element 51 remains open.
  • Pressure fluid disposed above the piston of the fluid motor 63 drives the nozzle 48 and the closure element 51 downwardly in unison. Elevating motion is imparted to the nozzle 48 by the down stroke of the piston 9 and of rods 18, cross pin 20 and element 38.
  • valve opening motion is effected by valve opening piston 65 which is secured to the rod 55 and which is vertically slidable within valve opening cavity 66 formed within tube 67 which is threadedly secured at 68 within the upper portion of nozzle 48.
  • Pressure fluid for valve opening piston 65 is introduced into opening cavity 66 through a conduit 69 and the hollow interior portion 70 of valve rod 55 through parts 71 and 72 to the upper working face of piston 65.
  • 0-ring 73 facilitates the seal between the periphery of valve opening piston 65 and the interior surface of valve opening cavity 66.
  • a flexible diaphragm having a central aperture 75 is provided with a central opening clamped between lower part 55a of rod 55 and upper part 55b of rod 55 while the outer periphery of flexible seal or membrane 75 is securely gripped between the shoulder 76 of nozzle 48 and the lower end of tube 67 due to the threaded relationship as indicated at 68 whereby tube 67 is screwed firmly into contact with the periphery of membrane 75.
  • valve closing cavity 78 is formed within tubular element 79 which is threaded at 80 to the outer upwardly extending portion of tube 67 and fluid pressure is supplied to valve closing cavity 78 through conduit 81.
  • Valve closing piston 82 is threadedly related as indicated at 83 with the upwardly extending outer hollow portion of the valve rod 55 and is provided with a piston ring such as an 0-ring 84 so that pressure fluid supplied through conduit 81 to valve closing cavity 78 effects upward movement of valve closing piston 82 and of the rod 55 which in turn effects closing of the closure element 51.
  • an adjustable stop 85 is threaded as indicated at 86 with the exterior surface of the upper part 82a of piston 82.
  • the valve closure element 51 may move downwardly a greater distance than such element can move if the stop element 85 is lowered or screwed downwardly relative to part 82a so as to engage the upper end 79a of tube 79 and thus to allow a lesser degree of downward opening movement of valve closure element 51.
  • a rolling seal 91 having a central aperture disposed about the upper end 67a of tube 67 is arranged so that the inner periphery of this rolling seal 91 is clamped between the shoulder 57b of tube 67 and the lower end of tube 79, such clamping action being effected by the threads 80 as is obvious from Fig. 4.
  • the outer edge portion of the rolling seal 91 is clamped between flange 45a of tube 45 and flange 95a of tube 95 by a conventional two-part clamp device 96.
  • Rolling seal 91 and diaphragm 75 serve to isolate the transfer cavity from atmosphere.
  • suitable control mechanism may include solenoid actuated pneumatic valves. If desired such pneumatic valves may be mechanically actuated.
  • an operating rod 102 shown in Figs. 2A and 2B is pinned at 103 with operating arm 38 and thus is reciprocated vertically through an opening formed in top cover plate 6 so as to come into engagement with a switch element schematically represented at 104 and mounted on suitable support structure 105 disposed atop the cover plate 6.
  • a switch element schematically represented at 104 and mounted on suitable support structure 105 disposed atop the cover plate 6.
  • Actuation of device 108 actuates an - electric solenoid or other suitable device such as a pneumatic valve so as to allow pressure fluid to enter through the conduit 81 into the valve closing cavity 78 so that pressure on the lower surface of piston 82 imparts upward valve closing movement to valve rod 55 and to closure element 51 relative to nozzle 48 so that the element closes the outlet end of the nozzle as the nozzle reaches its uppermost position.
  • a pneumatic valve such as a pneumatic valve
  • the apparatus is self draining since liquid material in cylinder 10 may flow through conduit 8, transfer cavity 56 parts 57 and 58 and outwardly through nozzle 48 when the closure element 51 is open.
  • the device may be sterilised with steam, hot water or other aqueous liquid sterilant.
  • this invention is primarily intended for use in filling containers such as plastic, paperboard, glass, metal or other containers with flowable material such as orange juice, apple juice, and the like and that the invention is particularly adapted to ensure aseptic conditions for packaging a product due to the concept of isolation of product areas form actuating means by the sealing arrangement 91 and 75 and in part to the isolation of the open container and its contents from ambient atmosphere and also due to the fact that during filling, spraying, splashing and dripping following closure of the nozzle by the valve closure means are prevented so that a proper seal can be achieved between the open upper end of the container and its lid.
