Abstract

The closure clip (10) is made of elastic plastic for closing bags made of plastic film for packaging purposes and the like which have two clamping arms (14; 16) which are connected to one another so as to be swivellable in the region of one of their ends in each case and are provided in the region of their other end in each case with catch elements which can be brought into detachable engagement. The clamping arms (14; 16) each have a limb portion (18; 22) extending spaced apart and essentially in parallel in the closed position of the closure clip (10). Projecting from the flat side facing the other clamping arm limb portion (22, 18) in each case of at least one of the clamping arms is a clamping extension (20), whose height, measured from the assigned limb portion, is selected such that the clear spacing, present between the limb portions (18, 22) in the closed position, is at least largely bridged by the clamping extension (20) or the clamping extensions. <IMAGE>

Description

Die Erfindung betrifft einen Verschluß-Klip aus elastisch eingestelltem Kunststoff zum Verschließen von Folienbeuteln für Verpackungszwecke u.dgl. mit zwei im Bereich jeweils ei­nes ihrer Enden verschwenkbar miteinander verbundenen Klemm­armen, die im Bereich ihres jeweils anderen Endes mit in lös­baren Verbindungseingriff bringbaren Rastelementen versehen sind.The invention relates to a closure clip made of elastically adjusted plastic for closing foil bags for packaging and the like. with two clamping arms pivotally connected to each other in the area of each of their ends, which are provided in the area of their respective other ends with locking elements which can be brought into releasable connection engagement.

Solche Verschluß-Klips dienen zum Verschließen der üblichen Verpackungsbeutel aus Kunststoffolie derart, daß das im Beu­tel enthaltene Verpackungsgut nach dem Öffnen des Verschluß-­Klips zur Entnahme zugänglich ist, der Beutel aber bei nur teilweiser Leerung nach Möglichkeit auch wieder verschließbar ist. Zum Verschließen des Beutels wird dieser im Bereich sei­ner Öffnung zusammengerafft und - eventuell - leicht gedreht, worauf der Verschluß-Klip mit entrasteten und geöffneten Klemmarmen über den verdrehten Beutel-Öffnungsbereich geführt und dann durch Druck auf die geöffneten Endbereiche der Klemmarme geschlossen wird.Such closure clips are used to close the usual packaging bags made of plastic film in such a way that the packaging material contained in the bag is accessible for removal after opening the closure clip, but the bag can also be closed again if only partially emptied. To close the bag, the bag is gathered in the area of its opening and - possibly - slightly rotated, whereupon the closure clip with the unlocked and opened clamping arms is guided over the twisted bag opening area and then closed by pressure on the opened end areas of the clamping arms.

Der Erfindung liegt die Aufgabe zugrunde, Verschluß-Klips dieser Art so auszubilden, daß sie einen dichten und festen, d.h. gegen ungewolltes Abziehen vom Beutel gesicherten Ver­schluß auch von Beuteln unterschiedlicher Größe gewährlei­sten, wobei die Klips ohne Schwierigkeiten - erforderlichen­falls auch mehrfach - geöffnet und geschlossen werden können.The invention has for its object to form closure clips of this type so that they have a tight and firm, i.e. Ensure closure of bags of different sizes secured against unwanted removal from the bag, the clips being able to be opened and closed without difficulty — if necessary also several times.

Ausgehend von einem Verschluß-Klip der eingangs erwähnten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die Klemmarme jeweils einen in der geschlossenen Stellung des Verschluß-Klips mit Abstand und im wesentlichen parallel ver­laufenden Schenkelabschnitt aufweisen, und daß von der dem jeweils anderen Klemmarm-Schenkelabschnitt zugewandten Flach­seite wenigstens eines der Klemmarme ein Klemmansatz vor­springt, dessen bzw. deren von zugeordneten Schenklabschnitt gemessene Höhe so gewählt ist, daß der in geschlossener Stel­lung zwischen den Schenkelabschnitten bestehende lichte Ab­stand von dem Klemmansatz bzw. den Klemmansätzen zumindest weitgehend überbrückt wird. Ein mit einem derartigen Ver­schluß-Klip verschlossener Beutel wird also durch Einklemmen des zusammengerafften Beutel-Mündungsbereichs zwischen den Klemmansätzen bzw. - sofern nur ein solcher Klemmansatz vor­gesehen ist - zwischen dem Klemmansatz und dem zweiten Klem­marm zusammengedrückt, wobei aufgrund der dabei auftretenden federelastischen Verformung der Klemmarme eine Klemmkraft auf den Beutel-Mündungsbereich ausgeübt wird, so daß ein dichter und festsitzender Verschluß gegeben ist.Starting from a locking clip of the type mentioned in the introduction, this object is achieved according to the invention in that the clamping arms each have a leg section which is spaced and essentially parallel in the closed position of the locking clip, and that of the other clamping arm leg section facing flat side of at least one of the clamping arms projects a clamping projection, the height of which is measured by the associated leg section is selected so that the clear distance between the leg sections in the closed position is at least largely bridged by the clamping projection or the clamping projections. A bag closed with such a closure clip is thus clamped of the gathered bag mouth area between the clamping lugs or - if only such a clamping lug is provided - compressed between the clamping lug and the second clamping arm, a clamping force being exerted on the bag mouth area due to the spring-elastic deformation of the clamping arms that occurs, so that a tight and tight closure is given.

Dabei kann die Ausgestaltung so getroffen sein, daß von der Flachseite eines Schenkelabschnitts ein Klemmansatz vortritt, dessen Höhe etwa gleich dem lichten Abstand zwischen den Schenkelabschnitten der in der Schließstellung befindlichen Klemmarme ist. Alternativ kann von der Flachseite der Klemm­arm-Schenkelabschnitte jeweils wenigstens ein Klemmansatz vorspringen, deren Höhe dann jeweils etwa dem halben lichten Abstand zwischen den Klemmarm-Schenkelabschnitten bemessen ist.The configuration can be such that a clamping projection emerges from the flat side of a leg section, the height of which is approximately equal to the clear distance between the leg sections of the clamping arms located in the closed position. Alternatively, at least one clamping projection can protrude from the flat side of the clamping arm leg sections, the height of which is then in each case dimensioned approximately half the clear distance between the clamping arm leg sections.

Der jeweils einem Schwenkelbereich zugeordnete Klemmansatz kann auch durch wenigstens einen von der freien Klemmkante des jeweiligen Klemmansatzes aus im wesentlichen bis zur Flachseite des jeweiligen Schenkelabschnitts geführten Ein­schnitt in jeweils wenigstens zwei - oder mehr - Klemmab­schnitte unterteilt sein. Dadurch wird eine sich nach außen durchwölbende Verbiegung der Klemmarme erleichtert, die be­sonders dann zweckmäßig ist, wenn ein relativ großer Beutel verschlossen werden soll, d.h. der zusammengeraffte und - ggf. - verdrehte Mündungsbereich des Verpackungsbeutels rela­tiv dick ist. Der bzw. die Einschnitte haben zweckmäßig eine sich in Richtung zur Flachseite des zugehörigen Klemmarm-­Schenkelabschnitts V-förmig verjüngende Ausgestaltung. Da­durch wird gewährleistet, daß die Klemmarme sich nach außen durchwölben können, ohne daß die Klemmarm-Abschnitte diese Verwölbung dadurch behindern, daß die die Einschnitte begren­zenden Flächen vorzeitig aneinander zur Anlage kommen.The respective clamping lug assigned to a swivel region can also be divided into at least two - or more - clamping sections by at least one cut made from the free clamping edge of the respective clamping lug essentially up to the flat side of the respective leg section. This facilitates an outwardly bulging bending of the clamping arms, which is particularly useful when a relatively large bag is to be closed, i.e. the gathered and - possibly - twisted mouth region of the packaging bag is relatively thick. The incision or incisions expediently have a configuration which tapers in a V-shape in the direction of the flat side of the associated clamping arm leg section. This ensures that the clamping arms can bulge outwards without the clamping arm sections hindering this curvature in that the surfaces delimiting the incisions come into contact with one another prematurely.

Die beiden Klemmarme sind zweckmäßig durch ein Filmscharnier verschwenkbar verbunden.The two clamping arms are suitably pivotally connected by a film hinge.

Die Rastelemente werden in einer vorteilhaften Weiterbildung der Erfindung von in der Nähe der freien Enden der Klemmarme von deren dem jeweils anderen Klemmarm zugewandten Flachseite vortretenden leistenartigen Ansätzen gebildet, deren freie Ränder gegensinnig hakenartig umgekantet werden. Die dabei gebildeten hakenartigen Umkantungen können also miteinander verrastet werden.The locking elements are in an advantageous development the invention of in the vicinity of the free ends of the clamping arms formed by their strip-like approaches which face the other clamping arm facing the flat side, the free edges of which are folded in opposite directions in a hook-like manner. The hook-like folds formed in this way can therefore be locked together.

An dem an seinem freien Rand hakenartig in Richtung zur Schwenkverbindung der Klemmarme umgekantete leistenartigen Ansatz ist in vorteilhafter Weiterbildung der Erfindung eine als Entrastungshebel vorgesehene leistenartige Handhabe ange­formt, deren freier Rand von der schwenkbaren Verbindung der Klemmarme wegweist. Durch Druck auf das freie Ende dieser Handhabe und das freie Ende des zugeordneten Klemmarms wird der zugeordnete leistenartige Ansatz so elastisch verbogen, daß dessen Umkantung aus dem Rasteingriff mit der Umkantung des zweiten leistenartigen Ansatzes außer Eingriff kommt und die beiden Klemmarme dann aufgeschwenkt werden können.In an advantageous development of the invention, a strip-like handle provided as a release lever is molded onto the strip-like approach which is folded over on its free edge in the manner of a hook in the direction of the pivoting connection of the clamping arms, the free edge of which points away from the pivotable connection of the clamping arms. By pressing the free end of this handle and the free end of the associated clamping arm, the associated strip-like extension is bent so elastically that its edge comes out of engagement with the edge of the second strip-like extension and the two clamping arms can then be swung open.

Der in der geschlossenen Stellung zwischen den Klemmarmen be­stehende - und durch den Klemmansatz bzw. die Klemmansätze weitgehend überbrückte - lichte Abstand wird in zweckmäßiger Weiterbildung durch die Länge eines vom Schaftabschnitt eines der Klemmarme abgewinkelten Distanzabschnitts bestimmt, wobei - ggf. - das Filmscharnier das Ende dieses Distanzabschnitts mit dem Schaftabschnitt des anderen Klemmarms verbindet.The clear distance existing in the closed position between the clamping arms - and largely bridged by the clamping attachment or the clamping attachments - is determined in an expedient development by the length of a spaced portion angled from the shaft section of one of the clamping arms, with - if necessary - the film hinge at the end of this Spacer section connects to the shaft section of the other clamping arm.

Die Erfindung ist in der folgenden Beschreibung zweier Aus­führungsbeispiele in Verbindung mit der Zeichnung näher er­läutert, und zwar zeigen:

  • Fig. 1 und 2 jeweils eine perspektivische Ansicht eines ersten Ausführungsbeispiels des erfin­dungsgemäßen Verschluß-Klips in der geöffne­ten bzw. geschlossenen Stellung; und
  • Fig. 3 und 4 jeweils eine perspektivische Ansicht eines zweiten Ausführungsbeispiels des erfin­dungsgemäßen Verschluß-Klips in der geöffne­ten bzw. geschlossenen Stellung.
The invention is explained in more detail in the following description of two exemplary embodiments in conjunction with the drawing, namely:
  • Figures 1 and 2 each show a perspective view of a first embodiment of the closure clip according to the invention in the open or closed position; and
  • 3 and 4 are each a perspective view of a second embodiment of the closure clip according to the invention in the open or closed position.

Der in den Figuren 1 und 2 gezeigte, in seiner Gesamtheit mit 10 bezeichnete Verschluß-Klip ist ein einstückiger Spritzguß­teil aus einem elastisch eingestellten Kunststoff, der in Fig. 1 in geöffnetem Zustand und in Fig. 2 in der Schließ­stellung dargestellt ist.The closure clip shown in FIGS. 1 and 2, designated in its entirety by 10, is a one-piece injection molded part made of an elastically adjusted plastic, which is shown in FIG. 1 in the open state and in FIG. 2 in the closed position.

Der Verschluß-Klip 10 weist zwei über ein Filmscharnier 12 verschwenkbar miteinander verbundene Klemmarme 14 bzw. 16 auf, von denen der Klemmarm 14 von einem langgestreckten, im wesentlichen rechteckigen Schaftabschnitt 18 gebildet wird, von dessen in der Schließstellung dem anderen Klemmarm 16 zu­gewandter Flachseite ein rippenartiger Klemmansatz 20 vor­steht.The closure clip 10 has two clamping arms 14 and 16, which are pivotally connected to one another via a film hinge 12, of which the clamping arm 14 is formed by an elongated, essentially rectangular shaft section 18, from the flat side of which, in the closed position, faces the other clamping arm 16 rib-like clamping projection 20 protrudes.

Vom Klemmarm 16 ist dagegen am unteren Ende des dem Schen­kelabschnitt 18 des Klemmarms 14 entsprechenden Schwenkelab­schnitts 22 ein Distanzabschnitt 24 abgewinkelt. Das Film­scharnier 12 verbindet das freie Ende dieses Distanzab­schnitts 24 mit dem Schaftabschnitt 18 des Klemmarms 14.By contrast, a spacing section 24 is angled from the clamping arm 16 at the lower end of the swivel section 22 corresponding to the leg section 18 of the clamping arm 14. The film hinge 12 connects the free end of this spacer section 24 to the shaft section 18 of the clamping arm 14.

Die rechtwinklig zur Flachseite des Schaftabschnitts 18 ge­messene Höhe des Klemmansatzes 20 entspricht etwa der Länge des Distanzabschnitts 24 bzw. ist nur geringfügig kleiner.The height of the clamping projection 20 measured at right angles to the flat side of the shaft section 18 corresponds approximately to the length of the spacer section 24 or is only slightly smaller.

Etwas unterhalb des oberen freien Randes tritt von der Innen­fläche jedes Klemmarms 14, 16 jeweils ein in Querrichtung verlaufender leistenartiger Ansatz 26, 28 vor, die an ihren freien Enden jeweils eine gegensinnige hakenartige Umkantung 30, 32 aufweisen. Die rechtwinklig von den Flachseiten der Schaftabschnitte 18, 22 der Klemmarme 16 gemessene Länge der Ansätze 26, 28 ist dabei so gewählt, daß die Umkantungen 30, 32 in der in Fig. 2 veranschaulichten Schließstellung, in welcher die Schaftabschnitte 18, 22 etwa parallel verlaufen, miteinander verhakt sind, d.h. in Rasteingriff stehen und so ein Auseinanderschwenken der Klemmarme 14, 16 in die in Fig. 1 gezeigte Öffnungsstellung verhindern.Somewhat below the upper free edge occurs from the inner surface of each clamping arm 14, 16 a strip-like extension 26, 28 running in the transverse direction, each of which has an opposite hook-like edge 30, 32 at its free ends. The length of the lugs 26, 28, measured at right angles from the flat sides of the shaft sections 18, 22 of the clamping arms 16, is selected such that the folds 30, 32 in the closed position illustrated in FIG. 2, in which the shaft sections 18, 22 run approximately parallel , are hooked together, ie are in latching engagement and thus prevent the clamping arms 14, 16 from pivoting apart into the open position shown in FIG. 1.

Von der oberen Flachseite des leistenartigen Ansatzes 26 steht eine querverlaufende Handhabe 34 vor, die als Entra­ stungshebel dient. Wenn auf das freie Ende dieses Entra­stungshebels 34 und das überstehende obere Ende des Schaftab­schnitts 18 des Klemmarms 14 mit dem Daumen und dem Zeige­finger ein aufeinanderzu gerichteter Druck ausgeübt wird, verbiegt sich der leistenförmige Ansatz 26 elastisch derart, daß die an seinem freien Ende ausgebildete Umkantung 30 aus dem Rasteingriff mit der Umkantung 32 freikommt und die Klemmarme dann auseinandergeschwenkt werden können, wofür die den Verschluß-Klip 10 bedienende Person mit der zweiten Hand das obere freie Ende des Klemmarms 16 vom Klemmarm 14 weg­zieht.A transverse handle 34 protrudes from the upper flat side of the strip-like extension 26, which acts as an entra lever serves. If pressure is applied to the free end of this release lever 34 and the projecting upper end of the shaft section 18 of the clamping arm 14 with the thumb and the index finger, the strip-shaped extension 26 bends elastically in such a way that the fold 30 formed at its free end comes out of the locking engagement with the edge 32 and the clamping arms can then be pivoted apart, for which the person operating the locking clip 10 pulls the upper free end of the clamping arm 16 away from the clamping arm 14 with the second hand.

Der in den Figuren 3 und 4 gezeigte Verschluß-Klip 110 ent­spricht dem vorstehend beschriebenen Verschluß-Klip 10 weit­gehend, so daß es genügt, nachstehend nur die getroffenen Ab­wandlungen im einzelnen zu beschreiben, während für die über­einstimmenden Ausgestaltungsmerkmale auf die vorausgehende Beschreibung der Figuren 1 und 2 verwiesen werden kann, zumal gleichen Teilen beider Verschluß-Klips in den Zeichnungsfigu­ren gleiche Bezugszeichen zugeordnet sind, denen im Falle des Verschluß-Klips 110 allerdings - zur Unterscheidung vom Ver­schluß-Klip 10 - eine "1" vorangestellt ist.The closure clip 110 shown in FIGS. 3 and 4 largely corresponds to the closure clip 10 described above, so that it suffices to describe only the modifications made in detail below, while for the corresponding design features refer to the preceding description of FIGS. 1 and 2, especially since the same parts of the two locking clips in the drawing figures are assigned the same reference numerals, which, however, in the case of the locking clip 110 are preceded by a "1" to distinguish them from the locking clip 10.

Ein wesentlicher Unterschied zwischen den beiden Verschluß-­Klips besteht darin, daß anstelle des vom Schaftabschnitt 18 vorstehenden und den lichten Abstand zwischen den Schen­kelabschnitten 18, 22 im wesentlichen überbrückenden leisten­artigen Klemmansatzes 20 beim Verschluß-Klip 110 von den In­nenflächen beider Schaftabschnitte 118 und 122 jeweils Klemmansätze 120a bzw. 120b halber Höhe vortreten, die in der Breite massiver als der rippenartige Klemmansatz 20 bemessen sind, dafür jedoch durch jeweils einen von der freien Klemm­kante des jeweiligen Klemmansatzes 120a, 120b aus im wesent­lichen bis zur Flachseite des jeweiligen Schenkelabschnitts 118, 122 geführten, sich V-förmig verjüngenden Einschnitt 121 in jeweils zwei Klemmansatz-Abschnitte 121a, 121b unterteilt sind. Dadurch ist es möglich, daß sich die Schaftabschnitte elastisch nach außen verbiegen können, wenn - beispielsweise bei einem relativ großen Beutel - das zwischen den Klemman­sätzen in der Schließstellung zusammenzudrückende Material relativ dick ist. Durch die erwähnte V-Form der Einschnitte 21 wird eine solche elastische Verwölbung der Schaftab­schnitte 118, 122 nicht behindert.An essential difference between the two closure clips is that instead of the protruding from the shaft section 18 and the clear distance between the leg sections 18, 22 essentially bridging strip-like clamping projection 20 in the closure clip 110 from the inner surfaces of both shaft sections 118 and 122 each clamping approaches 120a or 120b occur at half the height, which are dimensioned to be more solid in width than the rib-like clamping projection 20, but instead by one led from the free clamping edge of the respective clamping projection 120a, 120b essentially to the flat side of the respective leg section 118, 122, the V-shaped tapered incision 121 is divided into two clamping attachment portions 121a, 121b. This makes it possible for the shaft sections to bend elastically outwards when, for example in the case of a relatively large bag, the material to be compressed between the clamping lugs in the closed position is relatively thick. Such an elastic curvature of the shaft sections 118, 122 is not impeded by the aforementioned V-shape of the incisions 21.

Eine weitere Abwandlung des Verschluß-Klips 110 besteht darin, daß der Schaftabschnitt 122 noch über den rechtwinklig abgewinkelten Distanzabschnitt 124 nach unten vorsteht und so eine Handhabe 123 bildet, welche das Öffnen des Klips 110 nach dessen Entrastung durch Druck auf die Handhabe 134 und den oberen freien Rand des Schaftabschnitts 122 erleichtert.A further modification of the locking clip 110 is that the shaft section 122 still protrudes downward beyond the right-angled spacing section 124 and thus forms a handle 123, which opens the clip 110 after it has been released by pressing on the handle 134 and the upper one free edge of the shaft portion 122 facilitated.
