Liner Bags The invention relates to liner bags for Use within supporting cardboard boxes and the like for purging, transporting and cones of biscuits.

In der USA-Patentschrift 3 007 608 sind Auskleidungsbeutel aus Polyaethylen oder anderem dünnwandigen thermoplastischen Material zur Verwendung innerhalb von abstützenden Behältern wie Milchkannen oder Wellpappkartons offenbart. Die Auskleidungsbeutel sind mit einem Zapfschlauch versehen, der mit mechanischen Verbindungsmitteln am Auskleidungsbeutel befestigt ist. Eine ähnliche Konstruktion ist in der USA-Patentsohrift 3 122 297 offenbart, wobei der Auskleidungsbeutel aus mehreren Schichten besteht. Die Dicke des bei solchen Auskleidungen verwendeten Polyaethylens kann in der Größenordnung von 0,038 mm pro Schicht bei Verwendung von mehreren Schichten oder von 0,05 bis 0,076 mm bei Verwendung von nur einer Schicht liegen. Die Auskleidungen können aus Abschnitten von Schlauchware oder Folienware oder Kombinationen daraus gebildet werden, wobei es üblich ist, den Beutel durch Warmschweißung längs der oberen und unteren und, falls gewünscht, auch längs der seitliohen Ränder fertigzustellen. In U.S. Patent 3,007,608, liner bags are made of polyethylene or other thin-walled thermoplastic material for use within supporting containers such as milk cans or corrugated cardboard boxes. The liner bags are provided with a dispensing hose that is attached to the Liner bag is attached. A similar construction is in the United States patent pin No. 3,122,297, wherein the liner bag is made up of multiple layers. The thickness of the polyethylene used in such linings can be on the order of magnitude from 0.038 mm per layer when using multiple layers or from 0.05 to 0.076 mm when using only one layer. The linings can be made from Sections of tubular goods or film goods or combinations thereof are formed it is common practice to heat seal the bag along the upper and lower edges and, if desired, also along the side edges.

Die Erfindung ist darauf gerichtet, an einem derartigen Beutel einen mit einem Flansch versehenen thermoplastischen Nippel oder Ansatz anzubringen, an dem ein Füll- und Zapfschlauch befestigbar ist. Ferner hat die Erfindung zu tun mit den Mitteln zum Anfügen des Flansches eines derartigen Ansatzstücks an das dünne Material der Auskleidung, sowie mit der -Form des Hohlzapfens des Nippels oder Ansatzes, durch die das Aufbringen und Festhalten eines Gummischlauchs auf dem Nippel- erleichtert wird. Die Erfindung ist insbesondere gerichtet auf ein Verfahren, den verhältnismäßig dicken thermoplastischen Flansch des Ansatzes mit dem dünnwandigen, ein- oder mehrschichtigen Material unter Verw-endung einer-zusätzlichen dünnen Lage des Auskleidungsmaterials warm zu verschweißen, wodurch die bislang erforderlichen engen Toleranzen zur Erzielung einer verlässlichen und gleichförmigen Ringabdiohtung vermieden werden und eine zuverlässige Abdichtung mit entsprechender Festigkeit unter Verwendung handelsüblicher Warmschweißgeräte schnell erzi-elbar is-t. The invention is directed to such a bag a to attach a flanged thermoplastic nipple or neck to which a filling and dispensing hose can be attached. Further, the invention has to do with the means for joining the flange of such an extension piece to the thin one Material of the lining, as well as with the shape of the hollow pin of the nipple or neck, which makes it easier to apply and hold a rubber hose on the nipple will. The invention is particularly directed to a method that relatively thick thermoplastic flange of the neck with the thin-walled, single or multilayer Material using an additional thin layer of the lining material to be welded warm, whereby the previously required tight tolerances to achieve a reliable and uniform Ringabdiohtung can be avoided and one reliable sealing with appropriate strength using commercially available Hot welding devices can be built quickly.

H'erner ist die Erfindung auf die Außenform des Hohlzapfens des Nippels gerichtet, die sich so verjüngt, daß ein Stück Gummischlauch oder elastischer Kunststoffschlauch, dessen Innendurchmesser etwa gleich dem des Hohlzapfens ist, auf diesen aufziehbar ist.H'erner is the invention on the outer shape of the hollow pin of the nipple directed, which tapers so that a piece of rubber hose or elastic plastic hose, the inside diameter of which is approximately the same as that of the hollow pin, can be pulled onto it is.

Obige und weitere neuartige Merkmale-der Erfindung ergeben sich aus der folgenden eingehenden Beschreibung eines Ausführungsbeispiels der Erfindung in Verbindung mit der Zeichnung. The above and other novel features of the invention emerge from the following detailed description of an embodiment of the invention in connection with the drawing.

In der Zeichnung bezeichnen gleiche Bezugszeichen gleiche Teile. Dabei sind: Fig. 1 eine perspektivische Ansicht eines Auskleidungsbeutels mit einem Ansatz und daran befestigtem Schlauch, Fig. 2 ein vergrö#erter weggebrochener Schnitt durch Beutel, Ansatz und Schlauch, etwa nach der Linie 2-2 der Fig. 1, Fig. 5 ein vergrößerter Teilschnitt durch Beutel und Ansatz unter schematischer Darstellung der sich gegenüberliegenden Elemente des Warmschweißgeräts, und Fig. 4 eine perspektivische Ansicht, von unten, eines Widerstandsheizelements und des elektrischen Stromkreises. In the drawing, the same reference numerals denote the same parts. 1 shows a perspective view of a liner bag with a Attachment and hose attached to it, FIG. 2 an enlarged, broken-away section through the bag, neck and tube, approximately along the line 2-2 of FIG. 1, Fig. 5 shows an enlarged partial section through the bag and attachment with a schematic representation of the opposing elements of the heat welder, and FIG. 4 is a perspective Bottom view of a resistive heating element and the electrical circuit.

Die Zeichnung zeigt einen mehrschichtigen Auekleidungsbeutel 20, an dem ein mit einem Flansch versehener Nippel oder Ansatz 22 befestigt ist, auf den ein Stück Schlauch 24 aus Gummi oder elastischem Kunststoff aufgezogen ist. Der Beutel kann aus einer Innenschicht 26 in Form eines flachliegenden Kunststoffschlauchabschnitts mit den Seitenfalten 28 und 30 und einer Außenschicht bestehen, die eine bei 34 um die eine Seitenfalte 28 der inneren Schlauchlage herumgefaltete Folie 32 sein kann, deren Seitenkanten 36 und 38 miteinander warmverscliweißt sind, und zwar dicht bei, aber außerhalb der anderen Seitenfalte 30 der Schlauchlage. The drawing shows a multi-layer clothing bag 20, to which a flange provided with a nipple or extension 22 is attached, on a piece of hose 24 made of rubber or elastic plastic is drawn. The bag can consist of an inner layer 26 in the form of a flat plastic tube section with the side gussets 28 and 30 and an outer layer, the one at 34 be around the one side fold 28 of the inner tube layer folded film 32 can, whose side edges 36 and 38 are warmly welded to one another, namely tight at, but outside of the other gusset 30 of the tube layer.

Alle vier Dicken der zwei Lagen können quer über ein Ende der Abschnitte, z.B, bei 42, warmverschweißt werden. All four thicknesses of the two layers can be cut across one end of the sections, e.g. at 42, can be heat-welded.

Nachdem der rohrförmige Nippel- oder Zapfanteil 44 das mit einem Flansch versehenen Nippels von innen durch Öffnungen 46 und 48 in den zwei Lagen der einen Seitenwand so hindurchgesteckt worden ist, daß der Flansch 50 des Nippels oder Ansatzes 22 innerhalb der Schlauchlage 26 liegt, können die vier Dicken der zwei Lagen quer über das andere Ende der Abschnitte, z.B, bei 42, warmverschwçißt werden, so daß der Beutel außer am Nippel und an den Öffnungen 46 und 48, durch die der Nippelzapfen 44 hindurchgeht, dicht ist.After the tubular nipple or pivot portion 44 that with a flange provided nipple from the inside through openings 46 and 48 in the two layers of one Sidewall has been pushed through that the flange 50 of the nipple or neck 22 lies within the tube layer 26, the four thicknesses of the two layers can be transverse over the other end of the sections, e.g., at 42, so that the bag except for the nipple and openings 46 and 48 through which the nipple pin 44 passes through, is tight.

Der Hohlzapfen des Nippels hat eine verhältnismäßig glatte zylindrische Bohrung 23 und eine vom Flansch 50 ausgehende zylindrische Außenfläche 25, die in eine konisch zulauf ende Fläche 27 übergeht, die bis zum Außenende des Zapfens geht und eine verhältnismäßig dünne ringförmige Endwand 29 bildet. Der in dieser Weise ausgebildete Zapfen erleichtert das Aufschieben eines Stücks Gummischlauch 24, dessen Innendurchmesser etwa dem Innendurchmesser des Zapfens entspricht, wobei sich der Schlauch beim Aufziehen auf das sich verjüngende Ende und den zylindrischen Teil leicht dehnt, ohne den Zapfen zusammenzudrücken. Durch Verwendung des sich verjüngenden Endes, dessen Durchmesser sich etwa auf den Innendurchmesser des Schlauchs verringert, und durch Anwendung einer Verjüngung von etwa 100 in bezug auf die Achse wird das Aufschieben eines Stückes Schlauch, dessen Innendurchmesser dem des Zapfens entspricht, auf den Ansatz erleichtert. Wenn der Schlauch so aufgeschoben wird, daß ein wesentlicher Teil des Schlauchs den zylindrischen Teil umgreift, ergibt sich ein Reibsitz, der jeder Tendenz widersteht, beim Füllen der Auskleidung sich zu lösen. The hollow pin of the nipple has a relatively smooth cylindrical Bore 23 and a cylindrical outer surface 25 extending from the flange 50, which is shown in FIG a conically tapered surface 27 passes, which goes to the outer end of the pin and forms a relatively thin annular end wall 29. That way trained pin facilitates the pushing of a piece of rubber hose 24, the The inside diameter corresponds approximately to the inside diameter of the pin, the hose slightly stretches when pulling onto the tapered end and the cylindrical part, without compressing the tenon. By using the tapered end, the diameter of which is reduced to approximately the inner diameter of the hose, and by using a taper of about 100 with respect to the axis that becomes Pushing on a piece of hose, the inside diameter of which corresponds to that of the spigot, relieved on the approach. When the hose is pushed on in such a way that an essential Part of the hose engages around the cylindrical part, there is a friction fit that resists any tendency to loosen as the liner is filled.

In dieser Hinsicht verringert die Möglichkeitw einen Schlauch zu verwenden, dessen Innendurchmesser etwa gleich dem Innendurchmesser des Zapfens ist, den axialen Schub, der beim Füllen zu einem Abrutschen des Schlauches führen könnte. Da keine Querschnittsverengung vorhanden ist, ist die Strömungsgeschwindigkeit der Flüssigkeit durch Schlauch und Nippelbohrung im wesentlichen gleich, sodaß die Strömung am Zapfenende fast keinen statischen Druck erzeugt. Es ist dadurch nicht erforderlich, außen auf dem Zapfen Ringrippen oder Zähne vorzusehen, um die Reibhaftung des Schlauchs zu erhöhen. Die Reibhaftung ist ausreichend, um den Schlauch ohne äußere Abbindung und ohne Verwendung von Klebemitteln und dergleichen auf dem Zapfen zu halten. Durch das Fehlen von Ringrippen oder Zähnen wird der Gummischlauch nicht überbeansprucht.In this regard, it reduces the possibility of using a hose. the inner diameter of which is approximately equal to the inner diameter of the pin, the axial Thrust which could lead to the hose slipping off during filling. There no Cross-sectional constriction is present, is the flow rate of the liquid through hose and nipple bore essentially the same, so that the flow at the spigot end almost no static pressure generated. This means it is not necessary to look outside to provide ring ribs or teeth on the pin in order to increase the friction grip of the hose raise. The friction grip is sufficient to hold the hose without any external binding and to hold on the pin without the use of adhesives and the like. By the lack of ring ribs or teeth does not overstress the rubber hose.

Der Flansch 50 des Nippels 22 hat einen verhEltnismäßig dicken ringförmigen Mittelteil 54 und einen diesen umgebenden dünneren biegeamen Ringteil 56. Wie bereits erwähnt, kann die Dicke jeder der einzelnen Schichten 26 und 32 in der Größenordnung von 0,038 mm liegen, während die Dicke des dünnen biegsamen Ringflanschteils 56 etwa das Zehnfache dieser Dicke sein kann. Ein Schmelzring zwischen den zwei so dünnen Filmen und dem Ringteil 56 des verhältnismäßig dicken Flansches 50 muß notwendigerweise gleichförmig sein, wenn die dadurch erzielte Abdichtung verläßlich und flüssigkeitsdicht sein und die Schicht 26 sicher mit dem Nippelflansch verbinden soll. The flange 50 of the nipple 22 has a relatively thick annular shape Middle part 54 and a thinner, bendable ring part 56 surrounding it. As already mentioned, the thickness of each of the individual layers 26 and 32 can be of the order of magnitude of 0.038 mm, while the thickness of the thin flexible annular flange portion 56 can be about ten times this thickness. A fusion ring between the two like that thin films and the ring portion 56 of the relatively thick flange 50 must necessarily be uniform if the seal obtained thereby is reliable and liquid-tight his and the Layer 26 should securely connect to the nipple flange.

Die Anwendung der richtigen Wärmemenge zur Erzielung der Verschmelzung dünner Filme mit einem wesentlich dickeren Teil hat insofern Schwierigkeiten geboten, als jede geringfügige Schwankung in der Heizwirkung zu schwerwiegender Überhitzung oder Untererwärmung und unvollkommener Verbindung führt.Applying the correct amount of heat to achieve the fusion thin films with a much thicker part has presented difficulties in this respect than any minor variation in heating effect to severe overheating or underheating and imperfect connection.

Zur Erzielung der ringförmigen Verschweißung der Filme mit dem Nippelflansch ohne Gefährdung duroh Überhitzung oder Untererwärmung oder geringfügige Wärme schwankungen längs der Ringbahn der Verschweißung, durch die schwache Stellen entstehen könnten, sieht die Erfindung vor, die die Versohweißung bewirkende Wärme durch eine dritte Schicht von Material zur Anwendung zu bringen, das ähnliche Eigenschaften aufweist wie die Schichten 26 und 32. In der Praxis kann diese dritte Schicht 60 ein kleines quadratisohes, rundes oder sonstwie geformtes Stück Abfallmaterial sein, das ebenso dick wie die Schichten 26 und 32 oder dicker ist. Die dritte Schicht ist mit einer Öffnung 62 versehen, die über den Zapfen 44 des Nippels 22 gestreift wird. Nach Aufbringung der zusätzlichen Schicht 60 wird der Zapfen des Nippels in die Mittelöffnung 64 eines ringförmigen Schmelzschweißelements 66 eingebracht, auf dem die Schicht 60, die Dicken 68 und 70 der Schichten 26 und 32, der Ringteil 56 des Flansches 50, die Dicken 72 und 74 der Schichten 26 und 32 und ein Druckelement 76 mit flacher Druckfläche 78 aufliegen. To achieve the ring-shaped welding of the films with the nipple flange without risk of overheating or underheating or slight heat fluctuations along the ring path of the weld, which could create weak spots, the invention provides that the Versohweißung causing heat by a third To bring layer of material to use that has similar properties like layers 26 and 32. In practice, this third layer 60 can be a small one be a square, round or otherwise shaped piece of waste material, the same thick as layers 26 and 32 or thicker. The third layer is with one Opening 62 is provided which is slipped over the pin 44 of the nipple 22. To Applying the additional layer 60 will pin the nipple into the central opening 64 of an annular fusion welding element 66 introduced on which the layer 60, the thicknesses 68 and 70 of layers 26 and 32, the ring portion 56 of the flange 50, the thicknesses 72 and 74 of the layers 26 and 32 and a pressure element 76 with flat Rest on pressure surface 78.

Das Schmelzschweißelement 66 besteht aus einem Ring 80 aus Nickelchromblech, der gleichmäßig dick und radial gleich breit ist. Der Ring 80 ist eingebettet zwischen dünnen Lagen Glasfasergewebe 82 und 84, die mit Tetrafluoraethylenpolymeren imprägniert sind, wie sie unter dem Warenzeichen 11Teflon" von E. I. du Pont De Nemours & Oo. hergestellt werden. Der Heizstrom wird an sich genau diametral gegenüberliegenden Punkten in den Nickelchromring 80 geleitet, und zwar durch die Leitungen 86 und 88, die an der Unterseite des Rings mit Silberlot befestigt sein können. Die elektrische Widerstandsheizung des Rings 80 wird durch einen Zeitschalter 90 gesteuert, der eine bestimmte Zeitspanne lang Strom fließen läßt-und so die Erwärmung der thermoplastischen Schichten und des Nippelflansches steuert. Die-Wärmezufohr zu den Schichten schmilzt ein ringförmiges Gebiet der Schichten 60, 70 und 68 sowie ein flaches ringförmiges Oberflächengebiet des äußeren Ringteils 56 des Nippelflansches 50, während die verschiedenen Dicken unter Druck gehalten werden. Die von dem geschmolzenen Gebiet radial einwärts und radial auswärts gelegenen Teile der Schichten bleiben kühl und bilden zusammen mit dem ungeschmolzenen Teil des Flansches eine Begrenzungswand um das geschmolzene Ringgebiet. Sofort nach dem Schmelzen wird der Heizetrom abgeschaltet, wo; rauf sich die Wärme des geschmolzenen thermoplastischen Kunststoffs verteilt und dieser in den festen Zustand übergeht als eine homogene ringförmige Masse, die eine Abdichtung und Verbindung zwischen dem Nippelflansch und den Schichten 68, 70 und 60 bildet. Wenn auch die Schicht 60 oder 70 wegen ihrer Nähe zum Nickelchromring einer etwas höheren Erwärmung ausgesetzt sein kann, wird die Verbindung zwischen dem Flansch und der anliegenden Schicht 68 gleichmäßig vollkommen und von hoher Festigkeit sein. Die Notwendigkeit einer lecksicheren Verschweißung zwischen der Schicht 68 und dem Flansch ist offensichtlich. The fusion welding element 66 consists of a ring 80 made of nickel-chrome sheet, which is uniformly thick and radially equally wide. The ring 80 is embedded between thin layers of fiberglass fabrics 82 and 84 impregnated with tetrafluoroethylene polymers are as they are under the trademark 11Teflon "by E. I. du Pont De Nemours & Oo. getting produced. The heating current is in itself exactly diametrically opposite Points passed into the nickel chrome ring 80, through lines 86 and 88, which can be attached to the underside of the ring with silver solder. The electric Resistance heating of the ring 80 is controlled by a timer 90 which one Lets current flow for a certain period of time - and so does the warming of the thermoplastic layers and the nipple flange. Die-heat supply an annular area of layers 60, 70 and 68 as well as melts to the layers a flat annular surface area of the outer ring portion 56 of the nipple flange 50 while the various thicknesses are held under pressure. The ones from the melted one Radially inward and radially outward areas of the layers remain cool and together with the unmelted part of the flange form a boundary wall around the molten ring area. Immediately after melting, the heating electricity is switched off, Where; The heat from the melted thermoplastic is distributed over it and this goes into the solid state as a homogeneous ring-shaped mass that a seal and connection between the nipple flange and the layers 68, 70 and 60 forms. Even if the layer 60 or 70 because of its proximity to the nickel-chrome ring the connection between the flange and the adjacent layer 68 uniformly perfect and of high Be firm. The need for a leak-proof weld between the Layer 68 and the flange is evident.

Das Vorhandensein der Schicht 70 trägt bei zur Erreicung dieser Abdichtung, und die Gleichförmigkeit der ringförmigen Schmelz zone zwischen den Schichten 68 und 70 kann durch die Schicht 60 verbessert werden. Die Schicht 60 kann weggelassen werden, wobei dann allein die Schicht 70 dazu dient, die lecksichere Abdichtung zwischen der Schicht 68 und dem Flansch sicherzustellen.The presence of layer 70 helps achieve this seal, and the uniformity of the annular melt zone between the layers 68 and 70 can be enhanced by layer 60. Layer 60 can be omitted are, in which case only the layer 70 is used to provide the leak-proof seal between the layer 68 and the flange.

Die Schmelztemperatur des thermoplastischen Kunststoffs der Schichten 60, 68 und 70 sowie des Nippelflansches liegt wesentlich unter der Schaelztemperatur der mit teflon imprägnierten Glasfaserlage 82, so daß keine Tendenz besteht, daß die geschmolzene Zone irgendwie an dem mit Teflon überzogeneneHeizelement haftet. The melting temperature of the thermoplastic of the layers 60, 68 and 70 as well as the nipple flange is significantly below the peeling temperature the fiberglass sheet 82 impregnated with Teflon so that there is no tendency that the melted Zone somehow on the heating element covered with Teflon adheres.

Der eigentliche Schmelzvorgang kann in einem Bruchteil einer Sekunde erfolgen, und die zur Wiederherstellung des festen Zustandes erforderliche Wärmeableitung erfolgt in nur wenigen Sekunden, so daß das ganze Arbeitsspiel zur Herstellung einer Verschweißung nur eine Sache von-Sekunden ist. The actual melting process can take place in a fraction of a second and the heat dissipation required to restore the solid state takes place in just a few seconds, so that the whole work cycle to produce a Welding is only a matter of seconds.

Beim Abpacken von Milch, wobei sanitäre Normen zu erfüllen sind, ist es verhältnismäßig einfach, wenn die Auskleidung erst einmal mit einem Nippel versehen und unter sanitären Bedingungen geschlossen worden ist, den Nippel unter sani tären Bedingungen mit dem Beutel zu verschweißen und danach ein Ende eines Schlauchstücks, dessen anderes Ende geschlossen ist, auf den Zapfen des Nippele aufzuschieben, während der sanitäre Zustand innerhalb der Auskleidung erhalten bleibt. When packing milk, whereby sanitary standards must be met, It is relatively easy once the liner is fitted with a nipple provided and closed under sanitary conditions, the nipple underneath sanitary conditions to weld the bag and then one end of one Hose piece, the other end of which is closed, onto the spigot of the nipple postpone while maintaining the sanitary condition within the liner.

Nachdem eine derartige Auskleidung in einen abstützenden Behälter, z. B. einen Karton oder eine Milehkanne, eingesetzt worden ist, kann sie unter Druck mittels des Schlauchs und des Nippels schnell gefüllt werden, bis sie mit den Innenwänden des Behälters in abstützende Berührung kommt. nas Füllen kann mit einem Gerät erfolgen, wie es in der kanadischen Patentschrift 688 591 oder der USA-Patentschrift 3 108 901 offenbart ist. After such a liner is placed in a supporting container, z. B. a cardboard box or a milk jug, has been used, it can be under pressure by means of the hose and the nipple are quickly filled until they are flush with the inner walls of the container comes into supporting contact. nas filling can be done with a device, as in Canadian Patent 688,591 or U.S. Patent 3,108 901 is disclosed.
