Abstract

The invention relates to a folding box with self-adhesive seal and a method for sealing the folding box. The folding box has a cover (6) which can be locked in the sealing position at one of its free edges by a mechanical locking (10, 11), flaps (14, 15) that can be folded in under the cover, and contact adhesive strips (17) with covering strips (19) able to be pulled off, for gluing the cover (6) together with the flaps (14, 15). The covering strips (19) have at their free end a tab (19a) that protrudes from the closed folding box. By pulling on the tab (19a), the covering strips (19) can be pulled out laterally under the cover (6) locked in sealing position, in order to glue the cover (6) together with the flaps (14, 15). On perforated tear lines (23), the middle section of the cover (6) can be opened again, without having to undo the adhesive connection in doing so. In use, the box is closed by first bringing the cover into the sealing position and locking it mechanically in this position and then, by pulling out the covering strips, exposing the contact adhesive strips and gluing the cover down.

Description

Die Erfindung betrifft eine Faltschachtel von der im Oberbegriff des Anspruchs 1 angegebenen Art. In US-A-4750609 ist eine Faltschachtel dieser Art beschrieben, deren Deckel wahlweise mittels Klebestreifen oder mittels Klettband als mechanischem Verriegelungsmittel in der Verschlußstellung fixiert werden kann.The invention relates to a folding box of the type in the preamble of claim 1. Specified in US-A-4750609 is a folding box of this type described, the lid either with adhesive tape or with Velcro as mechanical locking means in the closed position can be fixed.

Faltschachteln, bei denen der Deckel nur festgeklebt wird, sind beispielsweise aus DE-GBM-7208095 und DE-A-4226226 bekannt.Folding boxes, in which the lid is only glued, are for example from DE-GBM-7208095 and DE-A-4226226 known.

Ein Problem bei derartigen Faltschachteln besteht darin, daß in den Biegelinien des Deckels und der unter ihm eingefalteten Klappen Rückstellkräfte wirken, die die Klebeverbindung belasten und zu lösen suchen. Um eine sichere Verklebung zu erzielen, müssen Deckel und Klappen mit erheblichem Kraftaufwand gegeneinander gedrückt werden, und zwar so lange, bis eine vollflächige Verklebung erzielt ist. Der Schließvorgang bei derartigen Faltschachteln ist nicht optimal einfach, da gleichzeitig Klappen und Deckel in die Schließlage gefaltet und dort festgehalten werden müssen und der für die Herstellung der Klebeverbindung nötige Druck auf die Klebebereiche ausgeübt werden muß.A problem with such folding boxes is that in the bend lines of the lid and the one folded under it Flap restoring forces act on the adhesive bond burden and try to solve. For a secure bond To achieve, lids and flaps need to be considerable Force is pressed against each other until a full-surface bond is achieved. The The closing process for such folding boxes is not optimal easy, as flaps and lids enter the Folded closed position and must be held there and the one necessary for the production of the adhesive connection Pressure must be exerted on the adhesive areas.

Ein weiterer Nachteil besteht darin, daß das Freilegen der Klebeflächen durch Abziehen der Abdeckfolien erfolgen muß, bevor der Deckel in die Verschlußstellung bewegt wird. Dabei können die Klebestreifen leicht verschmutzen oder durch Berührung mit z. B. fettigen Fingern ihre Klebefähigkeit einbüßen. Außerdem besteht die Gefahr, daß beim Verschlußvorgang ein Verkleben bereits eintritt, wenn Deckel und/ oder Klappen noch nicht in der exakten endgültigen Verschlußlage sind. Daneben besteht das Problem, daß es bei herkömmlichen Faltschachteln möglich ist, ohne Aufreißen der Klebeverbindung den Deckel soweit hochzuheben, daß ein Spalt gebildet wird, durch den man in das Innere der Schachtel einsehen oder sogar den Inhalt entnehmen kann.Another disadvantage is that the exposure of the Adhesive surfaces must be done by pulling off the cover films, before the lid is moved to the closed position. Here can easily get dirty or through the adhesive strips Touch with z. B. greasy fingers their adhesiveness lose. There is also a risk that the closure process sticking already occurs when the cover and / or flaps are not yet in the exact final locking position are. There is also the problem that it conventional folding boxes is possible without tearing the adhesive connection to lift the lid so far that a Gap is formed through which one enters the interior of the View box or even extract the contents.

Der Erfindung liegt die Aufgabe zugrunde, eine Faltschachtel der genannten Art so zu verbessern, daß sowohl die Fixierung des Deckels in der Verschlußlage verbessert, die Faltschachtel dabei allseitig verschlossen als auch der Verschlußvorgang der Schachtel vereinfacht wird. Die erfindungsgemäße Lösung der Aufgabe ist im Anspruch 1 angegeben. Die Ansprüche 2 und 3 geben bevorzugte weitere Ausgestaltungen an.The invention has for its object a folding box of the type mentioned so that both the Fixing the lid in the closed position improved Folding box closed on all sides as well Closing process of the box is simplified. The The object of the invention is achieved in claim 1 specified. Claims 2 and 3 give preferred further Refinements.

Mit der erfindungsgemäßen Faltschachtel werden in vorteilhafter Weise die Vorgänge der Fixierung des Deckels in der Verschlußlage und der Herstellung der Klebeverbindung zwischen Deckel und Klappen funktionsmäßig voneinander getrennt. Der Deckel kann zuerst verschlossen und durch mechanische Verriegelung in der Verschlußlage fixiert werden, und anschließend können im bereits verschlossenen Zustand der Schachtel die Abdeckfolien seitlich unter dem Deckel herausgezogen und dadurch die Klebeverbindung zwischen Deckel und Klappen hergestellt werden.With the folding box according to the invention are advantageous Way of fixing the lid in the Closure position and the establishment of the adhesive connection between Functionally separated lid and flaps. The lid can be closed first and by mechanical Locking in the locked position can be fixed, and then in the already closed state the box has the cover films on the side under the lid pulled out and thereby the adhesive connection between Lids and flaps are made.

Die in Fig. 1 und 2 dargestellte Faltschachtel hat einen Boden 1, Seitenwände 2, 3, 4, 5 und einen Deckel 6, der über eine Biegelinie 7 mit der hinteren Seitenwand 2 zusammenhängt. An seiner zur Biegelinie 7 parallelen freien Kante 8 ist der Deckel 6 mit einer abgewinkelten Zunge 9 mit einem Schlitz 10 versehen. In den Schlitz 10 kann eine an der vorderen Seitenwand 3 angebrachte Zunge 11 eingesteckt werden, um den Deckel 6 in der Verschlußlage (Fig. 2) mechanisch zu verriegeln. Mittels einer von der Zunge 11 nach außen vorstehenden Grifflasche 12 kann die Zunge 11 aus dem Schlitz 10 herausgezogen werden, um die Verriegelung zu lösen.The folding box shown in Figs. 1 and 2 has one Bottom 1, side walls 2, 3, 4, 5 and a lid 6, the is connected to the rear side wall 2 via a bending line 7. On its free parallel to the bending line 7 Edge 8 is cover 6 with an angled tongue 9 provided with a slot 10. In the slot 10 can on the front side wall 3 attached tongue 11 inserted the cover 6 in the closed position (Fig. 2) lock mechanically. By means of a tongue 11 the tab 11 projecting outwards can the tongue 11 be pulled out of the slot 10 to lock to solve.

An den zur Biegelinie 7 des Deckels 6 rechtwinklig verlaufenden Seitenwänden 4, 5 ist je eine einfaltbare Staubklappe 14, 15 vorgesehen, die im gefalteten Zustand unter dem Deckel 6 liegt und von diesem überlappt wird. Jede Staubklappe 14, 15 ist parallel zu ihrer Faltkante mit Klebeflächen 17, insbesondere in Form von Klebestreifen, versehen, die mit einer leicht abziehbaren Abziehfolie 19, insbesondere einem Abdeckstreifen, abgedeckt sind. Ein Anfaßteil 19a jeder Abziehfolie 19 steht nach vorne über die vordere Seitenwand 3 über. Bei der Ausführungsform haben die Klebeflächen 17 und Abziehfolien 19 die Form von Streifen, die sich durchgehend über die Länge jeder Staubklappe erstrecken.At the right angles to the bending line 7 of the cover 6 Side walls 4, 5 is a foldable dust flap 14, 15 provided in the folded state under the cover 6 lies and is overlapped by this. Each Dust flap 14, 15 is parallel to its folded edge Adhesive surfaces 17, in particular in the form of adhesive strips, provided with an easily removable peelable film 19, in particular a cover strip are covered. On Grip part 19a of each release liner 19 projects forward the front side wall 3 over. In the embodiment have the adhesive surfaces 17 and release films 19 in the form of Stripes that run continuously along the length of each Extend dust flap.

Zum Verschließen der Faltschachtel werden zuerst die Staubklappen 14, 15 eingefaltet und dann der Deckel 6 in die Verschlußstellung gebracht und durch Einstecken der Zunge 11 in den Schlitz 10 fixiert, so daß der Zustand gemäß Fig. 2 erreicht wird. Anschließend können die über die vordere Seitenwand 3 überstehenden Anfaßteile 19a der Abziehfolien 19 ergriffen und diese seitlich unter dem Deckel 6 herausgezogen werden, wie in Fig. 2 durch den Pfeil 21 angedeutet. Hierdurch werden unter dem geschlossenen Deckel 6 die Kontaktklebeflächen 17 freigelegt, und durch Druck auf die entsprechenden Bereiche des Deckels 6 können diese mit den darunter befindlichen Staubklappen 14, 15 verklebt werden.To close the folding box, first the dust flaps 14, 15 folded and then the lid 6 in the Locked position and by inserting the tongue 11 fixed in the slot 10, so that the state shown in FIG. 2 is reached. Then you can use the front Side wall 3 projecting grip parts 19a of the peel-off films 19 gripped and pulled out laterally under the cover 6 are, as indicated in Fig. 2 by the arrow 21. As a result, 6 the contact adhesive surfaces 17 exposed, and by pressing the corresponding areas of the cover 6 can with these the dust flaps 14, 15 located below are glued.

Das Abziehen der Abziehfolie 19 von den Klebeflächen 17 erfolgt bei geschlossenem Deckel 6 vorzugsweise so, daß die Schutzfolien 19 nach oben umgeknickt und jeweils von der Faltschachtel nach außen, über sich selbst weggezogen werden. Diese Art und Weise des Herausziehens der Abdeckfolien 19 kann insbesondere dadurch erleichtert werden, daß die Anfaßteile 19a der Schutzfolien 19 in ausreichender Länge von der Faltschachtel abstehen und darin ein geeigneter Knick 20 vorgefalzt wird, der die Abziehbewegung indiziert. In den Figuren 3a und 3b sind in Detailzeichnungen der Faltschachtel nach Fig. 2 zwei Ausführungsformen eines solchen mit einem Knick versehenen Anfaßteils 19a dargestellt.Removing the peel-off film 19 from the adhesive surfaces 17 is preferably done with the lid 6 closed so that the Protective films 19 folded upwards and each of the Folding box to the outside, pulled over itself. This way of pulling out the cover films 19 can in particular be facilitated in that the Grip parts 19a of the protective films 19 in sufficient length protrude from the box and a suitable one in it Kink 20 is pre-folded, which indicates the peeling movement. In Figures 3a and 3b are in detailed drawings Folding box according to FIG. 2 two embodiments of one such a handle portion 19a provided with a kink shown.

Die über den Staubklappen 14, 15 liegenden seitlichen Bereiche 16 des Deckels 6 sind vom mittleren Teil des Deckels durch Perforationslinien 23 getrennt. Dies erleichtert das Öffnen der Schachtel, da hierbei nicht die Klebeverbindung an den Klebeflächen 17 gelöst zu werden braucht, sondern lediglich der mittlere Teil des Deckels 6 entlang der Perforationslinien 23 von den Seitenteilen 16 getrennt wird. Dabei kann jede Perforationslinie 23 vorzugsweise auch als doppelte Perforationslinie beiderseits eines Reißstreifens 22 ausgebildet sein, der eine komfortable und zuverlässige Trennung des mittleren Deckelteils von den seitlichen Bereichen 16 des Deckels ermöglicht. Ein solcher Reißstreifen 22 ist in Fig. 4 nur im rechten Teil des Deckels 6 dargestellt, kann aber selbstverständlich entsprechend auch im linken Teil des Deckels 6 ausgebildet sein. Außerdem können bei geschlossenem, aber noch nicht verklebtem Deckel die Seitenteile 16 des Deckels leicht entlang der Perforationslinien 23 gegenüber dem Mittelteil des Deckels 6 etwas angehoben werden, um das Herausziehen der Abdeckfolien 19 unter dem Deckel 6 zu erleichtern.The lateral areas lying above the dust flaps 14, 15 16 of the lid 6 are from the central part of the lid separated by perforation lines 23. This makes it easier Open the box as this is not the adhesive connection need to be solved on the adhesive surfaces 17, but only the middle part of the lid 6 along the perforation lines 23 is separated from the side parts 16. Each perforation line 23 can preferably also be a double line of perforations on both sides of a tear strip 22 designed to be comfortable and reliable Separation of the middle lid part from the side areas 16 of the lid allows. Such a tear strip 22 is shown in Fig. 4 only in the right part of the cover 6, can of course also in left part of the cover 6 may be formed. You can also with the lid closed but not yet glued the Side parts 16 of the lid slightly along the perforation lines 23 slightly raised relative to the middle part of the cover 6 to pull out the cover films 19th to facilitate under the lid 6.

Eine weitere Ausführungsform einer erfindungsgemäßen Faltschachtel ist in Figur 4 dargestellt. Bei dieser Ausführungsform sind die einfaltbaren Staubklappen 14, 15 von den Seitenwänden 4, 5 zur Faltschachtelmitte hin jeweils so weit verlängert, daß in geschlossenem Zustand die Perforationslinien 23 bzw. die Reißstreifen 22 auf den eingefalteten Staubklappen 14, 15 aufliegen und sich die eingefalteten Staubklappen 14, 15 mit dem durch die Perforationslinien 22, 23 begrenzten Mittelteil des Deckels 6 mindestens teilweise überlappen. Außerdem sind an den von der Biegelinie 7 entfernten freien Kanten der Staubklappen 14, 15 jeweils zusätzliche nach unten abgewinkelte Klappen 24, 25 vorgesehen, um zu verhindern, daß bei verklebtem Deckel durch Hochziehen des Deckels 6 und damit der Staubklappen 14 oder 15 ein Spalt zwischen den Staubklappen 14, 15 und der Oberkante der vorderen Seitenwand 3 geöffnet werden kann, entsteht, durch den der Inhalt der Faltschachtel eingesehen oder entnommen werden könnte.Another embodiment of a folding box according to the invention is shown in Figure 4. In this embodiment are the foldable dust flaps 14, 15 of the Side walls 4, 5 towards the middle of the carton each so extended that the perforation lines in the closed state 23 or the tear strips 22 on the folded Dust flaps 14, 15 rest and the folded ones Dust flaps 14, 15 with the through the perforation lines 22, 23 limited middle part of the cover 6 at least partially overlap. In addition, those of the Bending line 7 removed free edges of the dust flaps 14, 15 additional flaps 24 angled downwards, 25 provided to prevent that when the lid is glued by pulling up the cover 6 and thus the dust flaps 14 or 15 a gap between the dust flaps 14, 15 and the upper edge of the front side wall 3 can be opened can, arises through which the contents of the folding box can be viewed or could be removed.

Darüber hinaus ist die abgewinkelte Zunge 9 entlang der zur Biegelinie 7 parallelen freien Kante 8 des Deckels 6 derart verlängert, daß sie sich mit den nach unten abgewinkelten Klappen 24, 25 der einfaltbaren Staubklappen 14, 15 im geschlossenen Zustand mindestens teilweise überlappt. Damit ist ein allseitiger Verschluß der Faltschachtel gewährleistet, und ein Einblick auf den Inhalt oder eine Entnahme ohne sichtbare Beschädigung der Faltschachtel unmöglich.In addition, the angled tongue 9 along the to Bending line 7 parallel free edge 8 of the lid 6 such lengthened so that they are bent downwards Flaps 24, 25 of the foldable dust flaps 14, 15 in the closed Condition at least partially overlapped. In order to the carton is sealed on all sides, and an insight into the content or an extraction impossible without visible damage to the folding box.

Die Erfindung ist nicht auf die Einzelheiten der dargestellten Ausführungsform beschränkt. Beispielsweise können die Kontaktklebeflächen 17 mit Abdeckfolien 19 statt an den Staubklappen 14, 15 auch an der Unterseite des Deckels 6 vorgesehen werden. Die Klappen, und damit auch die Klebeflächen zur Verbindung der Klappen mit dem Deckel können auch an anderen Seitenwänden, z. B. an der vorderen Seitenwand 3 angebracht sein.The invention is not shown on the details of the Embodiment limited. For example the contact adhesive surfaces 17 with cover 19 instead of the Dust flaps 14, 15 also on the underside of the cover 6 be provided. The flaps, and thus also the adhesive surfaces to connect the flaps to the lid also on other side walls, e.g. B. on the front side wall 3 be attached.

Sowohl die mit Kontaktkleber versehenen Flächenbereiche 17 als auch deren Abdeckfolien 19 müssen nicht als Streifen ausgebildet sein, sondern können eine beliebige Gestalt haben. Darüber hinaus müssen die Kontaktklebeflächen 17 nicht notwendigerweise als eine zusammenhängende Fläche geformt sein, sondern können auch in eine Anzahl von einzelnen Teilflächen unterteilt sein.Both the surface areas 17 provided with contact adhesive as well as their cover sheets 19 do not have to be strips be trained, but can be any shape to have. In addition, the contact adhesive surfaces 17 not necessarily shaped as a coherent surface but can also be in a number of individual Subareas can be divided.

Ebenso kann die Abdeckfolie 19 aus mehreren voneinander getrennten Teilen bestehen, wird aber vorzugsweise als ein zusammenhängender Streifen gestaltet. Die Abdeckfolien 19 können aus jedem Material gefertigt sein, das die Eigenschaft hat, von Kontaktklebeflächen leicht abziehbar zu sein, wie z.B. beschichteter Kunststoff oder Papier. Ferner kann der Kontaktkleber selbst durch ein beliebiges adhäsives Vebindungsmittel ersetzt oder ergänzt werden.Likewise, the cover sheet 19 can consist of several separate ones Share exist, but is preferably considered a coherent stripes. The cover films 19 can be made of any material that has the property has, easily removable from contact adhesive surfaces be such as coated plastic or paper. Further the contact adhesive can be replaced by any adhesive bonding agent can be replaced or supplemented.
