Description

Die Erfindung betrifft einen Seitenfaltenbeutel aus einem Kunststoffgewebeverbund, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a gusseted bag made of a plastic fabric composite, according to the preamble of claim 1.

Der Seitenfaltenbeutel umfasst eine Frontwand, eine Rückwand und zwischen der Frontwand und der Rückwand angeordnete Seitenfalten, die durch Faltkanten mit der Frontwand und Rückwand verbunden sind. Der Seitenfaltenbeutel ist aus einem Kunststoffgewebeverbund gefertigt, der eine Polymerfolie an der Beutelaußenseite sowie ein mit der Polymerfolie verbundenes Gewebe aus Polymerbändchen an der Beutelinnenseite aufweist. Das Gewebe und die Polymerfolie an der Beutelaußenseite sind flächig miteinander verbunden und bilden einen festen Kunststoffgewebeverbund. Der flachliegende Seitenfaltenbeutel ist an einem Ende dadurch verschlossen, dass ein Abschnitt der Frontwand sowie Seitenfaltenabschnitte, die zwischen dem Abschnitt der Frontwand und der Rückwand angeordnet sind, unter Bildung einer Bodenfalte auf die Rückwand umgefaltet und mit dieser verbunden sind. Die Front- und Rückwand bilden gleichwertige Beutelflächen. Die Bezeichnung dieser Beutelflächen als "Frontwand" und "Rückwand" soll das leichtere Verständnis der erfindungsgemäßen Lehre ermöglichen und soll keine sachliche Einschränkung darstellen. Zum leichteren Verständnis der beanspruchten technischen Lehre wird im Rahmen der Offenbarung der Erfindung diejenige Beutelfläche, auf die bei der Ausbildung der Bodenfläche Folienabschnitte umgefaltet und befestigt werden, als "Rückwand" bezeichnet.The gusseted bag comprises a front panel, a rear panel and gussets disposed between the front panel and the rear panel connected by fold edges to the front panel and back panel. The gusseted bag is made of a plastic fabric composite, which has a polymer film on the outside of the bag and a polymer tape connected to the polymer film on the inside of the bag. The fabric and the polymer film on the outside of the bag are connected to one another in a flat manner and form a strong plastic fabric composite. The flat side gusset bag is closed at one end by a portion of the front panel and gusset portions disposed between the portion of the front panel and the back panel folded over and joined to the back panel to form a bottom gusset. The front and rear walls form equivalent bag surfaces. The designation of these bag surfaces as a "front wall" and "back wall" is intended to facilitate the understanding of the teaching of the invention and should not represent a material limitation. To facilitate understanding of the claimed technical teaching is in the context of the disclosure of the invention, that bag surface on which are folded and fixed in the formation of the bottom surface film sections, referred to as a "back wall".

Der flachliegende Seitenfaltenbeutel kann an dem offenen Ende befüllt werden und wird nach der Befüllung verschlossen. Der befüllte Seitenfaltenbeutel ist als Verpackungsbeutel insbesondere für schüttfähige Füllgüter wie pelletierte Tiernahrung, Einstreu für Tiere oder ähnliche Materialien vorgesehen. Der Seitenfaltenbeutel ist durch die Verwendung eines Kunststoffgewebeverbundes insbesondere für Großgebinde geeignet, die ein erhebliches Füllvolumen und ein erhebliches Füllgewicht aufweisen. Entsprechende Seitenfaltenbeutel werden in der Praxis auch als Seitenfaltensäcke bezeichnet, wobei diese Begriffe im Rahmen der vorliegenden Erfindung nicht unterschieden werden.The flat gusseted bag can be filled at the open end and closed after filling. The filled gusseted bag is intended as a packaging bag, in particular for pourable products such as pelleted pet food, litter for animals or similar materials. Of the Side gusset bag is suitable by the use of a plastic fabric composite, especially for large containers, which have a considerable filling volume and a considerable filling weight. Corresponding gusseted bags are referred to in practice as gusseted bags, these terms are not distinguished in the context of the present invention.

Seitenfaltenbeutel aus ein- oder mehrlagigen Folien, die nicht durch ein Gewebe verstärkt sind, weisen häufig eine Bodenfläche auf, die durch Siegelnähte geformt ist. Die Siegelnähte erstrecken sich von einer Faltkante an Längsseiten der Front- oder Rückwand unter einem schrägen Winkel in Richtung der Bodenfalte. Die Siegelnähte, die auch als Ecksiegelungen bezeichnet werden, bewirken, dass sich der Boden des Seitenfaltenbeutels besser zu einer ebenen Bodenfläche ausformt, wenn der Seitenfaltenbeutel mit einem Produkt befüllt wird.Gusseted bags of single or multi-ply foils that are not reinforced by a fabric often have a bottom surface formed by seal seams. The sealing seams extend from a folded edge on longitudinal sides of the front or rear wall at an oblique angle in the direction of the bottom fold. The seal seams, also referred to as corner seals, cause the bottom of the gusseted bag to better form a flat bottom surface when the gusseted bag is filled with a product.

Seitenfaltenbeutel, die aus einem Kunststoffgewebeverbund gefertigt sind, weisen in der Praxis keine Siegelnähte zur Ausformung des Bodens auf, da die beutelinnenseitige Gewebefläche sich nicht oder nur schlecht siegeln lässt. Zur Erzeugung einer Siegelnaht sind hohe Siegeltemperaturen notwendig, wobei die Gefahr besteht, dass durch Einbringen einer zu großen Wärmeenergie die Polymerstruktur und Orientierung der Polymerbändchen des Gewebes zerstört wird. Ein weiteres Problem für die Anbringung von Siegelnähten zwischen den Flanken der Seitenfalten und der angrenzenden Frontwand oder Rückwand ist der schlechte Kontakt der zu verbindenden Flächen aufgrund ihrer Gewebestruktur. Seitenfaltenbeutel aus Kunststoffgewebeverbundmaterialien, die ohne Ecksiegelungen an der Bodenfläche ausgebildet sind, haben nach der Befüllung eine optisch schlechte Bodenausformung. Die schlechte Bodenausformung hat auch negative Einflüsse auf das Gebindevolumen, da sich der Füllstand erhöht, wenn der Boden sich nicht richtig aufstellt und dies durch eine höhere Beutelhöhe berücksichtigt werden muss. Das Problem tritt insbesondere bei flachliegenden Seitenfaltenbeuteln mit tiefen Seitenfalten auf, die nach der Befüllung quaderförmige Verpackungen bilden.Side gusset bags, which are made of a plastic fabric composite, have in practice no sealing seams for forming the bottom, since the bag inside fabric surface can not or only badly seal. To produce a sealed seam, high sealing temperatures are necessary, with the risk that the polymer structure and orientation of the polymer ribbon of the fabric is destroyed by the introduction of excessive heat energy. Another problem for the application of sealing seams between the edges of the gussets and the adjacent front wall or back wall is the poor contact of the surfaces to be joined due to their fabric structure. Side gusset bags made of plastic fabric composite materials, which are formed without corner seals on the bottom surface, have after filling a visually poor Bodenausformung. The poor soil formation also has a negative effect on the container volume, since the level increases when the soil is not properly positioned and this by a higher bag height must be considered. The problem occurs especially in flat side gusseted bags with deep gussets, which form after filling cuboidal packaging.

Um an Seitenfaltenbeuteln, die aus einem Kunststoffgewebeverbund gefertigt sind, Siegelnähte zum Ausformen der Bodenfläche anbringen zu können, muss das Gewebe vollflächig oder zumindest abschnittsweise mit einer siegelfähigen Beschichtung versehen werden, die beispielsweise durch eine Extrusionsbeschichtung oder durch Aufbringen eines Hotmelt-Klebstoffes erzeugt wird. Die Verwendung von beschichteten Gewebe aus monoaxial verstreckten Polymerbändchen und einer Beschichtung aus einem siegelfähigen Polymer zur Herstellung von Säcken ist aus EP 2 188 438 B1 bekannt. Die Beschichtung der Gewebefläche eines Kunststoffgewebeverbundmaterials zur Verbesserung der Siegeleigenschaften ist fertigungstechnisch aufwendig und erfordert einen zusätzlichen und mit entsprechenden höheren Kosten verbundenen Materialeinsatz.In order to be able to attach sealing seams for shaping the bottom surface on side-folding bags which are made of a plastic fabric composite, the fabric must be provided over its entire surface or at least in sections with a sealable coating which is produced, for example, by an extrusion coating or by applying a hot-melt adhesive. The use of coated webs of monoaxially drawn polymer ribbons and a sealable polymer coating for making sacks is lacking EP 2 188 438 B1 known. The coating of the fabric surface of a plastic fabric composite material to improve the sealing properties is technically complex and requires an additional and associated with correspondingly higher cost of material.

Aus US 4 373 979 ist es bekannt, ein Gewebe aus Polymerbändchen durch Ultraschallschweißen mit einer Polymerfläche zu verbinden. Am Beispiel eines Seitenfaltenbeutels wird beschrieben, dass das Ultraschallschweißverfahren eingesetzt werden kann, um das Ende eines Folienschlauches zu verschließen. Die durch Ultraschallschweißen erzeugten Schweißpunkte sind in mehreren Reihen angeordnet, die sich quer zur Längsrichtung des Folienschlauches erstrecken. Dabei ist der Abstand zwischen den Schweißpunkten so gewählt, dass jedes Polymerbändchen des Gewebes von einem Schweißpunkt erfasst wird.Out US 4,373,979 It is known to bond a fabric of polymer tape by ultrasonic welding with a polymer surface. The example of a gusseted bag describes that the ultrasonic welding method can be used to close the end of a film tube. The welding spots produced by ultrasonic welding are arranged in several rows, which extend transversely to the longitudinal direction of the film tube. The distance between the welds is chosen so that each polymer ribbon of the fabric is detected by a welding point.

Die GB 1 162 013 A zeigt einen Standbodenbeutel mit einer Seitenfalte, mit darin angeordneten, aus einer Mehrzahl von Schweißpunkten gebildeten unter einem schrägen Winkel verlaufenden Eckschweißnaht.The GB 1 162 013 A shows a stand-up pouch with a gusset, arranged therein, formed from a plurality of welds at an oblique angle Eckschweißnaht.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, einen aus einem Kunststoffgewebeverbund gefertigten Seitenfaltenbeutel so auszubilden, dass er nach der Befüllung eine ebene und standfeste Bodenfläche aufweist.Against this background, the object of the invention is to design a gusset bag made of a plastic fabric composite in such a way that it has a flat and stable bottom surface after filling.

Gegenstand der Erfindung und Lösung dieser Aufgabe ist ein Seitenfaltenbeutel nach Anspruch 1.The object of the invention and solution of this problem is a gusseted bag according to claim 1.

Die Erfindung setzt einen Seitenfaltenbeutel aus einem Kunststoffgewebeverbund voraus mit einer Frontwand, einer Rückwand und zwischen der Frontwand und der Rückwand angeordneten Seitenfalten, die durch Faltkanten mit der Frontwand und der Rückwand verbunden sind. Ein Abschnitt der Frontwand sowie Seitenfaltenabschnitte, die zwischen dem Abschnitt der Frontwand und der Rückwand angeordnet sind, sind unter Bildung einer Bodenfalte auf die Rückwand umgefaltet und mit dieser verbunden. Der durch Falten einer ebenen Materialbahn herstellbare Seitenfaltenbeutel besteht aus einem Kunststoffgewebeverbund, der eine Polymerfolie an der Beutelaußenseite sowie ein mit der Polymerfolie verbundenes Gewebe aus Polymerbändchen an der Beutelinnenseite aufweist. Die Polymerfolie und das Gewebe sind fest miteinander verbunden und bilden einen festen Verbund. Das Gewebe ist unbehandelt und weist an der Beutelinnenseite keine siegelfähige Beschichtung auf. Erfindungsgemäß sind die beutelinnenseitige Gewebefläche der Seitenfalten mit der benachbarten Gewebefläche der Frontwand oder Rückwand durch Eckschweißnähte verbunden, die sich von einer Faltkante an Längsseiten der Front- oder Rückwand unter einem schrägen Winkel in Richtung der Bodenfalte erstrecken. Für die Erfindung wesentlich ist, dass die Eckschweißnähte eine durch Ultraschallschweißen erzeugte Struktur mit einer Rasterung aus einer Vielzahl von punktförmigen oder linienförmigen Schweißstellen aufweisen. Erfindungsgemäß ist eine Rasterung aus einer Vielzahl hintereinander und nebeneinander angeordneter Schweißpunkte vorgesehen. Durch eine lokale Verbindung an einer Vielzahl von Schweißpunkten oder Linien, die beispielsweise parallel ausgerichtet sind oder sich kreuzen, ist die Nahtfestigkeit der Eckschweißnähte in Längs- und Querrichtung der Eckschweißnähte gleichmäßig. Insbesondere tritt an den Nahtkanten der Eckschweißnähte keine signifikante Versprödung auf, wie dies oft beim Heißsiegeln von Polymerfolien unter Verwendung von Heißsiegelbacken beobachtet werden kann.The invention requires a gusseted bag made of a plastic fabric composite with a front wall, a rear wall and disposed between the front wall and the rear wall gussets, which are connected by folding edges with the front wall and the rear wall. A portion of the front wall, as well as gusset portions disposed between the portion of the front wall and the rear wall, are folded over and connected to the back wall to form a bottom fold. The gusseted bag which can be produced by folding a flat material web consists of a plastic fabric composite which has a polymer film on the outside of the bag and a fabric made of polymer tapes connected to the polymer film on the inside of the bag. The polymer film and the fabric are firmly bonded together forming a strong bond. The fabric is untreated and has no sealable coating on the inside of the bag. According to the bag inner side fabric surface of the gussets are connected to the adjacent fabric surface of the front wall or rear wall by Eckschweißnähte extending from a folded edge on the longitudinal sides of the front or rear wall at an oblique angle in the direction of the bottom fold. For the invention is essential that the corner welds a have produced by ultrasonic welding structure with a screening of a plurality of punctiform or linear welds. According to a screening of a plurality of successively and juxtaposed welding points is provided. By a local connection at a plurality of welds or lines, for example, are aligned in parallel or intersect, the seam strength of the corner welds in the longitudinal and transverse direction of the corner welds is uniform. In particular, no significant embrittlement occurs at the seam edges of the corner welds, as can often be observed in heat sealing of polymeric films using heat seal jaws.

Die Eckschweißnähte erstrecken sich zweckmäßig bis zur Bodenfalte. Dabei sind die Eckschweißnähte so ausgerichtet, dass sie mit der Bodenfalte einen Winkel zwischen 30° und 60° einschließen. Gemäß einer bevorzugten Ausführung der Erfindung begrenzen die Eckschweißnähte mit der Bodenfalte und einer randseitigen Faltkante jeweils eine gleichschenklige Dreieckfläche.The Eckschweißnähte extend appropriately to the bottom fold. The corner welds are aligned so that they enclose an angle between 30 ° and 60 ° with the bottom fold. According to a preferred embodiment of the invention, the corner weld seams with the bottom fold and one edge-side fold edge each delimit an isosceles triangular surface.

Das Gewebe des Kunststoffgewebeverbundes kann insbesondere aus einem Geflecht aus bändchenförmigen Polymerstreifen bestehen. Die Polymerstreifen des Geflechtes weisen in Beutellängsrichtung und in Beutelquerrichtung vorzugsweise eine Breite zwischen 2 mm und 5 mm auf, wobei die sich in Beutellängsrichtung und in Beutelquerrichtung erstreckenden Polymerstreifen des Geflechtes insbesondere auch im Wesentlichen dieselbe Breite aufweisen können.The fabric of the plastic fabric composite may in particular consist of a braid of ribbon-shaped polymer strips. The polymer strips of the braid preferably have a width of between 2 mm and 5 mm in the longitudinal direction of the bag and in the transverse direction of the bag, and the polymer strips of the braid extending in the longitudinal direction of the bag and in the transverse direction of the bag may in particular also have substantially the same width.

Die Eckschweißnähte sind zweckmäßig 2 mm bis 10 mm breit, wobei die Rasterung 10 bis 500 Schweißpunkte bezogen auf eine Fläche von 100 mm2 umfassen kann. Die Schweißpunkte der Eckschweißnähte sind vorzugsweise auf parallelen Linien angeordnet, die unter einem Winkel von 45° zur Längserstreckung der Eckschweißnähte ausgerichtet sind. Auf jeder Linie sind dabei mindestens drei Schweißpunkte in äquidistanten Abständen nebeneinander angeordnet.The corner welds are expediently 2 mm to 10 mm wide, wherein the grid can include 10 to 500 weld points based on an area of 100 mm 2 . The welds of the corner welds are preferably arranged on parallel lines, which are aligned at an angle of 45 ° to the longitudinal extent of the Eckschweißnähte. On each line at least three welds are arranged at equidistant intervals next to each other.

Der Kunststoffgewebeverbund ist üblicherweise aus polyolefinischen Komponenten gefertigt, wobei die Polymerfolie an der Beutelaußenseite vorzugsweise eine Polypropylenfolie ist und insbesondere aus einem biaxial orientierten Polypropylen (BOPP) besteht. Alternativ kann die Polymerfolie an der Beutelaußenseite auch aus einem Polyester oder Polyamid (OPET, OPA) bestehen. Das Gewebe an der Beutelinnenseite weist monoaxial verstreckte Polymerbändchen auf, die miteinander verwebt sind und oberflächlich verschweißt sein können. Das Gewebe weist dann Orientierungen in Längs- und Querrichtung auf.The plastic fabric composite is usually made of polyolefinic components, wherein the polymer film on the outside of the bag is preferably a polypropylene film and in particular consists of a biaxially oriented polypropylene (BOPP). Alternatively, the polymer film on the outside of the bag can also consist of a polyester or polyamide (OPET, OPA). The fabric on the inside of the bag has monoaxially drawn polymer ribbons which are woven together and can be welded on the surface. The fabric then has orientations in the longitudinal and transverse directions.

Der untere Rand der Frontwand, der untere Rand der zur Frontwand benachbarten Flanke der Seitenfalten, der untere Rand der zur Rückwand benachbarten Flanke der Seitenfalten und der untere Rand der Rückwand sind zweckmäßig fächerförmig zueinander versetzt, so dass die entlang der Bodenfalte umgefalteten Lagen des Kunststoffgewebeverbundes jeweils einen Abschnitt aufweisen, der unmittelbar an der Rückwand anliegt und mit der Rückwand vorzugsweise verklebt ist. Auf diese Weise erhält der Seitenfaltenbeutel eine stabile Bodenfläche, die nach der Befüllung des Seitenfaltenbeutels eine im Wesentlichen ebene und standfeste Bodenfläche bildet. Durch Verwendung eines Kunststoffgewebeverbundmaterials eignet sich der erfindungsgemäße Seitenfaltenbeutel für große Gebinde und zur Verpackung von Schüttgut mit einem großen Schüttgewicht.The lower edge of the front wall, the lower edge of the edge of the side folds adjacent to the front wall, the lower edge of the edge of the side folds adjacent to the rear wall and the lower edge of the rear wall are expediently offset in a fan-shaped manner, so that the layers of the plastic fabric composite folded over along the bottom fold respectively have a portion which rests directly on the rear wall and is preferably glued to the rear wall. In this way, the gusseted bag receives a stable bottom surface, which forms a substantially flat and stable bottom surface after filling the gusseted bag. By using a plastic fabric composite material, the gusseted bag according to the invention is suitable for large containers and for packaging bulk material with a high bulk density.

Die Fig. 1 und 2 zeigen einen flachgelegten Seitenfaltenbeutel mit einer Frontwand 1, einer Rückwand 2 und zwischen der Frontwand und der Rückwand angeordneten Seitenfalten 3, die durch Faltkanten 4 mit der Frontwand 1 und der Rückwand 2 verbunden sind. Der Seitenfaltenbeutel wird aus einer ebenen Materialbahn durch Falten geformt. Ein Überlappungsbereich 5, der im Ausführungsbeispiel an der Rückwand 2 angeordnet ist, ist durch eine Verklebung verschlossen. An seinem oberen Ende ist der Seitenfaltenbeutel offen und kann in Abfüllanlagen mit einem schuttfähigen Füllgut befüllt werden. An seinem unteren Ende ist der Seitenfaltenbeutel verschlossen, wobei das verschlossene Ende bei einer Befüllung des Seitenfaltenbeutels eine ebene Bodenfläche bildet. Die Bodenfläche wird dadurch gebildet, dass ein Abschnitt 6 der Frontwand sowie Seitenfaltenabschnitte 7, die zwischen dem Abschnitt 6 der Frontwand 1 und der Rückwand 2 angeordnet sind, unter Bildung einer Bodenfalte 8 auf die Rückwand 2 umgefaltet und mit der Rückwand 2 verbunden werden.The Fig. 1 and 2 show a flattened gusseted bag with a front wall 1, a rear wall 2 and arranged between the front wall and the rear wall gussets 3, by folding edges 4 with the front wall 1 and the rear wall 2 are connected. The gusseted bag is formed from a flat sheet of material by folding. An overlap region 5, which is arranged in the exemplary embodiment on the rear wall 2, is closed by a bond. At its upper end, the gusseted bag is open and can be filled in bottling plants with a pourable filling material. At its lower end, the gusseted bag is closed, wherein the closed end forms a flat bottom surface when filling the gusseted bag. The bottom surface is formed by a portion 6 of the front wall and gusset portions 7, which are arranged between the portion 6 of the front wall 1 and the rear wall 2, folded over to form a bottom fold 8 on the rear wall 2 and connected to the rear wall 2.

Damit sich die Bodenfläche besser ausformt, wenn der Seitenfaltenbeutel befüllt wird, sind Eckschweißnähte 9 vorgesehen, die sich von einer äußeren Faltkante 4 an Längsseiten der Front- oder Rückwand 1, 2 unter einem schrägen Winkel in Richtung der Bodenfalte 8 erstrecken. Die Eckschweißnähte 9 können mit der Bodenfalte 8 einen Winkel α zwischen 30° und 60° einschließen. Im Ausführungsbeispiel und gemäß einer bevorzugten Ausführung der Erfindung begrenzen die Eckschweißnähte 9 mit der Bodenfalte 8 und einer randseitigen Faltkante 4 jeweils eine gleichschenklige Dreieckfläche.Thus, the bottom surface forms better when the side gusseted bag is filled, Eckschweißnähte 9 are provided extending from an outer folding edge 4 on the longitudinal sides of the front or rear wall 1, 2 at an oblique angle in the direction of the bottom fold 8. The Eckschweißnähte 9 may include with the bottom fold 8 an angle α between 30 ° and 60 °. In the exemplary embodiment and according to a preferred embodiment of the invention, the corner weld seams 9 bound with the bottom fold 8 and a marginal folding edge 4 each have an isosceles triangular surface.

Der in den Figuren dargestellte Seitenfaltenbeutel ist aus einem Kunststoffgewebeverbund gefertigt. Der Kunststoffgewebeverbund ist zumindest zweilagig ausgebildet und weist eine Polymerfolie 10 an der Beutelaußenseite sowie ein mit der Polymerfolie 10 verbundenes Gewebe 11 aus Polymerbändchen 12, 13 an der Beutelinnenseite auf. Die Polymerfolie 10 ist mit dem Gewebe 11 fest verklebt. Der Kunststoffgewebeverbund ist beispielsweise aus polyolefinischen Komponenten gefertigt.The gusseted bag shown in the figures is made of a plastic fabric composite. The plastic fabric composite is formed at least two layers and has a polymer film 10 on the outside of the bag and a bonded to the polymer film 10 fabric 11 of polymer tapes 12, 13 on the inside of the bag. The polymer film 10 is firmly bonded to the fabric 11. The plastic fabric composite is made for example of polyolefinic components.

Aus Fig. 3 geht hervor, dass das Gewebe 11 aus einem Geflecht aus bändchenförmigen Polymerstreifen 12, 13 besteht, wobei die Polymerstreifen 12 in Beutellängsrichtung und die Polymerstreifen 13 in Beutelquerrichtung beispielsweise eine Breite zwischen 2 mm und 5 mm aufweisen können. Im Ausführungsbeispiel haben die sich in Beutellängsrichtung und in Beutelquerrichtung erstreckenden Polymerstreifen 12, 13 des Geflechtes im Wesentlichen dieselbe Breite.Out Fig. 3 It can be seen that the fabric 11 consists of a network of ribbon-shaped polymer strips 12, 13, wherein the polymer strips 12 in the bag longitudinal direction and the polymer strips 13 in the bag transverse direction, for example, a width between 2 mm and 5 mm. In the exemplary embodiment, the polymer strips 12, 13 of the braid extending in the longitudinal direction of the bag and in the transverse direction of the bag have substantially the same width.

Die beutelinnenseitige Gewebefläche lässt sich nicht gut siegeln. Es wären hohe Siegeltemperaturen notwendig, wobei die Gefahr bestünde, dass Orientierungen in den Polymerbändchen 12, 13 zerstört würden. Die Eckschweißnähte 9 werden erfindungsgemäß durch Ultraschallschweißen erzeugt und weisen eine durch Ultraschallschweißen erzeugte Struktur mit einer Rasterung aus einer Vielzahl hintereinander und nebeneinander angeordneter Schweißpunkte 14 auf. Die Schweißpunkte 14 verbinden die beutelinnenseitige Gewebefläche der Seitenfalten 3 mit der benachbarten Gewebefläche der Frontwand 1 oder Rückwand 2. Im Rahmen der Erfindung liegt es auch, dass die durch Ultraschallschweißen erzeugte Struktur der Eckschweißnähte als eine Anordnung aus linienförmigen Schweißstellen besteht, wobei die Schweißlinien beispielsweise parallel ausgerichtet sind oder sich kreuzen.The bag-inside tissue surface does not seal well. High sealing temperatures would be necessary, with the risk that orientations in polymer ribbons 12, 13 would be destroyed. The corner welds 9 are produced according to the invention by ultrasonic welding and have a structure produced by ultrasonic welding with a grid of a plurality of successively arranged and juxtaposed welds 14. The welding points 14 connect the bag inner side fabric surface of the gussets 3 with the adjacent fabric surface of the front wall 1 or rear wall 2. Within the scope of the invention is also that the generated by ultrasonic welding structure of the corner welds as an array of linear welds, the weld lines, for example, parallel are aligned or intersect.

Das Verfahrensprinzip zur Herstellung der Eckschweißnähte 9 durch Ultraschallschweißen ist in Fig. 5 dargestellt. Mit Hilfe eines Generators wird hochfrequenter Wechselstrom erzeugt und zu einem Ultraschallwandler übertragen, der daraus eine mechanische Ultraschallfrequenz erzeugt. Die hochfrequenten mechanischen Schwingungen einer Sonotrode 15 werden unter Druck auf die zu verbindenden Polymerflächen übertragen. Die Schwingungen verursachen beim Ultraschallschweißen Molekular- und Grenzflächenreibung in der Fügezone. Dabei entsteht die zum Schweißen notwendige Wärme, wobei das Polymermaterial an den Schweißpunkten 14 plastifiziert wird. Gemäß der Darstellung in Fig. 5 greift ein Widerlager 16 für die Sonotrode 15 randseitig in die gespreizten Seitenfalten 3 ein. Die Ultraschallsiegelung hat den Vorteil, dass die Schweißzeiten kurz sind und die thermische Energie weitestgehend in den Kontaktbereichen entsteht, wodurch andere Laminatbereiche und insbesondere die orientierten Polymerbändchen 12, 13 des Gewebes 11 mit weniger Wärme belastet werden.The process principle for producing the corner welds 9 by ultrasonic welding is in Fig. 5 shown. With the help of a generator high-frequency alternating current is generated and transmitted to an ultrasonic transducer, which generates a mechanical ultrasonic frequency. The high-frequency mechanical vibrations of a sonotrode 15 are transferred under pressure to the polymer surfaces to be joined. The vibrations cause ultrasonic and interfacial friction in the joining zone during ultrasonic welding. This creates the heat necessary for welding, with the polymer material is plasticized at the weld points 14. As shown in Fig. 5 engages an abutment 16 for the sonotrode 15 at the edge in the spread gussets 3 a. The ultrasonic sealing has the advantage that the welding times are short and the thermal energy largely arises in the contact areas, whereby other laminate areas and in particular the oriented polymer tapes 12, 13 of the fabric 11 are loaded with less heat.

Die Eckschweißnähte 9 weisen entsprechend der Darstellung in Fig. 4 jeweils eine Breite zwischen 2 mm und 10 mm auf, wobei die Rasterung zweckmäßig 10 bis 500 Schweißpunkte 14 bezogen auf eine Fläche von 100 mm2 umfasst. Im Ausführungsbeispiel ist die Eckschweißnaht 9 ca. 4 mm breit und setzt sich aus ca. 100 Schweißpunkten bezogen auf eine Fläche von 100 mm2 zusammen. Der Darstellung in Fig. 4 ist auch zu entnehmen, dass die Schweißpunkte 14 der Eckschweißnähte 9 auf parallelen Linien 17 angeordnet sind, die unter einem Winkel β von 45° zur Längserstreckung der Eckschweißnähte 9 ausgerichtet sind. Auf jeder Linie 17 sind mindestens drei Schweißpunkte 14 in äquidistanten Abständen nebeneinander angeordnet.The corner welds 9, as shown in FIG Fig. 4 each have a width between 2 mm and 10 mm, wherein the screening suitably 10 to 500 weld points 14 based on an area of 100 mm 2 includes. In the exemplary embodiment, the Eckschweißnaht 9 is about 4 mm wide and is composed of about 100 welds based on an area of 100 mm 2 together. The representation in Fig. 4 It can also be seen that the welding points 14 of the corner welds 9 are arranged on parallel lines 17, which are aligned at an angle β of 45 ° to the longitudinal extent of the corner welds 9. On each line 17 at least three welds 14 are arranged at equidistant intervals next to each other.

Im Ausführungsbeispiel der Fig. 8 ist in mindestens einem durch eine Eckschweißnaht 9 begrenzten dreieckförmigen Beutelabschnitt 7' eine Entlüftungsöffnung 24 angeordnet. Zwischen dem mit der Entlüftungsöffnung 24 versehenen Beutelabschnitt 7' und dem Füllraum des Seitenfaltenbeutels ist ein Luftaustausch gewährleistet. Der Luftaustausch ist durch Pfeile angedeutet. Im Ausführungsbeispiel ist der Luftaustausch möglich, weil die Eckschweißnaht 9 einen Abstand zur Bodenfalte 8 und zur Faltkante 4 an der Längsseite des Beutels einhält. Alternativ oder zusätzlich kann die Eckschweißnaht beispielsweise unterbrochen sein, um den Luftaustausch zwischen dem dreieckförmigen Beutelabschnitt 7' und dem Füllraum des Seitenfaltenbeutels zu gewährleisten oder zu fördern.In the embodiment of Fig. 8 is in at least one limited by a corner weld 9 triangular bag section 7 'a vent opening 24 is arranged. Between the provided with the vent opening 24 bag portion 7 'and the filling space of the gusseted bag an air exchange is ensured. The air exchange is indicated by arrows. In the exemplary embodiment, the air exchange is possible because the corner weld seam 9 maintains a distance from the bottom fold 8 and the folding edge 4 at the longitudinal side of the bag. Alternatively or additionally, the corner weld may be interrupted, for example, to prevent the air exchange between the To ensure or promote triangular bag portion 7 'and the filling space of the gusseted bag.

Die Eckschweißnähte 9 bewirken beim Abfüllen des Seitenfaltenbeutels eine gute Bodenausformung. Nach der Befüllung und dem Verschluss seines oberen Endes bildet der Seitenfaltenbeutel eine im Wesentlichen quaderförmige Verpackung mit einer ebenen standfesten Bodenfläche, wie dies in Fig. 6 dargestellt ist.The Eckschweißnähte 9 cause when filling the gusseted bag a good Bodenausformung. After filling and closure of its upper end, the gusseted bag forms a substantially parallelepipedic package with a flat, stable bottom surface, as shown in FIG Fig. 6 is shown.

Der aus einem Kunststoffgewebeverbund gefertigte Seitenfaltenbeutel kann zur Verpackung von schüttfähigen Füllgütern wie pelletierte Tiernahrung, Einstreu für Tiere oder ähnliche Materialien eingesetzt werden und ist als Sack insbesondere für Großgebinde geeignet, die ein erhebliches Füllvolumen und ein erhebliches Füllgewicht aufweisen. Abgesehen davon, dass die Verpackung eine durch die Eckschweißnähte 9 gut ausgeformte ebene Bodenfläche aufweist, muss die Bodenfläche bei der Befüllung und bei der Handhabung des Sacks einer großen Belastung standhalten. Da die Gewebeflächen an der Beutelinnenseite nicht siegelfähig sind, werden die Materiallagen vorzugsweise miteinander verklebt. Im Hinblick auf eine feste Klebeverbindung ist es zweckmäßig, wenn die miteinander zu einer Bodenfläche zu verklebenden Folienlagen ein Kantenprofil mit der in Fig. 7 dargestellten Kontur aufweisen. Der Darstellung in Fig. 7, die einen Blick auf die Rückwand 2 zeigt, ist zu entnehmen, dass der untere Rand 18 der Frontwand 1, der untere Rand 19 der zur Frontwand 1 benachbarten Flanke 20 der Seitenfalten 3, der untere Rand 21 der zur Rückwand 2 benachbarten Flanke 22 der Seitenfalten 3 und der untere Rand 23 der Rückwand 2 fächerförmig zueinander versetzt sind. Dadurch wird erreicht, dass die entlang der Bodenfalte 8 umgefalteten Lagen des Kunststoffgewebeverbundes jeweils einen Abschnitt aufweisen, der unmittelbar an der Rückwand 2 anliegt und mit der Rückwand 2 verklebt oder verschweißt ist.The gusseted bag made of a plastic fabric composite can be used for packaging bulk goods such as pelleted pet food, litter for animals or similar materials and is suitable as a bag especially for large containers, which have a considerable filling volume and a considerable filling weight. Apart from the fact that the packaging has a well-formed by the Eckschweißnähte 9 flat bottom surface, the bottom surface must withstand during loading and handling of the bag a large load. Since the tissue surfaces on the inside of the bag are not sealable, the material layers are preferably glued together. With regard to a fixed adhesive connection, it is expedient if the film layers to be bonded together to form a bottom surface have an edge profile with the in Fig. 7 have shown contour. The representation in Fig. 7 , which shows a view of the rear wall 2, it can be seen that the lower edge 18 of the front wall 1, the lower edge 19 of the front wall 1 adjacent flank 20 of the gussets 3, the lower edge 21 of the back wall 2 adjacent flank 22 of Gussets 3 and the lower edge 23 of the rear wall 2 are fan-shaped offset from one another. It is thereby achieved that the folded along the bottom fold 8 layers of plastic fabric composite each having a portion which rests directly on the rear wall 2 and is glued or welded to the rear wall 2.
