Description

Die Erfindung betrifft einen Verschlußstreifen für Beutel bestehend aus einem länglichen flachen Streifenteil mit verstärkten Längsrändern, wobei der Verschlußstreifen ausschließlich aus Kunststoff besteht.The invention relates to a closure strip for bags consisting of an elongated flat strip part with reinforced longitudinal edges, the closure strip consisting exclusively of plastic.

Verschlußstreifen, die auch als Clip-Verschlüsse bezeichnet werden, dienen zum Verschließen von Beuteln von Hand oder mittels einer Verpackungsmaschine. Dabei werden die einzelnen Verschlußstreifen durch Ablängen aus Bandmaterial gewonnen.Closure strips, which are also referred to as clip closures, are used to close bags by hand or by means of a packaging machine. The individual sealing strips are obtained by cutting to length from tape material.

Ein Verschlußstreifen der eingangs genannten Art ist aus der EP 0401526 A1 bekannt. Dieser Verschlußstreifen weist die Form eines flachen länglichen Streifens mit verstärkten Längsrändern auf und besteht ausschließlich aus einem flexiblen Kunststoff. Dieser Streifen ist zum Zwecke der Ausbildung von Soll-Knickfalten an zwei mit Abstand voneinander und von seinen beiden Enden liegenden Stellen der Streifen über seine gesamte Breite geschwächt, wobei die verstärkten Längsränder an diesen Stellen Aussparungen aufweisen. Hierdurch wird es möglich, daß sich der Clip-Verschluß mit geringem Aufwand an einem Beutel anbringen läßt, welcher auch der Strahlung von Mikrowellen ausgesetzt sein kann, da störende Metallteile nicht vorhanden sind.A closure strip of the type mentioned is known from EP 0401526 A1. This sealing strip is in the form of a flat, elongated strip with reinforced longitudinal edges and consists exclusively of a flexible plastic. This strip is for the purpose of Formation of predetermined folds at two points at a distance from each other and from its two ends weakened the strips over its entire width, the reinforced longitudinal edges having recesses at these points. This makes it possible that the clip closure can be attached to a bag with little effort, which can also be exposed to the radiation from microwaves, since there are no interfering metal parts.

Andererseits läßt sich dieser Clip-Verschluß wegen seiner Aussparungen an den verstärkten Längsrändern zwar leicht und flach umfalten, so daß sich der Beutel auf einfache Weise verschließen läßt. Es hat sich aber gezeigt, daß ein Clip-Verschluß dieser Art insofern verbesserungsbedürftig ist, als einerseits durch die festgelegte Beabstandung der Soll-Knickstellen eine Anpassung an unterschiedliche Beutelöffnungen aufwendig ist und andererseits die Verschlußsicherheit nicht immer gegeben ist.On the other hand, because of its recesses on the reinforced longitudinal edges, this clip closure can be folded over easily and flatly, so that the bag can be closed in a simple manner. It has been shown, however, that a clip closure of this type is in need of improvement insofar as, on the one hand, an adaptation to different bag openings is complex due to the fixed spacing of the desired kink points and, on the other hand, the closure security is not always given.

Daher liegt der Erfindung die Aufgabe zugrunde, einen Verschlußstreifen der eingangs genannten Art dahingehend zu verbessern, daß er auf unterschiedliche Beutelabmessungen anwendbar ist und stets ein sicheres Verschließen gewährleistet.The invention is therefore based on the object of improving a closure strip of the type mentioned at the outset in such a way that it can be used for different bag dimensions and always ensures secure closure.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß auf der einen Seite des Streifenteils ein erster Längsrand und auf der anderen Seite des Streifenteils ein zweiter Längsrand vorgesehen ist, wobei jeder Längsrand angeformte Verbindungsmittel aufweist derart, daß beim Umlegen des Verschlußstreifens um die Beutelöffnung ein Abschnitt des ersten Längsrandes formschlüssig mit einem Abschnitt des zweiten Längsrandes verbindbar ist.This object is achieved in that a first longitudinal edge is provided on one side of the strip part and a second longitudinal edge is provided on the other side of the strip part, each longitudinal edge having integrally formed connecting means such that when the closure strip is folded around the bag opening, a section of the first Longitudinal edge is positively connected to a portion of the second longitudinal edge.

Die erfindungsgemäße Lösung zeichnet sich dadurch aus, daß die Länge des Abschnittes, in dem die Längsränder beim Umfalten um die Beutelöffnung miteinander verbunden werden, variabel ist. Daneben stehen die Längsrandabschnitte auf der gesamten Verschlußlänge formschlüssig miteinander in Verbindung, so daß ein sicheres Verschließen ebenso gegeben ist wie die Möglichkeit, den Beutel wieder einfach durch Lösen der formschlüssigen Verbindung zu öffnen.The solution according to the invention is characterized in that the length of the section in which the longitudinal edges are connected to one another when folded around the bag opening is variable. In addition, the longitudinal edge sections are positively connected to one another over the entire length of the closure, so that there is a secure closure as well as the possibility of simply opening the bag again by releasing the positive connection.

Eine besonders vorteilhafte Gestaltung ergibt sich dann, wenn auf der einen Seite des Streifenteils Gruppen von ersten Längsrändern und auf der anderen Seite des Streifenteils Gruppen von zweiten Längsrändern vorgesehen sind, wobei jeweils zu unterschiedlichen Gruppen gehörige Längsränder abschnittsweise miteinander verbindbar sind. Hierdurch wird die Haltbarkeit des Verschlusses wesentlich verbessert, da sich die einzelnen Längsränder hinsichtlich ihrer Verschlußwirkung gegenseitig unterstützen.A particularly advantageous design is obtained if groups of first longitudinal edges are provided on one side of the strip part and groups of second longitudinal edges are provided on the other side of the strip part, with longitudinal edges belonging to different groups being connectable to one another in sections. This significantly improves the durability of the closure, since the individual longitudinal edges mutually support one another with regard to their closure effect.

Eine besonders einfache Gestaltung ergibt sich, wenn jede Gruppe aus zwei Längsrändern besteht.A particularly simple design results if each group consists of two longitudinal edges.

Wenn die miteinander verbindbaren Längsränder in Querrichtung des Streifenteils zueinander versetzt sind, so daß die angeformten Verbindungsmittel durch in Querrichtung ausgebildete Vorsprünge und Ausnehmungen gebildet sind, wobei der Vorsprung des einen Längsrandes in die Ausnehmung des anderen Längsrandes und der Vorsprung des anderen Längsrandes in die Ausnehmung des einen Längsrandes einrastbar ist, wird der Fertigungsaufwand für den Verschlußstreifen herabgesetzt, da jedes aus Vorsprung und Ausnehmung bestehende Verbindungsmittel gleich gestaltet ist und einstückig an den jeweiligen Langsrand angeformt sein kann.If the interconnectable longitudinal edges are offset from one another in the transverse direction of the strip part, so that the integrally formed connecting means are formed by projections and recesses formed in the transverse direction, the projection of one longitudinal edge into the recess of the other longitudinal edge and the projection of the other longitudinal edge into the recess of the a longitudinal edge can be snapped in, the manufacturing effort for the closure strip is reduced, since each connecting means consisting of a projection and a recess is of the same design and can be integrally formed on the respective longitudinal edge.

Wenn gemäß einer besonderen konstruktiven Gestaltung jeder Vorsprung einen sich an ein viertelrundes Profil des Längsrandes anschließenden halbkreisförmigen Ansatz aufweist, welcher unter Begrenzung der Ausnehmung zum Streifenteil beabstandet ist, ergibt sich ein an die Erfordernisse der Massenproduktion gut angepaßter Verschlußstreifen. Wenn die Vorsprünge miteinander verbindbarer Längsränder in Querrichtung zueinander weisen, ist die Haltbarkeit der Verbindung besonders gut.If, according to a special constructive design, each projection has a semicircular projection which adjoins a quarter-round profile of the longitudinal edge and which is spaced apart from the strip part by limiting the recess, this results in a closure strip which is well adapted to the requirements of mass production. If the projections of interconnectable longitudinal edges point in the transverse direction to one another, the durability of the connection is particularly good.

Hinsichtlich der Materialeigenschaften des Verschlußstreifens ergibt sich dann eine besonders gute Stabilität des Verschlußstreifens, wenn dieser ausschließlich aus einem Kunststoffgemisch aus Polypropylen und Talkum besteht, wobei vorzugsweise der Anteil von Talkum etwa 30 Prozent betragen sollte. Die Stabilität wirkt sich dabei vorteilhaft im Verpackungsvorgang auf der Verpackungsmaschine aus, wobei zunächst vor dem Einlegen des Beutels die beiden äußeren Bereiche eines Verschlußstreifens zu einem U-Profil gebogen werden, anschließend der zu verschließende Beutel in das U-Profil eingelegt wird und nacheinander der erste und dann der zweite Steg des U-Profils auf den Beutel geklappt werden und unter Druck die formschlüssige Verbindung der miteinander verbindbaren Längsränder hergestellt wird.With regard to the material properties of the sealing strip, there is particularly good stability of the sealing strip if it consists exclusively of a plastic mixture of polypropylene and talc, the proportion of talc should preferably be about 30 percent. The stability has an advantageous effect in the packaging process on the packaging machine, the two outer regions of a sealing strip being bent into a U-profile first before the bag is inserted, then the bag to be closed is inserted into the U-profile and the first one in succession and then the second web of the U-profile can be folded onto the bag and the positive connection of the interconnectable longitudinal edges is produced under pressure.

Die Erfindung wird im folgenden anhand einer ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert.The invention is explained in more detail below with the aid of a drawing representing an exemplary embodiment.

Der Verschlußstreifen besteht aus einem flachen Streifenteil 1 mit bestimmter Breite. Im Randbereich des Verschlußstreifens 1 sind auf der oberen Seite des flachen Streifenteils 1 Längsränder 2a,2b einstückig angeformt, die das Streifenteil in seiner Breite begrenzen und nach innen gerichtete Vorsprünge 3a,3b aufweisen. Diese Vorsprünge 3a,3b sind von der Oberseite des Streifenteils 1 beabstandet und schließen hiermit Ausnehmungen 4a,4b ein.The sealing strip consists of a flat strip part 1 with a certain width. In the edge region of the closure strip 1, longitudinal edges 2a, 2b are integrally formed on the upper side of the flat strip part 1, which limit the width of the strip part and have inward projections 3a, 3b. These projections 3a, 3b are spaced from the top of the strip part 1 and hereby enclose recesses 4a, 4b.

Auf der unteren Seite des Streifenteils 1 befinden sich in Querrichtung zu den Längsrändern 2a,2b versetzte Längsränder 2c,2d, deren Vorsprünge 3c,3d voneinander weg gerichtet sind.On the lower side of the strip part 1 there are longitudinal edges 2c, 2d offset in the transverse direction to the longitudinal edges 2a, 2b, the projections 3c, 3d of which are directed away from one another.

Die Profile der jeweiligen Längsrander 2a-2d sind gleich gestaltet und bestehen aus einem viertelrundem Profil, an welches sich ein halbkreisförmiger Ansatz 3a-3d anschließt, an welchen sich wiederum eine ebenfalls etwa viertelrunde Ausnehmung 4a-4d anschließt.The profiles of the respective longitudinal edges 2a-2d have the same design and consist of a quarter-round profile, which is followed by a semicircular projection 3a-3d, which in turn is followed by an approximately quarter-round recess 4a-4d.

Die Funktion des erfindungsgemäßen Verschlußstreifens ist derart, daß sich nach Umlegen des Verschlußstreifens um den zu verschließenden Beutel die Vorsprünge 3c,3d der unteren Längsränder 2c,2d in die Ausnehmungen 4a,4b der oberen Längsränder 2a,2b formschlüssig einrasten lassen. Dies geschieht dadurch, daß der abgelängte Verschlußstreifen zunächst zu einem U-Profil aufgebogen wird und daß unter Einschluß des Beutels zunächst der eine Schenkel des U-Profils flach auf den Beutel gelegt wird und anschließend der zweite Schenkel derart unter Druck aufgelegt wird, daß die formschlüssige Verbindung der einander zugeordneten Längsränder erreicht wird.The function of the closure strip according to the invention is such that after the closure strip has been folded around the bag to be closed, the projections 3c, 3d of the lower longitudinal edges 2c, 2d can be positively latched into the recesses 4a, 4b of the upper longitudinal edges 2a, 2b. This is done in that the cut-to-length sealing strip is first bent up to a U-profile and that, including the bag, first one leg of the U-profile is placed flat on the bag and then the second leg is placed under pressure such that the form-fitting Connection of the mutually assigned longitudinal edges is achieved.
