Abstract

The envelope has two parallel fold grooves (10,11) for folding the flap (4). The back (9) of the envelope and the fold grooves are formed and positioned so that the closure flap, when folded along the first groove (10) rests on the inner surface of the front (8) of the envelope beside the back of the envelope. The part (15) of the flap covered with an adhesive layer (14) is coated with a separating agent (16). The closure flap when folded over the second fold-groove (11) rests with the entire layer of adhesive on the outside of the back of the envelope to which it sticks.

Description

Die vorliegende Erfindung betrifft ein rechteckiges, aus einem im wesentlichen rechteckigen Stänzling gebildetes Kuvert. Bis jetzt war die Fachwelt der Meinung, man sei im Verlauf der Entwicklung zu einem nicht mehr zu verbessernden Resultat gelangt. Bei der Suche nach weiteren Einsparungsmöglichkeiten, die sich auf die Herstellung und den Vertrieb auswirken, konnte mit einer verhältnismässig geringen Änderung gegenüber den bekannten Kuverts erreicht werden, dass sich einerseits bei der Herstellung Material und andererseits beim Transport und der Lagerung Platz ersparen liess. Das Kuvert der eingangs genannten Art, dass diese beiden Bedingungen erfüllt, ist dadurch gekennzeichnet,

  • dass der Stänzling (1) zwei vollständig gerade, zu einander parallele seitliche Begrenzungskanten (2, 3) aufweist, sodass er aus einer geraden Papierbahn konstanter Breite nur durch Abschneiden, jedoch ohne zusätzliche seitliche Formgebung herstellbar ist, und
  • dass beim Stänzling die den wesentlichen Teil des freien Randes der Verschlussklappe (4) zu bilden bestimmte Schnittkante (5) komplementär zur gegenüberliegenden Schnittkante (6) verläuft, welch letztere die die Einfüllöffnung des Kuverts zu begrenzen bestimmte Kante ist, sodass beim Abschneiden eines Stänzlings von der Papierbahn kein Abfall entsteht.
The present invention relates to a rectangular envelope formed from an essentially rectangular diecut. Up until now, experts believed that the result of the development could not be improved. When looking for further savings that affect production and sales, a relatively small change compared to the known envelopes made it possible to save space on the one hand in the manufacture of material and on the other hand in transport and storage. The envelope of the type mentioned at the beginning, which fulfills these two conditions, is characterized in that
  • that the diecut (1) has two completely straight lateral boundary edges (2, 3) which are parallel to one another, so that it can be produced from a straight paper web of constant width only by cutting, but without additional lateral shaping, and
  • that the cut edge (5) to form the essential part of the free edge of the closure flap (5) of the diecut is complementary to the opposite cut edge (6), the latter being the certain edge to limit the fill opening of the envelope, so that when cutting off a diecut from there is no waste on the paper web.

Bei der Herstellung solcher Kuverts wird also einerseits Rohmaterial, also Papier eingespart und, was heute ebenso wichtig ist, es wird das Entstehen von Abfall vermieden, wodurch sich die heute üblichen Kosten für die Entsorgung dieses Abfalls einsparen lassen. Bei einem besonders zweckmässigen Verfahren zur Herstellung von Stänzlingen der vorgenannten Art werden aus einer geraden Papierbahn durch Abschneiden und anschliessendes Trennen in der Bahnlängsrichtung zwei oder mehr nebeneinanderliegende Stänzlinge erzeugt.In the production of such envelopes, raw material, i.e. paper, is saved on the one hand and, which is just as important today, the generation of waste is avoided, as a result of which the usual costs for the disposal of this waste can be saved. In a particularly expedient method for producing die cuts of the aforementioned type, two or more adjacent die cuts are produced from a straight paper web by cutting and subsequent separation in the longitudinal direction of the web.

Zusätzlich lässt sich ein derartiges Kuvert noch dadurch verbessern, dass man es mit einem Selbstklebeverschluss versieht, bei welchem nur ein Teil der Verschlussklappe mit einer Haftkleberschicht versehen ist. Bei der Herstellung von Kuverts mit Selbstklebeverschluss wird die Haftkleberschicht durch einen mit einem Trennmittel beschichteten Abdeckstreifen abgedeckt, der vor dem Zukleben des Kuverts entfernt werden muss. Es ist an sich bekannt, dass diese Streifen mindestens zwei Nachteile aufweisen: einerseits kosten sie bei der Herstellung und beim Aufbringen Geld und andererseits muss der Benützer des Kuverts den Streifen entsorgen, was ihm je nach den Umständen mehr oder weniger Mühe macht. Bei einer speziellen Ausführungsform eines Kuverts nach der vorliegenden Erfindung werden nun diese beiden Nachteile dadurch vermieden, dass es zwei zum Umklappen der Verschlussklappe dienende, zueinander parallele Falzrillen aufweist, wobei die Kuvertrückseite so ausgebildet ist und die Falzrillen so angeordnet sind, dass die Verschlussklappe dann, wenn sie um die erste Falzrille umgelegt ist, neben der Kuvertrückseite auf der Innenfläche der Kuvertvorderseite aufliegt, die dort, wo der Haftklebestreifen aufliegt, mit einem Trennmittel beschichtet ist, während die Verschlussklappe dann, wenn sie um die zweite Falzrille umgelegt ist, mit dem ganzen Haftklebestreifen auf der Aussenseite der Kuvertrückseite aufliegt und dort haftet.In addition, such an envelope can be improved further by providing it with a self-adhesive closure in which only part of the closure flap is provided with a layer of pressure-sensitive adhesive. When producing envelopes with a self-adhesive seal, the pressure-sensitive adhesive layer is covered by a cover strip coated with a release agent, which must be removed before the envelope is sealed. It is known per se that these strips have at least two disadvantages: on the one hand they cost money to produce and apply and on the other hand the user of the envelope has to dispose of the strip, which is more or less difficult depending on the circumstances. In a special embodiment of an envelope according to the present invention, these two disadvantages are now avoided in that it has two fold grooves which serve to fold the closure flap and are parallel to one another, the rear side of the envelope being designed and the fold grooves being arranged such that the closure flap then, if it is wrapped around the first fold, lies next to the back of the envelope on the inner surface of the front of the envelope, which is coated with a release agent where the pressure-sensitive adhesive tape rests, while, when it is wrapped around the second fold, with the whole Adhesive tape lies on the outside of the back of the envelope and adheres there.

Nachfolgend werden anhand der beiliegenden Zeichnung erfindungsgemässe Ausführungsbeispiele beschrieben. In der Zeichnung zeigt

  • die Fig. 1 einen Stänzling, bevor er zum Kuvert gefaltet ist, und
  • die Fig. 2 einen Doppelstänzling, bevor er in die beiden Teile getrennt ist.
Exemplary embodiments according to the invention are described below with reference to the accompanying drawing. In the drawing shows
  • 1 shows a die cut before it is folded into an envelope, and
  • Fig. 2 shows a double cutting before it is separated into two parts.

Der in der Fig. 1 dargestellte, als Ganzes mit 1 bezeichnete Stänzling wurde aus einer Papierbahn konstanter Breite nur durch Abschneiden, jedoch ohne seitliche Formgebung herausgeschnitten. Er weist daher zwei vollständig gerade, zueinander parallele seitliche Begrenzungskanten 2 und 3 auf. Die den wesentlichen Teil des freien Randes der Verschlussklappe 4 zu bilden bestimmte Schnittkante 5 verläuft komplementär zur gegenüberliegenden Schnittkante 6, bei welcher es sich um die die Einfüllöffnung des Kuverts zu begrenzen bestimmte Kante handelt. Durch diese Formgebung besteht keine Möglichkeit für das Entstehen von Abfall. Damit aus einem Stänzling ein Kuvert gefertigt werden kann, braucht es üblicherweise noch einige Arbeitsschritte, nämlich das Anbringen von Falzrillen und das Auftragen einer Haftkleberschicht: Das erfindungsgemässe Kuvert benötigt drei Falzrillen, nämlich die Falzrille 7, die die Kuvertvorderseite 8 von der Kuvertrückseite 9 abgrenzt, und die beiden Falzrillen 10 und 11, wobei die Falzrille 10 dazu dient, beim geöffneten Kuvert die Verschlussklappe 4 von der Kuvertvorderseite 8, auf deren Innenfläche sie aufliegt, abzugrenzen, während beim Verschliessen des Kuverts die Verschlussklappe 4 um die Falzrille 11 gefalten wird, damit sie aussen auf die Kuvertrückseite 9 zu liegen kommt. In einem weiteren Bearbeitungsschritt wird der Klebstoff aufgetragen: Zur dauerhaften Verbindung der Vorderseite 8 mit der Rückseite 9 dienen die beiden Kleber-Streifen 12 und 13, von denen je einer in der an den seitlichen Begrenzungskanten 2 bzw. 3 angrenzenden Zone angebracht ist. Zum Verschliessen des Kuverts dient die an der Verschlussklappe 4 angebrachte Haftkleberschicht 14. Zusätzlich zu dieser Haftkleberschicht 14 besitzt der Stänzling auf der Innenfläche der Vorderseite ein Gebiet 15, das mit einem Trennmittel 16 beschichtet ist. Bei der Fabrikation eines erfindungsgemässen Kuverts wird nun wie folgt vorgegangen:The die cut shown as a whole in FIG. 1 was cut out of a paper web of constant width only by cutting, but without any lateral shaping. It therefore has two completely straight, parallel boundary edges 2 and 3. The cut edge 5 which forms the essential part of the free edge of the closure flap 4 runs complementarily to the opposite cut edge 6, which is the edge which is certain to limit the fill opening of the envelope. This shape means there is no possibility of waste being generated. In order for an envelope to be produced from a die-cut, a few further steps are usually required, namely the application of fold grooves and the application of a layer of pressure-sensitive adhesive: The envelope according to the invention requires three fold grooves, namely the fold groove 7, which delimits the front side 8 of the envelope from the rear side 9 of the envelope. and the two fold grooves 10 and 11, the fold groove 10 serving to separate the closure flap 4 from the envelope front side 8, on the inner surface of which it rests, when the envelope is open, while the closure flap 4 is folded around the fold groove 11 when the envelope is closed it comes to rest on the back of the envelope 9. In a further processing step, the adhesive is applied: the two adhesive strips 12 and 13, one in each of which is used for the permanent connection of the front 8 with the rear 9, are used lateral boundary edges 2 or 3 adjacent zone is attached. The pressure-sensitive adhesive layer 14 attached to the closure flap 4 serves to close the envelope. In addition to this pressure-sensitive adhesive layer 14, the diecut has an area 15 on the inner surface of the front side which is coated with a release agent 16. The procedure for producing an envelope according to the invention is now as follows:

Falls das Kuvert innen oder aussen oder auf beiden Seiten bedruckt werden muss, wird die von einer Papierrolle in konstanter Breite abgezogene Papierbahn wunschgemäss, also nach Bedarf, periodisch bedruckt, also so, dass der Abstand zwischen den Anfängen der sich wiederholenden Druckflächen mit der Länge des Stänzlings übereinstimmt. Dann wird an den Stellen 15 das Trennmittel 16 angebracht. Nachher werden, falls es sich um Fensterkuverts handelt, die Fensteröffnungen ausgeschnitten und mit durchsichtigem Material wieder verschlossen, wie das an sich bekannt ist. Anschliessend werden die als Falzrillen dienenden Quer-Rillen 7, 10 und 11 angebracht. Nachher erfolgt der Trennschnitt, durch welchen die Stänzlinge ohne die Bildung von Abfallstücken voneinander abgetrennt werden und die Schnittkanten 5 und 6 entstehen. Wie man aus der Zeichnung ersehen kann, verläuft die Schnittkante an jedem ihrer beiden Enden auf eine Länge von ca. 8 mm senkrecht zur seitlichen Begrenzungskante 2 bzw. 3. Anschliessend weist sie einen im stumpfen Winkel weiter führenden Abschnitt auf, während sie auf dem wesentlichen Teil ihrer Länge senkrecht zu den seitlichen Begrenzungskanten 2/3 verläuft. Auf die einzelnen Stänzlinge werden daraufhin die Kleber-Streifen 12 und 13 aufgebracht und es wird die Kuvertrückseite 9 um die Falzrille 7 gefalzt und auf die Vorderseite gedrückt, wo sie durch die beiden Kleber-Streifen 12 und 13 festgehalten wird. Nun wird auf der Verschlussklappe 4 die Haftkleberschicht 14 aufgetragen und die Klappe um die Falzrille 10 umgeschwenkt, sodass die Haftkleberschicht 14 auf die mit der Trennmittelschicht 16 versehene Stelle 15 der Innenseite der Kuvertvorderseite zu liegen kommt, wodurch das Kuvert gebrauchsbereit oder verpackungsbereit ist.If the envelope has to be printed on the inside or outside or on both sides, the paper web drawn off from a paper roll with a constant width is periodically printed as required, i.e. as required, so that the distance between the beginnings of the repeating printing areas is the length of the Sash matches. Then the release agent 16 is attached to the locations 15. Afterwards, in the case of window envelopes, the window openings are cut out and closed again with transparent material, as is known per se. Subsequently, the transverse grooves 7, 10 and 11 serving as fold grooves are attached. This is followed by the separating cut, through which the seedlings are separated from one another without the formation of waste pieces and the cut edges 5 and 6 are produced. As can be seen from the drawing, the cutting edge runs at each of its two ends over a length of approximately 8 mm perpendicular to the lateral boundary edge 2 or 3. Subsequently, it has a section which continues at an obtuse angle while being on the essential Part of its length is perpendicular to the lateral boundary edges 2/3. The adhesive strips 12 and 13 are then applied to the individual die cuts and the back of the envelope 9 is folded around the fold groove 7 and pressed onto the front, where it is held in place by the two adhesive strips 12 and 13. Now the pressure-sensitive adhesive layer 14 is applied to the closure flap 4 and the flap is pivoted around the fold groove 10, so that the pressure-sensitive adhesive layer 14 is open the point 15 provided with the release agent layer 16 comes to lie on the inside of the front of the envelope, as a result of which the envelope is ready for use or ready for packaging.

Aus dem Vorstehenden ist ohne weiteres ersichtlich, dass beim gebrauchsbereiten Kuvert an allen Stellen stets zwei Papierschichten aufeinander liegen. Das Kuvert hat also überall die gleiche Dicke, dies im Unterschied zu den bekannten Kuverts mit Seitenklappen, bei denen an einzelnen Stellen im Bereich der Verschlussklappe bis zu fünf Papierschichten aufeinander liegen, was zur Folge hat, dass sich in einer Versand- oder Lagerschachtel eine wesentlich kleinere Anzahl konventioneller Kuverts unterbringen lässt als dies mit den erfindungsgemässen Kuverts möglich ist. Wenn ein derartig neues Kuvert gebraucht wird, kann das Schriftgut ohne Öffnen der Verschlussklappe eingefüllt werden. Nachher wird die Klappe geöffnet und nicht mehr um die Falzrille 10 sondern um die Falzrille 11 umgelegt, sodass sie aussen auf der Kuvertrückseite 9 aufliegt und durch das übliche Andrücken mit ihr verklebt werden kann.From the foregoing it is readily apparent that when the envelope is ready for use, there are always two layers of paper on top of each other. The envelope therefore has the same thickness everywhere, in contrast to the known envelopes with side flaps, in which up to five layers of paper lie on top of each other at individual points in the area of the closure flap, which means that there is a significant amount in a shipping or storage box can accommodate a smaller number of conventional envelopes than is possible with the envelopes according to the invention. If such a new envelope is needed, the documents can be filled in without opening the flap. Afterwards, the flap is opened and no longer folded around the fold groove 10 but around the fold groove 11, so that it rests on the outside of the envelope 9 and can be glued to it by the usual pressing.

Bei der Herstellung eines erfindungsgemässen Kuvert der vorbeschriebenen Art lässt sich etwas Fabrikationszeit dadurch einsparen, dass man von einer Papierbahn ausgeht, deren Breite einem Mehrfachen, beispielsweise dem Doppelten der Kuvertbreite entspricht, und von dieser Papierbahn Doppelstänzlinge abtrennt, wie einer in der Fig. 2 dargestellt und als Ganzes mit 21 bezeichnet ist, und diesen dann in der Längsrichtung der ursprünglichen Papierbahn, also durch einen Schnitt nach der Linie 22 in zwei Teile 23 und 24 trennt, von denen jeder mit dem eingangs beschriebenen Stänzling übereinstimmt. Selbstverständlich lassen sich auf diese Art und Weise Kuverts nicht nur in allen Normgrössen sondern auch in jeglicher Spezialgrösse herstellen.When manufacturing an envelope according to the invention of the type described above, some manufacturing time can be saved by starting with a paper web whose width corresponds to a multiple, for example twice the envelope width, and separating double die cuts from this paper web, as shown in FIG. 2 and is designated as a whole by 21, and then separates it in the longitudinal direction of the original paper web, that is to say by a cut along line 22, into two parts 23 and 24, each of which corresponds to the diecut described at the beginning. Of course, envelopes can not only be produced in this way in all standard sizes, but also in any special size.
