Description

Plastic element for packaging and packaging with such

Plastic element

The invention relates to a plastic element for a packaging, comprising: a base body made of plastic, and a flange for fastening a

Composite material of a package, wherein the plastic element is made of a thermoplastic material.

The invention further relates to a packaging with a plastic element, comprising: at least one region made of a composite material, and at least one plastic element, wherein the composite material at least one carrier layer of a cellulosic fibrous material, preferably of paper, cardboard or cardboard and on both sides of the carrier layer in each case at least a

Plastic layer, wherein the plastic element has a flange for

Attachment of the composite material, and wherein the composite material is connected to the flange of the plastic element.

Packaging can be done in different ways and in different ways

Materials are produced. A widespread possibility of their production is to produce a blank from the packaging material, from which by folding and further steps first a packing jacket and finally a packaging is formed. This production method has the advantage, among other things, that the blanks and packing shells are very flat and can thus be stacked to save space. In this way, the blanks or packing shells can be produced at a different location than the folding and filling of the

Packing coats done. As a material often composites or

Composite materials used, for example, a composite of several thin layers of paper, cardboard, plastic or metal, especially aluminum. Such packages are particularly in the food industry large In addition to the requirement for a package to keep its contents safe and protected from environmental influences, increasing packaging requirements are to provide information about the condition of its contents. For example, many food packages are given a "best before date" that allows the customer to know when the content is expected to be at least stable

The expiry date therefore corresponds to a recommended exhaustion period and is therefore to be distinguished from an "expiry date"

Source of information are so-called "originality victories", which are destroyed when opening a package for the first time, so that a customer can recognize whether a

Packaging has been previously opened.

However, these known from the prior art solutions have the disadvantage that they inform the customer very imprecise or very indirect about the state of the contents of the package. For example, that will

Best before date based on standardized storage conditions (eg defined storage temperature). Deviations from these standardized storage conditions that occur in practice therefore remain

unconsidered. The above-mentioned originality seals also do not provide information as to when the packaging was first opened, so that it is unclear, for example in the case of a "broken" packaging, whether the remaining contents are still edible.

To avoid these disadvantages, different solutions are known in the field of packaging technology. However, these solutions have not been used, especially for cost reasons in disposable packaging of bonding material.

Against the background of these disadvantages, the invention has the object, the plastic element described above and the packaging described above in such a way and further develop that even with disposable packaging cost-effective way is created to obtain information about the condition of the contents of the packaging.

This object is achieved with a plastic element according to the preamble of

Claim 1, characterized in that an electrical, in particular electronic element, which is arranged on the plastic element or is integrated in the plastic element.

The invention relates to a plastic element for a packaging, in particular for a disposable packaging made of composite material. Preferably, this has

Composite material at least one carrier layer of a cellulose-containing

Fiber material, preferably made of paper, cardboard or cardboard, which is covered on both sides by at least one plastic layer. The composite material may also comprise a layer of aluminum. The plastic element initially comprises a base body made of plastic. In addition, the plastic element comprises a flange for fastening a composite material of a package.

Preferably, the flange is arranged on the base body. The plastic element is made of a thermoplastic material, such as PP

(Polypropylene) or PE (polyethylene), especially PE-HD (high density polyethylene). For example, these materials have the advantage of free and variable shaping (e.g., by injection molding). The plastics mentioned may contain fillers ("fillers") which are produced from other materials (eg mineral materials) .The plastic element may be single-layered or multi-layered The plastic element is supplemented according to the invention by an electrical, in particular electronic, element attached to the plastic element is arranged or integrated in the plastic element

Plastic element can be understood, for example, an arrangement in which the electrical element contacts the plastic element. For example, the electrical element is materially bonded to the plastic element (e.g.

glued) and / or the electrical element is positively connected to the Plastic element connected (eg trapped). The electrical element can be arranged on the outside (side facing away from the content of the packaging) or on the inside (side of the content of the packaging) of the plastic element. Alternatively, the electrical element may be integrated into the plastic element, which is to be understood as an arrangement in which the electrical

Element is completely surrounded by the material of the plastic element. This can be achieved, for example, by integrating the electrical element in the plastic element during the production of the plastic element, for example by inserting or inserting the electrical element into the (still) viscous plastic or by inserting the electrical element into the injection mold. By encapsulating inserts arise hybrid components made of plastic and metal (the electrical element may have metallic components). The electrical element is arranged in particular on the main body of the plastic element or integrated into the main body of the plastic element. The electrical, in particular electronic element can be, for example, a chip with integrated circuits.

According to one embodiment of the plastic element is provided that the electrical, in particular electronic element comprises a sensor. The sensor may be, for example, a pressure sensor, a pH sensor, a

Temperature sensor, a sensor for measuring the oxygen content, a sensor for measuring the electrical conductivity, a sensor for measuring the proportion of one or more vitamins / trace elements or a sensor for measuring metabolic products act. A sensor (also called a "sensor") serves the purpose of qualitatively and / or quantitatively detecting certain physical or chemical properties of the contents of the packaging: it can be a passive sensor (requires no auxiliary energy) or an active sensor (requires auxiliary energy The auxiliary energy can be provided by an integrated battery or provided by external activation (eg by electromagnetic induction) Depending on the size to be measured and the measuring principle to be used, the sensor can be located on the surface, in particular on the inside of the sensor Be arranged plastic element (eg for contacting measuring methods) or be integrated into the plastic element (eg for non-contact measuring method). It is advantageous to determine the current quality of the product in order to determine the current quality

Food two measured values are used. This may be the same parameter, the sensor measuring the measured value, for example a pH, for the first time e.g. upon contact with the product and then one

Change of the measured value without knowing the actual quantitative value. The sensor is therefore preferably a sensor which detects a qualitative change of a measured value. Therefore, it may occasionally be advantageous if the sensor is formed to determine at least one relative value of the measured value relative to an initial measured value.

According to a further embodiment of the plastic element is provided that the electrical, in particular electronic element comprises a transmitter. A transmitter serves the purpose of transforming an input (e.g., a signal measured by a sensor) into an output (e.g., an electromagnetic wave). For example, the conversion may be necessary to wirelessly transmit a measured conducted signal.

Therefore, transmitters are sometimes also referred to as transmitters or transmitters. The transmitter may, for example, an oscillator, an amplifier, a

Modulator and have an antenna.

According to a further embodiment of the plastic element is provided that the electrical, in particular electronic element comprises an antenna. An antenna serves the purpose of emitting and receiving electromagnetic waves. Since the required brew size of the antenna depends on the wavelength of the electromagnetic waves transmitted or received therewith, a separate antenna over an integrated antenna is preferred (e.g., one to the other)

Transmitter integrated antenna). Preferably, the antenna has a length of at least 10 mm, in particular of at least 15 mm or at least 20 mm. In order to reduce the angular dependence of the antenna, it may be provided that the antenna is at least partially circular in shape. For example, the antenna may be disposed around the pouring opening when the plastic element is a pouring element of a package. The plastic element can be supplemented by at least one electrical conductor which connects the electrical, in particular electronic element with the flange. The electrical conductor serves the purpose of establishing an electrical connection between the electrical element and the flange to there an electrical

To be able to connect to the composite material to be fastened to the flange. The electrical conductor may for example be made of metal, in particular copper or aluminum. For example, the electrical conductor is formed by a wire. Preferably, the plastic element has two electrical conductors which connect the electrical element to the flange.

Preferably, the at least one electrical conductor is at least partially integrated in the plastic element - in particular in its base body.

For this purpose, it is further proposed that the electrical conductor at least

is arranged in sections on the contact side of the flange. Under the

Contact side of the flange is understood to be that side of the flange to which the composite material of the packaging is attached. Depending on the configuration, this can be the inside of the flange or the outside of the flange. If a plurality of electrical conductors are provided, preferably all electrical conductors are arranged at least in sections on the contact side of the flange. In this case, it is preferred that the electrical conductors do not overlap, but extend over different portions of the flange. For example, in the case of a quadrangular flange, it may be provided that the first electrical conductor extends over two adjacent sides of the flange, while the second electrical conductor extends over the other two sides. In this way one becomes

Reverse polarity protection ensures and short circuits are avoided. According to one embodiment of the plastic element is provided that the

Plastic element is a pouring a packaging with a pouring opening. A pouring element serves the purpose of being able to pour out the contents contained in the packaging. The pouring element can be designed in several parts and include, for example, a screw cap next to the main body.

Alternatively, it may be provided that the plastic element is a bottom element of a package. The bottom element of the packaging serves the purpose of being able to store the pack safely and designed to be as dimensionally stable as possible. The pouring element (and its flange) and / or the bottom element (and its flange) determine the shape of the package; they can be square - especially

square - round, or oval shaped.

The object described at the outset is also achieved by a packaging with a plastic element, comprising: at least one region of one

Composite material, and at least one plastic element, wherein the composite material at least one carrier layer made of a cellulose-containing fiber material,

preferably made of paper, cardboard or cardboard and on both sides of the

Carrier layer each having at least one plastic layer, wherein the

Plastic element has a flange for attachment of the composite material, and wherein the composite material is connected to the flange of the plastic element. It is therefore a packaging which is partly made of plastic parts and partly of a composite material. The composite may, for example, have a thickness in the range between 150 g / m ² and 400 g / m ² ,

in particular between 200 g / m ² and 250 g / m ² . The packaging is characterized by an electrical, in particular electronic element, which is arranged on the plastic element or integrated in the plastic element. In addition to the properties already described above, the arrangement of the electrical element on the plastic part or the integration of the electronic element in the plastic part has the advantage that the local arrangement is easier to produce than an arrangement in the composite material. This is in particular because many electrical elements have a certain thickness, the one Complicate integration into the very thin composite materials. The composite material may for example have a thickness in the range between 0.2 mm to 1.0 mm, in particular between 0.3 mm and 0.8 mm. In addition, the composite material is typically produced in large quantities as roll stock by joining multiple layers of different materials together. Only then is the composite material to be produced with respect to the different ones

However, packaging sizes should be tailored, but integration of the electrical elements into the composite (e.g., between two layers of composite) would have to take place prior to trimming. Again, this would complicate a precise arrangement of the electrical elements in the composite material. For these reasons, it is advantageous to arrange the electrical elements in or on the plastic elements. Another advantage is that the wireless or wireless

Transmission of signals through the plastic elements to the outside (e.g., to a consumer device such as a smartphone) is easier than through the shielding aluminum layer provided in some composite materials.

According to one embodiment of the packaging, it is provided that the plastic element is a plastic element according to one of claims 1 to 8. The plastic element described above is suitable in all the embodiments shown in a special way for the production of packaging. This is due, in particular, to the fact that the plastic element has a flange on which the composite material of the

Packaging can be attached (e.g., glued). The plastic element is therefore structurally oriented for connection to a composite material.

Another embodiment of the packaging provides that the electrical, in particular electronic element is arranged such that it makes contact with the contents of

Packaging or that the electrical, in particular electronic element is arranged such that it has no contact with the contents of the package. A

Arrangement with contact to the contents of the packaging can be achieved, for example, by the fact that the electrical element on the inside of the Plastic element, in particular on the inside of the base body is arranged. In this way, the electrical element can touch the contents of the packaging, for example the product (in the lower region of the packaging) or air or another gas mixture (in the upper region of the packaging). The contacting arrangement may be useful, for example, if the electrical element is a sensor intended to detect certain physical or chemical properties of the contents of the packaging by a contacting measuring method. An arrangement without contact with the contents of the packaging, however, can be achieved, for example, by the fact that the electrical element on the outside of the

Plastic element is arranged or is completely integrated in the plastic element. In particular, the electrical element can be arranged on the outside of the main body or be completely integrated into the main body. In this way, contact between the electrical element and the contents of the package is reliably prevented. The non-contact arrangement can

For example, be useful if the operation of the electrical element could be affected by the contents of the package or if the contents of the package must not come into contact with the electrical element for reasons of hygiene. According to an embodiment of the packaging, it is provided that the region of composite material is a circumferential lateral surface. By providing a shell of composite material, the package is made of composite material along its entire circumference. Due to the very cost-effective production of composite material, the largest possible use of composite material has cost advantages in particular. In addition, a particularly low weight is made possible by the largest possible use of composite material. The lateral surface may be continuously curved (eg round cross-section, oval cross-section) or be composed of a plurality of side surfaces separated by folded edges (eg quadrangular, in particular square cross-section). For this embodiment, it is further proposed that the composite material in the region of the lateral surface has a longitudinal seam. The longitudinal seam is created by folding a blank of composite material and connecting the two abutting edges. Preferably, the longitudinal seam extends in the vertical direction, ie from the bottom region in the direction of

Gable area of the packaging. The composite material has at least one layer of paper or paperboard which may be covered at the edge of the longitudinal seam running inside the package jacket. The cover of the

Paper layer or cardboard layer has the purpose to avoid contact between the contents of the package and this layer. This serves, on the one hand, to prevent leakage of liquid through the paper layer or paperboard layer which is not liquid-tight and, on the other hand, to protect the contents of the packaging from contamination by the paper layer or paperboard layer (for example fibers of the pulp). The layer of paper or paperboard can be covered by a sealing strip and / or by flipping the composite material in the region of the longitudinal seam. One way of covering is to attach a separate one

Sealing strip. The sealing strip may for example be made of the same material as the innermost layer of the composite material and glued or welded to this position.

With regard to the longitudinal seam, it is further proposed that the composite material is peeled and / or folded over in the region of the longitudinal seam and / or one

Has sealing strip. Under a "shelled" composite material is a

Composite understood that has less layers in the peeled area than in the other areas. The peeling has particular in the range of

Overlaps of multiple layers of material the advantage of a less strong

Increase in thickness. Therefore, the use of peeled is particularly advantageous

Composite material, when the composite material is folded over or folded over - for example in the region of the longitudinal seam. The refolding ensures that the layer of paper or cardboard is covered. In this way, no longer all layers occur at the edge of the longitudinal seam extending inside the package. but only the innermost layer of the composite material to the fore. However, the innermost layer must anyway be made of a material that is suitable for contact with the contents of the packaging. The sealing strip may be a plastic strip which is connected to the inside of the

Bonded composite material, in particular glued or sealed and the longitudinal seam seals.

According to a further embodiment of the packaging, it is provided that the

Composite material has at least one electrical conductor. The electrical conductor serves the purpose of conducting electrical current through the composite material, for example, from the bottom region of the packaging to the gable region of the

Packaging. In this way, electrical elements such as sensors, transmitters and the like can be interconnected. The electrical conductor may be, for example, a thin wire or a thin strip of an electrically conductive material such as metal, in particular copper or aluminum. Preferably, the electrical conductor extends through the entire length of the composite material. This has the particular advantage of a simple production, since the conductor in the manufacture of the composite material between two layers or layers of the composite material can be placed. The composite material may have two or more electrical conductors; In this case, the electrical conductors are preferably parallel to one another. This has the advantage that the

Do not cut or touch the electrical conductor. Alternatively to a

Integration between multiple layers or layers of the composite material during manufacture, the electrical conductor can also be retrofitted in the field of

Be arranged longitudinal seam, be. This can be achieved, for example, by folding over or folding over the composite material in the region of the longitudinal seam, and the electrical conductor in the region of the folding or

Folding is arranged. If a plurality of electrical conductors are provided, the conductors are preferably electrically isolated from each other, for example by a plastic layer. The electrical conductor can also be in a plastic strip or Integrated sealing strip, which is glued to the inside of the composite material.

According to a further embodiment of the packaging, it is provided that the

Composite material at least one layer of an electrically conductive material, in particular aluminum. On the one hand, the aluminum layer has the advantage that the contents of the packaging are protected particularly well against light and oxygen. Another advantage is that an aluminum layer is electrically conductive and thus can take over the function of an electrical conductor. In order to get two electrical conductors, it is sufficient, besides the

Aluminum layer only provide another electrical conductor. If a plurality of electrical conductors are provided, the conductors are preferably electrically isolated from each other, for example by a plastic layer. According to a further embodiment of the packaging is finally proposed that the electrical conductor and / or the layer of electrically conductive material at least in the region of the plastic element on the contact side of the

Composite material is arranged. This embodiment is intended to ensure that the electrically conductive regions of the composite material with the electrically conductive regions of the plastic element (esp. The electrical conductors) in

Contact are when the composite material is connected to the plastic element. When joining composite material and plastic element so an electrically conductive contact point should be formed. The invention will now be described with reference to a preferred one

The plastic element 1 has a base body 2 and a screw cap 3. The screw cap 3 is screwed onto a thread (not shown in FIG. 1) and can be unscrewed from the base body 2. The main body 2 has a circumferential flange 4, which serves for fastening a composite material of a package. In the plastic element 1 shown in Fig. 1, the flange 4 has the shape of a truncated pyramid. In each of the four corner regions, a projection 5 is integrally formed on the flange 4. The lugs 5 serve the connection between the gable area of a

Packing jacket and the flange 4 to improve. The plastic element 1 also has a tamper-evident seal 6 which connects the base body 2 to the screw cap 3 via two thin material bridges 7. Upon initial opening, the material bridges 7 are destroyed, so that a customer can easily recognize whether a provided with this pouring package has been previously opened before. Such plastic elements 1 are known for example from EP 3 112 283 AI or EP 2 637 854 AI.
