Description

The invention relates to a stackable transport and storage container, which consists of at least one base, two side walls and two end walls and inner compartments and / or a container cover.

Such transport and storage containers are used in particular where tools or components are to be transported or stored as part of a manufacturing process. They usually consist of metal sheets or plastic plates which are glued, welded or positively connected with each other. It is also important in addition to a sufficient load capacity and life, that the container as possible have no projections or heels that constrict the interior or otherwise obstructive.

Although metal containers are relatively stable, they are often very heavy, susceptible to corrosion and noise when used. Plastic containers have the advantage that they have a relatively low weight. On the other hand, they often have low stability, which is compensated by additional reinforcements.

For comparable applications, injection molded containers as well as containers made of PP hollow chamber material of different designs are known. The injection-molded containers are containers produced in elaborate shapes. These can only be produced effectively in large quantities due to the high tool costs.

Comparable PP hollow containers are characterized either by the fact that they are assembled from many individual parts, which require a large number of individual steps or by simple folding and bending constructions, which are held in shape by means of a circulating stack profile. Thermal bending, ultrasonic welding, bonding technology and other joining and machining operations are used here. Basically, the containers are characterized by the fact that thanks to low tooling costs, smaller quantities of different dimensions can be produced.

EP 1 505 001 A1 describes a stackable charge carrier made of thermoplastic material for storage or for one-way and Mehrwegetransport of small parts of all kinds. The load carrier is always made of thermoplastic material. He has a bottom and usually four side walls, which are made of a flat output plate. This output plate is preferably a hollow chamber plate.

Between the bottom and the side walls, a line-shaped notch is inserted, around which the side walls are foldable into a box-shaped base body. The abutting vertical edges of the side walls are welded. At the upper edges of the side walls includes a carding edge, which is folded around a line-shaped notch in the output plate by 180 ° to the respective side wall. Above the carding edge, a stacking profile is positively clipped in such a way that a projection formed on the stacking profile fixes the stacking profile on the carding edge.

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.

Horizontal forces are absorbed by the circumferential, one-piece upper edge and by additional corner reinforcements or plug-in corner profiles. For each container size thus each separate edges must be provided. The manufacturing and assembly costs are very high due to the many additional corner pieces.

Folded containers with a top circumferential stacking edge are, for example, in DE 10 2015 115 592 B4 and DE 10 2010 037 517 B3 described.

Internal installations in transport and storage containers can be fastened to the insides of the containers with additional fastening devices, for example Velcro strips or rails.

102011055676 A1 describes a multiply reusable transport pallet for piece goods. Bulk goods receptacles which can be used in the pallet are fastened by guide rails with receivable piece goods strips.

A welt is the edge reinforcement of a textile or a foil. The piping has a round cross section and for the purpose of attachment a wide flat welted flag. This is the connection between textile / foil and piping. Often, the piping flag is a sheath, which holds the Kederwulst in itself. Keder flag and the textiles or films to be fastened are usually welded or sewn together.

As a piping rail is called the part of clamping mechanisms in which the piping is introduced. This is a cross-sectionally round guide, in which the piping can be inserted and moved along without friction. The piping and piping rail thus make it possible to stretch a tarp or similar fabric flat across the edge line.

A piping rail is often used in outdoor advertising, tent construction or large screens.

The installation of the piping rail is very easy, because it can be glued or screwed depending on the application. In a field of application in which high tensile forces can be expected (wind, etc.), a screw is inevitable. For safety reasons, we recommend always screwing the rail. The holes can be easily drilled yourself.

DE 20 211 459 U1 shows a tray with flexible compartment compartments for installation in a container. It consists of an insertable into the container support structure and associated flexible compartment compartments. The flexible compartments can be positively and positively connected by means of a plug-in system with the support structure. The support structure consists of two spaced apart transverse and longitudinal struts, which have tabs which are inserted into slots in the crossbars. The flexible compartment compartments are arranged between the transverse and longitudinal struts. In a particular embodiment, the compartments are reinforced at the upper edges by a Kederprofil.

DE 9 408 451 U1 relates to an airbag for lining a stiff-walled transport container. At least one additional retaining element is formed at the upper edge of the airbag, which is detachably connectable to the edge or inner surface of a transport container side wall.

The G 93 11 040 shows a bolted to the inner surface of the transport container side wall Kederprofil, in which an air bag can be hung with a formed at its upper edge rubber cord.

The above-mentioned mounting options require as connecting structures additional installations that increase the production cost. In addition, they usually narrow the clear cross section of the container in addition.

The object of the invention is to propose a transport and storage container, in which inner compartments and / or a container cover can be releasably secured to the container without the aid of tools and additional fasteners. In this case, as few projections and paragraphs should limit or constrict the interior of the container. The production and assembly should be possible with little effort.

According to the invention the object is achieved by the features of claim 1. Ausgestaltende features are described in the subclaims 2 to 6.

The transport and storage container consists of at least one base, two side walls and two end walls and inner compartments and / or a container cover. The side walls and the end walls have carding edges, which are each foldable around a fold line to the associated side wall and end wall. About the carding edges of the side walls and the end walls open stackable profiles are attachable. These stack profiles have an inner leg, an outer leg and a molded on the outer leg or inner leg hook edge. This hook edge is snapped in the attached state over the end of the folded carding edge of the side walls and the end walls.

The connecting web between outer leg and inner leg forms a stack support. The stack profiles have a molded on the outer leg upper stack edge.

According to the invention, the connecting web forming the stack support between the outer limbs and the inner limbs of the stacking profiles has a profiling which is designed as a welt receptacle. In this Kederaufnahme a Einzugsskeder with a Kederkern and a Kederfahne can be inserted. In this case, the compartments for receiving transport and bearing parts and / or the protective cover are attached to at least one Kederfahne.

In a preferred embodiment, the stack profile is a plastic continuous casting. Depending on the size of the transport and storage containers, the stacking profiles can be inexpensively produced and cut in large quantities.

A preferred embodiment is when the rotating stack profile consists of a continuous, multi-part profile. The individual, rotating parts of the stack profile are at the corners of the transport and storage container to a fold line outwardly hinged so far that in the Kederaufnahme a feeder line is inserted. The stack profile has here in the region of the corners V-shaped recesses, which allow an inwardly fold the individual stack profile parts by about 90 °, so that they strike flush with the adjacent part of the corresponding stack profile.

If the stack profile is formed in 5 parts, the first can be butt-joined to the fifth part of the stack profile in the plugged-on state, for example by welding or by gluing.

The bottom, the side walls, the end walls and the foldable carding edge are preferably made of plastic Strukturkammerplatten. Structural chamber panels consist of two spaced cover plates with intervening, designed as knobs connecting webs. When using structural chamber panels, the fold lines are attached to the inside of the container wall side and thus creates a predetermined bending point. Outside the container is only bent at the fold lines and thus closed. This results in a closed container without sharp edges.

In structural chamber panels, the scribe is formed at the carding edges by cutting open the inside panel wall so that the tabs can be easily bent around the side edge.

To save material and to reduce weight of the outer leg and inner leg of the stack profiles connecting connecting web may have a cavity.

The transport and storage container preferably consists of a one-piece and foldable container molding. The container molding has a bottom, two foldable about a fold line side walls and two hinged around a fold line end walls. The fold lines are grooved, embossed, rolled or scratched. Preferably, a plotter is used, which generates the contours of the entire container molding.

In the production of the contours of the container molding each carding edges are provided at the top of the upwardly folding side and end walls, which are preferably in each case foldable inwardly by a score or to the associated side wall and end wall. The carding edges can be folded inwards as well as outwards.

To the upper carding edge, which has by folding its double wall thickness, the open bottom stack profile is attached. The stack profile is U-shaped. It has two legs, an inner leg and an outer leg, wherein on the inner leg inside a hook edge is formed. The hook edge is mounted at a height that extends below the lower edge of the carding edge and hooks there. The hook edge may be formed inclined at an angle <90 ° upwards. The stack profile thereby automatically snaps over the edge of the upright side and end walls and is securely locked.

In the case of an outwardly folded carding edge, the stacking profile is adapted such that the hooked edge hooks on the outer leg under the carding edge.

For a good stackability of multiple containers, the stack profiles have the same shape, completely circumferentially formed stack edges.

Depending on the desired load capacity, it is also possible that a transport and storage container consists entirely or at least partially of corrugated cardboard or aluminum honeycomb material.

The transport and storage containers have a low weight high stability and load capacity. The attachment of internal compartments and / or a container cover can be done without the aid of tools and additional fasteners releasably on the container. Even with massive blows on the sides, for example, by jerky pushing another box, the compounds can not solve. The area utilization of the container molding is very effective. The production of the stacking profiles is very material-saving. The profiles and injection-molded corners used can be standardized and inexpensively pre-produced and stored in large quantities.

In the described embodiment is a preferred variant of a container for the transport and storage of small parts for automotive production. The finished transport and storage container should have a size of 800 x 600 x 250 (L x W x H in mm).

The 1 shows a part exploded view of a transport and storage container with attachable stacking profiles 9 and one for protecting parts to be transported on the stacking profiles 9 attachable protective cover 16 ,

The transport and storage container is made of a foldable container molding. It consists of a one-piece, 5mm thick plastic Strukturkammerplatte. By means of a plotter, a contour is created, leaving a floor 1 , two around a fold line 21 hinged side walls 2 and two around a fold line 21 folding end walls 3 arise. On the two side walls 2 two are each about a fold line 21 inside hinged corner flaps 25 educated.

The corner flaps 25 are so long that they are in the folded state, the width of the front wall 3 cover and in the middle of the end walls 3 collide. At the corner flaps 25 are handle recesses for later usable handles 19 , Also in the two end walls 3 each handle recesses are incorporated. By inserting the handles, the corner flaps 25 on the end walls 3 held, so that an additional lock is not necessary.

At the top of the fold-up side walls 2 and end walls 3 are carded edges 10 molded, each by 180 ° inwards around a scratch 26 to the associated side wall 2 and front wall 3 are foldable. The Ritz 26 is designed so that the outer cover plate of the structural chamber plate is completely severed and the folding over the second, later inner wall takes place. The carded edges 10 do not have to extend across the entire width of the side and end walls.

About the cardboard edges 10 the side walls 2 and the end walls 3 are bottom open stacking profiles 9 attachable.

2 shows a single stack profile 9 , It is through an inner thigh 6 , an outer thigh 5 and one on the outer leg 5 or inner thighs 6 molded hook edge 8th formed in the plugged state on the end of the folded carding edge 10 the side walls 2 and the end walls 3 is restrained. The connecting bridge between outer leg 5 and inner thighs 6 makes a pile pad 20 for further, stackable storage and transport containers.
The pile pad 20 forming connecting bridge 22 the pile profiles 9 has an internal profiling that acts as a piping receptacle 12 is trained. The Kederaufnahme 12 is as close as possible under the stacking pad 20 to make optimum use of the container interior. At the same time enlarges through the Kederaufnahme 12 the bearing surface of the next charge carrier.

In the Kederaufnahme 12 is after 3 a feeder piping 13 retractable, made of a keder core 15 and a welted flag 14 is formed. The Kederkern is a round plastic profile. At the Kederfahne 14 , which may be a textile or a foil, are after 4 partitions 17 for holding transport and storage parts and a protective cover 16 attached. The protective cover serves to protect against contamination of the cargo during transport. The dust protection textiles or dust protection foils can be applied to the compartments 17 rest. Two protective covers 16 of textiles or foils may be opposite and / or overlapping on the compartments 17 rest.

The rectangular cavity 4 is necessary primarily for technological and economic reasons.

The 5 shows a section of a transport and storage container with integrable compartments of preferably relatively tight textiles, such as nonwoven fabric made of polyethylene, nylon and many more, directly with the Kederfahne 14 sewn. For films, this compound is preferably an adhesive bond. Films are also sewn or welded. The feeder piping can be a purchased part with piping core 15 and short welted flag 14 his. The sections 17 but can also be configured with attached protective cover 16 and intake piping 13 be obtained.

The stack profile 9 is a plastic continuous casting and U-shaped. The hook edge 8th is formed inclined at an angle of about 80 ° upwards. The inner thigh 6 is slightly bent inwards. This is when placing the stack profile 9 a slight spread possible. Also with the attached stack profile 9 a tension is generated, which ensures a secure fit of the hook edge 8th guaranteed. The stack profile 9 thus automatically snaps over the edge of the upright side walls 2 or end walls 3 on. The width of the carded edges 10 corresponds to the internal width of the stacking profiles 9 from its top stop to its hook edge 8th ,

For a good stackability of multiple containers has the stack profile 9 above a stack edge 7 , The stack edge 7 closes flush on the outside and is so wide inside that the next transport and storage container can be placed form-fitting.

The corners of the transport and storage container are welded together here.

In a preferred embodiment, the circulating stack profile 9 made of a continuous plastic profile, with its individual parts at the corners 23 of the transport and storage container around a fold line 11 are foldable outwards. This allows the feeder piping 13 in the Kederaufnahme 12 on the two opposite side walls 2 be inserted. Due to the in 6 illustrated V-shaped recesses 24 The stack profile parts are then bent inwards by 90 ° to the adjacent stack profile part.

The stack profile 9 is in 6 5-piece design. The first part comes with the fifth part of the stack profile 9 in the attached state butt-connected, for example by butt welding.

The 7 shows a completely assembled transport and storage container. He has by its few components a low weight, but on the other hand, a high stability. He has little projections and heels. The container fitting can be completely plotted or punched. As a result, accurate compliance with the dimensional accuracy by contour accuracy is possible, whereby low manufacturing tolerances are possible.

The piping rail was not simply placed on an existing profile, but in the stacking profile 9 integrated in turn to optimally use the interior of the transport and storage container.

The transport and storage container is by its few parts in a simple manner and inexpensive to produce, especially because no complex systems for miter cuts and no welding technology for corners must be purchased. Additional material for mounting edges is not needed.

The process times for pit production are considerably shortened. Poor welding of the critical corners is avoided. In addition, the profile bars can be used much better, since in each case a continuous section must be made. Thanks to the simple, lighter and cheaper parts, this type of container can be assembled on site with the simplest mounting means. From a central manufacturing facility, the end users can be supplied with the punched container moldings and only have to use the piping themselves and the stacking profiles 9 assemble.
