Abstract

A container with a snap-fit lid and tamperproofing for recognisable and irreversible indication of initial opening has at least one tab, but preferably two or more tabs which are connected non-releasably to the lid with foldable portions, at least one of which rests flatly against the wall of the container in the snapped-on position of the lid and is firmly connected to said wall.

Description

Die Erfindung betrifft einen Behälter mit aufstülpbarem Deckel und Originalitätssicherung zur erkennbaren und nicht reversiblen Anzeige des erstmaligen Öffnens, z. B. und insbesondere für die Verpackung von vor allem verderblichen Lebensmitteln.The invention relates to a container with an attachable lid and tamper-evident for recognizable and non-reversible display of the first opening, for. B. and especially for the packaging of especially perishable food.

Originalitätssicherungen sind in vielfältiger Form bekannt. So ist es z. B. üblich bei Behältern mit aufstülpbarem Deckel vor dem Aufstülpen des Deckels die Behälteröffnung zusätzlich mit einer Folie aus Kunststoff, Aluminium oder dgl. fest zu verkleben. Um an den Inhalt des Behälters zu gelangen, muß nach dem Öffnen des Deckels die Folie abgerissen oder durchstoßen werden, so daß für jedermann erkennbar ist, wenn der Behälter bereits geöffnet wurde. Diese Art der Originalitätssicherung ist zwar sicher, aber relativ kostenaufwendig.Tamper evidence is known in many forms. So it is z. B. usual for containers with a cover that can be put on, before the cover is put on, the container opening additionally with a film made of plastic, aluminum or the like. In order to get to the contents of the container, the film must be torn off or pierced after opening the lid, so that everyone can see when the container has already been opened. While this type of tamper-evident is secure, it is relatively expensive.

Es sind weiterhin Originalitätssicherungen bekannt, die darauf beruhen, daß die Behälterwand und der Behälterdeckel mit einem besonders geformten Etikett beklebt werden, daß aus zwei größeren Teilen mit einem dazwischenliegenden Steg besteht. Nach Aufdrücken des Deckels auf den Behälter wird der eine Teil des Etikettes an der Behälterwand angeklebt, der Verbindungssteg straff über die Deckelkante gezogen und der andere Teil des Etiketts auf dem Deckel aufgeklebt. Diese Art der Originalitätssicherung ist zwar wesentlich kostengünstiger als die erstgenannte, bietet aber weniger Sicherheit vor Mißbrauch und hat den Nachteil, daß sie, z. B. beim Transport, unbeabsichtigt leicht beschädigt werden kann und damit eine erstmalige Öffnung des Behälters anzeigt, die im Grunde gar nicht erfolgt ist.There are also known tamper-evident devices which are based on the container wall and the container lid being stuck with a specially shaped label, which consists of two larger parts with an intermediate web. After pressing the lid onto the container, one part of the label is glued to the container wall, the connecting web is pulled tightly over the edge of the lid and the other part of the label is glued to the lid. This type of tamper-evident protection is considerably less expensive than the former, but offers less security against misuse and has the disadvantage that it, e.g. B. during transport, can easily be accidentally damaged and thus indicates a first-time opening of the container, which has basically not occurred.

Der im Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Originalitätssicherung für Behälter mit aufstülpbarem Deckel zu schaffen, die einfach aufgebaut, leicht handhabbar, kostengünstig herstellbar ist und bei unbeabsichtiger Belastung nicht beschädigt oder zerstört wird.The invention specified in claim 1 is based on the problem of creating a tamper-evident device for containers with an attachable lid, which is simple in construction, easy to handle, inexpensive to manufacture and is not damaged or destroyed in the event of unintentional loading.

Die Lösung dieses Problems ist durch die im kennzeichnenden Teil des Hauptanspruchs erfaßten Merkmale charakterisiert. Weitere erfinderische Merkmale gehen aus den Unteransprüchen hervor.The solution to this problem is characterized by the features covered in the characterizing part of the main claim. Further inventive features emerge from the subclaims.

Gegenüber dem zum Stand der Technik gehörenden Originalitätssicherungen ergibt sich durch die Erfindung eine kostengünstigere Herstellung und Verarbeitung und eine Erhöhung der Sicherheit gegenüber unbeabsichtigter Beschädigung oder Zerstörung.Compared to the tamper-evident devices belonging to the state of the art, the invention results in less expensive production and processing and an increase in security against inadvertent damage or destruction.

Die Erfindung soll nachstehend an Hand eines bevorzugten Ausführungsbeispiels in Verbindung mit den Fig. 1 bis 3 näher erläutert werden.The invention will be explained below with reference to a preferred embodiment in connection with FIGS. 1 to 3.

Es zeigen:

  • Fig. 1 einen Teil der Behälterwand und einen Teil des aufstülpbaren Deckels mit anhängender Lasche zur Originalitätssicherung vor dem Aufstülpen des Deckels und der Befestigung der Lasche an der Behälterwand.
  • Fig. 2 die in Fig. 1 dargestellten Einzelheiten nach dem Aufstülpen des Deckels und der Befestigung der Lasche zur Originalitätssicherung an der Behälterwand.
  • Fig. 3 den oberen Teil des Behälters mit aufgestülptem Deckel und drei an der Behälterwand befestigten Laschen zur Originalitätssicherung.
Show it:
  • Fig. 1 shows a part of the container wall and a part of the cover which can be put on with an attached tab for tamper-evident protection before the cover is put on and the tab is fastened to the container wall.
  • Fig. 2 shows the details shown in Fig. 1 after putting on the lid and attaching the tab to ensure tamper evidence on the container wall.
  • Fig. 3 shows the upper part of the container with the lid and three tabs attached to the container wall for tamper-evident.

Der in Fig. 1 dargestellte Zustand des Behälters 1 vor dem Überstülpen des Deckels 2 zeigt eine in dieser Phase noch seitlich abstehende Lasche 3 mit Materialschwächungen 4, die die Lasche 3 in zwei Abschnitte untergliedern und ein leichtes Falten der Lasche an diesen Stellen gestatten. Anstelle von Materialschwächungen 4 können auch andere Gelenkausbildungen, etwa biegbare Abschnitte, vorgesehen sein, die ein Klappen bzw. Biegen der Abschnitte an die Behälterwand nach Aufsetzen des Deckels ermöglichen. Fig. 1 zeigt im übrigen den Deckel in der Entformungsstellung.The state of the container 1 shown in FIG. 1 before the cover 2 is put on shows a tab 3 with material weakenings 4 that still protrudes laterally in this phase, dividing the tab 3 into two sections and allowing the tab to be folded slightly at these points. Instead of weakening the material 4, other articulations, such as bendable sections, can also be provided, which allow the sections to be folded or bent onto the container wall after the cover has been put on. Fig. 1 shows the rest of the lid in the demolding position.

Der Zustand nach Überstülpen des Deckels 2 über den Rand des Behälters 1 ist in Fig. 2 dargestellt. Zur Originalitätssicherung wurde die am Dekkel 2 angeordnete und einstückig mit dem Deckel zweckmäßigerweise durch Spritzgießen geformte Lasche 3 zur Wandung des Behälters 1 gefaltet oder geklappt, so daß der vordere Abschnitt der Lasche 3 plan an der Wandung des Behälters 1 anliegt und mit dieser z. B. durch eine feste bzw. unlösbare Verklebung oder Verschweißung verbunden werden kann. Der Deckel weist wenigstens so viele über den Umfang verteilt angeordnete Laschen auf, wie es für eine wirksame Originalitätssicherung erforderlich ist. Im dargestellten Ausführungsbeispiel sind mindestens zwei am Rand des Deckels, sich zweckmäßigerweise gegenüberliegend befindliche Laschen 3 vorgesehen.The state after the cover 2 has been placed over the edge of the container 1 is shown in FIG. 2. To ensure tamper-evident, the flap 3 arranged on the lid 2 and integrally formed with the lid by injection molding was folded or folded to the wall of the container 1, so that the front section of the flap 3 lies flat against the wall of the container 1 and with this z. B. can be connected by a fixed or permanent connection or welding. The lid has at least as many tabs distributed over the circumference as is necessary for an effective tamper-evident device. In the exemplary embodiment shown, at least two tabs 3, which are expediently located opposite one another, are provided on the edge of the cover.

Günstig ist die einstückige Herstellung des Deckels mit den anhängenden Laschen im Spritzgießverfahren, wobei gleichzeitig die Materialschwächungen 4, die als Gelenk dienen, mit ausgebildet werden. Sehr günstig ist ferner die Ausführung der Materialschwächungen als Filmscharnier, wie dies in den Zeichnungen dargestellt ist. Aber auch jede andere Materialschwächung, z. B. durch Perforation ist denkbar. Im dargestellten Ausführungsbeispiel sind die Materialschwächungen durch V- oder U-förmige Kerben oder Nuten gebildet, die mit ihrem Boden die Filmscharniere bilden. Vorteilhaft sind je Lasche zwei Filmscharniere vorgesehen. In Fig. 1 ist die äußerste Kerbe mit der Öffnung nach oben dargestellt. Sie kann zweckmäßigerweise auch mit der Öffnung nach unten ausgebildet sein.The one-piece production of the cover with the attached tabs using the injection molding process is favorable, with the material weakenings 4, which serve as a joint, being formed at the same time. The design of the material weakenings as a film hinge is also very favorable, as shown in the drawings. But also any other material weakening, e.g. B. by perforation is conceivable. In the exemplary embodiment shown, the material weakenings are formed by V-shaped or U-shaped notches or grooves, which form the film hinges with their base. Two film hinges are advantageously provided for each tab. In Fig. 1 the outermost notch is shown with the opening upwards. You can also expediently with the opening down be educated.

Wie schon erwähnt, erfolgt die unlösbare Befestigung des plan an der Wandung des Behälters 1 anliegenden Abschnittes der Lasche 3 zweckmäßigerweise durch eine unlösbare Verklebung. Wenn der Behälter, der Deckel und die anhängende Lasche aus Kunststoff bestehen bzw. mit Kunststoff beschichtet sind, ist vor allem eine Verbindung durch Heißsiegelung zweckmäßig. Besonders günstig ist eine Siegelung durch Ultraschallerhitzung, wozu der mit der Wandung des Behälters zu verbindende Abschnitt der Lasche zweckmäßigerweise mit einer Riffelung versehen wird. Diese Riffelung läßt sich bei der einstückigen Herstellung des Dekkels im Spritzgießverfahren mit angießen.As already mentioned, the non-detachable fastening of the section of the tab 3 lying flat against the wall of the container 1 is expediently carried out by non-detachable gluing. If the container, the lid and the attached tab are made of plastic or are coated with plastic, a connection by heat sealing is particularly expedient. Sealing by ultrasonic heating is particularly favorable, for which purpose the section of the tab to be connected to the wall of the container is expediently provided with corrugation. This corrugation can be cast on with the one-piece production of the cover in an injection molding process.

Der in Fig. 3 dargestellte Behälter 1 mit aufgestülptem Deckel 2 zeigt drei an der Wandung des Behälters 1 befestigte Laschen 3 zur Originalitätssicherung. Bei kleinen Behältern und bei ausreichender Festigkeit und Steifheit des Deckels sind jedoch auch zwei gegenüberliegend angeordnete Laschen zur Originalitätssicherung ausreichend. Die Zahl der Laschen muß so gewählt werden, daß es nicht möglich ist, ohne Beschädigung der Originalitätssicherung den Deckel anzuheben und an den Inhalt des Behälters 1 zu gelangen.The container 1 shown in FIG. 3 with the cover 2 placed on it shows three tabs 3 fastened to the wall of the container 1 to ensure tamper evidence. In the case of small containers and with sufficient strength and rigidity of the lid, however, two tabs arranged opposite one another are sufficient to ensure tamper evidence. The number of tabs must be chosen so that it is not possible to lift the lid and get to the contents of the container 1 without damaging the tamper-evident device.

Im dargestellten Ausführungsbeispiel sind die Laschen am Deckel ausgebildet. Es liegt jedoch gleichfalls im Rahmen der Erfindung, die Laschen ggf. am Behälter vorzusehen.In the illustrated embodiment, the tabs are formed on the lid. However, it is also within the scope of the invention to provide the tabs on the container if necessary.

Zweckmäßigerweise ist die Behältergröße auf einen Rauminhalt von 0,5 bis ca. 10 I festgelegt.The container size is expediently set to a volume of 0.5 to approximately 10 l.

Schließlich weist der Deckel einen oder mehrere nach innen vorspringende Rastvorsprünge oder einen umlaufenden Rastwulst 6 zum Aufschnappen des Deckels 2 auf den Behälter 1 auf, an dem sich ein schulterförmig schräg nach außen verlaufender Abschnitt 7 anschließt, der in einen vertikalen Endabschnitt 8 ausläuft, an dem die Laschen 3 angeformt sind.
