concerning:

"Fold out delivery box, for example for fish"

The innovation relates to a fold-out delivery box, existing from a bottom, two side walls and two end walls.

There are known delivery containers for numerous articles, which are made of cardboard or foam plastic and as disposable packaging to serve. One has the disadvantage that such containers are neutral, since they can only be used once while receiving the Faced with problem is how to get rid of these pollution-free containers.

Furthermore, containers, for example wooden boxes or containers made of a rigid plastic, are known which are sufficiently stable are that they can be used several times. However, these have the disadvantage that the empty containers take up space, namely through storage by the user and during the subsequent return transport to the sender of the article. The return shipment is expensive in that space is required in expensive means of transport and this Shipping itself does not generate any income. The sender also needs a lot of space to store the empty containers until the time of the Filling.

The task of the innovation is therefore to create a stable container that can be used several times, but when it is returned takes up as little space as possible. The idea is to make the containers fold-out so that they can be unfolded after they have been emptied and transported back to the sender in this unfolded state can. However, the fact that it can be folded out must not endanger the stability of the container while it is being raised to a walking position and unfolding should take place quickly and easily, preferably without the use of tools.

This is achieved according to the innovation in that the box is made of a rigid plastic and the side and End walls by means of hinge parts formed integrally with them with hinge parts formed integrally with the base are connected, and that the walls in the working position by means of snap members also formed integrally with them are lockable.

The erection of the box to the operational position requires only the folding up of the walls of the 3oden, after which the snap organs be locked. Unfolding is also easy, because after the snap elements have been released, the walls automatically extend into fold down the boclen level.

Preferably at least a part of the snap members at the ends are also articulated with the upper edges of the sides or End walls of connected strips provided, which come to lie parallel to the ground in the working position.

As a result, on the one hand, only a few snap devices are required for locking in the working position and, on the other hand, one increases Support surface, by means of which a number of the boxes according to the invention can be stacked on top of one another in the working position, one more stable Stack can be formed.

In a certain embodiment, the snap members could consist of web-like projections formed on the inside of the walls

exist, against which the edges of adjacent walls can be fixed are.

In another embodiment, the snap members could, if the box is provided with the abovementioned connecting strips consists of pin-like projections provided on the inside of these strips or otherwise on the walls, which can be brought into engagement with openings provided at appropriate locations in the walls.

For shipping fish and other foodstuffs, the fold-out forms Delivery box according to the innovation, on the one hand through the use of plastic and on the other hand because it can be folded out, an easy-to-clean shipping container, so that the quality of the shipped goods is better guaranteed is.

The innovation is explained in more detail below using the drawing, which represents an embodiment of the delivery box according to the innovation.

Figure 1 shows the delivery box in perspective and in the unfolded position, and Figure 2 shows the delivery box in perspective in the Work situation.

The box shown has the following parts: a bottom 1, two side walls 2, 3 and two end walls 4, 5. Between a corresponding edge of each side and end wall and the floor a hinge is provided. In the embodiment shown, the hinges 6 each consist of a continuous strip the same plastic material from which the walls are made are which strip in its entire length with a corresponding edge of the relevant side walls and bottom connected is. Such hinges can be done in the manufacture of the container, for example by means of injection molding in a mold could be provided in that at the point of the hinge a material thickness is provided which is sufficient large enough for a strong enough connection, but small enough

to allow sufficient flexibility so that the wall so hinged from the horizontal to the vertical position according to Figure 2 is pivotable.

However, the hinges could also be loop-shaped parts on the wall or the floor and pin-like parts on the other hand on the floor or wall. After shaping the bottom and the walls of the box, with the molded hinge parts, these hinge parts are brought into engagement with one another and remain in place this position during the entire further use of the delivery box, both in the unfolded and in the working position.

In the embodiment shown are at the top of a each side wall, likewise by means of similar hinge parts, fastened connecting strips 7, the width of which can be dimensioned can that they cover the entire upper opening of the box together, but also smaller, as in the embodiment shown. The function of these strips is to form a support surface for another box to be stacked on top of the box. Simultaneously are at the ends of the connecting strips 7, on the inside thereof, pin-like projections 8 provided, molded in one piece with the strip concerned. When erecting the box to In the working position according to FIG. 2, these pins 8 are inserted into associated recesses or holes 9 in the upper edge of the two end walls 4, 5 pressed in so that the box is locked in the working position.

The locking is also possible in another way, which is an alternative Locking is also shown in Figure 1. There are web-like projections Io on the inner walls of the side walls 2, 3 molded onto the box, each time two projections at each end of a side wall. When erecting the box will be first the end walls 4, 5 folded up and then the side walls, with each pair of projections Io clamping around the opposite one Edge of an end wall 4, 5 grips "

t «

It is clear that such ridges or pin-shaped projections with recesses also provided in other places on the walls can be.

Certain items, for example fish, can easily be packed in the box along with pieces of ice. The Water from the ice can leak through the box through a number of leakage openings provided near the lower edges of the walls 11 leave. It is also possible to first put the articles in a loose inner bag, for example made of transparent plastic, to pack and then arrange these bags in the boxes. As an example of the dimensions of such a box can Mentioned are: an external dimension of length, width and height of 600 χ 400 χ 19o mm, intended for a weight content of IS kg. Of course, other dimensions are also possible, for example for weights of Io or 25 kg.
