Description

Die Erfindung betrifft einen Schnellhefter aus Karton mit einem ersten und einem zweiten Hefterdeckel, mit einer Hefteinrichtung mit Heftzungen und Lochstreifen, insbesondere für Schulgebrauch.The invention relates to a flat file from cardboard with a first and a second stapler cover, with a stapling device with tongues and perforated strips, in particular for school use.

Schnellhefter aus Karton sind bekannt; bei ihrer Herstellung wird der benötigte Kartonabschnitt von Band geschnitten, entsprechend der gewünschten Form gefalzt und geheftet; die für die Schnellhefter notwendige Hefteinrichtung mit Heftzungen und Lochstreifen werden schließlich in die vorgesehenen Löcher eingeführt. Diese Schnellhefter sind insbesondere für den Schulgebrauch zu aufwendig. Daneben gibt es Schnellhefter aus Kunststoff, bei denen sind ein (oftmals klare) erster Hefterdeckel als Vorderseite und eine mit der Hefteinrichtung versehener zweiter Hefterdeckel als Rückseite mittels eines Kunststoff-Streifens in Art eines Folien-Scharniers klappbar miteinander verbunden, wobei die Verbindung von Kunststoff-Streifen mit dem ersten Hefterdeckel einerseits und mit dem zweiten Hefterdeckel andererseits durch Schweißung erfolgt. Die Hefteinrichtung wird bei diesen Schnellheftern durch die Hefter-Rückseite geführt und von dem die beiden Heferdeckel der Vorder- und der Rückseite verbindenden Kunststoff-Streifen abgedeckt. Diese Schnellhefter zeichnen sich jedoch dadurch aus, daß sie wegen des Kunststoffes erhebliche Entsorgungsprobleme hervorrufen.Cardboard file folders are known; during its manufacture, the required section of cardboard is cut from tape, folded according to the desired shape and stapled; the stapling device with tongues and perforated strips required for the flat file is finally inserted into the holes provided. These flat files are too expensive, especially for school use. Besides There are plastic binders with a (often clear) first stapler cover as the front and a second stapler cover with the stapler as the back using a plastic strip in the manner of a foil hinge, whereby the connection of plastic strips with the first stapler cover on the one hand and with the second stapler cover on the other hand by welding. The stapling device is guided through the back of the stapler and covered by the plastic strips connecting the two stapler covers on the front and the back. However, these folder are characterized by the fact that they cause considerable disposal problems because of the plastic.

Hier setzt die Erfindung an, der die Aufgabe zu Grunde liegt, die Schnellhefter aus Karton so weiter zu bilden, daß sie weniger aufwendig sind und keine neuen Entsorgungsprobleme entstehen lassen.This is where the invention comes in, which is based on the object of further developing the cardboard file folders so that they are less complex and do not give rise to any new disposal problems.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die beiden Hefterdeckel mit einem biegsame Streifen aus Papier klappbar verbunden sind, wobei der biegsame Streifen in Längserstreckung zumindest nahe seinen seitlichen Begrenzungen mit einem Auftrag eines natürlichen Leimes oder Klebers versehen ist, mit dem die Verbindung zwischen dem Streifen und den Hefterdeckeln herstellbar ist. Alternativ ist die Lösung dadurch gegeben, daß die beiden Hefterdeckel mit einem biegsamen Streifen aus textilem Material klappbar verbunden sind, wobei der biegsame Streifen in Längserstreckung zumindest nahe seinen seitlichen Begrenzungen mit einem Auftrag eines natürlichen Leimes oder Klebers versehen ist, mit dem die Verbindung zwischen dem Streifen und den Hefterdeckeln herstellbar ist. Durch die Verwendung von Materialien, wie Pappe, Papier, textile Streifen und natürliche Leime bzw. Kleber wird ein Schnellhefter erhalten, der nicht nur einfach zu fertigen ist, sonderen der im Gebrauch praktisch und nach Verbrauch einfach zu entsorgen ist. Die Alternativ-Form nimmt dabei statt des Papiers einen biegsamen Streifen aus einem textilen Material, wobei vorteilhafterweise sowohl das Papier bzw. das textile Material des biegsamen Streifens zumindest weitgehend auf Naturfaserbasis aufgebaut ist. Die Verwendung von Materialien, die (nahezu) ausschließlich auf natürlicher Basis aufgebaut sind, vermeidet die Verwendung von Kunststoffen und stellt somit sicher, daß eine Verrottung eintritt, wenn der Schnellhefter -etwa geschreddert- auf eine Deponie gelangt. Mit diesen die beiden Deckel miteinander verbindenden biegsamen Streifen wird eine hinreichende Haltbarkeit für den Verwendungszweck erreicht.This object is achieved according to the invention in that the two stapler covers are hingedly connected with a flexible strip of paper, the flexible strip being provided with an application of a natural glue or adhesive with which the connection between the strip and the stapler cover can be produced. Alternatively, the solution is given in that the two stapler covers are hingedly connected with a flexible strip of textile material, the flexible strip being provided with an application of a natural glue or adhesive in the longitudinal extension, at least close to its lateral boundaries, with which the connection between the Strips and the stapler cover can be produced. Through the use of materials such as cardboard, paper, textile strips and natural glue or glue, a flat file is obtained which is not only easy to manufacture but also practical to use and easy to dispose of after use. The alternative form takes a flexible strip of a textile material instead of the paper, advantageously both the paper and the textile material of the flexible strip being at least largely based on natural fibers. The use of materials that are (almost) built entirely on a natural basis avoids the use of plastics and thus ensures that rotting occurs when the flat file - roughly shredded - reaches a landfill. With these flexible strips connecting the two lids, sufficient durability is achieved for the intended use.

Die Hefteinrichtung wird dabei mit dem einen der Hefterdeckel verbunden, beispielsweise dadurch, daß Einschnitte nahe dem dem biegsamen Streifen zugewandten Rand und symmetrisch zur Mitte vorgesehen ist, durch die die Heftzunge geführt wird. In einer vorteilhaften Weiterbildung weist der rückseitige der Hefterdeckel nahe dem dem biegsamen Streifen zugewandten Rand symmetrisch zur Mitte je einen Einschnitt auf, durch die die Heftzunge geführt ist. Bei dieser Ausbildungsform liegt die Heftzunge in ihrem Mittenbereich zwischen Hefterdeckel und dem auf diesen aufgeklebten Seitenstreifen und wird so verdeckt. In einer anderen vorteilhaften Weiterbildung weist der rückseitige der Hefterdeckel nahe dem dem biegsamen Streifen zugewandten Rand symmetrisch zur Mitte doppelte Einschnitte auf, durch die die Heftzunge geführt ist. Diese Einschnitte können sowohl als Einzel-Einschnitte als auch als Einschnitt-Paare vorgesehen sein. Während bei den ersteren die Heftzunge zwischen den beiden Einschnitten auf der Rückseite des Hefter-Deckels verläuft, verläuft bei den Einschnitt-Paaren jeweils nur der Teil der Hefterzunge rückseitig, der unter der von dem Einschnitts-Paar gebildeten Lasche liegt. Dabei ist die Breite des biegsamen Streifens derart vorgesehen, daß die durch einen der beiden Hefterdeckel geführten Teile der Heftzunge der Heftvorrichtung durch den Streifen abgedeckt ist. In beiden Fällen kann so die Heftzunge auch mit in die Verleimung einbezogen und so fixiert werden.The stapling device is connected to one of the stapler covers, for example in that incisions are provided near the edge facing the flexible strip and symmetrically to the center, through which the tongue is guided. In an advantageous development, the rear of the stapler cover near the edge facing the flexible strip has an incision symmetrical to the center through which the stitching tongue is guided. In this form of training, the stitching tongue lies in its central area between the stapler cover and the side strip glued to it and is thus covered. In another advantageous development, the rear of the stapler cover near the edge facing the flexible strip has double incisions symmetrically to the center through which the tongue is guided. These incisions can be provided both as individual incisions and as pairs of incisions. While in the former the stitching tongue runs between the two incisions on the back of the stapler cover, in the case of the incision pairs only the part of the stitching tongue runs on the back, which lies under the flap formed by the incision pair. The width of the flexible strip is provided in such a way that the parts of the tongue of the stapling device guided through one of the two stapler covers are covered by the strip. In both cases, the tongue can also be used in the gluing be included and thus fixed.

Vorteilhaft ist es, wenn die Heftzunge mit symmetrisch zur Mitte angeordneten, den Einschnitten vorgelagerten Verbreiterungen versehen ist, wobei deren Breite die Einschnitt-Breite übersteigt und so eine Fixierung der Heftzunge bewirkt. Diese als ein- oder beidseits überstehende Nasen ausgebildeten Verbreiterungen sind derart angeordnet, daß sie ein Durchschieben durch die Einschnitte sperren. Beide Ausführungsformen dieses Schnellhefters lassen sich in einfacher Weise auch als Massenprodukt herstellen und auch dementsprechend entsorgen.It is advantageous if the stitching tongue is provided with widenings arranged symmetrically to the center, upstream of the incisions, the width of which exceeds the incision width and thus fixes the stitching tongue. These extensions, which are designed as projections projecting on one or both sides, are arranged in such a way that they prevent them from being pushed through the incisions. Both embodiments of this folder can also be easily mass-produced and disposed of accordingly.

Darüber hinaus wird vorgeschlagen, daß der Leim für den Leimauftrag auf dem biegsamen Streifen und/oder den korrespondierenden Randbereichen der Hefterdeckel ein natürlicher Leim, beispielsweise auf Zellulose- oder Ligninbasis, ist. Alternativ dazu wird vorgeschlagen, daß der Leim für den Leimauftrag auf dem biegsamen Streifen und/oder auf den korrespondierenden Randbereichen der Hefterdeckel ein unter Temperatureinwirkung aufschmelzbarer Leim, beipielsweise auf Basis eines natürlichen Harzes, ist. Mit dieser Auswahl der Leime und Kleber wird eine Fertigungsmöglichkeit erreicht, die in vorhandenen Fertigungsgegebenheiten realisierbar ist, wobei besondere unter Temperatureinwirkung aufschmelzbare oder abbindende Leime bzw. Kleber den für eine Massenfertigung einzuhaltenden Bedingungen gerecht werden. Dabei können insbesondere die Fertigungseinrichtungen für Kunststoff-Schnellhefter weiterhin für die Herstellung eines aus Karton bestehenden und somit umweltfreundlich zu entsorgenden Schnellhefters benutzt werden, was eine einfache Umstellung der Produktion erlaubt.In addition, it is proposed that the glue for the glue application on the flexible strip and / or the corresponding edge areas of the stapler cover is a natural glue, for example based on cellulose or lignin. As an alternative to this, it is proposed that the glue for the glue application on the flexible strip and / or on the corresponding edge regions of the stapler cover is a glue that melts under the influence of temperature, for example based on a natural resin. With this selection of the glues and adhesives, a manufacturing possibility is achieved that can be realized in existing manufacturing conditions, whereby particularly glues or adhesives that melt or set under the influence of temperature meet the conditions to be met for mass production. In particular, the manufacturing facilities for plastic flat file can still be used for the production of a flat file made of cardboard and thus to be disposed of in an environmentally friendly manner, which allows easy conversion of production.

In einer bevorzugten Ausführungsform ist vorzugsweise der die Hefter-Rückseite bildende Hefterdeckel mit einer Tasche, gebildet von einem Taschenstreifen, versehen, wobei dessen Höhenerstreckung gleich der Höhe und dessen Breitenerstreckung gleich höchstens 2/3, vorzugsweise 1/4 der Breite der Hefterdeckel ist, und wobei der obere, der äußere und der untere Randbereich des Taschenstreifens und/oder die diesen Randbereichen zugeordneten Ränder des Hefterdeckels mit einem streifenförmigen Leim- bzw. Kleberauftrag zum Verbinden von Taschenstreifen und Hefterdeckel versehen sind. Durch diesen aufgelegten und in den Randbereichen festgelegten Taschenstreifen wird der Schnellhefter mit einer Aufbewahrungstasche für einzelne Blätter geschaffen, die in einfacher Weise gebildet ist, und so eine wirtschaftliche Fertigung erlaubt.In a preferred embodiment, the stapler cover forming the back of the stapler is preferably provided with a pocket formed by a pocket strip, the extent of which extends is equal to the height and its width extension is at most 2/3, preferably 1/4 the width of the stapler cover, and the upper, the outer and the lower edge region of the pocket strip and / or the edges of the stapler cover assigned to these edge regions with a strip-shaped glue or adhesive application for connecting pocket strips and stapler cover. By means of this pocket strip placed on and fixed in the edge areas, the flat file is created with a storage pocket for individual sheets, which is formed in a simple manner, and thus allows economical production.

Zur wirtschaftlichen Herstellung wird vorteilhaft ein Herstellungsverfahren benutzt, mit dem an sich Kunststoff-Schnellhefter hergestellt werden. In das Herstellungsverfahren wird eine Möglichkeit zum Leimauftrag eingeschaltet, wobei über geheizte Übertragungswalzen ein schmelzbarer Naturkleber, etwa Kollophonium, als Leimstreifen auf die Hefterdeckel und/oder den biegsamen Streifen aus textitem Material übertragen, der sofort abgekühlt und damit erstarrt, wodurch sowohl die Hefterdeckel als auch der biegsame Streifen problemlos in Herstellungsgang weiter bewegt werden können. In den Stationen der Herstellungsvorrichtung, in denen die Hefterdeckel aus Kunststoff verschweißt werden, wird hier der so aufgetragene Kleber aktiviert und die Verbindung zwischen dem biegsamen Streifen und den beiden zugeordneten Randbereichen der beiden Hefterdeckel hergestellt. Mit dieser einfachen Umstellung lassen sich die lediglich aus in einfacher Weise entsorgbaren Materialien bestehenden Schnellhefter mit den bekannten Vorrichtungen zur Herstellung der schwer entsorgbaren Schnellhefter aus Kunststoff wirtschaftlich fertigen, wobei es sichz von selbst versteht, daß der Auftrag des Kleberstreifens nicht notwendig im Zuge der Herstellung erfolgen muß; so kann beispeilsweise der biegsame Streifen aus textilem Material mit einem derartigen Auftrag versehen sein, so daß eine Kleberauftragsstation im Zuge der Herstellungsvorrichtung entfallen kann.For economical production, a production process is advantageously used with which plastic flat files are produced per se. In the manufacturing process, a possibility for glue application is switched on, whereby a fusible natural adhesive, such as rosin, is transferred as a glue strip to the stapler cover and / or the flexible strip of textile material via heated transfer rollers, which immediately cools and thus solidifies, causing both the stapler cover and the flexible strip can be easily moved in the manufacturing process. In the stations of the production device in which the plastic stapler covers are welded, the adhesive applied in this way is activated and the connection between the flexible strip and the two associated edge regions of the two stapler covers is established. With this simple changeover, the flat file, which consists only of easily disposable materials, can be economically manufactured with the known devices for producing the hard-to-dispose flat file made of plastic, it being understood that the application of the adhesive strip is not necessary in the course of production got to; for example, the flexible strip of textile material can be provided with such an application, so that an adhesive application station in the course of the manufacturing device can be dispensed with.

Der in seinem unteren Teil aufgeschlagene Schnellhefter besteht aus dem oberen Hefterdeckel 1 und dem unteren Hefterdeckel 2. Diese beiden im wesentlichen gleichformatigen Deckel sind mittels eines biegsamen Streifens 3 verbunden, wobei beidseits der Längsränder dieses Streifens 3 Leim- oder Kleberaufträge vorgesehen sind, mit deren Hilfe die Verbindung der Hefterdeckel 1 und 2 und der zugeordneten Randbereiche des biegsamen Streifens 3 erfolgen kann. Zwischen den beiden (nicht näher bezeichneten) Randbereichen mit den Leim- oder Kleberaufträgen befindet sich ein den Rücken des Schnellhefters bildender Mittelstreifen 3.1, der frei von einem Leim- oder Kleberauftrag gehalten ist. Der untere Hefterdeckel 2 ist mit der Hefteinrichtung versehen, die nahe dem dem biegsamen Streifen zugeordneten Rand dieses unteren Hefterdeckels 2 angeordnet ist. Dieser besteht aus einem Streifen mit beidseits überstehender Heftzunge 6 und der mit den im Abstand üblicher Locher vorgesehenen Löchern 7.1 Heftlasche 7. Die aufzubewahrenden Papiere, die mit einer im Lochabstand der Heftlasche 7 befindlichen Lochung versehen sind, können mit den aufgebogenen überstehenden Enden der Heftzunge 6 gefaßt und festgelegt werden, wobei die Enden der Heftzunge in üblicher Weise nach dem Aufsetzen der Heftlasche 7 umgelegt werden.The open file in its lower part consists of the upper stapler cover 1 and the lower stapler cover 2. These two essentially identical covers are connected by means of a flexible strip 3, 3 glue or adhesive applications being provided on both sides of the longitudinal edges of this strip, with the aid of which the connection of the stapler cover 1 and 2 and the associated edge areas of the flexible strip 3 can be made. Between the two (not specified) edge areas with the glue or glue application is a central strip 3.1 forming the back of the flat file, which is kept free of glue or glue application. The lower stapler cover 2 is provided with the stapling device which is arranged near the edge of this lower stapler cover 2 assigned to the flexible strip. This consists of a strip with the tongue 6 protruding on both sides and the hole 7.1 with the holes 7.1 which are provided at a distance from the usual holes. The paper to be kept, which is provided with a hole in the hole distance of the tongue 7, can be bent with the bent ends of the tongue 6 are grasped and fixed, the ends of the tongue being folded in the usual way after the attachment of the tab 7.

In einer Weiterbildung ist der untere Hefterdeckel 2 mit einer Tasche etwa zur Aufnahme einzelner loser Blätter versehen, die gebildet ist von einem Taschenstreifen 4, der an seinem oberen, äußeren und unteren Rändern mit einem Leim- oder Kleberauftrag 5 versehen ist. Dieser Taschenstreifen wird vorteilhaft aus dem gleichen Karton oder aus einem (festeren) Papier gebildet. Es versteht sich von selbst, daß dieser Leim- oder Kleberauftrag auch auf den entsprechenden Randbereichen des unteren Hefterdeckels 2 oder auch sowohl auf dem Taschenstreifen 4 als auch auf dem Hefterdeckel 2 vorgesehen sein können. Mit diesem Leim- oder Kleberauftrag 5 wird der Taschenstreifen 4 an dem Hefterdeckel 2 befestigt, wobei vorteilhaft der gleiche Leim- bzw. Kleber eingesetzt wird, wie zum Verbinden der Hefterdeckel 1 und 2 mit dem biegsamen Streifen 3. Dabei ist der Taschenstreifen 4 in seiner Höhenerstreckung gleich der Höhe der Hefterdeckel 2 bzw. auch 1. Die Breite des Taschenstreifens ist dagegen geringer; um lose Blätter o.dgl. einfach in die Taschen einschieben und dort sicher halten zu können, wird die Breite des Taschenstreifens 4 geringer als 2/3 der Breite der Hefterdeckel 2 bzw. 1 gehalten (eine günstige Breite liegt bei 1/4 der Breite der Hefterdeckel).In a further development, the lower stapler cover 2 is provided with a pocket, for example for receiving individual loose sheets, which is formed by a pocket strip 4, which is on its upper, outer and the lower edges are provided with a glue or glue application 5. This pocket strip is advantageously formed from the same cardboard or from a (firmer) paper. It goes without saying that this glue or adhesive application can also be provided on the corresponding edge areas of the lower stapler cover 2 or both on the pocket strip 4 and on the stapler cover 2. With this glue or adhesive application 5, the pocket strip 4 is fastened to the stapler cover 2, the same glue or adhesive advantageously being used as for connecting the stapler covers 1 and 2 with the flexible strip 3. The pocket strip 4 is in its Extent of height equal to the height of the stapler cover 2 or 1. The width of the pocket strip, however, is smaller; for loose leaves or the like Simply insert it into the pockets and hold it securely, the width of the pocket strip 4 is kept less than 2/3 of the width of the stapler cover 2 or 1 (a favorable width is 1/4 the width of the stapler cover).

Die Figur 2a zeigt eine einfache Anbringung der Heftzunge 6: Beidseits der Symmetrielinie weist der Hefterdeckel 2 nahe dem biegsamen Streifen 3 Einschnitte 2.1 auf, durch die Heftzunge 6 von der Rückseite her eingeführt ist. Die Heftzunge 6 selbst ist mit Verbreiterungen 6.1 versehen, die bei eingeführter Heftzunge 6 nahe diesen Einschnitten 2.1 liegen und so ein Verschieben der eingeführten Heftzunge 6 verhindern. Die Figur 2b zeigt eine andere Möglichkeit des Anbringens der Hefteinrichtung in dem Hefterdeckel 2, der beidseits der Symmetrielinie mit zwei parallelen Einschnitten 2.2 versehen ist, durch den die Heftzunge 6 so geführt ist, daß sie im wesentlichen auf der Innenseite des Hefterdeckels 2 verläuft. Die Heftzunge 6 ist dabei durch die Einschnitte festgelegt, der Lochstreifen erlaubt in bekannter Weise das Fixieren der abzuheftenden Blätter.FIG. 2a shows a simple attachment of the staple tongue 6: on both sides of the line of symmetry, the stapler cover 2, near the flexible strip 3, has incisions 2.1, through which the staple tongue 6 is inserted from the rear. The tongue 6 itself is provided with widenings 6.1 which, when the tongue 6 is inserted, are close to these incisions 2.1 and thus prevent the inserted tongue 6 from moving. FIG. 2b shows another possibility of attaching the stapling device in the stapler cover 2, which is provided on both sides of the line of symmetry with two parallel incisions 2.2 through which the stapling tongue 6 is guided so that it runs essentially on the inside of the stapler cover 2. The tongue 6 is determined by the incisions, the punched tape allows fixing the sheets to be stapled in a known manner.
