Description

container

The present invention relates to a container according to the preamble of claim 1 and a transponder label according to the preamble of patent claim 6.

Various devices are known from the prior art, which detect the opening state of a container. The integration of a transponder in the cap of beverage bottles is generally complex and expensive, especially if it is to be ensured that the transponder is readable or accessible only after opening the bottle.

It is therefore an object of the present invention to provide a container of the type mentioned, which only allows a responsiveness of the transponder after opening a container such as a bottle.

This object is achieved in a container of the type mentioned by the characterizing features of claim 1. In a container, in particular a bottle made of at least partially non-conductive material, comprising a closure element made of electrically conductive material, an antenna coil and a transponder chip connected to the antenna coil, it is provided according to the invention that the antenna coil is arranged around the container in a region close to the closure element is.

It is thereby achieved that, when the closure element is attached, the magnetic flux through the coil antenna is prevented and the transponder chip can only be addressed after the container has been opened.

Particularly advantageous embodiments of the container are further defined by the features of the dependent claims:

A particularly advantageous embodiment of the container provides that the container is designed as a bottle, preferably made of glass, with bottleneck, wherein the antenna coil on the bottle, in particular the bottle neck, at a distance, in particular less 20 mm, preferably less than 5 mm , is arranged to the closure element. Externally induced electric fields can be attenuated particularly well if the antenna coil along the circumference of the container by an electrically conductive, the antenna coil annularly surrounding, electrically covered cover layer is covered.

The error rate of the containers incorrectly recognized as being opened can be further reduced by arranging the antenna coil on a carrier layer which lies between the container and the antenna coil.

The transponder chip is particularly well addressed only after opening the container when the carrier frequency of the transponder chip between 120 kHz and 150 kHz or in the range between 13 MHz and 14 MHz, in particular at 13.56 MHz is.

It is a further object of the invention to provide a transponder label, which - arranged on the container - the state of a container, whether open or closed, detected by magnetic fields easily.

This object is solved by the features of claim 6. In a transponder label for attachment to a container, in particular a glass or plastic bottle, comprising a number of printed conductors, for forming an antenna coil, which are applied to a carrier layer, and a transponder chip in electrical connection with at least one printed conductor, it is provided according to the invention At the ends of each conductor contact points are formed, wherein the contact points for forming an antenna coil can be brought into electrical contact.

The functionality of the transponder label can be further improved by providing an electrically conductive, annular open cover layer, which is mounted on at least one side of the conductor tracks and with which the conductor tracks are electromagnetically or electrically shielded.

An advantageous embodiment of the transponder label provides that an insulation layer is provided, wherein the insulation layer between the conductor tracks and the cover layer is arranged. The antenna coil of the transponder label is formed particularly simply if in each case the contact point lying at one end of a conductor track is electrically conductively connected to the contact point of an adjacent conductor track located at the opposite end, in particular via gluing or press-connection.

An advantageous use of the transponder label provides that the transponder label is applied to a container, in particular a bottle made of glass or plastic, with a closure element.

Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.

The invention is illustrated schematically below with reference to particularly advantageous, but not limiting exemplary embodiments in the drawings and is described by way of example with reference to the drawings:

Fig. 1 and Fig. 2 respectively show the upper part of a container according to the invention in a perspective view.

Fig. 3 shows an embodiment of the container in section with attached closure element.

Fig. 5 shows the use of a container with attached closure element.

Fig. 6 shows a container with cover layer in section.

Fig. 7 shows an embodiment of the transponder label.

FIGS. 8 and 9 show a further embodiment of the transponder label.

FIGS. 10 and 11 show the use of an embodiment of the invention

Transponder label.

FIGS. 12 and 13 show an embodiment of the contact points.

In Fig. 1 and Fig. 2 are containers, here glass bottles 10, shown with a closure element 2. In Fig. 1, a closure element 2 is shown in the form of a partially made of metal crown cap, in Fig. 2, a screw cap. In Fig. 1 and Fig. 2 each a bottleneck 1 1 of the bottle 10 is wrapped around the antenna coil 3 is attached which is connected to a transponder chip 4.

FIG. 3 and FIG. 4 schematically show the basic operating principle of the bottle 10 shown in FIGS. 1 and 2. The antenna coil 3 has conductor turns, the the bottle 10 in the vicinity of the electrically conductive cap 2 wrap around (Figure 3). If an alternating magnetic field 21 generated by an NFC or RFID reader 13 is directed onto the antenna coil 3 in the case of a bottle 10 sealed with an electrically conductive closure element 2, eddy currents 22 are induced in the electrically conductive closure element 2, whereby the original from the reading device 13 generated magnetic alternating field 21 is weakened. The resulting magnetic flux passing through the antenna coil 3 is then no longer sufficient to allow inductive coupling-based wireless communication between the NFC RFID reader 13 and the transponder chip 4 (FIG. 3).

Only after removal of the electrically conductive closure element 2, after opening the bottle 10, can sufficient magnetic flux pass through the antenna coil 3, so that communication with the NFC7RFID reading device 13 is also possible (FIG. 4).

In practice, the transponder, comprising the transponder chip 4 and the antenna coil 3, can either be prefabricated in ring form and then applied to the bottle neck 11 or incorporated into the container during the production of the container.

The simple arrangement described above, the problem solved, namely the avoidance of a response of the transponder with attached closure element 2 and response of the transponder after removal of the closure element 2, solve particularly well if the distance d of the antenna coil 3 from the closure element 2 low, in particular less than 3 mm - 5 mm. For larger distances d, it may be possible, depending on the specific structure of the reader 13 and the shape of the bottle neck 1 1, that the transponder can already be addressed, although the closure element 2 is still placed on the bottle 10 (FIG. 5). This could, as shown in Fig. 5, for example, by a close contact of the transmitting antenna 24 of the reader 13 to the antenna coil 3 done. As a result, under certain circumstances, sufficient magnetic flux 25 of the transmitting antenna 24 of the reading device 13 can pass through the antenna coil 3 and thus result in undesired response of the transponder chip 4. This becomes more likely the larger the distance d is.

To avoid this undesirable effect, Fig. 6 shows an improved embodiment of the invention. The antenna coil 3 is on one or both Pages covered or surrounded by an electrically conductive cover layer 5. The electrically conductive cover layer 5 is electrically insulated from the antenna coil 3 and in the outer region of the antenna coil 3 along the bottle neck 1 1, arranged annularly. The ends of the cover layer 5 neither overlap and are not electrically connected to each other and are insulated from each other in the overlapping area. The open design of the cover layer 5 prevents the formation of eddy currents in the bottle neck circumferential direction, since this would prevent the response of the transponder chip 4, even with the closure element 2 removed, by the complete shielding of the antenna coil 3 achieved thereby.

Due to the metallic cover of the antenna coil 3, magnetic fields which have a normal component to the bottle neck lateral surface are effectively weakened by the eddy currents 26 induced in the metallic cover layer 5, so that a response of the transponder chip 4 is suppressed when the reader 13 is placed on the side. The antenna coil 3 is electrically insulated from the cover layer 5. The electrically conductive cover layer 5 may be formed in the form of a thin metal layer and be realized together with the antenna coil 3, for example in the form of a multi-layer label. The cover layer 5 does not necessarily have to be outside the antenna coil 3, but can also be located inside, i. indirectly on the bottle

10 facing side of the antenna coil 3 are. Likewise, an embodiment with inside and outside the antenna coil 3 lying cover 5 is possible.

A transponder label 20 for a practically simple and suitable implementation of the invention, which also allows a subsequent application of the transponder in the course of labeling, after filling and the closure of a bottle 10, Fig. 7. The transponder chip 4 and tracks 7 of the antenna coil 3 are realized on a carrier layer 8, here an adhesive label, as a transponder label 20. The transponder tag 20 (FIG. 7) thus produced may, in use, fit snugly along the circumference of a container, such as a glass bottle 10, as shown in FIGS. 10 and 10.

11 are glued, so that the adjacent conductor tracks 7 of the antenna coil 3 are closed via in each case at the end of a conductor 7 formed contact points 9.

11 shows a detail of a transponder label 20 with an outer, electrically conductive cover layer 5 applied to a bottleneck 1 1 in a sectional view. The individual conductor tracks 7 are arranged offset to one another (FIG. 8) and close over the contact points 9 coated with an electrically conductive adhesive layer to an antenna coil 3. The contact points 9 are arranged on the opposite outwardly facing surfaces of the carrier layer 8, for example, each of the contact points 9 of the ends of the tracks 7 inside and the contact points 9 of the beginning of the tracks 7 au Shen or vice versa (Fig. 9) , When the transponder label 20 is attached to a container, the contact points 9 of the start of a conductor 7 come into contact with the contact point 9 of the end of an adjacent conductor 7 (FIG. 11) and thus form the turns of the continuous antenna coil 3 Cover layer 5 encloses the conductor tracks 7 along the circumference of the bottle neck 1 1 completely. The cover layer 5 is annularly open, that is, the two ends of the cover layer 5 are not conductively connected to each other and do not form an electrically closed ring. In order to prevent electrical contact of the ends of the covering layer 5, an insulation 12 is formed on the transponder label 20, as shown in FIGS. 9 and 11, between the conductor tracks 7 and the covering layer 5. Of course, it is possible and practically useful that the transponder label 20 additionally has one or more externa ßere protective or cover layers, for example, to allow any printing.

As an alternative to contacting the interconnects 7 of the transponder label 20 with an electrically conductive adhesive layer, as shown in FIGS. 12 and 13, there is also the possibility of purely mechanical contacting, for example by fusion or compression 14 of the contact points 9.

The frequency range of the data transmission between transponder chip 4 and the reading device 13 in the embodiments of the invention described above is between 120 -150 kHz and 13-14 MHz. Particularly successful is a transmission at a frequency of 13.56 MHz.
