Fig. 1 in the accompanying drawing shows the front elevation according to the electronic of the embodiment of the invention, and this electronic integral body is referred to by arrow 100.Seal 100 comprises cover 1, has the bolt 2 of head 3, and button 4.Cover 1 has crooked positive 1a, and comprises planar section 1b alternatively, can place bar code or other indicator on it.Cover 1 comprises shoulder 1c, and when bolt was in the position that cover 1 is fastened on the container, described shoulder extended to bolt 2, and this point will be described in detail following.Shoulder 1c can with the arc recess 1d termination of the peripheral shape complementation of bolt 2.
The viewgraph of cross-section that passes cover 1 and bolt 2 along the line AA of Fig. 1 is shown in Figure 2, figure 3 illustrates the viewgraph of cross-section of the line BB that passes Fig. 1.
Cover 1 comprises the container that is used for transponder (at Fig. 2 and 3 not shown), and this container makes transponder remain on the appropriate location.In a preferred embodiment, this transponder receptacle is the shape of anchor clamps 50 of the part of clamping transponder.The described part of the transponder of anchor clamps 50 clampings can be one or more antennas.Certainly, also can use or require the transponder receptacle of other form, this depends on the given shape and the configuration of employed transponder.Seal 100 can be particularly suitable for using with passive transponder, and this has represented highly preferred embodiment of the present invention, although the present invention also can be applicable to have the seal of active transponder.
Anchor clamps 50 comprise two parts 50a and 50b, and these two parts are gathered so that transponder is held between the two, and described transponder is suitable radio frequency identification equipment (RFID).Before RFID being placed in the anchor clamps 50, button 4 is inserted in the medium pore 50c of anchor clamps 50.The remainder of cover 1 is crossed molding (over-moulded) around anchor clamps 50.During crossing moulding process, can come support fixture 50 by mechanical support with known manner, removing of these mechanical support produces hole 1e in cover 1.In order to keep anchor clamps 50 to have uniform thickness in the zone of planar section 1b, anchor clamps 50 can have comb shape (comb shape) 1f in this zone.
Make that RFID is inserted in the anchor clamps 50 in case cover 1 shape is formed, and cover 1 remainder and be molded into around the anchor clamps 50, under the situation of not destroying cover 1, RFID can't be removed from covering 1.This is that seal 100 is to its one side that contributes as the feature of tamper evident seal.
Fig. 2 and 3 also shows the xsect that passes sealing mechanism 5.Sealing mechanism 5 among this embodiment is suitable for holding bolt 2.Therefore, seal 100 illustrated in the accompanying drawings for example is suitable for door by the container that uses bolt 2 to pin to close and seals the valuable article that can be pinned by bolt 2, in this case, can make bolt 2 insert two eyes that pass container door, enter then in the sealing mechanism 5.It is known being used for also keeping the mechanism of bolt securely with bolted joints, therefore is not described in detail at this.May need seal 5 is out of shape and/or revises to seal other valuable article.
In the embodiment shown in the figures, second 5c part formed by anchor clamps 50, and another part is formed by sealing mechanism 5, comprises movably member 6, described member 6 comprises the hole 6a that passes this member, and has the opening 6b in the frustoconical shape of holding bolt 2 of the side of hole 6a.In Fig. 2, also be provided with opening with opening 6b analogous shape at the opposite side of hole 6a, but this and nonessential.When bolt 2 is mobile along being directed downwards shown in the arrow A, the sidewall of bolt 2 contact openings 6b, and force movable member 6 to move along the indicated direction of arrow B.Be somebody's turn to do the power contrary that moves with bias device, described bias device is thrum spring 7 here, and it can extend between movable member 6 and cap 8, and engages regularly with sealing mechanism 5.Spring 7 can be any suitable bias device or material, comprises coiled metal or plastic tape, and flexible soft material such as rubber.In addition, spring 7 can be substituted or be additional to another bias device and use, and described another bias device can operate the reverse direction pulling movable member 6 along arrow B, and this device may be the flexible material that extends between movable member 4 and second 5c.
Conducting ring 9 is set at the far-end apart from cap 8 of movable member 6.Conducting ring 9 is by annular moulding, and the chip that is dimensioned on RFID extends, this chip of short circuit thus, and prevent that RFID from sending the signal that signal is addressed inquires in response.Can use any suitably shaped electric conductor to replace conducting ring 9, as long as when this electric conductor contacts with RFID, this electric conductor can make RFID not operate effectively.
Before using seal 100 pinning containers, because conducting ring 9 pushes RFID under spring 7 effects, RFID is maintained at not operable state.Have only when the bolt 2 hole 6a by movable member 6 inserts among the container 5b, RFID just becomes operable state.As can see from Figure 3, conducting ring 9 is in the plane of intersection 50a, 50b of anchor clamps 50.The spring constant of spring 7 should select enough height so that conducting ring 9 keep with RFID on the contacting of necessary conductor so that RFID is inoperative and enough low so that do not cause destruction to RFID.In order further to help to prevent to destroy, movable member 6 can have the flex section along this member, so that for example absorb the vibrations that put on seal 100 during launching.This flex section can be carried out the dual-use function that point of weakness is provided in movable member 6, the detailed explanation that this point will be carried out in conjunction with Figure 11 hereinafter.
Therefore, seal 100 of the present invention makes RFID remain on not operable state, is applied to container up to seal 100.When this control seal 100 can send in response to the signal of addressing inquires to signal.
Fig. 4 shows the front elevation of seal 100, and wherein bolt 2 is inserted among the container 5b.Fig. 5 shows the viewgraph of cross-section of the line CC that passes Fig. 4, and Fig. 6 shows the viewgraph of cross-section of the line DD that passes Fig. 4.As specifically finding out from Fig. 4, when bolt 2 was inserted into container 5b, cover 1 upwards reached the head of bolt 2.This has stoped approaching to bolt 2, thereby has stoped the situation incision Broken bolt at not obvious destruction cover 1.Promptly allow to bolt is not destroyed cover being disconnected below 3 near head, the axle of bolt 2 will extend through valuable article, and removes the shoulder at least that axle may still must destroy cover 1.
Technician in the correlative technology field will understand, and have multiple alternative method to make transponder remain on not operable state, and then transponder be changed into operable state.The method that can be used for seal of the present invention can be indicated by employed particular transponder.For example, can use with the method diverse ways that is used for non-passive transponder and encourage active transponder to be in work or off position, and have different structure and functional transponder and can be energized to be in by distinct methods and can operate or operable state not.The operating in of seal that changes the state of transponder can be mechanical in essence, for example by mobile electric conductor; Or electronics, for example by changing the chip status of realizing the simple state machine.No matter use which kind of motivational techniques, seal of the present invention all has such advantage, promptly need not be in out (on) state consistently, and needn't switch to out (on) state by independent action, described independent action is independent of seal of the present invention and is sealed with the normal use that is worth article.
Fig. 7 shows the front elevation of RFID 200.RFID 200 comprises chip 201 and antenna structure 202, and described antenna structure is in cross in shown preferred embodiment.Supporting construction 203 can provide with the shape of covering the ribs of plastic on 1.Antenna structure 202 can comprise that two or more independent antennas are to help to increase effective range and/or the effective overlay area of RFID 200.For example, an antenna structure can be used for each arm or every pair of arm of the cross-shaped antenna structure 202 shown in Fig. 7, so that displacement 90 degree each other of the antenna in the antenna structure 202.Chip 201 and antenna structure are set on the flex substrate 204.Technician in the association area is with the very fast understanding RFID 200 of type shown in the shop drawings 7 how, therefore, the structure of RFID 200D and operation (any other transponder that perhaps can be used as the part of electronic of the present invention) will not be described further at this.
Cover 1 can be with RFID 200, and perhaps antenna structure 202 is set to sealing mechanism 5 spaced apart at least.This makes antenna structure 202 spaced apart with bolt 2 and valuable article, and described valuable article can be metal containers.Can select gap size between RFID 200 (and/or antenna structure 202) and the bolt 2 (and/or valuable article) to obtain the performance of improved RFID 200.
For discharging seal 100, the operator inwardly shifts button 4 onto shown in Fig. 9 and 10 position from the position shown in Fig. 5 and 6.Fig. 9 and 10 passes the line EE of Fig. 8 and the cross-sectional view of FF.This causes the edge, is one group of tusk 4a among the present invention, moves into axle 5c, thus chip 201 is cut off from substrate 204, and this substrate is remained by anchor clamps 50 and is in the appropriate location.This makes RFID 200 for good and all can not operate.Button 4 inside further actions make the inside surface of button 4 contact the outside surface 10 of engaging mechanism 5a, and this makes engaging mechanism 5a and anchor clamps 50 be disengaged.This allows cover 1 to be removed.The flexible pressure that is provided by the 5a of specific engagement mechanism shown in the accompanying drawing may promote cover 1 away from sealing mechanism 5 in auxiliary being enough to down that does not have the operator, and this leaves and reaches the not degree of joint again of engaging mechanism 5a that makes at least.
In another embodiment of the present invention, button 4 can be replaced by the locking cylinder that is started by key.The rotation of the locking cylinder that is caused by key mechanically or electronically even chemically for example by discharging the chemical substance of destroying transponder, perhaps by causing little themopositive reaction or blast, causes the destruction or the change of transponder.
In another alternative embodiment, seal 100 can be for example by detecting the cut-out of bolt, by detecting the change in electrical characteristics of bolt 2, and/or by twining filament around cover and/or bolt, and the cut-out that detects filament is monitored bolt 2 and/or is covered 1 integrality.After detecting the incident that indicator seal 100 may be removed or distort, seal 100 changes transponder in detectable mode.
In the described here preferred embodiment, under the situation of not first press push button 4, cover 1 can't be removed, and press push button 4 causes RFID 200 destroyed.The advantage of present embodiment is that the destruction of the chance of RFID 200 will be seldom.In alternative embodiment, button 4 can be left in the basket, and covers 1 and can be removed under the situation of not first press push button 4 or any other driver.In this alternative embodiment, the behavior of removing cover 1 may destroy or change transponder, for example be fastened to the part of the antenna on the cover 1 by dismantling, and stay the chip of transponder, the perhaps behavior of removing cover 1 by the disconnection of monitoring electronic circuit, wherein, the border between the remainder of described circuit extend past cover 1 and seal 100.
Therefore, no matter be the signal of not receiving from RFID, if still whole seal 100 is replaced, will receive incorrect signal, seal 100 all is anti-tamper.Because can not be by cover 1 near bolt 2, perhaps be at least under the situation of not destroying cover 1, be difficult near and cut off bolt 2, so seal 100 obviously is anti-tamper, and is difficult to overcome the tamper-evident means in the seal 100.
Figure 11 shows according to the summary of the part of alternative seal of the present invention and represents.The part of shown seal is a movable member 60, is similar to the movable member 6 of seal 100; Cover 65, be similar to the cover 1 of seal 100; And RFID 64, it can be RFID200 shown in Figure 7.Movable member 60 comprises weakening part 61.This weakening part 61 is set at conducting ring 62 and holds in the movable member 60 between the hole 63 of bolt (not shown) (invisible among Figure 11).Conducting ring 62 is to work with the same mode of the conducting ring 9 of seal 100, so that RFID64 can not operate when it contacts with RFID 64.
Movable member 63 can pass through any suitable bias unit, comprises that the spring that is similar to spring 7 is to RFID 64 biasings.In addition or replaceablely be, movable member 63 is by being fastened to two biasing members 66 on the cover 65 to RFID 64 biasings.Weakening part 61 and biasing member 66 form by suitable material and with suitable shape and size, make the elasticity of this weakening part 61 and biasing member 66 make that weakening part 61 is cut off under cover 65 situations of removing from movable member 60 (it remains on the appropriate location by bolt).Along with weakening part 61 is cut off, biasing member 66 is pushed conducting ring 62 to RFID 64 then, makes RFID 64 to operate.Cover is 65 by moulding, makes to remove conducting ring 62 and have only by destroying cover 65 and could realize from covering 65.
Those skilled in the relevant art will understand, and have the alternative bias device that can be used for substituting biasing member 66, for example metal spring.Also having, is under the situation of EEPROM or similar device at RFID, and seal can be monitored the removal of cover 65 and be wiped EEPROM.This can realize that by the disconnection of monitoring one or more conductors weakening part 61 can be omitted in this case.
As can see curved bending of RFID of having given in the insertion anchor clamps 50 of cover 1 best at Fig. 3,6 and 10.RFID 200 and anchor clamps 50 boths are dimensioned, and when making within RFID 200 is placed in anchor clamps 50, chip 201 is in central authorities with respect to ring 9.
Because anchor clamps 50 are curved, this forces again and form bending in substrate 204, and it causes crooked antenna structure 202.The bending of antenna structure 202 causes covering transmitting of certain section (being formed by the ray from the active part of antenna structure 202 normal direction extend past antenna structures 202).This and antenna keep straight situation opposite, under the straight situation of antenna, most of energy of being launched will with antenna plane laterally from the antenna directed outwards.The advantage of crooked Antenna Design is that interrogator may be placed with towards cover 1 one sides, and still in useful distance received signal.This double-antenna structure by RFID 200 is further enhanced.
Technician in the association area will understand, and when antenna was bending, the effective transmitting range that is used for RFID 200 was reduced on the normal direction of the vertical center line of the positive 1a of cover 1.Yet this effective transmitting range defending party to the application who reduces is considered as remedying by the advantage of the effective transmitting range that has the essence increase on other direction.For example, when seal 100 was used on the big container, common way was with the placement closer to each other of two or more containers.The inquiry person that can stop RFID 200 like this is effectively approaching from the front of seal 100.The curved shape of RFID 200 in the seal 100 allows RFID 200 to be addressed inquires at coverage from other direction, for example by placing a transponder in the space between two containers.
Technician in the association area also will understand, has the transponder receptacle of curved shape by forming along two orthogonal axes, for example by forming para-curve or spherical surface, the effective coverage of transponder can increase along two orthogonal axes, thereby there is further dirigibility the position that allows to be used for the interrogator of passive transponder/the be used for receiver of active transponder.In addition, although preferred embodiment is crooked transponder receptacle, the technician in the association area also will understand, and other shape also allows with respect to the effective transmitting range on the increasing angles scope of the transponder with flat plane antenna.For example, transponder receptacle can limit three trapezoidal limits.
In addition, cover 1 curved shape plays the effective angle that increases emission, stop near sealing mechanism 5, and outside these three the useful purposes in the surface that RFID 200 is orientated next-door neighbour's sealing part that can be mounted from seal 100.Realize that two purposes in these purposes also can cause with respect on the material of alternative mode and the efficient of manufacturing cost even utilize single structure.Can realize covering the advantage of 1 curved shape, no matter cover 1 and whether can come to remove by using button or other driver from sealing mechanism 5.Can not remove from sealing mechanism 5 if cover 1, they may be integrally to form so, and in this case, the operator must destroy cover with near bolt 2 (or other locking component).Weak line can form in seal 100, to help removal and the integrally formed cover of sealing mechanism.
The formation of non-planar antennas structure can be applied in any other technology of introducing transponder, and this respect of the present invention should not be understood that to be limited to the use on electronic, although the applicant believes that when it is applied to electronic be to have special use.
