Definitions

  • ABSTRACT OF THE DISCLOSURE sterilizing, filling and capping bottles by first preheating the exterior of a bottle while simultaneously evacuating its interior. Next the interior of the bottle is sterilized with steam and then again subjected to evacuation while the exterior is still heated so that any condensate within the bottle will boil off prior to filling.
  • the filling device is constructed to prevent steam from coming in contact with the filling tube and its valve member during the sterilization and the device is also provided with a seal which will act as a safety valve if the steam pressure becomes excessive.
  • This invention relates to the sterilization of bottles and the filling and capping of the sterilized bottles.
  • bottles includes cans and other like containers to be sterilized and filled.
  • An object of the present invention is to enable such condensate to be reduced to an acceptable level.
  • Another object of the invention is to provide a method and apparatus for dispensing a liquid into a sterilized bottle without contamination.
  • a method of sterilizing a bottle by means of steam under pressure which comprises pro-heating the bottle, from the outside thereof, within a container by initially passing the steam into and out of the container and then introducing steam into the bottle to sterilize the inside surface thereof, shutting off the supply of steam to the inside of the bottle, and allowing any condensate therein to boil off under the action of heat.
  • a vacuum is created within the bottle during the pre-heating thereof to remove air from within the bottle, which would otherwise prevent the steam from exerting its full sterilizing effect.
  • sealing means to prevent the steam from entering the bottle to restrict the formation of condensate.
  • a vacuum may also be created within the bottle after the the sterilization thereof, to supplement the action of heat in the removal of condensate.
  • the initial passage of steam out of the container is utilised to create the said vacuum during preheating.
  • the passage of steam into and out of the container may also be utilised to maintain the application of heat to the bottle during removal of condensate, and also, if desired, to create a vacuum within the bottle during such removal. It may be found in practice that sufiicient heat and vacuum may be maintained for the removal of condensate by shutting off the supply of steam to the container when sterilization of the bottle is completed and allowing the steam within the container to vent to atmosphere.
  • Apparatus for carrying out the foregoing method comprises a sealable container for housing the bottle, inlet and exit means for the passage of steam under pressiire into and out of the container, and steam-ejector means associated with the said means and adapted to permit the exit of steam, and the simultaneous creation of a vacuum within the bottle during the pre-heating thereof and controllable alternatively to divert steam into the bottle for the sterilization thereof and again to permit the exit of steam and the simultaneous creation of a vacuum within the bottle during the removal of condensate therefrom.
  • a method of sterilizing a bottle and dispensing liquid into the bottle comprising the steps of sealing a dispensing tube so as to prevent the fiow of liquid through the tube, locating a bottle relative to the dispensing tube, sterilizing the interior of the bottle with steam under pressure while isolating the steam pressure from the seal in the dispensing tube, venting the steam from the interior of the bottle to reduce the pressure, causing approach of the tube to the bottle and sealing the tube with the mouth of the bottle so as to isolate the interior of the bottle from its surroundings except through the tube, opening the tube to allow the liquid to flow from the tube into the bottle while still maintaining the bottle isolated from its surroundings except through the tube.
  • apparatus for sterilizing and filling a bottle with liquid comprising a sealable container for housing the bottle, a pedestal for mounting a bottle within the container, the container having inlet and exit means for the passage of steam into and out of the container, a first, two-position, steam control valve disposed in the exit means, the first value having two positions and being adapted in one position to permit the exit of the steam, and being adapted in the other position to divert stearn into the bottle, a second valve disposed above the container for controlling the flow of liquid into the bottle, the second valve comprising a tube and a plunger coaxially aligned with each other and with the container, the tube being adapted to be connected at its upper end to a source of liquid, the plunger being adapted to form a seal with the tube so as to close the tube, the tube and plunger on the one hand and the pedestal on the other hand being adapted for relative movement between first and second relative positions, means for effecting downward movement of the tube and plunger together from
  • third sealing means are provided which are adapted, when the tube and plunger are at their first position, to maintain a partial vacuum within the bottle.
  • a one-way safety valve is provided which is adapted in the event of failure of the first sealing means when the tube and plunger are at their first position, to allow the steam leaking past the first sealing means to vent to atmosphere so as to protect the seal between the tube and the plunger.
  • a sleeve is provided which is coaxial with the tube and the plunger and co-operates with the first sealing means to assist in isolating the seal between the tube and plunger from the bottle, and co-operates with the second sealing means to assist in isolating the bottle from its surroundings.
  • Another feature of the invention is the inclusion of means for capping the bottle after it has been filled (or partly filled if this is desired).
  • Another feature of the invention is the combination of the apparatus for sterilizing the bottle with the apparatus for dispensing the liquid into the bottle so that the sterilizing and filling can be done in a single apparatus.
  • FIGURE 1 is a sectional elevation of a simple form of apparatus for sterilizing a bottle with a single milk bottle in operational position
  • FIGURE 2 is a vertical section through one embodiment of the apparatus for dispensing liquid into a bottle
  • FIGURE 3 is a vertical section through another embodiment of the dispensing apparatus and,
  • FIGURE 4 is a vertical section through the same embodiment as FIGURE 3, but modified to include means for capping the bottle after it 'has been filled.
  • FIGURE 5 is a vertical section through a third embodiment of the apparatus for dispensing liquid into a bottle.
  • FIGURE 1 the bottle 1 is held in an upright position within a container 2, which is sealed (apart from its connections to inlet and exit ducts, in which valves 3 and 4 respectively are located) during the operating process.
  • the bottle opening is also sealed off from communication with the remainder of the interior of the container (except as will be mentioned later, via a steam-ejector device 6 and a vacuum duct 7) by means of a sealing disc 8.
  • the bottom of the container is sealed by ram 9, carrying a pneumatically-operated pedestal 11.
  • the bottle 1 is urged upwards against the sealing disc 8 by the pedestal 11.
  • the steam-ejector device 6 is capable of producing a vacuum in the bottle 1, via duct 7, when steam under pressure is passed through the container and out through the exit duct when valve 4 is open.
  • valve 4 is open. Saturated steam under pressure is introduced to the container through valve 3 and escapes through valve 4 after passing through the steamejector device 6. Steam pressure is thus maintained outside the bottle, while the steam-ejector maintains a vacuum within the bottle. The bottle is thus pre-heated during this stage, without any steam reaching the inside of the bottle to form condensate. The vacuum within the bottle facilitates the subsequent introduction of steam into the bottle, which is the next stage in the process.
  • valve 4 when the bottle is sufficiently pre-heated (say after a period of the order of seven seconds) valve 4 is closed, and steam is then introduced into the bottle through the steamejector device 6 and duct 7.
  • the inside surface of the bottle is sufficiently sterilized in about three seconds or so by the heat imparted by the steam and some condensate is formed in the bottle.
  • the only supply of steam tothe inside of the bottle is then shut off by the re-opening of valve 4, so that a vacuum is again created within the bottle, which continues to be heated from the outside thereof.
  • the condensate boils off under the action of heat, assisted by the vacuum.
  • valve 3 After a further short time interval (or even possibly without any such further interval) valve 3 is closed and the steam pressure within the container drops to atmospheric as steam escapes through valve 4.
  • the bottle can then be removed from the container, by lowering the ram 11 together with the pedestal 9 until the bottle is clear of the container 2.
  • the bottle is removed from the pedestal and the next bottle mounted on the pedestal by a convention conveyor system, for example a starwheel system.
  • a convention conveyor system for example a starwheel system.
  • the bottle will be left in the container and filled with liquid before being removed from the container.
  • FIGURE 2 shows one embodiment of apparatus for dispensing fluid into the bottle after it has been sterilized.
  • the bottle 1 remains in the same container 2 (only the top portion of which is shown in FIGURE 2) in which it was sterilized, the mouth of the bottle still being sealed against the sealing disc 8.
  • a header tank 12 is mounted above the bottle 1 for holding a supply of liquid, in this case, sterile milk.
  • the tank 12 has an orifice 13 in the bottom through which the sterile milk can pass into a tube 14.
  • the tube 14 is flexibly connected to the tank 12 by means of bellows 16 which surround the orifice 13.
  • the bellows 16 bias the tube 14 downwardly away from the tank 14, and a spring 17 can be provided between the tank 12 and the tube 14 to assist the bellows 16 in its biasing action.
  • the lower end of the tube 14 is closed by a cylindrical plunger 18 which is coaxial with the tube and axially movable so that it can be moved up to abut against the lower end of the tube.
  • the plunger 18 has a seal 19 on its upper surface which seals off the tube 14 thereby preventing milk from flowing out of the tube.
  • a rod 21 is arranged coaxially with the plunger 18 and passes up along the axis of the tube 14. The rod 21 can be moved axially by any suitable means to move the plunger 18 and thus open or close the lower end of the tube 14 as required.
  • a floating sleeve 22 surrounds the plunger 18 with only a small clearance between the sleeve and the plunger to minimize the volume of milk trapped during operation.
  • the sleeve 22 is provided with a seal 23 On its upper surface which seals with a shoulder 24 in the housing 26 when the sleeve 22 is forced upwards against the shoulder 24 by the force of the plunger 18.
  • the seal 23 can also form a seal between the sleeve 22 and the tube 14 when these two members are engaged.
  • the lower end of the sleeve 22 is bevelled both on its inner surface and on its outer surface. The bevel on the inner surface of the sleeve can engage with a seal 27 in the form of a protruding shoulder mounted on the plunger 18, and the outer bevel on the sleeve 22 can seal with the seal 8 mounted in the housing 26.
  • the bottle 1 is positioned in the container 2 in the housing 26 so that the mouth of the bottle abuts against the lower surface of seal 8. There is an annular space between the plunger 18 and seal 8 so that when the bottle 1 is in position as shown this annular space is in direct communication with the interior of the bottle.
  • the steamejector 6 (mentioned in connection with FIGURE 1) is provided in the housing 26 connecting with the annular space between the plunger 18 and the seal 8 and thence with the inside of the bottle 1.
  • the interior of the bottle is evacuated, pressurised with steam and vented through the ejector 6 and the annular space between the plunger 18 and seal 8 as described above.
  • Seals 27 and 23 retain both steam pressure and vacuum. If steam should leak past either seal during the sterilization it will not enter the milk through seal 19 but will escape to atmosphere past an internal distributor seal 28 which is mounted around the tube 14 which prevents the entry of contamination.
  • plunger 18 is lowered.
  • the sleeve 22, which is floating, moves down with the plunger 18 until the sleeve 22 engages with the seal 8. Further downward movement of the plunger causes the seal 27 to break, allowing a small amount of steam to pass into the space 'between the sleeve 22 and the plunger 18 to help to clean and sterilize this space.
  • the tube 14 which is biased downwards against the plunger 18 at the seal 19 also moves down with the plunger until the tube 14 engages with the sleeve 22 via the seal 23.
  • the biasing force from the bellows 16 and the spring 17 ensures that the seals at 8 and 23 are tight. The inside of the bottle is then completely isolated.
  • the valve is closed by withdrawing the plunger 18 upwards so that the initial position is regained.
  • the amount of milk filled into the bottle is determined by the capacity of the bottle minus the displacement of the plunger in its downward or filling position.

  • the apparatus illustrated in FIGURE 3 differs from that shown in FIGURE 2 in that it will not allow filling when a bottle is not present in the container 2a. This modification is accomplished primarily by the provision of an additional seal 29 on the outer bevel at the lower end of the sleeve 22a. This seal 29 is adapted to engage with the mouth of the bottle 1a when the sleeve 22a is moved downwards.
  • the seal 80 which seals the mouth of the bottle 1a against the housing 26a only seals with the other portion of the top surface of the lip, thereby leaving the inner portion free to seal with seal 29.
