Description

The invention relates to a packaging insert for shock-absorbing arrangement of goods within a transport container, in particular within a folding box, according to the preamble of claim 1. Furthermore, the invention relates to a packaging system with such a packaging insert with the features of claim 9 and a method for fixing goods the packaging use of such a packaging system according to the features of claim 11.

The transport of loose as well as repackaged (sales packaging) goods usually takes place in suitable transport containers. These primarily serve to protect against loss as well as damage to the goods themselves as well as mutual damage. Folding boxes made of cardboard represent the primary, cheap and lightweight form of such transport containers. Companies commissioned with the transport of goods in particular require the use of cuboid folding boxes in order to be able to carry out largely automated logistical sorting and easy stacking.

The position within such a folding box is usually secured by adding loose fillers or using at least one packaging insert. While loose fillers are used to fill in the spaces remaining around the goods, a packaging insert carrying the goods is only supported in certain areas on the inside of the folding box. Overall, the packaging process of goods can be carried out more easily and quickly by using packaging inserts. In addition to using less material in terms of volume compared to loose fillers, packaging inserts consisting of a cardboard blank to be folded also require significantly less storage space when unfolded. Packaging inserts made of polystyrene (Styrofoam) are also known, but their unchangeable volume requires a correspondingly large amount of storage space and disposal that is separate from the folding box. Depending on the design of a packaging insert based on cardboard, a product carried by it can be positioned as it were floating within a folding box, which results in effective protection against damage from any deformations of the same.

From the DE 100 14 419 A1 a packaging insert is known with a blank which can be folded to form a hollow floor and which has wing walls which can be angled along fold lines and a frame and a wall section connecting the frame to a base plate. The frame and the base plate can be angled along fold lines relative to the wall section. On the frame is a for The membrane provided for receiving the goods that can be placed thereon is attached, which at least partially spans an opening delimited by the frame.

The blank is chosen so that the properly folded blank forms two contiguous hollow floors, each of which has a membrane. When using the packaging insert, the goods are placed on the membrane of one of the two connected hollow floors, while the other hollow floor is folded over along a fold line. As a result, the goods are fixed between the membranes of the two hollow floors, whereupon the packaging insert containing the goods can be arranged within a cardboard box.

Overall, the cutting requires a high degree of prefabrication with at the same time little flexibility in terms of use for differently shaped goods. This is essentially due to the size of the receiving area provided between the two membranes, which is already determined by the design. Due to the design, which inevitably has to be closely coordinated, the transport of goods with changing dimensions therefore requires the provision of various packaging inserts that are adapted to the respective goods.

The present invention is therefore based on the object of further developing a generic packaging insert in such a way that it allows the greatest possible flexibility with regard to the respective insert for goods of different sizes and shapes, despite simple handling. Furthermore, a method for fixing goods on a packaging insert of a packaging system is to be created.

According to the invention, this object is achieved in a packaging insert with the features of claim 1. The invention is also achieved by a packaging system with the features of claim 9. Advantageous configurations are the subject matter of the dependent subclaims 2 to 8 and 10.

The essence of the invention is the reduction to a single hollow floor, which can be wrapped with a separate film web after a product has been placed on its membrane. For this purpose, the invention proposes that the base plate has a free edge opposite the wall section with the frame arranged thereon. In the properly folded state of the blank, the free edge ensures the formation of a single, essentially plate-shaped hollow floor which does not have any interfering protrusions in a direction transverse to the free edge. In this way, the intended folded blank can be wrapped with a separate film web in the direction mentioned, so that the goods deposited on the membrane can be fixed between the membrane and a section of the film web.

The resulting advantage can be seen in the greatest possible flexibility with regard to the usability of the packaging insert for goods of different sizes. Since the properly folded blank does not provide for the integration of goods by folding them up, the shape and size of the goods to be packaged are not subject to any design-related constraints. In other words, the packaging insert according to the invention essentially forms a universally usable hollow bottom with a resilient membrane, which can be wrapped with a film web together with goods placed on the membrane, so that the goods are fixed between the hollow bottom and at least one section of the film web.

Compared to wrapping a membrane-free hollow floor with a film web, the invention enables a significantly safer transport of goods within a transport container, since this is arranged, for example, in the event of a fall in all directions, quasi-decoupled between the at least limited elastic membrane and the section of a likewise at least limited elastic film web . If the goods are arranged directly on a hollow floor without a membrane, they are sometimes exposed to the full resulting impact energy due to the lack of cushioning in the event of a fall, which increases the risk of damage to them many times over.

The membrane can be, for example, a section or a plate made of plastic. The membrane is preferably designed to be elastic at least to a limited extent in order to achieve the resilient effect that is advantageous for protecting a product. The membrane can be a foil act whose properties can correspond to those of the separate film web, for example.

According to a preferred development of the basic concept of the invention, the wing walls can be arranged on the frame. When the blank is folded as intended, the wing walls together with the wall section form an outer, in particular circumferential, wall of the hollow floor, which naturally extend between its base plate and the frame, which is spaced parallel to it together with the membrane. The wing walls arranged on the frame can be supported on the base plate via their edges lying opposite the associated fold lines. This allows the formation of a hollow floor, especially closed on all sides, with little use of material and little prefabrication, which provides enough space for the membrane, which is elastically displaced when a product is placed, so that it does not come into contact with the floor slab of the hollow floor either at rest or during a fall receive.

The packaging insert, which can be arranged via its base plate inside a transport container, is advantageously adapted to the internal dimensions of the transport container in terms of its dimensions in the longitudinal and transverse directions so that slipping parallel to the plane of the base plate is essentially excluded. The possible displacement of the packaging insert in a vertical direction of the transport container is counteracted according to the invention by the arrangement of wing supports. For this purpose, two such wing supports can preferably be attached to the base plate be arranged. The two wing supports are each arranged on one of two opposing edges of the base plate. Furthermore, the wing supports can be angled along fold lines extending at the end between the free edge and the wall section so that they can be supported on a corresponding inside of the transport container while bridging the free space above the goods. As a result, a displacement of the packaging insert arranged in a suitable transport container is largely or completely prevented, so that the goods can now be arranged in a floating manner within the transport container.

In order to further improve the handling of the packaging insert according to the invention, it is further proposed that the wing supports can each have a gripping opening. The gripping openings are designed in such a way that reaching through is possible in order to lift the entire packaging insert including the goods exclusively via the wing supports and, for example, lower it into a transport container. For this purpose, the gripping openings can be arranged in a particularly advantageous manner in the area of the edges of the wing supports facing away from the associated folding lines, which are supported on an inside of a closed transport container when the packaging insert is used as intended.

In order to increase the stability and the alignment of the individual sections of the blank to one another, it is provided that the base plate can have two slots, which are each located in the area of one of the folding lines provided for the bending of the wing supports. The slots are preferably aligned in such a way that their longitudinal direction extends parallel to the associated fold line. In contrast, two of the wing walls arranged on the frame and opposite one another can each have a tongue corresponding to one of the slots which, when the blank is folded as intended, each grip at least regionally into the associated slot. In this way, the position of the opposite wing walls of the frame, which are folded along their fold lines, is secured on the base plate so that they do not slip and can fold away in an uncontrolled manner, losing the space between the frame and the base plate, especially during a fall.

According to a preferred development, one of the wing walls arranged on the frame and opposite the wall section can have a foot section which can be angled along a fold line running parallel to the associated fold line. In this way, when the blank is folded as intended, this wing wall can be supported via its foot section on the base plate of the hollow floor.

In a continuation of this idea, the base plate can have at least one, preferably two, hinged tongue (s) located in the area of its free edge. An area separated from the rest of the base plate by at least two cuts or slots is located under a hinged tongue understood, which is thereby correspondingly decoupled movable. Particularly preferably, the cuts or slots can begin at the free edge of the base plate so that the folding tongue can be at least partially set up along an imaginary fold line running between the ends of the cuts or slots or an already provided fold line out of the plane of the base plate. The foot section of the wing wall arranged on the frame and opposite the wall section can then advantageously have at least one hole corresponding to the hinged tongue, into which the hinged tongue that is set up engages when the blank is folded as intended.

The folding tongue reaching into the hole creates a connection between the wing wall in question and the base plate, so that it cannot fold away in an uncontrolled manner, particularly during a fall. Of course, a reversal of the aforementioned with the same effect is also conceivable, in which the folding tongue (s) are arranged on the wing wall, while the at least one hole corresponding to this is arranged at a suitable location in the base plate.

According to the invention, the frame of the packaging insert can have extensions extending into its opening. These extensions are parts of the blank that are decoupled from the frame, for example via cuts or slits beginning at the edge, in such a way that these are along between the ends the cuts or slits extending imaginary fold lines or already provided fold lines out of the plane of the frame are at least partially elastically bendable or plastically angled. In particular, when a product is placed on the membrane, at least one of the extensions can thus support the limited immersion of the product in the hollow floor. It is conceivable that the membrane itself is connected to at least one of these extensions, so that the tension within the membrane increases accordingly with increasing deflection of an extension. Overall, the extensions support the formation of a trough shape when a product is placed on the membrane.

The packaging insert according to the invention now presented has an extremely high degree of flexibility with regard to its use for goods of different sizes and / or different shapes. Due to the combination of a prefabricated blank with a resilient membrane and a separate sheet of film, the packaging insert according to the invention can also be used for goods that are different from one another, since the area provided for receiving the goods, especially perpendicular to the plane of the membrane, is not subject to any design-related restrictions. Compared to two hollow floors each equipped with a membrane, goods of different heights can therefore also be packed.

The invention is also directed to a packaging system which comprises a packaging insert according to the invention as described above and a film web. The film web is at least partially included Goods can be wound between a section of the film web and the membrane of the packaging insert in a direction transverse to the free edge around the hollow bottom of the blank folded as intended.

The advantage resulting from this has already been explained in more detail in connection with the presentation of the packaging insert according to the invention, so that in order to avoid repetition, reference is made at this point to the corresponding explanations.

According to a preferred development of the packaging system according to the invention, it can contain a winding machine which is then used to wrap the hollow bottom with the film web.

Fig. 1 shows a perspective view of a blank 1, which with the formation of a packaging insert according to the invention, not yet visible here? (please refer Fig. 2 ) is designed to be foldable. The blank 1 comprises a base plate 2 and a frame 3, which are connected to one another via a wall section 4 integrated between them. The frame 3 itself delimits an opening 5, which is formed by a membrane 6 fastened to the frame 3 is overstretched. At the edges of the frame 3, individual wing walls 7-9 are arranged, which can be angled with respect to the frame 3 along folding lines F1-F3. Between the frame 3 and the wall section 4 as well as the base plate 2 and the wall section 4 there is also a fold line F4, F5 which run parallel to one another. The base plate 2 and the frame 3 can be angled relative to the wall section 4 via the folding lines F4, F5.

The base plate 2 has a free edge 2 a opposite the wall section 4 with the frame 3 arranged thereon, which in the present case has two folding tongues 10, 11. Each of these folding tongues 10, 11 is formed by cuts or slots beginning at the free edge 2a, through which the folding tongues 10, 11 are decoupled from the rest of the base plate 2. The wing wall 8 arranged on the frame 3 and opposite the wall section 4 has a foot section 8a which can be angled with respect to this wing wall 8 along a fold line F6 running parallel to the associated fold line F2. In the present case, the foot section 8a has two holes 10a, 11a which adjoin the fold line F2 and which correspond to the folding tongues 10, 11 of the base plate 2.

A wing support 12, 13 is arranged on the opposite edges of the base plate 2, each of which can be angled relative to the base plate 2 along a fold line F7, F8 extending at the end between the free edge 2a and the wall section 4. Looking at the lines between the F7, F8 and the Fold lines F7, F8 facing away from edges 12a, 13a extending height of the wing supports 12, 13, this is, in the present case in particular two to two and a half times greater than the parallel to this height of the two wing walls 7, 9. Each wing support 12, 13 has a and arranged in this for reaching through or around gripping openings 14, 15 which are each arranged in the area of the edges 12a, 13a of the wing supports 12, 13 facing away from the associated folding lines F7, F8. Furthermore, the base plate 2 has two slots 16, 17, which are each located in the area of the folding lines F7, F8 provided for angling the wing supports 12, 13, whereby they extend parallel to these. In contrast, the two of the wing walls 7, 9 arranged on the frame 3 and opposite one another each have a tongue 16a, 17a corresponding to one of these slots 16, 17.

Fig. 2 shows the result of the blank 1 folded in relation to the folding lines F1-F6 Fig. 1 to a packaging insert 100. For this purpose, the wing walls 7-9 were angled along their folding lines F1-F3 by 90 ° in the direction of the frame 3, the foot section 8a previously or subsequently also being angled along its folding line F6 by 90 ° in the direction of the frame 3. Then the frame 3 together with the wing walls 7-9 along the fold line F4 and the wall section 4 itself along the fold line F5 in each case in the direction of the base plate 2 with respect to the wall section 4 were angled by 90 °. In this way, a hollow floor 101 was formed, the wing walls 7-9 together with the wall section having an outer, in particular Form circumferential wall 102 of the hollow floor 101. The opposite wing walls 7, 9 are supported on the base plate 2 via their edges 7a, 9a opposite the associated folding lines F1, F3, while the wing wall 8 opposite the wall section 4 is supported on the base plate 2 via its foot section 8a, which now runs parallel to the base plate 2 is supported. The tongues 16a, 17a arranged on the edges 7a, 9a of the opposing wing walls 7, 9 grip at least in some areas into the associated slots 16, 17 arranged on the base plate 2, the folding tongues 10, 17, which are at least partially positioned out of the plane of the base plate 2. 11 engage in the holes 10a, 11a arranged on the foot section 8a of the wing wall 8.

It can also be seen in this illustration that the frame 3 has extensions 3a-3h which extend into its opening 5 and which can be angled with respect to the frame along folding lines F9-F16. The packaging insert 100 is now for receiving a product W (see FIG Fig. 3 ) prepared.

Fig. 3 illustrates the inclusion of a schematically illustrated product W, which was placed on the membrane 6 attached to the frame 3 for this purpose.

Fig. 4 shows a packaging system 200 according to the invention which comprises the packaging insert 100 and a film web 201. As in Fig. 3 clearly shows, the goods W are still arranged on the membrane 6 of the frame 3 and now located under the film web 201. Specifically, the goods W are now enclosed between a section of the film web 201 and the membrane 6 of the packaging insert 100. For this purpose, the hollow floor 101 was wrapped with the film web 201 in a direction running transversely to the free edge 2a. In other words, the hollow floor 101 together with the goods W was wrapped with the film web 201 between the two wing supports 12, 13 so that the direction of the wrapping runs parallel between the opposite wing walls 7, 9. The wrapping of the film web 201 is preferably carried out with a wrapping machine belonging to the packaging system 200 and not shown here.

The packaging insert 100 equipped with the film web 201 to fix the goods W can be transferred in a manner not shown in a suitable transport container not shown here, which can preferably be a folding box made of cardboard. For this purpose, the two wing supports 12, 13 are previously angled along their folding lines F7, F8 by 90 ° towards the goods W, their gripping openings 14, 15 being used for easy lifting and lowering and ensuring a seat that is as free as possible from slipping within a transport container.
