Definitions
- the present invention relates to a closure for tubes according to the preamble of claim 1.
- Closures or caps with tamper-evident protection for tubes or similar containers are well known, e.g. from EP-A-0 460 557, EP-A-0 459 941.
- tube closures are known which do not have to be completely unscrewed or pulled off in order to enable the contents of the tube to be expressed.
- the closure which has a hole in the middle, is turned one or more turns. The edge of the hole mentioned stands out from a pin which closes it in the screwed state. This frees up an annular gap through which the contents of the tube, or of the container in general, run out or can be actively expressed.
- a rotatable closure for a litter box is known.
- a large number of scatter holes in the lid of the closure which are arranged on a circle, are closed by an equal number of coinciding knobs of the same arrangement. These knobs are arranged on projections of the inner wall surface of the container-side part of the closure.
- the lid is rotated about its axis of rotation; as a result, the scatter holes move away from the knobs mentioned and the spreading material can be shaken out of the holes.
- the object that is to be achieved with the present invention is to provide a closure for tubes or soft plastic bottles, which does not have to be completely unscrewed to enable the contents to be expressed, and which can be easily secured with a tamper-evident device can be connected.
- the first embodiment is shown in Fig. 1a, b in section, in Fig. 1b in a plan view.
- a tube body 1 carries - connected to it, for example, by welding - a shoulder 2 which narrows upward to form a tube neck 7.
- This has an annular bead 4.
- a closure cap 3 is divided into two concentric cylindrical parts 8, 9 and an end plate 10, the inner cylindrical part 9 fitting onto the tube neck 7 with little play and having an annular groove 5 corresponding to the annular bead 4.
- Ring bead 4 and ring groove 5 are shaped such that the closure cap 3 can be pushed over the tube neck 7 by stretching the inner cylindrical part 9, but that the closure cap 3 can no longer be removed without destroying it.
- the tube neck 7 is closed except for an eccentrically lying opening 6.
- the opening 6 is tightly closed by the end plate 10.
- the outer structure of the closure cap 3 does not need to have the shape shown, but can be flat, convex or concave with respect to the end plate 10; furthermore, the transition from the end plate 10 to the outer cylindrical part 8 can be a gradual one; nor does the outer cylindrical part 8 really have to have a cylindrical shape: polygonal designs are also conceivable and form a question of taste, not a technical one.
- a downwardly closed, upwardly open cylinder 11 is formed, which contains a ball 13 pressed up by a helical spring 12.
- the ball 13 is movable with play in the cylinder 11 and closes - in the position according to FIGS. 1a, b - an opening 14 in the closure cap 3, which opening 14 is shaped like a segment of a spherical shell.
- the closure cap 3 is rotated by the angle ⁇ .
- the end plate 10 presses the ball 13 downward against the resistance of the coil spring 12; the opening 14 in the cap 3 comes to rest over the opening 6: the contents of the tube can be removed.
- the ball 13 closes the opening 14 again, and any remnants of the tube contents can be removed from the ball with a finger.
- the restriction of the rotatability of the closure cap 3 to the intended angle ⁇ is brought about by the interaction of a cam 15 which is integrally formed on the shoulder 2 and a lateral recess 16 in the outer cylindrical part 8 of the closure cap 3.
- the recess 16 is therefore so wide that, taking into account the width of the cam 15, it permits the screw cap 3 to be rotated by the angle ⁇ .
- the parts designated 17 to 20 are explained in connection with FIG. 4.
- FIG. 4 shows a perspective phantom representation of the exemplary embodiment according to FIGS. 1a, b.
- a ring 17 is inserted, which is connected via a strip 19 and a predetermined breaking point 18 to a tab located outside the closure cap 3.
- the predetermined breaking point 18 lies directly within the recess 16.
- the dimensions of the flap 20 are greater than the width of the recess 16.
- the thickness of the material of this tamper-evident device, consisting of the parts labeled 17 to 20, preferably corresponds to the height of the recess 16.
- the Tab 20 can be provided with price, product information and expiry date, for example. Without tearing the predetermined breaking point 18, the closure cap 3 cannot be rotated and the closure cap 3 otherwise only be blasted off the tube with the use of force and its destruction.
- the design described has the effect that the strip 19 does not hinder the rotation of the closure cap 3 after the flap 20 has been torn off - that is to say after the tamper-proof has been breached. Furthermore, it is not possible to put the tab 20 back into the recess 16 in order to simulate originality.
- the ring 17 is so large that the predetermined breaking point 18 comes to lie between the outer edge of the ring 17 and the tab 20, the strip 19 being omitted.
- the tamper-evident device shown in FIG. 2 is preferably made of cardboard. This enables cost-effective production, problem-free printing and easy integration during the closing process.
- Fig. 2 shows a second embodiment.
- a ball part 21 which is connected via an annular spring joint 22 to the end of the tube neck 7 and is produced in the same injection mold.
- the remaining parts and designs correspond to those of FIG. 1.
- FIG. 3 a, b Another embodiment is shown in Fig. 3 a, b.
- the front end of the tube neck 7, with undiminished wall thickness has an attachment in the form of a spherical segment 23.
- the end plate 10 is made thinner in a central region 24 than the rest of the end plate 10. If the closure cap 3 is rotated, the end plate 10 gives up in the region 24 until the spherical segment 23 into a spherical segment-shaped bulge 25 in the region 24 of the end plate 10 snaps into place.
- This bulge 25 is also offset by an angle ⁇ with respect to the opening 14 in the closure cap 3, so that the ball segment 23 engages in the bulge 25 in the same position of the closure cap 3 as the opening 6 in the tube neck 7 through the opening 14 in the cap 3rd
- the tube which is provided with the closure according to the invention remains essentially closed.
- the small remainder of the tube content, which remains in the opening 14 in the closure cap 3 when the expressed quantum has been removed, for example with a finger, is removed by the ball 13, the spherical segment 23 or the spherical part 21 after the closure cap 3 has been turned back Opening 14 pushed out, and can be wiped off.
- the tube closure according to the invention is suitable for any purpose or content.
Abstract
Description
Die vorliegende Erfindung betrifft einen Verschluss für Tuben nach dem Oberbegriff des Patentanspruches 1. Verschlüsse oder Verschlusskappen mit Originalitätssicherung für Tuben oder ähnliche Behälter sind viele bekannt, so z.B. aus EP-A-0 460 557, EP-A-0 459 941. Ferner sind Tubenverschlüsse bekannt, die nicht völlig abgeschraubt oder abgezogen werden müssen, um das Ausdrücken des Tubeninhalts zu ermöglichen. Bei solchen bekannten Lösungen wird der Verschluss, der in der Mitte ein Loch aufweist, eine oder mehrere Umdrehungen aufgedreht. Dabei hebt sich der Rand des genannten Loches von einem Stift ab, der es im verschraubten Zustande verschliesst. Dabei wird ein Ringspalt frei, durch welchen der Inhalt der Tube, oder des Behälters allgemein, ausläuft oder aktiv ausgedrückt werden kann.The present invention relates to a closure for tubes according to the preamble of
Sollen einer Tube nur kleine Quantitäten entnommen werden, so hat sich diese Lösung nicht durchzusetzen vermocht, da sich bei einer Salbe oder Crème beim Austritt aus einer Ringspaltöffnung ein Schlauch bildet, der wenig formstabil ist und daher keinen sicheren Rückschluss auf die ausgetretene Menge zulässt.If only small quantities are to be removed from a tube, this solution has not been able to assert itself, since in the case of an ointment or cream, a tube forms when it emerges from an annular gap opening which is not very dimensionally stable and therefore does not allow a reliable conclusion to be drawn about the quantity that has escaped.
Der Nachteil, den die meisten bekannten Originalitätsverschlüsse aufweisen, (die zwei genannten Europäischen Patentanmeldungen stehen stellvertretend für eine grosse Zahl ähnlicher Lösungen) liegt hauptsächlich in ihrer räumlichen Komplexität. Entweder sind Sollbruchstellen teils sehr komplizierter Natur vorgesehen, teils sind Originalitäts-Bänder zu zerreissen oder zu dehnen, die verlangen, dass der Verschluss aus mehreren komplizierten Teilen zusammengesetzt werden muss. Dies macht entweder mehrere oder sehr komplizierte Spritzformen erforderlich, die sich verteuernd auf das Produkt auswirken.The disadvantage that most known tamper-evident seals have (the two European patent applications mentioned represent a large number of similar solutions) is mainly due to their spatial complexity. Either predetermined breaking points are provided, in some cases of a very complicated nature, and in some cases originality tapes have to be torn or stretched, which require that the closure must be composed of several complicated parts. This requires either several or very complicated injection molds, which make the product more expensive.
Aus FR-A1-1 548 054 ist ein drehbarer Verschluss für eine Streudose bekannt. Dabei wird eine Vielzahl von Streulöchern im Deckel des Verschlusses, die auf einem Kreis angeordnet sind, von einer gleichen Zahl von koinzidierenden Noppen gleicher Anordnung verschlossen. Diese Noppen sind auf Auskragungen der inneren Wandfläche des behälterseitigen Teiles des Verschlusses angeordnet. Zum Oeffnen des Verschlusses wird der Deckel um seine Rotationsachse gedreht; dadurch verschieben sich die Streulöcher von den genannten Noppen weg, und das Streugut kann aus den Löchern herausgeschüttelt werden.From FR-A1-1 548 054 a rotatable closure for a litter box is known. A large number of scatter holes in the lid of the closure, which are arranged on a circle, are closed by an equal number of coinciding knobs of the same arrangement. These knobs are arranged on projections of the inner wall surface of the container-side part of the closure. To open the closure, the lid is rotated about its axis of rotation; as a result, the scatter holes move away from the knobs mentioned and the spreading material can be shaken out of the holes.
Die Aufgabe, die mit der vorliegenden Erfindung gelöst werden soll, ist die Schaffung eines Verschlusses für Tuben oder weiche Kunststoff-Flaschen, der nicht völlig abgeschraubt werden muss, um das Ausdrücken des Inhaltes zu ermöglichen, und der in einfacher Weise mit einer Originalitäts-Sicherung verbunden werden kann.The object that is to be achieved with the present invention is to provide a closure for tubes or soft plastic bottles, which does not have to be completely unscrewed to enable the contents to be expressed, and which can be easily secured with a tamper-evident device can be connected.

Das erste Ausführungsbeispiel ist in Fig. 1a,b im Schnitt, in Fig. 1b in einer Draufsicht dargestellt. Ein Tubenkörper 1 trägt - mit ihm beispielsweise durch Schweissen verbunden - eine Schulter 2, die sich nach oben verengt zu einem Tubenhals 7. Dieser weist einen Ringwulst 4 auf. Eine Verschlusskappe 3 ist gegliedert in zwei konzentrische zylindrische Teile 8, 9 und eine Abschlussplatte 10, wobei der innere zylindrische Teil 9 mit kleinem Spiel auf den Tubenhals 7 passt und eine dem Ringwulst 4 entsprechende Ringnut 5 aufweist. Ringwulst 4 und Ringnut 5 sind so geformt, dass die Verschlusskappe 3 wohl - durch Dehnen des inneren zylindrischen Teiles 9 - über den Tubenhals 7 geschoben werden kann, dass aber ein Abziehen der Verschlusskappe 3 ohne deren Zerstörung nicht mehr möglich ist. Der Tubenhals 7 ist bis auf eine exzentrisch liegende Oeffnung 6 verschlossen. In der dargestellten Position der Verschlusskappe 3 ist die Oeffnung 6 von der Abschlussplatte 10 dicht verschlossen. Selbstverständlich braucht die äussere Gliederung der Verschlusskappe 3 nicht die dargestellte Form zu haben, sondern kann bezüglich der Abschlussplatte 10 eben, konvex oder konkav gestaltet sein; ferner kann der Uebergang von Abschlussplatte 10 zu äusserem zylindrischen Teil 8 ein allmählicher sein; auch braucht der äussere zylindrische Teil 8 nicht wirklich eine zylindrische Form aufzuweisen: polygonale Gestaltungen sind ebenso denkbar und bilden eine Geschmacks-Frage, nicht eine technische.The first embodiment is shown in Fig. 1a, b in section, in Fig. 1b in a plan view. A
Im Tubenhals 7 ist, ebenfalls exzentrisch, um einen Winkel α gegenüber der Oeffnung 6 versetzt, aber im gleichen Abstand von der Achse des Tubenhalses 7, ein nach unten geschlossener, nach oben offener Zylinder 11 angeformt, der eine, von einer Schraubenfeder 12 nach oben gedrückte Kugel 13 enthält. Die Kugel 13 ist im Zylinder 11 mit Spiel beweglich und verschliesst - in der Position gemäss Fig. 1a, b - eine Oeffnung 14 in der Verschlusskappe 3, welche Oeffnung 14 kugelschalen-segmentartig geformt ist.In the
Soll der Tube etwas von ihrem Inhalt entnommen werden, so wird die Verschlusskappe 3 um den Winkel α gedreht. Dabei drückt die Abschlussplatte 10 die Kugel 13 gegen den Widerstand der Schraubenfeder 12 nach unten; die Oeffnung 14 in der Verschlusskappe 3 kommt über die Oeffnung 6 zu liegen.: Der Inhalt der Tube kann entnommen werden. Nach dem Zurückdrehen in die Ausgangsposition gemäss Fig. 1a, b verschliesst die Kugel 13 die Oeffnung 14 wieder, und allfällige Reste des Tubeninhaltes können mit dem Finger sauber von der Kugel entfernt werden.If some of the content of the tube is to be removed, the
Die Beschränkung der Drehbarkeit der Verschlusskappe 3 auf den vorgesehen Winkel α wird durch das Zusammenwirken eines Nockens 15, der an der Schulter 2 angeformt ist, und einer seitlichen Ausnehmung 16 im äusseren zylindrischen Teil 8 der Verschlusskappe 3 bewirkt. Die Ausnehmung 16 ist demnach so breit, dass sie unter Berücksichtigung der Breite des Nockens 15 die Drehung der Verschraubkappe 3 um den Winkel α zulässt. Die mit 17 bis 20 bezeichneten Teile werden im Zusammenhang mit Fig. 4 erläutert.The restriction of the rotatability of the
Fig. 4 zeigt eine perspektivische Phantom-Darstellung des Ausführungsbeispiels gemäss Fig. 1a, b. In den Hohlraum zwischen der Schulter 2 und den zylindrischen Teilen 8, 9 ist ein Ring 17 eingelegt, der über einen Streifen 19 und eine Sollbruchstelle 18 mit einem ausserhalb der Verschlusskappe 3 befindlichen Lappen verbunden ist. Die Sollbruchstelle 18 liegt unmittelbar innerhalb der Ausnehmung 16. Die Dimensionen des Lappens 20 sind grösser als die Breite der Ausnehmung 16. Die Dicke des Materials dieser Originalitätssicherung, bestehend aus den mit 17 bis 20 bezeichneten Teilen, entspricht vorzugsweise der Höhe der Ausnehmung 16. Der Lappen 20 kann beispielsweise mit Preis, Produktinformation und Haltbarkeitsdatum versehen werden. Ohne Zerreissen der Sollbruchstelle 18 kann die Verschlusskappe 3 nicht gedreht, und die Verschlusskappe 3 sonst nur unter Gewaltanwendung und deren Zerstörung von der Tube abgesprengt werden.FIG. 4 shows a perspective phantom representation of the exemplary embodiment according to FIGS. 1a, b. In the cavity between the
Die beschriebene Gestaltung bewirkt, dass der Streifen 19 nach Abreissen des Lappens 20 - also- nach Verletzung der Originalitätssicherung - die Drehung der Verschlusskappe 3 nicht behindert. Ferner ist es nicht möglich, den Lappen 20 in die Ausnehmung 16 zurückzustecken, um Originalität vorzutäuschen.The design described has the effect that the
In einer nicht gezeichneten Variante zu Fig. 4 ist der Ring 17 so gross, dass die Sollbruchstelle 18 zwischen den Aussenrand des Ringes 17 und den Lappen 20 zu liegen kommt, wobei der Streifen 19 wegfällt. Die in Fig. 2 dargestellte Originalitätssicherung ist vorzugsweise aus Karton. Dies erlaubt kostengünstige Herstellung, problemloses Bedrucken und leichte Integration während des Verschliessvorganges.In a variant not shown in FIG. 4, the
Fig. 2 zeigt ein zweites Ausführungsbeispiel. Anstelle der Kugel 13 aus Fig. 1 tritt hier ein Kugelteil 21, der über ein ringförmiges Federgelenk 22 mit dem dem stirnseitigen Abschluss des Tubenhalses 7 verbunden ist und im gleichen Spritzwerkzeug hergestellt wird. Die übrigen Teile und Ausbildungen entsprechen jenen von Fig. 1. Beim Drehen der Verschlusskappe 3 wird der Kugelteil 21 gegen die Nachgiebigkeit des Federgelenkes 22 nach unten gedrückt.Fig. 2 shows a second embodiment. Instead of the
Die die Originalitätssicherung darstellenden Teile 17 bis 20 sind sowohl in Fig. 2 als auch in Fig. 3 unverändert und werden nicht mehr beschrieben.The
Ein weiteres Ausführungsbeispiel ist in Fig. 3 a, b dargestellt. Hier weist der stirnseitige Abschluss des Tubenhalses 7, bei unverminderter Wandstärke, einen Aufsatz in Form eines Kugelsegmentes 23 auf. Die Abschlussplatte 10 ist in einem zentralen Bereich 24 dünner ausgeführt als der Rest der Abschlussplatte 10. Wird die Verschlusskappe 3 gedreht, so gibt die Abschlussplatte 10 im Bereich 24 nach oben nach, bis das Kugelsegment 23 in eine kugelsegmentförmige Ausbuchtung 25 im Bereich 24 der Abschlussplatte 10 einrastet. Diese Ausbuchtung 25 ist im Bezug auf die Oeffnung 14 in der Verschlusskappe 3 ebenfalls um einen Winkel α versetzt, so dass das Einrasten des Kugelsegmentes 23 in der Ausbuchtung 25 in der gleichen Position der Verschlusskappe 3 erfolgt, wie das Freigeben der Oeffnung 6 im Tubenhals 7 durch die Oeffnung 14 in der Verschlusskappe 3.Another embodiment is shown in Fig. 3 a, b. Here, the front end of the
Die Vorteile der beschriebenen Gestaltungen liegen vornehmlich darin, dass die Tube, die mit dem erfindungsgemässen Verschluss versehen ist, im wesentlichen verschlossen bleibt. Der kleine Rest des Tubeninhaltes, der in der Oeffnung 14 in der Verschlusskappe 3 verbleibt, wenn das ausgedrückte Quantum beispielsweise mit einem Finger entfernt wurde, wird durch die Kugel 13, das Kugelsegment 23 oder den Kugelteil 21 nach dem Zurückdrehen der Verschlusskappe 3 aus der genannte Oeffnung 14 herausgedrückt, und kann abgewischt werden. Es entstehen weder an der Tubenöffnung noch am Tubendeckel unhygienische und unappetitliche Ansammlungen von vertrocknetem oder verdorbenem Tubeninhalt; zudem kann der Inhalt der Tube weder verunreinigt werden noch antrocknen. Da kein Deckel abgenommen wird, kann dieser auch nicht weggelegt oder verlegt werden und auch nicht zu Boden fallen. Weder der Tubeninhalt noch das Innere des Deckels kommen je mit Fremdstoffen in Kontakt. Dies ist von besonderer Bedeutung, da je länger je mehr auf konservierende und bakteriostatische Zusätze zu Tubeninhalten verzichtet wird.The advantages of the described designs are primarily that the tube which is provided with the closure according to the invention remains essentially closed. The small remainder of the tube content, which remains in the
Durch Anpassen der Grössen der Oeffnung 14 und der sie verschliessenden Kugel 13 oder der Kugelteile 21, 23, ist der erfindungsgemässe Tubenverschluss für jeden Verwendungszweck, bzw. Inhalt geeignet.By adapting the sizes of the
