For the development of new plastics and laminates (tube materials), the highly developed, error-free tubes guaranteeing manufacturing technology for plastic tubes is added.
- Tube materials and manufacturing technology result in deformable tubes, with which a consistent quality of the packaging material from filling to emptying of the tubes is guaranteed, the tube is in addition to their function as packaging continue to be an advertising medium, the advertising shown there packaging material identification and other information relevant to the origin can enclose.
- the advertising on the tubes next to the name of the product is creatively originated, ie producer-specific, so that consumers decide on the basis of optical identification which product they are buying from which manufacturer, in the expectation of acquiring the same product of the same quality , With this expectation, this optical identification is superficial, which leads to problems for the packaging material manufacturer and / or packer in terms of its guarantee of origin, quality and quality consistency against imitators.
- Imitators can equip, for example, packaging tubes almost true to the original, under equipping here is a reproduction of a special tube shape with the same original printing understood, these replicas usually have tubes and contents, ie packaging materials, other quality than the original manufacturer. If replicas are identifiable by the consumer in terms of perceived loss of quality in terms of tubes and / or packaging material, consumers expect these copies to have been copied to the original manufacturer, a circumstance which leads to problems for the latter in terms of origin, quality and guarantee of his products ,
- the prefabricated head technique relies on the connection of a prefabricated tube head with a tube tube, in that, as a type of connection, the tube is melted by applying heat and pressure to the head, while the other type is connected to the head and tube by an injection molding process.
- the tube tube is connected to a tube head during its molding in a die, wherein the shaping can be done by forming a plasticized material portion or by injection molding.
- a method that connects the connection of prefabricated tube heads with plasticized, to be pressed material portions for the production of tubes. The developments of these manufacturing processes pursue two objectives, namely of a technical and aesthetic nature.
- the aim of the art is, on the one hand, the production of dense and mechanically strong connections, which, on the other hand, must be visually inconspicuous.
- the invention breaks with the above-outlined notion of those skilled in the art by maintaining the mechanical qualities of a head-to-tube seam, but making the join or parts thereof visible.
- the head carries a marking of other colors.
- the label is as one on the shoulder of the head formed circumferential ring, which is visible during the connection between the tube and head by pressing an annular portion of plasticized plastic other colors than the shoulder of the head and optionally the tube on the shoulder visible.
- a method for the production of tubes with the above-indicated marking, in which a prefabricated head with a tube by means of an annular portion plasticized plastic, preferably round or lenticular cross-section in which the portion along the inner periphery of an upstanding edge portion of the pipe and between or partially placed on the outer circumference of the shoulder of the head and pressed by applying the rising edge portion in the direction of a spout of the tube head by means of a mandrel and a die.

- the axial extent of the annular portion 22 depends, see Fig. 4 , According to the distance A, with the free circumferential edge 26 of the section 22 - seen from the center line of the head 12 - to support and thus an outer peripheral delimitation 27 of the label 15 forming to rest.
- the head 11 according to Fig. 2 has on its outer surface a step 29, which rotates around the outer circumference of the shoulder 14 and the spout 16 upstanding surface 30 forms the inner circumferential boundary 28.
- the transition 23 of the mandrel bevel 24 may be expedient to provide the transition 23 of the mandrel bevel 24 to the outer circumference 25 of the mandrel 20, the mandrel 20 circumferentially with a multi-chamber gradation 31.
- the Mehrcrostufung 31 (hereinafter also abbreviated as grading 31) comprises two chambers 32, 33, the first chamber 32, starting from the outer periphery of the mandrel 20 in the form of a slope in the direction of the center line M, starting in the second chamber 33, which in turn opens into the mandrel slope 24.
- the diameter of the opening closest to the center line M that is to say the circumference of the second chamber 33, is dimensioned such that it is covered by the outer circumference of the shoulder 14 of the head 12, so that the chamber 33 engages with the tube head 12 applied to the mandrel 10 the shoulder 14 forms an undercut 34 formed in the end face, while in the axial direction the first chamber 32 is in communication with the inner peripheral surface of the portion 22 of FIG Pipe 11 and the outer periphery of the shoulder 14 of the tube head 12 an open to the shoulder 14, axially to the mandrel 20 extending annular space 35 forms.
- Fig. 4 shows a relation to a parallel to the center line of a tube head 12 extending peripheral surface (not shown), as a slope 36 formed to the center line peripheral surface.
- the Fig. 2, 3 and 4 show various deformable connections between tube tube 11 and head 12.
- the compound according to Fig. 2 meets normal requirements for a connection, while the after Fig. 4 higher claims than the connection after Fig. 2 is sufficient, this because the slope 36 a larger one-sided connection surface than the parallel surface after Fig. 2 represents.
- the connection is after Fig. 3 designed to include in the connection, by the undercut 34, the inner surface (to the tube interior facing surface) of the head 12 as an addition to the surfaces of the annular space 35.

Abstract
Description
Die Erfindung betrifft einen Verpackungsbehälter, insbesondere eine Verpackungstube für pastöse Packstoffe mit einem Originalitätskennzeichen nach dem Oberbegriff des Patenanspruches 1.The invention relates to a packaging container, in particular a packaging tube for pasty packaging materials with a tamper-evident characteristic according to the preamble of claim 1.
Verpackungstuben aus Kunststoff (Kunststofftuben) haben sich neben Metalltuben zur Verpackung, Bewerbung und Andienung technischer, kosmetischer und pharmazeutischer pastöser Packstoffe weitgehend durchgesetzt. Wegen ihrer Diffusionsresistenz waren Metalltuben zur Verpackung oxidationsempfindlicher Packstoffe den Kunststofftuben überlegen. Mit der Entwicklung neuer Kunststoffe und Laminate, beispielsweise zur Herstellung von Folien für die Tubenrohrherstellung, sei es durch Extrusion oder sogenanntes Längsnahtschweissen, wurde die Ueberlegenheit der Metalltube weitgehend eliminiert, so dass Metall- und Kunststofftuben als eine verformbare Verpackung für beispielsweise oxidationsempfindliche Packstoffe als gleichwertig anzusehen sind. Zur Entwicklung neuer Kunststoffe und Laminate (Tubenwerkstoffe) tritt die hochentwickelte, fehlerfreie Tuben gewährleistende Fertigungstechnik für Kunststofftuben hinzu. Tubenwerkstoffe und Fertigungstechnik resultieren in verformbaren Tuben, mit denen eine gleichbleibende Qualität des Packstoffes von der Befüllung bis zur Entleerung der Tuben gewährleistet ist, die Tube eignet sich neben ihrer Funktion als Packmittel weiterhin als Werbeträger, wobei die dort dargestellte Werbung die Packstoffidentifikation und andere herkunftsrelevante Angaben umschliessen kann. Bei Massenartikeln, biespielsweise Zahnpasten, ist die Werbung auf den Tuben neben dem Namen des Produktes gestalterisch herkunfts- d.h. produzentenspezifisch ausgestaltet, so dass Konsumenten auf Grund einer optischen Identifikation entscheiden, welches Produkt sie von welchem Hersteller erwerben, in der Erwartung, ein gleiches Produkt gleicher Qualität zu erwerben. Mit dieser Erwartungshaltung ist diese optische Identifikation oberflächlich, was für den Packstoffhersteller und/oder Abpacker hinsichtlich seiner Gewährleistung für Herkunft, Güte und Qualitätskonstanz gegenüber Nachahmern zu Problemen führt. Nachahmer können zum Beispiel Verpackungstuben fast originalgetreu ausstatten, unter Ausstatten wird hier Nachbau einer besonderen Tubenform mit zum Original gleicher Bedruckung verstanden, wobei diese Nachbauten in der Regel Tuben und Inhalte, d.h. Packstoffe, anderer Qualität als die der Originalhersteller aufweisen. Kennzeichnen sich Nachbauten durch für den Konsumenten erkennbare Qualitätseinbussen hinsichtlich Tuben und/oder Packstoff, so rechnen die Verbraucher diese Qualitätsabstriche in Unkennntnis einen Nachbau erworben zu haben dem Originalhersteller zu, ein Umstand, der für letzteren hinsichtlich Herkunft, Güte und Garantie seiner Produkte zu Problemen führt.Plastic packaging tubes (plastic tubes) have largely prevailed alongside metal tubes for the packaging, application and delivery of technical, cosmetic and pharmaceutical pasty packaging materials. Because of their diffusion resistance, metal tubes were superior to plastic tubes for packaging oxidation-sensitive packaging materials.

Aus der
Vor diesem Hintergrund hat sich der Erfinder die Aufgabe gestellt, eine Tube mit Originalitätskennzeichen (folgend kurz auch Kennzeichen oder Kennzeichnung genannt) wobei sich die Tube mit diesem Kennzeichen auch bei oberflächlicher Betrachtung augenfällig als Original darstellt und wobei eine hohen Ansprüchen genügende Verbindung zwischen dem Tubenkopf und dem Tubenrohr gegeben ist. Diese Aufgabe wird für die Tube mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der erfindungsgemässen Tube kennzeichnen die dem Anspruch 1 folgenden Ansprüche 2 bis 5.Against this background, the inventor has taken on the task of a tube with originality mark (hereinafter also referred to as license plate or label) where the tube with this mark even when superficially obvious as an original and with a high standards sufficient connection between the tube head and given to the tube tube. This object is for the tube with the characterizing features of claim 1 solved. Advantageous embodiments of the inventive tube characterize the claims 1 to 2 following claims.
Zwei Techniken beherrschen die Technik der Herstellung von Tuben aus Kunststoffen. Die Fertigkopftechnik stellt auf die Verbindung eines vorgefertigten Tubenkopfes mit einem Tubenrohr ab, indem als eine Art der Verbindung das Rohr unter Anwendung von Wärme und Druck an den Kopf angeschmolzen, bei der anderen Art Kopf und Rohr durch einen Spritzgiessvorgang miteinander verbunden werden. Bei der Anformtechnik wird das Tubenrohr mit einem Tubenkopf während seiner Ausformung in einer Matrize verbunden, wobei die Ausformung durch Umformung einer plastifizierten Materialportion oder durch Spritzgiessen erfolgen kann. Bekannt ist auch ein Verfahren, dass zur Herstellung von Tuben die Verbindung vorgefertigter Tubenköpfe mit plastifizierten, zu verpressenden Materialportionen verbindet. Die Entwicklungen dieser Herstellverfahren verfolgen zwei Zielrichtsetzungen, und zwar technischer und aesthetischer Art. Angestrebt von der Fachwelt wird einerseits die Herstellung dichter und mechanisch belastbarer Verbindungen, die andererseits optisch unauffällig sein müssen. Zur Ausstattung einer Tube mit einem Originalitätskennzeichen bricht die Erfindung mit der vorstehend umrissenen Vorstellung der Fachwelt, indem sie die mechanischen Qualitäten einer Verbindungsnaht zwischen Kopf und Rohr beibehält, die Verbindungsnaht oder Teile davon jedoch sichtbar macht. Nach der Erfindung trägt der Kopf eine Kennzeichnung anderer Farbgebung. Bevorzugt ist die Kennzeichnung als ein auf der Schulter des Kopfes umlaufender Ring ausgebildet, der während der Verbindung zwischen Rohr und Kopf durch Verpressen einer ringförmigen Portion plastifizierten Kunststoffes anderer Farbgebung als die Schulter des Kopfes und gegebenenfalls des Tubenrohres auf der Schulter sichtbar entsteht. Vorteilhafterweise wird zur Herstellung von Tuben mit vorstehend dargestellter Kennzeichnung ein Verfahren benutzt, bei dem ein vorgefertigter Kopf mit einem Tubenrohr vermittels einer ringförmigen Portion plastifizierten Kunststoffes, vorzugsweise runden oder linsenförmigen Querschnittes, in dem die Portion entlang des inneren Umfanges eines aufragenden Randabschnittes des Rohres und zwischen oder teilweise auf dem äusseren Umfang der Schulter des Kopfes abgelegt und unter Umlage des aufragenden Randabschnittes in Richtung eines Ausgusses des Tubenkopfes vermittels eines Dornes und einer Matrize verpresst wird. Nach der Verpressung schliesst sich die ringförmige Kennzeichnung unmittelbar, d.h. an die Stirnkante des Randabschnittes an, so dass der Ring um die Länge des Randabschnittes von der Umlenkstelle beabstandet liegt. Dies hat den Vorteil, dass die Lage der Kennzeichnung entsprechend der Länge des Randabschnittes auf der äusseren Schulterfläche variiert werden kann. Damit kann die aesthetische Gesamtgestaltung beeinflusst und vermittels der Lagedifferenzierung die Identifikation von Fertigungsserien der Tuben vorgenommen werden.Two techniques dominate the technique of manufacturing plastic tubes. The prefabricated head technique relies on the connection of a prefabricated tube head with a tube tube, in that, as a type of connection, the tube is melted by applying heat and pressure to the head, while the other type is connected to the head and tube by an injection molding process. In the molding technique, the tube tube is connected to a tube head during its molding in a die, wherein the shaping can be done by forming a plasticized material portion or by injection molding. Also known is a method that connects the connection of prefabricated tube heads with plasticized, to be pressed material portions for the production of tubes. The developments of these manufacturing processes pursue two objectives, namely of a technical and aesthetic nature. The aim of the art is, on the one hand, the production of dense and mechanically strong connections, which, on the other hand, must be visually inconspicuous. To equip a tube with a tamper-evident mark, the invention breaks with the above-outlined notion of those skilled in the art by maintaining the mechanical qualities of a head-to-tube seam, but making the join or parts thereof visible. According to the invention, the head carries a marking of other colors. Preferably, the label is as one on the shoulder of the head formed circumferential ring, which is visible during the connection between the tube and head by pressing an annular portion of plasticized plastic other colors than the shoulder of the head and optionally the tube on the shoulder visible. Advantageously, a method is used for the production of tubes with the above-indicated marking, in which a prefabricated head with a tube by means of an annular portion plasticized plastic, preferably round or lenticular cross-section in which the portion along the inner periphery of an upstanding edge portion of the pipe and between or partially placed on the outer circumference of the shoulder of the head and pressed by applying the rising edge portion in the direction of a spout of the tube head by means of a mandrel and a die. After the compression, the annular marking closes immediately, ie to the front edge of the edge portion, so that the ring is spaced by the length of the edge portion of the deflection. This has the advantage that the position of the marking can be varied according to the length of the edge portion on the outer shoulder surface. Thus, the aesthetic overall design can be influenced and the identification of production series of the tubes can be carried out by means of the positional differentiation.

Der äussere Durchmesser der Schulter 14 des Kopfes 12 ist etwas kleiner als der innere Durchmesser des Rohres 11, und zwar so bemessen, dass das zur Verbindung benutzte Material während des Pressformvorganges die umlaufende Kante der Schulter 14 unter gleichzeitiger Füllung eines Ringspaltes zwischen umlaufender Kante der Schulter 14 und der inneren Oberfläche des Rohres 11 umfliessen kann. Verbunden werden Kopf 12 und Rohr 11 mit einer Materialportion 17 aus plastifiziertem Kunststoff, der so zu wählen ist, dass er sich unter Anwendung von Druck und gegebenenfalls Wärme mit dem Kunststoff des Kopfes 10 und dem Kunststoff des Rohres 11, im Falle eines Laminates mit der inneren Schicht des Rohres 11 verbindet.The outer diameter of the
Gemäss
Erfindungsgemäss kann es zweckmässig sein, den Uebergang 23 der Dornschräge 24 zum äusseren Umfang 25 des Dornes 20, den Dorn 20 umlaufend mit einer Mehrkammer-Stufung 31 zu versehen. Zweckmässigerweise umfasst die Mehrkammerstufung 31 (folgend kurz auch Stufung 31 genannt) zwei Kammern 32, 33, wobei die erste Kammer 32 vom äusseren Umfang des Dornes 20 in Form einer Schräge in Richtung auf die Mittellinie M ausgehend in die zweite Kammer 33 übergeht, die ihrerseits in die Dornschräge 24 ausmündet. Dabei ist der der Mittellinie M nächstliegende Durchmesser der Ausmündung, also der Umfang der zweiten Kammer 33, so bemessen, dass er vom äusseren Umfang der Schulter 14 des Kopfes 12 überdeckt wird, so dass die Kammer 33 bei auf den Dorn 10 aufgebrachtem Tubenkopf 12 mit der Schulter 14 eine in die Stirnfläche eingebrachte Hinterschneidung 34 bildet, während in axialer Richtung gesehen die erste Kammer 32 in Verbindung mit der inneren Umfangsfläche des Abschnittes 22 des Rohres 11 und dem äusseren Umfang der Schulter 14 des Tubenkopfes 12 einen zur Schulter 14 offenen, axial zum Dorn 20 verlaufenden Ringraum 35 bildet.

Das Verfahren zur Verbindung eines vorgefertigten Kopfes 12 an ein Rohr 11 unter Bildung der ringförmigen Verbindung auf der Schulter 14 des Kopfes 12 läuft im wesentlichen in sechs Teilschritten ab. Der erste Teilschritt besteht aus der Beladung des Dornes 20 mit einem Tubenrohr 11, in der Weise, dass ein ringförmiger Abschnitt 22 des Rohres 11 den Uebergang 23 der Dornschräge 24 zum äusseren Umfang 25 des Dornes 20 überragt. Die axiale Länge des Abschnittes 22 bemisst sich danach, welchen radialen Abstand die frei umlaufende Kante 26 des Abschnittes 22, die äussere umlaufende Abgrenzung 27 bildend, nach der Verpressung aufweisen soll. Mit Verlängerung des Abschnittes 22 steigt die Lage der äusseren umlaufenden Abgrenzung 27 in Richtung auf den Ausguss 16 auf, während bei dessen Verkürzung die Abgrenzung in Richtung auf den Uebergang 23, also in Richtung des äusseren Umfanges der Dornschräge 24 abfällt. In einem zweiten Teilschritt wird der vorgefertigte Kopf 12 auf den Dorn 20 aufgeracht, wobei dieser über die Oeffnung des Ausgusses 16 und Dornfortsatz 21 zentrisch auf dem Dorn 20 gehalten und von dem ringförmigen Abschnitt 22 umlaufen ist. In einem dritten Teilschritt wird die Materialportion 17 aus Verbindungsmaterial auf die der Dornschräge 24 abgewandten Seite der Schulter 14, d.h. der sichtbaren Aussenseite der Schulter 14 aufgebracht. Bevorzugt ist, dass die Materialportion 17 am inneren Umfang des Abschnittes 22 anliegt und an letzterem vollständig umläuft. Die Materialportion 17 besteht aus einem plastifizierten Kunststoff, der in seiner Zusammensetzung so zu wählen ist, dass er sich unter Anwendung von Druck und gegebenenfalls Wärme mit dem Kunststoff des Kopfes 12 und dem des Rohres 11, im Falles eines Lamites mit der inneren Kunststoffschicht des Rohres 11 verbindet. Die Materialportion kann vorgefertigt und eingelegt oder durch Extrusion auf die Schulter 14, vorzugsweise Ringräume 35 überdeckend aufgebracht sein. Bevorzugt sind Materialportionen 17, die ringförmig, d.h. als geschlossene Ringe ausgebildet sind und deren Querschnitt vorzugsweise kreis-, linsen- oder tropfenförmig ausgestaltet ist. Zur Erzeugung einer Kennzeichnung 15 auf der Schulter 14 hat der Kunststoff der Materialportion 17 eine Farbgebung, die sich deutlich sichtbar von der Farbe des Kunststoffes des vorgefertigten Kopfes 12 und gegebenenfalls der Farbe des Rohres 11 unterscheidet. Ein Dorn 20 beladen mit Tubenrohr 11, Tubenkopf 12 und einer Materialportion 17 fährt in einem vierten Teilschritt in die offene ringförmige Matrize 39 ein. Ist ein Innenring 40 vorgesehen, kommt die äussere Oberfläche der Schulter 14 mit dem Innenring 40 in Eingriff und schiebt diesen während der Einfahrbewegung des Dornes 20 in die Matrize 39 gegen seine Federvorspannung in die Matrize zurück. Die Verpressung und Bildung der Kennzeichnung 15 erfolgt während des fünften Verfahrensschrittes. Während dieses Schrittes wird durch Einfahren des Dornes 20 in die Matrize 39 die Materialportion 17 in Ringräume 35, Stufungen 29 und in die Kammern 32, 33 der Mehrkammerstufung 31 unter Verbindung von Kopf 12 und Rohr 11 unter Einbiegung des ringförmigen Abschnittes 20 in Richtung auf die äussere Oberfläche der Schulter 14 verpresst. Der Pressvorgang ist abgeschlossen, wenn die innere Oberfläche des Abschnittes 22 in Eingriff mit der äusseren Oberfläche der Schulter 14 gebracht ist. Während der Einbiegung wird ein Teil der Materialportion 17 durch den ringförmigen Abschnitt 22 in Richtung auf den Ausguss 16 fliessend verdrängt, bis der über die Oberfläche der Schulter verdrängte Kunststoff beispielsweise an die aufstrebende Fläche 30 der Stufung 29 oder an den äusseren Umfang des Innenringes 40 aufläuft. In Teilschritt fünf ist die Verbindung von Rohr 11 und Kopf 12 erfolgt, der ringförmige Abschnitt 22 ist vermittels des in Richtung des Ausgusses 16 verdrängten Kunststoffes der Materialportion 17 mit der Schulter 14 verbunden und es ist eine ringförmige Kennzeichnung 15 auf der Oberfläche der Schulter 14, den Ausguss 16 beabstandet umlaufend gebildet, die durch eine innere 28 und äussere umlaufende Abgrenzung 27 abgregrenzt wird. Mittel (aufstrebende Fläche 30, Innenring 40) zur Bildung der inneren umlaufenden Abgrenzung 28 sind zur präzisen Darstellung der Kennzeichnung 15 bevorzugt, möglich ist aber auch , den vor der frei umlaufenden Kante 26 des Abschnittes 22 in Richtung auf den Ausguss verdrängten Kunststoff frei auf der Schulter 14 auslaufen zu lassen. Im sechsten Teilschritt wird der Dorn 20 mit Verpackungstube 10 aus der Matrize 39 ausgefahren und die Tube 10 vom Dorn 20 abgezogen, worauf sich der Fertigungsvorgang, d.h. das Verfahren zur Herstellung einer Tube 10 mit Kennzeichnung 15 wiederholt.The method of joining a
