Definitions

  • the present invention relates to a method of aseptically filling a container with a fluid in which the outlet nozzle of a fluid dispenser is brought into abutment with the inlet of the container, the container is filled with the fluid, the container is sealed, and is then removed from the dispenser.
  • Synthetic plastics flexible containers are useful for storing and dispensing wine, fruit juice and other liquid foodstuffs. Aseptic filling is a desirable mode of operation to ensure that the possibility of contamination or deterioration of the liquid product does not occur.
  • aseptic filling is carried out by sterilising the flexible containers internally and externally and maintaining the filling equipment in a sterile room. It is very difficult to ensure that the equipment and containers are maintained in aseptic conditions and the time and expense involved is high.
  • a method of aseptically filling containers is characterised by sterilising the container, the container inlet being covered by a rupturable closure, maintaining the internal surfaces of the dispenser in a sterile state; sterilising the surfaces of, and space between, the said nozzle and the inlet; and subsequently breaking the rupturable closure prior to filling the container.
  • a system for aseptically filling a container with a degradable liquid for storage comprising a flexible container having an inlet, a fluid dispenser having a filling head with an internally disposed valve member for regulating flow of the liquid, a container support arranged to bring the container into engagement with the filling head, means to actuate the valve member to allow liquid to pass into the container, and means to seal the inlet characterised by a rupturable clo-sure over the inlet a recess between the valve member and the closure when the inlet is in engagement with the filling head, a sterilising fluid inlet and outlet in the recess, means to supply sterilising fluid to the recess and means to remove the sterilising fluid from the recess, radiation means for sterilising the container while closed by the closure, and means for rupturing the closure to allow the container to be filled.
  • the filling apparatus of this invention incorporates a filling nozzle in which the liquid outlet valve is located away from the outlet to form a recess communicating with which is an inlet for a sterilizing fluid and an outlet for said sterilizing fluid.
  • the inlet and outlet within the nozzle recess may be the same in which case the conduit from said inlet/outlet port is connected to a source of sterilizing fluid and an extractor.for withdrawing said fluid from the nozzle recess.
  • Gamma radiation is used to sterilize the sealed containers prior to filling and hydrogen peroxide or steam is used to sterilize the surfaces and space between the outlet nozzle and the container clo- sure.
  • figure 1 is a schematic view of the container and collar
  • figure 2 is a sectional view of the filling nozzle
  • figure 3 is a cross-section through the head during the filling cycle
  • figure 4 is a cross-section showing the sealing operation while the container is still in position at the filling head.
  • the bag - generally designated as 1 - comprises a wall 2 heat sealed at the periphery 3 to the lower wall 4.
  • the flap 5 extends across an opening 7 in the flexible container wall 2 into which fits a collar 8.
  • the flange 9 of collar 8 is heat sealed to the periphery 10 of the opening and the flap 5 is partly sealed to the flange of collar 8.
  • the collar 8 can easily be secured to wall 2 by suitable machinery.
  • the surface of flap 5 which faces the internal surface of wall 4 is non heat sealable therewith but the surface of flap 5 which faces flange 9 is heat sealable with that flange.
  • flap 5 is a laminate of a heat sealable and a non heat sealable material.
  • a rupturable membrane 41 which is either integrally formed during the moulding of.collar 8 or is heat sealed thereto during the operation of attaching the collar 8 to the container wall 2.
  • the container and collar is as described in European patent publication no. 0 007685 Al.
  • the filling apparatus is a modified version of that described in European patent application 82 300 1 458.
  • the filling head comprises a general body section 20 which includes a liquid inlet channel 21 closed by the valve member 22.
  • This valve member 22 extends within the body section 20, and includes evacuation port 24 which is connected to a vacuum line 25.
  • the vacuum port 24 is closed by the seal 26 and the valve stem 27 which reciprocates within the valve member 22.
  • the sterilizing fluid inlet 44 and outlet 45 are connected to the nozzle recess 46 below the valve member 22.
  • FIG 3 the complete flexible container is illustrated being held against the body section 20 by clamps 33.
  • clamps 33 grip the collar 8 and a trapdoor 36 supports the flexible container but provides a sufficient gap to enable liquid to flow through collar 8 past flap 5 and into the body of the flexible container 1.
  • the support of trapdoor 36 is required to ensure that the pressure of the liquid during the filling does not rupture the container.
  • the sequence of operations is that initially a flexible container 1, is taken by clamps 33 and lifted into alignment with the filling head such that collar 8 and membrane 41 abut tightly against the seal 31 on the body section 20. After contact is made between body section 20 and membrane 41 sterilizing fluid (either gas or liquid) is passed in to the recess 46 via inlet 44 and sterilizes the inner surfaces of the recess and the surface of membrane 41. Subsequently the sterilizing fluid is withdrawn through outlet 45.
  • sterilizing fluid either gas or liquid
  • Another variation of this invention is to eliminate outlet 45 and either use the vacuum outlet 25 to remove sterilizing fluid or to extract it through the inlet.44.
  • valve member 22 rises to open the liquid inlet 21 to enable filling of the flexible container to occur.
  • the membrane 41 is ruptured during filling by the pressure of the liquid and is subsequently not needed since flap 5 will provide the permanent seal for the filled container.
  • the membrane 41 may be ruptured by valve stem 27 prior to the opening of liquid inlet 21.
  • valve member Upon the completion of filling the valve member closes inlet 21 and the valve stem 27 enters collar 8. This ensures that all liquid in the collar 8 is displaced into the flexible container. At this point the trapdoor 36 is withdrawn and the heat sealing member 35 is brought into contact with the flexible container and results in the welding of flap 5 to the flange 9 of the collar 8 to seal the flexible container. Subsequent to sealing the filled flexible container is withdrawn from the filling head and if desired the tap can be inserted into collar 8.
  • Conventional pneumatics can be used to operate the movements of the various valves 22 and 27 and the clamps 33, the trapdoor 36 and sealing member 35.
  • the timing and control of these components is similarly capable of being carried out by conventional control circuitry.
  • this invention provides a simple means of ensuring aseptic filling of liquids.
