Description

Collapsible container

Always occurs when manufacturing, storing and transporting goods again the problem of using the available storage space to the greatest possible extent. Storage and transportation large quantities of small parts is usually accomplished by placing the parts in containers with appropriate measured size and shape. The containers are then removed using forklifts, trolleys or such as promoted further. These containers are usually made of metal or wood and are therefore correspondingly large and heavy and cannot be dismantled for storage purposes.

In contrast, the invention aims to provide a container for storing and transporting unpackaged or packaged parts to create, wherein the container is characterized by improved properties and economy target.

Another object of the invention is to provide a container which has side walls that can be dismantled and collapsed, which can be quickly removed from a pallet assembly and stored flat on top of each other when the Container is not used, so that valuable storage space is saved.

The invention also aims to create an economical, simply constructed container, which is on the one hand by low weight and on the other hand by a high degree should excel in terms of stability.

Another purpose of the invention is to provide a method for quickly assembling such a container.

According to the invention it is provided that a collapsible container a horizontally lying pallet arrangement with it has upstanding side walls that are releasably attached to eggs Pallet assembly are fastened by several circumferentially arranged barbs or the like, so that a storage

container is formed with an open top. After assembling a flat base plate is inserted tightly between the side walls in order to lock them outwards to press with the barbs. Furthermore, reinforcement rails are placed on the upper edges of the side walls by means of barbs attached.

Further advantages and features of the invention emerge from the claims and from the following description and the drawings in which the invention is explained and illustrated in detail. Show it:

A collapsible container 10 according to the invention, see

-4-309837 / 0502

1 and 3, in particular, has a horizontally lying bottom part or a fold arrangement 12 which is made of a substantially rigid material such as steel or wood a loose, flat base plate 16. The pallet is rectangular and consists of a flat base plate 18 with an upstanding rim or flange edge thereof 20 which runs around the base plate and at their edges 22, see FIG _o 5, is fixed accordingly.

Two support feet 24 are attached to the underside of the pallet 12, which are provided with runner surfaces 26. The feet are each reinforced by ribs 28 that are so far apart that openings are formed which are suitable for receiving fork legs, with which conventional fork or Forklifts are provided. The feet can be beveled downwards, see Fig. 5, in order to stack them vertically of pallets when the containers have been taken apart for storage,

The jacket or the wall structure 14 can be made of a conventional corrugated cardboard material that is fire-hammering and Has a water-repellent finish »For example, material from the Laminite Department of Tri-Wall Containers Inc., Long is suitable Iceland, New York. The abutting side walls, which form a collapsible jacket, are at their vertical

309837/0502

th edges articulated to one another by conventional fold lines · As Figo 3 and 5 show, the set-up is Sheath suitably sized and shaped so that it fits snugly into the boundary formed by the circumferential flange 20 fits and abuts against the base plate 18 with its bottom edges 30.

The side walls are pressed outwards against the pallet flange 20 by a base plate 16 made of corrugated cardboard, which forms a holding means which prevents lateral movement of the side walls with respect to the pallet. As shown in FIGS. 3-5, the pallet flange has a plurality of connecting and securing means, namely pointed, barbed tongues 32, which penetrate into lower parts of the side walls, around the jacket in its Position to lock against the pallet assembly 12. After the bottom plate 16 is inserted into the container, See Fig. 2, the side walls are in locking engagement with the tongues 32 pressed.

The tongues can be produced by using a triangular punching tool, not shown. The tool is struck accordingly so that with each tongue an apex 34 points downwards opposite the pallet 12. the Tongues therefore resist an upward movement of the side walls with respect to the pallet arrangement. Like Fig. 3 shows, the tongues on each side of the flange are preferred

-6- 309837/0502

arranged so laterally spaced that they on the gaps between the tabs on the opposite side are aligned. The tongues can therefore be used during reconstruction of the container and after rotating the jacket by 180 ° compared to its original in a whole area of the corresponding Penetrate sidewall.

The upper edges of the side walls can be reinforced by U-shaped rails 38 placed on them. Form the rails therefore reinforcing agents that strengthen the edges and protect against wear, fire and moisture. Simultaneously they increase the strength of the containers when they are stacked vertically on top of one another. The rails are also included a plurality of tongues 40 which, like the tongues are designed so that they can penetrate the underlying side walls to secure the rails. the The length of each rail is preferably approximately less than that of the corresponding side wall located underneath, see Fig. 1. This ensures the greatest possible protection of the upper edges without the foldability of the side walls for storage purposes.

The assembly of a collapsible container according to the invention is described below.

First, the pallet 12 is arranged horizontally. Then the jacket 14-, which is usually in the collapsed, in the

309837/0502

essential flat state is stored, to which in Fig. 1 shown cuboid. The coat is on the Pallet set so that the lower portions of its side walls lie directly on the tongues. The The jacket is inserted into the space delimited by the flange 20 in such a way that its bottom edges 30 are against the base plate 18 bump. Then, see Fig. 2, the bottom blocking plate 16 is inserted into the compartment bounded by the jacket and after pressed down until it rests against the base plate.

By pressing the holding plate 16 between the side walls, a pressure is exerted on the side walls, so that this outwardly into locking engagement with the tongues 32 that penetrate the side walls. Instead of the corrugated cardboard, other material can be used, which allows penetration of the tongues and, by receiving the tongues, causes the side walls to be in a locked position being held. The edges 42 of the retaining plate secure the rectangular shape of the shell and prevent horizontal movement of the side walls, while the pointed tongues pointing downwards make a vertical upward movement prevent the coat. The rails 40 can be on the upper edges the side walls are attached before or after the sequence of work steps explained above. Have attempts has shown that a container according to the invention in a standard size has a load capacity of more than 1800 kg Has.

309837/0502

The side walls 14 are of the pallet assembly 12 for Removes subsequent storage by reversing the assembly procedure described above. in the individually, the holding plate 16 is first removed and the side walls are detached from the tongues 32 by removing the side walls are pressed towards each other inwards. After removing the jacket, it is folded flat and with the retaining plate 16 stored without taking up any significant memory space.
