DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a storage container, preferably a storage tray of plastic having detachable partition walls. The container is provided with opposite vertical recesses or pairs of vertical ledges along the inner side of the two long sides.
Storage containers of this kind have been produced previously with varying shape of the container and the partition walls. These containers have been provided with opposite vertical recesses or pairs of vertical ledges along the inner side of the container. Then the partition walls have been inserted vertically from above into the ledges or the recesses. However, at the designing of such storage containers there are often problems with the sides of the container, since they are not rigid enough. When the container has been filled with a certain amount of goods the two long sides are pressed outwards, whereby the detachable partition walls are coming loose from their holds. Containers which are placed on a shelf will also be squeezed against each other. This prevents a container from being pulled out.
The purpose of the present invention is to decrease or to set aside these drawbacks of the prior art.
According to the present invention a storage container, preferably a storage tray of plastic having detachable partition walls has been brought about. Along the inner side of the two long sides the container is provided with opposite vertical recesses or pairs of vertical ledges.
The storage container comprises an inwards directed horizontal ledge along the inner side of each of the two long sides. Locking means are arranged in the upper edge of the ledges on the two long sides of the container in connection with each recess or pair of ledges. The partition walls comprise a lower part and an upper part connected to each other by an integrated hinge, whereby the parts are made of plastic in one piece. The upper part is provided with locking means along each short side, which locking means are intended to co-operate with the locking means on the container.
The partition walls are installed in the container by inserting their two vertical edges into the recesses or between the pairs of ledges. Then the upper part of the partition walls is folded along the hinge at an angle with the lower part in such a way that the locking means on the partition wall are brought into engagement with the locking means on the container. Preferably the upper part of the partition walls is folded at an angle of about 90.degree. with the lower part of said walls.
Usually the container is made of plastic such as polypropylene, polyethylene or impact resistant polystyrene. However, polypropylene is preferred due to its sound absorbing properties.
As mentioned above the storage container is provided at the top with an inwards directed horizontal ledge along the inner side of each of the long sides. These ledges assist in taking up strains which the container is exposed to at the use thereof. Moreover, the ledges contribute to a more rigid construction of the container.
Suitably the locking means on the container and the partition walls respectively co-operate by snap-in action. Then, preferably the locking means of the partition wall consist of snap-in heads while the locking means of the container consist of recesses in the upper edge of the inwards directed horizontal ledges on the container. Usually these recesses consist of through going vertical holes in said horizontal ledges. Of course the shape of the recesses is adapted to the shape of the snap-in heads. In this way a partition wall which has been attached to the container will increase the rigidity of the long sides of the container.
The lower part of the partition wall is provided with recesses at the top corresponding to the shape of the ledges on the long sides. The vertical edges of the partition wall will thereby fit tightly to the long sides of the container. Preferably the lower part of the partition wall is provided with a label holder at the top. Then a label placed in the label holder will be kept in place when the u
