Description

Die Erfindung betrifft eine Tube aus Metall, insbesondere Aluminium.The invention relates to a tube made of metal, especially aluminum.

Es sind Aluminiumtuben bekannt, die regelmäßig eine Außenlackierung und einen Aufdruck aufweisen. Solche Aluminiumtuben sind zwar insofern vorteilhaft, als sie eine Sperrschicht gegen Diffusionen bilden, folglich für das Abfüllen von Füllgütern mit diffusionsfähigen Bestandteilen besonders geeignet sind, jedoch befriedigen Aluminiumtuben in ästhetischer Hinsicht selbst dann nicht, wenn sie eine bedruckte Lackschicht aufweisen. – Ferner kennt man extrudierte Kunststofftuben, die wie Aluminiumtuben einen Aufdruck aufweisen. Solche Kunststofftuben sind nahtfrei und genügen daher den ästhetischen Anforderungen, sind jedoch insofern nachteilig als sie keine Diffusionssperre bilden und folglich diffusionsfähige Füllgutbestandteile diffundieren können. – Außerdem sind Tuben aus verschweißten Verbundfolien bekannt, bei denen die Tubenhülse eine Längsschweißnaht aufweist. Zwar kann in die Verbundfolien eine diffusionsfeste Sperrfolie integriert sein, jedoch stört die Längsschweißnaht in optischer Hinsicht, so dass auch Tuben aus Verbundfolien in ästhetischer Hinsicht unbefriedigend sind.Aluminum tubes are known which regularly one exterior painting and have an imprint. Such aluminum tubes are admittedly advantageous in that as they form a barrier against diffusion, consequently for filling Products with diffusible components are particularly suitable, but satisfy aluminum tubes in aesthetic terms Not regard even if they have a printed layer of paint exhibit. - Further one knows extruded plastic tubes that unite like aluminum tubes Have imprint. Such plastic tubes are seamless and are therefore sufficient the aesthetic requirements, are disadvantageous in that they do not form a diffusion barrier and consequently diffusible Füllgutbestandteile can diffuse. - Also are Tubes made of welded Composite films are known in which the tube sleeve has a longitudinal weld. Although in the composite films have a diffusion-resistant barrier film integrated, however bothers the longitudinal weld in optically, so that tubes made of composite films in aesthetic Are unsatisfactory.

Der Erfindung liegt die Aufgabe zu Grunde, eine Tube aus Metall, insbesondere Aluminium, zu schaffen, die als von Hause aus diffusionsfeste Tube auch allen ästhetischen Anforderungen genügt.The invention is based on the object Reason to create a tube made of metal, especially aluminum, the inherently diffusion-proof tube also for all aesthetic ones Requirements are sufficient.

Zur Lösung dieser Aufgabe lehrt die Erfindung eine Metalltube und insbesondere Aluminiumtube, die durch zumindest eine nahtfreie Außenbeschichtung aus Kunststoff gekennzeichnet ist. – Die Erfindung geht von der Erkenntnis aus, dass sich auch eine Tube aus Metall oder Aluminium mit einer Außenbeschichtung aus Kunststoff versehen lässt, so dass eine solche Tube dann in ästhetischer Hinsicht den gleichen Anforderungen wie eine Kunststofftube genügt, jedoch mit dem entscheidenden Unterschied, dass sie zugleich eine Sperrschicht gegen diffusionsfähige Bestandteile bildet, so dass sich unverändert Füllgüter mit diffusionsfähigen Bestandteilen abfüllen lassen. Die erfindungsgemäße Tube kann auch eine nahtfreie Innenbeschichtung aus Kunststoff aufweisen. Die Außenbeschichtung und ggf. Innenbeschichtung bestehen vorzugsweise aus einer in die Leertube eingebrannten Pulverbeschichtung. Als Pulverbeschichtung wird vorzugsweise ein Epoxiphenolpulver eingebrannt. Die Pulverbeschichtung lässt sich unschwer mittels einer Spritzpistole im Wege einer elektrostatischen Aufladung gleichmäßig auf die Außenseite und ggf. Innenseite des Tubenkörpers aufbringen, in einem Ofen einbrennen und schließlich nach dem Trocknen auch in herkömmlicher Weise bedrucken. Wird beispielsweise ein Epoxiphenolpulver verwendet, dann handelt es sich um ein lösungsmittelfreies Pulver, welches insbesondere auch für die Innenbeschichtung und das damit kontaktierte Füllgut geeignet ist, aber auch unter Berücksichtigung der Außenbeschichtung umweltfreundlich ist. Erst nachdem die erfindungsgemäße Tube abgefüllt worden ist, wird deren kunststoffbeschichtete Tubenhülse bodenseitig in herkömmlicher Weise verschlossen.The teaches to solve this task Invention a metal tube and in particular aluminum tube, by at least a seamless outer coating is marked from plastic. - The invention is based on the Realizing that there is also a tube made of metal or aluminum with an outer coating made of plastic, so that such a tube is then more aesthetically pleasing Regarding the same requirements as a plastic tube, however with the crucial difference that they are also a barrier layer against diffusible Forms constituents so that contents with diffusible constituents remain unchanged bottling to let. The tube according to the invention can also have a seamless inner coating made of plastic. The outer coating and optionally the inner coating preferably consist of one in the Empty tube baked powder coating. As a powder coating an epoxy phenol powder is preferably baked. The powder coating let yourself easily by means of a spray gun by means of an electrostatic Charge evenly the outside and possibly the inside of the tube body apply, bake in an oven and finally after drying in conventional Print wise. For example, if an epoxy phenol powder is used, then it is a solvent-free Powder, which is also particularly suitable for interior coating and the product contacted with it is suitable, but also taking into account the outer coating is environmentally friendly. Only after the tube according to the invention bottled , the plastic-coated tube sleeve is on the bottom in conventional Closed way.

Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Es zeigen:The invention is described below one is just an embodiment illustrative drawing closer explained. Show it:

1 eine erfindungsgemäße Tube aus Aluminium in Seitenansicht vor dem Verfüllen und 1 a tube of aluminum according to the invention in side view before filling and

2 einen Querschnitt durch den Gegenstand nach 1 im Bereich der Tubenhülse. 2 a cross section through the object 1 in the area of the tube sleeve.

In den Figuren ist eine Aluminiumtube 1 dargestellt, die eine nahtfreie Außenbeschichtung 2 und nahtfreie Innenbeschichtung 3 aus Kunststoff aufweist. Die Außenbeschichtung 2 und Innenbeschichtung 3 bestehen aus einer in die Leertube eingebrannten Pulverbeschichtung aus Epoxiphenolpulver.There is an aluminum tube in the figures 1 shown that a seamless outer coating 2 and seamless interior coating 3 made of plastic. The outer coating 2 and interior coating 3 consist of a powder coating of epoxy phenol powder, which is burned into the empty tube.
