Abstract
Description
Die Erfindung betrifft einen Mehrrandsiegelbeutel mit wenigstens zwei durch eine Siegelnaht fluiddicht voneinander getrennten Kammern, wobei die die Kammern voneinander trennende Siegelnaht unter Einwirkung äußeren Drucks zumindest teilweise aufreißt und eine Fluidverbindung zwischen den getrennten Kammern herstellt.The invention relates to a multi-edge sealed bag with at least two through a sealed seam chambers separated from one another in a fluid-tight manner, the chambers separating the chambers from one another Sealing seam at least partially tears open under the influence of external pressure and a fluid connection between the separate chambers.
Ein derartiger Beutel ist allgemein bekannt, zum Beispiel aus der DE 77 23 214 U1 oder auch DE 34 26 465 A1. Auch aus der WO 95/05327 ist eine entsprechende Konstruktion dargestellt.Such a bag is generally known, for example from DE 77 23 214 U1 or also DE 34 26 465 A1. A corresponding construction is also shown from WO 95/05327.
Bei all den bekannten Konstruktionen muß darauf geachtet werden, dass die die Kammern voneinander trennende Siegelnaht im Vergleich zu den Randnähten eine deutlich geringere Festigkeit aufweist, um sicherzustellen, dass unter Einwirkung äußeren Drucks die die Kammern voneinander trennende Siegelnaht aufreißt und eine Fluidverbindung zwischen den getrennten Kammern herstellt. Die Sicherstellung der vorgenannten Funktion ist herstellungstechnisch aufwendig. Auch lässt die Funktionssicherheit der bekannten Mehrkammerbeutel zu wünschen übrig.In all the known constructions, care must be taken that the chambers sealing seam separating one another is significantly less in comparison to the edge seams Has strength to ensure that the external pressure is exerted on the chambers separating seal seam tears open and a fluid connection between the produces separate chambers. Ensuring the aforementioned function is manufacturing technology consuming. The reliability of the known multi-chamber bags also leaves to be desired.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Mehrkammerbeutel, insbesondere Zweikammerbeutel der eingangs genannten Art zu schaffen, der einfach herzustellen und dennoch funktionssicher ist. The present invention has for its object a multi-chamber bag, in particular To create two-chamber bags of the type mentioned that is easy to manufacture and yet it is reliable.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst, wobei konstruktive Details in den Unteransprüchen beschrieben sind.This object is achieved by the characterizing features of the claim 1 solved, constructional details are described in the subclaims.
Insbesondere wird die Aufgabe durch einen Mehrrandsiegelbeutel mit mindestens zwei durch eine Siegelnaht fluiddicht voneinander getrennten Kammern gelöst, wobei die die Kammern voneinander trennende Siegelnaht unter Einwirkung äußeren Drucks zumindest teilweise aufreißt und eine Fluidverbindung zwischen den getrennten Kammern herstellt, wobei der Beutel eine Vorderwand, eine Rückwand und eine Bodenwand in Form einer W-Falte aufweist und wobei Vorder- und Rückwand einschließlich W-Falte sowohl längs ihrer beiden äußeren Ränder als auch zwischen diesen unter Ausbildung von wenigstens zwei Beutelkammern so miteinander verschweißt oder versiegelt sind, daß die die Kammern voneinander trennende Siegelnaht im Bereich des Zwickels der bodenseitigen W-Falte einen Übergang von vier miteinander verschweißten bzw. versiegelten Folienlagen zu zwei miteinander verschweißten bzw. versiegelten Folienlagen aufweist.In particular, the task is accomplished by a multi-edge sealed bag with at least two a sealed seam fluid-tightly separated from each other, the chambers sealing seam separating one another at least partially under the action of external pressure tears open and creates a fluid connection between the separate chambers, the Bag has a front wall, a rear wall and a bottom wall in the form of a W fold and wherein the front and back walls including the W fold are both along their two outer edges as well as between these to form at least two pouch chambers are so welded or sealed together that the chambers from each other separating sealing seam in the area of the gusset of the bottom W fold a transition from four foil layers welded or sealed together to two welded together or sealed foil layers.
Der wesentliche Kern der Erfindung besteht hierbei in der bodenseitigen W-Faltung. Die Funktionssicherheit des erfindungsgemäßen Beutels ist aus nachfolgend genannten Gründen durch die Siegelung bzw. Verschweißung der zur Herstellung verwendeten Folien im Bereich des Zwickels der W-Falte gewährleistet. In diesem Bereich liegen jeweils vier Lagen übereinander, die miteinander verschweißt bzw. versiegelt werden. Im übrigen liegen nur zwei Lagen übereinander. Der Übergangsbereich zwischen vier Lagen einerseits und zwei Lagen andererseits stellt eine konstruktionsbedingte Schwachstelle dar, an der die die beiden Kammern voneinander trennende Siegelnaht unter Einwirkung äußeren Drucks bevorzugt aufreißt, so dass eine Fluidverbindung zwischen den getrennten Kammern hergestellt wird. Es wird konstruktionsbedingt eine bevorzugte Schwachstelle an der die beiden Kammern voneinander trennenden Siegelnaht eingebaut, die bei Druckausübung von außen bevorzugt aufpeelt, da die Kräfte an der Siegelnaht hier vertikal ansetzen.The essential essence of the invention here is the bottom W fold. The The functional safety of the bag according to the invention is for the reasons mentioned below by sealing or welding the foils used for the production in the area the gusset of the W fold guaranteed. In this area there are four layers on top of each other, which are welded or sealed together. Otherwise, there are only two layers one above the other. The transition area between four layers on the one hand and two layers on the other hand, there is a design-related weak point at which the two Sealing seams separating chambers is preferred under the action of external pressure tears open so that a fluid connection between the separate chambers is established. Due to its design, it becomes a preferred weak point at the two chambers separating sealing seam built in, which is preferred when external pressure is applied peels up because the forces on the sealing seam apply vertically here.
Gemäß einer bevorzugten Ausführungsform des Siegelbeutels ist die die Kammern voneinander trennende Siegelnaht schmäler als die Siegelnaht der beiden äußeren Ränder. Vorteilhafterweise ist die die Kammern voneinander trennende Siegelnaht um 30% - 80% schmäler und besonders bevorzugt um 50% - 75% schmäler als die Siegelnaht der beiden Außenränder. Auf dieses Weise ist gewährleistet, daß die die Kammern voneinander trennende Siegelnaht schwächer ausgebildet ist als die beiden Außensiegelnähte, so daß die Gefahr eines ungewollten nach außen Leckens des Beutelinhalts - auch bei unsachgerechter Behandlung - deutlich reduziert ist. Durch die schmälere Ausgestaltung der die Kammern voneinander trennenden Siegelnaht ist nur ein geringer Druck auf die trennende Siegelnaht nötig, um eine Fluidkommunikation zwischen den zumindest zwei zunächst voneinander getrennten Kammern des Siegelbeutels zu gewährleisten.According to a preferred embodiment of the sealing bag, the chambers are apart from one another separating sealing seam narrower than the sealing seam of the two outer edges. advantageously, the sealing seam separating the chambers is 30% - 80% narrower and particularly preferably 50% - 75% narrower than the sealing seam of the two outer edges. This ensures that the sealing seam separating the chambers from one another is weaker than the two outer sealed seams, so that the risk of unwanted leakage of the contents of the pouch - even with improper handling - is significantly reduced. Due to the narrower design of the chambers from each other separating sealing seam, only a slight pressure on the separating sealing seam is necessary to fluid communication between the at least two initially separated ones Ensure chambers of the sealing bag.
Gemäß einer weiteren bevorzugten Ausführungsform weist die die Kammern voneinander trennende Siegelnaht zumindest eine Sollbruchstelle, insbesondere in Form einer Spitze auf. Bei dieser Ausgestaltung ist es möglich, durch Druck auf den Teil des Siegelbeutels, in dessen Kammer die Spitze ragt, eine Peeling-Wirkung auf die Spitze zu erzeugen, so daß die Siegelung an der Stelle der Spitze aufbricht und eine Fluidkommunikation mit der anderen, ursprünglich getrennten Kammer zuläßt. Die Ausgestaltung der Sollbruchstelle in Form einer Spitze ist deshalb besonders vorteilhaft, da die Druckkräfte, die bei einem Zusammendrücken des Siegelbeutelteils, in den die Spitze hineinragt, von allen Seiten auf die Spitze einwirken, so daß der Punkt der höchsten Peeling-Wirkung sich an der Spitze konzentriert.According to a further preferred embodiment, the chambers face one another separating sealing seam at least one predetermined breaking point, in particular in the form of a tip. With this configuration, it is possible to apply pressure to the part of the sealing bag The tip of the chamber protrudes to create a peeling effect on the tip, so that the Seal breaks at the point of the tip and fluid communication with the other, originally allows separate chamber. The design of the predetermined breaking point in the form of a Tip is particularly advantageous because the compressive forces that occur when compressed of the sealed bag part into which the tip protrudes, act on the tip from all sides, so that the point of the highest peeling effect is concentrated at the top.
Gemäß einer weiteren Ausführungsform der Erfindung weist die die Kammern voneinander trennende Siegelnaht eine geringere, vorzugsweise eine 20% - 80% geringere und besonders bevorzugt eine 50% - 75% geringere Festigkeit als die Randsiegelnähte auf. Somit werden die Seitennähte bevorzugt stärker versiegelt als die Mittelnähte. Dieses Merkmal trägt deutlich zur Funktionssicherheit des Siegelbeutels bei.According to a further embodiment of the invention, the chambers face away from each other separating sealing seam a smaller, preferably a 20% - 80% smaller and special preferably a 50% - 75% lower strength than the edge sealing seams. Consequently the side seams are preferably sealed more than the center seams. This characteristic contributes significantly to the functional safety of the sealed bag.
Ein weiterer Vorteil der Erfindung ergibt sich aus der in Form einer W-Falte geformten Bodenwand, die gleichzeitig als Standboden dienen kann. Dieser weist nach einer Befüllung des Mehrkammerbeutels eine im wesentlichen ovalförmige Standfläche auf.Another advantage of the invention results from the bottom wall shaped in the form of a W fold, which can also serve as a stand. After filling the Multi-chamber bag has an essentially oval base.
Gemäß einer weiteren Ausführungsform ist die Vorderwand, die Rückwand sowie die Bodenwand einstückig aus einem gemeinsamen Folienzuschnitt hergestellt. Diese vorteilhafte Ausgestaltung trägt weiter zur Funktionssicherheit des Siegelbeutels bei, da bei einer solchen einstückigen Ausführungsvariante ein Aufbrechen der Siegelung bzw. Verschweißung der einzelnen Wandteile nicht zu befürchten ist. Ebenso ist durch eine einstückige Beutel-Grundform die Anzahl der Arbeitsgänge zur Herstellung des Beutels deutlich reduziert, da die Bodenwand nunmehr nicht mehr zwischen die Vorder- und die Rückwand eingesiegelt werden muß. Somit kann die Anzahl der Siegelschritte bei einem Zweikammerbeutel nahezu halbiert werden.According to a further embodiment, the front wall, the rear wall and the bottom wall made in one piece from a common film blank. This advantageous embodiment further contributes to the functional safety of the sealed bag, since such a one-piece embodiment a breaking of the sealing or welding of the individual wall parts is not to be feared. Likewise, through a one-piece basic bag shape the number of operations for the production of the bag is significantly reduced since the Bottom wall can no longer be sealed between the front and rear walls got to. Thus, the number of sealing steps in a two-chamber bag can be almost be halved.
Vorzugsweise weisen die jeweils einander zugekehrten äußeren Ränder der bodenseitigen W-Falte eine Ausstanzung auf, so dass in diesem Bereich die jeweils einander abgekehrten Ränder der W-Falte bzw. die äußeren Ränder von Vorder- und Rückseite des Beutels unmittelbar miteinander verschweiß- bzw. versiegelbar sind. Damit wird der Mehrkammerbeutel im Bereich der beiden äußeren Ränder der W-Falte zusammengehalten. Wie oben erwähnt, entsteht damit nach Befüllung des Mehrkammerbeutels eine etwa ovalförmige Standfläche. Bei Bedarf kann die Randsiegelung getrennt werden, so dass der Beutel ohne Ausbildung eines statischen Standbodens bodenseitig V-förmig auseinander gespreizt werden kann. Auf jeden Fall ist durch die randseitige Ausstanzung im Bereich der Bodenfaltung sichergestellt, dass auch nur in diesem Bereich zwei Folienlagen aufeinanderliegen, die miteinander verschweißt bzw. versiegelt sind.The facing outer edges of the base preferably have W fold out a punched-out area so that the areas facing away from each other in this area The edges of the W fold or the outer edges of the front and back of the bag immediately are weldable or sealable to one another. So that the multi-chamber bag in Area of the two outer edges of the W fold held together. As mentioned above, arises thus an approximately oval-shaped base after filling the multi-chamber bag. at The edge seal can be separated as needed so that the pouch is formed without a static base can be spread apart on the bottom in a V-shape. In any Case is ensured by the punching out in the area of the bottom fold that only in this area are two layers of film lying on top of one another, which are welded together or are sealed.
Nach Befüllung der wenigstens zwei Kammern werden diese mittels einer gemeinsamen Kopfnaht vorzugsweise von im wesentlichen derselben Stärke wie die Randsiegelnähte fluiddicht verschlossen.After the at least two chambers have been filled, they are filled by means of a common one Head seam preferably of substantially the same thickness as the edge sealing seams in a fluid-tight manner locked.

In den Figuren 1 bis 3 ist ein Mehrrandsiegelbeutel 10 mit zwei durch eine hier vertikale Siegelnaht
bzw. sog. "Peelnaht" 11 fluiddicht voneinander getrennten Kammern 12, 13 dargestellt,
wobei die die Kammern voneinander trennende Siegelnaht 11 unter Einwirkung äußeren
Drucks an einer bevorzugten Schwachstelle, auf die weiter unten noch näher eingegangen
wird, aufreißt und eine Fluidverbindung zwischen den getrennten Kammern 12 und 13
herstellt. Der Beutel 10 ist bei der dargestellten Ausführungsform aus einem einzigen bzw.
gemeinsamen Verbundfolienzuschnitt hergestellt und umfasst eine Vorderwand 14, Rückwand
15 sowie Bodenwand 16, wobei die Bodenwand 16 in Form einer sog. W-Falte 17 ausgebildet
ist. Vorder- und Rückwand einschließlich W-Falte 17 sind sowohl längs Ihrer beiden
äußeren Ränder 18 und 19 als auch zwischen diesen durch die erwähnte Peelnaht 11 unter
Ausbildung von zwei Beutelkammern 12, 13 miteinander verschweißt oder versiegelt, und
zwar derart, dass im Bereich des Zwickels 20 der bodenseitigen W-Falte 17 vier Folienlagen
miteinander verschweißt bzw. versiegelt sind, während im übrigen Bereich jeweils nur zwei
Folienlagen aufeinander liegen. Dementsprechend zeichnet sich die die beiden Kammern 12,
14 voneinander trennende Siegelnaht bzw. Peelnaht 11 im Bereich des Zwickels durch einen
Übergang von vier Folienlagen in zwei Folienlagen aus. Dieser Übergang stellt eine definierte
Schwachstelle der die beiden Kammern voneinander trennenden Peelnaht 11 dar, die unter
Einwirkung von äußerem Druck als erstes aufreißt und eine Fluidverbindung zwischen den
beiden Kammern 12 und 13 herstellt.In Figures 1 to 3 is a multi-edge sealed
