Description

Die Erfindung betrifft einen Behälter aus mehreren Faserschichten, insbesondere aus mehreren Schichten von Kraftpapier, bestehend aus einer Wand, deren Schichten unter Verwendung eines Klebstoffes miteinander verbunden sind, sowie aus einer Bodenscheibe, aus gleichem Material, wobei die Verbindung zwischen der Bodenscheibe und der Behälterwand aus Zungen besteht, welche umgefaltet und mit der Bodenscheibe verklebt worden sind, welcher Behälter einen Stülpdeckel haben kann, dessen Verbindung zwischen Deckelkörper und Deckelscheibe in entsprechender Weise ausgebildet ist.The invention relates to a container made from several layers of fibers, in particular from several layers of kraft paper, consisting of a wall, the layers of which are connected to one another using an adhesive, and a base plate made of the same material, the connection between the base plate and the container wall There are tongues, which have been folded over and glued to the base plate, which container can have a slip lid, the connection between the cover body and the cover plate is formed in a corresponding manner.

Ein derartiger Behälter ist bekannt aus der schweizerischen Patentschrift Nr. 406825. Bei diesem bekannten Behälter werden die Zungen durch V-förmige Ausschnitte aus der Randzone der Behälterwand gebildet, wobei die Zungen der jeweiligen miteinander zu verklebenden Schichten derart zueinander versetzt worden sind, dass eine gleichmässige Verteilung der Zungen im Verbindungsbereich mit dem Boden erhalten wird. Dieser Behälter hat sich in der Praxis nicht bewährt, weil die Verbindung den auftretenden Belastungen wegen der Bruchwirkung im Knickbereich nicht gewachsen war, und weil sich die Zungen lösten.Such a container is known from Swiss Patent No. 406825. In this known container, the tongues are formed by V-shaped cutouts from the edge zone of the container wall, the tongues of the respective layers to be glued to one another being offset such that a uniform Distribution of the tongues in the connection area with the floor is obtained. This container has not proven itself in practice because the connection was unable to cope with the stresses occurring due to the breaking effect in the kink area and because the tongues loosened.

In der Praxis bewährt hat sich eine Parallel-Entwicklung derartiger, aus Faserschichten bestehender Behälter, wobei die Verbindung zwischen der Behälterwand und dem Boden bzw. dem Dekkelrand und Deckelplatte von einem Metallring gebildet wird, der die beiden zu verbindenden Teile einklemmt. Ein Beispiel davon ist in der britischen Patentschrift Nr. 621262 zu finden. Diese Verbindung mit Metallringen ist zuverlässig, erhöht jedoch den Preis.A parallel development of such containers consisting of fiber layers has proven itself in practice, the connection between the container wall and the bottom or the lid edge and cover plate being formed by a metal ring which clamps the two parts to be connected. An example of this can be found in British Patent No. 621262. This connection with metal rings is reliable, but increases the price.

Zweck der Erfindung ist, einen Behälter einfacher und zuverlässiger Konstruktion zu schaffen, ohne die Notwendigkeit einen Metallring zu verwenden.The purpose of the invention is to provide a container of simple and reliable construction without the need to use a metal ring.

Dieser Zweck wird erfindungsgemäss dadurch erreicht, dass die Schichten von Wand, Bodenscheibe und gegebenenfalls von Deckelkörper und Deckelscheibe mit einem heiss schmelzbaren Klebstoffverleimtworden sind, dass die Einschnitte in den Rand der Behälterwand bzw. des Deckelkörperrandes zur Bildung der Zungen bestehen aus parallel zur Achse der Behälterwand bzw. des Deckelteiles verlaufenden geraden Einschnitten, deren Einschnittflächen einen scharfen Winkel (a) mit der jeweiligen tangierenden Fläche der Wand bzw. des Deckelkörpers bilden, und dass die Zungen der Wand mit der Bodenscheibe bzw. die Zungen des Deckelkörpers mit der Deckelscheibe verleimt worden sind unter Verwendung eines vor dem vollständigen Umfalten der Zungen heiss aufgetragenen Klebstoffes, der vorzugsweise selbst auch heiss schmelzbar ist.This purpose is achieved according to the invention in that the layers of the wall, base plate and optionally the cover body and cover plate have been glued with a hot-meltable adhesive, that the incisions in the edge of the container wall or the cover body edge to form the tongues consist of parallel to the axis of the container wall or the straight part of the cover part, the cut surfaces of which form a sharp angle (a) with the respective tangent surface of the wall or the cover body, and that the tongues of the wall have been glued to the base plate or the tongues of the cover body have been glued to the cover plate using an adhesive applied hot before the tongues are completely folded over, which is preferably itself hot-meltable.

Der Klebstoff hat den bisher nicht erkannten Effekt, dass der heiss aufgetragene Klebstoff zum Verkleben der Zungen mit der Bodenscheibe die Knickstelle des Rumpflaminates derart erwärmt, dass der zwischen den Schichten des Rumpflaminates vorhandene heiss schmelzbare Klebstoff erweicht und dadurch das Faserschichtengebilde nachgiebig wird. Der heiss aufgetragene Klebstoff bewirkt dadurch eine zeitliche Beweglichkeit der Faserschichten im Bezug aufeinander, wodurch ein spannungsfreies Umfalten der Zungen erreicht wird. An der Knickstelle oder Umfaltstelle treten dadurch keine Brücken mehr auf und die Zungen haben nicht länger die Neigung zum Zurückfedern, wie dies wohl bei den früher verwendeten Klebstoffen der Fall war. Mit der Erfindung wird dadurch einen Behälter erhalten, der einfach in der Konstruktion ist und zuverlässig im Gebrauch.The adhesive has the previously unknown effect that the hotly applied adhesive for gluing the tongues to the base plate warms the kink of the fuselage laminate in such a way that the hot-meltable adhesive present between the layers of the fuselage laminate softens and, as a result, the fiber layer structure becomes flexible. The hot applied adhesive causes the layers of fiber to move with respect to one another, which means that the tongues can be folded over without tension. As a result, there are no longer any bridges at the kink or fold point and the tongues no longer have a tendency to spring back, as was probably the case with the adhesives previously used. With the invention, a container is obtained which is simple in construction and reliable in use.

Es sei in diesem Zusammenhang bemerkt, dass man bei der Herstellung von Behälterteilen wie Wand, Deckel und Boden sowie diese für diejenige Behälter verwendet, bei denen die Verbindung mittels des genannten Metallringes zustande gebracht wird, schon seit einiger Zeit den heiss schmelzbaren Klebstoff verwendet, um die Faserschichten miteinander zu verbinden. Dabei tritt jedoch das Problem des Umfaltens von Zungen und deren Verklebung mit einer Bodenscheibe nicht auf.It should be noted in this context that the hot-meltable adhesive has been used for some time in the manufacture of container parts such as walls, lids and bases, as well as for those containers in which the connection is brought about by means of the metal ring mentioned to connect the fiber layers together. However, the problem of folding tongues and gluing them to a base plate does not arise.

Zur Erhaltung der zuverlässigen Konstruktion gehört jedoch erfindungsgemäss ebenfalls, dass die Zungen erhalten worden sind, indem in den Rand der Behälterwand bzw. Deckelkörperrandes parallel zur Achse des Behälters gerade Einschnitte durchgeführt worden sind, deren Einschnittsflächen einen scharfen Winkel mit der jeweiligen tangierenden Fläche der Wand bzw. Deckelkörpers bilden. Man erreicht dadurch, dass beim Umfalten der Zungen diese in überlappender Weise übereinanderschieben, wobei der aufgetragene Klebstoff gleichmässig verteilt wird. Je schärfer der Winkel, um so gleichmässiger schieben sich die Zungen übereinander und schmiegen sich aufeinander. Dadurch wird in spannungsfreier Weise eine Art Flansch gebildet. Diese geraden Einschnitte sind wesentlich einfacher herzustellen als die bekannten dreieckigen Ausschnitte. Sie haben ausserdem den Vorteil, dass keine Ausschnitteilchen anfallen, die entfernt werden müssten. Durch diese Form der Zungen und durch das spannungsfreie Umfalten ist eine Verbindung zwischen Behälterwand und Bodenscheibe bzw. Deckelkörper und Dekkelscheibe erreicht worden, deren Festigkeit wesentlich grösser ist als bei der bekannten Verbindung mit Zungen, und dadurch ist die Herstellung ermöglicht von Behältern, welche bezüglich der Zuverlässigkeit und der Festigkeit vergleichbar mit Metallringbehältern sind, wobei die erfindungsgemässen Behälter in der Herstellung jedoch kostengünstiger sind.To maintain the reliable construction, however, according to the invention it is also necessary that the tongues have been obtained by making straight incisions in the edge of the container wall or lid body edge parallel to the axis of the container, the incision surfaces of which are at a sharp angle with the respective tangent surface of the wall or Form lid body. The result of this is that when the tongues are folded over, they slide in an overlapping manner, the applied adhesive being distributed evenly. The sharper the angle, the more evenly the tongues slide over one another and nestle against one another. This creates a kind of flange in a stress-free manner. These straight cuts are much easier to make than the known triangular cuts. They also have the advantage that there are no cut-out particles that need to be removed. This shape of the tongues and the tension-free folding have achieved a connection between the container wall and the base plate or cover body and cover plate, the strength of which is considerably greater than in the known connection with tongues, and this makes it possible to produce containers which are suitable for Reliability and strength are comparable to metal ring containers, but the containers according to the invention are less expensive to manufacture.

Die Erfindung betrifft ebenfalls ein Verfahren zur Herstellung eines Behälters bzw. eines Deckels gemäss der Erfindung und dieses Verfahren ist dadurch gekennzeichnet, dass der heiss schmelzbare Klebstoff zumindest im Bereich der Faltlinie der Zungen auf die Innenseite der Zungen heiss aufgetragen wird und diese Zungen erst dann in die Ebene der Bodenscheibe bzw. Deckelscheibe umgefaltet werden, wenn der heisse Klebstoff das Material der Wand bzw. des Deckelkörpers erhitzt hat. Dadurch, dass der Klebstoff für die Verklebung direkt an der Faltlinie aufgetragen wird, wird gerade an der kritischen Knickstelle die Erhitzung und damit Erweichung des Klebstoffes zwischen den Faserschichten erreicht.The invention also relates to a method for producing a container or a lid according to the invention and this method is characterized in that the hot-meltable adhesive is applied hot to the inside of the tongues at least in the region of the fold line of the tongues and these tongues are then only the level of the base plate or cover plate can be folded over when the hot glue contains the mate rial has heated the wall or the lid body. Because the adhesive for the adhesive is applied directly to the fold line, the heating and thus softening of the adhesive between the fiber layers is achieved precisely at the critical kink.

Die Erfindung wird jetzt anhand der Zeichnungen näher erläutert werden.

  • Fig. 1 zeigt teilweise in Seitenansicht, teilweise im Schnitt das Grundprinzip des Behältertypes nach der Anmeldung.
  • Fig. 2 zeigt die besondere Einschnittform der Verbindungszungen.
  • Fig. 3 zeigt im Querschnitt das Prinzip der Leim-Applikation, wobei die Raupe in der Stelle 9 den Scharniereffekt auslöst.
The invention will now be explained in more detail with reference to the drawings.
  • Fig. 1 shows partly in side view, partly in section, the basic principle of the container type after registration.
  • Fig. 2 shows the special incision shape of the connecting tongues.
  • 3 shows in cross section the principle of glue application, the caterpillar triggering the hinge effect at point 9.

Der in Fig. 1 gezeigte Behälter besteht aus einem zylindrischen Körper 1, dessen Wandung aus mehreren aufeinander gewickelten Schichten aus Kraftpapier, zwischen denen sich ein Klebstoff befindet, der heiss aufgetragen wird und bei erneuter Erhitzung geschmolzen werden kann, hergestellt ist.The container shown in Fig. 1 consists of a cylindrical body 1, the wall of which is made up of several layers of kraft paper wound between one another, between which there is an adhesive which is applied hot and which can be melted when heated again.

Dieser Behälter hat einen Boden 2, der mit der Behälterwand 1 dadurch verbunden ist, dass die untere Kante der Behälterwand 1 bei 3 nach innen umgefalten worden ist. Um dieses Umfalten zu ermöglichen, ist es bekannt, V-förmige Einschnitte vorzusehen. Erfindungsgemäss werden jedoch gerade Einschnitte vorgesehen, wie noch näher erläutert werden wird.This container has a bottom 2 which is connected to the container wall 1 in that the lower edge of the container wall 1 has been folded inwards at 3. In order to make this folding possible, it is known to provide V-shaped incisions. According to the invention, however, incisions are being made, as will be explained in more detail below.

Der Behälter hat einen Stülpdeckel 4, dessen Verbindung von Deckelkörper 5 und Deckelscheibe 7 in gleicher Weise, wie beim Rumpfteil gesagt, verklebt ist. Die Verbindung 3 und 6 ist flüssigkeitsdicht.The container has a slip lid 4, the connection of the lid body 5 and the cover plate 7 is glued in the same way as said for the fuselage part. The connection 3 and 6 is liquid-tight.

Die Prinzipskizze, Fig. 1, gilt sowohl für die Erfindung wie auch im wesentlichen für den Stand der Technik gemäss der schweizerischen Patentschrift Nr. 406825.The schematic diagram, FIG. 1, applies both to the invention and essentially to the state of the art according to Swiss Patent No. 406825.

Fig. 2 zeigt eine Behälterwand 1, die an einem Ende mit Zungen 13 versehen worden ist, welche durch axiale Einschnitte 14, die jeweils einen scharfen Winkel mit der tangierenden Ebene 16 bilden, entstanden sind.Fig. 2 shows a container wall 1, which has been provided at one end with tongues 13, which are created by axial incisions 14, each of which forms a sharp angle with the tangent plane 16.

Dadurch erreicht man, dass beim Umfalten der Zungen diese sich übereinander schieben werden, ohne dass man dazu besondere Massnahmen zu treffen braucht, weil die schrägen, von den Schnittflächen gebildeten Trennungsfugen übereinandergleiten.This means that when the tongues are folded over, they will slide over one another without having to take any special measures because the oblique separation joints formed by the cut surfaces slide over one another.

Fig. 3 zeigt nun den erfindungsgemässen Fertigungsschritt für die Verbindung zwischen dem Boden 2 und der Behälterwand 1.3 now shows the manufacturing step according to the invention for the connection between the bottom 2 and the container wall 1.

An der Stelle 9, auf der Innenseite der Zungen 13, und gegebenenfalls auch an den Stellen 10, werden Raupen aus einem Klebstoff heiss aufgetragen und anschliessend werden die Zungen 13 entsprechend der Linie 11 flach auf den Boden 2 umgefaltet und so lange angepresst gehalten, bis der Klebstoff aufgebunden ist.At the point 9, on the inside of the tongues 13, and possibly also at the points 10, beads are applied hot from an adhesive and then the tongues 13 are folded flat on the floor 2 according to the line 11 and held down until the adhesive is bound.

Der heiss aufgebrachte Klebstoff sorgt nun insbesondere an der Stelle 8 dafür, dass die ebenfalls mittels eines derartigen Klebstoffes verleimten Schichten der Gebindewand erhitzt werden und dadurch freier beweglich in bezug aufeinander werden, wodurch das Umfalten leicht stattfinden kann und nach dem Umfalten eine spannungsfreie Verbindung erhalten worden ist.The hot-applied adhesive now ensures in particular at point 8 that the layers of the container wall which are also glued by means of such an adhesive are heated and thereby become more freely movable with respect to one another, as a result of which folding can take place easily and a tension-free connection has been obtained after folding is.

Beim Übereinandergleiten der Zungen wird der Klebstoff gleichmässig verteilt. In Fig. 2 sind zwei Zungen 13' schon etwas vorgebogen, um das Übereinandergleiten zu zeigen. Je schärfer der Winkel a um so besser findet das Übereinandergleiten statt.When the tongues slide over each other, the adhesive is evenly distributed. In Fig. 2, two tongues 13 'are already slightly bent to show the sliding over each other. The sharper the angle a, the better the gliding takes place.
