Description

The present invention relates to a collapsible container, in particular as a piece of sports equipment, such as dumbbells and the like. In principle, however, it should not be ruled out that such a folding container is also used outside of the preferred application as travel sports equipment, for example for transporting and/or storing objects and bulk goods.

Such a collapsible container has a collapsible container body which is deformable between a folded, less bulky, stowed condition and an unfolded, more bulky use condition.

Collapsible container bodies are known on the market which are designed as a type of sack. These are deformed from the use state into the stowed state without a predetermined folding pattern, in which they only require a small amount of space compared to the space requirement of the use state. Therefore, these known collapsible container bodies are often rolled or crumpled up, which usually means that the space requirement of the known collapsible container body in the stowed state is larger than necessary.

A folding container body made of plastic film that can be folded according to a defined folding pattern is made of EP 0 146 819 A2 known. Another defined foldable folding container body made of paper is from WO 2010/099902 A1 known.

The folding containers mentioned at the outset can be transported in the stowed state with little space requirement and deformed at the destination into the use state in which the folding container surrounds a container volume into which objects or bulk goods can be filled in order to transport them or to increase the weight of the filled folding container for physical exercise use. Many athletes don't want to do without strength training exercises with defined weights when traveling, where they don't have access to a gym, in order to stay in shape even on vacation.

Particularly in the preferred application as a folding travel container, in particular as travel sports equipment, such as travel weight training equipment, it is desirable to have as little space as possible when stowed in order not to unnecessarily take up any upper limits on luggage volume for travel.

It is therefore the object of the present invention to specify a collapsible container which takes up as little space as possible when stowed away.

The present invention solves this problem by means of a folding container which can be repeatedly deformed from the use state to the stowed state by means of a predetermined folding pattern. Deformation in the opposite sense, namely from the stowed state to the used state, is generally not critical, since the folding container or folding container body initially folded into the deformed state can be unfolded without knowledge of the specific folding pattern.

The collapsible container body of the collapsible container according to the invention is considered and described below in the use state as a reference state, unless expressly stated otherwise. This also applies to claims.

In order to accommodate objects or bulk goods, the folding container body has a container base and a container jacket wall, which proceeds from the container base and is connected to the container base and extends along a circumferential path.

The container shell wall preferably has a polygonal peripheral edge at its end region near the bottom. Accordingly, the container casing wall has a number of wall sections following one another in the circumferential direction of the container casing wall. The container jacket wall thus preferably forms the jacket wall of a polyhedral prism with a polygonal circumference.

Each wall section has at its bottom end area an edge of the polygonal peripheral edge as a bottom wall section edge. Furthermore, each wall section is connected to the container floor in the region of its wall section edge near the floor. It applies to all wall sections that two wall sections that are directly adjacent in the circumferential direction meet each other along a lateral edge, so that each wall section has one lateral edge as the circumferential wall section edge in each of two opposite circumferential directions along the circumferential path. Two wall sections that meet or are adjacent to one another at a peripheral edge in the circumferential direction thus preferably enclose an angle of less than 180° around the peripheral edge. The size of the included angle depends on the number of surfaces of the preferably prismatic container jacket wall or on the number of edges or corners of the polygonal peripheral edge. The sum of all interior angles between successive wall sections along the circumferential path must result in a value which corresponds to the product of the number of corners of the polygonal circumferential edge reduced by 2 and 180°.

In the reference state of the folding container body, each casing edge runs away from the container base, starting from a corner region of the polygonal container base, specifically at a distance from every other casing edge. Preferably, the skirt edges of a collapsible container body are parallel to one another in the ideal datum with no residual folding deformation as is normally observed after unfolding from the stowed condition.

Die Flächenfaltachse eines jeden Wandabschnitts aus der Mehrzahl von Wandabschnitten verläuft dabei ausgehend von einem durch einen ersten Umfangs-Wandabschnittsrand und dem bodennahen Wandabschnittsrand gebildeten Eckbereich in Richtung von dem bodennahen Rand und dem ersten Umfangs-Wandabschnittsrand weg, hin zu dem längs der Umfangsbahn entgegengesetzten zweiten Umfangs-Wandabschnittsrand desselben Wandabschnitts.

In order to deform the collapsible container and thus the collapsible container body from its use state into its stowed state, the following structural measures are implemented on the collapsible container body:

• - each wall section can be folded about a bottom folding axis parallel to its near-bottom wall section edge, preferably coaxial, with its inside facing the interior of the collapsible container body in the direction of the inside of the container bottom,
• All pairs of wall sections that are directly adjacent along a jacket edge in the direction of the circumferential path and are each located on a different side of the jacket edge can be folded with their inner sides towards one another about a jacket folding axis that is parallel to the jacket edge and is preferably coaxial
• - for at least a plurality of wall sections, it applies that each wall section from the plurality of wall sections has two partial wall sections, wherein the partial wall sections of the same wall section fold around a surface folding axis located between two peripheral wall section edges of the wall section in question and parallel to the respective wall section with their edges facing away from the interior of the collapsible container body Outsides are foldable towards each other. The surface folding axis of each wall section from the plurality of wall sections runs, starting from a corner area formed by a first peripheral wall section edge and the wall section edge near the floor, in the direction away from the edge near the floor and the first peripheral wall section edge towards the opposite second circumference along the circumferential path -Wall Section Edge of the same Wall Section.

The foldability of wall sections relative to one another and of partial wall sections relative to one another can be ensured by arranging a folding hinge between the sections which can be folded relative to one another. One or more folding hinges can preferably be formed as a film hinge by the material of the wall section or partial wall section itself. However, it should not be ruled out that the folding hinge is formed from a material different from the material of a wall section connected to the folding hinge.

The folding container body can be deformed repeatedly into a planar stowed state by the specified folding axes, the thickness of which corresponds essentially only to the sum of the wall thicknesses of the wall sections and partial wall sections lying one above the other.

With the specified folding axes, folding of the container bottom can also be avoided in an extremely advantageous manner, which makes it possible to construct it from a stiffer or more rigid material than the container casing wall. For example, the bottom can advantageously be designed as a non-foldable hard shell or plate that is not or only negligibly deformed by objects and bulk material that can be filled into the container volume when the folding container is in use. Such a stiff, above all rigid, container base also has a stabilizing effect on the entire folding container body, since at least the wall section edges near the base of the wall sections of the container jacket wall, which are connected to the container base, can be held by the container base in a dimensionally stable and stable manner relative to the container base.

To facilitate folding while at the same time ensuring the best possible tightness of the folding container body against the escape of bulk material filled into the container volume of the folding container body, the container jacket wall can be made of a plastic film, in particular a plastic film laminate. The plastic film laminate can have at least one layer that is not made of plastic and/or can have at least one layer that is not a film. With such a layer, the plastic film laminate can be stabilized overall and, for example, made more tear-resistant, for example if an additional fabric layer or grid layer is built into the plastic film laminate as a kind of reinforcement.

The container base can be injection molded from plastic, but can also be made from wood or metal or have at least one layer of wood and/or metal and/or a fabric.

The container shell wall can be connected to the container bottom in any suitable manner, for example by separate connecting means such as rivets or screws. Preferably, at least in sections, preferably along the circumferential path, the container casing wall has a plastic that is compatible with an external plastic of the container base, so that the container casing wall can be welded to the container base by means of its external plastic. However, it is also conceivable to use non-compatible plastics or non-compatible materials on the container floor on the one hand and on the container jacket wall on the other hand. Then they could be connected to each other by gluing. The advantage of gluing and/or welding lies in the tightness of the connection that can be achieved, which is particularly advantageous in the bottom area, since this is always reached by bulk material filled into the container volume. As is well known, bulk material can easily escape through the smallest of cracks and gaps due to its ability to flow or pour.

In principle, folding container bodies with any desired polygonal peripheral edge can be deformed into a very flat stowed state in the manner described above. However, folding resistances of different magnitudes may have to be overcome, which are generally higher the more irregular the polygonal peripheral edge is, which is preferably always the same regardless of the distance from the container bottom at which the container casing wall is viewed. A reduction in folding resistance when the folding container body is deformed from the use state to the stowed state can be achieved, for example, by designing the folding container body mirror-symmetrically with respect to at least one plane of mirror symmetry extending in the vertical direction of the folding container body.

In addition or as an alternative, the folding resistances mentioned can also be reduced in that the polygonal peripheral edge is essentially an equilateral polygon or comes very close to an equilateral polygon. It is therefore preferred if the lengths of wall section edges that follow one another along the peripheral path and are close to the ground, of the wall sections that follow one another along the circumferential path, differ by no more than 10%, preferably by no more than 5%, in particular, based on the greatest length of a wall section edge that is close to the ground are preferably of the same length.

With the same consideration of an advantageous, possibly further, reduction in the folding resistances to be overcome during the deformation from the use state to the stowed state, the folding container body can additionally or alternatively be designed in such a way that the enclosed angles between wall sections that follow one another along the circumferential path are related to the largest between wall section edges included angles differ by no more than 10%, preferably differ by no more than 5%, particularly preferably are the same size.

When in use, the wall sections preferably protrude orthogonally from the container bottom or protrude at least at an angle of 80° to 100° from the container bottom.

The above-mentioned preferred design and ensuring the foldability is achieved by the film hinges mentioned, the folding axes generally being reproduced on the folding container body in each of the mentioned operating states of the folding container. It is part of the experience of every user that once surface sections have been folded onto one another, they can be unfolded again, but the fold once performed remains recognizable in the folded surface. Such a permanent recognizability of the fold helps the user to deform the foldable container again from the use state to the stowed state. Therefore, each wall section, which has two partial wall sections that can be folded towards one another about a surface folding axis with their outer sides, preferably has a surface folding edge that runs parallel or preferably coaxially to the surface folding axis assigned to the respective wall section, along which the two partial wall sections meet. The surface fold edge between two partial wall sections essentially corresponds as a boundary between two partial wall sections to the casing edge as a boundary between two wall sections.

Viewed from the outside, the jacket edges on the folding container in the reference state preferably form convex areas and the surface fold edges preferably form concave areas, which is also illustrated by the folding described above during the transition from the use state to the stowed state.

The surface fold edge of the wall section runs in demarcation from a jacket edge and to rule out confusion with a jacket edge, preferably between a first intersection point closer to the container bottom with the first peripheral wall section edge in the direction of a second intersection point further away from the container bottom with the second peripheral edge. Wall Section Edge. As a rule, although this does not necessarily have to be the case, the surface fold edge connects the two peripheral wall section edges, which are each casing edges, of one and the same wall section.

In principle, it can be sufficient if only some of the wall sections have partial wall sections that can be folded about a surface folding axis. This is the case in particular when the container base or also, if present, a container lid has base or lid sections which can be folded relative to one another.

However, as explained above, the container base is preferably as strong as possible and, above all, not foldable. Each wall section of the jacket wall therefore preferably has two partial wall sections which can be folded towards one another about a surface folding axis located between two peripheral wall section edges of the wall section and parallel to the wall section with their outer sides facing away from the interior of the folding container body.

In principle, it can also be considered that the surface folding axes, starting from a corner area on the container bottom, only run at an angle between two peripheral wall section edges. However, for orderly folding and in particular for a stowage condition that is as constant as possible over its extension area, it is preferred if each surface folding axis runs along its course away from the container bottom in the same circumferential direction from the first circumferential wall section edge away to the second circumferential wall section edge. The course of the surface fold axis can usually be recognized by the course of the associated surface fold edge.

In principle, the collapsible container body can be open on its top side opposite the container bottom and/or can have any edge shape on its edge remote from the bottom. In order to provide a defined container volume that can also be recognized by the user, it is preferred that the container wall has a further polygonal peripheral edge at its end region remote from the bottom. The edges of the additional polygonal peripheral edge are preferably rectilinear and more preferably lie in one plane. Therefore, the further polygonal peripheral edge distant from the ground preferably corresponds in its shape to the polygonal peripheral edge of the end region near the ground.

The container base is preferably flat, so that the polygonal peripheral edge of the container casing wall close to the base is also preferably a flat peripheral edge.

It follows from what has been said above that the wall sections mentioned above are particularly preferably rectangular. The folding container body is then preferably a right prism, particularly preferably with the same equilateral, regular polygon as the edge contour in the ideal state of use in a sectional plane orthogonal to the prism axis, regardless of the sectional height.

According to a somewhat more general embodiment, the wall sections can still preferably have peripheral wall section edges parallel to one another in the reference state and wall section edges near and far from the floor parallel to one another, with the surface folding axis going diagonally from a first corner area, formed by a wall section edge near the floor and a first wall section edge to a through the second corner region formed by the wall section edge remote from the floor and the second peripheral wall section edge. Thus, the wall sections can also be configured in the shape of a parallelogram, for example, although this is not preferable to the rectangular wall sections.

The collapsible container body can have a container lid in order in particular to be able to avoid spilling bulk material that has been filled into the collapsible container body. The container lid can be removable from the rest of the collapsible container body or, and this is preferred, can have a container opening with a container closure. The container volume can be made accessible for filling from the outside through the container opening. The container lid is also preferably designed to be stiffer and more rigid than the container jacket wall. In order to provide a folding container body that is as tight as possible, each wall section is preferably connected to the container lid in the region of its wall section edge remote from the bottom. At this connection, too, the folding container preferably forms folding hinges, particularly preferably film hinges, on which each wall section can be folded about a lid folding axis that is parallel, preferably coaxial, to its wall section edge remote from the bottom. This folding of the wall section also takes place with its inside facing the inside of the container lid.

It follows from the above that, according to a particularly preferred embodiment, each folding of the folding container body for a transition between the use state and the stowed state takes place on the container shell wall, while the container bottom and, if present, the container lid always have the same shape, regardless of the operating state of the folding container body.

As a weight training device, it is advantageous if the amount of weight can be changed as extensively as possible by filling the folding container body. This is the case when as little as possible in the filled folding container body Air-filled cavities remain. The collapsible container body is therefore preferably designed to hold liquid and/or granular bulk material, such as water and/or sand.

In principle, the folding of the folding container body described above functions independently of the number of corners and edges of the polygonal peripheral edge close to the ground. Preferably, however, the polygonal peripheral edge near the ground has an even number of corners and edges, since it is then possible for the folding container body, which is particularly preferably configured as a right prism with an equilateral, regular polygon as the basic cross-section, by folding a wall section around its edge area near the ground, one of its corners in the to fold the edge area away from the bottom onto another corner of the container bottom. The other corner is orthogonally spaced from the corner of the edge area near the bottom to the bottom folding axis used in each case.

The distance between two parallel edges of the equilateral, regular polygonal peripheral edge near the bottom is preferably less than or particularly preferably equal to the height of the folding container body and thus preferably the distance from the container bottom to the polygonal peripheral edge distant from the bottom or, if present, to the container lid.

In other words, in the case of a folding container body with a polygonal peripheral edge close to the ground and parallel wall section edges close to the ground of the container jacket wall, the length of a peripheral wall section edge is preferably less than or particularly preferably equal to the product of the length of the wall section edge close to the ground, from which the peripheral wall section edge starts, and the tangent value of half the angle which is enclosed between the wall section with the wall section edge near the ground and a wall section directly adjacent to this wall section.

In the case of a rectangular polygonal peripheral edge near the bottom of the container casing wall, the length of a peripheral wall section edge is preferably less than or particularly preferably equal to the length of the wall section edge near the bottom from which the peripheral wall section edge starts, since two directly adjacent wall sections on a folding container body with a rectangular peripheral edge close to the bottom form a right angle enclose and thus the tangent value of half the angle is "1".

In the case of a square polygonal peripheral edge near the bottom of the container casing wall, the length of each peripheral wall section edge is preferably smaller or particularly preferably equal to the uniform length of the wall section edge close to the bottom.

If a low-level polygonal peripheral edge of the container shell wall is a hexagon, the length of a peripheral wall section edge is preferably less than or more preferably equal to the product of the length of the low-level wall section edge from which the peripheral wall section edge emanates and the tangent value of half the angle which is enclosed between the wall section with the wall section edge near the ground and a wall section immediately adjacent thereto. If the polygonal peripheral edge of the container jacket wall is an equilateral hexagon, the length of each peripheral wall section edge is preferably less than or more preferably equal to the product of the length of the wall section edge near the bottom, from which the peripheral wall section edge starts, and the tangent value halfway between two immediately adjacent wall sections included angle, ie 60 °.

The polygonal peripheral edge of the container casing wall close to the ground is preferably quadrilateral, particularly preferably square, or hexagonal, particularly preferably an equilateral regular hexagon.

In the case of preferred collapsible container bodies in the form of right prisms with an equilateral, regular polygon as the peripheral contour, the container bottom and the container lid can preferably be designed with an identical shape, with the container lid then if the above-described height condition of a distance between two parallel edges of the regular polygon is maintained, is arranged in the stowed state essentially congruent with the container bottom above the container bottom. The container lid or a polygonal peripheral edge remote from the bottom in the case of an open folding container body in the form of a right prism is thus arranged exactly above the container bottom both in the use state and in the stowed state, but further away from the container bottom in the use state. As a result of the folding described above, the container lid or the polygonal peripheral edge remote from the bottom is rotated by that angle when the folding container body is deformed from the use state to the stowed state, which is enclosed between two adjacent edges of the polygonal peripheral edge around the prism axis imaginary to penetrate centrally through the folding container body.

Such an angle is a right angle in a folding cube-shaped container body and is at a hexagonal foldable container body 120°, the preferred foldable container body in each case being designed as a right prism. In the case of a collapsible container body with an equilateral regular octagonal polygonal peripheral edge, the container lid is rotated by 135° when the collapsible container body is folded from the use state to the stowed state.

Since the folding container body can also be used to transport or store objects and bulk goods, the folding container preferably used as travel sports equipment, in particular travel weight training equipment, has a carrying device with which the user can shift the weight of the folding container body in space.

Although the carrying device can be arranged on the collapsible container body and connected to it in any way, for example on the container lid, for reasons which will be explained in detail below, the carrying device is preferably arranged on the collapsible container body in such a way that it spans a section of the collapsible container body. It particularly preferably spans a completely flat surface of the collapsible container body. In order to avoid loading a filling opening for filling the collapsible container body when the collapsible container body is held on the carrying device, the carrying device preferably spans a section of the collapsible container body located within the wall section edge remote from the bottom, such as a container opening bordered by the further polygonal peripheral edge distant from the bottom or, if present , the container lid.

In order to ensure that one hand of the user can operate the carrying device comfortably and safely, the carrying device preferably has a carrying handle designed for hand grip and two connecting straps connecting the carrying handle to the collapsible container body. The connecting straps ensure that the carrying handle is at a sufficient distance from the nearest wall section of the folding container body, so that the user can easily slide his hand between the carrying handle and the wall section in order to completely grasp the carrying handle.

The connecting straps can also be arranged in a foldable or foldable manner on the wall section of the folding container body that carries them, so that the connecting straps do not protrude from the folded folding container body in the stowed state and do not take up unnecessary space.

The connecting straps can be connected to the collapsible container body by plastic welding and/or gluing and/or riveting and/or screwing and the like.

For a configuration of the folding container body that is as space-saving as possible in the stowed state, at least one connecting strap can preferably be releasably connected to the carrying handle. Particularly preferably, both connecting straps can each be releasably connected to the carrying handle.

The connecting lugs are preferably permanently connected to the collapsible container body in a captive manner, ie at least not detachably connected without a tool. The connecting lugs are preferably permanently connected to the collapsible container body as intended, so that they can only be removed from the collapsible container body by destroying the connecting lugs and/or the collapsible container body.

The present invention also relates to a carrying device that can be dismantled, comprising a carrying handle and two connecting straps for connecting the carrying handle to a body. Hereinafter, this body is the folding container body as an example. However, the developments of the carrying device described in the following example of the folding container are also developments of the insulated collapsible carrying device, for which the type of body carried is not important.

In principle, at least one connecting strap that can be detachably connected to the carrying handle is sufficient. However, both connecting lugs are preferably designed in the manner described below for only at least one connecting lug.

To produce the carrying device from the at least one connecting strap that can be releasably connected to the carrying handle and the carrying handle, the connecting strap preferably has a coupling formation and the carrying handle preferably has a counter-coupling formation that can be coupled to the coupling formation.

A formation made up of a coupling formation and a counter-coupling formation has an opening with a first, larger-area push-through section and with a second, smaller-area holding section. The opening with the push-through section and the holding section is delimited by an opening edge. In order to be able to carry the greatest possible weight with the formation having the opening, the opening edge is preferably a closed peripheral opening edge which surrounds both the push-through section and the holding section. The push-through section and the holding section preferably form a common, coherent opening area.

Preferably, for easier handling and for easier visual checking of a correctly established connection between the carrying handle and connecting tab the coupling formation on the opening.

For easy visual recognition of the push-through section and the holding section, the edge of the opening and thus the opening can have a constriction, which is arranged between the push-through section and the holding section.

For a simple connection of the carrying handle to the connecting strap, it is advantageous if the respective other formation made up of the coupling formation and the counter-coupling formation has an insertion formation which can be inserted into the opening along an insertion path.

The insertion formation preferably has a head section and a carrying section adjacent to this along a following axis. In a position ready for the introduction of the insertion formation into the opening, the following axis is inclined by no more than 20° relative to the insertion path, which is preferably a rectilinear insertion axis. Preferably, the following axis is parallel to the insertion path in said insertion-ready position, particularly preferably coaxial to the insertion path.

In order to prevent the insertion formation from unintentionally slipping out of the opening along the following axis and/or along the insertion path, the head section preferably has a larger cross-sectional area in a cross-sectional plane orthogonal to the following axis than the supporting section. Alternatively or additionally, in a cross-sectional plane orthogonal to the following axis, the head section can have a larger dimension orthogonal to the following axis than the supporting section.

Preferably, the head section can be guided through the push-through section along the insertion track to establish a connection with the connecting strap. The support section, but not the push-through section, is designed and/or dimensioned in such a way that it can be accommodated in the holding section because of its shape and dimensions.

For simple but secure locking or latching of the carrying handle on the connecting strap, the constriction of the edge of the opening or of the opening can have a smallest distance which is smaller than the clear width of the holding section.

The constriction of the opening edge can then also have a smallest distance, which is smaller than a characteristic dimension of the support section orthogonal to the following axis of the insertion formation. Since the support section is preferably rotationally symmetrical with the following axis as the axis of rotational symmetry, the characteristic dimension of the support section orthogonal to the following axis is preferably a diameter of the support section, which is preferably cylindrical, including a concave-cylindrical shape with a concave lateral surface, or conical.

In order to ensure that the carrying handle can be latched onto the connecting strap, at least one formation consisting of the edge of the opening in the area of the constriction and the supporting section is preferably designed to be elastic in such a way that the supporting section can be displaced from the push-through section with deformation of the edge of the opening and/or the supporting section in the area of the narrow point into the holding section is.

As a simple, secure and easily visually verifiable connectability of the carrying handle to the connecting strap, it is preferably provided that the carrying handle has the insertion formation and that the at least one connecting strap has the opening. Then the opening can completely push through the connecting strap.

In a further development of the invention, the carrying handle can have a handle section designed and intended for manual gripping, the handle section being arranged in series with the carrying section along the following axis in such a way that the carrying section is arranged between the head section and the handle section.

At least in its end region closest to the carrying section, the grip section preferably has a larger dimension orthogonal to the following axis and/or a cross-sectional area in a cross-sectional plane orthogonal to the following axis than the carrying section. This allows that when the carrying device is ready for operation, a section of the connecting strap enclosing the holding section of the opening can be securely fixed along the following axis physically between the head section and the handle section with a defined play of movement along the following axis. The movement play is preferably less than one millimeter, more preferably less than half a millimeter, in order to keep an unintentional displacement of the connecting strap and thus the weight absorbed in the folding container body as low as possible.

At least one section of the supporting section and the holding section, preferably both sections, preferably has an edge surface that is rotationally symmetrical with respect to an axis that passes through the center of the respective section. As a result, the carrying handle in the connecting strap can be rotated relative to the latter about said axis, which is preferably parallel or coaxial to the following axis. Thus, force repercussions of the oscillating folding container terkörpers be kept low on the person carrying it with the carrying device.

The present invention further relates to the use of a folding container, as described and developed above, as sports equipment, in particular as weight training equipment, particularly preferably as dumbbells.

In 1 an embodiment of a collapsible container according to the invention is generally designated 10 . The folding container 10 comprises a folding container body 12 and a carrying device 14 connected to the folding container body 12 on the upper side of the folding container body 12.

The folding container body 12 in the illustrated embodiment of 1 is a six-sided right prism extending along the virtual prism axis P. The container jacket wall 16 running around the prism axis P along a circumferential path U has six identical rectangles 18 as wall sections 20 _i , with i=1 to 6. The index i counts up along the peripheral path U around the virtual prism axis P incrementally in the counterclockwise direction U1.

The container shell wall 16 covers the container bottom in 1 , which has the shape of an equilateral hexagon. The polygonal, ie hexagonal in the present exemplary embodiment, peripheral edge 22 of the container bottom consequently has six edges 24 _i of equal length, with the counting index i being identical to that of the wall sections.

Each edge 24 _i forms a wall section edge near the floor of the associated wall section 20 _i .

On its upper side, the collapsible container body 12 has a container lid 26 with an opening 30 closed by a screw lid 28 for filling the collapsible container body 12 with bulk material. Since the collapsible container body 12 is a right prism, the peripheral edge 32 of the container lid 26 substantially corresponds to the peripheral edge 22 of the container bottom. In the example shown, edges 33 _i of the peripheral edge 32 of the container lid 26 _of equal length are parallel to the edges 24 _i of the peripheral edge 22 of the container bottom on each wall section 20 i .

Each edge 33 _i forms a wall section edge of the wall section 20 _i that is remote from the floor.

Two wall sections 20 _i that are adjacent in the circumferential direction meet in an ideal state of use free of residual folding deformations along a lateral edge 3 that is parallel to the prism axis P. The lateral edges 34 are in 1 also provided with an index i, which ranges from 1 to 6, with the peripheral edge 34 _i of a wall section 20 i trailing in the counterclockwise _direction U1 - when viewing the container lid 26 along the prism axis P from the outside - the smaller index value and thus the same index value as the wall section having. A wall section 20 _i is therefore delimited in the circumferential direction by the casing edges 34 _i and 34 _i+1 . The jacket edge 34 _i forms a first peripheral wall section edge of the wall section 20 _i and the jacket edge 34 _i+1 forms a second peripheral wall section edge of the wall section 20 _i .

Each wall section 20 _i has two partial wall sections 20a _i and 20b _i which meet along a surface folding edge 36 _i . The surface folding edge 36 _i runs in the associated rech teck wall section 20 _i diagonally from corner to corner, so that the partial wall sections 20a _i and 20b _i each have the same triangular shape.

In order to move the collapsible container body 12 from the in 1 state of use shown in 2 To deform the indicated stowed state, the wall sections 20 _i and the partial wall sections 20a _i and 20b _i can be folded relative to one another and relative to the container bottom and relative to the container lid 26 about defined folding axes in a manner described below.

All folding axes described here are formed by film hinges. The film hinges are in turn formed by the film material of the container jacket wall.

Each wall section 20 _i , in the illustrated embodiment of FIG 1 for the sake of better clarity, exemplified only on the wall section 20 ₁ , can be folded about a bottom folding axis 38 _i , in the case of the wall section 20 ₁ this is the bottom folding axis 38 ₁ . The bottom folding axis 38 _i is parallel, preferably coaxial, to the edge 24 i , ie in the case of the wall section 20 ₁ to the edge 24 ₁ . The ability of the wall section 20 _i to be folded about the bottom folding axis 38 _i is such that the in 1 unillustrated inside of each wall section 20 _i is folded toward the inside of the container bottom directed into the interior volume.

Furthermore, each wall section 20 _i is offset relative to each adjacent wall section 20 _{i -1} and wall section 20 _{i + 1} by a lateral edge 34 _i and 34 _i+1 parallel, preferably coaxial jacket folding axis 40 _i or 40 _i+1 foldable in such a way that the respective inner sides of the adjacent wall sections pointing towards the prism axis P in the state of use are folded towards one another. More specifically, a wall section 20 _i is foldable relative to its clockwise U2 adjacent wall section 20 _i-1 about the jacket fold axis 40 _i and is foldable relative to its counterclockwise U1 adjacent wall section 20 _i+1 about the jacket fold axis 40 _i+1 . Using the example of the wall section 20 ₁ , this can be folded about the jacket folding axis 40 ₁ relative to the wall section 20 ₆ and about the jacket folding axis 40 ₂ relative to the wall section 20 ₂ . The lateral folding axes 40 _i are parallel to the prism axis P in an ideal state of use.

The wall section 20 ₆ is considered to be the wall section 20 _i-1 adjacent to the wall section 20 ₁ clockwise U2 according to the above definition.

Likewise, each wall section 20 _i can be folded relative to the container lid 26 about a lid folding axis 42 _i parallel or preferably coaxial to its edge 33 _i such that the inside of the wall section is folded around the lid folding axis 42 _i to the inside of the container lid 26. This fold is unnecessary if the container lid 26 is not present.

So that the folding described above is possible without excessive stretching of the material of the folding container body 12 or of the container jacket wall 16, each wall section 20 _i of the exemplary embodiment from FIG 1 foldable. More precisely, the two partial wall sections 20a _i and 20b _i of a wall section 20 _i can be folded about a surface folding axis 44 _i of the wall section 20 _i parallel to the surface folding edge 36 _i and preferably coaxial in such a way that sections of the outer sides of the partial wall sections 20a _i and 20b _{i of} one and the same wall section 20 _i come to lie on top of each other.

With this folding, the folding container body 12 can be folded into a flat stowed state, the thickness of which essentially corresponds only to the thickness of the essentially flat wall section areas lying one on top of the other.

This fold can be achieved with any folding container body in the form of a right prism, the right prism preferably having an equilateral polygon with an even number of corners as the base.

In 2 the stowed state of the folding container body 12 is shown as an example and in part in order to explain the folding again. In 2 For the sake of clarity, only the wall sections 20 ₁ and 20 ₂ are shown in their folded condition, which they have when the collapsible container body 12 is in the stowed condition.

In the representation of 2 lines and edges visible after folding are drawn solid. Hidden lines and edges of the wall section 20 ₁ are shown in dashed lines. Hidden lines of the wall section 20 ₂ are shown in dotted form, with the dot spacing increasing as more layers of wall material are located over the relevant line or edge.

In the preferred embodiment of 1 the dimensions of the wall sections 20 _i are selected in such a way that the edge length of a casing edge 34 _i and thus the height of the folding container body 12 when in use corresponds to the distance between parallel edges 24 _i of the peripheral edge 22 on the container bottom or between parallel edges 33 _i of the peripheral edge 32 on the Container lid 26 ent speaks. The length of the surface fold edges 34 i running diagonally through the wall section 20 _i thus corresponds _to the diameter of the hexagonal container bottom or the hexagonal container lid 26.

Due to this special dimension, the container lid 26 comes to lie congruently with the container bottom over the container bottom in the stowed state. Therefore, the collapsible container body 12 occupies the same floor area in the storage state as in the use state. Only the height of the collapsible container body 12 changes when in use versus when stowed.

However, as a result of the folding, the container lid 26 undergoes a rotation of 120° about the prism axis P relative to the container bottom. Therefore, in the stowed condition, edge 33 ₁ will overlie edge 24 ₃ and edge 33 ₂ will overlie edge 24 ₄ . In use, a hexagonal prismatic collapsible container body 12 has edge 33 _i overlying edge 24 _i . In the stowed state, on the other hand, the edge 33 _i lies above the edge 24 _i+2 .

2 shows the folding container body 12 using the example of a right prism with a uniform hexagonal base. However, the folding principle explained also works with a cube-shaped folding container body 12 or with a straight prismatic folding container body 12 with a (2n)-cornered base area, where n is any integer greater than 1, preferably n=2, 3 or 4.

Even in the case of a cube-shaped folding container body, the container lid comes to lie congruently on the container floor, but only rotated by 90°, if the above-mentioned height condition is observed. The twisting angle of the container lid relative to the container bottom during the transition from the use condition to the stowed condition generally corresponds to the internal angle enclosed between two immediately circumferentially adjacent wall sections.

As in 1 is also shown, the carrying device 14 comprises a carrying handle 50 which is detachably coupled at its two opposite longitudinal ends to connecting straps 52 and 53, the connecting straps 52 and 53 in turn being connected to the folding container body 12 by gluing and/or welding and/or riveting and/or and screwing and the like are connected by means of material strips 48.

The support device 14 is preferably designed to be mirror-symmetrical with respect to an axis of mirror symmetry containing the prism axis P. Since the connecting lugs 52 and 53 are of identical design, only the connecting lug 52 is explained in more detail below, the description of which also applies to the connecting lug 53 under the condition of mirror symmetry mentioned. Likewise, the carrying handle 50 has a mirror-symmetrical design, so that the explanation of a longitudinal end area is sufficient for this in order to describe the carrying handle 50 completely, taking into account the mirror-symmetry condition mentioned.

In the 3 until 5 an intermediate state in the coupling of the carrying handle 50 to the connecting strap 52 is shown.

The preferably roughly triangular connecting strap 52 has an opening 54 passing through the connecting strap 52 . The opening 54 has a in the 3 until 5 lower push-through section 56 with a larger cross-sectional area and a holding section 58 connected to the push-through section 56 with a smaller cross-sectional area. A common, closed peripheral edge 60 enclosing the opening 54 or the opening 54 has a constriction 62 at the transition point between the push-through section 56 and the holding section 58 . In the exemplary embodiment shown, the push-through section 56 and the holding section 58 are to be understood as circular surfaces overlapping one another in the region of the constriction 62 .

In the example shown, the connecting strap 52 is formed from 2 similar strap components 52a and 52b, which can accommodate the material strip 48 between them, by means of which the connecting straps 52 or 54 are connected to the folding container body 12 (see FIG 1 ).

The carrying handle 50 has an insertion formation 64 at each of its two longitudinal ends, with the carrying handle 50 having a handle section 66 with a larger cross-sectional area, a carrying section 68 with a smaller cross-sectional area following the handle section 66 along a following axis F, and a head section 70 with a larger cross-sectional area. The cross-sectional areas are to be considered in section planes orthogonal to the following axis. Of the three sections mentioned: handle section 66, support section 68 and head section 70, the support section 68 therefore has the smallest cross-sectional area.

The entire carrying handle 50 is preferably rotationally symmetrical with respect to the following axis F as the axis of rotational symmetry.

The carrying handle 50 can be inserted into the opening 54 along an insertion path E, which is a rectilinear insertion axis E in the illustrated embodiment. The insertion axis E is the opening surface of the essentially circular Push-through section 56 thought to be centrally enforced.

When the carrying handle 50 is arranged with its following axis coaxially to the insertion axis E, the insertion formation 64 of the carrying handle 50 can be passed through the push-through section 56 . This state is in the 3 until 5 shown.

The cross-sectional shape of the head section 70 is also circular and has a smaller diameter than the push-through section 56 but a larger diameter than the holding section 58 so that the head section 70 can only be passed through the push-through section 56 but not through the holding section 58 .

The support section 68 has a slightly smaller or the same diameter as the holding section 58. The edge 60 enclosing the opening 54 is elastic in the area of the constriction 62, so that the support section 68 is orthogonal to the following axis F past the constriction 62 from the push-through section 56 in the holding section 58 can be transferred. The constriction 62 has a dimension that is smaller than the diameter of the support section 68, so that the support section 68, once arranged in the support section 58, remains in the support section 58 without the application of external force.

With a corresponding deformation of the edge 60 of the opening 64 in the region of the constriction 62, for which a force that is at least double the weight of the carrying handle 50 is necessary, the carrying handle 50 can be removed from the connecting strap again in the opposite sequence of movements as when it was coupled to the connecting strap 52 52 to be solved. Consequently, the constriction 62 forms with the support section 68 a catch that can be overcome.

The diameters of the handle section 66 and the head section 70 are each larger than the diameter of the holding section 58, so that once the carrying section 68 has been arranged in the holding section 58, the carrying handle 50 can be carried not only in the radial direction on the connecting strap 52, but also in the axial direction along the following axis F is positively defined.

To ease the exertion of force when establishing and releasing the coupling between the carrying handle 50 and the connecting strap 52, a base section 72 of the connecting strap 52, which is preferably located between the opening 54 and the strip of material 48 connecting the connecting strap 52 to the folding container body 12, can be gripped by hand be trained.

In the 6 ; 7 and 8th the carrying handle 50 is shown coupled to the connecting strap 52 . The shifted with the carrying handle 50 following axis F is now offset radially to the engagement axis E and runs parallel to it.

As in 8th As can be seen, which shows the carrying section 68 arranged in the holding section 58 in cross section, the carrying handle 50 can be hollow at least in sections, preferably completely, in order to save weight.
