Definitions
- the invention relates to an envelope with a cutting thread according to the preamble of claim 1.
- Envelopes with a cutting thread can be opened more easily, safely and with less damage to the contents than conventional envelopes.
- a thread is guided along an edge in the inside of the envelope and one end thereof is guided outwards.
- the user can open the envelope in a defined manner by pulling the thread sideways away from the envelope without using an additional tool.
- a bag for powdery materials which is made from a one-piece blank of paper.
- a flat tube is first formed by means of a wall section and two side tabs, on which a tear thread, which is partially coated with adhesive, is placed under tension in order to press the tube against a base.
- a bottom flap which was previously rubberized, is glued around the taut thread against the side flaps.
- the tear thread is cut off. In this way, it is outside the contents of the bag thus produced.
- the invention has for its object an envelope to be designed with a cutting thread so that the cutting thread can be attached in a simple manner during the production of the envelope.
- the cutting thread is positioned and fixed simultaneously with the production of the blank for the envelope or the envelope, by soaking or coating the cutting thread with adhesive. A slowing down of the production process is avoided.
- the additional outlay on equipment is minimal and easy to integrate into the existing production, since the thread is attached to the existing one Investment.
- the adhesive advantageously has sufficient elasticity after the thread has been introduced and hardened in order not to impair the normal behavior of an envelope.
- the insertion of a self-adhesive thread has the advantage in a known manner that the supplied thread can pass through an impregnation device before cutting.
- the thread can be fed in endlessly and cut to corresponding lengths, the length being able to proceed when the thread is already positioned. It then stays in place due to the adhesive effect and does not interfere with the subsequent folding of the flaps and further processing of the envelopes.
- the advantage is obtained that the cutting thread is held securely until it is finally folded and therefore does not fall out.
- it is inserted tightly, which is advantageous in the tearing process.
- the cutting thread is led out of the envelope on one side edge.
- it can be glued on the end. It can also be attached to a flat side near the end of the thread.
- This attachment is provided in the form of an adhesive dot or strip, for example a sticker or a solidified drop of an adhesive substance, which covers the preferably tightly lying thread.
- An adhesive strip can cover the entire length of the thread.
- Leading the thread out of the envelope makes it easier to grasp the thread. Fastening the thread section led out near the thread end enables the user to locate and grip the thread safely and secures the thread during transport.
- the way of attachment with the help of an adhesive dot or strip can also be used for advertising purposes, which inevitably draws the user's attention. This is reinforced by effective advertising design.
- the end opposite the led-out end can optionally also be led out or remain in the adhesive area of the side flap. In the latter case, deflection and leakage in the adhesive area are possible.
- Another embodiment provides for perforating the envelope at the cutting edge in order to support the cutting with the thread.
- the thread is formed in such a way that it is not raised than possible Folded edges of the envelope. This can be done by appropriate selection of a cutting thread material or by means of a band, the thickness of which is smaller than that of a folded edge and which is parallel to a cover surface with a broad side.
- FIG. 1 shows an envelope designed according to the invention from the back.
- An envelope la with an adhesive closure flap 2a has glued side flaps.
- a cutting thread 4a is inserted on the inside on a side edge. This has the advantage that the thread can be fed in the feed direction and then, if necessary, can be cut off after positioning above the blank. The insertion and setting of the thread can therefore take place in the course of the envelope production, without having to change anything in the basic process.
- the thread 4a is self-adhesive. It is therefore soaked in a supply roll when it is unrolled before it is positioned and cut off. The self-adhesive thread 4a therefore holds itself during the further assembly of the envelope la and moreover enables it to be securely fastened, which makes tearing open easier.
- the adhesive of the thread is chosen so that it does not become too hard and breaks after curing.
- the inserted thread 4a is very thin, so that it after tailoring the envelope does not lead to a raised edge in the area of the thread.
- the lead-out end of the thread is glued by a plate 6a made of paper or the like. It can be printed with advertising.
- the thread 4a is soaked or coated with a suitable adhesive, this self-adhesive property of the thread 4a already unfolding when it is inserted, so that the thread can be positioned in this way so that it can be further processed in the envelope maintains its position.
- the blanks for the production of the envelope 1a are shingled in a direction which runs transversely to the lower or upper edge.
- the short end section is gripped and with its help the stop 6a is detached from the envelope la.
- the stopping point 6a serves as a comfortable handle for the cutting thread and is brought away from the envelope into the plane of the envelope.
- a movement of the adhesive point including the cutting thread in a direction parallel to the cutting edge causes the letter to be cut open. Due to the anchoring of the cutting thread 4a to the end, the letter can be opened completely.
Abstract
Description
Die Erfindung bezieht sich auf einen Briefumschlag mit Aufschneidfaden nach dem Oberbegriff des Anspruchs 1.The invention relates to an envelope with a cutting thread according to the preamble of claim 1.
Briefumschläge mit Aufschneidfaden lassen sich leichter, gefahrloser und inhaltsschonender öffnen als herkömmliche Briefumschläge. Dazu wird im Inneren des Umschlages ein Faden an einer Kante entlanggeführt und eines seiner Enden nach außen geführt. Der Benutzer kann durch seitliches Ziehen des Fadens vom Umschlag weg den Umschlag definiert öffnen, ohne ein zusätzliches Werkzeug zu benutzen.Envelopes with a cutting thread can be opened more easily, safely and with less damage to the contents than conventional envelopes. For this purpose, a thread is guided along an edge in the inside of the envelope and one end thereof is guided outwards. The user can open the envelope in a defined manner by pulling the thread sideways away from the envelope without using an additional tool.
Aus US-A-1 385 493 ist ein Briefumschlag bekanntgeworden, bei dem ein Aufschneidfaden an der von der Verschlußlasche verschiedenen Falzkante des Briefumschlags durch Gummierung festlegbar ist. Ein Ende des Aufschneidfadens ist herausgeführt und mit einer Lasche verbunden, die von außen gegen den Umschlag festlegbar ist, beispielsweise ebenfalls durch Gummierung.From US-A-1 385 493 an envelope has become known in which a cutting thread can be fixed on the fold edge of the envelope which is different from the sealing flap by means of rubber coating. One end of the cutting thread is led out and connected to a tab, which can be fixed from the outside against the envelope, for example also by means of rubber.
Aus der US-A-2 956 727 ist ein Briefumschlag bekanntgeworden, bei dem nach einer ersten Alternative der an einer Falzkante angeordnete Aufreißfaden als flacher Streifen geformt ist, der in einem Endbereich durch Klebung festgelegt ist. Nach einer zweiten Alternative weist der Briefumschlag übereinstimmend mit dem Oberbegriff des Anspruchs 1 einen Aufschneidfaden auf, dessen gegenüberliegende seiten jeweils eine Schicht druckempfindlichen Klebstoffs aufweisen. Der Aufreißstreifen ist an einem Ende aus dem Umschlag herausgeführt und an der Außenseite durch Klebung festgelegt. Einen Flachstreifen als Aufreißfaden zu verwenden, ist im übrigen auch aus der US-A-2 954 916 bekanntgeworden.From US-A-2 956 727 an envelope has become known in which, according to a first alternative, the tear thread arranged on a folded edge is shaped as a flat strip, which is fixed in one end region by gluing. According to a second alternative, the envelope, in accordance with the preamble of claim 1, has a cutting thread, the opposite sides of which each have a layer of pressure-sensitive adhesive. The tear strip is led out of the envelope at one end and fixed on the outside by gluing. The use of a flat strip as a tear thread has also become known from US Pat. No. 2,954,916.
Aus der US-A-3 139 231 ist ein Aufreißfaden für einen Briefumschlag bekanntgeworden, dessen Ende über eine größere Strecke herausgeführt ist und an dem ein Siegel oder dergleichen befestigbar ist zur Fixierung des Fadens an der Außenseite des Umschlags. Der Anfreißfaden wird bspw. über mehrere Haltebereiche am Briefumschlag festgelegt. Das Siegel oder die Lasche, welche eine charakteristische Kontur erhält, ist so groß, daß auch eine Bedruckung möglich ist.From US-A-3 139 231 a tear thread for an envelope has become known, the end of which is led out over a longer distance and to which a seal or the like can be attached for fixing the thread on the outside of the envelope. The marking thread is fixed, for example, over several holding areas on the envelope. The seal or flap, which has a characteristic contour, is so large that printing is also possible.
Aus der US-A-1 821 011 ist ein Beutel für pulverförmige Stoffe bekanntgeworden, der aus einem einteiligen Zuschnitt aus Papier hergestellt wird. Mittels eines Wandabschnitts und zwei Seitenlaschen wird zunächst ein flacher Schlauch gebildet, auf den ein Aufreißfaden, der teilweise mit Klebstoff beschichtet ist, unter Spannung aufgelegt wird, um den Schlauch gegen eine Unterlage zu drücken. Anschließend wird eine Bodenlasche, die zuvor gummiert wurde, um den straff gespannten Faden gegen die Seitenlaschen geklebt. Danach wird der Aufreißfaden abgeschnitten. Er befindet sich auf diese Weise außerhalb des Inhalts des so hergestellten Beutels.From US-A-1 821 011 a bag for powdery materials has become known, which is made from a one-piece blank of paper. A flat tube is first formed by means of a wall section and two side tabs, on which a tear thread, which is partially coated with adhesive, is placed under tension in order to press the tube against a base. Then a bottom flap, which was previously rubberized, is glued around the taut thread against the side flaps. Then the tear thread is cut off. In this way, it is outside the contents of the bag thus produced.
Der Erfindung liegt die Aufgabe zugrunde, einen Briefumschlag mit einem Aufschneidfaden so zu gestalten, daß der Aufschneidfaden bei der Herstellung des Briefumschlages auf einfache Weise angebracht werden kann.The invention has for its object an envelope to be designed with a cutting thread so that the cutting thread can be attached in a simple manner during the production of the envelope.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.
Erfindungsgemäß erfolgt die Positionierung und Festlegung des Aufschneidfadens gleichzeitig mit der Herstellung des Zuschnitts für den Briefumschlag bzw. des Briefumschlags, indem der Aufschneidfaden mit Klebstoff getränkt oder beschichtet wird. Eine Verlangsamung des Produktionsablaufs wird dabei vermieden. Der zusätzliche Geräteaufwand ist minimal und leicht in die vorhandene Fertigung zu integrieren, da die Befestigung des Fadens in der bereits vorhandenen Anlage erfolgt. Der Klebstoff weist dabei in vorteilhafter Weise nach dem Einbringen des Fadens und Aushärten eine ausreichende Elastizität auf, um das übliche Verhalten eines Briefumschlags nicht zu beeinträchtigen. Das Einlegen eines selbstklebenden Fadens hat in bekannter Weise den Vorteil, daß der zugeführte Faden vor dem Abschneiden eine Tränkvorrichtung durchlaufen kann. Insbesondere, wenn der Faden so im Umschlag liegt, daß er bei der Fertigung der Umschläge in Vorschubrichtung zeigt, kann der Faden endlos zugeführt und auf entsprechende Längen geschnitten werden, wobei das Längen vor sich gehen kann, wenn der Faden bereits positioniert ist. Er hält sich dann durch die Klebwirkung an Ort und Stelle und beeinträchtigt das anschließende Falten der Laschen und Weiterverarbeiten der Umschläge nicht.According to the invention, the cutting thread is positioned and fixed simultaneously with the production of the blank for the envelope or the envelope, by soaking or coating the cutting thread with adhesive. A slowing down of the production process is avoided. The additional outlay on equipment is minimal and easy to integrate into the existing production, since the thread is attached to the existing one Investment. In this case, the adhesive advantageously has sufficient elasticity after the thread has been introduced and hardened in order not to impair the normal behavior of an envelope. The insertion of a self-adhesive thread has the advantage in a known manner that the supplied thread can pass through an impregnation device before cutting. In particular, if the thread lies in the envelope in such a way that it points in the feed direction during the manufacture of the envelopes, the thread can be fed in endlessly and cut to corresponding lengths, the length being able to proceed when the thread is already positioned. It then stays in place due to the adhesive effect and does not interfere with the subsequent folding of the flaps and further processing of the envelopes.
Ferner wird der Vorteil erhalten, daß der Aufschneidfaden bis zum endgültigen Falten sicher gehalten ist und daher nicht herausfällt. Außerdem ist er erfindungsgemäß straff eingelegt, was sich beim Aufreißvorgang vorteilhaft bemerkbar macht.Furthermore, the advantage is obtained that the cutting thread is held securely until it is finally folded and therefore does not fall out. In addition, according to the invention, it is inserted tightly, which is advantageous in the tearing process.
Der Verlauf des Aufschneidfadens im Bereich der Klebung der Seitenlaschen an beiden Enden der Aufschneidkante gewährleistet die ordnungsgemäße Lage des Aufschneidfadens vor dem Öffnen des Briefes, eine einwandfreie Übertragung der Aufreißkräfte während des Öffnens des Umschlags und ermöglicht ein vollständiges Öffnen der gesamten zugeordneten Kante des Umschlags.The course of the cutting thread in the area of the gluing of the side flaps at both ends of the cutting edge ensures the correct position of the cutting thread before opening the letter, a proper transmission of the tearing forces while opening the envelope and allows a complete opening of the entire associated edge of the envelope.
In einer vorteilhaften Ausgestaltung ist vorgesehen, den Aufschneidfaden an einer Seitenkante aus dem Umschlag herauszuführen. Er kann alternativ endseitig verklebt werden. Außerdem kann er auf einer Flachseite nahe dem Fadenende befestigt werden. Diese Befestigung ist in Form eines Klebepunktes oder -streifens etwa eines Aufklebers oder auch eines erstarrten Tropfens einer adhäsiven Substanz vorgesehen, der den vorzugsweise straff liegenden Faden abdeckt. Ein Klebestreifen kann den Faden auf seiner gesamten herausgeführten Länge abdecken. Das Herausführen des Fadens aus dem Umschlag erleichtert das Ergreifen des Fadens. Eine Befestigung des herausgeführten Fadenabschnitts nahe dem Fadenende ermöglicht dem Benutzer ein sicheres Auffinden und Ergreifen des Fadens und sichert den Faden beim Transport. Die Art und Weise der Befestigung mit Hilfe eines Klebepunktes oder -streifens kann auch zu Werbezwecken verwendet werden, der zwangsläufig die Aufmerksamkeit des Benutzers auf sich lenkt. Diese wird durch werbewirksame Gestaltung verstärkt.In an advantageous embodiment, it is provided that the cutting thread is led out of the envelope on one side edge. Alternatively, it can be glued on the end. It can also be attached to a flat side near the end of the thread. This attachment is provided in the form of an adhesive dot or strip, for example a sticker or a solidified drop of an adhesive substance, which covers the preferably tightly lying thread. An adhesive strip can cover the entire length of the thread. Leading the thread out of the envelope makes it easier to grasp the thread. Fastening the thread section led out near the thread end enables the user to locate and grip the thread safely and secures the thread during transport. The way of attachment with the help of an adhesive dot or strip can also be used for advertising purposes, which inevitably draws the user's attention. This is reinforced by effective advertising design.
Das dem herausgeführten Ende gegenüberliegende Ende kann wahlweise ebenfalls herausgeführt werden oder im Klebebereich der Seitenlasche verbleiben. Im letzteren Fall ist eine Umlenkung und ein Auslaufen im Klebebereich möglich. Eine weitere Ausgestaltung sieht vor, den Briefumschlag an der Aufschneidkante zu perforieren, um das Aufschneiden mit dem Faden zu unterstützen.The end opposite the led-out end can optionally also be led out or remain in the adhesive area of the side flap. In the latter case, deflection and leakage in the adhesive area are possible. Another embodiment provides for perforating the envelope at the cutting edge in order to support the cutting with the thread.
Erfindungsgemäß wird der Faden derart ausgebildet, daß er nicht erhabener ist als mögliche Falzkanten des Briefumschlages. Dies kann durch entsprechende Auswahl eines Schneidfadenmaterials geschehen oder mittels eines Bandes, dessen Dicke kleiner ist als die einer Falzkante und das mit einer Breitseite parallel zu einer Umschlagfläche liegt.According to the invention, the thread is formed in such a way that it is not raised than possible Folded edges of the envelope. This can be done by appropriate selection of a cutting thread material or by means of a band, the thickness of which is smaller than that of a folded edge and which is parallel to a cover surface with a broad side.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand einer Zeichnung erläutert.An embodiment of the invention is explained below with reference to a drawing.
Aus einzige Figur zeigt Figur 1 einen erfindungsgemäß ausgestalteten Briefumschlag von der Rückseite.From the single figure, FIG. 1 shows an envelope designed according to the invention from the back.
Ein Briefumschlag la mit einer Adhäsions-Verschlußlasche 2a weist verklebte Seitenlaschen auf. Ein Aufschneidfaden 4a ist innen an einer Seitenkante eingelegt. Dies hat den Vorteil, daß der Faden in Vorschubrichtung zugeführt werden kann, und dann gegebenenfalls nach der Positionierung oberhalb des Zuschnitts abgeschnitten werden kann. Das Einlegen und Festlegen des Fadens kann daher im Zuge der Umschlagfertigung erfolgen, ohne daß am prinzipiellen Ablauf etwas geändert werden muß. Der Faden 4a ist selbstklebend. Er wird daher beim Abrollen von einer Vorratsrolle getränkt, bevor er positioniert und abgeschnitten wird. Der selbstklebende Faden 4a hält sich daher bei der weiteren Konfektionierung des Umschlags la selbst und ermöglicht darüber hinaus ein sicheres Festlegen, wodurch das Aufreißen erleichtert wird.An envelope la with an
Der Klebstoff des Fadens ist derart gewählt, daß er nach dem Aushärten nicht zu hart wird und bricht.The adhesive of the thread is chosen so that it does not become too hard and breaks after curing.
Der eingelegte Faden 4a ist sehr dünn bemessen, so daß es nach dem Konfektionieren des Umschlags nicht zu einer erhabenen Kante im Bereich des Fadens führt.The inserted
Das herausgeführte Ende des Fadens wird durch ein Plättchen 6a aus Papier oder dergleichen verklebt. Es kann mit einer Werbebedruckung versehen werden.The lead-out end of the thread is glued by a plate 6a made of paper or the like. It can be printed with advertising.
Der Faden 4a ist mit einem geeigneten Klebstoff getränkt oder beschichtet, wobei diese selbstklebende Eigenschaft des Fadens 4a bereits beim Einlegen zur Entfaltung kommt, so daß der Faden auf diese Weise an Ort und Stelle positioniert werden kann, so daß er bei der weiteren Verarbeitung des Umschlags seine Lage beibehält. Bei der gezeigten Ausführungsform bewegen sich die Zuschnitte zur Herstellung des Umschlags la geschuppt in einer Richtung, die quer zur unteren bzw. oberen Kante verläuft.The
Zum Öffnen des Briefes wird der kurze Endabschnitt ergriffen und mit seiner Hilfe der Haltepunkt 6a vom Umschlag la abgelöst. Nun dient der Haltepunkt 6a als bequemer Griff des Aufschneidfadens und wird vom Umschlag weg in die Ebene des Umschlags gebracht. Eine Bewegung des Klebepunktes samt Aufschneidfaden in einer Richtung parallel zur Aufschneidkante bewirkt das Aufschneiden des Briefes. Aufgrund der Verankerung des Aufschneidfadens 4a bis zum Ende kann der Brief vollständig geöffnet werden.To open the letter, the short end section is gripped and with its help the stop 6a is detached from the envelope la. Now the stopping point 6a serves as a comfortable handle for the cutting thread and is brought away from the envelope into the plane of the envelope. A movement of the adhesive point including the cutting thread in a direction parallel to the cutting edge causes the letter to be cut open. Due to the anchoring of the
