Description

Technical area

The invention relates to a stackable container system.

State of the art

Stackable containers are well known in the art. Such containers can be stacked in the state of use to form a stack of containers and preferably in the non-use state to save space.

For example, this describes DE 20 2010 000 632 U1 a transport container in which the side walls taper conically downwards and are provided in the pivotable on an upper side supports that can be pivoted in the use position in a supporting position in which they serve as a support for a similar, second to be stacked transport container.

Likewise describes the DE 81 18 115 U1 a container with a conically widening to the upper edge cross-section and with the container bottom folding feet, which allow in the unfolded state placing the container on the edge of a similar container and in the folded state insertion of the container in a similar container.

Another example of a stackable container system describes the US 2014/0305741 A1 in which both stacking and nesting of the substantially tray-like container is possible. In order to be able to move or transport a stack of the containers stacked on top of one another, the object of the US 2014/0305741 A1 a lifting unit is provided, which is mounted on a suitable vehicle, in particular on a forklift and has a plurality of support assemblies, each having a pair of prongs-like support elements which cooperate with a stack of the stackable containers such that in each case a support assembly between two containers inserted in the stack can be lifted and by pushing apart the support assemblies in the vertical direction, the resting on the support assemblies container.

A stackable container system in which the distance of the individual container levels can be adjusted by means of provided spacers, for example, describes the FR 2 967 139 A1 ,

Also usable as planters stackable containers have enjoyed increasing popularity in recent times. For example, the US 5 440 836 A stackable planters with irrigation system on. Such stackable containers for planting or for plant breeding can be used for example in cramped outdoor areas, such as on small terraces, balconies or forecourts, so that such stackable planters in particular in cities from a broad population are in demand.

The stackable planters can serve as a stackable flowerbed or as a stackable vegetable patch and can be used both for the greening of terraces, balconies or the like but also for vegetable cultivation. Such plant containers, which are also suitable for vegetable growing are increasingly desired because, for example, along with growing health awareness in a significant part of the population and the demand for naturally or organically grown, self-grown vegetables increases.

For example, describes the US 2015/0128494 A1 a stackable planter with a bottom and a rising from the ground wall, wherein the wall is provided with alternating bulges and depressions and the plant container therefore has a substantially lobed or flower-shaped cross-section. The plant container is approximately conically shaped, so that in the non-use state, several containers can be stacked or inserted into each other. To form a stack or tower in use, the vertically adjoining each container are rotated relative to each other and that radially about a vertical axis of the stack, so that in the vertical direction in each case a bulge and a recess of the stacked containers alternate. In this way, the containers in the stacked state in the region of the bulges are open at the top. This upper opening serves as a plant opening through which the plant can grow and out, thus also to the light out. To support the growing out of the upper openings of the bulges plants simple wire hanger are provided, wherein the wire hanger are respectively attached to the edge of two adjacent lobes of a container.

Further, the WO 2017/035601 A1 a stackable container system for planting, in which the containers are also designed for nesting and stacking. For stacking on top of each other arranged containers support or connecting elements provided. The containers also have a substantially lobed or flower-shaped cross section and the support or connecting elements are provided with openings which are arranged in the region of the bulges of the container and through which the plants are led to the outside. To stabilize a container stack rod elements can be provided in the container system, which are attached to two superimposed support or connecting elements.

Disadvantageously, the stackable container systems, as described above, do not allow secure stabilization of the container stacks. This proves to be particularly disadvantageous in container systems, which are also suitable for planting, and therefore are usually placed outdoors, not least for safety reasons.

Presentation of the invention

It is therefore an object of the present invention to provide a stackable container system which overcomes the disadvantages of the prior art and in which the containers stacked on top of one another in a container stack are secured and stabilized against one another, in particular. This object is achieved by a stackable container system according to the independent claim 1. Further advantageous aspects, details and embodiments of the invention will become apparent from the dependent claims, the description and the drawings.

The present invention provides a stackable container system comprising at least two stackable containers with a receiving body. The receiving body comprises at least one bottom and a rising from the bottom side wall, wherein the bottom and the side wall define a receiving space. The receiving body is set up in such a way that it is possible to stack the stackable containers in one another as well as at the other, wherein the containers are designed and set up as plant containers for the planting of plants. In the case of the container system according to the invention, at least one stabilizer device equipped with a plurality of connector sections is provided for stabilizing connection of all the containers stacked in a container stack. Each container has corresponding recesses in a container rim section for a positive engagement of the connector sections of the stabilizer device, the stabilizer device in the connected state by means of a plurality of connector sections is engaged with each container stacked in the container stack, and wherein the stabilizer device simultaneously provides a climbing aid for the plants growing in the plant containers.

In a stacked state, which can also be understood as a non-use state or non-use position, a container is received in each case by a further, similar container. In contrast, when stacked, one container is supported on another similar container, thereby forming a container stack. This is understood in the present case as a state of use. Preferably, all stackable containers have the same shape.

For stacking on the receiving body, for example, movably arranged stacking elements, which are movable at least from a first position to a second position. The movable, in particular rotatable and / or pivotable or displaceable arranged on the receiving body of the present stackable container stacking elements can be quickly and easily adjusted or moved so that they occupy at least two positions. If the stacking elements are oriented in a first position, each container can receive or be received by another such container. In their first position, the stacking elements thus allow the nesting of several similar containers. In contrast, in their second position, the stacking elements allow the placement of a container on a similar container, i. They thus block the nesting of at least two similar containers.

The corresponding recesses for a positive engagement of the connecting piece sections of the stabilizing device are arranged in a container edge portion, wherein according to the present understanding container edge portion is to be understood as an edge region or edge portion in the region of an upper side of the container. The corresponding recesses are arranged so that they are freely accessible even in the stacked state of the container, namely in a container stack, and are available for easy engagement of the connector sections of the stabilization device. For example, the recesses may be formed in a wall edge section or in a wall edge of the receiving body or, in the case of stack elements provided on the top side of the container, also in the stack elements.

The stacked containers of a container stack are arranged in a plurality of stacked stack levels, with a first, on a substrate, for example on the Floor parked container in a first stack level, a stacked on the first container second container in a second stack level and further in turn stacked thereon containers are arranged in further stack levels. The stabilizing device is preferably elongate and has a major axis along its length which, in use, intersects all of the stacking planes in a substantially perpendicular orientation. The connecting piece sections are spaced apart from one another and distributed over the stabilizing device such that at least one connecting piece section is available at the level of each stacking plane. Particularly preferably, the stabilization device is formed like a grid or a frame.

Advantageously, the container system according to the invention allows a particularly secure stabilization of a container stack by all stacked in such a container stack containers are connected by the at least one stabilizing device. Each stabilization device has a plurality of connector portions and is connected to each container of a container stack, in such a way that in each case at least one connector portion of the stabilizing device cooperates with a respective corresponding recess in a respective container. In this way, the container of a container stack are continuously, over a continuous, over the entire stack of containers extending stabilizing device secured against each other, whereby slipping and tilting of the stacked containers is effectively prevented. As understood, this also means that the containers of a container stack are mutually braced or braced to ensure a stable container stack. In particular, the containers of a container stack are thereby supported against each other.

The stabilization device can also be designed in several parts and comprise a plurality of stabilizing elements which can be connected to one another. The individual stabilizing elements are preferably fixedly and rigidly connectable to each other, such that the interconnected stabilizing elements form a sufficiently rigid and stable stabilizing device for secure stabilization of the container stack. Preferably, the individual stabilizing elements adjoin one another in the direction of the main axis of the stabilizing device. This results in advantages for the storage and transport of the stabilizing device, since the individual stabilizing elements of the multi-part stabilizing device have a small length and can be stored to save space.

Preferably, the connector portions of the example grid-like stabilizing device are in the form of pins and the corresponding recesses formed in the container edge portion of the container as blind holes. The connection of the stabilizing device with the containers of the container stack can be understood in this case as hooking or hooking. Particularly preferably, the pins, which are assigned to different stacking levels, have different spigot lengths, whereby the hooking is facilitated.

Preferably, the stabilization device is designed to connect at least three or four or five containers stacked on top of one another and arranged one above the other. In this embodiment, the stacked containers form three or four or five stack levels, with the stabilizer extending lengthwise over the entire stack height, passing through all three or four or five stack levels.

Particular advantages arise from the fact that two or three or four stabilizing devices are provided per container stack, each stabilizing device is engaged via their connecting piece sections with each stacked containers of a container stack. A particularly stable mutual strut of the container of a container stack can be achieved about it.

According to a preferred embodiment of the present invention, at least one opening is formed in the wall of the receiving body of the container. In a particularly preferred embodiment, the receiving body of the container is formed substantially in the form of a truncated pyramid with a polygonal, in particular rectangular base and comprises adjoining lateral wall sections, wherein very particularly preferably in each wall section, an opening is provided. In this way, the container is particularly well suited for use as a planter or planter. The present container system with such containers can thus be understood as a stackable plant bed.

Likewise, further openings may be provided in the wall sections or a plurality of openings within a wall section. The shape of the openings can be arbitrary, for example, round, oval, polygonal, arbitrarily symmetrical or irregularly shaped openings are possible. Embodiments are also conceivable in which the wall sections are formed preperforated, such that by breaking out surface sections along the intended perforation, a desired number and / or a desired pattern of apertures can be generated as needed. It goes without saying that even with a continuous wall, one or more openings in the wall can be provided.

Particularly preferably, the openings in an upper, remote from the bottom region of the wall, which connects from above to the container edge portion arranged. Preferably, the openings are arranged in an upper half of the container edge section or in upper two-thirds of the wall surface. This has the effect that the area of the wall adjoining the floor is designed to be closed. The inclusion of potting soil or plant granules in the lower area of the receiving space is thereby made possible without running the risk that the potting soil or plant granules is forced out. The apertures preferably occupy an area ratio in a range of 30% to 70%, more preferably 40% to 60%, and most preferably about 50% with respect to the surface of the wall or to the surface of the wall portions, i. About half of the wall surface is formed by one or more openings and is thus open to the outside. This ensures that sufficient light can penetrate to the plants in the receiving space.

Alternatively, in particularly preferred embodiments, the aperture can be made almost over the entire surface of the wall sections, as long as it is ensured that the reception of a sufficient amount of plant soil or plant granules can be achieved, especially when used as a planter.

Leaf and flower parts of creeping or hanging plants that are planted in a container partially filled with potting soil, can be passed through the opening to the outside. Very particular advantages result from the stabilization device which connects the stacked containers of the container stack. Since the stabilizing device extends over the height of the container stack and is preferably guided past the opening in the wall, in particular a grid-like or frame-like stabilization device serves in this case as a climbing aid, preferably as a trellis or as a trellis for through the opening through to the outside guided plant parts. Because the stabilization device is guided past the opening in the wall, the climbing or climbing plant parts can be brought to the trellis in a particularly advantageous manner in a simple manner.

The stabilization device may be embodied, for example, ladder-like in embodiments in which the container system for plant cultivation is used and have two longitudinal bars that are substantially vertically oriented in the position of use and a plurality of horizontal transverse bars attached thereto. The connector sections are preferably formed on the longitudinal bars, for example, formed on these or firmly connected to these. By substantially longitudinally extending longitudinal bars is meant herein that the longitudinal bars extend in a direction from top to bottom with respect to a stack of containers, wherein the longitudinal bars may be oriented to an angle in the range of 0 ° to 30 ° to the vertical preferably from 10 ° to 20 °. Likewise, the horizontal cross bars may be oriented so as to enclose with the horizontal an angle in a range of 0 ° to 30 ° or of 10 ° to 20 °. The longitudinal and transverse rods to each other may include substantially any acute angle. For example, include transverse and longitudinal bars at an angle of 30 ° or 60 °. Alternatively, the stabilization device can also be designed as a trellis grid with a plurality of parallel longitudinal bars and a plurality of transverse bars running perpendicular thereto. Likewise, embodiments are possible in which the longitudinal bars run obliquely to each other, wherein the stabilizing device essentially forms a V-shaped trellis. Also, the stabilization device may be designed as a scissors clasp.

According to an alternative preferred embodiment, the stabilizing device may be in the form of a frame-like structure, wherein the frame-like structure comprises, for example, a frame and freely and irregularly shaped supporting and / or design elements arranged inside or on the frame. In principle, the stabilizing devices, irrespective of their embodiment, are preferably designed in such a way that they allow a passage from outside into the receiving space of the receiving body.

In particular, in embodiments in which the receiving body is in the form of a truncated pyramid with a rectangular base and an opening is provided in each wall section, five containers stacked in a container stack can be combined with four stabilizing devices, such that on each of the four sides of the Container stack is provided a stabilizing device. Containers considered from below four lower stack levels may contain climbing plants, the green portion of which is led out through a respective aperture in one wall portion, in each stack level on another side of the container stack. Each plant of the first four stack levels can thus climb on a stabilization device or tendrils. It goes without saying that containers with higher-growing plants in the lowest, first stack level and containers with lower plants are arranged in further, upper stack levels. For example, in the fifth stack level, there may be a container of non-invasive plants, such as herbs.

In other embodiments, in which the receiving body has an opening in only one or two wall sections, ventilation openings can be formed in the wall, in particular in the further wall sections. A good ventilation of the receiving space is ensured in particular in the interaction of ventilation openings together with the openings in the wall.

The containers may be made of plastic, of wood, of a wood material, of composite material, of cardboard or of any combination of said materials. Especially when using cardboard or wood or wood-based material, the material may be particularly preferably coated and preferably provided with a water-impermeable coating. When using the container as a planting or cultivation container, there are further advantages that the containers are made for example of a transparent material. Made of plastic containers can be produced for example by an injection molding process. Both in the region of the bottom but also in the region of the wall stiffeners in the form of ribs or the like may be formed.

On the outside of the wall of the receiving body also web elements may be provided which serve as a stop when stacking the containers in the non-use state and thereby prevent setting of the nested containers by too deep slippage. At the bottom of the container may additionally be provided a setting edge, with particular advantages result if at the same time in the region of the container edge portion or in the stack elements, provided that they are arranged on the receiving body, a groove for receiving the setting edge. Especially with truncated pyramidal receiving bodies edges and corners can be chamfered and / or rounded. Particular advantages result from the fact that the edges are chamfered in the connection areas of the wall sections and are provided with a concave curvature, as can be directed over it, for example, water or run outside.

In order to effectively prevent the accumulation of waterlogging, in particular when using the containers as planting containers, at least one drainage opening is provided in the region of the bottom of each container of the container system. In the present case, a drainage opening arranged in the region of the floor is understood to mean that the drainage opening is arranged in the floor or at a transition from the floor to the wall or in a section of the wall adjoining the floor, which immediately follows the transition between the floor and the wall. A drainage opening arranged at the transition from the floor to the wall can thus also have two opening sections, a first opening section being formed in the floor and a second opening section being formed in the wall. Advantageously, the bottom of the receiving body for receiving the liquid present in the receiving space and for guiding the liquid received in the direction of the at least one drainage opening is formed. Thereby, a discharge or discharge of the liquid from the receiving space is particularly advantageously possible. For example, the drainage opening may be designed and arranged such that the exiting liquid is discharged from the receiving space such that it either flows outside, preferably guided, at the container stack or that it is introduced into containers which are arranged below in the container stack and along an inner Side of the wall in the receiving space of the container is guided down.

Particularly preferably, at least one of the stacking elements has a drainage channel which is designed to receive and discharge liquid. Due to the drainage opening formed in the region of the bottom of the receiving body in conjunction with the special design of the floor and preferably in cooperation with the drainage channels of the stacking elements, a discharge of liquid or a drainage can be carried out very advantageously in the use state of the container system. The liquid collecting in the receiving space, for example excess irrigation water, is directed to the at least one drainage opening and can escape there accordingly, wherein the at least one drainage channel of at least one stacking element, at least in the use position of the container system, is arranged such that it emerges from a drainage opening Liquid enters directly into the drainage channel and can be derived via this. Preferably, the at least one drainage opening and the at least one act Drainage channel of one or more container (s) for discharging the liquid present in the receiving space together.

Preferably, the receiving body has a plurality of drainage openings, wherein the drainage openings provided are arranged adjacent to the wall in the ground or formed in a connection region of the wall to the floor. In the arrangement and distribution of the drainage openings is only to ensure that each drainage opening in the position of use of the container cooperates with a drainage channel of a stacking element and therefore leaking liquid is collected accordingly in a drainage channel. The drainage openings are formed for example in the form of simple holes and can have a wide variety of cross-sectional shapes, such as round, oval or polygonal cross-sectional shapes or slit-shaped. The size or cross-sectional area of the drainage openings is preferably many times smaller than the area of the floor, so that the total area of all the drainage openings occupies, for example, only a fraction of the floor area.

Particular advantages arise when the floor is arched. Additively or alternatively, the bottom may preferably also be inclined. By means of an inclined or curved design of the floor, it can be ensured, for example, that the liquid or moisture present in the receiving space, which precipitates or collects on the floor, flows in the direction of the wall and is received at least in sections along the wall. Particularly preferably, the floor has a protruding in the direction of the receiving space convex curvature. For example, a concavo-vaulted floor is possible. Depending on the arrangement and position of the drainage openings and a concave curved bottom may be conceivable. In particular, by adjusting the curvature or the inclination with the position of the drainage openings, a particularly effective liquid discharge from the receiving space can be effected.

Particularly preferably, the floor comprises at least two adjoining inclined floor sections, the floor sections adjoining one another at a higher leveling point and each dropping at a predetermined angle of inclination in the direction of the wall to a lower leveling point. In this preferred embodiment of the floor, the number of drainage openings and the number and inclination of the floor sections can be coordinated with one another in such a way that an effective discharge of water takes place.

In alternative embodiments, it is also conceivable to make the at least one or more drainage openings of a specific container closable within a container stack. For this purpose, for example, simple plugs or closure caps can be provided or regulable closures with an adjustable valve, via which, for example, additionally a drain hose and / or a tap can be connected. In particular, when using the container as a nursery or cultivation container, this proves to be advantageous because, for example, an excess of irrigation water from the containers of a container stack derived and collected in a non-planted container, for example, and can be recycled from there. The collected water may e.g. also be used for irrigation of other, adjacent or in the vicinity of set up container stacks, for example by using a suitable conduit or transport system for the distribution of the collected water. For example, a suitably designed hose and / or pumping system can be used for this purpose. It goes without saying that the collected water can be used for irrigation of containers arranged on different levels of the same or other container stacks.

In the same way, it is possible that a container with such closed drainage holes forms a reservoir or water supply and thus serves as a basis for an irrigation system or for an automatic drip irrigation to the other planted container in the container stack or other planted container in adjacent or in accessible stacks prepared to be irrigated as needed.

In order to achieve a continuous liquid line or water supply in the stackable container system, the stacking elements preferably further comprise a communicating with the drainage channel communicating passage for selectively guiding the liquid collected in the drainage channel from a first side of the stacking elements to an opposite second side of the stacking elements on. The passage is preferably in the form of a funnel-like bore, but may alternatively also be a passage with a substantially polygonal cross-section. For example, the passage in the stacking elements selectively guides and directs the liquid from the drainage channels from an upper side or top surface of the stacking elements, namely, the first side of the stacking elements to a lower side, namely, the second side. Since in a container stack, the drainage channels of the stacking elements with the drainage openings of the same or a co-operate further container is a conduit of liquid from top to bottom essentially mediated via the stack elements.

Depending on the arrangement of the passage, preferably the funnel-like bore, in the stacking element is therefore a forwarding or guiding the liquid from one container to the next below arranged container possible, either in the form that the liquid is introduced into the receiving space of the lower container or is discharged or derived on the outside of the wall of the receiving body of the lower container. In particular, when using the container as planter resulting in particular advantages.

For example, it is possible to introduce into the funnel-like bore a hose or a pipe or a drain pipe, wherein the hose or the tube preferably has a flared end over which the hose or tube is sunk in the funnel-like bore sunk. By means of such a hose or tube or such a drainpipe, a drainage system can be formed in order, for example, to redirect the liquid specifically into further containers of a container stack or to collect it in other collecting containers.

Particularly preferably, a targeted, guided, inside liquid flow can be accomplished that at least one fluid channel is provided for guiding liquid, which is arranged on an inner side of the wall facing the receiving space and communicates with the at least one drainage opening, wherein a first End of the fluid channel is in communication with the drain hole and a second end of the fluid channel having an inlet opening for the entry of the liquid.

Very particular advantages arise from the fact that the passage with the inlet opening of the fluid channel of one or more container (s) for inside guiding and discharging the liquid acts together. A controlled and guided, substantially continuous line of the liquid can be ensured, which in particular when used as a planter the possibility is opened, targeted catch and reuse excess irrigation water or rainwater. Also, a substantially automatic drip irrigation of all containers of a container stack or even adjacent container stack can thus be realized, and preferably regardless of which stack level in which the containers are arranged.

Alternatively, it is also possible to derive the water outside the receiving body outside, for example along designated drainage grooves or drainage grooves on an outer surface or outside of the wall. Depending on the use and configuration, this can be advantageous for the overall concept of the container system. Such drainage grooves or drainage grooves can be formed, for example, on the outside in the corner regions, namely in the region of the adjoining wall sections of truncated pyramid-shaped receiving bodies. For example, this can be effected by chamfered or rounded or concave corner areas.

Very particularly preferably at least one shelf is provided in the receiving space further, wherein the shelf is supported by means designed for this, provided on the wall of the receiving body holding webs at a predetermined position in the receiving space. For example, when using the containers as planters, it is also possible to provide a water-permeable shelf in the receiving space on which the plant soil or the plant granules are stored. Below the shelf can thereby be created a space in which, for example, by closing the drainage irrigation water can be collected.

The guide groove is, for example, set up so that interaction with the drainage channels of the stacking elements is possible so that effective drainage can take place over it. It is also possible to additionally provide a sump in which a container or the lowest container of a container stack is turned off. Such a collecting tray is particularly suitable for collecting excess irrigation water and serves as a reservoir for water that can be removed or conveyed in various ways. For example, this can be done manually or by using appropriate means and a mechanical or electrical removal. To empty the sump, a valve or tap can be installed at a suitable place or at several points.

Furthermore, in preferred embodiments, grooves or grooves or grooves are provided on the lateral wall, particularly preferably on the outside of the lateral wall, which are designed to collect precipitation water impacting the wall, to collect it and to introduce it into the drainage channels of the stack elements. The grooves or joints or grooves can be designed as an integral part of the receiving body and already made as a unit with the receiving body, for example, be formed on the wall. Alternatively, gutters can or joints or grooves but also be prepared separately and be arranged on suitable connection means or coupling means on the wall of the receiving body or connected thereto.

The stack elements can be pivoted, for example, about a pivot axis or can be displaced in the direction of a displacement axis. Furthermore, the stacking elements can be arranged on an upper side and / or on an underside of the receiving body. For example, the stacking elements can also be attached to the receiving body via a combined pull-out and folding mechanism. In such embodiments, each stacking element may preferably be attached to the receiving body by means of suitable guide means, for example via telescopic rails or rods or slide rails, such that it is arranged in the non-use state along the wall of the receiving body, preferably on the inside of the wall, and is tensioned. Folding movement can be unfolded. For example, a kind of pocket or an insertion or insertion section can additionally be provided on the receiving body for each stacking element, into or into which the stacking element can slip in the non-use state. In the present case, movably arranged stacking elements also mean that the stacking elements are detachably fastened to the receiving body. The stack elements can be inserted in particular in designated pockets or insertion or insertion sections of the receiving body, if the container is in the non-use state.

According to a preferred embodiment of the present invention, two strip-shaped stacking elements are provided on the upper side of the receiving body, each strip-shaped stacking element having two drainage channels arranged in the region of its end regions. The strip-shaped stack elements are particularly preferably formed pivotable. In particularly preferred embodiments, the provided on the top, pivotable stacking elements can be dimensioned so that they form a cover at the same time. For example, either two stack elements can cooperate here in order to jointly cover the upper-side opening of the receiving body or a stacking element has dimensions adapted to the geometry of the upper-side opening in order to form a cover.

According to an alternative preferred embodiment, at least two, preferably four displaceably formed stacking elements are provided on the underside of the receiving body, wherein, for example, each stacking element can each have a drainage channel.

On the receiving body provided additional grip elements or carrying handles can serve as well as the stack elements as gripping means to carry the container.

According to a preferred embodiment, in particular when using the stackable container as a plant container in the region of the receiving body at least one light source or a lighting arrangement is provided, which (s) is equipped with its own power supply or with a connection device for connection to an external power supply. The at least one luminous means or the luminous means arrangement can be arranged in the receiving space of the receiving body or on the outside of the receiving body or on an upper side of the receiving body, such that, for example, the receiving space can be illuminated.

The at least one luminous means or the luminous means arrangement is preferably designed to emit a light having a wavelength which promotes plant growth, and is preferably controllable in such a way that the light is emitted over predetermined periods of time and / or at given times of the day. For example, the luminous means or the luminous means arrangement can be regulated so that the light is emitted after sunset or, if a use of the stackable container is provided as a planter in rooms without daylight, also all day or periodically with predetermined time intervals. For example, a battery or an accumulator is provided for supplying energy to the luminous means or the luminous means arrangement. Furthermore, a solar panel in combination with a suitable storage device can be provided for the energy supply.

Several juxtaposed or successively arranged container stacks can be connected to each other by means provided for connecting and securing elements and secured against each other. Just connections in which the container stacks are aligned with each other, are just as possible as connections over corner. It is also possible via a suitable design of the connecting and securing elements to allow the connection of containers which are arranged at different height level, for example in different stack levels.
