Description

"Standbodenbeutel" "Stand-up pouch"
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 Nachfüllbeuteis 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 anstehen 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 circumferential edge can serve as the base of the known refill bag, 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 stand down as stiffened edges and form a kind of standing edge.
Zum Erleichtern des Umfüllens des Inhalts des Standbodenbeutels wird an diesen eine zylindrische Tülle angefόrmt, die über den oberen Beutel rand - also dem Beutel boden gegenüberliegend - übersteht. Vorzugsweise wird eine Tüllenkante als gradlinige Fortsetzung eines der an den Seitenwänden vorgesehenen Beutel ränder ausgebildet. Dadurch wird das Ausschütten bzw. Umfüllen des Beutel inhalts sehr vereinfacht. To make it easier to transfer the contents of the stand-up pouch, a cylindrical spout is warmed to it protrudes over the top edge of the bag - i.e. opposite the bag bottom. Preferably, a spout edge is formed as a straight continuation of one of the edges of the bag provided on the side walls. This makes it very easy to pour or pour the contents of the bag.
Die Material auswahl der Standbodenbeutel wird so getroffen, daß auf engstem Raum möglichst viel Volumen an Nachfüll Substanz 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 material for the stand-up pouches is made in such a way that as much volume as possible of refill substance can be accommodated in the smallest space. This requires considerable flexibility for the individual stand-up pouch. However, the flexibility required for storing a large number of stand-up pouches becomes disruptive 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 anstehender 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 αes 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 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 stoffschlüssi gen 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 foil, weld seams are preferably provided for materially connecting 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 Erhönung der Gestaltsteifigkeit des Beutels durch Verbesserung der Dimensionsstabilität des Beutel randes 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 Beutel randstreifen - im Bereich der stoffschlüssigen Verbindung - einmal um etwa 90º 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 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. 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 longitudinally extending fold line. This means that a structural stiffness can be achieved if each of the bags is edged - in the area of the integral connection - once by approximately 90 °. Ultimately, it is only a matter 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 According to another invention, a stiffening profile is provided on the bottom edge of the bag in addition to the side edges. A stiffening of the lower edge strips of the bag base is important for the stability of the entire bag, because the bag base 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 in the bottom area of the stand-up pouch to increase the stability and load-bearing capacity to increase the surface stiffness. According to a further invention, it is also favorable if stiffening ribs extending perpendicular to the contact surface are provided on the bottom in the lower 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: Details of the invention are explained on the basis of the schematic representation of exemplary embodiments. Show it:
Fig. 1 einen Standbodenbeutel in perspektivischer Darstellung; Figure 1 is a stand-up pouch in perspective.

Fig. 9 einen gefüllten Standbodenbeutel. 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 filler spout 4 and foldable bottom 5. The side walls consist of plastic films welded together at least on the side edges 6 and on the top edge 7. In the one-piece bag according to FIG. 2, the bottom 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 de<"n Boαenrändern 9 des Bodens 5 zu entsprechenden Randstreifen 10, 11 bzw. 12 verschweißt oder auf andere Weise Stoffschlüssig verbunden. Die seitlichen Rancstreifen 10 bzw. 11 stenen 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 with one another or with the bottom edges 9 of the bottom 5 become corresponding edge strips 10, 11 and 12 respectively The lateral rancstrips 10 and 11, respectively, protrude laterally or upwards in a plane (parallel to the plane of the drawing in 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 stabil i si e rt 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. The spout 4, like the entire stand-up pouch 1, can be made stable in shape 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 is partially or completely filled bag 1 always stands up and remains so open that pouring is almost as possible as with a rigid wall bottle.
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 5 in den nach außen vorstehenden Seitenrandstreifen 10 ein sich in Längsrichtung 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 in that, at least on the side edges 5 in the outwardly projecting side edge strips 10, a longitudinally extending 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 alsHalbκreisfaltung nach Fig. 7 oder als Schlangenlinienfaltung 20 nach Fig. 8 ausgebildet wird. Letztlich wird also das ursprünglich flächige, das heißt zwei dimensionale, 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 is used as a semi-circular 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 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. Bezugszeichenliste In the case of stand-up pouches which have been customary to date, lateral folds are formed if the pouch is provided with a pouring spout. This effect is based on 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 results in a fold-in region 23 indicated in FIG. 9 adjacent to the shoulder 22. For manufacturing reasons, folds of the bag during filling cannot be avoided. 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.
