Abstract

The container has self locking tongues and/or grooves wedge shaped esp. with a half draw angle of 3 degrees. The material is esp. foamed polystyrene. The inner surfaces have cushioning protrusions and the outer surfaces raised sections between which adhesive tape is applied to hold the box together the close it. Construction is space saving for storage and transport.

Description

  

  
 



  Behälter
Es sind Behälter aus Schaumstoff bekannt geworden, welche den Vorteil aufweisen, dass sie ausserordentlich leicht sind und infolge ihrer Materialeigenschaften, insbesondere bei Verwendung von Schaumstoffen, das Packgut hervorragend schützen. Derartige Behälter sind jedoch bisher nur für Kleingut bekannt geworden, wobei einer der Gründe darin liegen dürfte, dass derartige Packbehälter nicht nur fabrikatorisch hohe Anforderungen stellen, sondern auch sperrig sind. Die vorliegende Erfindung umgeht diese Nachteile, indem der erfindungsgemässe Behälter aus Schaumstoff besteht, zerlegbar ist und die Wände des Behälters zum Zusammenstecken mit Nuten und Federn versehen sind.



   Ein Ausführungsbeispiel des Erfindungsgegenstandes wird anschliessend anhand von Figuren erläutert. Es zeigen:
Fig. 1 einen Ausschnitt aus einem zerlegbaren Behälter, mit abgehobenem Deckel, in Draufsicht,
Fig. 2 einen Schnitt gemäss Linie I-I der Fig. 1,
Fig. 3 einen Schnitt gemäss Linie II-II der Fig. 1,
Fig. 4 eine Aufsicht auf die Innenseite des Deckels des Behälters gemäss der Fig. 1,    Fig.S    die Ansicht einer Seitenwand des Behälters, mit Stegen zum Anlegen von Klebband.



   Der in den Fig. 1 - 5 dargestellte, zerlegbare Behälter besteht aus Schaumstoff, vorzugsweise Polystyrol.



  In den Figuren sind die Seitenwände 1 und 3 ersichtlich sowie der Deckel 5 des Behälters. Die Seitenwand 3 ist, wie in Fig. 1 dargestellt, mit Nuten versehen, von welchen nur die Nut 7 ersichtlich ist. Diese weist einen keilförmigen Anzug von vorzugsweise 30 auf, derart, dass eine Feder 9 der Seitenwand 1 beim Einpressen in die Nut 7 diese dehnen muss, wobei die elastischen Eigenschaften das Festklemmen der Feder 9 in der Nut 7 sicherstellen. Der Winkel von 30 ergibt selbsthemmende Keilflächen, so dass die Verbindung der Seitenwände untereinander und mit dem Boden sowie dem Deckel 5 nicht nur festigkeitsmässig eine äusserst stabile Konstruktion darstellt, sondern ein Auseinanderfallen verhindert.

  In Fig. 4 sind, neben einer Deckelnut 11 auch Reihen von Polsterzapfen 13 ersichtlich, welche aufgrund ihrer Elastizität das zu schützende Gut in optimaler Weise festhalten und welche es ermöglichen, dass selbst bei grober Handhabung des Behälters dessen Packgut nicht beschädigt wird.



   Zwecks zusätzlicher Sicherungsmöglichkeit sind die Wände des Behälters mit Stegen 15 versehen, über welche zum Verschliessen und Halten des Behälters Klebbänder 17 gelegt werden. Zur Materialsparung sind beidseits der Stege 15 Ausnehmungen 19 in den entsprechenden Wänden des Behälters angeordnet.



   Der beschriebene Behälter erlaubt nach dessen Gebrauch ein Zerlegen in Platten, welche einen Transport als gewöhnliches Gut und nicht als Sperrgut gestatten und zudem wenig Stapelraum beanspruchen, im Gegensatz zu den bisher bekannten Behältern dieser Art. Auch gestattet das Material aufgrund seiner elastischen Eigenschaft ohne zusätzliche Mittel eine gegenseitige Halterung der Behälterwände, wobei zwecks weiterer Sicherung, insbesondere für den Bahntransport diese Behälter mit Klebbändern umwunden werden.

  container
Containers made of foam have become known which have the advantage that they are extremely light and, due to their material properties, especially when using foams, provide excellent protection for the packaged goods. However, such containers have hitherto only become known for small items, one of the reasons probably being that such packing containers not only have high manufacturing requirements, but are also bulky. The present invention avoids these disadvantages in that the container according to the invention is made of foam, can be dismantled and the walls of the container are provided with grooves and tongues for plugging together.



   An exemplary embodiment of the subject matter of the invention will then be explained with reference to figures. Show it:
1 shows a detail from a collapsible container, with the lid lifted off, in plan view,
FIG. 2 shows a section along line I-I of FIG. 1,
3 shows a section along line II-II of FIG. 1,
4 shows a plan view of the inside of the lid of the container according to FIG. 1, FIG. 5 shows a view of a side wall of the container, with webs for applying adhesive tape.



   The collapsible container shown in FIGS. 1-5 is made of foam, preferably polystyrene.



  In the figures, the side walls 1 and 3 can be seen as well as the lid 5 of the container. The side wall 3 is, as shown in Fig. 1, provided with grooves, of which only the groove 7 can be seen. This has a wedge-shaped tightening of preferably 30, such that a tongue 9 of the side wall 1 has to stretch it when it is pressed into the groove 7, the elastic properties ensuring that the tongue 9 is clamped in the groove 7. The angle of 30 results in self-locking wedge surfaces, so that the connection of the side walls to one another and to the base as well as the cover 5 is not only an extremely stable construction in terms of strength, but also prevents them from falling apart.

  In Fig. 4, in addition to a lid groove 11, rows of cushion pins 13 can be seen which, due to their elasticity, hold the goods to be protected in an optimal manner and which enable the packaged goods not to be damaged even if the container is roughly handled.



   For the purpose of additional security, the walls of the container are provided with webs 15, over which adhesive tapes 17 are placed to close and hold the container. To save material, recesses 19 are arranged in the corresponding walls of the container on both sides of the webs 15.



   The container described allows it to be dismantled into plates after use, which allow transport as ordinary goods and not bulky goods and also require little stacking space, in contrast to the previously known containers of this type. The material also allows due to its elastic property without additional means a mutual support of the container walls, whereby these containers are wrapped with adhesive tape for the purpose of further security, in particular for rail transport.
