Description

Die Erfindung betrifft einen Beutel nach dem Oberbegriff des Anspruchs 1. Derartige Beutel sind aus der EP 2 113 470 A oder der DE 35 08 123 A bekannt. Beutel der hier betrachteten Art werden insbesondere für leichtes stückiges Material wie etwa Toilettenpapierrollen und dergleichen verwandt und sind dann, da sie großvolumig und unhandlich, mit (zumindest) einem Griff zu versehen. Derartige Beutel unterliegen schon unter dem Gesichtspunkt der Materialkostenersparnis, aber auch unter dem Druck öffentlichen Interesses an einer Abfallreduzierung, einem allgemeinen Trend zu immer dünneren Kunststofffolien, wobei inzwischen eine Folienstärke von 40 µm erreicht und auch unterschritten wird.The invention relates to a bag according to the preamble of claim 1. Such bags are from the EP 2 113 470 A or the DE 35 08 123 A known. Bags of the type considered here are used in particular for lightweight lumpy material such as toilet paper rolls and the like and then, as they bulky and unwieldy, to be provided with (at least) a handle. Such bags are already subject to the saving of material costs, but also under the pressure of public interest in a reduction in waste, a general trend towards ever thinner plastic films, which now reaches a film thickness of 40 microns and also falls below.

Eine verringerte Wandstärke lässt sich von der Festigkeit her großenteils durch zugfestere Materialien ausgleichen, um die Belastungen, insbesondere beim maschinellen befüllen solcher Beutel, aufzufangen. Problematisch wird allerdings eine Füllraumgrenze zwischen Füllraum und Griffleiste, die herkömmlich als einfache durchgehende Siegelnaht ausgeführt wird. Mit abnehmender Folienstärke werden allerdings Siegelnähte zunehmend heikel, da die aufeinander liegende dünnen Folien zwar durch Anschmelzen verbunden, aber nicht etwa nach Art einer Trennnaht durchschmolzen und damit durchtrennt werden. Die in herkömmlicher Art mit geringer Folienstärke gefertigten Beutel, bei denen eine Griffleiste typischerweise als doppellagiger Streifen durchgängiger Breite zum Füllraum hin durch eine Siegelnaht und außen parallel dazu durch eine Trennnaht begrenzt ist, unterliegen dann beim üblichen maschinellen Befüllen durch den Fülldruck der Waren und insbesondere auch durch die Öffnungsdichte von Spreizwerkzeugen der Gefahr, dass die Siegelnaht zwischen Füllraum und Griffleiste aufplatzt und dass damit der gefüllte Beutel schadhaft ist.A reduced wall thickness can largely be compensated for by the strength by means of more tensile materials in order to absorb the stresses, in particular when mechanically filling such bags. However, a filling space boundary between the filling space and the handle bar, which is conventionally designed as a simple continuous sealing seam, becomes problematic. With decreasing film thickness, however, sealing seams become increasingly delicate, since the superimposed thin films, although connected by melting, but not melted through in the manner of a separating seam and thus cut through. The manufactured in a conventional manner with low film thickness bag in which a handle is typically limited as a double-layer strip continuous width to the filling through a sealed seam and outside parallel to it by a cutting seam, then subject to the usual machine filling by the filling pressure of the goods and in particular Due to the opening density of spreading tools, the risk that the sealed seam between the filling space and the handle bar bursts and that thus the filled bag is defective.

Aufgabe der Erfindung ist es, einen Beutel der hier betrachteten Art mit einem Füllraum und einer Griffleiste in einer aus dünner siegelfähiger Kunststofffolie herstellbaren Form zu schaffen, wobei ein solcher Beutel beim Befüllen und bei der Handhabung insbesondere auch in dem kritischen Übergangsbereich zwischen Füllraum und Griffleiste robust ist und sich ohne hohen technischen Aufwand in herkömmlicher Weise fertigen lässt.The object of the invention is to provide a bag of the type considered here with a filling space and a handle in a manufacturable from thin sealable plastic film form, such a bag when filling and handling especially in the critical transition region between filling and handle robust is and can be produced in a conventional manner without high technical complexity.

Gemäß der Erfindung wird diese Aufgabe von einem Beutel nach dem Oberbegriff des Anspruchs 1 durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.According to the invention, this object is achieved by a bag according to the preamble of claim 1 by the characterizing features of claim 1.

Es hat sich gezeigt, dass eine Trennnaht, wie sie etwa an Außenkanten verwendet wird, sehr viel belastbarer ausgeführt werden kann als eine Siegelnaht, wenn die Folienstärke verringert wird und insbesondere in einen Bereich von unter 40 µm gelangt. Es hat sich weiter gezeigt, dass die kritischen Belastungen an den Enden der Füllraumgrenze auftreten, wo durch Füllwerkzeuge bzw. Spreizwerkzeuge und auch durch die das Füllgut eingebrachte Ware forcierte Zugkräfte auftreten.It has been found that a parting seam, such as that used at outer edges, can be made much more resilient than a sealed seam if the film thickness is reduced and, in particular, reaches a range of less than 40 μm. It has further been shown that the critical loads occur at the ends of the filling space boundary, where forced forces occur by filling tools or spreading tools and also by the product introduced the filling material.

Somit lässt sich mit einer Modifikation des Beutels, bei der der durch die Trennnaht gebildete Außenrand der Griffleiste an die Füllraumgrenze herangeführt ist, eine gegenüber der herkömmlichen durchgehenden Siegelnaht verbesserte Robustheit des Beutels erzielen.Thus, with a modification of the bag, in which the outer edge of the handle strip formed by the separating seam is brought to the Füllraumgrenze, compared to the conventional continuous sealing seam improved robustness of the bag can be achieved.

Diese Verbesserung ist mit herkömmlichen Mitteln und somit ohne hohen Aufwand erreichbar, da die Trennnaht als Abschlussnaht auch bisher aufzubringen war. Allerdings erhält sie nunmehr eine konturierte, bei der Grifföffnung entsprechend von der Füllraumgrenze beabstandete und sonst an die Füllraumgrenze herangeführte Form. Gegenüber der herkömmlichen Griffleiste konstanter Breite bedingt die konturierte Form allerdings auch üblicherweise Abfallschnippel, die aber mit geringem Aufwand abgegriffen oder abgesaugt werden können.This improvement can be achieved by conventional means and thus without much effort, since the cutting seam was also applied as a final seam so far. However, it now receives a contoured, at the handle opening spaced from the Füllraumgrenze and otherwise brought up to the Füllraumgrenze form. Compared to the conventional handle bar constant width, however, the contoured shape also usually causes Abfallschnippel, but can be tapped or sucked with little effort.

Dabei kann die Trennnaht an die in herkömmlicher Weise vorhandene Siegelnaht, insbesondere eine gerade durchlaufende Sieglelnaht, eng herangeführt werden, um die Siegelnaht dann gegen ein Aufreißen zu stützen bzw. um ein Aufreißen der Siegelnaht dann kritisch in der zweiten Linie abzufangenIn this case, the cutting seam can be brought close to the present in a conventional manner sealed seam, in particular a straight continuous Sieglelnaht to then support the seal against tearing or to catch a tearing of the seal then critically in the second line

Die Trennnaht tritt dort an die Stelle der Siegelnaht.The cutting seam takes the place of the sealed seam.

Weitere Ausgestaltungen der Erfindung ergeben sich aus den Ansprüchen.Further embodiments of the invention will become apparent from the claims.

In der einzigen Figur der Zeichnung ist ein Beutel gemäß der Erfindung in vertriebsfertig flach zusammengelegter Form - teilweise schnittbildlich aufgebrochen - dargestellt.In the sole figure of the drawing, a bag according to the invention in sales ready flat folded form - partially broken cut - shown.

Ein in der Zeichnung insgesamt mit 1 bezeichneter Beutel aus einer unter 40 µm starken Kunststofffolie wird, wie dargestellt, im unbefülltem Zustand flach zusammengelegt, wobei eine Vorderseite 2 und eine Rückseite 3 miteinander auf einer Seite über eine W-förmige Seitenfalte 4 verbunden sind und auf der anderen Seite offen mit unterschiedlichen Endkanten 5, 6 auslaufen. Der leere Beutel 1 in seiner flachen Lage ist fortlaufend aus einem "endlosen" doppelt gelegten Folienband zu fertigen, das in der Zeichnung nach oben läuft und in das die Seitenfalte 4 eingeformt ist, ehe durch Trennnähte wie eine gerade, quer laufende Trennnaht 7 und eine konturierte Trennnaht 8 auf der gegenüberliegenden Seite eine Vereinzelung erzielt wird. Eine Konturlinie 9 deutet mit seitlichen Konturlinien 10 und 11 die Umrisse eines vorangehenden Beutels an.A designated in the drawing as a total of 1 bag from a 40 micron thick plastic film, as shown, folded flat in the unfilled state, with a front 2 and a back 3 are connected to each other on one side via a W-shaped side fold 4 and on the other side open with different end edges 5, 6 leak. The empty bag 1 in its flat position is continuously from an "endless" double-layered film to produce that runs in the drawing upwards and in which the gusset 4 is formed, before dividing seams such as a straight, transverse seam 7 and a contoured seam 8 on the opposite side a separation is achieved. A contour line 9 indicates the contours of a preceding bag with lateral contour lines 10 and 11.

Die W-förmige Seitenfalte 4 gibt dem Beutel bei entsprechender Befüllung eine kantige Quaderform. Ohne die Seitenfalte 4 ließe sich der Beutel - direkt mit Vorderseite 2 und Rückseite 3 in einer Siegelnaht begrenzt - gut an gerundete Befüllungen wie Zellstoffrollen oder dergl. anpassen.The W-shaped side fold 4 gives the bag with an appropriate filling an edgy cuboid shape. Without the gusset 4, the pouch - bounded directly by the front 2 and back 3 in a sealed seam - could easily be adapted to rounded fillings such as cellulose rolls or the like.

Der Beutel 1 weist eine Griffleiste 12 mit einer Grifföffnung 13 auf. Die Grifföffnung 13 ist im vorliegenden Fall nicht als Aussparung, sondern lappenförmig mit einem als offenem Ring geformten ("C"-förmigen) Rand in Form einer Trennnaht 14 gestaltet, die dann die Folienlagen innen längs der lappenförmigen Grifföffnung 13 wie auch außen an der Griffleiste 12 miteinander verbindet. Es versteht sich, dass die Randkontur aber auch durch Stanzen hergestellt werden könnte, wobei die aufeinander liegenden Folienlagen unverbunden bleiben.The bag 1 has a handle bar 12 with a Handle opening 13 on. The handle opening 13 is designed in the present case not as a recess, but flap-shaped with a shaped as an open ring ("C" -shaped) edge in the form of a cutting seam 14, which then the film layers inside along the flap-shaped handle opening 13 as well as outside of the handle 12 connects together. It is understood that the edge contour could also be produced by stamping, wherein the superimposed film layers remain unconnected.

Die Griffleiste 12, in der die Folien flach aufeinander liegen, ist zu einem Füllraum 16, bei dem die Folien zur Aufnahme des Füllguts auseinander gespreizt werden, durch eine Füllraumgrenze 15 abgegrenzt, die mehr der begrifflichen Unterscheidung halber auch in Endbereichen mit einem kleinen Abstand von der Trennnaht 8 eingezeichnet ist, eigentlich aber dort mit der Trennnaht 8 zusammenfällt. Der Füllraum 15 verläuft parallel zur Trennnaht 7, was sowohl für den Zuschnitt der Beutel bei der Fertigung wie auch für das Befüllen vorteilhaft ist. Der Füllraum 16 erstreckt sich dann zwischen der Trennnaht 7 und der Füllraumgrenze 15 in einer (vertikalen) Richtung und von einer Außenkante 17 der beim Befüllen zu entfaltenden Seitenfalte 4 bis zu einer Füllgrenze 18, von der aus die Folien nach einem Befüllen etwa quaderförmig zusammengezogen und längs einer Nahtlinie 19 durch eine Trennnaht verbunden werden. Ein überstehender (Handhabungs-) Bereich, der auch mit Stiftlöchern 20 für ein Abstapeln vorgesehen ist, entfällt nach dem Verschließen des Beutels 1.The handle bar 12, in which the films lie flat on each other, is delimited by a Füllraumgrenze 15 to a filling space 16, in which the films are spread apart for receiving the filling, the more of the conceptual distinction in the end regions with a small distance from the separating seam 8 is located, but actually coincides there with the cutting seam 8. The filling space 15 runs parallel to the separating seam 7, which is advantageous both for the cutting of the bags during production and for filling. The filling space 16 then extends between the separating seam 7 and the filling space boundary 15 in a (vertical) direction and from an outer edge 17 of the side fold 4 to be unfolded during filling up to a filling limit 18, from which the foils are pulled together in a roughly parallelepiped shape after filling along a seam line 19 are connected by a separating seam. An overhanging (handling) area, which is also provided with pin holes 20 for destacking, is omitted after the bag 1 has been closed.

Während herkömmliche Griffleisten bei dieser Art des Beutels mit einer durchgehend gleich bleibenden Breite versehen waren, mit der der gesamte Bereich zwischen der Konturlinie 9 für den vorangehenden Beutel und Füllraumgrenze 15 als Griffleiste verwendet und dem Beutel 1 somit ohne Abfallecken zugeschlagen wurde, hat der erfindungsgemäße Beutel im Bereich der Griffleiste eine besondere Gestaltung. Diese sieht vor, dass die Trennnaht 8 in den Längsabschnitten beiderseits der Grifföffnung 13 an die Füllraumgrenze herangeführt ist. In Außenbereichen 21 und 22 verläuft die Trennnaht 8 unmittelbar längs der Füllraumgrenze 15. Diese Außenbereiche sind beim Befüllen des Beutels kritischen Belastungen ausgesetzt. Ebenso ist der befüllte Beutel bei Transport und Handhabung in diesen Außenbereichen besonders stark belastet. Dementsprechend ist es wichtig, dass an diesen Längsabschnitten der Füllraumgrenze die Trennnaht mit ihrer höheren Festigkeit zur Verfügung steht. Dies schließt nicht aus, innenseitig zur Trennnaht noch eine Siegelnaht vorzusehen, um insbesondere bei kleinteiligem Füllgut die Füllraumgrenze zu schließen. Eine dicht, d.h. bis auf etwa 5 mm hinter einer solchen Siegelnaht längs der Füllraumgrenze 15 verlaufende Trennnaht ist dann in der Lage, die schwächere Siegelnaht gegen ein Aufplatzen abzustützen oder nach einem Aufplatzen hinsichtlich der Füllraumbegrenzung zu vertreten.While conventional handle strips were provided in this type of bag with a consistently constant width, with which the entire area between the contour line 9 for the preceding bag and Füllraumgrenze 15 used as a handle and the bag 1 was thus slammed without waste corners, has the bag according to the invention in the area of the handle a special design. This provides that the separating seam 8 is brought in the longitudinal sections on both sides of the handle opening 13 to the Füllraumgrenze. In outer regions 21 and 22, the separating seam 8 runs directly along the filling space boundary 15. These outer regions are exposed to critical loads during filling of the bag. Likewise, the filled bag is particularly heavily loaded during transport and handling in these outdoor areas. Accordingly, it is important that the separating seam with its higher strength is available at these longitudinal sections of the filling space boundary. This does not preclude providing a sealed seam on the inside to the separating seam in order to close the filling space boundary, in particular in the case of small-sized filling material. A dense, i. up to about 5 mm behind such a seam along the Füllraumgrenze 15 extending seam is then able to support the weaker sealed seam against bursting or represent after a burst in terms of Füllraumbegrenzung.

Im vorliegenden Fall ist beiderseits der Grifföffnung 13 zu den Außenbereichen 21 und 22 hin längs der Füllraumgrenze 15 jeweils ein Stück einer Siegelnaht 23 bzw. 24 gesetzt, um den Füllraum in diesen Zwischen-Bereichen abzuschließen.In the present case, on both sides of the handle opening 13 to the outer regions 21 and 22 along the Füllraumgrenze 15 each have a piece of a sealed seam 23 and 24 set to complete the filling space in these intermediate areas.

Im Bereich der Grifföffnung 13 kann diese, wenn sie mit einer Trennnaht gebildet wird, außenseitig einen entsprechenden Abschluss im Sinne einer Füllraumgrenze bieten. Es versteht sich, dass eine durch Stanzen hergestellte Griffaussparung 13 zum Füllraum hin eine innenseitig durchgehende Siegelnaht begleitet werden könnte, die eine geringere Festigkeit aufweist, allerdings in einem mittleren Bereich auch weniger beansprucht wird.In the region of the handle opening 13, this can, if it is formed with a separating seam, provide the outside a corresponding conclusion in the sense of Füllraumgrenze. It is understood that a handle recess 13 produced by punching could be accompanied towards the filling space by an inner continuous sealing seam, which has a lower strength but is also less stressed in a central region.

Bei dieser Ausführungsform des Beutels wird die Trennnaht 8 über den Füllraum 16 hinaus zur Beutelöffnung hin bis zur Endkante 6 fortgesetzt. Damit fallen allerdings zwischen der Trennnaht 8 und der Endkante 9 des vorangehend hergestellten (offenen) Beutels Abfallstücke an, die mit geläufigen maschinellen Vorrichtungen abgegriffen oder abgesaugt werden. Ansonsten ist aber der Beutel 1 durchaus in einer herkömmlichen Weise zu fertigen und auch in einer herkömmlichen Weise auf den Abpack-Maschinen zu befüllen. Entscheidender Vorteil ist die höhere Nahtfestigkeit der Trennnaht 8 im Bereich der Füllraumgrenze 15, die auch mit extrem verringerten Folienstärken noch einen für das Befüllen und für den weiteren Transport und die Handhabung robusten Beutel ergibt. In this embodiment of the bag, the separating seam 8 is continued beyond the filling space 16 to the bag opening to the end edge 6. However, between the separating seam 8 and the end edge 9 of the previously produced (open) bag fall waste pieces which are tapped off or sucked off with common mechanical devices. Otherwise, however, the bag 1 can certainly be produced in a conventional manner and also filled in a conventional manner on the packaging machines. The decisive advantage is the higher seam strength of the separating seam 8 in the region of the filling space boundary 15, which results in a bag which is robust for filling and for further transport and handling even with extremely reduced film thicknesses.
