Description

Die vocliegende Neuerung betrifft einen Kunststeffbeutel mit einer Einfüliöffnung, vorzugsweise zum Vecpacken von Tiefküklkost, wie Fleisch, Gemüse, Fisch ed,dgl.The voc lying innovation relates to a plastic bag with a filling opening, preferably for packing frozen foods such as meat, vegetables, fish ed, etc.

Tiefkühlkest wird üblicherweise zwecks Lagerung in kunst-Stoffbeultel. verpackt.Frozen food is usually used for storage in plastic bumps. packed up.

Dabei ist es möglich, Tiefkühlkost in flüssiger oder fester Zustandsart zu verpacken. Beim Verpacken von flüssiger Tiefkühlkost ist es erforderlich, die Einfüllöffnung des Beutels mittels eines Schweißgerätes zu verschließen. Dazu ist im Haushalt ein Schweißgerät erforderlich. Handelts es sich um feste Tiefkühlkost, wie beispielsweise Fleisch, Gemüse, Fisch od.dgl., ist ein Verschweißen der Einfülloffnunc nicht erforderlich. Die Beutel werden dann mittels Beutelverschlüsse, wie Klammern, Clipse, Gummiringe od. dgl. verschlossen.It is possible to pack frozen food in a liquid or solid state. When packaging liquid frozen food, it is necessary to seal the bag opening using a welding machine. This requires a welding machine in the household. If it is solid frozen food, such as meat, vegetables, fish or the like, it is not necessary to weld the filling openings. The bags are then closed by means of bag closures, such as clips, clips, rubber rings or the like.

Die beim Verpacken von fester Tiefkühlkost benötigten Beutelverschlüsse müssen in ausreichender

Figure imgb0001
vorrätig sein, was naturgemäß oft nicht der Fall ist.The bag closures required when packing solid frozen foods must be sufficient
Figure imgb0001
be in stock, which naturally is often not the case.

Aufgabe der vorliegenden Neuerung ist es, einen Kunststoffbeutel der gattungsgemäßen Art zu schaffen, der sich ohne zusätzlichen Beutelverschluß auf einfache Art verschließen läßt.The object of the present innovation is to create a plastic bag of the generic type which can be easily closed without an additional bag closure.

Die neuerungsgemäße Lösung sieht vor, daß im Bereich der Einfüllöffnung mindestens an einer Beutelwandung ein aus einem faltbaren, aber formstabilen Material hergestellter Verschlußstreifen vorgesehen ist.The solution according to the invention provides that a closure strip made of a foldable but dimensionally stable material is provided in the area of the filling opening at least on one wall of the bag.

Nunmehr ist es möglich, den Beutel ohne einen zusätzlich benötigten Beutelverschluß durch ein- oder mehrmaliges Umfalten des oberen, offenen Beutelrandes zu verschließen, so daß die eingefüllte Tiefkühlkost gegen ein unbeabsichtigtes Herausgleiten gesichert ist. Durch die Verwendung eines faltbaren, aber formstabilen Materials kann der Beutel auf einfachste Weise verschlossen werden, da das Material des Verschlußstreifens dem Umfalten des oberen, offenen Beutelrandes keine oder nicht merkbare Rückstellkräfte entgegenbietet. Der umgefaltete, obere Beutelrand hat, bedingt durch die Formstabilität des verwendeten Materials, nicht das Bestreben, in seine ursprünglich, offene Form zurückzuspringen. Ein besonders haltbarer Verschluß wird durch mehrmaliges Umfalten erreicht.Now it is possible to close the bag without an additional required bag closure by folding the upper, open edge of the bag once or several times, so that the filled frozen food is secured against inadvertent sliding out. By using a foldable, but dimensionally stable material, the bag can be closed in the simplest way, since the material of the closure strip offers no or imperceptible restoring forces against the folding of the upper, open bag edge. Due to the dimensional stability of the material used, the folded over upper edge of the bag does not endeavor to spring back into its original, open shape. A particularly durable closure is achieved by folding over several times.

Als Material mit ausreichender Formstabilität eignet sich eine Metallfolie, wie z.B. Aluminiumfolie, besonders gut, da sie den gesetzlichen Vorschriften und den hygienischen Anforderungen entspricht und sich außerdem maschinell verarbeiten läßt.A metal foil is suitable as a material with sufficient dimensional stability, e.g. Aluminum foil, particularly good, since it complies with legal regulations and hygienic requirements and can also be processed by machine.

Die Haltbarkeit des Beutelverschlusses läßt sich zusätzlich erhöhen, wenn sich der Verschlußstreifen über beide Beutelwandungen erstreckt.The durability of the bag closure can also be increased if the closure strip extends over both bag walls.

Weiterhin ist durch Aufbringen des Verschlußstreifens auf die Außenseite der Beutelwandung eine einfache Herstellung sowie eine Beschriftbarkeit zwecks Kenntlichmachung des. Beutelinhaltes gewährleistet.Furthermore, by applying the sealing strip to the outside of the bag wall, simple manufacture and labeling can be ensured for the purpose of identifying the contents of the bag.

Weitere, vorteilhafte Ausgestaltungen des Beutels ergeben sich aus der nachfolgenden Beschreibung und den Ansprüchen 6 bis 8.Further advantageous configurations of the bag result from the following description and claims 6 to 8.

Anhand der beiliegenden Zeichnungen, in denen ein bevorzugtes Ausführungsbeispiel dargestellt ist, ist die Neuerung näher erläutert.The innovation is explained in more detail with reference to the accompanying drawings, in which a preferred exemplary embodiment is shown.

Es zeigen:

  • Fig. 1 die Vorderansicht eines unverschlossenen Beutels,
  • Fig. 2 eine der Fig. 1 entsprechende Draufsicht,
  • Fig. 3 die Seitenansicht eines durch zweimaliges Umfalten des oberen Randes geschlossenen Beutels und
  • Fig. 4 die Vorderansicht eines geschlossenen Beutels in einer weiteren Ausführungsform.
Show it:
  • 1 is a front view of an unsealed bag,
  • 2 is a plan view corresponding to FIG. 1,
  • Fig. 3 is a side view of a bag closed by folding the upper edge twice and
  • Fig. 4 is a front view of a closed bag in a further embodiment.

Der in den Fig. 1 bis 4 dargestellte Kunststoffbeutel ist aus einem nahtlosen Schlauchfolienabschnitt 1 hergestellt. An seinem unteren Ende ist der Schlauchfolienabschnitt 1 durch eine quer zu den Beutellängskanten 2 verlaufende, den Boden bildende Verschlußnaht 3 verschlossen. Am oberen, der Verschlußnaht 3 gegenüberliegendem Ende ist der Schlauchfolienabschnitt 1 ringsum mit einem aus einer Metallfolie, z.B. einer Aluminiumfolie hergestellten Verschlußstreifen 4 versehen.The plastic bag shown in FIGS. 1 to 4 is made from a seamless tubular film section 1. At its lower end, the tubular film section 1 is closed by a closure seam 3 which runs transversely to the longitudinal edges 2 of the bag and forms the bottom. At the upper end, opposite the closure seam 3, the tubular film section 1 is encircled with a metal foil, e.g. provided an aluminum foil closure strip 4.

Der Verschlußstreifen 4 kann durch eine geeignete Verbindung, wie z.B. Kleben, Schweißen oder Kaschieren mit dem Schlauchfolienabschnitt 1 verbunden werden. Der Verschlußstreifen 4 ist in den dargestellten Ausführungsbeispielen so auf den Schlauchfolienabschnitt 1 aufgebracht, daß er mit dem oberen, freien Rand des Schlauchfolienabschnittes 1 bündig abschließt. Der Verschlußstreifen 4 erstreckt sich so weit über die Beutellänge, daß durch ein- oder mehrmaliges Umfalten ein dauerhafter Verschluß des Beutels gewährleistet ist. Der Beutel ist deshalb in vorteilhafter Weise auf einer Länge von ca. 3 bis 4 cm, ausgehend von der Einfüllöffnung 5 in Richtung zur Verschlußnaht 2, mit dem Verschlußstreifen 4 versehen.The sealing strip 4 can be connected by a suitable connection, e.g. Gluing, welding or lamination are connected to the tubular film section 1. In the exemplary embodiments shown, the sealing strip 4 is applied to the tubular film section 1 in such a way that it is flush with the upper, free edge of the tubular film section 1. The sealing strip 4 extends so far over the length of the bag that a permanent closure of the bag is ensured by folding it once or several times. The bag is therefore advantageously provided with the sealing strip 4 over a length of approximately 3 to 4 cm, starting from the filling opening 5 in the direction of the sealing seam 2.

Bei dem in der Fig. 4 dargestellten Ausführungsbeispiel sind zur zusätzlichen Sicherung des Beutelverschlusses die oberen Ecken 6 unter einem Winkel von 45° auf den bereits umgefalteten Verschlußstreifen 4 zurückgefaltet.In the embodiment shown in FIG. 4, the upper corners 6 are folded back at an angle of 45 ° onto the already folded closure strip 4 to additionally secure the bag closure.

Bei den in den Fig. 1 bis 4 dargestellten Beuteln handelt es sich um sogenannte Flachbeutel. Es sind jedoch auch andere Beutelformen denkbar.The bags shown in FIGS. 1 to 4 are so-called flat bags. However, other bag shapes are also conceivable.
