Description

[0001] The invention relates to a packaging device, a stackable packaging system and a method for manufacturing a packaging device.

[0002] Styrofoam-based packaging devices for stackable packaging systems, for receiving and storing goods, particularly ventilation cooktops, are already known in the art. Due to precise manufacturing processes, styrofoam-based packaging devices exhibit low manufacturing tolerances, thus enabling stable fixation of the stored goods and stable retention of stacking support strips. Furthermore, cardboard-based packaging devices are also known in the art, but these, in contrast to styrofoam-based packaging devices, exhibit higher manufacturing tolerances. In particular, a stacking support strip can slip within a receiving unit designed to hold the stacking support strips, which presents a significantly high risk of stacking instability.

[0003] The object of the invention is, in particular but not limited to, providing a generic device with improved properties with regard to sustainability and / or safety. This object is achieved according to the invention by the features of claims 1, 9 and 10, while advantageous embodiments and further developments of the invention can be found in the dependent claims.

[0004] The invention relates to a packaging device for a stackable packaging system, with a cardboard-based frame unit for receiving a stored item, in particular a ventilation cooktop, and with at least one receiving unit arranged on the frame unit for receiving a stacking support bar for vertically stacking several packaging systems.

[0005] It is proposed that the at least one receiving unit include at least one clamping element to counteract movement of the stacking support bar within the at least one receiving unit.

[0006] This design allows for a particularly high level of safety when stacking packaging systems. Specifically, it enables a high degree of vertical stacking stability. Furthermore, it allows for minimal movement of a stacking support bar within a receiving unit, thereby reducing the risk of instability when stacking the packaging systems. Finally, it also enables a high level of sustainability, as the packaging device is made, at least in large part, from an environmentally friendly material.

[0007] A "packaging device" is understood to mean, in particular, a device for receiving and securing the stored goods within the device. The stored goods may be, for example, a household appliance or a part of a household appliance, such as a cooktop, especially a vented cooktop, or a cooktop element, or an oven door, or a control board, or another household appliance or part of a household appliance known to those skilled in the art. Preferably, the packaging device is designed to store the stored goods for an extended period of time, for example, several weeks, months, or years, and / or to transport the stored goods.

[0008] Preferably, the packaging device, in particular the frame unit, is designed to be placed in a storage container of the packaging system. Preferably, when several packaging systems are stacked vertically, one packaging system is positioned on top of a lower packaging system with respect to a stacking direction. The stacking direction is preferably designed to be at least substantially parallel to the Earth's gravity and, in particular, runs perpendicular to a base of the packaging device. Preferably, the frame unit, in particular its geometry and / or dimensions, is adapted to the storage container. In particular, the frame unit is designed such that it can be inserted and / or slid into the storage container by means of an interference fit or a form fit.Preferably, the frame unit is made of a cardboard-based material, for example, corrugated board or solid board. Preferably, the cardboard-based material has a thickness between 0.5 mm and 15 mm, advantageously between 2 mm and 10 mm, and more preferably between 3 mm and 5 mm. For example, the frame unit has outer surfaces oriented substantially perpendicular to one another in order to be advantageously inserted precisely and / or in a space-saving manner into cuboid storage containers, in particular standardized packaging cartons. Advantageously, the frame unit has at least one longitudinal beam and at least two crossbeams substantially perpendicular to it. Preferably, the frame unit has at least two substantially parallel longitudinal beams and at least two transverse beams substantially perpendicular to them. Preferably, the supports of the frame unit, in particular the longitudinal beams and the transverse beams, form the base of the packaging device.Preferably, the frame unit has a main extension plane that extends perpendicular to the stacking direction of the packaging system. Preferably, the base of the packaging device is oriented substantially parallel to the main extension plane of the frame unit. The frame unit is preferably manufactured by cutting and folding the cardboard-based material. Preferably, the frame unit has at least one recess for receiving the stored goods. Advantageously, the at least one recess of the frame unit can be manufactured by folding the cardboard-based material.

[0009] The term "essentially perpendicular" is intended here to define in particular an orientation of a direction relative to a reference direction, wherein the direction and the reference direction, in particular when considered in a projection plane, enclose an angle of 90° and the angle has a maximum deviation of in particular less than 8°, advantageously less than 5° and particularly advantageously less than 2°.

[0010] A "principal extension plane" of a building unit is understood to be, in particular, a plane which is parallel to a largest side face of a smallest imaginary cuboid which just completely encloses the building unit, and in particular passes through the center of the cuboid.

[0011] The at least one receiving unit is preferably mechanically connected to the frame unit. The phrase "mechanically connected" to the frame unit means, in particular, that the at least one receiving unit is advantageously connected to the frame unit by at least one frictional connection and / or at least one positive connection, for example, by riveting and / or snap-fit ​​connection and / or tongue-and-groove connection and / or clamping connection and / or another connection that would be considered useful by a person skilled in the art, and / or is materially bonded to the frame unit, for example, by a welding process, an adhesive bonding process, an injection molding process and / or another process that would be considered useful by a person skilled in the art, and / or preferably, that the at least one receiving unit is formed integrally with the frame unit.The at least one receiving unit preferably has an opening for receiving the stacking support strip. The at least one receiving unit is preferably designed to receive the stacking support strip in the stacking direction of the packaging system. In particular, a principal extension direction of the stacking support strip, when received in the receiving unit, is aligned at least substantially parallel to the stacking direction. The opening is designed to provide a precise fit for the stacking support strip. When manufactured from a cardboard-based material, the opening width of the receiving unit can have a manufacturing tolerance of up to 5 mm. Preferably, the at least one clamping element of the at least one receiving unit is designed to compensate for the manufacturing tolerance of the receiving unit and, in particular, to counteract movement of the stacking support strip within the receiving unit.

[0012] The term "principal extension direction" of an object is understood to mean, in particular, a direction that runs parallel to the longest edge of the smallest geometric cuboid that just completely encloses the object.

[0013] The at least one clamping element is preferably designed as a clamping tab made of a cardboard-based material, which is arranged, in particular, on an inner wall of the at least one receiving unit. Alternatively, the at least one clamping element is conceivable as an elastic clamping element made of foam, rubber, or silicone. Furthermore, it is conceivable as an alternative that the at least one clamping element is designed as a mechanical spring, such as a leaf spring or a compression spring. Another alternative is that the at least one clamping element is integrated within the at least one receiving unit as a wedge-shaped insert made of a cardboard-based, plastic-based, or wood-based material.

[0014] The term "intended" should be understood to mean, in particular, specially designed and / or equipped. The fact that an object is intended for a specific function should be understood to mean, in particular, that the object fulfills and / or performs this specific function in at least one application and / or operating state.

[0015] It is further proposed that at least one of the receiving units be made of a cardboard-based material, particularly one of the aforementioned materials. Such a design would enable a significantly higher level of sustainability. Furthermore, manufacturing costs can be kept advantageously low, as cardboard-based materials are less expensive compared to wood-based, metal-based, or plastic-based materials.

[0016] Furthermore, it is proposed that the at least one receiving unit, in particular the at least one clamping element, be formed integrally with the frame unit. Such a design allows for advantageously high manufacturing efficiency, since the at least one receiving unit can be manufactured together with the frame unit. Furthermore, additional connecting elements can be dispensed with, thus advantageously saving material and labor. Preferably, the at least one receiving unit and the frame unit can be manufactured from the cardboard-based material, particularly in one piece, using a common cutting and folding process.The term "one-piece" shall be understood to mean, in particular, at least materially bonded, for example by a welding process, an adhesive process, an injection molding process and / or another process that appears sensible to the person skilled in the art, and / or advantageously formed in one piece, such as by production from a single casting and / or by production in a single or multi-component injection molding process and advantageously from a single blank, in particular from a single cardboard-based sheet.

[0017] Furthermore, it is proposed that the at least one receiving unit includes a stabilizing element for stabilizing the stacking support strip, which projects at least partially beyond the frame unit, particularly along the stacking direction. Such a design provides advantageous protection, especially edge protection, for the frame unit. Furthermore, a guide can be provided for the advantageously guided insertion of a stacking support strip into the receiving unit. The at least one stabilizing element is preferably manufactured together with the receiving unit, the clamping element, and the frame unit by means of the cutting and folding process of the cardboard-based material. The at least one stabilizing element is preferably designed to counteract lateral tilting of the stacking support strip, particularly perpendicular to a force-alignment direction of the clamping element.The at least one stabilizing element preferably functions as a guide for inserting the stacking support strip. Preferably, the at least one stabilizing element projects between 0.1 cm and 10 cm, advantageously between 0.5 cm and 5 cm, and more preferably between 1.0 cm and 2.5 cm beyond the frame unit, particularly in the stacking direction.

[0018] It is further proposed that the at least one receiving unit, in particular the at least one stabilizing element, forms a corner profile of the frame unit. Such a design allows for advantageously simple manufacturing and / or construction, with the corner profile serving as an advantageous guide for receiving a stacking support strip.

[0019] Furthermore, it is proposed that the at least one clamping element be designed as a tab, which can be produced from the at least one receiving unit, particularly by means of a folding process. Such a design allows for advantageously high cost efficiency, as the clamping element can be produced in a single folding process together with the frame unit and the receiving unit. The at least one clamping element is preferably designed to exert a force on the at least one stacking support strip in order to press the at least one stacking support strip against an edge of the frame unit. Due to the folding process, the at least one clamping element preferably includes a fold that separates the clamping element from the rest of the receiving unit. The at least one clamping element preferably projects from the fold into the opening of the receiving unit.The at least one clamping element preferably has a maximum longitudinal extent perpendicular to the fold of the at least one clamping element of at least 3 cm, advantageously at least 5 cm, particularly preferably at least 7 cm, and more preferably at least 10 cm. The at least one clamping element preferably has a maximum longitudinal extent of at most one overall height of the frame unit. The overall height of the frame unit is preferably one maximum extent of the frame unit parallel to the stacking direction.

[0020] Furthermore, it is proposed that the clamping element has a folded edge, particularly the one mentioned above, which lies at least substantially at the same height, especially with respect to the stacking direction, as a terminal surface of the stabilizing element. Such a design allows for advantageously targeted force application by the clamping element. Furthermore, a portion of the clamping element can advantageously contribute to edge protection of the frame unit. Preferably, the terminal surface of the at least one stabilizing element is oriented at least substantially perpendicular to the stacking direction. Preferably, the terminal surface of the at least one stabilizing element extends beyond the frame unit with respect to the stacking direction.The requirement that the folding fold, in particular a main extension plane of the folding fold, of the at least one clamping element and the final surface of the at least one stabilizing element "lie at least substantially at the same height" is to be understood in this context in particular as meaning that a height of the folding fold relative to the stacking direction and a height of the final surface relative to the stacking direction differ from each other by less than 25%, preferably less than 10% and particularly preferably less than 5%.

[0021] It is further proposed that the folding edge of the at least one clamping element be arranged at least substantially parallel to a closing surface of the at least one stabilizing element, in particular the one mentioned above. Such a design enables advantageously uniform force transmission from the clamping element to the stacking support strip. "Substantially parallel" here refers in particular to an alignment of a direction relative to a reference direction, especially in a plane, wherein the direction has a deviation from the reference direction of, in particular, less than 8°, advantageously less than 5°, and most advantageously less than 2°.

[0022] Furthermore, a stackable packaging system, in particular the one mentioned above, is proposed, comprising at least one packaging device, in particular the one mentioned above, a storage container, in particular the one mentioned above, specifically for receiving the at least one packaging device, and at least one stacking support strip, in particular the one mentioned above. The stackable packaging system is characterized in particular by the advantageous properties that can be achieved through the features of the packaging device described above. For example, the storage container is designed as cardboard packaging, a box, or a crate. For example, the storage container is made of wood, plastic, or metal. Advantageously, the storage container is made of a cardboard-based material, such as corrugated board or solid board.Preferably, the storage container has a cuboid or cubic shape, which particularly facilitates easy vertical stacking. The at least one stacking support strip is made, for example, of plastic, metal, or cardboard. Preferably, the at least one stacking support strip is made of wood, particularly to ensure a high degree of durability. Preferably, the at least one stacking support strip has dimensions, in particular a cross-section and / or a length, that take into account the weight of the stored goods and the number of packaging systems to be stacked.

[0023] Furthermore, the invention relates to a method for manufacturing a packaging device, in particular one of the aforementioned types, wherein in at least one cutting step a cardboard-based material, for example a corrugated board or a solid board, is cut to size, wherein in at least one folding step the cut cardboard-based material is folded such that the cardboard-based material forms a frame unit, in particular one of the aforementioned types, for receiving a stored item, and wherein in an arrangement step at least one receiving unit, in particular one of the aforementioned types, for receiving a stacking support strip is arranged on the frame unit. It is proposed that in at least one process step a clamping element is arranged within the at least one receiving unit to counteract movement of the stacking support strip within the at least one receiving unit.The method for manufacturing the packaging device is characterized in particular by the advantageous properties that can be achieved through the features of the packaging device described above.

[0024] Preferably, the cutting step can be performed with a cutting tool, a punching tool, or another separating tool. Advantageously, in the at least one cutting step and the at least one folding step, the cardboard-based material is cut and folded such that the cut and folded cardboard-based material forms the frame unit and the at least one receiving unit together with the clamping element. Preferably, in the at least one process step, a part of the receiving unit is folded over to create the clamping element.

[0025] The packaging device, the packaging system, and the method for manufacturing the packaging device according to the invention are not intended to be limited to the application and embodiment described above. In particular, the packaging device, the packaging system, and the method for manufacturing the packaging device according to the invention may, to achieve a functionality described herein, comprise a different number of individual elements, components, units, and / or process steps than that specified herein.

[0026] Further advantages arise from the following drawing description. InThe drawings illustrate exemplary embodiments of the invention.

When stacking several packaging systems 12 vertically, one packaging system 12 is positioned on top of the one below it with respect to a stacking direction.

Specifically, the stacking support strips 18 are designed as square timbers. The length of the stacking support strips 18 is adapted to the height, in particular the internal height, of the storage container 30. Advantageously, the stacking support strips 18 have a dimension, in particular a cross-section and / or a length, which takes into account the weight of the stored goods and the number of packaging systems 12 to be stacked.

[0031] Packaging system 12 comprises a packaging device 10. Packaging system 12 also includes a further packaging device 28. The further packaging device 28 is identical in construction to packaging device 10, which is why only packaging device 10 will be described below. Packaging device 10 is designed to be placed in the storage container 30, in particular the bottom part, of packaging system 12. Packaging device 10 has a cardboard-based frame unit 14 for holding the stored goods, in particular a portion of the stored goods. In this case, the frame unit 14 is made of corrugated cardboard material. The corrugated cardboard material has a thickness between 3 mm and 5 mm, in particular 4 mm. The frame unit 14 has at least one recess 46 for holding the stored goods. The frame unit 14 has a support element 48.The frame unit 14 has a support element 50 for placing at least part of the stored goods. The frame unit 14 is U-shaped with a longitudinal beam and two crossbeams oriented essentially perpendicular to the longitudinal beam. The frame unit 14 has, in particular, outer surfaces oriented essentially perpendicular to each other, in order to be advantageously inserted precisely and / or in a space-saving manner into the cuboid storage container 30, preferably into the bottom part 42 of the storage container 30. The support element 48 forms an outer U-shaped profile. The support element 50 forms an inner U-shaped profile. In particular, the support element 50 has a lower overall height, especially with respect to the stacking direction, than the support element 48. The support element 50 is designed such that the stored goods do not protrude beyond the overall height of the frame unit 14.

[0032] The packaging device 10 has a receiving unit 16 arranged on the frame unit 14 for receiving the stacking support bar 18 for vertically stacking several packaging systems 12. The packaging device 10 has a further receiving unit 52 arranged on the frame unit 14 for receiving a further stacking support bar, in particular the four stacking support bars 18 of the packaging system 12 mentioned above, for vertically stacking several packaging systems 12. The receiving unit 16 is designed to receive the stacking support bar 18 in the stacking direction of the packaging system 12. In particular, a main extension direction of the stacking support bar 18, when received in the receiving unit 16, is aligned at least substantially parallel to the stacking direction.

[0033] The receiving unit 16 is made of a cardboard-based material. The receiving unit 16 is formed in one piece with the frame unit 14. The frame unit 14 can be manufactured by a cutting and folding process of the cardboard-based material. In this case, the frame unit 14 and the receiving unit 16 can be manufactured together by the cutting and folding process of the cardboard-based material. The receiving unit 16 has an opening 54 for receiving the stacking support strip 18. When manufactured from a cardboard-based material, the width of the opening 54 of the receiving unit 16 can have a manufacturing tolerance of up to 5 mm.

The receiving unit 16 comprises at least one clamping element 20 to counteract movement of the stacking support bar 18 within the receiving unit 16. The clamping element 20 is made of a cardboard-based material. The clamping element 20 is formed integrally with the receiving unit 16. In this case, the clamping element 20, together with the receiving unit 16 and the frame unit 14, can be manufactured by means of the cutting and folding process of the cardboard-based material. In this case, the clamping element 20 is designed as a flap, which can be produced from the receiving unit 16, in particular, by means of the folding process. The clamping element 20 is arranged at least substantially within the opening 54 of the receiving unit 16.The clamping element 20 is designed to exert a force on the stacking support strip 18 in order to press the stacking support strip 18 against an edge of the frame unit 14 and / or an inner wall of the receiving unit 16. The clamping element 20 of the receiving unit 16 is designed to compensate for the manufacturing tolerance of the receiving unit 16 and, in particular, to counteract the movement of the stacking support strip 18 within the receiving unit 16.

[0035] The receiving unit 16 includes a stabilizing element 22 for stabilizing the stacking support strip 18. The stabilizing element 22 projects at least partially beyond the frame unit 14 in the stacking direction. In this case, the stabilizing element 22 projects between 0.5 cm and 1.5 cm, in particular 1.0 cm, beyond the frame unit along the stacking direction. The stabilizing element 22 is formed integrally with the clamping element 20. The stabilizing element 22, together with the receiving unit 16, the clamping element 20, and the frame unit 14, can be manufactured using the cutting and folding process of the cardboard-based material. The stabilizing element 22 is designed to counteract lateral tilting of the stacking support strip 18, particularly perpendicular to a force direction applied by the clamping element 20. Furthermore, the stabilizing element 22 acts as a guide for inserting the stacking support strip 18 into the opening 54.

[0036] In this case, the receiving unit 16 is arranged at a corner edge of the frame unit 14. Specifically, the receiving unit 16 is located in a region where the base of the U-profile of the frame unit 14 abuts one of the legs of the U-profile of the frame unit 14. The receiving unit 16, and in particular the stabilizing element 22, forms a corner profile of the frame unit 14.
