Description

[0001] Recyclable packaging for a household appliance

[0002] FIELD OF THE INVENTION

[0003] The present invention relates to a recyclable packaging for a household appliance.

[0004] BACKGROUND OF THE INVENTION

[0005] Nowadays, household appliances before being installed on site, are typically stored and transported within suitable packaging arrangements which protect them from external impacts. Packaging process are generally realized by placing impact preventers to the lateral, lower, and upper sides of the household appliances. Said impact preventers are often made of expanded polystyrene (EPS) which has a rather limited recyclability. Afterwards, the EPS are wrapped by transparent nylons and the household appliances are placed into carton boxes and they are ready for transportation.

[0006] For example, CN 20426681 U discloses a packaging base for a refrigerator formed from an expanded polystyrene (EPS) supporting element and elastic cushioning elements. WO 2022 248 010 A1 discloses a packaging base on which a household appliance can be arranged. The packaging base includes a tray made of expanded polystyrene with cushioning elements adapted to at least partially bear the weight of the household appliance and to protect a bottom region of the household appliance from impacts.

[0007] SUMMARY OF THE INVENTION

[0008] It is an object of the invention to provide an environmentally friendly packaging for a household appliance capable of efficiently protecting the household appliance from external impacts or external pressure and efficiently bearing the said household appliance while providing protection against ground moisture. The object is solved by the subject-matter of the independent claim.

[0009] The present invention pertains to a recyclable packaging for a household appliance according to claim 1.

[0010] Preferred embodiments are subject of the dependent claims.

[0011] According to the invention, a recyclable packaging for a household appliance comprises a structural base configured to at least accommodate and secure the household appliance; a top configured to at least partially cover the household appliance; wherein the structural base and the top are configured to at least maintain in position at least two cardboard panels; wherein the at least two cardboard panels face each other at a fixed predefined distance and extend at least between the structural base and the top along a height; wherein the at least two cardboard panels comprise each at least a honeycomb layer that is configured to be folded to form at least a first edge region orthogonal to at least a lateral main side; wherein the at least one first edge region is configured to be located along a front side of the household appliance or along a back side of the household appliance, and the at least one lateral main side is configured to be located along a respective lateral side of the household appliance; wherein the at least one first edge region is configured to be at least once folded at least partially onto itself to form at least a reinforced corner part of the corresponding cardboard panel; the at least one reinforced corner part being configured to be located at a respective corner of the household appliance. Such configuration for recyclable packaging has the advantage of providing fewer packaging units with a reduced environmental impact while ensuring protection of the household appliance against potential external impacts and providing adequate mechanical strength for bearing the heavy load of the household appliance itself or heavy load on top of it. Indeed, on one hand, the honeycomb cardboard panels located on the sides and at corners of the household appliance provide corners and side protection against potential external impacts. On the other hand, the reinforced corner parts provide adequate mechanical strength for bearing the heavy load of the household appliance itself or for heavy load loaded on top of it using a simple folding process. In addition, only a top, a base and two cardboard panels are necessary to provide the aforementioned benefits, therefore minimizing the environmental impact and the step of packaging.

[0012] According to a further embodiment of the recyclable packaging, the at least one honeycomb layer is configured to be further folded to form at least a second edge region orthogonal to the at least one lateral main side; wherein the at least one second edge region is configured to be located along the back side of the household appliance or the front side of the household appliance in opposite position to the corresponding first edge region; where the at least one second edge region is configured to be at least once folded at least partially onto itself to form at least a reinforced corner part of the corresponding cardboard panel; the at least one reinforced corner part of the at least one second edge region being configured to be located at a respective corner of the household appliance. Additional reinforced corner parts provide additional mechanical strength for bearing the heavy load of the household appliance itself or for heavy load loaded on top of it. In addition, the similar folding process to form additional reinforced parts does not necessitate additional components or new steps, minimizing the environmental impact and ensuring a certain efficiency in the packaging process.

[0013] According to a further embodiment of the recyclable packaging, the at least one honeycomb layer comprises interconnected six-sided hollow chambers that are enclosed between two planar sheets extending between the structural base and the top; wherein the interconnected six-sided hollow chambers are arranged such that they extend orthogonally to the planar sheets. In general, interconnected six-sided hollow chambers exhibit the highest impact absorption when forces applied are perpendicular to the planar sheets. Therefore, with such configuration, the honeycomb structure ensure the highest impact absorption capacity against lateral, frontal, and rear pressures. Such orientation of honeycomb structure provides then a high level of protection for the household appliance surfaces or corners against lateral, frontal, and back pressures.

[0014] According to a further embodiment of the recyclable packaging, the at least one first edge region and the at least one second edge region are configured to be at least once folded at least partially onto themselves to form the corresponding reinforced corner parts which comprise a plurality of stacked layers orthogonal to the at least one lateral main side; wherein the plurality of stacked layers do not overlap the corresponding lateral main side and stop short of intersecting a plane containing the corresponding lateral main side so that each four corners of the recyclable packaging comprises a stepped edge that aligns with the orientation of the corresponding lateral main side. The first edge region and the second edge region are strategically folded to serve at least two crucial purposes:

[0015] - they provide robust mechanical support for bearing the heavy load of the household appliance itself or for any heavy loaded on top of it; and

[0016] - the folding technique aligns the internal honeycomb structure in an optimal orientation, maximizing the cardboard panels' ability to absorb impacts from both frontal and rear pressures. This could be particularly critical for vulnerable elements protruding from the sides the household appliance.

[0017] According to a further embodiment of the recyclable packaging, at least a first elongated element with a quadrilateral prismatic shape extends between the structural base and the top and is located at one of the four corners of the recyclable packaging such that the at least one first elongated element is arranged as a lateral extension of the at least one lateral main side and in orthogonal contact with the corresponding plurality of stacked layers to at least partially fill a recess formed by the corresponding stepped edge; wherein the at least one first elongated element comprises a wood slat or an elongated piece of honeycomb cardboard at least inserted into the structural base (10) or fixed to at least the corresponding cardboard panel or to the structural base. Such additional elongated structure comprising a wooden slat or a honeycomb cardboard provides additional mechanical support for the heavy load of the household appliance itself or for heavy load on top of it. In other words, such vertical elongated element help to improve the load-bearing capacity of the packaging by taking some of the top-down pressure when the packaging is loaded on top of other loads or when additional items are placed on top of it. In addition of acting as a load distributor, such first elongated element give additional protection against lateral impacts. According to a further embodiment of the recyclable packaging, the structural base shows a quadrilateral prismatic shape and comprises at least a polypropylene tray comprising a bottom and four peripheral lateral walls rising orthogonally from the bottom. Such polypropylene tray is light-weighted, recyclable, and provides protection to the household appliance and cardboard material especially against ground moisture and potential water damages.

[0018] According to a further embodiment of the recyclable packaging, the structural base comprises at least a honeycomb cardboard panel on which the household appliance can be loaded and maintained safely; wherein the at least one honeycomb cardboard panel comprises a honeycomb structure that includes interconnected six-sided hollow chambers enclosed between two planar sheets and extending orthogonally to the two planar sheets; wherein the honeycomb structure is at least in a predefined region compressed up to at least a predefined depth of a total thickness of the at least one honeycomb cardboard panel to form at least one depression. The configuration of such additional components in the structural base ensures a stability of the household appliance by conforming the honeycomb cardboard panel to the specific contours of the household appliance bottom. In addition, the honeycomb cardboard material provides adequate mechanical strength to bear the heavy load of the household appliance and elasticity and plastically to compensate for minor and major impacts while being environmentally friendly and light-weighted. The panels of honeycomb cardboard can for example absorb the transmission of shocks to the household appliance, thus preventing any mechanical damage and failure of the household appliance, in particular during handling and transport of the household appliance.

[0019] According to a further embodiment, the recyclable packaging further comprises at least a second elongated element extending orthogonally to the at least one lateral main side and at least between the at least one first edge region or the at least one second edge region of the at least two cardboard panels; wherein the at least one second elongated element is at least partially arranged into at least a groove formed partially in the at least one first edge region and / or in the at least one second edge region; and wherein the at least one second elongated element comprises a wood slat or an elongated piece of honeycomb cardboard. Such second elongated element comprising a wood slat or an elongated piece of honeycomb cardboard provides additional structural strength and protection during transport and storage. In particular, such horizontal elongated elements help to stiffen the sides of the packaging, preventing them from moving, twisting, or bending. This is important in protecting against lateral pressure or impact. They distribute the pressure evenly over the entire surface of the packaging, reducing the possibility of damage at certain points of the packaging that would otherwise be more exposed to pressure or impact.

[0020] According to a further embodiment of the recyclable packaging, the top covers at least partially the at least two cardboard panels so that they are interlocked with each other by complementary of shape; wherein the at least two cardboard panels are at least embedded by complementary of shape or fixed to the structural base. The top securely holds the cardboard panels in place through a simple yet effective interlocking mean. Similarly, the structural base firmly anchors the cardboard panels by embedding or fixing the cardboard in the said structural base. Such configuration ensures that all components work in harmony, creating a stable and secure packaging structure without the need for complex assembly processes or additional fixing means to maintain together the main components of the recyclable packaging.

[0021] According to a further embodiment of the recyclable packaging, for each end of the at least one reinforced corner part located the closest to the top, at least a first protrusion is provided and extends from the plurality of stacked layers toward the top; wherein the top with a quadrilateral prismatic shape comprises at each of four corners at least a first recess that extends such that the at least one first protrusion in the at least one reinforced corner part is embedded in and maintained by the at least one first recess; wherein for each edges of the lateral main side located the closest to the top, at least a second protrusion is arranged and is configured to be embedded in and maintained by at least a second recess formed on a second edge of the top; the second edge of the top being parallel to the lateral main side. Such complementary of shapes between the top, the elongated elements, the lateral main sides and the reinforced corner parts of the cardboard panels ensures that all components work in harmony, creating a stable and secure packaging structure by simple interlocking mean without the need for complex assembly processes or additional fixing means. According to a further embodiment of the recyclable packaging, the top comprises at least a central region with a predefined length and width comprising a honeycomb structure; wherein the honeycomb structure comprises interconnected six-sided hollow chambers enclosed between two planar sheets and extending orthogonally to the two planar sheets; wherein the honeycomb structure is at least in one predefined part of the central region, compressed up to at least a predefined depth of a total thickness of the top to form at least an internal depression. With such configuration, the top is configured to also serve as an additional compartment for the transport of additional components such as instructions, accessories that are installed by the end customer, besides its protective function against impacts or pressure.

[0022] According to a further embodiment, the recyclable packaging further comprises a cardboard cover with a quadrilateral prismatic shape that is configured to enclose at least partially and maintain the top with the at least two cardboard panels; wherein the cardboard cover comprises a main side configured to cover the top and four peripheral walls extending orthogonally from the main side such that a first peripheral wall facing a second peripheral wall are configured to cover each partially a respective lateral main side, a third peripheral wall facing a fourth peripheral wall are configured to cover each partially one of the at least reinforced corner part of the at least two cardboard panels. Such cardboard cover provides additional protection against impacts and pressure while ensuring that the different components such as the top and the two cardboard panels are maintained safely together.

[0030] Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that a variety of alternate and / or equivalent implementations may be substituted for the specific embodiments shown and described without departing from the scope of the present invention. Generally, this application is intended to cover any adaptations or variations of the specific embodiments discussed herein.

[0031] Fig. 1 shows a recyclable packaging 100 for a household appliance (not represented in Fig. 1) comprising four first elongated elements 70, 72, 80, 82 and a second elongated element 74 according to an embodiment of the invention. In Fig. 1, the recyclable packaging 100 may be used for packaging a dishwasher. The recyclable packaging 100 may also be used for other household appliance such as refrigerator, cooker, washing machine, tumble-dryer, or microwave and modify based on the requirements of the specific household appliance. In Fig. 1, the recyclable packaging 100 comprises a structural base 10 configured to accommodate and secure the household appliance; a top 20 configured at least to cover the household appliance. The structural base 10 and the top 20 are configured to at least maintained in position two cardboard panels 30, 50. The two cardboard panels 30, 50 faces each other at a fixed predefined distance and extend at least between the structural base 10 and the top 20 along a height H.

[0032] In Fig. 1, the two cardboard panels 30, 50 comprise each at least a honeycomb layer 32, 52. Each honeycomb layer 32, 52 is then configured to be folded to form a lateral main side 38, 58 a first edge region 34, 54 and a second edge region 36, 56 such that the lateral main side 38, 58 is orthogonal to the first edge region 34, 54 and to the second edge region 36, 56. The first edge region 34, 54 of each honeycomb layer 32, 52 is configured to be located in front of the household appliance and the second edge region 36, 56 of each honeycomb layer 32, 52 is configured to be located in the back of the household appliance whereas the lateral main side 38, 58 of each honeycomb layer 32, 52 is configured to be located along a respective lateral side of the household appliance. The first edge regions 34, 54 and the second edge regions 36, 56 of the two honeycomb layers 32, 52 are configured here to be folded two times to form four reinforced corner parts 40, 42, 60, 62 configured to be located at four corners of the household appliance. Thus, the recyclable packaging 100 surrounds the household appliance on four different sides. In another embodiment (not illustrated here), each of the at least honeycomb layer may be configured to be folded to form one edge region orthogonal to a lateral main side. The edge region of the first honeycomb layer can be configured then to be located in the front or in the back of the household appliance whereas the edge region of the second honeycomb layer can be configured to be located in front or in the back of the household appliance, in opposite or similar position that the edge region of the first honeycomb layer. Each edge region may be then configured to be at least once folded to form one reinforced corner part configured to be located at two corners of the household appliance.

[0033] The height H of the cardboard panels 30, 50 which is defined as the length extending between the structural base 10 and the top 20 may be determined by the type of household appliance that is packed. Similarly, the width of the lateral main sides 38, 58 may be determined by the type of household appliance that is packed. The thickness of the two cardboard panels 30, 50 may be mainly defined by the honeycomb layers 32, 52 which can have a thickness between 10 mm and 50 mm, preferably of 20 mm. Regarding the first edge regions 34, 54 and the second edge regions 36, 56, which are configured here to be folded two times to form the four reinforced corner parts 40, 42, 60, 62, their width may be preferably below 200 mm and may be adapted depending of the type of household appliance.

[0034] In Fig. 1, at each four reinforced corner parts 40, 42, 60, 62, three stacked layers 34a, 34b, 34c; 54a, 54b, 54c; 36a, 36b, 36c; 56a, 56b, 56c are then formed from the folding. The number of stacked layers may be adjusted above or below three, depending on the specific protection requirements of the household appliance. Each plurality of stacked layers 34a, 34b, 34c; 54a, 54b, 54c; 36a, 36b, 36c; 56a, 56b, 56c do not overlap the respective lateral main side 38, 58 and stop short of intersecting a plane containing the respective lateral main sides 38, 58 so that each four corners of the recyclable packaging 100 comprises a stepped edge 44a, 46a, 64a, 66a that aligns with the orientation of the respective lateral main side 38, 58.

[0035] In details, the formation of the stacked layers by folding a honeycomb layer comprises a first step of partial cutting and a second step of folding. The honeycomb layer may comprise interconnected six-sided hollow chambers (e.g. the honeycomb) that are enclosed between two planar sheets and arranged orthogonally to the planar sheets. The two planar sheets may, for example, correspond respectively to the external surface and internal surface of the cardboard panels in Fig. 1 -3. From a honeycomb layer, one of two the planar sheet and eventually the interconnected six-sided hollow chambers may be cut along a straight line to form a weakness. The honeycomb layer may be then folded along the weakness once to form, for example, two stacked layers. This results into two layers stacked on each other and comprising each interconnected six-sided hollow chambers enclosed between two planar sheets parallel between each other. The number of stacked layers is not limited to two and could be increase depending on the protection requirement for the household appliance.

[0036] In Fig. 1, at each four corners of the recyclable packaging (100), a first elongated element 70, 72, 80, 82 with a rectangular prismatic shape extend between the structural base 10 and the top 20. In Fig. 1, four elongated elements 70, 72, 80, 82 are arranged at a respective corner of the recyclable packaging (100) but the number of elongated elements may be adjusted above or below four depending on the specific protection requirements of the household appliance. The first elongated elements 70, 72, 80, 82 are orthogonally in contact with the respective three stacked layers 34a, 34b, 34c; 54a, 54b, 54c; 36a, 36b, 36c; 56a, 56b, 56c and are a lateral extension of the respective lateral main side 38, 58. In other words, the height of the first elongated elements 70, 72, 80, 82 extends at least between the top 20 and the structural base 10 while each base of the first elongated elements 70, 72, 80, 82 is orthogonal to the direction of the respective three stacked layers 34a, 34b, 34c; 54a, 54b, 54c; 36a, 36b, 36c; 56a, 56b, 56c. In Fig. 1, the stepped edge 44a, 46a, 64a, 66a of each four corners of the recyclable packaging 100 is then evened out by inserting one of each first elongated elements 70, 72, 80, 82 in a respective recess 44b, 46b, 64b, 66b (recess not visible here, see Fig. 2) formed by the stepped edge 44a, 46a, 64a, 66a, resulting in an almost seemingly flat edge.

[0037] Each elongated element 70, 72, 80, 82 may comprise a wood slat or an elongated piece of honeycomb cardboard that may be fixed to the cardboard panels 30, 50 by an adhesive mean such as a glue. Each elongated element 70, 72, 80, 82 may also be bonded to the cardboard panels 30, 50 or to the structural base 10 by being inserted into dedicated grooves located at least in the respective cardboard panel 30, 50 or in the structural base 10. For example, the elongated elements 70, 72, 80, 82 may show at least one protrusion that could be inserted and maintained into dedicated grooves located at least in the respective cardboard panel 30, 50 or in the structural base 10. The wood slat or the elongated piece of honeycomb cardboard acts as load distributor while providing addition protection against external lateral impacts. Such elongated piece of honeycomb cardboard may comprise interconnected six-sided hollow chambers that are enclosed between two planar sheets and are arranged such that they extend orthogonally to the planar sheets. The orientation of the interconnected six-sided hollow chambers may be such that the interconnected six-sided hollow chambers extend orthogonally to the respective lateral main side 38, 58. Such orientation of the interconnected six-sided hollow chambers ensures the highest impact absorption capacity against lateral pressure. The wood slat may be selected from a group comprising: plywood, particleboard and mediumdensity fibreboard made of wood fibres with the addition of resin or synthetic glue, also called a medium-density fibreboard (MDF). The recommended thickness of the wood panel is preferably below 50 mm. In Fig. 1, a recess 48a, 68a is located along each of the three stacked layers 34a, 34b, 34c; 54a, 54b, 54c and extends from an internal edge 54h, 54i, 54j of the three stacked layers 34a, 34b, 34c; 54a, 54b, 54c parallel to the lateral main side 38, 58 toward the lateral main side 38, 58. Such recess 48a, 68a is close to the top 20 and may accommodate the contours of the household appliance or elements protruding from the sides of the household appliance. The occurrence of such recess as well as its dimensions, or location may be adapted to the type of household appliance. Two second recess 48b (see Fig. 4 for one of this recess) can also be arranged in the same way that the first recess 48a, 68a but along a back side of the household appliance. The two second recess 48b may be located along each of the three stacked layers 36a, 36b, 36c; 56a, 56b, 56c and may extend from an internal edge 36h, 36i, 36j (see Fig. 4) of the three stacked layers 36a, 36b, 36c; 56a, 56b, 56c parallel to the lateral main side 38, 58 toward the lateral main side 38, 58.

[0038] In Fig. 1, the second elongated element 74 with a rectangular prismatic shape is located in front of the household appliance. The said second elongated element 74 extends orthogonally to the lateral main sides 38, 58 between the two first edge regions 34, 54. In Fig. 1, the second elongated element 74 is located closer to the structural base 10 than the top 20 but may also be located closer to the top 20 than the structural base 10. The second elongated element 74 is at least partially arranged into two grooves 54d, 34d formed through the width of the stacked layers 54a, 34a. The second elongated element 74 may comprise a wood slat or an elongated piece of honeycomb cardboard. In Fig. 1, the grooves 54d, 34d are formed in one stacked layer 54a and 34a but may be formed through or partially through the width of one or more stacked layers. The second elongated element 74 has then a thickness similar to the honeycomb layers 30, 32 which is between 10 and 50 mm, preferably 20 mm. The width of the second elongated element 74 is preferably below 50 mm. The second elongated element 74 may or not extends up to the stepped edges 44a, 46a, 64a, 66a of the four corners of the recyclable packaging 100.

[0039] The number of second elongated element may decrease or increase. For example, at least one additional second elongated element may be provided along the front side of the household appliance and / or along the back side of the household appliance and may have similar configuration and / or dimensions that the second elongated element 74 in Fig. 1. For example, another second elongated element (not illustrated in Figs. 1 -4) may extend along a back side of the household appliance orthogonally to the lateral main sides 38, 58 and between the two second edge regions 36, 56. The said second elongated element may also be at least partially arranged into two grooves 36d (see Fig. 4) formed in the two second edge regions 36, 56. The two grooves 36d may be formed through the width of the respective staked layers 36a, 56a but can also be formed at least partially through the width of one or more stacked layers 36a, 36b, 36c and 56a, 56b, 56c. The said second elongated element may comprise a wood slat or an elongated piece of honeycomb cardboard as the second elongated element 74 in Fig. 1 located in front of the household appliance.

[0040] The top 20 may have a quadrilateral prismatic shape and may comprise at least a honeycomb cardboard panel including interconnected six-sided hollow chambers and two parallel planar sheets between which the interconnected six-sided hollow chambers extend orthogonally. The interconnected six-sided hollow chambers may be oriented vertically or, in other words, orthogonally to the top 20. With such optimal orientation, the honeycomb structure maximizes the ability of the top 20 to absorb impacts and vertical pressure.

[0041] In Fig. 1, the top 20 with a quadrilateral prismatic shape covers at least partially the two cardboard panels 30, 50 and is configured to at least maintain safely in position the two cardboard panels 30, 50 so that they may be interlocked with each other by complementary of shape. In details, for each extremity of the reinforced corner parts 40, 60, 42, 62 located the closest to the top 20, a protrusion 34e, 34f, 34g, 54e, 54f, 54g, 36e, 36f, 36g, 56e, 56f, 56g extends from each of the three stacked layers 34a, 34b, 34c; 54a, 54b, 54c; 36a, 36b, 36c; 56a, 56b, 56c toward the top 20. In Fig.1 , the protrusions 34e, 34f, 34g, 54e, 54f, 54g, 36e, 36f, 36g, 56e, 56f, 56g are in contact, aligned with each other and of the same shape generating one main protrusion that extends toward the top 20. In Fig. 1, each main protrusion is accommodated in one first recess 24a, 24b, 24c, 24d of the top 20 formed in one of four corners of the top 20. Two of the first recess 24a, 24b, extend from a first edge 20' of the top 20 that is orthogonal to the lateral main sides 38, 58 while two other first recess 24c, 24d extend from another first edge 20' of the top 20 that is also orthogonal to the lateral main sides 38, 58. In addition, four other recess 22a, 22b, 22c, 22d are also formed each at one of the four corners of the top 20. The other recess 22a, 22b, 22c, 22d are parallel to the first recess 24a, 24b, 24c, 24d and extend along either one of two second edges 20" of the top 20 that are parallel to the lateral main sides 38, 58 to accommodate the respective first elongated element 70, 72, 80, 82. In other words, the other recess 22a, 22b, 22c, 22d in the top 20 are an extension along the height H of the respective recess 44b, 46b, 64b, 66b that received the first elongated elements 70, 72, 80, 82. With such configuration, the reinforced corner parts 40, 60, 42, 62 are maintained safely in position by the top 20.

[0042] Furthermore, in Fig. 1, each of the lateral main side 38, 58 comprises a protrusion 38a, 58a arranged on a top edge which is the closest to the top 20. In Fig. 1, the protrusions 38a, 58a are arranged in the middle on the top edge of each lateral main side 38, 58 and extend toward the top 20. The protrusion 38a, 58a are embedded in and maintained by a respective recess 26a, 26b formed on the respective second edge 20" of the top 20. With such configuration, the lateral main sides 38, 58 are also maintained safely in position by the top 20.

[0043] In Fig. 1, the top 20 comprises also a central region 26 with a predefined length and width. The central region 26 is delimited in width by the occurrence of the stacked layers 34a, 34b, 34c; 54a, 54b, 54c; 36a, 36b, 36c; 56a, 56b, 56c while the length extends almost between the two edges 20' of the top 20. The predefined length and width of the a central region 26 may depend on the type of household appliance and associated accessories. The central region 26 may be made of at least a honeycomb cardboard panel that includes interconnected six-sided hollow chambers and two parallel planar sheets between which the interconnected six-sided hollow chambers extend orthogonally. In the central region 26, the honeycomb structure may be, at least in one predefined region, compressed up to at least one predefined depth of its total thickness to form at least one internal depression configured to store instructions or accessories of the household appliance. In details, the internal depression may be produced first by a die-cutting process to cut the internal planar sheet and then by a compression process to plastically deform the interconnected six-sided hollow chambers to the desire depth of the depression. The said depth of the depression may vary within the central region 26 up to 70%, ideally between 20% to 30% of the total height of the honeycomb layer, to adapt to the different accessories and instructions. In Fig. 1, the structural base 10 shows a quadrilateral prismatic shape and comprises a polypropylene tray 12 that provides protection against ground moisture or water damages for the household appliance and for additional honeycomb cardboard panels 14 comprised in the structural base 10. In Fig. 1, the polypropylene material 12 comprises a bottom and four peripheral lateral walls 12b, 12c rising vertically from the bottom. The four peripheral lateral walls may be configured to surround four sides of the household appliance and also the at least two cardboard panels 30, 50. The recommended thickness of the polypropylene sheet is between 1 mm and 5 mm, preferably 3 mm. In Fig. 1, the frontal peripheral wall 12b in front of the household appliance shows two recess 12f, 12g that are each adjacent to one of the reinforced corner parts 60, 40. Such recess is provided to facilitate the insertion of the household appliance on the structural base 10 using, for example, a forklift and avoid to damage the household appliance during the loading.

[0044] Furthermore, in Fig. 1, the structural base 10 includes at least one honeycomb cardboard panel 14. The honeycomb cardboard panel 14 may comprise interconnected six-sided hollow chambers enclosed between planar sheets and extending orthogonally to the planar sheets. The interconnected six-sided hollow chambers may extend orthogonally to the structural base 10. This orientation is adequate for efficiently bearing the heavy load of the household appliance and for absorbing the transmission of shocks to the household appliance, thus preventing any mechanical damage and failure of the household appliance.

[0045] In addition, the honeycomb structure may be compressed up to 70% of a total thickness of the honeycomb cardboard panel 14 in one or more predefined regions to form one or more depressions 14a, 14b. The location, the number, the size and the shape of the depressions may depend on the type of household appliance loaded to adequately accommodate the said household appliance. For example, in Fig.1 , two depressions 14a and 14b are formed enabling then to adequately loaded the household appliance when using a forklift. Depressions may also be formed to insert into it and adequately maintained the cardboard panels 30, 50 and eventually the first elongated elements 70, 72, 80, 82.

[0046] Depressions may be produced first by a die-cutting process to cut the planar sheet on an upper side of the honeycomb cardboard panel 14 and then by a compression process to plastically deform the interconnected six-sided hollow chambers to the desire depth of the depression. The said depth of the depression may vary within the honeycomb cardboard panel 14 up to 70%, ideally between 20% to 30% of the total height of the honeycomb cardboard panel 14, to adapt to the shape of the household appliance.

[0047] In Fig. 1, the two cardboard panels 30, 50 are also maintained safely by the structural base 10 such that the first edge regions 34, 54, the lateral main sides 38, 58, the second edge regions 36, 56 and the four elongated elements 70, 72, 80, 82 may be embedded in the honeycomb cardboard panel 14 along the four peripheral lateral walls 12b, 12c of the structural base 10. The first edge regions 34, 54 and the second edge regions 36, 56 may be embedded in the honeycomb cardboard panel 14 respectively along the front 12b and back walls of the structural base 10. The lateral main sides 38, 58 and the four elongated elements 70, 72, 80, 82 may be embedded in the honeycomb cardboard panel 14 along the two lateral walls 12c of the structural base 10.
