Abstract

The package consists of a web of paper and a plastic film which are both sealed together at the edge. The sealing consists of narrow, elongated sealing elements which have a limited length. The narrow elongated sealing elements can have various dimensions and be arranged in parallel or at angles relative to one another. Smaller sealing elements may be provided next to the narrow elongated sealing elements. Creasing of the plastic film is avoided and tightness increased by the spacings between the sealing elements, particularly in the case of articles with complex shapes being packaged.

Description

Die Erfindung betrifft eine Verpackung, z.B. für chirurgische Instrumente, aus einer Kunststoffolienbahn und einer Papierbahn, die beide am Rand, der einen in der Kunststoffolienbahn eingeformten Aufnahmeraum umschließt, miteinander versiegelt sind, mit einer Ansatzstelle für einen Öffnungsvorgang, bei dem die Bahnen entlang des Randes voneinander abziehbar sind, wobei der Rand mindestens eine Gruppe von schmalen, länglichen Siegelungselementen aufweist, die gleichförmig verteilt sind.The invention relates to packaging, for example for surgical instruments, made of a plastic film web and a paper web, both of which are sealed to one another at the edge, which encloses a receiving space formed in the plastic film web, with a starting point for an opening process, in which the webs run along the edge are peelable from one another, the edge having at least one group of narrow, elongated sealing elements which are uniformly distributed.

Bei der Verpackung von chirurgischen Instrumenten, Spritzen u. ä. kommt es darauf an, daß die Waren in der Verpackung auch bei längerer Lagerung steril bleiben und auch nach dem Öffnungsvorgang nicht durch ausge­rissene Papierfasern verunreinigt werden. Eine solche Ver­packung, insbesondere für Instrumente zum einmaligen Verbrauch, ist aus der DE-OS 34 27 702 bekannt.When packaging surgical instruments, syringes, etc. It is important that the goods remain sterile in the packaging even after prolonged storage and that they are not contaminated by torn paper fibers even after opening. Such packaging, in particular for instruments for single use, is known from DE-OS 34 27 702.

Dort werden die Waren in eine vorgeformte, der Ware angepaßte, tiefgezogene Vertiefung einer Kunststoffolie eingebracht, und mit einer Papierbahn versiegelt. Die Versiegelung erfolgt dabei so, daß die ʺpeelʺ-Fähigkeit beim Öffnen erhalten bleibt und eine ausreichende Dichtig­keit gegen eindringende Keime, Schmutz u. dgl. erreicht wird. Die schmalen länglichen Siegelungselemente bewirken dabei den mechanischen Zusammenhalt der Papierbahn mit der Kunststoffolie. Nach dem Versiegeln wird die fertigver­packte Ware dem Sterilisierungsvorgang unterworfen, bei dem die Keime durch entsprechende Begasung mit einem geeigneten Gas abgetötet werden. Beim Öffnen der Ver­packung werden Papierbahn und Kunststoffolie durch Ab­peelen voneinander getrennt, was durch die Gestalt der Siegelungselemente erleichtert wird. Die Abziehrichtung entspricht dabei in der Regel der Hauptfaserrichtung des Papiers.There the goods are introduced into a preformed, deep-drawn depression of a plastic film, adapted to the goods, and sealed with a paper web. The sealing is done in such a way that the ʺpeelʺ ability is retained when opening and sufficient sealing against the ingress of germs, dirt and the like. Like. Is achieved. The narrow, elongated sealing elements bring about the mechanical cohesion of the paper web with the plastic film. After sealing, the packaged goods are subjected to the sterilization process, in which the germs are killed by appropriate gassing with a suitable gas. When the packaging is opened, the paper web and plastic film are peeled apart from each other, which is facilitated by the shape of the sealing elements. The pull-off direction usually corresponds to the main fiber direction of the paper.

Bei größeren zu verpackenden Waren ergibt sich beim Vorformen der Vertiefung das Problem, daß die ebene Fläche der Kunststoffolie weitgehend verloren geht. Das kann beim Versiegeln der Verpackung zu Störungen führen, sei es, daß Falten beim Versiegeln entstehen, oder auch, daß die Versiegelung nicht dicht genug gegen eindringende Keime ist.In the case of larger goods to be packaged, the problem arises when preforming the depression that the flat surface of the plastic film is largely lost. This can lead to malfunctions when the packaging is sealed, be it that folds occur during the sealing process or that the sealing is not sufficiently tight against the ingress of germs.

Da der Rand der Verpackung nicht übermäßig groß werden soll, muß dort auf geringer Breite eine absolut zuverlässige Versiegelung erreicht werden, die auch durch Spannungen in der Kunststoffolie nicht beeinträchtigt werden darf.Since the edge of the packaging should not be excessively large, there must be an absolute small width reliable sealing can be achieved, which must not be affected by tensions in the plastic film.

In der FR-A-15 76 587 ist eine Anordnung zur Aufnahme von zur Aussaat bestimmten Samen beschrieben. Die Samen werden dabei zwischen zwei Folien angeordnet, wobei die Folien beispiels­weise aus papierähnlichem Material bestehen. Die beiden Folien sind durch eine Vielzahl kleiner, länglicher Schweiß- oder Druckstellen miteinander verbunden, wobei die Schweiß- oder Druckstellen kurz sind und eine längliche Gestalt besitzen. Bei einer Einrichtung dieser Art kommt es aber auf eine be­sondere Dichtheit der Verbindungen zwischen den beiden Folien nicht an, da die Folien selbst durchlässig sein müssen, um das Keimen der Samen nicht zu behindern.FR-A-15 76 587 describes an arrangement for receiving seeds intended for sowing. The seeds are arranged between two foils, the foils being made of paper-like material, for example. The two foils are connected to one another by a large number of small, elongated welding or pressure points, the welding or pressure points being short and having an elongated shape. With a device of this type, however, a special tightness of the connections between the two foils is not important, since the foils themselves must be permeable in order not to hinder the germination of the seeds.

Die Erfindung hat es sich zur Aufgabe gemacht, eine Verpackung z.B. für chirurgische Instrumente zu schaffen, die auch bei solchen Vertiefungen der Kunststoffolienbahn, die zu einer Verformung der Folienbahn führen, eine absolut dichte Ver­siegelung ermöglicht.The invention has set itself the task of e.g. to create for surgical instruments which, even with such depressions in the plastic film web, which lead to a deformation of the film web, enables an absolutely tight seal.

Zur Lösung dieser Aufgabe geht die Erfindung aus von der Ver­packung der eingangs angegebenen Gattung und schlägt vor, daß die länglichen Siegelungselemente zwischen den Begrenzungen des Randes Unterbrechungen aufweisen, derart, daß die einzel­nen, länglichen Siegelungselemente zwischen den Begrenzungen enden, daß jedoch die einzelnen Siegelungselemente mit kleinem Abstand aneinander anschließen, wobei der Abstand wesentlich kleiner ist als die Länge der Siegelungselemente.To achieve this object, the invention is based on the packaging of the type specified at the outset and proposes that the elongated sealing elements between the boundaries of the edge have interruptions such that the individual, elongated sealing elements end between the boundaries, but that the individual sealing elements also Connect a small distance to each other, the distance being significantly smaller than the length of the sealing elements.

Die erfindungsgemäße Verpackung hat den besonderen Vorteil, daß die durch Tiefziehen eventuell leicht verwölbte Kunst­ stoffolie in den Unterbrechungen zwischen den einzelnen Längs­siegelungselementen ausweichen kann und keine Falten wirft. In der Folie beim Versiegeln auftretende Spannungen können sich ausgleichen. Dabei können die einzelnen Siegelungselemente direkt in Linien hintereinander angeordnet werden. Es ist aber auch eine leicht versetzte Anordnung möglich.The packaging according to the invention has the particular advantage that the art, which may be slightly warped by deep drawing can dodge in the interruptions between the individual longitudinal sealing elements and does not wrinkle. Tensions that occur in the film during sealing can even out. The individual sealing elements can be arranged directly in lines one behind the other. However, a slightly offset arrangement is also possible.

Bei einer bevorzugten Ausführungsform der Erfindung sind die länglichen Siegelungselemente parallel zueinander angeordnet. Bei dieser Ausführungsform wird schon durch die länglichen Siegelungselemente eine gute Dichtigkeit erreicht und der Öff­nungsvorgang ist besonders einfach, da sich die Packung ohne Rucken öffnen läßt.In a preferred embodiment of the invention, the elongate sealing elements are arranged parallel to one another. In this embodiment, a good seal is achieved by the elongate sealing elements and the opening process is particularly simple, since the package can be opened without jerking.

Bei einer anderen Ausführungsform der Erfindung sind die ein­zelnen Siegelungselemente abgewinkelt. Dabei können die Siege­lungselemente selbst gewinkelt sein oder sie sind winklig zueinander angeordnet. Bei dieser Anordnung ist die Dichtig­keit besonders hoch, vor allem dann, wenn die Siegelungs­elemente, wie auch in den anderen Ausführungsformen, dicht nebeneinander liegen.In another embodiment of the invention, the individual sealing elements are angled. The sealing elements themselves can be angled or they are arranged at an angle to one another. In this arrangement, the tightness is particularly high, especially when the sealing elements, as in the other embodiments, lie close together.

Vorteilhaft ist es auch, wenn die länglichen Siegelungs­elemente unterschiedliche Länge und/oder Breite aufweisen. Besonders diese Ausführungsform ermöglicht der tiefgezogenen Kunststoffolie ein gutes Ausweichen, so daß die Nachteile einer Verwölbung vermieden wird. Auch die Dichtigkeit ist aus­gezeichnet, besonders wenn die einzelnen Siegelungselemente sehr dicht beieinander liegen.It is also advantageous if the elongate sealing elements have different lengths and / or widths. In particular, this embodiment enables the deep-drawn plastic film to yield well, so that the disadvantages of warping are avoided. The tightness is also excellent, especially when the individual sealing elements are very close together.

Weiter hat es sich als vorteilhaft erwiesen, wenn eine zweite Gruppe von annähernd punktförmigen Siegelungselementen mit im Vergleich zu den länglichen Siegelungselementen kleinen Ab­messungen gleichmäßig über den Rand verteilt ist. Eine Kombi­nation aus diesen beiden verschiedenen Siegelungselementen bringt eine besonders hohe Dichtigkeit. Dabei können die läng­lichen Siegelungselemente relativ weit auseinander liegen, da die Dichtigkeit durch die kleinen Siegelungselemente, die dicht an dicht liegen, gewährleistet wird. Da diese zweite Gruppe von Siegelungselementen klein und punktförmig ist, besteht keine Gefahr, daß in der Kunststoffolie Spannungen auftreten, auch wenn das Verpackungsgut relativ komplizierte Umrisse aufweist.It has also proven to be advantageous if a second group of approximately punctiform sealing elements with Compared to the elongated sealing elements small dimensions is evenly distributed over the edge. A combination of these two different sealing elements provides a particularly high level of tightness. The elongated sealing elements can be relatively far apart since the tightness is ensured by the small sealing elements, which lie close together. Since this second group of sealing elements is small and punctiform, there is no danger that tensions will occur in the plastic film, even if the packaged goods have relatively complicated outlines.

In the drawing, some embodiments of the invention are shown schematically. Show it :
  • 1 is a plan view of a package in training according to the invention,
  • 2 is a plan view of part of another embodiment of the invention on a greatly enlarged scale,
  • 3 is a plan view of part of a further embodiment of the invention on a greatly enlarged scale,

  • Fig. 5 is a plan view of part of another embodiment of the invention and
  • Fig. 6 is an enlarged section through part of a package according to the invention.

Die Verpackung besteht im wesentlichen aus der Papierbahn 5 und der Kunststoffolie 6, die beide am Rand 4 miteinander ver­siegelt sind. Die innere Begrenzung des Randes 4 ist mit 15 und die äußere Begrenzung mit 14 bezeichnet. Die innere Be­grenzung 15 umschließt den Aufnahmeraum 13, der, wie an sich bekannt, durch eine Vertiefung in der Kunststoffolie 6 ge­bildet ist und die Ware 7 aufnimmt.The packaging consists essentially of the paper web 5 and the plastic film 6, both of which are sealed together at the edge 4. The inner boundary of the edge 4 is designated 15 and the outer boundary 14. The inner boundary 15 encloses the receiving space 13, which, as is known per se, is formed by a recess in the plastic film 6 and receives the goods 7.

Der Rand 4 der Verpackung weist die länglichen Sie­gelungselemente 1 auf. Die länglichen Siegelungselemte 1 besitzen eine begrenzte Länge und werden von den Abstän­den 2 unterbrochen.The edge 4 of the packaging has the elongated sealing elements 1. The elongated sealing elements 1 have a limited length and are interrupted by the distances 2.

Die Fig. 1 zeigt außerdem die punktförmigen Siegelungs­elemente 3. Diese punktförmigen Siegelungselemente 3 sind zwischen den länglichen Siegelungselementen 1 angeordnet und erhöhen die Dichtigkeit der Verpackung. Bei kompli­zierter geformten Waren 7 neigt die Kunststoffolie 6 dazu, am Rand beim Versiegelungsvorgang Falten zu werfen. Durch die Abstände 2 zwischen den länglichen Siege­lungselementen 1 werden die Wölbungen in der Kunst­stoffolie 6 ausgeglichen und die Faltenbildung am Rand 4 vermieden.1 also shows the punctiform sealing elements 3. These punctiform sealing elements 3 are arranged between the elongate sealing elements 1 and increase the tightness of the packaging. In the case of more complicated shaped goods 7, the plastic film 6 tends to crease at the edge during the sealing process. Due to the distances 2 between the elongate sealing elements 1, the curvatures in the plastic film 6 are compensated for and the formation of folds at the edge 4 is avoided.

Die Fig. 2 zeigt eine parallel versetzte Anordnung der länglichen Siegelungselemente 1. Bei einer solchen Anordnung, bei der die Siegelungselemente 1 dicht an dicht nebeneinander liegen, wird schon durch die länglichen Siegelungselemente allein eine befriedigende Dichtheit der Verpackung erreicht. Eine solche Ausfüh­rungsform, wie sie in Fig. 2 gezeigt ist, ist besonders einfach herzustellen.FIG. 2 shows a parallel offset arrangement of the elongate sealing elements 1. In such an arrangement, in which the sealing elements 1 lie close together, the elongate sealing elements alone achieve a satisfactory tightness of the packaging. Such an embodiment, as shown in Fig. 2, is particularly easy to manufacture.

Auch in Fig. 3 sind die länglichen Siegelungselemente 1 gegeneinander versetzt angeordnet und stehen winklig zueinander. Der Winkel kann beliebig gewählt werden. Eine Erhöhung der Dichtheit der Verpackung wird durch die punktförmigen Siegelungselemente 3 erreicht.3, the elongated sealing elements 1 are also offset from one another and are at an angle to one another. The angle can be chosen arbitrarily. The punctiform sealing elements 3 increase the tightness of the packaging.

Bei der Fig. 4 sind winklig geformte längliche Siegelungs­elemente 8 gezeigt. Diese winkligen Siegelungselemente 8 werden versetzt gegeneinander angeordnet und ihre Dich­tungswirkung durch die punktförmigen Siegelungsele­mente 3 unterstützt.4, angularly shaped elongate sealing elements 8 are shown. These angled sealing elements 8 are offset from one another and their sealing effect is supported by the punctiform sealing elements 3.

Die Fig. 5 zeigt eine Anordnung von länglichen Siege­lungselementen von verschiedener Länge und Breite. Die größeren länglichen Siegelungselemente 1 wechseln ab mit kleineren Siegelungselementen 9. Eine Aufreißlasche 10 er­leichtert den Öffnungsvorgang.5 shows an arrangement of elongate sealing elements of different lengths and widths. The larger elongated sealing elements 1 alternate with smaller sealing elements 9. A tear tab 10 facilitates the opening process.

Die Fig. 6 zeigt einen stark vergrößerten und zeich­nerisch überhöhten Schnitt durch einen Teil einer Verpackung mit einer Papierbahn 5 und einer Kunst­stoffolie 6. Der Verlauf der Fasern 11 ergibt sich durch die Herstellung. Da die Kontaktfläche 12 der Siegelungs­elemente 1 auf den einzelnen Fasern 11 im Vergleich zu deren Länge gering ist, besteht keine Gefahr des Heraus­ziehens der Fasern 11 aus dem Faserverband in der Papierbahn 5. Dabei ist es gleichgültig, in welcher Richtung zur Papierbahn bezüglich deren Hauptfaser­richtung sich die Aufreißlasche 10 befindet. Günstig ist es, wenn in der Draufsicht die Längsrichtung der Siegelungselemente 1 mit der Hauptlängsrichtung der Fasern 11 einen spitzen Winkel bildet.FIG. 6 shows a greatly enlarged and drawing-exaggerated section through part of a package with a paper web 5 and a plastic film 6. The course of the fibers 11 results from the production. Since the contact surface 12 of the sealing elements 1 on the individual fibers 11 is small compared to their length, there is no risk of pulling the fibers 11 out of the fiber structure in the paper web 5. It does not matter in which direction to the paper web with respect to its main fiber direction the pull tab 10 is located. It is advantageous if the longitudinal direction of the sealing elements 1 forms an acute angle with the main longitudinal direction of the fibers 11 in the plan view.
