Description

Die Erfindung betrifft eine Weichpackung aus einer Kunststoffolie für Zellstofferzeugnisse, insbesondere für die Aufnahme von Papiertaschentüchern, mit im wesentlichen quaderförmigem Aufbau unter Bildung von Vorderwand, Rückwand, Seitenwänden und Stirnwänden (Packungswände), wobei eine durch zwei Perforationslinien in einer Packungswand begrenzte Aufreißlasche aufreißbar ist und wobei ein Klebestreifen vorgesehen ist, der einerseits mit der Aufreißlasche der Weichpackung und andererseits lösbar mit einer Packungswand verbunden ist.The invention relates to a soft pack made of a plastic film for cellulose products, in particular for holding paper handkerchiefs, with an essentially cuboid structure to form the front wall, rear wall, side walls and end walls (pack walls), a tear-open tab delimited by two perforation lines in a pack wall being able to be torn open and an adhesive strip is provided which is connected on the one hand to the tear-open tab of the soft pack and on the other hand detachably to a pack wall.

Eine derartige Packung ist bekannt aus der FR-A-23 34 584. Gemäß einer Ausführungsform dieser bekannten Weichpackung für Papiertaschentücher ist eine Entnahmeöffnung im Bereich einer Längs-Seitenwand gebildet. Zwei im Bereich dieser Seitenwand einander überdeckende Zuschnittlappen bilden zugleich in einem Teilbereich Verschlußlappen der Entnahmeöffnung. Zu diesem Zweck sind die Zuschnittlappen mit Abstand von den Enden der Seitenwandung mit quergerichteten Trennschnitten versehen, durch die das Auffalten der Verschlußlappen ermöglicht wird. Der äußere Verschlußlappen ist bei geschlossener Weichpackung durch einen Klebestreifen über Eck an der Vorderwand der Weichpackung befestigt.Such a pack is known from FR-A-23 34 584. According to one embodiment of this known soft pack for paper handkerchiefs, a removal opening is formed in the region of a longitudinal side wall. Two blanking tabs covering one another in the area of this side wall simultaneously form closing tabs of the removal opening in a partial area. For this purpose, the blanking tabs are provided with transverse separating cuts at a distance from the ends of the side wall, by means of which the closing tabs can be unfolded. When the soft pack is closed, the outer sealing flap is attached to the front wall of the soft pack by an adhesive strip over a corner.

Bei einer anderen Ausführungsform dieser bekannten Weichpackung ist eine also Verschluß der Entnahmeöffnung dienende Klapplasche vorgesehen, die durch Trennen von Seitlichen, parallel zueinander verlaufenden Perforationslinien im Bereich der Vorderwand und der angrenzenden Seitenwand gebildet wird. Nach dem Lostrennen dieser Klapplasche erstreckt sich diese über einen Teilbereich der Vorderwand sowie über die volle Breite (Querabmessung) der als Entnahmeöffnung dienenden Längs-Seitenwand. Im Bereich der Vorderwand ist in Schließstellung eine Teil- überdeckung mit derselben gegeben. Ein Klebestreifen ermöglicht die lösbare Befestigung der Klapplasche an der Vorderwand der Packung.In another embodiment of this known soft pack, a flap which serves to close the removal opening is provided and is formed by separating lateral, parallel perforation lines in the region of the front wall and the adjacent side wall. After this folding tab has been separated, it extends over a partial area of the front wall and over the full width (transverse dimension) of the longitudinal side wall serving as a removal opening. In the closed position there is partial overlap with the same in the area of the front wall. An adhesive strip enables the hinged flap to be detachably attached to the front wall of the pack.

Beiden vorstehenden Weichpackungen ist gemeinsam, daß die Entnahme der Papiertaschentücher im Bereich einer Längs-Seitenwand erfolgen muß. Diese Packungskonstruktion verfangt eine bestimmte Faltung der Papiertaschentücher, nämlich derart, daß der Entnahmeöffnung jeweils ein Falz zugekehrt ist. Die Bildung der Falze auf der der Entnahmeöffnung zugekehrten Seite der Papiertaschentücher erfordert einen bestimmten, aufwendigen Faitvorgang, der für die Hochleistungsmaschinen ungüngstig ist. Des weiteren sind Packungen mit einer Entnahmeöffnung im Bereich der langen Seitenwand weniger formstabil, wenn, wie in der Praxis üblich, die Querperforationen zur Begrenzung der Verschlußlaschen bzw. der Lapplasche mit größerem Abstand von den Enden der Seitenwand angebracht werden, ergibt sich eine Entnahmeöffnung, die deutlich kürzer ist als die Längsabmessung der zu entnehmenden Papiertaschentücher.Both of the above soft packs have in common that the paper handkerchiefs must be removed in the region of a longitudinal side wall. This pack construction entails a certain folding of the paper handkerchiefs, namely in such a way that a fold is turned towards the removal opening. The formation of the folds on the side of the paper handkerchiefs facing the removal opening requires a specific, complex folding process, which is inconvenient for the high-performance machines. Furthermore, packs with a removal opening in the region of the long side wall are less dimensionally stable, if, as is customary in practice, the transverse perforations for limiting the closure flaps or the flap flap are made at a greater distance from the ends of the side wall, a removal opening results is significantly shorter than the longitudinal dimension of the paper tissues to be removed.

Durch die US-A-25 29 583 ist ein KartonBehälter zur Aufnahme von Zellstofftüchern bekannt, bei der eine Entnahmeöffnung im Bereich einer Vorder- bzw. Oberwand und einer angrenzenden Stirnwand gebildet ist. Zu diesem Zweck wird ein durch Perforationen und Rundstanzungen markierter Lappen im Bereich der Vorderwand und Stirnwand markiert. Mit Hilfe einer kreisbogenförmigen, gestanzten Zunge im Bereich der Vorderwand kann die Lasche aus der ursprünglich geschlossenen Packung herausgetrennt werden, so daß die Entnahmeöffnung gebildet ist. Diese hat eine geringere Querabmessung als die Breite der Vorderwand bzw. die Länge der Stirnwand. Die entsprechenden Abmessungen sind dadurch kleiner als die Querabmessungen der zu entnehmenden, gefalteten Zellstofftücher. Die Perforationslinien laufen parallel zu den Begrenzungen der zugeordneten Wandungen der Packung. Ein Wiederverschließen der Packung ist nicht vorgesehen.From US-A-25 29 583 a cardboard container for receiving cellulose wipes is known, in which a removal opening is formed in the area of a front or top wall and an adjacent end wall. For this purpose, a flap marked by perforations and round punchings is marked in the area of the front wall and front wall. With the help of an arcuate, punched tongue in the area of the front wall, the tab can be separated from the originally closed package, so that the removal opening is formed. This has a smaller transverse dimension than the width of the front wall or the length of the front wall. The corresponding dimensions are therefore smaller than the transverse dimensions of the folded cellulose towels to be removed. The perforation lines run parallel to the boundaries of the associated walls of the pack. The package is not intended to be closed again.

Für die Aufnahme von Zellstofftüchern ist weiterhin eine aus Karton bestehende Packung durch die US-A-30 12 692 bekannt. Bei dieser Ausführung ist eine Entnahmeöffnung durch heraustrennen eines entsprechenden Lappens im Bereich einer Vorderwand sowie einer angrenzenden Seitenwand gebildet. Seitliche Perforationslinien zur Begrenzung der Lasche laufen konvergierend. Zum Heraustrennen der Lasche ist eine Zunge mit bogenförmiger Stanzung in Fortsetzung der Perforation im Bereich der Oberwand gebildet. Auch hier ist die Entnahmeöffnung von deutlich geringerer Breite als die entsprechenden Abmessungen der Zellstofftücher in der Packung. Ein Wiederverschluß dieser Karton-Packung ist nicht vorgesehen.A package made of cardboard is also known from US-A-30 12 692 for accommodating cellulose wipes. In this embodiment, a removal opening is formed by cutting out a corresponding tab in the area of a front wall and an adjacent side wall. Perforation lines on the side to delimit the tab converge. To remove the tab, a tongue is formed with an arcuate stamping, continuing the perforation in the area of the upper wall. Here, too, the removal opening is of significantly smaller width than the corresponding dimensions of the cellulose wipes in the package. A reclosure of this carton pack is not provided.

Bei einer bekannten Zigaretten-Packung (US-A-19 15 503) ist im Bereich einer (oberen) Stirnwand eine Entnahmeöffnung für die Zigaretten definiert. Diese wird durch Stanzungen bzw. Perforationslinien in einem seitlichen Bereich der Stirnfläche gebildet. Ein klebender Dichtungsstreifen überdeckt die Stirnwand im Bereich der Stanzungen bzw. Perforationslinien auf voller Breite und erstreckt sich mit einer entsprechenden Verlängerung in den Bereich der angrenzenden Seitenwand. Am freien Ende des Dichtungsstreifens ist ein haftfreier, schmaler Griffstreifen gebildet, der ein Erfassen und Hochziehen des Dichtungsstreifens ermöglicht. Durch die vollflächige Verbindung desselben mit einer durch die Stanzungen bzw. Perforationen definierten Öffnungslasche wird diese mit dem Dichtungsstreifen zur Bildung einer Entnahmeöffnung angehoben Der Dichtungsstreifen hat größere Querund Längsabmessungen als die Öffnungslasche, überragt diese somit allseitig.In a known cigarette pack (US-A-19 15 503), a removal opening for the cigarettes is defined in the region of an (upper) end wall. This is formed by punching or perforation lines in a lateral area of the end face. An adhesive sealing strip covers the front wall in the area of the punched areas or perforation lines over the full width and extends with a corresponding extension into the area of the adjacent side wall. At the free end of the sealing strip, a non-stick, narrow grip strip is formed, which enables the sealing strip to be gripped and pulled up. Due to the full-surface connection of the same with an opening tab defined by the punchings or perforations, the latter is raised with the sealing strip to form a removal opening. The sealing strip has larger transverse and longitudinal dimensions than the opening tab, and thus projects beyond it on all sides.

Eine derartige aus Karton bestehende Packung ist für die Aufnahme von Papiertaschentüchern aufgrund der Anordnung und Abmessung der Entnahmeöffnung nicht geeignet.Such a pack made of cardboard is not suitable for holding paper handkerchiefs due to the arrangement and dimensions of the removal opening.

Bei Weichpackungen für Papiertaschentücher ist es schließlich bekannt, außermittig eine ringsherumlaufende bzw. sich lediglich im Bereich der Vorderwand und angrenzender Seitenwände erstreckende Perforationslinie in der Kunststoffolie anzuordnen, so daß eine Öffnungskappe ganz oder teilweise von der Weichpackung abgetrennt werden kann. Soweit die Öffnungskappe mit einer Rückwand in Verbindung bleibt, ist dadurch ein nach Entnahme von Papiertaschentüchern wieder herstellbarer Verschluß der Weichpackung nicht möglich. Diese bekannten Weichpackungen sind nicht mit einem Klebestreifen ausgestattet.In the case of soft packs for paper handkerchiefs, it is finally known to arrange a perforation line running around the center or extending only in the area of the front wall and adjacent side walls in the plastic film, so that an opening cap can be completely or partially separated from the soft pack. Insofar as the opening cap remains connected to a rear wall, this means that it is not possible to re-seal the soft pack after removing paper tissues. These known soft packs are not equipped with an adhesive strip.

Der Erfindung liegt die Aufgabe zugrunde, bei einer eingangs erläuterten Weichpackung die Aufreißlasche in Verbindung mit dem Klebestreifen so anzuordnen und auszubilden, daß ein zuverlässiges Öffnen der Weichpackung, eine bequeme, störungsfreie Entnahme der Papiertaschentücher und eine weitgehende Formstabilität der Weichpackung trotz Verwendung äußerst dünnwandiger Kunststoffolien gewährleistet ist.The invention has for its object to arrange and develop the tear tab in connection with the adhesive strip in a soft pack explained at the outset such that reliable opening of the soft pack, convenient, trouble-free removal of the paper tissues and extensive dimensional stability of the soft pack despite using extremely thin-walled plastic films are ensured is.

Zur Lösung dieser Aufgabe ist die er-. findungsgemäße Weichpackung gekennzeichnet durch folgende Merkmale:

  • a) die Aufreißlasche ist als Teil der Vorderwand ausgebildet,
  • b) die Perforationslinien erstrecken sich von einem Laschenende der Aufreißlasche aus divergierend zu zwei an der Vorderwand mit der angrenzenden (oberen) Stirnwand gebildeten Ecken,
  • c) zwei Anschlußperforationen setzen den Verlauf der Perforationslinien von den Ecken aus in einem an die Vorderwand angrenzenden Teilbereich der Stirnwand fort,
  • d) die anschtußperforationen sind entlang seitlichen Faltkanten eines trapezförmigen äußeren Stirnlappens angeordnet,
  • e) die Perforationslinien sind am Laschenende durch einen quergerichteten, ununterbrochenen, geradlinigen Trennschnitt miteinander verbunden, an den sich die Perforationslinien unter einem Winkel anschließen,
  • f) der Trennschnitt ist bei geschlossener Weichpackung durch einen Klebestreifen überdeckt, dessen Breite, der Länge des Trennschnitts entspricht,
  • g) der Klebestreifen weist an seinem mit der Vorderwand verbundenen Ende eine haftfreie Grifflasche auf.
To solve this task, the. Soft pack according to the invention characterized by the following features:
  • a) the pull tab is formed as part of the front wall,
  • b) the perforation lines extend from one tab end of the tear-open tab to two corners formed on the front wall with the adjacent (upper) end wall,
  • c) two connecting perforations continue the course of the perforation lines from the corners in a partial area of the front wall adjoining the front wall,
  • d) the connection perforations are arranged along lateral folded edges of a trapezoidal outer front flap,
  • e) the perforation lines are connected to one another at the tab end by a transverse, uninterrupted, straight-line separating cut, to which the perforation lines are connected at an angle,
  • f) when the soft pack is closed, the separating cut is covered by an adhesive strip the width of which corresponds to the length of the separating cut,
  • g) the adhesive strip has at its end connected to the front wall an adhesive grip tab.

Bei der erfindungsgemäßen Weichpackung ist demnach die Aufreißlasche Bestandteil der Vorderwand, aus der sie beim Öffnen herausgetrennt wird. Dieser Vorgang erfolgt allein durch Betätigen des Klebestreifens, der die Aufreißlasche von dem Laschenende her erfaßt. Durch den quergerichteten, geradlinigen Trennschnitt ist gewährleistet, daß die Vorderwand der Verpackung vor Ingebrauchnahme keine wölbenden Verformungen der Kunststoffolie aufweist. Die an den Trennschnitt unter einem Winkel anschließenden, nämlich zu den Ecken der Vorderwand verlaufenden Perforationslinien sorgen in Verbindung mit dem quergerichteten Trennschnitt und dem in der Breite hierauf abgestimmten Klebestreifen für ein fehlerfreies Heraustrennen der Aufreißlasche aus der Vorderwand.In the soft packaging according to the invention, the tear-open tab is therefore part of the front wall, from which it is separated when it is opened. This process takes place solely by actuating the adhesive strip, which grips the tear-open tab from the end of the tab. The transverse, straight-line separating cut ensures that the front wall of the packaging has no bulging deformations in the plastic film before use. The perforation lines adjoining the separating cut at an angle, namely to the corners of the front wall, in conjunction with the transverse cutting cut and the adhesive strips which are matched to the width thereof, ensure that the tear-open tab is removed correctly from the front wall.

Die Aufreißlasche findet eine Fortsetzung im Bereich der angrenzenden Stirnwand, und zwar durch die verhältnismäßig kurzen, sich in einem Teilbereich der Stirnwand erstreckenden Anschlußperforationen. Durch diese ist die Entnahme der Papiertaschentücher erleichtert.The tear-open tab is continued in the area of the adjacent end wall, namely through the relatively short connection perforations extending in a partial area of the end wall. This makes it easier to remove the tissue.

Weitere Merkmale der erfindungsgemäßen Weichpackung sind Gegenstand der abhängigensprüche.Further features of the soft pack according to the invention are the subject of the dependent claims.

Embodiments of the invention are explained below with reference to the drawings. Show it:
  • 1 is a perspective view of a first embodiment of a (cuboid) package made of a plastic film for holding paper handkerchiefs,
  • 2, a spread blank from a plastic film for producing a pack with the features of the embodiment of FIG. 1,
  • Fig. 3 shows an embodiment of the soft pack with a concave tear tab in a perspective view.

In den Zeichnungen werden Ausführungsbeispiele für Weichpackungen wiedergegeben, die hier beispielshaft zur Aufnahme von Papiertaschentüchern 10 dienen. Ganz entsprechend können Packungen für die Annahme anderer Zellstoffartikel, zum Beispiel Damenbinden, Servietten etc., gestaltet sein.The drawings show exemplary embodiments for soft packs, which are used here, for example, to hold paper tissues 10. Packs for accepting other cellulose articles, for example sanitary napkins, napkins, etc., can be designed entirely accordingly.

Die im wesentlichen quaderförmigen Packungen bestehen hier aus einem einstückigen, rechteckigen Zuschnitt 11 (Fig. 2) aus einer schweißbaren oder klebbaren Kunststoffolie, zum Beispiel Polyäthylen. Der Zuschnitt 11 wird zunächst schlauchförmig um den Packungsinhalt herumgelegt. An den Enden überstehende Stirnlappen 12 und 13 bzw. 14 werden sodann gegen den Packungsinhalt umgefaltet. Die einzelnen durch entsprechende Linien in Fig. 2 markierten Felder des Zuschnitts 11 bilden dadurch eine Vorderwand 15, eine Rückwand 16, demgegenüber schmalere Seitenwände 17 und 18, sowie Stirnwände 19 und 20.The essentially cuboid packs here consist of a one-piece, rectangular blank 11 (FIG. 2) made of a weldable or adhesive plastic film, for example polyethylene. The blank 11 is first placed around the contents of the package in a tube. End flaps 12 and 13 and 14 protruding at the ends are then folded over against the contents of the pack. The individual fields of the blank 11 marked by corresponding lines in FIG. 2 thereby form a front wall 15, a rear wall 16, on the other hand narrower side walls 17 and 18, and end walls 19 and 20.

Die letzgenannten Stirnwände 19, 20 werden durch die entsprechend gefalteten Stirnlappern 12, 13, 14 gebildet, von denen der der Vorderwand 15 zugeordnete (äußere) Stirnlappen 12 ebenso wie der entsprechende, an die Rückwand 16 anschließende Stirnlappen 13 eine trapezförmige Gestalt durch den Faltvorgang erhalten. Die Stirnlappen 12, 13, 14 sind durch thermische Schweißung, gegebenenfalls aber auch durch Klebung miteinander verbunden.The latter end walls 19, 20 are formed by the correspondingly folded end flaps 12, 13, 14, of which the (outer) end flap 12 assigned to the front wall 15 and the corresponding end flap 13 adjoining the rear wall 16 are given a trapezoidal shape by the folding process . The front flaps 12, 13, 14 are connected to one another by thermal welding, but possibly also by gluing.

Seitenstreifen 21 und 22 des Zuschnitts 11 1 bilden im Bereich der Seitenwand 17 eine hier im einzelnen nicht gezeigte Überlappung. Die Seitenstreifen 21, 22 sind dabei ebenfalls durch thermische Schweißung miteinander verbunden.Side strips 21 and 22 of the blank 11 1 form an overlap (not shown here in detail) in the region of the side wall 17. The side strips 21, 22 are also connected to one another by thermal welding.

Die vorgenannten Packungswände 15, 20 sind durch Kanten gegeneinander abgegrenzt, im Bereich der Vorderwand 15 durch die Längskanten 23 und 24 sowie gegenüber der Stirnwand 19 durch eine Querkante 25.The aforementioned packing walls 15, 20 are delimited from one another by edges, in the region of the front wall 15 by the longitudinal edges 23 and 24 and opposite the end wall 19 by a transverse edge 25.

Die Packungen werden durch Aufreißen geöffnet, können aber nach Entnahme eines Teilinhalts wieder verschlossen werden.The packages are opened by tearing them open, but can be closed again after removing some of the contents.

Bei dem hier gezeigten bevorzugten Ausführungsbeispiel ist die rechteckige Vorderwand 15 im oberen, der Stirnwand 19 zugekehrten Bereich mit einer sich über die gesamte Breite der Vorderwand 15 erstreckenden Aufreißlasche 26 versehen. Diese hat demnach im breitesten Bereich die Querabmessung entsprechend der kleineren (quergerichteten) Abmessung der Vorderwand.In the preferred exemplary embodiment shown here, the rectangular front wall 15 is provided in the upper area facing the end wall 19 with a tear-open tab 26 which extends over the entire width of the front wall 15. In the broadest area, this has the transverse dimension corresponding to the smaller (transverse) dimension of the front wall.

Die Aufreißlasche 26 ist durch Reißlinien markiert und begrenzt, die aufgrund einer Materialschwächung der Kunststoffolie den Aufreißvorgang ermöglichen. Bei den vorliegenden Ausführungsbeispielen wird die Aufreißlasche 26 durch Perforationslinien 29, 30 begrenzt, die im weitesten Sinne in Aufreißrichtung, also in Richtung zur Stirnwand 19 weisen, jedenfalls unter einem Winkel zueinander laufen, der kleiner ist also 18O°.The tear-open tab 26 is marked and delimited by tear lines which enable the tear-open process due to a weakening of the plastic film. In the present exemplary embodiments, the tear-open tab 26 is delimited by perforation lines 29, 30, which in the broadest sense point in the tear-open direction, that is to say in the direction of the end wall 19, at least at an angle to one another which is smaller than 180 °.

Bei dem Ausführungsbeispiel gemäß Fig. 1 erhält die Aufreißlasche 26 eine im wesentlichen trapezförmige Gestalt, durch zwei jeweils zu den Ecken 27 und 28 der Vorderwand 15 laufende Perforationslinien 29 und 30. Ein etwa mittig zur Vorderwand 15 liegendes Laschenende 31 wird hier durch einen die zugekehrten Enden der Perforationslinien 29, 30 miteinander verbindenden, ununterbrochenen Trennschnitt 32 markiert. Dieser erleichtert den kritischen Anfang des Aufreißvorgangs durch Erfassen und Hochziehen des Laschenendes 31.In the embodiment according to FIG. 1, the tear-open tab 26 has an essentially trapezoidal shape, through two perforation lines 29 and 30 running to the corners 27 and 28 of the front wall 15, respectively. A tab end 31 lying approximately centrally to the front wall 15 is here the one facing Marked ends of the perforation lines 29, 30 connecting, continuous separation cut 32. This facilitates the critical start of the tearing process by grasping and pulling up the tab end 31.

Um eine die Entnahme des Packungsinhalts erleichternde Öffnung durch die Aufreißlasche 26 zu schaffen, werden die Perforationslinien 29, 30 durch anschlußperforationen 33 und 34 im Bereich der Stirnwand 19 fortgesetzt, und zwar am Rand bzw. innerhalb einer seitlichen Faltkante 35 des äußeren Stirnlappens 12. Die Anschlußperforationen 33, 34 können auch als durchgehender Trennschnitt ausgeführt sein.In order to create an opening through the tear tab 26 which facilitates the removal of the package contents, the perforation lines 29, 30 are continued by connection perforations 33 and 34 in the region of the end wall 19, namely on the edge or within a lateral folded edge 35 of the outer end flap 12 Connection perforations 33, 34 can also be designed as a continuous separating cut.

Das sich bei diesen Ausführungsbeispiel ergebende Bild der Perforationslinien 29, 30 einschließlich Trennschnitte 32 ist in Fig. 2 erkennbar. Die einfache geometrische Gestalt ist sehr einfach durch entsprechende Trennmesser herstellbar.The resulting image of the perforation lines 29, 30 including separating cuts 32 in this exemplary embodiment can be seen in FIG. 2. The simple geometric shape can be produced very easily by means of appropriate cutting knives.

Bei dem Ausführungsbeispiel gemäß Fig. 3 ist das Laschenende 31 der Aufreißlaschen 26 besonders betont, da durch eine konkave Gestaltung der Perforationslinien 29 und 30 das Laschende 31 zungenartig ausgebildet ist. Ein quergerichteter Trennschnitt 32 schließt auch hier an die Enden der Perforationslinien 29, 30 an. Die Perforationslinien 29, 30 führen hier in die Ecken 27 und 28 der Packung.In the embodiment according to FIG. 3, the tab end 31 of the tear tabs 26 is particularly emphasized, since the tab end 31 is tongue-shaped due to a concave design of the perforation lines 29 and 30. A transverse cut 32 also adjoins the ends of the perforation lines 29, 30 here. The perforation lines 29, 30 lead here into the corners 27 and 28 of the pack.

Bei allen Ausführungsbeispielen ist den Aufreißlaschen 26 jeweils ein Verschlußorgan in Gestalt eines Klebestreifens 40 zugeordnet. Dieses ist mit einem (längeren) Haftabschnitt 41 durch Klebung mit der Aufreißlasche 26 verbunden. Der daran anschließende Abziehteil 42 ist mit erheblich kleinerer Haftfläche ausgebildet und durch Klebung lösbar mit dem anschließenden Teil der Vorderwand 15 verbunden. Eine am Ende des Klebestreifens 40 gebildete nichthaftende Grifflasche 43 ermöglicht das Erfassen und Abziehen des Klebestreifens 40. Dabei wird bei geschlossener Packung zunächst der Abziehteil 42 von der Vorderwand 15 gelöst. Bei weiterer Abziehbewegung des Klebestreifens 40 wird die Aufreißlasche 26 entlang den Perforationslinien 29, 30 etc. von der Vorderwand 15 gelöst, da der Klebestreifen 40 infolge entsprechender Haftung mit der Aufreißlasche 26 in Verbindung bleibt. Durch diesen Aufreißvorgang wird eine den beschriebenen Perforationslinien, Anschlußperforationen etc. entsprechende Öffnung freigelegt, die die Entnahme des Packungsinhalts ermöglicht. Nach einer Teilentnahme kann die Packung wieder verschlossen werden, und zwar mit Hilfe des Klebestreifens 40. Ein mehrfacher Öffnungs-und Schließvorgang ist durchführbar.In all of the exemplary embodiments, the pull tabs 26 are each assigned a closure member in the form of an adhesive strip 40. This is connected to a (longer) adhesive section 41 by gluing to the tear tab 26. The subsequent pull-off part 42 is designed with a considerably smaller adhesive surface and is detachably connected to the adjoining part of the front wall 15 by adhesive. A non-adhesive grip tab 43 formed at the end of the adhesive strip 40 enables the adhesive strip 40 to be gripped and pulled off. In this case, when the package is closed, the pull-off part 42 is first detached from the front wall 15. When the adhesive strip 40 is pulled off further, the tear-open tab 26 is detached from the front wall 15 along the perforation lines 29, 30 etc., since the adhesive strip 40 remains connected to the tear-open tab 26 as a result of appropriate adhesion. This tear-open process exposes an opening corresponding to the described perforation lines, connection perforations, etc., which enables the contents of the package to be removed. After a partial removal, the package can be closed again, with the aid of the adhesive strip 40. A multiple opening and closing process can be carried out.

Der Klebestreifen 40 ist im vorliegenden Fall so angeordnet, daß im Bereich des Laschenendes 31 der Trennschnitt 32 überdeckt ist. Die Breite des Klebestreifens 40 entspricht deshalb hier etwa der Länge des Trennschnitts 32. Alternativ kann aber der Trennschnitt zur besseren Markierung des Laschenendes 31 teilweise bis in den Bereich der Perforationslinien 29, 30 geführt werden. Dabei ist es zweckmäßig, den Klebestreifen 40 entsprechend breiter auszubilden, so daß auch bei dieser Alternative der Trennschnitt 32 überdeckt ist.In the present case, the adhesive strip 40 is arranged such that the separating cut 32 is covered in the area of the tab end 31. The width of the adhesive strip 40 therefore corresponds approximately to the length of the separating cut 32 here. Alternatively, the separating cut can, in some cases, be made up to the area of the perforation lines 29, 30 for better marking of the tab end 31. It is expedient to make the adhesive strip 40 correspondingly wider, so that the separating cut 32 is also covered in this alternative.

Die gefalteten Papiertaschentücher 10 sind zweckmäßigerweise so angeordnet, daß ein Endfalz 44, der durch die Aufreißlasche 26 gebildeten Öffnung der Packung zugekehrt ist, so daß das Erfassen der Papiertaschentücher 10 zur Entnahme erleichtert ist.The folded paper handkerchiefs 10 are expediently arranged such that an end fold 44, which faces the opening of the pack formed by the tear-open tab 26, so that the gripping of the paper handkerchiefs 10 for removal is facilitated.
