CONTAINER, AND A KIT OF BLANKS CONFIGURED TO BE ERECTED TO

FORM A STORAGE CONTAINER AND A SUBCONTAINER

Field of invention

The present invention relates to a blank configured to be erected to form a storage container. The storage container is configured to be capable of receiving one or more subcontainers that may be recycling containers. The invention further relates to a kit of blanks configured to be erected to form a storage container and a subcontainer. Technical background

Recycling of waste is widely practiced to create new products or materials. Different types of waste generally need to be recycled by use of different procedures. For example, metal and cardboard waste products are typically treated using different recycling processes. Separating waste, dependent on the type of the waste, requires separate storage bins for different types of waste. However, it can be place-consuming, unpractical and un-aesthetic for customers to separately store their recyclable waste at home. It would be useful for the customers to have a possibility of a practical and esthetical separate storage of different types of waste at home or elsewhere.

Another problem with storage of the waste is that waste bins become dirty and un-hygienical after a time of use. Plastic and/or paper bags can be used for keeping the waste bins fresh inside and/or to facilitate emptying of the bins. However, throwing a paper and/or plastic bag every time there is a need of emptying the bin causes an undesired environmental impact. Therefore, there is a need of a solution that allows bins to be emptied without necessitating the use of a disposable plastic and/or paper bag being thrown away every time a bin is emptied.

Further, there are situations when a permanent waste storage is not required, but a possibility of easy use and discard of the waste storage is valuable. When used for a shorter time, there is no need of a permanent solution, but a semi-permanent solution is preferred. For example, if a separate waste storage is used during a holiday period while caravanning or during an exhibition, it would be convenient to have a possibility of discarding the waste storage with a minimal environmental impact when its general condition deteriorates and the bin becomes aesthetically undesirable or even turns into un-useful, and/or when there is no more need of it.

There are various kinds of recycling bins presently used. They come in various shapes, sizes and materials. Although recycling bins made of stiff material, such as boxes made of moulded plastic, typically are robust, such boxes tend to occupy a large space when not in use, as while transported or stored in order to be sold, and such boxes also often make use of large amounts of material. On the other hand, recycling bins made of comparably soft or light material, such as recycling bins formed by folding paper-based blanks, often requires specific measurements to provide sufficient stability.

Various kinds of storage containers for storage of one or more recycling bins for different types of waste are presently used. They come in various shapes, sizes and materials. The same reasoning as above regarding the material choice for the recycling bins can be applied to the material choice for storage containers.

From a user perspective, the storage containers and/or the recycling bins preferably have a lid. The lid may be useful for preventing odours coming out of the bins, for obstructing access and/or keeping the waste in the bins out of sight. An easy access to the bins is though preferable. From a manufacturing and from a user perspective, a prevention of a loss of the lid during storage or transport of the storage container is desirable.

From a manufacturing and from a user perspective, the storage containers and the recycling bins preferably address the design criteria of making efficient use of material, being possible to transport as flat-laid blanks, being easy to erect to form the storage container and the recycling bin, being capable of forming storage containers and recycling bins being stable when in use and being capable of providing a lid. Preferably, this should be accomplished with a minimal use of adhesive, and especially preferably without the need for application of an adhesive at the site of use. Preferably, this should be accomplished without the need of tools.

An example of a storage container formed by folding a blank is disclosed in GB2446682. The document discloses a recycling waste container comprising a plurality of bins. The recycling waste container is provided with a common lid and holds the bins together as a unit. In addition, each bin has an inlet in its side wall for depositing waste within the bin whilst the common lid is closed. The inlet is closable by a pivotal flap. Each bin includes a hand hold aperture and a cutaway portion for securing a waste bag within the bin. All the bins fit in a common support base which also include a sliding drawer. Each bin and the common base are formed from a respective sheet of flexible material by a folding operation. The common lid is pivotally mounted on the base. The back wall of the recycling waste container has a flap that is joined to the edge of a side by a strong adhesive.

Thus, there is still a need to provide an improved concept of providing a storage container and/or recycling bin which from a manufacturing and from a user perspective, address one or more of the design criteria of making efficient use of material, being possible to transport as flat-laid blanks, being easy to erect to form the storage container and the recycling bin, being capable of forming storage containers and recycling bins being stable when in use, and being capable of providing a lid. Preferably, this should be accomplished with a minimal use of adhesive, and especially preferably without the need for application of an adhesive at the site of use. Preferably, this should be accomplished without the need of tools.

Summary of invention

The object of the invention is to provide an improved concept of providing a storage container and/or recycling bin for the convenient storage of different types of goods, such as recyclable waste, the concept of providing a storage container and/or recycling bin adequately addressing one or more of the design criteria concerning making efficient use of material, being possible to transport as a flat-laid blank, being easy to erect to form a storage container and/or recycling bin, and being capable of forming a stable storage container capable of receiving one or more subcontainers, such as one or more recycling bins. Preferably, this should be accomplished with a minimal use of adhesive, and especially preferably without the need for application of an adhesive at the site of use. Preferably, this should be accomplished without the need of tools.

This object has in accordance with a first aspect been achieved by a blank configured to be erected into a storage container. The storage container is configured to be capable of receiving one or more subcontainers, such as one or more recycling bins.

The blank comprises: a bottom panel, a rear wall panel and a lid panel arranged one after the other along a longitudinal direction as seen in flat-laid state of the blank, a first side panel foldably connected to a first transversal side of the bottom panel and a second side panel foldably connected to a second transversal side, opposite the first transversal side, of the bottom panel, one or more bottom front rim panels being configured to form a bottom front rim and being foldably connected to a longitudinal side of the bottom panel being opposite to a longitudinal side of the bottom panel being connected to the rear wall panel, one or more lid front rim panels being configured to form a lid front rim and being foldably connected to a longitudinal side of the lid panel being opposite to a longitudinal side of the lid panel being connected to the rear wall panel, wherein the bottom front rim and the lid front rim together have a total extension along the longitudinal direction being less than a longitudinal extension of the rear wall panel such that an open front is formed when the blank is erected into said storage container.

By designing the blank as stated above, there is provided a storage container which is capable of receiving one or more subcontainers, such as one or more recycling bins. The storage container has a lid, which is formed from a lid panel forming part of the blank configured to be erected into the storage container. The attachment of the lid panel prevents the loss of the panel during transport and/or storage. The storage container has an open front. The provision of an open front facilitates access to the subcontainers. Moreover, the blank is easy to erect to form a storage container. Furthermore, the design of the blank allows a minimal use of adhesive. Moreover, there is no need of special tools and/or skills to form the storage container of the blank. It is further to be noted that the blank, configured to be erected into the storage container, is easy to transport being a flat-laid blank when unfolded.

Through-out the description the phrase transversal side or transversal edge relates to a side or edge encountered when moving along the transversal direction and the phrase longitudinal side or longitudinal edge relates to a side or edge encountered when moving along the longitudinal direction. For a rectangular panel a transversal side or edge will be positioned on a side as seen along the transversal direction and will have an extension along the longitudinal direction and a longitudinal side or edge will be positioned on a side as seen along the longitudinal direction and will have an extension along the transversal direction.

The blank may further comprise a first attachment panel foldably connected to a longitudinal side of the first side panel and a second attachment panel foldably connected to a longitudinal side of the second side panel, the first and the second attachment panels being configured to abut the rear wall panel when the blank is erected into said storage container. By the provision of the attachment panels, the side panels are easily fixed relative to the bottom panel and the rear wall panel. Thereby it is easy to provide a stable and robust storage container. The provision of such designed attachment panels makes it easy to attach the attachment panels to the rear wall. They may be attached by providing a small amount of adhesive, such as a small amount of hot-melt glue. They may be attached by a simple stapling action. They may be attached by an adhesive tape. The adhesive tape may be an adhesive double-sided tape between the attachment panels and the rear wall panel. The adhesive tape may be an adhesive single-sided tape extending from an attachment panel to the rear wall panel and optionally also to the other attachment panel.

The first and the second attachment panels may be configured to be adhesively attached to the rear wall panel when the blank is erected into said storage container. The adhesive manner of attachment facilitates forming of the storage container. The additional material needed for such adhesive attachment is minimal. Moreover, the use of adhesive attachment facilitates and provides a design-freedom in the design of the blank and the storage container formed of the blank. Moreover, adhesive attachment removes the need of special tools for forming the storage container.

The first and the second attachment panels may be configured to be adhesively attached to the rear wall panel by use of one or more adhesive strips, the adhesive strips preferably being pre-attached to the rear wall panel or the attachment panels, preferably to the rear wall panel. The usage of adhesive strips facilitates forming of the storage container. The result is that the procedure of forming the storage container becomes time-efficient and straight forward. Pre-attachment of the adhesive strips makes the blank ready-to-use. There is no need of special tools for forming the storage container. As the strips are pre-attached, the customer does not need to handle chemicals or tools that can be potentially injurious to health. The adhesive strip may be formed of an adhesively double-sided tape with a first side thereof being pre-attached to the rear wall panel or the attachment panels and a second side, opposite the first side, being covered by a protective strip of material having a non-adhesive side facing away from the rear wall panel or the attachment panels to which the adhesively double-sided tape is pre-attached. Thus, the only part to be discarded after forming the storage container is then a protective strip, such as a paper or plastic strip, pre-attached to the adhesive strip, which protective strip is removed just before the attaching of the attachment panels to the rear wall panel.

The side panels each may have a portion having an extension in the transversal direction being equal to an extension of the rear wall panel in the longitudinal direction. Thereby, a transversal outer edge of said portion of the respective side wall panel will end up on the same height as the upper edge of the rear wall panel. Thereby, said portion of the respective side wall may form a support against which the lid panel rests when the lid is closed. Thus, said portions may be used to prevent the top lid panel from falling in direction towards the rear wall panel when no subcontainer is inserted, or when the subcontainer has a height lower than the height of the rear wall of the storage container.

Said portions may have an extension in the longitudinal direction. By designing the side walls such that said portions have an extension in the longitudinal direction, stability is improved.

The extension in the longitudinal direction also provides protection to the side panel, since the pressure from the lid panel, when shut, is distributed along an upper edge - a transversal edge as seen in the flat-laid state - of each of the side panels.

The portion may be situated in connection with a longitudinal side of the respective side panel being configured to be situated at the rear wall panel when the blank is erected into the storage container. Such configuration provides stability to the storage container and still allows the side wall panels to be designed such that the sides of the storage container are relatively open, since the portion will, when the blank is erected, be positioned basically as an extension from the rear wall panel.

An upper front comer portion of the respective side panel may be chamfered such that an upper front edge extending from the portion towards said one or more front rim panels is formed. The chamfering of said corner portions extends the lifetime of the storage container. The reason is that said corner portions, if not chamfered, would be worn out faster. The comer portions would be exposed to damages caused by insertion of the subcontainer. The corner portions would, moreover, be exposed to damages caused by shutting the lid panel. That would cause the corner portions being slack and un-aesthetical. The comer portions may even cause inconvenience putting the subcontainer down as the comer portion may block the insertion of the subcontainer. Thus, the chamfering of the comer portions easies insertion of the subcontainers.

The lid front rim may comprise: a first and a second lid front rim panel arranged one after the other along a longitudinal direction as seen in flat-laid state of the blank, the first lid front rim panel being foldably connected to the lid panel and the second lid front rim panel being foldably connected to the first lid front rim panel such that a double-walled lid front rim is formed. By designing the blank as stated above, there is provided a storage container which has a stable lid. The rear wall panel, the lid side panels, and the lid front rim panels around the four sides of the lid panel may be said to form a rim around the lid panel when the storage container is erected. Such a double-walled lid front rim may be designed as self-locking by providing locking protrusions or tabs on the second lid front rim panel, the locking protrusions or tabs being insertable into apertures in the fold line between the first lid front rim panel and the lid panel. A double-walled lid front rim may also be used to lock neighbouring portions of the lid rim in the desired position.

The blank may comprise: a lid side panel foldably connected to each transversal side of the lid panel, and a lid locking tab extending from a longitudinal side of each lid side panel and being configured to be positioned between the first and second lid front rim panels. The lid locking tabs may be configured to be folded towards a central portion of the respective lid front rim panel to allow the lid locking tabs to be inserted between the transversely opposing lid front rim panels when the first lid front rim panel is folded over the second lid front rim panel and said lid front rim panels forming a double- walled lid rim panel. By the provision of the lid locking tabs, the lid front rim panels and the lid side panels are easily fixed in the intended position. The lid locking tabs may be said to form a part of the lid front rim and thereby also become a part of the double-walled lid front rim. The provision of the lid locking tabs makes it possible to keep the lid front rim and the lid side panels in the intended position without the use of any adhesive.

The bottom front rim may comprise: a first and a second bottom front rim panel arranged one after the other along a longitudinal direction as seen in flat-laid state of the blank, the first bottom front rim panel being foldably connected to the bottom panel and the second bottom front rim panel being foldably connected to the first bottom front rim panel such that a double- walled bottom front rim is formed. By designing the blank as stated above, there is provided a stable storage container. The rear wall panel, the side wall panels, and the bottom front rim around the four sides of the bottom panel may be said to form a rim around the bottom panel when the storage container is erected. By designing the blank as stated above, there is provided a storage container having the bottom front rim that is stable and robust. Moreover, by providing such a rim, the subcontainer/-s stored in the storage container is prevented from falling out.

In a preferred embodiment, the blank may comprise a bottom locking tab extending from a longitudinal side of each side panel and being configured to be positioned between the first and second bottom front rim panels. The bottom locking tabs may be configured to be folded towards a central portion of the respective bottom front rim panel to allow the bottom locking tabs to be inserted between the transversely opposing bottom front rim panels when the first bottom front rim panel is folded over the second bottom front rim panel and said bottom front rim panels forming a double- walled bottom front rim panel. By the provision of the bottom locking tabs, the bottom front rim is easily fixed in the intended position. The bottom locking tabs may be said to form part of the bottom front rim and thereby also become a part of the double-walled bottom front rim. The provision of the bottom locking tabs makes it possible to keep the bottom front rim panel in the intended position without the use of any adhesive. By designing the blank as stated above, there is provided a storage container having the bottom front rim that is stable and robust.

According to a second aspect, the above object has also been achieved by a kit of blanks comprising: the blank of the kind disclosed above and as disclosed in more detail below, the blank being configured to be erected into a storage container, and at least one subcontainer blank configured to be erected into a subcontainer. The subcontainer blank comprises a plurality of side walls foldably connected to each other one after the other along a transversal direction as seen in flat-laid state of the subcontainer blank, and a plurality of bottom flaps being foldably connected to the side walls and being configured to form a bottom wall of the subcontainer by being inwardly folded and interlocked.

By designing the blanks as stated above, there are provided a stable storage container and a subcontainer. Such kit is ready to be formed and used by a customer. There is no need of searching for / buying a subcontainer to be suitable for fitting into the storage container.

The subcontainer blank may comprise a first side wall, a second side wall, a third side wall, a fourth side wall, and a tab foldably connected and arranged one after the other along a transversal direction as seen in flat-laid state of the subcontainer blank. The tab may be configured to attach the first side wall and the fourth side wall together. The subcontainer blank may further comprise a first bottom flap foldably connected to a longitudinal side of the first side wall, a second bottom flap foldably connected to a longitudinal side of the second side wall, a third bottom flap foldably connected to a longitudinal side of the third side wall, and a fourth bottom flap foldably connected to a longitudinal side of the fourth side wall, wherein said bottom flaps are configured to form a bottom wall of the subcontainer by being inwardly folded and interlocked.

In the kit of blanks, the blanks may be formed of a paper-based foldable material. By providing such paper-based foldable material the blanks become easy to erect to form a storage container and a subcontainer and since the weight of the material is typically comparably small the blank becomes easy to transport from a weight perspective. A paper-based material is often possible to recycle which addresses the criteria of providing an environmentally friendly storage container and subcontainer. Moreover, paper-based material belongs to an inexpensive group of materials. It may be noted that it is conceivable to use a paper-based foldable material as a blank for the storage container and another material for the subcontainers. The subcontainers may e.g. be formed of a foldable polymer-based material. Alternatively, the subcontainers may be formed from a stiff material and may as such be shaped in the final form or may as such be designed as stiff panels being foldable about fold lines or hinges interconnecting the panels. In the kit of blanks, the blanks may be formed of a water-resistant material, preferably by providing a polymer-based coating on a paper-based foldable material. By providing the kit of blanks of such a water-resistant material, it reduces the risk that water content in the waste damages the material and it makes it easier for the customer to clean surfaces of the storage container and the subcontainer. That extends the lifetime of the storage container and the subcontainer as they stay fresh for a longer time. Furthermore, usage of the water-resistant material makes the storage container and the subcontainer more hygienical. As the storage container and the subcontainer can be cleaned/ washed, there is no need of a plastic/paper bag inside the storage container and the subcontainer in order to keep them clean. Therefore, the environmental impact of throwing waste can be further decreased. It may be noted that it is conceivable to use different materials, when it comes to water-resistance, in the storage container and in the subcontainers. It is e.g. conceivable to have the inside of the subcontainers being provided with a water-resistant coating. It is conceivable to provide a water-resistant coating on the inside of the storage container to improve its resistance to water originating from the waste thrown in the subcontainers. Alternatively, or as a complement, it is conceivable to provide a water- resistant coating on the outside of the storage container to improve its resistance to water originating from the outside environment. It is also conceivable that only one of the blanks is made water-resistant and that the other e.g. is made of a paper-based material not being made water-resistant.

In short the invention may be said to relate to a blank configured to be erected into a storage container configured to receive one or more subcontainers, the blank comprising: a bottom panel, a rear wall panel and a lid panel, a first and a second side panel foldably connected to a respective transversal side of the bottom panel, one or more bottom front rim panels being configured to form a bottom front rim, one or more lid front rim panels being configured to form a lid front rim, wherein the bottom front rim and the lid front rim together have a total extension along the longitudinal direction being less than a longitudinal extension of the rear wall panel such that an open front is formed when the blank is erected into said storage container.

With reference to figure 1 , there is disclosed a blank 1 configured to be erected into a storage container 100 (figure 2). The blank has an extension in a longitudinal direction L, and an extension in a transversal direction T, as seen in a flat-laid state of the blank 1. As evident from figure 1 , the blank 1 is provided with fold lines and cuts which define different parts and panels being configured to form the storage container. Generally, solid lines represent cut lines and dotted lines represent fold lines. The storage container 100 is configured to be capable of receiving one or more subcontainers that may be recycling containers/bins.

The blank 1 comprises: a bottom panel 10, a rear wall panel 20 and a lid panel 30, arranged one after the other along a longitudinal direction L as seen in flat-laid state of the blank. The blank 1 further comprises a first side panel 11 foldably connected to a first transversal side of the bottom panel 10 and a second side panel 13 foldably connected to a second transversal side, opposite the first transversal side, of the bottom panel 10. The blank 1 further comprises one or more bottom front rim panels 12a, 12b, being configured to form a bottom front rim 12 and being foldably connected to a longitudinal side of the bottom panel 10 being opposite to a longitudinal side of the bottom panel 10 being connected to the rear wall panel 20. The blank 1 further comprises one or more lid front rim panels 32a, 32b, being configured to form a lid front rim 32 and being foldably connected to a longitudinal side of the lid panel 30 being opposite to a longitudinal side of the lid panel 30 being connected to the rear wall panel 20, wherein the bottom front rim 12 and the lid front rim 32 together have a total extension d ₁₂ , d ₃₂ along the longitudinal direction L being less than a longitudinal extension of the rear wall panel 20 such that an open front is formed when the blank 1 is erected into the storage container 100. The bottom panel 10 constitutes the bottom of the storage container 100. The bottom of the storage container 100 is the part being typically horizontal to the ground.

The bottom panel 10 is defined by four fold lines: a fold line FL11 between the bottom panel 10 and the first bottom front rim panel 12a, a fold line FL12 between the bottom panel 10 and the first side panel 11 , a fold line FL13 between the bottom panel 10 and the second side panel 13, and a fold line FL14 between the bottom panel 10 and the rear wall panel 20. The rear wall panel 20 is defined by two fold lines: the fold line FL14 between the bottom panel 10 and the rear wall panel 20, and a fold line FL15 between the rear wall panel 20 and the lid panel 30. The lid panel 30 is defined by two fold lines: the fold line FL15 between the rear wall panel 20 and the lid panel 30, and a fold line FL16 between the lid panel 30 and the first lid front rim panel 32a.

The bottom panel 10 may be configured to be perpendicular to the rear wall panel 20, to the first and the second side panels 11 , 13, and preferably also to the bottom front rim 12, when the blank 1 is erected into the storage container 100. The bottom panel 10 may also be parallel to a top surface 30 when the blank 1 is erected into the storage container 100.

Fig. 1 further discloses the first side panel 11 that may be foldably connected to a first transversal side of the bottom panel 10, and the second side panel 13 foldably connected to a second transversal side, opposite the first transversal side, of the bottom panel 10. The first side panel 11 is an extension of the bottom panel 10 in a direction opposite the transversal direction T and is defined by the fold line FL12 between the bottom panel 10 and the first side panel 11. The second side panel 13 is an extension of the bottom panel 10 in the transversal direction T and is defined by the fold line FL13 between the bottom panel 10 and the second side panel 13.

The blank 1 may also comprise a first attachment panel 22 foldably connected to a longitudinal side of the first side panel 11 , and a second attachment panel 24 foldably connected to a longitudinal side of the second side panel 13. The first and the second attachment panels 22, 24 are configured to abut the rear wall panel 20, when the blank 1 is erected into said storage container 100. The first attachment panel 22 is an extension of the first side panel 11 in the longitudinal direction L and is defined by a fold line FL22 between the first side panel 11 and the first attachment panel 22. The second attachment panel 24 is an extension of the second side panel 13 in the longitudinal direction L and is defined by a fold line FL24 between the second side panel 13 and the second attachment panel 24. Each attachment panel 22 and 24 may have another shape than disclosed in Figure 1. The attachment panels 22 and 24 may differ in length and/or height, which is not disclosed in Figure 1. The first and the second attachment panels 22, 24 may be configured to be attached to a major surface of the rear wall panel 20. The major surface may be a major surface configured to form an inside surface of the storage container 100. According to another embodiment, the first and the second attachment panels 22, 24 may be configured to be attached to a major surface of the rear wall panel 20 being configured to form an outside surface of the storage container 100. The attaching position of the first and the second attachment panels 22, 24, in relation to the rear wall panel 20, may depend on the intention of use of the storage container 100. Attachment of the first and the second attachment panels 22, 24 to the outside surface of the rear wall panel 20 may benefit lifetime of the storage container 100 due to the upper corners of the attachment panels not being exposed to the friction occurring when a subcontainer is inserted into the storage container 100. On the other hand, attachment of the first and the second attachment panels 22, 24 to the inside surface of the rear wall panel 20 may benefit aesthetical appearance of the storage container, which may be preferred during use of the storage container 100 during, for example, an exhibition. Moreover, it reduces the risk that a person walking by the storage container 100 accidentally cuts himself on the otherwise exposed upper edges of the attachment panels 22, 24.

The first and the second attachment panels 22, 24 may be of a different shape than the shape shown in Figure 1. Other shapes can be useful for various purposes, especially when the first and the second attachment panels 22, 24 are attached to the outside surface of the rear wall panel 20. Such other shapes may also be useful to reduce the risk that a person walking by the storage container 100 accidentally cuts himself on the exposed edges of the attachment panels 22, 24.

The first and the second attachment panels 22, 24 may be configured to be adhesively attached to the rear wall panel 20 when the blank 1 is erected into said storage container 100. The adhesive attachment of the rear wall panel 20 to the first and the second attachment panels 22, 24, when the blank is erected into said storage container 100, may be achieved by use of glue and/or adhesive strips 62, 64.

The first and the second attachment panels 22, 24 may be configured to be adhesively attached to the rear wall panel 20 by use of one or more adhesive strips 62, 64, the adhesive strips 62, 64 preferably being pre- attached to the rear wall panel 20 or said attachment panels 22, 24, preferably to the rear wall panel 20. The adhesive strips 62, 64 may be pre- attached during manufacturing process. Such pre-attached adhesive strips 62, 64 is preferably adhesively double-sided strips 62, 64 with the exposed surface being covered by a non-adhesive strip, such as paper strip.

The adhesive strips 62, 64 may be unmounted strips. The unmounted strips may, for example, be sold/provided separately and/or be attached as separate units when sold/provided. The adhesive may be attached to the first and the second attachment panels 22, 24 and/or on the rear wall panel 20.

The first side panel 11 may have a portion 11a having an extension d _1a in the transversal direction T being equal to an extension d _2a in the longitudinal direction L of a first transversal side 20a of the rear wall panel 20. The second side panel 13 may have a portion 13a having an extension dib in the transversal direction T being equal to an extension d _2b in the longitudinal direction L of a second transversal side 20b of the rear wall panel 20. Said extensions d _1a , d _1b of the side panels 11 , 13 may differ from each other in length. It is preferred that at least one, more preferably both, of the side panels 11 , 13 have an upper edge on the same height as the upper edge of the rear wall 20.

The portion 11a of the first side panel 11 having an extension dia in the transversal direction T may have an extension d _3a in the longitudinal direction L. The portion 13a of the second side panel 13 having an extension dib in the transversal direction T may have an extension d _3b in the longitudinal direction L. Preferably, the extension d _3a and/or the extension dab in the longitudinal direction L is at least 10% of the longitudinal extension d ₄ of the bottom panel 10. Preferably, the extension daa and/or the extension dab in longitudinal direction L is less than 75% of the extension d* of the longitudinal extension of the bottom panel 10.

Said portions 11a, 13a may be situated such that they extend along the fold lines FL22, FL24 between the side panels 11 , 13 and the respective attachment panel 22, 24. Said portions 11a, 13a may though be configured differently than shown in figure 1. They may for example be situated at a distance from the fold line FL22, FL24 such that the upper edges formed by said portions 11a, 13a will be situated at a distance from the longitudinal sides 20a, 20b of the rear wall panel 20.

An upper front corner portion of the respective side panel 11 , 13 may be chamfered such that an upper front edge 11 b, 13b extending from the portion 11a, 13a towards said one or more bottom front rim panel 12a, 12b is formed. If there are first and second bottom locking tabs 17, 19, as will be discussed in detail below, present, the upper front edge 11b, 13b extends preferably towards the transversal outer edge of such first and second bottom locking tabs 17, 19. The chamfering of said comer may be shaped along a straight line, as exemplified in Figure 1. The chamfering may extend along a line of a different shape than the one disclosed in figure 1.
