Description

The invention relates to a padding part and a packaging arrangement for packaging an object.

Such upholstery parts are known in principle in the prior art, for. B. from the applicant's homepage. There, for example, molded fiber pads for dialysis products in the form of tubes are also known. These upholstery parts each have all the features of the preamble of claim 1. These upholstery parts each have two adjacent ribs which, starting from a common base area, each rise in a direction z perpendicular to the base area. The ribs each have an upper edge remote from the base surface with a straight longitudinal alignment. At their upper edges, the ribs each have a plurality of recesses for partially accommodating the objects to be packaged. The upholstery parts are preferably made as molded fiber parts from waste paper.

To produce a packaging arrangement according to the invention, two known padding parts of the same construction can be placed one on top of the other - folded over on one of their long sides - the recesses on the upper edges of the ribs of the two padding parts then partially encompassing the objects to be packaged. By enclosing the object in the two padding parts, the packaging arrangement formed by the stacking is stabilized at least against shearing forces with a component transverse to the longitudinal direction of the dialysis products to be packaged. On the other hand, the two folded-over padded parts are not stabilized relative to one another in the longitudinal direction of the objects to be packaged. Without the inserted objects to be packaged, the two cushion parts can be moved relative to one another.

The invention is based on the object of further developing a known padding part and a known packaging arrangement for packaging at least one object such that two padding parts, when they are arranged one above the other with ribs facing one another, are fixed relative to one another even without an inserted item to be packaged.

With regard to the upholstery part, this object is achieved by the subject matter of claim 1 . Accordingly, the upholstery part according to the invention is characterized in that at least one of the ribs has at least one first recess on its upper edge for partially encompassing a rib of another upholstery part. The gripping takes place in particular at the upper edge of the rib.

The first recess in the upper edge of at least one rib claimed for a first padding part is the prerequisite for the advantageous interlocking of the first padding part with another or second padding part in the packaging arrangement according to the invention, as described further below.

The claimed alignment of the ribs in direction z perpendicular to the base area of the upholstery part means that the ribs each extend at least with a component in the z-direction; however, they do not necessarily have to extend symmetrically in the z-direction. In this respect, ribs that are inclined to the base area also fall under this definition according to the invention.

According to a first exemplary embodiment of the upholstery part according to the invention, at least one of the upper edges of the ribs is straight, wavy, curved or kinked in at least one section.

A partial delimitation of the receiving space by the curved, corrugated or kinked section of at least one rib has the advantage that the object to be packaged can be stored more stably in the receiving space because it is then preferably supported at several points or areas. This applies in particular when the curvature, the corrugation or the crease is locally adapted as well as possible to the outer contour of the object to be packaged.

The claimed formation of a step on at least one of the opposite walls of two adjacent ribs advantageously serves to delimit the receiving space in the z-direction. The item to be packaged is advantageously supported in the z-direction by the step.

The accommodation space for at least partially accommodating the object to be packaged is basically, as claimed, formed between at least two adjacent or opposing ribs. To stabilize the object in the receiving space, at least one second recess can be provided as an alternative or in addition to the curvature, the corrugation or the kink in at least one of the adjacent ribs, in particular on its upper edge, for at least partially receiving and supporting the object to be packaged in a local limited area. The support is particularly effective when the inner contour of the second recess is adapted as locally as well as possible to complement the outer contour of the object to be packaged. The space left out by the second cutout of the respective rib is part of the receiving space.

The receiving space, possibly including the space cut out by the second cutout, is preferably designed in such a way that the object to be packaged can be stored therein without play, in order to effectively avoid damage during transport, particularly in the event of vibrations occurring.

If two or more objects are to be packaged with one or two cushion parts arranged one above the other, then several of the receiving spaces can be formed next to one another between the same adjacent ribs on the same cushion part.

If an object with linear length orientation, e.g. B. a tube or a rod, then the second recesses at the top edges of the ribs of the cushion part are aligned with each other along a straight line of alignment, i. H. the second recesses on different ribs of the same cushion part then align with each other. These recesses are then preferably formed on the upper edges of the ribs in such a way that their alignment lines form an acute angle α with the tangents or the longitudinal alignments of the upper edges of the ribs at the positions or in the area of the second recesses. The formation of said acute angle in turn contributes to the stabilization of the object within the receiving space against shear forces that occur.

In the case of upper edges of the ribs with a straight longitudinal orientation, the common base surface preferably has a straight reference line, for example a straight edge. The projections of the straight longitudinal alignments of the upper edges into the base are then aligned at an acute angle βi with βi>0° relative to the straight reference line.

The straight reference line can be a fictitious or real straight line on the base or a straight side edge of the base. Otherwise, the base area can be limited or contoured as desired. The at least one necessary straight reference line is needed to define the angle of inclination β of the ribs of the upholstery part. Preferably, the base is rectangular. The claimed acute angle of inclination βi with βi>0° advantageously allows--in particular with rectangular base areas of the upholstery parts--a crossing of the top edges of upholstery parts arranged one on top of the other with the resulting advantages, as described below.

The angles α and β can be equal.

A first plurality of the ribs can be provided on the cushion part, which extend from the upper side of the common circular surface in the +z direction and at the same time a second plurality of ribs can be provided which extend from the underside of the common base surface in the -z direction extend. More preferably, the ribs may be formed alternately on the top and bottom of the common base.

The object of the invention is achieved with regard to the packaging arrangement by the subject matter of claim 17. Accordingly, in the packaging arrangement according to the invention, the first and the second padding part are arranged one above the other in such a way that their respective ribs face each other and at least two of the facing ribs intersect at a crossing point, with the at least one first recess on the upper edge of at least one rib of the first cushion part is formed at the location of the crossing point and is engaged there with the facing upper edge of a rib of the second cushion part or optionally with the first recess in the facing upper edge of the rib of the second cushion part in the crossing point.

The inventive design of at least one first recess on at least one first cushion part offers the advantage that a second cushion part placed folded over the first cushion part engages with the first recess of the first cushion part, so that the two cushion parts arranged one above the other in the x-y plane the base are secured against shearing forces. That is, a relative movement of the two padding parts is no longer possible due to the interlocking according to the invention—even without an object to be packaged inserted between the padding parts. In the case of the packaging arrangement according to the invention, any shearing forces which occur on the packaging arrangement are advantageously absorbed by the cushioning parts which are arranged one above the other and which engage with one another via the first recesses. Due to the inventive interlocking of the two cushion parts, these shearing forces are advantageously no longer passed on to the object to be packaged, as was the case in the prior art when the two cushion parts were not in engagement with one another.

Otherwise, the advantages of this solution correspond to the advantages mentioned above with reference to the claimed upholstery part.

The terms “first/second” recess, “first/second” upholstery part, etc. are not primarily to be understood as numbers, but rather serve to distinguish between similar objects. However, a meaning as a numeral is also not excluded. The correct actual meaning results from the context of the sentence.

The first and second padding parts for forming the packaging arrangement according to the invention can, but by no means have to, be of identical construction.

Two padding parts are arranged one on top of the other to form the packaging arrangement according to the invention in such a way that the ribs of both padding parts face each other and cross at the crossing points. The crossing of the top edges of the ribs of the stacked pad parts is imperative in the present invention to achieve the desired interlocking of the two pad parts. The necessary crossing excludes a congruent arrangement of the upper edges facing each other, at least in the area of the crossing points. In order to realize the crossing, when the two upholstery parts are arranged one on top of the other - depending on their initial position relative to each other and depending on the design of the ribs on the base surfaces - in addition to a "turning over" or folding over, rotation of at least one of the two upholstery parts relative to the other upholstery part may be required.

As stated, in the packaging arrangement according to the invention, the first cushion part with the first recesses on the upper edges of its ribs engages with the upper edges of the ribs of the second cushion part. It is not absolutely necessary for this that first recesses are also formed on the upper edges of the ribs of the second cushion part in the crossing points. If this is the case, however, then in the packaging arrangement according to the invention the first recesses in the upper edges of the ribs of the first padding part engage the first recesses in the upper edges of the ribs of the second padding part in the crossing points. If the first recesses are formed not only on the first but also on the second padding part, this additionally increases the rigidity of the packaging arrangement with respect to shearing forces, even if these act on the packaging arrangement from different directions.

Typically, the item to be packaged is not completely but only partially accommodated by the receiving space of the first cushioning part or by the second recesses on the upper edges of the ribs of the first cushioning part, so that parts of the item to be packaged protrude beyond the first cushioning part. In these cases it is necessary that with the packaging arrangement according to the invention, i. H. when the first and second padding parts are arranged one on top of the other, the receiving spaces of the two padding parts face each other and/or the second recesses on the upper edges of the ribs of the two padding parts face each other for the complete accommodation of the item to be packaged between the two padding parts. Conversely, if the receiving spaces and/or the second recesses of the first padding part are designed in such a way that they completely receive the item to be packaged without it protruding upwards, then no receiving spaces or second recesses need to be provided on the second cushioning part or If they are provided, they do not necessarily have to face the receiving spaces or second recesses on the first cushion part.

Preferably, the first recess is complementary as much as possible, i. H. for an accommodation with as little play as possible, adapted to the outer contour of the upper edge of the rib of the second cushion part to be accommodated at the crossing point. It is advantageous for this if the first recess in the upper edge of the rib of the first cushion part is aligned in the direction of a tangent to the upper edge of a rib of the second cushion part at the crossing point; and that - if present - the first recess in the upper edge of a rib of the second cushion part is aligned in the direction of a tangent to the upper edge of the rib of the first cushion part at the crossing point.

The provision of a container, for example in the form of an outer carton or a crate, is also not absolutely necessary for the packaging arrangement according to the invention. In particular, it is not absolutely necessary when a plurality of packaging arrangements are arranged one on top of the other, preferably with objects to be packaged placed in between.

Nevertheless, the packaging arrangement according to the invention can, of course, comprise a container into which the first and second padding parts, which are arranged one above the other and are in engagement with one another, are inserted. The object to be packaged is then advantageously located between the two padding parts arranged one above the other and is there, as described, well protected against external forces. The canister provides additional protection against these forces.

Preferably, the external dimensions of the first and second upholstery parts, which are arranged one above the other and are in engagement with one another, correspond at least at certain points, i. H. preferably at at least two points, the inside dimensions of the container. In this way it is ensured that the padding parts arranged one above the other with the object to be packaged located in between do not slip inside the container.

Further advantageous configurations of the padding part according to the invention and the packaging arrangement according to the invention are the subject matter of the dependent claims.

The invention is described in detail below with reference to the figures mentioned in the form of exemplary embodiments. The same technical elements are denoted by the same reference symbols in all figures.

1 shows the padding part 100 according to the invention for packaging at least one object (in 1 Not shown).

The upholstery part 100 consists of a plurality of adjacent interconnected ribs 110-i with i=1-I, here with I=4. The ribs rise—starting from a common base area 120—each in a direction z perpendicular to the base area. The base 120 is here, for example, rectangular in shape with at least one straight edge as a reference line 122. The ribs each form an upper edge 112 remote from the base, each with a straight longitudinal alignment L. The projections 112' of the straight longitudinal alignments L on the upper edges 112 of the ribs 110 -i in the base area 120 are each aligned inclined by an acute angle βi>0° with respect to the straight reference line 122 on the base area. The projection is in 1 drawn as a dot-dash line parallel to the longitudinal direction L.

The upholstery parts 100 according to the invention are each made as molded fiber parts, preferably made from waste paper.

A first recess 114 can be seen on the upper edges 112 of at least some of the ribs 110-i for partially encompassing the ribs, in particular their upper edges, by another or second cushion part; please refer 3 , 4 , 6 and 8th .

The first recess 114 is aligned obliquely with respect to the longitudinal alignment L of the upper edge 112 .

In 1 it can also be seen that the ribs 110-i on their upper edges 112 have, in addition to the first recess 114 for partially encompassing the upper edges of the ribs of the second padding part, also optionally at least one second recess 116 for at least partially accommodating an object 20 to be packaged; please refer 3 , 4 , 5 , 7 and 9 .

When the item to be packaged 20 is elongated and straight, i. H. is tubular, then the second recesses 116 on the upper edges 112 of different ribs 110-i of the cushion part 100 can be aligned with one another along a straight alignment line FL, i. H. the second recesses are then aligned with one another. Preferably, but not absolutely necessary, the vanishing line FL then forms an acute angle α with the straight longitudinal alignment of the upper edges 112 of the ribs 110-i. This applies in particular when a projection of the vanishing line FL in the common base area 120 forms a right angle with the straight reference line on 122 of the base area 120 . In exceptional cases, the angles α and β can be the same.

The first and second recesses 114, 116 on the same upper edge 112 of a rib 110-i can be of different sizes and/or different shapes. This typically results from the different functions that are assigned to the two recesses. As mentioned above, the first recess 114 serves to at least partially encompass the ribs of a second padding part, while the second recesses 116 serve to at least partially accommodate the article to be packaged.

2 illustrates a second embodiment of the padding according to the invention. A first plurality of ribs 110 is provided extending from the top of the common base 120 in the +z direction and a second plurality of ribs 110'' is provided extending from the underside of the common base 120 in the - z. All ribs here have a straight longitudinal alignment L.

The ribs 110 of the first plurality and the ribs 110" of the second plurality may, as in 2 shown, may be formed alternately on the common base. If the top edges of the ribs are parallel to one another, then they alternate with one another in a direction transverse to their top edge. If the ribs or their upper edges are aligned in parallel, the angles of inclination β i >0° assigned to them relative to the straight reference line 122 are the same in each case. However, in accordance with the present invention, the angles βi of the top edges of the ribs of a pad need not all be the same; rather, they can also be different. In the latter case, the ribs are not parallel to each other. What is decisive, however, is that the angles βi are each greater than 0°, preferably: 20°<β<60°, more preferably 29°<β<40°. This applies both to the first exemplary embodiment according to FIG 1 , in which the ribs on the common base 120 only extend in the +z-direction, as well as for the second exemplary embodiment according to FIG 2 .

With regard to the second exemplary embodiment, it should also be mentioned that the first and/or the second recesses 114, 116 on the upper edges of the ribs on the upper side and on the underside of the base area 120 can be formed in such a way that their vanishing lines FL are parallel to one another, preferably one above the other or .

The second embodiment of the cushion part according to 2 offers the advantage that if the second recesses 116 on the ribs on the upper side and the ribs on the lower side are formed with unequal shapes, then different sized and differently shaped objects can be packed with the same padding part, as is shown in 4 is shown. To pack the objects 20 of different sizes, it is then only necessary to “turn over” the two cushion parts once by 180° so that the second recesses that match each other for the object to be packed are opposite each other.

For the two embodiments of the upholstery part according to the invention, at least some of the ribs 110, 110" taper in the +z or -z direction. The tapering design of the ribs offers the advantage of improved stackability of the individual upholstery parts - without turning them over - into one another This applies in particular when the ribs of the upholstery parts are each designed as hollow bodies.

According to a further exemplary embodiment, the upper edges 112 of at least some of the ribs, preferably of all ribs 110, 110'', can be of the same height in the +z and/or in the -z direction.

To accommodate a plurality of objects to be packaged, a plurality of second cutouts 116 can also be provided next to one another on the upper edges 112 of the ribs 110-i of a padding part. These second recesses are then preferably each adapted to the outer contours of the objects to be packaged. If the objects to be packaged have the same shape on the outside, then the second recesses arranged next to one another can also have the same shape. Conversely, if the objects to be packaged are of different sizes or shapes, then the second recesses 116 are also to be designed with different sizes and/or different shapes, as mentioned, in each case adapted to the outer contours of the objects to be packaged.

3 shows a packaging arrangement 150 according to the invention in which a first padding part 100 and a second padding part 100" are "folded over", ie are arranged one above the other with ribs 110, 110" facing one another. The first and the second upholstery part are here, for example, identical in construction. Identical construction is by no means mandatory for the upholstery parts arranged one on top of the other. Due to the angle of inclination βi with βi>0° required for the ribs of the two cushion parts, the ribs of the cushion parts arranged one above the other, which are straight for example here, intersect at crossing points. According to the invention, the first recesses are on the upper edges of the ribs 110 of the first cushion part 100 at the location of the crossing points formed and are there in engagement with the ribs, in particular with the upper edges 112 of the ribs of the second cushion part. This interlocking does not necessarily require the presence of first recesses 114 also on the upper edges of the ribs of the second cushion part. However, first recesses can also be formed on the upper edges of the ribs of the second cushion part in the crossing points; then the first recesses of the two upholstery parts engage in each other at the crossing points. The interlocking or the interlocking of the two cushion parts advantageously in any case ensures stability of the packaging arrangements formed in this way against shearing forces acting from outside.

The first recesses 114 both on the upper edges of the ribs of the first upholstery part and, if applicable, the first recesses on the upper edges 112 of the ribs 110" of the second upholstery part are designed to be inclined with respect to the longitudinal alignments L of their respective upper edges 112 for the purpose of optimal meshing . Only this oblique design of the second recesses 114 ensures that the two upholstery parts mesh optimally, because the ribs and in particular the upper edges of the ribs of the two upholstery parts also meet at an angle at the crossing points. The oblique design of the first recesses 114, 114" compared to the Longitudinal alignments of the upper edges of the ribs of the first and/or the second padding part corresponds to the crossing angle at which the facing ribs of the first and the second padding part intersect when arranged one on top of the other.

If, as in the 3 and 4 shown, the objects 20 are not received completely, ie in particular not in their full height, by the second recesses 116 on the first cushion part 100, then they project upwards beyond this first cushion part. In these cases, it is necessary for the second recesses 116 on the upper edges of the ribs of the second padding part 100" to be shaped in such a way that, in the case of the described intervention in the first padding part below, they contain the upwardly protruding part of the object 20 to be packaged to record.

At the in the 3 and 4 In the packaging arrangements shown, the cushion parts arranged one above the other are then hooked together due to the first recesses 114 and at the same time the object 20 to be packaged is securely mounted or protected, in particular against lateral shearing forces between the two cushion parts.

If the second recesses 116 in the first padding part 100 are already large enough to fully accommodate the item to be packaged, even vertically to the common base area 20, so that the item 20 does not protrude beyond the first padding part, then opposite ones are second recesses in the ribs of the placed second cushion part 100 "dispensable. On the other hand, if this requirement is not met, as in the 3 and 4 shown, then it is necessary that the second recesses 116 in the upper edges of the ribs 110'' of the first and second padding parts 100, 100'' face each other in order to completely accommodate the object 20 to be packaged between the two padding parts.

• In 3 sind zwei Polsterteile gemäß der ersten Ausführungsform, d. h. ohne Ausbildung von Rippen an der Unterseite der Grenzflächen 120, 120'' übereinander angeordnet. Demgegenüber sind in 4 jeweils zwei Polsterteile gemäß dem zweiten Ausführungsbeispiel, d. h. mit jeweils der Ausbildung von Rippen an den Ober- und Unterseiten der Grundflächen 120, 120'' übereinander angeordnet. Grundsätzlich sind auch Mischformen denkbar, wobei ein Polsterteil gemäß der zweiten Ausführungsform und ein Polsterteil gemäß der ersten Ausführungsform übereinander angeordnet sind.

4 differs from 3 in the following points:

• In 3 are two padding parts according to the first embodiment, ie without the formation of ribs on the underside of the boundary surfaces 120, 120 '' arranged one above the other. In contrast, in 4 two upholstery parts according to the second exemplary embodiment, ie arranged one above the other with the formation of ribs on the upper and lower sides of the base surfaces 120, 120''. In principle, mixed forms are also conceivable, with an upholstery part according to the second embodiment and an upholstery part according to the first embodiment being arranged one above the other.

Another difference between the 3 and 4 is that in 4 the first and second padding parts 100, 100'' which are arranged one above the other and are in engagement with one another are placed in a container 30 with the object 20 to be packaged between the two padding parts. In this case, it is preferably the case that the external dimensions of the two cushion parts which are arranged one above the other and are in engagement with one another correspond at least at certain points to the internal dimensions of the container 30 . This then ensures that the padding parts are not freely movable within the container. It can also be advantageous if at least sections of the covers or the edges of the base areas 120, 120'' of the two cushion parts 100, 100'' are superimposed congruently. This feature can relate both to the packaging arrangement without container 30 and with container 30 .

• 5 zeigt ein drittes Ausführungsbeispiel für das erfindungsgemäße Polsterteil. Charakteristisch für das dritte Ausführungsbeispiel ist, dass die Rippen 110-1, 110-2 hier beispielhaft gekrümmt ausgebildet sind. Der Aufnahmeraum 130 für den zu verpackenden Gegenstand 20 ist zum einen durch den Zwischenraum zwischen benachbarten Rippen, aber auch durch den ausgesparten Raum der zweiten Ausnehmungen 116 in den Rippen gebildet. An den gekrümmten Rippen sind jeweils zwei erste Aussparungen 114 zu erkennen, wobei die beiden Aussparungen an jeweils einer Rippe jeweils unterschiedlich ausgerichtet sind.

Also, the left figure in 4 10 shows how the recess 114'' of the second upper cushion part 100'' embraces the upper edge 112 of the first lower cushion part 100 when the two cushion parts are arranged one on top of the other and are interlocked with one another.

• 5 shows a third embodiment of the upholstery part according to the invention. It is characteristic of the third exemplary embodiment that the ribs 110-1, 110-2 are curved here, for example. The receiving space 130 for the object 20 to be packaged is formed on the one hand by the intermediate space between adjacent ribs, but also by the recessed space of the second recesses 116 in the ribs. Two first recesses 114 can be seen on each of the curved ribs, with the two recesses being oriented differently on each rib.

6 shows an example of the packaging arrangement 150 according to the invention, constructed from the cushion parts arranged one on top of the other according to the third exemplary embodiment according to FIG 4 . The interlocking between the first upholstery part 100 and the second upholstery part 100" arranged folded over it can be clearly seen. The interlocking is realized by the first recesses 114, which are formed here by way of example both on the first upholstery part and on the second upholstery part and here according to the invention Due to the interlocking, the two cushion parts can no longer shift relative to one another when shearing forces act, and the object 20 to be packaged between the two cushion parts is in this way effectively spared from external forces.

In addition, 6 It is easy to see that the base areas 120, 120" of the two cushion parts 100, 100" are congruently one on top of the other. This promotes the stability of the cushion parts arranged one on top of the other when they are placed in a container which, with regard to its internal dimensions, preferably corresponds to the external dimensions of the base areas 120, 120''.

6 also reveals the reason why the two first recesses 114 at the top edges of the ribs of the first cushion part are oriented in different directions. The reason is that the tangents on the ribs of the second padding part are different at the two crossing points.

The 7 and 8th show the upholstery part according to a fourth embodiment with straight ribs 110, 110''. Otherwise, the statements according to the 5 and 6 analogous.

In addition, in 7 Steps 118 can be seen in individual walls of the ribs 110, which protrude into the spaces between opposing adjacent ribs. These steps serve to support objects to be packaged, which are arranged between two ribs in each case, provided these objects are not supported by the second recesses 116 in the z-direction.

Finally shows 9 a fifth exemplary embodiment of the upholstery part according to the invention, in which the ribs 110-1, 110-2 are each formed locally curved. The local curvature preferably corresponds to the outer contour of the object 20 to be packaged in a locally limited area. The object 20 to be packaged is preferably mounted with a precise fit or without play between the two ribs. The object 20 is preferably also supported in the z-direction, ie perpendicular to the plane of the drawing, by a said step 118 .
