Description

Die vorliegende Erfindung bezieht sich auf einen Behälter mit einem am Rumpf nicht-abnehmbar befestigten Kunststoffverschluss, wobei der Deckel ein Verschlussteil mit einer Schwächungsritze, die mit einem Gelenk verbunden ist und eine einstückig mit dem Verschlussteil hergestellte Lasche aufweist.The present invention relates to a container with a plastic closure which is non-removably attached to the fuselage, the lid having a closure part with a weakening groove which is connected to a joint and has a tab which is produced in one piece with the closure part.

Ein solcher Behälter ist aus der US-A-4 253 582 bekannt, der dort als sog. « easy open »-Behälter ausgebildet ist. Naturgemäss wird dort grössten Wert auf ein leichtes Oeffnen gelegt und an ein Wiederverschliessen des Deckels ist nicht gedacht. Ausserdem werden der Deckel und der Rumpf getrennt hergestellt und die Oberkante des Rumpfes um den Deckel gebördelt.Such a container is known from US-A-4 253 582, which is designed there as a so-called “easy open” container. Naturally, great importance is attached to easy opening and there is no thought of reclosing the lid. In addition, the lid and the fuselage are manufactured separately and the upper edge of the fuselage is crimped around the lid.

Aus der NL-A-7 116 976 ist ein Behälter bekannt, bei welchem der Deckel mit dem Aufreissverschluss einstückig mit dem Rumpf hergestellt ist. Das Oberteil dieses Behälters ist stark verjüngt und weist eine relativ kleine Oeffnung auf, so dass das Einfüllen relativ aufwendig ist, da zu diesem Zwecke der Behälter auf den Kopf, resp. auf den Verschlussteil gestellt werden muss. Der Verschluss besteht aus einem spiraligen Teil mit einer Lasche und kann nicht wiederverschlossen werden.From NL-A-7 116 976 a container is known in which the lid with the zipper is made in one piece with the body. The upper part of this container is very tapered and has a relatively small opening, so that the filling is relatively complex, because for this purpose the container upside down, respectively. must be placed on the closure part. The closure consists of a spiral part with a flap and cannot be closed again.

Es ist demgegenüber Aufgabe der vorliegenden Erfindung einen Behälter zu schaffen, der einerseits wirtschaftlich und mit geringerem Aufwand hergestellt werden kann und der andererseits stapelbar ist und leicht gefüllt werden kann und der sich mit geringem Aufwand öffnen und gut wiederverschliessen lässt.In contrast, it is an object of the present invention to provide a container which, on the one hand, can be produced economically and with less effort and, on the other hand, is stackable and can be filled easily and which can be opened and resealed with little effort.

Diese Aufgabe wird mit einem in den Ansprüchen beschriebenen Behälter gelöst.This object is achieved with a container described in the claims.

Im Folgenden wird die Erfindung anhand einer Zeichnung von Ausführungsbeispielen näher erläutert werden.

  • Figur 1 zeigt, teilweise im Schnitt, zwei aufeinandergestapelte erfindungsgemässe Behälter,
  • Figur 2 zeigt den Behälter von Figur 1 von oben,
  • Figur 3 zeigt das Oeffnen eines Behälters gemäss Figur 1,
  • Figur 4 zeigt, teilweise im Schnitt, eine Ausführungsvariante von zwei aufeinandergestapelten, leeren Behältern,
  • Figur 5 zeigt ein weiteres Ausführungsbeispiel im Schnitt und
  • Figur 6 zeigt das Beispiel von Figur 5 in Draufsicht.
The invention will be explained in more detail below with reference to a drawing of exemplary embodiments.
  • FIG. 1 shows, partly in section, two containers according to the invention stacked on top of one another,
  • Figure 2 shows the container of Figure 1 from above,
  • FIG. 3 shows the opening of a container according to FIG. 1,
  • FIG. 4 shows, partly in section, an embodiment variant of two empty containers stacked on top of one another,
  • Figure 5 shows a further embodiment in section and
  • Figure 6 shows the example of Figure 5 in plan view.

Man erkennt in Figur 1 einen Behälter 1. bestehend aus einem zylindrischen Rumpf 2, einem einstückig damit hergestellten Deckel 3 und einem nach dem Einfüllen des Behälters befestigten Boden 4. In vorliegendem Beispiel ist der Boden versiegelt und umgebördelt. Der Deckel 3 weist einen umlaufenden Kragen 5 auf, der einen Einschnitt 6 besitzt. Am Deckel befindet sich ein Oeffnungsteil 7, der eine halbkreisförmige Schwächungsritze 8 und ein aus einer Nut bestehendes Gelenk 9, aufweist, das die beiden Endpunkte der Schwächungsritze miteinander verbindet. Innerhalb des durch die Schwächungsritze und dem Gelenk gebildeten Teil ist eine Lasche 10 angeordnet, wobei der gesamte Deckel mit dem Oeffnungsteil mitsamt dem Rumpf, einstückig aus Kunststoff gefertigt ist. Zur Befestigung der Lasche sind an beiden Seiten des Einschnittes Haltenocken 11 angebracht, unter welchen die Lasche eingeschnappt werden kann. Um die Lasche besser anpacken zu können, weist sie Rippen 12 auf. Wie ferner aus Figur 1 hervorgeht, sind die gefüllten Behälter stapelbar, wobei der Rand 13 des Bodens um den umlaufenden Kragen 5 passt.A container 1 can be seen in FIG. 1, consisting of a cylindrical body 2, a cover 3 produced in one piece therewith and a base 4 fastened after the container has been filled in. In the present example, the base is sealed and flanged. The cover 3 has a circumferential collar 5 which has an incision 6. On the cover there is an opening part 7, which has a semicircular weakening crack 8 and a joint 9 consisting of a groove, which connects the two end points of the weakening crack to one another. A tab 10 is arranged within the part formed by the weakening crack and the joint, the entire cover with the opening part together with the body being made in one piece from plastic. To attach the tab, holding cams 11 are attached on both sides of the incision, under which the tab can be snapped. In order to better tackle the tab, it has ribs 12. As can also be seen from FIG. 1, the filled containers can be stacked, the edge 13 of the base fitting around the circumferential collar 5.

Aus Figur 3 ist das Oeffnen des Behälters ersichtlich.The opening of the container can be seen from FIG.

Die Lasche wird aus der Halterung gelöst und aufgerichtet, wonach ein Zug darauf ausgeübt werden kann, um das Oeffnungsteil an den Schwächungsritzen aufzureissen. Es kann auch vorteilhaft sein, zum Oeffnen Scherbewegungen mit der Lasche auszuführen. Es ist selbstverständlich, dass das Gelenk 7 derart gestaltet ist, dass es beim Aufreissen nicht auch abgerissen wird. Je nach Verwendungszweck und Inhalt des Behälters kann der Einschnitt 6 als Ausguss dienen. Nach dem Gebrauch kann das Oeffnungsteil wieder verschlossen werden, indem die Lasche 10 unter die Nocken 11 eingerastet wird.The tab is released from the holder and raised, after which a pull can be exerted on it to tear open the opening part at the weakening gaps. It can also be advantageous to perform shear movements with the tab for opening. It goes without saying that the joint 7 is designed in such a way that it is not also torn off when it is torn open. Depending on the intended use and the content of the container, the incision 6 can serve as a spout. After use, the opening part can be closed again by latching the tab 10 under the cams 11.

Das Verschlussteil 7 kann beliebig gestaltet sein und kann auch den gesamten Verschluss oder Deckel umfassen, wobei die Schwächungsritze um den ganzen Verschluss läuft. Falls der ganze Verschluss entfernt wird, und die Dose wieder verwendbar sein soll, ist es zweckmässig, diese mit einer Verschlusskappe zu versehen.The closure part 7 can be of any design and can also comprise the entire closure or cover, the weakening crack running around the entire closure. If the entire closure is removed and the can is to be reusable, it is advisable to provide it with a closure cap.

Gemeinsam all diesen Ausführungsformen ist, dass die Lasche 10 einstückig mit dem Verschluss aus Kunststoff hergestellt ist, und dieser Verschluss mindestens eine Schwächungsritze aufweist.Common to all of these embodiments is that the tab 10 is made in one piece with the closure from plastic, and this closure has at least one weakening crack.

In einer weiteren Ausführungsvariante gemäss Figur 4 ist der Rumpf 14 kegelstumpfförmig gestaltet und verjüngt sich nach oben. Wie im ersten Ausführungsbeispiel, gemäss den Figuren 1 bis 3, ist der Rumpf und der Deckel 3, bzw. Verschluss, einstückig aus Kunststoff gespritzt und besitzt, beispielsweise, die gleichen Elemente wie der Behälter des ersten Ausführungsbeispiels. Zusätzlich zum ersten Ausführungsbeispiel können diese Behälter im leeren Zustand gestapelt werden, wobei die Lasche 10 so angeordnet ist, wie sie aus der Fabrikation kommt, d. h. senkrecht nach oben, so dass ein Behälter nach dem anderen von der Stapel an der Lasche leicht abgenommen werden kann. Dabei ist, wie in Figur 4 dargestellt, die Konizität des Rumpfes derart gewählt, dass die Lasche im senkrechten Zustand nicht eingedrückt wird. Im gefüllten Zustand stützt sich der Behälterboden wieder auf den Kragen 5 des Deckelteils.In a further embodiment variant according to FIG. 4, the fuselage 14 is frustoconical and tapers upwards. As in the first exemplary embodiment, according to FIGS. 1 to 3, the fuselage and the lid 3, or closure, are injection-molded in one piece from plastic and have, for example, the same elements as the container of the first exemplary embodiment. In addition to the first embodiment, these containers can be stacked empty, with the tab 10 arranged as it comes from manufacture, i. H. vertically upwards so that one container after the other can be easily removed from the stack by the tab. As shown in FIG. 4, the taper of the fuselage is selected such that the tab is not pressed in in the vertical state. In the filled state, the container base is supported again on the collar 5 of the cover part.

In den Figuren 5 und 6 ist ein bevorzugtes Ausführungsbeispiel dargestellt. Der Rumpf 2 ist wie beim ersten Beispiel nach Figur 1 zylindrisch und weist den gleichen Boden 14 mit Rand 13 auf, der um den Kragen 24 des Deckels 15 passt. Der nach oben sich verjüngende Kragen weist einen Einschnitt 19 auf, der ein wenig schmaler ist als die Breite der Lasche 20, um eine Klemmwirkung zu erzielen. Die Lasche 20 ist mit einem Loch 21 versehen, das zu einem Zapfen 22 passt, der am Deckel angeordnet ist. Dadurch kann bei der Herstellung die Lasche befestigt werden, so dass sie den Behälter nicht überragt und beim Einfüllvorgang nicht stört. Es ist auch möglich, eine andere Befestigungsart vorzusehen, um die Lasche am Deckel zu halten, beispielsweise durch ein Verschweissen an einem Punkte.In Figures 5 and 6 is a preferred one Embodiment shown. The fuselage 2 is cylindrical as in the first example according to FIG. 1 and has the same base 14 with an edge 13 which fits around the collar 24 of the cover 15. The upwardly tapering collar has an incision 19 which is a little narrower than the width of the tab 20 in order to achieve a clamping effect. The tab 20 is provided with a hole 21 which fits a pin 22 which is arranged on the cover. This allows the tab to be attached during manufacture so that it does not protrude from the container and does not interfere with the filling process. It is also possible to provide a different type of fastening in order to hold the tab on the cover, for example by welding at one point.

Wie aus den Figuren 5 und 6 ferner hervorgeht, ist die Lasche nahe der Schwächungsritze 17 des Verschlussteils 16, beim Einschnitt 19, angeordnet, um eine grösstmögliche Kraftübertragung beim Oeffnen zu gewährleisten. Diese Schwächungsritze erstreckt sich über einen wesentlichen Teil des Umfangs, das heisst mindestens über dreiviertel desselben und ist über ein Gelenk 18 verbunden, das nahe dem entgegengesetzten Ende angeordnet ist. Am Orte der Lasche, wo die grösste Kraft beim Oeffnen aufgewendet wird, befindet sich an der Unterseite des Deckels eine T-förmige Verstärkungsrippe 23.As can also be seen from FIGS. 5 and 6, the tab is arranged near the weakening crack 17 of the closure part 16, at the incision 19, in order to ensure the greatest possible transmission of force when opening. This weakening crack extends over a substantial part of the circumference, that is to say over at least three quarters thereof, and is connected via a joint 18 which is arranged near the opposite end. At the location of the tab, where the greatest force is applied when opening, there is a T-shaped reinforcing rib 23 on the underside of the cover.

Behälter mit den erfinderischen Merkmalen brauchen nicht nur zylindrisch oder konisch zu sein. Es können auch ovale oder rechteckige Behälter sein und solche, deren Wände sich nach oben leicht verjüngen.Containers with the inventive features need not only be cylindrical or conical. They can also be oval or rectangular containers and those whose walls taper slightly upwards.

Allen solchen erfindungsgemässen Behältern ist gemeinsam, dass sie sich, mit Ausnahme des Bodens, auf wirtschaftlicher Weise einstückig spritzen lassen und dass sie leicht, auf bestehenden Anlagen, abgefüllt und geschlossen werden können. Bei geeigneter Dimensionierung des Deckels lässt sich der Oeffnungsteil leicht öffnen und bequem schliessen.All such containers according to the invention have in common that, with the exception of the base, they can be sprayed in one piece economically and that they can be easily filled and closed on existing systems. With a suitable dimensioning of the lid, the opening part can be opened and closed easily.
