Description

Die Erfindung betrifft ein Schutzsystem für ein Papierprodukt mit zwei rückseitig gegeneinander schwenkbar verbundenen Deckeln umfassend eine Schutzfolie zum Schutz der Deckel des Papierprodukts, wobei die Schutzfolie zwei gegenüberliegend angeordnete Längskanten und zwei jeweils zwischen den Längskanten verlaufende Querseiten aufweist.The invention relates to a protective system for a paper product with two lids pivotally connected to each other at the back comprising a protective film for protecting the lids of the paper product, the protective film having two oppositely disposed longitudinal edges and two transverse sides extending between the longitudinal edges.

Zum Schutz von Papierprodukten wie beispielsweise Büchern, Heften oder Ordnern ist es bereits bekannt, Folien auf die Außenseiten der Deckel zu kleben. Eine Korrektur von handwerklichen Fehlern ist dabei in der Regel ebenso unmöglich wie der Tausch beschädigter oder verschmutzter Folien.For the protection of paper products such as books, booklets or folders, it is already known to glue films on the outer sides of the lid. A correction of manual errors is usually just as impossible as the exchange of damaged or soiled slides.

Es sind daher auch klebefreie Folienumschläge in vorgefertigten Größen entwickelt worden, die Taschen oder Laschen aufweisen, in die die Deckel des Papierprodukts eingesteckt werden. Eine derartige Befestigung ist jedoch nur dann ausreichend alltagstauglich, wenn die Abmessungen von Umschlag und Papierprodukt zueinander passen, da der Umschlag sonst unbeabsichtigt abrutschen und seine Schutzfunktion so verlieren kann.Therefore, tack-free film envelopes have also been developed in prefabricated sizes which have pockets or tabs into which the lids of the paper product are inserted. However, such an attachment is only sufficiently suitable for everyday use, if the dimensions of the envelope and paper product match each other, since the envelope otherwise slip off unintentionally and thus lose its protective function.

Es wurden auch bereits vielfältige Anstrengungen unternommen, in der Größe variable folienbasierte Schutzmöglichkeiten für Bücher, Hefte und Ordner zu entwickeln, die bisher jedoch in der Herstellung aufwendig und entsprechend teuer oder in der Anwendung kompliziert und unkomfortabel sind.Various efforts have also been made to develop variable sheet-based protection options for books, booklets and folders in size, but so far in the production complicated and correspondingly expensive or complicated to use and uncomfortable.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Alternative zu bekannten größenvariablen folienbasierten Schutzsystemen für ein Papierprodukt bereitzustellen, wobei insbesondere eine leichte Größenanpassung, eine unkomplizierte Anwendung und eine günstige Herstellung erreicht werden sollen.Based on this prior art, the present invention seeks to provide an alternative to known variable size sheet-based protection systems for a paper product, in particular, a slight size adjustment, a straightforward application and a favorable production to be achieved.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein Schutzsystem für ein Papierprodukt mit zwei rückseitig gegeneinander schwenkbar verbundenen Deckeln umfassend eine Schutzfolie zum Schutz der Deckel des Papierprodukts, wobei die Schutzfolie zwei gegenüberliegend angeordnete Längskanten und zwei jeweils zwischen den Längskanten verlaufende Querseiten aufweist, wobei das erfindungsgemäße Schutzsystem dadurch weitergebildet ist, dass die Schutzfolie an einer der Querseiten eine zweiseitig offene Tasche zum Einstecken einer Vorderkante eines der Deckel des Papierprodukts aufweist, die an dieser Querseite sowie an einer der Längskanten geschlossen ist, wobei das Schutzsystem ferner wenigstens drei flächige Klebeverschlüsse zum Schließen der zweiseitig offenen Tasche sowie einer an der gegenüberliegenden Querseite durch Einschlagen der Schutzfolie gebildeten dreiseitig offenen Tasche jeweils über eine Längskante der Schutzfolie hinweg umfasst, wobei die Klebeverschlüsse jeweils wenigstens zwei Klebebereiche und einen zwischen den Klebebereichen angeordneten Faltbereich aufweisen.This object is achieved by a protective system for a paper product with two mutually pivotally connected lids back comprising comprising a protective film to protect the lid of the paper product, wherein the protective film has two oppositely disposed longitudinal edges and two each extending between the longitudinal edges transverse sides, wherein the protection system according to the invention is further developed in that the protective film has on one of the transverse sides of a two-sided open pocket for insertion of a front edge of the lid of the paper product, which is closed at this transverse side and at one of the longitudinal edges, wherein the protection system further comprises at least three flat adhesive closures for closing the bag which is open on both sides and a three-sided open pocket formed on the opposite transverse side by wrapping in the protective film in each case covers over a longitudinal edge of the protective film, the adhesive closures each having at least two adhesive regions and a folding region arranged between the adhesive regions.

Die erfindungsgemäß vorgesehene zweiseitig offene Tasche ermöglicht durch die beiden über eck angeordneten geschlossenen Seiten eine einfache Ausrichtung des Papierprodukts relativ zu der Folie und vereinfacht so die Handhabung bei der Anwendung des erfindungsgemäßen Schutzsystems. Erfindungsgemäß ist insbesondere vorgesehen, dass die zweiseitig offene Tasche bereits bei der Herstellung des Schutzsystems geschaffen wird. Sie ist, mit anderen Worten, bereits vor Beginn der bestimmungsgemäßen Anwendung des erfindungsgemäßen Schutzsystems zum Schutz eines Papierprodukts vorhanden und unterscheidet sich dadurch von den erst während der bestimmungsgemäßen Anwendung der Erfindung gebildeten Taschen in der Schutzfolie.The inventively provided two-sided open pocket allows through the two arranged on eck closed pages a simple orientation of the paper product relative to the film and thus simplifies the handling of the application of the protection system according to the invention. According to the invention it is provided in particular that the two-sided open pocket is already created in the production of the protection system. In other words, it is present before the intended use of the protective system according to the invention for the protection of a paper product and differs from the pockets formed in the protective film only during the intended use of the invention.

Da die zweiseitig geschlossene Tasche an einer Längskante offen ist, kann ohne Weiteres die Schutzfolie parallel zu dieser Seitenkante abgeschnitten werden, um die Breite der Schutzfolie zwischen den beiden Längskanten an eine Länge der Vorderkante des Deckels des Papierprodukts anzupassen.Since the two-sided closed pocket is open at one longitudinal edge, the protective film can be easily cut off parallel to this side edge to adapt the width of the protective film between the two longitudinal edges to a length of the front edge of the lid of the paper product.

Eine zweite Tasche für den anderen Deckel des Papierprodukts wird durch Umschlagen eines Seitenabschnitts der Schutzfolie an der der zweiseitig offenen Tasche gegenüberliegenden Querseite der Schutzfolie ermöglicht. Dabei kann der Abstand der beiden Taschen durch Umschlagen eines Seitenabschnitts geeigneter Breite an eine Umfangsabmessung des Papierprodukts angepasst werden. Die Umfangsabmessung wird dabei insbesondere durch eine Breite der Deckel sowie eines gegebenenfalls zwischen den Deckeln vorhandenen Rückens des Papierprodukts bestimmt.A second pocket for the other lid of the paper product is made possible by folding over a side portion of the protective film at the transverse side of the protective film opposite the two-sided open pocket. In this case, the distance of the two pockets can be adapted by turning over a side portion of suitable width to a circumferential dimension of the paper product. The circumferential dimension is determined in particular by a width of the lid and an optionally existing between the covers back of the paper product.

Eine besonders einfache Herstellung des erfindungsgemäßen Schutzsystems wird ermöglicht, wenn die zweiseitig offene Tasche gebildet ist durch Umschlagen eines Seitenabschnitts der Schutzfolie und Herstellung einer Verbindung zwischen dem Seitenabschnitt mit einem nach dem Umschlagen deckungsgleich mit dem Seitenabschnitt angeordneten Mittelabschnitt der Schutzfolie entlang einer der Längskanten. In diesem Zusammenhang wird unter einer Verbindung insbesondere eine dauerhafte Verbindung der beiden Folienabschnitte verstanden, die vorzugsweise nicht zerstörungsfrei gelöst werden kann.A particularly simple production of the protective system according to the invention is made possible when the two-sided open pocket is formed by turning over a side section of the protective film and establishing a connection between the side section with a cover section arranged congruently with the side section of the protective film along one of the longitudinal edges. In this context, a connection is understood to mean, in particular, a permanent connection of the two film sections, which can preferably not be released in a non-destructive manner.

Von der Erfindung sollen dabei alle geeigneten Verbindungsverfahren umfasst sein. Die Verbindung kann beispielsweise als Klebeverbindung oder als Schmelzverbindung oder als Schweißverbindung ausgebildet sein. In der Herstellung besonders einfach zu realisieren und daher bevorzugt ist dabei eine als Stanzverbindung ausgebildete Verbindung. Wenn die Stanz- oder Prägeverbindung dabei mit einer erhitzen Prägevorrichtung erzeugt wird, ergibt sich vorteilhafterweise ein zusätzliches Verschweißen der beiden Folienabschnitte.In this case, all suitable connection methods should be encompassed by the invention. The compound may be formed, for example, as an adhesive bond or as a fusion or as a welded joint. In the production particularly easy to implement and therefore preferred is a trained as a stamped connection. If the punching or embossing connection is produced with a heated embossing device, this advantageously results in additional welding of the two film sections.

Im Rahmen der Erfindung können auch mehrere Verbindungsverfahren kombiniert werden, um beispielsweise ein besonders dauerhafte und widerstandsfähige Verbindung zu erhalten. Insbesondere ist daran gedacht, eine zuerst als Stanz- oder Prägeverbindung hergestellt Verbindung zusätzlich durch Kleben und/oder Schweißen zu verstärken.In the context of the invention, several connection methods can be combined in order to obtain, for example, a particularly durable and resistant connection. In particular, it is envisaged to additionally reinforce a connection produced as a stamping or stamping connection by gluing and / or welding.

Die Anpassung des erfindungsgemäßen Schutzsystems an gängige Formate von Papierprodukten wird erheblich vereinfacht, wenn die Schutzfolie Schnittmarkierungen für vorgegebene Formate aufweist zum geeigneten Einkürzen der Schutzfolie parallel zu den Längskanten.The adaptation of the protection system according to the invention to common formats of paper products is considerably simplified if the protective film has cut marks for predetermined formats for suitable shortening of the protective film parallel to the longitudinal edges.

Das erfindungsgemäße Schutzsystem umfasst ferner wenigstens drei Klebeverschlüsse, um an den Längskanten der Schutzfolie die verbleibenden Öffnungen der Taschen zu verschließen. Hierfür wird ein erster Klebebereich eines Klebeverschlusses derart an der Schutzfolie angebracht, dass der Faltbereich entlang der entsprechenden Längskante ausgerichtet ist und der andere Klebebereich über die Schutzfolie übersteht. Anschließend wird der Klebeverschluss entlang des Faltbereichs gefaltet, so dass der vormals überstehende Klebebereich an der Anderen Seite der Taschenöffnung an der Schutzfolie angebracht werden kann.The protection system according to the invention further comprises at least three adhesive seals in order to close the remaining openings of the pockets on the longitudinal edges of the protective film. For this purpose, a first adhesive region of an adhesive closure is attached to the protective film such that the folding region is aligned along the corresponding longitudinal edge and the other adhesive region projects beyond the protective film. Subsequently, the adhesive seal along the Folded folding area, so that the former protruding adhesive area on the other side of the pocket opening can be attached to the protective film.

Wenn das Schutzsystem vier Klebeverschlüsse umfasst, so steht auch für die bereits geschlossene Seite der zweiseitig geschlossenen Tasche ein Klebeverschluss bereit. Dies ermöglicht einerseits die zusätzliche Stabilisierung der geschlossenen Seite der Tasche und führt anderseits zu einer symmetrischen und somit ästhetisch ansprechenderen Anordnung der Klebeverschlüsse.If the protection system comprises four adhesive closures, an adhesive seal is also available for the already closed side of the two-sided closed pocket. This allows on the one hand the additional stabilization of the closed side of the bag and on the other hand leads to a symmetrical and thus more aesthetically pleasing arrangement of the adhesive closures.

Besonders einfach herzustellen und anzuwenden ist ein erfindungsgemäßes Schutzsystem, bei dem die Klebebereiche der Klebeverschlüsse selbstklebend ausgebildet sind. Dabei ist es denkbar, dass eine einzige Kleberfläche sowohl die vorgesehenen Klebebereiche als auch die Faltbereiche bedeckt. Wenn die Faltebereiche jedoch frei von Kleber sind wird ein unbeabsichtigtes Eindringen von Kleber in die Tasche und damit eine potenzielle Verschmutzung des Papierprodukts jedoch dauerhaft ausgeschlossen.Particularly easy to manufacture and use is an inventive protection system in which the adhesive areas of the adhesive closures are self-adhesive. It is conceivable that a single adhesive surface covers both the intended adhesive areas and the folding areas. However, when the creases are free of adhesive, inadvertent entry of glue into the pocket and thus potential fouling of the paper product is permanently eliminated.

Eine besonders bevorzugte Weiterbildung der Erfindung ist dadurch ausgezeichnet, dass die Klebeverschlüsse jeweils drei Klebebereiche mit zwei dazwischenliegenden Faltbereichen aufweisen, wobei die beiden Faltbereichen insbesondere im Wesentlichen rechtwinklig zueinander angeordnet sind.A particularly preferred embodiment of the invention is characterized in that the adhesive closures each have three adhesive areas with two intermediate fold areas, wherein the two fold areas are arranged in particular substantially at right angles to each other.

Diese weitergebildeten Klebeverschlüsse werden dabei in den Ecken der Schutzfolie angewendet. Dabei wird beispielsweise zunächst eine der drei Klebereiche derart angebracht, dass der der an diesen Klebebereich angrenzende Faltbereich parallel zu einer Seitenkante der Schutzfolie ausgerichtet ist und der zweite Faltbereich fluchtend mit einer Kante der Schutzfolie an einer der Querseiten ausgerichtet ist. Der Klebeverschluss wird nacheinander an beiden Faltbereichen gefaltet, so dass der Klebeverschluss eine Ecke der Schutzfolie sowohl entlang der angrenzenden Längskante als auch an der angrenzenden Querseite umschlingt. Dadurch wird neben einem Verschluss für eine der Taschen in der Schutzfolie zusätzlich ein verbesserter Kantenschutz für das Papierprodukt ermöglicht.These trained adhesive closures are applied in the corners of the protective film. In this case, for example, at first one of the three adhesive regions is attached in such a way that the folding region adjoining this adhesive region is aligned parallel to a side edge of the protective film and the second folding region is aligned with one edge of the protective film on one of the transverse sides. The adhesive closure is folded one after the other at both fold areas, such that the adhesive closure wraps around a corner of the protective film both along the adjacent longitudinal edge and on the adjacent transverse side. As a result, in addition to a closure for one of the pockets in the protective film, an improved edge protection for the paper product is additionally made possible.

Dabei kommen bei bestimmungsgemäßer Anwendung abschließend zwei Klebebereiche übereinanderliegend zur Anordnung. Vorteilhaft ist daher, wenn bei den Klebeverschlüssen jeweils zwei an einen Faltbereich angrenzende Klebebereiche im Wesentlich spiegelbildlich zueinander geformt sind. Die übereinanderliegenden Klebebereiche sind dann im Wesentlichen deckungsgleich.When used as intended, finally two adhesive areas are superimposed on the arrangement. It is therefore advantageous if in the case of the adhesive closures, in each case two adhesive areas adjoining a folding area are formed substantially mirror-inverted relative to one another. The superposed adhesive areas are then substantially congruent.

Zur einfacheren Anwendung umfasst ein erfindungsgemäßes Schutzsystem vorzugsweise ferner eine schriftliche Gebrauchsanleitung mit geeigneten Handlungsanweisungen für:

  • ein Anpassen der Schutzfolie an die Höhe der Deckel des Papierprodukts durch optionales Einkürzen der Schutzfolie parallel zu der Längskante, an der die zweiseitig offene Tasche der Schutzfolie offen ist;
  • ein Anpassen der Schutzfolie quer dazu durch geeignetes Umschlagen eines Seitenabschnitts der Folie an der der zweiseitig offenen Tasche gegenüberliegenden Querseite, so dass sich eine dreiseitig offene Tasche ergibt und
  • ein bestimmungsgemäßes Anbringen der umfassten Klebeverschlüsse, um die beiden Taschen an den beiden Längskanten der Schutzfolie zu schließen.
For ease of use, a protection system according to the invention preferably further comprises a written instruction manual with suitable instructions for:
  • adjusting the protective film to the height of the lids of the paper product by optionally shortening the protective film parallel to the longitudinal edge where the two-sided open pocket of the protective film is open;
  • adjusting the protective film transversely thereto by suitably turning over a side section of the film at the transverse side opposite the two-sided open pocket, so that a three-sided open pocket results and
  • a proper attachment of the included adhesive closures to close the two pockets at the two longitudinal edges of the protective film.

FIG. 2 shows a protection system 1 according to the invention, which inter alia for the exemplary in Fig. 1 shown book 30 is suitable. The protective system 1 comprises a protective film 10 and a plurality of adhesive closures 20. The substantially rectangular protective film 10 has two longitudinal edges 11, 12 and two transverse sides 13, 14. On one transverse side 13, the protective film 10 has a pocket 15, which is closed on the longitudinal side 11 and open on the other longitudinal side 12.

Die Tasche 15 ist dadurch gebildet, dass ein Seitenabschnitt 18 der Schutzfolie 10 an einer entlang der Querseite 13 verlaufenden Linie umgeschlagen und/oder gefaltet ist. Anschließend wurde der Seitenabschnitt 18 entlang der Längskante 11 mit dem darunterliegenden Abschnitt der Schutzfolie 10 verbunden, so dass die Tasche 15 an dieser Seite geschlossen wurde. Die Verbindung 19 ist in dem gezeigten Ausführungsbeispiel als Schweißprägeverbindung ausgebildet, wobei sich die mittels erhitztem Prägestempel erzeugten Prägestellen herstellungsbedingt über die gesamte Länge der Schutzfolie 10 entlang der Längskante 11 erstrecken.The pocket 15 is formed by a side section 18 of the protective film 10 being folded over and / or folded along a line running along the transverse side 13. Subsequently, the side portion 18 was joined along the longitudinal edge 11 to the underlying portion of the protective film 10, so that the bag 15 was closed at this side. In the exemplary embodiment shown, the connection 19 is designed as a weld-stamping connection, with the embossing points produced by means of a heated stamping die extending along the longitudinal edge 11 over the entire length of the protective film 10 as a result of the production.

Figur 3a zeigt im Detail einen der Klebeverschlüsse 20. Der Klebeverschluss 20 ist im Wesentlichen flächig ausgebildet und umfasst drei Klebebereiche 22, wobei jeweils zwischen zwei benachbarten Klebebereichen 22 ein Faltbereich 24 vorgesehen ist. FIG. 3a shows in detail one of the adhesive closures 20. The adhesive closure 20 is formed substantially flat and comprises three adhesive areas 22, wherein in each case between two adjacent adhesive areas 22 a folding area 24 is provided.

Der Klebeverschluss 20 ist beispielsweise zumindest an den Klebebereichen 22 einseitig selbstklebend ausgebildet. Bei alternativen Ausführungen der Erfindung kann jedoch auch separater Kleber zum Anbringen der Klebeverschlüsse 20 verwendet werden.The adhesive closure 20 is, for example, at one end self-adhesive at least on the adhesive areas 22. However, in alternative embodiments of the invention, separate adhesive may also be used to apply the adhesive seals 20.

Eine alternative, einfacher aufgebaute Variante eines erfindungsgemäßen Klebeverschlusses 20' ist in Fig. 3b gezeigt. Dieser Klebeverschluss 20' weist lediglich zwei Klebebereiche 22 mit einem dazwischenliegenden Faltbereich 24 auf. Figur 4 illustriert exemplarisch die Befestigung der Schutzfolie 10 an den Buchdeckeln 31 des Buches 30. Ebenfalls wird anhand Fig. 4 ersichtlich, wie die Schutzfolie 10 an die Größe des Buches 30 angepasst werden kann.An alternative, simpler constructed variant of an adhesive closure 20 'according to the invention is shown in FIG Fig. 3b shown. This adhesive closure 20 'has only two adhesive regions 22 with an intermediate fold region 24. FIG. 4 illustrates by way of example the attachment of the protective film 10 to the book covers 31 of the book 30. Also, reference is made Fig. 4 it can be seen how the protective film 10 can be adapted to the size of the book 30.

Zunächst wird das Buch 30 geöffnet und einer der Buchdeckel 31 in die zweiseitig offene Tasche 15 eingesteckt. Die Verbindung 19 an der Tasche 15 dient dabei als Richthilfe, um die Unterseite der Buchdeckel 31 entlang der Längskante 11 der Schutzfolie 10 auszurichten. Entlang der gegenüberliegenden Längskante 12 wird die Schutzfolie 10 durch einen geeignet platzierten Schnitt 41 an die Höhe der Buchdeckel 31 angepasst. In der Regel ist es dabei hilfreich, wenn die Schutzfolie 10 geringfügig größer als die Buchdeckel 31 zugeschnitten wird. Vorteilhaft sind auf der Schutzfolie bereits Schnittmarkierung für gängige Formate, beispielsweise DIN A4 und/oder DIN A5, angebracht, um das Zuschneiden zu erleichtern.First, the book 30 is opened and one of the book cover 31 is inserted into the two-sided open pocket 15. The connection 19 on the pocket 15 serves as a directional aid to align the underside of the book cover 31 along the longitudinal edge 11 of the protective film 10. Along the opposite longitudinal edge 12, the protective film 10 is adjusted by a suitably placed section 41 to the height of the book cover 31. In general, it is helpful if the protective film 10 is cut slightly larger than the book cover 31. Advantageously, cut marks for common formats, for example DIN A4 and / or DIN A5, are already mounted on the protective film in order to facilitate the cutting.

Für den anderen Buchdeckel 31 wird ebenfalls eine Tasche 15' gebildet, indem an der Querseite 14 ein Seitenabschnitt 17 der Schutzfolie 10 entlang einer geeignet platzierten Faltlinie 42 umgeschlagen und/oder gefaltet wird, wie schematisch durch den Pfeil 43 dargestellt ist. Dadurch kommt die Seitenkante 16 der Schutzfolie 10 auf der strichpunktierten Linie 16' zu liegen. Die Tasche 15' ist somit zunächst dreiseitig offen.For the other book cover 31, a pocket 15 'is also formed by folding and / or folding a side section 17 of the protective film 10 along a suitably placed fold line 42 on the transverse side 14, as shown schematically by the arrow 43. As a result, the side edge 16 of the protective film 10 comes to lie on the dot-dash line 16 '. The bag 15 'is therefore initially open on three sides.

Das Anbringen der Klebeverschlüsse 20 in jeweils einer der vier Ecken ist exemplarisch in den Fig. 5a bis 5c gezeigt. In dem gezeigten Beispiel wird dabei ein Klebeverschluss 20 der in Fig. 3 gezeigten Variante in der in Fig. 4 links oben dargestellten Ecke der zugeschnittenen Schutzfolie 10 angebracht. Dies entspricht derjenigen Ecke, in deren Bereich die Tasche 15 zur Längskante 12 hin offen ist.The attachment of the adhesive closures 20 in each one of the four corners is exemplified in the Fig. 5a to 5c shown. In the example shown here is an adhesive closure 20 of in Fig. 3 shown variant in the in Fig. 4 attached top left corner of the cut protective film 10. This corresponds to that corner in the area of which the pocket 15 is open towards the longitudinal edge 12.

Der Klebeverschluss 20 wird zunächst mit einem der drei Klebebereiche 22 an dem umgeschlagenen Seitenbereich 18 der Schutzfolie 10 angebracht, so dass der angrenzende Faltbereich 24 entlang der Längskante 12 ausgerichtet ist. Anschließend wir der Klebeverschluss 20 entlang des Faltbereichs 24 gefaltet, wie durch Pfeil 44 schematisch dargestellt ist. Dadurch gelangt der nächste Klebebereich 22 auf der gegenüberliegenden Seite auf der Schutzfolie zur Anlage und wird dort angebracht, so dass die Tasche 15 an der Längskante 12 verschlossen wird.The adhesive closure 20 is first attached to the folded side region 18 of the protective film 10 with one of the three adhesive regions 22, so that the adjoining folding region 24 is aligned along the longitudinal edge 12. Subsequently, the adhesive closure 20 is folded along the fold region 24, as shown schematically by arrow 44. As a result, the next adhesive area 22 on the opposite side of the protective film comes to rest and is attached there, so that the pocket 15 is closed at the longitudinal edge 12.

Der dritte Klebebereich 22 steht dabei, wie in Fig. 5b gezeigt, seitlich über die Schutzfolie 10 bzw. die Tasche 15 hinaus und wird, angedeutet durch Pfeil 45, entlang des angrenzenden Faltbereichs 24 zurückgefaltet.The third adhesive area 22 stands, as in Fig. 5b shown laterally over the protective film 10 and the bag 15 and is, as indicated by arrow 45, folded back along the adjacent folding area 24.

Das Ergebnis ist dargestellt in Fig. 5c, wo der Klebeverschluss 20 bündig mit den Kanten der Schutzfolie 10 zum Abschluss kommt. Dadurch wird einerseits die Tasche 15 an der Längskante 12 verschlossen und andererseits ein verbesserter Eckenschutz an den besonders beanspruchten Ecken des Buches 30 bereitgestellt.The result is shown in Fig. 5c where the adhesive closure 20 comes flush with the edges of the protective film 10. As a result, on the one hand the pocket 15 is closed on the longitudinal edge 12 and on the other hand an improved corner protection is provided on the particularly stressed corners of the book 30.

Eine Schnittdarstellung entlang der Linie A-A durch die sich so ergebenden Schichten im Bereich der Ecke ist in Fig. 6 dargestellt.A sectional view along the line AA through the resulting layers in the region of the corner is in Fig. 6 shown.

Ein einfacher Klebeverschluss 20', wie in Fig. 3b dargestellt, wird entsprechend angebracht, wobei die beschriebene zweite Faltung entfällt.A simple adhesive closure 20 ', as in Fig. 3b is shown, is attached accordingly, with the described second convolution is eliminated.

In vergleichbarer Weise werden auch die offenen Seiten der Tasche 15' verschlossen. Schließlich kann, soweit das Schutzsystem 1 einen vierten Klebeverschluss 20 umfasst, auch noch die vierte Ecke, an der die Tasche 15 bereits fertigungsbedingt geschlossen ausgebildet ist, mit einem Klebeverschluss 20 als Eckenschutz versehen werden.In a similar way, the open sides of the pocket 15 'are closed. Finally, as far as the protective system 1 comprises a fourth adhesive seal 20, the fourth corner, on which the pocket 15 is already designed to be closed due to production, can also be provided with an adhesive closure 20 as corner protection.

Ohne Einschränkung des allgemeinen Erfindungsgedankens sind erfindungsgemäße Schutzsysteme 1 auch für Hefte, die in der Regel keinen Rücken 32 aufweisen, und für Ordner ohne eingebundene oder eingelegte Blätter 33 anwendbar.Without limiting the general inventive concept, protective systems 1 according to the invention are also applicable to booklets which generally have no spine 32 and to folders without bound or inserted sheets 33.
