Description

Die Erfindung betrifft einen Ventilsack aus Papier oder ähnlichem Stoff mit in die Ventilöffnung hineinragendem Streifen oder ähnlichem Glied, und das Neue besteht darin, daß das Ende des Streifens zurückgefaltet ist und zullgenartig sich an die Gegenlippe des Ventils anlegend durch den Ventilkanal wieder hinausgeht. Hierdurch wird in sehr einfacher Weise ein Verkapseln der Ventilöffnung von innen her nach erfolgter Füllung des Sackes ermöglicht. The invention relates to a valve bag made of paper or the like Fabric with a strip or similar element protruding into the valve opening, and the new thing is that the end of the strip is folded back and zullgen-like rests against the mating lip of the valve and goes out through the valve channel. This enables the valve opening to be encapsulated from the inside in a very simple manner after the sack has been filled.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar und zeigt einen Schnitt durch die Ventilecke eines Kreuzbodenventilsackes in verschiedenen Arbeitszuständen. The drawing shows an embodiment of the invention and shows a section through the valve corner of a cross-bottom valve bag in various ways Working conditions.

Auf den Eckeinschlag 10 (Abb. 1) des zum Kreuzboden aufgezogenen Sackrohlings wird der Steifen 13 mit seinem Endteil 14 aufgelegt, der am Ende zur Zunge 15 umgefaltet ist. Dann wird gemäß Abb. 2 der Kreuzboden durch Zusammenschlagen der beiden Bodenklappen 11, 12 gebildet und hierauf nach. Abb. 3 das freie Streifenende 13 umgeschlagen und auf der oberen Bodenklappe 12 außen befestigt. On the corner entry 10 (Fig. 1) of the cross bottom drawn Sack blank of the stiffener 13 is placed with its end part 14, which at the end to Tongue 15 is folded over. Then, as shown in Fig. 2, the bottom of the cross is knocked together of the two bottom flaps 11, 12 formed and then after. Fig. 3 the free end of the strip 13 turned over and attached to the outside of the upper bottom flap 12.

Wird jetzt die zum Füllen des Sackes dienende Düse 16 in die in Abb. 3 durch den schwarzen Pfeil gekennzeichnete Ventilöffnung eingeschoben, so schiebt sie das Streifenende 15 nach innen in den Sack hinein so daß es frei in ihn hineinragt und das Füllgut 17 ungehindert durch die Düse 16 hindurch einströmen kann. Wird nach Füllung des Sackes die Düse 16 zurückgezogen, so nimmt der durch das Einführen der Düse 16 aus seiner flachgedrückten Lage rund aufgewölbte Ventilkanal infolge der Elastizität der Papierwände wieder anniihernd seine ursprüngliche flache Lage ein, und el)enso faltet sich die Zunge 15 wieder zuriick, wobei sie sich jedoch, wie Abb. 5 zeigt, von unten an den Eckanschlag 10 anlegt. Wird nun durch Umkippen des vollen Sackes Füllgut zoll innen gegen die Zunge 15 geschüttet, so driickt es diese gegen den Eckanschlag und verkapselt damit das Ventil, so daß jedes Austreten von Füllgut durch das Ventil hindurch verhindert wird, auch wenn der Sack bei der Beförderung geknautscht oder geknetet wird und sich hierdurch das Ventil etwas öffnen sollte. If the nozzle 16 used to fill the sack is now inserted into the position shown in Fig. 3 valve opening marked by the black arrow is inserted, so pushes they the end of the strip 15 inwards into the sack so that it protrudes freely into him and the filling material 17 can flow in unhindered through the nozzle 16. Will After the bag has been filled, the nozzle 16 is withdrawn, and the insertion takes place of the nozzle 16 from its flattened position as a result of the valve channel bulging around the elasticity of the paper walls almost returned to its original flat position a, and el) enso the tongue 15 folds back again, whereby it, however, as Fig. 5 shows, applies to the corner stop 10 from below. Is now by tipping over of the full sack of filling material is poured inward against the tongue 15, so it presses this against the corner stop and thus encapsulates the valve, so that any leakage of filling material through the valve is prevented, even if the sack is at the Transport is crumpled or kneaded and this opens the valve a little should.
