Description

The invention relates to a prismatic packaged goods container with two headboards forming the end walls, made of wood or fibreboard and edge strips, and an attached to the headboards, optionally two-part container jacket made of corrugated cardboard or the like.

• Durch das Eintreiben der Verbindungselemente, also z. B. der Drahtklammern, Breitkopfnägel od.dgl., wird die Wellpappenaußendecke des Behältermantels beschädigt, was einerseits die Verbindung im Bereich der Befestigungselemente schwächt, anderseits ein Eindringen von Feuchtigkeit in die dann offenen Wellen und in weiterer Folge eine Verringerung der Belastbarkeit des Behälters mit sich bringt. Dazu kommt noch, daß die Verbindungselemente bei Vollholzplatten parallel zur Holzfaser bzw. bei Sperrholzplatten längs der einzelnen Holzlagen eindringen, so daß ihre Haltbarkeit von vornherein reduziert ist, ganz abgesehen davon, daß die ganze Wellpappe wegen der punktförmigen Belastung im Bereich der Verbindungselemente ausreißen kann. Außerdem sind die Stirnseiten des Behältermantels ungeschützt, es kann dort also ebenfalls Feuchtigkeit eindringen, was in Verbindung mit den unvermeidlichen Transportbeanspruchungen zu einer Spaltung der Wellpappe in einzelne Papierlagen und damit zu einer weiteren Behälterbeschädigung bzw. ~schwächung führen kann. Werden zur Verbindung des Behaltermantels mit den Rändern der Kopfteile Drahtklammern verwendet, von denen jeweils ein Schenkel in die Platte des Kopfteils und der andere Schenkel in die betreffende Randleiste eingetrieben wird, so muß die Dicke der Randleisten der Stegbreite der Klammern angepaßt werden, und es ist nicht möglich, entsprechend der gegebenenfalls zu erwartenden geringeren Belastung dünnere Randleisten zu verwenden, was den Materialbedarf und das Gewicht unnötig erhöht.

In packaged goods containers of this type known from practice, the edge strips are fastened directly to the outside of the plates of the head parts made of solid wood, plywood or wood fiber pressed material, the edge surfaces of the plates and the side surfaces of the edge strips being aligned. The corrugated cardboard or the like. The container casing formed lies against these aligned surfaces, the casing end faces being arranged in one plane with the outer surfaces of the edge strips, so that these end faces of the container casing remain unprotected by the edge strips. The container jacket made of corrugated cardboard or the like. is connected to the headboards by nails or wire clips. This construction now has several serious disadvantages:

• By driving in the connecting elements, e.g. B. the wire clips, wide-headed nails or the like, the corrugated cardboard outer ceiling of the container shell is damaged, which on the one hand weakens the connection in the area of the fastening elements, on the other hand, a penetration of moisture into the then open shafts and subsequently a reduction in the load-bearing capacity of the container. In addition, the connecting elements penetrate parallel to the wood fiber in solid wood panels or plywood panels along the individual layers of wood, so that their durability is reduced from the outset, quite apart from the fact that the entire corrugated cardboard can tear out due to the point load in the area of the connecting elements. In addition, the end faces of the container shell are unprotected, so moisture can also penetrate there, which in connection with the inevitable transport stresses can lead to a splitting of the corrugated cardboard into individual layers of paper and thus to further damage or weakening of the container. If wire clips are used to connect the container jacket to the edges of the head parts, one leg of which is driven into the plate of the head part and the other leg is driven into the relevant edge strip, the thickness of the edge strips must be adapted to the web width of the clips, and it is not possible to use thinner edge strips in accordance with the possibly expected lower load, which unnecessarily increases the material requirements and the weight.

Another not insignificant disadvantage can also be seen in the fact that the containers, when shipped empty, have a large costume volume and accordingly cause high freight costs. On the other hand, it would be desirable to have a packaged goods container that has sufficient strength and resilience, but can be assembled from a few flat parts by the user himself, without having to use special tools or connecting means, so that he uses only a small volume of freight as empties.

The invention is therefore based on the object, all to provide mentioned deficiencies and to eliminate a Packgutbehälter of the type described, which has a ER _h öhte strength with a reduced risk of damage and can be easily assembled from flat items.

The invention solves the problem in that the edge strips are held by at least two spacer plates at a distance corresponding to the thickness of the corrugated cardboard from the wood or wood fiber boards and the container jacket has angled edge tabs that are left in the spaces left by the spacer plates between the edge strips and the wood or wood fiber boards of the head parts can be inserted, with the spaces in the direction of the edge strips being longer than the edge flaps in at least one lateral surface and the latter being able to be extended to the full length of the space by means of locking strips which can be inserted into the spaces.

So since the edge tabs of the container casing are only inserted into the free spaces between the edge strips and the wood or wood fiber boards of the head parts, the container can be easily assembled or transported in a disassembled state without special tools, whereby it only consists of flat parts, namely consists of the two head parts and the initially also flat and only bent during the assembly tank shell. Since the edge flaps have to perform a pivoting movement during assembly, their length must not correspond fully to the length of the spaces in the direction of the edge strips, because otherwise the edges of the spacer plates would prevent the edge flap edges from swiveling in. Therefore, the difference in length between the edge tab on the one hand and the gaps on the other hand is provided according to the invention, which enables the free pivoting of the edge tab during assembly. Through the inserted bar strips but then the spaces delimited by the spacer plates are appropriately filled, so that the pivoting movement of the edge tabs is prevented and the container is held firmly together without additional fastening means being required. If, however, the locking strips are pulled out of the gaps, the container can be disassembled without being destroyed. Of course, the absence of nails, staples or other connecting means reduces the packaging weight and makes assembly easier, while the outer cover of the corrugated cardboard remains undamaged. There is also no weakening in the area of the connection points between the corrugated cardboard forming the container jacket and the head. Neither are solid wood panels parallel to the fiber or plywood panels along the wood layers penetrating and therefore their durability is reduced. The thickness of the edge strips can be fully adapted to the expected loads, and there is no need for over-dimensioning. Finally, the sensitive open corrugated cardboard face is moved away from the endangered container edges, so that the risk of damage which otherwise arises there is also eliminated. Finally, the marginal ridges are offset up to the outer surface of the container casing and thus provide real edge protection. The container jacket does not have to be made in one piece with all four jacket walls; it can also consist of a main part which results in three connected walls and an insertable supplementary part.

In the drawing, the subject matter of the invention is shown in one embodiment, namely show

• 1 shows the container jacket with a head part before assembly in the diagram,
• 2 is a vertical section through part of the finished container along the line II-II of FIG. 1st
• Fig. 3 shows a corresponding horizontal section along the line III-III of Fig. 1 and
• Fig. 4 shows a head part and the container jacket during assembly.

The packaged goods container according to the invention consists of two head parts 1 forming the end walls, only one of which is shown, and a correspondingly folded container casing 2. The two head parts 1 are made from a wood or fibreboard 3 and edge strips 4, the edge strips 4 with the help are held by spacer plates 5 at a distance from the plate 3 which corresponds to the thickness of the corrugated cardboard or the like from which the container jacket 2 is made. The container jacket 2 has angled edge tabs 6, 6a. The length of the edge tabs 6 of the lower lateral surface corresponds to the spaces left by the spacer plates 5. In contrast, the spaces in the vertical lateral surfaces 2a are longer in the direction of the edge strips 4 than the edge tabs 6a. These shorter edge tabs 6a are then supplemented by insertable locking strips 7, 7a to the full length of the intermediate space, the locking strips 7 extending to both sides (FIG. 1), whereas, according to FIG. 4, shorter locking strips 7a are provided, the length of which corresponds to the width of the edge tabs 6a corresponds.

The container jacket 2 does not need to form all four walls, it could also consist of only three walls and can be supplemented by an attachable wall part, especially since the fully filled packaging containers are anyway enclosed in the usual manner with tensioning straps.
