Description
Die Erfindung betrifft ein zylindrisches Innenventil oder "Schlauchventil" für Säcke zur Aufnahme von Schüttgut, wie pulver-, granulat- bzw. staubförmigen Gütern, mit verbesserter Schließwirkung.The invention relates to a cylindrical inner valve or "hose valve" for sacks for holding bulk goods, such as powdered, granular or dusty goods, with improved closing action.
Pulver-, granulat- bzw. staubförmige Güter, wie z. B. Ruß, hochdisperse Kieselsäure oder Lebensmittel, wie z. B. Mehl, werden in mit Innenventil versehenen Schüttgutsäcken, sogenannten Ventilsäcken versandt. Diese Ventilsäcke bestehen meist aus starkem, mehrschichtigem Papier. Sie werden über das Innenventil gefüllt und durch es verschlossen.Powder, granulate or dust-like goods, such as. As soot, finely divided silica or food such. B. flour, are shipped in bulk bags provided with an internal valve, so-called valve bags. These valve bags usually consist of strong, multilayer paper. They are filled via the internal valve and closed by it.
Es ist bekannt, die Innenventile von Papiersäcken ebenfalls aus mehrschichtigem, relativ steifem Papier zu fer- tigen. Solche Innenventile weisen jedoch den Nachteil auf, daß sie beim Herausziehen eines Füllstutzens nicht vollständig schließen und, insbesondere beim Transport, zu einem unerwünschten Austritt des Verpackungsgutes führen.It is known to fer the internal valves of paper bags also made of several layer, relatively stiff paper - term. However, such internal valves have the disadvantage that they do not close completely when a filler neck is pulled out and, particularly during transport, lead to an undesired escape of the packaging material.
Es ist ferner bekannt, die Gesamtlänge von Innenventilen für Ventilsäcke so zu bemessen, daß der Füllstutzen länger als das Innenventil ist (DE-OS 23 63 753).It is also known to dimension the total length of inner valves for valve bags so that the filler neck is longer than the inner valve (DE-OS 23 63 753).
Im übrigen ist bekannt, ein Innenventil für Ventilsäcke zum Transport von Pulvern oder staubförmigen Gütern mit einem flexiblen Einsatz zu versehen, welcher das innere Ende des Innenventiles bildet (DGBM 1 870 373). Die in manchen Fällen nicht befriedigende Verschlußwirkung kann nun erfindungsgemäß auf einfache und kostensparende Weise erheblich verbessert werden.For the rest, it is known to provide an inner valve for valve bags for the transport of powders or dusty goods with a flexible insert which forms the inner end of the inner valve (DGBM 1 870 373). The closure effect, which in some cases is unsatisfactory, can now be considerably improved in a simple and cost-saving manner according to the invention.
Die Erfindung erstreckt sich auf zwei nebengeordnete verbesserte zylindrische.Innenventile. Ein Gegenstand der Erfindung ist ein zylindrisches Innenventil für Säcke zur Aufnahme-von Schüttgut, dessen. Länge diejenige des in das Ventil einzuschiebenden.Abschnitts des Füllstutzens einer Absackmaschine unterschreitet, mit einem relativ steifen Einschubkanal und einem diesen fortsetzenden, die Ventillippen bildenden Endstück aus flexibler Folie, welches dadurch gekennzeichnet ist, daß die Ventillippen als Adhäsionsfolie ausgebildet sind.The invention extends to two subordinate improved cylindrical internal valves. An object of the invention is a cylindrical inner valve for bags for receiving bulk goods, the. Length falls below that of the section of the filler neck of a bagging machine to be inserted into the valve, with a relatively rigid insertion channel and an end piece made of flexible film which forms the valve lips and is characterized in that the valve lips are designed as an adhesive film.
Der zweite Gegenstand der Erfindung ist ein zylindrisches Innenventil für Säcke zur Aufnahme von Schüttgut, dessen Länge diejenige des in das Ventil einzuschiebenden Abschnitts des Füllstutzens einer Absackmaschine unterschreitet, mit einem.relativ steifen Einschubkanal und einem diesen fortsetzenden, die Ventillippen bildenden Endstück aus flexibler Folie, welches dadurch.gekennzeichnet ist, daß die obere Ventillippe die untere um mindestens den Durchmesser des.Ventilkanals überragt. Dabei können die Ventillippen zu einer noch weiteren Steigerung des Verschlußeffekts ebenso wie bei dem zuerst vorgestellten erfindungsgemäßen Innenventil ebenfalls als Adhäsionsfolie ausgebildet sein.The second object of the invention is a cylindrical inner valve for sacks for holding bulk material, the length of which is less than that of the section of the filler neck of a bagging machine to be inserted into the valve, with a relatively stiff insertion channel and an end piece made of flexible film, which forms the valve lips, which is characterized in that the upper valve lip projects beyond the lower by at least the diameter of the valve channel. In this case, the valve lips can also be designed as an adhesive film to further increase the sealing effect, as in the case of the inner valve according to the invention presented first.
Die Verlängerung der oberen Ventillippe gegenüber der unteren erbringt schon bei Benutzung normaler flexibler Folien den Vorteil, daß die obere Lippe bei geeigneter Sackstellung bzw. -neigung die untere Lippe überlappt und damit eine Verschlußwirkung herbeiführt, die im-Normalfall schon ohne Ausbildung des Endstücks als Adhäsionsfolie genügend transportsicher schließt.The extension of the upper valve lip compared to the lower one already provides more flexibility when using normal ones Films the advantage that the upper lip, with a suitable bag or tilt position overlaps the lower lip and thus brings about a sealing effect, in - closes normally sufficient transport certainly without the formation of the end piece as adhesion film.
Das die Ventillippen bildende Endstück aus flexibler Folie kann aus Kunststoffe wie Polyäthylen, PVC u. a. bestehen. Aber auch dünnes Papier, wie Seidenpapier, ist brauchbar, sofern die.Innenvent.ilkonstruktion das Merkmal der überlappbaren Ventillippen vorsieht.The end piece of flexible film forming the valve lips can be made of plastics such as polyethylene, PVC and the like. a. consist. However, thin paper, such as tissue paper, can also be used, provided that the interior valve construction provides the feature of the overlapping valve lips.
Das flexible Endstück kann eine beliebige Länge im Vergleich zu dem Gesamtventil aufweisen. Wesentlich ist, daß ein Teil desselben über die mehrschichtige, relativ starre Papierwand des Innenventils herausragt und so in.seiner Flexibilität nicht gehindert wird.The flexible end piece can have any length in comparison to the overall valve. It is essential that a part of the same protrudes over the multilayer, relatively rigid paper wall of the inner valve and thus its flexibility is not hindered.
Das flexible Endstück kann auf der Innenwand oder auf der Außenwand des Innenventils angeordnet sein.The flexible end piece can be arranged on the inner wall or on the outer wall of the inner valve.
Es kann auch zwischen den einzelnen Papierschichten des Innenventils befestigt sein, wobei als bevorzugte Befestigungsmethode das Verkleben angewandt wird. Die einzelnen Papierschichten des Innenventils können dabei an verschiedenen Stellen enden, d. h. die Wand des Innenventils kann stufenförmig zur Mündung des Innenventils im Sackinneren verlaufen.It can also be fastened between the individual paper layers of the inner valve, adhesive bonding being used as the preferred fastening method. The individual paper layers of the inner valve can end at different points, i. H. the wall of the inner valve can be stepped to the mouth of the inner valve in the interior of the bag.
Das flexible Endstück kann schlauchförmig sein, wobei sein Durchmesser dem Durchmesser des Innenventils angepaßt ist. Letzteres hat zylindrische Form, um mit dem zylindrischen Füllstutzen der Absackmaschine zu korrespondieren. In einer Ausführungsform der Erfindung kann der schlauchförmige Einsatz im freien Bereich, d. h. dort, wo er nicht mit der Papierwand des Innenventils verbunden ist, geschlitzt sein.The flexible end piece can be tubular, its diameter being adapted to the diameter of the inner valve. The latter has a cylindrical shape to correspond to the cylindrical filler neck of the bagging machine. In one embodiment of the invention, the tubular Use in open areas, ie where it is not connected to the paper wall of the inner valve, be slotted.
Das flexible Endstück kann aus einer, zwei oder mehreren rechteckigen Folien bestehen. Wenn mehrere Folien verwendet werden, sind sie der Wand des Innenventils so angepaßt; daß sich ihre Enden überlappen. Dabei können die überlappenden Teile im Bereich der Papierwand des Innenventils verklebt und im Bereich des flexiblen Endstücks frei gegeneinander verschieblich sein.The flexible end piece can consist of one, two or more rectangular foils. If several foils are used, they are adapted to the wall of the inner valve; that their ends overlap. The overlapping parts can be glued in the area of the paper wall of the inner valve and freely displaceable in the area of the flexible end piece.
Das erfindungsgemäße Innenventil ist dem Füllstutzen der Abpackmaschine längenmäßig angepaßt und wird daher von innen durch Reste des Transportgutes nicht verschmutzt, wenn dieser aus dem Innenventil zurückgezogen wird. Die erfindungsgemäße Ausbildung der Ventillippen als Adhäsionsfolie bzw. die Verlängerung der oberen Ventillippe gegenüber der unteren, gegebenenfalls in Verbindung mit der Verwendung einer Adhäsionsfolie für diese Lippen schafft einm gegenüber bekannten Schlauchventilen bezüglich der Transportsicherheit erheblich verbesserten Verschluß.The inner valve according to the invention is matched in length to the filler neck of the packaging machine and is therefore not contaminated from the inside by remnants of the goods to be transported when it is withdrawn from the inner valve. The inventive design of the valve lips as an adhesive film or the extension of the upper valve lip relative to the lower one, possibly in conjunction with the use of an adhesive film for these lips, creates a closure which is considerably improved compared to known hose valves with regard to transport safety.
Ein mit allen Merkmalen der Erfindung ausgestattetes Innenventil wird anhand der anliegenden Zeichnung näher erläutert:
- In dem
Papiersack 1 ist derFüllstutzen 2 einer Absackmaschine (nicht gezeigt) in das Innenventil desPapiersackes 1 eingeführt.
- In the
paper bag 1, thefiller neck 2 of a bagging machine (not shown) is inserted into the inner valve of thepaper bag 1.
Das Ende des Füllstutzens 2 ragt dabei über das Ende 5 des Innenventils hinaus in den Papiersack hinein. Das Innenventil besteht aus den relativ steifen, den Einschubkanal für den Füllstutzen bildenden Papierwänden 3 und 4, zwischen denen die flexible Adhäsionsfolie 6 verklebt ist. Von der gesamten Länge 7 der Adhäsionsfolie 6 befindet sich ein Teil außerhalb des Endes 8 der Papierwände 3 und 4 und bildet das flexible Endstück mit den Ventillippen. Diese können in einer Ebene liegen, wenn das Endstück als Adhäsionsfolie ausgebildet ist. Im vorliegend gezei.gten Fall überragt die obere Ventillippe 9 den unten vorstehenden Teil der Adhäsionsfolie 6 um mehr als den Durchmesser des Ventilkanals. Dadurch legt sich erstere beim Zurückziehen des Füllstutzens um letztere herum und bewirkt dadurch den Verschluß. In der gezeigten Ausführungsform besteht das Endstück jedoch aus Adhäsionsfolie, wodurch die schon bei nichtadhäsiv ausgerüsteten Folien gute Verschlußsicherheit noch weiter gesteigert wird.The end of the
