Description

Partial shell for packaging a food product, packaging a food product and packaged food product

The present invention relates to a food package or a packaged food product, which is included in the food package according to the invention. According to one aspect of the invention, this relates at least to a partial shell with which such a packaging is formed.

Packaging packaging plays an important role in providing food today. In addition to printing can be achieved by choosing appropriate packaging materials a quality feel. A method in which a chocolate hollow figure is packaged by means of a package of two half-shells is known, for example, from EP 2 765 081 A1. The process described in this document is the process by which today's known surprise eggs are packed. In the method described in EP 2 765 081 A1, a chocolate hollow body is inserted in a first step into a recess of a half-shell, which has a flange bounding the recess. After the chocolate hollow body has been inserted into the recess of the first half-shell, a similar second half-shell is placed with a circumferential flange on the inserted chocolate hollow body, so that the flanges of the respective half-shell lie flat against each other and form a peripheral and projecting edge portion. In order to seal the cavity, which is formed by the two depressions of the half-shells, a sealing line is generated circumferentially at the protruding edge portion, between the opposing flange portions with a hot punch. Thereafter, the protruding circumferential edge is trimmed and folded back on itself by means of a so-called beading, so that a proximal edge portion is spaced over a fold line from a distal edge portion. The hollow chocolate body lies contour-forming, in particular full-surface on the inner walls of the cavity and the corresponding half-shells form the Schokoei contour accurate.

The same method as described in EP 2 765 081 A1 can also be used for the production of packaged St. Nicholas, Easter bunnies or any other packaged food products.

A package of two half-shells, in which the food is inserted exactly contoured, is described in DE 10 201 1 002 754 A1. The two half-shells are in this case made of aluminum foil, which is coated on the inside with a thermoplastic material. When heated in the superimposed and adjacent Flange areas a full-surface seal in the protruding edge area is achieved.

Based on the described packaging, it is an object of the present invention to produce very interesting packaging for the customer, so that they positively influence the customer in his purchase decision.

To solve the problem described above, the invention proposes seven novel types of packaging or partial dishes, the individual aspects of which can also be combined with one another in any unrestricted combination.

According to a first aspect of the invention, there is provided a food package having a first subshell containing a first recess and a first flange defining the first recess; a second subshell containing a second recess and a second recess defining the second recess; wherein the first and second sub-shell are coupled together via their flanges and thus form a cavity for receiving a food. This food packaging according to the first aspect is characterized in that the first sub-shell is made of a different material from the second sub-shell. In the designation of different materials, the view is taken that at least the outer surface or parts of the outer surface of a first partial shell is different from the outer surface or parts of the outer surface of a second partial shell. According to an advantageous development of the invention, the different materials of the partial shells can be selected from the group of the following materials: metal, paper, plastic. The term "metal, paper or plastic" is based on the corresponding surface layer, ie, if different materials are used, at least different surface materials of the corresponding sub-shells are used.A multilayer material, for example a laminate laminated with plastic film, can also be used The partial shells have a different material, even if they have superficially different materials.

Examples of plastic materials are thermoformable plastic film materials such as polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS), polyester. These film materials preferably have the following strengths: 80 μm, 100 μm, 120 μm, 140 μm, 150 μm, 170 μm, 200 μm, 350 μm, 375 μm, 500 μm, 520 μm, 700 μm. The above-mentioned strengths can in each case in each case combinations lower or upper limits of a form preferred strength range. In particular, a range of 80 to 375 μm is preferred.

Heretofore, food packaging, as far as they are made of plastic, has been made of conventional plastics, in particular non-biodegradable thermoplastics, such as e.g. Polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS).

The recovery rate of such conventional plastic materials is often insufficient. To address this problem, new compostable materials with similar barrier properties can be used. Examples of such biodegradable plastic materials, the raw materials from which they are made, and their raw material are shown below:

Material: polyhydroxyalkanoate, e.g. Polyhydroxybutylate (PHB), polyhydroxyvinylate (PHV); Raw material: starch, sugar; Basic material: starch, sugar.

Material: polylactide (PLA); Raw material: corn starch; Basic material: lactic acid.

Material: thermoplastic starch or starch blends; Raw material: potato,

Wheat, corn; Basic material: starch.

Material: cellophane; Raw material: wood; Basic material: cellulose. Material: degradable polyester.

Materials are referred to as biodegradable, if by microorganisms, or enzymes z. B. be mined in the ground. The degradation takes place mainly through oxidation and hydrolysis processes to the fission products water, carbon dioxide and biomass. In addition to various plastics made from renewable raw materials (bioplastics), the aforementioned definition also includes petroleum-based materials such as polyvinyl alcohols, polycaprolactones or certain copolyesters (for example PBAT: Ecoflex from BASF or Ecoworld from JinHui Zhaolong). However, not all bioplastics based on renewable raw materials are necessarily biodegradable (e.g., vulcanized rubber).

The term "biodegradable" is to be distinguished from polyolefin films (in particular PE) which are sometimes used in the packaging industry and which are declared as "oxo-biodegradable" or "oxodegradable.""Oxo-degradable" additives are usually metal ions (cobalt, manganese , Iron, zinc) which reduce the oxidation and chain degradation in plastics, especially under Heat, air and oxygen, accelerate. The results of this chain degradation are very small, barely visible chain fragments that do not biodegrade (none of the additive manufacturers has so far been able to provide data), but move through our food chain. In the narrower sense (especially in the field of biomedicine) are referred to as biodegradable materials that are degraded in the body by macrophages, enzymes or hydrolysis within days to a few years. These include, in particular, biogenic polymers such as collagen, fibrin or hyaluronic acid, but also polylactic acid (polylactide), polyglycolide and polycaprolactone. All of the aforementioned materials, which are broadly referred to as biodegradable, may find use. In particular, it is advantageous that these biodegradable materials are also biomaterials from renewable raw materials.

Examples of paper materials are chromo carton, fully bleached pulp, pulp paper, sugarcane paper, thermo-formable fiber material (active polyvalent packaging based on environmentally friendly fibrous material). In particular, thermoformable paper can be used. A thermoformable paper material is a material which, under the action of heat, can be transformed in a forming device, for example between two mold halves, such as a stamp which is pressed into a cavity, as is known per se for thermoplastics. Such thermoformable paper materials have recently been used in some specialized fields. In particular, was used as a thermoformable paper material, a paper material of the company Billerudkorsnäs named "FIBER FORM ^®", which was produced in 2016. The paper thermoformable material may contain hydrophobic cellulose.

These film materials preferably have the following strengths: 80 μm, 100 μm, 120 μm, 140 μm, 150 μm, 170 μm, 200 μm, 350 μm, 375 μm, 500 μm. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 80 to 500 μm is preferred. The paper materials are sometimes thicker than the plastic film materials.

Examples of metal foil materials are aluminum foil, stainless steel foil, copper foil. These film materials preferably have the following strengths: 12 μm, 15 μm, 18 μm, 20 μm, 25 μm, 30 μm, 50 μm, 70 μm, 100 μm, 200 μm. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 12 to 200 μm is preferred. The Metal foil materials are sometimes preferably thinner than the plastic film materials.

Different multilayer materials can also be used. As far as the invention is geared to a film material, however, it should contain a film material layer; as soon as the invention turns off a different film material from a metal foil material, no metallic foil components should be contained in each case.

Since, in the further processing of the partial packing shells produced according to the invention, these are joined to each other, in particular after inserting a food product, at their flange regions, it is advantageous to use coated metal foil materials which have a plastic coating. This is later sealed and contributes to a tight connection of the packaging part shells. As a sealable metal foil, a film with a low-density polyethylene (LDPE) coating may be provided. The other aforementioned plastic materials may also be provided as an alternative or in addition to the LDPE coating. The thickness of the individual layers can be selected from the abovementioned strengths of the individual materials. Also suitable as a sealable coating is a so-called "hotmelt" coating, which is a hot melt adhesive, depending on the application, of a different composition Hotmelt can be applied either over the film or partially before closing the partial packaging shell.

According to a development, the opposing flanges of the partial shells can be connected to one another by sealing and / or flanging and / or embossing and / or applying. In this case, crimping is formed on folding back the protruding edge of the opposing flanges, so that a proximal edge portion is spaced over a fold line from a distal edge portion. Embossing is a three-dimensional deformation of the flange area, so that mutually opposite flange areas interlock and thus hold together better. A seal describes z. B. an adhesive connection or an adhesive connection between the flanges. An application describes such a buckling of the protruding edge portion at the bend line for recessing the partial shell, so that the protruding edge, which may be crimped or not crimped, rests against the outer surface of the package. The above-described methods for coupling the partial shells can be used in combination with each other.

According to one embodiment of the invention, the flange may be integrally provided on the recess. The flange and the recess go at the bend line in particular into each other and are not built over the break line of different materials, so that the flange is a separate element from the depression.

According to one embodiment of the invention, the partial shell can be completely limited by the flange. If the flange is connected to produce a food packaging with another flange of a second sub-shell, forms by the flanges a protruding edge in the manner of a saturn-like ring that can surround the food packaging in full. This protruding edge can be crimped on its own or can also be unshackled. This protruding edge can also be applied to the outside of the package. Insofar as it is placed on partial shells, the point of view is that packaging can also be made up of more than two partial shells. All shells provide a complete package. As far as the packaging is formed only by two partial shells, these partial shells can also be seen as half shells.

According to a secondary aspect, there is provided a packaged food product, wherein a package as described above for the first aspect of the invention is provided. The packaged food product is characterized in that the recesses provided on the partial shells form a cavity for receiving the food, so that the food rests on the inner walls of the cavity in a contour-shaping manner, in particular over the whole area. In this packaging, the food lies with its outer surface in particular positively in the cavity and the corresponding sub-shells contour contouring, in particular over the entire surface of the food.

Such a food may be a chocolate body, in particular chocolate hollow body, for. B. act in the shape of a Santa Claus or Easter Bunny.

According to a second aspect of the invention, this proposes a partial shell for packaging a food product, with a depression and a flange delimiting the depression, via which a further partial shell can be coupled to form the packaging. This sub-shell is characterized in that a window made of a first material is provided in the sub-shell, which is different from a second material which forms at least one outer surface of the sub-shell. This window is made of a material different from the part shell surface. The window may also be made in the manner described for the fourth aspect of the invention. As a window, a material can be used, which is transparent. This is not necessary. Any material may be used for the outer surface of the package and the surface of the window. As materials metal, paper or plastic can be used. The term "metal, paper or plastic" is based on the corresponding surface layer, ie, if different materials are used, at least different surface materials of the corresponding sub-shells are used.A multilayer material, for example a laminate laminated with plastic film, can also be used The sub-shells have a different material even if they have superficially different materials, ie, for example, one segment of the sub-shell may have one surface of paper and one inner surface of a plastic film laminated with the paper and another segment the same multilayer material is used, in which case the plastic film is provided on the outside and the paper on the inside, and paper is also understood to mean cardboard.

Examples of plastic materials are thermoformable plastic film materials such as polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS), polyester. These film materials preferably have the following strengths: 80 μm, 100 μm, 120 μm, 140 μm, 150 μm, 170 μm, 200 μm, 350 μm, 375 μm, 500 μm, 520 μm, 700 μm. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 80 to 375 μm is preferred. Heretofore, food packaging, as far as they are made of plastic, has been made of conventional plastics, in particular non-biodegradable thermoplastics, such as e.g. Polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS). The recovery rate of such conventional plastic materials is often insufficient. To address this problem, new compostable materials with similar barrier properties can be used. Examples of such biodegradable plastic materials, the raw materials from which they are made, and their raw material are shown below:

(PHV); Raw material: starch, sugar; Basic material: starch, sugar.

Material: thermoplastic starch or starch blends; Raw material: potato,

Wheat, corn; Basic material: starch.

Materials are said to be biodegradable when contaminated by microorganisms or enzymes, e.g. be degraded in the soil. The degradation takes place mainly through oxidation and hydrolysis processes to the fission products water, carbon dioxide and biomass.

In addition to various plastics made from renewable raw materials (bioplastics), the aforementioned definition also includes petroleum-based materials such as polyvinyl alcohols, polycaprolactones or certain copolyesters (for example PBAT: Ecoflex from BASF or Ecoworld from JinHui Zhaolong). However, not all bioplastics based on renewable raw materials are necessarily biodegradable (e.g., vulcanized rubber).

The term "biodegradable" is to be distinguished from polyolefin films (in particular PE) which are sometimes used in the packaging industry and which are declared as "oxo-biodegradable" or "oxodegradable." "Oxo-degradable" additives are usually metal ions (cobalt, manganese , Iron, zinc), which accelerate oxidation and chain degradation in plastics, especially under heat, air and oxygen.

Examples of paper materials are chromo carton, fully bleached pulp, pulp paper, sugarcane paper, thermo-formable fiber material (active polyvalent packaging based on environmentally friendly fibrous material). In particular, thermoformable paper can be used. A thermoformable paper material is a material which, under the action of heat, can be transformed in a forming device, for example between two mold halves, such as a die, which is pressed into a cavity, as is known per se for thermoplastics.

In particular, as thermoforming bares paper material, a paper material of the company Billerudkorsnäs named "FIBER FORM ^®", which was produced in 2016, used the thermoformable paper material may contain hydrophobic cellulose This film materials preferably have the following strengths:.. Μηη 80, 100 μηη, 120 μηη, 140 μηη, 150 μηη, 170 μηη, 200 μηη, 350 μη ", 375 μηι", 500 μηη The above-mentioned starches may in each case in each case form lower or upper limits of a preferred range of strengths The paper materials are sometimes thicker than the plastic film materials.

These film materials preferably have the following thicknesses: 12 μm, 15 μm, 18 μm, 20 μm, 25 μm, 30 μm, 50 μm, 70 μm, 100 μm, 200 μm. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 12 to 200 μm is preferred. The metal foil materials are sometimes preferably thinner than the plastic film materials.

According to an advantageous embodiment of the invention, the partial shell can be made of a different material sheet than the window, wherein the window is inserted as a laying element back into the partial shell. The partial shell is z. B. formed in a thermoforming device or forming device. In a blank shell, the z. B. has a window opening, then an insert element can be inserted into the window opening. However, the window can already during the forming, if z. B. two material sections are supplied simultaneously and at least partially overlapping the forming device can be produced. The window may also already be provided in the manner described for the fourth aspect of the invention as integral with the material supplied.

According to an advantageous development of the invention, the partial shell can be formed from a multilayer material, and the window can be formed by a lower layer laminated together with an outer surface layer. Thus, the partial shell may be formed of an at least two-ply material having a first surface layer and a second layer provided underneath and the window opening formed by the first surface layer and the window through the underlying layer, which z. B. is laminated over the entire surface with the first surface layer. There may also be more than two layers, but the uppermost layer has one or more Window openings through which at least underlying layers or one of the underlying layers is visible.

According to one embodiment of the invention, the window may be provided in the region of the depression and not protrude into the flange. According to one embodiment of the invention, a plurality of windows may be provided in the partial shell.

According to one embodiment of the invention, the window may have a geometry selected from the following group: circle, oval, rectangle, heart, star, flower, person.

According to a development of the invention, the window can be provided with different geometries in the partial shell.

According to one embodiment of the invention, the different materials for the partial shell or for the window can be selected from the group of the following materials: metal, paper, plastic. For the materials, reference is made to what has been said about the fourth aspect in relation to the materials. According to one embodiment of the invention, the flange may be integrally provided on the recess. The flange and the recess in particular merge into one another at the bend line and are not constructed over the break line of different materials, so that the flange is a separate element from the depression.

According to one embodiment of the invention, the partial shell can be completely limited by the flange. If the flange is connected to produce a food packaging with another flange of a second sub-shell, forms by the flanges a protruding edge in the manner of a saturn-like ring that can surround the food packaging in full. This protruding edge can be crimped on its own or can also be unshackled. This protruding edge can also be applied to the outside of the package.

Only one of the partial shells can be a partial shell with the features described above. The second subshell and each additional subshell may be used without limitation, e.g. B. also from a single sheet of a single material or a multilayer material. Insofar as it is placed on partial shells, the point of view is that packaging can also be made up of more than two partial shells. All shells provide a complete package. As far as the Packaging is formed only by two shells, these shells can also be seen as half shells.

According to a sidelined aspect, a food package with at least two partial shells, which are coupled to each other via a provided on the respective sub-shell flange, indicated. This food packaging is characterized in that at least one of the partial shells is a partial shell with the window previously described for the second aspect.

According to one embodiment of the invention, only one of the partial shells may be a partial shell with the features described above. The second subshell and each additional subshell may be used without limitation, e.g. B. also from a single sheet of a single material or a multilayer material. Insofar as it is placed on partial shells, the point of view is that packaging can also be made up of more than two partial shells. All shells provide a complete package. As far as the packaging is formed only by two partial shells, these partial shells can also be seen as half shells.

According to one embodiment of the invention, the partial shells can be provided with the same material distribution. A same material distribution means that the windows are arranged symmetrically in the subshells, so that after coupling the two subshells, a surface symmetry is provided with respect to the individual segments of materials. The symmetry surface is z. B. by the parting plane, which is formed between the opposite flanges of the different sub-shells provided.

According to a further independent aspect, a packaged food product is provided, wherein a package is provided from partial shells, wherein the recesses provided in the partial shells form a cavity for receiving the food and the food contour forming, in particular all over the inner walls of the cavity rests. Thus, the food lies with its outer surface in particular positively in the cavity and the corresponding sub-shells contour contouring, in particular over the entire surface of the food. At least one of the partial shells used should be one of the partial shells with the flange regions made of different materials, which was previously described for the third aspect.

Such a food may be a chocolate body, in particular chocolate hollow body, for. B. act in the shape of a Santa Claus or Easter Bunny. According to a third aspect of the invention, a partial shell for packaging a food product having a depression and a flange bounding the depression, via which a further partial shell can be coupled to form the packaging, is provided. The partial shell is characterized in that the flange has a first region of a first material and a second region of a second material, which is different from the first material.

For such areas, it is sufficient that only the surface of the flange has different materials. This view is effective when the partial shell is made of a multilayer material. In particular, however, different material sheets can also be used to produce the same for the individual regions of the flange.

For the first time it could be shown by experiments that a coupling of partial shells over the flanges is still tenable even if areas of different material are connected by opposing flanges. According to one embodiment of the invention, the first and second flange region adjoin one another at a joint line. At this joint line, the two flange areas collide. The joint line may extend from the flange over the region of the subshell in which the depression is formed, and from there via a further flange section, which is, for example, separated from the first flange section. At such a joint line different layers of material can also be arranged overlapping. At the interface, at least surface areas of different materials collide. The joint line can also be constructed by a plurality of joint lines or by joint segments which are provided in different regions of the sub-shell.

According to an advantageous development of the invention, the joint line can extend transversely across the flange from a transition between the flange and the recess to a distal edge of the flange delimiting the partial shell. The transition can be formed by a bending line provided between the recess and the flange, wherein a proximal portion of the flange protrudes from the bending line and a distal part of the flange forms the boundary of the partial shell. A profile transverse to the flange denotes a course of the joint line not parallel to the course of the flange or of the edge bounding the flange. Such a transverse course of the joint line can also be a vertical course of the joint line, perpendicular to the protruding edge section or the edge bounding the subshell. According to an advantageous embodiment of the invention, the joint line may have a non-straight course at least in the region of the flange. A non-linear course can be any chosen course.

According to an advantageous development of the invention, at least two joint lines can be provided at different flange areas. The two joint lines can be connected via a third joint line, which connects the two joint lines with each other, so that only a single joint line is formed from three sub-segments. This joint line of three sub-segments runs z. Example, via a first flange portion, over a portion of the sub-shell with the recess and a second flange portion which is spaced over the region of the recess of the first flange portion.

According to an advantageous development of the invention, the at least two lines of contact can be provided in alignment with one another on different sides of the recess 305. If the joint lines are arranged in alignment with one another, the simplest possible production is possible. Advantageously, these two ridge lines may be interconnected by the third ridge line in the area of the recess and form a single straight line of three line segments.

According to an advantageous development of the invention, the first and / or the second material can be selected from the group of the following materials: metal, paper plastic. As materials metal, paper or plastic, in particular plastic film can be used. The term "metal, paper or plastic" is based on the corresponding surface layer, ie the different materials are at least different surface materials of the corresponding sub-shells.A multilayer material can also be used, for example a paper sheet laminated with plastic film Partial shells also have a different material if they have superficially different materials, ie, for example, one segment of the partial shell may have a surface of paper and an inner surface of a plastic film laminated with the paper, and the same multilayer material may be used for another segment In this case, the plastic film is provided on the outside and the paper on the inside, and paper is also understood to mean cardboard.

Examples of plastic materials are thermoformable plastic film materials such as polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS), polyester. In particular, polyesters are used for cost reasons to provide a low cost To produce packaging. These film materials preferably have the following strengths: 80 m, 100 m, 120 μm, 140 μm, 150 μm, 170 μm, 200 μm, 350 μm, 375 μm, 500 μm, 520 μm, 700 μm. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 80 to 375 μm is preferred.

Heretofore, food packaging, as far as it is made of plastic, has been made of conventional plastics, in particular non-biodegradable thermoplastics, such as e.g. Polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS).

These include v.a. biogenic polymers such as collagen, fibrin or hyaluronic acid, but also polylactic acid (polylactide), polyglycolide and polycaprolactone.

All of the aforementioned materials, which are broadly referred to as biodegradable, may find use. In particular, it is advantageous that these biodegradable materials are also biomaterials from renewable raw materials.

As far as the invention is geared to a different material from a first material, should be provided in each case, at least superficially, areas of different materials. At least on the packaging surface, different regions / regions / sections of different materials are provided.

Coated metal foil materials having a plastic coating may also be used, which will later be sealed and contribute to a tight connection of the partial packaging shells. As far as, for example, ethylene-vinyl alcohol copolymer (EVOH) is used as a coating, a gas-tight seal and thus z. B. also be provided packaging. It may be used for a gas-tight packaging, any other known material which ensures a gas-tightness. As a sealable metal foil, a film with a low-density polyethylene (LDPE) coating may be provided.

According to one embodiment of the invention, the flange may be integrally provided on the recess. The flange and the recess in particular merge into one another at the bend line and are not constructed over the break line of different materials, so that the flange is a separate element from the depression.

According to one embodiment of the invention, the partial shell can be completely limited by the flange. If the flange is connected to produce a food packaging with another flange of a second sub-shell, formed by the flanges a protruding edge in the manner of a saturn-like ring of z. B. the contour of the figure follows, which can fully surround the food packaging. This The protruding edge can be crimped on its own, or it can also protrude without being bound. This protruding edge can also be applied to the outside of the package. Such beading can also be combined with a sealing of the edge or else be carried out without sealing the edge. It can also be provided only a seal without crimping and / or mooring.

The partial shell described above can be provided according to a further aspect of the invention in a food package with at least two partial shells, which are coupled to each other via a provided on the respective partial shell flange.

According to one embodiment of the invention, the partial shells can be provided with the same material distribution. A same material distribution means that the individual segments are arranged symmetrically in the subshells, so that after coupling the two subshells an area symmetry is provided with respect to the individual segments of materials. The symmetry surface is z. B. by the parting plane, which is formed between the opposite flanges of the different sub-shells provided.

According to a sidelined aspect, a packaged food product is provided, wherein a package is provided from partial shells, wherein the recesses provided in the partial shells form a cavity for receiving the food and the food substantially Konturbildbildend, in particular over the entire surface or approximately over the entire surface of the inner walls of the cavity is applied. A contour-imaging system can be a full-surface system that depicts the contour of the food. However, such a plant does not exclude narrowly defined sections in which the packaging tray is a small distance from the food surface. Such a distance between the packaging inner wall and the food surface may be present, for example, in areas in which different geometries of the food meet, for example in the face of a food designed as a figure in the area where the eyes and nose meet and / or in the area of the transition between hand and arm. Such a distance may also occur in sections of the food surface with small radii or high bending. The distances can be up to 1 μηη, 50 μηη, 1 mm, 5 mm, or even up to 10 mm. The aforementioned distances can each form upper and lower limits of the distance range. Large distances of 5mm or even up to 10mm may be provided, for example, to avoid tearing the paper elsewhere.

As far as in the present application is focused on konturabbildend or full area, the viewpoint described above takes effect. Thus, the food lies with its outer surface in particular positively in the cavity and the corresponding sub-shells are the entire surface of the food. At least one of the partial shells used should be one of the previously described partial shells with the flange regions made of different materials.

In such a food may be a chocolate body, in particular chocolate hollow body, z. B. act in the shape of a Santa Claus or Easter Bunny.

According to a fourth aspect of the invention, a sub-shell for packaging a food product with a recess and a recess bounding the flange, via which a further sub-shell can be coupled to form the packaging is specified. The partial shell according to the fourth aspect is characterized in that the partial shell is formed by deep drawing and the deep-drawing material is already supplied in a segmental configuration for forming, so that the partial shell has at least two surface segments of different materials.

Deep drawing can be done in a forming tool, as described for example in German Patent Application Az. 10 2016 216 444.9. The disclosure of this application is incorporated by this reference in the present application.

For a segment-like embodiment, the view is taken that at least the surface segments have different materials. It is not necessary for the corresponding subshells in the cross-sectional direction (material thickness direction) to have different layers in the region per se.

For example, various surface segments can also be provided by the fact that in a multilayer material only the topmost layer z. B. is partially cut out. The procedure, namely that the material is supplied in the configuration in which it is later formed into partial shells, can also be seen later on the partial shell itself. Because it makes a difference whether the individual segments are only connected after forming the partial shells, during the forming of the partial shell in the cavity, or even before. It can also be seen on the partial shell itself, whether it was made of a sheet of material or a piece of material film, which is unwound from a roll.

According to one embodiment of the invention, the partial shell may be formed of an at least two-ply material having a first surface layer and a second layer provided underneath and the first surface segment formed by the first surface layer and the second surface segment through the underlying layer, which with the first surface layer is laminated over the entire surface.

According to an advantageous embodiment of the invention, the first surface segment may be formed by a first material portion and the second surface segment by a second material portion, wherein the first and the second material portion are connected together at the edges thereof. The different material sections can be connected to each other at the edge, so that they overlap marginally a little or are only bumped. This is different from the aforementioned embodiment of a full-surface lamination with a lower layer and a segment-like upper layer. In essence, the individual material sections form the individual segments. According to an advantageous development of the invention, the segment-like configuration of the deep-drawing material may be formed by at least one surface strip of a first material and a surface strip of a second material which is different from the first material, wherein the surface strips are parallel to each other. The deep-drawing material preferably has a configuration in which side-by-side surface strips are formed. Surface stripes are superficial segments of different materials. What the individual layers of material below in the cross-sectional direction look like is not specified here. This stripy material can then be supplied as a whole of the forming device and be transformed into this. Depending on how the mold is aligned with respect to the strips, the course of the strips in the corresponding partial shells is different. So it may be that the stripes across the subshells run or even a partial shell is formed, are contained in the two segments of different materials. This is z. As is the case when the supplied surface strips are so large that the shape only ever forms the partial shell between two strips. According to an advantageous development of the invention, a plurality of surface strips of the first and a plurality of surface strips of the second material may be provided, which run alternately next to one another and parallel to one another. Not only can two different surface stripes be provided, but also a plurality of surface stripes of different density. These surface strips can run transversely to the feed direction of the material to be supplied or along it.

According to an advantageous development of the invention, the segment-like configuration of the deep-drawing material can be formed by an arc of a first material, in which at least one material window of a second material, which is different from the first material, is formed. In addition or as an alternative to the aforementioned strip-type configuration, the embodiment can also have window-like segments. Examples of angular material windows are star-shaped, square, in particular square shapes. Examples of roundish shapes are oval or circular shapes.

According to one embodiment of the invention may be provided in the sheet a plurality of material windows.

According to a development of the invention, the material windows can form a regular recurrent pattern.

Materials are said to be biodegradable when contaminated by microorganisms or enzymes, e.g. be degraded in the soil. The degradation takes place mainly through oxidation and hydrolysis processes to the fission products water, carbon dioxide and biomass. In addition to various plastics made from renewable raw materials (bioplastics), the aforementioned definition also includes petroleum-based materials such as polyvinyl alcohols, polycaprolactones or certain copolyesters (for example PBAT: Ecoflex from BASF or Ecoworld from JinHui Zhaolong). However, not all bioplastics based on renewable raw materials are necessarily biodegradable (e.g., vulcanized rubber).

The term "biodegradable" is to be distinguished from polyolefin films (in particular PE) which are sometimes used in the packaging industry and which are declared as "oxo-biodegradable" or "oxodegradable.""Oxo-degradable" additives are usually metal ions (cobalt, manganese , Iron, zinc), which reduce the oxidation and chain degradation in plastics, especially under Heat, air and oxygen, accelerate. The results of this chain degradation are very small, barely visible chain fragments that do not biodegrade (none of the additive manufacturers has so far been able to provide data), but move through our food chain. In the narrower sense (especially in the field of biomedicine) are referred to as biodegradable materials that are degraded in the body by macrophages, enzymes or hydrolysis within days to a few years. These include, in particular, biogenic polymers such as collagen, fibrin or hyaluronic acid, but also polylactic acid (polylactide), polyglycolide and polycaprolactone.

By means of the described crimping, in particular the geometry of the folding line can be selected independently of the geometry of the cavity in the region of the parting plane T between the two partial shells. For example, a round chocolate body can be accommodated in the cavity and the appearance of the product can only be changed by the design of the planar element. For example, a different chocolate form does not need to be poured, depending on the season, but seasonal appearance can be controlled via the planar element. The planar element is formed by the beaded edge.

In particular, the location with the smallest width may also have 2 cm and / or the planar element may have a width of 2 cm substantially along the entire circumference of the package. The planar element has a certain width, so that the desired geometric shape of the package in its top view, which stands out from the geometric shape of the product, can be obtained. Further advantageous widths of the planar element to be understood as described above are 3 cm, 4 cm, 5 cm, 6 cm. These values can each form a lower or upper limit of a width range.

Material: cellophane; Raw material: wood; Basic material: cellulose.

Material: degradable polyester. Materials are referred to as biodegradable, if by microorganisms, or enzymes z. B. be mined in the ground. The degradation takes place mainly through oxidation and hydrolysis processes to the fission products water, carbon dioxide and biomass. In addition to various plastics made from renewable raw materials (bioplastics), the aforementioned definition also includes petroleum-based materials such as polyvinyl alcohols, polycaprolactones or certain copolyesters (eg PBAT: Ecoflex from BASF or Ecoworld from JinHui Zhaolong). However, not all bioplastics based on renewable raw materials are necessarily biodegradable (eg vulcanised rubber).

The term "biodegradable" is to be distinguished from polyolefin films (in particular PE) which are sometimes used in the packaging industry and which are declared as "oxo-biodegradable" or "oxodegradable." "Oxo-degradable" additives are usually metal ions (cobalt, manganese , Iron, zinc), which accelerate the oxidation and chain degradation in plastics, especially under heat, air and oxygen. The results of this chain degradation are very small, barely visible chain fragments that do not biodegrade (none of the additive manufacturers has so far been able to provide data), but move through our food chain. In the narrower sense (especially in the field of biomedicine) are referred to as biodegradable materials that are broken down in the body by macrophages, enzymes or hydrolysis within days to a few years. These include v.a. biogenic polymers such as collagen, fibrin or hyaluronic acid, but also polylactic acid (polylactide), polyglycolide and polycaprolactone. All of the aforementioned materials, which are broadly referred to as biodegradable, may find use. In particular, it is advantageous that these biodegradable materials are also biomaterials from renewable raw materials.

Examples of paper materials are chromo carton, fully bleached pulp, pulp paper, sugarcane paper, active polyvalent packaging based on environmental friendly fiber material with thermo-formable properties. In particular, thermoformable paper can be used. A thermoformable paper material is a material which, under the action of heat, can be transformed in a forming device, for example between two mold halves, such as a die, which is pressed into a cavity, as is known per se for thermoplastics. Such thermoformable paper materials have recently been used in some specialized fields. In particular, was used as a thermoformable paper material, a paper material of the company Billerudkorsnäs named "FIBER FORM ^®", which was produced in 2016. The paper thermoformable material may contain hydrophobic cellulose. These film materials preferably have the following thicknesses: 80 μm, 100 μm, 120 μm, 140 μm, 150 μm, 170 μm, 200 μm, 350 μm, 375 μm, 500 μm. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 80 to 500 μm is preferred. The paper materials are sometimes thicker than the plastic film materials.

According to one embodiment of the invention can be provided at a boundary line between the surface of the food and a boundary edge of the cutout in a region of the first or second sub-shell in which the first or second recess is provided, with the exception of the material thickness of the sub-shell no offset. The food can be inserted into the cavity between the dishes so that the surface curvature of the inner surface of the cavity at the edges of the cut corresponds in principle to the bending of the outer surface of the food. According to a development of the invention, a surface contour of the food in the cut-out can follow the contour of the packaging formed from the partial shells. It is advantageous that the outer surface of the food corresponds to an imaginary envelope surface that would be formed if the user would imagine the partial tray without the corresponding cutout. According to one embodiment of the invention, the cutout can be formed by a first partial cutout in the first partial shell and a second partial cutout on the second partial shell. As far as the food packaging is formed of more than two sub-shells, this can be limited per section of the more than two sub-shells. In particular, a partial cutout is provided on each of the subshells which delimits the cutout, on which, for example, no flange is provided.

According to one embodiment of the invention, the first and / or second partial shell with the exception of the partial cutout, which forms the cutout, and / or with the exception of the cutout can be completely limited by the flange. The subshells themselves are z. B. limited by a flange. In the area where the cutout of the packaging is formed, ie in particular the edges of the partial cutouts of the partial shells, have no flange. This is advantageous because in the neckline no means must be attached to which the sub-shells are coupled together.

According to one embodiment of the invention, the first and second subshells may each have a partial cutout, which has the same geometry, and / or that the two partial cutouts are connected to each other via the formed on the partial shells flanges and form the cutout. The partial cutouts are, for example, in order to generate the cutout via the flanges adjacent to the partial cutouts. Therefore, the cutout, in particular its boundary edge, be aligned transversely or perpendicular to the course of the flange.

According to one embodiment of the invention, the boundary edge of the cutout can have at least one region which extends transversely over a region of flanges of the partial shells flanged together.

According to one embodiment of the invention, the food may be a food hollow figure, which is provided in the region of the recess with a pattern. A pattern can be a print of the food or a pattern engraved in the hollow figure. For example, such a pattern may also be a different colored chocolate or a different colored material that is used as a contour line. These patterns on the food loaf figures may also be advantageous in combination with the other aspects of the invention.

According to one embodiment of the invention, a further packaging, in particular film packaging can be provided around the coupled-together part shells. The packaging with the cutout may preferably be received in a foil package, the z. B. is transparent and loosely surrounds the package described with the neckline. According to a development of the invention, the cutout can have a quarter-spherical-segment-shaped structure and / or a circular structure transversely to the main food axis. It looks visually particularly appealing when the cutout releases a three-dimensional curved area of the food, so that the food protrudes with a segment or a half out of the packaging. The various aspects described above can each also form inventions. The different aspects can also be combined in the packaging, which can also form an invention in itself. Each of the features described above may each be combined with a feature of the other group of aspects. Further advantageous developments of the invention will be explained with reference to the embodiments explained below in conjunction with the drawing. In this show:

Before the novel packaging or packaging part shell is presented in greater detail on the basis of the examples from FIGS. 6 to 19, the production of partial shells (FIGS. 1 a to c), the production of a food packaging from partial shells and beading are described by way of example with reference to FIGS the protruding edge portions (Figure 5a to e) explained in more detail.

FIG. 1 a shows a detail of a line of a device for producing a food packaging. This device can, for. B. be part of a packaging line, in which the corresponding steps from the provision of the packaging material to the finished packaged food product in individual successive stations are performed.

To provide the film, a device described in German Patent Application No. 10 2015 220 735.8 or a described method can be used.

After production of partial packaging shells, these may be in the manner as described in EP 2 366 631 A1 and / or in FIG. 1 of German Patent Application No. 10 2015 108 840.1 and the associated description and / or PCT application PCT / EP2016 / 051971 and / or German Patent Application No. 10 2015 101 417.3 is connected to each other to form a package.

The aforementioned disclosures of the various applications are hereby incorporated by reference into the disclosure of the present application.

The film web 1 is shown schematically in Figure 1 a on the left side. This is sucked in the example at the front end of a feeder 2 and spent by translation of this feeder 2 in a deformation device 3 (see Figure 1 b). The feed device 2, the deformation device 3 and a heating device 4 shown schematically in the example are controlled by a control device 5. In the example, the heating device 4 has two mutually opposite heating plates 12. It can also be used only a hot plate. Also every other heater, such as B. an infrared radiator is conceivable. In addition to the heating device, or alternatively to the heating device, a moistening device can also be provided. As far as used as a material for the partial shells paper or cardboard moistening before forming is particularly favorable because the material then deforms better. The combination of humidification and heating is also very suitable for forming paper. About this, the supplied film material can be heated. These are z. B. pressed against each other in the manner of a stamp and heat the recorded between them sheet material such. As paper, metal, plastic. However, such a heater is not necessary, for. B. if the material deforms well without heating. The deformation device 3 has an upper mold half 6 and a lower mold half 7. The upper mold half 6 has in the present case a regular arrangement of mold punches 8, which are positioned so that they are moved when moving the upper mold half 6 against the lower mold half 7 in corresponding mold cavities 9 of the lower mold half 7 in order to reshape the film material and thus to form depressions 10 in the film material (cf Figure 1 c). In Figure 1 a, a coordinate system is shown on the right side, which also applies to Figures 1 b and 1 c. Accordingly, the height direction in the following should correspond to the Z axis. The translation direction of the film web 1, in which it is brought into the deformation device 3 by means of the feed device 2, is referred to as X-axis. The direction perpendicular to the Z-axis and the X-axis, ie the direction in the paper plane in and out of the paper plane, is referred to as the Y-axis. Each of the upper and lower mold halves 6, 7 is substantially a rectangular mold half with regularly arranged mold punches 8 and mold cavities 9. When the film web 1 has been transferred into the deforming device 3, it is stored there. In the present case, the upper mold half 6 is pressed against the lower mold half 7, wherein in the film web 1 recesses 10 are formed. In the example described with reference to FIGS. 1 a to 1 c, the film web 1 is deposited in the deformation device 3 without first being divided into individual film sections. However, if a pre-cutting is provided before the deformation, this can be done by type and / or in such a device, as described in German Patent Application No. 10 2015 220 738.2, whose disclosure content in this regard by this reference in the present application is integrated. After, in the present example, the film web 1 has been deformed between the forming dies 8 and the mold cavities 9, so that the individual recesses 10 have been formed, this is finished by means of the cutting device 1 1 and brought into the form that a plurality of finished part shells , which form in the present half-shells is obtained. The method described with reference to FIGS. 1a to 1c is exemplary. For the production of the partial shells according to the invention, any other method can be used as long as the features described in the claims can be obtained. The partial shells 13, 13 'obtained by means of a forming or deep-drawing process have the depression 10 and a flange 14 delimiting the depression (compare FIG. Instead of a plurality of partial shells 13, 13 'being formed simultaneously as in the example, each partial shell 13, 13' can also be manufactured individually. The heating device shown in Figures 1 a to 1 c can also be omitted entirely. This is particularly advantageous if the material used for the partial shells can be formed without heating. The partial shells 13, 13 'produced by means of the device from FIGS. 1 a to 1 c are assembled to form the packaging in such a way that the corresponding flanges 14, 14' and the respective partial shell 13 are, for example, shown on the right-hand side in FIG , 13 'lie flat against one another and thus form an edge portion 15 projecting from the packaging. In the present case, this z. B. circumferentially formed as saturnartiger projecting edge portion 15.

In Figure 2 on the left side is a cross-sectional view of the finished cut sub-shell 13 and in Figure 2 in the middle a plan view of this sub-shell 13, wherein the recess 10 is arranged substantially centrally and is surrounded by the flange 14. About this flange 14 z. B., as shown in Figure 2 on the right side, a first sub-shell 13 with a second sub-shell 13 'connected after a chocolate charcoal figure or other food product in the wells 10 of the respective sub-shell 13, 13' formed cavity 16 has been inserted is. In the example in Figure 2, the packaged product is a chocolate egg. Therefore, the partial shells 13, 13 'formed as half-shells and form an egg-shaped structure. The sub-shells or packaging of the present invention may be of any configuration and is not limited to such egg-shaped configuration.

FIG. 3 shows, for example, a plan view of a partial shell 1 13, a nicholas-shaped packaging which can be used for a chocolate lemonade. Similar to the sub-shell 13, 13 'for the egg-shaped packaging of Figure 2, the sub-shell 1 13 a flange 1 14, which surrounds a formed in the sub-shell 1 13 recess 1 10. In the present case, the flange 1 14 surrounds the recess 1 10 fully.

FIG. 4 shows a cross-sectional view of the packaging on FIG. 3 along the line AA from FIG. The packaging is composed of two partial shells 1 13 ', 1 13. The corresponding flanges 1 14, 1 14 'of the respective sub-shell 1 13, 1 13' lie against each other and form a protruding edge portion 1 15. In the example, the flanges 1 14, 1 14 'sealingly connected to each other by a seal 124, so that the food received in the package is kept sealed in the package. The sealant layer may be obtained by an adhesive applied to the corresponding locations on the flanges. Alternatively or additionally, the material used for the part shells 1 13, 1 13 'also be coated on the inside with a thermoformable plastic, which melts after heating in the abutting flange portions and there forms the seal 124.

In FIG. 5f, starting from the example of FIG. 4, a situation is illustrated in which the protruding edge section 11 formed by opposing and abutting flanges 11 14, 14 'is crimped, so that a proximal edge section 11 1 and a distal edge are flared Edge portion 1 12 is formed, which are separated by a fold line 1 16.

As an example method, how such a flanging is produced, the method with the steps of Figures 5a to 5e is explained in more detail below.

In FIG. 5 a, the upper partial shell 203 and the lower partial shell 203 ', which receive a chocolate hollow figure 201 between them, are inserted into a mold cavity 209 provided in a lower mold half 208. The lower mold half 208 has a support region 210 on which a proximal edge section 21 1 of the two partial shells 203, 203 'rests in a planar manner. A distal edge portion 212 protrudes beyond the support portion 210 of the lower mold half 208 and projects laterally from the lower mold half 208. In the course of the method of FIG. 5a according to FIG. B, an upper mold half 213, which contains an upper mold cavity 214, is placed over the packaging formed by the two partial dishes 203, 203 ', so that the upper partial housing 203 comes to rest in the upper mold cavity 214 (see Figure 5b). The upper mold half 213 has a fixing surface 215, which defines the proximal edge portion 21 1 in cooperation with the support region 210 of the lower mold half 208. The proximal edge portion 21 1 is thus set between the fixing surface 215 and the support portion 210. For this purpose, the upper mold half 213 is pressed against the lower mold half 208, wherein the lower mold half 208 is so resilient or otherwise mechanically or kraftbeaufschlagt that they in the pressure exerted by the upper mold half 214 to this pressure, as shown in Figure 5b, light is pushed back. Here, the complete package of the two sub-shells 203, 203 'together with the protruding edge portion 205, pressed down in the vertical direction shown in the figures and moved against a fixed Umknickelement 216, so that the distal edge portion 212 against the proximal edge portion 21 first essentially kinked at 90 ° angle. Ultimately, however, may also be the upper and lower mold halves 208, 214 formed fixed and the Umknickelement 216 may be formed as a height-displaceable element. Ultimately, one should Displacement of the Umknickelements 216 are guaranteed in relation to the specified flange. In order to ensure a simple buckling, the buckling element 216 has a rounded surface 217 on a region facing a fold line formed between the proximal edge section 21 1 and the distal edge section 212. It is at least during the kinking one of the two surfaces, the fixing surface 215 or the support portion 210 or both of these surfaces and / or additional areas of the surface of the Umknickelements 216, in particular areas of the rounded surface 217, are heated, so that the two layers in the edge region due to the heat effect can be easily deformed and folded over. Even while setting at this stage, z. B. be prepared by heating a seal. After the distal edge portion 212 has been bent at an angle of approximately 90 ° in the method step shown in FIG. 5b, the final folding or flanging takes place in the steps illustrated in FIGS. 5c to 5e. After the upper mold half 213 has been raised again in the vertical direction in the case of the folding shown in FIG. 5b, the lower mold half 208 is again moved into the starting position shown in FIG. 5a. Preferably, this occurs due to the resilient mounting of the lower mold half 208 when the upper mold half 213 is retracted. The Umknickelement 216 is positioned in this initial state or crimping state of the forming half 208, that is below the support region 210 of the lower mold half 208. A multi-part second upper mold half 218, which may be a different mold half than the upper mold half 213, has, seen in the radial direction of the packaging or projecting edge portion 205, on its outer region a longitudinally spring-mounted forming die 219 (see FIG. , This has an oblique Umschlagoberflächenbereich 220, which is positioned with respect to the distal edge portion 212 such that the Umlegeoberflächenbereich 220 as far as the movable forming punch 219 is pressed in a horizontal downward direction against the raised distal flange 212, the kinked distal edge portion 212 at least slightly angled inwardly out of the 90 ° angle (see Figures 5c, 5d). As a result, an edge-side end of the distal edge portion 212 enters an area of a fixing surface 221 of the multi-part second upper mold half 218. Thus, the forming die 219 in the embodiment is formed as part of the second upper mold half 218 and suspended by a spring. However, other embodiments that allow the described kinematics are also possible. The radial orientation of the locating surface 221 as seen in the cross-sectional direction in FIG. 5c is preferably smaller than the radial extent of the bearing portion 210 of the lower mold half 208. The radial longitudinal extent of the locating surface 221 together with the inclined flipping surface area 220 is slightly greater than that Extension of the support portion 210 of the lower mold half 208, or substantially corresponds to the radial extent of the support portion 208. In the step shown in Figure 5d, the distal edge portion 212 by means of the movable forming punch 219 is bent inwards and subsequently with the fixing surface 221st of the molded body 222 of the upper multi-part second mold half 218 to be finally folded or folded. Even during the last step can z. B. take place by heating the fixing surface 221 of the molding 222, a seal. While the upper multi-part mold half 218 is being shut down, a counter force against the weight force of the die 219 is exerted on the spring-free die 219 so that it relatively shifts in relation to the die 222 of the upper multi-part mold half 218. Such a relative displacement can also be achieved instead of the resilient suspension by a motor position or other kinematics. In order to achieve a corresponding counterforce, the lower mold half 208 z. B. during the process steps c, d and e set. For example, with the step illustrated in FIG. 5, the protruding edge portion 205 formed by two opposing flanges is crimped on itself. This process is described purely by way of example.

As far as a flange is provided at all for connecting the partial shells according to the invention, this will be mentioned again below. However, such a flanging is not essential and can be omitted entirely.

In the case of the packaging according to the present invention, it is advantageous for the food product to rest on the inner walls of the cavity in a contour-shaping manner, in particular over the whole area, which is formed by depressions of the partial shell. However, other embodiments are possible. The partial shells are z. B. made of a sheet of material or of a film strip of a roll and have a certain stability after their transformation, so that the depression with the surrounding flange is formed.

A contour-imaging system can be a full-surface system that depicts the contour of the food. However, such a plant does not exclude narrowly defined sections in which the packaging tray is a small distance from the food surface. Such a distance between the packaging inner wall and the food surface may be present, for example, in areas in which different geometries of the food meet, for example in the face of a food designed as a figure in the area where eyes and nose meet and / or in the area of the transition between hand and arm , Such a distance may also occur in portions of the food surface with small radii or high bending. The distances can be up to 1 μηη, 50 μηη, 1 mm, 5 mm, or even up to 10 mm. The aforementioned distances can each form upper and lower limits of the distance range. Large distances of 5mm or even up to 10mm may be provided, for example, to avoid tearing the paper elsewhere. The individual aspects of the partial shells or packaging according to the invention with reference to example groups will be explained below by way of example.

Example Group 1

In FIGS. 6 to 9, in particular, examples are shown in which the flange 307, 308 has a first region of a first material and a second region of a second material, which is different from the first material. The example group 1 illustrates in particular the third aspect of the invention.

6a to 6e show a food package 301 in different views, wherein FIG. 6a shows a frontal view, FIG. 6b shows a rear view, FIG. 6c shows a side view, FIG. 6d shows a cross sectional view along the line DD in FIG. 6b, and FIG. 6e shows a cross sectional view along the line EE in FIG Figure 6b shows.

In this food packaging, a food may be packaged (see FIG. The food package 301 has a first sub-tray 303 (see Fig. 6a) and a second sub-tray 304 (see Fig. 6b). The first part-shell 303 has a first recess 305 and a first flange 307 delimiting the first recess 305. The second partial shell 304 has a second depression 306 and a second depression 306 delimiting the second depression 306. The flanges 307, 308 rest on one another when the partial shells 303, 304 are folded (see FIG. 6c) and form a protruding edge section 309.

In FIGS. 6c, 6d and 6e, a gap is shown between the opposing flanges 307, 308. This is owed in the present case only for clarity. The two flanges 307, 308 are z. B. connected to each other, so that the first sub-shell 303 is coupled to the second sub-shell 304 via these flanges 307, 308. In the present case, each partial shell 303, 304 is provided with a flange surrounding it in its entirety, so that the respective depression 305, 306 is completely bounded by this flange 307, 308. Such a flange may also only partially limit the respective recess 305, 306 and thus be formed only on partial areas of the outer circumference of the respective partial shell 303, 304. The flanges are formed areal and between the respective flanges 307, 308 and the recess 305, 306 is a bend line 310, 31 1 (310 first bend line, 31 1, second crease line) is provided. One The proximal flange portion 312 is connected to the respective recess 305, 306 via the bending line 310, 31 1, and a distal flange portion 313 delimits the respective partial shell 303, 304 on its outer circumference. Of the first and the second recess 305, 306, a cavity 314 is formed in the package 301, in which the food 302 is received. In the present case (see FIG. 7), the food 302 is accommodated in the cavity 314 in such a way that it rests on the inner walls of the cavity 314 in a contour-shaping manner, in particular over the whole area. The food 302 can also be loosely received in the cavity 314, wherein the corresponding sub-shells 303, 304 have a certain stability, so that the cavity 314 also has areas which are then not filled by the food 302.

In the examples of FIGS. 6 to 8, the food 302 is a chocolate hollow figure, in particular a chocolate Santa Claus. The chocolate figure does not have to be hollow, but can also be massively filled with liquid or pasty substances. In addition to the Nikolausform can also any other shape, such. Eg egg shape, Easter Bunny shape, frog shape or bear form may be provided.

In the present case, the protruding edge portion 309 is not crimped and surrounds the food packaging in the manner of a saturn-shaped ring. The protruding edge portion 309 surrounds the food packaging in such a way that it forms a parting plane T (see FIG. 6c) between the two subshells 303, 304 (see the broken line in FIG. In the packaging shown by way of example, two partial shells, each forming a half-shell, are provided. The packaging may also be formed from more than two partial shells. Each shell itself forms a unitary integral element. In the present case, the first partial shell 303 is made of two different materials. A first material 315 is indicated by the hatching. A second material 316, which is different from the first material 315, is not shown hatched.

8d, a third material 317 (see carafe hatching) is provided for the corresponding subshell 303, 304, so that the subshell 303, 304 of FIG. 8 is constructed of three different materials.

As materials metal, paper or plastic can be used. The term "metal, paper or plastic" is based on the corresponding surface layer, ie the different materials are at least different surface materials of the corresponding sub-shells.A multilayer material can also be used, for example a paper sheet laminated with plastic film Partial shells also have a different material if they have superficially different materials, ie it can be, for example, a segment the partial shell having a surface of paper and an inner surface of a plastic film laminated with the paper and for another segment the same multilayer material are used, in which case the plastic film on the outside and the paper is provided on the inside. Under paper is to be understood also cardboard.

Examples of plastic materials are thermoformable plastic film materials such as polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS), polyester. These film materials preferably have the following strengths: 80 μm, 100 μm, 120 μm, 140 μm, 150 μm, 170 μm, 200 μm, 350 μm, 375 μm, 500 μm, 520 μm, 700 μm. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 80 to 375 μm is preferred.

Material: thermoplastic starch or starch blends; Raw material: potato,

Wheat, corn; Basic material: starch.

Material: cellophane; Raw material: wood; Basic material: cellulose.

Examples of paper materials are chromo carton, fully bleached pulp, pulp paper, sugarcane paper, thermo-formable fiber material (active polyvalent packaging based on environmentally friendly fibrous material). In particular, thermoformable paper can be used. A thermoformable paper material is a material which, under the action of heat, can be transformed in a forming device, for example between two mold halves, such as a stamp which is pressed into a cavity, as is known per se for thermoplastics. Such thermoformable paper materials have recently been used in some specialized fields. In particular, was used as a thermoformable paper material, a paper material of the company Billerudkorsnäs named "FIBER FORM ^®", which was produced in 2016. The paper thermoformable material may contain hydrophobic cellulose. These film materials preferably have the following thicknesses: 80 μm, 100 μm, 120 μm, 140 μm, 150 μm, 170 μm, 200 μm, 350 μm, 375 μm, 500 μm. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 80 to 500 μm is preferred. The paper materials are sometimes thicker than the plastic film materials.

Different multilayer materials can also be used. As far as the invention is geared to different materials, in each case at least surface areas / segments of different materials should be provided.

Since the two subshells 303, 304 are coupled to one another via the flanges 307, 308, at least one uniform flange made of the same material has hitherto been used in the prior art and two such flanges are connected to one another.

The inventors of the present invention have surprisingly found, for the first time, that flanges with regions made of different materials can be connected to one another in such a way that the partial shells hold together tightly enough to accommodate a corresponding foodstuff.

Therefore, it is possible to provide a flange having a first region 318 of the first material 315 and a second region 319 of the second material 316. Such flanges on partial shells of different materials can be securely coupled together.

It is advantageous that the first flange region 318 and the second flange region 319 are arranged adjacent to one another via a joint line 320. At the butting line 320, the different materials 315, 316 abut each other. The piling line 320 may also be generated by overlapping different sheets of material, or may arise from the fact that in a multilayer material, the surface in the second area 319 has been removed and then the underlying layer is revealed. Any combination of paper, foil, metal, and multilayer material, as previously described, is contemplated.

In the example in Figure 6a, the score line 320 extends perpendicularly across a transition formed by the crease line 310 between the first flange 307 and the first recess 305 to the distal flange portion 313. Any oblique configuration such that the dash line extends across the flange 307 , is advantageous.

In the example of FIGS. 6a to 6e, only the first subshell is constructed from two materials, wherein the second subshell is constructed from a uniform material. This material may be a third material that is different from the first and second materials of the first sub-shell 303, but it may also be the first or second material.

In the example in Figure 7, the second material 316 is clear plastic material so that one can see the head portion of the Santa Claus. This ensures an attractive appearance, especially if the chocolate hollow figure in addition to dark chocolate also different colored chocolate, with the z. B. the contours of the figure are drawn.

FIGS. 8a to 8d show different configurations of the first and / or second partial shell 303, 304. That is, the partial shells shown in FIGS. 8a to 8d can be front, rear or another side of the food package 301. In FIG. 8a, the first region 318 has a round structure with a corrugated joint line 320. The corrugated joint line 320 does not run rectilinearly in the area of the flange.

FIG. 8b shows a situation in which the joint line extends across the flange. The situations illustrated in FIGS. 6 and 8b show a joint line formed with respect to the flange by a first joint line 321 and a second joint line 322. The first joint line 321 and the second joint line 322 are connected to each other via the third joint line 323 in the region of the depression 305/306 and form the only continuous joint line. The first joint line 321 and the second joint line 322 are provided in different flange regions and are arranged in alignment with each other on different sides of the corresponding sub-shell in FIGS. 6a, 8b and 8d. In the example shown in FIG. 8c, the flange 307, 308 is not formed completely circumferentially about the recess 305, 306, but only in a lower region of the package forming the nicholas-like partial shell. In this case, only a single joint 320 is provided on the flange or the joint line intersects the flange only Times. In the example of FIG. 6c, two different partial shells with different material distribution will be used. It is always possible to use the same shells with the same material distribution. Partial shells with the same material distribution do not mean that they also have the same geometry (front or rear side of the chocolate hollow figure), but only the course of the joint line is the same, so that composite partial shells, for example, have a peripherally formed joint line.

Example Group 2

A group of examples illustrating the fourth aspect of the invention is shown in Figs. According to the fourth aspect of the invention, the partial shell 403, 404 is formed by deep drawing. The deep-drawn material is already supplied in a segment-like configuration for forming, so that the partial shell has at least two surface segments (first region 418, second region 419) made of different materials. For the embodiment of the partial shells or packaging applies to example group 1 previously said accordingly. Therefore, only the most important aspects are summarized below. Present in the second example group corresponding features from the first example group with the same reference numerals, but instead of 300 numbers with 400 numbers provided, with z. B. the first and second sub-shell with the reference numerals 403 and 404, flanges with the reference numeral 407, 408 and the protruding edge with reference numeral 409 are provided.

In the food packaging, a food can be packed. The food package 401 has a first partial shell 403 and a second partial shell 404. The first part-shell 403 has a first recess 405 and a first flange 407 delimiting the first recess 405. The second partial shell 404 has a second depression 606 and a second depression 408 delimiting the second depression 406. The flanges 407, 408 are in collapsed partial shells 403, 404 to each other and form a protruding edge portion 409. The two flanges 407, 408 z. B., so that the first sub-shell 403 is coupled to the second sub-shell 404 via these flanges 407, 408. In the present case, each partial shell 403, 404 is provided with a flange surrounding it in its entirety, so that the respective depression 405, 406 is completely delimited by this flange 407, 408. Such a flange may also only partially limit the respective recess 405, 406 and thus be formed only on partial areas of the outer circumference of the respective partial shell 403, 404. The flanges are formed in the present area and between the respective flanges 407, 408 and the recess 405, 406 a bend line 410, 41 1 is provided. A proximal flange portion 412 is connected via the bending line 310, 31 1 with the respective recess 405, 406 and a distal flange portion 413 bounds the respective partial shell 403, 404 on its outer periphery. Of the first and the second recess 405, 406, a cavity is formed in the package 401, in which the food is received. As shown in FIG. 7, the food can be received in the cavity in such a way that it rests against the inner walls of the cavity 414, in particular over its full area, in the contour of this contour. The food 402 can also be accommodated loosely in the cavity 414, wherein the corresponding subshells 403, 404 have a certain stability, so that the cavity 414 also has areas which are then not filled by the food 402.

Likewise, as in the examples of FIGS. 6 to 8, the food 402 may be a chocolate hollow figure, in particular a chocolate Santa Claus. The chocolate figure does not have to be hollow, but can also be massively filled with liquid or pasty substances. In addition to the Nikolausform can also any other shape, such. Eg egg shape, Easter bunny form, frog or bear form may be provided.

In the present case, the protruding edge portion 409 is not crimped and surrounds the food packaging in the manner of a saturn-shaped ring, which follows the contour of the product. The projecting edge portion 409 can also surround the food package in this example group in such a way that it forms a parting plane T (see FIG. 6c) between the two part-shells 403, 404 (see dashed line in FIG. In the packaging shown by way of example, two partial shells, each forming a half-shell, are provided. The packaging may also be formed from more than two partial shells. Each shell itself forms a unitary integral element. In the present case, the first partial shell 403 is made of two different materials. A first material 415 is indicated by the hatching. A second material 416, which is different from the first material 315, is not shown hatched.

As materials metal, paper or plastic can be used. The term "metal, paper or plastic" is based on the corresponding surface layer, ie the different materials are at least different surface materials of the corresponding sub-shells.A multilayer material can also be used, for example a paper sheet laminated with plastic film Partial shells also have a different material if they have superficially different materials, ie, for example, one segment of the partial shell may have one surface of paper and one inner surface of a plastic film laminated with the paper and the same for another segment Multi-layer material can be used, in which case the plastic film is provided on the outside and the paper on the inside. Under paper is to be understood also cardboard.

Material: cellophane; Raw material: wood; Basic material: cellulose.

Material: degradable polyester.

In addition to various plastics made from renewable raw materials (bioplastics), petroleum-based materials such as polyvinyl alcohols also fall under the aforementioned definition. Polycaprolactones or certain copolyesters (eg PBAT: Ecoflex from BASF or Ecoworld from JinHui Zhaolong). However, not all bioplastics based on renewable raw materials are necessarily biodegradable (eg vulcanised rubber). The term "biodegradable" is to be distinguished from polyolefin films (in particular PE) which are sometimes used in the packaging industry and which are declared as "oxo-biodegradable" or "oxodegradable.""Oxo-degradable" additives are usually metal ions (cobalt, manganese , Iron, zinc), which accelerate the oxidation and chain degradation in plastics, especially under heat, air and oxygen. The results of this chain degradation are very small, barely visible chain fragments that do not biodegrade (none of the additive manufacturers has so far been able to provide data), but move through our food chain.

Examples of paper materials are chromo carton, fully bleached pulp, pulp paper, sugarcane paper, thermo-formable fiber material (active polyvalent packaging based on environmentally friendly fibrous material). In particular, thermoformable paper can be used. A thermoformable paper material is a material that can be thermally deformed in a forming device, eg, between two mold halves, such as a stamp that is pressed into a cavity, as is known per se for thermoplastics is. Such thermoformable paper materials have recently been used in some specialized fields. In particular, was used as a thermoformable paper material, a paper material of the company Billerudkorsnäs named "FIBER FORM ^®", which was produced in 2016. The paper thermoformable material may contain hydrophobic cellulose.

These film materials preferably have the following thicknesses: 80 μm, 100 μm, 120 μm, 140 μm, 150 μm, 170 μm, 200 μm, 350 μm, 375 μm, 500 μm. The above-mentioned strengths can in each case be lower or upper limits of a preferred one in each case Strength range form. In particular, a range of 80 to 500 μm is preferred. The paper materials are sometimes thicker than the plastic film materials.

FIGS. 9a to 9d show different examples of partial shells with regions of different materials. FIGS. 9a to 9d each show a partial shell 403, 404, which can form the first and / or the second partial shell. It is not necessary that both partial shells are formed with the same material distribution. It may also be one of the partial shells made of a uniform material and only one of the partial shells of the different materials. Figures 10a to 10d show various configurations of sheets which are e.g. B. in the method of Figures 1 a to 1 c of the forming device can be supplied.

FIGS. 10a to 10d schematically show a material sheet 430, 431, 432, 433 which is fed to the forming device, for example, in the manner illustrated in FIGS. 1a to 1c. The material sheet has a segment-like surface with a first segment 441 and a second segment 442. How this segment-like surface can be constructed is shown schematically in the circled sections of a cross-sectional view in FIGS. 10a and 10b.

In the example in FIG. 10a, the first segments 441 are replaced by a first one

Material portion 443 and formed the second segments 442 by a second material portion 444 of a different material from the first material portion. The second material sections 444 are each connected to the longitudinal edges of the first material sections 443 at their longitudinal edges at the rear. Thus, as shown in Figure 10a, a strip-shaped structure with a plurality of surface strips of the first material 415 and a plurality of surface strips of the second material 316. As far as in this context on first and second or different materials is turned off, is also turned off on the surface.

As described above for example group 1, a multilayer material can also be used in which the individual segments are then fastened twisted together. In the example in FIG. 10b, the segmental configuration of the material sheet is achieved by providing a surface layer 445 of the second material 416 with cutouts or window openings 446 and laminating another layer 447 underneath with the surface layer 445. In the window openings 446, the surface of the further layer 447 can be seen. FIG. 10c shows a combination of a strip-shaped segment-shaped configuration and a window-like segment-shaped configuration. The material sheet 432 may have different regions with different segmental structures.

The different regions with the segment-like structures can be produced from laminated foils or from material sections connected to one another at their longitudinal edges, as in the different types described with reference to FIGS. 10a or 10b.

In FIG. 10d, circular window openings 446 are formed. This film material is processed, for example, in the apparatus shown in FIGS. 1a to 1c, and the partial shells shown in FIGS. 9a to 9d are produced. The segmental design of the material sheets is matched to the desired segmental configuration of the partial shells. By feeding the finished material with different surfaces, the corresponding sub-shells can be produced quickly in a simple manner. The partial shells can be coupled to one another via their flanges, for example by crimping the projecting edge sections formed by the opposing flanges. But such a flanging is not necessary.

Example Group 3 A group of examples illustrating the seventh aspect of the invention is shown in FIGS. 11 and 12.

According to the seventh aspect of the invention, the food package 501 is formed so that a cutout 550 is formed and the food 502 protrudes from the package through the cutout 550 (see Fig. 12).

For the embodiment of the partial shells or packaging applies to example group 1 and example group 2 previously said accordingly. Therefore, only the most important aspects are summarized below. Present in the third example group corresponding features from the first example group or from the second example group with the same reference numerals, but with 500 numbers provided, with z. B. the first and second sub-shell with the reference numerals 503 and 504, flanges with the reference numerals 507, 508 and the protruding edge with reference numeral 509 are provided.

In the food packaging, a food can be packed. The food packaging 501 has a first partial shell 503 and a second partial shell 504. The first subshell 503 has a first recess 505 and a first flange 507 delimiting the first recess 505. The second subshell 504 has a second recess 506 and a second flange 508 delimiting the second recess 506. The flanges 507, 508 are in collapsed partial shells 503, 504 to each other and form a protruding edge portion 509. The two flanges 507, 508 z. B., so that the first sub-shell 403 is coupled to the second sub-shell 504 via these flanges 507, 508. In the present case, each partial shell 503, 504 is provided with a flange surrounding it in its entirety, so that the respective depression 505, 506 is completely delimited by this flange 507, 508. Such a flange may also only partially limit the respective recess 505, 506 and thus be formed only on partial areas of the outer circumference of the respective partial shell 503, 504. The flanges are formed in the present area and between the respective flanges 507, 508 and the recess 505, 506, a bending line 510, 51 1 is provided. A proximal flange portion 512 is connected to the respective recess 505, 506 via the bending line 510, 51 1, and a distal flange portion 513 delimits the respective partial shell 503, 504 on its outer circumference. Of the first and the second recess 505, 506, a cavity is formed in the package 501, in which the food is received. As shown in FIG. 7, the food can be received in the cavity in such a way that it rests against the inner walls of the cavity 514, in particular contouring the entire surface. Likewise, as in the examples of FIGS. 6 to 8, the food 502 may be a chocolate hollow figure, in particular a chocolate Santa Claus. The chocolate figure does not have to be hollow, but can also be massively filled with liquid or pasty substances. In addition to the Nikolausform can also any other shape, such. Eg egg shape, Easter Bunny shape, frog shape or bear form may be provided.

In the present case, the protruding edge portion 509 is not crimped and surrounds the food packaging in the manner of a saturn-shaped ring. However, a flanging is very advantageous in this third example group, since the cutout, as described later, then passes smoothly into the packaging. In the packaging shown by way of example two partial shells are provided. The packaging may also be formed from more than two partial shells. Each shell itself forms a unitary integral element.

As materials metal, paper or plastic can be used. The term "metal, paper or plastic" is based on the corresponding surface layer, ie, if different materials are used, at least different surface materials of the corresponding sub-shells are used.A multilayer material, for example a laminate laminated with plastic film, can also be used The sub-shells have a different material even if they have superficially different materials, ie, for example, one segment of the sub-shell may have one surface of paper and one inner surface of a plastic film laminated with the paper and another segment in this case, the plastic film is provided on the outside and the paper on the inside, and paper is also meant to be cardboard ialien, such as polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS), polyester. These film materials preferably have the following thicknesses: 80 μm, 100 μm, 120 μm, 140 m, 150 m, 170 m, 200 μm, 350 μm, 375 μm, 500 μm, 520 μm, 700 μm. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 80 to 375 μm is preferred.

So far, packaging for food, as far as they were made of plastic, from conventional plastics, especially non-biodegradable thermoplastics such as polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS) produced.

The recovery rate of such conventional plastic materials is often insufficient. To address this problem, new compostable materials with similar barrier properties can be used. Examples of such biodegradable plastic materials, the raw material of which they are made, and their base are shown below: Material: Polyhydroxyalkanoate, e.g. Polyhydroxybutylate (PHB), polyhydroxyvinylate (PHV); Raw material: starch, sugar; Basic material: starch, sugar.

Material: thermoplastic starch or starch blends; Raw material: potato,

Wheat, corn; Basic material: starch.

Material: cellophane; Raw material: wood; Basic material: cellulose.

Material: degradable polyester.

The term "biodegradable" is to be distinguished from polyolefin films (in particular PE) which are sometimes used in the packaging industry and which are declared as "oxo-biodegradable" or "oxodegradable.""Oxo-degradable" additives are usually metal ions (cobalt, manganese , Iron, zinc), which accelerate oxidation and chain degradation in plastics, especially under heat, air and oxygen. The results of this chain degradation are very small, barely visible chain fragments that do not biodegrade (none of the additive manufacturers has so far been able to provide data), but move through our food chain. In the narrower sense (especially in the field of biomedicine) are referred to as biodegradable materials that are degraded in the body by macrophages, enzymes or hydrolysis within days to a few years. These include, in particular, biogenic polymers such as collagen, fibrin or hyaluronic acid, but also polylactic acid (polylactide), polyglycolide and polycaprolactone.

All of the aforementioned materials, which are broadly referred to as biodegradable, may find use. In particular, it is advantageous that these biodegradable materials are biomaterials from renewable raw materials.

Examples of paper materials are chromo carton, fully bleached pulp, pulp paper, sugarcane paper, thermo-formable fiber material (active polyvalent packaging based on environmentally friendly fibrous material). In particular, thermoformable paper can be used. A thermoformable paper material is a material which, under the action of heat in a forming device, for example between two mold halves, such as. As a stamp that is pressed into a cavity can be reshaped, as it is known per se for thermoplastics. Such thermoformable paper materials have recently been used in some specialized fields. In particular, as a thermoformable paper material, a paper material of the company Billerudkorsnäs named "FIBER FORM ^®", which was produced in 2016, used the thermoformable paper material may contain hydrophobic cellulose This film materials preferably have the following strengths:.. Μηη 80, 100 μηη, 120 μηη , 140 μηη, 150 μηη, 170 μηη, 200 μηη, 350 μηη, 375 μηη, 500 μηη The above-mentioned starches can in each case in each case form lower or upper limits of a preferred range of strengths, in particular a range from 80 to 500 The paper materials are sometimes thicker than the plastic film materials Examples of metal foil materials are aluminum foil, stainless steel foil, copper foil.

In the example group 3, the food package 501 is formed so that a cutout 550 is formed and the food 502 through the cutout 550 from the Packaging looks out (see Figure 12). The corresponding subshells 503, 504 have such stability that such a cutout can be left free.

FIGS. 11a to 11d show different views of the food packaging 501 from two partial shells, wherein FIG. 11a shows a frontal view, FIG. 11b shows a rear view, FIG. 11c shows a side view from a first side, and FIG Side view of a first side shows, wherein in the example of Figure 1 1 no food is inserted into the packaging,

FIGS. 11a to 11d show a situation in which no food is received in the food package 501. The food packaging 501 has the cutout 550, wherein in the present case the cutout 550 is formed from a first partial cutout 551 in the first partial bowl 503 and a second partial cutout 552 in the partial bowl 504. The two partial shells 503, 504 are coupled to one another via their flanges 507, 508 such that approximately one quarter of the packaging has the cutout 550. The transition between the first partial cutout 551 and the second partial cutout 552 runs transversely, in this case even vertically above the region of the protruding edge portion 509. In the present case, it is advantageous to apply the protruding edge portion 509 to the outer circumferential surface of the food packaging 501, and / or to crimp, for example, with the method as described in Figures 5a to 5e. If the package has an applied and / or beaded edge, the open-cut look is particularly beautiful. A beaded edge corresponds to a folded-back edge. In any case, an applied edge is kinked at the bend line 51 1, 510 and applied to the outer surface of the packaging. Even a beaded border can be created additionally.

In the exemplary embodiment in FIG. 12, the first subshell and the second subshell 503, 504 contour-image, in particular over the entire surface of the food 502 (chocolate Santa Claus) and in particular in the region of the respective first recess 505 and second recess 506 results with the exception of Material thickness of the corresponding sub-shell 503, 504 at the transition between the sub-shell surface and section no significant offset between the surface of the food and the surface of the sub-shells. In the present example, the contour of the chocolate figure essentially follows the contour predetermined by the partial shells, also in the region of the cutout. It is not necessarily the case that a section is formed by the interaction of the individual partial shells 503, 504. Such a cutout can also be provided in one of the partial shells. In a region of the first partial cutout 551 or of the second partial cutout 552, the respective partial shell 503, 504 has no flange, otherwise In this example, too, the first or second flange 507, 508 runs completely around the packaging. In order to better protect the so packaged food, it is advantageous to the packaging shown in Figure 12 in a further, z. B. transparent packaging, eg. In a cellophane film or blister.

There is no restriction for the individual materials of the partial shell. However, the configuration with the cutout can also be combined in conjunction with all elements mentioned with reference to example groups 1 and 2, respectively.

Example Group 4 A second aspect of the invention will be described with reference to Figs. 13a to 13d.

According to the second aspect of the invention, a window 660 of a first material 615 is provided in the partial shell 603, which is different from a second material 616, which forms at least one outer surface of the partial shell 603.

For the embodiment of the partial shells or the packaging that applies to example group 1 to 3 previously said accordingly. Therefore, only the most important aspects are summarized below. In the fourth example group, corresponding features from the first to third example groups are provided with the same reference numerals, but with 600 numbers, wherein z. B. the first and second sub-shell with the reference numerals 603 and 604, flanges with the reference numerals 607, 608 and the protruding edge with reference numeral 609 are provided.

In the food packaging, a food can be packed. The food package 601 has a first partial shell 603 and a second partial shell 604. The first partial shell 603 has a first depression 605 and a first flange 607 delimiting the first depression 605. The second partial shell 604 has a second depression 606 and a second flange 608 delimiting the second depression 606. The flanges 607, 608 are in collapsed partial shells 603, 604 to each other and form a protruding edge portion 609. The two flanges 607, 608 can z. B., so that the first sub-shell 603 is coupled to the second sub-shell 604 via these flanges 607, 608. In the present case, each partial shell 603, 604 is provided with a flange surrounding it in its entirety, so that the respective depression 605, 606 is completely bounded by this flange 607, 608. Such a flange may also only partially limit the respective recess 605, 606 and thus be formed only on partial areas of the outer circumference of the respective partial shell 603, 604. The flanges are presently formed flat and between the respective flanges 607, 608 and the recess 605, 606 a bend line 610, 61 1 is provided. A proximal flange portion 612 is connected to the respective recess 605, 606 via the bending line 610, 61 1, and a distal flange portion 613 delimits the respective partial shell 603, 604 on its outer circumference. Of the first and the second recess 605, 606, a cavity 614 is formed in the package 501, in which the food is received. The food can, as shown in relation to example group 1 in FIG. 7, be accommodated in the cavity in such a way that it rests against the inner walls of the cavity 614, in particular contouring the entire surface.

It may also, as in the examples of Figures 6 to 8, the food 602 is a chocolate char, especially a chocolate Santa Claus. The chocolate figure does not have to be hollow, but can also be massively filled with liquid or pasty substances. In addition to the Nikolausform can also any other shape, such. Eg egg shape, Easter Bunny shape, frog shape or bear form may be provided.

In the present case, the protruding edge portion 609 is not crimped and surrounds the food packaging in the manner of a saturn-shaped ring. But a flanging can be provided alternatively.

In the packaging shown by way of example two partial shells are provided. The packaging may also be formed from more than two partial shells. Each shell itself forms a unitary integral element. As materials metal, paper or plastic can be used. The term "metal, paper or plastic" is based on the corresponding surface layer, ie, if different materials are used, at least different surface materials of the corresponding sub-shells are used.A multilayer material, for example a laminate laminated with plastic film, can also be used The sub-shells have a different material even if they have superficially different materials, ie, for example, one segment of the sub-shell may have one surface of paper and one inner surface of a plastic film laminated with the paper and another segment the same multilayer material is used, in which case the plastic film is provided on the outside and the paper on the inside, and paper is also understood to mean cardboard.

Examples of plastic materials are thermoformable plastic film materials such as polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS), polyester. These film materials preferably have the following thicknesses: 80 μm, 100 μm, 120 μm, 140 μm, 150 μηι, 170 μηι, 200 μηι, 350 μηι, 375 μηι, 500 μηι, 520 μηι, 700 μηι. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 80 to 375 μm is preferred. So far, packaging for food, as far as they were made of plastic, made of conventional plastics, especially non-biodegradable thermoplastics such as polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS). The recovery rate of such conventional plastic materials is often insufficient. To address this problem, new compostable materials with similar barrier properties can be used. Examples of such biodegradable plastic materials, the raw materials from which they are made, and their raw material are shown below:

Material: polyhydroxyalkanoate, e.g. Polyhydroxybutylate (PHB), polyhydroxyvinylate (PHV);

Raw material: starch, sugar; Basic material: starch, sugar.

Material: thermoplastic starch or starch blends; Raw material: potato,

Wheat, corn; Basic material: starch.

Material: cellophane; Raw material: wood; Basic material: cellulose.

Material: degradable polyester.

The term "biodegradable" is to be distinguished from polyolefin films (especially PE) sometimes used in the packaging industry, which are classified as "oxo-biodegradable" or "oxo-biodegradable". "Oxo-degradable" additives are mostly metal ions (cobalt, manganese, iron, zinc) which accelerate oxidation and chain degradation in plastics, especially under heat, air and oxygen. The results of this chain degradation are very small, barely visible chain fragments that do not biodegrade (none of the additive manufacturers has so far been able to provide data), but move through our food chain.

All of the aforementioned materials, which are broadly referred to as biodegradable, may find use. In particular, it is advantageous that these biodegradable materials are also biomaterials from renewable raw materials. Examples of paper materials are chromo carton, fully bleached pulp, pulp paper, sugarcane paper, thermo-formable fiber material (active polyvalent packaging based on environmentally friendly fibrous material). In particular, thermoformable paper can be used. A thermoformable paper material is a material which, under the action of heat in a forming device, for example between two mold halves, such as. As a stamp that is pressed into a cavity can be reshaped, as it is known per se for thermoplastics. Such thermoformable paper materials have recently been used in some specialized fields. In particular, was used as a thermoformable paper material, a paper material of the company Billerudkorsnäs named "FIBER FORM ^®", which was produced in 2016. The paper thermoformable material may contain hydrophobic cellulose.

These film materials preferably have the following thicknesses: 12 μm, 15 μm, 18 μm, 20 μm, 25 μm, 30 μm, 50 μm, 70 μm, 100 μm, 200 μm. The above-mentioned strengths can in each case be lower or upper limits of a preferred one in each case Strength range form. In particular, a range of 12 to 200 μm is preferred. The metal foil materials are sometimes preferably thinner than the plastic film materials.

Figures 13a to 13d show various examples of partial shells having a window of a different material from the partial shell surface. The double reference numerals in the figures are due to the fact that the partial shell shown, the first and second partial shell may be.

In the partial shell 603, 604, a window 660 made of a first material 615 is provided, which is different from a second material 616, which forms at least one outer surface of the partial shell 603.

The window can also be made in the manner described for example group 2.

As a window, a material is usually used, which is transparent. However, this is not necessary for the present invention. Any material may be used for the outer surface of the package and the surface of the window.

The window can, unlike that described for the second example group, even during deep drawing in the forming device (see Figures 1 a to 1 c) are inserted into an already preformed partial shell and connected to this. For example, the material for the partial shell 603 can be preformed in the cavity. Another material that forms the window is then placed in this preformed Rohhalbschale and then deformed in a second step and connected to this. Such a window can also be inserted later in the recess 650 of the partial shell and connected to it only in a separate step later.

Through this window-like configuration, it is possible to design different surface areas, so that a visually appealing food is obtained.

Advantageously, the window 660 is contained in the area of the respective recess 605 and does not protrude into the flange area 607, 608. As shown in FIG. 13 c, a plurality of windows 660 may also be provided. The windows can be any geometry, e.g. 13a), a heart (see Figure 13b), a quadrilateral (see Figure 13c) and an oval (see Figure 13d) have. In such a sub-shell and different windows with different geometries can be provided.

Example Group 5 With reference to Figures 14 and 15, examples of the first aspect of the invention will be described in more detail.

According to the first aspect of the invention, the two partial shells 703, 704 are made of different materials. For the embodiment of the partial shells or packaging applies to example group 1 to 4 previously said accordingly. Therefore, only the most important aspects are summarized below. In the fourth example group, corresponding features from the first to third example groups are provided with the same reference numerals, but with 700 numbers, wherein z.

In the food package, a food 702 may be packaged, as shown for example in FIG. The food package 701 has a first partial shell 703 and a second partial shell 704. The first partial shell 703 has a first depression 705 and a first flange 707 delimiting the first depression 705. The second partial shell 704 has a second depression 706 and a second depression 708 delimiting the second depression 706. The flanges 707, 708 are in collapsed partial shells 703, 704 to each other and form a protruding edge portion 709. The two flanges 707, 708 may, for. B., so that the first sub-shell 703 is coupled to the second sub-shell 704 via these flanges 707, 708. In the present case, each partial shell 703, 704 is provided with a flange surrounding it in its entirety, so that the respective depression 705, 706 is completely bounded by this flange 707, 708. Such a flange may also only partially limit the respective recess 705, 706 and thus be formed only on partial areas of the outer circumference of the respective partial shell 703, 704. The flanges are presently flat and between the respective flanges 707, 708 and the recess 705, 806 a bend line 710, 71 1 is provided. A proximal flange portion 712 (see Fig. 14b) is connected via the fold line 710, 71 1 with the respective recess 705, 706 and a distal flange portion 713 bounds the respective partial shell 703, 704 on its outer periphery. Of the first and second recesses 705, 706, a cavity 714 is formed in the package 701, in which the food 702 is received. The food 702 can, as shown in relation to example group 1 in FIG. 7, be accommodated in the cavity in such a way that it bears on the inner walls of the cavity 614, in particular contouring the entire surface.

Like the examples of FIGS. 6 to 8, the food 702 may be a chocolate hollow figure, in particular a chocolate Santa Claus. The The chocolate figure does not have to be hollow, but can also be massively filled with liquid or pasty substances. In addition to the Nikolausform can also any other shape, such. Eg egg shape, Easter bunny form, frog or bear form may be provided.

In the example of Figure 14a, the protruding edge portion 709 is not crimped and surrounds the food packaging in the manner of a saturn-shaped ring. FIG. 14b shows a crimped connection of the opposing flanges. Both the beaded protruding edge portion and the non-beaded protruding edge portion may be provided by means of a seal or a seal adhesive

In the packaging shown by way of example two partial shells are provided. The packaging may also be formed from more than two partial shells. Each shell itself forms a unitary integral element.

As far as subsequently turned off on different materials for the different shells, metal, paper or plastic can be used. The term "metal, paper or plastic" is based on the corresponding surface layer, ie, if different materials are used, at least different surface materials of the corresponding sub-shells are used.A multilayer material, for example a laminate laminated with plastic film, can also be used The sub-shells have a different material even if they have superficially different materials, examples of plastic materials are thermoformable plastic film materials such as polyactides (PLA), polycarbonate (APEC), polypropylene (PP), polystyrene (PS), polyester Foil materials preferably have the following strengths: 80 μηη, 100 μηη, 120 μηη, 140 μηη, 150 μηι, 170 μηι, 200 μηι, 350 μηι, 375 μηι, 500 μηι, 520 μηι, 700 μηι The above strengths can each in all Combinations each lower or upper limits of a preferred range of strengths. In particular, a range of 80 to 375 μm is preferred.

The recovery rate of such conventional plastic materials is often insufficient. To address this problem, new compostable materials with similar barrier properties can be used. Examples of such biodegradable Plastic materials, the raw materials from which they are made, and their raw materials are reproduced below:

Material: thermoplastic starch or starch blends; Raw material: potato,

Wheat, corn; Basic material: starch.

The term "biodegradable" is to be distinguished from polyolefin films (in particular PE) which are sometimes used in the packaging industry and which are declared as "oxo-biodegradable" or "oxodegradable." "Oxo-degradable" additives are usually metal ions (cobalt, manganese , Iron, zinc), which accelerate the oxidation and chain degradation in plastics, especially under heat, air and oxygen. The results of this chain degradation are very small, barely visible chain fragments that do not biodegrade (none of the additive manufacturers has so far been able to provide data), but move through our food chain.

In the narrower sense (especially in the field of biomedicine) are referred to as biodegradable materials that are degraded in the body by macrophages, enzymes or hydrolysis within days to a few years. These include, in particular, biogenic polymers such as collagen, fibrin or hyaluronic acid, but also polylactic acid (polylactide), polyglycolide and polycaprolactone. All of the aforementioned materials, which are broadly referred to as biodegradable, may find use. In particular, it is advantageous that these biodegradable materials are also biomaterials from renewable raw materials.

Examples of paper materials are chromo carton, fully bleached pulp, pulp paper, sugarcane paper, thermo-formable fiber material (active polyvalent packaging based on environmentally friendly fibrous material). In particular, thermoformable paper can be used. A thermoformable paper material is a material which, under the action of heat in a forming device, for. B. between two mold halves, such as. As a stamp that is pressed into a cavity can be reshaped, as it is known per se for thermoplastics. Such thermoformable paper materials have recently been used in some specialized fields. In particular, as a thermoformable paper material, a paper material of the company Billerudkorsnäs named "FIBER FORM ^®" which was produced in 2016, used the thermoformable paper material may contain hydrophobic cellulose This film materials preferably have the following strengths:.. Μηη 80, 100 μηη, 120 μηη, 140 μηη, 150 μηη, 170 μηη, 200 μηη, 350 μηη, 375 μηη, 500 μηη The strengths mentioned above can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations, in particular a range of 80 to 500 μηη The paper materials are sometimes thicker than the plastic film materials Examples of metal foil materials are aluminum foil, stainless steel foil, copper foil.

Figures 14a and 14b show non-crimped (Fig. 14a) and flared (Fig. 14b) protruding edge portions of two partial shells of different materials. The two partial shells 703, 704 are made of different materials. The first partial shell 703 is made of a first material 715 and the second partial shell 704 of a second material 716. At the flanges 707, 708, the two sub-shells 703, 704 collide and are coupled together. Any kind of coupling is possible. In FIG. 14, the food 702 lies in the cavity 714 formed by the first depression 705 and the second depression 706. It has been observed by the inventors for the first time that two sub-shells made of different materials can be coupled to each other in such a way that they hold in this received food 702.

For the connection of the partial shell 703, 704, as shown in FIG. 14b, a crimping can be used, for example with a method from FIG. This beading can be done in combination with a seal or without an additional seal. When crimping, as shown in Figure 14b, a flanged edge portion 709 is formed, which has a proximal edge portion 763 and a distal edge portion 764 which is connected via a fold line 762 with the proximal edge portion 763. The flanged edge can also in addition to the outer surface of the package, z. B. be created along the bend line. Such an application can also occur in the non-beaded protruding edge of FIG. 14a.

In addition to sealing and / or flanging and / or application, embossing of the corresponding flange regions can lead to a secure connection of the partial shells 703, 704. In such a stamping an embossing stamp z. B. pressed with a tooth-shaped geometry on the abutting flanges. As a result, the flange deformed three-dimensionally, so that it comes to a kind of toothing of the opposing flanges and thus to a connection. Such embossing, flanging sealing or applying can each be provided as a single means or in combination for connecting the partial shells.

It has remarkably been shown that two partial shells made of different materials can be coupled together via their flanges.

FIGS. 15a and 15b show a front-side partial shell 703 (FIG. 15a) and a rear-side partial shell 704 (FIG. 15b) for food packaging, FIGS. 15c and 15d show a further example of a front-side partial shell 703 (FIG. 15c) or a rear side Partial shell 704 (Figure 15d) for food packaging.

FIGS. 15a and 15b show a first partial shell 703 of the first material 715 and a second partial shell 704 of the second material 716, which is different from the first material. Such sub-shells need not be with a uniform surface without segments, as shown in Figures 15a and 15b. It can also be provided partial shells made of different materials with segmental design. The further example shown in FIGS. 15c and 15d also has partial shells made of different materials. In this case, the first partial shell 703 is a segment-like partial shell, for example of the type of example groups 1 or 2, and the second partial shell constructed of a uniform material, which may also be the same material as one of the surface regions of the first partial shell 703. The different sub-shells are connected to one another via their flanges 707, 708.

Example Group 6

FIGS. 16 and 17 illustrate a sixth group of examples wherein the protruding edge 809 forms a planar element 870 whose geometry is different from a geometry of a crease line 810, 81 1 between the recess 805 and 806 and the flange 807, 808 projecting therefrom is. The examples in Figures 16 and 17 illustrate in particular the sixth aspect of the present invention.

For the embodiment of the partial shells or packaging applies to example group 1 to 5 previously said accordingly. Therefore, only the most important aspects are summarized below. In the fourth example group, corresponding features from the first to third example groups are given the same reference numerals, but with 800 numbers, wherein z. B. the first and second sub-shell with the reference numerals 803 and 804, flanges with the reference numerals 807, 808 and the protruding edge with reference numeral 809 are provided. A food 802 (see Fig. 17b) may be packaged in the food packaging. The food package 801 has a first partial shell 803 and a second partial shell 804. The first sub-shell 803 has a first recess 805 and a first recess

805 limiting first flange 807 on. The second partial shell 804 has a second depression 806 and a second flange 808 delimiting the second depression 806. The flanges 807, 808 abut each other when the partial shells 803, 804 are folded together and form a protruding edge section 809. The two flanges 807, 808 are in this case connected to one another by crimping the protruding edge 809. The beaded edge portion forms a planar element 870 in the present case.

In the present case, each partial shell 803, 804 is provided with a flange surrounding it in its entirety, so that the respective depression 805, 806 is completely bounded by this flange 807, 808. Such a flange can only partially the respective recess 805,

Limit 806 and thus be formed only on portions of the outer periphery of the respective sub-shell 803, 804. The flanges are formed areally and between the respective flanges 807, 808 and the recess 805, 806 is a bending line 810, 81 1st intended. A proximal flange section 812 (see Fig. 14b) is connected via the bend line 810, 81 1 with the respective recess 805, 806 and a distal flange portion 713 bounds the respective partial shell 803, 804 on its outer periphery. Of the first and second recesses 805, 806, a cavity 814 is formed in the package 801, in which the food 802 is received. The food 802 can, as shown in relation to example group 1 in FIG. 7, be accommodated in the cavity in such a way that it rests on the inner walls of the cavity 814, in particular contouring the entire surface.

Likewise, as in the examples of FIGS. 6 to 8, the food 802 may be a chocolate hollow figure, in particular a chocolate Santa Claus. The chocolate figure does not have to be hollow, but can also be massively filled with liquid or pasty substances. In addition to the Nikolausform can also any other shape, such. Eg egg shape, Easter bunny form, frog or bear form may be provided.

In the example of Figures 16 and 17, the protruding edge portion 809 is crimped and thus forms the planar element 870, which surrounds the food packaging in the manner of a saturnformigen ring. The beaded protruding edge portion may be provided by means of a seal or a seal adhesive.

In the packaging shown by way of example two partial shells are provided. The packaging may also be formed from more than two partial shells. Each shell itself forms a unitary integral element. Also for the materials of example group 6, the statements made on example groups 1 to 5 apply accordingly.

As materials metal, paper or plastic can be used. The term "metal, paper or plastic" is based at least on the corresponding surface layer, or a multilayer material can be used, for example a paper sheet laminated with plastic film, or even a single layer of one material and no composite material can be used.

Raw material: starch, sugar; Basic material: starch, sugar.

Wheat, corn; Basic material: starch.

Material: cellophane; Raw material: wood; Basic material: cellulose.

Material: degradable polyester.

The term "biodegradable" is to be distinguished from polyolefin films (in particular PE) which are sometimes used in the packaging industry and which are declared as "oxo-biodegradable" or "oxodegradable.""Oxo-degradable" additives are usually metal ions (cobalt, manganese , Iron, zinc), which accelerate the oxidation and chain degradation in plastics, especially under heat, air and oxygen. Results of this chain degradation are very small, barely visible chain fragments, which do not biodegrade (none of the Additive manufacturer has so far been able to provide data), but through our food chain.

Examples of paper materials are chromo carton, fully bleached pulp, pulp paper, sugarcane paper, thermo-formable fiber material (active polyvalent packaging based on environmentally friendly fibrous material). In particular, thermoformable paper can be used. A thermoformable paper material is a material which, under the action of heat in a forming device, for. B. between two mold halves, such as a stamp that is pressed into a cavity, can be reshaped, as it is known per se for thermoplastics. Such thermoformable paper materials have recently been used in some specialized fields. In particular, was used as a thermoformable paper material, a paper material of the company Billerudkorsnäs named "FIBER FORM ^®", which was produced in 2016. The paper thermoformable material may contain hydrophobic cellulose.

These film materials preferably have the following thicknesses: 12 μm, 15 μm, 18 μm, 20 μm, 25 μm, 30 μm, 50 μm, 70 μm, 100 μm, 200 μm. The abovementioned starches can in each case in each case form lower or upper limits of a preferred range of strengths in all combinations. In particular, a range of 12 to 200 μm is preferred. The metal foil materials are sometimes preferably thinner than the plastic film materials. FIGS. 16a to 16c show an example of a package 801 in which the planar element 870 produced by the beaded protruding edge 809 has a geometry that is different from a geometry of the cavity 814 in the parting plane T,

Figures 17a and 17b show another example of a package 801 in which the planar element 870 resulting from the beaded upstanding edge 809 has a geometry different from a geometry of the cavity 814 in the parting plane T, in which example the distal section lengths of the crimped edge portions are different in length on the different sides.

In the example group 6, the protruding edge portion 809 is crimped so that the distal edge portion 863 is separated from a proximal edge portion 812 (see FIGS. 16c and 17b, respectively) via a fold line 862.

As seen in the examples in Figures 16b and c, the beaded upstanding edge 809 has a different extent in the cross-sectional view shown in Figures 16b and 16c. Here, Fig. 16b is a cross-sectional view taken along the line A-A of Fig. 16a, and Fig. 16c is a cross-sectional view taken along the line C-C in Fig. 16a.

The curling forms the planar element 870. By crimping, in particular the geometry of the fold line 862, regardless of the geometry of the cavity 814 in the region of the parting plane T between the two partial shells 803, 804 can be selected. The beaded element can also be additionally sealed.

In the example illustrated in FIG. 16a, the cavity 814 has a nichol-shaped configuration in plan view at the level of the parting plane, and the planar element 870 has an egg-shaped configuration, the fold line 862 having an oval configuration. In the example in FIGS. 17a and 17b, the planar element 870 has a star-shaped form, because the fold line 871 has a star-shaped contour in plan view and the inner contour of the cavity is round at the level of the parting plane T in its top view. Thus, for example, a round chocolate body can be received in the cavity 814 and the appearance of the product can only be changed via the design of the planar element 870. Thus, for example, a different chocolate shape does not need to be poured depending on the season, but seasonal appearance can be controlled via the planar element 870. The planar element is formed by the beaded edge 809. 17b, the distal edge portion 863, which is formed by the corresponding distal flange portions 812, has different lengths. On the right side in FIG. 17b, this distal edge section 863 is longer in relation to the distal edge section 863 on the left side shown in FIG. 17b. The edge-side end of the distal edge portion 863 abuts the outer wall of the depression 805 almost on the right side in FIG. 17b, the edge-side end of the distal edge portion 863 being spaced on the left side shown in FIG. 17b by a gap therefrom , The design of the packaging according to the example group 6, a conspicuous for the consumer packaging can be provided.

Example group 7

FIGS. 18 and 19 show a seventh group of examples. In the case of the packaging or the partial shells of example group 7, the first partial shell 903 or the second partial shell 904 is made of three different materials. This embodiment is in particular a modification of example groups 1, 2 and 4. The examples in Figures 18 and 19 illustrate in particular the fifth aspect of the present invention.

For the embodiment of the partial shells or packaging applies to example group 1 to 6 previously said accordingly. Therefore, only the most important aspects are summarized below. In the fourth example group, corresponding features from the first to third example groups are provided with the same reference numerals, but with 900 numbers, wherein z. B. the first and second sub-shell with the reference numerals 903 and 904, flanges with the reference numerals 907, 908 and the protruding edge with reference numeral 909 are provided. A food item 902 (see Fig. 18 b, e) may be packed in the food packaging. The distance between the outer surface of the food 902 and the surface of the cavity 914 is shown for clarity only. As in the embodiment of example group 1 (see Fig. 7), the packaging preferably fits snugly or positively against the food 902 and surrounds it completely. The food packaging 901 has a first partial shell 903 and a second partial shell 804. The first partial shell 903 has a first depression 905 and a first flange 907 delimiting the first depression 905. The second partial shell 904 has a second depression 906 and a second depression 906 bounding the second flange 908 up. The flanges 907, 908 are in collapsed partial shells 903, 904 to each other and form a protruding edge portion 909th

In the present case, each partial shell 903, 904 is provided with a flange surrounding it in its entirety, so that the respective depression 905, 906 is completely bounded by this flange 907, 908. Such a flange may also only partially limit the respective indentation 905, 906 and thus be formed only on partial areas of the outer circumference of the respective subshell 903, 904. The flanges are formed in the present area and between the respective flanges 907, 908 and the recess 905, 906 a bend line 910, 91 1 is provided. A proximal flange portion 912 is connected to the respective recess 905, 906 via the bending line 910, 71 1, and a distal flange portion 913 delimits the respective partial shell 903, 904 on its outer circumference. Of the first and second recesses 905, 906, a cavity 914 is formed in the package 901, in which the food 902 is received. As shown in relation to example group 1 in FIG. 7, the food 902 can be received in the cavity in such a way that it bears on the inner walls of the cavity 814 in a contour-forming manner, in particular over the whole area.

Likewise, as in the examples of FIGS. 6 to 8, the food 902 may be a chocolate hollow figure, in particular a chocolate Santa Claus. The chocolate figure does not have to be hollow, but can also be massively filled with liquid or pasty substances. In addition to the Nikolausform can also any other shape, such. Eg egg shape, Easter bunny form, frog or bear form may be provided.

Also for the materials of example group 7, the statements made with respect to example groups 1 to 4 apply accordingly.

In the present case, at least one or both or all partial shells are made of three different materials.

Material: thermoplastic starch or starch blends; Raw material: potato,

Wheat, corn; Basic material: starch.

Material: cellophane; Raw material: wood; Basic material: cellulose.

The term "biodegradable" is to be distinguished from polyolefin films (in particular PE) which are sometimes used in the packaging industry and which are declared as "oxo-biodegradable" or "oxodegradable." "Oxo-degradable" additives are usually metal ions (cobalt, manganese , Iron, zinc) which accelerate oxidation and chain degradation in plastics, especially under heat, air and oxygen. The results of this chain degradation are very small, barely visible chain fragments that do not biodegrade (none of the additive manufacturers has so far been able to provide data), but move through our food chain. In the narrower sense (especially in the field of biomedicine) are referred to as biodegradable materials that are broken down in the body by macrophages, enzymes or hydrolysis within days to a few years. These include v.a. biogenic polymers such as collagen, fibrin or hyaluronic acid, but also polylactic acid (polylactide), polyglycolide and polycaprolactone. All of the aforementioned materials, which are broadly referred to as biodegradable, may find use. In particular, it is advantageous that these biodegradable materials are also biomaterials from renewable raw materials.

Figures 18a to 18e show different views of a food package of two partial shells, wherein Figure 18a shows a frontal view, Figure 18b shows a rear view, Figure 18c shows a side view from a first side, Figure 1 d shows a side view from a first side, Figure 18d is a cross-sectional view along the line DD in Figure 18b, and Figure 18e shows a cross-sectional view along the line EE in Figure 18b, wherein the respective partial shell is made of three segments of different materials.

In the example of FIGS. 18a to 18e, it is shown that the first partial shell 903 and the second partial shell 904 are made of three different materials.

Thus, in each partial shell 903, 904 three segments of different materials are provided. For example, the first material 915 may be paper, the second material 916 may be a plastic material, and the third material may be a metal foil.

The score lines 980, 981 (between the different materials are not limited in their course, the score line at 980 denotes the score line between the third material 917 and another material, here the first and second materials 915, 916, the score line with the Numeral 981 designates the joint line between the first material 915 and another material, in the present case the second and third material 916, 917. For example, as shown in FIG. 18, there may also be a point of impact 982 at which all the different materials meet.

FIGS. 19a to 19c each show a front-side partial shell 903, which has segments of three different materials 915, 915, 915, and FIG. 19d shows a rear-side partial shell 904.

In the examples of FIGS. 19a to 19c, only one joint line 980, 981 is provided between in each case two different materials, and at no point do three different materials come together.

In the example in FIGS. 18a and 18b, the material distribution of the different materials in the individual shells is symmetrical, so that when the two shells are joined together and the flanges 907, 908 are coupled together, a symmetrical distribution of the individual material segments across the two shells takes place ,

In the cross-sectional views in FIG. 18d and FIG. 18e, it can be seen that in the two partial shells 903, 904, the corresponding abutment lines 980 are opposite one another and the area between the opposing abutment lines 980 is perpendicular to the parting plane.

FIGS. 19a, 19b, 19c show different embodiments of partial shells, each of three different materials. FIG. 19d shows a partial shell made from a single, uniform material. This can also be combined with partial shells from FIGS. 19a to 19c and coupled to one another via their flanges.

The design of three different surfaces, an interesting feel can be provided.

Other Aspects The aspects described for the example groups 1 to 7 can be combined in an informal and arbitrary combination with each other and in each case also form an invention.

Although the individual example groups are also covered by the seven groups of claims, all features mentioned in the respective subclaims of each group can also be combined with the features from the other groups. By combining the invention presented in the example groups, a very interesting packaging can be produced for the user.

For all example groups, it is advantageous that the food completely fills the cavity and thus its surface rests on the inner surface of the cavity, contour-forming, in particular full-surface area. The flanges formed in the subshells can be crimped and / or sealed and / or embossed and / or applied in a later step.

With regard to the production process, the processes described in FIGS. 1 and 5 are explained purely by way of example. Any other method which results in the described embodiments may also be used. In particular, the individual partial shells are produced by a kind of deep drawing of the different materials.
