Abstract

Thermoplastic masses which tend to be sticky are cast in vessels having partitions (15, 16) which allow the mass to be removed in individual pieces (11 to 14). The partitions contain a corrugated cardboard core (30) and an outer surface made of silicone-treated paper (31, 32). Furthermore, the partitions have slots (25, 26) which allow them to be fitted together in the form of a star. At its top edge (22), the paper of the partitions is also perforated so that heated air inside the partitions can escape. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Verpackung für klebrige thermoplastische Massen sowie auf ein Verfahren zum Abpacken derartiger thermoplastischer Massen, wie Asphalt, Bitumen, Teer, thermoplastische Markierungsmassen zur Herstellung von Fahrbahnlinien und dergleichen.The invention relates to a packaging for sticky thermoplastic compositions and to a method for packaging such thermoplastic compositions, such as asphalt, bitumen, tar, thermoplastic marking compositions for the production of lane lines and the like.

Thermoplastische Massen der vorgenannten Art werden vor ihrer Anwendung erhitzt und dann in Fugen, Nuten oder flachen Ausfräsungen in oder auf Fahrbahndecken ein- oder aufgebracht. Die Haftneigung solcher thermoplastischer Massen hängt stark von ihrer Temperatur ab, so daß man morgens in nördlichen Gebieten keine Schwierigkeiten hat, die Masse aus ihrem Versandgefäß herauszulösen und zum Einschmelzen zu zerkleinern, während dies in südlichen Ländern mit Problemen verbunden ist.Thermoplastic compositions of the aforementioned type are heated before use and then inserted or applied in joints, grooves or flat cutouts in or on road surfaces. The tendency of such thermoplastic compositions to stick strongly depends on their temperature, so that in the morning in northern areas it is not difficult to remove the composition from its shipping container and to comminute it, whereas in southern countries this is problematic.

Es ist bereits eine Verpackung für klebrige thermoplastische Massen bestehend aus einem Behälter mit Trennwänden bekannt (US-A-2 352 865), wobei der Zusammenhalt der Massenstücke dadurch gelöst wird, daß der Blechmantel des Behälters entlang einer senkrechten Linie aufgetrennt und der Mantel dann abgewickelt wird. Dies ist offenbar nur möglich, wenn der Behälter keinen Boden hat.A packaging for sticky thermoplastic compositions consisting of a container with dividing walls is already known (US-A-2 352 865), the cohesion of the mass pieces being released by separating the sheet metal jacket of the container along a vertical line and then unwinding the jacket becomes. Obviously this is only possible if the container has no bottom.

In der Praxis werden Fässer mit Boden zum Versand der erwähnten Massen verwendet, und man löst den Boden mit einer Axt, ebenso wie man den Schnitt entlang einer senkrechten Mantellinie des Fasses herstellt. Diese Arbeiten sind mühsam und können nicht sauber ausgeführt werden.In practice, barrels with a bottom are used to send the masses mentioned, and the bottom is loosened with an ax, just as the cut is made along a vertical surface line of the barrel. This work is tedious and cannot be carried out cleanly.

Zur Erleichterung des Herauslösens von Bitumen aus dem zugehörigen Gefäß ist es bereits bekannt (DE-GM 63 34 605), den Boden des Gefäßes abtrennbar zu gestalten und den Blechmantel des Gefäßes entlang der Schweißnaht aufzureißen. Die Innenseiten des Blechmantels und des Bodens sind mit einer Schicht aus Silikon oder Polytetrafluorethylen versehen, welches Material bekanntlich ein abweisendes Verhalten gegenüber Klebstoffen besitzt. Es ist auch schon bekannt, dabei einen Trennsteg mit einer Schicht aus Silikon oder Polytetrafluorethylen in Achsrichtung des Gefäßes einzulegen, so daß man beim Aufreißen des Gefäßes die Bitumenmasse in zwei Stücken erhält.To facilitate the removal of bitumen from the associated vessel, it is already known (DE-GM 63 34 605) to make the bottom of the vessel detachable and to tear open the sheet metal jacket of the vessel along the weld seam. The inside of the sheet metal jacket and the bottom are provided with a layer of silicone or polytetrafluoroethylene, which material is known to have a repellent behavior towards adhesives. It is also known to insert a separating web with a layer of silicone or polytetrafluoroethylene in the axial direction of the vessel, so that the bitumen mass is obtained in two pieces when the vessel is torn open.

Die Herstellung dieses Trennstegs ist jedoch mit Schwierigkeiten verbunden. Verbundmaterial aus einem Kunststoffträger und einer Schicht aus Silikon oder Polytetrafluorethylen ist äußerst teuer und verbietet sich deshalb zur Anwendung als Trennhilfe. Wenn man Pappe oder Karton mit Silikon besprüht, so dringt dieses ungleichmäßig ein mit der Folge, daß der Trenneffekt ungleichmäßig ist und die Gefahr heraufbeschworen wird, die Masse mit Pappe zu verunreinigen.However, the manufacture of this separator is difficult. Composite material made of a plastic carrier and a layer of silicone or polytetrafluoroethylene is extremely expensive and is therefore not suitable for use as a separation aid. If cardboard or cardboard is sprayed with silicone, it penetrates unevenly, with the result that the separating effect is uneven and the risk is raised of contaminating the mass with cardboard.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Verpackung zur Aufnahme von thermoplastischen Massen und ein Verfahren zum Abpacken in Behältern anzugeben, das sich bequem, wirtschaftlich und mit hoher Zuverlässigkeit einsetzen läßt, auch hinsichtlich des Herauslösens der thermoplastischen Masse.The invention is therefore based on the object of specifying packaging for holding thermoplastic compositions and a method for packaging in containers which can be used conveniently, economically and with high reliability, also with regard to the removal of the thermoplastic composition.

Nach der Erfindung besteht der zylinder- oder kegelstumpfförmige Mantel des Behälters aus Blech und ist mit einem achsparallel verlaufenden Aufreißstreifen versehen, sein Boden und gegebenenfalls vorhandener Deckel sind leicht vollständig lösbar, seine Innenwände sind mit silikonisiertem Papier ausgekleidet und jede Trennwand besteht aus einem Kern aus Wellpappe, der mit silikonisiertem Papier vollständig abgedeckt ist.According to the invention, the cylindrical or truncated cone-shaped jacket of the container is made of sheet metal and is provided with a tear strip running parallel to the axis, its bottom and any lid which may be present are easily completely detachable, its inner walls are lined with siliconized paper and each partition consists of a core of corrugated cardboard completely covered with siliconized paper.

Es werden also Blechgefäße verwendet, die je einen lösbaren Boden und Deckel sowie eine an vorbereiteter Stelle auftrennbar Mantelwand aufweisen, ferner Trennwände aus einem Stabilisierungskern und einem Mantel aus silikonisiertem Papier.Sheet metal vessels are thus used, each of which has a detachable base and lid and a jacket wall which can be separated at a prepared location, and also partition walls made of a stabilizing core and a jacket made of siliconized paper.

Silikonisiertes Papier ist in guter, gleichmäßiger Qualität von verschiedenen Herstellern erhältlich, und läßt sich ausreichend gut von der vergossenen thermoplastischen Masse lösen. Die Wandstärke von Papier ist andererseits weitaus nicht ausreichend, die verflüssigte Masse zuverlässig voneinander zu trennen. Man verwendet deshalb Trennwände, die einen Stabilisierungskern und einen Mantel aus silikonisiertem Papier enthalten.Siliconized paper is available in good, uniform quality from various manufacturers, and can be detached from the cast thermoplastic compound sufficiently well. On the other hand, the wall thickness of paper is far from sufficient to reliably separate the liquefied mass from one another. Partitions are therefore used which contain a stabilizing core and a jacket made of siliconized paper.

Nach dem Herauslösen der thermoplastischen Masse aus dem Gefäß oder dem Behälter, in dem es gegossen worden ist, werden zylindrische Stücke mit kreissegmentartigem Grundriß erhalten, die sich relativ bequem weiter zerteilen lassen, um den Wiederaufschmelzvorgang der Masse vor ihrer Anwendung zu beschleunigen. Dies trifft auch bei der Handhabung der Stücke in heißen klimaten zu, in welchen sonst größere Brocken an thermoplastischer Masse, wie diese nach Herauslösen aus üblichen Gefäßen von etwas mehr als 30 l Fassungsvermögen entstehen, wegen ihrer Klebrigkeit kaum zerteilt werden können. Da mit der Erfindung vier oder sechs oder noch mehr längliche thermoplastische Massenstücke erhalten werden, können diese mittels Axt oder Buschmesser zerteilt werden, auch wenn wegen der Umgebungstemperatur bereits eine gewisse Klebrigkeit und Zähigkeit der Masse gegeben sein sollte.After the thermoplastic mass has been removed from the vessel or the container in which it has been poured, cylindrical pieces with a segment-like outline are obtained which can be relatively easily divided further in order to accelerate the remelting process of the mass before it is used. This also applies to the handling of the pieces in hot climates, in which otherwise larger chunks of thermoplastic mass, such as those that arise after being removed from conventional vessels of a little more than 30 l capacity, can hardly be broken up because of their stickiness. Since four or six or even more elongated thermoplastic bulk pieces are obtained with the invention, these can be cut up by means of an ax or bush knife, even if a certain stickiness and toughness of the mass are already due to the ambient temperature should be given.

Fig. 1 zeigt ein mit thermoplastischer Masse gefülltes Gefäß, dessen Inneres 1 als ein umgrenzter Raum aufzufassen ist. Das Gefäß enthält einen rechteckförmigen oder leicht trapezförmigen Blechmantel 2 , der entlang einer Schweißnaht 3 zu einem geschlossenen Ring gefertigt ist, und einen Deckel 4 sowie einen Boden 5. Der Deckel 4 und der Boden 5 sind an dem Blechmantel 2 mittels Spannbändern 6 befestigt, die um Flanschränder des Mantels 2 und des Deckels 4 bzw. 5 gelegt sind, wie am besten aus der Schnittdarstellung in Fig. 2 ersichtlich. Die Enden der Spannbänder 6 übergreifen einander, wobei eine Lasche 7 gebildet ist, die man mit einem Schraubenzieher oder dergleichen anheben und mit einer Zange abziehen kann, um das Spannband 6 zu lösen.1 shows a vessel filled with thermoplastic material, the interior 1 of which is to be understood as a delimited space. The vessel contains a rectangular or slightly trapezoidal sheet metal jacket 2, which is made along a weld 3 to form a closed ring, and a lid 4 and a bottom 5. The lid 4 and the bottom 5 are fastened to the sheet metal jacket 2 by means of straps 6, which are placed around the flange edges of the casing 2 and the cover 4 or 5, as can best be seen from the sectional view in FIG. 2. The ends of the tensioning straps 6 overlap one another, forming a tab 7 which can be lifted with a screwdriver or the like and pulled off with a pair of pliers in order to release the tensioning strap 6.

Beim Verschweißen des Blechmantels 2 entlang der Naht 3 entstehen Schwächungszonen 8, die normalerweise einen bestimmten Abstand zur Naht 3 haben, beispielsweise 3 mm. Der Beginn dieser Schwächungszonen ist mit Kerben 9 markiert, so daß ein Lappen am oberen Rand des Blechmantels 2 gebildet ist, den man mit einer Zange ergreifen kann, um einen Blechstreifen 10 vollständig abzuziehen, wodurch der Blechmantel geöffnet wird und sein Inneres - eine Portion erkalteter Masse - zutage tritt.When the sheet metal jacket 2 is welded along the seam 3, weakening zones 8 arise, which are normally at a certain distance from the seam 3, for example 3 mm. The beginning of these weakening zones is marked with notches 9, so that a rag is formed at the upper edge of the sheet metal jacket 2, which can be grasped with a pair of pliers to completely pull off a sheet metal strip 10, whereby the sheet metal jacket is opened and its interior - a portion cooled down Mass - comes to light.

Die Portion ist in vier Stücke 11, 12, 13, 14 unterteilt, was man mit Hilfe zweier Trennwände 15, 16 (Fig. 3) erreicht. Die Trennwände 15, 16 besitzen jeweils Seitenkanten 21 bis 24, die so verlaufen, daß sie in das Innere des Gefäßes (Fig. 1) passen. Die Kanten 21 und 22 sind deshalb im allgemeinen parallel zueinander, während die Kanten 23 und 24 im Fall eines zylindrischen Gefäßes parallel sind, im Falle eines leicht konischen Gefäßes aber eine entsprechende Neigung zueinander haben. Im letzteren Fall kann man den Umriß der Trennwände 15,16 als trapezförmig bezeichnen. Die Trennwand 15 besitzt noch einen Schlitz 25, der sich von der Mitte der Seitenkante 21 in axialer Richtung bis etwa zur Hälfte der Distanz zur Kante 22 erstreckt. Ein gleichartiger Schlitz 26 ist in der Trennwand 16 angebracht, dieser erstreckt sich aber von der Kante 22 in Richtung auf die Kante 21. Die Summe der Längen der Schlitze 25 und 26 entspricht dem Abstand der Kanten 21 und 22 voneinander. Die Trennwände 15, 16 sind aufgrund dieser Schlitze 25, 26 zur Bildung eines Kreuzes oder Sterns zusammengesteckt. Es versteht sich, daß man noch mehr Trennwände auf diese Weise zusammenstecken kann, um eine Unterteilung in mehr als vier Sektoren zu erzielen.The serving is in four pieces 11, 12, 13, 14 divided what can be achieved with the help of two partitions 15, 16 (Fig. 3). The partitions 15, 16 each have side edges 21 to 24, which extend so that they fit into the interior of the vessel (Fig. 1). The edges 21 and 22 are therefore generally parallel to one another, while the edges 23 and 24 are parallel in the case of a cylindrical vessel, but have a corresponding inclination to one another in the case of a slightly conical vessel. In the latter case, the outline of the partitions 15, 16 can be described as trapezoidal. The partition wall 15 also has a slot 25, which extends from the center of the side edge 21 in the axial direction to approximately half the distance to the edge 22. A similar slot 26 is made in the partition 16, but this extends from the edge 22 towards the edge 21. The sum of the lengths of the slots 25 and 26 corresponds to the distance of the edges 21 and 22 from each other. The partitions 15, 16 are plugged together due to these slots 25, 26 to form a cross or star. It is understood that even more partitions can be put together in this way to achieve a division into more than four sectors.

Der umgrenzte Raum 1 kann eine Auskleidung aus siliconisiertem Papier enthalten, die aus einem Bodenabschnitt 17 und einem Seitenwandabschnitt 18 besteht. Der Bodenabschnitt 17 entspricht in seiner Form und Abmessung dem Boden 5, ist also im allgemeinen kreisrund. Der Seitenwandabschnitt 18 besteht aus einem rechteckförmigen oder trapezförmigen Papierblatt, dessen Ränder sich entlang eines Streifens 19 überlappen.The bounded space 1 may include a siliconized paper liner consisting of a bottom portion 17 and a side wall portion 18. The bottom section 17 corresponds in shape and dimension to the bottom 5, so it is generally circular. The side wall section 18 consists of a rectangular or trapezoidal sheet of paper, the edges of which overlap along a strip 19.

Die Trennwände 15, 16 enthalten jeweils einen Stabilisierungskern 30 (Fig. 4), der von einem Mantel aus silikonisiertem Papier umgeben ist. Zweckmäßigerweise werden ein erstes Papierblatt 31 entsprechend der Form und dem Umriß des Stabilisierungskernes 30 und ein zweites Papierblatt 32 mit etwas Übermaß verwendet. Dieses Übermaß bildet Randstreifen 33, die an den Ecken etwas eingeschnitten sind, wie bei 34 in Fig. 4 dargestellt, so daß man diese Randstreifen 33 umschlagen und über den Rand des Papierblattes 31 kleben kann.The partitions 15, 16 each contain a stabilizing core 30 (FIG. 4), which is surrounded by a jacket made of siliconized paper. A first paper sheet 31 corresponding to the shape and the outline of the stabilizing core 30 and a second paper sheet 32 with a little oversize are expediently used. This excess forms edge strips 33, which are slightly cut at the corners, as shown at 34 in Fig. 4, so that one can fold these edge strips 33 and glue them over the edge of the paper sheet 31.

Der Stabilisierungskern 30 besteht aus Karton oder Pappe, insbesondere wird Wellpappe bevorzugt, die je eine äußere Deckschicht und eine mittlere Wellungslage aufweist. Dadurch werden bekanntlich Wellungsberge und Wellungstäler gebildet, die in Fig. 4 bei 35 gestrichelt angedeutet sind. Die Wellenberge bzw. -täler 35 laufen parallel zu dem Schlitz 25 bzw. 26. Auf der Oberseite der Trennwände 15, also entlang der Randkanten 22, sind ferner Belüftungsöffnungen 36 angebracht, d. h. das Papierblatt 32 wird im Bereich des Umschlags 33 perforiert.The stabilizing core 30 consists of cardboard or cardboard, in particular corrugated cardboard is preferred, each having an outer cover layer and a middle corrugated layer. As is known, this creates corrugation peaks and valleys, which are indicated by dashed lines in FIG. 4 at 35. The wave peaks or troughs 35 run parallel to the slot 25 or 26. On the upper side of the partition walls 15, that is to say along the peripheral edges 22, ventilation openings 36 are also provided, i. H. the paper sheet 32 is perforated in the area of the envelope 33.

Zur Füllung der Gefäße geht man wie folgt vor:
Die Auskleidung 17, 18 wird ins Innere des Gefäßes eingesteckt. Daraufhin wird der aus den zusammengesteckten Trennwänden 15, 16 gebildete Stern ins Innere des Gefäßes geschoben und mittels eines über den Rand des Gefäßes gelegten Gewichts beschwert. Daraufhin wird heißflüssige Masse, die man in einem Vorratsbehälter bereithält, in das Gefäß eingefüllt, wobei man auf eine Verteilung in den vier Sektoren achtet. Die Trennwände 15, 16 erhitzen sich dabei stark, so daß sich die Luft im Inneren der Trennwände ausdehnt, jedoch über die Belüftungsöffnungen 36 entweichen kann. Auf diese Weise wird erreicht, daß der Auftrieb der Trennwände 15, 16 nicht übermäßig groß wird und diese ihre Form beibehalten können. Wenn das Innere des Gefäßes in der vorgesehenen Weise gefüllt worden ist, wird die Masse erkalten lassen. Dabei bilden sich Massenstücke 11, 12, 13, 14 entsprechend den Kammern zwischen den Gefäßwänden 2, 5 und den Trennwänden 15, 16. Diese Massenstücke 11 bis 14 sind durch die Trennwände 15, 16 sowohl voneinander getrennt als auch miteinander zusammenhängend verbunden.Proceed as follows to fill the vessels:
The lining 17, 18 is inserted into the interior of the vessel. Thereupon the star formed from the assembled partition walls 15, 16 is pushed into the interior of the vessel and weighted by means of a weight placed over the edge of the vessel. Hot liquid mass, which is kept in a storage container, is then poured into the vessel, paying attention to a distribution in the four sectors. The partitions 15, 16 heat up strongly, so that the air expands inside the partitions, but can escape through the ventilation openings 36. In this way it is achieved that the buoyancy of the partition walls 15, 16 does not become excessively large and they can maintain their shape. When the inside of the vessel has been filled as intended, the mass is allowed to cool. Mass pieces 11, 12, 13, 14 are formed in accordance with the chambers between the vessel walls 2, 5 and Partitions 15, 16. These bulk pieces 11 to 14 are separated by the partitions 15, 16 from each other and connected together.

Die gefüllten Gefäße werden zu dem Endverbraucher gesandt. Vor Gebrauch öffnet der Endverbraucher die Gefäße, indem er die Spannbänder 6 löst und den Nahtstreifen 10 abreißt. Die Massenstücke 11 bis 14 liegen dann frei, sind aber noch durch die Trennwände zusammengehalten. Dieser Zusammenhalt kann allerdings leicht gelöst werden, weil die Stabilität der Trennwände 15, 16 gering ist und sich das silikonisierte Papier von den Grenzflächen der Massenstücke 11 bis 14 gut lösen läßt. Die Massenstücke 11 bis 14 haben eine länglich prismatische Form , die sich mit Axt oder Messer in kleinere Stücke quer zerteilen läßt. Auf diese Weise ist es möglich, kleinere Massenstücke zu erhalten, die man schneller aufschmelzen kann als große, zusammenhängende Blockstücke.The filled vessels are sent to the end user. Before use, the end user opens the vessels by loosening the tensioning straps 6 and tearing off the seam strip 10. The mass pieces 11 to 14 are then exposed, but are still held together by the partitions. This cohesion can, however, be easily released because the stability of the partition walls 15, 16 is low and the siliconized paper can be easily removed from the interfaces of the mass pieces 11 to 14. The mass pieces 11 to 14 have an elongated prismatic shape that can be cut into smaller pieces with an ax or knife. In this way it is possible to obtain smaller mass pieces that can be melted faster than large, coherent block pieces.

Zum Einlegen in Gefäße von 30 l Fassungsvermögen haben sich Trennwände 15, 16 bewährt, die mit Wellpappe von 1,5 bis 2 mm Wandstärke bei etwa 300 bis 500 g/m² Flächengewicht und mit silikonisiertem Papier von 90 g/m² (sogenanntes Silikonkraftpapier) hergestellt werden.Partitions 15, 16, which are made with corrugated cardboard with a wall thickness of 1.5 to 2 mm and a basis weight of about 300 to 500 g / m² and with siliconized paper of 90 g / m² (so-called silicone kraft paper), have proven effective for insertion into vessels with a capacity of 30 l will.
