The invention relates to an adhesive-tape dispenser (1) having a holder (2) for accommodating a wound-up adhesive-tape roll (4) such that it can be rotated about an axis (3), and having an outer part (5) which is connected to the holder (2), is located radially outside an inserted adhesive-tape roll (4), or one which can be inserted, and has an adhering surface which is directed towards an adhesive-containing side of the adhesive tape (7) and on which the end of the adhesive tape (7) can be secured. The adhesive-tape dispenser is improved in that the rear side (9) of the outer part (5) is of non-adhering design.

Description

Die Erfindung betrifft einen Klebebandspender mit einer Halterung zur um eine Achse drehbaren Aufnahme eines aufgewickelten Klebebandwickels und mit einem mit der Halterung verbundenen Außenteil, der sich radial außerhalb eines eingesetzten oder einsetzbaren Klebebandwickels befindet und der eine der mit Klebstoff versehenen Seite des Klebebandes zugewandte Anhaftfläche zum Festhalten des Endes des Klebebandes aufweist.The invention relates to an adhesive tape dispenser with a holder for rotatable about an axis recording of a wound tape roll and an outer part connected to the holder, which is located radially outside of an inserted or insertable tape roll and one of the provided with adhesive side of the adhesive tape adhering surface for holding having the end of the adhesive tape.

Klebebandspender und Klebebandabrollvorrichtungen sind in verschiedenen Ausführungen allgemein bekannt. Sie dienen dazu, zu Klebebandwickeln aufgewickelte Klebebänder aufzunehmen und das Abwickeln der Klebebänder zu erleichtern. So sind beispielsweise Klebebandspender bekannt, bei denen ein Klebebandwickel vollständig oder teilweise in einem Gehäuse aufgenommen und in diesem zum Abwickeln eines Klebebandstücks um eine Achse herum drehbar gelagert sind. Dazu weist das Gehäuse oftmals um die Drehachse herum ausgerichtete Vorsprünge auf, auf denen eine üblicherweise aus Kunststoff bestehende Kernrolle mit dem darauf aufgewickelten Klebebandwickel gelagert wird. Weiterhin weist das Gehäuse eine Abtrennvorrichtung zum Abtrennen eines vom Klebebandwickels abgezogenen Klebebandstücks sowie einen Anhaftteil zum Festhalten und leichten Wiederaufgreifen des freien Endes des Klebebandwickels auf. Der Anhaftteil dient dazu, nach dem Abtrennen eines Klebebandstücks das neue freie Ende des Klebebandes durch leichtes Aufkleben in einer für den Benutzer leicht greifbaren Position festzuhalten und ein Rückfallen auf den Klebebandwickel zu verhindern, wo das freie Ende des Klebebands oftmals nur schwer zu erkennen und von dem Klebebandwickel wieder ab zu lösen ist.Tape dispensers and tape roll-off devices are well known in various designs. They serve to absorb tapes wrapped in adhesive tape and to facilitate the unwinding of the tapes. For example, adhesive tape dispensers are known in which an adhesive tape roll is completely or partially received in a housing and rotatably mounted therein for unwinding an adhesive tape piece about an axis. For this purpose, the housing often on the axis of rotation around aligned projections on which a usually made of plastic core roll is stored with the wound thereon tape roll. Furthermore, the housing has a separating device for separating an adhesive tape piece drawn off from the adhesive tape roll, and an adhesive part for holding and lightly re-gripping the free end of the adhesive tape roll. The adhesive part serves to hold the new free end of the tape by gently sticking in a position easily accessible to the user after the removal of an adhesive tape piece and to prevent falling back on the tape roll where the free end of the tape is often difficult to recognize and from the tape roll is to be detached again.

Neben Klebebandspendern bzw. Klebebandabrollgeräten mit einem im Vergleich zum Bandwickel großen Standgehäuse sind spezielle Klebebandspender bekannt, die kein Standgehäuse aufweisen und bei denen der Bandhalteteil im wesentlichen von zwei Halteelementen in einer Position relativ zu dem Bandwickel gehalten wird. Ein solcher Klebebandspender ist beispielsweise in der AU1977967 und in der DE 10 342 085 offenbart. Solche Klebebandspender ohne Standgehäuse dienen primär dazu, einen Außenteil, welcher eine Anhaftfläche auf einer Seite aufweist, zum leichteren Wiederauffinden des Endes des Klebebandes und eine häufig damit verbundene Abtrennvorrichtung zur Verfügung zu stellen.In addition to tape dispensers or Klebebandabrollgeräten with a large compared to the tape winding stand housing special adhesive tape dispensers are known which have no housing stand and in which the tape holding member is held by two holding elements in a position relative to the tape roll substantially. Such a tape dispenser is for example in the AU1977967 and in the DE 10 342 085 disclosed. Such tape dispensers without pedestals serve primarily to provide an outer member having an adhesive surface on one side for ease of retrieval of the end of the adhesive tape and a severing device often associated therewith.

Derartige Klebebandspender weisen jedoch den Nachteil auf, dass das Klebeband auf der Rückseite des Außenteils anhaften kann, wenn beispielsweise das freie Ende des Klebebandes auf der Anhaftfläche anhaftet und das Klebeband zwischen der Anhaftfläche und dem Klebebandwickel nicht straff gespannt ist. Dies kann beispielsweise dadurch verursacht werden, dass durch irgendeinen Umstand der Klebebandwickel in Abrollrichtung gedreht wird, wenn das freie Ende des Klebebandes auf der Anhaftfläche angeheftet ist und so Klebeband von dem Bandwickel abgerollt wird, welches eine lose Schlaufe bilden kann. Dies kann insbesondere durch den Transport solcher Klebebandspender in Taschen verursacht werden. Diese Schlaufe des Klebebandes kann dann auf der Rückseite des Außenteils anhaften und dort fest kleben.However, such tape dispensers have the disadvantage that the adhesive tape can adhere to the back of the outer part, for example, if the free end of the adhesive tape adheres to the adhesive surface and the tape between the adhesive surface and the tape roll is not taut. This may be caused, for example, by rotating the tape roll in the unwinding direction by any circumstance when the free end of the tape is adhered to the adherend surface, thus unwinding tape from the tape roll which may form a loose loop. This can be caused in particular by the transport of such tape dispensers in pockets. This loop of the adhesive tape can then adhere to the back of the outer part and stick firmly there.

Beim Wiederaufgreifen des auf der Anhaftfläche haftenden freien Endes des Klebebandes kann dieses zwar einfach von der Anhaftfläche gelöst werden, jedoch wird beim anschließenden Abziehen des Klebebandes von der Rückseite des Außenteils das Klebeband häufig beschädigt.When picking up the adhering to the adhesive surface free end of the adhesive tape while this can be easily solved by the adhesive surface, however, the adhesive tape is often damaged in the subsequent removal of the adhesive tape from the back of the outer part.

Die Aufgabe der Erfindung besteht darin, eine Verbesserung vorzuschlagen, die ein Anhaften auf der Rückseite des Außenteils verhindert und damit ein einfaches Wiederaufgreifen des freien Endes des Klebebandes vereinfacht.The object of the invention is to propose an improvement which prevents adhesion to the back of the outer part and thus simplifies a simple recapture of the free end of the adhesive tape.

Diese Aufgabe wird für einen Klebebandspender mit einer Halterung zur um eine Achse drehbaren Aufnahme eines aufgewickelten Klebebandwickels und mit einem mit der Halterung verbundenen Außenteil, der sich radial außerhalb eines eingesetzten oder einsetzbaren Klebebandwickels befindet und der eine der mit Klebstoff versehenen Seite des Klebebandes zugewandte Anhaftfläche zum Festhalten des freien Endes des Klebebandes aufweist, dadurch gelöst, dass die Rückseite des Außenteils nicht haftend ausgebildet ist.This object is for an adhesive tape dispenser with a holder for rotatable about an axis recording of a wound tape roll and an outer part connected to the holder, which is located radially outside of an inserted or usable tape roll and one of the adhesive side of the adhesive tape facing the adhesive surface Holding the free end of the adhesive tape, solved by the fact that the back of the outer part is not adhesive.

Die Ausbildung der Rückseite der Außenteils mit der Eigenschaft des Nichthaftens bewirkt, dass in dem Fall, dass das Klebeband mit seiner Klebeseite an der Rückseite des Außenteils anliegt, das Klebeband nicht an dieser Fläche anhaftet und somit beim nächsten Aufgreifen des losen Endes des Klebebandes einfach von dem Klebebandwickel weiter abgerollt werden kann. Die Haftkraft ist durch die Eigenschaft des Nichthaftens so weit reduziert, dass das Klebeband durch einfaches Ziehen an dem losen Ende des Bandes von der Rückseite des Außenteils gelöst wird, auch wenn das Klebeband im Wesentlichen in der vorgesehenen Abrollrichtung abgezogen wird.The formation of the back of the outer part with the property of non-adherence causes in the event that the adhesive tape with its adhesive side against the back of the outer part, the adhesive tape does not adhere to this surface and thus the next picking up the loose end of the adhesive tape of easy the tape roll can be further unrolled. The adhesive force is reduced so far by the property of non-sticking that the adhesive tape is released by simply pulling on the loose end of the tape from the back of the outer part, even if the tape is pulled off substantially in the intended unwinding direction.

Diese Eigenschaft des Nichthaftens des Klebebandes auf der Rückseite des Außenteils kann beispielsweise dadurch bewirkt werden, dass die Oberfläche ausreichend rau ist, so dass der auf dem Klebeband angebrachte Klebstoff nur mit einer sehr kleinen Oberfläche in Kontakt kommen kann und damit nur eine geringe Haftwirkung bewirken kann.This non-sticking property of the adhesive tape on the back surface of the outer member can be effected, for example, by making the surface sufficiently rough so that the adhesive applied to the adhesive tape can come into contact only with a very small surface and thus cause only a small adhesion ,

In einer vorteilhaften Ausführungsform kann die Eigenschaft des Nichthaftens dadurch bewirkt werden, dass die Oberfläche der Rückseite des Außenteils Riefen aufweist. Durch diese Riefen entstehen auf der Oberfläche der Rückseite des Außenteils Erhöhungen zwischen den Riefen. Da das Klebeband nicht auf der Fläche der Riefen, sondern nur auf den Erhöhungen anhaften kann, steht damit nur eine geringe Fläche zur Verfügung, auf der das Klebeband haften kann. Die sich ergebende Haftkraft des Klebebandes auf der Rückseite des Außenteils ist demzufolge sehr gering.In an advantageous embodiment, the property of non-adherence may be effected by the surface of the back of the outer part having grooves. By these grooves arise on the surface of the back of the outer part increases between the grooves. Since the adhesive tape can not adhere to the surface of the grooves, but only on the elevations, so there is only a small area available on which the tape can adhere. The resulting adhesive force of the adhesive tape on the back of the outer part is therefore very small.

In einer alternativen Ausführungsform können die Riefen parallel zur Abrollrichtung des Klebebandes ausgerichtet sein, so dass die Erhöhungen der Oberfläche in die Zähne der am Ende des Außenteils angebrachten Abtrenneinrichtung übergehen. Für den Fall, dass das Klebeband auf dieser Fläche, also der Rückseite des Außenteils anhaften sollte, kann dieses entsprechend gleichmäßig und leicht abgezogen werden, da das Klebeband nicht über seine gesamte Breite anhaftet.In an alternative embodiment, the grooves can be aligned parallel to the unwinding direction of the adhesive tape, so that the elevations of the surface merge into the teeth of the separating device attached to the end of the outer part. In the event that the tape should adhere to this surface, so the back of the outer part, this can be correspondingly evenly and easily removed because the tape does not adhere over its entire width.

Eine Ausrichtung der Riefen quer zur Abrollrichtung des Klebebandes kann jedoch dann vorteilhaft sein, wenn das Außenteil bei normalem Gebrauch auf dem Klebebandwickel aufliegt, so dass das Außenteil mit mindestens einer Erhöhung auf der gesamten Breite des Klebebandes aufliegt. Bei einer Ausrichtung der Rillen in Abrollrichtung würde das Außenteil nur an denjenigen Punkte auf dem Bandwickel aufliegen, die als Kreuzungspunkt der linienförmigen Berge mit der konvexen Oberfläche des Klebebandwickels gegeben sind. Diese vergleichsweise kleinen Auflagepunkte könnten das noch auf dem Klebebandwickel aufgerollte Klebeband möglicherweise beschädigen, so dass hier ein Ausrichtung der Riefen quer zur Abrollrichtung des Klebebandes vorteilhaft ist.An orientation of the grooves transversely to the unwinding of the adhesive tape, however, may be advantageous if the outer part rests on the adhesive tape roll during normal use, so that the outer part rests with at least one increase over the entire width of the adhesive tape. In an alignment of the grooves in the unwinding direction, the outer part would only rest on those points on the tape roll, which are given as a crossing point of the line-shaped mountains with the convex surface of the adhesive tape roll. These comparatively small contact points could possibly damage the adhesive tape still rolled up on the adhesive tape roll, so that an orientation of the grooves transverse to the unwinding direction of the adhesive tape is advantageous here.

In einer weiteren Ausführungsform kann die gewünschte Eigenschaft des Nichthaftens des Klebebandes auf der Rückseite des Außenteils dadurch bewirkt werden, dass diese Fläche eine Antihaftbeschichtung aufweist. Eine solche Antihaftbeschichtung kann beispielsweise Polytetrafluorethylen sein, welches in einer dünnen Schicht auf die Oberfläche der Rückseite des Außenteils aufgebracht ist. Alternativ dazu könnte die Oberfläche der Rückseite des Außenteils silikonisiert sein, auf welchem ein Klebeband ebenso wie auf Polytetrafluorethylen nur sehr gering anhaftet.In a further embodiment, the desired property of non-adherence of the adhesive tape to the back of the outer member may be effected by having this surface coated with a non-stick coating. Such a non-stick coating may be, for example, polytetrafluoroethylene, which is applied in a thin layer on the surface of the back of the outer part. Alternatively, the surface of the back of the outer part could be siliconized, on which an adhesive tape as well as on polytetrafluoroethylene adheres only very slightly.

In einer weiteren vorteilhaften Ausführungsform kann die Oberfläche der Rückseite des Außenteils konvex ausgeformt sein. In dem Falle, dass bei normalem Gebrauch des Klebebandspenders der Außenteil auf dem Klebebandwickel aufliegt würde die Klebebandschlaufe nur in einem kleinen Bereich auf die Rückseite des Außenteils aufgedrückt, so dass das Klebeband nur mit einer vergleichsweise kleinen Stelle der Rückseite des Außenteils in Kontakt käme.In a further advantageous embodiment, the surface of the back of the outer part may be formed convex. In the event that in normal use of the tape dispenser, the outer part rests on the tape roll wrap the tape loop would only in a small Pressed area on the back of the outer part, so that the tape would come into contact only with a relatively small point of the back of the outer part.

Schließlich kann die Rückseite des Außenteils nur in einem Teilbereich nicht haftend ausgebildet sein, so dass die Rückseite nur in demjenigen Bereich die besagte Eigenschaft aufweist, in dem erfahrungsgemäß in dem geschildertem Fall das Klebeband anhaftet.Finally, the rear side of the outer part can not be adhesively formed in only a partial area, so that the rear side only has the said property in that area in which experience has shown that the adhesive tape adheres in the described case.

Im Folgenden wird eine beispielhafte Ausführungsform anhand der Figuren näher beschrieben. Es zeigt

Figur 1:
eine perspektivische Ansicht eines Klebebandspenders
In the following, an exemplary embodiment will be described in more detail with reference to FIGS. It shows
FIG. 1:
a perspective view of an adhesive tape dispenser

Figur 1 zeigt einen Klebebandspender 1 mit einer Halterung 2 zur um eine Achse 3 drehbaren Aufnahme eines aufgewickelten Klebebandwickels 4. Der Klebebandspender 1 weist einen Außenteil 5 auf, welcher mit der Halterung 2 über zwei elastische Federarme 6 verbunden ist. Die elastischen Federarme 6 sind dabei so ausgebildet, dass der Außenteil 5 immer auf der Oberfläche des Klebebandwickels 4 aufliegt und dem sich beim Abziehen des Klebebandes 7 verringernden Durchmesser des Klebebandwickels 4 folgt. Bei normalem Gebrauch des Klebebandspenders 1 liegt das freie Ende des Klebebandes 7 auf der radialen Außenseite des Außenteils 5 auf. Der Außenteil 5 ist auf seiner radialen Außenseite geriffelt und bildet so eine Anhaftfläche 8, auf der das freie Ende des Klebebandes 7 nur wenig haftet. Das freie Ende des Klebebandes 7 kann somit einfach von der Anhaftfläche 8 aufgegriffen werden, um das Klebeband 7 von dem Klebebandwickel 4 abzuziehen. Wenn das abgezogene Stück des Klebebandes 7 abgetrennt ist, wird das verbleibende freie Ende des Klebebandes 7 wieder auf der Anhaftfläche 8 angeheftet, so dass das Ende für das nächste Aufgreifen bereit ist. FIG. 1 shows an adhesive tape dispenser 1 with a holder 2 for rotatable about an axis 3 recording a wound tape roll 4. The tape dispenser 1 has an outer part 5, which is connected to the holder 2 via two elastic spring arms 6. The elastic spring arms 6 are designed so that the outer part 5 always rests on the surface of the adhesive tape roll 4 and the subsequent reduction of the adhesive tape 7 diameter of the adhesive tape roll 4 follows. In normal use of the adhesive tape dispenser 1, the free end of the adhesive tape 7 rests on the radial outer side of the outer part 5. The outer part 5 is corrugated on its radial outer side and thus forms an adhesion surface 8, on which the free end of the adhesive tape 7 only slightly adheres. The free end of the adhesive tape 7 can thus be easily picked up by the adhesive surface 8 in order to remove the adhesive tape 7 from the adhesive tape roll 4. When the peeled-off piece of the adhesive tape 7 is cut off, the remaining free end of the adhesive tape 7 is re-attached to the adhering surface 8 so that the end is ready for the next picking up.

Bei einem Gebrauch des Klebebandspenders 1 wie vorgesehen befindet sich die Stelle, an der das Klebeband 7 sich von dem Klebebandwickel 4 löst in unmittelbarer Nähe des Außenteils 5 und das Klebeband 7 haftet an der Anhaftfläche 8.When using the adhesive tape dispenser 1 as intended, the point at which the adhesive tape 7 separates from the adhesive tape roll 4 is in the immediate vicinity of the outer part 5 and the adhesive tape 7 adheres to the adhesive surface 8.

Es besteht nun die Gefahr, dass der Klebebandwickel 4 gegenüber dem Klebebandspender 1 in Abrollrichtung gedreht wird, ohne dass das Klebeband 7 abgezogen wird, sondern stattdessen das Klebeband 7 weiter auf der Anhaftfläche 8 anhaftet. Dies führt dazu, dass die Stelle, an der sich das Klebeband 7 von dem Klebebandwickel 4 ablöst, an dem Außenteil 5 vorbei bewegt wird und sich in vielen Fällen eine gestrichelt dargestellte Klebebandschlaufe 10 bildet, wobei das Klebeband 7 auf der Rückseite 9 des Außenteils 8 kleben bleibt. Um beim nächsten Abziehen des Klebebandes 7 dieses von dem Klebebandwickel 4 abziehen zu können, muss zunächst das Klebeband von der Rückseite 9 des Außenteils 5 abgelöst werden, da nach dem Lösen des losen Endes des Klebebandes 7 von der Anhaftfläche 8 das Klebeband nicht von dem Klebebandwickel 4 abziehbar ist, da es auf der Rückseite 9 des Außenteils 5 anhaftet und sich bei herkömmlichen Klebebandspendern durch das Ziehen an dem Ende des Klebebandes 7 nicht allein durch den Zug ablöst.There is now the risk that the adhesive tape roll 4 is rotated in the unwinding direction relative to the adhesive tape dispenser 1, without the adhesive tape 7 being pulled off, but instead adhering the adhesive tape 7 further to the adhesive surface 8. As a result, the point at which the adhesive tape 7 separates from the adhesive tape roll 4 is moved past the outer part 5 and, in many cases, forms an adhesive tape loop 10 shown in dashed lines, the adhesive tape 7 resting on the back 9 of the outer part 8 sticking. In order to be able to remove this from the adhesive tape roll 4 the next time the adhesive tape 7 is peeled off, the adhesive tape must first be removed from the back 9 of the outer part 5, since after releasing the loose end of the adhesive tape 7 from the adhesive surface 8, the adhesive tape will not fall off the adhesive tape roll 4 is removable, since it adheres to the back 9 of the outer part 5 and does not detach in conventional adhesive tape dispensers by pulling on the end of the adhesive tape 7 not only by the train.

Die Rückseite 9 des Außenteils 5 ist nun so ausgestaltet, dass das Klebeband 7 auf dieser Fläche nahezu nicht mehr anhaftet. In dem dargestellten Ausführungsbeispiel weist die Rückseite 9 des Außenteils 5 dazu Riefen auf, die quer zur Abrollrichtung des Klebebandes 7 angeordnet sind. Diese bewirken, dass in dem geschilderten Fall das Klebeband 7 nur auf einer sehr geringen Oberfläche, nämlich den Erhöhungen zwischen den Riefen anhaften kann, so dass das Klebeband nur mit äußerst geringer Klebewirkung hier anhaftet. Als weitere Maßnahme zur Verringerung der Haftwirkung des Klebebandes 7 auf der Rückseite 9 des Außenteils 5 ist die Oberfläche konvex ausgeformt, so dass in dem Falle, dass durch das Drehen des Klebebandwickels 4 eine Klebebandschlaufe in Abrollrichtung hinter dem Außenteil 5 entstanden ist, die Form der Oberfläche möglichst nicht der Form der Klebebandschlaufe 10 folgt, um damit die Wahrscheinlichkeit zu verringern, dass das Klebeband 7 auf einer großen Fläche anhaften kann.The back 9 of the outer part 5 is now designed so that the adhesive tape 7 almost no longer adheres to this surface. In the illustrated embodiment, the rear side 9 of the outer part 5 has grooves which are arranged transversely to the rolling direction of the adhesive tape 7. These cause that in the described case, the adhesive tape 7 can adhere only on a very small surface, namely the elevations between the grooves, so that the adhesive tape adheres here only with extremely low adhesive effect. As a further measure to reduce the adhesive effect of the adhesive tape 7 on the back 9 of the outer part 5, the surface is convex, so that in the event that an adhesive tape loop is formed in the unwinding behind the outer part 5 by turning the tape roll 4, the shape of the If possible, the surface does not follow the shape of the adhesive tape loop 10 thus reducing the likelihood that the adhesive tape 7 may adhere to a large area.
