Description
POB019de/19.08.1998 1POB019en/19.08.1998 1
Die Erfindung bezieht sich auf eine Beuteltube mit einem Folienmaterial, das eine Stirnwand und zwei Seitenwände der Tube bildet, wobei die Seitenwände längs zwei Seitenrandabschnitten miteinander verbunden sind, und mit einem Schulterstück, das einen verschliessbaren Auslassstutzen und einen an der Stirnwand befestigten Flansch aufweist, dessen Form der Form der Stirnwand entspricht.The invention relates to a bag tube with a film material that forms an end wall and two side walls of the tube, the side walls being connected to one another along two side edge sections, and with a shoulder piece that has a closable outlet nozzle and a flange attached to the end wall, the shape of which corresponds to the shape of the end wall.
Es ist oft wünschbar, eine solche Beuteltube mit einer die Oeffnung des Schulterstücks verschliessenden Verschlusskappe nach unten gerichtet aufzustellen. Dabei besteht die Gefahr, dass die Tube umkippt, weil sich das Folienmaterial unter dem Gewicht des Inhalts der Tube verformt. Die Gefahr besteht insbesondere dann, wenn das Folienmaterial - in ebenfalls wünschbarer Weise - dünn, leicht und flexibel ausgebildet ist.It is often desirable to place such a bag tube with a closure cap closing the opening of the shoulder piece facing downwards. In this case, there is a risk that the tube will tip over because the film material will deform under the weight of the tube's contents. This risk is particularly present if the film material is thin, light and flexible - which is also desirable.
Eine Aufgabe der Erfindung besteht darin, eine Beuteltube der eingangs angegebenen Art so auszubilden, dass die vorstehend geschilderte Gefahr eines Umkippens, wenn die Tube wie angegeben auf den Kopf gestellt wird, verringert ist.One object of the invention is to design a bag tube of the type specified at the outset in such a way that the risk of tipping over described above when the tube is turned upside down as specified is reduced.
Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Flansch sich vom Auslassstutzen ausgehend entlang der Stirnwand bis zu einem mittleren Bereich jeder Seitenwand nach aussen erstreckt und entlang der Stirnwand in Richtung zu den beiden Seitenrandabschnitten der Seitenwände hin erstreckt.The object is achieved according to the invention in that the flange extends outwards from the outlet nozzle along the front wall to a central region of each side wall and extends along the front wall in the direction of the two side edge sections of the side walls.
Vorzugsweise können zwei vom Flansch ausgehende, an den mittleren Bereichen der Seitenwände anliegende Laschen vorgesehen sein. Diese bieten zusätzlich auch einen Schutz des Folienmaterials gegen Verdrehung oder Verletzung, wenn die Tube zum Abschrauben oder Aufschrauben einer Verschlusskappe an den Seitenwänden im Bereich der Stirnwand gefasst wird. Um die Restentleerung der Tube sicherzustellen, sind diese Laschen vorteilhaft flexibel zu gestalten.Preferably, two tabs extending from the flange and resting on the middle areas of the side walls can be provided. These also offer additional protection of the film material against twisting or damage when the tube is held on the side walls in the area of the front wall to unscrew or screw on a cap. In order to ensure that the tube is completely emptied, these tabs should be designed to be flexible.

Der in den Figuren 1 und 2 dargestellte und als ganzes mit 1 bezeichnete, deformierbare Behälter weist einen Schlauchkörper 2 mit einer Stirnseite 3 auf, welche ihrerseits mit einer durch einen Verschlusskörper 4 verschliessbaren - nachfolgend noch näher beschriebenen Auslassöffnung versehen ist.The deformable container shown in Figures 1 and 2 and designated as a whole by 1 has a hose body 2 with an end face 3, which in turn is provided with an outlet opening that can be closed by a closure body 4 - described in more detail below.
Der Schlauchkörper 2 besitzt seinerseits zwei Wände 5 und 6, die einen im wesentlichen rechteckigen Umriss haben, sich auf verschiedenen Seiten einer durch die Längsachse 7 verlaufenden Ebene 8 befinden und bezüglich dieser Ebene 8 spiegelsymmetrisch zueinander sind. Die beiden Wände 5 und 6 weisen auf einander abgewandten Seiten je einen streifenförmigen Randabschnitt 5a bzw. 6a und an ihrem dem Auslass abgewandten Ende je einen ebenfalls streifenförmigen Querabschnitt auf (von welchen nur der Abschnitt 5b der Wand 5 sichtbar gezeichnet ist). Die Randabschnitte der beiden Wände 5 und 6 liegen paarweise aneinander an und sind miteinander verschweisst. Wie noch näher erläutert wird, bestehen die beiden Wände 5 und 6 zusammen mit einem sie verbindenden Mittelabschnitt 9 aus einem einstückigen, folienartigen Verbundmaterial bestehend aus drei miteinander verbundenen Schichten aus PoIyester, Aluminium und Polypropylen.The hose body 2 in turn has two walls 5 and 6, which have a substantially rectangular outline, are located on different sides of a plane 8 running through the longitudinal axis 7 and are mirror-symmetrical to one another with respect to this plane 8. The two walls 5 and 6 each have a strip-shaped edge section 5a or 6a on the sides facing away from one another and a strip-shaped transverse section on their end facing away from the outlet (of which only section 5b of the wall 5 is visibly drawn). The edge sections of the two walls 5 and 6 lie against one another in pairs and are welded together. As will be explained in more detail, the two walls 5 and 6 together with a central section 9 connecting them consist of a one-piece, film-like composite material consisting of three interconnected layers of polyester, aluminum and polypropylene.
Die die Auslassöffnung aufweisende Stirnseite 3 des Schlauchkörpers 2 wird im wesentlichen durch den erwähnten Mittelabschnitt 9 gebildet. Auf diesem ist einThe front side 3 of the hose body 2, which has the outlet opening, is essentially formed by the mentioned central section 9. On this is a
POB019de/19.08.1998 4POB019en/19.08.1998 4
nachfolgend noch näher bezeichneter Auslass-Stutzen aus Kunststoff angeordnet, der als Teil des Verschlusskörpers 4 unter anderem zum Schutz der Stirnkanten 9a mit die Wände 5 und 6 überdeckenden Schutzlaschen 10 und zur Verstärkung der Stirnseite 3 mit seitlichen Schulterstützen 11 versehen ist.An outlet nozzle made of plastic, described in more detail below, is arranged, which as part of the closure body 4 is provided, among other things, with protective tabs 10 covering the walls 5 and 6 to protect the front edges 9a and with lateral shoulder supports 11 to reinforce the front side 3.
Der Mittelabschnitt 9 hat in dem in der Figur 2 dargestellten parallel zur Achse 7 projizierten Riss im wesentlichen die Form einer konvexen Linse, wobei die spitzwinkligen Ecken der im Stirnbereich 3 auslaufenden Seitenränder 5a und 6a flügelartig über die in der Figur gezeichnete und im Mittelabschnitt 9 vorgesehene Auslassöffnung 12 des Behälters 1 vorstehen. In der in der Figur 1 dargestellten Ansicht ist also der Mittelabschnitt 9 eingebuchtet und hängt beidseits der Symmetrie-Ebene 8 über die Stirnkante 9a mit je einer der beiden Wände 5 bzw. 6 zusammen. In den Bereichen der Ränder 5a und 6a vereinigen sich die beiden Stirnkanten 9a zu einer einzigen in der Symmetrie-Ebene 8 liegenden Falt-Kante.In the crack projected parallel to the axis 7 shown in Figure 2, the middle section 9 essentially has the shape of a convex lens, with the acute-angled corners of the side edges 5a and 6a running out in the front area 3 protruding like wings over the outlet opening 12 of the container 1 shown in the figure and provided in the middle section 9. In the view shown in Figure 1, the middle section 9 is therefore indented and is connected to one of the two walls 5 and 6 on both sides of the plane of symmetry 8 via the front edge 9a. In the areas of the edges 5a and 6a, the two front edges 9a merge to form a single folding edge lying in the plane of symmetry 8.
Zur Herstellung des in den Figuren 1 und 2 dargestellten Behälters wird in einem ersten Verfahrensschritt ein Folien- oder Verbundstoffwerkstück, dessen Breite doppelt so lang ist wie die Länge des Schlauchkörpers 2, über einen Keil gezogen und entlang der Werkstücklängsachse in zwei gleiche Hälften gefaltet, aus welchen dann die beiden Wände 5 und 6 des Schlauchkörpers 2 gebildet werden. Das Folien- oder Verbundstoffwerkstück kann hierbei zum Beispiel von einer Band-Rolle abgewickelt werden, wobei dann - wie nachfolgend noch erläutert wird - erst in einer bereits fortgeschrittenen Verfahrensphase vorgefertigte Schlauchkörper vom Bandmaterial bzw. vom Folienoder Verbundstoffwerkstück abgetrennt werden.To produce the container shown in Figures 1 and 2, in a first process step, a film or composite workpiece, the width of which is twice as long as the length of the tube body 2, is pulled over a wedge and folded along the workpiece's longitudinal axis into two equal halves, from which the two walls 5 and 6 of the tube body 2 are then formed. The film or composite workpiece can, for example, be unwound from a tape roll, whereby - as will be explained below - prefabricated tube bodies are only separated from the tape material or the film or composite workpiece in an already advanced process phase.
In einem zweiten Verfahrensschritt wird das gefaltete und vorzugsweise von einer Band-Rolle abgewikkelte Folien- oder Verbundstoffwerkstück in zur Herstellung einzelner Behälter bestimmte Folienabschnitte aufgeteilt. Hierzu wird das Werkstückband mittels einer Transportvorrichtung schrittweise um jeweils eine Breite des zuIn a second process step, the folded and preferably unwound film or composite workpiece from a tape roll is divided into film sections intended for the production of individual containers. To do this, the workpiece tape is gradually folded by one width of the
POB019de/19.08.1998POB019de/19.08.1998
bildenden Schlauchkörpers 2 weitertransportiert, die durch den FaIt gebildete Längskante des doppellagigen Werkstücks in konstanten Abständen quer zur Transportrichtung angeschnitten und zwischen jeweils zwei solcher Einschnitte je eine Auslassöffnung 12 ausgestanzt. Anschliessend werden die durch die Einschnitte gebildeten stirnseitigen Ecken der herzustellenden Behälter nach innen umgefalzt, die beiden aneinander anliegenden Hälften des durch das Anschneiden vorbereiteten Folienabschnittes quer zur Längsrichtung verschweisst und der so gebildete Schlauchkörper 2 mittels eines Schneidwerkzeugs vom übrigen Teil des Bandes getrennt, so dass ein Folienzuschnitt der in der Figur 3 dargestellten Form entsteht.forming tube body 2 is transported further, the longitudinal edge of the double-layer workpiece formed by the fold is cut at constant intervals transversely to the transport direction and an outlet opening 12 is punched out between each two such cuts. The front corners of the containers to be produced formed by the cuts are then folded inwards, the two adjacent halves of the film section prepared by the cutting are welded transversely to the longitudinal direction and the tube body 2 thus formed is separated from the rest of the band by means of a cutting tool, so that a film cut of the shape shown in Figure 3 is created.
Das Falzen der beiden stirnseitigen Ecken um den 5° bis 90°, beispielsweise 45°, betragenden Winkel &agr; (Fig. 4), hat nicht nur eine Verstärkung der Behälterberandung in diesem Bereich zur Folge. Durch die Bildung der Falze werden darüber hinaus scharfkantige Ecken vermieden, welche einen Benutzer bei unachtsamer Handhabung verletzen oder die zur Aufnahme der Behälter 1 dienenden Tragtaschen beschädigen können.Folding the two front corners at an angle α of 5° to 90°, for example 45° (Fig. 4), not only results in a reinforcement of the container edge in this area. The formation of the folds also avoids sharp corners, which can injure a user if handled carelessly or damage the carrying bags used to hold the containers 1.
In einem weiteren Verfahrensschritt, der zum Beispiel parallel zum vorstehend beschriebenen zweiten Verfahrensschritt abläuft, wird der in der Figur 7 dargestellte Verschlusskörper 4 bereitgestellt. Dieser besteht im hier vorliegenden Fall aus dem bereits vorstehend genannten Auslass-Stutzen 14 (Fig. 6) und einem Verschlussdeckel 15 (Figur 5), wobei letzterer mit seinem Innengewinde 16 auf dem Gewindeteil 13 des Auslass-Stutzens 14 aufgeschraubt ist. Wie man insbesondere aus der Figur 6 ersehen kann, ist der Auslass-Stutzen 14 noch mit den bereits vorstehend genannten Schutzlaschen 10 und Schulterstützen 11 versehen und so dimensioniert und mit dem eine ebene Stirnfläche aufweisenden Verschlussdeckel 15 verschliessbar, dass der herzustellende Behälter eine genügend hohe Standfestigkeit besitzt und als Stehbehälter aufgestellt werden kann.In a further process step, which runs parallel to the second process step described above, for example, the closure body 4 shown in Figure 7 is provided. In the present case, this consists of the outlet nozzle 14 already mentioned above (Figure 6) and a closure cover 15 (Figure 5), the latter being screwed onto the threaded part 13 of the outlet nozzle 14 with its internal thread 16. As can be seen in particular from Figure 6, the outlet nozzle 14 is also provided with the protective tabs 10 and shoulder supports 11 already mentioned above and is dimensioned and can be closed with the closure cover 15 having a flat front surface so that the container to be produced has a sufficiently high level of stability and can be set up as a standing container.
POB019de/19.08.1998 6POB019en/19.08.1998 6
Im Anschluss an die vorstehenden Verfahrensschritte wird ein Befestigungs-Stutzen 17 in Pfeilrichtung durch den in der Figur 8 gezeichneten und bereits aufgefalteten Zuschnitt des Schlauchkörpers 2 geführt und am stirnseitigen Ende des Schlauchkörpers, also am Mittelabschnitt 9 angeschweisst, aufgeklebt und/oder aufgepresst, wozu der Befestigungs-Stutzen 17 insbesondere mit einem ringförmigen Kragen 18 versehen ist, der mit dem Mittelabschnitt 9 die gewünschte Verbindung eingeht. Wie man aus der Figur 9 ersehen kann, durchdringt der zur Aufnahme des Verschlusskörpers 4 bestimmte Hals 19 des Befestigungs-Stutzens 17 im befestigten Zustand die Auslassöffnung 12 des Schlauchkörper-Zuschnittes und ragt aus diesem heraus. Zur optimalen Verbindung von Befestigungs-Stutzen 17 und Mittelabschnitt 9 kann der Kragen 18 noch zusätzlich mit ringförmig angeordneten, spitzartig zulaufenden Rippen 20 versehen sein.Following the above process steps, a fastening nozzle 17 is guided in the direction of the arrow through the already unfolded cut of the hose body 2 shown in Figure 8 and is welded, glued and/or pressed onto the front end of the hose body, i.e. the middle section 9, for which purpose the fastening nozzle 17 is provided in particular with an annular collar 18 which forms the desired connection with the middle section 9. As can be seen from Figure 9, the neck 19 of the fastening nozzle 17 intended to receive the closure body 4 penetrates the outlet opening 12 of the hose body cut in the fastened state and protrudes from it. For the optimal connection of the fastening nozzle 17 and the middle section 9, the collar 18 can also be provided with annularly arranged, tapered ribs 20.
Nach dem Aufpressen des Verschlusskörpers 4 auf dem Befestigungs-Stutzen 17, durch welches insbesondere das den Mittelabschnitt 9 bildende Folienstück zwischen dem Befestigungs-Stutzen 17 und dem Auslass-Stutzen 14 eingespannt wird, wird das pastöse Produkt durch die der Stirnseite 3 gegenüberliegende, im Produktionsablauf vorzugsweise nach oben gekehrte Öffnung des genannten Zuschnittes in den Schlauchkörper 2 eingefüllt. Anschliessend wird die noch verbleibende Öffnung des Schlauchkörpers 2 verschlossen und verschweisst, und der so fertigerstellte und aufgefüllte Behälter direkt an ein zur Endverpackung bestimmtes Packband weitergeleitet.After pressing the closure body 4 onto the fastening nozzle 17, by means of which in particular the piece of film forming the central section 9 is clamped between the fastening nozzle 17 and the outlet nozzle 14, the pasty product is filled into the tube body 2 through the opening of the said blank, which is opposite the front side 3 and preferably faces upwards during the production process. Then the remaining opening of the tube body 2 is closed and welded, and the thus finished and filled container is passed directly to a packing tape intended for final packaging.
Zur Entnahme des Produktes aus dem erfindungsgemässen Behälter 1 wird der Verschlussdeckel 15 entfernt und dann der Schlauchkörper 2, vom breitseitigen Ende her beginnend, zusammengedrückt. Das den Schlauchkörper 2 bildende Material ist vorzugsweise derart elastisch und insbesondere plastisch deformierbar, dass dieser nach dem Herausdrücken eines Teiles des Produktes seine zusammengedrückte Form durch den sogenannten "Rückstell-Effekt" imTo remove the product from the container 1 according to the invention, the closure lid 15 is removed and then the tube body 2 is compressed, starting from the wide end. The material forming the tube body 2 is preferably elastic and in particular plastically deformable in such a way that after a part of the product has been pressed out, it retains its compressed shape through the so-called "return effect" in the
POB019de/19.08.1998 7POB019en/19.08.1998 7
wesentlichen beibehält und keine Luft durch den Auslass Stutzen 14 einsaugt.essentially and does not suck in air through the outlet nozzle 14.
Abschliessend sei noch darauf hingewiesen, dass die durch das vorstehend beschriebene Verfahren herstellbaren Behälter verschiedenartig ausgebildet sein und sich daher vom gezeichneten Ausführungsbeispiel unterscheiden können. So kann der Behälter anstelle einer rechteckigen auch eine andere Umrissform haben. Auch können die Abmessungen und Proportionen der Behälter in weiten Grenzen variieren. Schliesslich können auch noch die Verschlussdeckel verschiedenartig geformt und zum Beispiel die Form einer Kugel oder eines Polyeders haben.Finally, it should be noted that the containers that can be manufactured using the method described above can be designed in different ways and can therefore differ from the example shown. For example, the container can have a different outline shape instead of a rectangular one. The dimensions and proportions of the containers can also vary within wide limits. Finally, the closure lids can also have different shapes and, for example, be in the shape of a sphere or a polyhedron.
Die in den Fig. 11 bis 13 dargestellte Beuteltube besitzt zwei Seitenwände 111 und 112 und eine Stirnwand 113, die alle von einem Stück Folienmaterial gebildet sind. Das Folienmaterial ist vorzugsweise dünn, leicht und flexibel. Es kann eine einfache Kunststoffolie oder auch ein Laminat sein. Wenigstens die dem Inneren der Tube zugekehrte Seite des Folienmaterials kann aus schweissbarem Kunststoff bestehen. Die beiden Seitenwände 111 und 112 sind längs zwei Seitenrandabschnitten 114 und 115 und längs eines Endrandabschnittes 116 dicht miteinander verbunden, insbesondere verschweisst.The bag tube shown in Fig. 11 to 13 has two side walls 111 and 112 and an end wall 113, all of which are formed from a piece of film material. The film material is preferably thin, light and flexible. It can be a simple plastic film or a laminate. At least the side of the film material facing the inside of the tube can consist of weldable plastic. The two side walls 111 and 112 are tightly connected to one another, in particular welded, along two side edge sections 114 and 115 and along an end edge section 116.
An der Stirnwand 113 ist ein Schulterstück befestigt, das eine verschliessbare Oeffnung in der Form eines Auslassstutzens 117 besitzt. Das Schulterstück besteht vorzugsweise aus einem schweissbaren Kunststoff. Von dem Auslassstutzen 117 geht ein Flansch 118 aus, der gleich wie die Stirnwand 113 gekrümmt ist. Der Flansch 118 liegt innen an der Stirnwand 113 an und ist daran dicht abschliessend befestigt, vorzugsweise festgeschweisst.A shoulder piece is attached to the front wall 113, which has a closable opening in the form of an outlet nozzle 117. The shoulder piece is preferably made of a weldable plastic. A flange 118 extends from the outlet nozzle 117 and is curved in the same way as the front wall 113. The flange 118 rests on the inside of the front wall 113 and is tightly attached to it, preferably welded.
Der Flansch 118 erstreckt sich, vom Auslassstutzen 117 ausgehend, bis zu je einem mittleren Bereich jeder Seitenwand 111, 112 nach aussen.· Dieser mittlere Bereich jeder Seitenwand hat, wie in Fig. 13 dargestellt, eine Breite c, die wenigstens gleich 20%, vorzugsweise wenigstens 30%, der ganzen Breite d jeder Seitenwand 111, 112 zwischen den Seitenrandabschnitten 114 und 115 ist. DerThe flange 118 extends outward from the outlet nozzle 117 to a central region of each side wall 111, 112. This central region of each side wall has, as shown in Fig. 13, a width c that is at least equal to 20%, preferably at least 30%, of the entire width d of each side wall 111, 112 between the side edge sections 114 and 115. The
POB019de/19.08.1998 8POB019en/19.08.1998 8
sich längs der Stirnwand 113 bis zu den oberen Enden der Seitenwände 111 und 112 nach aussen erstreckende Flansch 118 dient dazu, die Stirnwand 113 zu versteifen und dadurch die Gefahr zu verringern, dass die Tube umkippen könnte, wenn sie mit einer auf den Auslassstutzen 117 aufgeschraubten Verschlusskappe (nicht dargestellt) nach unten gerichtet aufgestellt wird.The flange 118 extending outward along the end wall 113 to the upper ends of the side walls 111 and 112 serves to stiffen the end wall 113 and thereby reduce the risk that the tube could tip over if it is placed facing downwards with a closure cap (not shown) screwed onto the outlet nozzle 117.
Zu dem gleichen Zweck weist der Flansch 118 zwei an der Stirnwand 113 befestigte Stützen 119 und 120 auf, die sich in Richtung zu den beiden Seitenrandabschnitten 114 und 115 der Seitenwände 111, 112 hin erstrecken. Die beiden Stützen 119 und 120 erstrecken sich vorzugsweise bis auf einen Abstand a (Fig. 13) zu den Seitenrandabschnitten 114 bzw. 115 hin, der höchstens gleich 20%, vorzugsweise höchstens 10%, des bei der Stirnwand 113 gemessenen Abstandes b zwischen den Seitenrandabschnitten ist.For the same purpose, the flange 118 has two supports 119 and 120 attached to the end wall 113, which extend in the direction of the two side edge sections 114 and 115 of the side walls 111, 112. The two supports 119 and 120 preferably extend to a distance a (Fig. 13) to the side edge sections 114 and 115, respectively, which is at most equal to 20%, preferably at most 10%, of the distance b measured at the end wall 113 between the side edge sections.
Der Flansch 118 kann aber auch bei den Rändern der Stirnwand 113 zwei abgewinkelte, parallel zu den Seitenwänden 111 und 112 verlaufende Laschen 121 und 122 aufweisen. Die Laschen 121 und 122 versteifen die der Stirnwand 113 benachbarten mittleren Bereiche der Seitenwände 111 und 112. Gleichzeitig schützen sie das Folienmaterial gegen Verdrehung und/oder Verletzung, wenn die Tube für das Abschrauben einer Verschlusskappe (nicht dargestellt) vom Auslassstutzen 117 mit einer Hand in den genannten Bereichen der Seitenwände gehalten wird. Anderseits sind die Laschen 121 und 122, um das vollständige Ausdrucken der Tube nicht zu behindern, vorzugsweise flexibler als die übrigen Teile des Flansches 118. Beispielsweise haben die Laschen 121, 122 eine kleinere Wandstärke als die übrigen Teile des Flansches 118.The flange 118 can also have two angled tabs 121 and 122 at the edges of the front wall 113, running parallel to the side walls 111 and 112. The tabs 121 and 122 stiffen the middle areas of the side walls 111 and 112 adjacent to the front wall 113. At the same time, they protect the film material against twisting and/or damage when the tube is held with one hand in the areas of the side walls mentioned for unscrewing a closure cap (not shown) from the outlet nozzle 117. On the other hand, the tabs 121 and 122 are preferably more flexible than the other parts of the flange 118 so as not to hinder the complete printing of the tube. For example, the tabs 121, 122 have a smaller wall thickness than the other parts of the flange 118.
