Definitions
- the invention relates to an envelope, in particular a photo laboratory work bag, with a closure flap which can be folded over on the opening side on one envelope wall, the front wall, and can be folded over towards the other envelope wall, the rear wall, which flap can be glued to the rear wall by means of an adhesive label stuck over a die cut.
- Material and with or without a window envelopes often serve as photo laboratory work bags for receiving the films and photos to be worked out in a photo laboratory, but they are also used as letter envelopes or generally as storage bags for various objects.
- These envelopes should be able to be closed quickly and neatly by simply folding the flap over and they should also be able to be stacked on top of one another in any number, without fear of sticking together.
- the adhesive labels on the back that is to say on the outside of the envelope, must be specially prepared by silicone coating or the like, so that when the envelopes are stacked on one another the labels which are then one above the other are prevented from sticking together.
- these special adhesive labels are relatively expensive and increase the total manufacturing effort.
- at least the rear wall of the known envelopes consists of a plastic film or the like, which further increases the material and cost involved in the manufacture of the envelope.
- the invention is therefore based on the object to remedy these shortcomings and to create an envelope of the type described, which can be rationally manufactured and which is further characterized by a label-free printing area which covers the entire front surface including the flap.
- the invention solves this problem in that the cutout is in the rear wall and the adhesive label is glued from the inside of the envelope over the open cutout and in that the front wall has a separating lacquer layer on the outside in its area opposite the cutout, advantageously using a silicon-containing synthetic resin lacquer Separating lacquer layer forms.
- the arrangement of the punching in the rear wall makes the entire front wall together with the flap perfect free and enables full-surface printing.
- the cut-out on the back wall with the label on the inside offers a neat image even when the flap is open and conventional labels can be used as labels without any treatment of the back.
- the release varnish that can be applied without difficulty in the course of the envelope production or printing in the area opposite to the punched-out area on the outside of the front wall ensures that any number of envelopes are stacked on one another without adhesive, since this release varnish has a repulsive effect and does not bond with the adhesive of the label.
- the wall thickness of the back wall prevents the envelope lying on top of one another from being pressed directly onto the adhesive layer of the label lying inside the back wall, as a result of which the stacked envelopes are prevented from sticking.
- the release varnish itself is transparent, can be written on and printed on, so that it does not impair the front wall design, regardless of when it is applied.
- the adhesive label can also be stuck from the inside of the envelope over the punched-out section still covered with the punched-out part, the punched-out part hanging detachably in the punched-out connection webs interrupting the circumferential punched line.
- This stamped part which is still available for the time being, thus covers the adhesive label from the outside, so that there are no longer any free adhesive spots and the envelopes can be stacked on one another in any manner and completely without risk.
- the punched part is only pulled off when necessary, which is clean due to the punched line which forms a predetermined tear line and is only interrupted by the connecting webs and with a handle, and the envelope can be closed properly.
- the cover is preferably made of non-fibrous paper or the like, or at least the punched-out rear wall area.
- the closure flap has a film or a connecting lacquer layer on the inside in its area that can be folded over onto the punched-out area, so that the flap can be detached from the adhesive label in any case and independently of the remaining envelope material and a repeated, proper closing and opening of the flap is guaranteed.
- Conventional overpressure connection varnishes preferably a nitrocellulose varnish, are suitable as the connection varnish, the material and production expenditure remaining minimal due to the small surface area of the film or the connection varnish layer.
- the envelopes are made from a cohesive blank that forms the front and back walls, including the flap and possibly a tear-off strip, which results in the desired envelope due to folding and gluing on the side, the cut-out can be rationally prefabricated during the production of the blank and the adhesive label easily folded before folding or pieces of film and the lacquer layers are applied at the locations assigned to them, which enables material-saving, particularly economical envelope production.
- An envelope 1 consists of a front wall 2 and a rear wall 3, a flap 5 projecting above the opening 4 of the envelope being attached to the front wall 2, from which a tear-off strip 7 can be separated by means of a perforation line 6.
- a punch 8 is provided just below the edge 4 forming the edge, via which an adhesive label 9 is glued from the inside of the envelope, so that the adhesive area within the punch 8 is used to glue the flap 5 which can be folded towards the rear wall 3 can be.
- a layer 10 of connecting lacquer or a film is applied, so that the closure flap 5, even if it consists of fibrous material, can be closed and opened again several times without loss of the adhesive effect.
- the punched-out 8 is open from the outset and therefore the adhesive label 9 is accessible from the outside.
- a separating lacquer layer 11 is applied to the outside of the front wall 2 in the area opposite the punched-out area 8, which layer has an adhesive-repelling effect and therefore cannot stick to the adhesive label 9.
- the adhesive label 9 can, however, also be covered by the punched-out part 12, which is still remaining in the punched-out 8, in order to get by without a separating lacquer layer and to be able to stack the envelopes 1 safely on one another.
- This part 12 hangs only via connecting webs 14, which interrupt the circumferential punching line 13, detachably in the punching 8, so that it can be pulled off at any time along the predetermined tear line given by the punching line 13.
- a suitable adhesive and / or a non-fibrous material of the stamped part 12 or the rear wall 3 or the entire envelope 1 that can be peeled off from the adhesive must of course be provided. If the part 12 is removed, the adhesive point of the adhesive label 9 is exposed and the closure flap 5 can be closed again by folding it down and pressing it down.
- the envelope 1 can be produced rationally and in a material-saving manner, for example by prefabricating a uniform blank 1a, which comprises the front wall 2, rear wall 3 and closure flap 5 together with lateral adhesive tabs 15 and already with the punched-out 8 and on the inside with the adhesive label 9 and optionally the connecting lacquer layer 10 and is provided on the outside with the release lacquer layer 11 (FIG. 2).
- a uniform blank 1a which comprises the front wall 2, rear wall 3 and closure flap 5 together with lateral adhesive tabs 15 and already with the punched-out 8 and on the inside with the adhesive label 9 and optionally the connecting lacquer layer 10 and is provided on the outside with the release lacquer layer 11 (FIG. 2).
- an envelope 1 (FIG. 1) is produced in a rational manner, which is also characterized by its full-surface printability, which includes the entire front wall and closure flap.
- one or more viewing windows can be provided in the rear wall 3 or in the front wall 2, and there is inherently full freedom for the actual design of the envelope and

Abstract
Description
Die Erfindung bezieht sich auf einen Umschlag, insbesondere Fotolaborarbeitstasche, mit einer öffnungsseitig an der einen Umschlagwand, der Vorderwand, angesetzten und zur anderen Umschlagwand, der Rückwand, hin umklappbaren Verschlußklappe, die umgeklappt an der Rückwand mittels eines über eine Ausstanzung geklebten Klebeetiketts festklebbar ist.The invention relates to an envelope, in particular a photo laboratory work bag, with a closure flap which can be folded over on the opening side on one envelope wall, the front wall, and can be folded over towards the other envelope wall, the rear wall, which flap can be glued to the rear wall by means of an adhesive label stuck over a die cut.
Solche im wesentlichen aus Papier od. dgl. Material und mit oder ohne Sichtfenster hergestellten Umschläge dienen häufig als Fotolaborarbeitstaschen zur Aufnahme der in einem Fotolabor auszuarbeitenden Filme und Fotos, sie werden aber auch als Briefkuverts oder allgemein als Aufnahmetaschen für verschiedenste Gegenstände verwendet. Diese Umschläge sollen sich dabei durch einfaches Umklappen der Verschlußklappe schnell und sauber verschließen lassen und sie sollen auch, ohne ein Zusammenkleben befürchten zu müssen, einwandfrei und in beliebiger Anzahl übereinandergestapelt werden können. Wie aus dem DE-GM 78 34 984, der DE-PS 31 37 681 bzw. AT-PS 377 104, oder der CH-PS 356 077 und den US-PSen 3 079 066 und 3 256 941 hervorgeht, sind bisher bei den bekannten Umschlägen die Ausstanzungen in der Verschlußklappe oder dem als Verschluß dienenden Vorderwandteil angeordnet und die Klebeetikette außen über diese Ausstanzungen geklebt, so daß die Etikette bei auf- und zugeklappter Verschlußklappe sichtbar sind und den optischen Eindruck der Umschläge beeinträchtigen. Vor allem aber wird durch die Etikette der Aufdruckbereich an der Vorderwand geschmälert, was gerade bei der Verwendung als Fotolaborarbeitstasche recht unerwünscht ist, da hier neben Informationen und Felder zur Beschriftung u. dgl. möglichst großflächige Werbeaufdrucke Platz finden sollen. Abgesehen davon, müssen die Klebeetikette an ihrer Rückseite, also an der Umschlagaußenseite, durch Silikonbeschichtung od. dgl. speziell präpariert sein, damit beim Aufeinanderstapeln der Umschläge ein Zusammenkleben der dann übereinander liegenden Etikette verhindert wird. Diese speziellen Klebeetikette sind aber relativ teuer und erhöhen den gesamten Herstellungsaufwand. Um außerdem einen mehrmals verwendbaren Klebeverschluß zu erreichen, besteht bei den bekannten Umschlägen zumindest die Rückwand aus einer Kunststoffolie od. dgl., was den Material- und Kostenaufwand bei der Umschlagherstellung weiter steigert.Such essentially made of paper or the like. Material and with or without a window envelopes often serve as photo laboratory work bags for receiving the films and photos to be worked out in a photo laboratory, but they are also used as letter envelopes or generally as storage bags for various objects. These envelopes should be able to be closed quickly and neatly by simply folding the flap over and they should also be able to be stacked on top of one another in any number, without fear of sticking together. As can be seen from DE-GM 78 34 984, DE-PS 31 37 681 and AT-PS 377 104, or CH-PS 356 077 and US Pat. Nos. 3,079,066 and 3,256,941, have so far been disclosed in the Known envelopes arranged the punched holes in the flap or the front wall part serving as a closure and glued the adhesive label outside over these punched-outs so that the label is visible when the flap is open and closed and the visual impression of the Envelopes affect. Above all, however, the label reduces the print area on the front wall, which is particularly undesirable when used as a photo laboratory work bag, since here, in addition to information and fields for labeling and. Like. Large-scale advertising prints should find space. Apart from this, the adhesive labels on the back, that is to say on the outside of the envelope, must be specially prepared by silicone coating or the like, so that when the envelopes are stacked on one another the labels which are then one above the other are prevented from sticking together. However, these special adhesive labels are relatively expensive and increase the total manufacturing effort. In order to also achieve a reusable adhesive closure, at least the rear wall of the known envelopes consists of a plastic film or the like, which further increases the material and cost involved in the manufacture of the envelope.
Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und einen Umschlag der eingangs geschilderten Art zu schaffen, der sich rationell fertigen läßt und der sich darüber hinaus durch einen die Vorderwand samt Verschlußklappe ganzflächig erfassenden etikettfreien Aufdruckbereich auszeichnet.The invention is therefore based on the object to remedy these shortcomings and to create an envelope of the type described, which can be rationally manufactured and which is further characterized by a label-free printing area which covers the entire front surface including the flap.
Die Erfindung löst diese Aufgabe dadurch, daß die Ausstanzung in der Rückwand liegt und das Klebeetikett von der Umschlaginnenseite her über die offene Ausstanzung geklebt ist und daß die Vorderwand an der Außenseite in ihrem der Ausstanzung gegenüberliegenden Bereich eine Trennlackschicht aufweist, wobei vorteilhafterweise ein siliziumhältiger Kunstharzlack die Trennlackschicht bildet. Die Anordnung der Ausstanzung in der Rückwand macht die gesamte Vorderwand zusammen mit der Verschlußklappe vollkommen frei und ermöglicht ganzflächige Aufdrucke. Die an der Rückwand vorgesehene Ausstanzung mit dem innenliegenden Etikett bietet auch bei offener Verschlußklappe ein ordentliches Bild und als Etikette können herkömmliche Etikette ohne jegliche Behandlung der Rückseite verwendet werden. Der im Zuge der Umschlagherstellung oder Bedrukkung ohne Schwierigkeiten aufzubringende Trennlack im der Ausstanzung gegenüberliegenden Bereich an der Vorderwandaußenseite gewährleistet das klebefreie Aufeinanderstapeln beliebig vieler Umschläge, da dieser Trennlack eine abstoßende Wirkung zeigt und sich nicht mit dem Kleber des Etiketts verbindet. Zusätzlich verhindert dabei die Wandstärke der Rückwand ein unmittelbar flächiges Aufeinanderdrücken des aufliegenden Umschlages auf die Klebeschicht der innerhalb der Rückwand liegenden Etikette, wodurch ein Haftenbleiben der aufeinandergestapelten Umschläge ausgeschlossen ist. Der Trennlack selbst ist durchsichtig, läßt sich beschreiben und bedrucken, so daß er unabhängig vom Zeitpunkt seines Aufbringens keinerlei Beeinträchtigung der Vorderwandgestaltung mit sich bringt.The invention solves this problem in that the cutout is in the rear wall and the adhesive label is glued from the inside of the envelope over the open cutout and in that the front wall has a separating lacquer layer on the outside in its area opposite the cutout, advantageously using a silicon-containing synthetic resin lacquer Separating lacquer layer forms. The arrangement of the punching in the rear wall makes the entire front wall together with the flap perfect free and enables full-surface printing. The cut-out on the back wall with the label on the inside offers a neat image even when the flap is open and conventional labels can be used as labels without any treatment of the back. The release varnish that can be applied without difficulty in the course of the envelope production or printing in the area opposite to the punched-out area on the outside of the front wall ensures that any number of envelopes are stacked on one another without adhesive, since this release varnish has a repulsive effect and does not bond with the adhesive of the label. In addition, the wall thickness of the back wall prevents the envelope lying on top of one another from being pressed directly onto the adhesive layer of the label lying inside the back wall, as a result of which the stacked envelopes are prevented from sticking. The release varnish itself is transparent, can be written on and printed on, so that it does not impair the front wall design, regardless of when it is applied.
Zur Vermeidung der Trennlackschicht kann nach einer anderen Ausgestaltung der Erfindung das Klebeetikett von der Umschlaginnenseite her auch über die noch mit dem ausgestanzten Teil abgedeckte Ausstanzung geklebt sein, wobei der ausgestanzte Teil durch die umfangseitige Stanzlinie unterbrechende Verbindungsstege lösbar in der Ausstanzung hängt. Dieser vorerst noch vorhandene Stanzteil deckt somit das Klebeetikett nach außen hin ab, so daß es keine freie Klebestelle mehr gibt und die Umschläge beliebig und vollkommen gefahrlos aufeinander stapelbar sind. Erst bei Bedarf wird der Stanzteil abgezogen, was durch die eine Sollreißlinie bildende, nur von den Verbindungsstegen unterbrochene Stanzlinie sauber und mit einem Griff möglich ist, und der Umschlag kann ordnungsgemäß verschlossen werden. Damit es hier zu keinem Haftenbleiben von Materialfasern od. dgl. am Klebeetikett kommen kann, besteht vorzugsweise der Umschlag, zumindest aber der die Ausstanzung aufweisende Rückwandbereich aus einem nichtfasernden Papier od. dgl. Material.To avoid the release lacquer layer, according to another embodiment of the invention, the adhesive label can also be stuck from the inside of the envelope over the punched-out section still covered with the punched-out part, the punched-out part hanging detachably in the punched-out connection webs interrupting the circumferential punched line. This stamped part, which is still available for the time being, thus covers the adhesive label from the outside, so that there are no longer any free adhesive spots and the envelopes can be stacked on one another in any manner and completely without risk. The punched part is only pulled off when necessary, which is clean due to the punched line which forms a predetermined tear line and is only interrupted by the connecting webs and with a handle, and the envelope can be closed properly. To prevent material fibers or the like from sticking to the adhesive label here, the cover is preferably made of non-fibrous paper or the like, or at least the punched-out rear wall area.
Um einen mehrmalig verwendbaren Klebeverschluß sicherzustellen, trägt erfindungsgemäß die Verschlußklappe an der Innenseite in ihrem auf die Ausstanzung umklappbaren Bereich eine Folie oder eine Verbindungslackschicht, so daß sich die Klappe auf jeden Fall und unabhängig vom übrigen Umschlagmaterial rückstandsfrei von dem Klebeetikett lösen läßt und ein mehrmaliges, einwandfreies Schließen und Öffnen der Verschlußklappe gewährleistet ist. Als Verbindungslack eignen sich herkömmliche Überdruck-Verbindungslacke, vorzugsweise ein Nitrocelluloselack, wobei auch hier durch die Kleinflächigkeit der Folie oder der Verbindungslackschicht der Material- und Herstellungsaufwand minimal bleibt. Werden die Umschläge aus einem zusammenhängenden, Vorder- und Rückwand samt Verschlußklappe und eventuell anschließendem Abreißstreifen bildenden Zuschnitt hergestellt, der durch Falten und seitliches Verkleben den gewünschten Umschlag ergibt, kann rationell bei der Herstellung des Zuschnittes auch die Ausstanzung vorgefertigt und vor dem Zusammenfalten problemlos die Klebeetikette bzw. Folienstückchen und die Lackschichten an den ihnen zugeordneten Stellen aufgebracht werden, wodurch eine materialsparende, besonders wirtschaftliche Umschlagherstellung möglich ist.In order to ensure a reusable adhesive closure, according to the invention the closure flap has a film or a connecting lacquer layer on the inside in its area that can be folded over onto the punched-out area, so that the flap can be detached from the adhesive label in any case and independently of the remaining envelope material and a repeated, proper closing and opening of the flap is guaranteed. Conventional overpressure connection varnishes, preferably a nitrocellulose varnish, are suitable as the connection varnish, the material and production expenditure remaining minimal due to the small surface area of the film or the connection varnish layer. If the envelopes are made from a cohesive blank that forms the front and back walls, including the flap and possibly a tear-off strip, which results in the desired envelope due to folding and gluing on the side, the cut-out can be rationally prefabricated during the production of the blank and the adhesive label easily folded before folding or pieces of film and the lacquer layers are applied at the locations assigned to them, which enables material-saving, particularly economical envelope production.

Ein Umschlag 1 besteht aus einer Vorderwand 2 und einer Rückwand 3, wobei an der Vorderwand 2 eine über die Öffnung 4 des Umschlages hochragende Verschlußklappe 5 angesetzt ist, von der mittels einer Perforationslinie 6 ein Abreißstreifen 7 abtrennbar sein kann. In der Rückwand 3 ist knapp unterhalb der die Öffnung 4 bildenden Randkante eine Ausstanzung 8 vorgesehen, über die von der Umschlaginnenseite her ein Klebeetikett 9 geklebt ist, so daß der klebende Bereich innerhalb der Ausstanzung 8 zum Festkleben der zur Rückwand 3 hin umklappbaren Verschlußklappe 5 genutzt werden kann.An
Im auf die Ausstanzung 8 umklappbaren Bereich an der Innenseite der Verschlußklappe 5 ist eine Schicht 10 aus Verbindungslack oder einer Folie aufgebracht, so daß sich die Verschlußklappe 5, auch wenn sie aus faserndem Material besteht, mehrmals ohne Verlust der Klebewirkung schließen und wieder öffnen läßt.In the foldable area on the punched-out
Beim Ausführungsbeispiel nach Fig. 1 und 2 ist die Ausstanzung 8 von vornherein offen und daher das Klebeetikett 9 von außen zugänglich. Um hier ein gegenseitiges Festkleben aufeinandergestapelter Umschläge 1 zu verhindern, ist an der Vorderwand 2 außenseitig im der Ausstanzung 8 gegenüberliegenden Bereich eine Trennlackschicht 11 aufgetragen, die eine kleberabstoßende Wirkung besitzt und daher mit dem Klebeetikett 9 nicht verkleben kann.In the exemplary embodiment according to FIGS. 1 and 2, the punched-out 8 is open from the outset and therefore the adhesive label 9 is accessible from the outside. In order to prevent mutual sticking of
Wie in Fig. 3 angedeutet, kann das Klebeetikett 9 aber auch vom ausgestanzten, aber noch in der Ausstanzung 8 verbleibenden Teil 12 abgedeckt werden, um ohne Trennlackschicht auszukommen und die Umschläge 1 gefahrlos aufeinanderstapeln zu können. Dieser Teil 12 hängt dabei nur über Verbindungsstege 14, die die umfangseitige Stanzlinie 13 unterbrechen, lösbar in der Ausstanzung 8, so daß er jederzeit bei Bedarf entlang der durch die Stanzlinie 13 gegebenen Sollreißlinie abgezogen werden kann. Um dabei nicht ein Haftenbleiben am Etikett befürchten zu müssen, ist selbstverständlich für ein entsprechendes Klebemittel und/oder ein vom Kleber abziehbares, nicht faserndes Material des Stanzteiles 12 bzw. der Rückwand 3 oder des ganzen Umschlages 1 zu sorgen. Ist der Teil 12 entfernt, liegt die Klebestelle des Klebeetiketts 9 frei und die Verschlußklappe 5 kann wieder durch Umklappen und Niederdrücken verschlossen werden.As indicated in FIG. 3, the adhesive label 9 can, however, also be covered by the punched-out
Der Umschlag 1 läßt sich rationell und materialsparend herstellen, indem beispielsweise ein einheitlicher Zuschnitt 1a vorgefertigt wird, der Vorderwand 2, Rückwand 3 und Verschlußklappe 5 samt seitlichen Klebelaschen 15 umfaßt und bereits mit der Ausstanzung 8 und innenseitig mit dem Klebeetikett 9 und gegebenenfalls der Verbindungslackschicht 10 sowie außenseitig mit der Trennlackschicht 11 versehen ist (Fig. 2). Durch entsprechendes Zusammenfalten und Zusammenkleben dieses Zuschnittes 1a entsteht auf rationelle Weise ein Umschlag 1 (Fig. 1), der sich zudem durch seine die gesamte Vorderwand und Verschlußklappe einbeziehende, ganzflächige Bedruckbarkeit auszeichnet. Selbstverständlich kann dabei in der Rückwand 3 oder auch in der Vorderwand 2 ein oder mehrere Sichtfenster vorgesehen sein und für die eigentliche Ausgestaltung des Umschlages und die Materialwahl besteht an und für sich volle Freiheit.The
