Abstract

The tube has a peg-shaped neck extension (3) at its upper end, which contains a predetermined breaking point (4). The neck extension (3) is generally positioned under the removable protective cap (7). A short socket (9) is formed on the upper side of the cap (7) in an axial direction, the interior diameter of which is slightly greater than the diameter of the neck extension (3). The inner surface of this socket (9) and the outer surface of the neck extension (3) are provided with corresponding notch flanges (5) or notch grooves (10), such that the cap (7) and the neck extension (3) are non-positively connected to each other when rotated about the longitudinal axis, when the cap (7) with the socket (9) is positioned on the peg-shaped neck extension (3). If the cap (7) is rotated in this position about the longitudinal axis with slight pressure simultaneously exerted then the peg-shaped neck extension (3) is sheared off at the predetermined breaking point (4) and the tube is thereby opened. The cap (7) thus acts as protective cap on the one hand and as a tool for opening the tube on the other hand.

Description

Die Erfindung bezieht sich auf einen tubenförmigen Behälter für ein pastöses oder flüssiges Produkt mit einem als Tubenverschluß ausgebildeten stiftförmigen, abbrechbaren Halsfortsatz, der durch eine abnehmbare Kappe abgedeckt ist. Sofern derartige Tuben als Packmittel für pharmazeutische Produkte (Salben oder Lösungen) verwendet werden, muß dafür Sorge getragen werden, daß der Tubenhals beim Öffnen der Tube nach Möglichkeit keimfrei bleibt. In dem deutschen Patent 2 653 993 wird ein Behälter mit einem abbrechbaren Verschluß beschrieben, dessen Kopfstück besonders gestaltet ist und dadurch beim öffnen gegen Verschmutzen und Ansetzen von Keimen gesichert ist.The invention relates to a tube-shaped container for a pasty or liquid product with a pin-shaped, breakable neck extension designed as a tube closure, which is covered by a removable cap. If such tubes are used as packaging for pharmaceutical products (ointments or solutions), care must be taken to ensure that the tube neck remains aseptic when possible when the tube is opened. German patent 2,653,993 describes a container with a breakable closure, the head piece of which is specially designed and is thus secured against soiling and the accumulation of germs when opened.

Eine andere Anforderung, die vor allem bei Packmitteln gestellt wird, deren Inhalt gesundheitsschädliche Stoffe enthält, betrifft das Problem der Kindersicherheit. Dies bedeutet, daß durch zusätzliche konstruktive Maßnahmen das Öffnen der Packung bewußt erschwert wird, so daß Kinder nicht mehr ohne weiteres in der Lage sind, die Packung zu öffnen.Another requirement, which is particularly important for packaging whose content contains substances harmful to health, concerns the problem of child safety. This means that the opening of the package is deliberately made more difficult by additional constructive measures, so that children are no longer able to open the package easily.

Hier setzt die Erfindung an. Es liegt die Aufgabe zugrunde, einen tubenförmigen Behälter mit einem speziellen Verschluß zu schaffen, der einerseits vom Verbraucher ohne äußere Hilfsmittel geöffnet werden kann und andererseits wiederum so kompliziert ausgebildet ist, daß ein unbeabsichtigtes oder spielerisches Öffnen der Tube im allgemeinen nicht möglich ist.This is where the invention comes in. It is the object of a tube-shaped container with a To create a special closure that can be opened by the consumer on the one hand without external aids and on the other hand is so complicated that an unintentional or playful opening of the tube is generally not possible.

Diese Aufgabe wird bei einem tubenförmigen Behälter mit einem als Tubenverschluß ausgebildeten stiftförmigen, abbrechbaren und mit einer Kappe abgedeckten Halsfortsatz erfindungsgemäß dadurch gelöst, daß auf der Außenseite der Kappe mittig und in axialer Richtung ein Rohrstück angeformt ist, dessen Durchmesser geringfügig größer ist als der Durchmesser des Halsfortsatzes. Außerdem sind das Rohrstück an seiner Innenseite und der Halsfortsatz an seiner Außenseite mit Raststegen bzw. -rillen versehen, so daß Kappe und Halsfortsatz bezüglich einer Drehung um die Längsachse kraftschlüssig miteinander verbunden sind, wenn die Kappe zum Öffnen des Behälters um 180° gedreht und mit dem Rohrstück über den Halsfortsatz geschoben wird. Zweckmäßig schließt die Kappe bündig mit dem Rohrstück ab; d. h. die Kappe ist bis zum Ende des Rohrstückes verlängert.This object is achieved according to the invention in a tubular container with a pin-shaped, breakable neck extension designed as a tube closure and covered with a cap in that a tube piece is formed on the outside of the cap in the middle and in the axial direction, the diameter of which is slightly larger than the diameter of the Cervical process. In addition, the tube piece on its inside and the neck extension on its outside are provided with locking webs or grooves, so that the cap and neck extension are non-positively connected with respect to a rotation about the longitudinal axis when the cap is rotated through 180 ° to open the container and with the tube is pushed over the neck process. The cap expediently closes flush with the pipe section; d. H. the cap is extended to the end of the pipe section.

Gemäß einer bevorzugten Ausführung ist in Höhe des Rohrstückes zwischen der Außenwand der Kappe und dem Rohrstück ein Ringspalt vorhanden und am Tubenhals ein Kreissteg angeordnet, dessen Durchmesser dem Ringspaltdurchmesser und dessen Tiefe etwa der Länge des Halsfortsatzes entspricht.According to a preferred embodiment, an annular gap is present at the height of the pipe section between the outer wall of the cap and the pipe section and a circular web is arranged on the tube neck, the diameter of which corresponds to the ring gap diameter and the depth of which corresponds approximately to the length of the neck extension.

Durch diese Maßnahmen wird erreicht, daß der stiftförmige Halsfortsatz nicht ohne weiteres mit den Fingern abzubrechen ist. Zum öffnen muß vielmehr die Kappe erst abgenommen, um 180° gedreht und mit dem Rohrstück über den Halsfortsatz geschoben werden. Durch eine anschließende Drehbewegung und durch einen gleichzeitig ausgeübten leichten axialen Druck auf die Kappe wird der stiftförmige Halsfortsatz abgeschert. Damit liegt die Tubenöffnung frei, so daß der Inhalt entnommen werden kann. Der Grundgedanke des Verschlusses liegt also darin, daß die Kappe als Werkzeug zum Öffnen der Tube benutzt wird.These measures ensure that the pin-shaped neck process is not easily broken off with the fingers. Rather, to open the cap must first be removed, turned through 180 ° and pushed with the pipe piece over the neck extension. The pin-shaped neck extension is sheared off by a subsequent rotary movement and by a slight axial pressure exerted on the cap at the same time. This exposes the tube opening so that the contents can be removed. The basic idea of the closure is therefore that the cap is used as a tool for opening the tube.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben.The invention is described in more detail below with reference to an embodiment shown in the drawing.

Es zeigen:

  • Fig. l das Tubenkopfstück mit aufgesetzter Kappe in verschlossenem Zustand, wie die Tube vom Hersteller angeliefert wird und
  • Fig. 2 das Öffnen der Tube mittels der verkehrt herum aufgesetzten Kappe.
Show it:
  • Fig. L the tube head piece with attached cap in the closed state, as the tube is supplied by the manufacturer and
  • Fig. 2 opening the tube by means of the cap placed upside down.

Gemäß Fig. 1 besitzt die Tube 1 einen konischen Hals 2, an dessen Ende ein stiftförmiger Halsfortsatz 3 angeformt ist. An der Verbindung des Halsfortsatzes 3 zum Tubenhals 2 befindet sich eine Sollbruchstelle 4. Das zylindrische Halsstück 3 ist an seiner Mantelfläche nach Art einer Riffelung mit Längsstegen 5 versehen. An der Oberseite des Tubenhalses 2 ist ein kreisförmiger Steg 6 angeordnet. Der Kreissteg 6 ist mindestens so hoch wie der Halsfortsatz 3; d. h. der Halsfortsatz 3 ist in der durch den Kreissteg 6 gebildeten Mulde versenkt. Der Durchmesser des Kreissteges 6 und die Höhe des Halsfortsatzes 5,betragen nur wenige Millimeter, so daß es praktisch unmöglich ist, den Halsfortsatz 3 mit den Fingern abzubrechen.1, the tube 1 has a conical neck 2, at the end of which a pin-shaped neck extension 3 is formed. At the connection of the neck extension 3 to the tube neck 2 there is a predetermined breaking point 4. The cylindrical neck piece 3 is provided on its lateral surface in the manner of a corrugation with longitudinal webs 5. At the top of the tube neck 2 is a circular miger web 6 arranged. The circular web 6 is at least as high as the neck extension 3; that is, the neck extension 3 is sunk in the trough formed by the circular web 6. The diameter of the circular web 6 and the height of the neck extension 5 are only a few millimeters, so that it is practically impossible to break off the neck extension 3 with the fingers.

Über den Tubenhals 2 ist die Kappe 7 geschoben, die eine dem Tubenhals 2 angepaßte konische Innenkontur besitzt. Am Tubenhals 2 und an der Kappe 7 sind Verriegelungselemente 8 angebracht, damit die Kappe 7 nicht ohne weiteres abgezogen werden kann. Im übrigen sind die Toleranzen der konischen Konturen nicht kritisch, da zwischen Tubenhals 2 und Kappe 7 ein gewisses Spiel verbleiben kann und an dieser Stelle kein dichtender Abschluß erforderlich ist.The cap 7 is pushed over the tube neck 2 and has a conical inner contour adapted to the tube neck 2. Locking elements 8 are attached to the tube neck 2 and the cap 7 so that the cap 7 cannot be removed easily. Moreover, the tolerances of the conical contours are not critical, since a certain amount of play can remain between the tube neck 2 and the cap 7 and no sealing closure is required at this point.

An der Oberseite der Kappe 7 ist axial ein kurzes Rohrstück 9 angeformt, dessen lichte Weite geringfügig größer ist als der Durchmesser des Halsfortsatzes 3. Die Differenz der Durchmesser beträgt z. B. 0,1 bis 0,01 mm. Die Länge des Rohrstückes 9 stimmt annähernd mit der Länge des Halsfortsatzes 3 überein. Die Innenfläche des Rohrstückes ist mit Längsrillen 10 versehen, die nach Zahl und Dimensionierung den Längsstegen 5 am Halsfortsatz 3 entsprechen. Die Außenwand der Kappe 7 ist bis in Höhe des Rohrstückes 9 hochgezogen; d. h. die Kappe 7 schließt bündig mit dem Rohrstück 9 ab. Zwischen dem Rohrstück 9 und der Außenwand der Kappe verbleibt an der Oberseite ein ringförmiger Spalt 11, dessen Durchmesser ungefähr mit dem Durchmesser des Kreissteges 6 am Tubenhals 2 übereinstimmt. Desgleichen entspricht die Tiefe des Ringspaltes 11 der Höhe des Kreissteges 6.On the top of the cap 7, a short tube piece 9 is formed axially, the clear width of which is slightly larger than the diameter of the cervical process 3. The difference in diameter is, for. B. 0.1 to 0.01 mm. The length of the pipe section 9 corresponds approximately to the length of the neck extension 3. The inner surface of the tube piece is provided with longitudinal grooves 10, which correspond to the number and dimension of the longitudinal webs 5 on the neck extension 3. The outer wall of the cap 7 is pulled up to the height of the pipe section 9; ie the cap 7 is flush with the pipe section 9. Between the pipe section 9 and the outer wall of the cap, an annular gap 11 remains on the upper side, the diameter of which approximately coincides with the diameter of the circular web 6 on the tube neck 2 agrees. Likewise, the depth of the annular gap 11 corresponds to the height of the circular web 6.

Die Querausdehnung des Kreissteges 6 und des Ringspaltes 11 sind so bemessen, daß der Kreissteg 6 mit Spiel in den Ringspalt 11 paßt, wenn, wie in Fig. 2 gezeigt, die Kappe 7 mit ihrer Oberseite auf den Tubenhals 2 aufgesetzt wird. Gemäß Fig. 2 wird also die Kappe 7 vom Tubenhals 2 abgezogen, um 180° gedreht und mit dem Rohrstück 9 über den Halsfortsatz 3 geschoben. Dabei schiebt sich auch der Kreissteg 6 in den Ringspalt 11. Die Längsstege 5 am Halsfortsatz 3 greifen hierbei formschlüssig in die Ringsrillen 10 des Rohrstückes 9 ein, so daß die Kappe 7 in der Stellung nach Fig. 2 nicht um die Längsachse gedreht werden kann, ohne gleichzeitig eine Torsionskraft auf den Halsfortsatz 3 auszuüben. Somit ist die Kappe 7 als Werkzeug ausgebildet, mit dem ein Drehmoment auf den Halsfortsatz 5 und - bei entsprechender Dimensionierung der Länge des Rohrstückes 9 - auch ein axialer Druck auf den Halsfortsatz 3 ausgeübt werden kann. Beim Überschreiten eines durch die Sollbruchstelle 4 vorgegebenen Grenzwertes wird der Halsfortsatz 3 abgeschert, so daß die Tubenöffnung freigegeben wird. Der Tubeninhalt kann dann in üblicher Weise entnommen werden.The transverse extent of the circular web 6 and the annular gap 11 are dimensioned such that the circular web 6 fits into the annular gap 11 with play when, as shown in FIG. 2, the top 7 of the cap 7 is placed on the tube neck 2. According to FIG. 2, the cap 7 is pulled off the tube neck 2, rotated through 180 ° and pushed with the pipe section 9 over the neck extension 3. The circular web 6 also pushes into the annular gap 11. The longitudinal webs 5 on the neck extension 3 engage here in a form-fitting manner in the annular grooves 10 of the tubular piece 9, so that the cap 7 in the position according to FIG. 2 cannot be rotated about the longitudinal axis, without simultaneously exerting a torsional force on the cervical process 3. Thus, the cap 7 is designed as a tool with which a torque can be exerted on the neck extension 5 and - with appropriate dimensioning of the length of the tube piece 9 - also an axial pressure on the neck extension 3. When a limit value predetermined by the predetermined breaking point 4 is exceeded, the neck extension 3 is sheared off, so that the tube opening is released. The contents of the tube can then be removed in the usual way.

Es leuchtet ein, daß aufgrund dieser konstruktiven Maßnahmen die Tube nicht mehr in der gewohnten Weise zu öffnen ist. Vielmehr sind dazu 4 Schritte (Abnehmen der Kappe 7 - Drehen der Kappe 7 um 180° - Wiederaufsetzen der Kappe 7 auf den Tubenhals - Abscheren des Halsfortsatzes 3 ) erforderlich. Damit ist eine gewisse Sicherheit gegeben, daß der Verschluß nicht unbeabsichtigt oder spielerisch von Kindern geöffnet werden kann. Der neue Verschluß ist insbesondere für Tubenpackungen zur einmaligen Verwendung konzipiert.It is obvious that due to these constructive measures the tube can no longer be opened in the usual way. Rather, 4 steps are required (removing the cap 7 - rotating the cap 7 through 180 ° - replacing the cap 7 on the tube neck - shearing off the neck extension 3). So that's one given certainty that the closure cannot be opened accidentally or playfully by children. The new closure is especially designed for single-use tube packs.

Ein weiterer Vorteil besteht darin, daß der Verschluß konstruktiv einfach und daher spritzgußfreundlich ist. Als Material kann z. B. Polypropylen verwendet werden, das mit entsprechend gestalteten Spritzgußwerkzeugen verarbeitet wird.Another advantage is that the closure is structurally simple and therefore injection molding friendly. As a material z. B. polypropylene can be used, which is processed with appropriately designed injection molding tools.
