Definitions
- the invention relates to a stand-up pouch made of a heat-sealable film, with a front and a back, which are connected to one another at their edges, wherein a resealable screw closure is provided in the front or the back, which has a connection piece on which a thread is applied, which is in engagement with a thread of a releasable screw cap.
- So-called disposable bags are known several times in practice. They are used, for example, to fill beverages, which are often sachets, ie with an amount of content that is consumed by the consumer on one occasion. Such bags generally have a weakening point on their front side which can be pierced with a drinking straw, the contents of the bag also being removed via the drinking straw. It is also common, depending on the volume of the bags, to cut these bags open so that the contents can be emptied. Bags of this type can be disposed of easily since they take up only a small volume. However, the consumer is forced to always empty the entire bag or to empty the bag in the case of filling non-drinkable liquid, since bags of this type are not resealable.
- a stand-up pouch of the type mentioned is known from DE-OS 17 86 019.
- This bag has a screw cap attached to the flat side, which is attached with its flange to the outside of the bag. With such stand-up pouches, leaks can occur at the closure; the sometimes high moments that occur when the screw cap is closed again can lead to damage.
- the socket of the screw cap passes through the bag and is attached at its inner end with a sealing flange on the inside of the bag, that the sealing flange has a bevelled outer edge, which together with the associated side of the bag a radially after forms an externally opening, V-shaped circumferential groove which is at least partially closed by the sealing layer melted during sealing.
- the diameter of the sealing flange is at least twice as large as the diameter of the connecting piece, in order to be able to easily cope with the torque exerted by the screw closure.
- this arrangement of the screw cap has the advantage that the screw cap is arranged at a point at which the respective bag side is bordered on three sides, namely the long sides and the upper edge by the resistance of the relevant bag side increasing sealing proximity. Even at high torques, the composite film does not tend, or only to a tolerable extent, to warp. Depending on the distance between the sealing seams and the sealing flange of the screw cap, the film thickness of the composite film can therefore be reduced further.
- a stand-up pouch according to the invention is shown in a perspective view in FIG.
- the stand-up pouch consists of a heat-sealable composite film 1, in the exemplary embodiment shown here of an aluminum film which is plastic-coated on both sides.
- the inner, sealable plastic layer is designated by the reference number 10, while the aluminum layer has the reference number 11 and the outer plastic layer has the reference number 12.
- the bag has a front side 2 and a rear side not shown in FIG. 1. At the lower end of the bag, a bottom 3 is inserted, which is connected to the front 2 and the back via sealing seams 4. Above the bottom 3, the front 2 and the back are also connected to one another via sealing seams 5. Sealing the front 2, the bottom 3 and the Back is done in the conventional way under the influence of heat and pressure.
- a resealable removal opening 6 is provided in the upper region of the bag, which, as better shown in FIG. 2, has a connecting piece 7 which penetrates the bag or its front side 2 and projects outwards inner end is fixed with a sealing flange 8 on the inside 9 of the bag.
- the removal opening 6 is designed as a screw closure
- the connector 7 has an external thread which can be brought into engagement with an internal thread of a releasable screw cap 13.
- the screw cap is attached to the front 2 of the bag by sealing the composite film 1 with its sealable plastic layer 10 onto the sealing flange 8 of the screw cap.
- the outer edge 14 of the sealing flange 8 is bevelled in such a way that it together with the associated bag side, i.e. the front 2 forms a radially outwardly opening, V-shaped circumferential groove 15.
- the angle of inclination ⁇ of the edge 14 is preferably 45 °.
- the plastic layer 10 is melted. Part of the melted plastic layer reaches radially outwards and fills the circulation groove 15. Because of the V shape the circumferential groove 15 creates a converging gap from which the melted plastic material is sucked. This creates a particularly intimate connection between the outer edge 14 of the sealing flange 8 and the composite film 1.
- the diameter D of the sealing flange 8 is at least twice as large as the diameter d of the socket 7. In the exemplary embodiment shown here, the diameter D is even approximately 2.5 times as large.
- the screw closure is closed by screwing the screw cap 13 onto the socket 7, a torque is generated which must be transmitted through the sealing flange 8 to the front 2 of the stand-up pouch.
- the radial distance from the outer edge of the sealing flange to the center of the screw closure 6 is as large as possible. This can be achieved, on the one hand, by choosing the diameter D of the sealing flange 8 to be large, but an effective effect is only achieved if it can be ensured that the sealing flange 8 is also firmly connected to the composite film 1 at its outer edge 15 . Otherwise the choice of a large diameter D is of little use.
- Stand-up pouches of this type can be used in particular for filling liquids of all kinds.
- the screw cap of the screw cap can of course also have a safety ring in a known manner, so that it can be recognized whether the screw cap has already been opened.

Abstract
Description
Die Erfindung bezieht sich auf einen Standbeutel aus einer heißsiegelfähigen Folie, mit einer Vorderseite und einer Rückseite, die an ihren Rändern miteinander verbunden sind, wobei in der Vorder- oder der Rückseite ein wiederverschließbarer Schraubverschluß vorgesehen ist, der einen Stutzen aufweist, an dem ein Gewinde aufgebracht ist, das sich mit einem Gewinde einer lösbaren Schraubkappe in Eingriff befindet.The invention relates to a stand-up pouch made of a heat-sealable film, with a front and a back, which are connected to one another at their edges, wherein a resealable screw closure is provided in the front or the back, which has a connection piece on which a thread is applied, which is in engagement with a thread of a releasable screw cap.
Sogenannte Einweg-Beutel sind aus der Praxis mehrfach bekannt. Sie werden beispielsweise zum Abfüllen von Getränken eingesetzt, wobei es sich dabei häufig um Portionsbeutel handelt, d.h. mit einer Inhaltsmenge, die von dem Konsumenten bei einer Gelegenheit verzehrt wird. Solche Beutel weisen in der Regel an ihrer Vorderseite eine Schwächungsstelle auf, die mit einem Trinkhalm durchstochen werden kann, wobei der Inhalt des Beutels auch über den Trinkhalm entnommen wird. Es ist auch üblich, je nach Fülssigkeitsinhalt der Beutel, diese Beutel aufzuschneiden, um so den Inhalt entleeren zu können. Beutel dieser Art können leicht entsorgt werden da sie nur ein geringes Volumen beanspruchen. Der Konsument ist jedoch gezwungen, stets den ganzen Beutel leerzutrinken oder im Falle des Abfüllens von nicht trinkbarer Flüssigkeit den Beutel zu entleeren, da Beutel dieser Art nicht wiederverschließbar sind.So-called disposable bags are known several times in practice. They are used, for example, to fill beverages, which are often sachets, ie with an amount of content that is consumed by the consumer on one occasion. Such bags generally have a weakening point on their front side which can be pierced with a drinking straw, the contents of the bag also being removed via the drinking straw. It is also common, depending on the volume of the bags, to cut these bags open so that the contents can be emptied. Bags of this type can be disposed of easily since they take up only a small volume. However, the consumer is forced to always empty the entire bag or to empty the bag in the case of filling non-drinkable liquid, since bags of this type are not resealable.
Ein Standbeutel der eingangs genannten Art ist aus der DE-OS 17 86 019 bekannt. Dieser Beutel weist einen auf der Flachseite angebrachten Schraubverschluß auf, der mit seinem Flansch auf der Außenseite des Beutels befestigt ist. Bei solchen Standbeuteln kann es zu Undichtigkeiten am Verschluß kommen; die beim Wiederverschließen des Schraubverschlusses auftretenden , mitunter hohen Momente können zu einer Beschädigung führen.A stand-up pouch of the type mentioned is known from DE-OS 17 86 019. This bag has a screw cap attached to the flat side, which is attached with its flange to the outside of the bag. With such stand-up pouches, leaks can occur at the closure; the sometimes high moments that occur when the screw cap is closed again can lead to damage.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Standbeutel der eingangs genannten Art zu schaffen, bei dem der Stutzen derart an dem Beutel befestigt ist, daß die Befestigung den durch das Aufschrauben und Abschrauben der Schraubkappe hervorgerufenen Kräften wiedersteht, ohne daß der Beutel undicht wird.It is therefore an object of the present invention to provide a stand-up pouch of the type mentioned at the outset, in which the connecting piece is fastened to the pouch in such a way that the fastening withstands the forces caused by screwing on and unscrewing the screw cap without the pouch becoming leaky.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Stutzen des Schraubverschlusses den Beutel durchsetzt und an seinem inneren Ende mit einem Siegelflansch an der Innenseite des Beutels befestigt ist, daß der Siegelflansch einen abgeschrägten äußeren Rand aufweist, der zusammen mit der zugehörigen Beutelseite eine sich radial nach außen öffnende, V-förmige Umlaufnut bildet, die zumindest teilweise durch die beim Siegeln aufgeschmolzene Siegelschicht geschlossen ist.This object is achieved in that the socket of the screw cap passes through the bag and is attached at its inner end with a sealing flange on the inside of the bag, that the sealing flange has a bevelled outer edge, which together with the associated side of the bag a radially after forms an externally opening, V-shaped circumferential groove which is at least partially closed by the sealing layer melted during sealing.
Zwar ist aus der US-PS 45 42 530 ein flexibler Behälter mit einem Zapfhahn bekannt, bei dem der Stutzen für den Zapfhahn von der Innenseite des Beutels her an einer Beutelwand befestigt ist. Gleichwohl ist auch diese Art der Befestigung nicht geeignet, die beim Aufschrauben bzw. Abschrauben einer Schraubkappe auftretenden Kräfte aufzunehmen, was bei dem Beutel dieser gattungsfremden Entgegenhaltung auch nicht nötig ist, da dort ein Dosierhahn vorgesehen ist, bei dem wesentlich geringere Kräfte wirken. Durch die erfindungsgemäß Lösung konnte auf überraschende Weise eine besonders gute Stabilität der durch das Aufschrauben bzw. Abschrauben der Schraubkappe verursachten Drehmomente in die Vorder- bzw. Rückseite des Beutels erreicht werden. Durch den abgeschrägten Rand und die daduch gebildete V-förmige Nut wird beim Aufsiegeln des Siegelflansches an die Verbundfolie des aufgeschmolzene Material in der Nut gesammelt, so daß besonders an dem Rand des Siegelflansches eine gute Verbindung zum Beutel hergestellt wird. Das ist besonders deswegen wichtig, da über den Rand des Siegelflansches die durch den Schraubverschluß erzeugten Drehmomente sauber in die Vorder- bzw. Rückseite des Folienbeutels eingeleitet werden. Günstig ist auch, wenn die Folienstärke und die Flanschgröße aufeinander abgestimmt sind.Although a flexible container with a tap is known from US-PS 45 42 530, in which the nozzle for the tap from the inside of the bag is attached to a bag wall. Nevertheless, this type of attachment is also not suitable for absorbing the forces that occur when screwing or unscrewing a screw cap, which is also not necessary in the case of this non-generic document, since a metering tap is provided there, in which much less Forces work. The solution according to the invention surprisingly achieved particularly good stability of the torques caused by screwing or unscrewing the screw cap into the front or back of the bag. Due to the bevelled edge and the V-shaped groove formed as a result, when the sealing flange is sealed onto the composite film, the melted material is collected in the groove, so that a good connection to the bag is produced, in particular at the edge of the sealing flange. This is particularly important because the torques generated by the screw cap are introduced cleanly into the front or back of the film bag over the edge of the sealing flange. It is also beneficial if the film thickness and the flange size are coordinated.
Als besonders günstig hat sich herausgestellt, wenn der Neigungswinkel der Abschrägung etwa 45° beträgt.It has proven to be particularly favorable if the angle of inclination of the bevel is approximately 45 °.
Insbesondere für dünnere Verbundfolien ist es von Vorteil, wenn der Durchmesser des Siegelflansches mindestens doppelt so groß ist wie der Durchmesser des Stutzens, um das von dem Schraubverschluß ausgeübte Drehmoment problemlos zu verkraften.For thinner composite films in particular, it is advantageous if the diameter of the sealing flange is at least twice as large as the diameter of the connecting piece, in order to be able to easily cope with the torque exerted by the screw closure.
Ferner ist es günstig, wenn der Beutel mit einem eingesetzten, unteren Boden ausgebildet ist und der Schraubverschluß im oberen Bereich des Beutels angeordnet ist. Neben der einfacheren Entnahmemöglichkeit hat diese Anordnung des Schraubverschlusses den Vorteil, daß der Schraubverschluß an einer Stelle angeordnet ist, an dem die jeweilige Beutelseite an drei Seiten, nämlich den Längsseiten und der Oberkante durch das Widerstandsmoment der betreffenden Beutelseite erhöhende Siegelnähe eingefaßt ist. Auch bei hohen Drehmomenten, die beispielsweise beim erstmaligen Öffnen des Schraubverschlusses auftreten können, neigt die Verbundfolie nicht, oder nur in einem noch erträglichen Maße dazu, sich zu verwerfen. Je nach Abstand der Siegelnähte zum Siegelflansch des Schraubverschlusses läßt sich daher die Folienstärke der Verbundfolie weiter verringern.It is also advantageous if the bag is designed with an inserted, lower bottom and the screw closure is arranged in the upper region of the bag. In addition to the simpler removal option, this arrangement of the screw cap has the advantage that the screw cap is arranged at a point at which the respective bag side is bordered on three sides, namely the long sides and the upper edge by the resistance of the relevant bag side increasing sealing proximity. Even at high torques, the For example, when the screw cap is opened for the first time, the composite film does not tend, or only to a tolerable extent, to warp. Depending on the distance between the sealing seams and the sealing flange of the screw cap, the film thickness of the composite film can therefore be reduced further.
Im Folgenden wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to a drawing.
Es zeigen:
- Fig.1 einen erfindungsgemäßen Standbeutel in einer perspektivischen Ansicht auf dessen Vorderseite und
- Fig.2 eine Schnittansicht durch die Vorderseite des Beutels entlang der Linie II-II aus Fig.1.
- 1 shows a stand-up pouch according to the invention in a perspective view on its front and
- 2 shows a sectional view through the front of the bag along the line II-II from FIG.
In Figur 1 ist in einer perspektivischen Ansicht ein erfindungsgemäßer Standbeutel dargestellt. Der Standbeutel besteht aus einer heißsiegelfähigen Verbundfolie 1, in dem hier gezeigten Ausführungsbeispiel aus einer beidseitig kunststoffbeschichteten Aluminiumfolie. Die innere, siegelfähige Kunststoffschicht ist mit der Bezugsziffer 10 bezeichnet, während die Aluminiumschicht die Bezugsziffer 11 und die äußere Kunststoffschicht die Bezugsziffer 12 trägt. Der Beutel weist eine Vorderseite 2 und eine in Figur 1 nicht näher dargestellte Rückseite auf. Am unteren Ende des Beutels ist ein Boden 3 eingesetzt, der mit der Vorderseite 2 und der Rückseite über Siegelnähte 4 verbunden ist. Oberhalb des Bodens 3 sind die Vorderseite 2 und die Rückseite ebenfalls über Siegelnähte 5 miteinander verbunden. Das Aneinandersiegeln der Vorderseite 2, des Bodens 3 und der Rückseite geschieht in herkömmlicher Weise unter Wärme- und Druckeinwirkung.A stand-up pouch according to the invention is shown in a perspective view in FIG. The stand-up pouch consists of a heat-sealable composite film 1, in the exemplary embodiment shown here of an aluminum film which is plastic-coated on both sides. The inner, sealable plastic layer is designated by the
Wie aus Fig.1 gut erkennbar ist, ist in dem oberen Bereich des Beutels eine wiederverschließbare Entnahmeöffnung 6 vorgessehen, die, wie besser Figur 2 zeigt, einen den Beutel bzw. dessen Vorderseite 2 durchsetzenden und nach außen ragenden Stutzen 7 aufweist, der an seinem inneren Ende mit einem Siegelflansch 8 an der Innenseite 9 des Beutels befestigt ist.As can be clearly seen from FIG. 1, a
Aus Figur 2 ist erkennbar, daß die Entnahmeöffnung 6 als Schraubverschluß ausgebildet ist, wobei der Stutzen 7 ein Außengewinde aufweist, das mit einem Innengewinde einer Lösbaren Schraubkappe 13 in Eingriff bringbar ist.From Figure 2 it can be seen that the
In Figur 2 ist die Schraubkappe im gelösten, d.h. von dem Stutzen 7 abgenommenen Zustand dargestellt.In Figure 2 the screw cap is loosened, i.e. shown from the
Der Schraubverschluß ist an der Vorderseite 2 des Beutels dadurch befestigt, daß die Verbundfolie 1 mit ihrer siegelfähigen Kunststoffschicht 10 auf den Siegelflansch 8 des Schraubverschlusses aufgesiegelt ist.The screw cap is attached to the
Der äußere Rand 14 des Siegelflansches 8 ist in der Weise abgeschrägt ausgebildet, daß er zusammen mit der zugehörigen Beutelseite, d.h. der Vorderseite 2 eine sich radial nach außen öffnende, V-förmige Umlaufnut 15 bildet. Der Neigungswinkel α des Randes 14 beträgt in bevorzugter Weise 45°.The
Beim Aufsiegeln der Verbundfolie 1 auf den Siegelflansch 8 wird die Kunststoffschicht 10 aufgeschmolzen. Ein Teil der aufgeschmolzenen Kunststoffschicht gelangt radial nach außen und füllt die Umlaufnut 15 auf. Aufgrund der V-Form der Umlaufnut 15 entsteht ein konvergierender Spalt, von dem das aufgeschmolzene Kunststoffmaterial angesaugt wird. Dadurch entsteht ein besonders innige Verbindung zwischen dem äußeren Rand 14 des Siegelflansches 8 und der Verbundfolie 1.When the composite film 1 is sealed onto the sealing
Der Durchmusser D des Siegelflansches 8 ist mindestens doppelt so groß wie der Durchmesser d des Stutzens 7. Bei dem hier dargestellten Ausführungsbeispiel ist der Durchmesser D sogar etwa 2,5 Mal so groß.The diameter D of the sealing
Im Folgenden wird die Wirkungsweise der Erfindung beim Öffnen und Schließen des Schraubverschlusses des Standbeutels näher erläutert.The mode of operation of the invention when opening and closing the screw cap of the stand-up pouch is explained in more detail below.
Wenn, ausgehend von dem in Figur 2 gezeigten Zustand, der Schraubverschluß geschlossen wird, indem die Schraubkape 13 auf den Stutzen 7 aufgeschraubt wird, wird ein Drehmoment erzeugt, das durch den Siegelflansch 8 auf die Vorderseite 2 des Standbeutels übertragen werde muß. Um möglichst wenig Verwerfungen in dem Beutel hervorzurufen, und dadurch auftretende Undichtigkeiten zu vermeiden, kommt es besonders darauf an, daß der radiale Abstand des äußeren Randes des Siegelflansches zur Mitte des Schraubverschlusses 6 möglichst groß ist. Das kann zum einen dadurch erreicht werden, daß der Durchmesser D des Siegelflansches 8 groß gewählt wird, wobei ein wirksamer Effekt jedoch nur erzielt wird, wenn gewährleistet werden kann, daß der Siegelflansch 8 auch an seinem äußeren Rand 15 fest mit der Verbundfolie 1 verbunden ist. Ansonsten nutzt die Wahl eines großen Durchmessers D nicht viel.If, starting from the state shown in FIG. 2, the screw closure is closed by screwing the
Durch das Vorsehen der Abschrägung an dem Rand 14 und der dadurch entstehenden Umlaufnut 15 wird erreicht, daß das Kunststoffmaterial der Kunststoffschicht 10 im aufgeschmolzenen Zustand in diese Nut 15 eindringt und dort zu einer innigen Verschweißung zwischen dem äußeren Rand 14 des Siegelflansches 8 und der Kunststoffschicht der Verbundfolie 1 führt. Durch diese Maßnahme wird es wirtschaftlich interessant, Schraubverschlüsse in Standbeuteln vorzusehen, da mit geringem Aufwand ein hohes Maß an Zuverlässigkeit in bezug die Dichtheit des Verschlusses und an Drehmomentfestigkeit der Verbindung zwischen der Verbundfolie 1 und dem Schraubverschluß 6 erreicht wird.By providing the bevel on the
Die beim Öffnen des Schraubverschlusses entstehenden Drehmomente werden auf gleiche Weise von der Vorderseite 2 des Beutels aufgenommen.The torques generated when the screw cap is opened are absorbed in the same way from the
Standbeutel dieser Art lassen sich insbesondere zur Abfüllung von Flüssigkeiten aller Art verwenden.Stand-up pouches of this type can be used in particular for filling liquids of all kinds.
Die Schraubkappe des Schraubverschlusses kann selbstverständlich in bekannter Weise auch noch einen Sicherheitsring aufweist, so daß erkannt werden kann, ob der Schraubverschluß bereits geöffnet worden ist.The screw cap of the screw cap can of course also have a safety ring in a known manner, so that it can be recognized whether the screw cap has already been opened.
