Abstract

The invention relates to a method for bottling beverages, a bottled beverage packaging and a system for beverage packaging and filling.

Description

The invention relates to a method for bottling beverages, a bottled beverage packaging and a system for beverage packaging and filling.

The aseptic filling is suitable for long, durable food such as UHT milk, very sugar-intensive and germ-spoiling food that must be stored for a long time and the non-aseptic filling is taken for example. B. for fresh milk or juices, which must be stored refrigerated and have only a short residence time (MHD) on the shelf.

In the previous beverage carton machine one buys the laminated film carton composite (usually still incorporated with aluminum) on the roll. This composite is pulled through a hydrogen peroxide bath and thereby sterilized. Then you blow the hydrogen peroxide with purified air or other gases from the film and forms a beverage carton (tubular bag). This is then filled via the fill level and sealed. This leaves no air in the beverage carton. The valve is then sealed from the outside. In most cases, the composite is pre-cut in such a way that only a thin, easy-to-open foil or aluminum coating will continue to ensure tightness. so that when opening only a part of the composite is torn open or cut through the valve.

In other composite packaging, a preformed beverage carton is delivered flat and machine set up. After being sprayed with hydrogen peroxide, it is blown out again to be filled from above.

After the hydrogen peroxide bath or after spraying, the contents in both systems are filled into the bag in a clean room. In some cases, other sterilants or sterilization mechanisms are used. These foods have a very long shelf life of up to 18 months or more.

In the non-aseptic filling can be filled practically in a free environment, since it is assumed that the contents are consumed within a very short time and thus the development of germs and bacteria does not play a major role in the consumption. Depending on the contents, these foods have a very short shelf life of up to 14 weeks and more.

The object of the present invention is to overcome the disadvantages of the prior art.

• a. Befüllen eines Beutels mit Füllgut, wobei der Beutel vor oder nach dem Befüllen mit einem Schraubverschluss versehen wird, und
• b. Umwickeln des Beutels mit einer steifen Umhüllung oder Einsetzen des Beutels in einen vorgefertigten Behälter, wobei der Schraubverschluss mit der Umhüllung oder dem vorgefertigten Behälter fest verbunden wird.

In a first embodiment, the object underlying the invention is achieved by a method for producing a filled food or beverage package, comprising the following steps:

• a. Filling a bag with contents, the bag being provided with a screw cap before or after filling, and
• b. Wrapping the bag with a stiff wrapper or inserting the bag into a prefabricated container with the screw cap firmly attached to the wrapper or prefabricated container.

For example, finished bags can come out of the machine depending on the requirements of the product. However, these do not have the stability, for example, that the end user would accept this packaging. It is advantageous that the finished molded and filled bag is then wrapped outside of the clean room or after the non-aseptic filling then with a rigid wrapper or inserted into a prefabricated container. In this case, the valve can, for example, by a pre-punching or a mechanism in the wrapper, be jammed or attached by a slider from the outside of the envelope so that the weight of the contents even with the bag open, ¾ full, ½ full and almost at empty bag is firmly attached to the enclosure.

The wrapper, for example, in addition to pretend the consumer a larger content, so that you can set in the choice of inner bag on optimal material utilization, without giving the consumer the feeling to buy a smaller package. So z. B. known from the prior art stand-up pouches that look visually very large and still have very little content. On the other hand, if one were to contrast a surface or content-optimized pouch, the end consumer would be given the feeling that the content-wise smaller package would ultimately be the larger one. Here can be counteracted by the free design of the enclosure free, so that the end user can not be fooled by optimizing the material.

• 1. Das Ventil wird beispielsweise auf ein vorgestanztes Loch in der Beutelhülle, aufgesetzt und verbunden. Dabei hat das Ventil beispielsweise einen durchgängigen Boden, der im Verbindungsbereich eine Sollbruchstelle, die dann durch Drehbewegung beim späteren Erstöffnen geplant herausbricht und den Inhalt frei gibt.
• 2. Nur der Ventilsockel des in Punkt 1 beschriebenen Ventils wird beispielsweise mit der Beutelhülle verbunden und erst nach der Füllung wird der Rest des Ventils mit dem Ventilsockel verbunden. Hier kommt beispielsweise ebenfalls der vorgenannte Aufbrechmechanismus zum Einsatz.
• 3. Der Beutel hat beispielsweise keine Vorstanzung und das Ventil oder auch wieder nur der Sockel wird mit dem Beutel verbunden. Dieses Ventil hat dann beispielsweise einen Aufschneidemechanismus der beim Erstöffnen die Beutelhülle durchschneidet und für den Konsumenten das Füllgut zugänglich macht. Hier könnte beispielsweise ebenfalls lediglich der Sockel verbunden werden und anschließend nach der Füllung der Ausguss und/oder das optionale Ventil aufgesetzt werden.

The screw cap or the valve (hereinafter also referred to as "the valve") can be connected to the bag casing, for example, before filling (three different types are explained exemparically):

• 1. The valve is, for example, on a pre-punched hole in the bag sleeve, placed and connected. In this case, the valve has, for example, a continuous floor in the connection area a predetermined breaking point, which then by Rotary movement breaks out at the later first opening planned and releases the content.
• 2. Only the valve base of the valve described in point 1 is connected, for example, with the bag shell and only after the filling of the rest of the valve is connected to the valve base. Here, for example, also the aforementioned breaking mechanism is used.
• 3. The bag, for example, has no pre-punching and the valve or again only the base is connected to the bag. This valve then has, for example, a slicing mechanism which cuts through the bag casing during initial opening and makes the contents available to the consumer. Here, for example, also only the base could be connected and then placed after filling the spout and / or the optional valve.

Advantage: The valve can be pressure-worked on both sides when fastening with the bag or it could also be welded without additional material.

Disadvantage: The valve must pass through the sterile treatment and one has to take into account the technical possibilities when forming the bag by the machine when placing the valve.

The valve is, for example, also connected to the bag only after filling from the outside.

In this case, for example, a cutting tool or opening mechanism in the valve is needed, because the bag is already filled sterile and must be opened through the spout or the spout with valve. Here, the above-described power transmission through the membrane is particularly advantageous.

Advantage: The valve can be placed practically anywhere and does not have to undergo the complex sterilization process.

Disadvantage: There is no back pressure from the inside of the bag to fix the valve.

Preferably, the bag is sterilized and the wrapper or prefabricated container, and more preferably the screw cap, are not sterilized.

In the sterilization of consumables today are sterile fluids such. As hydrogen peroxide but also irradiation by aseptic light sources or gamma rays available. The sterile bath is preferably used in the process according to the invention. However, it may also be replaced by irradiation, steaming, sprinkling, heating, frostbite, negative pressure or overpressure or other sterilizing procedures. It's just about killing all sorts of germs and bacteria during treatment.

In the method according to the invention, for example, a variety of forms can be used - completely or partially surrounded by an outer shell, preferably made of cardboard but also from any other materials that give stability, but for example, only the finished shaped and filled bag out of the clean room transported out and the stability-giving Sheath is placed around the bag in a very normal environment and therefore does not need to be sterilized.

This has the advantage that the stability-giving sheath does not have to undergo any sterile treatment and, as a result, a treatment of the sheath, such as lacquer against moisture or discoloration by irradiation or heat treatment, can also be used. Also eliminates complex technology in expensive clean room. As a result, a much wider range of creative possibilities can be exploited in the design. Thus, it is even possible, for example, to use special colors which react to temperature or time in order to indicate to the consumer, for example, how old the packaging is or whether the filling material has a certain optimum consumption temperature. So you could also indicate that the cold chain was interrupted once.

Preferably, in step b. to a prefabricated container made of cardboard, the carton only immediately before step b. is formed into a container.

Incidentally, today you can weld all foils, for example, but also connect them with ultrasound technology. This has the advantage that even a slightly moist or wetted by the filling material weld can be tightly connected. The contamination can z. B. by climbing up the contents (capillary action) arise. If you fill, for example, in the level, so would be squeezed in a conventional manner, the bag so that here a great effort is necessary, which would ultimately mean energy expenditure again. Ultrasonic welding does not require this high pressure.

In previous systems that do not work in this way, such as. B. the U.S. Patent 5,156,295 or in the so-called Capri Sun, the bag is heated after or during the filling to a temperature of at least 70 degrees to kill all germs and bacteria. Then the entire bag is cooled down again. That has that Disadvantage that this requires a lot of time, a lot of energy is wasted and the product suffers greatly from the temperature differences.

In addition, in these systems is usually filled by the valve, thus a valve would be very expensive and the filling process takes much more time. Of course, this approach would be possible when accepting these disadvantages.

Of course, one can also work in this way, for example, in the method according to the invention. This is possible, for example, with a bag without outer carton or with an already filled cardboard. This would have the disadvantage that you then have to accept the disadvantage of heating and cooling down.

It is important, for example, that the bag rests as close as possible to the carton. For example, the bag can accommodate most of the load of stacked bags on a pallet. Such a bag can carry up to 190 kg or more of load, depending on the film thickness. In order to build a box of the same load capacity, one would have to use a very thick wall thickness, which is then considerably more expensive than a bag with the same load capacity.

Since it is allowed to load up to 33 pallets in a truck that is currently in operation and only up to 24.5 tons may be loaded in Europe, only 28 pallets are often loaded onto a truck. These weigh then including wood about 900 kg. This results in the following packing scheme:
z. B. in the following packing scheme (attention, other pack sizes may result in other value)
1st layer: 4 x 3 pieces of pack of 12 = 144 packs per ply = 1056 grams / bag by 144 packs = 152 kg / ply 900 kg - 25 kg (empty pallet) = 875 kg / 152 kg = 5.76 ply

For example, if a beverage carton is in its lowermost position, it should weigh approximately 5 x 152 kg = 760 kg / 144 packages = 5,277 kg.

In addition, the truck can get bumps through rough roads and thus the weight is often doubled or multiplied. For example, a beverage carton should certainly be able to carry up to 25 kg.

In other countries, transport may also be common, which can accommodate even higher transport loads, and thus our system is also advantageous in these countries, as theoretically pallets could be used up to 10,000 kg carrying capacity on the lower layer.

Since the space in some large distribution warehouses is always very scarce, up to 5 or more pallets of our system can be stacked on top of each other by taking up the load through the inner bag and thus lower logistics costs.

For example, since untreated cardboard can easily be softened by moisture such as condensation or even high humidity, it may be necessary for the inner bag to take up most of the load, only so may a special treatment or the use of much of the outer carton or sheath material be saved.

To possibly still occurring moisture z. For example, by keeping condensation water or humidity away from the carton, it would also be possible, for example, to weld a 1, 2, 3, 4 or 60 pack, or even an entire pallet, with a moisture resistant film to be sure that there is no moisture comes to the wrapper and thus a softening is prevented.

But you could also, for example, the material of the wrapper with a water-repellent color, a particularly smooth surface or a 2-coat with rough inner part and high-quality paper from the outside, possibly by nanotechnology or by using the lotus technique so treat that the envelope no moisture can record.

However, the inner bag could for example also be shaped so that it is firmly connected to the outer shell only at the upper side and the lower side by the internal pressure and has some space on the sides. This would for example have the advantage that when gripping the outer packaging, which usually takes place on the side walls, no pressure on the inner bag is applied and thus spills the contents, especially in a completely filled state from the spout.

In addition, this would have the advantage that due to the air in the interior between bag and casing, so to speak acts as insulation and thus the contents remain cool for longer during transport.

Preferably, in the method according to the invention, before the bag is filled, a part of the screw cap, in particular a base plate, is placed on the bag, the bag is sterilized with this part of the screw cap, and the screw cap is not completed with the remaining parts of the screw cap until later. This has the decisive advantage that the crucial part of the screw cap is sterile and on the other hand in the valve no sterilization solution can collect and before In addition, not all the screw cap needs to be sterilized.

In the method according to the invention, it is preferable to use a bag with a barrier barrier, the barrier barrier being selected in particular from SIOX, EVOH and / or ALU.

In a further embodiment, the object underlying the invention is achieved by a filled packaging produced according to the invention, characterized in that the bag fills at least 90% of the internal volume of the packaging.

• a. einen Verschlusssockel, i. der einen flächigen Sockelboden zur Verbindung mit einem zu verschließenden Behälter aufweist, und ii. der senkrecht zum Sockelboden einen mit dem Sockelboden fest verbundenen Sockelring aufweist, wobei (I) der Sockelboden innerhalb des Sockelrings zumindest teilweise ausgespart ist, (II) der Sockelring auf der Außenseite ein rechtsdrehendes Außengewinde und/oder eine Einrastmöglichkeit für eine Verschlusskappe aufweist, und (III) der Sockelring auf der Innenseite einen linksdrehenden Gewindegang aufweist,
• b. einen Schneidring, i. der in dem Sockelring geführt ist, ii. der an demjenigen Ende, das dem Sockelboden zugewandt ist, im Folgenden als Aufschneidende bezeichnet, Aufschneidzähne oder/oder wenigstens eine scharfe Kante aufweist, und iii. der oberhalb des Aufschneidendes ein linksdrehendes Außengewinde aufweist, das in den linksdrehenden Gewindegang des Sockelrings eingreift, wobei das Aufschneidende der Aussparung im Sockelboden zugewandt ist,
• c. eine Verschlusskappe, i. die auf der Innenseite einen rechtsdrehenden Gewindegang, der in das rechtsdrehende Außengewinde des Sockelrings eingreift, und/oder eine Einrastmöglichkeit für den Sockelring aufweist,

wobei die Verschlusskappe und der Schneidring so ausgestaltet sind, dass ein Drehen der Verschlusskappe wenigstens beim erstmaligen Öffnen des Schraubverschlusses den Schneidring in Richtung des Sockelbodens bewegt.Preferably, the filled package comprises a screw cap for a beverage package, characterized in that it comprises at least the three following elements:

• a. a lock socket, i. having a flat base bottom for connection to a container to be sealed, and ii. (S) the base bottom is at least partially recessed within the base ring, (II) the base ring on the outside has a right-handed external thread and / or a latching possibility for a cap, and ( III) has the base ring on the inside a left-handed thread,
• b. a cutting ring, i. which is guided in the base ring, ii. which at the end, which faces the base bottom, hereinafter referred to as Aufschneidende, cutting teeth or / or at least one sharp edge, and iii. which has a left-handed external thread above the slicing end, which engages in the counterclockwise thread turn of the base ring, the slicing end facing the recess in the base bottom,
• c. a cap, i. having on the inside a dextrorotatory thread, which engages in the dextrorotatory external thread of the base ring, and / or a latching possibility for the base ring,

wherein the closure cap and the cutting ring are configured such that a rotation of the closure cap moves the cutting ring in the direction of the base bottom at least when first opening the screw cap.

Preferably, either in the cap ( 19 ) or in the cutting ring ( 13 ) at least one driver ( 23 ) arranged in guide grooves ( 25 ) of the respective complementary part ( 13 or 19 ) engages, so that turning the cap ( 19 ) at least when first opening the screw cap ( 1 ) the cutting ring ( 13 ) in the direction of the base ( 5 ) emotional.

Preferably, within the cutting ring, a membrane made of an elastic material, in particular of rubber or silicone, is arranged on the side in the direction of the cap of a membrane support, so that the beverage can be poured out through the membrane support by the weight of the beverage, the membrane of the Deflects diaphragm support away. This creates a de facto valve.

By allowing the fluid-carrying bag to collapse, a valve in the spout for durability can be a tremendous advantage. Since the contents are not contaminated with germs and bacteria by air flowing in as a carrier of bacteria and germs, the durability of the medium in the open state is significantly extended. This applies to aseptic packaging as well as non-aseptic packaging.

So that also liquid, lumpy, honey-like as well as bulk goods such as honey, jam, fruits, vegetables, in the most different conditions can be filled, for example the most different spout variants are conceivable. These can again be pre-fabricated in the non-aseptic area with no opening mechanism to the bag or in the aseptic area with Aufschneidmechanismus, directly on the package or by external tools such as a pair of scissors, knives or special tools that can be purchased separately. It is also conceivable, for example, that the opening is so large that you can easily with a spoon, z. For example, it would also be possible to have a separate pump or even a machine to be supplied separately for the purpose of conveying. But it is also smaller, or completely without a valve, such. B. the insertion of a straw.

For reclosing, for example, a lid, a zipper, a hook-and-loop fastener, a nonpermanent adhesive closure, a pressure-lock closure, a flip-up closure, or any other closure can be used. The closures can be closed when closing by snapping, jamming, by oval latching but also simply as a screw cap again.

So that the contents can be mixed again before opening, for example, could also be a small ball or a ball, similar to working with a paint spray can, be put into the bag.

Preferably, the membrane is removable in particular by a nipple connected to the membrane.

Since with an almost empty container, the weight of the filling material to open the membrane is no longer sufficient, the valve can be designed so that the valve diaphragm is then simply pulled out to then ensure the free outlet for the remaining amount. This works for all valve versions mentioned above when inserting the valve in front of the clean room as well as after the clean room.

Preferably, a tight cover with predetermined breaking points is arranged in the recess in the base bottom within the base ring, which can be easily pierced by the cutting end of the cutting ring when turning the screw cap.

• a. einen Füllautomaten zum Befüllen des Beutels, der vor oder nach der Befüllung einen Schraubverschluss mit dem Beutel verbindet,
• b. einen Kartonierer, der Karton um den Beutel herum zu einem Behälter faltet oder einen vorgefertigten Behälter aus Karton einsetzt, wobei der Kartonierer das Ventil mit dem Behälter fest verbindet und
• c. einen automatischen Palettisierer.

In a further embodiment, the object underlying the invention is achieved by a filling system for carrying out the method according to one of claims 6 to 9, characterized in that it comprises the following components,

• a. a filling machine for filling the bag, which connects a screw cap with the bag before or after filling,
• b. a cartoner that folds carton around the bag into a container or inserts a prefabricated container from carton, the cartoner firmly connecting the valve to the container, and
• c. an automatic palletizer.

Since the previous beverage cartons are already very optimized in terms of space required in relation to the required material, the previous machines of conventional drinks card manufacturers could be modified, for example, so that it also fills the thinner foil instead of the composite material used in the same form and then afterwards the carton is also placed outside of the sterile room or inserted into the prefabricated packaging. For example, you only need an additional cartoner between the filling machine and the automatic palletizer.

This has the advantage that the stabilizing outer packaging does not have to be sterilized at all. As already mentioned, it would also be possible, for example, to install the valve only outside the sterile room and then place or insert the outer packaging around the inner bag.

It would also be possible, for example, to connect the valve to the envelope and connect it to the inner bag from the outside only after it has been folded around the inner bag.

This has the further advantage that the carton does not need to be treated, for example, so as not to become full of liquid / disinfectant (hydrogen peroxide). For if the bag is filled aseptically times, for example, the carton does not need to be sterile anymore because it no longer comes into contact with the contents.

Depending on the contents, for example, the most optimal and most cost-effective valve can be used. For example, you need a different valve for a liquid than for liquid with solids such. As peas in water or tomato paste. Here it must be taken into account that the contents flow only very little. If necessary, then, for example, in carton a buckling mechanism or an additional slider z. B. be made of cardboard in the envelope, so that a complete emptying of the filling material can be guaranteed.

It is important, for example, that the inner bag can be easily separated from the outer wrapper after use. For this purpose, for example, a predetermined breaking point open the box or the inner bag can be easily pulled out so that can be disposed of separately at any time.

• – eine optimale Materialeinsparung,
• – ein optimale Restentleerung,
• – ein für eine eventueller Knickmechanismus für die Restentleerung
• – eine optimale Tragekraft
• – eine optimale Getrenntentsorgung
• – bei so wenig wie möglich Verklebungen oder Verbindungen
• – ein optimaler Ventilsitz für Logistik und Endverbraucher

je nach Füllgut gewährleistet wird. Daher sind beispielsweise die verschiedensten Beutelformen aufgrund der jeweiligen Anforderungen denkbar. So könnten beispielsweise fast alle Materialien des täglichen Bedarfs hier abgefüllt werden, auch Materialien, die heute in Blechdosen, Getränkekartons, Standbeuteln, Klarsichtverpackungen, Deckeln etc. sind denkbar. Die Abfüllung von beispielsweise gemischten Waren in Beutel mit einem Karton darum ist erstmals möglich.For example, when selecting the shape of the bag, care must be taken to ensure that:

• - an optimal material saving,
• - an optimal emptying,
• - One for a possible buckling mechanism for emptying
• - an optimal carrying power
• - an optimal separate disposal
• - with as few as possible bonds or connections
• - an optimal valve seat for logistics and end users

Depending on the product is guaranteed. Therefore, for example, the most diverse bag shapes due to the respective requirements are conceivable. For example, almost all materials for daily use could be bottled here, including materials that are currently conceivable in tin cans, beverage cartons, stand-up pouches, transparent packaging, lids, etc. The filling of, for example, mixed goods in bags with a carton for the first time is possible.

By cold aseptic or refrigerated non-aseptic packaging of food they remain in the consistency with autoclaved Fillings of the original form similar and nutrients, vitamins, etc. are better preserved.

When selecting the coating, for example, make sure that the contents can be emptied easily and practically. For this purpose, for example, suitable Vorfalzungen in the envelope are possible, which then make firmer substances herauspressbar from the pack.

Another advantage of the inventive system is the delivery of the packaging material. In previous beverage textures, either the composite material that is very rigid is delivered to rolls or a prefabricated beverage carton, which is then set up by a machine. Since the material is very thick and has up to 7 or more layers, this material is very difficult to wrap or fold, taking up a lot of space during storage and transport. Even prefabricated bags with already folded cardboard, such as the Edelmann principle or other version can not be optimally folded together.

In the system according to the invention can be very large amounts of film with up to several 1,000 linear meters z. B. be delivered on a roll and consume a lot less space than the previous system. In the case of the cardboard used, it is even possible to work preferably only with blanks cut out flat, which in the ideal case are not even kinked, so that an optimal transport characteristic also exists here. Only in the machine, the bag is formed and folded the box so that it gets its stable property later. This has enormous logistical advantages in terms of storage and transport costs.

Of course there can also be mixed versions. That would be z. B. interesting for smaller manufacturers who do not want to afford the complex machine technology. Here also prefabricated bags or boxes could be delivered. Cartons, z. B. with automatic floor or even with a glue, so that you only have to put the coat together. Even these prefabricated boxes require less space during storage and transport.

In addition, the materials used can be produced in most film and carton factories and, therefore, require no special material-making machinery. This can also save time consuming and extensive transport routes.
