Description

Die Erfindung bezieht sich auf ein Gefache für Mehrwegeeinsatz mit unverlierbar (verliersicher) zusammengesteckten Längsseitenstegen und Querseitenstegen aus einem biegsamen stoßabsorbierenden Schaumstoff, wobei die Längsseitenstege Einstecklöcher zum Verbinden mit den Querseitenstegen aufweisen und an den Querseitenstegen zwischen einander gegenüberliegenden Einstecknuten Einsteckstege zum Einstecken in die Einstecklöcher der Längsseitenstege ausgebildet sind.The invention relates to a compartment for multi-way use with captive (captive) Long side bars and transverse side bars from a flexible shock absorbing foam, the long side webs Plug-in holes for connecting to the crossbars have and on the transverse webs between each other opposite insertion grooves insertion bars for insertion are formed in the insertion holes of the long side webs.

Gefache dienen als Verpackungsteil für Verpackungszwecke, beispielsweise als Einsatz in Behälter, Container, Kisten zum vereinzelten Verpacken von Artikeln.Compartments serve as a packaging part for packaging purposes, for example as an insert in containers, containers, boxes for occasional packaging of articles.

Behälter mit Gefachen zum vereinzelten Einsetzen von Artikeln werden vielfach in der Industrie benötigt, um in Fertigungsprozessen die benötigten Produktteile schnell und einfach zur Verfügung zu haben und um umständliches Ein- und Auspacken einschließlich Anfall von Wegwerfverpackungsmaterial zu vermeiden. Darüber hinaus sollen die Behälter mit Gefachen als Mehrwegeverpackung benutzt werden.Containers with compartments for the individual insertion of articles are widely needed in industry to Manufacturing processes the required product parts quickly and easy to have available and cumbersome in and out Unpack including any disposable packaging material to avoid. In addition, the containers are designed with compartments can be used as reusable packaging.

Bisher werden Gefache aus Streifen aus Pappe oder Wellpappe hergestellt, die jeweils kammartig einseitige Einschnitte aufweisen, mit welchen sie gegeneinander gerichtet zusammengesteckt werden. Diese Gefache sind jedoch nicht unverlierbar, d.h. sie können jederzeit leicht auseinandergezogen werden bzw. fallen von allein auseinander.So far, compartments are made of strips of cardboard or corrugated cardboard produced, each comb-like one-sided incisions with which they are directed against each other be put together. However, these compartments are not captive, i.e. you can easily at any time are pulled apart or fall apart on their own.

Darüber hinaus eignen sich Gefache aus Pappe oder Wellpappe nicht als Mehrwegegefache für einen mehrfachen Einsatz und zur Ersparnis von Verpackungsmaterial, da sie oft bereits bei ihrem ersten Einsatz beschädigt werden, naß werden oder auch Biegekanten oder Bruchkanten erfahren, wodurch ihre Stabilität verringert wird.Compartments made of cardboard or corrugated cardboard are also suitable not as a reusable compartment for multiple use and for Saving of packaging material, as they are often already at damaged, wet or even when they are used for the first time Bending edges or break edges experience, which increases their stability is reduced.

Es gibt bereits Gefache aus festen Materialien, nämlich Holz oder kompaktem Kunststoff, der zu Platten oder Hohlkammerplatten extrudiert ist. Diese festen und kompakten Gefache aus Kunststoff oder Holz werden ebenfalls mit einseitigen Einschnitten nach Art eines Kammes ausgebildet und gegeneinander gerichtet zusammengefügt, wodurch ebenfalls eine nicht unverlierbare Verbindung entsteht, d.h. diese Gefache können ebenfalls von alleine auseinanderfallen. Des weiteren haben sie den Nachteil, daß die Gefachseitenstege scharfe Kanten aufweisen und in keiner Weise stoßabsorbierend sind, so daß empfindliche zu transportierende Artikel an der Oberfläche verkratzen.There are already compartments made of solid materials, namely wood or compact plastic that can be made into plates or Hollow wall panels is extruded. These solid and compact Compartments made of plastic or wood are also included unilateral incisions formed like a comb and directed against each other, which also creates a connection that cannot be lost, i.e. these compartments can also fall apart on their own. Furthermore they have the disadvantage that the compartment side bars are sharp Have edges and are in no way shock absorbing, so that delicate items to be transported on the surface scratch.

Ein Gefache gemäß Gattungsbegriff ist aus der DE 42 07 515 A1 bekannt geworden, wobei die die Längsseiten bildenden Wände duchgehend einteilig ausgebildet sind, und die die Querseiten bildenden Wände aus Teilstücken, die jeweils nur ein Gefachabteil überbrücken, gebildet werden. Hierbei weisen die Querseiten an den mit den Längsseiten kontaktierenden Rändern jeweils zwei vorstehende Laschen auf, welche in entsprechende Einstecklöcher der Längsseiten eingesteckt und verrastet werden. Die Herstellung des Gefaches ist umständlich und durch die Laschen nur beschränkt stabil. A compartment according to the generic term is from DE 42 07 515 A1 become known, the walls forming the long sides consistently formed in one piece, and the transverse sides forming walls from sections, each one Bridge compartment, be formed. Here, the Cross sides on the edges contacting the long sides each two protruding tabs, which in corresponding Inserted holes on the long sides and locked become. The manufacture of the compartment is cumbersome and through the tabs are only stable to a limited extent.

Der Erfindung liegt die Aufgabe zugrunde, ein Mehrwegegefache zu schaffen, das stoßabsorbierende Eigenschaften, wie Wellpappe oder besser aufweist, das unverlierbar aufgebaut ist, d.h. das nicht von alleine auseinanderfallen kann und einfach herstellbar ist.The invention has for its object a multipath to create the shock absorbing properties like Corrugated cardboard or better, that built captive is, i.e. that cannot fall apart on its own and is easy to manufacture.

Diese Aufgabe wird gemäß der Erfindung mit einem Gefache für Mehrwegeeinsatz mit verliersicher (unverlierbar) zusammengesteckten Längsseitenstegen und Querseitenstegen aus einem biegsamen stoßabsorbierenden Schaumstoff gemäß den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst.This object is achieved according to the invention with a compartment for Multi-way use with captive (captive) assembled longitudinal side bars and transverse side bars a flexible shock absorbing foam according to the characterizing features of claim 1 solved.

Gemäß der Erfindung wird ein Gefache aus biegsamen elastischen Materialien vorgeschlagen, mit dem es möglich ist, ein Gefache unverlierbar aus Längsseitenstegen und Querseitenstegen herzustellen.According to the invention, a compartment is made of flexible elastic Materials proposed with which it is possible to create a compartment captive from long side bars and short side bars manufacture.

Gemäß einem Vorschlag der Erfindung weisen die Längsseitenstege schlitzartige Einstecklöcher zum Einstecken der Querseitenstege auf. Auf diese Weise wird es möglich, die Gefache unverlierbar herzustellen, indem nämlich von der bisher üblichen kammartigen Profilierung aller ein Gefache bildenden Teile abgegangen wird. According to a proposal of the invention, the Longitudinal webs slot-like insertion holes for insertion the crossbars on. In this way it becomes possible To create compartments captively, namely by the previously common comb-like profiling of all compartments forming parts is removed.

In Weiterbildung der Erfindung wird vorgeschlagen, daß an den den Querseitenstegen zwischen einander gegenüberliegenden Rändern einander gegenüberliegende Einstecknuten ausgebildet sind, zwischen denen ein Einstecksteg einer Länge zum Einstecken in ein Einsteckloch der Längsseitenstege ausgebildet ist.In a development of the invention it is proposed that the the transverse side webs between opposite one another Edges lying opposite one another are formed are, between which an insertion web of a length for Insert into an insertion hole in the long side bars is trained.

Die Gefache aus den Längsseitenstegen und Querseitenstegen lassen sich somit durch einfaches Zusammendrücken oder Spreizen der Teile zusammensetzen, indem ein Teil durch das andere hindurchgesteckt wird.The compartments from the long side bars and short side bars can thus be simply squeezed or Spread the parts together by passing a part through the other is put through.

Hierbei sind die Längsseitenstege und Querseitenstege aus Schaumstoff selbsttragend gefertigt, so daß stets ein stabiles Gefache entsteht. Je nach gewählter Eigenschaft, Dicke und Rohgewicht des Schaumstoffes werden die gewünschten stoßabsorbierenden Eigenschaften erreicht.Here, the long side bars and transverse side bars are off Foam made self-supporting, so that always a stable Divisions arise. Depending on the selected property, thickness and Raw weight of the foam will be the desired shock-absorbing properties achieved.

Darüber hinaus hat das erfindungsgemäße Gefache den Vorteil, daß die Gefachabteile auch den Abmessungen der Produkte entsprechend zumindest bereichsweise hergestellt werden können, so daß entsprechende darin zu transportierende Produkte beim Einsetzen in die Abteile der Gefache leicht elastisch einklemmbar sind und nicht klappern.In addition, the compartment according to the invention has the advantage that the compartment compartments also the dimensions of the products be produced accordingly at least in some areas can, so that corresponding to be transported Products when inserted into the compartments of the compartments easily can be clamped elastically and do not rattle.

Die Größe der Abteile eines Gefaches sowie die Höhe sind beliebig herstellbar. Es können sowohl Gefache mit quadratischem als auch mit rechteckigen Grundrissen als auch mit Romben oder dergleichen hergestellt werden.The size of the compartments of a compartment as well as the height are can be made as required. Both compartments can be used square as well as rectangular floor plans as well be made with Romben or the like.

Die erfindungsgemäßen Gefache können aus Schaumstoffbahnen in einfacher Weise durch Ausstanzen oder Ausschneiden zum Beispiel mittels Wasserstrahltechnik in den jeweils gewünschten Abmessungen und den zu transportierenden Produkten angepaßt hergestellt werden.The compartments according to the invention can be made from foam sheets simply by punching out or cutting out Example using water jet technology in each desired dimensions and the products to be transported be made to fit.

Für die Ausbildung der Gefache wird des weiteren vorgeschlagen, daß die Einstecklöcher eine Länge aufweisen, die gleich groß oder geringfügig größer als die Länge der Einsteckstege der Querseitenstege bemessen ist.For the formation of the compartments is further suggested that the insertion holes have a length which are the same size or slightly larger than the length of the Insertion bars of the transverse side bars is dimensioned.

Es ist bevorzugt, daß die Längsseitenstege und die Querseitenstege eine gleiche Wanddicke aufweisen. Des weiteren ist es bevorzugt, daß alle Längsseitenstege untereinander und alle Querseitenstege untereinander gleich ausgebildet sind. Hiermit können Gefache mit einem quadratischen oder rechteckigen Grundriß der Abteile in einfacher Weise hergestellt werden.It is preferred that the longitudinal side webs and the Transverse side webs have the same wall thickness. Furthermore it is preferred that all longitudinal side webs with each other and all transverse side webs are designed identically to one another. This allows compartments with a square or rectangular layout of the compartments in a simple manner getting produced.

Darüber hinaus wird vorgeschlagen, die Breite der Einstecklöcher der Längsseitenstege gleich der Dicke der Querseitenstege auszubilden und die Breite der Einstecknuten der Querseitenstege gleich der Dicke des Längsseitensteges. Auf diese Weise wird ein leichtes Einstecken der zu dem Gefache miteinander zu verbindenden Teile erreicht, wobei durch die Elastizität des eingesetzten Schaumstoffes eine leichte Klemmwirkung im zusammengesteckten Zustand der Längsseitenstege und Querseitenstege erreichbar ist.It also suggests the breadth of the Insertion holes of the long side webs equal to the thickness of the Form transverse side webs and the width of the insertion grooves the transverse side webs equal to the thickness of the long side web. In this way, an easy insertion of the to Partitions to be joined together parts, whereby due to the elasticity of the foam used slight clamping effect when plugged together Longitudinal webs and transverse side webs can be reached.

Üblicherweise weisen bei Gefachen die Längsseitenstege und die Querseitenstege gleiche Höhe auf. Es ist aber auch möglich, hier durch entsprechende Anordnung der Einsteckschlitze Längsseitenstege und Querseitenstege mit unterschiedlichen Höhen miteinander zu einem Gefache zu verbinden, sofern dies erwünscht ist.The compartments usually have the long side webs and the Crossbars of the same height. But it is also possible here by appropriate arrangement of the insertion slots Long side bars and transverse side bars with different Combine heights to form a compartment, provided this is desired.

Als Schaumstoff für die erfindungsgemäßen Mehrwegegefache werden Schaumstoffe mit überwiegend geschlossenzelliger Struktur bevorzugt, die zugleich wasserabweisende Eigenschaften aufweisen. Darüber hinaus ist es möglich, den Schaumstoff zusätzlich mit einem wasserabweisenden Überzug auszurüsten.

Die Gefache werden somit aus zwei unterschiedlich gestalteten Teilen hergestellt, die es ermöglichen, die Gefache unverlierbar zu verbinden, d.h. die Gefache können nicht von allein, zum Beispiel beim Transport durch Rüttelbewegungen oder durch falsches Anfassen, auseinandergezogen werden, wie das bei aus kammartig ausgebildeten Gefachteilen aus Pappe oder Holz bisher möglich war.1a and 2a are the two parts from which the Compartments are shown in plan view, namely the long side web 10 and transverse side web 20 Compartments are thus made up of two different designs Parts made that allow the compartments to be captively connected, i.e. the compartments can not by alone, for example during transportation by shaking movements or pulled apart by wrong handling, like that in comb-like compartments made of cardboard or wood was previously possible.

Erfindungsgemäß sind die Gefachteile, nämlich die Längsseitenstege 10 und die Querseitenstege 20 aus einem elastischen biegsamen Schaumstoff hergestellt, beispielsweise aus Schaumstoffbahnen entsprechender Dicke durch Ausstanzen oder Ausschneiden, beispielsweise mittels der Wasserstrahltechnik hergestellt.According to the invention, the compartments, namely the Longitudinal webs 10 and the transverse side webs 20 from one elastic pliable foam made, for example from foam sheets of appropriate thickness by punching out or cut, for example by means of the Water jet technology manufactured.

Die Längsseitenstege 10 gemäß Fig. 1a weisen hierbei schlitzartige Einstecklöcher 11 auf, die quer zur Längserstreckung des Längsseitensteges gleichmäßig voneinander beabstandet mit dem Abstand a angeordnet sind, beispielsweise auch symmetrisch zur Längsachse des Längsseitensteges. Die schlitzartigen Einstecklöcher 11 enden jeweils mit einem Abstand a1 bzw. a2 von den Längsseitenrändern des Längsseitensteges 10, wobei diese Abstände a1 und a2 gleich oder unterschiedlich sein können. Die Einsteckschlitze 11 selbst weisen eine Länge S1 auf und eine Breite b1. Die schlitzartigen Einstecklöcher 11 dienen dem Einstecken und Durchstecken der Querseitenstege 20 gemäß Fig. 2a zum Ausbilden des Gefaches.The longitudinal side webs 10 according to FIG. 1a have here slot-like insertion holes 11 which are transverse to Longitudinal extension of the longitudinal web evenly from each other are spaced apart with the distance a, for example also symmetrical to the longitudinal axis of the longitudinal web. The slot-like insertion holes 11 each end with a Distance a1 or a2 from the long edges of the Longitudinal web 10, these distances a1 and a2 being equal or can be different. The insertion slots 11 themselves have a length S1 and a width b1. The slot-like insertion holes 11 are used for insertion and Pushing through the transverse side webs 20 according to FIG. 2a for Form the compartment.

Die Querseitenstege 20 sind mit quer zur Längserstreckung des Querseitensteges 20 von den Längsseitenrändern des Querseitensteges ausgehenden einander gegenüberliegenden und somit paarweise angeordneten Einstecknuten 21, 22 ausgebildet, wobei die Paare von Einstecknuten 21, 22 in gleichmäßigem Abstand c voneinander über die Länge des Querseitensteges 20 angeordnet sind. Zwischen den beiden Einstecknuten 21, 22 verbleibt ein sogenannter Einstecksteg 23 mit einer Länge S2. Die Einstecknuten 21, 22 weisen eine Einstecktiefe a3 bzw. a4 bei einer Breite b2 auf.The transverse side webs 20 are transverse to the longitudinal extension of the Cross-side web 20 from the longitudinal side edges of the Transverse sidebar and opposite insert grooves 21, 22 arranged in pairs, the pairs of insertion grooves 21, 22 in uniform Distance c from one another over the length of the transverse side web 20 are arranged. Between the two insertion grooves 21, 22 A so-called insertion web 23 with a length S2 remains. The insertion grooves 21, 22 have an insertion depth a3 or a4 at a width b2.

In der Fig. 5 ist schematisch dargestellt, wie der Querseitensteg 20 aus dem elastischen biegsamen Schaumstoff durch Zusammendrücken in Pfeilrichtung P3, P4 in seiner Höhe h2 verringert wird und in Pfeilrichtung P5 durch den Einsteckschlitz 11 des Längsseitensteges 10 hindurchgesteckt wird, bis ein Einstecksteg 23 sich in dem schlitzartigen Einsteckloch 11 befindet und die Einstecknuten 21 bzw. 22 die verbleibende Stege 12, 13 zu beiden Seiten des Einsteckloches 11 des Längsseitensteges 10 umfassen.5 shows schematically how the Transverse web 20 made of the elastic, flexible foam by compressing in the direction of the arrow P3, P4 in height h2 is reduced and in the direction of arrow P5 by the Insert slot 11 of the longitudinal side web 10 through until an insertion web 23 is in the slot-like The insertion hole 11 is located and the insertion grooves 21 and 22, respectively remaining webs 12, 13 on both sides of the insertion hole 11 of the longitudinal web 10 include.

Ein fertiggestecktes Gefache ist in der Fig. 3a in Draufsicht und der Fig. 3b in der Seitenansicht gemäß Pfeilrichtung A in Fig. 3a dargestellt. Das Gefache 1 gemäß Fig. 3a, 3b ist beispielsweise aus vier Längsseitenstegen 10 und vier Querseitenstegen 20 zusammengesetzt, wobei diese jeweils gleiche Höhe h1 und h2 sowie gleiche Abstände a der Einsteckschlitze 11 voneinander zu dem Abstand c der paarweisen Einstecknuten 21, 22 zueinander aufweisen, wodurch quadratische Abteile 100 in dem Gefache 1 geschaffen werden.A fully assembled compartment is in plan view in FIG. 3a and FIG. 3b in a side view according to arrow direction A in Fig. 3a shown. The compartment 1 according to FIGS. 3a, 3b is for example, from four long side webs 10 and four Cross side webs 20 composed, each of these same height h1 and h2 and equal distances a der Insert slots 11 from each other to the distance c have pairs of insertion grooves 21, 22 to each other, whereby square compartments 100 can be created in the compartment 1.

Durch die Ausbildung der Einsteckschlitze einerseits und der Einstecknuten andererseits gelingt es, das Gefache verliersicher zusammenzustecken, so daß sich nicht von alleine lösen kann, sondern erheblicher gezielter Kräfte bedarf einschließlich Verformungen, um es wieder zu lösen.By forming the insertion slots on the one hand and the Insertion grooves on the other hand succeed the compartment to be captive so that it does not go away on its own can solve, but requires considerable targeted forces including deformations to release it again.

In der Fig. 4a ist ersichtlich, wie das Gefache gemäß Fig. 3a beispielsweise in Pfeilrichtung P1, P2 zusammengeschoben und so als Leergut mit wenig Platzbedarf transportiert werden kann, ohne es zu beschädigen. In der Fig. 4b ist die schematisierte Draufsicht auf das zusammengeschobene Gefache nach Fig. 4a ersichtlich. 4a shows how the compartment according to FIG. 3a for example, pushed together in the direction of arrow P1, P2 and can be transported as empties with little space can without damaging it. 4b is the schematic top view of the collapsed compartments 4a can be seen.
