Collapsible container

There is a great need for containers that are used to contain perishable goods can. Such containers must be stable in order to withstand high loads when the containers are on top of one another be stacked.

The containers are preferably made from materials which have a low specific weight.

Due to the ζ.Zt. The predominant problem of environmental pollution from waste mining is it highly desirable that magnificent containers can be reused many times because of this Way reduces the total amount of waste created by throwing away single-use bins arises.

In many cases, especially when shipping fresh fish or seafood, the containers must be sterilized before they can be used again.

Today there are many containers that can be collapsed and reused. However. Is none the known container can be used particularly well for transporting fish in particular or from the Sea-sourced food and products for several reasons. Most containers can't can be easily cleaned for reuse. Many only have poor stacking strength and are complex to manufacture.

The invention is therefore directed to a container that can be used very often before it is destroyed. It should be one

109850/1355

collapsible container act that is light and simple Can be assembled and disassembled, making it easy to return for reuse is made cheaper. In addition, this collapsible container should be economical to manufacture have high stacking strength.

These and other features emerge from the following description of exemplary embodiments on the basis of hand the enclosed drawing. The drawing shows in:

Fig. 1 is a perspective view partially disassembled taken container;

ψ Fig 9 a partial section through modified connecting elements for the container of Fig. 1.

Fig. Io shows a partial section through a further modified one Embodiment of fasteners for the container according to FIG. 1.

As can be seen from the drawing, a container Io consists of end plates 12 and 14, side walls 16 and 16, from a Deekel 2o and from a bottom 22.

Each faceplate is constructed identically, so it is sufficient to describe only one of them. the Face plate 12 has means which are detachable into other means on the side walls, the lid and the bottom of the container.

The engagement means intended for the side walls 16 and 18 comprise elongate elements 26 and 28 of FIG

- 4 -. . . .. _: 10 9 8 5 0/1355

J-shaped cross-section, as can best be seen from FIG. The long leg Jo of the element 26 is fastened to the face plate 12 in the usual manner. The element 26 can be made from almost any rigid material. However, materials that can be extruded, such as metal or plastic, are preferred. The cost of manufacturing the elements by extrusion is considerably lower than that of machining them from metal or wood.

The short leg j52 of the element 26 extends beyond the edge of the end plate 12 and is directed against the outer surface of this end plate. The other elongated element 28, intended for a side wall, is fastened to the end plate 12 via its long leg j? 4. The short leg 36 of the element 28 is oriented relative to the end plate 12 in the same way as the leg 32. Accordingly, the grooves formed by the legs of the elements 26 and 28 open towards the outer surface of the end plate 12.

On the upper edge of the face plate 12 sits an element J58 with an L-shaped cross-section, one leg of which 4o is attached to the inner surface of the face plate 12.

The other leg 42 extends substantially perpendicular to the face plate 12.A further element 4ji is arranged along the lower edge of the face plate, which also has an L-shaped cross section and with one leg. 44 attached to the inner surface of the faceplate, while the other is Socket 45 extends substantially perpendicular to it.

The end plate 14 is provided with identical connecting elements that have the same reference numerals wear with the addition of a line.

The side wall 16 carries a hook-shaped section 46 or 46 ¹ at each of its front ends. These can be designed as one-piece parts according to the drawing. However, it is also possible to manufacture them as separate elements from a different material and then to attach them to the side wall 16.

The side wall 18 is also hook-shaped

Sections 48 and 48 'provided.

The container * is very easy to assemble. The side walls Io and 18 are set upright, with the end plates 12 and 24 transversely between extend them and are disposed inwardly from the end faces of the side walls. The end walls J2 and 14

109850/1355

are then moved against the ends of the side walls 15 and 18, whereby the elements 26, 26 ^! and 28, 28 'to engage the hook-shaped portions 46, 46' and 48, 4G ^f . This can be seen from FIGS. 4 and 3.

In order to keep the side walls and the end plates in an upright position, it is only necessary to insert the base 22. This results in the container remaining erect without the need for additional fasteners. After the container has been filled , aev cover "is pushed in, after which the container can be transported.

The Deekel 2o and the bottom 22 each have cutouts Areas 47 and 47 * or 49 and 49 '. this results in the outer surfaces of the container being smooth after assembly.

If desired, fasteners such as tapes, Latch or dsl., Can be used to hold the lid 2o in to be held firmly in position.

can fall apart freely. In disassembled Condition, each element can be cleaned and sterilized very carefully as required. None are formed Corners where dirt and debris could collect.

The container can therefore be assembled and disassembled easily and quickly. He lets himself be careful clean so that it can be re-used many times can turn.

In addition, due to the unique construction, the stacking and handling occurring loads are limited to the end regions of the container, so that the lid and the side walls of stresses be kept free.

In the embodiment according to FIG. 7, the side walls consist of a plurality of slats 5 ° to 5 ^ · The connecting elements in this embodiment correspond to those of the container described above, with additional recesses 58 in the elongated elements 26, 28 and ribs 60 on the inner walls dex · hook-shaped sections 46 and 48 of each slat are provided. In this way, the slats can be held at a distance from one another by the ribs 60 sliding into the recesses 58.

This type of container is particularly suitable for products that require a certain amount of air circulation is desirable.

A further modification of the invention with regard to the connecting elements is shown in FIGS. 9 and Io emerged. In this embodiment, each connecting element a fixed strut 61 with a longitudinal groove 62 in which a tongue 64 of the associated Wall element fits into it. The struts 61 are attached to the end plates 12 and 14, respectively point their surfaces bearing the groove against the associated wall element. In this embodiment, sets the container together by placing the end plates 12 and 14 upright and inserting the wall elements.

This construction is similar to that of known containers, but differs in particular with regard to the Strength properties. The one consisting of tongue and groove Connection runs essentially along the center line of the struts 61, so that flat load-transmitting Areas 6o and 68 are formed to increase the strength of the container.

109850/1355

The invention thus creates a collapsible container of high stacking strength, at the ends of which means are provided, which cooperate with other means on the side walls, the ceiling and the bottom, urn the To hold containers together in the assembled state without the need for additional fasteners would be.
