Description
Die vorliegende Erfindung betrifft einen stabilisierten, flexiblen, kubischen Behälter, umfassend ein fortlaufendes und mit Ausstanzungen versehenes röhrenförmiges Basisteil, dessen nicht ausgefülltes Volumen in den Eckbereichen mit äußeren Materialadaptionen versehen ist, deren innere offene Kanten unmittelbar hinter den Ausstanzungen überdeckend mit dem Basisteil mittels Materialverbindungen dicht verbunden sind.The present invention relates to a stabilized, flexible, cubic container, comprising a continuous and punched tubular base part, its unfilled volume in the corner areas with external material adaptations is provided, the inner open edges immediately behind the punched covering tightly connected to the base part by means of material connections are.
Ein gattungsgemäßer, stabilisierter, flexibler, kubischer Behälter ist, beispielsweise, aus der WO 93/14007 bekannt. Dabei wird das röhrenförmige Basisteil aus einer Materiallage durch Verbinden zweier Kanten hergestellt. Das Verbinden ist nicht nur zeit- und somit kostenaufwändig, sondern kann auch zu einer Schwachstelle in dem Behälter führen. Darüber hinaus kann der Behälter nur aus einem Gewebe und nicht aus Kunststofffolien hergestellt werden, da die Verwendung von Nähten, wie sie in diesem Behälter vorgesehen sind, bei der Verwendung von Kunststofffolien zu Leckagen führen würden.A generic, stabilized, flexible, cubic container is, for example, known from WO 93/14007. The tubular base part becomes one Material layer produced by connecting two edges. Connecting is not only time and thus costly, but can also become a vulnerability in the Guide the container. In addition, the container can only be made of one fabric and not can be made from plastic films, since the use of seams as in this container are provided when using plastic films too Would cause leakage.
In der Packmittelbranche sind verschiedene Versuche unternommen worden, um großvolumige Kartonagen, biegwandige, d.h. halbsteife Klappcontainer oder flexible Bulkcontainer (FIBC) zu stabilisieren.Various attempts have been made in the packaging industry to: large-volume cardboard boxes, flexural, i.e. semi-rigid folding container or Stabilize flexible bulk containers (FIBC).
In erster Linie sollte das Ausbauchen der Seitenwandflächen über deren vorgegebene Maßfläche hinaus verhindert werden. Insbesondere bei nachgiebigen Wandflächen einer Außenverpackung war festzustellen, daß diese dem Druck von fließfähigen Trockenprodukten nicht widerstanden.First and foremost, the bulging of the side wall surfaces should go beyond their predefined Dimensional area can be prevented. Especially with flexible wall surfaces An outer packaging was found to be the print of flowable Dry products not withstood.
In Kartonagen konnten durch einen achteckigen Einsatz die genannten Nachteile ausreichend vermieden werden. In cardboard boxes, the disadvantages mentioned could be achieved through an octagonal insert be sufficiently avoided.
Bei flexiblen Behältem, meist hergestellt aus festen Gewebestoffen (FIBC), wirkten übereck eingenähte, zusätzliche Wandteile vorteilhaft druckentlastend. In vielen Fällen sollen aber wegen des Produktschutzes Folien-Liner eingesetzt werden, deren wandgerechte Auslegung bei einer inneren Kammerbildung des Behälters nicht möglich ist. In solchen Fällen wurde deshalb die Forderung erhoben, den Folien-Liner selbst zu stabilisieren. Wegen der geringen Wanddicke von Folien, kam für die Fertigung nur das Schweißverfahren in Betracht. Die Stabilisierung ist durch das gesonderte Einschweißen eines Rundgürtels (Innenring) mit besonderer Rückhaltekraft erreicht worden. Hierzu wird auf die EP-A1-0 276 878 verwiesen. Bei dieser Methode muß ein bereits vorgeformter flexibler Liner irgendwie geöffnet werden, um einen Innenring schweißtechnisch mit den Folien-Innenseiten zu verbinden. Diese umständliche und nicht immer sichere Adaptierung wird mit dem in der US-A-5 618 255 vorgesehenen Herstellweg zwar vermieden, weil die Verbindung von Gürtel und Außensack zunächst in offener Flachlage geschieht. Einen danach notwendige Seitenfalten-Schlauchbildung bei mehreren Meter Breite und Länge erweist sich als offenkundig schwierig. Die abschließende Formbildung des Ein- und Auslaufstutzens verlangt eine Einzelfertigung.It worked with flexible containers, mostly made of solid fabric (FIBC) additional wall parts sewn in at a corner, advantageously relieving pressure. In many However, cases should be used because of the product protection film liners, their Wall-appropriate design with an internal chamber formation of the container is not is possible. In such cases, the demand was made, the foil liner stabilize itself. Because of the small wall thickness of foils, came for the Manufacturing only considering the welding process. The stabilization is through that separate welding of a round belt (inner ring) with special Retention force has been achieved. For this, reference is made to EP-A1-0 276 878. With this method, a pre-formed flexible liner has to be opened somehow to weld an inner ring with the inside of the film connect. This cumbersome and not always safe adaptation is with the avoided in the manufacturing route provided in US-A-5 618 255 because of the connection belt and outer bag first happen in an open flat position. a then necessary gusseted hose formation with a width of several meters and Length turns out to be obviously difficult. The final formation of the Inlet and outlet sockets require one-off production.
Der Erfindung lag deshalb die Aufgabe zugrunde, den gattungsgemäßen, stabilisierten, flexiblen, kubischen Behälter derart weiterzuentwickeln, daß er die Nachteile der nach bekannten Verfahren hergestellten Behälter nicht aufweist. Diese Aufgabe wird durch die Lehre des Haupfanspruchs gelöst. Durch diese Art des Aufbaus wird im Gegensatz zum vorherigen oder späteren Einbringen eines stabilisierten Gürtels die Stabilisierung mittels einer durchlaufenden inneren Röhre als Ausgangspunkt der Fertigung erreicht. Dieses Grundkonzept hat den Vorteil, daß alle weiteren Fertigungsschritte außen an einem nahtlosen Basisschlauch ansetzen können. Ein weiterer Vorteil gegenüber anderen Herstellmethoden liegt in der Vermeidung von vielen Schwachpunkten, die beim nachträglichen inneren Einschweißen eines Gurtels auftreten können, beispielsweise Nahtrisse durch abschälende Zugspannung, Schweißfehler und Positionsungenauigkeiten, Verunreinigungen durch Öffnen eines Schlauches. Dagegen wird die stabilisierende Säule des durchlaufenden Basisschlauchs gemäß der Erfindung durch keinen inneren Nahtansatz geschwächt. Auch Positionsverschiebungen sind nicht möglich, da ja gar kein Gürtel eingebracht wird. Die Innenfläche des Basisschlauches bleibt von Verunreinigungen geschützt, da der Schlauch nicht geöffnet werden muß. Die äußeren Materialadaptionen in Form von Flachfolien oder Halbschläuchen gewährleisten außerdem eine partikelarme Fertigung. Alle nachträglich zugeführten Adaptionen werden von außen an diesen Basisschlauch angebracht.The invention was therefore based on the object, the generic, stabilized, to further develop flexible, cubic containers in such a way that the Disadvantages of the container produced by known methods does not have. This task is solved by teaching the main claim. This type of construction is opposed for the previous or later introduction of a stabilized belt stabilization using a continuous inner tube as a starting point of production achieved. This basic concept has the advantage that everyone Start further manufacturing steps on the outside of a seamless base hose can. Another advantage over other manufacturing methods is that Avoiding many weak points that can occur during the subsequent internal welding of a belt, for example Seam tears due to peeling tension, welding defects and Position inaccuracies, contamination by opening a hose. In contrast, the stabilizing column of the continuous base hose is in accordance with the invention weakened by no inner seam approach. Also Position shifts are not possible because no belt is inserted at all. The inner surface of the base hose remains protected from contamination because of the Hose does not have to be opened. The external material adaptations in the form of Flat films or half-tubes also guarantee a low particle content Production. All subsequent additions are made from the outside Base hose attached.
Der Basisschlauch, der als Seitenfaltenschlauch ein röhrenförmiges Element darstellt, muß geeignete und ausreichend viele Ausstanzungen erhalten, um bei späterer Befüllung einen reibungslosen Materialdurchfluß in die Taschen bildenden äußerem Materialadaptionen zu gewährleisten. Das gleiche gilt für die Entleerung.The base tube, which as a gusseted tube is a tubular element represents, must have suitable and sufficient number of punched holes in order to later filling a smooth flow of material into the pockets forming to ensure external material adaptations. The same applies to emptying.
Im nächsten Arbeitsschritt werden der Schlauchfolie über die einzelnen Seitenfalten von außen Materialbahnen zugeführt. Diese können entweder 8 Flachfolien oder 4 Halbschläuche sein. Halbschläuche entstehen durch eine seitlich geschlitzte Schlauchfolie oder durch deckungsgleich gefaltete Flachfolien. Durch eine geringe Öffnung der Halbschläuche gelangt jeweils eine Seite in Ober- und Unterlage an die Folie des Basisschlauchs. Dadurch entstehen durch die äußeren Materialadaptionen Außentaschen, die mittels einer über die gesamte Länge des späteren Behälters entsprechenden Längsschweißung oben und unten mit dem Basisschlauch oder der jeweiligen Schlauchseitenfalte unmittelbar hinter den Ausstanzungen überdeckend verbunden werden. Diese ergänzenden Außentaschen füllen dann den Eckraum eines späteren Behälters aus, soweit er von der inneren, raumreduzierten Schlauchfolie nicht erreicht werden kann. Dies soll ja gerade nicht geschehen, weil eine Schlauchfolie nur in dieser Form als Schlauchfolie im Inneren mit weitaus weniger Dimensionierung als der Mantelumfang des Behälters den starken Druck des fließfähigen Füllguts auffangen kann. Die restliche Füllfläche in den Ecken wird durch die gebildeten Außentaschen umgeben und ist dort erheblich geringerem Druck ausgesetzt. Wenn anstelle der Zuführung von 4 Halbschläuchen der Einsatz von 8 Flachfolien erfolgt, die später an den noch offenen Außenkanten schweißtechnisch geschlossen werden müssen, ist die Bahnführung und die Verarbeitung besonders einfach und sicher.In the next step, the tubular film is over the individual gussets Material webs fed from outside. These can either be 8 flat foils or 4 Be half hoses. Half tubes are created by a slit on the side Tubular film or congruently folded flat films. By a slight Opening of the half-tubes reaches one side in the top and bottom Foil of the base tube. This results from the external material adaptations Outer pockets, which correspond to the entire length of the later container by means of Longitudinal welding above and below with the base hose or the covering the respective hose side fold immediately behind the punched-out areas get connected. These additional outside pockets then fill the corner room a later container, as far as it from the inner, space-reduced tubular film cannot be reached. This is not supposed to happen because one Tubular film only in this form as inner tubular film with far less Dimensioning as the jacket circumference of the container the strong pressure of the flowable filling material can catch. The remaining fill area in the corners will surrounded by the formed outer pockets and is considerably less there Exposed to pressure. If instead of feeding 4 half hoses the insert of 8 flat foils, which are later on the still open outer edges must be closed in terms of welding technology is the web guide and the Processing particularly easy and safe.
Der mit äußeren Materialadaptionen ergänzte Basisschlauch in der Form eines Seitenfaltenschlauchs wird schließlich flachliegend an den Ecken einer bekannten Konturschweißung unterzogen, die einen sog. Flaschenhals ausbildet. Dieser dient sowohl als Einfiill- wie als Auslaufstutzen und entsteht in Einheit mit dem röhrenförmigen Element, also mit dem stabilisierenden Basisschlauch.The basic hose in the shape of a supplemented with external material adaptations Side gusseted tubing will eventually lie flat at the corners of a known one Contour welding, which forms a so-called bottle neck. This serves both as a filler neck and as a spout and is created in unity with the tubular element, i.e. with the stabilizing base hose.
Als Werkstoffe kommen in erster Linie Kunststoff-Folien in Betracht. Aber auch andere Werkstoffe (z.B. Papier) sind einsetzbar. Als Verbindungsmethode eignet sich bei Kunststoffen vorzugsweise die Schweißtechnik, aber auch andere naht- und klebetechnische Verbindungen kommen in Betracht.Plastic films are primarily considered as materials. But also other materials (e.g. paper) can be used. Suitable as a connection method welding technology is preferred for plastics, but also other seams and Adhesive connections can be considered.
Auf diese Art stabilisierte Behälter eignen sich nicht nur für Großbehälter, sondern auch für kleinere Gebinde, wenn das Füllgut dort eine Formveränderung durch Ausbauchen der Wandung hervorruft. Bisher war dieser Ausbaucheffekt in vielen Fällen nur über den Einsatz starkwandiger Außenverpackungen zu vermeiden. Nunmehr kann auch mit einer nur dünnen Schutzmantelverpackung die gewünschte kubische Paketform erhalten bleiben. Die Formgebung einer stabilisierten Innenhülle ist variabel. Unterschiedliche Seitenlängen sind ebenso möglich, wie beliebig geformte Einfüll- und Auslaufstutzen. Bei richtiger Dimensionierung der inneren Schlauchsäule ist eine sehr gute Standfestigkeit erzielbar, so daß dort gegebenenfalls ganz auf eine Außenverpackung verzichtet werden kann.Containers stabilized in this way are not only suitable for large containers, but also also for smaller containers, if the filling material changes shape there Bulging of the wall. So far, this expansion effect has been in many Avoid cases only by using thick-walled outer packaging. Now you can do the desired with a thin protective jacket cubic package shape is retained. The shape of a stabilized inner shell is variable. different Side lengths are also possible, as are filler and outlet spouts of any shape. With the correct dimensioning of the inner tube column is a very good stability can be achieved, so that there may be completely on an outer packaging can be dispensed with.
