Definitions

  • the present invention relates to a method of, and a device for introducing an amount of liquid into a package by means of a filling , method according to the preamble of claim 1 and a filling device according to the preamble of claim 8.
  • Introducing a liquid into a package is generally known in the art.
  • the most well known application is of course packaging a liquid, wherein the package is filled with liquid.
  • Another application is adding liquid to a package for another product.
  • sauce may for example be added to a foodstuff.
  • Water may also be added to a fresh product, such as carrots.
  • the package may also be a container having an edge on top of which a film is applied for closing the package.
  • liquid may lead to liquid ending up at the outside of the package, which may be undesired from the perspective of hygiene or rejection by the consumer. It is also problematic when the presence of the liquid results in unsuccesful closing of the package or in a weakened sealing such as a seal, causing its leakage and/or causing the contents of the package to have a shorter shelf life.
  • a method according to the preamble is known from DE-A-102015204951 or from US 2019 077 648 A1 .
  • the present invention aims to provide a method by means of which a measured amount of liquid may be dispensed with a smaller chance of leakage of the liquid.
  • the method according to claim 1 is characterized in that the cylinder is a first cylinder and the filling device comprises a second cylinder, which second cylinder comprises a second piston and a second chamber, wherein the second chamber is equipped with
  • Sucking back liquid from the filling lance, and more specifically from the mouth piece of the filling lance in the direction of the chamber, may be achieved very effectively.
  • the inlet valve of the chamber is closed during the first stage, whereby sucking back liquid into the mouth piece may be assured more effectively.
  • the chance of leakage of the liquid from the filling lance is reduced and therefor also the chance of aforementioned problems which may be associated with it.
  • the liquid is for example sucked back over a distane of at least 0.5 cm, preferably over at least 2 cm.
  • a relatively runny liquid such as water
  • a relatively viscous liquid such as a sauce
  • a branch pipe may be placed between the chamber and the mouth piece, which is provided with a device for discharging liquid, such as a powered vacuum pump.
  • the step of sucking back comprises sucking liquid at least partially back in the filling lance to the chamber.
  • the chamber may effectively be used for storing sucked back liquid.
  • the step of introducing a measured amount of the liquid into the package using the filling device comprises introducing the mouth piece of the filling lance into the package by a relative movement of the package and the mouth piece, and between the step of introducing a measured amount of the liquid into the package using the filling device and the step of closing the package after removing the mouth piece of the filling lance from the package, the distal end of the filling lance is removed from the package by a relative movement of the package and the mouth piece.
  • liquid may effectively be introduced into the package such as a bottle or a bag while the chance of a problem due to dripping is reduced.
  • the filling lance is provided with a further valve at a distance of less than 20 cm from the mouth piece, which further valve
  • the distance of the third valve to the mouth piece is preferably less than 30 cm, more preferably less than 15 cm and most preferably less than 7 cm.
  • the further valve is closed during the entire second stage.
  • the filling lance provides a third valve and the liquid flow may be blocked or enabled by the chamber wall by moving the chamber wall and the section with respect to each other.
  • the first section is kept stationary independent of the position.
  • controled valves are diaphragm valves.
  • Diaphragm valves may be opened and closed quickly, which contributes to a precise dispension and preventing leakage.
  • the present invention relates to a filling device for introducing an amount of liquid into a package, according to claim 8.
  • Such a filling device allows to provide twice as many packages with liquid using a single filling lance.
  • the chance of leaking of the liquid from the filling lance is reduced and thereby also the chance of the aforementioned problems which may be associated with it.
  • a relatively runny liquid such as water
  • a relatively viscous liquid such as a sauce
  • a branch pipe may be present between the chamber and the mouth piece, which is provided with or connectable to a device for discharging liquid, such as a vacuum pump.
  • the filling lance is provided with a further controlled valve at a distance of less than 20 cm from the mouth piece.
  • the distance from the third valve to the mouth piece is preferably less than 30 cm, more preferably less than 15 cm and most preferably less than 7 cm.
  • the filling lance provides a third valve and the liquid flux through the dispense chamber may be blocked or enabled by moving the chamber wall and the section with respect to each other.
  • the controlled valves are diaphragm valves.
  • Diaphragm valves may be opened and closed quickly, which contributes to a precise dispension and preventing leakage.
  • Fig. 1A en Fig. 1B show perspective views on part of a filling device 100, wherein filling lance 200 ( Fig. 2 ) is omitted.

  • the cylinders 110 comprise a piston, wherein a piston rod 111 is driven by a servomotor 181 in motor housing 180 having a drive axis 182, which is connected to a crankshaft 183 which may move the piston rod 111 through a drive rod 184.
  • the servomotor drives the cankshaft 183 to perform a back and forth going motion, wherein an extreme is determined by a stop 84.
  • Fig. 1B one motor housing 180 is omitted.
  • the filling device 100 comprises for each cylinder 110 a controlled inlet valve 130 and a controlled outlet valve 140, in the form of pneumatically drivable diaphragm valves. These diaphragm valves are provided with air inlets which may be connected to a pneumatic control unit 150 housed in lid 101. Air hoses are omitted for clarity.
  • the pneumatically drivable diaphragm valves are in themselves known.
  • the filling lance 200 comprises a first section 210 and a second section 220 which are movable with respect to each other in axial direction.
  • the first section 210 comprises a mouth piece 201 at a distal end.
  • the second section 220 comprises a proximal end 202 for connection to the dispense opening 191. Liquid dispensed by the cylinders 110 liquid flows through the dispense channel 190, through the second section 220, through the first section 210 to the mouth piece 201 where the liquid is dispensed by the filling lance 200.
  • the filling lance 200 comprises a further valve 230. This is formed by a proximal part of the first section 210 and a distal part of the second section 220, as will be explained by means of Fig. 3 .
  • the first section 210 is not moved while filling and the second section 220 may move with respect to the first section 210 in axial direction by an actuator 250, and a lever arm 255 which is hingedly attached to the second section 220.
  • Fig. 3A and Fig. 3B show longitudinal cross sections through an end of the filling lance 200 of Fig. 2 .
  • Fig. 3A shows the further valve 230 in an opened state and

  • the chamber wall 321 is fixedly connected to the second section 220.
  • the first section 210 and the second section 220 are in axial direction relatively moveable with respect to each other between i) a first position in which the through hole 311 of the first section 210 is closed by the chamber wall of the distal end of the second section 220 ( Fig. 3B ) and the sealing ring 313 seals against the second section 220 and ii) a second position in which the through hole 311 of the first section is located at least partially in the dispense chamber 320 and is in liquid connection with the proximal end of the second section 220.
  • Fig. 4A to Fig. 4G show diagrams illustrating the method according to the invention for the filling device 100 of Fig. 1 .
