Packaging, method for producing a packaging and device for producing the packaging

The invention relates to a method for producing a packaging, in particular a cup, a corresponding packaging and a device for producing the packaging.

Background of the Invention, Prior Art

Disposable packaging, in particular disposable cups are typically made of coated cardboard / paper or plastic (often made of polystyrene or foamed polystyrene). The coated cardboard cups are said to be recyclable as they contain less than 5% plastic by regulation. The cups are also referred to as Kraftkarton cups. However, the plastic content (e.g., polypropylene) pollutes the environment during manufacture as well as disposal or incineration. The consumer buys a mug that he considers 100% environmentally friendly because he is not informed that these cups contain about 5% plastic.

So far, this comparatively large proportion of plastic in carton packaging and especially in paper / paper cups is absolutely necessary, because he on the one hand the Inner of the cup seals against the exterior of the cup and because on the other hand, when joining the side edges of the cup allows the welding of the two edge regions. For this purpose, a thin (about 18 microns) plastic layer is extruded on the inside of these packages on the inside.

From an ecological point of view, however, it is unsatisfactory that these packages or cups, which are referred to as cardboard packaging or cardboard or paper cups, have a large proportion of plastic.

Therefore, the object is to provide a more ecological, especially liquid and / or grease-tight packaging, preferably in the form of a cup or container, which is made only of renewable and / or biodegradable raw materials to better recycle, dispose of or burning to allow and has the barrier or Resistenzzeigenschaften compared to the contents.

Summary of the invention

The object is achieved by a method according to claim 1, a package according to

Claim 6 and a device according to claim 15.

The inventive method for producing a packaging comprises the following steps:

Punching a slot from a first web (also called stabilizing layer),

Laminating the first web with a second web to form a composite, this second web covering the slot,

Punching out a shell mold from the composite, wherein the shell mold defines the dimensions of a wall of the packaging and the shell mold has two side edges,

Removing the jacket form from the composite, wherein in the area of the former slot the second panel projects beyond the first panel and forms a tab, Creating an edge protector in the region of the side edges, wherein the tab is wrapped around an end region of the first web,

- Forms the packaging of the shell mold, wherein the two side edges are merged and connected overlapping.

A packaging according to the invention has a lateral surface made of composite material which has two side edges. The side edges are glued together overlapping in a connection area. An outer layer of the lateral surface is made of the material of a first web. The material of the first web is laminated on the inwardly facing side of the lateral surface with a second web and the second web is formed in the region of one of the side edges to a tab which is placed around the side edge as edge protection. The following sequence of layers results from the inside to the outside in the connection area: second path, material of the first path, tab of the material of the second path, second path and material of the first path.

In the respective subclaims further advantageous embodiments of the invention are listed.

The invention is particularly suitable for the production of drinking and vending cups for cold and hot drinks.

Detailed description of the exemplary embodiments

In the following, the principle of the invention will be described with reference to a first embodiment. Previously, terms used in the specification and claims are defined.

According to the invention, a liquid-repellent sheet is used. For example, wax paper, oil paper, parchment paper (or glassine) or other at least temporary barrier or Resistenzeigenschaften exhibiting, in particular water and grease-tight (repellent) paper can be used.

Wax paper: Predominantly wood-free paper that is coated or impregnated with paraffin, wax or additives on the surface. This makes it water repellent.

Oil paper: oil impregnated paper. Waterproof Paper: Mainly used for packaging. It is made impermeable to aqueous liquids by impregnation or lamination. An example is silicone paper.

Parchment Paper: Paper rendered water repellent by acid bath.

When the term punching is used below, it also means other methods which lead to comparable results. Instead of punching the first web or the composite, one can e.g. also work with a computer-controlled laser or high-pressure cutting method.

In the following, a method according to the invention for producing a packaging 20 is described. In connection with the description of this method, reference is made to the schematic figures IA to IG. The method is described by means of a series machine production of several paper cups 20, although it can be applied analogously to the individual production of only one paper cup 20.

In a first step, a slot 12 is punched out of a first web 11. In Fig. IA, this first web is shown in plan view.

The first web has a thickness which gives it sufficient stability and, if desired, heat-insulating properties for a cup 20. The first web may be made of a paper, cardboard, nonwoven, molded fiber or other from renewable and / or preferably biodegradable raw materials and may contain recycled material, especially recycled fiber material and / or preferably fibrous material, not for direct contact suitable for food. Direct contact of the contents with the first web is avoided by the second web.

Typically, the first web 11 has a thickness between 200-300 μm (160-240 g / m ² ) This first web 11 is made paper or cardboard. This first web 11 may comprise one or more paper and / or cardboard layers. Preferably, the first web 11 comprises kraft paper. It is possible to make the first web 11 of recycled material, which is an important aspect of the invention.

Then, the first web 11 is laminated with a second web 13 to produce a so-called composite 10. The lamination is made so that this second path 13 covers the slot 12. Therefore, in Fig. 18, the borders of the slots 12 are shown in dashed lines. The composite 10 is shown in FIG. 1B. Here, the second lane 13 completely covers the first lane 11. The second web 13 should cover at least that portion of the first web 11 which later comes into contact with liquid inside the cup 20.

Typically, the second web 13 has a thickness between 40-70 μm (35-57 g / m ² ).

The second web 13 has at least for a defined period of time barrier and / or resistance properties against at least a portion of the contents and can be made in one or more layers, in particular renewable and / or preferably biodegradable raw materials and also paper, cardboard, cardboard, fine cardboard or the like.

The second web can be impregnated or coated on at least one side with, for example, fluorocarbons, microwaxes, polymers, saturated and / or unsaturated fatty acids or fatty acid esters, vegetable oils such as olive oil or castor oil, substances with functional groups preferably based on polyvinyl acetate (PVAc), ethylene vinyl alcohols (EVOH), polyvinyl alcohols (PVOH), polyethylene glycol (PEG), glycerol, PLA or other especially renewable and / or biodegradable base, or the like, which may be present as aqueous, oily or other solutions and / or dispersions. It is also conceivable that the first web is equipped in such a way to make them insensitive to humidity, for example, or to protect a printed image.

It is also conceivable that the first web 11 is equipped on two sides with a second web 13, as shown in Fig. 9. By such a configuration, a package of this material construction is not only insensitive to the contents, but also to environmental influences during handling and storage. The two second webs 13 can be connected to one another at the cut edges by one or several folds or the like. An open edge of the first track is avoided at all costs. It is also conceivable that a second web 13 is transferred to the other second web 13 at the cutting edges of the composite and connected thereto. Likewise, a connection of the two second webs 13 in the form of a fin seam is conceivable.

It comes Kaschierklebstoff, adhesion promoter, sealing material or the like used to laminate the first web 11 with the second web 13, to connect in the sense of the entire surface. Preferably, a laminating adhesive is used which is food compatible or suitable. Particularly preferred is the use of a Kaschierklebstoffs, which is recyclable together with the cup 20 and / or residue-free.

DIPB-free dispersion adhesives (DIPB = diisobutyl phthalate) are preferably used as laminating adhesive and / or DIPB-free paper and paperboard grades.

The adhesion promoter or adhesive layer can be made from a renewable raw materials and / or biodegradable substances and have barrier properties and / or be water-soluble. Adhesive or adhesive layer may be an adhesive of or based on starch, lignin, rubber, casein, dextrin, cellulose acetates, bone glue, fish glue, citric acid, polyethylene glycol (PEG), glycerol, soy and / or gelatine, their mixtures and / or modifications, an adhesive based on biopolymers made from starch, thermoplastic starch, polylactic acid (PLA), crystalline PLA, amorphous PLA using D-PLA, L-PLA and mixtures thereof Polycaprolactone (PCL), Polyhydroxyalkanoids (PHA), Polyhydroxybutyrate (PHB), biodegradable polyesters and / or copolyesters, aliphatic copolyesters, aromatic copolyesters and / or aromatic-aliphatic copolyesters or their blends and / or that the adhesive functional groups based on polyvinyl acetates (PVAc), ethylene vinyl alcohols (EVOH) and / or polyvinyl alcohols (PVOH) are used, wherein the adhesive as a hotmelt, coldmelt, solution or dispersion with water or other L may be added to a plasticizer and / or from renewable resources and / or biodegradable and / or that the adhesive is reactivated by heat, ultrasound or other sources.

The two webs can be laminated, laminated, glued, sealed, UV sealed, ultrasonically sealed or otherwise applied.

In a further step, which is indicated in Fig. IC, now a so-called shell mold 14 is punched out of the composite 10 (also referred to as punching the flat shape). The shell mold 14 defines the dimensions of a wall (or shell surface) of the cup 20 to be manufactured.

In Fig. 5 is indicated that a rectangular shell mold 14 results in a paper cup 20 with a vertical side wall. In Fig. 6 it is indicated that a curved shell mold 14 results in a paper cup 20 with an oblique side wall. In the extreme case, which is indicated in Fig. 7, a conical paper cup 20 can be formed, as it is often offered for example in connection with water dispensers for single use. The jacket mold 14 has two lateral edges 15, 16, as shown in FIG. 1C and FIG. 1D. In addition to these side edges 15, 16, the shell mold 14 has at least one upper edge 19.1 (see, for example, FIG. 7). Often, the shell mold 14 also has a lower edge 19.2, as shown in Figures 5 and 6.

After punching out of the shell mold 14, this is taken out of the composite 10 by machine or manually, wherein in the region of the former slot 12 the second paper web 13 projects beyond the first paper web 11 and forms a type of tab 17 there. In Fig. ID, a shell mold 14 after removal from the composite 10 is shown.

Now an edge protection in the region of the side edges 15, 16 is generated, for which purpose the tab 17 is placed around an end region of the first paper web 11. This is preferably done when forming the paper cup 20 from the shell mold 14, as shown in Figures IE and IF.

This step may be performed, for example, in a cup machine. In Fig. IE, the state shortly before the merging of the two side edges 15, 16 is shown. It can be seen in Fig. IE that the inwardly facing second web forms the flap 17. When forming the sleeve of the paper cup 20 that side edge 15, which has no tab 17, is guided past the side edge 16 with the tab 17 and connected.

In Fig. IG, which shows a schematic, not to scale representation of the junction with edge protection, it can be seen that the side edge 15 is guided behind the side edge 16 with tab 17 and the tab 17 was bent or folded as edge protection to the rear. This creates a new side edge, which is designated here by the reference numeral 18. By folding or bending the tab 17, which is made of the material of the second web 13, the side edge is protected against ingress of moisture. This is essential, since this side edge 18 comes into contact with liquid, which is stored inside the paper cup 20.

The edge protector is characterized in that the tab 17, which consists of the material of the second web, is guided around a side edge and thereby describes a 180 degree change of direction.

The following sequence of layers results in the connection region, viewed from the inside to the outside: paper layer 13, material of the first paper web 11, tab 17 made of the material of the paper layer 13, paper layer 13 and material of the first web 11.

In FIGS. 2A to 2C, the shaping of the paper cup 20 is shown in an enlarged detail, wherein the two side edges 15, 16 are brought together and connected in an overlapping manner step by step. In Fig. 2A it is shown that here the side edge 15 approaches from the left so that it leads with the laminated inside the tab 17 to the rear to form the new side edge 18. The direction of movement of the side edge 15 is indicated by a pointing to the right arrow. Fig. 2B shows another intermediate step and Fig. 2C shows the final result. After forming the paper cup 20 and creating the edge protector with the tab 17, the laminated side 13 points inwards and the unbacked back of the first web 11 outwards.

When molding the paper cup 20 and the cup bottom can be inserted, which is not shown here in the figures, since it is a conventional process that is performed automatically by so-called cup machines.

The bottom of the cup is prepared and inserted as follows. The mantle shape of the cup bottom can be punched out of a roll of material and then deep-drawn. Then the prefabricated cup bottom is inserted from below into the sleeve (made according to the invention). Before glue is applied. After this Inserting the cup bottom, this is preferably crimped and pressed to form a permanent, firm and tight connection with the sleeve.

In Fig. 3 it can be seen that the angle W of the lateral surface, which surrounds the cup 20, approximately corresponds to the angle W of the slots 12 which have been punched out of the first paper web 11 (see Fig. IA). In a cup 20 having a vertical side wall (see Fig. 5), the slots 12 are parallel to the longitudinal direction L of the first paper web 11, i.e., the first paper web 11 is elongated. the angle W is here equal to O.

In Fig. 4 is purely schematically indicated that the length LS of the tab 17 may be shorter than the length LK of the side edge. This may be the case, for example, if a cup bottom is to be used in the lower region of the paper cup 20, which has a small distance to the lower edge. In Fig. 3 and in Fig. 4, the position of such a cup bottom is indicated by a dotted line 21. In this case, the tab 17 does not have to be guided all the way to the lower edge 19.2 along the side edge 16, since it does not need any edge protection below the bottom.

The adhesive used for lamination may also be used to create the edge protector and shape the paper cup 20. It can also be used here but another adhesive. In Fig. 8 is indicated in a highly schematized magnification, where the adhesive 22 can be applied to allow the forming of the edge protection and the forming of the paper cup 20.

According to the invention, the first web 11 and / or the second web 13 can be printed in an intermediate step, preferably a recyclable dye is used for printing.

According to the invention, the webs can be provided as sheets and / or rolls. Preferably, the first method steps are carried out to then to stock the semi-finished product in the condition shown in Fig. 1C or to send it to a customer. There, if necessary, the last steps of the process are carried out, for example using a conventional cupping machine.

The inventive method can be easily integrated into a machine manufacturing plant.

Depending on the embodiment, the paper cups 20 may have a rolled edge. The rolled edge is made at the upper edge 19.1.

The present invention can also be applied to other packaging 20.

It is conceivable that the first web 11 dissolves upon prolonged contact with water or at least easily compostable. Due to the then missing first web 11, the bonding agent layer and the second web 13 can then also be dissolved and / or biodegraded.

The barrier or resistance properties of the second web 13 exist at least for a defined period of use. The second web 13 may be single or multi-layered.
