Description

Die Erfindung betrifft einen Standbodenbeutel mit zwei Sei­tenwänden, die im Randbereich entlang ihren Seitenkanten un­ter Bildung abstehender Seitenrandstreifen stoffschlüssig verbunden sind.The invention relates to a stand-up pouch with two side walls which are integrally connected in the edge region along their side edges to form protruding side edge strips.

Ein Standbodenbeutel bzw. Nachfüllbeutel dieser Art ist aus dem DE-GM 88 07 593 bekannt. Mit einem derartigen Beutel wer­den Reinigungs- oder Waschflüssigkeiten aber auch Pulver zum Nachfüllen entsprechender Originalbehälter, insbesondere Fla­schen, angeboten. Als Standfläche des bekannten Nachfüllbeu­tels kann dessen unterer umfangsrand dienen, die Seitenwände des Beutels werden am unteren Ende durch einen faltbaren Bo­den miteinander verbunden. Die Kanten des Bodens können der­art mit den unteren Kanten der Seitenwände stoffschlüssig verbunden, insbesondere verschweißt, werden, daß die Kanten als versteifte Ränder nach unten abstehen und eine Art Stand­kante bilden.A stand-up pouch or refill pouch of this type is known from DE-GM 88 07 593. With such a bag, cleaning or washing liquids but also powders for refilling corresponding original containers, in particular bottles, are offered. The lower peripheral edge of the known refill bag can serve as a standing surface, the side walls of the bag are connected to one another at the lower end by a foldable base. The edges of the floor can be integrally connected, in particular welded, to the lower edges of the side walls in such a way that the edges project downward as stiffened edges and form a kind of standing edge.

Zum Erleichtern des Umfüllens des Inhalts des Standbodenbeu­tels wird an diesen eine zylindrische Tülle angeformt, die über den oberen Beutelrand - also dem Beutelboden gegenüber­liegend - übersteht. Vorzugsweise wird eine Tüllenkante als gradlinige Fortsetzung eines der an den Seitenwänden vorgese­henen Beutelränder ausgebildet. Dadurch wird das Ausschütten bzw. Umfüllen des Beutelinhalts sehr vereinfacht.To facilitate the filling of the contents of the stand-up pouch, a cylindrical spout is molded onto it protrudes over the upper edge of the bag - i.e. opposite the bag bottom. A spout edge is preferably formed as a straight continuation of one of the bag edges provided on the side walls. This makes it very easy to pour out or transfer the contents of the bag.

Die Materialauswahl der Standbodenbeutel wird so getroffen, daß auf engstem Raum möglichst viel Volumen an Nachfüllsub­stanz untergebracht werden kann. Das erfordert eine erheb­liche Flexibilität des einzelnen Standbodenbeutels. Die für das Lagern einer Vielzahl von Standbodenbeuteln gewünschte Flexibilität wird jedoch störend, wenn ein einzelner Beutel in einen Behälter hinein auszuschütten oder, insbesondere nach teilweisem Entleeren, aufzustellen ist.The choice of materials for the stand-up pouches is made in such a way that as much volume of refill substance as possible can be accommodated in the smallest space. This requires considerable flexibility for the individual stand-up pouch. The flexibility required for storing a large number of stand-up pouches becomes disruptive, however, when a single pouch has to be poured into a container or, especially after partial emptying, to be set up.

Der Erfindung liegt die Aufgabe zugrunde, die Standfestigkeit eines Standbodenbeutels noch weiter zu erhöhen und zugleich die Flexibilität des Beutels für das Lagern zu erhalten. Die erfindungsgemäße Lösung besteht für den eingangs genannten Standbodenbeutel mit an den Seitenkanten unter Bildung seit­lich abstehender Beutelränder stoffschlüssig miteinander ver­bundenen Seitenwänden darin, daß die Seitenrandstreifen durch ein dreidimensionales Profil versteift sind.The invention has for its object to increase the stability of a stand-up pouch even further while maintaining the flexibility of the pouch for storage. The solution according to the invention for the stand-up pouch mentioned at the outset, with side walls integrally connected to one another at the side edges to form laterally projecting bag edges, is that the side edge strips are stiffened by a three-dimensional profile.

Durch die erfindungsgemäße geometrische Verformung der seit­lich abstehenden Beutelränder - also durch das Hinzufügen ei­ner Dimension senkrecht zur Randstreifenfläche - wird eine zusätzliche Formstabilität der ohnehin zur Biegefestigkeit des Standbodenbeutels erheblich beitragenden, nach außen abstehenden Randstreifen erreicht.The geometric deformation according to the invention of the laterally projecting bag edges - that is to say by adding a dimension perpendicular to the edge strip surface - achieves an additional dimensional stability of the edge strips which in any case contribute significantly to the bending strength of the stand-up pouch and project outwards.

Gemäß weiterer Erfindung wird es bevorzugt, wenn die Seiten­ randstreifen ein sich in ihrer Längsrichtung erstreckendes, versteifendes Profil aufweisen. Durch diese Erhöhung von Bie­gesteifigkeit und Biegemoment in axialer Richtung, das heißt in Richtung parallel zu der Längserstreckung der Seitenrän­der, wird die Gestaltsteifigkeit des ganzen Beutels derart erhöht, daß der Beutel auch bei teilweiser Füllung noch bis hin zur aufrecht stehenden Ausgießtülle standfest bleibt. Wenn die Seitenwände und sonstigen Teile des Standbodenbeutels aus Folie bestehen, werden zum stoffschlüs­sigen Verbinden der Kanten und Randstreifen bevorzugt Schweißnähte vorgesehen. Der Gegenstand der Erfindung kann dann als eine Art Formschweißen zum Erzeugen von sich paral­lel zur Längsrichtung der Randstreifen erstreckenden gerunde­ten und/oder kantigen Versteifungsrippen beschrieben werden.According to another invention, it is preferred if the sides edge strips have a stiffening profile extending in their longitudinal direction. This increase in bending stiffness and bending moment in the axial direction, that is, in the direction parallel to the longitudinal extent of the side edges, increases the structural rigidity of the entire bag in such a way that the bag remains stable even with partial filling up to the upright pouring spout. If the side walls and other parts of the stand-up pouch are made of film, weld seams are preferably provided for the integral connection of the edges and edge strips. The object of the invention can then be described as a type of shape welding for producing rounded and / or angular stiffening ribs extending parallel to the longitudinal direction of the edge strips.

Eine erfindungsgemäße Erhöhung der Gestaltsteifigkeit des Beutels durch Verbesserung der Dimensionsstabilität des Beutelrandes wird gemäß weiterer Erfindung schon dadurch er­zielt, daß das Profil aus mindestens einer in der Längsrich­tung verlaufenden Faltlinie besteht. Das bedeutet also, daß eine Gestaltsteifigkeit schon zu erreichen ist, wenn jeder der Beutelrandstreifen - im Bereich der stoffschlüssigen Verbindung - einmal um etwa 90° geknickt wird. Letztlich geht es also nur darum, daß der streifenförmig seitlich vom Beutel abstehende Rand dreidimensional gemacht wird. In diesem Sinne wird die Stabilität noch größer, wenn in bevorzugter Weise das Profil im Schnitt senkrecht zu der Längsrichtung einen ein- oder mehrfachen Halbkreis-, Dreieck- oder Rechteck-Quer­schnitt besitzt. Selbstverständlich wird die Gestaltsteifig­keit umso nachhaltiger verbessert, je ausgeprägter und um­fangsreicher der dreidimensionale Bereich gleichermaßen mit der Wirkung von Versteifungsrippen in bzw. an der Beutelkante ist.An increase in the stiffness of the bag according to the invention by improving the dimensional stability of the bag edge is achieved according to another invention in that the profile consists of at least one fold line running in the longitudinal direction. This means that a structural rigidity can be achieved if each of the edge strips of the bag - in the area of the integral connection - is bent once by about 90 °. Ultimately, it is only a question of making the edge protruding in strips from the bag in three dimensions. In this sense, the stability becomes even greater if the profile preferably has a single or multiple semicircular, triangular or rectangular cross section in section perpendicular to the longitudinal direction. Of course, the stiffness is improved the more sustainably, the more pronounced and extensive the three-dimensional area with the effect of stiffening ribs in or on the edge of the bag is.

Gemäß weiterer Erfindung wird ein versteifendes Profil außer an den Seitenkanten auch an der Unterkante des Beutels vorge­sehen. Eine Versteifung der unteren Randstreifen des Beutel­bodens ist für die Standfestigkeit des ganzen Beutels wich­tig, weil der Beutelboden gewissermaßen als Fundament der Seitenflächen, insbesondere aber auch der versteiften Seitenrandstreifen des Beutels anzusehen ist. Daher ist es im Bodenbereich des Standbodenbeutels zum Erhöhen der Standfe­stigkeit und Tragfähigkeit besonders vorteilhaft, die Flä­chensteifigkeit zu verstärken. Gemäß weiterer Erfindung ist es auch günstig, wenn am Boden im unteren Randstreifen sich senkrecht zur Auflagefläche erstreckende Versteifungsrippen vorgesehen werden.According to another invention, a stiffening profile is provided on the lower edge of the bag in addition to the side edges. A stiffening of the lower edge strips of the bag bottom is important for the stability of the entire bag, because the bag bottom is to a certain extent the foundation of the side surfaces, but in particular also the stiffened side edge strips of the bag. It is therefore particularly advantageous to increase the surface rigidity in the bottom area of the stand-up pouch to increase the stability and load-bearing capacity. According to a further invention, it is also favorable if stiffening ribs extending perpendicular to the contact surface are provided on the bottom edge strip.

Gemäß noch weiterer Erfindung kann sich das versteifende Pro­fil der Seitenrandstreifen in den Bereich eines an der Beu­teloberseite vorgesehenen oberen Randstreifens hineiner­strecken. Dort verbleibt dann als Öffnung lediglich eine Aus­gießtülle, so daß der demgemäß fast rundum laufende versteif­te Randstreifen eine Art Versteifungsrahmen des Standboden­beutels bildet.According to yet another invention, the stiffening profile of the side edge strips can extend into the area of an upper edge strip provided on the top of the bag. There then remains only an pouring spout as an opening, so that the stiffened edge strip running almost all around accordingly forms a type of stiffening frame for the stand-up pouch.

Anhand der schematischen Darstellung von Ausführungsbeispie­len werden Einzelheiten der Erfindung erläutert. Es zeigen:

  • Fig. 1 einen Standbodenbeutel in perspekti­vischer Darstellung;
  • Fig. 2 und 3 vertikale Schnitte durch einen einteili­gen und einen dreiteiligen Beutel;
  • Fig. 4 bis 8 Ausführungsbeispiele von dreidimensional versteiften Beutelrandstreifen; und
  • Fig. 9 einen gefüllten Standbodenbeutel.
Details of the invention are explained on the basis of the schematic representation of exemplary embodiments. Show it:
  • Figure 1 is a stand-up pouch in perspective.
  • Figures 2 and 3 vertical sections through a one-piece and a three-piece bag.
  • 4 to 8 embodiments of three-dimensionally stiffened bag edge strips; and
  • Fig. 9 a filled stand-up pouch.

Der insgesamt mit 1 bezeichnete Standbodenbeutel nach Fig. 1 besteht im wesentlichen aus zwei Seitenwänden 2 und 3 mit Einfülltülle 4 und faltbarem Boden 5. Die Seitenwände bestehen aus zumindest an den Seitenkanten 6 und an der Kopf­kante 7 miteinander verschweißten Kunststoffolien. Der Boden 5 ist bei dem einteiligen Beutel nach Fig. 2 einteilig mit den Seitenwänden 2 und 3 verbunden. Bei der dreiteiligen Aus­führung des Beutels 1 nach Fig. 3 werden die unteren Kanten, also die Bodenkanten 8 der Seitenwände 2 und 3 mit den ent­sprechenden Bodenrändern 9 des ursprünglich gesonderten Bo­dens 5 verschweißt.1 consists essentially of two side walls 2 and 3 with a filling spout 4 and foldable bottom 5. The side walls consist of plastic foils welded to one another at least on the side edges 6 and on the top edge 7. In the one-piece bag according to FIG. 2, the base 5 is connected in one piece to the side walls 2 and 3. 3, the lower edges, that is to say the bottom edges 8 of the side walls 2 and 3, are welded to the corresponding bottom edges 9 of the originally separate bottom 5.

An dem perspektivisch dargestellten Standbodenbeutel nach Fig. 1 werden die Seitenwände 2 und 3 im Randbereich ihrer Seitenkanten 6, ihrer Kopfkanten 7 und ihrer Bodenkanten 8 miteinander bzw. mit dem Bodenrändern 9 des Bodens 5 zu ent­sprechenden Randstreifen 10, 11 bzw. 12 verschweißt oder auf andere Weise stoffschlüssig verbunden. Die seitlichen Rand­streifen 10 bzw. 11 stehen in einer Ebene (parallel zur Zei­chenebene von Fig. 1) seitlich bzw. nach oben ab. Die unteren Randstreifen 12 sind in der Ebene der jeweiligen Seitenwand 2 und 3 vertikal nach unten gerichtet.1, the side walls 2 and 3 in the edge region of their side edges 6, their top edges 7 and their bottom edges 8 are welded to one another or to the bottom edges 9 of the bottom 5 to form corresponding edge strips 10, 11 and 12, respectively otherwise cohesively connected. The lateral edge strips 10 and 11 protrude laterally or upwards in a plane (parallel to the drawing plane of FIG. 1). The lower edge strips 12 are in the plane of the respective side wall 2 and 3 directed vertically downwards.

Zu dem Standbodenbeutel 1 gehört außerdem die Tülle 4, die im wesentlichen zylindrisch sein soll und die aus Verlängerungs­stücken 13 der Seitenwände 2, 3 bestehen kann. Die Tülle 4 kann ebenso wie der ganze Standbodenbeutel 1 mit Hilfe der in den Bereich der Tülle hinein verlängerten, versteifenden Randstreifen 10 bzw. 11 in ihrer Gestalt stabilisiert werden, derart, daß die zur Tülle 4 gehörige Ausgießöffnung 14 bei teilweise oder ganz gefülltem Beutel 1 stets aufrechtsteht und so aufgespannt bleibt, daß ein Ausgießen fast so wie bei einer starre Wände aufweisenden Flasche mög­lich ist.The stand-up pouch 1 also includes the spout 4, which should be essentially cylindrical and which can consist of extension pieces 13 of the side walls 2, 3. Like the entire stand-up pouch 1, the shape of the spout 4 can be stabilized with the aid of the stiffening edge strips 10 and 11, which are extended into the area of the spout, such that the pouring opening 14 belonging to the spout 4 when the bag 1 is partially or completely filled always stands upright and remains so open that pouring is almost as possible as with a bottle with rigid walls.

Nach Vorstehendem bilden die Randstreifen 10, 11 und 12 das wesentliche Versteifungsgerüst des Standbodenbeutels 1. Die Gestaltsteifigkeit des Standbodenbeutels wird dadurch erhöht, daß zumindest an den Seitenkanten 6 in den nach außen vorste­henden Seitenrandstreifen 10 ein sich in Langsrichtung 15 der Randstreifen 10 bis 12 erstreckendes, versteifendes dreidi­mensional-geometrisches Profil vorgesehen wird.According to the above, the edge strips 10, 11 and 12 form the essential stiffening structure of the stand-up pouch 1. The structural rigidity of the stand-up pouch is increased by the fact that, at least on the side edges 6 in the outwardly projecting side edge strips 10, a lengthwise 15 of the edge strips 10 to 12 extends, stiffening three-dimensional geometric profile is provided.

Dieses Profil besteht nach Fig. 4 aus einer L-Knickung längs einer parallel zu der Längsrichtung 15 verlaufenden Faltlinie 16. Anstelle einer einzigen solchen Faltlinie 16 kann nach Fig. 5 auch eine ebenfalls in der Längsrichtung 15 (Fig. 1) des jeweiligen Randstreifens verlaufende Rechteck-Faltung 17 vorgesehen werden. Eine weitere Möglichkeit besteht nach Fig. 6 darin, eine Faltung mit Zieharmonika-Querschnitt, also eine Dreieck-Faltung 18, vorzusehen. Gute Versteifungen lassen sich auch erzielen, wenn der jeweilige Randstreifen als Halbkreisfaltung nach Fig. 7 oder als Schlangenlinienfaltung 20 nach Fig. 8 ausgebildet wird. Letztlich wird also das ur­sprünglich flächige, das heißt zweidimensionale, Profil der Randstreifen durch Faltungen oder Biegungen, die wie verstei­fende "Rippen" wirken, dreidimensional gemacht.According to FIG. 4, this profile consists of an L-bend along a fold line 16 running parallel to the longitudinal direction 15. Instead of a single fold line 16 of this type, according to FIG. 5, one can also run in the longitudinal direction 15 (FIG. 1) of the respective edge strip Rectangular fold 17 are provided. Another possibility according to FIG. 6 is to provide a folding with an accordion cross section, that is to say a triangular folding 18. Good stiffening can also be achieved if the respective edge strip as a semicircular fold according to FIG. 7 or as a serpentine fold 20 is formed according to FIG. 8. Ultimately, the originally flat, that is to say two-dimensional, profile of the edge strips is made three-dimensional by means of folds or bends which act like stiffening "ribs".

Für eine gute Standfestigkeit des Bodens ist es schließlich förderlich, wenn der Boden nach Fig. 9 versteifende Rippen 21 aufweist, die dort innerhalb der Randstreifen 12 in etwa senkrecht zu der Längsrichtung 15 des Bodenrandes 8 und in etwa vertikal verlaufen.For a good stability of the floor, it is finally beneficial if the floor according to FIG. 9 has stiffening ribs 21, which run there within the edge strips 12 approximately perpendicular to the longitudinal direction 15 of the floor edge 8 and approximately vertically.

Bei bisher üblichen Standbodenbeuteln bilden sich seitliche Einfaltungen, sofern der Beutel mit einer Ausgießtülle verse­hen ist. Dieser Effekt beruht auf dem Ausbauchen des Beutels. Um diesen Nachteil zu vermeiden, werden erfindungsgemäß die seitlichen Randstreifen 10 durch die oben genannte dreidimen­sionale Verformung versteift. Da aber auch der erfindungsge­mäße Beutel beim Füllen ausbaucht, zieht er die für das Aus­bauchen benötigte Folienfläche aus dem Kopfbereich ab, wo­durch es zu einem in Fig. 9 angedeuteten Einfaltungsbereich 23 angrenzend an die Schulter 22 kommt. Herstellungstechnisch bedingt lassen sich also Einfaltungen des Beutels beim Füllen nicht vermeiden. Durch die erfindungsgemäßen Maßnahmen wird jedoch erreicht, daß die Einfaltung des Beutels definiert in den oberen Bereich angrenzend an die Schulter 22 verschoben wird und demgemäß die Standfestigkeit des Beutels nicht mehr beeinträchtigten kann.In the case of stand-up pouches which have been customary to date, side folds form if the pouch is provided with a pouring spout. This effect is due to the bulging of the bag. In order to avoid this disadvantage, the lateral edge strips 10 are stiffened according to the invention by the three-dimensional deformation mentioned above. However, since the bag according to the invention also bulges when it is filled, it pulls the film surface required for bulging out of the head region, which leads to a fold-in region 23 indicated in FIG. 9 adjacent to the shoulder 22. For manufacturing reasons, folds of the bag cannot be avoided during filling. However, the measures according to the invention ensure that the folding of the bag is shifted in a defined manner into the upper region adjacent to the shoulder 22 and accordingly can no longer impair the stability of the bag.
