Description

The invention relates to a method for producing and / or filling a package for flowable, in particular liquid and viscous, products. Furthermore, the invention relates to a device for carrying out a corresponding method.

With an outer packaging in the context of the present invention, a relatively stiff compared to the flexible inner bag material or element is meant, which is suitable to keep the inner bag in an upright position permanently. Such outer packages are usually formed by a cardboard casing, which usually has a cuboid shape. In principle, a relatively rigid plastic can be used.

A typical package of the type previously described, with a flexible inner bag and a relatively rigid carton as the overwrap, is the so-called "bag-in-box" package, which has been known as a liquid container since the 1950's. The inner bag is made of a flexible film composite material that is mechanically supported by a corrugated cardboard or the like. The inner bag is usually filled with a non-pressurized liquid, such as a drink, and closed at one end via a spout having a spout. The so filled and closed inner bag is then inserted into the outer packaging. The carton forming the outer packaging is then completely closed.

The problem with the preceding pack is the relatively complicated operation for the consumer. For example, the consumer first has to provide an opening in the outer packaging by pressing in a usually pre-cut window in the cardboard material. Then the consumer has to grab the tap inside the box and lead it out through the previously made opening. Afterwards the packing must be aligned so that the liquid can flow out automatically when opening the tap. Only then can the consumer open the tap and remove the liquid. The tap is always mounted at the bottom to allow liquid leakage by means of the static pressure and the collapsing bag inside, which is cumbersome when using a pack of several liters, for example 20 liters.

Such a pack has not yet prevailed in the private consumer, but is mainly used in the catering industry. This is certainly due firstly to the fact that the end user is accustomed to consuming liquids from plastic or glass bottles in which he only has to loosen a screw cap, bottle cap or cork and can then immediately pour out the liquid by tilting the bottle. In comparison, the use of a bag-in-box system is relatively complex. On the other hand, the bag-in-box system has the disadvantage that a tap, albeit only to a small extent, accumulates drops, which has undesirable contamination in the consumer household result. Also, the liquid is always under pressure at the tap so that it can drain when the tap is open, so that in the event that the tap is inadvertently not completely closed, liquid can escape from the pack, which further increases the risk of contamination of the environment (risk of leakage).

In the catering industry, the above disadvantages are less relevant, since they are often large packs of several liters, usually up to 20 liters, which are long enough and do not need to be changed so often. In gastronomy, these packs are usually in the taproom or in the kitchen, which areas are cleaned daily anyway and are also easier to keep clean due to special functional surfaces than in the case of a private household.

Against this background, there is therefore a need on the part of the beverage industry to develop beverage packs and the like which, on the one hand, are relatively easy to use and thus more easily accepted by the end user. On the other hand, there is a trend towards environmentally friendly and resource-saving materials. Finally, it is also desirable if the emptied pack occupies as small a volume as possible, which facilitates the disposal and easy separation of plastic and cardboard.

Also known from the prior art are plastic bags as packages for liquids, which have two opposite side walls of a relatively rigid plastic and two orthogonal side walls made of a relatively flexible plastic and are provided on their upper side with a spout having a closure cap. On the one hand, these packs are easy to use and, on the other hand, because they are made of recyclable plastic, they are environmentally friendly and resource-saving. Also, these packages can be folded in the emptied state to a relatively small volume. Due to the use of different stiff plastics but the production of the packages is relatively expensive. Also, compared to carton packs, the packs have a relatively unstable state and therefore can not be made arbitrarily large, especially as far as the height is concerned.

It is an object of the present invention to provide a method and an apparatus for producing and / or filling a package for flowable products, whereby a package can be produced in the simplest possible way, which satisfies the foregoing requirements.

The previously derived and indicated object is achieved according to a first teaching of the present invention by a process for producing and / or filling a package for flowable, in particular liquid and viscous, products comprising:

• A step of providing a film in a tubular bag machine,
• A step of providing a plurality of spouts,
• A step of providing a plurality of material blanks having an opening,
• A step of peeling the film in a direction of production movement,
• A step of introducing openings in the film at regular intervals in the direction of production movement,
• A step of inserting one of the spouts into each of the openings of the film,
• A step of forming the film into a tube,
• A step of longitudinal sealing of the film in the direction of production movement,
• A step of transversely sealing the film at regular intervals in the direction of production movement,
• A step of separating individual film sections at regular intervals in the production movement direction, whereby bags are separated,
• A step of filling the bags with the product,
• A step of welding the bags in the headspace
• A step of erecting the individual material blanks and forming an outer packaging,
• A step of inserting one of the bags into one of the outer packages, wherein the respective spout is guided through the opening of the outer package to the outside, and
• - A step of generating a, in particular releasable, connection between spout and outer packaging.

The foregoing steps are not limited to a particular order, but may be performed at least in part in almost any order.

For example, however, the steps can also be carried out in the order in which they were used in the preceding list of the method steps according to the invention.

With such a method, a packing for flowable products, for example a beverage pack, can be produced in a particularly simple manner, since the individual method steps are selected and coordinated so that the method can be carried out at least predominantly, preferably completely, in an automated manner. At the same time, this method makes it possible for the pack produced thereby on the one hand to be particularly easy for a consumer to use, but on the other hand it is also environmentally friendly and resource-saving. A flowable product package made in this manner may also be put into a relatively small volume after emptying, especially if the outer packaging is previously separated from the inner bag, which is relatively simple since the bag and outer packaging are not interconnected except for the entanglement and / or concealment of the spout with the edges of the opening in the outer packaging.

In the following, some embodiments of the method according to the invention will now be described.

According to one embodiment of the method according to the invention, the spout with pre-assembled closure, in particular preassembled closure cap, which may be a screw cap, is inserted into the opening of the film. But it is also possible to use the spout first without closure and the closure only in a later process step, for example, after filling set up.

The openings of the film are produced by a separate tool according to another embodiment of the method according to the invention. Separately means that not the spout itself is used to create the openings, but this happens on the machine side. Of course, but also the spout may be formed so that it is adapted to produce even the respective opening. The openings for inserting the spout are in particular punched.

As already indicated above, the individual process steps can be carried out in different orders, sometimes also simultaneously.

Thus, it is preferred if the respective spout is inserted into the respective opening of the film before the step of forming the film into a tube. In principle, however, it is also conceivable to carry out the step of insertion after the shaping of the film.

It is also preferable to insert the respective spout prior to the longitudinal sealing and / or transversal sealing step, although this may be done afterwards.

According to a further embodiment of the method according to the invention, the spout is fixed to the film, d. H. insoluble, connected. Insoluble means that the connection can not be easily solved by the consumer without applying an increased force. In particular, the spouts are connected to the film immediately after the step of inserting the spouts into the openings of the film. In principle, however, the connection could also be made later.

The connections described above, that is, the connection of the spout to the film and / or the longitudinal and / or transverse seals and / or the welding in the head space, are carried out according to a further embodiment of the method by means of ultrasound. In principle, a heat-sealing with in particular permanently heated sealing jaws is conceivable. Preferably, however, should be dispensed with a separate adhesive for the preparation of the compounds, which simplifies the process, makes it faster, more environmentally friendly and makes the individual packaging easier recyclable.

In the step of transversely sealing the film, in each case a double seam is produced according to a further embodiment of the method according to the invention and the separation of individual film sections is effected by a separating cut between the seams of the double seam. In principle, however, it is also conceivable to provide a relatively wide transverse sealing with only one seam, in which case the severing cut is made through the seam such that a part of the seam is arranged on both sides of the separating cut.

According to yet another embodiment of the method according to the invention, it is provided that the step of forming the film into a tube takes place via a forming shoulder, which is in particular tubular, wherein preferably the step of filling the bag takes place via a filling tube arranged in the interior of the forming shoulder. The filling is basically possible later, for example, after the insertion of the bag in the outer packaging. When filling, preferably 0.2-2 l of the product, preferably 0.25-1.5 l of the product, is filled into the bag.

According to another embodiment of the method according to the invention, before the step of welding the bags in the head space and after the step of filling the bags with the product, the head space is evacuated, which takes place automatically in particular. As a result, upon first opening the package and the bag, air first flows into the headspace of the bag, preventing any part of the product from inadvertently spilling over when the package is opened.

The filled and closed bag is gripped according to a further embodiment of the spout and / or on the closure and is in particular passed to a transfer system. The transfer system can be equipped with special rails, for example C rails, which engage in a groove provided on the spout.

According to yet another embodiment of the method according to the invention, the filled and closed bag, in particular from the transfer system, is inserted into the outer packaging. In principle, it is also conceivable that the unfilled bag is first inserted into the outer packaging and only then filled.

According to yet another embodiment of the method according to the invention, the outer packaging is closed after insertion of the bag with a lid. In principle, but also outer packaging are conceivable that do not have to be closed, since they consist for example of an annular strip, such as annular cardboard strips, which forms an inevitably open on both sides outer packaging, so that the bag can also be inserted from the side into the outer packaging.

Regardless of the form of the outer packaging, it is provided according to a further embodiment of the method according to the invention that the step of generating the, in particular detachable, connection between spout and outer packaging comprises generating a punctiform connection. The connection, in particular the punctiform connection, as well as the other connections can be made by means of ultrasound. In principle, a heat sealing with, in particular, permanently heated sealing jaws is also conceivable here. In any case, should be dispensed as possible with this connection as possible to an adhesive.

Furthermore, the material used for the individual elements forming the pack should briefly be discussed. Thus, the film and / or the spout is preferably made of plastic and / or the material blank preferably made of cardboard.

According to one embodiment of the method according to the invention this is performed clocked. Several of the previously described steps can also be performed simultaneously. But it is also conceivable that the process is carried out continuously.

According to a second teaching of the present invention, the object is also achieved by a device for carrying out the method, as has been described above.

An example of a typical package for flowable, in particular liquid and viscous, products, as can be produced by the method according to the invention and / or by the device according to the invention will now be described below.

Thus, the production or the filling of a package is conceivable with a flexible inner bag for receiving a product, wherein the inner bag is provided with a shutter having a spout, and with an outer package which partially or completely surrounds the inner bag and supports the inner bag, wherein the outer packaging has an opening through which the spout is guided to the outside, wherein the spout is connected to the outer packaging, in particular detachably connected.

By a releasable connection is meant such a connection which is easily detachable from the consumer by hand, that is without much effort and without the use of tools. The connection between spout and outer packaging is therefore preferably just so strong that in a proper loosening or unscrewing (or placing or screwing) of the cap and in a proper use of the package in the event that the product is to be removed, the Compound holds, but as soon as a greater relative force between spout and outer packaging is spent, as is necessary for the intended use, the outer packaging immediately dissolves from the spout with the bag. The latter can be favored, for example, by the lid of the outer packaging is unfolded or released from the remaining part of the outer packaging.

According to one embodiment of the package according to the invention, the outer packaging has a bottom, a plurality of side walls, preferably four side walls, and a lid, wherein the opening is provided in the lid and the spout is connected to the lid, in particular detachably. Such outer packaging is particularly stable, visually appealing and easy to use by the user. Also, such a package is optimal, even in large quantities, storable.

According to a further embodiment of the packing according to the invention it is provided that the spout has a radially outwardly projecting flange and a radially outwardly projecting collar, wherein the flange and the collar are spaced apart in the axial direction, the distance in particular less than 4 mm, preferably less than 2 mm, more preferably less than 1.5 mm. The flange and / or the collar can be formed by a circumferential ring or by a plurality of circumferentially arranged tabs. The flange, which can be arranged at the bottom, directed towards the inner bag end of the spout, serves to secure the inner bag to the spout. Preferably, the spout is guided from the inside through an opening in the bag to the outside, wherein the flange comes to rest on the inside of the bag. The film of the inner bag and the flange are then connected to each other inseparably, for example by heat sealing with, in particular, permanently heated sealing jaws or ultrasonic welding. The collar, which is spaced in the direction of pointing away from the inner bag end of the spout from the flange, serves as an attachment for the outer packaging, in particular the lid. It is preferably provided that the spout is guided through an opening in the inner bag to the outside, wherein a portion of the outer packaging, in particular the lid, and a portion of the inner bag between the flange and the collar arranged, in particular jammed, are.

In this case, the portion of the outer packaging, in particular of the lid, have incisions which point to the opening of the outer packaging and in particular are directed radially to the center of the opening. The length of the incisions corresponds at least to the radial extent of the collar, so that the lid or the outer packaging can be simply slipped over the collar, in particular in the manufacture of the package, when the opening part of the outer packaging, such as the lid, with the Spout and the collar is connected. Equally, however, this also applies to the case that in an example emptied pack of the opening having part of the outer packaging or the lid is opened or removed from the spout to separate the inner bag of the outer packaging.

As already indicated above, according to one embodiment, the side of the flange facing the collar is connected in a liquid-tight manner to the inner bag. The flange is preferably located on the inside of the inner surface of the inner bag. The flange-facing side of the collar is, as already indicated, preferably connected to the outer packaging, in particular the lid, so that, from inside to outside, an exemplary layer structure results, starting with the flange, followed by a portion of the inner bag ( that is the film of the inner bag), again followed by a portion of the outer package or the lid and finally ending with the collar.

In order to achieve a permanent and yet easily detachable connection between spout and outer packaging, it can be provided that the connection between the collar and outer packaging, in particular cover, is a punctiform connection, which is preferably formed by sealing points, particularly preferably ultrasonic welding points , By providing sealing points or ultrasonic welding spots, it is possible to dispense with adhesive, since in the sealing area the plastic of the collar and / or the surface or coating of the outer packaging is locally heated and fused, resulting in a permanent and adhesive-free connection between collar and outer packaging , In particular, the outer packaging, at least in the region of the connection to the collar, is provided with a surface, in particular a coating, which is configured to form an adhesive bond with heated (ie liquefied) plastic after it has hardened. In principle, however, it is also conceivable to produce the connection between spout and outer packaging by means of glue, in particular hot glue. So it is here, especially in a only selective connection to a relatively small area, it must be connected, so that, in particular if the outer packaging is made adhesive-free, characterized the package can still be produced environmentally friendly and cost-effective.

According to a further embodiment, the flange has a larger diameter than the collar, wherein the flange in a portion which is covered in the axial direction by the collar, has a greater thickness than in the remaining part. In this way, on the one hand, the insertion of the (cardboard) material of the outer packaging in the region between the flange and collar is facilitated because the outer part of the flange behaves flexibly and elastically. The inner part of the flange, which is covered in the axial direction by the collar, however, is stiffer and favors jamming of the material of the outer packaging between flange and collar.

According to yet another embodiment of the package according to the invention as described above it is possible (but not mandatory) to make at least the connection between spout and outer packaging adhesive-free, that is for the connection no glue, in particular hot glue, is used in the case. It is additionally or alternatively also conceivable to join the outer packaging free of adhesive, for example by heat sealing with in particular permanently heated sealing jaws or preferably by ultrasonic welding. Such adhesive-free packing is on the one hand particularly environmentally friendly, on the other hand, but also relatively inexpensive to manufacture. Also, a corresponding manufacturing device, since an adhesive is dispensable, be simpler structure.

The inner bag is connected according to still another embodiment of the package according to the invention only on the spout with the outer packaging and movable in the outer packaging. In other words, the inner bag is fixed only on the spout, but not on the outer packaging. In this way, when emptying the package, that is, for example when a liquid is flowing out, the inner bag can correspondingly reduce its volume around the part of the product which has run off. In other words, the inner bag thus correspondingly (collapses) when pouring out the product, which has the advantage that no pressure equalization must take place in the inner bag during pouring, ie no air flows in during the pouring process from the outside. The latter results in non-yielding (collapsing) packs to a jerky outflow (pülschen) of the product, which is successfully avoided according to the invention. Furthermore, by filling the bag with an air-free head space, it is also possible to reliably prevent the liquid from spilling over when the package is opened for the first time since air then flows in first.

The outer packaging, the spout and the inner bag can be made of different materials, as long as it is ensured that the inner bag is flexible and in the package during emptying as free to move as possible, that is collapse, and as long as the outer packaging of the flexible inner bag by a relative to Inner bag supports stiffer material and preferably also protects to all sides. From an environmental point of view, it is particularly recommendable if the outer packaging largely, preferably completely, consists of cardboard. The inner bag and / or the spout can largely, preferably completely, be made of plastic.

According to a further embodiment of the package according to the invention extends at least a portion of the lid, preferably the complete lid, obliquely to the bottom and / or at least one of the side walls of the pack. Such an oblique course facilitates the pouring of the product, since in this way the spout, in particular when it is connected to a protruding perpendicular to the central axis of the spout collar with the surface of the lid, is set correspondingly inclined. However, it is also conceivable, independently of the course of the cover, that the central axis of the spout runs obliquely to the bottom and / or at least one of the side walls. The angle between the oblique plane, in which said oblique lid portion or the lid extends, and the plane in which said bottom extends is, for example, 10 to 45 °, preferably 15 to 38 °, especially preferably 20 to 25 °. The angle between the central axis of the spout and the plane through which the bottom passes is, for example, 45 to 80 °, preferably 52 to 75 °, particularly preferably 65 to 70 °. In principle, however, a rectangular instead of an oblique course is conceivable, that is, the lid is parallel and / or the central axis of the spout perpendicular to the ground.

In order to ensure a secure and stable connection between spout and outer packaging is provided according to a further embodiment of the package according to the invention that the wall of the spout in the region between the flange and collar has an enlarged cross-section. Such an enlarged cross-section, which is thus greater than the remaining cross section of the wall of the spout, increases the rigidity of the spout in the region with which it is attached to the outer packaging. Also, this is the area in which the outer packaging attached to the spout together with the inner bag, in particular jammed, can be, so that the clamping force does not wear off over time.

According to yet another embodiment, it is provided that at least one of the side walls, preferably all side walls, have tabs at their end facing the lid, which engage with tabs provided on the lid in the closed state of the lid, in particular each tab of the side walls a tab of Lid and / or each tab of the lid is associated with a tab of the side walls. In this way, the lid, which may be a hinged lid, can be easily connected to the side walls, which in turn benefits the stability of the entire package. Hooking tabs also have the advantage that, on the one hand, no adhesive must be used for the connection between the lid and the side walls and, on the other hand, an additional step of gluing or sealing may be dispensed with in the manufacture of the pack.

The hooking described above can be realized in a particularly simple manner if, according to a further embodiment of the package according to the invention, the outer packaging consists of a one-piece blank. An integral blank also minimizes the number of points at which two adjacent sections of the outer package must be joined together, for example by ultrasonic welding.

There are now a large number of possibilities for designing and developing the method according to the invention and the device according to the invention. For this purpose, reference is made, on the one hand, to the claims subordinate to patent claim 1, and, on the other hand, to the description of exemplary embodiments in conjunction with the drawing. In the drawing shows:

1 a schematic flow diagram of an embodiment of the method according to the invention and

2 an embodiment of a pack, with the in 1 has been prepared.

At the in 1 shown method, which represents only one embodiment, the following method steps are carried out successively in the order given:
S1: providing a film in a tubular bag machine,
S2: Provide a variety of spouts 2 .
S3: providing a plurality of material blanks having an opening,
S4: peeling the film in a production movement direction,
S5: introducing openings into the film at regular intervals in the direction of production movement,
S6: Inserting one of the spouts 2 in each case one of the openings of the film,
S7: forming the film into a tube,
S8: longitudinal sealing of the film in the direction of production movement,
S9: transversely sealing the film at regular intervals in the direction of production movement,
S10: Separation of individual film sections at regular intervals in the production movement direction, whereby bags 3 to be isolated
S11: filling the bags 3 with the product,
S12: Welding the bags 3 in the headspace 4 .
S13: Erection of the individual material blanks and forms of an outer packaging 5 .
S14: Inserting one of the bags 3 in each case one of the outer packaging 5 , wherein the respective spouts 2 through the opening of the outer packaging 5 is led to the outside, and
S15: creating a releasable connection between spouts 2 and outer packaging 5 ,

More specifically, in the method according to the invention, for example, first a roll of a suitable film is hung in a tubular bag machine. The film is peeled off in the direction of production movement, and a matching hole or hole is made to fit, suitable for pushing through the spout 2 , punched. A spout 2 , consisting of a lower part with flange and pre-assembled screw cap 6 , is sorted, supplied and inserted through the hole or the opening in the film. With ultrasound, the flange of this spout 2 connected to the inside of the film. About a tubular form shoulder of the tubular bag machine, a tube is made of the film. The film is longitudinally sealed by ultrasound. A transverse seal at the end of this hose is made with a double seam, wherein in the middle between the two seams of the double seam with a cutting knife a separating cut is performed. The transverse sealing is done by means of ultrasound. Inside this tube and the tube of the forming shoulder is a smaller filling tube to deliver the desired amount of liquid. After the liquid is filled, the headspace becomes 4 in the area of the spout 2 vacuum before performing a horizontal weld.

The bag made in this way 3 falls out of the device and gets to the top of the spout 2 especially on his cap 6 , gripped and in one on the neck of the spout 2 pass existing guide groove in a transfer system. At the end of the transfer is filled with, for example, 0.25-1.5 l bag 3 in a box 5 introduced.

Parallel to the power stroke of the flow wrapper, a carton blank made from a recycled fiber material is erected. The carton blank is provided with a varnish which allows bonding by means of ultrasonic welding, which eliminates the classic bonding with hot glue. The top open box 5 gets to the transfer point of the flexible bag 3 transported where the bag 3 in the outer carton 5 is lowered.

The spout cap 6 gets through the round pouring punching of the carton 5 pushed, with the cardboard punched with the collar of the spout 2 hooked. An ultrasonic seal connects the collar of the spout 2 with the paint of the box 5 , Finally, there are three special tabs with hooking possibilities inside the carton 5 folded by 45 ° and thus close the carton 5 , The flap-shaped lid 7 shows the consumer the plastic cap 6 through which he gets the contents of this pack 1 can consume.

A typical pack 1 as prepared by the method described above 2 , The package 1 has a flexible inner bag 3 for receiving the product and a cuboid-like outer packaging 5 on that the inner bag 3 completely surrounds, supporting and protecting him. The inner bag 3 is in the headspace 4 with a one cap 6 having spouts 2 Mistake. The outer packaging 5 has an opening through which the spout 2 led to the outside. The spout 2 is with the outer packaging 5 releasably connected, so when emptied pack 1 without further ado the lid 7 the outer packaging 5 opened and the spout 2 from the lid 7 and thus the entire inner bag 3 from the entire outer packaging 5 can be separated.

Finally, it should be emphasized that in a pack 1 obtained by the method according to the invention, for example the method described in 1 illustrated method, is basically also conceivable, if that of the inner bag 3 and / or the outer packaging 5 with an adhesive to the spout 2 get connected.
