Abstract

The system involves a device for carrying out a shaping stage or for introducing shaping components and comprises at least one press cushion or form matrix for introduction of the adhesion positions. It may also comprise a pair of folding or rolling tools (31). The sample bag, in addition to the closure seams (6, 6') has at least one additional adhesion position connecting the foil strips (1'). The bag has two opposing, rolled-in or folded-in edges. Double longitudinal seams (6') are incorporated, and between the individual seams at least one of the foils has a fold running parallel to the longitudinal seams.

Description

Die Erfindung liegt im Gebiet der Verpackungstechnik und betrifft ein Verfahren zur Herstellung von Musterbeuteln nach dem Oberbegriff des ersten, unabhängigen Patentanspruchs sowie eine Vorrichtung zur Durchführung des Verfahrens und nach dem Verfahren hergestellte Musterbeutel. Die hergestellten Musterbeutel enthalten fluide oder feste Muster und sind insbesondere geeignet für eine automatisierte Weiterverarbeitung mit hoher Verarbeitungsgeschwindigkeit, beispielsweise für das Anbringen an oder das Einbringen in Druckprodukte.The invention lies in the field of packaging technology and relates to a method for producing sample bags according to the preamble of the first, independent patent claim and an apparatus for carrying out the method and sample bags produced according to the method. The sample bags produced contain fluid or solid samples and are particularly suitable for automated further processing at high processing speeds, for example for attaching to or introducing them into printed products.

Das Einstecken, Sammeln, Zusammentragen etc. von zusätzlichen Drucksachen in Druckprodukte, insbesondere in Periodika (z.B. in Zeitungen, Zeitschriften, Hefte, Prospekte, auch Bücher etc.) hat sich mittlerweile auch auf weitere Beilagen ausgedehnt, die dem Druckprodukt mitgegeben werden sollen. Sehr beliebt sind Beilagen in Form von Musterbeuteln, die feste Gegenstände, bspw. Reinigungstüchlein oder fluide Musterprodukte, bspw. Crèmen, Pasten, Flüssigkeiten etc, enthalten. Die Beutel bestehen üblicherweise aus zwei allseitig miteinander verbundenen Zuschnitten eines Verpackungsmaterials, beispielsweise einer meist mehrlagigen Kunststoff/Papier-Folie.The insertion, collection, collation etc. of additional printed matter in printed products, in particular in periodicals (e.g. in newspapers, magazines, booklets, prospectuses, also books etc.) has meanwhile also expanded to include other supplements that are to be given to the printed product. Supplements in the form of sample bags are very popular and contain solid objects, e.g. cleaning wipes or fluid sample products, e.g. creams, pastes, liquids, etc. The bags usually consist of two blanks of packaging material that are connected to one another on all sides, for example a mostly multi-layer plastic / paper film.

Die Technik der Handhabung von Beilagen in Form von flächigen Drucksachen wie Karten etc. ist bekannt und recht ausgereift. Die maschinellen Mittel sind vorhanden, hohe, dem Gesamtprozess angepasste Geschwindigkeiten sind in der Regel erreichbar. Mit der Handhabung von Beuteln im weitesten Sinne steht man jedoch vor ganz neuen Problemen. Beutel haben in aller Regel keine definierte Form, sie sind beispielsweise kissenförmig, also nicht, wie gewünscht, flach und sie sind oft nicht mal an derselben Stelle nach aussen bombiert. Bei fluiden Inhalten verändert sich die Form bei jeder Handhabung. Ausserdem wird die Handhabung auch noch dadurch erschwert, dass das Material der Beutel aus Kunststoffen mit glatter, gleitender Oberfläche besteht, sodass die beim Stapeln normalerweise hilfreichen Reibungskräfte nur klein sind. Stangen von Beutein, das sind geordnete Stapel, sind unstabil und daher kritisch in der Verarbeitung, insbesondere bei hohen Verarbeitungsgeschwindigkeiten.The technique of handling inserts in the form of flat printed matter such as cards etc. is known and quite mature. The mechanical means are available, high speeds that are adapted to the overall process can usually be achieved. However, handling bags in the broadest sense poses completely new problems. Bags generally have no defined shape, for example they are pillow-shaped, i.e. not flat as desired, and they are often not even cambered outwards in the same place. With fluid content, the shape changes with each use. In addition, handling is made even more difficult by the fact that the material of the bags consists of plastics with a smooth, sliding surface, so that the frictional forces that are normally helpful when stacking are only small. Beutein bars, which are ordered stacks, are unstable and therefore critical in processing, especially at high processing speeds.

Diese Problematik wird durch die Erfindung gelöst. Als das grösste Hindernis für eine prozessgerechte Handhabung der Musterbeutel beim Einbringen in Druckprodukte wurde die für eine Stangenbildung sehr ungünstige und in vielen Fällen unstabile, das heisst während der Handhabung sich verändernde Form ausgemacht. Es ist also das Ziel der Erfindung, den Beuteln in einem gegenüber dem Stande der Technik entsprechend modifizierten Herstellungsverfahren eine stabilisierte und auch möglichst flache Form zu geben, welche Form es erlaubt, die Beutel wunschgemäss handhaben zu können. Durch die Stabilisierung der Beutelform soll eine Veränderung der Beutelform durch eine Verschiebung des Inhaltes bei der Manipulation möglichst verhindert werden. Ferner soll eine kissenförmige Beutelform mit im wesentlichen elliptischem Querschnitt entweder vermieden oder ihr Einfluss auf die Stangenbildung durch weitere formgebende Mittel beschränkt werden.This problem is solved by the invention. The greatest obstacle to process-oriented handling of the sample bags when they are introduced into printed products has been identified as the very unfavorable and in many cases unstable form of bars, i.e. the shape that changes during handling. It is therefore the aim of the invention to give the bags a stabilized and also as flat a shape as possible in a manufacturing process modified according to the prior art, which shape allows the bags to be handled as desired. By stabilizing the bag shape, a change in the bag shape by shifting the contents during manipulation is to be prevented as far as possible. Furthermore, a pillow-shaped bag shape with an essentially elliptical cross section should either be avoided or its influence on the rod formation should be limited by further shaping means.

Dieses Ziel wird durch die in den Patentansprüchen definierte Erfindung erreicht. Schon bei der Herstellung der gefüllten Beutel werden diese auf den späteren Verarbeitungsprozess konditioniert, indem zur Stabilisierung der Beutelform zusätzliche, formgebende Schritte in das Herstellungsverfahren integriert werden und/oder indem zusätzliche Formelemente in das Herstellungsverfahren eingebracht werden.This aim is achieved by the invention defined in the claims. Already during the production of the filled bags, these are conditioned for the later processing process by integrating additional shaping steps into the manufacturing process to stabilize the bag shape and / or by introducing additional shaped elements into the manufacturing process.

Die zusätzlichen Schritte zur Formstabilisierung werden derart in den Herstellungsprozess der Beutel integriert, dass kaum ein prozessmässiger Mehraufwand entsteht. In der Regel muss durch die Formstabilisierung bei der Beutelherstellung auch kein Geschwindigkeitsverlust in Kauf genommen werden. Auf der Werkzeugseite ist gegebenenfalls ein, gemessen an den erzielten Vorteilen, jedoch geringer Mehraufwand nötig.The additional steps for shape stabilization are integrated into the bag manufacturing process in such a way that hardly any additional work is required. As a rule, the shape stabilization during bag manufacture means that there is no loss of speed. On the tool side, a small additional effort may be necessary, based on the advantages achieved.

Die nach dem erfindungsgemässen Verfahren hergestellten Musterbeutel sind vereinzelt oder am Strang sehr viel einfacher handhabbar als bekannte Musterbeutel, da sie eine stabilisierte, das heisst bei der Handhabung sich nur noch unwesentlich verändernde und möglichst flache Form aufweisen. Man kann sie aus diesem Grunde problemlos mit bekannten Mitteln zu Stangen aufreihen, einzeln greifen und weiterverarbeiten, insbesondere auch mit hohen Verarbeitungsgeschwindigkeiten. Im Druckprodukt trägt das geflächte, als möglichst flach gemachte Musterprodukt nicht mehr unnötig auf, man kann also pro Druckprodukt mehr solcherweise perfektionierte Musterprodukte bzw. Musterbeutel einbringen als zuvor.The sample bags produced by the method according to the invention are isolated or can be handled much more easily on the strand than known sample bags, since they have a stabilized shape, that is to say that they only change insignificantly during handling and are as flat as possible. For this reason, they can be easily strung into bars with known means, individually gripped and further processed, in particular also at high processing speeds. In the printed product, the flattened sample product, which has been made as flat as possible, is no longer unnecessarily applied, so more sample products or sample bags perfected in this way can be introduced per print product than before.

Das Prinzip, wie der Verpackungsvorgang im wesentlichen abläuft ist bekannt: Ab Rollen 1 werden in Pfeilrichtung z (klein z zeigt die Prozessrichtung des Produktes an) Folienbahnen 1' mit bspw. einer wärmeschmelzbaren Beschichtung über Umlenkrollen 3 in einen Anlageteil 10 zur Aufnahme des Musterproduktes 2 gezogen. In diesem Anlageteil 10 werden die Folienbahnen durch Bildung von kontinuierlichen Längsnähten und äquidistanten Quernähten 6 zu Beuteln geschlossen, wobei die entstehenden Beutel jeweils zwischen der Erstellung von aufeinanderfolgenden Quernähten 6 beispielsweise mit einem festen Gegenstand 2 befüllt werden. Da der Verschliessvorgang bekannt ist, wird er hier ebenfalls nur skizziert dargestellt weswegen nur die in Pfeilrichtung Z (gross Z zeigt Bewegungen von Vorrichtungsteilen an) sich schliessenden Verschlusselemente 4, bspw. Heizelemente zur Bildung der abschliessenden Verschlussquernaht 6 der Beutel 12 dargestellt sind, die Verschlusselemente für die Verschlusslängsnaht sind in dieser Figur weggelassen. FIG. 1 shows in a very schematic manner an installation for packaging sample products in bags, as is used according to the prior art. The principle of how the packaging process essentially proceeds is known: From rolls 1, film webs 1 'with, for example, a heat-fusible coating via deflection rollers 3 into a system part 10 for receiving the sample product 2 become arrow direction z (indicates the process direction of the product) drawn. In this plant part 10, the film webs are closed into bags by forming continuous longitudinal seams and equidistant transverse seams 6, the resulting bags each being filled with a solid object 2 between the creation of successive transverse seams 6, for example. Since the closing process is known, it is also only shown here in a sketched manner, which is why only the closing elements 4 closing in the direction of arrow Z (large Z indicates movements of device parts), for example heating elements for forming the final closing transverse seam 6 of the bags 12, are shown, the closing elements for the longitudinal closure seam are omitted in this figure.

Die Beutel 12, die als quasi endloser Beutelstrang aus dem Anlageteil 10 austreten, werden üblicherweise anschliessend im Bereiche der Quernähte 6 voneinander getrennt. Die fertigen Musterbeutel 12 sind typisch kissenförmig.The bags 12, which emerge from the plant part 10 as a quasi-endless string of bags, are usually subsequently separated from one another in the region of the transverse seams 6. The finished sample bags 12 are typically pillow-shaped.

Figuren 2 und 2a illustrieren eine erste, beispielhafte Variante des erfindungsgemässen Verfahrens und das entsprechende Produkt. Nach dieser Verfahrensvariante wird als zusätzliche, formgebende Massnahme vor dem Verschliessen des Beutels (Erstellung der Quernaht 6 nach dem Befüllen) möglichst viel Luft aus dem Beutel gepresst. Versuche an Beuteln mit je einem Frischhaltetuch, als Beispiel eines festen Musterproduktes, haben gezeigt, dass ein Abpressen der Luft aus dem Beutel überraschend gute Resultate zum vorgegebenen Ziel ergibt. Figures 2 and 2a illustrate a first, exemplary variant of the method according to the invention and the corresponding product. According to this method variant, as much additional air as possible is pressed out of the bag as an additional, shaping measure before the bag is closed (creation of the transverse seam 6 after filling). Experiments on bags with a fresh wipe each, as an example of a solid sample product, have shown that squeezing the air out of the bag gives surprisingly good results for the specified goal.

Figur 2 zeigt in derselben Weise wie Figur 1 eine Anlage zur Durchführung der genannten Verfahrensvariante (gleiche Bezugsziffern für bereits beschriebene Teile). Das Abpressen erfolgt schrittweise durch weiche, im wesentlichen in Richtung Z hin und her bewegbare Presselemente 5, bspw. Polyurethankissen, welche den Beutel durch Auspressen der überflüssigen Gasrückstände in die gewünschte Form bringen. Die Presselemente 5 sind beispielsweise, wie dargestellt ein bewegbares Kissen und eine entsprechende Gegenauflage oder sie sind zwei sich für die Auspressung gegeneinander bewegende Kissen. Die Presselemente 5 sind in demselben Anlageteil 10 angeordnet wie der Schweisskopf 4 für die Erstellung der Verschlussquernaht. FIG. 2 shows, in the same way as FIG. 1, a system for carrying out the aforementioned method variant (same reference numbers for parts already described). The pressing is carried out step by step by means of soft pressing elements 5, for example polyurethane cushions, which can be moved back and forth essentially in the Z direction and which bring the bag into the desired shape by pressing out the superfluous gas residues. The pressing elements 5 are, for example, as shown, a movable cushion and a corresponding counter support, or they are two cushions that move against each other for the pressing. The pressing elements 5 are arranged in the same system part 10 as the welding head 4 for the creation of the sealing cross seam.

Die fertig verschweissten Musterbeutel sind, wie Figur 2a zeigt, flach, in einem gewissen Sinne rigid, behalten ihre Form und verhalten sich bei der Handhabung viel mehr wie ein flächiges Musterprodukt als der in der bekannten Art hergestellte Musterbeutel (Figur 1a), der ein weich gepolsterter, kissenartiger Gegenstand ist. Die mit dem erfindungsgemässen Verfahren erzielte Festigkeit ist genau das, was auch angezielt wurde und bringt im nachfolgenden Verarbeitungsprozess der Beutel mit den Druckprodukten die Handhabungsmöglichkeiten, welche für hohe Verarbeitungsgeschwindigkeiten vorausgesetzt sind.The finished, welded sample bags, as shown in FIG. 2a, are flat, rigid in a sense, retain their shape and behave much more like a flat sample product when handled than the sample bag produced in the known manner (FIG. 1a), which is soft padded, pillow-like object. The achieved with the inventive method Strength is exactly what was aimed at and in the subsequent processing of the bags with the printed products brings the handling options that are required for high processing speeds.

Figur 3 zeigt einen Anlageteil 10 in Anlehnung an Figur 2 für kontinuierliche Formstabilisierung von Beuteln mit festem Inhalt durch Abpressen von Luft. Die Verschlusselemente 20 für die Längsverschlussnaht und die Verschlusselemente 4 für die Querverschlussnaht, sowie die Presselemente 5 zum Formstabilisieren der Beutel sind in zwei Walzen bzw. Formmatrizen integriert, zwischen denen mittels einer Verschlusslängsnaht 6' die Aufnahmekammer für das einzufüllende Musterprodukt gebildet wird, zwischen denen das Auspressen des überschüssigen Gases stattfindet und zwischen denen schliesslich die Verschlussquernaht 6 angelegt wird. Die Presselemente 5 bestehen aus einem weichen, schmiegsamen Material, welches beim Pressen das im Beutel befindliche Musterprodukt 2 nicht beschädigt. Durch gegenläufige Drehrichtung der Walzen gemäss Richtungspfeilen Z wird das partiell umhüllte Musterprodukt in Pfeilrichtung z gefördert, gleichzeitig längsnahtgeschlossen, konditioniert (formstabilisiert) und darauf mittels einer Querverschlussnaht verschlossen. Dazu dienen die in Achsrichtung der Walzen verlaufenden Querstege 4 (Verschlusselemente). Es ist hier offen gelassen, ob der Verschluss durch Rippenbildung oder durch eine Verschweissung oder auf eine weitere Art herbeigeführt wird. Figure 3 shows a plant part 10 based on Figure 2 for continuous shape stabilization of bags with a solid content by squeezing air. The closure elements 20 for the longitudinal closure seam and the closure elements 4 for the transverse closure seam, as well as the pressing elements 5 for stabilizing the shape of the bags, are integrated in two rollers or form matrices, between which the receiving chamber for the sample product to be filled is formed by means of a longitudinal closure seam 6 ', between which the Squeezing of the excess gas takes place and between which the sealing cross seam 6 is finally applied. The pressing elements 5 consist of a soft, pliable material which does not damage the sample product 2 in the bag during pressing. By reversing the direction of rotation of the rollers according to directional arrows Z, the partially covered sample product is conveyed in the direction of arrow z, at the same time closed longitudinally, conditioned (shape-stabilized) and then closed by means of a transverse seam. The transverse webs 4 (closure elements) running in the axial direction of the rollers serve for this purpose. It is left open here whether the closure is brought about by rib formation or by welding or in another way.

Figuren 4, 4a und 4b zeigen wiederum anhand einer sehr schematisch dargestellten Anlage eine weitere Variante des erfindungsgemässen Verfahrens und das entsprechende Produkt. In dieser Variante, die sich insbesondere für fluide Musterprodukte eignet, wird die Formstabilisierung durch Erzeugung von Haftstellen in der Aufnahmekammer der Beutel erzielt, an welchen Haftstellen die beiden Folienbahnen 1' wie in den Nahtbereichen aneinander haften oder miteinander verbunden sind. FIGS. 4, 4a and 4b in turn show a further variant of the method according to the invention and the corresponding product using a very schematically represented system. In this variant, which is particularly suitable for fluid sample products, the shape stabilization is achieved by creating adhesion points in the receiving chamber of the bags, at which adhesion points the two film webs 1 'adhere to one another or are connected to one another as in the seam regions.

Versuche an Beutein mit crèmigem Inhalten zeigen, dass durch das Einpressen eines Kammersystems (linienförmige Haftstellen), das ein Entleeren des Beutels nicht nur nicht behindert sondern auch unterstützen kann, dieselben befriedigenden Resultate für die Weiterverarbeitung der Beutel erreicht werden können. Je nach Beutelabmessung werden mehrere Lagerkammern eingeprägt, welche alle in eine Sammelkammer münden, die ihrerseits mit dem Ausguss des Beutels verbunden ist. Die Lagerkammern stabilisieren den Inhalt des Beutels in Lage und Volumen. In einer anderen Form der Stabilisierung wurde versucht, durch lediglich punktförmige Haftstellen eine matratzenartige, quasiflache Beutelform zu erhalten und damit ein Verschieben des Inhaltes bei der Handhabung mindestens zu erschweren. Das Füllgut kann sich nach solchen Massnahmen nicht mehr an einem Ort sammeln und eine unregelmässig kissenförmige Ausbauchung erzeugen.Tests on bags with creamy contents show that by pressing in a chamber system (line-shaped adhesive points) that not only does not prevent the bag from being emptied but can also support it, the same satisfactory results can be achieved for the further processing of the bags. Depending on the size of the bag, several storage chambers are embossed, all of which open into a collecting chamber, which in turn is connected to the spout of the bag. The storage chambers stabilize the contents of the bag in position and volume. In another form of stabilization, attempts have been made to obtain a mattress-like, quasi-flat pouch shape by merely punctiform adhesive points and at least to make it difficult to move the contents during handling. After such measures, the filling material can no longer collect in one place and produce an irregular pillow-shaped bulge.

Die Haftstellen werden entweder mittels einer Taktpressung oder mittels einer Rollenpressung eingebracht. Die gebildeten Anker- oder Haftstellen. punkt- oder linienförmig, müssen bezüglich Zusammenhalt nicht dieselbe Widerstandskraft aufweisen wie die gesamte Verschlussnaht um die Peripherie des Beutels bzw. des Musterprodukts. Solcherart hergestellte Beutel sind in jeder Lage "flach". Da kleine Lecks zwischen den Kammern die gewünschten Eigenschaften des Beutels nicht beeinflussen, ist auch die nachfolgende Handhabung nicht kritisch. Schon ein punktweises Fixieren mit wenigen Haftstellen zu "polsterförmigen" Vertiefungen verhindert eine Kissenbildung des Beutels.The points of detention are introduced either by means of a cycle pressure or by means of a roller pressure. The anchor or detention points formed. point or line-shaped, do not have to have the same resistance to cohesion as the entire sealing seam around the periphery of the bag or the sample product. Bags made in this way are "flat" in any position. Since small leaks between the chambers do not affect the desired properties of the bag, the subsequent handling is also not critical. Even a point-by-point fixation with a few adhesive points to "cushion-shaped" depressions prevents the bag from forming a cushion.

Die Herstellung der Haftstellen erfolgt bspw. am fertigen Musterprodukt, wobei nicht in jedem Falle Wärme eingesetzt werden kann, das heisst, dass mit dem Begriff Verschweissen auch der Begriff Verschliessen durch andere Verbindungsmethoden gemeint ist. Bei der punktförmigen Verbindung kann die Befüllung des Beutels mit dem fluiden Musterprodukt auch mittels einer rückziehbaren Kanüle nach der Verankerung der Folien geschehen.The attachment points are produced, for example, on the finished sample product, heat not being able to be used in every case, that is to say that the term welding also means the term closing by other connection methods. In the case of the punctiform connection, the bag can also be filled with the fluid sample product by means of a retractable cannula after the films have been anchored.

Figur 4 zeigt eine Anlage zur Herstellung der oben beschriebenen, durch zusätzliche Haftstellen formstabilisierten Beutel mit fluidem Inhalt. Es wird Wert darauf gelegt zu zeigen, dass die Stabilisierungsmassnahme wiederum durch Presselemente 5' realisiert wird, welche Presselemente für fluide und für feste Inhalte (Presselemente 5 in Figur 2) grosse Ähnlichkeit zueinander aufweisen. Die Presselemente zur Erzeugung der Haftstellen (bei fluidem Inhalt) sind je nach Verbindungsmethode der Beutelinnenoberflächen zusätzlich beispielsweise beheizt oder mit Ultraschall beaufschlagbar. Eine solche Lösung macht den Einsatz an bekannten Füllmaschinen sehr sinnvoll. Deswegen und auch absichtlich sind die Figuren 2 und 4 (bzw. 3 und 5) für feste und für fluide Musterprodukte im Taktbetrieb (bzw. im kontinuierlichen Betrieb) sehr ähnlich. Im wesentlichen wird das Presselement 5 oder 5' entsprechend der Stabilisierungsmassnahme variiert: einmal ist es ein Kissen zum Auspressen von überschüssigem Gas, andermal ist es eine Formmatrize zur Erzeugung der Haftstellen. FIG. 4 shows a system for producing the above-described bags with fluid content, which are stabilized by additional adhesive points. It is important to show that the stabilization measure is again implemented by pressing elements 5 ', which pressing elements for fluid and for solid contents (pressing elements 5 in FIG. 2) are very similar to one another. Depending on the connection method of the inner surface of the bag, the pressing elements for creating the adhesion points (with fluid contents) are additionally heated, for example, or can be subjected to ultrasound. Such a solution makes the use of known filling machines very useful. For this reason and also on purpose, FIGS. 2 and 4 (or 3 and 5) for solid and for fluid sample products in cyclical operation (or in continuous operation) are very similar. Essentially, the pressing element 5 or 5 'is varied in accordance with the stabilization measure: on the one hand it is a cushion for pressing out excess gas, on the other hand it is a molding die for creating the adhesion points.

Das Einfüllen des fluiden Musterproduktes P geschieht in der Anlage gemäss Figur 4 in Richtung der Schwerkraft g. Man kann natürlich auch andere, lageunabhängigere Methoden des Einfüllens, wie bspw. Einspritzen durch rückziehbare Kanülen anwenden.The fluid sample product P is filled in the system according to FIG. 4 in the direction of gravity g. Of course, other, more location-independent methods of filling, such as, for example, injection through retractable cannulas, can also be used.

Figuren 4a und 4b zeigen Musterbeutel, die in einer Anlage gemäss Figur 4 herstellbar sind, die also durch Haftstellen zwischen den beiden Folienzuschnitten formstabilisiert sind. Der Beutel gemäss Figur 4a weist bspw. vier punktförmige Haftstellen 6'' auf, welche dem Beutel die mehr oder weniger flache Form geben, indem durch diese Haftstellen 6'' ein definierter Abstand der die Aufnahmekammer bildenden Folienbahnen erzeugt wird. Figur 4b zeigt einen Beutel, dessen fluider Inhalt durch zwei linienförmige Haftstellen 6'' in parallele Kammern, die seitlich in einen gemeinsamen Raum münden, verteilt ist. Die linienförmigen Haftstellen 6'' verlaufen parallel zur Verschlussquernaht 6.FIGS. 4a and 4b show sample bags which can be produced in a system according to FIG. 4 and which are therefore dimensionally stabilized by adhesive points between the two film blanks. The bag according to FIG. 4a has, for example, four punctiform adhesive spots 6 ″, which give the bag the more or less flat shape by creating a defined distance between the film webs forming the receiving chamber through these adhesive spots 6 ″. FIG. 4b shows a bag, the fluid content of which is distributed by two line-shaped adhesion points 6 ″ in parallel chambers which open laterally into a common space. The line-shaped adhesive points 6 ″ run parallel to the sealing cross seam 6.

Musterbeutel gemäss Figur 4b, in denen die linienförmigen Haftstellen 6'' parallel zu den Längsnähten 6' verlaufen, sind herstellbar mit Presselementen wie sie in den Figuren 2 und 3 dargestellt sind, welche Presselemente formmässig und funktionsmässig entsprechend anzupassen sind.Sample bags according to FIG. 4b, in which the line-shaped adhesive points 6 ″ run parallel to the longitudinal seams 6 ′, can be produced with press elements as shown in FIGS. 2 and 3, which press elements are to be adapted in terms of shape and function accordingly.

Figur 5 zeigt einen Anlageteil 10 für kontinuierliche Konditionierung von Beutein mit fluidem Inhalt durch Erstellung von Haftstellen. Die Verschlusselemente 20 für die Längsverschlussnaht und die Verschlusselemente 4 für die Querverschlussnaht, sowie die Presselemente 5 für die Formstabilisierung bzw. Kammerbildung der Beutel sind in zwei Walzen bzw. Formmatrizen integriert. zwischen denen mittels einer Verschlusslängsnaht die Aufnahmekammer für das einzufüllende Musterprodukt gebildet wird. Die Presselemente 5 sind so beschaffen, dass entweder nahtartige Haftstellen 6'' (Figur 4b) oder punktartige Haftstellen 6'' (Figur 4a) entstehen. Die Presselemente 5 zum Konditionieren bestehen aus Kammern K, in die sich der zu konditionierende Beutel ausbreiten kann, und aus einem Mittel M mit welchem die Anker- oder Haftstellen gebildet werden. Durch gegenläufige Drehrichtung der Walzen gemäss Richtungspfeile Z wird das partiell umhüllte Musterprodukt in Pfeilrichtung z gefördert, gleichzeitig längsnahtgeschlossen, konditioniert und darauf mittels einer Querverschlussnaht verschlossen. Dazu dienen die in Achsrichtung der Walzen verlaufenden Querstege 4. Es ist auch hier offen gelassen, ob der Verschluss und die Haftstellen durch Rippenbildung oder durch eine Verschweissung oder auf eine andere Art herbeigeführt werden. Das Einfüllen des fluiden Musterproduktes P geschieht beispielsweise in Richtung der Schwerkraft g, wie das auch in Figur 3 dargestellt ist. Man kann auch hier bspw. das fluide Musterprodukt mittels rückziehbaren Kanülen gleichzeitig mit der Bildung der Anker- oder Haftstellen einspritzen. FIG. 5 shows a plant part 10 for the continuous conditioning of bags with fluid content by creating detention points. The closure elements 20 for the longitudinal closure seam and the closure elements 4 for the transverse closure seam, as well as the pressing elements 5 for the shape stabilization or chamber formation of the bags are integrated in two rollers or form dies. between which the receiving chamber for the sample product to be filled is formed by means of a longitudinal sealing seam. The pressing elements 5 are designed such that either seam-like adhesion points 6 ″ (FIG. 4b) or point-like adhesion points 6 ″ (FIG. 4a) are created. The pressing elements 5 for conditioning consist of chambers K, into which the bag to be conditioned can spread, and of a means M with which the anchor or adhesive points are formed. By reversing the direction of rotation of the rollers according to directional arrows Z, the partially encased sample product is conveyed in the direction of arrow z, at the same time closed longitudinally, conditioned and then closed by means of a transverse seam. The transverse webs 4 running in the axial direction of the rollers serve this purpose. It is also left open here whether the closure and the adhesion points are caused by ribs or by welding or brought about in some other way. The fluid sample product P is filled in, for example, in the direction of gravity g, as is also shown in FIG. 3. Here too, for example, the fluid sample product can be injected by means of retractable cannulas simultaneously with the formation of the anchor points or traps.

Figuren 6 und 6a zeigen eine weitere, beispielhafte Variante des erfindungsgemässen Verfahrens und das entsprechende Produkt. In dieser Verfahrensvariante werden die Musterbeutel nach dem Verschliessen, wenn sie noch einen quasi endlosen Beutelstrang bilden, durch Einrollen oder Einfalten und Pressen der Längskanten dieses Beutelstrangs nachgeformt. Figur 6 zeigt dazu wiederum einen sehr schematisch dargestellten Anlageteil, der ein Walzenpaar 30 (beispielsweise analog zu den Walzenpaaren der Figuren 3 und 5 aber ohne Presselemente 5 bzw. 5') zur Herstellung der Langsnähte 6' und der Quernähte 6 aufweist. Die Längsnähte 6' sind dabei nicht zu äusserst an den Folienkanten sondern von diesen beabstandet angelegt oder weisen eine entsprechend erhöhte Breite auf. Unmittelbar nach der Herstellung des Beutelstrangs werden an diesem die Längskanten durch entsprechende Führungselemente (nicht dargestellt) eingerollt oder eingefaltet und dann in einer derartigen Position beispielsweise durch ein weiteres Walzenpaar 31 gepresst. gegebenenfalls verschweisst und dadurch in dieser Position stabilisiert. Die eingerollten bzw. eingefalteten Längskanten 32 des Beutelstrangs können auch auf andere Weise stabilisiert werden, beispielsweise durch entsprechendes Einbringen eines Klebstoffes vor dem Einrollen und durch Pressen nach dem Einrollen. FIGS. 6 and 6a show a further, exemplary variant of the method according to the invention and the corresponding product. In this variant of the method, the sample bags are reshaped after being closed, if they still form a quasi-endless bag strand, by rolling or folding and pressing the longitudinal edges of this bag strand. FIG. 6 again shows a very schematically illustrated plant part, which has a pair of rollers 30 (for example analogous to the roller pairs of FIGS. 3 and 5 but without pressing elements 5 or 5 ') for producing the longitudinal seams 6' and the transverse seams 6. The longitudinal seams 6 'are not laid out to the extreme on the film edges but at a distance from them or have a correspondingly increased width. Immediately after the production of the bag strand, the longitudinal edges are rolled or folded in there by corresponding guide elements (not shown) and then pressed in such a position, for example by a further pair of rollers 31. welded if necessary and thereby stabilized in this position. The rolled-up or folded-in longitudinal edges 32 of the bag strand can also be stabilized in another way, for example by appropriately introducing an adhesive before rolling in and by pressing after rolling in.

Figur 6a zeigt einen Musterbeutel hergestellt in der Anlage gemäss Figur 6 im Schnitt parallel zu den Quernähten 6. Die Figur zeigt strichpunktiert weitere, gleiche Musterbeutel, wie sie in einem Stapel angeordnet sind. Daraus ist ersichtlich, dass die durch das Einrollen oder Einfalten entstandenen und durch das Pressen, Verschweissen und/oder Verkleben stabilisierten Längskantenbereiche 32 des Musterbeutels als Auflagestege wirken, durch die die Formwirksamkeit des immer noch im wesentlichen kissenförmigen Beutelmittelbereichs aufgehoben wird. Ferner wirken die Randbereiche 32 auch durch ihre erhöhte Steifigkeit formstabilisierend. FIG. 6a shows a sample bag produced in the system according to FIG. 6 in a section parallel to the transverse seams 6. The FIGURE shows further, identical sample bags with dash-dotted lines as they are arranged in a stack. From this it can be seen that the resulting from the curling or folding by pressing, welding and / or gluing, stabilized longitudinal edge regions 32 of the sample bag act as support webs, by means of which the shape effect of the still substantially pillow-shaped central region of the bag is canceled. Furthermore, the edge regions 32 also have a shape-stabilizing effect due to their increased rigidity.

Figuren 7 und 7a bis 7c zeigen eine weitere, beispielhafte Variante des erfindungsgemässen Verfahrens, welche Variante gegenüber dem Herstellungsverfahren gemäss dem Stande der Technik wiederum einen zusätzlichen, formgebenden Verfahrensschritt aufweist. Dabei wird an einer (1'') der Folienbahnen (Figur 7a) vor der Erstellung der Längsnähte 6' parallel zu den Längskanten der Folienbahn mit einem entsprechenden Faltwerkzeug (nicht dargestellt) je ein dachfirstförmiger Falt 70, das heisst je drei Faltlinien mit abwechselnder Faltrichtung hergestellt. Die Folienbahn 1'' mit den Falten 70 wird dann derart weiter geführt, dass durch entsprechende Reduktion der Folienbreite die Falten die gewünschte Höhe erhalten (Figur 7b). Derart geführt wird die Folienbahn 1'' mit der anderen Folienbahn 1' zusammengebracht und werden als Längsnähte beidseitig der Falten 70 Doppelnähte (dargestellt durch je zwei strichpunktierte Linien) erstellt. Dann werden die Beutel befüllt und werden die Quernähte 6 erstellt. FIGS. 7 and 7a to 7c show a further, exemplary variant of the method according to the invention, which variant in turn has an additional, shaping method step compared to the manufacturing method according to the prior art. In this case, a roof ridge-shaped fold 70, i.e. three fold lines each with an alternating folding direction, is made on one (1 '') of the film webs (FIG. 7a) before the longitudinal seams 6 'are produced parallel to the longitudinal edges of the film web with a corresponding folding tool (not shown) manufactured. The film web 1 ″ with the folds 70 is then continued in such a way that the folds are given the desired height by correspondingly reducing the film width (FIG. 7b). In this way, the film web 1 ″ is brought together with the other film web 1 ′ and 70 double seams (represented by two dash-dotted lines) are created as longitudinal seams on both sides of the folds. Then the bags are filled and the transverse seams 6 are created.

Ein Schnitt parallel zu den Quernähten durch einen fertigen Musterbeutel ist in Figur 7c dargestellt. Es ist offensichtlich, dass die durch die Doppel-Längsnähte 6' fixierten Falten 70 dieselbe Funktion übernehmen wie die durch Einrollen oder Einfalten verdickten Kantenbereiche der Beutel gemäss Figur 6a. Ein gegebenenfalls bedeutender Unterschied zur Ausführungsform gemäss Figur 6a besteht aber darin, dass die Falten 70 nach der Manipulation, die sie als Form-stabilisierendes Mittel erleichtern oder erst ermöglichen, leicht wieder zusammengedrückt werden können und dann nur noch in sehr geringem Masse verdickend wirken. Das heisst mit anderen Worten, Musterbeutel gemäss Figur 7c können problemlos und sicher auch mit hohen Verarbeitungsgeschwindigkeiten beispielsweise in Druckprodukte eingebracht werden. Ebenso einfach können die Falten 70 beim Fixieren in oder am Druckprodukt oder später durch Pressen geflächt werden, wodurch der Beutel im Druckprodukt sicher nur ein Minimum aufträgt.A section parallel to the transverse seams through a finished sample bag is shown in FIG. 7c. It is obvious that the folds 70 fixed by the double longitudinal seams 6 'perform the same function as the edge regions of the bags thickened by rolling or folding according to FIG. 6a. A possibly significant difference from the embodiment according to FIG. 6a, however, is that the folds 70 after the manipulation, which make them easier as a form-stabilizing agent or only make them possible, can be easily compressed again and then only have a very small thickening effect. In other words, that means according to sample bags Figure 7c can be introduced easily and safely even at high processing speeds, for example in printed products. The folds 70 can be flattened just as easily when they are fixed in or on the printed product or later by pressing, as a result of which the bag in the printed product is certainly only applied to a minimum.

Varianten zum Verfahren gemäss Figuren 7 und 7a bis 7c können darin bestehen, dass an beiden Folienbahnen je ein oder zwei Falten erstellt werden und darin, dass die Falten nicht dachfirstförmig sind (einen dreieckigen Querschnitt aufweisen) sondern beispielsweise einen Kreissegment-förmigen oder einen trapezförmigen Querschnitt aufweisen. Die Ausgangsbreite der beiden Folienbahnen kann gleich gross sein oder derart aufeinander abgestimmt, dass im fertigen Beutel die Langskanten der beiden Bahnen aufeinander liegen.Variants of the method according to FIGS. 7 and 7a to 7c can consist in that one or two folds are created on each of the two film webs and in that the folds are not shaped like a roof ridge (have a triangular cross-section) but, for example, a circular segment-shaped or a trapezoidal cross-section exhibit. The starting width of the two film webs can be of the same size or matched to one another such that the long edges of the two webs lie on one another in the finished bag.

Figuren 8 und 8a zeigen eine weitere, beispielhafte Variante des erfindungsgemässen Verfahrens und das damit erzeugte Produkt. Die nach dieser Verfahrensvariante hergestellten Beutel sind durch ein zusätzliches Formelement stabilisiert. Die Formelemente sind im dargestellten Falle Rahmen 33, die als quasi endlose Rahmenbahn 33' zwischen die Folienbahnen 1' und 1'' eingebracht, bei der Erstellung der Längs- und Quernähte mit den Folienbahnen verbunden und zusammen mit den Beuteln voneinander getrennt werden. Die Rahmen 33 bestehen beispielsweise aus Kunststoff (solid oder geschäumt) und sind beispielsweise 0,5 bis 1mm dick. FIGS. 8 and 8a show a further, exemplary variant of the method according to the invention and the product produced with it. The bags produced according to this process variant are stabilized by an additional shaped element. In the case shown, the shaped elements are frames 33, which are introduced as quasi-endless frame webs 33 'between the film webs 1' and 1 '', are connected to the film webs when the longitudinal and transverse seams are created, and are separated from one another together with the bags. The frames 33 are made, for example, of plastic (solid or foamed) and are, for example, 0.5 to 1 mm thick.

Damit die Musterbeutel trotz Rahmen 33 einfach geöffnet werden können. wird vorgeschlagen, die eine Folienbahn 1'' etwas breiter zu wählen als die andere Folienbahn 1', derart, dass auf einer Seite der Beutel die Folie über den Rahmen vorsteht (Bereich 34). Ferner wird vorgeschlagen, die Materialien von mindestens der vorstehenden Folie 1'' und des Rahmens derart zu wählen, dass sie bei der Erstellung der entsprechenden Langsnaht eine abschälbare Verbindung eingehen. Figur 7a zeigt einen Musterbeutel mit Rahmen 33 im Schnitt parallel zu den Quernähten. Die Figur zeigt auch den abschälbaren Folienbereich 34 in geschlossener und in geöffneter (34') Position.So that the sample bag can be easily opened despite the frame 33. It is proposed to choose a film web 1 ″ somewhat wider than the other film web 1 ′, such that the film projects over the frame on one side of the bag (area 34). It is also proposed that the materials of at least the above film 1 ″ and the frame be closed in this way choose that you create a peelable connection when creating the appropriate longitudinal seam. Figure 7a shows a sample bag with frame 33 in section parallel to the transverse seams. The figure also shows the peelable film area 34 in the closed and in the open (34 ') position.

Figur 9 illustriert eine weitere, beispielhafte Verfahrensvariante des erfindungsgemässen Verfahrens und das damit hergestellte Produkt. Die Ausgangsprodukte sind wiederum zwei Folienbahnen 1' und eine Rahmenbahn 33', wobei die Rahmenbahn nicht wie im Verfahren gemäss Figur 8 zwischen den Folienbahnen sondern neben diesen zugeführt wird. FIG. 9 illustrates a further exemplary process variant of the process according to the invention and the product produced with it. The starting products are in turn two film webs 1 'and a frame web 33', the frame web not being fed between the film webs but next to them, as in the method according to FIG. 8.

Damit die in diesem Verfahren hergestellten Musterbeutel einfach geöffnet werden können, können die Rahmen 33 beispielsweise an einer Ecke Lücken 35 aufweisen. Die Folienbahnen 1' der Musterbeutel werden beispielsweise beim Trennvorgang an den entsprechenden Stellen mit Einreisskerben versehen. Anstelle der dargestellten Lücken 35 und der entsprechenden Einreisskerben kann für ein leichtes Öffnen der Musterbeutel gemäss Figur 9 analog zum Verfahren der Figur 8 die von der Rahmenbahn 33' abgewendete Folienbahn 1' etwas breiter gewählt werden und mit der anderen Folienbahn eine abschälbare Verbindung eingehen, wodurch ein Öffnen analog zum Öffnen des Musterbeutels gemäss Figur 8a ermöglicht wird.So that the sample bags produced in this method can be opened easily, the frames 33 can have gaps 35 at one corner, for example. The film webs 1 'of the sample bags are provided with tear-in notches at the corresponding points, for example during the separation process. Instead of the gaps 35 shown and the corresponding tear-in notches, for easy opening of the sample bag according to FIG. 9, analogously to the method of FIG. 8, the film web 1 'facing away from the frame web 33' can be selected somewhat wider and a peelable connection can be made with the other film web, so that an opening analogous to the opening of the sample bag according to FIG. 8a is made possible.

Figur 10 illustriert eine weitere, beispielhafte Variante des erfindungsgemässen Verfahrens und das damit erzeugte Produkt. Als zusätzliche Formelemente werden vor oder nach dem Erstellen der Längs- und Quernähte zwei Streifen 40 in das Verfahren eingeführt, die im Bereiche der Langsnähte mit der einen der Folienbahnen 1' oder mit dem Beutelstrang verbunden, beispielsweise verschweisst oder verklebt werden. Auch eine direkte Extrusion eines geeigneten Kunststoffes auf die eine der Folienbahnen 1' oder auf den Beutelstrang zur Herstellung der Streifen 40 ist vorstellbar. Selbstverständlich können die Streifen 40 auch analog zum Verfahren, das im Zusammenhang mit den Figuren 8 und 8a beschrieben wurde, vor der Erstellung der Nähte zwischen den beiden Folienbahnen 1' eingeführt werden. FIG. 10 illustrates a further, exemplary variant of the method according to the invention and the product produced with it. Before or after the creation of the longitudinal and transverse seams, two strips 40 are introduced into the process as additional shaped elements, which strips are connected, for example welded or glued, to one of the film webs 1 'or to the bag strand in the region of the longitudinal seams. Also a direct extrusion of one suitable plastic on one of the film webs 1 'or on the bag strand for producing the strips 40 is conceivable. Of course, the strips 40 can also be introduced analogously to the method described in connection with FIGS. 8 and 8a before the seams are made between the two film webs 1 '.

Die Streifen 40 können bezüglich Material und Materialstruktur und bezüglich Querschnitt in weiten Grenzen an die verwendeten Folienbahnen, an den Inhalt der Beutel und/oder an Herstellungsparameter angepasst werden. Es sind Streifen aus Karton, Papier oder Kunststoff (solid oder geschäumt) mit beliebigen, hohlen oder kompakten Querschnitten vorstellbar.The strips 40 can be adapted in wide limits with regard to material and material structure and with respect to cross section to the film webs used, to the content of the bags and / or to production parameters. Strips of cardboard, paper or plastic (solid or foamed) with any hollow or compact cross sections are conceivable.

Figuren 11 und 12 illustrieren noch beispielhafte Verfahrensvarianten und entsprechende Produkte, in denen die Formstabilisierung realisiert wird durch je mindestens ein individuelles Formelement für jeden Beutel. Derartige Formelemente sind beispielsweise zwischen den Folienbahnen 1' und 1'' eingebrachte Ringe 41 oder im Bereiche der Beutelecken an einer Beutelaussenseite angebrachte Stützstellen 42. Die Formelemente werden beispielsweise vor der Erstellung der Längs- und Quernähte auf einer der Folienbahnen 1'' durch Aufschweissen, Ankleben oder ähnliche Verbindungsmethoden aufgebracht. FIGS. 11 and 12 illustrate exemplary process variants and corresponding products in which the shape stabilization is achieved by at least one individual shaped element for each bag. Such shaped elements are, for example, rings 41 introduced between the film webs 1 'and 1 "or support points 42 attached to the outside of the bag in the area of the bag corners. The shaped elements are, for example, welded onto one of the film webs 1" before the longitudinal and transverse seams are created, Glue or similar connection methods applied.

Die Ringe 41 als Formelemente können, wie für Rahmen (Figur 9) beschrieben, für das Öffnen der Beutel beispielsweise Lücken 43 aufweisen.As described for frames (FIG. 9), the rings 41 as shaped elements can have gaps 43 for opening the bags, for example.
