The lid (2) is a separate, prefabricated part fitted by means of a flange (5) engaging round the top edge (6) of the tube (1) and welded to the edge (6). This lid (2) has a part (21) of its surface at a lower level than its outer surface, with part of the lower level surface (21) extending near to the edge (6) of the tube, in such a way that the lid (2) engages round the edge (6) of the tube substantially in a U shape in the region of said part (21 ) of the lower level surface.

Description

Die Erfindung betrifft eine Packung für fließfähige Füll­güter mit einem durch mindestens eine Längssiegelnaht ge­bildeten Tubus, an dessen Enden Boden und Deckel ange­bracht sind, von denen der Deckel aus thermoplastischem Kunststoff ohne Trägermaterial besteht, an dem Tubus an­geschweißt ist und eine Ausgießeinrichtung aufweist, wobei der Tubus aus mindestens einseitig mit thermoplastischem kunststoffbeschichtetem Trägermaterial, z. B. Karton, be­steht.The invention relates to a package for flowable fillings with a tube formed by at least one longitudinal sealing seam, at the ends of which bottom and lid are attached, of which the lid consists of thermoplastic material without a support material, is welded to the tube and has a pouring device, the tube from at least one side with thermoplastic plastic-coated carrier material, e.g. B. cardboard.

Packungen dieser Art sind vielfach bekannt. Bei einer be­sonderen derartigen Packung ist der Deckel in Draufsicht rund und auf die im Querschnitt runde Tubuswand ange­spritzt, um eine sichere und flüssigkeitsdichte Befesti­gung des Deckels am oberen Tubusrand zu gewährleisten. Hierdurch sind aufwendige Maschinen mit exakt justierten Werkzeugteilen erforderlich, so daß Packungen der bekann­ten Art in großen Stückzahlen pro Zeiteinheit nur mit er­heblichem Aufwand hergestellt werden können.Packs of this type are widely known. In a special pack of this type, the cover is round in plan view and molded onto the tube wall, which is round in cross section, in order to ensure secure and liquid-tight attachment of the cover to the upper edge of the tube. As a result, complex machines with precisely adjusted tool parts are required, so that packs of the known type can be produced in large quantities per unit of time only with considerable effort.

Es ist eine weitere Flüssigkeitspackung bekannt, bei wel­cher der Boden aus einem separaten, ebenen, mindestens auf einer Oberfläche thermoplastischen Kunststoff aufweisenden Wandstück gebildet und am Rand des im Querschnitt runden Tubus angeschweißt ist, wobei die Ebene des Bodens inner­halb des Tubus liegt und quer zu den durch den Tubus ge­bildeten Seitenwänden der Packung angeordnet ist, wobei die Ränder des Bodens den oberen Tubusrand U-förmig über­greifen. Man hat diese Ausgestaltung des Bodens gewählt, weil er preiswert und in Hochleistungsmaschinen vorgefer­tigt, auf Lager gehalten und von diesen in günstiger Weise abgezogen und auf den Tubusrand aufgesiegelt werden kann. Durch das U-förmige Umgreifen des Deckelrandes über den (wegen des Bodens) unteren Tubusrand können die Schweiß­backen beidseitig den Tubusrand umgreifen und Druckkräfte ausüben, durch welche aber gerade die günstigste Versie­gelung und damit Flüssigkeitsdichtung geschaffen werden kann.Another liquid pack is known in which the bottom is formed from a separate, flat wall piece having at least one surface of thermoplastic and is welded to the edge of the tube, which is round in cross-section, the level of the bottom lying inside the tube and transverse to the tube is arranged by the tube side walls of the pack, the edges of the bottom overlap the upper tube edge in a U-shape. This design of the base was chosen because it is inexpensive and prefabricated in high-performance machines, kept in stock and can be removed from it in a favorable manner and sealed onto the edge of the tube. Due to the U-shaped gripping of the lid edge over the lower tube edge (because of the bottom), the welding jaws can grip the tube edge on both sides and compressive forces exercise, but through which the cheapest seal and thus liquid seal can be created.

Wünscht man nun aber bei einer Packung, den Deckel ent­sprechend zu befestigen, dann gelingt dies nur, wenn die Ausgießeinrichtung in erheblichem Abstand von dem Deckel­rand angeordnet ist. Außerdem wäre es nachteilig, wenn eine derartige Packung geöffnet und ihr Füllgut entleert werden müßte, weil das Füllgut nach Verlassen des Deckels auf eine tieferliegende Deckelwand laufen und am Rand wie­der über diesen hochstehenden Rand überströmen müßte. Ein derartiges Ausgießen ist ungünstig und nicht erwünscht. Will man etwa die Ausgießeinrichtung am Rand des Deckels anordnen, dann versagt das beidseitige Umgreifen des Tubus­randes zur Befestigung des Deckels an diesem vollständig.However, if one wishes to fasten the lid appropriately in a package, this can only be achieved if the pouring device is arranged at a considerable distance from the edge of the lid. It would also be disadvantageous if such a package had to be opened and its contents had to be emptied, because the contents would have to run onto a lower cover wall after leaving the cover and would have to flow over the raised edge again at the edge. Pouring of this type is unfavorable and undesirable. If, for example, one wants to arrange the pouring device on the edge of the cover, then reaching around on both sides of the edge of the tube for fastening the cover fails completely.

Aufgabe der Erfindung ist die Schaffung einer Packung der eingangs genannten Art, bei welcher ein einfach herstell­barer Deckel mit guten Gießeigenschaften in flüssigkeits­dichter Weise gut angebracht werden kann, ohne daß etwa die Stapelbarkeit einer solchen Packung erheblich beein­trächtigt würde.The object of the invention is to provide a pack of the type mentioned, in which a simple to produce lid with good pouring properties can be attached in a liquid-tight manner without the stackability of such a pack being significantly impaired.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Deckel als vorgefertigtes, separates Teil mittels eines den oberen Rand des Tubus umgreifenden Flansches aufge­setzt und mit dem Rand verschweißt ist und eine gegenüber der Außenkontur tieferliegende Teilfläche aufweist, welche teilweise an den Tubusrand derart herangeführt ist, daß der Deckel den Tubusrand im Bereich der Teilfläche U-för­mig umgreift. Der Erfinder hat unter Überwindung der vor­stehend angedeuteten Bedenken für eine Flüssigkeitspackung der eingangs genannten Art einen vorgefertigten Deckel vorgeschlagen, der außen am Rand einen einseitig heraus­stehenden Flansch aufweist mit einem derartigen Durchmes­ser, daß dieser Flansch den oberen Rand des Tubus außen umgreifen kann. Dadurch, daß aus der ursprünglichen und äußeren Ebene des Deckels gemäß weiterer Lehre der Erfin­dung eine Teilfläche in Richtung auf das Packungsinnere versenkt oder tiefergezogen angeordnet wird, kann überall dort, wo diese Teilfläche den Tubusrand berührt, eine U-förmige Umgreifung des Tubusrandes durch das Deckelma­terial erreicht werden Die Teilfläche wird also bis dicht an den Tubusrand herangeführt, so daß sie wie bei dem be­kannten Boden am Rand den Tubusrand U-förmige übergreift. Nur den Bereich der Ausgießeinrichtung spart man erfin­dungsgemäß aus, so daß die oben erwähnten Nachteile beim Ausgießen nicht mehr auftreten. Im übrigen verwendet man die günstige Form des Deckelrandes zum Aufbringen von Druck und Gegendruck beim Anschweißen des Deckels am Tu­busrand.This object is achieved in that the lid is placed as a prefabricated, separate part by means of a flange encompassing the upper edge of the tube and welded to the edge and has a partial surface which is lower than the outer contour and which is partially brought up to the edge of the tube in such a way that the lid engages around the tube edge in the area of the partial surface in a U-shape. While overcoming the concerns outlined above, the inventor proposed a prefabricated lid for a liquid pack of the type mentioned at the outset, which has a flange on the outside at the edge with a diameter such that this flange can grip around the top of the tube on the outside. In that from the original and outer plane of the lid, according to further teaching of the invention, a partial surface is sunk towards the inside of the pack or is drawn lower, wherever this partial surface touches the tube edge, a U-shaped encirclement of the tube edge can be achieved by the lid material brought close to the edge of the tube, so that it overlaps the tube edge U-shaped at the edge as in the known bottom. Only the area of the pouring device is omitted according to the invention, so that the disadvantages mentioned above no longer occur during pouring. Otherwise, the favorable shape of the lid edge is used to apply pressure and counterpressure when welding the lid onto the tube edge.

Es ist deshalb erfindungsgemäß besonders zweckmäßig, wenn die tieferliegende Teilfläche des Deckels im Abstand vor der Ausgießeinrichtung endet. Wenn nun der Fachmann Beden­ken hätte, daß im Bereich der Ausgießeinrichtung, sofern diese insbesondere am Deckelrand angeordnet sein soll, die günstigen Formvoraussetzungen für Druck und Gegendruck beim Schweißen entfallen und daher im Ausgießbereich eine Abdichtung nicht möglich wäre, wird hier durch die erfin­dungsgemäße Lehre ein Weg vorgeschlagen, wie dennoch eine gute Verschweißung und Abdichtung zwischen Deckel und Tubus am Tubusrand möglich ist: man nutzt beim Verschweißen des Deckels mit dem Papiertubus die Zugspannung im Papier aus. Besonders günstig gelingt diese Ausnutzung für die Gegen­kräfte der Schweißbacke, wenn sich die Ausgießöffnung in einem Deckelrandbereich befindet, der eine hohe Krümmung hat. Vorzugsweise ist der Deckel in Draufsicht viereckig ausgestaltet, und die Ausgießeinrichtung liegt in einer Ecke dieses Vierecks. Der Winkel beträgt hier etwa 90° und erzeugt damit eine nicht unerhebliche Zugspannung im Pa­pier. Diese reicht aus, um eine starke Gegenkraft beim Aufdrücken von Schweißbacken auf den Deckel von außen in Richtung auf die Tubusaußenfläche abzustützen.It is therefore particularly expedient according to the invention if the lower partial surface of the lid ends at a distance in front of the pouring device. If the expert had concerns that in the area of the pouring device, if this is to be arranged in particular on the edge of the lid, the favorable shape requirements for pressure and counterpressure during welding no longer apply and therefore sealing in the pouring area would not be possible, the teaching according to the invention provides a way here proposed how a good welding and sealing between the lid and tube at the tube edge is still possible: one uses the tensile stress in the paper when welding the lid to the paper tube. This exploitation is particularly favorable for the counter forces of the welding jaw if the pouring opening is in a lid edge area which has a high curvature. The top view is preferably of quadrangular design, and the pouring device lies in a corner of this quadrangle. The angle here is about 90 ° and thus creates a not inconsiderable tensile stress in the paper. This is sufficient to support a strong counterforce when welding jaws are pressed onto the lid from the outside in the direction of the outer tube surface.

Zweckmäßig ist es gemäß der Erfindung auch, wenn die die Ausgießöffnung der Ausgießeinrichtung umgebende Ebene etwa in der Höhe der Tubusoberkante liegt. Man kann auf diese Weise die vorstehend schon angesprochenen Gießeigenschaf­ten der erfindungsgemäßen Ausgießeinrichtung optimal ge­stalten. Nachdem die Flüssigkeit beim Ausgießen die Aus­gießöffnung verlassen hat, braucht sie nur über die diese Öffnung ümgebende Ebene weiterzufließen, um bis zu einer am äußersten Rand liegenden Gießkante zu gelangen, von welcher der Strom abreißen und einen Flüssigkeitsstrahl in gewünschter, idealer Weise bilden kann.It is also expedient according to the invention if the plane surrounding the pouring opening of the pouring device lies approximately at the height of the upper edge of the tube. In this way, the above-mentioned pouring properties of the pouring device according to the invention can be optimally designed. After the liquid has left the pouring opening during pouring, it only needs to continue flowing over the plane surrounding this opening in order to reach a pouring edge located at the outermost edge, from which the stream can break off and form a liquid jet in the desired, ideal manner.

  • FIG. 1 shows a perspective and broken view of the top view of a specially designed package with the lid according to the invention,
  • FIG. 2 shows a broken and schematic sectional illustration along the line II-II of FIG. 1,
  • Figure 3 is also a broken and schematic sectional view taken along the line III-III of Figure 1 and
  • Figure 4 is a plan view of a lid of a liquid pack in a different embodiment with a trapezoidal lower part.

Der allgemein mit 1 bezeichnete Tubus der Packung bildet die Seitenflächen und besteht aus beidseitig mit thermo­plastischem Kunststoff beschichtetem Papier. Am unteren Ende dieses Tubus ist ein nicht dargestellter Boden ange­bracht, der beispielsweise viereckig sein kann und aus dem umgefalteten Tubus der Packung als Faltverschluß ausgebil­det ist sowie eine Quersiegelnaht mit auf eine benachbarte Wandung umgefalteten Dreiecklappen aufweist.The tube of the pack, generally designated 1, forms the side faces and consists of paper coated on both sides with thermoplastic. At the lower end of this tube, a bottom (not shown) is attached, which can be, for example, square and is formed from the folded tube of the pack as a folding closure and has a transverse sealing seam with triangular flaps folded over onto an adjacent wall.

Der Deckel 2 ist in Draufsicht dreieckig ausgeführt, wo­bei zwei Ränder längs der oberen Kanten der zwei ebenen Seitenflächen verlaufen und die dritte, diese beiden Sei­ten verbindende Linie des Dreieckes über die Diagonale verläuft, wenn man die im Querschnitt unten und oben vier­eckige Packung von oben betrachtet. Sozusagen in der ande­ren Hälfte des Viereckes in Blickrichtung von oben befin­det sich im Bereich 3 der Packung (Figuren 1 und 4) eine Ausnehmung derart, daß das Volumen der Packung nach oben verjüngt ausgebildet ist. In dem abgeschnittenen Volumen­bereich ist ein Deckel 4 angebracht.The cover 2 is triangular in plan view, with two edges running along the upper edges of the two flat side surfaces and the third line of the triangle connecting these two sides running across the diagonal, if one looks at the package, which is square in cross-section below and above, from above . In the other half of the square, as seen from above, there is a recess in area 3 of the pack (FIGS. 1 and 4) such that the volume of the pack is tapered towards the top. A lid 4 is attached in the cut-off volume area.

Für die Erfindung ist der Deckel 2 von besonderer Wichtig­keit. Er ist ein vorgefertigtes, separates Teil aus ther­moplastischem Kunststoff ohne Trägermaterial. Am Außenum­fang weist der Deckel 2 einen Flansch 5 auf, der einseitig heraussteht und die Oberkante bzw. den oberen Rand 6 des Tubus 1 umgreift.The cover 2 is of particular importance for the invention. It is a prefabricated, separate part made of thermoplastic material without carrier material. On the outer circumference, the cover 2 has a flange 5 which projects on one side and engages around the upper edge or the upper edge 6 of the tube 1.

Der Deckel 2 weist aber außerdem eine tieferliegende Teil­fläche 21 auf, welche gegenüber derjenigen Ebene 22 in Richtung auf das Innere der Packung hin tiefergezogen oder versenkt ist, welche die Ausgießöffnung 7 der allgemein mit 8 bezeichneten Ausgießeinrichtung umgibt.However, the lid 2 also has a lower-lying partial surface 21, which is drawn or countersunk in relation to that plane 22 in the direction of the interior of the package, which surrounds the pouring opening 7 of the pouring device, generally designated 8.

Aus Figur 2 gemäß der Schnittlinie II-II der Figur 1 er­kennt man, daß überall dort, wo die tieferliegende Teil­fläche 21 bis an den Tubusrand 6 herangeführt ist, der Deckelrand den Tubusrand 6 U-förmig umgreift. Dies ist bei der Schnittdarstellung der Figur 2 auf beiden Seiten, d. h. rechts und links am Tubusrand 6 oben der Fall; während dies bei der Darstellung der Figur 3 gemäß Schnittlinie III-III der Figur 1 nur rechts der Fall ist. Weil der Schnitt III-III in Figur 1 von vorn nach hinten geknickt ist, d. h. zwar in der Mitte durch die Ausgießeinrichtung 8 vorn verläuft, hinten aber nicht durch den Griff 4 ver­läuft, sieht man in Figur 3 nicht den Griff sondern ledig­lich die schräge Tubuswandung.From Figure 2 according to the section line II-II of Figure 1 it can be seen that wherever the lower part 21 is brought up to the tube edge 6, the lid edge engages around the tube edge 6 in a U-shape. This is the case in the sectional view of FIG. 2 on both sides, ie on the right and left on the tube edge 6 above; while this is only the case on the right in the representation of FIG. 3 according to section line III-III of FIG. Because the section III-III in Figure 1 is bent from the front to the rear, that is to say runs in the middle through the pouring device 8 at the front, but does not extend through the handle 4 at the rear, one does not see the handle in Figure 3 but only the oblique tube wall .

Bei der Ausführungsform der Figur 1 ist die tieferliegende Teilfläche 21 so groß wie möglich ausgelegt und umgibt die Ausgießeinrichtung 8 möglichst allseitig bis auf die vor­dere Ausgießspitze 9, so daß das U-förmige Umgreifen des Deckelmaterials aus Thermoplast um den Tubusrand 6 weit­gehend sogar um die Ausgießeinrichtung 8 herumgezogen ist.In the embodiment of Figure 1, the lower-lying partial surface 21 is designed to be as large as possible and surrounds the pouring device 8 on all sides as far as possible except for the front pouring tip 9, so that the U-shaped encompassing of the thermoplastic lid material around the tube edge 6 largely even around the pouring device 8 has moved around.

Denkbar ist aber auch die andere Ausführungsform nach Fi­gur 4, bei welcher die tieferliegende Teilfläche 21 etwa Trapezform hat, ohne dichter an die Ausgießöffnung 7 her­anzureichen oder diese gar auf drei Seiten zu umfassen. Es hat sich bei Versuchen gezeigt, daß die Zugspannung im Papiermaterial des Tubus 1 ausreicht, um den Druck des Schweißbacken von außen nach innen im Bereich der Aus­gießeinrichtung gut abzustützen.However, the other embodiment according to FIG. 4 is also conceivable, in which the lower-lying partial surface 21 has an approximately trapezoidal shape without reaching closer to the pouring opening 7 or even encompassing it on three sides. It has been shown in tests that the tensile stress in the paper material of the tube 1 is sufficient to support the pressure of the welding jaw from outside to inside in the region of the pouring device.
