DESCRIPTION:
BRIEF SUMMARY
The invention relates to a container, as described in the introductory clause of claim 1.
Such containers are preferably constructed so as to be able to be dismantled or able to be folded into themselves, so as to take up a small transportation volume whilst being transported in empty state.
In a known container--according to EP-A-0 211 795--the side walls and end walls have a plurality of cooperating tongues and slits, with which these are attached to each other in circumferential direction of the container and which position the lateral and end walls in position with respect to each other, in which they may be connected with the base. A disadvantage in this construction is that in dismantled state the walls and the base are separate from each other as individual parts and therefore, before being used, the parts have to be sorted and, moreover, the risk exists that individual parts are lost.
In addition a container--according to EP-A-0 443 327--is known, which is able to be folded together into itself and in which four side walls are mounted so as to be orientable on the base and which in the folded in state brings about a multi-layered arrangement of the base and of the side walls. In this embodiment, it is disadvantageous that the articulation arrangements between the side walls and the base, depending on which position the side wall forms in folded in state with respect to the base, have to have a different construction. This requires very expensive and costly tools for the production of these containers and a high risk of fracture of the articulation arrangement under load.
An additionally known construction of a container--according to DE-OS 34 44 477--consists in that on a base part, wall parts are articulated on its encircling marginal sides, which wall parts are able to be folded from a vertical position in righted state to the base part into approximately the plane of the base part. The articulation of the wall parts onto the base part takes place in this embodiment by means of impressions in the material along the fold lines, which form so-called film hinges. In the righted state, the wall parts are positioned by means of connecting arrangements, in particular plug connections, in their position with respect to each other. A disadvantage in this embodiment is that through the impressions, the stability of these containers is impaired and therefore these are better suited for application in apparatus construction for the incorporation of functional elements etc. than for use as transport containers of commodities and goods.
It is now an object of the invention to create a container which takes up a small transportation volume or storage volume in empty state and which, when used as a transport container is distinguished by a large holding capacity both in volume and also in weight of the goods to be carried, and which requires a small number of components.
This object of the invention is achieved through the features quoted in the characterising clause of claim 1. The surprising advantage here is that through the arrangement of the locking elements in the region of the end faces of the wall parts, the latter form with the wall parts approximately one plane and hence no additional space requirement is necessary on transportation or storage of the containers and that through the construction of the locking device with the pre-stressing force acting in the engagement direction, an unintentional loosening of the coupling devices is effectively avoided.
However, an embodiment according to claim 2 is also possible, because thereby even in containers, which have a greater depth through corresponding height of the side wall parts, a secure connection or arresting and positioning of the wall parts with respect to each other is achieved.
An embodiment as described in claim 3 is advantageous here, whereby a high stability of the connecting arrangement is achieved, which makes possible a high lateral load of the wall parts by the material carried by the container.
However, an embodiment according to claim 4
