Description

Die Erfindung bezieht sich auf einen Verschluss für aus einseitig kunststoffbeschichtetem Papier bestehende Versandtaschen, Briefumschläge o.dgl. mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a closure for mailing bags, envelopes or the like consisting of plastic coated paper on one side. with the features of the preamble of claim 1.

Es sind zum Beispiel aus der DE-A-30 21 989 Versandtaschen dieser Art mit einer Verschlussklappe bekannt, welche mittels zweier getrennter Klebverschlüsse zweimal nacheinander unter Bildung von Festverschlüssen auf der Rückwand festlegbar ist und die mit einem parallel zur Falzlinie verlaufenden, nach Bildung des ersten Verschlusses von der Klappe abtrennbaren Streifen ausgerüstet ist. Bei diesem bekannten Verschluss sind zwei Gummierungsstreifen vorhanden, die in zeitlichem Abstand nacheinander zunächst zur Bildung des ersten Verschlusses und zu einem späteren Zeitpunkt zur Bildung des zweiten Verschlusses zur Wirkung gebracht werden und dementsprechend getrennt voneinander angeordnet sind. Für die Herstellung des zweiten Festverschlusses muss der zweite Gummierungsstreifen ebenso aktiviert werden wie der erste Gummierungsstreifen für die Bildung des ersten Festverschlusses. Dies ist relativ arbeitsaufwendig und zeitraubend, wenn nach der amtlichen Postprüfung die Postsendung wieder verschlossen werden soll. Der Prüfbeamte muss sich zunächst überlegen, in welcher Weise er die Klebstoff-Aktivierung vornehmen muss. Falls es sich bei der Gummierung um Nassklebewerkstoff handelt, muss die Gummierung zunächst befeuchtet und nach dem Verkleben eine gewisse Abbindezeit berücksichtigt werden, ehe die Sendung in den normalen Postlauf zurückgegeben werden kann. Wenn die Gummierung ein mit Silikonpapierstreifen abgedeckter Selbstklebewerkstoff ist, muss zunächst diese Abdeckung ermittelt und abgezogen werden. Beide Arten von Handhabung erfordern zusätzliche Überlegungen und zusätzliche Arbeitszeit bzw. Arbeitsvorgänge. Falls im eiligen Postbetrieb dieser Aktivierungsvorgang für die zweite Festverklebung nicht sorgfältig vorgenommen wird, besteht die Gefahr, dass beim Wiederverschliessen einer solchen geprüften Postsendung kein ordentlicher Festverschluss zustande kommt.For example, from DE-A-30 21 989 mailing bags of this type with a closure flap are known, which can be fixed twice in succession by means of two separate adhesive closures with the formation of fixed closures on the rear wall, and which with a parallel to the fold line after the formation of the first Closure from the flap removable strips is equipped. In this known closure there are two rubber strips, which are brought into effect one after the other first to form the first closure and at a later time to form the second closure and are accordingly arranged separately from one another. For the production of the second fixed closure, the second rubber strip must be activated as well as the first rubber strip for the formation of the first fixed closure. This is relatively labor-intensive and time-consuming if the mail item is to be closed again after the official postal check. The inspector must first consider how to activate the adhesive. If the rubber coating is a wet adhesive material, the rubber coating must first be moistened and, after gluing, a certain setting time must be taken into account before the shipment can be returned to the normal post office. If the rubber coating is a self-adhesive material covered with silicone paper strips, this cover must first be determined and removed. Both types of handling require additional considerations and additional working time or work processes. If the activation process for the second permanent bond is not carried out carefully in a hurried postal operation, there is a risk that no proper permanent closure will occur when such a checked mail item is reclosed.

Diese Nachteile vermeidet der aus der DE-A-27 06 507 bekannte Verschluss für Versandtaschen dadurch, dass eine einzige Gummierung, die als Selbstklebeschicht vorhanden ist, sowohl für den ersten Festverschluss als auch für den zweiten Festverschluss dient. Diese eine Selbstklebeschicht, bei der es sich um eine Klebstoffpaarung handelt, wird bei der Bildung des ersten Festverschlusses aktiviert; eine Aktivierung nach erfolgter Postprüfung entfällt. Allerdings erfordert dieser bekannte Verschluss, was dessen Herstellung technisch relativ aufwendig macht, eine zusätzliche Schablone, die bei der Bildung des ersten Festverschlusses den aktivierten Klebstoffbelag partiell abdeckt, und das Öffnen des ersten Verschlusses muss relativ sorgfältig geschehen, andernfalls der abgedeckte Teil des Klebstoffbelags unerwünscht beschädigt werden kann, so dass wiederum die Gefahr besteht, dass nach erfolgter postalischer Prüfung bei der Bildung des zweiten Festverschlusses der erforderliche Klebekontakt nicht oder nicht ausreichend zustande kommt.The closure for mailing bags known from DE-A-27 06 507 avoids these disadvantages in that a single rubber coating, which is present as a self-adhesive layer, serves both for the first fixed closure and for the second fixed closure. This one self-adhesive layer, which is a pair of adhesives, is activated when the first fixed closure is formed; there is no activation after the postal check. However, this known closure, which makes its production relatively technically complex, requires an additional template which partially covers the activated adhesive coating when the first fixed closure is formed, and the opening of the first closure must be done relatively carefully, otherwise the covered part of the adhesive coating is undesirably damaged can, so that there is again the risk that, after the postal check has taken place, the required adhesive contact will not be made or will not be made sufficiently when the second fixed closure is formed.

Der Erfindung liegt die Aufgabe zugrunde, einen Verschluss der gattungsgemässen Art zu schaffen, der für den portogünstigen Drucksachenversand einen zwecks postalischer Prüfung einfach und leicht zu öffnenden ersten Festverschluss und nach erfolgter Prüfung ebenso einfach und leicht und ohne zusätzliche Hilfsmittel und/oder -massnahmen sicher schliessenden zweiten Festverschluss ergibt.The invention has for its object to provide a closure of the generic type which for postage-favorable printed matter dispatches a first fixed closure that is simple and easy to open for the purpose of postal checking and, after the check has been carried out, is also simple and easy and closes safely without additional aids and / or measures second fixed closure results.

Zur Lösung dieser Aufgabe sind bei der Erfindung die im kennzeichnenden Teil des Anspruchs 1 angegebenen Gestaltungsmerkmale vorgesehen, wobei noch in den Unteransprüchen 2 und 3 für die Aufgabenlösung zweckmässige und förderliche Ausbildungen beansprucht sind.To achieve this object, the design features specified in the characterizing part of claim 1 are provided in the invention, expedient and beneficial training for the solution of the task are still claimed in subclaims 2 and 3.

Mit der Erfindung wird ein problemlos zu handhabender Versandtaschenverschluss für aus beschichtetem Papier gefertigte Taschen, die insbesondere auch als leichtgewichtige Polstertaschen im Verkehr sind, zur Verfügung gestellt. Taschen mit diesem Verschluss sind einfach aufgebaut, lassen sich ohne zusätzliche maschinelle Einrichtungen auf den gebräuchlichen Versandtaschen-Fertigungsmaschinen herstellen und ohne Schwierigkeiten in automatischen Umschlagfüllmaschinen verwenden. Auf dem Postweg lassen sie sich in bekannter einfacher Weise zu Prüfzwecken öffnen und wieder sicher fest verschliessen.The invention provides an easy-to-handle mailing bag closure for bags made of coated paper, which are also in circulation as lightweight padded bags. Bags with this closure are simply constructed, can be produced on the usual mailing bag manufacturing machines without additional mechanical equipment and can be used in automatic envelope filling machines without difficulty. By post, they can be opened for testing purposes in a known, simple manner and securely closed again.

Die Erfindung ist nachfolgend anhand einer in der Zeichnung dargestellten Ausführungsform beispielsweise näher erläutert. Es zeigen:

  • Fig. 1 den Verschluss in betriebsfertigem Zustand vor der Bildung des ersten Festverschlusses,
  • Fig. 2 den Verschluss der Fig. 1 nach Bildung des ersten Festverschlusses in geschlossenem Zustand der Versandtasche,
  • Fig. 3 den Verschluss der Fig. 1 nach dem Öffnen des ersten Festverschlusses,
  • Fig. 4 den Verschluss der Fig. 1 in betriebsfertigem Zustand zur Bildung des zweiten Festverschlusses, und
  • Fig. 5 den Verschluss der Fig. 1 nach Bildung des zweiten Festverschlusses in geschlossenem Zustand der Versandtasche.
The invention is explained in more detail below using an embodiment shown in the drawing, for example. Show it:
  • 1 shows the closure in a ready-to-use state before the formation of the first fixed closure,
  • 2 the closure of FIG. 1 after formation of the first fixed closure in the closed state of the mailing bag,
  • 3 shows the closure of FIG. 1 after opening the first fixed closure,
  • Fig. 4 shows the closure of Fig. 1 in the operational state to form the second fixed closure, and
  • Fig. 5 shows the closure of Fig. 1 after formation of the second fixed closure in the closed state of the mailing bag.

In den Figuren 1 bis 5 ist eine Draufsicht auf die Rückwand einer in üblicher Weise aus einer Vorderwand und einer Rückwand 2 durch Randverschweissung an drei Seiten aus kunststoffbeschichtetem Papier gebildeten Versandtasche mit einer in ebenfalls üblicher Weise an der Vorderwand ansitzenden Verschlussklappe 3 veranschaulicht, wobei der untere Teil der Versandtasche jeweils fortgelassen ist.In Figures 1 to 5 is a plan view of the rear wall of a mailing bag formed in a conventional manner from a front wall and a rear wall 2 by edge welding on three sides of plastic-coated paper with a closure flap 3 also sitting on the front wall, the lower one Part of the mailing bag is omitted.

Die Verschlussklappe 3 ist um die Hauptfalzlinie 4 auf die Rückwand 2 der Tasche umlegbar. Parallel zur oberen Klappenkante 5 ist eine Zusatzfalzlinie 7 vorhanden, und der Endstreifen 6 zwischen der Klappenkante 5 und der Zusatzfalzlinie 7 ist doppellagig ausgebildet. Dabei sind die beiden Streifenteile 6a und 6b mit ihren beschichteten Flächenseiten gegeneinander gelegt, so dass die aussenliegenden Flächenseiten aus unbeschichtetem Papier bestehen. In Fig. 1 schaut der Betrachter demzufolge auf die aus unbeschichtetem Papier bestehende Aussenfläche des Streifenteils 6a, und in Fig. 2 auf die unbeschichtete Aussenfläche des Streifenteils 6b.The closure flap 3 can be folded around the main fold line 4 onto the rear wall 2 of the pocket. Parallel to the upper flap edge 5 is a closed Set fold line 7 is present, and the end strip 6 between the flap edge 5 and the additional fold line 7 is double-layered. The two strip parts 6a and 6b are laid with their coated surface sides against one another, so that the outer surface sides consist of uncoated paper. In FIG. 1, the viewer accordingly looks at the outer surface of the strip part 6a made of uncoated paper, and in FIG. 2 at the uncoated outer surface of the strip part 6b.

Ein Gummierungsstreifen 8 ist so auf der Verschlussklappe aufgebracht, dass er teilweise, im Bereich 8a, auf dieser unbeschichteten Flächenseite des Streifenteils 6a festsitzt und zum anderen Teil, im Bereich 8b, an der Innenfläche 9 der Verschlussklappe 3, angrenzend an die Zusatzfalzlinie 7, anhaftet.A rubber strip 8 is applied to the closure flap so that it partially sticks in the region 8a on this uncoated surface side of the strip part 6a and partly in region 8b adheres to the inner surface 9 of the closure flap 3, adjacent to the additional fold line 7 .

Es ist zweckmässig, dass dieser Gummierungsstreifen 8 aus einem selbstklebenden Klebewerkstoff besteht und bei der Lagerung und beim Versand mit einer abziehbaren Schutzabdeckung, wie silikoniertem Abdeckpapier, versehen wird. Man wird eine solche Schutzabdeckung vorteilhaft auch noch während der Füllung der Versandtaschen, insbesondere dann, wenn mit automatischen Umschlagfüllmaschinen gearbeitet wird, belassen, und erst dann, wenn die Versandtasche gefüllt ist, den Klebewerkstoff aktivieren. Zur Aktivierung genügt es, die (in der Zeichnung nicht dargestellte) Abdeckung einfach abzuziehen. Damit ist der Verschluss in den in Fig. 1 dargestellten betriebsbereiten Zustand gebracht. Zur Bildung des ersten Festverschlusses wird die Klappe 3 einfach um die Hauptfalzlinie 4 auf die Taschenrückwand 2 umgelegt und angedrückt. Da die Aussenfläche der Taschenrückwand 2 aus unbeschichtetem Papier besteht, haftet die Gummierung 8 über ihre ganze Breite fest an der Versandtaschenrückwand. Die so mittels des ersten Festverschlusses sicher verschlossene Versandtasche ist in Fig. 2 gezeigt.It is expedient that this rubber strip 8 consists of a self-adhesive material and is provided with a removable protective cover, such as siliconized cover paper, during storage and shipping. Such a protective cover will advantageously also be left in place while the mailing bags are being filled, in particular when working with automatic envelope filling machines, and only when the mailing bag is filled will the adhesive material be activated. To activate it, simply remove the cover (not shown in the drawing). The closure is thus brought into the operational state shown in FIG. 1. To form the first fixed closure, the flap 3 is simply folded over the main fold line 4 onto the pocket rear wall 2 and pressed on. Since the outer surface of the back wall 2 consists of uncoated paper, the gum 8 adheres firmly to the back wall of the mailing bag over its entire width. The shipping bag securely closed in this way by means of the first fixed closure is shown in FIG. 2.

Soll dieser erste Festverschluss geöffnet werden, zum Beispiel wenn die Sendung als «Drucksache» verschickt wird und eine postseitige Prüfung vorgesehen ist, so wird ein messerartiges Werkzeug, beispielsweise ein Brieföffner, nahe der Klappenkante 5 zwischen die Streifenteile 6a und 6b des doppellagigen Endstreifens 6 eingeführt und mit einem schräg nach unten gerichteten Druck horizontal entlang der Klappenkante 5 gezogen. Zur Erleichterung des Öffnungsvorgangs kann die Klappenkante 5 entsprechend perforiert sein.If this first fixed closure is to be opened, for example if the shipment is to be sent as a “printed matter” and a post-side check is provided, a knife-like tool, for example a letter opener, is inserted near the flap edge 5 between the strip parts 6a and 6b of the double-layer end strip 6 and pulled horizontally along the flap edge 5 with an obliquely downward pressure. The flap edge 5 can be perforated accordingly to facilitate the opening process.

Wenn die Streifenteile 6a und 6b in dieser Weise auseinander getrennt sind, wird die Verschlussklappe um die Hauptfalzlinie 4 nach oben in die Ebene der Vorderwand zurückgelegt. Der Verschluss hat dann die in Fig. 3 dargestellte Form. Auf der Aussenfläche der Versandtaschenrückwand 2 bleibt der abgetrennte Streifenteil 6a des Endstreifens 6 haften, während der Streifenteil 6b an der Verschlussklappe 3 verbleibt. Da die Haftkraft des Klebematerials an unbeschichtetem Papier wesentlich stärker ist als an beschichtetem Papier, löst sich beim Öffnen des ersten Festverschlusses in der zuvor beschriebenen Weise der Bereich 8b der Gummierung 8 von der beschichteten Innenfläche 9 der Verschlussklappe 3 ab und verbleibt auf der Rückwand 2, wie dies aus Fig. 3 zu ersehen ist.When the strip parts 6a and 6b are separated from one another in this way, the closure flap is returned upward about the main fold line 4 into the plane of the front wall. The closure then has the shape shown in FIG. 3. The separated strip part 6a of the end strip 6 adheres to the outer surface of the mailing bag rear wall 2, while the strip part 6b remains on the closure flap 3. Since the adhesive force of the adhesive material on uncoated paper is much stronger than on coated paper, when the first fixed closure is opened, the area 8b of the rubber coating 8 detaches from the coated inner surface 9 of the closure flap 3 and remains on the rear wall 2, as can be seen from Fig. 3.

Der Inhalt der Versandtasche ist nun frei zugängig und kann nach Belieben eingesehen und geprüft werden. Für das Wiederverschliessen genügt es, den an der Verschlussklappe verbliebenen Streifenteil 6b des Endstreifens 6 um die Zusatzfalzlinie 7 gegen die Innenfläche 9 der Verschlussklappe 3 umzulegen, so dass diese die in Fig. 4 veranschaulichte Form annimmt, und danach die Verschlussklappe 3 in dieser Form um die Hauptfalzlinie 4 gegen die Taschenrückwand 2 umzulegen und anzudrücken. Dabei kommt die aus unbeschichtetem Papier bestehende Aussenfläche des Streifenteils 6b gegen den Bereich 8b der Gummierung 8 zu liegen, und dann genügt ein einfaches Andrücken, um den zweiten Festverschluss herzustellen. Eine gesonderte Aktivierung der Gummierung ist nicht erforderlich, da der Klebewerkstoff nun mit der unbeschichteten Papierseite des Streifenteils 6b zusammenkommt, an dem er fest zu haften vermag. Der so gebildete zweite Festverschluss hat das in Fig. 5 gezeigte Aussehen.The contents of the mailing bag are now freely accessible and can be viewed and checked at will. For reclosing, it is sufficient to fold the strip part 6b of the end strip 6 remaining on the closure flap around the additional fold line 7 against the inner surface 9 of the closure flap 3, so that it takes on the shape illustrated in FIG. 4, and then the closure flap 3 in this shape fold the main fold line 4 against the pocket back wall 2 and press it on. The outer surface of the strip part 6b, which consists of uncoated paper, comes to lie against the area 8b of the rubber coating 8, and then a simple pressing is sufficient to produce the second fixed closure. A separate activation of the rubber coating is not necessary, since the adhesive material now comes together with the uncoated paper side of the strip part 6b, to which it can adhere firmly. The second fixed closure thus formed has the appearance shown in FIG. 5.

Hinweise für die Benutzungsart, zum Beispiel «Drucksache», «hier öffnen» oder sonstige Behandlungsanweisungen können auf der Aussenseite der Versandtaschenrückwand und/oder auf der Aussenseite der Verschlussklappe aufgedruckt oder sonstwie vermerkt werden. Ein Hinweis auf die durchgeführte postalische Prüfung kann auf der (nach der Bildung des ersten Festverschlusses innen gelegenen) Fläche des Streifenteils 6a des Endstreifens 6 angebracht werden. Dieser Hinweis erscheint nach Bildung des zweiten Festverschlusses dann auf der aussen gelegenen Fläche des auf der Rückwand 2 verbliebenen Streifenteils 6a.Information on the type of use, for example “printed matter”, “open here” or other treatment instructions can be printed on the outside of the back of the mailing bag and / or on the outside of the flap or otherwise noted. A reference to the postal check carried out can be provided on the surface of the strip part 6a of the end strip 6 (after the first fixed closure has been formed). After formation of the second fixed closure, this indication then appears on the outer surface of the strip part 6a remaining on the rear wall 2.

In abgewandelter Ausführungsform kann die Gummierung 8 an entsprechender Stelle auf der Versandtaschenrückwand 2 angebracht und bis zu Bildung des ersten Festverschlusses durch einen darauf aufgelegten Abdeckstreifen geschützt sein. Wiederum wird dann zur Aktivierung des Klebewerkstoffs der Abdeckstreifen abgezogen, und der erste Festverschluss wird dadurch gebildet, dass die Verschlussklappe 3 um die Hauptfalzlinie 4 auf die Rückwand 2 umgelegt wird. Es ergibt sich dann wiederum die in Fig. 2 dargestellte Form des Verschlusses, der wie zuvor beschrieben geöffnet und wieder verschlossen werden kann.In a modified embodiment, the rubber coating 8 can be attached at a corresponding point on the rear wall of the mailing bag 2 and can be protected by a cover strip placed thereon until the first fixed closure is formed. The cover strip is then again pulled off to activate the adhesive material, and the first fixed closure is formed by the closure flap 3 being folded over the main fold line 4 onto the rear wall 2. The result is again the shape of the closure shown in FIG. 2, which can be opened and closed again as described above.

In der in den Figuren 1 bis 5 dargestellten Ausführungsform der Erfindung hat die Verschlussklappe eine der Form der Tasche entsprechende rechteckige Form. Es können selbstverständlich die Ecken der Klappenkante auch abgerundet ausgebildet sein, was sich gegebenenfalls empfiehlt, wenn das Öffnen des ersten Festverschlusses erleichtert werden soll.In the embodiment of the invention shown in FIGS. 1 to 5, the closure flap has a rectangular shape corresponding to the shape of the pocket. Of course, the corners of the flap edge can also be rounded, which may be advisable if the opening of the first fixed closure is to be facilitated.
