Abstract

In reclosable packages for moist cloths, consisting of a plastic film (3) with a punched-out portion on the upper side, in order to avoid loss of moisture in the region of the punched-out portion or corrosion when using composite aluminium foil, it is proposed to arrange a sheet (16, 17) which is impermeable to liquid between the flat upper side of the film and the moist cloths, covering the tear-open line or the punch cut (10, 11) and extending significantly beyond the edges of the punch cut. <IMAGE>

Description

Die Erfindung betrifft eine wiederverschließbare Verpackung für feuchte Tücher oder dergleichen gemäß dem Oberbegriff der Ansprüche 1 bzw. 2 und wie aus EP-A- 30 348 bekannt.The invention relates to a reclosable packaging for wet wipes or the like according to the preamble of claims 1 and 2 and as known from EP-A-30 348.

Eine ähnliche Verpackung ist aus der EP-A- 0 221 168 bekannt. Diese bekannte Verpackung besteht aus einer Kunstoff-Verbundfolie, die aufgrund ihrer Eigenschaften keine befriedigende Sperrschicht für Flüssigkeiten, mit denen die Tücher getränkt sind, bilden. Beispielsweise können in derartigen Verbundfolien keine Füllgüter mit hohen Parfumanteilen bzw. Alkohol (bis zu 40 %) verpackt werden.A similar packaging is known from EP-A-0 221 168. This known packaging consists of a plastic composite film which, due to its properties, does not form a satisfactory barrier layer for liquids with which the wipes are impregnated. For example, no filling goods with high perfume or alcohol (up to 40%) can be packed in such composite films.

Aus der EP-A- 0 030 348 ist eine wiederverschließbare Verpackung für feuchte Tücher oder dergleichen aus einer Aluminiumverbundfolie bekannt, auf deren Oberseite eine die Entnahmeöffnung überdeckende, mit einem Ende an der Oberseite unlösbar verbundene Verschlußklappe angeordnet ist, wobei zwischen der flachen Oberseite der Folie und den feuchten Tüchern ein flüssigkeitsundurchlässiges Blatt angeordnet ist, das die Aufreißlinie des Stanzschnittes abdeckt. Hierbei ist aber die durch die Stanzlinien geformte Abdeckzunge entfernt, und die Verschlußklappe ist klebend mit dem Blatt verbunden, wodurch das Blatt beim Öffnen der Abdecklasche aus der Entnahmeöffnung herausgezogen wird. Das Blatt erfüllt dabei in etwa die Funktion der aus der EP-PS 0 221 168 bekannten Abdeckzunge mit dem Unterschied, daß beim Wiederverschließen die Ränder der Entnahmeöffnung ein wenig überdeckt werden. Durch die relativ geringfügige Überlappung des Blattes bei der noch ungeöffneten Verpackung ist nicht auszuschließen, daß die Flüssigkeit den kurzen Weg zur Entnahmeöffnung überwindet. Bei den oben angesprochenen Aluminium-Verbundfolien treten somit die unerwünschten Korrosionserscheinungen auf.From EP-A-0 030 348 a reclosable packaging for wet wipes or the like is known from an aluminum composite film, on the upper side of which there is a closing flap covering the removal opening and having one end permanently connected to the upper side, between the flat upper side of the film and a liquid-impermeable sheet is arranged on the damp cloths and covers the tear line of the die cut. Here, however, the cover tongue formed by the punched lines is removed, and the closure flap is adhesively connected to the sheet, as a result of which the sheet is pulled out of the removal opening when the cover tab is opened. The sheet roughly fulfills the function of the cover tongue known from EP-PS 0 221 168 with the difference that the edges of the removal opening are covered a little when reclosing. Due to the relatively slight overlap of the sheet when the packaging is still unopened, it cannot be ruled out that the liquid will overcome the short distance to the removal opening. In the case of the aluminum composite films mentioned above, the undesirable corrosion phenomena occur.

Es ist jedoch bei der vorbekannten Verpackung nicht möglich, das Blatt beliebig zu vergrößern. Zum einem würde beim Öffnen der Packung die Schwierigkeit auftreten, daß der Ausschnitt nicht gänzlich aus der Verpackung herausgezogen wird, so daß beim Wiederverschließen Falten und Falzungen im Einlegeblatt entstehen, die einen dichten Wiederverschluß der Packung verhindern.However, with the previously known packaging it is not possible to enlarge the sheet as desired. On the one hand, when opening the package, the difficulty would arise that the cutout would not be completely pulled out of the package, so that folds and folds in the Insert sheets are created which prevent the pack from being sealed properly.

Zum anderen muß die Breite und Länge des Blattes in jedem Fall kleiner sein als die Breite und Länge der Verschlußklappe, da diese ansonsten nicht mehr auf der Packungsoberfläche haftet.On the other hand, the width and length of the sheet must in any case be smaller than the width and length of the closure flap, since this would otherwise no longer adhere to the surface of the package.

Somit sind dem Fachmann bei der Optimierung der vorbekannten Verpackung enge Grenzwerte zur Dimensionierung des Blattes gesetzt. Das bedeutet weiterhin, daß bei der Herstellung der Verpackung eine hohe Genauigkeit bei der Positionierung des Blattes eingehalten werden muß.The skilled person is thus set narrow limits for dimensioning the sheet when optimizing the known packaging. This also means that a high level of accuracy in the positioning of the sheet must be maintained in the manufacture of the packaging.

Es ist weiterhin aus der EP-A- 0 193 130 (Fig. 19 + 20 mit Beschreibungstext Seite 16, letzter Abs.) eine wiederverschließbare Verpackung für feuchte Tücher aus einer feuchtigkeitsundurchlässigen Folie bekannt, die aber noch mit einer Umverpackung versehen ist, in der auch trockene Tücher enthalten sind.It is also known from EP-A-0 193 130 (Fig. 19 + 20 with description page 16, last paragraph) a reclosable packaging for wet wipes made of a moisture-impermeable film, but which is still provided with an outer packaging in which dry wipes are also included.

Hierbei ist jedoch die Verschlußklappe aus der feuchtigkeitsundurchlässigen Folie geformt, und mit einem Stanzschnitt ist eine Abdeckzunge in das flüssigkeitsundurchlässige Blatt eingearbeitet. Bei dieser Verpackung besteht jedoch die Gefahr, daß Flüssigkeit zwischen Einlegeblatt und der Verpackungsoberseite in den Bereich der Stanzlinie gelangen kann und dort zur Korrosion des Aluminiums führen kann, sofern die Verpackung aus einer Aluminium-Verbundfolie besteht, und dort aus der Packung austritt.Here, however, the closure flap is formed from the moisture-impermeable film, and a cover tongue is worked into the liquid-impermeable sheet with a punch cut. With this packaging, however, there is a risk that liquid between the insert sheet and the top of the packaging can get into the area of the punching line and there can lead to corrosion of the aluminum, provided that the packaging consists of an aluminum composite film and escapes from the packaging there.

Der Erfindung liegt daher die Aufgabe zugrunde, eine wiederverschließbare Verpackung für feuchte Tücher oder dergleichen der eingangs genannten Art so weiterzubilden, daß bei Verwendung einer Aluminium-Verbundfolie als feuchtigkeitsundurchlässige Folie unter Beibehaltung der bisherigen äußeren Form, insbesondere der gut greifbaren auf der Oberseite der Verpackung befestigten Verschlußklappe, auf einfache Weise ein gutes Abdichten der Perforationslinie bzw. des Stanzschnittes in der Folie ermöglicht, und somit eine Korrosion des Aluminiums vor dem ersten Öffnen verhindert wird und ein dichtes Wiederverschließen garantiert ist.The invention is therefore based on the object of developing a reclosable packaging for wet wipes or the like of the type mentioned in such a way that when using an aluminum composite film as a moisture-impermeable film while maintaining the previous outer shape, in particular the easy-to-grip fastened on the top of the packaging Closing flap, allows a simple sealing of the perforation line or the die cut in the film, thus preventing corrosion of the aluminum before the first opening and a tight reclosure is guaranteed.

Die Erfindung löst diese Aufgabe mit Hilfe der kennzeichnenden Merkmale der Ansprüche 1 bzw. 2.The invention solves this problem with the aid of the characterizing features of claims 1 and 2 respectively.

Bei der erfindungsgemäßen Verpackung wird durch die Kombination von Aluminium-Verbundfolie, Aufreißlasche, der diese überdeckenden Verschlußklappe und dem weit über die Ränder der Entnahmeöffnung ausgedehnten Zwischenblatt eine sichere Abdichtung erreicht. Wenn auch, wie bei der Verpackung gemäß EP-A- 0 193 130, ein wenig Flüssigkeit zwischen dem Blatt und der Verpackungsoberseite zum Stanzschnitt diffundieren sollte, so dichtet doch die Verschlußklappe sicher auf der Verpackungsoberseite ab. Ein weiterer Vorteil besteht darin, daß die erfindungsgemäße Verpackung gegenüber einer Verpackung mit einem geschlossenen Innenbeutel zur Aufnahme der feuchten Tücher preisgünstiger und einfacher herstellbar ist sowie die Zugänglichkeit der Tücher ohne größere Mühe gestattet. Bei dem üblichen Tränkungsgrad der Tücher reicht es nämlich aus, wenn die Aufreißlinie bzw. Anstanzung durch ein Blatt aus einer Kunststoffolie abgedeckt wird. Durch den Füllgrad der Verpackung mit den Tüchern wird dieses Blatt an die Innenseite der Verpakkungsfolie angepreßt, so daß keine Feuchtigkeit in den Bereich der Anstanzungen dringen kann. Dies vermeidet Flüssigkeitsaustritte aus den Stanzlöchern sowie Korrosionen der als Verpackungshülle verwendeten Aluminium-Verbundfolie.In the case of the packaging according to the invention, a secure seal is achieved by the combination of aluminum composite film, pull tab, the closure flap covering this and the intermediate sheet which extends far beyond the edges of the removal opening. Even if, as in the case of the packaging according to EP-A-0 193 130, a little liquid diffuses between the sheet and the top of the packaging for the die cut, the closure flap securely seals on the top of the packaging. Another advantage is that the packaging according to the invention is cheaper and easier to manufacture than packaging with a closed inner bag for holding the wet wipes and allows the wipes to be accessed with little effort. With the usual degree of impregnation of the wipes, it is in fact sufficient if the tear line or punching is covered by a sheet of a plastic film. Due to the degree of filling of the packaging with the cloths, this sheet is pressed against the inside of the packaging film, so that no moisture can penetrate into the area of the punchings. This avoids liquid leaks from the punch holes and corrosion of the aluminum composite film used as the packaging sleeve.

Mit einer weiteren Ausführungsform der Erfindung ist eine noch höhere Dichtigkeit zu erreichen, wenn nämlich das Blatt zwischen den feuchten Tüchern und der flachen Oberinnenseite der Folie im Bereich seiner Randzonen unlösbar mit der Folienunterseite verbunden ist und zur Entnahmemöglichkeit der feuchten Tücher eine Öffnung (Ausstanzung) aufweist, die kleiner als der durch die Aufreißlinie oder den Stanzschnitt gegebene Umriß ist. Nach Abziehen der haftenden Verschlußklappe wird eine Abdecklasche entlang der Anstanzung mitabgezogen, wodurch gleichzeitig die Entnahmeöffnung des Blattes freigelegt wird.With a further embodiment of the invention, an even higher tightness can be achieved if the sheet between the wet wipes and the flat inside of the film is inseparably connected to the underside of the film in the area of its edge zones and has an opening (punched out) for the removal of the wet wipes which is smaller than the outline given by the tear line or the die cut. After the adhesive flap has been pulled off, a cover flap is also pulled off along the stamping, thereby simultaneously exposing the removal opening of the sheet.

Die Erfindung wird im folgenden anhand von Zeichnungen dargestellt und näher erläutert. Es zeigen:

Die Verpackung besteht aus einer feuchtigkeitsundurchlässigen Kunststoff-Aluminium-Verbundfolie, deren Enden mittels Schweißnähten 1 und 2 in nach dem Stand der Technik bekannter Weise verbunden sind. Auf der Oberseite 3 der Verpackung ist ein zu öffnender Verschluß vorgesehen, durch den den Inhalt der Verpackung bildende Tücher entnommen werden können. Hierzu dient eine Entnahmeöffnung 4, die mittels einer Verschlußklappe 5 geöffnet und wieder verschlossen werden kann. Die Verschlußklappe 5 ist hierzu 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, zu der sie mittig angeordnet ist, so daß die Verschlußklappe 5 den Rand der Entnahmeöffnung 4 allseitig übergreift und somit im Verschlußzustand abdichtet. Die Entnahmeöffnung 4 ist gestanzt, wobei der ausgestanzte Teil aber nicht entfernt ist und beim Wiederverschließen der Verschlußklappe wieder zur Anlage kommen kann und somit als Abdeckzunge 9 das jeweils oberste Tuch abdeckt. Statt durchgehender Stanzlinien können auch Perforationslinien in der Oberseite 3 vorgesehen sein, wobei aber der der Griffzunge 8 zugewandte Bereich voll ausgestanzt ist, damit hier die Abdeckzunge 9 beim Öffnen an der Verschlußklappe 5 haften bleibt. Die Abdeckzunge 9 ist an ihrem der Griffzunge 8 gegenüberliegenden Ende nicht gestanzt, sondern hier einstückig mit dem Material der Oberseite 3 verbunden. Die Enden der Schenkel 10, 11 der Stanzung oder Perforation enden also blind. Durch diese Einstückigkeit wird erreicht, daß beim Verschließen die Abdeckzunge 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 die 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 auslaufen, womit ein Weiterreißen aufgrund der Kerbwirkung vermieden wird. Diese Bögen können ebenso auch nach innen gerichtet werden, ohne daß sich die Stanzschenkelenden berühren.The packaging consists of a moisture-impermeable plastic-aluminum composite film, the ends of which are connected by means of weld seams 1 and 2 in a manner known from the prior art. On the top 3 of the packaging, an opening is provided, through which the contents of the packaging can be removed. For this purpose, a removal opening 4 is used, which can be opened and closed again by means of a closure flap 5. For this purpose, the closure flap 5 is coated with a pressure-sensitive adhesive 6 and welded along its 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, to which it is arranged centrally, so that the closure flap 5 overlaps the edge of the removal opening 4 on all sides and thus seals in the closed state. The removal opening 4 is punched, but the punched-out part has not been removed and can come into contact again when the closure flap is closed and thus covers the top cloth in each case as a tongue 9. Instead of continuous punch lines, perforation lines can also be provided in the upper side 3, 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. The cover tongue 9 is not stamped on its end opposite the grip tongue 8, but is here connected in one piece to the material of the upper side 3. The ends of the legs 10, 11 of the punching or perforation thus end blind. This one-piece arrangement ensures that when the cover tongue is closed it lies exactly over 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, the stiffening or reinforcement takes place, thereby preventing tearing when opening. In addition or in addition, the ends of these punch legs 10, 11 can end in arches directed outwards to the side, thus preventing tearing due to the notch effect. These sheets can also be directed inwards without touching the ends of the punch legs.

Gegenüber den dargelegten verschiedenartigen Ausführungsformen der Erfindung besteht die Erfindung darin, gemäß der Darstellung in Figur 2 bzw. Figur 3 zwischen dem Stapel der Vliestücher 19 und der Innenseite der Oberseite der Verpackung 3 ein flüssigkeitsundurchlässiges Blatt 16 einzulegen. Dieses Blatt hat einen größeren Umriß als der durch die Entnahmeöffnung 4 vorgegebene und ist so dimensioniert, daß seine Abmessungen gleich oder größer sind als die Abmessungen der Verschlußklappe 5.Compared to the various embodiments of the invention described, the invention consists in inserting a liquid-impermeable sheet 16 between the stack of non-woven cloths 19 and the inside of the top of the packaging 3, as shown in FIG. 2 or FIG. 3. This sheet has a larger outline than that specified by the removal opening 4 and is dimensioned such that its dimensions are equal to or larger than the dimensions of the closure flap 5.

Das Blatt kann entweder lose eingelegt sein oder, wie in Fig. 4 angedeutet, in den Randbereichen 1 7a mit der Unterseite der Oberseite 3 verklebt sein. Dieses Blatt 17 besitzt dann jedoch eine Entnahmeöffnung 18, durch die nach Abziehen der Lasche 9 die Tücher 19 entnommen werden können.The sheet can either be inserted loosely or, as indicated in FIG. 4, be glued to the underside of the upper side 3 in the edge regions 17a. However, this sheet 17 then has a removal opening 18 through which the cloths 19 can be removed after the tab 9 has been pulled off.

Die Blätter 16 oder 17 können entweder aus einer Polyethylenfolie oder einer Aluminium-Verbundfolie bestehen. In jedem Falle ist durch Zwischenlage des Blattes 16 bzw. 17 dafür gesorgt, daß die Stanzlinien 10, 11 gegenüber den Tüchern 19 abgedeckt sind und somit in diesem Bereich keine von den Tüchern abgegebene Feuchtigkeit dringen kann. Hiermit werden ein frühzeitiger Feuchtigkeitsverlust sowie Korrosionen im Bereich der Anstanzung vermieden.The sheets 16 or 17 can consist of either a polyethylene film or an aluminum composite film. In any case, the interposition of the sheets 16 and 17 ensures that the punching lines 10, 11 are covered with respect to the sheets 19 and thus no moisture emitted by the sheets can penetrate into this area. This prevents premature loss of moisture and corrosion in the area of the punching.
