Description

[0001] One aspect of the invention relates to a household appliance packaging with a paper-based wall. Another aspect of the invention relates to a household appliance system. This system comprises at least one household appliance and a household appliance packaging.

[0002] Paper-based packaging typically requires different layers to be joined together using adhesive or metal staples. This requires different materials than paper, requiring individual manufacturing steps. Furthermore, recycling such packaging requires a complex process, for example, to remove metal staples. With adhesive applied, this is even more difficult or sometimes even impossible. Therefore, such common household appliance packaging is also disadvantageous in terms of sustainability. Such non-monomaterial packaging, in particular, is disadvantageous in many aspects.

[0003] These existing solutions also have disadvantages when it comes to automating packaging production. The degree of automation is correspondingly limited.

[0004] Packaging can be made from a wide variety of materials. For example, packaging made from expanded polystyrene is common. However, packaging made from this material can be very stiff and bulky. Furthermore, packaging made from expanded polystyrene throughout has a disadvantage regarding its recyclability for environmental reasons. Furthermore, they also contain microplastics.

[0005] In this respect, paper-based packaging is more advantageous.

[0006] It is an object of the present invention to provide a household appliance packaging and a household appliance system in which a paper-based approach is possible in a way that saves foreign materials and yet provides appropriate functionality and stability of the packaging.

[0007] This object is achieved by a household appliance packaging and a household appliance system according to the independent claims.

[0008] One aspect of the invention relates to household appliance packaging with at least one paper-based wall. This, in particular only, paper-based wall is formed from a first layer that is designed with cavities. The paper-based wall is further formed by at least one second layer. The at least two layers are arranged relative to one another such that the wall formed thereby has at least two layers. One of the two layers has at least one hole and thus a continuous recess. The other layer has at least one integrated clamping tab that is movably arranged on this layer. The clamping tab is positioned in the region of the hole so that it can be inserted, in particular pressed, into the hole. When the clamping tab is pressed into the hole, a mechanical clamping connection is formed so that the two layers are held together, in particular only by the clamping connection.This creates a paper-based, in particular purely paper-based, household appliance packaging that does not require any foreign material, such as adhesive or metal staples, at least at the connection point between two layers. It is precisely this type of mechanically specific connection design, as embodied by the clamping connection described, that enables simple production, simple mechanical connection, and, in this respect, a very stable clamping connection, so that the at least two layers of this wall can be arranged in a very stable position relative to one another. Furthermore, such household appliance packaging can also be manufactured and formed in a highly automated manner. In particular, it is also easier and faster to produce manually than folding and gluing.

[0009] Paper-based packaging can be made entirely of paper or, for example, cardboard or carton.

[0010] By forming the clamping tab, which is also entirely paper-based, integrally in one of the two layers and thus in one piece with a single layer, the number of components in this wall of the packaging is generally minimized. This also saves manufacturing and assembly effort, as this integrated clamping tab does not have to be produced separately and subsequently mounted at a specific position.

[0011] In one embodiment, the clamping tab has a length that is greater than the thickness of the layer in which it is integrated. This allows the clamping tab to overlap with the layer in which the hole is formed when it is pressed in and thus in the final clamped state. In particular, the clamping tab can have a length such that, in the final pressed-in position, it also extends across the entire thickness of the layer in which the hole is formed. In particular, however, this clamping tab then does not protrude through the hole and protrude outwards on the opposite side.

[0012] The clamping tab can be positioned in various ways to achieve the clamping effect. This can be determined, in particular, by its length and its desired final position once the clamped connection is formed. For example, in the indented final position, the clamping tab can be oriented with its surface in which it spans perpendicular or essentially perpendicular to the plane in which the two layers are clamped. However, it is also possible for the clamping tab to be oriented obliquely to the plane in which the two layers are clamped in this indented final position.

[0013] In one embodiment, the clamping tab is designed as a free cut in the layer.

[0014] In one embodiment, the clamping tab is completely surrounded by the remaining material of this layer in the plane in which the layer is spanned. The clamping tab is therefore not an edge-side, outwardly projecting tab. Especially with such internal clamping tabs, such cutouts make it particularly easy to create and also precise with regard to the desired shape of the clamping tab.

[0015] In one embodiment, the other layer has an additional hole, which is at least partially congruent with the hole. The two layers are thus positioned relative to each other such that the hole and the additional hole overlap, at least partially. This makes it particularly easy to push the clamping tab out of this additional hole and into the hole in the layer.

[0016] In one embodiment, the additional hole is at least partially closed by the clamping tab in the unclamped state of the clamping tab, which is not pivoted. It is therefore possible for the clamping tab to completely cover the area of ​​this additional hole in this unclamped state. However, it is also possible for the clamping tab to be designed somewhat shorter in length, so that the additional hole is not completely covered by the clamping tab even in the unclamped state of the clamping tab. In this regard, these individual shapes of the clamping tab can be created by cutting free in this other position.

[0017] Depending on the respective geometry of the clamping tab, individual manufacturing steps for pivoting the clamping tab on the one hand and for accessing the hole via the additional hole on the other hand can be made possible even when the clamping tab is still in its basic state and is therefore not yet pivoted and pressed into the hole.

[0018] In one embodiment, the clamping tab has at least one integrated expansion part. In the unclamped state, this expansion part protrudes beyond the dimensions of the hole, particularly when viewed projected onto the layers. When the clamping tab is pressed into the hole, this expansion part expands at at least one edge of the hole, thereby increasing the clamping effect of the clamped connection. Such an expansion part is therefore designed as a projection that protrudes beyond at least one boundary edge of the hole when viewed projected onto the layers. The expansion part is, in particular, deformable. Especially when the clamping tab is preferably also paper-based or made of the same material as the other layer in which the clamping tab is integrally formed, a particularly strong clamping effect and thus a mechanically stable connection between the layers can be created.It is possible for the clamping tab to incorporate at least two separate expansion parts. These can be molded onto opposite side edges of the clamping tab. They can be formed as wing-like, particularly nose-like or wedge-like, lateral projections. By having at least two such expansion parts, which are formed particularly on opposite side edges of the clamping tab, a very uniform pressing and symmetrical fixing in the hole can be achieved. This supports a very advantageous clamping connection.

[0019] It is possible that at least one expansion part is designed locally as a lateral projection protruding from a side edge of the clamping tab.

[0020] In one embodiment, the second layer is also formed with cavities.

[0021] By designing the layers with cavities, they can be made thicker and, at the same time, more mechanically stable due to the structure. A single-layer, solid design of such a layer either increases the weight or lacks sufficient stability due to its very thin thickness. Such a structure with cavities enables a very lightweight layer, which, at the same time, is also mechanically very stable and relatively resistant to deformation.

[0022] The first layer may be corrugated cardboard or a sandwich-like layer. It may then have a honeycomb core or another type of core, for example. This core is preferably bounded on opposite sides by a cover layer, thus limiting the voids.

[0023] In one embodiment, the second layer may be a corrugated cardboard or a sandwich-like layer.

[0024] In one embodiment, the two layers are provided as separate components. However, in another embodiment, it is also possible for the at least two layers to be formed as a single-piece blank, which are connected and delimited by a defined bending line. The bending line is formed in a transition region where two adjacent edges of these layers are connected to each other.

[0025] In one embodiment, the household appliance packaging can be designed as a base plate. This means that it is intended for the household appliance to be packaged to be placed on this base plate.

[0026] In one exemplary embodiment, the base plate has a tray-like or box-like enclosure, in particular one made entirely of paper. The separate wall of the household appliance packaging is accommodated in this enclosure. In particular, in one exemplary embodiment, the base plate can have a plate-like base, in particular one made entirely of paper, which is accommodated in the separate enclosure. In one exemplary embodiment, the wall can be arranged on the separate base. This creates a multi-component, in particular one made entirely of paper, subunit that is intended for a very specific use in the packaging of a household appliance. In this respect, this base plate is then also designed to be mechanically very stable. In particular, the base plate is designed entirely of paper.

[0027] A further aspect of the invention relates to a household appliance system comprising at least one household appliance and comprising household appliance packaging according to the above-mentioned aspect or an advantageous embodiment thereof. In particular, the household appliance is packaged with this household appliance packaging.

[0028] Embodiments of the invention are explained in more detail below with reference to schematic drawings. They show: Fig. 1 shows a schematic representation of an embodiment of a household appliance system according to the invention with an embodiment of a household appliance and an embodiment of a household appliance packaging according to the invention; Fig. 2 shows a schematic representation of an embodiment of a household appliance packaging in a first manufacturing state; Fig. 3 shows the household appliance packaging in a subsequent intermediate manufacturing state; Fig. 4 shows the household appliance packaging according to Fig. 2 and Fig. 3 in the finished state of at least one paper-based wall of this household appliance packaging; Fig. 5 shows an exploded view of an embodiment of a household appliance packaging; and Fig. 6 shows a perspective view of an alternative of several layers of a wall of the household appliance packaging.

[0029] In the figures, identical or functionally identical elements are given the same reference numerals

[0030] In Fig. 1 a schematic perspective view of a household appliance system 1 is shown. The household appliance system 1 has at least one household appliance 2. The household appliance 2 can, for example, be designed for the care of laundry items. It can, for example, be a washing machine or a tumble dryer or a washer-dryer. However, the household appliance 2 can also, for example, be designed for cleaning dishes and can be a dishwasher. It is also possible for the household appliance 2 to be designed for storing and preserving food. In this regard, it can be, for example, a refrigerator or a freezer or a refrigerator-freezer combination appliance. It is also possible for the household appliance 2 to be designed for preparing food. It can, for example, be a cooking appliance. In this regard, it can be an oven or a microwave cooking appliance or a steam cooking appliance.

[0031] The household appliance system 1 further comprises a household appliance packaging 3. This can completely surround the household appliance 2 or only partially surround it. In the schematic representation in Fig. 1 The household appliance packaging 3 has at least one base plate 4. The household appliance 2 is placed on this base plate 4 when packaged. However, the household appliance packaging 3 can additionally or instead have further packaging parts that, for example, cover the household appliance 2 at least partially from the side and / or from the front and / or from the back and / or from above.

[0032] The household appliance packaging 3, in particular with regard to the base plate 4, is paper-based, in particular purely paper-based.

[0033] In Fig. 2 1 shows a schematic representation of an exemplary embodiment of a household appliance packaging 3. The household appliance packaging 3 has a wall 5 that is only paper-based. The paper-based wall 5 here has a first layer 6. In addition, the wall 5 in the exemplary embodiment has a further second layer 7. For example, the wall 5 can also have a third layer 8 and a fourth layer 9. The number of layers 6 to 9 is to be understood merely as an example, with a minimal configuration having at least a first layer 6 and a second layer 7.

[0034] Layers 6 to 9 shown here can be considered as individual, separate, plate-like, exclusively paper-based elements. However, it is also possible, as is also the case with Fig. 6 In another exemplary embodiment, it is explained that the layers 6 to 9 are provided as a one-piece blank. They can then be directly connected to one another by bending lines 10, 11 and 12 and bent towards one another around these bending lines 10 to 12 and thus also folded. The first layer 6 is formed with cavities. The first layer 6 can, for example, be corrugated cardboard or a sandwich panel. In one exemplary embodiment, a corresponding design can also be provided for at least the second panel 7. It is advantageous if the possible further layers 8 and 9 are also formed with such cavities.

[0035] A clamping tab 13 is formed in the first layer 6. The clamping tab 13 is formed in one piece and thus integrated with the first layer 6. It is therefore also made entirely of paper. The clamping tab 13 is bendable around a bending line 14. Otherwise, it is completely separated from the remaining area of ​​the first layer 6 by dividing lines 15, 16, and 17 and is thus cut free in this example.

[0036] The clamping tab 13 is formed locally in the first layer 6 such that, in the stacked and thus superimposed state with at least the second layer 7, in particular here in the example with all further stacked layers 7, 8 and 9, it is arranged at least partially congruent with holes 18, 19 and 20 formed therein. The holes 18 to 20 are, for example, angular, in particular square. By cutting free the clamping tab 13 in the first layer 6, there is Fig. 2 In the state of the wall 5 shown, an additional hole 21 is also formed, which is covered here by the clamping tab 13 that has not yet been pushed out, in particular completely covered. The length 22 of the clamping tab 13 is dimensioned in the exemplary embodiment such that the additional hole 21 is completely covered. However, it is also possible to cut the length 22 shorter, so that even in this still unassembled state of the wall 5, the additional hole 21 is at least partially exposed. In this Fig. 2 In the state shown, the clamping tab 13 therefore still extends completely in the plane in which the first layer 6 is also clamped.

[0037] Based on the Fig. 2 In the manufacturing state shown, layers 6 to 9 are stacked on top of each other in the exemplary embodiment, as shown in Fig. 3 Based on this in Fig. 3 In the state shown, the clamping tab 13 is then pressed downwards, as shown by the arrow P, and thus pressed into the holes 18, 19 and 20, in particular around the bending line 14. This then Fig. 4 The finished state of the wall 5 is shown. The clamping tab 13 then forms a clamping connection with the boundary edges of the holes 18, 19, and 20, so that clamping connections 23 and 24 are formed here.

[0038] The Fig. 4 The wall 5 shown in its final state is therefore manufactured entirely without paper, and the individual stacked layers 6 to 9 are held in position relative to one another only by the clamping connections 23 and 24. Therefore, no other connections using foreign materials, such as adhesive connections or staple connections, are formed.

[0039] In Fig. 5 An exploded view of an embodiment of a base plate 4 is shown, which may be an example of a household appliance packaging 3. This base plate 4 has, for example, three separate layers 6, 7, 8 that form a wall. It is also possible that these three layers 6, 7, 8 are again realized as a single-piece blank, as shown in Fig. 6 is shown in perspective.

[0040] In addition, the base plate 4 can have a plate-like base 25. In addition, the base plate 4 can have a separate, for example, tub-like or box-like enclosure 26. Preferably, both the base 25 and the enclosure 26 are each constructed exclusively from paper. In particular, the first layer 6 has at least one clamping tab 13 (not shown for clarity), preferably several clamping tabs 13, which are pressed into corresponding holes when the layers 6, 7, 8 are stacked on top of one another, as is shown in FIG. Fig. 2 bis Fig. 4 was explained schematically.

[0041] In Fig. 7 A further embodiment of the clamping bracket 13 is shown in a schematic plan view. This clamping bracket 13 has a base part 13a. Expanding parts 13b and 13c are integrally formed on the lateral edges of this base part 13a. This creates a wedge-shaped or trapezoidal clamping part or clamping bracket 13 that is widened in the width direction. Fig. 7 In contrast, a hole 18 of an underlying layer 7 is shown in a simplified manner and shown in dashed lines. As can be seen here, the clamping tab 13 extends, at least in the area of ​​the expansion parts 13b and 13c, over the extent and thus the clear width of the hole 18 measured in the width direction. When the clamping tab 13 is pressed into the hole 18 located underneath, these expansion parts 13b and 13c are deformed and the clamping effect is thus increased. The shape, number and location of these expansion parts 13b and 13c are to be understood merely as examples. In this regard, expansion parts formed locally in other ways, in particular on the side edges 13d and 13e of the clamping tab 13, can also be integrally formed. The expansion parts 13b and 13c can also extend over the entire length of the respective side edges 13d and 13e. Bezugszeichenliste
