Tag 1 comprising a head 2 supporting an antenna 3, a tail 4 adapted to overlie and capacitively couple with the liquid, a resonant loop 5 between head and tail, and a chip 6 adapted to be powered by the loop. In use the tag is interrogated by a tag reader to read information about the container and/or liquid contents. The head, antenna, tail and loop are preferably formed as a single sheet of material.

Description

TITLE. Container with Liquid and RF Tap The present invention relates to a container with liquid and an RF Tag.
It is known to use an RF tag on bottles such a wine bottles, as described in 0B2493996. Such tags have a resonant loop with one end directly connected or capacitively coupled to a metal foil cap on the bottle and another end capacitively coupled to the liquid in the bottle. A problem with this is that the foil cap is an essential to make the RF Tag work as it absorbs energy from a tag reader to power the loop, and hence such an RF Tag does not work with containers without a metal foil cap.
The invention seeks to provide a solution to this problem.
According to the present invention there is provided an RF Tag for a container with liquid having an insulating gap between the top of the liquid and the top of the container, said tag comprising a head supporting an antenna, a tail adapted to overlie and capacitively couple with the liquid, a resonant loop between head and tail, and a circuit adapted to be powered by the loop, said antenna being in use above the top of the liquid, in use the tag being interrogated by a tag reader to read information about the container and/or liquid contents.
Preferably the antenna is formed of a single sheet of material Preferably the head and antenna, tail and loop are formed as a single sheet of material.
Preferably the tag is supported on a backing sheet. The backing sheet may be self-adhesive.
Preferably the antenna has a coil to form a tuned antenna. Preferably the antenna has one end extending from the head and a remote free end.
The remote free end may have a widened portion to capture the electric field of a tag reader. The remote free end widened portion may include one or more capacitive contact points along its length to engage with any metallic packaging material on the container.
Preferably the antenna has a pair of sub coils either side of a capacitive contact point.
Preferably the tag is elongate.
Preferably the tag has a length approximating to a fraction of (e.g. one quarter) of the wavelength of the interrogating signal.
Preferably the container has an aperture with a closure device above the liquid, and the tag is adapted to extend over the closure whereby opening of the closure damages the tag.
The tag may further comprises a tamper loop which is damaged upon opening of the closure. The tamper loop may be connected directly to the chip.
The container may be a bottle such as a glass or plastics bottle.
An embodiment of the invention will now he described with reference to the accompanying drawings in which: Figure 1 shows a view of a tag, Figure 2 shows a view of a bottle top with the tag of Figure I, and Figure 3 shows a view of an alternative tag shown in Figure 1.
Referring to Figure 1 there is shown a UHF RF tag 1.
An elongate tag I has a head 2 supporting an antenna 3, a tail 4, a resonant loop 5, and an integrated circuit in the form of a chip 6 powered by the resonant loop 5. Tag 1 has its head tail and antenna formed of a single layer of conductive material and may be supported on a backing sheet X with self-adhesive to adhere the tag and its backing sheet to a container such as a bottle (see Figure 2).
The antenna has a coil, in the form of a pair of sub-coils 3A,3B either side of a capacitive contact point 3C, to form a tuned antenna so that it can be shorter. The antenna 3 has sub-coil 3A at one end extending from the head 2 and a remote free end 3D. Free end 3D is a widened elongate strip to capture the electric field of a tag reader more efficiently.
The remote free end widened portion strip may include one or more capacitive contact points 3E,3F,3G along its length to engage with any metallic packaging material on a container.
As shown in Figure 2, tag I can he placed over the top of a container such as a plastics bottle 10 with neck 11 leading to an aperture at the top of the bottle with a removable screw cap closure 12. Plastic bottle 10 may contain a liquid "A" with an insulating gas gap "B" of air or the like.
Tag I is placed over the top of the bottle with tail 4 overlying and hence capacitively coupled to the liquid. The antenna 3, loop 5 and chip 6 is ideally above the liquid "A", and the antenna 3 extends over the cap closure 12.
In use the tag being interrogated by a tag reader to read information about the container and/or its liquid contents. Energy from the tag reader is absorbed by the antenna free end 3D, and a conductive flow path is established through the antenna 3, through head 2, through the resonant loop 5, and into the liquid through the tail 4. This allows the resonant loop to provide a power source for the chip 6.
The coil provided by sub coils 3A,3B are tuned to the wavelength of the tag reader with the length of the antenna chosen to be a fraction of (e.g. one quarter) the wavelength of the interrogating signal so that the antenna can he short. if desired the free end 3D of the antenna can be cut shorter, e.g. removing contact points 3F,3G.
Tag 1 is adapted for use with containers without a metallic cap such a foil cap used on wine bottles. If however it is used with containers with a metallic cap, the cap could cover one or more of the capacitive contact points 3C,3E,3F,3G which would couple capacitively with the metallic cap, and the metallic cap would replace a portion of the function of the antenna 3D. A rupturable cut-out 7 may be provided in the loop 5. in the event cap closure 12 is opened with by an unauthorised person before the container is purchased, the tag with tear at the cut out 7 so severing the loop 5 making it non-functioning which can be picked up by a card reader to show that a container has been tampered with.
Figure 3 shows a tag I identical to that in Figure I except that, in addition to or alternatively to cut-out 7, a tamper loop 20 may be connected directly to chip 6. Tag 1 with loop 20 includes a series of perforations 21,22. When fitted to a bottle 10 such as shown in Figure 2, in the event cap closure 12 is opened by an unauthorised person before the container is purchased, the tag 1 and loop 20 will tear at the perforations 21 and/or 22 so rendering the loop and thus chip 6 nonfunctioning which can be picked up by a tag reader to show that a container has been tampered with. Loop 20 may have zig zags 23 to provide inductance.
The invention may take a form different to that specifically described above. For example the tag could be used with containers with liquid other than bottles.
Further modifications will be apparent to those skilled in the art without departing from the scope of the present invention.
