BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION AND PRIOR ART
This invention relates to a container of the type comprising a bottom, a foldable wall arrangement and a lid. The container may have the character of a box, receptacle etc. with very varying size and is intended to be used for transport and storage of goods of very varying types.
Such containers have to be foldable so as to occupy a minimum of space during transport without goods or storage. According to the prior art the lid, the bottom and the wall arrangement are present as separated elements in the folded state of the container. These elements are generally arranged in big numbers in any suitable container for transport or storage. However, this incurs according to the experience considerable troubles to once again unfold or erect the different containers, since one has to select container elements fitting together from a greater collection of elements, which furthermore may contain containers of different sizes. The problem is accentuated by the fact that often separate elements or even a bigger number of the same may be lost during transport or storage. Furthermore, there is a considerable risk of damages of the container elements, and in particular their edge garnitures and interlocking means, when the elements are transported or stored disordered upon each other in stacks.
SUMMARY OF THE INVENTION
The object of the present invention is to point out constructive ways to reduce the problems mentioned above and accordingly provide a container with improved properties for transport and storage and a reduced risk of damages in the folded state.
This object is in accordance with the appended claim 1 obtained by that a locking arrangement included in the container and having locking means on the lid and/or on the bottom member is arranged to interlock the lid and the bottom member in the folded state of the container, and that the lid and the bottom member form a space therebetween in the interlocked state, in which the folded wall arrangement may be received. Thus, all elements of the container will in accordance herewith form a continuous unit in the folded state of the container, so that when the container has to be unfolded again after transport or storage, the operator knows for sure that the elements held together belong to one and the same container. It will of course primarily be the wall arrangement that get a protected position through the interconnection, but besides that will also the lid and the bottom be to a smaller extent exposed to damages as if they were completely separated.
The object aimed at is in accordance with the solution defined in claim 14 obtained in a container, which on the lid has locking means so as to cooperate with the wall arrangement for interlocking the lid and the wall arrangement in the unfolded state of the container, by that the locking means arranged on the lid are also arranged to cooperate with the bottom member so as to interlock the lid and the bottom in a position when the wall arrangement is removed or folded, said lid and bottom being substantially closer to each other in this position than when the container is unfolded. Thus, the problems mentioned in the introduction will also here be reduced by that the lid and the bottom are interlockable during transport and storage, and a particularly remarkable feature is the fact that the same locking means, which in the unfolded state of the container serves to interlock the lid and the wall arrangement, also serves to interlock the lid and bottom in the folded state of the container. This multiple use of the same locking means for fulfilling to locking tasks leads to a comparatively simple and uncomplicated construction. Although, it would be possible to transport and store the folded wall arrangement as mechanically not held together with the interlocked unit formed by the lid and the bottom within the scope of claim 14, there is also an improvement to enclose the folded wall arrangement in a space between the interlocked lid and bottom elements.
