VERFAHREN ZUM SCHLIESSEN DES ENDES EINER TUBE SOWIE ANLAGE ZUR ANWENDUNG DES VERFAHRENSMETHOD FOR CLOSING THE END OF A TUBE AND PLANT FOR APPLYING THE METHOD

Den Geqenstand dieser Erfindung bildet ein Verfahren zum Schliessen des Endes einer aus Kunststoff hergestel1ten oder aus Aluminiumfolienschichten und Kunststoffschichten laminierten Tube, welche Tube zur Aufbewahrung und Dosierung von z.B. Zahnpaste oder Kosmetika benutzt wird, sowie eine Anlage zur Anwendung des Verfahrens.The object of this invention is a method for closing the end of a tube made of plastic or laminated from aluminum foil layers and plastic layers, which tube for storing and metering e.g. Toothpaste or cosmetics is used, as well as a plant for applying the method.

Man kennt heute hauptsächlih drei Typen von Tuben zur Aufbewahrung und Dosierung von Zahnpaste oder Kosmetika oder entsprechenden Mitteln. Früher waren Tuben aus Leichtmetall, besonders aus Aluminium, üblich. Bei ihnen geschah das Schliessen des Tubenendes im allgemeinen so, dass daran mehrere Falze gemacht wurden. Eine Naht dieser Art ist aber nicht sicher genug, denn es kommt oft vor, dass die Aluminiumtube im Gebrauch eben an der Naht des Tubenendes bricht.There are three main types of tubes for storing and dosing toothpaste or cosmetics or the like. In the past, tubes made of light metal, especially aluminum, were common. For them, the closing of the tube end was generally done in such a way that several folds were made on it. However, a seam of this type is not safe enough because it often happens that the aluminum tube breaks during use at the seam of the tube end.

Sehr üblich sind Kunststofftuben, in denen der Mantel qanz aus elastischem Kunststoff gebildet ist. Eine solche Tube hat den Vorteil, dass sie im Gebrauch ihre Form behält, wodurch sie, da ihr Aussehen ästhetisch bleibt, für Kosmetika der weiblichen Schönheitspflege sehr geeignet ist.Plastic tubes in which the jacket qanz is made of elastic plastic are very common. The advantage of such a tube is that it keeps its shape when in use, making it very suitable for cosmetics used in feminine beauty care because its appearance remains aesthetic.

Heute werden allgemein auch Laminattuben benutzt, in denen der - Mantel aus aufeinander laminierten Kunststoffschichten undToday, laminate tubes are generally also used, in which the - jacket made of plastic layers laminated on top of one another

Aluminiumfolienschichten besteht- Anders als eine ganz aus Kunststoff herqestellte Tube, dis Form einer Laminattube verändert sich im Gebrauch wegen der Aluminiumfolienschichten. Als Kunststoffmaterial werden im allgemeinen Polyolefine, z.B. LD- oder HD—Polyäthylen oder Polypropylen, verwendet. Das Schliessen des Endes einer Kunststoff- oder Laminattube erfolt gewöhnlich z.B. so, dass das offene Ende des im Querschnitt wesentlich kreisförmigen oder ovalen Mantels weich erwärmt und zugedrückt wird. Die gegeneinandergekommenen Seiten des Mantels ; werden dadurch zusammengesisgelt. Die Festigkeit der Naht ist dabei dieselbe wie die Einreissfestigkeit des inneren, zugesiegelten Kunststoffs. Sie kann aber nicht für ausreichend gehalten werden, da die Längsnaht des Mantels der Tube, nach neuesten Varfahren hergestellt, sogar zweimal soviel Druck aushält wie das Ende der Tube.Aluminum foil layers - Unlike a tube made entirely of plastic, the shape of a laminate tube changes in use due to the aluminum foil layers. Polyolefins, e.g. LD or HD — polyethylene or polypropylene. Closing the end of a plastic or laminate tube is usually done e.g. so that the open end of the jacket, which is essentially circular or oval in cross section, is gently warmed and pressed shut. The facing sides of the coat; are siselled together. The strength of the seam is the same as the tear resistance of the inner, sealed plastic. However, it cannot be considered sufficient, since the longitudinal seam of the jacket of the tube, manufactured according to the latest varing methods, can even withstand twice as much pressure as the end of the tube.

Die Naht des Tubenendes wird u.a. von Aromen des in der Tube befindlichen Stoffes, z.B. der Zahnpaste, abgeschwächt, die im Laufe der Zeit an der Nacht fressen. Man hat empirisch - feststellen können, dass die Festigkeit der Endnaht im halbenThe seam of the tube end is of flavors of the substance in the tube, e.g. the toothpaste, weakened, which over time eat at night. It has been empirically possible to determine that the strength of the end seam is half

Jahr auf die Hälfe der ursprünglichen Festigkeit sinkt. Es ist klar, dass solche Beobachtungen dazu Anlass gegeben haben, den 3Year drops to half the original strength. It is clear that such observations have given rise to the 3rd

Aufbau der Endnaht genauer zu untersuchen. Zum besseren Verständnis der nun gemachten Erfindung und der mit ihr erzielten Vorteile ist es angebracht, die Ursachen zu erklären, weshalb die heutige Naht nicht hält.Examine the structure of the end seam more closely. For a better understanding of the invention now made and the advantages achieved with it, it is appropriate to explain the reasons why today's seam does not hold.

Die Länge der Naht ist gewöhnlich ca. 5-iö cm. Nach dem Schliessen ist die Naht gleichmässig und ihr Querschnitt linienartig. Wenn in der Tube Druck gebildet wird, will die Naht reissen, da die Festigkeit der Naht nicht ausreicht, es zu verhindern, dass sich die Wandungen des Mantels auseinanderbewegen. Das Reissen wird im Laufe der Zeit auch von ; obenerwähnten Aromen, die an der Naht fressen, gefördert. DerThe length of the seam is usually about 5-iö cm. After closing, the seam is even and its cross-section is linear. If pressure is created in the tube, the seam will tear because the strength of the seam is insufficient to prevent the walls of the jacket from moving apart. The tearing is also over time by; above mentioned flavors that eat at the seam promoted. The

Riss wird mit ovalem Querschnitt grösser, bis in der Naht des Tubenendes eine Öffnung entsteht.The crack becomes larger with an oval cross-section until an opening is created in the seam of the tube end.

Der Zweck dieser Erfindung ist, ein Verfahren zu schaffen, mit dem das Ende einer Kunststoff— oder Laminattube so geschlossen wird, dass es grössere Beanspruchungen aushält als früher. Ausserdem ist der Zweck der Erfindung, eine Anlage zur Anwendung des Verfahrens zu schaffen. Das der Erfindung entsprechende Verfahren ist dadurch gekennzeichnet, dass das offene Ende einer zumindest an einem Ende offenen Tube flachgedrückt, gefalzt und gesiegelt wird, indem das gefalzte Ende zumindest auf der Seite, ’ wo sich die Aussenfläche des Falzes befindet, erwärmt wird und der Falz und das übrige Teil des Tubenendes gegeneinandergedrückt werden.The purpose of this invention is to provide a method of closing the end of a plastic or laminate tube so that it can withstand greater stress than before. In addition, the purpose of the invention is to create a plant for using the method. The method according to the invention is characterized in that the open end of a tube which is open at least at one end is flattened, folded and sealed by heating the folded end at least on the side 'where the outer surface of the fold is located and the fold and the rest of the end of the tube is pressed together.

Eine günstige Anwendungsform des der Erfindung entsprechenden ; Verfahrens ist dadurch gekennzeichnet, das das Ende der Tube auf beiden Seiten gesiegelt wird.A favorable form of application of the invention; The process is characterized in that the end of the tube is sealed on both sides.

Eine günstige Anwendungsforhi des der Erfindung entsprechenden Verfahrens ist dadurch gekennzeichnet, dass das offene Ende der Tube vor dem Falzen derart schräg geschnitten wird, dass die Seite des Mantels, gegen die das Ende gefalzt wird, kürzer ist, weshalb nach dem Falzen das Ende des Falzes gleichmässig ist.A favorable application form of the method according to the invention is characterized in that the open end of the tube is cut obliquely before folding in such a way that the side of the jacket against which the end is folded is shorter, which is why the end of the fold after folding is even.

Der der Erfindung entsprechend erreichte Schluss hat den Vorteil, dass der Querschnitt des Tubenendes immer linienartig bleibt und kein Reissen Vorkommen kann, da sich die entgegengesetzten Seiten des Mantels nicht auseinanderbewegen können. Die Ursache dazu ist, dass auch ausserhalb der Tube zwischen dem Falz und der Tube eine Naht entsteht. Auch Aromen des in der Tube befindlichen Stoffes können somit in den Schluss nicht eindringen. Der der Erfindung entsprechende Schluss hält eine beachtlich grössere Beanspruchung aus als bekannte Nähte, da seine Festigkeit dieselbe ist wie die Zugfestigkeit des ganzen Laminats.The conclusion reached according to the invention has the advantage that the cross section of the tube end always remains line-like and no tearing can occur, since the opposite sides of the jacket cannot move apart. The reason for this is that a seam is also created outside the tube between the fold and the tube. Even flavors of the substance in the tube cannot penetrate into the finish. The conclusion according to the invention withstands a considerably greater stress than known seams, since its strength is the same as the tensile strength of the entire laminate.

Fig. 12 eine günstige Anwendungsform der Erfindung darstellt.Fig. 12 shows a favorable embodiment of the invention.

In Figur 1 ist eine der Erfindung entsprechende Anlage teilweise geschnitten von oben gesehen dargestellt. Zur Anlage gehören Schaumgummibander 1, die die Tuben 2 in vertikaler Stellung so befördern, dass das zu schliessende Ende nach oben zeigt. Die Tuben 2 sind mit gewünschtem Material, z.B. Zahnpaste oder Entsprechendem, gefüllt. Wenn die Tuben zwischen zwei gegeneinander angeordnete Förderbänder 3 kommen, wird das Tubenende flachgedrückt, und die Förderbänder 3 befördern die • \ 8In Figure 1, a system according to the invention is shown partially in section seen from above. The system includes foam rubber bands 1, which convey the tubes 2 in a vertical position so that the end to be closed points upwards. The tubes 2 are made of the desired material, e.g. Toothpaste or equivalent filled. When the tubes come between two conveyor belts 3 arranged opposite one another, the end of the tube is flattened and the conveyor belts 3 convey the tubes

Tuben 2 weiter in eine Falzvorrichtung, die aus zwei ; hintereinander angeordneten Drehscheiben 5, 6 besteht. Die ersteTubes 2 further into a folding device consisting of two; there are turntables 5, 6 arranged one behind the other. The first

Drehscheibe 5 biegt das Ende der Tube so, dass es der vertikalen Stellung gegenüber in einen Winkel von 90 Grad kommt, und die zweite Drehscheibe 6 vervollständigt das Falzen auf die in Fig h dargestellte Weise. Nach der Falzvorrichtung ist das Ende der Tube 2 umgebogen.Turntable 5 bends the end of the tube so that it is at an angle of 90 degrees from the vertical position, and second turntable 6 completes the folding in the manner shown in FIG. After the folding device, the end of the tube 2 is bent.

Zwischen den Drehscheiben geht die Tube zwangsgesteuert in der in Fig. 5 dargestellten Stellung weiter. Dadurch wird verhindert, dass der Falz wieder gerade werde. Nach der zweiten Drehscheibe 6 geht die Tube ebenfalls zwangsgesteuert weiter in eine Siegelungsvorrichtung, die aus zwei gegeneinander befindlichen, beweglichen Siegelungsbändern 7 besteht, die so konzipiert sind, dass sie über Heisselementen 8 laufen und das Ende der Tube drücken. Um die Siegelungsbänder 7 fest in vertikaler Richtung zu halten, ist die Siegelungsvorrichtung mit auf den Innenflächen der Heisseleinente 8 versenkten Drähten 9 versehen, mit denen die Bänder 7 z.B. durch Vulkanisierung verbunden sind. Die Heisselemente 8 sind mit Wärmepatronen lö versehen, aus denen die Wärme durch die Heisselemente und Bänder an das zu siegelnde, gefalzte Ende der Tube geleitet wird. Während sich das Ende der Tube erwärmt, wird es mittels der Siegelungsbänder 5 fest zusammengepresst. Was für Nähte dadurch entstehen, wird im 9Between the turntables, the tube continues to be positively controlled in the position shown in FIG. 5. This prevents the fold from straightening out again. After the second turntable 6, the tube also continues in a force-controlled manner into a sealing device which consists of two movable sealing bands 7 which are located opposite one another and are designed such that they run over hot elements 8 and press the end of the tube. In order to hold the sealing tapes 7 firmly in the vertical direction, the sealing device is provided with wires 9 countersunk on the inner surfaces of the heating element 8, with which the tapes 7 e.g. are connected by vulcanization. The hot elements 8 are provided with heat cartridges, from which the heat is conducted through the hot elements and tapes to the folded end of the tube to be sealed. As the end of the tube heats up, it is pressed tightly together by means of the sealing strips 5. In the 9th

Zusammanhang mit Figuren 11 und 12 genauer erklärt. Der Erfindung gemäss ist es auch möglich, dass es nur ein Heisselement 8 gibt. Dabei ist es am günstigsten auf der Seite angeordnet, wo sich der Fais befindet.Connection with Figures 11 and 12 explained in more detail. According to the invention, it is also possible that there is only one hot element 8. It is best arranged on the side where the fais is located.

Ausserdem können am Ende der Anlage Abkühl- und StempelscheIben 11 angeordnet werden. Mit der Stempelscheibe kann am Schluss z.B. die Herstellungsnummer gedruckt werden.In addition, cooling and stamping discs 11 can be arranged at the end of the system. With the stamp disc you can e.g. the manufacturing number can be printed.

In Figur 10 ist ein Tubenende dargestellt, das mit dem heute üblichsten Verfahren geschlossen ist. In ihm wird die Naht 12 zwichen den Halten 13 und 14 des Mantels gebildet. Die Naht wird dadurch hergestellt, dass die Nahtstelle erwärmt und die Naht zwischen kalter« Backen fest zugedrückt wird.FIG. 10 shows a tube end which is closed using the method which is most common today. In it, the seam 12 is formed between the holders 13 and 14 of the jacket. The seam is made by heating the seam and pressing the seam tightly between cold cheeks.

In Figur 11 ist ein mit dem der Erfindung entsprechenden Verfahren hergestellter Schluss des Tubenendes dargestellt. Der Mantel 13,14 ist vor der Herstellung des Schlusses eine im Querschnitt wesentlich kreisförsnige Tube. Der Mantel ist in der Erfindung etweder ganz aus Kunststoffmaterial hergestellt oder aus aufeinander!legenden Kunststoff— und Aluminiumschichten laminiert. Als Kunststoffmaterial können am günstigsten . Polyolefine, z.B. LD- oder HD-Polyäthylen oder Polypropylen, verwendet werden. In den Figuren ist eine Tube dargestellt, 10 deren Mantel laminiert ist, wobei die Anzahl der Aluminium-Folienschichten 15 zwei ist. Die Anzahl der Aluminium-folienschichten 15 ist an sich willkürlich und beschränkt keineswegs die Erfindung. Es ist günstig, das Ende des Mantels derart ein wenig schräg zu schneiden, dass es auf der Seite kürzer ist, gegen die das Ende der Tube umgebogen werden soll. Es wird dadurch ermöglicht, dass nach dem Umbiegen die Enden der Hälften 13 und 14 des Mantels auf demselben Miveau sind. Die Naht 16 entsteht zwischen der Aussenseite der Hälfe 13 des Mantels und der Innenfläche des Falzes. Die Naht 17 entsteht innerhalb des Falzes zwischen den zwei Hälften 13 und 14 des Mantels. Wenn erforder1 ich, kann das Ende der Tube auch auf der anderen Seite gesiegelt werden, wobei zwischen den Hälften 13 und 14 des Mantels eine Mäht vor dem Falz entsteht. Das ist der Fall in den Anwendungsformbeispielen in den Figuren, Das ist aber für die Festigkeit des Endes nicht unbedingt erforderlieh.FIG. 11 shows a closure of the tube end produced using the method according to the invention. The jacket 13, 14 is a tube with a substantially circular cross section before the end is made. In the invention, the jacket is either made entirely of plastic material or laminated from layers of plastic and aluminum which are placed one on top of the other. As the plastic material can be cheapest. Polyolefins, e.g. LD or HD polyethylene or polypropylene can be used. In the figures, a tube 10 is shown, the jacket of which is laminated, the number of aluminum foil layers 15 being two. The number of aluminum foil layers 15 is arbitrary per se and in no way limits the invention. It is convenient to cut the end of the jacket a little obliquely so that it is shorter on the side against which the end of the tube is to be bent. This enables the ends of the halves 13 and 14 of the jacket to be at the same level after the bending. The seam 16 arises between the outside of the halves 13 of the jacket and the inside surface of the fold. The seam 17 arises within the fold between the two halves 13 and 14 of the jacket. If necessary, the end of the tube can also be sealed on the other side, creating a mow between the halves 13 and 14 of the jacket before the fold. This is the case in the application form examples in the figures, but this is not absolutely necessary for the strength of the end.

In Figuren 10-12 ist die Grösse des Schlusses aus zeichnungstechnischen Gründen und zwecks Klarheit der Figuren sehr übertrieben. Z.B. das Mass L der Figur 11 ist in Wirklichkeit ca. 4-5 mm und das Mass S ca. 1 mm. In natürlicher Grösse ist die untere Kante des Falzes nicht so rund, wie Figuren 11 und 12 zu verstehen geben, sondern scharf.In Figures 10-12, the size of the conclusion is very exaggerated for reasons of drawing technology and for the sake of clarity of the figures. E.g. the dimension L of FIG. 11 is in reality approx. 4-5 mm and the dimension S is approx. 1 mm. In natural size, the lower edge of the fold is not as round as shown in Figures 11 and 12, but sharp.

In Figur 12 ist eins günstige Anwendungsform der Erfindung . ’ dargestellt, in der das Ende des Mantels 13, 14 vor dem Falzen derart schräg geschnitten ist, dass nach dem Falzen und Siegeln die Aussenseite 19 der Hälfte 14 des Mantels mit der Aussenseite der Hälfte 13 des Mantels sich vereinigt» Dadurch wird ein schöneres Aussehen erreicht und die Festigkeit des Schlusses noch verbessert« Sonst ist der Aufbau des Tubenendes derselbe wie in dem in Figur 11 dargestellten Anwendungsformbeispiel, d.h. wenn auf beiden Seiten gesiegelt wird, entstehen die Nähte 16, 17 und 13.In Figure 12 is a favorable application of the invention. 'in which the end of the jacket 13, 14 is cut at an angle before the folding so that after the folding and sealing the outside 19 of the half 14 of the jacket merges with the outside of the half 13 of the jacket »This creates a more beautiful appearance achieved and the strength of the end even improved «Otherwise, the structure of the tube end is the same as in the application form example shown in Figure 11, ie when sealing on both sides, seams 16, 17 and 13 are created.
