Description

The present invention relates to packaging, and more particularly to insulating packaging. Such insulating packaging is used, for example, to transport products to be temperature-controlled, in particular products to be cooled. These products can be perishable food, for example, but also medicines. Such packaging is required to allow the respective product to be kept cool safely at least over a certain period of time.

For this purpose, it is known from the prior art to introduce an additional insulating material, for example Styrofoam snippets or the like, into the packaging in order to improve the thermal insulation. Nevertheless, there is a need in the market to dispense with such filler material.

According to the invention, these objects are achieved by the subject matter of the independent claims. Advantageous embodiments and developments are the subject of the dependent claims.

An insulating packaging according to the invention, in particular for packaging portable objects, has a base part which has at least two, preferably at least three and particularly preferably at least four side walls that are connected to one another via first folds and a first base section that can be closed by folding, this bottom section being arranged on a first side wall via a second fold.

According to the invention, at least one section of the insulating packaging has a coating with at least one layer, this layer being a coating printed on this section and the coating being a substance containing a metal, in particular a paste containing a metal and in particular a substance containing silver (in particular silver particles) and / or paste.

It is therefore proposed according to the invention that at least one section of the transport packaging and / or insulating packaging has a coating which serves in particular for insulation and in particular for thermal insulation.

It is pointed out that the packaging device described here can be used both for packaging and / or transporting products to be cooled and for packaging and / or transporting products to be kept warm.

The present invention therefore also relates in particular to the use of the insulating packaging described here for packaging products that are to be kept cool, in particular foodstuffs and / or medicines.

The packaging is preferably made from a paper and / or cardboard material. In particular, the mentioned coating is applied to a section which consists of paper and / or cardboard. Corrugated cardboard in particular can also be used here.

The bottom part of the insulating packaging is understood to mean in particular that part of the packaging which forms the receiving volume or at least a considerable part of the receiving volume for receiving the portable objects.

This coating is preferably applied to several sections of the insulating packaging and particularly preferably to all sections.

The metal coating can be used to ensure that the respective section reflects thermal radiation and thus contributes to the insulation of the packaging.

In a preferred embodiment, the layer contains at least 5%, preferably at least 10%, preferably at least 15% silver paste and / or the coating contains at most 40%, preferably at most 30% and particularly preferably at most 25% a silver paste and / or metal paste.

This paste preferably has binders as further components. This silver paste can also be a so-called aluminum cut. In addition, it would also be possible for the coating to be mixed with other materials, for example with gold or other metals.

In this case too, however, the color is preferably composed of the above-mentioned proportions of silver paste (aluminum polish).

In a further preferred embodiment, the coating can have an antibacterial effect. For example, the layer can contain silver ions.

In a further preferred embodiment, the layer is arranged on the section as at least one layer, preferably as at least two layers arranged one above the other and particularly preferably as at least three layers arranged one above the other. In other words, the coating is preferably applied at least once, preferably at least twice and particularly preferably at least three times in the production process. This can be achieved, for example, in that one, two or more inking units with the same color are connected in series. In this case it would be possible to achieve a total coating with about 60% silver paste, the individual layers each having, for example, 20% silver paste.

In a further preferred embodiment, the coating is a layer applied using a flexographic printing process.

The coating is preferably a radiation-reflecting coating. In particular, the coating is suitable and intended to reflect radiation in the infrared wavelength range. In particular, the coating for radiation in the infrared wavelength range has a degree of reflection of at least 30%, preferably of at least 40%, preferably at least 50%, preferably at least 60% and particularly preferably at least 70%.

In a further preferred embodiment, the coating and / or the layers are food-safe. This means in particular that the coatings meet the standards of DIN EN 646 with regard to food safety.

In a further preferred embodiment, a further protective layer is arranged on the coating. This protective layer can in particular, but not exclusively, be a protective lacquer that prevents the coating from being rubbed off. In this case, it would be possible, for example, for four printing units to be used one behind the other, the first three printing units applying three layers and the fourth printing device applying the protective lacquer.

Again, this protective lacquer is particularly preferably food-safe and in particular food-safe according to DIN EN 646.

In a further advantageous embodiment, the at least one section of the insulating packaging has a first surface and a second surface opposite this first surface, and the coating is applied to both surfaces. Said section is therefore particularly preferred and a plurality of sections and particularly preferably all sections are particularly preferably coated on both sides. In this way an even better insulation is achieved.

The respective section or the material is particularly preferably corrugated cardboard, the aforementioned coating preferably being applied to both sides of this corrugated cardboard. This coating also creates a higher diffusion density.

In a further advantageous embodiment, the insulating packing has a cover part which can be separated from the base part, and this cover part also preferably has at least one coated section. Particularly preferably, the lid part has at least one adhesive on the surface facing the interior of the packaging, for example around a cooling pack and / or a further packaging unit to be attached, wherein this further packaging unit can in particular contain such a cooling pack.

In a further advantageous embodiment, the insulating packaging has at least one inner packaging that can be received by an interior of the bottom part. This inner packaging can serve to introduce a coolant, for example a cooling gel (or the above-mentioned cooling pack) into the packaging.

The insulating packaging particularly preferably has at least two inner packaging that can be received by the interior of the bottom part. It is possible that such an inner packaging is placed on the bottom of the packaging device and the other is attached to the lid, as mentioned above. In this way, the goods to be cooled can be arranged between these two cooling elements.

This insulating packaging is particularly preferably also coated in the interior of the packaging at least in sections and preferably completely.

In a preferred embodiment, the inner packaging can in turn be suitable for receiving a cooling bag or a coolant. Particularly preferably, the inner packaging likewise has a multiplicity of side walls, with openings being particularly preferably provided in at least one of these side walls. These openings are used in particular for heat exchange.

In a further advantageous embodiment, the floor section has a floor base part and a reinforcing part that can be inserted into this floor base part. This reinforcement part can be designed as a plate-like element.

However, it is also possible for the floor to also have a two-layer or two-layer structure.

In a further advantageous embodiment, at least one side wall is at least double-walled. It is particularly preferable for at least one side wall to have at least three layers or three walls.

In a further advantageous embodiment, it is also possible for a side wall to have four layers.

In a further advantageous embodiment, the insulating packaging has an insulating ring which surrounds the interior of the packaging. This insulating ring can preferably be inserted separately into the packaging when it is assembled.

The insulating ring is also particularly preferably made from cardboard. This insulating ring can have an angular cross section and in particular also a rectangular cross section and in particular also a cross section which essentially corresponds to the cross section of the packaging itself. This insulating ring is particularly preferably made from an elongated cardboard element. This insulating ring is particularly preferably also insulated at least on one side and particularly preferably on both sides. In an assembled state, the walls of this insulating ring preferably run essentially parallel to the above-mentioned side walls.

This insulating ring is preferably in contact with the individual side walls of the insulating packaging. Furthermore, it is also possible that said insulating ring is inserted between the walls of the side walls.

A fastening section is advantageously arranged on the first base section which, in an unfolded state, can be fastened to that side wall which is opposite the first side wall in the unfolded state, the transport packaging having a fastening means which is used to fasten the fastening section to this (opposite) Sidewall is suitable and intended. A fastening section is understood to mean, in particular, a section which is intended to be fastened to another section or area.

Another advantageous foldable transport packaging and / or insulating packaging, in particular for packaging portable objects, has at least four side walls that are connected to one another via a first folding point and a first floor section which can be moved and in particular closed by folding, this first floor section having a second folding point a first side wall is arranged and / or can be arranged.

It should be noted that the transport packaging described in the present description can also be insulating packaging. In particular, however, the insulating packaging is also transport packaging.

A first holding section is advantageously arranged on the first base section, which in an unfolded state rests against a side wall which is arranged on the side wall.

A further side wall arranged on a side wall is understood in particular to mean that this further side wall directly adjoins the first side wall and in particular is connected to this first side wall by means of one of the above-mentioned folds.

This holding section is preferably designed in such a way that it supports the base section while the carton is being lifted. It is thus possible that the holding section can be gripped by the user carrying the transport packaging.

This holding section is preferably arranged within the side walls in the assembled state of the transport packaging.

In a further preferred embodiment, a second holding section is arranged on the first base section, which in an unfolded and / or assembled state rests against a side wall which is arranged on the side wall. This is preferably a further side wall which rests against the above-mentioned first side wall.

The two holding sections are preferably arranged on opposite edges or sides of the bottom section. The above-mentioned bottom section is preferably arranged between the holding sections.

In a further advantageous embodiment, the bottom section is connected to at least one holding section and preferably to both holding sections via a fold. In a further advantageous embodiment, at least one holding section has an opening which, in an unfolded and / or assembled state of the transport packaging, is arranged at least partially in alignment with an opening arranged in the side wall.

In this way, it is possible for a user carrying the transport packaging to be able to grip both through the opening arranged in the side wall and through the opening arranged in the holding section. Since the bottom section is arranged on the two holding sections, the user directly carries the bottom of the transport packaging in this way.

A bottom section is preferably also arranged on the remaining (fourth) side wall, which, in an assembled state of the transport packaging, rests against the above-mentioned bottom section. The above-mentioned bottom section is preferably arranged closer to the interior of the transport packaging than the bottom section arranged on the remaining side wall.

The present invention is further directed to a foldable transport packaging, in particular for packaging portable objects, the transport packaging having side walls that are connected to one another via at least four first folding points and preferably a first bottom section that can be closed by folding. In this case, the first base section is preferably arranged on a first side wall via a second fold, and the transport packaging has a cover unit.

According to the invention, the cover unit has a cover base and at least one first cover fastening section arranged on the first edge of this cover base and a second cover fastening section arranged on a second edge of this cover base, this first cover fastening section and the second cover fastening section being attachable to the side walls.

It should be noted that this multi-part transport packaging can be used with or without the above-mentioned coating.

At least one adhesive and preferably a plurality of adhesives can preferably be arranged on the cover unit in order to arrange and in particular to glue a further device, for example an inner packaging, to the cover unit.

A transport device with a cover unit which is still separate at least in a folded state is therefore proposed. The transport packaging is thus designed in two parts in the delivery state. As explained in more detail below, the cover unit can preferably be glued to the remaining area of the transport packaging and in particular the base part of the packaging device.

In a further advantageous embodiment, the transport packaging has exactly four base sections, which are particularly preferably each connected to a side wall. Advantageously, all of the bottom sections are each connected to the respective side walls via folds.

In a further advantageous embodiment, the transport packaging has exactly four side walls. In this embodiment, the transport packaging has a square or rectangular cross section. Advantageously, at least two and preferably mutually opposite bottom sections are fastened to one another with the fastening element.

In a further advantageous embodiment, the adhesive or fastening means has an adhesive coating. This adhesive coating thus serves to attach these two sections to one another.

It is advantageously a single-use fastening means. This means that a connection established by this fastening means can no longer be released without destroying at least a section of the packaging. Although it is accepted that the packaging can only be folded once, the fastening means can achieve a very high stability of the base.

In a further advantageous embodiment, the first floor section and the second floor section lie opposite one another. In other words, that is preferred Side wall on which the first base section is arranged, opposite that side wall on which the second base section is arranged.

In a further advantageous embodiment, the first base section has a surface facing the interior of the transport packaging and a surface facing away from the interior of the transport packaging in an assembled or built-up state of the transport packaging.

The fastening means preferably has an adhesive coating.

The first side wall preferably extends in a longitudinal direction of the transport packaging and in a height direction of the transport packaging. The second side wall opposite the first side wall preferably also extends in this longitudinal direction and in the height direction.

One of the two further side walls preferably extends in a width direction and in the height direction of the transport packaging. The same preferably also applies to the fourth side wall.

The fastening section is preferably fastened to the base section via a fold. The drop point is an element which enables the fastening section to pivot relative to the bottom section. Such a fold can arise, for example, through a (section-wise) perforation of the material of the packaging device, so that a fold can be made more easily along lines in which such perforations are provided.
For example, when the packaging device is in an assembled state, it is possible to bend this fastening section at an angle of between 60 ° and 120 °, preferably between 70 ° and 110 °, preferably between 80 ° and 100 ° and preferably of about 90 ° with respect to the base section.

In a further preferred embodiment, this drop point extends parallel to the first side wall. This drop point preferably extends parallel to that drop point with which the first bottom section is arranged on the side wall. The base section preferably has an extension in the width direction of the packaging device which essentially corresponds to the inside width of the finished (or unfolded) packaging device. The first base section preferably also has an extension in the longitudinal direction of the packaging device which corresponds to the inner length of the completed or unfolded packaging device. In this case, however, these two extensions can also be slightly shorter, in particular in order to facilitate a movement of the base section or other sections relative to the side walls or their inner surfaces when unfolding.

In a further preferred embodiment, the adhesive or the fastening means is arranged either on a fastening section or on the corresponding opposite side wall (more precisely an inner surface of this side wall).

The fastening means or an adhesive layer is particularly preferably arranged on the fastening section. This has proven to be more beneficial when unfolding the appropriate packaging.

It is possible that this fastening section extends at least over half the length of the side wall or the packaging, preferably at least 60% of the length, preferably at least over 70% of the length.

In a further preferred embodiment, the fastening section has an area which is less than half the area of the first floor section on which the fastening section is arranged. The fastening section preferably has an area which is less than 40%, preferably less than 30% and preferably less than 20%, based on the area of the first base section on which the fastening section is arranged.

Furthermore, it is possible for the fastening section to extend along the entire wall, but it would also be possible for the fastening section to be designed like a tongue and, in particular, to taper outwards.

For example, this fastening section can have edges that run obliquely with respect to the width direction of the transport packaging.

In a further preferred embodiment, the adhesive or the adhesive layer is covered by a cover element in a folded state of the transport packaging. In the folded state of the transport packaging, the adhesive would lie against another surface and therefore stick to it. For this reason, it is proposed that a peelable cover film be arranged over the adhesive.

This adhesive can be removed during assembly and in particular immediately before the fastening section is fastened to the opposite side wall. It has proven to be advantageous if the adhesive is arranged on the fastening section, since this fastening section can then first be pressed down during assembly, the covering means can be removed and then the fastening section can be arranged on the side wall.

In a further preferred embodiment, a second base section is arranged from that side wall which lies opposite the first side wall in the unfolded or assembled state of the transport packaging. This bottom section can also be pivoted with respect to the relevant side wall and is connected in particular by means of this side wall via a folded section. It is pointed out again at this point that a folding section is characterized within the scope of the present invention in that the sections connected by this folding section can be pivoted with respect to one another just about the folding section. The fold section can thus also be referred to as a desired fold.

In a further advantageous embodiment, the second base section is arranged below the first base section when the transport packaging is in an unfolded state. Thus, particularly preferably in an unfolded state, an underside of the first base section, that is to say more precisely a surface which faces away from the interior of the transport packaging, is formed at least in sections adjacent to said second base section. In an unfolded state of the transport packaging, the two said bottom sections preferably lie against one another (in particular at least in sections).

In a further advantageous embodiment, the transport packaging is designed in one piece. This means that even in a one-piece state, the transport packaging can be fully unfolded and / or unfolded, that is to say in particular including a lid.

In a further preferred embodiment, a further base section is also arranged on at least one further side wall. In particular on such a side wall which connects the said first side wall and the second side wall (in particular via folds) and / or a side wall which, in the assembled state, represents one of the two transverse walls.

A further base section is preferably also arranged on the other further side wall. In an assembled state, it is possible for these two further floor sections to point farthest away from the interior space and for said second floor section to lie between the first floor section and the two further floor sections and, in particular, to lie flat against this at least in part.

In an unfolded state of the packaging device, these two further base sections are preferably spaced apart from one another and / or do not contact one another.

In a further preferred embodiment, this further floor section and the two further floor sections are preferably designed like a wing. These further floor sections preferably extend into the floor surface by less than half in the longitudinal direction of the first side wall. The bottom area is understood to mean that area which results geometrically from the area section enclosed by the side walls (in the unfolded state).

Furthermore, these further floor sections can also have sloping edges.

In a further preferred embodiment, these further base sections can also have folds or desired folds.

In a further preferred embodiment, at least one further floor section (ie a floor section arranged on at least one further side wall) is also attached to the first floor section. This further base section can particularly preferably be attached to the first base section by means of a further adhesive. This fastening can in particular, but not exclusively, also be present in a folded state of the transport packaging.

Particularly preferably, the remaining further floor section is also attached to the first floor section and / or the second floor section by means of an adhesive. This adhesive connection also advantageously already exists when the transport packaging is folded.

In a further preferred embodiment, the fastening means is arranged on the surface of the first base section facing away from the interior of the transport packaging. In an assembled state, as mentioned above, the fastening section is angled at a predetermined angle with respect to the bottom section, preferably at an angle between 60 ° and 120 °, preferably between 70 ° and 110 °, preferably between 80 ° and 100 ° and particularly preferred lies in a range of 90 °.

In a further advantageous embodiment, the first base section has a first surface section and a second surface section, which are connected to one another via a desired fold. The base section is thus preferably formed in one piece, but has a fold and in particular a desired fold.

This desired folding point can have a function in particular for unfolding the bottom section. Preferably, this desired folding point can run obliquely, that is to say in particular obliquely with respect to a width direction and / or with respect to the longitudinal direction of the base section and / or the transport packaging.

The present invention further relates to a kit for producing a transport packaging, in particular a transport packaging of the type described above. This has a first foldable section which serves to form the transport packaging, this foldable section at least four connected to one another via folds Having side walls, wherein the first foldable portion has at least one first floor portion connected to at least one side wall.

A fastening section is advantageously arranged on the first base section which, in an unfolded state, can be fastened to that side wall which is opposite the first side wall in the unfolded state.

At least one section of said kit preferably has a coating and in particular a coating of the type indicated above.

Furthermore, the transport packaging has at least one first fastening means, and in particular adhesive, which is suitable and intended for fastening the fastening section to this side wall.

Particularly preferably, this kit or the pattern has at least one second adhesive section and in particular one adhesive section with which a fastening section arranged on a further side wall can be adhered to said first fastening section.

The kit and / or the pattern preferably has a further adhesive section, in particular an adhesive section, by means of which at least two side walls can be attached to one another via a fold.

In an assembled state of the transport packaging, the fold via which the first base section is arranged on the side part assigned to it is preferably parallel to the fold via which the second base section is disposed on the side wall assigned to it.

In a further advantageous embodiment, the transport packaging is designed in one piece. The transport packaging is advantageously formed or folded from a one-piece folding material. The individual folds can already be formed in advance.

In a further advantageous embodiment, the transport packaging is made of paper or cardboard. The transport packaging advantageously has a cubic shape in a folded state.

In a further advantageous embodiment, the transport packaging also has a cover device. In this case, cover sections can be arranged on the side walls, which are folded together in a manner known from the prior art to close the transport packaging. At least two, preferably at least three and particularly preferably four such cover sections are advantageously provided. In this case, an adhesive strip can preferably also be provided on a surface of such a cover section in order to temporarily close the transport packaging. It would also be conceivable that one of the cover sections also has a tear-open section, so that the transport packaging can be opened quickly.

In a preferred embodiment, the first cover fastening section and / or the second cover fastening section can be fastened to an outer surface of the side walls. While in the case of transport packaging from the prior art, the lids may already be arranged on the base body in the form of lid sections, a separate but attachable lid is proposed here.

This procedure enables the stability of the cover to be increased compared to the prior art.

In a preferred embodiment (which relates in particular to the above-described embodiment with the separate cover unit) the first cover fastening section and / or the second cover fastening section can be fastened to an outer surface of the side walls. For this purpose, the at least one first or the second fastening section and preferably both fastening sections can also be foldable and / or pivotable with respect to the cover base area.

In a further preferred embodiment, at least one cover fastening section is fastened to the cover base surface via a fold. As mentioned above, this fold can again be a perforated area. This folding point or desired folding point allows the respective fastening section to pivot relative to the cover base surface. In this case, in an assembled state of the packaging device, the folding point can extend parallel to the first side wall. In particular, the fold can thus extend parallel to an edge of the relevant side wall.

In a further preferred embodiment, the fastening means or the adhesive is arranged either on the cover fastening section or on the side wall. It is possible here for the adhesive to extend essentially along the complete longitudinal direction of the side wall.

In a preferred embodiment, the device has an adhesive in order to fasten the fastening section to the side wall. This adhesive is preferably arranged on the fastening section. However, as an alternative or in addition, it would also be possible to arrange the adhesive on the respective side wall.

In a further preferred embodiment, the adhesive or the adhesive arranged on the fastening section and / or the side wall is covered by a cover element in a non-assembled state of the transport packaging. This can be a so-called liner, for example. This cover element prevents accidental gluing, for example during assembly. This covering element, which is designed in particular as a covering film, can essentially and preferably completely cover the actual (then underlying adhesive).

In a further preferred embodiment, a predetermined tear-open device or a predetermined separation point is arranged between the lid fastening element of the lid base area. By opening this separation point, the fastening element can be separated from the cover base, for example to open the cover. This procedure is suitable for one-way packaging that is to be opened once and can then no longer be closed or can no longer be closed without the viewer noticing this.

In this case, this intended tear-open device can have a section, in particular an edge section, which can be gripped by the user in order to separate the fastening element at this point. This edge section can be designed as a hand-grippable tongue, which is in particular separated from other areas of the fastening section by an incision.

In a further advantageous embodiment, a contact and / or fastening section is arranged on at least one further edge of the cover base area, which is connected to another Side wall can be applied and / or can be attached to this further side wall.

In a further preferred embodiment, an abutment is also arranged on the remaining fourth edge of the lid base area under the fastening section, which can be placed against a further side wall, namely the remaining fourth side wall, and / or can be fastened to this further side wall.

In this embodiment, the lid can therefore preferably be glued to the respective outer walls of the packaging at least three and preferably via four fastening sections or four adhesive sections. In this way, a particularly stable hold of the lid on the base body of the packaging device is ensured.

In a further advantageous embodiment, a reinforcement element is attached to the cover base. This reinforcing element is particularly preferably fastened to an inner side of the lid base surface, that is to say to a surface which faces inward in an assembled state of the packaging device.

This reinforcing element can preferably be a further flat element, in particular made of paper or cardboard, which is particularly preferably fastened and in particular glued to the inner surface of the cover base. This reinforcing element is particularly preferably glued flat. In this way, significantly increased stability is achieved in the area of the cover.

The reinforcing element is particularly preferably a cardboard panel. It is pointed out that the reinforcement element described here can also be used in connection with other cover devices, in particular cover devices that are designed without the fastening section described above.

In a preferred embodiment, an area of the reinforcement element is slightly smaller than the cover base area. In particular, this reduced size does not prevent the fastening elements that are fastened to the cover base surface from being folded over.

The reinforcement element preferably also has a size which enables it to be introduced into the inner cross-section of the packaging device formed by the side walls in an assembled state. The reinforcement element is therefore preferably surrounded by sections of the individual side walls of the packaging device in an assembled state of the packaging device.

The reinforcing element particularly preferably has the same or at least a similar geometric shape as the cover base area. So if the cover base is pentagonal, the reinforcing element is preferably also pentagonal. If the cover base is preferably designed to be square, the reinforcing element is preferably also designed to be square. The reinforcing element particularly preferably has rounded corners.

In a further advantageous embodiment, at least one and preferably at least two foldable tongues are arranged on the cover base surface. These tongues are preferably arranged on the edges of the cover base area and particularly preferably on opposite edges.

These tongues can preferably be used to enable such cartons to be stacked. In use, the tongues can be set up, for example, and inserted into corresponding recesses in a packaging device arranged above, in particular the same packaging device. These tongues are preferably arranged on at least one and preferably on both longitudinal sides.

The packaging device itself therefore particularly preferably has at least one and preferably a plurality of recesses, in particular in the base area, into which the said tongues can be inserted.

In a particularly preferred embodiment, at least two and preferably at least four such tongues are arranged on the lid base surface.

In a preferred embodiment, at least one tongue is formed within a recess. This recess preferably has a cross section that is larger than the cross section of the tongue, so that the tongue can be comfortably gripped with the finger can. Particularly preferably, the recess is arranged at least predominantly on the fastening sections.

In a further advantageous embodiment, a cover fastening section is shorter than the edge on which it is arranged. In this way it can be achieved that several cover fastening sections do not interfere with one another when they are folded down. A length of the deck fastening section is particularly preferably less than 98% of the length of the edge on which it is arranged, and preferably less than 95%.

However, the length of the fastening section is preferably more than 80% of the edge length on which it is arranged, preferably more than 85% and preferably more than 90%.

It should be noted that the embodiment proposed here with the fastening section and also with the tongues mentioned can also be claimed separately. The applicant reserves the right to do so.

The present invention is further directed to a kit for producing a transport packaging and / or an insulating packaging and in particular a transport packaging and / or an insulating packaging of the type described above. This has a foldable section which is used to form the transport packaging, this foldable section having at least four side walls connected to one another via folds, and wherein the first foldable section has at least a first floor section connected to at least one side wall.

The kit advantageously also has a cover unit. This cover unit has a cover base area as well as at least a first cover fastening section arranged on a first edge of this cover base area and a second cover fastening section arranged on a second edge of this cover base area, this first cover fastening section and the second cover fastening section each in a mounted state on the transport packaging or the transport packaging. Insulating packaging and / or the side walls can be fastened.

It is therefore also proposed here that the kit be designed in at least two parts, one part containing the packaging device and the other part its cover unit.

At least one section of the kit of at least the cover unit preferably has a coating of the type described above.

In a preferred embodiment, the fastening sections have an adhesive with which they can be arranged on the side walls.

The present invention is further directed to a cover unit for a transport packaging and in particular a transport packaging of the type indicated above.

According to the invention, the cover unit has a cover base and at least one first cover fastening section arranged on the first edge of this cover base and a second cover fastening section arranged on a second edge of this cover base, this first cover fastening section and the second cover fastening section being attachable to side walls of the transport packaging.

In a preferred embodiment, the first cover fastening section and the second cover fastening section each have an adhesive surface in order to fasten these cover fastening sections to side walls.

The cover unit described here can be arranged on different packagings or their base units.

The cover unit is preferably made from a paper or cardboard material. Furthermore, the cover unit is preferably designed in the manner described above.

The present invention is further directed to an insulating packaging, in particular for packaging portable objects, the insulating packaging having a bottom part which has at least three, preferably at least four side walls connected one above the other via a first fold and a first bottom section that can be closed by folding having, wherein this first bottom section is arranged on a second fold on a first side wall.

According to the invention, at least one further foldable section is arranged on the at least two side walls, this further foldable section having at least two foldable sub-sections with respect to one another, and one of these foldable sub-sections serving as a further side wall layer and the other of these foldable sub-sections serving as a further bottom layer.

This further section is preferably arranged on the side wall in such a way that the side wall is arranged between this further section and the above-mentioned bottom section.

In this embodiment, the above-mentioned coating is not necessarily provided. However, this is also advantageously provided.

A further section is preferably also arranged on at least one further side wall and preferably on the two remaining side walls, this section also preferably having a sub-section which serves as a further side wall layer and the other of these foldable sub-sections serves as a further bottom layer.

This configuration ensures that the entire base part is constructed with at least double walls, that is to say has both a double base and double side walls.

Said second sub-sections which form the second floor layer are particularly preferably designed in such a way that together they essentially cover the entire floor area. It is thus possible for the edges of these second subsections to rest against one another when they are folded together such that a closed or essentially closed bottom surface is created overall.

The multiple walls described here also achieve a higher insulation effect for the entire packaging device.

Transition areas are particularly preferably provided between at least one further foldable section and preferably between a plurality of foldable sections and particularly preferably between all foldable sections and the respective side walls on which these foldable sections are arranged. These transition areas are preferably connected both to the respective side walls and to the foldable sections via folds.

This transition area can have a predetermined width so that the finished packaging device also enables a predetermined distance between the above-mentioned side walls and the further side wall sections that are now present. In this way, a folded packaging device has a predetermined section between the side wall and the respective further side wall layer. This section can also be used for isolation purposes.

These transition areas are preferably delimited laterally by two folds

Figure 1 shows a kit or a pattern for producing a packaging device. The packaging device is created by folding the in Figure 1 shown pattern. Four side walls 24a, 24b, 24c and 24d can be seen. These are each folded around folds 26a to 26d, namely here at 90 ° with respect to one another. This creates a rectangular base area formed by the side walls 24a to 24d.

At the in Figure 1 The embodiment shown are each arranged on the left side of the side walls of the cover surfaces 28a to 28d. This means that the in Figure 1 embodiment shown, no separate cover unit is provided.

A bottom section 26b is arranged on the side wall 24b. This bottom section 26b extends here essentially along the width B of the side wall 24a. The bottom section 26b is thus suitable here for essentially covering or forming the entire bottom of the packaging device.

The reference symbol 52 denotes a desired kink or desired fold, with respect to which a corner section 54 can be bent relative to the main section 56. In this way, too, the unfolding of the folded cardboard box can be facilitated.

In an unfolded state of the packaging device or the assembled state, the bottom section 26a and in particular the corner section 72 of the bottom section 26a are preferably fastened to the bottom section 26b, in particular to its main section 56, by means of an adhesive connection. The corner section 72 is preferably connected to the main section 76 of the bottom section 26a via a fold 74.

In a similar way, the base section 26c also has a corner section 62 and a desired kink or desired fold 64, via which the corner section is arranged on the main section 66 of the base section.

The corner section 62 of the bottom section 26c is preferably also attached to the bottom section 26d via an adhesive connection.

Reference numeral 82 relates to a corner section of the base section 26d, which is arranged via a desired kink or desired fold 84 on the main section 86 of the base section 26d.

The desired kinks or desired folds shown here preferably each run in a straight direction.

The individual corner sections 54, 62, 72 and 82 are each preferably designed as right-angled triangular sections.

The reference numeral 30 denotes a fastening device by means of which the bottom section 26b can ultimately be fastened to the wall section 24d in an assembled state of the packaging device. The fastening device here has an adhesive film which is covered by a liner.

The reference numeral 34 denotes a further fold, with respect to which the section 32 can be bent or angled with respect to the base section. In an assembled state, the fastening section 30 is also bent at an angle of essentially 90 ° with respect to the bottom section 26b.

The reference symbols 17 identify recesses which are formed here on the one hand between the side wall 24b and the bottom section 26b and on the other hand between the side wall 24d and the bottom section 26d. Guide tongues, for example of an underlying packaging device, can be inserted into these recesses in an assembled state or in an assembled state of the packaging devices, in order to facilitate the stackability of a plurality of packaging devices.

The reference symbols 15 designate corresponding projections or noses which, when the packaging is in an assembled state, protrude upwards, for example, and can engage in the packaging device located above or the recess 17 present there.

The reference numeral 32 denotes an adhesive section which can be fastened to the side wall 24 in order to mount or assemble the packaging.

Reference numerals 28a to 28d denote stabilizing sections which are each arranged on the side walls. These stabilizing sections can be folded over during assembly and placed against the respective side walls, so that the side walls themselves are reinforced.

The stabilizing sections preferably have essentially the same area sizes as the side walls on which they are arranged. It would also be possible here for such a stabilizing section to be arranged only on one side wall or on two or three side walls.

Alternatively, cover sections for a cover device for a corresponding packaging can be provided at this point in a conventional manner.

Figure 2 shows a lid device 100, in particular in the case that the packaging device itself does not have any lid sections.

This lid unit 100 has a lid base area 102 which covers the packaging device. Four cover fastening sections 112, 113, 114 and 115 are arranged on this cover base area 102. These cover fastening sections are at the edges 102a. 103a, 104a and 105a of the cover base surface are arranged pivotably. At the same time, these edges also form folds 132, 133, 134 and 135.

The fastening sections each have a fastening element 122, 123, 124 and 125. These can be glued to the respective side walls of the packaging device.

Here, too, cover films are again provided which cover an adhesive layer so that the user can remove this film in order to then attach the fastening section to the respective side wall. The reference character B denotes the width of the lid base area and the reference character L its length.

The reference numerals 140 denote lugs which, for example, when the cover unit is in an assembled state, can be folded up and can engage in corresponding recesses in the packaging device arranged above.

These tongues 140 are formed here within recesses 142. These recesses 142 are predominantly arranged within the respective fastening sections 112 to 115. It can be seen that the recesses are slightly larger or have a slightly larger area than the tongues 140. This makes it easier for a user to fold out the tongues.

The reference symbols 105 identify recessed grips with which the packaging can be carried. It is possible that the side walls of the associated packaging device also have such recessed grips so that the user can better grip the packaging through both recessed grips.

The reference symbols 152, 153, 154 and 155 denote tear-open points at which the fastening incision can be separated. In this case, these tear-open points can be gripped using grip elements 157, for example. In this way, the packaging can be opened on all sides if desired. In this way, a one-way opening is also made possible, that is, further closing with the same cover is no longer possible. In this way, for example, proof of opening of the packaging can also be provided.

The reference symbol T2 denotes a depth of the fastening section and thus the area at which this fastening section extends down on the packaging device or its side walls in a closed state.

The reference symbol LS denotes the entire length of the in Figure 2 Cutting pattern shown and the reference character BS its entire width.

Figure 3 FIG. 4 shows a detailed view of the cover unit 100. The cover base area 102 is shown again, but without the FIG Figure 2 mounting sections shown. A fastening element 110, for example another cardboard box, is arranged on this cover base surface 102.

It can be seen that both the length L 110 and the width B 110 are slightly smaller than the length L and the width B. This reinforcing element 110 increases the overall stability of the cover unit.

The Figures 4 and 5 show two representations of a packaging device 1 in an assembled state. The side walls 24a to 24d can also be seen here as well as the bottom section 26b and the fastening section 32, which can be fastened here to the opposite inner surface of the side wall 24d. At the in Figure 5 In the illustration shown, the bottom sections 26a, 26c and 26d present below the bottom section 26b can also be seen. These have various folds (as explained above) in order to facilitate unfolding of the packaging box.

In addition, the projections 17 are also marked again, which serve to engage in the recesses 15 of a packaging device correspondingly above it.

The Figures 6 and 7 show two representations of a cover unit 100. Here again the cover base area 110 is shown, on which the four fastening sections 112 to 115 are arranged. In addition, the reinforcement device 110 is also shown, which is glued to the cover base surface 102.

At the in Figure 7 The illustration shown here also shows the tongues 140, as well as the recesses 142, within which they are arranged.

Figure 8 shows a further embodiment of a transport packaging according to the invention. In this embodiment according to the invention, too, there are four side walls 24a-24d. In this embodiment, a bottom section 26b is again arranged on the side wall 24b.

In contrast to the configurations shown above, two further holding sections 58a and 58b are arranged here on this bottom section, each via folds 57a and 57b. These holding sections can be placed against the side walls 24a and 24c in an assembled state of the transport packaging. Adhesive points can be provided in order to fasten these holding sections 58a and 58b to the side walls.

The two holding sections 58a and 58b each have recesses which, in an assembled state of the transport packaging, are essentially congruent with the openings 35. To transport the transport packaging, the user can reach with his hand both through the opening 35 and through the opening 37 and thus carry the transport packaging and at the same time stabilize the floor.

Reference numeral 38 denotes a recess which is arranged in the bottom section 26d. The user can reach into this recess with his finger in order to move the base section 26d.

Figure 9 shows a further embodiment of a transport packaging. In this embodiment, the recesses 17 already described above and the projections or tongues 15 are also present, which in particular also facilitate the stacking of several transport packaging on top of one another.

Figure 10 shows a schematic representation of a coating. The reference symbol 120 identifies a specific section of the packaging device. The reference numerals 120a and 120b identify the opposing surfaces of this section 120. A total of three layers 182, 184 and 186 are applied to this section, these layers each containing a metal and in particular silver especially a paste containing silver. A protective layer 190, such as in particular, but not exclusively, a lacquer is applied above the layer 186. The reference numeral 180 denotes the coating as a whole.

At the in Figure 10 In the illustration shown, the coating is only shown on surface 120a. However, the coating is preferably also present on the opposite surface 120b.

As mentioned above, the layer is preferably applied here in a flexographic printing process. However, it would also be possible for the coatings to be applied in a so-called preprint process or in a flexo roll preprint process. It is possible here for the base material 120, for example the paper or cardboard, to be precoated in a flexographic printing process. Subsequently, this base material or the section 120 can be used as an inner ceiling or outer ceiling and, for example, glued to a corrugated material.

This can also be done with a coating. In general, a flexopreprint process is used to print paper webs from roll to roll. With this method, large editions in particular can also be produced efficiently. It is possible that a cover paper is first printed on a separate multicolor printing machine and then used as the outer cover in a corrugated board system. Further processing can then take place on conventional corrugated cardboard processing machines.

A corrugated cardboard system can, for example, be a combination of several system parts, these system parts being able to have their own drives, for example, with the individual drives being able to be regulated independently of one another. Such corrugated cardboard plants can produce corrugated cardboard with smooth covers.

Figure 11 shows a further design of a bottom part of a packaging device. This packaging device is similar to the one in Figure 8 bottom unit shown. In contrast to this, however, further foldable sections 170a, 170b, 170c and 170d are arranged on the side walls 24a, 24b, 24c and 24d. These foldable sections have it first subsections 172a, 172b, 172c and 172d, and second subsections 176a, 176b, 176c and 176d. The first sub-sections 172a, 172b, 172c and 172d serve in a folded state as further layers of the respective side walls. The second sub-sections 176a, 176b, 176c and 176d serve as second layers of the floor section and together form approximately the area of the complete floor. In this way, a double-layer floor is also created.

The reference numerals 173b and 173d denote folds which are arranged between the first subsections 172b, 172d and the subsections 174b and 174d. These further sections then overall facilitate the folding of the sub-sections 172b and 174b relative to one another. The reference symbols 175a, 175b, 175c and 175d identify further folds with which the second sub-sections 176a-d can be folded with respect to the first sections 172a-d. In this way, the subsections can be folded inwardly into the packaging device.

Figure 12 shows an illustration of the above-mentioned insulating ring 300. This insulating ring 300 here has a total of five sections 302, 304, 306, 308 and 310, which are each connected to one another via folds. In this way, the insulating ring can be folded into a rectangular shape and inserted, for example, between the layers of the side walls during the assembly of the packaging device. In this way, a triple layer of the side walls can be achieved overall.

Figure 13 shows a representation of an inner packaging with which a coolant can be introduced into the packaging device. This inner packaging 200 has a bottom section 202 and a lid section 210. In addition, side wall sections 204, 206, 208 and 212 are provided. In the cover section 202, openings 230 are provided, via which a heat exchange can take place.

The reference numerals 222 identify adhesive sections which are used to glue the inner packaging. The reference numerals 224 and 226 also relate to corresponding connecting sections.

Figure 14 FIG. 13 shows a further illustration of a cover unit similar to that shown in FIG Figure 2 is shown. A key difference is that the in Figure 14 The cover unit shown has no further slots or openings in order to improve the insulation effect.

In addition, however, a reinforcement plate 102 is also provided here.

Figure 15 shows a further illustration of a reinforcement plate 400. This has a basic cutout 402 and here two adhesive strips 404 and 406, by means of which on this cover unit or on the plate the in Figure 13 inner packaging shown can be glued on. The reference symbols 408 relate to peripheral edges or positioning edges which are used to position the inner packaging on the surface 402.

The applicant reserves the right to claim all features disclosed in the application documents as essential to the invention, provided that they are new to the state of the art, individually or in combination. It is further pointed out that features have also been described in the individual figures which can be advantageous in themselves. The person skilled in the art immediately recognizes that a certain feature described in a figure can also be advantageous without the adoption of further features from this figure. Furthermore, the person skilled in the art recognizes that advantages can also result from a combination of several features shown in individual or in different figures.
