Abstract

The foldable particle-foam container has a bottom element (10), four side walls (11,12,13,14) and a rigid frame (15) arranged at the edges of the side walls. The bottom element, side walls and rigid frame are made of expanded polypropylene. The former and latter side walls are connected to the rigid frame through a joint. An independent claim is also included for a set with two inserts.

Description

The invention relates to a folding particle foam container, in particular for the transport, storage and / or the provision of industrial products, foods or other goods according to claim 1.

Folding particle foam containers are basically known in the art. For example, the EP 1 868 918 B1 describes a thermally insulating transport box, which consists of a bottom part, two longitudinal side parts, two transverse side parts and a cover part. Both the longitudinal side parts, as well as the transverse side parts are pivotally mounted on the bottom part about each parallel to the bottom part extending pivot axes.

The transport box according to EP 1 868 918 B1 Although allows a relatively good insulation for food and the like, the stability and in particular the flexibility of the transport box in their application is perceived as unsatisfactory.

The invention has for its object to show a folding particle foam container, which is characterized by a comparatively high stability and preferably by a high flexibility in the application. This object is achieved by a folding particle foam container according to claim 1.

In particular, the object is achieved by a hinged particle foam container, preferably for transporting, storing and providing foodstuffs and the like, having a bottom element, a first, second, third and fourth side wall and a rigid frame which is arranged on an edge of the side walls, wherein the bottom element and the side walls, possibly also the frame, at least partially made of particle foam, in particular expanded polypropylene (EPP) are made, wherein the first and second side wall are hinged to the rigid frame via a hinge and against the bottom element (within a predetermined Angular region) are freely pivotable, wherein the third and fourth side wall are foldable and are connected to the frame and the bottom element.

An essential idea of the invention is that all side walls are connected to the rigid frame and remain connected in the folded and unfolded state with this. In contrast, in the prior art, namely the EP 1 868 918 B1 , All longitudinal and transverse side parts hinged to the bottom part and freely pivoted at its edge facing away from the bottom part. By contrast, a rigid frame is realized by the present invention, which increases the stability of the folding particle foam container. In particular, not necessarily a cover element, as in accordance with EP 1 868 918 B1 necessary to ensure sufficient stability. As a result, a folding particle foam container is also fundamentally simplified in construction, which should not preclude the possibility of possibly providing a cover element. Especially for the case that a cover element is provided, the folding particle foam container is particularly advantageous. Thus, it is not necessary, in particular by the formation of the rigid frame, to remove the lid before folding. The lid can remain folded on the rigid frame.

Furthermore, the folding particle foam container is also particularly well suited for use in automated systems, since the handling can be done comparatively easily. Furthermore, compared to the prior art, a greater height of the side walls (with sufficient stability of the particle foam container) can be realized.

More preferably, the collapsible particulate foam container is used (and is so adapted) for the transport, storage and provision of industrial products, foodstuffs and other goods. For example, the foldable Particle foam containers may be used to transport, store and / or provide machine parts and the like.

In a preferred embodiment, the folding particle foam container is stackable in a folded and / or unfolded state. This simplifies the handling of the folding particle foam container. In this context, "stackable" should in particular mean that the foldable particle foam container is designed such that it can be arranged (in the folded in and / or unfolded state) over another foldable particle foam container in such a way that the two particle foam containers arranged one above the other are opposite to a predetermined one the side acting force are determined (in this consideration, frictional forces should not be considered).

In a specific embodiment, the foldable particle foam container or a single foldable particle foam container, which is located in a stack of folding particle foam containers, can also be folded in this state; d. H. the folding particle foam container does not necessarily have to be removed from the stack (for example, if further particle foam containers are arranged above and / or below the particle foam container). Overall, this considerably simplifies the handling of the particle foam container. Furthermore, an automation of the handling of the particle foam container, in particular the automatic assembly and / or unfolding of the particle foam container in a simple manner possible. The particle foam container can be designed such that in a plurality of stacked particle foam containers at least one particle foam container (or a first plurality) in the folded state and at least one container (or a second plurality) may be present in the unfolded state (for example, alternating).

Preferably, the bottom element on a bottom side on, in particular circumferential or interrupted, fold. As a result, the folding particle foam container can be set particularly easily in relation to another folding particle foam container in superimposed state. A circumferential fold has the advantage that in this case a comparatively good stability is ensured. An interrupted fold has the further advantage that an outflow of liquid between two stacked particle foam containers arranged one above the other is improved.

In a preferred embodiment, the rigid edge of the folding particle foam container is formed corresponding to the fold. This also improves handling, in particular stackability of the folding particle foam container.

Preferably, the edge protrudes (also) in the folded state of the folding particle foam container away from the bottom element. As a result, the edge, even in the folded state, can engage in a recess of a further folding particle foam container, which further improves the handling, in particular the stackability, of the folding particle foam container.

Between the frame and the first and / or the second and / or the third and / or the fourth side wall and / or between the bottom element and the third and / or the fourth side wall and / or between a first side wall portion and a second wall portion and the third and / or the fourth side wall may be formed a hinge.

Preferably, at least one hinge, more preferably all hinges are arranged within the folding particle foam container. The fact that the hinges thus do not protrude, the robustness and in particular the handling of the folding particle foam container is further improved.

Preferably, the hinges comprise rods and / or tubes, in particular of plastic, and / or film hinges. Particularly preferred is the connection between the frame and the first and / or second and / or third and / or fourth side wall via rods or pipes (made of plastic) form. As a result, the frame part is further reinforced, which improves the stability of the folding particle foam container. In general, the frame can also be reinforced, for example foamed with respect to the bottom element and / or the side walls of higher density. Film hinges are particularly preferably provided between the first and second side wall portion of the third and / or fourth side wall. These film hinges can for example be molded or provided via a subsequently applied film. As a result, the effort, in particular cost in the production of the folding particle foam container is reduced.

In preferred embodiments, at least one hinge has a receptacle with a continuous cylinder jacket surface, for example to receive a rod or a tube. The axis (for example rod or tube) can be foamed. As a result, the stability of the hinge and thus the particle foam container is further improved. In particular, the reliability of the connection is improved by simple means. It is possible to position the corresponding axis already during the production process (before the foaming of the particle foam) in such a way that the axis is foamed by the particle foam during the formation of the particle foam. As a result, a reliable and positive connection is realized in a simple manner. Alternatively, the continuous or circumferential cylinder jacket surface in the foaming process can also be realized by using appropriate slides.

The axis (for example rod or tube) may be made (at least in sections) of the same material as other components of the folding particle foam container, in particular as the side walls. Further preferably, at least one axis (possibly all axes) of the same material as all other components of the folding foam container. For example, the particle foam container (essentially) made of expanded polypropylene (EPP) and the axis of (unexpanded) polypropylene (PP). With such a design, the recyclability of the particle foam container is improved. This reduces the overall costs associated with the particulate foam container.

In an alternative embodiment, the axis (in particular the tube) may also be made of aluminum or an aluminum alloy. As a result, a high stability (rigidity) can be ensured in a structurally simple manner. Overall, the provision of the axes (for example rod or tube) not only allows a simple pivoting of the corresponding side walls, but also improves the stability of the particle foam container, for example compared to ball joints. In a synergistic way, several functions are thus taken into account with a single component, which further reduces the production costs.

Preferably, the bottom element has at least one rib. As a result, the stability of the folding particle foam container can be improved. For example, it may be provided a rib along an edge of the Floor element, however, at a predetermined distance (circumferential or interrupted) runs and thus defines the (circumferential or interrupted) fold. It can also be arranged a plurality of parallel ribs. The ribs may in particular be arranged in a cross pattern.

Preferably, a recess is formed on an upper side of the bottom element in order to receive the first and / or second side wall, in particular latching. The depression can be an undercut. In particular, the latching can be carried out via an additional element (injection-molded element). In any case, the hinged particle foam container is further stabilized.

Furthermore, a bottom elevation may be formed on the upper side of the floor element, which can be brought into engagement with a corresponding Seitenwandausnehmung, in particular (outwardly open) side wall pocket. Alternatively or additionally, a bottom recess, in particular (inwardly opened) bottom pocket may be provided on the upper side of the bottom element, in order to receive a Seitenwanderhöhung. Bottom elevation and sidewall recess preferably define a dovetail joint. Also Seitenwanderhöhung and bottom pocket can define a dovetail connection. A dovetail connection may in particular be understood to mean a positive connection similar to a tongue and groove connection, in which the shape of the "spring" remotely reminds of the forked shape of the tail of a swallow. The "spring" (increase) widens, for example, with increasing height. The recess widens in particular with increasing depth. The (oblique) flanks of the increase or recess act reinforcing the force according to the principle of a wedge. By providing such a dovetail joint tensile forces (for example, between the bottom and first and / or second side wall) can be easily resisted. In a constructive manner, use is made in a simple manner of the fact that the first and second side wall are designed to be pivotable and thus particularly simple elevations can be introduced into corresponding recesses.

By providing a side wall pocket and / or bottom pocket not only tensile forces (to a certain extent) are resisted, but also prevented in a simple way that the side wall can fold outwards. Is the sidewall pocket open to the outside or the bottom pocket to the inside, can a corresponding increase in the floor or the side wall can be easily introduced. By a pocket bottom further pivoting of the side wall is reliably prevented. If the bottom pocket at the same time still widening in cross section towards the bottom, a reliable resistance to tensile forces can be realized at the same time. Accordingly, a possibly provided side wall pocket can be opened to the outside and have a cross-section which tapers (in the unfolded state) towards the bottom.

In a concrete embodiment, the bottom element is formed trough-shaped and additionally or alternatively has a receiving contour. Regardless of its design, the bottom member may preferably be releasably formed from the remaining components of the particulate foam container, for example by allowing a rod of a hinge to be removed (the rod releasably connecting the bottom member to the remaining components of the particulate foam container).

The advantage of a trough-shaped design of the bottom element or a design of the bottom element with a receiving contour is that male industrial products can be kept very safe. The receiving contour may, for example, have a round, elliptical and / or quadrangular (polygonal) cross section. It can also be provided several receiving contours. In particular, when the bottom element is detachably formed, the initially provided bottom element can be replaced by a second (differing from the first) bottom element, which improves the flexibility and possible applications of the folding particle foam container.

In a preferred first alternative, the bottom element is formed in one piece. Such a floor element is easy to manufacture and robust.

Alternatively, the bottom element may also have an outer wall and an insert, which preferably has a receiving contour. In particular, when the insert is detachably formed by the outer wall, an extremely flexible folding foam container is realized. It is particularly preferred if the outer wall of particle foam, in particular made of expanded polypropylene, is made, and the insert of a (in particular impermeable) material, which is harder and possibly less elastic than the particle foam of the outer wall. Such a two-part design becomes a reliable one Particle foam container realized in which the outer wall of particle foam due to its damping properties can protect the transported or stored object from damage and the insert possibly ensures a liquid-tight recording and the remaining components of the folding particle foam container, in particular the outer wall, from damage and contamination the object to be photographed, protects.

A height of the bottom element may have at least 5%, preferably at least 10%, more preferably at least 20%, even more preferably at least 30% of a height of the folding particle foam container in the unfolded state.

The bottom element may be rigid, in the sense that its shape is unchanged in the unfolded and folded state of the folding particle foam container.

At least one of the side walls, preferably the first and / or second side wall, may have a handle, in particular a grip recess. Preferably, the handle, in particular the recessed grip (completely) in an upper half, preferably in an upper third, even more preferably in an upper quarter of the corresponding side wall (in the unfolded state) is arranged. Instead of a recessed grip can also be provided a Grifferhöhung.

The arrangement of the handle in an upper region of the particle foam container at the same time the wearing comfort is improved and the stability of the particle foam container (especially in a formation in the form of a trough) only slightly affected.

At least one of the side walls may comprise at least one identification receptacle (eg for receiving a label) and / or an identification. The identification recording or marking can be arranged (completely) in an upper half, preferably in an upper third, more preferably in an upper quarter of the corresponding side wall (in the unfolded state of the particle foam container). By means of such identification recording, identification of the particle foam container or of a content thereof can be carried out in a simple manner. In a special preferred embodiment, the identification receptacle is provided on an outer wall of the rigid frame. As a result, a recorded marking is recognizable even in the folded state of the particle foam container. This facilitates the handling of the particle foam container.

The abovementioned object is achieved independently by a set comprising a particle foam container, in particular of the type described above, with at least one first floor element and one second floor element with a height and / or receiving contour deviating from the first floor element. By means of such a system, different objects can be accommodated in the folding particle foam container with comparatively low costs or reduced material expenditure, wherein in particular the foldable particle foam container can be adapted to the object to be picked up.

Alternatively, the above object is achieved by a set, comprising a particle foam container of the type described above and at least two deposits, which differ from each other in terms of their height and / or recording contour of each other.

Furthermore, a bottom element for a folding particle foam container, in particular of the type described above, is proposed, wherein the bottom element preferably has at least one hinge device, and wherein the bottom element is trough-shaped and / or has a receiving contour. Furthermore, a set for a folding particle foam container, in particular of the type described above, independently proposed comprising a, in particular trough-shaped, outer wall of a bottom element, at least a first insert and a second insert, which differ from each other in terms of their height and / or a receiving contour.

Further embodiments emerge from the subclaims.

The invention will also be described in terms of further features and advantages based on embodiments, which are explained in more detail with reference to the drawings.

In the following description, the same reference numerals are used for identical and equivalent parts.

Fig. 1 shows a schematic oblique view of a first embodiment of the folding particle foam container. The hinged particle foam container comprises a bottom element 10, a first side wall 11, a second side wall 12 opposite the first side wall, a third side wall 13, a fourth side wall 14 opposite the third side wall 13 and a frame 15 bordering the side walls 11 to 14, which (in FIG unfolded state) the bottom element 10 is opposite.

The first and second side wall are mirror images of each other. The third and fourth side wall are also mirrored to each other. In this respect, the following statements apply to the first and third side wall also respectively corresponding to the second and fourth side wall. In general, however, this should not be excluded that the first and second side wall are formed differently (as well as third and fourth side wall).

The first side wall 11 has on the outside a recessed grip 16. This improves the handling of the folding particle foam container. The recessed grips 16 are (approximately) mounted in the center of the side walls 11, 12.

The first side wall 11 is hinged via a frame hinge 17 to the frame 15 (see also Fig. 2 ). The frame hinge 17 comprises a plastic rod 18. Alternatively, instead of the plastic rod, a plastic tube may be provided.

A fitting in the unfolded state at the bottom end 19 of the first side wall (see also Fig. 5 ) is against the bottom element 10 freely (inwardly) pivotable.

Guides for the plastic rod 18 are inserted within the frame 15 and a frame-side end 20 of the first side wall 11, for example by a core pull in a production tool.

The bottom end 19 has a recess 21, are arranged within the two elevations 22, which cooperate with three introduced in the bottom element 10 elevations 23, so that a comparatively stable fixing of the first side wall 11 relative to the bottom element 10 is achieved in the unfolded state. This stability can be further improved by a (not recognizable) undercut in the bottom element 10.

The third side wall 13 (see Fig. 1 and 2 ) is attached to the frame 15 via a frame hinge 24 (see FIGS. 5 and 6 ) hinged. The frame hinge 24 comprises a plastic rod 25 (alternatively plastic tube) which extends in corresponding receptacles (not shown in the figures) of the frame 15 and the third side wall 13.

Overall, the stability of the folding particle foam container, in particular in the region of the frame 15, is markedly improved by the plastic rods 18 and 25. Also, the frame 15 itself reinforced, for example, be foamed with higher density.

The third side wall 13 is above a bottom hinge 26 (see FIGS. 5 and 6 ) is articulated with a corresponding plastic rod 27 on the bottom element 10. The plastic rod 27 is accommodated in (not recognizable) receptacles of the third side wall or the bottom element 10. The third side wall 13 consists of a first side wall portion 28 and a second side wall portion 29 (see Fig. 2 ), which are separated by a folding hinge 30. The folding hinge 30 is preferably designed as a film hinge. This can either be molded or provided via a subsequently applied film.

In particular Fig. 3 can be removed, the frame 15 is formed circumferentially and thus defines the side walls 11 to 14 in a stable manner.

Fig. 4 shows the folding particle foam container in a view from below. To see is a circumferential fold 31 (see also Fig. 2 . 5 and 6 ). This fold 31 corresponds to a running on an edge 32 of the bottom member 10 gradation against a circumferential increase 33 (see Fig. 4 and 6 ). The elevation 33 consists of four ribs 34 running along the edge 32. Another rib 35 runs in the center of an underside 36 of the bottom element 10 parallel to the third or fourth side wall 13, 14. A further rib 37 runs in the center of the underside 36 of the bottom element 10 parallel to the first and second side wall 11, 12. Overall, this results in a cross rib structure. In Fig. 4 are still in the range of the third and fourth side wall 13, 14 each three recesses 38 can be seen, resulting from the production of the bottom hinge 26 (deep-drawing process).

The collapsible particulate foam container may preferably be reduced by folding in height to 10% to 50% (about 30%). The wall thickness of the folding particle foam container is preferably in the range of 20 mm to 40 mm, more preferably 25 mm to 30 mm. This allows a comparatively good insulation can be achieved. The folding particle foam container can be stacked both folded in and out.

The hinged particle foam container may have a lid (not in the Fig. 1 to 6 shown). Preferably, the hinged particle foam container is also stackable with a lid.

Due to the concrete design of the hinges on plastic rods or tubes of the hinged particle foam container is relatively well reinforced against deformation or damage.

The hinges do not protrude outwards and are thus integrally inserted in the folding particle foam container or the side walls 11 to 14, the bottom element 10 and the frame 15.

A diameter of the hinge rods or tubes or the corresponding receptacles for the hinge rods is / are preferably in the range of 5 mm to 15 mm (in particular about 10 mm).

The third and fourth side walls 13, 14 fall (centrally) over the corresponding hinge inwards.

As a particle foam in particular expanded polypropylene (EPP) or polyolefin or polystyrene (EPS) comes into question.

Fig. 7 shows a second embodiment of the particle foam container in an oblique view. The second embodiment corresponds to the embodiment according to FIG Fig. 1 (First embodiment) with the following differences. First, on the top side (on the frame 15), a lid 39 is arranged (such may also be optionally provided in the first embodiment). This lid is also preferably (essentially) made of particle foam, but may also be made of ordinary (unexpanded) plastic or other material.

Another difference of the second embodiment from the first is that sidewall fixings 40 are provided. Each sidewall fixture 40 includes an elevation 41 and a recess 42, wherein the recess 42 is preferably configured to receive the elevation 41 (in the collapsed state). In particular, the increase is 41, as in Fig. 8 can be seen arranged on an inner side of one of the side walls 11 to 14 and the recess 42 in the bottom element 12 (in each case, for example, on an edge of the side walls 11 to 14 and the bottom element 10). A preferred geometry of the elevation 41 is in FIG Fig. 8 can be seen, in which the elevation 41 of the side wall 13 is tapered inwardly (in the unfolded state), so that when folding the elevation 41 engages in the corresponding recess 42 formed. In this case, elevations 41 and recess 42 are trapezoidal in cross section. Alternatively (not shown in the figures), it is also conceivable to form an inwardly widening elevation 41 which, when folded, engages in a correspondingly formed recess 42. With such a design, the safety is further increased, as well as tensile forces is particularly resistant. In principle, it is also conceivable to form the increase in cross-section approximately rectangular, further cross-sections are stretchable.

The elevations 23 in the bottom element according to the embodiment according to Fig. 7 are also deviating from the first embodiment. The elevations 23 are (approximately) the same size (the elevations 23 but can also as in Fig. 1 be shown formed).

Overall, the security or robustness against unwanted reopening is again significantly increased by the sidewall fixation 40.

In Fig. 7 . 9 and 10 it can be seen that the lid 39 preferably has a lid frame 43, which facilitates handling of the particle foam container; In particular, a stackability is ensured by the lid frame 43.

Fig. 12 shows a sectional view taken along the line CC Fig. 10 , It can be seen that the lid member 39 opposite the lid frame 43 has a (possibly circumferential) cover fold 44, which improves the stability of the lid and thus the entire particle foam container. Furthermore, it can be seen that a depth of the recessed grip 16 increases upward or away from the bottom element 10. As a result, the handling of the particle foam container is improved.

Fig. 13 shows a second side view of the particle foam container according to Fig. 7 , Fig. 14 shows a cross section along the line BB in Fig. 10 , In particular, in Fig. 14 to recognize that the lid 39 may have lid ribs 45. Overall, a ribbed structure can be analogous Fig. 4 or the ribs 34 and 35 according to Fig. 4 be educated.

In any case, provided ribs improve the stability of the cover 39 and the particle foam container.

Fig. 15 shows a third embodiment of a folding foam storage tank in an oblique view. This third embodiment corresponds (substantially) to the embodiment according to FIG Fig. 1 however, the bottom element 10 is different from the embodiment according to FIG Fig. 1 is trained. The bottom element 10 of the embodiment according to Fig. 15 is trough-shaped in contrast to the planar bottom element 10 of the embodiment according to FIG Fig. 1 , "Trough-shaped" should mean, in particular, that an edge running around a base area is increased in relation to a lowest point of the base area, in particular by at least 5 cm, preferably at least 10 cm, more preferably by at least 20 cm.

In particular, the bottom member 10 according to the embodiment according to Fig. 15 be designed as (rigid) box and in particular have hinge elements 46, in which, for example, a (plastic) rod can be accommodated. In this case, the (plastic) rod can preferably be removed from the hinge elements 46, so that the bottom element 10 can be detached from the remaining components of the folding particle foam container.

The bottom element 10 may be made in one piece (in particular made of particle foam) or consist of several elements.

In the Fig. 16 to 18 is a multi-part (two-part) design of the bottom element 10 can be seen. In the side view according to Fig. 16 the hinge elements 46 are shown as part of a bottom element side wall 47. In the view from above according to Fig. 17 it can be seen that the bottom element 10 according to Fig. 16 constructed in several parts (two parts), namely an outer wall 48 and an insert 49 comprises. The outer wall 48 may preferably be formed as a box (see Fig. 18 which is a section along the line XVIII-XVIII in Fig. 17 shows). The insert 49 has a receiving contour 50, which in the present case has an elliptical cross section and tapers in the direction of the underside of the bottom element 10.

The FIGS. 19 and 20 show an alternative embodiment of a bottom element 10. In contrast to the bottom element according to the FIGS. 16 and 18 Here is a one-piece design given, ie, that there is no separate insert and the receiving contour 50 is also formed by the (one-piece) bottom element in total.

The FIGS. 21 and 22 again show a two-part design of a bottom element 10. The outer wall 48 corresponds to the outer wall according to the embodiment of the FIGS. 16 to 18 , The insert 49 is different from the embodiment according to FIGS. 16 to 18 formed and has two receiving contours 50a and 50b, which is approximately cuboid. Are the (generally differing) deposits in accordance with FIGS. 21 and 22 and the deposit according to the FIGS. 16 to 18 provided side by side, an adaptation to various objects to be picked up is made possible in a simple manner. The same applies to the floor element according to FIGS. 19 and 20 and a floor element analogous FIGS. 21 and 22 (but in one piece) is formed.

In any case, the bottom element 10 and / or the outer wall 48 and / or the insert 49 fastening means, in particular one or more locking devices, in particular to a deposit in the outer wall 48 and / or the bottom element 10 (latching) to secure.

Fig. 23 shows a schematic oblique view of a fourth embodiment of the particle foam container, wherein the first and second side wall are folded upwards (and in Fig. 23 not to be seen). The third and fourth side walls 13, 14 are in the erected state. Overall shows Fig. 23 thus an intermediate state between the unfolded and folded state.

As with the third embodiment, the bottom member 10 of the fourth embodiment is also according to FIG Fig. 23 formed trough-shaped. However, the height is less than the third embodiment and corresponds to (approximately) 20% of an overall height.

In the upper region of the side wall 14 (or more concretely on the frame 15) is an identification recording 51 (see also Fig. 28 ) intended.

The sidewall fixation 40 is in the enlarged embodiment according to Fig. 24 shown in detail. The sidewall fixation 40 can, as in the second embodiment (see. Fig. 8 ) be formed. In particular, the embodiment according to FIG FIGS. 23 and 24 an elevation 41 and a recess 42 on the bottom element 10. The recess 42 is trapezoidal in cross-section and tapers in the direction of an underside of the folding particle foam container. Inwardly, the recess 42 is bounded by a wall 52. As a result, the side wall is fixed in the folded state in a particularly simple manner, in particular when at the opposite end (not in Fig. 24 see) of the side wall 13, a corresponding elevation 41 is formed, which is correspondingly engageable with a corresponding recess 42 in engagement.

In Fig. 25 is a first side view of the embodiment according to Fig. 23 to see. Floor elevations 53 assigned to the first side wall (three floor elevations 53 in the specific case) point upward from an upper edge of the floor element 10. The bottom elevations 53 widen in the direction of the frame 15 and the cover 39, respectively. In the sectional view according to FIG Fig. 26 It can be seen that the second side wall has corresponding bottom elevations 53. Fig. 26 corresponds to a section along the line XXVI-XXVI in Fig. 30 ,

As in Fig. 27 to recognize, has an underside of the embodiment according to Fig. 23 five transverse ribs 37 and seven longitudinal ribs 37 on. The provided with this ribbed rib structure improves the stability of the particle foam container.

In Fig. 29 making a section along the line XXIX-XXIX in Fig. 25 1, it can be seen that the first and second sidewalls 11, 12 are folded up so that distal ends 54 are positioned adjacent the lid 39.

As in FIGS. 30 and 26 To recognize the lid 39 has a raised lid edge 55, so that the collapsible particle foam container, even if the lid is attached, can be stacked in a simple manner.

In general, it is preferred (as in the concrete example of FIGS. 26 and 30 illustrated), that the hinged particle foam container in the unfolded and folded state, each with and without cover, is stackable. As a result, the handling of the particle foam container is simplified.

In Fig. 31 is an oblique view of a section of the side wall 14 and the bottom element 10 of the embodiment according to Fig. 23 to see. A hinge 58 includes an axle 56 and a plurality of receivers 57 (only one of which is in FIG Fig. 31 you can see). The receptacles 57 have continuous (uninterrupted) cylinder jacket surfaces, so that the axle 56 is completely foamed (possibly apart from axle ends).

In Fig. 32 is a section of the bottom element 10 and the first side wall 11 (in the unfolded state) to see. The bottom elevation 53 is in engagement with a side wall recess 59. Both the bottom elevation 53 and the side wall recess 59 widen from one (not in FIG Fig. 32 shown) underside of the folding particle foam container starting.

In the oblique view of a section of the side wall 11 according to Fig. 33 It can be seen that a total of three side wall recesses 59 are formed, between which two Seitenwandhöhungen 60 are arranged. Distal ends 61 of the side elevations 60 are positioned further down (in the unfolded state) as one (when unfolded) lower edge 62 of the sidewall 11. The sideways elevations 60 taper (when unfolded) from bottom to top. To facilitate insertion of the Seitenwanderhöhungen 60, these rounded edges.

In Fig. 34 is a section of the bottom element 10 can be seen. Between the (three) soil elevations 53 two Bodenausnehmungen 62 are formed. The bottom recesses 62 are inwardly (in the direction of arrow 63 in FIG Fig. 34 ), except for a bottom recess end portion 64 which is defined in the direction of the interior of the foam container by a wall 65. The bottom recess end portion 64 is for receiving the supernatant of the distal ends 61 of the side elevations 60 (see FIG Fig. 33 ) formed and provided.

The bottom elevations 53 are engageable with the Seitenwandausnehmungen 59, wherein the Seitenwandausnehmungen 59 are formed as pockets and (in the unfolded state) are bounded by a respective wall 66 inwardly (see Fig. 33 ). By this design can be easily prevented that the side wall 11 (and corresponding side wall 12) works outwards. By the dovetail connections 67 to be recognized in FIG. 67, an extremely reliable fixing of the side wall relative to the floor element can take place. By forming the bottom recess end portions 64, the side wall can be easily fixed or latched to the ground. Overall, an increased stability of the particle foam container is realized by these measures.

As in Fig. 29 can be seen, recessed grips 16 in an upper half of the side walls 11, 12 are arranged (in the unfolded state). As a result, the handling of the particle foam container is simplified and at the same time increases its stability.

It should be noted at this point that all the above-described parts taken alone and in any combination, in particular the details shown in the drawings, are claimed as essential to the invention. Changes are familiar to the person skilled in the art.
