Abstract

Un emballage refermable pour torchons humides, dans lequel une ligne de déchirage est tracée sur la surface supérieure essentiellement plate, et qui est recouvert d'un rabat de fermeture présentant un profil plus grand et qui colle au matériau de la surface supérieure. Un tel emballage doit être amélioré de telle façon que la bande de matériau découpée recouvre l'ouverture d'extraction avec autant de précision que possible lorsque l'emballage est refermé. A cette fin, la ligne de perforation pour le déchirage ou ligne poinçonnée n'est pas entièrement découpée mais forme une languette de recouvrement d'une seule pièce reliée à la surface supérieure. Les côtés poinçonnées (10, 11), qui forment la languette de recouvrement (9), se prolongent largement jusqu'à un cordon de soudure avec lequel le rabat de fermeture est relié à la surface supérieure de l'emballage.A resealable package for wet cloths, in which a tear line is drawn on the substantially flat upper surface, and which is covered with a closing flap having a larger profile and which sticks to the material of the upper surface. Such packaging must be improved so that the strip of cut material covers the extraction opening with as much precision as possible when the packaging is closed. To this end, the perforation line for tearing or punched line is not entirely cut but forms a covering tab in one piece connected to the upper surface. The punched sides (10, 11), which form the cover tab (9), extend widely to a weld bead with which the closure flap is connected to the upper surface of the package.

Description

Verpackung packaging
Die Erfindung betrifft eine wiederverschliessbare Verpackung für feuchte Tücher oder dergleichen gemäss dem Oberbegriff. Eine solche Verpackung ist aus DE-OS 28 00 165 sowie aus EP 30 348 bekannt. Diese Verpackungen sind aus Plastikfolie zu- sammengeschweisst und somit dampfdicht. Die Verpackung soll nach jedesmaliger Entnahme eines feuchten Tuches wieder dampfdicht verschliessbar sein. Hierzu dient die mit einem Haftkleber be¬ schichtete Verschlussklappe. Der Haftkleber soll aber nicht an dem jeweils oberen Tuch anhaften. Zu diesem Zweck ist der zur Bildung der Entnahmeöffnung aus der Oberseite der Verpackung aus¬ gestanzte Materialstreifen nicht entfernt; beim Hochziehen der Verschlussklappe bleibt dieser Materialstreifen somit an diesem haften; beim erneuten Verschliessen deckt der ausgestanzte Ma- terialstreifen die Öffnung wiederum ab. Diese Abdeckung kommt auch der Dichtheit zugute. Bei der üblichen Handhabung kommt aber der ausgestanzte Materialstreifen nicht genau über die längsge¬ streckte Entnahmeöffnung zu liegen, sondern nach der einen oder der anderen Seite versetzt, es bleibt somit ein meist spitzwink¬ liger Schlitz, der von dem ausgestanzten Materialstreifen nicht abgedeckt ist. Der Verschluss ist dann nicht mehr völlig dicht und die Verschlussklappe kann an dem Inhalt der Packung, insbe¬ sondere an dem obersten Tuch, haften.The invention relates to a reclosable packaging for wet wipes or the like according to the preamble. Such packaging is known from DE-OS 28 00 165 and from EP 30 348. This packaging is welded together from plastic film and is therefore vapor-tight. The packaging should be able to be closed again vapor-tight after each removal of a damp cloth. The closure flap coated with a pressure sensitive adhesive serves for this purpose. The pressure sensitive adhesive should not adhere to the top cloth. For this purpose, the material strip punched out of the top of the packaging to form the removal opening has not been removed; when the flap is pulled up, this strip of material sticks to it; when it is closed again, the punched-out material strip the opening again. This cover also benefits the tightness. In normal handling, however, the punched-out material strip does not come to lie exactly over the elongated removal opening, but rather is offset on one or the other side, so that there remains a mostly acute-angled slot which is not covered by the punched-out material strip. The closure is then no longer completely tight and the closure flap can adhere to the contents of the package, in particular to the top cloth.
Der Erfindung liegt die Aufgabe zugrunde, zur möglichst vollstän¬ digen Beseitigung dieser Nachteile diese Packung so ohne zusätz¬ lichen Aufwand auszubilden, dass der gestanzte Materialstreifen beim Wiederverschliessen die Entnahmeöffnung genau abdeckt. Zur Lösung dieser Aufgabe ist der zur Bildung der Öffnung ge¬ stanzte Teil nicht völlig ausgestanzt, sondern die eine Seite der Entnahmeöffnung, welche das Gelenk zwischen Verschlussklappe und Packungsoberseite bilden, ist nicht gestanzt, an dieser Seite bleibt der Materialstreifen einstückig mit der Packungsoberseite im übrigen. Durch diese Einstückigkeit kommt der Materialstreifen beim Verschliessen weit besser mit der Entnahmeöffnung zur Deckung. Beim Öffnen der Packung besteht aber die Gefahr, dass der Materi¬ alstreifen längs den beiden Enden der Stanzlinie weiter aufge¬ rissen wird. Um auch dies zu vermeiden, erstrecken sich die Stanzlinien von vorneherein bis zu einer an sich üblichen Schweissnaht zwischen Verschlussklappe und Packungsoberseite bzw. ist die Schweissnaht bis an die Enden der Stanzlinien, d.h. bis an die eine Schmalseite der Öffnung vorversetzt. Die Enden oder "Wurzeln" der Stanzschnitte werden also sozusagen mit der Schweissnaht verankert und somit wird einem Weiterreissen ent¬ gegengewirkt. Zur weiteren Verbesserung enden die Stanzlinien nicht geradlinig, sondern in je einem nach aussen gerichteten Bogen. Auf diese Weise ist die das Weiterreissen begünstigende "Kerbwirkung" vermieden. Ferner kann die Schweissnaht zwischen Verschlussklappe und Packungsoberseite konkav oder gestuft verlaufen. Auf diese Weise sind die Enden der Stanzlinien vom Zug entlastet und der Zug verteilt sich über die ganze Breite der Öffnung und über diese hinaus über die gesamte Breite der Verschlussklappe.The object of the invention is to develop these packs without additional effort in order to eliminate these disadvantages as completely as possible in such a way that the punched strip of material exactly covers the removal opening when it is reclosed. To achieve this object, the part punched to form the opening is not completely punched out, but the one side of the removal opening, which forms the joint between the closure flap and the top of the pack, is not punched; on this side, the material strip remains integral with the top of the pack . Due to this one-piece design, the material strip comes into better alignment with the removal opening when it is closed. When the package is opened, however, there is a risk that the strip of material will be torn open further along the two ends of the punching line. In order to avoid this, too, the punched lines extend from the outset to a conventional weld seam between the closure flap and the top of the pack, or the weld seam is offset up to the ends of the punched lines, ie to one narrow side of the opening. The ends or "roots" of the die cuts are anchored, so to speak, to the weld seam and thus counteracting further tearing. For further improvement, the punching lines do not end in a straight line, but in an outward curve. In this way, the "notch effect" favoring the tearing is avoided. Furthermore, the weld seam between the closure flap and the top of the pack can be concave or stepped. In this way, the ends of the punching lines are relieved of the tension and the tension is distributed over the entire width of the opening and beyond this over the entire width of the closure flap.

Nachfolgend werden Ausführungsbeispiele der Erfindung anhand der Zeichnung beschrieben.Exemplary embodiments of the invention are described below with reference to the drawing.
Fig. 1 zeigt perspektivisch eine erfindungsgemässe Verpackung, geschlossen.1 shows in perspective an inventive packaging, closed.
Fig. 2 zeigt die Verpackung gemäss Fig. 1, geöffnet, wobei die Verschlussklappe im Bereich ihrer Schweissnaht aufgebrochen bzw. entfernt ist.FIG. 2 shows the packaging according to FIG. 1, opened, the closure flap being broken open or removed in the area of its weld seam.
Fig. 3 - 7 zeigen in Draufsicht je eine (also insgesamt 5) verschiedene Ausführung der Erfindung.3 to 7 each show a top view of a different embodiment of the invention (ie a total of 5).
Fig. 8 und 9 zeigen eine weitere Variante in Draufsicht bzw. im Längsschnitt nach Linie IX-IX in Fig.8, Fig. 10 - 13 zeigen eine Ausführung, bei welcher am rückwärtigen Rand der Verschlussklappe keine Schweissnaht erforderlich ist.8 and 9 show a further variant in plan view or in longitudinal section along line IX-IX in Fig. 8, 10-13 show an embodiment in which no weld seam is required at the rear edge of the closure flap.
Die Packung besteht aus flexibler Kunststoffolie, vordere und hintere Schweissnähte sind mit 1, 2 bezeichnet. Die Verpackung enthält ein Päckchen feuchte Tücher. Auf der Oberseite 3 ist ein offenbarer Verschluss vorgesehen, durch den jeweils ein Tuch entnommen werden kann. Hierzu ist in an sich bekannter Weise in der Oberseite der Verpackung eine Entnahmeöffnung 4 vorgesehen, die mittels einer Verschlussklappe 5 geöffnet und wieder ver¬ schlossen werden kann. Die Verschlussklappe 5 ist mit einem Haftkleber 6 beschichtet und längs ihrer einen Schmalseite mittels einer Schweissnaht 7 auf der Oberseite 3 festgeschweisst; an der gegenüberliegenden Schmalseite ist eine mit Kleber nicht beschichtete Griffzunge 8 vorgesehen. Die Verschlussklappe 5 ist im Umriss grösser als die Entnahmeöffnung 4 und mittig zu der Entnahmeöffnung 4 angeordnet, so dass die Verschlussklappe 5 den Rand der Entnahmeöffnung 4 allseitig übergreift und somit ab¬ dichtet.The pack consists of flexible plastic film, front and rear weld seams are labeled 1, 2. The package contains a packet of wet wipes. An openable closure is provided on the top 3, through which a cloth can be removed in each case. For this purpose, in a manner known per se, a removal opening 4 is provided in the top of the packaging, which can be opened and closed again by means of a closure flap 5. The closure flap 5 is coated with a pressure sensitive adhesive 6 and welded along its one narrow side by means of a weld seam 7 on the upper side 3; on the opposite narrow side, a handle tongue 8 not coated with adhesive is provided. The closure flap 5 is larger in outline than the removal opening 4 and is arranged in the center of the removal opening 4, so that the closure flap 5 overlaps the edge of the removal opening 4 on all sides and thus seals.
Die Entnahmeöffnung 4 ist gestanzt. Der ausgestanzte Teil ist aber nicht entfernt, er kommt also beim Verschliessen der Ver- schlussklappe 5 wieder zur Anlage und deckt somit als Abdeckzun¬ ge 9 wiederum das oberste Tuch ab. Statt durchgehender Stanzli¬ nien können auch lediglich Perforationslinien in der Oberseite 1 vorgesehen sein, wobei aber der der Griffzunge 8 zugewandte Be¬ reich voll ausgestanzt ist, damit hier die Abdeckzunge 9 beim Öffnen an der Verschlussklappe 5 haften bleibt. Gemäss der Erfindung ist die Abdeckzunge 9 an ihrem der Griff¬ zunge 8 gegenüberliegenden Ende nicht gestanzt, sondern die Abdeckzunge 9 ist hier einstückig mit dem Material der Oberseite 3 im übrigen. Die Enden der Schenkel 10, 11 der Stanzung oder Perforation enden also "blind". Durch diese Einstückigkeit wird erreicht, dass beim Verschliessen die Abdeckzunge 9 genau über der Öffnung 4 zu liegen kommt, also die Öffnung 4 vollständig abdeckt. Da ferner die Schenkel 10, 11 der Stanzlinien an oder in der Schweissnaht 7 enden, erfolgt eine Versteifung oder Verstärkung, womit ein Weiterreissen beim Öffnen vermieden wird. Ausserdem oder zusätzlich können die Enden dieser Stanzschenkel 10, 11 in zur Seite nach aussen gerichtete Bögen 12, 13 aus¬ laufen, womit ein Weiterreissen aufgrund "Kerbwirkung" vermieden wird (Fig. 4, 5). Man kann diese Bögen 12,13 auch nach innen richten, sofern dann die Breite der Abdecklasche 9 in diesem Gelenk-Bereich nicht zu gering wird. Bei der Ausführung nach Fig„ 6 ist die Schweissnaht 7 "gestuft", d.h. es sind zwei gegenüber deπi mittleren Bereich vorversetzte seitliche Bereiche 7a, jeweils beidseits der Abdecklasche 9 vor¬ gesehen, jeweils auch voiversetzt gegenüber den Enden der Stanz¬ schenkel 10,11. Die Verschlnnssklappe 5 - und damit die an ihr haftende Abdecklasche 9 - lassen sich (ohne Zerstörung) nur bis an die vorversetzten Sεüweissnahtbereiche 7a abziehen; die Enden der Stanzschenkel 10,11 sind also von Zug völlig entlastet. Die gleiche Wirkungsweise, also Zugentlastung der Stanzschenkel¬ enden, wird auch bei der geschleiften Anordnung der Schweissnaht 7 gemäss Fig. 7 erreicht^ auch hier wird der Zug beim Aufziehen der Verschlussklappe 5 vorn, den vorversetzten seitlichen Bereichen 7b aufgefangen.The removal opening 4 is punched. However, the punched-out part is not removed, so it comes when the seal is closed. closing flap 5 back to the system and thus covers the top cloth again as covering tongue 9. Instead of continuous punch lines, only perforation lines can also be provided in the upper side 1, but the area facing the grip tongue 8 is fully punched out so that the cover tongue 9 adheres to the closure flap 5 when opened. According to the invention, the cover tongue 9 is not punched at its end opposite the handle tongue 8, but the cover tongue 9 is integral with the material of the upper side 3. The ends of the legs 10, 11 of the punching or perforation thus end "blindly". This one-piece arrangement ensures that when the cover tongue 9 is closed it lies exactly above the opening 4, that is to say it completely covers the opening 4. Furthermore, since the legs 10, 11 of the punching lines end at or in the weld seam 7, stiffening or reinforcement takes place, thereby preventing tearing when opening. In addition or in addition, the ends of these punch legs 10, 11 can run out into arches 12, 13 directed outward to the side, with the result that tearing due to the "notch effect" is avoided (FIGS. 4, 5). These arches 12, 13 can also be directed inward, provided that the width of the cover flap 9 does not become too small in this joint area. In the embodiment according to FIG. 6, the weld seam 7 is "stepped", ie there are two lateral regions 7a offset in relation to the central region, each provided on both sides of the cover flap 9, in each case also offset from the ends of the stamped legs 10, 11 . The closure flap 5 - and thus the cover flap 9 adhering to it - can only be pulled off (without destruction) up to the pre-offset areas of the weld seam 7a; the ends of the punch legs 10, 11 are thus completely relieved of train. The same mode of action, that is to say strain relief of the punch leg ends, is also achieved in the case of the looped arrangement of the weld seam 7 according to FIG. 7. Here too, the tension is caught when the closure flap 5 is pulled open at the front, the offset lateral regions 7b.
Statt der Schweissnähte 737a,7ib kann grundsätzlich auch eine Klebenaht bzw. ein Klebestτeifen vorgesehen sein, wobei die Klebeverbindung längs dieser Waht bedeutend fester als die Haftung an den Randbereichen 14 zwischen Vεxschlussklappe 5 und Oberseite 3 ist.Instead of the weld seams 7 3 7a, 7ib, an adhesive seam or an adhesive tape can in principle also be provided, the adhesive connection along this seam being significantly stronger than the adhesion to the edge regions 14 between the sealing flap 5 and the upper side 3.
Eine solche Ausführung zeigen Fig. 8 und 9» Die Klebenaht 7c zwischen Verschlussklappe 5 und Oberseite 3 ist dabei relativ breit. Die Stanzschenkel 10, 11 erstrecken sich bis in diese Klebenaht 7c hinein. Diese Klebenaht 7c bzw. der Klebestrei¬ fen ist von einem Klebstoff 6a mit bedeutend grosserer Klebekraft (permanenter Haftkleber) als der Haftkleber 6 (lösbarer Haftkle- ib.ex.) längs des übrigen Bereiches der Verschlussklappe 5 gebildet.Such an embodiment is shown in FIGS. 8 and 9. The adhesive seam 7c between the closure flap 5 and the upper side 3 is relatively wide. The punch legs 10, 11 extend into this Glue seam 7c. This adhesive seam 7c or the adhesive strip is formed by an adhesive 6a with a significantly greater adhesive force (permanent pressure-sensitive adhesive) than the pressure-sensitive adhesive 6 (detachable pressure-sensitive adhesive) along the remaining area of the closure flap 5.
Man kann die Verpackung gemäss Fig. 10 - 13 auch dahingehend vereinfachen, d.h. verbilligen, dass man die gesonderte Schweissnaht 7 oder Klebenaht 7c, zwischen Verschlussklappe 5 und Packungsoberseite 3 völlig fortlässt, sofern man nur die beiden Stanzschenkel 10,11 jeweils in einen Bogen 12,13 auslaufen lässt. Wenn nämlich beim erstmaligen und jedem weiteren Abziehen der Verschlussklappe 5 diese Bogen 12,13 erreicht werden, erhöht sich der Zug-Widerstand sprunghaft - womit beim praktischen Gebrauch der Vorgang des Öffnens beendet ist. The packaging according to FIGS. 10-13 can also be simplified, that is, cheaper, by completely omitting the separate weld seam 7 or adhesive seam 7c between the closure flap 5 and the top side 3 of the package, provided that only the two punch legs 10, 11 are each in an arc 12 , 13 can leak. If this arch 12, 13 is reached when the closure flap 5 is pulled off for the first time and each time it is pulled further, the tensile resistance increases by leaps and bounds - which ends the process of opening in practical use.
Eine solche Ausführung ist in Fig. 10, 11 gezeigt. Damit die Stanzschenkel 10,11 beim Aufziehen der Verschlussklappe 5 nicht weiterreissen, laufen die Stanzschenkel 10, 11 in seitliche Bögen 12, 13 aus. Diese Bögen können zur Seite nach aussen ge¬ richtet sein, wie bei Fig. 4, 5 oder aber auch nach innen ge¬ richtet, wie bei Fig. 12 und 13. Beim Aufziehen der Verschluss¬ klappe 5 wird der Zug über die Abdecklasche 9 und den Wurzelbe¬ reich oder Steg 15 zwischen den Stanzlinien 10, 11 auf die Packungsoberseite 3 übertragen, also der rückwärtige Bereich der Verschlussklappe 5 vom Zug völlig entlastet. Such an embodiment is shown in FIGS. 10, 11. So that the punch legs 10, 11 do not tear further when the closure flap 5 is opened, the punch legs 10, 11 run out into lateral arches 12, 13. These arches can be directed outwards to the side, as in FIGS. 4, 5, or can also be directed inwards, as in FIGS. 12 and 13. When the closure flap 5 is pulled, the pull over the cover flap 9 and transfer the root area or web 15 between the punching lines 10, 11 to the top side 3 of the pack, that is to say the rear area of the closure flap 5 is completely relieved of the tension.
