[0150] FIG. 11b a schematic view of an arrangement of transmitting elements on an endless belt;
[0151] FIG. 1 shows a schematic view of a layered structure of a package laminate (package material). The layer structure can have a carrier layer 2, an outer top layer 4, an inner top layer 6 and a barrier layer 8. The carrier layer 2 is preferably made of a carrier material such as cardboard. The top layers 4, 6 are made of plastic, for example PE, and the barrier layer 8 is metallic, for example aluminium. For further details of the layers, please refer to the explanations above. It goes without saying that this layer structure is purely exemplary.
[0152] FIG. 1 shows that the top layer 6, for example, has an integrated sensor 10. The sensor 10 has an area 10a that breaks through the top layer 6 and thus lies on the surface of the top layer. However, the sensor 10 can also have an area 10b which is covered by the surface layer 6. It is also possible that only an area 10a or an area 10b of the sensor 10 is provided. In the range 10a a direct measurement on the product is possible and in the range 10b an indirect measurement on the product is possible.
[0153] As can be seen, the sensor 10 is applied to the barrier layer 8. The sensor 10 is isolated from the barrier layer by an insulator. Starting from the sensor 10, two wires 12a, b extend along the barrier layer 8. The wires 12a, b can in particular be foil conductors which are insulated and lie insulated on the barrier layer 8.
[0154] To contact the sensor 10 with an electrical element beyond the barrier layer 8, it is necessary to perforate the barrier layer 8. At the same time, the two conductors 12a, b must remain electrically isolated from each other to enable signal transmission. Such a contacting is shown as an example in FIG. 2.
[0155] FIG. 2 also shows a carrier layer 2, a barrier layer 8 and a top layer 6. Furthermore a sensor 10 is provided which breaks through the top layer 6 in a range of 10a.
[0156] In contrast to FIG. 1, however, conductors 12a and 12b are not formed as foil conductors but, for example, as printed conductors from top layer 8. FIG. 2 also shows that the barrier layer is separated at a separation area 14. The separation area 14 preferably runs parallel to a transverse or longitudinal seam and preferably extends over an entire blank from an upper edge to a lower edge or between two side edges. This ensures that the barrier layer 8 is divided into two areas which are electrically insulated from each other by the separation area 14. This makes it possible to contact conductor 12a with a first part of barrier layer 8 and conductor 12b with a second area. This contact can be made, for example, with the aid of pins that break through the top layer 6.
[0157] On the other side of barrier layer 8, in the area of carrier layer 2, the two areas of barrier layer 8 can also be contacted and conductor 12a is continued through conductor 12a and conductor 12b through conductor 12b. The conductor 12a is electrically short-circuited to the conductor 12a and the conductor 12b is electrically short-circuited to the conductor 12b. An electrical insulation is provided between the conductors 12a, b, e.g. by the separation area 14 in the barrier layer 8.
[0158] The conductors 12a, 12b contact an electrical element, for example a transmitter 16, which can be equipped with a processor, a memory and an antenna.
[0159] The transmitter 16 can, for example, read measured values from the sensor 10 via the conductors 12a, a, 12b, b and make them available wirelessly via an antenna.
[0160] FIG. 3 shows another possibility of contacting conductors on both sides of the barrier layer 8. In FIG. 3, the barrier layer 8 is provided with an opening 18. The opening 18 can, for example, be in the form of a punched hole, for example round or angular. Through this opening 18 a contact element 20 can be inserted which is insulated from the barrier layer 8, e.g. via an air gap. Contact element 20 can be connected to conductor 12a on the one hand and conductor 12a on the other hand. This contact element 20 is used to connect the two conductors 12a, a. The same or an alternative can of course also be done for conductors 12b, b.
[0161] FIG. 4 shows another embodiment in which contacting with a contact element 20 can take place directly in the area 10b of the sensor 10. Here the sensor 10 with its range 10b can be arranged above the opening 18. The contact element 20 can be connected directly to a contact on the sensor 10. Furthermore, the contact element 20 establishes a connection with a conductor 12a. Contact element 20 can be part of sensor 10.
[0162] FIG. 5 shows a top view of a blank, for example from the sides of the top layer 6. The blank 22 is characterised by folding edges 22a and folds 22b shown in dotted lines. The type of blank 22 is well known. However, it can be seen that at a longitudinal edge 22c or at a transverse edge 22d there is a preferred area 22e shown with dotted lines, in which the separation area 14 or the opening 18 is arranged. Particularly in the area of the longitudinal edge 22c, the packaging is sealed with the opposite longitudinal edge so that a sealing seam is formed there. In the area of this sealing seam, the separation area 14 or the opening 18 is preferably arranged.
[0163] It is also possible to form the contact by means of an element projecting beyond a longitudinal edge 22c or a transverse edge 22d, whereby this element can be bent over after sealing. FIG. 6a shows such an example. FIG. 6a shows a prefolded package sleeve in which the blank 22 is already prefolded in large parts. It can also be seen that a contact element 20 is connected to the conductors 12a, 12b on the one hand with a sensor 10 and on the other hand projects beyond the longitudinal edge 22c. This contact element 20 can, for example, be provided on top layer 6 or between top layer 6 and barrier layer 8 in the production process.
[0164] The packaging is then sealed along the longitudinal edge 22c, as shown in FIG. 6b. The edges are preferably sealed together so that a top layer 6 is heat-sealed with a top layer 4. After the sealing process, the contact element 20 is then located inside the package on the one hand and outside the package on the other and is passed through the sealing seam. Finally, the protruding part can be placed around the longitudinal edge 22c.
[0165] It is also possible to provide a sealing strip 24 with the lines 12a, b. FIG. 7a shows another example of a package sleeve in which the longitudinal edges are laid on top of each other. In this example, blank 22 is sealed by a sealing strip 24 which is placed over the seam. The sealing strip 24 preferably runs along the entire longitudinal seam 22c. The sealing strip 24 can be arranged so that it protrudes beyond the upper or lower edge. After sealing, the sealing strip 24 is arranged along the longitudinal edge and protrudes beyond the transverse edge 22d of the package sleeve, as shown by the dashed lines. After closing the transverse edge, the sealing strip can be contacted from the outside and in particular the lines 12a, b. If there is no longitudinal seam, e.g. in a tube, a contact element 20 formed as a strip can also protrude from a transverse edge 22d instead of as shown in FIG. 6b. The contact element 20 is formed as a strip. Then the contact element 20 can be provided without sealing function.
[0166] FIG. 7b shows a cut through such a sealing strip 24. It can be seen that the conductors 12a, b can be guided in the sealing strip 24.
[0167] FIG. 8a-e show an embodiment of a sealing of a longitudinal or transverse edge with a peeling of the carrier layer 2 and a folding over of a longitudinal edge 22c, as is known from the state of the art. The contacting of conductors through the sealing seam is shown as an example in FIG. 8a-e. FIG. 8a-e each refer to a cutout 30 in the area of the sealing seam 28.
[0168] FIG. 8a shows a cutout along a sealing seam, e.g. along the longitudinal edge 22c. The laminate is formed from carrier layer 2, an outer top layer 4, an inner top layer 6, a barrier layer 8 as well as hardfacing layers 26a, b. The laminate is made up of the following layers: the carrier layer 2, an outer top layer 4, an inner top layer 6, a barrier layer 8 and hardfacing layers 26a, b. FIG. 8a shows how two opposite longitudinal edges are laid on top of each other, with one edge folded over in the area of a sealed seam 28. In the area of the sealing seam 28, the top layer 6 of a first longitudinal edge thus lies directly against the top layer 6 of the second longitudinal edge. At this direct contact, the wearing courses 6 are sealed together.
[0169] FIG. 8a also shows that in the area of the sealing seam 28, the carrier layer 2 is tapered, for example by peeling.
[0170] FIG. 8a shows, for example, a ladder 12a resting on an outer top layer 4. The ladder 12a rests on the inner surface layer 6. In the area of sealing seam 28, conductors 12a and 12a overlap in such a way that an electrical contact can be formed. An electrical contact formed in this way makes it possible to form an electrical line between an inner side of a package and an outer side of a package. However, the sealing seam 28 keeps the packaging sealed.
[0171] FIG. 8b shows another embodiment example in which the separation area 14 in the barrier layer 8 is also arranged in the area of the sealing seam 28. If the separation area 14 or also an opening 18 in the area of the sealing seam 28, this has no negative effect whatsoever on the tightness of the barrier layer 8. In the area of the sealing seam 28, the barrier layer 8 lies twice on top of each other and the sealing seam 28 thus represents an extremely tight barrier. A separation area can also be provided cumulatively or alternatively in the area of the barrier layer 8, which faces the interior of the packaging, in particular the product. The separation area 14 can thus be in the area of the barrier layer 8 in which the peeling takes place. The separation area 8 can be in the outer layer of the package sleeve, which is covered by an inner layer. Alternatively or cumulatively, the separation area 14 may be in an inner layer of the sleeve, which is directly in contact with the inside of the package, in particular the product.
[0172] FIG. 8c shows another example in which a contact element 20 breaks through some of the layers in the area of the sealing seam. In particular, the contact element breaks through the two barrier layers 8, which lie on top of each other in the area of the sealing seam 28. Two contact elements 20 arranged next to each other can also break through the barrier layer 8. A separation area can be provided between the contact elements 20 in the barrier layer 8 in any position of the package sleeve.
[0173] The contact element 20 can also be partially insulated in the arrangement in FIGS. 8c and d and also independently of this. In particular, a first end of the contact element 20 may be coated with an insulator or formed from an insulator and a second end may also be an electrical conductor, e.g. metal. The head of the contact element 20 can be made of a metal or a plastic. The end facing the head can be electrically insulating. The tip, i.e. the end facing away from the head, can be electrically conductive.
[0174] FIG. 8d shows another embodiment in which the contact element 20 breaks through the barrier layer 8 from above with its plate-shaped head and also breaks through the lower barrier layer 8.
[0175] FIG. 8e shows another embodiment of contacting a sensor 10 arranged on an inner top layer 6. For this purpose, the sensor has 10 wires 12a, 12b, which are led up to the barrier layer 8. The barrier layer 8 is divided into two areas by a separation area 14 and in each of these areas a conductor 12a, 12b is led up to the barrier layer 8. The two conductors are each contacted with 12a, 12b conductors arranged on the inner top layer 8, which in turn are contacted with 12a, 12b conductors arranged on the outer top layer 6. This allows through-plating in the area of the sealing seam 28 from the inside of a package to the outside of the package.
[0176] FIG. 9a-e again shows a layered structure of a package material formed from a top layer 4, a carrier layer 2, a barrier layer 8 and a top layer 6. The barrier layer 8 is each surrounded by an adhesion promoter layer 26, which can in particular be formed as an insulator. The top layer 6 preferably faces the interior of a package, whereas the top layer 4 faces the exterior of the package.
[0177] FIG. 9a shows a possibility of separating the barrier layer 8 along a separation area 14. A sensor 10 can break through the inner top layer 6 in an area 10a and thus carry out a direct measurement. However, it is also possible that the sensor 10 performs only indirect measurements and is not in direct contact with the product to be packaged. Starting from the sensor 10, 26 lines 12a, b can be formed on the adhesion promoter layer, which break through this layer 26 and are connected to the respective areas of the barrier layer 8. On the outside of the packing, conductors 12a, b can also be connected to a transmitter 16, which is arranged on the outer adhesion promoter layer 26 and thus lies within the carrier layer 2.
[0178] FIG. 9b shows another embodiment in which the barrier layer 8 is perforated by openings 18, which can be round, for example, punched. The conductors 12a, b are guided through these openings in an insulated manner and contact the sensor 10 with the transmitter 16.
[0179] FIG. 9c shows another embodiment in which the sensor 10 is arranged on the inner surface layer 6. The barrier layer 8 is divided in two by a separation area 14. Conductors 12a, b contact the sensor 10 with the two parts of the barrier layer 8. A transmitter 16 applied to the barrier layer 8, which can be insulated from the barrier layer 8, is contacted with conductors 12a, b at the respective areas of the barrier layer 8, so that a two-pole connection is formed between the sensor 10 and the transmitter 16.
[0180] FIG. 9d shows a similar embodiment as FIG. 9c. In contrast, the sensor 10 is arranged inside the inner top layer 6 and the transmitter 16 rests on the barrier layer 8.
[0181] FIG. 9e shows another embodiment in which a separation area 14 divides the barrier layer 8 into two areas. Each area is connected to a conductor 12a, b of the sensor 10 and a conductor 12a, b of the transmitter 16.
[0182] FIG. 10a shows an embodiment in which a conductor 12a rests on the barrier layer 8 isolated from the barrier layer 8. A conductor 12a rests on the carrier layer 2. A contact element 20 can break the conductors 12a, a and simultaneously the carrier layer 2 and the barrier layer 8. The contact element 20 is preferably electrically insulated from the barrier layer 8.
[0183] FIG. 10b also shows an embodiment in which the conductors 12a, a rest directly on the barrier layer and are especially insulated against this. A contact element 20, which breaks through the conductors 12a, a, allows the overlapping conductors 12a, a to be contacted.
[0184] The contact element 20 is preferably insulated from the barrier layer 8 or guided in an opening 18 of the barrier layer 8.
[0185] FIG. 10c shows another embodiment in which conductor 12a, for example, is printed on the inner top layer 6. The contact element 20 pierces this conductor 12a and thus contacts the overlapping conductor 12a. A contact pin of the contact element 20 also breaks through the barrier layer 8 and thus contacts the conductor 12a with the barrier layer 8. A separation area 14 is provided in the barrier layer 8 so that the barrier layer 8 is divided into two areas. In the other area a similar contact can be made with a conductor 12b and a further contact element 20. The contact element 20 can project into the carrier layer 2.
[0186] FIG. 11a shows a transmitter 16. It can be seen that the transmitter 16 has an antenna structure 16a as well as a processor 16b and, if necessary, a memory.
[0187] Such a transmitter 16 can, for example, be mounted on a foil web 32 and arranged at defined distances from it. Such a foil web 32 can be used in the manufacturing process to apply a transmitter 16 to carrier layer 2 or top layer 4 for one blank at a time. The same applies, of course, to a sensor 10, which can be applied in a similar way to the top layer 6 or the barrier layer 8.
