Description

The The invention relates to a stackable storage and transport container for storage or for one-way and multi-way transport of goods of all kinds, especially of small parts.

charge carrier be as transport and storage containers especially there used where tools or components in the context of a manufacturing process transported or stored. she usually consist of metal sheets or plastic sheets, the glued, welded or form-fitting with each other can be connected. It is next to a sufficient Capacity and life also important that the container preferably no projections or heels have, which constrict the interior or otherwise obstructive are. Partially in the interior are additional inserts provided, although the interior is complete and without Lining projections, which, however, do not themselves have sufficient load-bearing capacity own and mean extra effort.

EP 0 674 595 B1 describes a stackable transport container with a self-closing upper edge. The container consists of a uniformly strong, foldable container molding with a bottom, two upright end walls, two upright side walls and four end flaps. The side walls and the end walls have downwardly folded tabs over which an upper edge is inserted, which automatically engages the tabs.

Out DE 295 17 978 U1 For example, a charge carrier is known in which the side walls are hollow-chamber plates made of thermoplastic material. The upper edges of the side walls are provided with a carding edge, which is integrally formed on the side walls and formed by a rigid fold of the Hohlkammerplat te. This forms a circumferential cavity. The lower end of the carding edge is separated from the side walls by an open joint. On the sides and corners of the side walls are held together by means of connectors by edge, fold and side connector form-fitting. The described carrier has a complicated structure with many projections and edges and heels. Its production is very complicated by the many items.

US 2 544 283 A describes a transport container from a folded fitting. It has an upper edge with a lip at the bottom, which engages in the side flaps of the erected container. The border consists of two areas, which are held by connecting brackets.

disadvantage the aforementioned transport container is that this through Thermal edges manufacturing technology are very expensive. at the use of hollow panels affects the restoring force of the hollow chamber material using a single scribe line (KissCut) or a film hinge inserted circumferential Stack profile negative by spreading it. Besides, they are increased material costs for additional below hinged flaps along the side walls required.

task The invention is a storage and transport container to suggest, on the one hand a low weight, on the other hand but has a high stability and possible has few projections and heels. Furthermore It should be easy and inexpensive to produce be.

According to the invention the problem solved by the features of claim 1. Ausgestaltende features are in the dependent claims 2 to 10 described.

Of the Storage and transport container consists of a one-piece and foldable container molding. The container fitting has a base, two side walls hinged around a fold, two end walls hinged around a fold, four on the side walls or the end walls folding around a fold inward Corner flaps. For a rectangular storage and transport container the side walls are always on the longer sides arranged. With a square cross section, it does not matter what as a side wall and what is called a front wall. The four corner flaps can also be located on the end walls. Always two of the corner flaps should be advantageously so long that they are in the folded, upright state equal to the entire side length they cover up. As a result, they should always be arranged on the longer wall. As on the front pages then there is a double thickness of material, it is advantageous if on this page also possibly existing handles provided are. This results in a high stability and a high load capacity reached.

The Foldings are grooved, embossed, rolled or scratched. Preferably a plotter is used, the contours of the entire container molding generated.

at the production of the contours of the container molding are from the top of the up side panels and / or the upwardly folding end walls each have a plurality of tabs formed. The number and dimension of the tabs is determined according to the desired load capacity of the storage and transport container.

The tabs are always at the bottom, the Floor facing edge as well as cut out on one of the two sides. The second side edge has a score or at least a fold, so that the tabs can be folded laterally around the score to the spacers between the tabs. The tabs can be folded both inwards and outwards. An inward flaps but associated with additional effort and disadvantages, since the container molding should first be rotated and scratched on the back.

The Width of a tabs should preferably equal to the porridge te a Corresponding intermediate piece between the tabs.

Preferably each in the middle of a page, the tabs can For reasons of symmetry also in each case according to one set side so that they strike like a window sideways.

Around the upper edge, the sections by the folded tabs is formed double thick, is a bottom open stacking profile attached. The stack profile is U-shaped. It has two legs, an inner leg and an outer leg, wherein on the outer leg inside a hook edge is formed. The hook edge is mounted at a height that he under reaches the bottom of the tabs and hooks there. The hook edge can by an angle α <90 ° after be formed inclined above. The stack profile snaps through it automatically over the edge of the upright Side and end walls and is securely locked.

For a good stackability of multiple containers, the stacking profile have a stack edge. Preferably, this is complete circulating.

For a high load capacity can be several or even all tabs with the spacers to which they are folded be connected areally. This can be done, for example a bonding done. It is particularly advantageous if the container molding made of thermoplastic material and the tabs on the Intermediate pieces are welded. Both surfaces are thereby exposed to a long hot air until their Liquefy surfaces and by joining together merge. This will be a permanent and resilient connection produced.

Especially It is advantageous if the container molding made of plastic hollow panels. Plastic hollow panels consist of two spaced outer walls with intermediate webs or honeycombs. When using plastic cellular sheets The folds are on the inside of the container wall attached and thus generates a predetermined bending point. Outside is the container at the folds only bent and thus locked. This results in a closed container without sharp edges.

at Hollow chamber panels, the scribe is formed at the tabs by that the inner plate wall and the webs or honeycomb cut open are, so that the tabs easily by hand around the side edge let bend.

ever according to the desired load capacity, it is also possible that a storage and transport container completely or partially made of corrugated or aluminum honeycomb material.

at the described embodiment is a preferred variant of a container for the Storage and transport of small parts for automobile production. The finished storage and transport container should be one size of 800 × 600 × 250 (L × W × H in mm).

1 shows the top view of a container molding. It consists of a one-piece, 5 mm thick plastic hollow panel. By means of a plotter, a contour is created, leaving a floor 1 , two at a fold 6 hinged side walls 2 and two at a fold 5 folding end walls 3 arise. On the two side walls 2 two are each about a fold 7 inside hinged corner flaps 4 educated. The absolutely parallel course of all edges is important. The corner flaps 4 are so long that they are in the folded state, the width of the front wall 3 cover. At the corner flaps 4 are recesses 11 for the later usable handles 18 , Also in the two end walls 3 are each handle recesses 10 incorporated. The folds 5 . 6 . 7 are also grooved with the plotter.

From the top of the side panels that fold upwards 2 and the hinged up end walls 3 are each 6 or 5 tabs 8th formed.

The tabs 8th are at the bottom bottom edge 19 as well as at one of the two margins 20 cut out. The second margin has a scratch 9 so the tabs 8th sideways around the scribe 9 to the intermediate pieces 17 between the tabs 8th can be folded outwards. The width of the tabs 8th is equal to the width of an intermediate piece 17 , At the end walls 3 become the middle tabs 8th for reasons of symmetry, each folded to an opposite side.

The height of the side walls is higher than the height of the corner flaps by the width of the flaps. This is also in 6 clearly visible.

The 2 shows a storage and transport container in individual parts with already folded container molding. In the two handle recesses 10 and the four recesses 11 in the corner flaps are handles 18 used. The handles 18 are made in two parts and have a circumferential groove, which corresponds to twice the thickness of the hollow chamber plates and a snap mechanism. The two handle halves are in the handle recesses 10 used and snapped together. By inserting the handles, the corner flaps 4 on the end walls 3 held, so that an additional lock is not necessary.

3 shows a partially folded container molding. It can be seen how the tabs 8th to the intermediate pieces 17 be worked out. The crack 9 at the tabs 8th is generated by the inner plate wall and the webs or honeycombs are cut. The outer panel wall remains standing. It is possible that this is also scratched. The tabs 8th can be easily bent by hand around the stalled slab wall. For a high load capacity all tabs 8th with the spacers 17 welded by hot air.

To the upper edge, by the folded tabs 8th Sectionally double thick, is a bottom open stack profile 12 attached. The two 4 and 5 show such a stack profile 12 , In 6 is an attached stack profile 12 seen.

The stack profile 12 is a plastic continuous casting and U-shaped. It has an inner thigh 14 and an outer thigh 13 , On the outer thigh 13 inside is a hook edge 16 formed. The hook edge 16 is mounted at a height that he below the bottom of the tabs 8th ranges and hooks there. The hook edge 16 is formed by an angle α = 80 ° inclined upward. The inner thigh 14 is slightly bent inwards. This is when placing the stack profile 12 a slight spread possible. Also with the attached stack profile 12 a tension is generated, which ensures a secure fit of the hook edge 16 guaranteed. The stack profile 12 thus automatically snaps over the edge of the upright side walls 2 or end walls 3 one.

For a good stackability of multiple containers has the stack profile 12 a circumferential stack edge 15 , The stack edge 15 closes on the outside and is so wide inside that the next storage and transport container can be placed form-fitting. For reasons of material savings is the stack edge 15 hollow.

Of the Storage and transport container owns by its few Components a low weight, on the other hand, a high stability. He has little projections and heels. The Container molding can be completely Plotting or punching. This is an exact compliance with the dimensional accuracy through contour accuracy when plates or punching possible, which low manufacturing tolerances are possible. The container is therefore easy to produce and inexpensive. Since no thermal edging must be done, no thermal edging required. Due to the novel attachment the stacking edge through the areal connected tabs is a high strength achievable. The locking of the stack profile then takes place without restoring forces of down bent tabs. The installation of the stacking profile is facilitated and is safer. Additional material for mounting edges is avoided.
