Abstract
Description
- The present invention relates to a method of introducing an amount of liquid into a package by means of a filling device, which filling device
- comprises a chamber for liquid,
- comprises a filling lance connected to the chamber, which filling lance comprises a mouth piece at a distal end thereof for dispensing liquid from the chamber;
- introducing a measured amount of the liquid into the package using the filling device, and
- closing the package after introducing the liquid into the package using the filling lance.
- 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. In this way sauce may for example be added to a foodstuff. It is also possible to form the package simultaneous with or immediately prior to filling, such as a film package which is to be formed by means of sealing a film sheet. 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.
- Introducing the 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
DE102015204951 . - 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.
- To this end, method according to the preamble is characterized in that
- after introducing the liquid into the package, and
- without the mouth piece extending into the liquid which is introduced into the package;
- In this way 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) will be sucked back over a relatively large distance, while a relatively viscous liquid such as a sauce may be sucked back over a relatively short distance.
- For sucking back, 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.
-
US2019/077648 describes a valve assembly for filling containers and the dripping occuring therein. - According to a favourable embodiment, 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.
- According to a favourable embodiment, 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. - In this way 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.
- According to a favourable embodiment, the filling device comprises a cylinder, which cylinder comprises a piston and the chamber, wherein the cylinder is fitted with
- a controlled inlet valve, and
- a controlled outlet valve between the chamber and the filling lance;
- in a first step the piston is moved in a first direction for discharging liquid through the controlled outlet valve from the chamber, to the filling lance, wherein the inlet valve of the chamber is closed and the outlet valve is opened, and
- in a second step after the first step the piston is moved in a second direction opposite to the first direction for supplying liquid to the chamber through the supply valve, wherein in a first stage of the second step at least the outlet valve is opened for sucking back liquid from the filling lance, and in a second stage of this second step the outlet valve is closed and the inlet valve is opened.
- In this way 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. Advantageously 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.
- According to a favourable embodiment, the filling lance is provided with a further valve at a distance of less than 20 cm from the mouth piece, which further valve
- is opened during the first step, and
- is opened during the first stage of the second step and is closed during at least part of the second stage of the second step.
- In this way leaking of liquid from the filling lance is prevented more effectively, in particular in case of a filling lance having a relatively large own volume. 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.
- Advantageously the further valve is closed during the entire second stage.
- According to a favourable embodiment, the filling lance
- comprises a first section and a second section, wherein
- the first section comprises a distal end comprising the mouth piece,
and - the second section comprises a proximal end in fluid connection with the chamber; and
- the first section comprises a distal end comprising the mouth piece,
- comprises a dispense chamber delimited by a chamber wall, wherein an end of a section chosen from
- the proximal end of the first section, and
- the distal end of the second section
- In this way 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.
- Generally the relative movement will be achieved by an actuator.
- According to a favourable embodiment, the first section is kept stationary independent of the position.
- Not moving the first section in axial direction for opening and closing the further valve reduces the chance of dripping by moving the first section.
- Furthermore the use of a push rod in the second section to the first section and a seal for the push rod by the second section are avoided. Due to the absence of this seal the chance of air entering the liquid through the seal is reduced, which air increases the chance of dripping.
- According to a favourable embodiment, the controled valves are diaphragm valves.
- Diaphragm valves may be opened and closed quickly, which contributes to a precise dispension and preventing leakage.
- According to a favourable embodiment, 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
- a second controlled inlet valve, and
- a second controlled outlet valve between the second chamber and the filling lance;
- In this way twice the number of packages may be provided with liquid using a single filling lance.
- In case of a further valve this will not be closed during the entire second stage of a cylinder.
- Finally, the present invention relates to filling device for introducing an amount of liquid into a package, wherein the filling device
- comprises a chamber for liquid,
- comprises a filling lance connected to the chamber, which filling lance comprises a mouth piece at a distal end thereof for dispensing liquid from the chamber;, wherein the filling device is configured to suck liquid which in use remains in the mouth piece after dispensing the liquid at least partially back into the filling lance.
- In this way 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. It may for example be possible to suck the liquid back over a distance of at least 0.5 cm, preferably at least 2 cm. A relatively runny liquid (such as water) will be sucked back over a relatively large distance, while a relatively viscous liquid such as a sauce may be sucked back over a relatively short distance.
- For sucking back, 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.
- According to a favourable embodiment, the filling device comprises a cylinder, which cylinder comprises a piston and the chamber, wherein the cylinder is equipped with
- a controlled inlet valve, and
- a controlled outlet valve between the chamber and the filling lance;
- in a first step, the piston is movable in a first direction for discharging liquid from the chamber through the controlled outlet valve, to the filling lance, wherein the inlet valve of the chamber is closed and the outlet valve is opened, and - in a second step after the first step, the piston is movable in a second direction opposite to the first direction for supplying liquid to the chamber through the supply valve, wherein in a first stage of the second step at least the outlet valve is opened for sucking back liquid from the filling lance, and in a second stage of the second step the outlet valve is closed and the inlet valve is opened.
- In this way sucking back of liquid from the filling lance, and more in particular from the mouth piece of the filling lance towards the chamber, may be achieved very effectively. Advantageously 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.
- According to a favourable embodiment, the filling lance is provided with a further controlled valve at a distance of less than 20 cm from the mouth piece.
- In this way leaking of liquid from the filling lance is prevented more effectively, in particule in case of a filling lance having a relatively large own volume. 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.
- According to a favourable embodiment, the filling lance
- comprises a first section and a second section, wherein
- the first section comprises a distal end comprising the mouth piece,
and - the second section comprises a proximal end in liquid connection with the chamber; and
- the first section comprises a distal end comprising the mouth piece,
- comprises a dispense chamber delimited by a chamber wall, wherein an end of a section chosen from
- the proximal end of the first section, and
- the distal end of the second section
- In this way 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.
- Generally the relative moment will be obtainable by an actuator.
- According to a favourable embodiment, the controlled valves are diaphragm valves.
- Diaphragm valves may be opened and closed quickly, which contributes to a precise dispension and preventing leakage.
- According to a favourable embodiment, 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
- a second controlled inlet valve, and
- a second controlled outlet valve between the second chamber and the filling lance;
- Such a filling device allows to provide twice as many packages with liquid using a single filling lance.
