At this moment should be noted that container or jar 10 can be the structures of any kind, traditional jar for example illustrated in figures 1 and 2, or have any other type hollow container of at least one wall portion that forms by metal.According to the size of container with constitute the amount of metal of container, label can be traditional structure, for example the eas tag of conventional construction or the larger area that the can be structure according to a further aspect of the invention label of annular for example.A this label is the example tag 200 shown in Fig. 3.

Before describing multiple holding unit of the present invention in detail, brief description jar 10 and label 200 in order.For this reason, can Fig. 1 and Fig. 2 see container or jar 10 comprise substantially columniform middle part or sidewall 10A, roof 10B, diapire 10C (Fig. 2), sidewall and roof intersection around the periphery of sidewall 10A extend on crimping 10D and the Rolldown hem 10E that extends around the periphery of sidewall at sidewall and diapire intersection.Sidewall is a tubular part, this tubular part can by have metal for example the cardboard of aluminum liner (not shown) form, or can integral body be made of metal, for example aluminium.Roof or lid 10B are the basic flat components of circular contour, and can be made of any suitable material, for example aluminium.Except roof can be configured to: for example have the dotted line 10F that extends around its periphery, thereby remove roof from container and used material the container to be convenient to tear by it, diapire or bottom 10C have the structure similar to roof 10B.For this reason, roof or lid 10B can comprise traditional draw ring 12.Crimping 10D is identical structure with 10E, and for example each is all formed by aluminium.Crimping 10D is in order to be fixed in sidewall 10A with lid 10B regularly.Equally, crimping 10E is in order to be fixed in sidewall 10A with bottom 10C regularly.Here be noted that if necessary the metal of container 10 part also can be formed by other metallic material except aluminium.

Example tag 200 of the present invention will be described after a while.Be enough at present illustrate this label with by cessionary Thorofare of the present invention, (the CheckpointSystems of Checkpoint Systems, Inc. of NJ, inc.) active/passive of Chu Shouing (activatable/deactivatable) frequency sweep eas tag is structurally similar, bigger dimensionally and be the circle except this label, thereby when this label passes through according to erecting equipment of the present invention, for example be similar to the equipment of equipment 20 among Fig. 4 A, when being installed on the container, make lid 10B that this label can covering container 10 or most of area of bottom 10C.Especially, safety label 200 in the exemplary embodiment shown in Fig. 3 have with patent No. be 5,081,445 US Patent certificate (United statesletters patent) (" ' No. 445 patents ") basic structure that disclosed label is identical, this US Patent has transferred Checkpoint Systems, Inc. and has incorporated its disclosure into as a reference at this, following exception: the diameter of label 200 is 3 inches to 4.5 inches, yet ' label of No. 445 patents has the face area of about 2.5 sq ins.And label 200 is circular, and ' label of No. 445 patents be square.Compare with square or rectangular label, circular label 200 makes the label unit area more effective.

Thereby high and be suitable for the space hour of label when the energy requirement of label, circular label is more desirable.Otherwise, can use square or rectangular label in the position of circular label.Yet for specific application, face area square or rectangular label must be greater than circular label.If container is different shape, the part of positioning label on the container for example, first-selection is suitable for the circular label of the maximum of this shape.

It should be appreciated by those skilled in the art that by using possible maximum label, can reduce the influence of container metal part the signal that feeds back to receptor.Yet, although bigger label will be more powerful, make more expensively, in experiment, provide the actv. signal power with the label of 11.4 sq ins.In addition, it is different to compare the inductance and the electric capacity of circular label with square label.

Now turn to Fig. 3, consider the details of example tag 200.Can find out that label 200 comprises that substantially pair of conductive figure or conducting wire (will after this describe) are to form tag circuit.In the exemplary embodiment of Fig. 3, label 200 is the EAS resonant of coil L and a pair of capacitor C 1 and C2 form, constitutes these electronic building bricks with the conducting wire.Especially, label 200 comprises first conducting wire 202 and second conducting wire 204.Described circuit is formed by any suitable conducting material, for example aluminium.First conducting wire 202 is the spiral coil form, and it longly has a constant width to this spiral coil except its

end

202A and 202B outer.Line chart forms inducer L.End 202A in the inner of coil 202 have expansion as bulbiform zone to form first plate that first cond is cond C1.End 202B in the outer end of coil 202 also expands as and forms second cond is first plate of cond C2.Second circuit 204 is arranged on first circuit and is that prolong, linear substantially band, and it grows and has constant width this band except its

end

204A and 204B outer.The end 204A with the inner of 204 have expansion as bulbiform zone to form second plate of the first cond C1.Also has the zone of expansion to form second plate of the second cond C2 at end 204B with 204 outer end.The dielectric layer 206 of a part only is shown, and for example polyethylene film is put between two conducting wires 202 and 204.Dielectric layer 206 is as the dielectric between each plate of the first and second cond C1 and C2.

The electrical characteristics that it will be understood by those skilled in the art that the resonance circuit that is made of

circuit

202 and 204 can constitute the shape of described circuit and/or material and/or constitute the thickness and/or the material of dielectric layer 206 by change adjusted by change.The adjusting of the electrical characteristics of described label is very important, uses with special container structure and holding unit structure so that this label can suitably be demarcated, and this will be elaborated after a while.

Label 200 can be installed on the ply of paper or on some other substrates, for example substrate 208, so that label be easy to be fixed in holding unit constructed according to the invention or be fixed in will be by the commodity that identified (if holding unit be nonessential, if for example container does not comprise any metal part, wherein label is placed on this metal part).In order to make label be easy to be fixed in holding unit or to be fixed in commodity itself, substrate 206 can comprise the adhesives (not shown) thereon.

When being installed on the container 10 by erecting equipment constructed according to the invention, label 20 is particularly suitable to be used in traditional EAS safety system.For example, traditional EAS equipment for example comprises that the RF pedestal of transceiver can be in order to be created in the so-called frequency sweep RF signal in the required bandwidth.The inductor/capacitor circuit of label 200 is at the frequency wavestrip interior resonance of being launched, for example about 8.2MHz+/-0.5MHz.Non-demagnetization label (non-deactived) within institute RF signals transmitted field makes this signal distortion and this distortion partly be detected by the receptor of transceiver, produces alarm then.Yet,, can not produce alarm signal inside the time when this label so if this label is demagnetization (deactived).

Turn to Fig. 4 A and Fig. 4 B again, structure and operational detail according to the exemplary embodiment of the label holding unit 20 of structure of the present invention now will be discussed.Can find out that for this reason holding unit 20 comprises cap substantially, this cap is set to be fixed in container 10 and above its lid or roof 10B.This is only exemplary, because this cap can easily be fixed on bottom or the diapire 10C.

When standing (exposed to) from the rf interrogation signal of the rf antenna of the traditional E AS pedestal under the Liberty PX trade mark of for example selling by Checkpoint Systems, Inc., if the signal strength that 410 labels feed back in free air has been set up reference 1.0 units, signal of tag feedback so of the present invention with intensity of 2.5-6.0 unit.Can imagine the higher-strength of technical limitation permission.Because can has screening effect to feedback signal, this signal strength needs bigger.Thereby, make that the feedback signal of label is strong so that receptor can receive the signal understood (intelligible signal) from label.

Each, cylinder, jar or container have different broken ring abilities to the magnetic field that is produced by label.Usually, container disturbs the frequency of label resonance and reduces signal amplitude.Capacitance by changing label or inductance value can improve container with the signal that increases or reduce label resonance.The infringement of losing for the label signal that will cause because of the metal of container minimizes, and this label and vessel isolation are opened.Although the peculiar property of container will determine how far labeling requirement is isolated, label usually will with container top 1cm at least at interval.Container is far away more, and signal strength is strong more.With produce label should segregate distance and two steps of label construction restriction merge.New label design is: make that the transceiver that is used for safety label can detect signal when it is put on the can.

Label design can feedback signal for when being connected to the can device on the time, and the meaning is that the requirement signal is enough by force so that standard pedestal type transceiver time can detect signal in standard pitch (4-6 foot).An example of standard transceiver is an outpost of the tax office Liberty PX pedestal.

As mentioned previously, finished product, have promptly that holding unit supports safety label thereon and with the container of vessel isolation, make by following process: label is inserted cap, isolation layer is placed on (if holding unit utilizes the isolation layer parts) under this label, cap is placed on the lid of container and preferably adhesive closure or packing material is placed on cap and the container.Alternatively, cap can be placed on the bottom of container, and place a standard cap at the top of this device.Perhaps can place a labeled cap in the top and the bottom of this device.

Utilize special-purpose cap or label holder and identified according to the above-mentioned an aspect of of the present present invention that should be understood that, this cap inboard has metal top, lid or the cap that can effectively make label and container one isolation layer of giving set a distance is arranged.The obvious like this screening effect that reduces the metal construction of container to the label resonance signal.If there is not isolation layer, container can hinder or the feedback signal of label is seriously reduced.

Should be understood that according to above-mentioned those skilled in the art, the present invention includes several respects, for example: holding unit, thereby this holding unit alternatively within it side have isolation layer so that safety label and container metal part are divided isolates to such an extent that the signal understood that receives by receptor enough far is provided; Safety label, thus this safety post is signed with enough big power and can correctly demarcates in the middle of distortion and the shielding that partly caused by the container metal and beam back discernible signal to transceiver; And the method for utilizing holding unit of the present invention on container, to design and demarcate the safety label of the work that is suitable for at least one metal part.At this moment it should still be noted that, although being a kind of effective sign, the label shown in use Fig. 3 has the method for optimizing of the container of metal part, but in some cases,, can use the safety label of conventional construction and shape according to the structure of container/jar and the size of label.
