Description

The invention relates to a transport packaging made of cardboard-like material for bulky, flat and / or curved objects according to the preamble of claim 1.

A transport packaging of the type mentioned is through DE 202 09 462 U1 known. This packaging is a container made from a blank, the side walls of which have been created by unfolding longitudinal grooves on the blank. As a material for the transport packaging corrugated board is provided, which is indeed suitable for packaging furniture panels, but not of fragile panels or glazed frames. The work or furniture panels packed with the corrugated board themselves ensure the desired rigidity of a unit consisting of the packaging and its contents. The packaging as such is unstable and requires extremely careful handling.

So will in the DE 200 07 124 U1 a packaging element of corrugated cardboard for packaging at least partially flat-shaped objects disclosed in an outer packaging, wherein the packaging element consists of a cushion and a plurality of such packaging elements serve for fixing the article in or at its edge areas within the outer packaging. The conventional pad is at least two parts and these upholstery parts are supported by a bending and / or foldable connecting web and arranged in the region of the free ends of the legs of the web, so that the inclusion of the flat-shaped object between the upholstery parts under firm restraint against the Area of the object is guaranteed.

However, there is the disadvantage that the conventional packaging element is not sufficiently stable to store fragile flat goods, such as window panes and glass panes of motor vehicles, let alone transport them free from glass breakage, so that the conventional packaging element is not suitable for transport, e.g. using forklifts, when used in high shelves.

This in CH 420 980 A Although described packaging auxiliary element has to form a plate or strip-like, serving as a cushion filler a falzbare web with double-sided self-adhesive strips. The upper self-adhesive strips are offset from each other to the lower self-adhesive strips, so that when they lie in the stretched state they do not touch each other, but when folding the self-adhesive strips of each web page come to rest on each other, stick together and transform the web parts into a solid packing.

The conventional packaging auxiliary element can not be adapted to any shape and size of the objects to be protected and transported, such as electronic devices, glass kitchen components, fragile flat goods, such as glass, so that the objects to be transported are not permanently protected from shocks positionally unverrutschbar and not can be preserved against edge breakage and edge breakage of the object.

The object of the invention is to design a generic transport packaging, which is more stable and is suitable for the transport and storage of fragile flat goods, which also forklift can be used.

The object of the invention should also be to provide a transport packaging, which is not only adapted to the shape and size of the objects to be protected, but possibly as far as possible the objects remain permanently secure against impact in the interior of the shipping packaging to be provided without edge breakage and edge breakage.

Coming to the interior of the transport packaging to be provided should be protected against the ingress of water or moisture.

In addition, the transport packaging to be provided should be low in volume and weight, so that the transport costs, which are essentially based on the size, loading meter and / or weight of the transport packaging of the articles, are low.

Also, the transport packaging to be provided should be recyclable and make it possible to open it at any time for the purpose of checking or monitoring customs, hygiene regulations or other regulations.

The problem is solved by the main claim and the secondary claim. The subclaims relate to preferred embodiments and embodiments of the invention.

The invention relates to a transport packaging of cardboard-like material for bulky, flat or curved objects, such as flat, curved or curved glass panes, glazed doors or windows, or the like, according to claim 1.

• wenigstens die zwei sich gegenüber liegende Seitenwände des Behälters jeweils aus wenigstens einer Flachleiste aufgebaut sind, die auf das Bodenteil längs seiner Seitenkanten angebracht und mit dem Bodenteil verbunden ist,
• der Behälter sich an wenigstens zwei Stützeelementen palettenartig abstützt,
• und das kartonartige Material, aus dem wenigstens das Bodenteil, Seitenwände und die Stützelemente gefertigt sind, Wabenpappe ist.

The object is also achieved by a transport packaging of the type mentioned, in the

• at least the two opposite side walls of the container are each made up of at least one flat strip, which is mounted on the bottom part along its side edges and connected to the bottom part,
• the container is supported like a pallet on at least two support elements,
• and the cardboard-like material from which at least the bottom part, side walls and the support members are made is honeycomb cardboard.

A trough-shaped design of the container made of honeycomb cardboard ensures high stability and rigidity of the transport packaging according to the invention.

For the purposes of the invention, honeycomb cardboard is also understood to mean a material which preferably consists of kraft paper and is shaped around uniform hexagonal cells which can form a core layer, which in turn can be reinforced on both sides with one or more cover layers. Honeycomb board may be a material of special stiffness consisting of paper stock, the basis weight of which may be above 225 g / m ² , for example. The material may also be a cardboard-like, for example, be with a basis weight of 150 - 600g / m ² . The use of pallet-like support elements facilitates considerably the manual and mechanical handling with the transport packaging. The cover layers can be glued together or -gegautscht together. The transport packaging according to the invention is stackable, shock absorbing, heat insulating, reusable and completely recyclable as needed. The shock-absorbing properties can be further improved by the use of cushioning elements.

The upholstery element can be an upright edged on the bottom part, also made of honeycomb cardboard flat bar. The insert is advantageously connected to the lid.

The support elements are preferably arranged parallel to each other; Also, the support members may each extend over a width dimension (B) of the bottom part. In a further embodiment, the support elements in each case in at least one over the side edge of the bottom part cross and the side wall to its free edge tightly surrounding L-leg over. In addition, the support elements in their transition areas to L-legs can form a common axis of rotation (A), so that the transport packaging from its horizontal position in a stable vertical position and vice versa is pivotable.

Preferably, the support elements each extend over the entire width or length of the bottom part and merge into a cross over the side edge of the bottom part L-leg. In this case, the L-leg can reach up to a free edge of the side wall of the container. Characterized in that the support elements are L-shaped, their transition areas to L-legs can form a common axis of rotation about which the transport packaging from its normally horizontal position in a stable vertical position and vice versa can be pivoted. In the vertical position, the entire weight of the transport packaging is carried by the L-legs of the support elements. In addition, it is provided to reinforce the support elements and their L-legs by each consisting of two or more glued strips of honeycomb cardboard. Not without significance also a clear, free cavity between the support elements, in which the tines of a forklift can be inserted. Preferably, at least two opposing side walls of the container of superimposed and glued together flat strips, here: strip of honeycomb cardboard formed. The flat strips made of honeycomb cardboard can also be placed edgewise on the bottom part.

The flat strips of the side wall can be laid flat on the bottom part. It is also possible that the flat strips of the side wall are placed edgewise on the bottom part. Between the side walls, at least one additional, strip-shaped, shock-absorbing upholstery element can be arranged, which divides the interior space into at least two compartments or more than two compartments of similar or dissimilar design. In addition, the lid may have depending side parts which cover the side walls in the closed position of the transport packaging. Likewise, the lid can be made in one piece from a cardboard-like blank whose side part may have interruptions, in which the L-legs of the support elements can fit. At least one cardboard or paperboard section may be attached to the side wall of the container. At least on the bottom part edge protection elements may be provided.

Although the container made of honeycomb cardboard is inherently shock-absorbing and torsionally rigid, the fragile object accommodated in the container should be packed tightly and non-sliply. For this purpose, strip and plate-shaped padding elements are provided, which may also be made of honeycomb cardboard or other shock absorbing materials. It can also be shorter spacers are used, which are also made of honeycomb cardboard. Furthermore, adhesive dots or strips can be provided, which come into contact with the edge or frame or border of the respective article to be protected.

The lid can be one or more parts. Preferably, the lid is made in one piece from a blank, which consists of a cardboard or paperboard layer and the side part has interruptions, in which the L-legs of the support elements fit. However, the cardboard-like blank can be glued to a honeycomb cardboard insert or connected in any other way, leaving free depending side parts of the lid.

Any requirements for watertightness of the transport packaging can be fulfilled by laminating a film layer to the cover layer of the honeycomb board. In the interior of the container, several flat objects of the same extent can be inserted. However, this requires the use of appropriate liners. Of course, it is possible to place objects of different dimensions in a container.

In the transport packaging according to the invention, the adhesive is in the form of adhesive dots or adhesive strips, which come into contact with the edge and / or frame of the respective object to be protected. The adhesive may be applied in those areas of the interior of the transport packaging according to the invention, which may come into contact with the object to be protected. Thus, the adhesive may be applied to at least one of the insides facing the interior e.g. the bottom part, the insert, the side walls and / or the lid may be applied.

Applying in the sense of the invention is also understood to mean that the adhesive is connected to or applied to the surface of one side, eg, the inner sides facing the inner space, as glued, sprayed, brushed, scrapered and / or -laminated.

In the context of the invention, adhesive strips are also understood as adhesive dots, adhesive strip profiles.

Adhesive is also understood in the context of the invention, adhesive tape, adhesive tape, adhesive emulsion, adhesive, adhesive foam, rubber coating, latex coating, an adhesive layer with pressure-sensitive adhesive or hot melt adhesive, etc.

For example, the adhesive may be a pressure-sensitive adhesive. A pressure-sensitive adhesive may be a viscoelastic adhesive which remains permanently tacky and tacky in solvent-free form at 20 ° C. and immediately adheres to the object to be protected if there is little or no substrate specificity with slight contact pressure.

The adhesive bonds produced, for example, with the pressure-sensitive adhesive, such as adhesive tapes, can be detached from the inner sides of the transport packaging according to the invention and / or from the article without destroying the object adhering to the pressure-sensitive adhesives. Basic polymers of the conventional pressure-sensitive adhesive may be natural rubbers, synthetic rubbers, polyacrylates, polyesters, polychloroprenes, polyisobutenes, polyvinyl ethers, polyurethanes and / or mixtures thereof, e.g. in combination with additives such as resins, plasticisers and / or antioxidants.

The adhesive strips may be configured as adhesive tapes or adhesive films on the side or sides of the transport packaging according to the invention, which come into contact with and adhere to the object to be protected.

The adhesive tapes may be referred to as so-called single-band adhesive tapes or of the single-band type, for example of a support or a carrier layer made of paper, a plastic film, a textile fabric or the like and a pressure-sensitive adhesive, for example natural rubber with, for example, modified rosin or other resins consist. The adhesive is at least preferably on the side, also called underside, of the carrier or the carrier layer, which can be connected to the inside of the transport packaging according to the invention and / or with the object to be protected.

If, for example, the inner sides of the transport packaging according to the invention delimiting the interior are at least partially, such as partially flat, or provided with adhesive over the entire surface, the object is coupled to the adhesive strip by the slight application of force to the adhesive tape with the aid of the object to be protected, such that it also slips when exposed violent shocks on the transport packaging according to the invention, is avoided. The object can adhere with the side facing away from the bottom of the adhesive strip, also called top side, by contact pressure adhesive so that no slippage of the article in the interior of the transport packaging according to the invention in the closed position during transport and impact of shocks is able to adjust.

Adhesion also means within the meaning of the invention the ability, also called adhesion, e.g. the top of the tape to be releasably anchored to the article with the result of good or sufficient adhesive strength. The adhesion of the article and / or the inner sides of the transport packaging according to the invention can be provided by at least one adhesive layer. The adhesive layer may be a pressure-sensitive adhesive or other adhesive to make the solubility of at least the article of the inner sides of the transport packaging according to the invention possible.

For the purposes of the invention, adhesive strength is understood as meaning the entirety of the binding forces between the adhesive and the object, surface, edge, edge thereof, or a part thereof.

The use of pressure-sensitive adhesives on at least one side or both sides of the adhesive tapes e.g. of the single-band type for releasable anchoring in the transport packaging according to the invention with conventional viscoelastic adhesives also allows the

Multiple use of the same, because the object of the adhesive strips provided with the pressure-sensitive adhesive is readily solvable, without that neither the object nor the adhesive strip can be damaged. The adhesion between the object to be protected and the adhesive strip is sufficient to make the transport, in particular impact-sensitive objects, such as curved glass, mirrors, solar cells, plastic discs or the like, shatterproof.

The adhesive strength between the adhesive strip and the object to be protected may also be made possible by the permanently adhesive adhesives as pressure-sensitive adhesives, particular preference being given to those pressure-sensitive adhesives which adhere as permanent-adhesive adhesives, preferably based on rubber, under low contact pressure on the inner sides of the transport packaging according to the invention and under continuous load may tend to flow to increase the adhesive surface between the article and the transport packaging according to the invention advantageously.

The adhesive emulsion as an adhesive, for example, on the inner sides of the interior of the transport packaging according to the invention, which come into contact with the object, applied, brushed, sprayed or the like to the adhesion of the object to be protected with the transport packaging according to the invention the security against breakage or other mechanical Increase damage. Also, for example, adhesive foams can be sprayed on, brushed on, or otherwise applied in order to achieve an adhesive effect between the article and the transport packaging according to the invention.

When using the adhesive in the form of, for example, adhesive foams, the adhesion between the article and the transport packaging according to the invention is still noticeably enhanced by the air bubbles trapped in the adhesive foam, which can protect against bumps in the case of the filled transport packaging according to the invention as an airbag.

Also, at least partially, the inner sides of the interior of the transport packaging according to the invention can be gummed over part of the surface or over the entire surface.

For the purposes of the invention, gumming is also understood as meaning the coating with sticky substances, such as rubbers, in order to prevent slippage of the article to be protected.

The adhesive tapes can be designed as so-called two-volume adhesive tapes or of the double-banded type.

The double-sided adhesive tape comprises, for example, the first tape a carrier layer and a pressure-sensitive layer applied on one side of the carrier layer with an adhesive which is a pressure-sensitive adhesive or a hot-melt adhesive, for co-acting with one or more inner sides of the transport packaging according to the invention by means of adhesion and one on top of the other Side of the carrier layer arranged layer or a coating with barbs. The second band comprises, for example, a carrier layer and a fluffy layer arranged on one side of the carrier layer for co-operating with the barbs of the first band and a pressure-sensitive adhesive layer applied on the other side of the carrier layer of the second band, which adheres to the article to be protected interacts.

The first strip may also have a carrier layer and a pressure sensitive layer applied on one side of the carrier layer with an adhesive, which is a pressure sensitive adhesive or a hot melt adhesive, for cooperation with inner sides of the transport packaging according to the invention by means of adhesion and a on the other side of the carrier layer arranged layer or a coating with mushroom-shaped barbs. The second band may comprise a backing layer and a mushroom barb-type coating on one side of the backing layer for cooperation with the mushroom barbs of the first band and a pressure-sensitive adhesive layer applied to the other side of the second band backing layer Object cooperates by adhesion.

Thus, the first band with its applied on one side of the carrier layer pressure-sensitive, pressure-sensitive adhesive layer with the inner sides of at least a portion thereof the transport packaging according to the invention, possibly solvable, and can applied the second band with its on the other side of the carrier layer of the second band pressure-sensitive adhesive layer are releasably connected or glued to the object to be protected. When touching the two bands, the barbs of the first band hooked with the fluffy layer of the second band, so that also allows a sufficient positional security and slip resistance of the object to be protected in the transport packaging according to the invention are supported.

By providing the inner sides or those areas of the inner sides of the transport packaging according to the invention, which are facing the object inserted into the interior of the transport packaging and come into contact over part of the surface or the entire surface, with adhesive tape, the position security of the article already provided by the transport packaging according to the invention is effective Interior of the transport packaging according to the invention increases.

In contrast to the prior art, the adhesives contribute to the fact that adhesives can be applied cost-savingly only on a few areas of the insides of the transport packaging according to the invention, in order to develop the releasable adhesive strength of the object to be protected with the transport packaging according to the invention.

In addition, because of the application of the adhesive, a plurality of flat objects, such as glass panes, can be transported in series with the transport packaging according to the invention. The transport packaging according to the invention also makes it possible to transport glass panes stacked one on top of the other, closely stacked but spaced from one another, wherein at least the edges of the glass panes or their frames can be adhered to the insides of the interior of the transport packaging according to the invention with the aid of the adhesives.

It turns out that particularly violent shocks acting on the transport packaging according to the invention, for example in the transport of small items such as glass panes, electronic appliances, glass kitchen components, have no effect on these objects to be protected, since the application of the adhesives prevents undesired slippage of the articles in the article Help to avoid interior of the transport packaging according to the invention.

It is also possible that the adhesive strips can be configured as adhesive strip profiles. The adhesive strip profiles may, for example, be cylindrical in cross section, such as a hollow body. The hollow-body-shaped adhesive strips may have a layer on the outside with the pressure-sensitive adhesive. Due to the adhesion of the object to be protected with the layer of pressure-sensitive adhesive of the hollow body-shaped adhesive strip profile not only the object to be protected with the transport packaging is intimately connected, but also serving the located in the adhesive strip profile Cavity as a buffer in the presence of particularly violent shocks as a so-called airbag, which are able to act on the glass panes from the outside.

Also, the adhesive strip profiles can have the same extending cavities in longitudinal section or plan view. Likewise, interrupted cavities are suitable by internal walls drawn into the cavities as a shock buffer. Likewise, it is possible that the adhesive strip profiles have cavities whose cavities are delimited by honeycomb-shaped inner sides in cross section. Also, the adhesive strip profiles on the side opposite the layer of pressure sensitive adhesive may be provided with a fluffy layer which cooperates with the first band of adhesive tapes of the two-band type and their barbs by engaging barbs in the fluffy layer.

The pressure-sensitive adhesive layer can also contain a water-activatable adhesive, such as dextrin or glutin glues.

As adhesives also hot melt adhesives can be used. Hot melt adhesives are preferably solid at room temperature, water and solvent free adhesives, e.g. be applied to the adherends inside the transport packaging of the invention from the melt and physically set during cooling and solidification.

As hot melt adhesives hot or hot adhesives but also heat sealing adhesives can be used, for example, part of the wall, applied to the inner sides of the transport packaging according to the invention as a film, dot, bead, sprayed on, brushed, for example, according to the size, shape, number of in the interior to be placed and protected items.

As a raw material base of the hot melt adhesives find polymers use, such as E / EA, E / VA, PA, PES, PIB, PVB or mixtures thereof. In many cases, these polymers can be used and applied together with natural or synthetic resins and / or paraffins or microwaxes.
