Description

Die Erfindung betrifft eine beutelförmige Aufreissverpakkung für einen schnellen Zugang zum Packgut.The invention relates to a bag-shaped tear-open package for quick access to the packaged goods.

Es ist eine Vielzahl von Verpackungen wie Drei-/Vierrandsiegelbeutel, Schlauchbeutel, Seitenfaltenbeutel, Standbodenbeutel bekannt, die durch Kleben, Siegeln oder Schweißen mediendicht aus verschiedenen Materialien, z.B.: aus Mono- oder Verbundmaterialien, hergestellt sind.It's a variety of packaging like three / four-edge sealed bags, Tubular bags, gusseted bags, stand-up pouches known by gluing, sealing or Welding media-tight from different materials, e.g. made from mono or composite materials are.

Die für diese Verpackungen eingesetzten Packstoffe bestehen in der Regel aus Verbundmaterialien, welche die Aufgabe haben, das Produkt hermetisch abzuschirmen und vor allen Dingen die Permeation von Dämpfen und Gasen zu verhindern. Bei diesen Eigenschaften ergibt sich aber auch eine höhere Festigkeit des Packstoffes, weswegen sich diese Verbundmaterialien nur sehr schwierig mit relativ hohem Kraftaufwand ein- und weiterreißen lassen.The packaging materials used for this packaging exist usually made of composite materials that do the job have to hermetically shield the product and before to prevent the permeation of vapors and gases. These properties also result a higher strength of the packaging material, which is why these composite materials are very difficult with relative high effort and let it tear.

Zum Öffnen dieser Verpackungen wird deshalb vielfach ein Schneidwerkzeug wie Schere, Messer, Cutter benötigt, das nachteilig oftmals am Ort des Geschehens nicht zur Verfügung steht. Andererseits können Hilfskonstruktionen wie Einschnitte, Kerben oder Zackenschnitte die vorstehenden Schwierigkeiten mildern, jedoch nicht zufriedenstellend beseitigen.To open this packaging is therefore often a Cutting tools such as scissors, knives, cutters needed that disadvantageously often not available at the scene stands. On the other hand, auxiliary constructions such as Incisions, notches or serrations the above Alleviate difficulties, but not satisfactorily remove.

In gewissen Anwendungsbereichen, z.B. in der Medizin, müssen die eingangs genannten Verpackungen mit Handschuhen geöffnet werden, an denen nicht selten glitschige Produktreste anhaften, so daß die Haltekraft der Finger zum Aufreißen selbst von Kerben nicht ausreicht und die Finger abgleiten.In certain areas of application, e.g. in the medicine, must have the above-mentioned packaging with gloves be opened on which it is not uncommon for slippery Product residues adhere so that the holding force of the fingers not enough to tear open notches and the Slide your fingers.

Eine Verbesserung dieser Situation ist in dem französischen Patent 741.988 beschrieben. Im Siegelrand der bekannten Verpackung ist eine Kerbe vorgesehen, die auf beiden Seiten von jeweils einem Griffloch flankiert ist. Hierdurch wird zwar die Griffigkeit an der Aufreißstelle verbessert, doch läßt sie bei behandschuhten Fingern und gleitfähigem Belag auf dem Handschuh noch zu wünschen übrig.An improvement in this situation is in the French Patent 741,988. In the seal of the well-known A notch is provided on the packaging is flanked on both sides by a finger hole. This does increase the grip at the tear point improved, but leaves it with gloved fingers and slippery surface on the glove still to be desired.

Die WO 94/28837 beschreibt eine andere Lösung dieses Problems, bei der durch Schaffung einer rauhen Oberfläche im Öffnungsbereich der Verpackung das Abgleiten der Finger vermieden wird. Dazu ist jedoch das Anbringen zusätzlicher Fremdmaterialien erforderlich, die einerseits zu einer Verteuerung führen und andererseits das Recyceln der Verpackung erschweren oder gar unmöglich machen.WO 94/28837 describes another solution to this problem, when creating a rough surface in the Opening area of the packaging the sliding of the fingers is avoided. However, this involves attaching additional ones Foreign materials required, on the one hand to a Lead to more expensive and on the other hand the recycling of Make packaging difficult or even impossible.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Verpackung der im Oberbegriff des Hauptanspruches genannten Art zu verbessern und weiter auszubilden, um die vorstehend genannten Schwierigkeiten und technischen Grenzen zu überwinden und insbesondere ohne Verwendung von Hilfsmitteln wie Messer oder Schere ein sicheres und rasches Aufreißen der Pakkung zwecks schnellem Zugang zum Packgut zu ermöglichen.The invention is based on this prior art based on the task of packaging the generic term to improve the main claim and continue to train to the difficulties mentioned above and overcome technical barriers and in particular without using tools such as knives or scissors to safely and quickly open the package to enable quick access to the packaged goods.

Die Lösung der Aufgabe gelingt bei einer Verpackung der eingangs genannten Art mit der Erfindung dadurch, daß die Konturen von Ausstanzungen in Nachbarschaft eines Einschnitts oder einer Kerbe im Siegelbereich zumindest teilweise zackenförmig ausgebildet sind.
Durch die Wahl einer zackenförmigen Kontur der Ausstanzungen wird mit großem Vorteil und in einer sehr unkomplizierten und ökonomisch günstigen Art ein sicherer Kontakt der Finger bei Zugriff mit den Fingerspitzen an der Siegelnaht bzw. den Siegelnähten bewirkt und ein Abgleiten der Fingerspitzen sicher verhindert, so daß das Aufreißen der Verpackung ohne Hilfsmittel wie Messer oder Schere sicher und rasch gelingt.
The object is achieved in a package of the type mentioned at the outset with the invention in that the contours of punched-out areas in the vicinity of an incision or a notch in the sealing area are at least partially jagged.
By choosing a jagged contour of the punched out, a secure contact of the fingers when they are accessed with the fingertips on the sealing seam or the sealing seams is brought about with great advantage and in a very uncomplicated and economically advantageous manner and sliding of the fingertips is reliably prevented, so that Tear open the packaging safely and quickly without tools such as knives or scissors.

Erfindungsgemäß ist hierfür wenigstens eine Ausstanzung vorgesehen, bevorzugt können jedoch auch zwei Ausstanzungen rechts- und linksseitig von der Schwächung vorgesehen sein.According to the invention, there is at least one punched-out for this provided, but preferably also two punched-outs provided on the right and left side of the weakening his.

Ausgestaltungen der Erfindung sind entsprechend den Merkmalen der Unteransprüche vorgesehen.Embodiments of the invention are in accordance with the features of the subclaims provided.

Weist eine Verpackung beispielsweise zu einer Quernaht eine zusätzliche Längsnaht auf, kann die Ausstattung im Überlappungsbereich von Längs- und Quernaht vorgesehen sein.For example, a package points to a transverse seam an additional longitudinal seam, the equipment in Overlap area of longitudinal and transverse seams provided his.

Wird eine Ausstanzung mit geschlossener Stanzlinie gewählt, so entsteht eine offene Lochung der Siegelnaht. Bei nicht geschlossener Stanzlinie verbleibt der Stanzling am Stanzort und kann scharnierartig aus der Stanzebene bewegt werden, wodurch die Funktion einer Anfass- und Öffnungshilfe ebenfalls erfüllt wird. Bevorzugt ist die Ausstanzung kreisförmig, sie kann aber auch polygonal oder streifenförmig sein. If a punch with a closed punch line is selected, this creates an open perforation in the sealed seam. If the punch line is not closed, the punch remains at the punching location and can be hinge-like from the punching plane be moved, whereby the function of a touch and opening aid is also fulfilled. Is preferred the cutout is circular, but it can also be polygonal or be strip-shaped.

Vorzugsweise weist die Stanzung eine Größe auf, die den Eingriff eines menschlichen Fingers zuläßt. Zumindest soll ihre Größe der Tastfläche einer menschlichen Fingerkuppe entsprechen.The stamping preferably has a size which corresponds to the Intervention of a human finger. At least supposed to be the size of the tactile surface of a human fingertip correspond.

In allen Fällen ist die Kontur der Ausstanzung zumindest teilweise zackenförmig ausgelegt, womit eine signifikante Verbesserung als Anfaß- und Öffnungshilfe verwirklicht ist. Der Effekt kann noch dadurch verstärkt werden, daß die Zacken aus der Ebene der Stanzung herausgebogen werden und damit ein erheblich verstärktes Gleithemmnis bilden.In all cases, the contour of the punch is at least partially jagged, making it a significant one Improvement realized as a handle and opening aid is. The effect can be enhanced by the fact that the teeth are bent out of the plane of the punching and thus form a significantly increased sliding barrier.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus der nachstehenden Erläuterung eines in der Zeichnung dargestellten Ausführungsbeispieles.Further details and advantages of the invention emerge derive from the explanation below one in the Drawing shown embodiment.

  • Fig. 3 eine Ansicht einer gezackten Ausstanzung im Kreuzungsbereich einer Quer- und Längsnaht.
  • Show it:
  • 1 is a view of a part of a bag-shaped packaging with a transverse sealing seam and a notch, and two punchings on the side thereof,
  • 2 shows a section through the area of the punching out along the sectional plane II-II in FIG. 3,
  • Fig. 3 is a view of a jagged punch in the intersection of a transverse and longitudinal seam.
  • Das Ausführungsbeispiel gemäß Fig. 1 zeigt einen Teilabschnitt einer beutelförmigen Aufreissverpackung (20) mit einer in dessen Querseite angeordneten Quersiegelnaht (1). Diese weist als Aufreisshilfe eine Kerbe (3) auf. Zu beiden Seiten dieser Kerbe (3) sind als zusätzliche Anfass - und Öffnungshilfen Ausstanzungen (5) vorgesehen. The exemplary embodiment according to FIG. 1 shows a partial section a bag-shaped tear-open package (20) with a transverse sealing seam arranged in its transverse side (1). As a tear-open aid, this has a notch (3). To Both sides of this notch (3) are as an additional handle - And opening aids punched out (5) provided.

    Diese weisen in erfindungswesentlicher Ausbildung an ihren Rändern (4) mindestens zum Teil eine zackenförmige Kontur (6) auf. Dadurch wird beim Anfassen - anders als bei glatten Rändern - eine signifikante Verbesserung der Gleithemmung in einer unkomplizierten und ökonomisch günstigen Art und ein sicherer Kontakt der Finger beim Zugriff erreicht und ein Abgleiten der Fingerspitzen verhindert, so daß das Aufreissen der Verpackung (20) ohne Hilfsmittel wie Messer oder Schere sicher und rasch gelingt. Dabei wird das Packgut (10) sofort freigelegt und kann entnommen werden.
    Fig. 2 zeigt von der Seite den aufgerissenen Packbeutel (20) mit dem darin enthaltenen Packgut (10) in entnahmebereitem Zustand.
    Darin ist die Ausstanzung (5) im Schnittbild zu erkennen, die am Rande (4) mit zackenförmiger Kontur (6) ausgebildet ist. Diese ist in einer besonders griffigen Art und Weise zumindest teilweise aus der Ebene der Randsiegelnaht (1) herausgebogen.
    In der Figur 3 ist eine Teilansicht der Verpackung nach der Erfindung (20) mit einer Ausstanzung (5) im Überlappungsbereich der Quersiegelnaht (1) mit einer Längssiegelnaht dargestellt. Deutlich erkennbar ist der nach vorn aus der Ebene der Naht (2) herausgebogene Zackenrand (6).Die Ausstanzung weist dabei eine Größe auf, die beispielsweise den Eingriff eines menschlichen Fingers zulässt. Zumindest soll die Größe der Ausstanzung (5) der Tastfläche einer menschlichen Fingerkuppe entsprechen. Eine derartige Ausstanzung (5) kann kreisförmig, sie kann aber auch polygonal oder streifenförmig sein.
    Nach allem ist aus der Zeichnung und den Beschreibungen entnehmbar, dass die Erfindung wirkungsvoll, unkompliziert und äußerst ökonomisch ist. Ein Abgleiten der Finger wird auch beim Tragen von Handschuhen und anhaftendem schmierendem Material sicher verhindert, so daß das spontane Aufreissen einer erfindungsgemäss ausgerüsteten Verpackung z. B. im OP unter den dort herrschenden erschwerten Bedingungen sicher und rasch gelingt.
    Insofern löst die Erfindung in optimaler Weise die eingangs gestellte Aufgabe.
    In an embodiment essential to the invention, these have at least in part a serrated contour (6) on their edges (4). As a result, when touching - unlike smooth edges - a significant improvement in the slip resistance is achieved in an uncomplicated and economically favorable manner and a safe contact of the fingers during access and a sliding of the fingertips is prevented, so that the packaging (20) tears open without aids like knives or scissors succeeds safely and quickly. The packaged goods (10) are immediately exposed and can be removed.
    Fig. 2 shows from the side the torn packing bag (20) with the packaged goods (10) contained therein in the ready for removal state.
    This shows the cut-out (5) in the sectional image, which is formed on the edge (4) with a serrated contour (6). This is at least partially bent out of the plane of the edge sealing seam (1) in a particularly handy manner.
    FIG. 3 shows a partial view of the packaging according to the invention (20) with a punched-out area (5) in the overlap area of the transverse sealing seam (1) with a longitudinal sealing seam. The serrated edge (6), which is bent forwards out of the plane of the seam (2), can be clearly seen. The punched-out area is of a size which, for example, allows the intervention of a human finger. At least the size of the punched-out area (5) should correspond to the tactile area of a human fingertip. Such a punch (5) can be circular, but it can also be polygonal or strip-shaped.
    After all, it can be seen from the drawing and the descriptions that the invention is effective, uncomplicated and extremely economical. Slipping of the fingers is reliably prevented even when wearing gloves and adhesive lubricating material, so that the spontaneous tearing open of a package equipped according to the invention, for. B. succeeds safely and quickly in the operating room under the difficult conditions prevailing there.
    In this respect, the invention optimally achieves the object stated at the outset.
