Abstract

A reusable packaging system has a plastic container for receiving objects. The container (1) consists of separable elements (2, 3), such as tray-like base and top elements (2) and wall frame elements (3), constituting module elements in a modular system. The module elements (2, 3) have an element-compatible interface configuration at their periphery such that different module elements of the system, and in particular also elements external to the module system defined according to form, size and design of the individual modules, may only be joined to other module elements via the compatible interface configuration.

Description

Reusable packaging system.

Technical field

The invention relates to a reusable packaging system comprising reusable packaging according to the critical feature of claim 1.

BACKGROUND OF THE INVENTION

In the field of packaging technology, as before, mainly for consumer goods cartonage dominates as packaging material. In cartons, packed goods usually go as a unit folded on pallets to retail, while goods on pallets are usually secured with adhesive or clamping strips or shrink wrap. in this system, except for shrink films, adhesive tapes, etc. as waste products also cartonnage, whose share in the total waste generation in Germany is estimated at several 10,000 t per year.As the ever-increasing environmental regulations aiming, in particular, to take account of ever-decreasing disposal capacities, in the field of packaging, they are seeking concepts that would replace the existing disposable packaging with reusable transport systems.

To implement such a transport system repeated

These are monitored by the use of reusable containers in connection with the circulation of these containers to be minimized if

Possible additional transport volumes arising from the return to the 'manufacturer', or possibly 'to the store'. -Only, the purpose is to design, in particular, containers which can be decomposed or stacked with space saving Container systems, the volume of which can be freely varied by assembling the various modular containers, have also been presented.

The concepts of transport containers made up of individual reusable module elements are known. However, these concepts are adapted only to belonging to one system of individual modules, so that a combination with modules of other systems is not possible. In addition, modular elements defined by the shape, size and design of one system cannot be combined with the modular elements of another system into a transport container for reuse.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a possibility which can be carried out in a simple and inexpensive combination of different modular modules

systems.

This object is achieved by the characterizing part of claim 1, further modifications of the invention as indicated in the dependent claims are expedient

According to the purpose of the invention, suitable modular elements, such as bottom and / or tray-like lid elements or wall frame elements, at the periphery of the respective element have such an interface configuration that the individual elements can be joined independently of their general shape, size and design with other module elements using compatible interface configurations.

According to a preferred embodiment of the invention, the interface is arranged in the region of the upper edge of the modular element as a tongue and groove joint, which is preferably shaped as immediately adjacent tongues and recesses.

particularly smooth, in the shape of an inclined surface

The surface area c corresponds to the slope and recess offset from the habits of those inclined surfaces, which are the alder tongues of the interface and are preferably

The tongues and recesses engage in corresponding recesses of the opposite module element so that the overall is achieved

For this purpose, tongues and recesses may be distributed over the entire width of the interface edge. They may also be narrower than. interface edge width. In this connection, the edge of the interface can, in particular in the case of modular elements which are designed as bottom or lid elements, be shaped as an outwardly protruding contact strip.

In order for the inner edge of the container to have a uniform height, it is advantageous to provide at the outer edge of the interface edge with tongues and recesses that are narrower than the wall thickness of the interface edge.

In order to improve the manipulation of the modular elements during assembly, the languages of choice are preferably conical. In the above-described arrangement of tongues on the edge, however, their outer surfaces are preferably with straight outer walls of the container. In this case, the tongues and recesses contribute outside the lateral surfaces of the tongue-recess.

Furthermore, in parallel to the conical design of the inclined surfaces, only the internal outwardly directed shaping of the tongue surface advantageously enables trouble-free lids / bottoms of homogeneous elements.

the tongues and recesses are preferably dimensioned such that the corresponding upper edge of the tongues abuts the corresponding recess surface and thus contributes to the assumption of part of the load exerted by the stacked modular elements.

With regard to the configuration of the interfaces, it is advantageous for both manufacturing and shape reasons to always predict the language and recesses in the immediate vicinity as configuration elements of the interface. A number of these languages / recesses are predicted evenly in a row i.e. alternating sequence around the periphery of the interface. In particular, the arrangement in a row allows for a further degree of freedom for the connection possibilities, since the modular elements can be arranged in two positions relative to each other, which arise by rotating the elements 130 ° about the vertical axis of the container.

For the illustrated embodiments, it is advantageous to arrange two pairs of tongues / recesses equally on the circumference on each side in a rectangular container. .......

--A-should-be "nezaručlTcr ~ ^g ~ pp'uze 5ež.oěčné connection or -SAFE stacking of modular elements can be characterized by additionally configuring the interface suitably arranged switching prvky.Jedná example the plug and latches disposed at the interface region These assure in particular the semi-circular, partially undercut latches that are also anticipated on the outside of the vessel and are

A 'se / | Also, according to another preferred embodiment, semicircular spigot extensions in a semicircular depression can be envisaged in the interface region, which complement the corresponding embodiment of the oppositely arranged modular element and form two semicircular studs which are adjacent to one another. These ring elements may preferably be so-called original snap rings, which snap into the groove on the side of the pins, for example, in such a way that the disengagement of such rings is possible only by breaking them. also preferably a hot water-soluble adhesive joint is conceivable.

Especially when using the volume reduction at backward compatibility of here the frame transport elements of the foreseen walls that are for hinged, an interface configuration is required to allow the wall frame elements in the tilted position to conform to the shape of the interface. It is advantageous to design the bolting in the region of the corresponding latches, which cooperate on the side of the walls, so that the elements of the state are fixed. · ’

Furthermore, because of the particularly rigid design, the ribs are advantageously guaranteed.

The wall elements necessary for the stability of the open frame elements of the individual frame elements by means of a suitable longitudinal arrangement are rigidly connected to each other and which are preferably sprayed onto the side of the individual wall elements.

In addition to the transverse ribs, which are preferably connected at an angle of 30 °, the purpose of avoiding, for example, the carton on the inwardly converging inner one is prevented. _; The ribs are formed from the edge of the frame element starting at the tip and are shaped such that the objects to be loaded divert from the bottom of the frame element. longitudinal ribs and loading activity.

Another aspect of configuring the interface to stack the bottom and lid elements made in follows from the ability to shape the tray. These are equipped with <gak. already. indicated above, preferably orbiting the interface, at its upper edge an interface is formed. The side wall extending from the contact strip to the lid / bottom is preferably conical in order to cooperate appropriately in stacking with also conically shaped interface languages. In this sense, in order to create an optimized load-receiving surface and thus more secure stacking, According to a preferred further development of the invention, it is envisaged to provide conical, non-leaky tray-like bottom / lid elements, which in particular form corner areas of the recesses.

a corner region when stacking a region of the enlarged load-receiving area. in the corner, no languages and none are foreseen for this case

In total, the proposed interface configuration fits independently of the design of the individual modular elements securely joined together, or the languages / recesses as recurring, to shape and produce combinations of interface elements, on size, overall shape and elements to close the respective elements. The designed as well as their arrangement allows compatible interface design and thus connection of various elements.
