Zusammendrückbare TubeCompressible tube

Die Erfindung Dezieht sich auf eine zusammendruckbare Tube, die aus Kunstharzen hergestellt ist.The invention relates to a collapsible tube that is made from synthetic resins.

Heutzutage sind verschiedene zusammendrückbare Tuben für Zahnpasta, medizinische Paste, pastenförmige Nahrungsmittel und dergleichen erhältlich. Bislang, wurden diese Tuben meistens aus Metall wie etwa Aluminium hergestellt und besaßen den Nachteil, daß' ihr Tubenkörper, nachdem er zusammengedrückt worden war, in'unansehnlichem Zustand, blieb, ohne seine ursprüngliche Form wieder einzunehmen. Seit kurzer Zeit sind zusammendrückbare Tuben aus Kunstharzen allgemein im Gebrauch, die nicht nur den erwähnten Nachteil der langer bekannten Metalltuoen oeseitigen, sondern auch eine Seihe von Vorteilen wie etwa geringere Herstellkosten und erhöhte Wirtschaftlichkeit mit sich Dringen. Diese Tuoen bestehen aus Kunstharzen, die genügend elastisch sind, damit der TuDenkörper in seine ursprüngliche · Form zurückkehren kann, nachdem er zusammengedrückt worden ist. Jedoch kann, während der Tuoenkörper seine ursprüngliche Form wiederNowadays there are various squeezable tubes for toothpaste, medicinal paste, pasty foods and the like are available. Until now, these tubes were mostly made of metal such as Made of aluminum and had the disadvantage that 'their tube body was in an' unsightly condition after it had been compressed, remained without returning to its original shape. Recently Compressible tubes made of synthetic resins are now in common use, which not only has the disadvantage of the long-known Metalltuoen on the side, but also a number of advantages such as lower manufacturing costs and increased profitability with it urge. These Tuoen are made of synthetic resins that are sufficient are elastic so that the door body can return to its original shape after it has been compressed. However can, while the body of the douche returns to its original shape

einnimmt, Luft in den Tubenkörper eintreten, die sowohl den Inhalt der Tube oxidieren wie auch ein Verspritzen des Inhalts verursachen kann, wenn die Tube schnell zusammengedrückt wird, da der Inhalt zusammen mit der Luft herausgedrückt wird. Außerdem kann aufgrund der gewöhnlich hohen Durchlässigkeit des Kunstharzes für gasförmigen Sauerstoff, Wasserdampf und Duftwirkstoffe sowie aufgrund einer geringen Beständigkeit gegenüber Öl der Inhalt einer solchen Tube in unerwünschter Weise physikalisch oder chemisch beeinflußt werden.occupies, air will enter the tube body, which will contain both the contents The tube will oxidize as well as splashing of the contents if the tube is squeezed quickly as the contents is pushed out along with the air. In addition, due to the usually high permeability of the synthetic resin for gaseous Oxygen, water vapor and fragrances as well as the contents of such a tube due to a low resistance to oil be influenced physically or chemically in an undesirable manner.

Ziel der Erfindung ist eine verbesserte zusammendrückbare Tube von doppelwandigem Aufbau, bei dem die innere Tube sehr öl- und wasserbeständig ist und eine äußerst geringe Durchlässigkeit für gasförmigen Sauerstoff, Wasserdampf und Duftwirkstoffe besitzt und bei dem die äußere Tube zur schützenden Aufnahme der inneren Tube ausgebildet und genügend elastisch ist, damit die äußere Tube in ihre ursprüngliche Form zurückkehren kann, nachdem sie zusammengedrückt worden ist.The aim of the invention is to provide an improved collapsible tube of double-walled construction, in which the inner tube is very oil and water resistant and extremely low permeability for gaseous Oxygen, water vapor and fragrance ingredients have and with which the outer tube is designed to receive the inner tube in a protective manner and is sufficiently elastic so that the outer tube is in its return to its original shape after being compressed.

Außerdem soll die innere Tube einer derartigen verbesserten, zusammendrückbaren Tube aus einem Blatt hergestellt sein, das aus einer Polyvinylalkoholschicht und zwei Polyäthylenschichten besteht, von denen jeweils eine auf einer der beiden Oberflächen der Polyvinylalkoholschicht aufgebracht ist.In addition, the inner tube of such an improved, compressible Tube be made from a sheet consisting of a layer of polyvinyl alcohol and two layers of polyethylene, of each of which is applied to one of the two surfaces of the polyvinyl alcohol layer.

Die innere Tuoe soll weiterhin dadurch in einer zylindrischen Form hergestellt werden, daß das Blatt umgebogen wird, wobei seine seitlichen Enden in sich überlappende Lage gebracht werden, und daß gleichzeitig ein schmelzflüssiges, wasserbeständiges Kunstharzmaterial auf die eine Endfläche des Blattes aufgeoracht wird, um zu verhindern, daß die Zwiscnenschicht aus Polyvinylalkohol dem Innalt der inneren Tuoe ausgesetzt wird.This keeps the inner tuoe in a cylindrical shape be produced that the sheet is bent over, with its lateral ends being brought into an overlapping position, and that at the same time, a molten water-resistant synthetic resin material on which one end face of the sheet is applied to prevent the polyvinyl alcohol intermediate layer from being exposed to the interior of the inner tube.

Dieses Ziel wird oei einer zusammendrück baren Tube mit einem Tubenkörper mit einem Tubenhals und einem auf dem Tuoenhals abnehmoar angebrachten Verschlußteil erfindungsgemäß dadurch erreicht, daß die Tuoe einen doppelwandigen Aufbau besitzt, wo Dei der Tubenkör-This goal is oei a compressible tube with a tube body with a tube neck and one detachable on the neck of the tube attached closure part according to the invention achieved in that the Tuoe has a double-walled structure, where Dei the Tubenkör-

Wie Fig. 1 zeigt, umfaßt der Tubenkörper 2, der er findungs gemäß ausgebildeten Tube 1 einen röhrenartigen Abschnitt 4, einen Tubenhals 7 (siehe Fig. 2), auf den eine Verschlußkappe 3 abnehmbar aufgesetzt ist, und eine Schulter 8, die sich zwischen dem röhrenartigen Abschnitt 4 und dem Tubenhals 7 befindet. Der röhrenartige Abschnitt 4 besitzt, wie aus den Fig. 2A und 2B am besten zu ersehen ist, einen doppelwandigen Aufbau, der eine innere Tube 5 und eine äußere Tube 6 umfaßt. Die innere Tube 5 und die äußere Tube 6 sind an ihren oberen Ende auf dem Umfang mit dem unteren Ende des schulterförmigen Abschnitts 8 dicht verbunden oder verschweißt, der vorzugsweise mit dem Tubenhals 7 als ein einziges Teil hergestellt ist. Die unteren Enden der inneren Tube 5 und der äußeren Tube 6 sind in der in den Fig. 2A und 2B dargestellten Weise dicht miteinander verbunden, können jedoch auch mit dem Rand eines geeigneten Bodenteils verschweißt sein (nicht dargestellt).As Fig. 1 shows, the tube body 2, which he invention according to formed tube 1 comprises a tubular portion 4, a tube neck 7 (see Fig. 2), on which a cap 3 is detachably placed, and a shoulder 8, which is between the tubular section 4 and the tube neck 7 is located. The tubular portion 4, as best seen in FIGS. 2A and 2B, has a double-walled structure comprising an inner tube 5 and an outer tube 6. The inner tube 5 and the outer tube 6 are tightly connected or welded at their upper end on the circumference to the lower end of the shoulder-shaped section 8, which is preferably manufactured with the tube neck 7 as a single part. The lower ends of the inner tube 5 and the outer tube 6 are tightly connected to one another in the manner shown in FIGS. 2A and 2B, but can also be welded to the edge of a suitable base part (not shown).

Die äußere Tu.be 6 wird vorzugsweise durch Fließpressen einer zylindrischen Hülse gleichen Darcamessers und Abschneiden von Stücken gewählter Länge hergestellt. Die äußere Tube 6 ist aus einem Material wie Polyäthylen, Polypropylen oder dergleichen hergestellt, das eine ausreichende Elastizität besitzt, damit die äußere T\ibe wieder ihre ursprüngliche Form annenmen kann, nachdem sie zusammengedrückt worden ist. Wie die Fig. 2A und 2B zeigen, befindet sich in der äußeren Tuoe 6 angrenzend an die Schulter 8 eine Öffnung 10, die aus Gründen, welche noch oescnrieben werden, eine VerbindungThe outer Tu.be 6 is preferably produced by extrusion of a cylindrical sleeve of the same Darca knife and cutting off pieces of selected length. The outer tube 6 is made of a material such as polyethylene, polypropylene or the like which has sufficient elasticity, so that the outer T \ ibe regain their original shape can annenmen, after it has been compressed. As FIGS. 2A and 2B show, there is an opening 10 in the outer sleeve 6 adjacent to the shoulder 8, which for reasons which will be explained later, a connection

zu einem zwischen der inneren Tube 5 und der äußeren Tube 6 gelegenen Baum herstellt.to one located between the inner tube 5 and the outer tube 6 Tree manufactures.

Wie Pig. 3 zeigt, wird der inneren Tube 5 eine im allgemeinen zylindrische Form gegeben, indem ein aus Schichtentbestehendes Blatt 11 gebogen wird und seine Seitenkanten 12. in überlappende Lage gebracht werden. Damit die innere Tube 5 flexibel ist und dennoch nicht wieder in ihre ursprüngliche Form zurückkehrt, nachdem sie'zusammengedrückt worden ist, besitzt das Blatt 11 eine hinreichend geringe Gesamtdicke und umfaßt in einer bevorzugten Ausführungsform ( in Fig. 4A dargestellt ) eine Polyvinylalkoholschicht 13 und zwei auf deren Oberflächen aufgebrachte Polyäthylenschichten 14» In einer weiteren Ausführungsform ( in Fig. 4B dargestellt ) ist. anstelle -der Polyvinylalkoholschicht 13 eine Aluminiumfolie 15 verwendet worden.Like Pig. 3 shows, the inner tube 5 is given a generally cylindrical shape by bending a sheet 11 made up of layers t and bringing its side edges 12 into an overlapping position. So that the inner tube 5 is flexible and yet does not return to its original shape after it has been compressed, the sheet 11 has a sufficiently small overall thickness and in a preferred embodiment (shown in FIG. 4A) comprises a polyvinyl alcohol layer 13 and two Polyethylene layers 14 applied to their surfaces »In a further embodiment (shown in FIG. 4B). Instead of the polyvinyl alcohol layer 13, an aluminum foil 15 has been used.

Bekanntlich besitzt eine Polyvinylalkoholschicht eine äußerst geringe Durchlässigkeit für gasförmigen Sauerstoff und Duftwirkstoffe und ist außerdem sehr ölbeständige. Da das Material.jedoch wasserlöslich ist, ist die Polyvinylalkoholschicht 13 auf ihren beiden Oberflächen jeweils mit einer Polyäthylenschicht 14 versehen, die sehr wasserbeständig ist.It is known that a polyvinyl alcohol layer is extremely thin Permeability for gaseous oxygen and fragrance ingredients and is also very oil-resistant. However, since the material is water-soluble is, the polyvinyl alcohol layer 13 is provided on both of its surfaces with a polyethylene layer 14 which is very water resistant.

Da also, wie aus der anhand der Figo 1 bis 4 erfolgten Beschreibung hervorgeht, die äußere Tube 6 genügend elastisch ist, um nach dem Zusammendrücken wieder ihre ursprüngliche Form anzunehmen, während im Gegensatz dazu die innere Tube 5 nach dem Zusammendrücken nicht ' in ihre ursprüngliche Form zurückkehren kann, ändert sich der röhrenartige Abschnitt 4 von dem in Fig. 2A gezeigten Zustand in den' in Fig. 2B dargestellten Zustand, wenn der Inhalt der Tube herausgedrückt wird. Die innere Tube 5 bleibt in dem in Fig. 2B gezeigten Zustand, bis weiterer Druck auf den Tubenkörper 2 ausgeübt wird0 Y/enn der Druck, der sich in dem Tubenkörper 2 aufgebaut hat, abfällt, kehrt die äußere Tube 6 von allein in ihre ursprüngliche Form zurück, und gleichzeitig tritt durch die Öffnung 10 Luft in den zwischen -der inneren Tube 5 und der-äußeren Tube 6 gebildeten Raum ein. Wie Fig. 2Ji zeigt, besitzt die Tube, auch nachdem sie zu-Since, as can be seen from the description made with reference to FIGS Can return shape, the tubular portion 4 changes from the state shown in Fig. 2A to the 'shown in Fig. 2B when the contents of the tube is pushed out. The inner tube 5 remains in which it is exerted in state of Fig. 2B to further pressure on the tube body 2 0 Y / hen the pressure that has built up in the tube body 2, falls, the outer tube 6 returns by itself to its original shape, and at the same time air enters the space formed between the inner tube 5 and the outer tube 6 through the opening 10. As Fig. 2Ji shows, the tube, even after it has been

309828/0353309828/0353

sammengedrückt worden ist, immer eine ansprechende Erscheinungsform, Da über die Aü3trittsöffnung in dem Tubenhals 7 keine Luft in die innere Tube 5 eintritt, wird ein Verspritzen des Inhalts der Tube 5 bei schnellem Zusammendrücken des Tubenkörpers 2 verhinderte Außerdem entsteht in dem zwischen der inneren Tube 5 und der äußeren Tube 6 gelegenen Raum kein Vakuum, da die Öffnung 10 vorgesehen ist. Ein weiterer Vorteil, den die Erfindung mit sich bringt, besteht darin, daß aufgrund der Polyvinylalkoholschicht der Tubeninhalt nur wenig oder praktisch gar nicht an Duft verliert und oxydiert und außerdem aufgrund der Aufbringung der Polyäthylenschichten 14 auf die Schicht 13 vor Austrocknung geschützt ist.has been squeezed, always an appealing appearance, Since no air enters the inner tube 5 via the outlet opening in the tube neck 7, the contents will splash the tube 5 prevented at rapid compression of the tube body 2 also arises in the between the inner tube 5 and the outer tube 6 located space no vacuum, since the opening 10 is provided. Another advantage that the invention has brings, is that due to the polyvinyl alcohol layer, the tube contents lose little or practically no scent at all and is oxidized and also protected from drying out due to the application of the polyethylene layers 14 to the layer 13.

Anhand der Fig. 5 bis 7 wird im folgenden näher beschrieben, auf welche Art die seitlichen Enden 12 des Blattes 11 befestigt werden, um die zylindrische innere Tube 5 auszubilden.5 to 7 will be described in more detail below on which way the lateral ends 12 of the blade 11 are attached to form the cylindrical inner tube 5.

Die sich nach Pig. 5A in überlappender Lage befindenden Seitenenden 12 des Blattes 11 sind durch elektrisches Erwärmen oder irgend ein anderes geeignetes Verfahren miteinander verbunden oder verschmolzen worden. Auf die innere Endfläche 16a des Blattes 11 ist eine geringe Menge eines geeigneten wasserbeständigen Materials 17, etwa Polyäthylen, in schmelzflüssigem Zustand aufgebracht worden, um zu vernindern, daß das Ende der wasserlöslichen Polyvinylalkoholschicht 13 dem Inhalt der inneren Tube 5 ausgesetzt ist. Falls gewünscht, kann ein solches wasserbeständiges Material 17 auch auf die äußere Endfläche 16b des Blattes 11 aufgebracht werden, wie dies in Fig. 5B gezeigt ist.According to Pig. 5A overlapping page ends 12 of the sheet 11 are bonded together or by electrical heating or any other suitable method been merged. On the inner end surface 16a of the sheet 11 a small amount of a suitable water-resistant material 17, such as polyethylene, has been applied in a molten state, to prevent the end of the water-soluble polyvinyl alcohol layer 13 from being exposed to the contents of the inner tube 5. If desired, such a water-resistant material 17 can also be applied to the outer end surface 16b of the sheet 11, as shown in Fig. 5B.

In Fig» 6 ist ein typiscnes Verfahren zum Verformen des aus Schichten bestenenden Blattes 11 zu einer gewöhnlich zylindrischen Form scnematisch dargestellt. Das Blatt 11 wird von einer liagazinrolle 18 über eine Führungswalze 19 einer Vorrichtung 20 zum Herstellen eines Ronrkörpers zugefünrt. Die Vorrichtung 20 weist eine im allgemeinen in waagerechter Lage angeordnete zylindrische Stange 21 auf, deren Durchmesser etwas geringer ist als der Innendruchmesser der inneren Tube 5. In der Nähe des vorderen Endes der zylindri-In Fig. 6 is a typical method of deforming the layer best sheet 11 to a generally cylindrical shape shown schematically. The sheet 11 is from a liagazinrolle 18 via a guide roller 19 of a device 20 for manufacturing a circular body. The device 20 has a cylindrical rod 21 arranged in a generally horizontal position whose diameter is slightly smaller than the inner diameter of the inner tube 5. Near the front end of the cylindri-

Wie Fig.» 7 zeigt, ist die Düse 25 so positioniert, daß sich ihre Mindung an einer unmittelbar oberhalb der einen Endfläche 16 des rinneriförmigen Blattes 11 gelegenen Stelle befindet, um das Material 17 auf sie aufzubringen. Falls gewünscht, kann die Do.se 23 mittels einer in waagerechter Eichtung arbeitenden Einrichtung in. eine Lage verschoben werden, in der das Material 17 auf die andere Endflache 16 des Blattes 11 aufgebracht werden kann, wie es durch die strichpunktierten Linien in Fig. 7, dargestellt ist.See rod 21 a U-shaped guide part 22 is arranged, which, in cooperation with the cylindrical rod 21, deforms the sheet 11 into a groove o In the vicinity of the U-shaped guide part 22, a nozzle 23 is arranged in the feed direction of the sheet 11 which the water-resistant material 17, which is kept in the molten state, leaks. Like Fig. " 7 shows, the nozzle 25 is positioned so that its orifice is at a location immediately above the one end surface 16 of the gutter-shaped blade 11 for applying the material 17 to it. If desired, the can 23 can be moved by means of a device operating in the horizontal direction into a position in which the material 17 can be applied to the other end surface 16 of the sheet 11, as indicated by the dash-dotted lines in FIG is shown.

Stromab der Düse 23 befindet sich eine elektrische Heizeinrichtung 24, um die sich überlappenden Abschnitte 12 des Blattes 11 für ihre Verschmelzung zu erwärmen. Der auf diese Weise hergestellte röhrenartige Körper wird an seinen sich überlappenden Abschnitten 12 durch eine Walze 25 gedruckt und anschließend durch eine Kühlwalze 26 abgekühlt. Der röhrenartige Körper wird außerdem zwischen einem Transportwalzenpaar 27 geführt, durch das seine Durchlaufgeschwindigkeit durch die Vorrichtung 20 reguliert wird. Der röhrenförmige Körper wird, was hier nicht dargestellt ist, anschließend mittels einer geeigneten Einrichtung in Abschnitte von gewählter Länge geschnitten.. Downstream of the nozzle 23 is an electrical heater 24 to heat the overlapping portions 12 of the sheet 11 to fuse them. The tubular body produced in this way is printed at its overlapping portions 12 by a roller 25 and then cooled by a cooling roller 26. The tubular body is also guided between a pair of transport rollers 27, by means of which its speed through the device 20 is regulated. The tubular body, which is not shown here, is then cut into sections of selected length by means of a suitable device.
